Cautionary Note Regarding Forward-Looking Statements
This Quarterly Report on Form 10-Q (this “report”) includes forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), which are subject to the “safe harbor” created in Section 21E. In particular, statements about our expectations, beliefs, plans, objectives or assumptions of future events or performance are contained or incorporated by reference in this report. All statements other than statements of historical facts contained herein are forward-looking statements. These forward-looking statements can generally be identified by the use of words such as “may,” “will,” “intends,” “plans,” “believes,” “anticipates,” “expects,” “estimates,” “predicts,” “potential,” the negative of these words or similar expressions. Statements that describe our future plans, strategies, intentions, expectations, objectives, goals or prospects are also forward-looking statements. Discussions containing these forward-looking statements are principally contained in the “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” sections of this report, as well as any amendments we make to those sections in filings with the Securities and Exchange Commission (“SEC”). These forward-looking statements include, but are not limited to, statements about:
the preclinical development, clinical development, commercialization, or post-marketing studies of our products and product candidates, including ORLADEYO® (berotralstat), BCX10013, peramivir, and early-stage discovery programs, and our plans regarding the same;
the timing and success of our commercialization of ORLADEYO in the United States and elsewhere and expectations regarding the commercial market for ORLADEYO;
the potential for government stockpiling orders of our products and product candidates, including the timing or likelihood of entering into any U.S. Government stockpile order and our ability to execute any such order;
additional regulatory approvals, or milestones, royalties or profit from sales of our products by us or our partners;
the implementation of our business model, strategic plans for our business, products, product candidates and technology;
our ability to establish and maintain collaborations or out-license rights to our products and product candidates;
plans, programs, progress and potential success of our collaborations, including with Torii Pharmaceutical Co., Ltd. (“Torii”) for ORLADEYO in Japan and Shionogi & Co., Ltd. (“Shionogi”) and Green Cross Corporation (“Green Cross”) for peramivir in their territories;
our and our subsidiary guarantors’ ability to satisfy obligations under the Pharmakon Loan Agreement (as defined below) and to comply with the covenants as set forth in the agreements governing our debt obligations;
the scope of protection we are able to establish and maintain for intellectual property rights covering our products, product candidates, and technology;
our ability to operate our business without infringing the intellectual property rights of others;
estimates of our revenues, expenses, capital requirements, annual cash utilization, and our needs for additional financing;
the timing or likelihood of regulatory filings or regulatory agreements, deferrals, approvals, and other decisions;
our ability to manage our liquidity needs, including our ability to raise additional capital, to fund our operations or repay our recourse debt obligations;
our financial performance; and
competitive companies, technologies, and our industry.
i

We have based any forward-looking statements on our current expectations about future events or performance. While we believe these expectations are reasonable, forward-looking statements are inherently subject to known and unknown risks and uncertainties, many of which are beyond our control. Actual results may differ materially from those suggested or implied by these forward-looking statements for various reasons, including those discussed in this report under the heading “Risk Factors” in Part II, Item 1A, some of which are summarized in the “Risk Factor Summary” below. Any forward-looking statement is subject to these and other risks, uncertainties, and assumptions relating to our operations, results of operations, industry, and future growth. Given these risks and uncertainties, you are cautioned not to place undue reliance on our forward-looking statements. The forward-looking statements included in this report are made only as of the date hereof. We do not undertake, and specifically decline, any obligation to update any of these statements or to publicly announce the results of any revisions to any forward-looking statements to reflect future events or developments, except as may be required by U.S. federal securities laws.
Risk Factor Summary
An investment in the Company involves risks. You should carefully read this entire report and consider the uncertainties and risks discussed in the “Risk Factors” section in Part II, Item 1A of this report, which may adversely affect our business, financial condition, or results of operations, along with the other information included in our other filings with the SEC, before making an investment decision in the Company. A summary of the principal factors that make an investment in the Company speculative or risky is set forth below.
The ongoing novel coronavirus (“COVID-19”) pandemic could create challenges in all aspects of our business, including, without limitation, delays, stoppages, difficulties, and increased expenses with respect to our and our partners’ development, regulatory processes, and supply chains, negatively impact our ability to access the capital or credit markets to finance our operations, or have the effect of heightening many of the risks described below or in the “Risk Factors” section in Part II, Item 1A of this report.
We have incurred losses since our inception, expect to continue to incur losses, and may never be profitable.
We may need to raise additional capital in the future. If we are unable to raise capital as and when needed, we may need to adjust our operations.
Our success depends upon our ability to manage our product candidate pipeline, advance our product candidates through the various stages of development, especially through the clinical trial process, and to receive and maintain regulatory approvals for the commercial sale of our product candidates. The development process and related regulatory processes are complex and uncertain, may be lengthy and expensive, and require, among other things, an indication that our products and product candidates are safe and effective. For example, applicable regulatory agencies could refuse to approve, or impose restrictions or warnings on, our product candidates, require us to conduct additional studies or adopt study designs that differ from our planned development strategies, suspend or terminate our clinical trials, withdraw approval for our products, or take other actions that could materially impact the cost, timing, and success of our planned development and commercialization strategies.
We rely heavily upon third parties, including development partners, contractors, contract research organizations, and third-party suppliers, manufacturers, and distributors, for many important stages of our product candidate development and in the commercialization of certain of our products and product candidates. Our failure to establish and maintain these relationships, the failure of any such third party to perform its obligations under agreements with us, or the failure of such a relationship to meet our expectations could have a material adverse impact on our business, financial condition, and results of operations.
If we fail to obtain additional financing or acceptable partnership arrangements as and when needed, we may be unable to complete the development and commercialization of our products and product candidates or continue operations.
The commercial viability of any approved product could be compromised if the product is less effective than expected, causes undesirable side effects that either were not previously identified or were worse than expected, or fails to achieve market acceptance by physicians, patients, third-party payors, health authorities, and others.
There can be no assurance that our or our partners’ commercialization efforts, methods, and strategies for our products or technologies will succeed, and our future revenue generation is uncertain.
ii

We have expanded, and may continue expanding, our development and regulatory capabilities and are implementing sales, marketing, and distribution capabilities, and as a result, we may encounter difficulties managing our growth, which could disrupt our operations.
We face intense competition, and if we are unable to compete effectively, the demand for our products may be reduced. In addition, developments by others may render our products, product candidates, or technologies obsolete or noncompetitive.
We are subject to various laws and regulations related to our products and product candidates, and if we or our employees, consultants, or partners do not comply with these laws and regulations, we could face substantial penalties and our reputation could be harmed. In addition, we and our partners may be subject to new legislation, regulatory proposals, and healthcare payor initiatives that may increase our costs of compliance and adversely affect our or our partners’ ability to market our products, develop our product candidates, obtain collaborators, and raise capital.
If we fail to adequately protect or enforce our intellectual property rights, the value of those rights would diminish. Legal proceedings to protect or enforce our patents, the patents of our partners, or our other intellectual property rights could be expensive, time consuming, and unsuccessful. If we fail to secure the rights to patents of others, this could adversely affect our business.
We face an inherent risk of liability in the event that the use or misuse of our products or product candidates results in personal injury or death, and our product liability insurance coverage may be insufficient.
If we fail to reach milestones or to make annual minimum payments or otherwise breach our obligations under our license agreements, our licensors may terminate our agreements with them and/or seek additional remedies.
The Pharmakon Loan Agreement contains conditions and restrictions that limit our flexibility in operating our business. We may be required to make a prepayment or repay our outstanding indebtedness under the Pharmakon Loan Agreement earlier than we expect if a prepayment event or an event of default occurs, including a material adverse change with respect to us, which could have a material adverse effect on our business.
International expansion of our business exposes us to business, legal, regulatory, political, operational, financial, and economic risks. For example, our actual or perceived failure to comply with European governmental laws and regulations and other obligations related to privacy, data protection, and information security could harm our business. In addition, the United Kingdom’s withdrawal from the European Union could result in increased regulatory and legal complexity, which may make it more difficult for us to do business in Europe and impose additional challenges in securing regulatory approval of our product candidates in Europe.
If our facilities incur damage or power is lost for a significant length of time, our business will suffer.
A significant disruption in our or our third-party vendors’ information technology systems or a cybersecurity breach could adversely affect our business.
Our existing principal stockholders hold a substantial amount of our common stock and may be able to influence significant corporate decisions, which may conflict with the interests of other stockholders.
Our stock price has been, and is likely to continue to be, highly volatile, which could cause the value of an investment in our common stock to decline significantly.
Natural disasters, epidemic or pandemic disease outbreaks, trade wars, armed conflicts, political unrest, or other events could disrupt our business or operations or those of our development partners, manufacturers, regulators, or third parties with whom we conduct business now or in the future.
Our business, operations, clinical development or commercialization plans and timelines, and access to capital could be adversely affected by unpredictable and unstable market and economic conditions.
We are subject to legal proceedings, which could harm our reputation or result in other losses or unexpected expenditure of time and resources.
iii

If we fail to retain our existing key personnel or fail to attract and retain additional key personnel, the development of our product candidates, the commercialization of our products, and the related expansion of our business will be delayed or stopped.

BIOCRYST PHARMACEUTICALS, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(In thousands, except per share amounts)
(Unaudited)
Note 1 Significant Accounting Policies and Concentrations of Risk
The Company
BioCryst Pharmaceuticals, Inc. (the “Company”) is a commercial-stage biotechnology company that discovers and commercializes novel, oral, small-molecule medicines. The Company focuses on oral treatments for rare diseases in which significant unmet medical needs exist and an enzyme plays the key role in the biological pathway of the disease. The Company was founded in 1986 and incorporated in Delaware in 1991, and its headquarters is located in Durham, North Carolina. The Company integrates the disciplines of biology, crystallography, medicinal chemistry and computer modeling to discover and develop small molecule pharmaceuticals through the process known as structure-guided drug design.
The Company’s marketed products include oral, once-daily ORLADEYO® for the prevention of hereditary angioedema (“HAE”) attacks and RAPIVAB® (peramivir injection) for the treatment of acute uncomplicated influenza in the United States. ORLADEYO received regulatory approval in the United States in December 2020. ORLADEYO has also received regulatory approvals in multiple global markets. The Company is commercializing ORLADEYO in each of these territories directly or through distributors, except in Japan where Torii Pharmaceutical Co., Ltd. (“Torii”), the Company’s collaborative partner, has the exclusive right to commercialize ORLADEYO for the prevention of HAE attacks in exchange for certain milestone and royalty payments to the Company. In addition to its approval in the United States, peramivir injection has received regulatory approvals in Canada, Australia, Japan, Taiwan and Korea.
Based on the Company’s expectations for revenue and operating expenses, the Company believes its financial resources available at June 30, 2023 will be sufficient to fund its operations for at least the next 12 months. The Company has sustained operating losses for the majority of its corporate history and expects that its 2023 expenses will exceed its 2023 revenues. The Company expects to continue to incur operating losses and negative cash flows until revenues reach a level sufficient to support ongoing operations. The Company’s liquidity needs will largely be determined by the success of operations in regard to the successful commercialization of its products and the progression of its product candidates in the future. The Company regularly evaluates other opportunities to fund future operations, including: (1) out-licensing rights to certain of its products or product candidates, pursuant to which the Company would receive cash milestone payments; (2) raising additional capital through equity or debt financings or from other sources, including royalty or other monetization transactions; (3) obtaining additional product candidate regulatory approvals, which would generate revenue, milestone payments and cash flow; (4) reducing spending on one or more research and development programs, including by discontinuing development; (5) restructuring operations to change its overhead structure; and/or (6) securing U.S. Government funding of its programs, including obtaining procurement contracts. The Company may issue securities, including common stock, preferred stock, depositary shares, purchase contracts, warrants, debt securities and units, through private placement transactions or registered public offerings in the future. The Company’s future liquidity needs, and ability to address those needs, will largely be determined by the success of its products and product candidates; the timing, scope and magnitude of its research and development and commercial expenses; and key developments and regulatory events and its decisions in the future.
Basis of Presentation
The consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany transactions and balances among the consolidated entities have been eliminated from the consolidated financial statements.
The Company’s consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial reporting and the instructions to Form 10-Q and do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. Such financial statements reflect all adjustments that are, in management’s opinion, necessary to present fairly, in all material respects, the Company’s consolidated financial position, results of operations, and cash flows. There were no adjustments other than normal recurring adjustments.

The Company has made certain presentation changes relative to its revenue, which management considers fundamental to understanding the Company’s current business and financial performance related to its primary product,
5

ORLADEYO, including expanded international sales of ORLADEYO, relative to the Company’s other sources of revenue. Accordingly, certain disaggregated revenue information has been provided in this Note 1 and “Note 2—Revenue” to these consolidated financial statements. These presentation changes have been applied to prior year revenue amounts for consistency and comparability.
These financial statements should be read in conjunction with the financial statements for the year ended December 31, 2022 and the notes thereto included in the Company’s 2022 Annual Report on Form 10-K. Interim operating results are not necessarily indicative of operating results for the full year. The balance sheet as of December 31, 2022 has been derived from the audited consolidated financial statements included in the Company’s most recent Annual Report on Form 10-K.
Use of Estimates
The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. Significant estimates in the Company’s consolidated financial statements have been made relative to the calculation of net product sales, the ORLADEYO and Factor D inhibitors royalty financing obligations, inventory reserves, certain accruals, primarily related to the Company’s research and development expenses, the valuation of stock options and the valuation allowance for deferred tax assets resulting from net operating losses. These estimates are based on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ from those estimates.
Revenue Recognition
The Company recorded the following revenues for the three and six months ended June 30, 2023 and 2022:
Three Months Ended June 30,Six Months Ended June 30,
2023202220232022
Product sales, net$80,504 $64,888 $148,670 $114,434 
Collaborative and other revenues1,987 644 2,599 1,021 
Total revenues$82,491 $65,532 $151,269 $115,455 
Pursuant to Accounting Standards Codification (“ASC”) Topic 606, the Company recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve this core principle, Topic 606 includes provisions within a five step model that includes (i) identifying the contract with a customer, (ii) identifying the performance obligations in the contract, (iii) determining the transaction price, (iv) allocating the transaction price to the performance obligations, and (v) recognizing revenue when, or as, an entity satisfies a performance obligation.
At contract inception, the Company identifies the goods or services promised within each contract, assesses whether each promised good or service is distinct, and determines those that are performance obligations. The Company recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when the performance obligation is satisfied.
Product Sales, Net
The Company’s principal sources of product sales are sales of ORLADEYO, which the Company began shipping to patients in December 2020, sales of peramivir to the Company’s licensing partners and sales of RAPIVAB to the U.S. Department of Health and Human Services (“HHS”) under the Company’s procurement contract. In the United States, the Company ships ORLADEYO directly to patients through a single specialty pharmacy, which is considered its customer. In the European Union, United Kingdom and elsewhere, the Company sells ORLADEYO to specialty distributors as well as hospitals and pharmacies, which collectively are considered its customers.
The Company recognizes revenue for sales when its customers obtain control of the product, which generally occurs upon delivery. For ORLADEYO, the Company classifies payments to its specialty pharmacy customer for certain services provided by its customer as selling, general and administrative expenses to the extent such services provided are determined to be distinct from the sale of its product.
6

Net revenue from sales of ORLADEYO is recorded at net selling price (transaction price), which includes estimates of variable consideration for which reserves are established for (i) estimated government rebates, such as Medicaid and Medicare Part D reimbursements, and estimated managed care rebates, (ii) estimated chargebacks, (iii) estimated costs of co-payment assistance programs and (iv) product returns. These reserves are based on the amounts earned or to be claimed on the related sales and are classified as reductions of accounts receivable or as a current liability. Overall, these reserves reflect the Company’s best estimates of the amount of consideration to which it is entitled based on the terms of the applicable contract. The amount of variable consideration included in the transaction price may be constrained and is included in the net sales price only to the extent that it is probable that a significant reversal in the amount of the cumulative revenue recognized will not occur in a future period. Actual amounts of consideration ultimately received may differ from the Company’s estimates. If actual results in the future vary from estimates, the Company adjusts these estimates, which would affect net product revenue and earnings in the period such variances become known.
Government and Managed Care Rebates. The Company contracts with government agencies and managed care organizations or, collectively, third-party payors, so that ORLADEYO will be eligible for purchase by, or partial or full reimbursement from, such third-party payors. The Company estimates the rebates it will provide to third-party payors and deducts these estimated amounts from total gross product revenues at the time the revenues are recognized. These reserves are recorded in the same period in which the revenue is recognized, resulting in a reduction of product revenue and the establishment of a current liability. The Company estimates the rebates that it will provide to third-party payors based upon (i) the Company’s contracts with these third-party payors, (ii) the government mandated discounts applicable to government-funded programs, (iii) a range of possible outcomes that are probability-weighted for the estimated payor mix, and (iv) product distribution information obtained from the Company’s specialty pharmacy.
Chargebacks. Chargebacks are discounts that occur when certain contracted customers, pharmacy benefit managers, insurance companies, and government programs purchase directly from the Company’s specialty pharmacy. These customers purchase the Company’s products under contracts negotiated between them and the Company’s specialty pharmacy. The specialty pharmacy, in turn, charges back to the Company the difference between the price the specialty pharmacy paid and the negotiated price paid by the contracted customers, which may be higher or lower than the specialty pharmacy’s purchase price from the Company. The Company estimates chargebacks and adjusts gross product revenues and accounts receivable based on the estimates at the time revenues are recognized.
Co-payment assistance and patient assistance programs. Patients who have commercial insurance and meet certain eligibility requirements may receive co-payment assistance. Based upon the terms of the program and co-payment assistance utilization reports received from the specialty pharmacy, the Company is able to estimate the co-payment assistance amounts, which are recorded in the same period in which the related revenue is recognized, resulting in a reduction of product revenue. The Company also offers a patient assistance program that provides free drug product, for a limited period of time, to allow a patient’s insurance coverage to be established. Based on patient assistance program utilization reports provided by the specialty pharmacy, the Company records gross revenue of the product provided and a full reduction of the revenue amount for the free drug discount.
Product returns. The Company does not provide contractual return rights to its customers, except in instances where the product is damaged or defective. Non-acceptance by the patient of shipped drug product by the specialty pharmacy is reflected as a reversal of sales in the period in which the sales were originally recorded. Reserves for estimated non-acceptances by patients are recorded as a reduction of revenue in the period that the related revenue is recognized, as well as a reduction to accounts receivable. Estimates of non-acceptance are based on quantitative information provided by the specialty pharmacy.
Collaborative and Other Revenues
The Company has collaboration and license agreements with a number of third parties, as well as research and development agreements with certain government entities. The Company’s primary sources of revenue from these collaborative and other research and development arrangements are license, service and royalty revenues.
Revenue from license fees, royalty payments, milestone payments, and research and development fees are recognized as revenue when the earnings process is complete and the Company has no further continuing performance obligations or the Company has completed the performance obligations under the terms of the agreement.
Arrangements that involve the delivery of more than one performance obligation are initially evaluated as to whether the intellectual property licenses granted by the Company represent distinct performance obligations. If they are determined to be distinct, the value of the intellectual property licenses would be recognized up-front while the research and development service fees would be recognized as the performance obligations are satisfied. For performance obligations
7

based on services performed, the Company measures progress using an input method based on the effort it expends or costs it incurs toward the satisfaction of the performance obligation in relation to the total estimated effort or costs. Variable consideration is assessed at each reporting period as to whether it is not subject to significant future reversal and, therefore, should be included in the transaction price at the inception of the contract. If a contract includes a fixed or minimum amount of research and development support, this also would be included in the transaction price. Changes to collaborations, such as the extensions of the research term or increasing the number of targets or technology covered under an existing agreement, are assessed for whether they represent a modification or should be accounted for as a new contract. For contracts with multiple performance obligations, revenue is allocated to each performance obligation based on its relative standalone selling price. Standalone selling prices are based on observable prices at which the Company separately sells the products or services. If a standalone selling price is not directly observable, then the Company estimates the standalone selling price using either an adjusted market assessment approach or an expected cost plus margin approach, representing the amount that the Company believes the market is willing to pay for the product or service. Analyzing the arrangement to identify performance obligations requires the use of judgment, and each may be an obligation to deliver services, a right or license to use an asset, or another performance obligation.
Milestone payments are recognized as licensing revenue upon the achievement of specified milestones if (i) the milestone is substantive in nature and the achievement of the milestone was not probable at the inception of the agreement and (ii) the Company has a right to payment. Any milestone payments received prior to satisfying these revenue recognition criteria are recorded as deferred revenue.
Reimbursements received for direct out-of-pocket expenses related to research and development costs are recorded as revenue in the Consolidated Statements of Comprehensive Loss rather than as a reduction in expenses. Under the Company’s contracts with the Biomedical Advanced Research and Development Authority within HHS (“BARDA/HHS”) and the National Institute of Allergy and Infectious Diseases (“NIAID/HHS”), revenue is recognized as reimbursable direct and indirect costs are incurred.
Under certain of the Company’s license agreements, the Company receives royalty payments based upon its licensees’ net sales of covered products. Royalties are recognized at the later of when (i) the subsequent sale or usage occurs, or (ii) the performance obligation to which some or all of the sales-based or usage-based royalty has been satisfied.
Cash and Cash Equivalents
The Company generally considers cash equivalents to be all cash held in commercial checking accounts, certificates of deposit, money market accounts or investments in debt instruments with maturities of three months or less at the time of purchase. The carrying value of cash and cash equivalents approximates fair value due to the short-term nature of these items.
Restricted Cash
Total restricted cash was $1,574 and $1,472 as of June 30, 2023 and December 31, 2022, respectively, and primarily consisted of $1,457 and $1,449 as of June 30, 2023 and December 31, 2022, respectively, for a letter of credit the Company is required to maintain associated with the lease execution and build-out of its Birmingham research facilities.
Investments
The Company invests in high credit quality investments in accordance with its investment policy, which is designed to minimize the possibility of loss. The objective of the Company’s investment policy is to ensure the safety and preservation of invested funds, as well as maintaining liquidity sufficient to meet cash flow requirements. The Company places its excess cash with high credit quality financial institutions, commercial companies, and government agencies in order to limit the amount of its credit exposure. In accordance with its policy, the Company is able to invest in marketable debt securities that may consist of U.S. Government and government agency securities, money market and mutual fund investments, certificates of deposits, municipal and corporate notes and bonds, and commercial paper, among others. The Company’s investment policy requires it to purchase high-quality marketable securities with a maximum individual maturity of three years and requires an average portfolio maturity of no more than 12 months. Some of the securities in which the Company invests may have market risk. This means that a change in prevailing interest rates may cause the principal amount of the investment to fluctuate. To minimize this risk, the Company schedules its investments with maturities that coincide with expected cash flow needs, thus avoiding the need to redeem an investment prior to its maturity date. Accordingly, the Company does not believe it has a material exposure to interest rate risk arising from its investments. Generally, the Company’s investments are not collateralized. The Company has not realized any significant losses from its investments.
8

The Company classifies all of its investments as available-for-sale. Unrealized gains and losses on investments are recognized in comprehensive loss, unless an unrealized loss is considered to be other than temporary, in which case the unrealized loss is charged to operations. The Company periodically reviews its investments for other than temporary declines in fair value below cost basis and whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The Company believes the individual unrealized losses represent temporary declines primarily resulting from interest rate changes. Realized gains and losses are reflected in interest and other income in the Consolidated Statements of Comprehensive Loss and are determined using the specific identification method with transactions recorded on a settlement date basis. Investments with original maturities at date of purchase beyond three months and which mature at or less than 12 months from the balance sheet date are classified as current. Investments with a maturity beyond 12 months from the balance sheet date are classified as long-term. At June 30, 2023, the Company believes that the cost of its investments is recoverable in all material respects.
Trade Receivables
The majority of the Company’s trade receivables arise from product sales and primarily represent amounts due from its specialty pharmacy customer in the United States and other third-party distributors, hospitals and pharmacies in the European Union, United Kingdom and elsewhere and have standard payment terms that generally require payment within 30 to 90 days.
Receivables from collaborations are recorded for amounts due to the Company related to reimbursable research and development costs from HHS, and royalty receivables from the Company’s partners, including Shionogi & Co., Ltd. (“Shionogi”), Green Cross, and Torii.
Monthly invoices are submitted to HHS related to reimbursable research and development costs. The Company is also entitled to monthly reimbursement of indirect costs based on rates stipulated in the underlying contract. The Company’s calculations of its indirect cost rates are subject to audit by the U.S. Government.
The Company does not adjust its receivables for the effects of a significant financing component at contract inception if it expects to collect the receivables in one year or less from the time of sale.
The Company provides reserves against trade receivables for estimated losses that may result from a customer's inability to pay. Receivables are evaluated to determine if any reserve or allowance should be recorded based on consideration of the current economic environment, expectations of future economic conditions, specific circumstances and the Company’s own historical collection experience. Amounts determined to be uncollectible are charged or written-off against the reserve.
Inventory
The Company’s inventories primarily relate to ORLADEYO. Additionally, the Company’s inventories include RAPIVAB and peramivir.
The Company values its inventories at the lower of cost or estimated net realizable value. The Company determines the cost of its inventories, which includes amounts related to materials, labor, manufacturing overhead and shipping and handling costs on a first-in, first-out (FIFO) basis. Raw materials and work-in-process include all inventory costs prior to packaging and labeling, including raw material, active product ingredient, and the drug product. Finished goods include packaged and labeled products.
The Company’s inventories are subject to expiration dating. The Company regularly evaluates the carrying value of its inventories and provides valuation reserves for any estimated obsolete, short-dated or unmarketable inventories. In addition, the Company may experience spoilage of its raw materials and supplies. The Company’s determination that a valuation reserve might be required, in addition to the quantification of such reserve, requires it to utilize significant judgment. During the six months ended June 30, 2023, the Company evaluated its inventory levels and associated expiration dating relative to the latest sales forecasts for ORLADEYO and RAPIVAB and estimated those inventories at risk of obsolescence. Accordingly, the Company recorded an increase to the inventory valuation reserve of $238 for a total reserve of $1,415 as of June 30, 2023.
The Company expenses costs related to the production of inventories as research and development expenses in the period incurred until such time it is believed that future economic benefit is expected to be recognized, which generally is upon receipt of regulatory approval. Upon regulatory approval, the Company capitalizes subsequent costs related to the production of inventories.

Property and Equipment
Property and equipment are recorded at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the assets. Computer equipment is depreciated over a life of three years. Laboratory equipment, office equipment, and software are depreciated over a life of five years. Furniture and fixtures are depreciated over a life of seven years. Leasehold improvements are amortized over their estimated useful lives or the expected lease term, whichever is less.
In accordance with U.S. GAAP, the Company periodically reviews its property and equipment for impairment when events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Determination of recoverability is based on an estimate of undiscounted future cash flows resulting from the use of the asset and its eventual disposition. In the event that such cash flows are not expected to be sufficient to recover the carrying amount of the assets, the assets are written down to their estimated fair values. Property and equipment to be disposed of are reported at the lower of carrying amount or fair value less cost to sell.
Accrued Expenses
The Company enters into contractual agreements with third-party vendors who provide research and development, manufacturing, distribution, and other services in the ordinary course of business. Some of these contracts are subject to milestone-based invoicing, and services are completed over an extended period of time. The Company records liabilities under these contractual commitments when it determines an obligation has been incurred, regardless of the timing of the invoice. This process involves reviewing open contracts and purchase orders, communicating with applicable Company personnel to identify services that have been performed on its behalf and estimating the level of service performed and the associated cost incurred for the service when the Company has not yet been invoiced or otherwise notified of actual cost. The majority of service providers invoice the Company monthly in arrears for services performed. The Company makes estimates of accrued expenses as of each balance sheet date in its financial statements based on the facts and circumstances, which can include assumptions such as expected patient enrollment, site activation and estimated project duration. The Company periodically confirms the accuracy of its estimates with the service providers and makes adjustments if necessary. Examples of estimated accrued expenses include (i) fees paid to clinical research organizations (“CROs”) in connection with preclinical and toxicology studies and clinical trials; (ii) fees paid to investigative sites in connection with clinical trials; (iii) fees paid to contract manufacturers in connection with the production of the Company’s raw materials, drug substance, drug products, and product candidates; and (iv) professional fees.
The Company bases its expenses related to clinical trials on its estimates of the services received and efforts expended pursuant to contracts with multiple research institutions and CROs that conduct and manage clinical trials on the Company’s behalf. The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven payment flows. Payments under some of these contracts depend on factors such as the successful enrollment of patients and the completion of clinical trial milestones. In accruing service fees, the Company estimates the time period over which services will be performed and the level of effort expended in each period. If the actual timing of the performance of services or the level of effort varies from the estimate, the Company will adjust the accrual accordingly. If the Company does not identify costs that it has begun to incur or if it underestimates or overestimates the level of these costs, actual expenses could differ from such estimates. As of June 30, 2023 and December 31, 2022, the carrying value of accrued expenses approximates their fair value due to their short-term settlement.
Cost of Product Sales
Cost of product sales includes the cost of producing and distributing inventories that are related to product revenue during the respective period, including freight. In addition, shipping and handling costs for product shipments are recorded as incurred. Finally, cost of product sales may also include costs related to excess or obsolete inventory adjustment charges.
Research and Development Expenses
The Company’s research and development costs are charged to expense when incurred. Research and development expenses include all direct and indirect development costs related to the development of the Company’s portfolio of product candidates. Advance payments for goods or services that will be used or rendered for future research and development activities are deferred and capitalized. Such amounts are recognized as expense when the related goods are delivered or the related services are performed. Research and development expenses include, among other items, personnel costs, including salaries and benefits, manufacturing costs, clinical, regulatory, and toxicology services performed by CROs, materials and supplies, and overhead allocations consisting of various administrative and facilities related costs, as well as termination fees and other commitments associated with discontinued programs. Most of the Company’s
10

manufacturing and clinical and preclinical studies are performed by third-party CROs. Costs for studies performed by CROs are accrued by the Company over the service periods specified in the contracts, and estimates are adjusted, if required, based upon the Company’s ongoing review of the level of services actually performed.
Additionally, the Company has license agreements with third parties which require fees related to sublicense agreements or maintenance fees. The Company expenses sublicense payments as incurred unless they are related to revenues that have been deferred, in which case the expenses are deferred and recognized over the related revenue recognition period. The Company expenses maintenance payments as incurred.
Deferred collaboration expenses represent sublicense payments paid to the Company’s academic partners upon receipt of consideration from various commercial partners, and other consideration paid to the Company’s academic partners for modification to existing license agreements. These deferred expenses would not have been incurred without receipt of such payments or modifications from the Company’s commercial partners and are being expensed in proportion to the related revenue being recognized. The Company believes that this accounting treatment appropriately matches expenses with the associated revenue.
The Company groups its research and development expenses into two major categories: direct expenses and indirect expenses. Direct expenses consist of compensation for research and development personnel and costs of outside parties to conduct laboratory studies, develop manufacturing processes and manufacture the product candidate, conduct and manage clinical trials, as well as other costs related to the Company’s clinical and preclinical studies. Additionally, direct expenses consist of those costs necessary to discontinue and close out a development program, including termination fees and other commitments. These costs are accumulated and tracked by active program. Indirect expenses consist of lab supplies and services, facility expenses, depreciation of development equipment and other overhead of the Company’s research and development efforts. These costs apply to work on non-active product candidates and the Company’s discovery research efforts.
Selling, General and Administrative Expenses
Selling, general and administrative expense is primarily comprised of compensation and benefits associated with sales and marketing, finance, human resources, legal, information technology and other administrative personnel. Additionally, selling, general and administrative expenses are comprised of market research, marketing, advertising and legal expenses, including patent costs, licenses and other general and administrative costs.
Advertising expenses related to ORLADEYO were $3,290 and $4,095 for the three months ended June 30, 2023, and 2022, respectively, and $7,337 and $8,079 for the six months ended June 30, 2023, and 2022, respectively.
All patent related costs are expensed to selling, general and administrative expenses when incurred as recoverability of such expenditures is uncertain.
Leases
The Company leases certain assets, predominantly under operating leases, which consist of real estate leases, laboratory equipment leases and office equipment leases as of June 30, 2023. The Company accounts for lease obligations in accordance with ASU 2016-02: Leases (Topic 842), which requires a lessee to recognize a right-of-use asset and a lease liability on its balance sheet for most leases.
Certain of the Company’s operating leases provide for renewal options, which can vary by lease. The right-of-use asset and lease liabilities on the Company’s Consolidated Balance Sheets represent payments over the lease term, which includes renewal options for certain real estate leases that the Company is likely to exercise. As part of the Company’s assessment of the lease term, the Company elected the hindsight practical expedient, which allows companies to use current knowledge and expectations when determining the likelihood to extend lease options. Certain operating leases include rent escalation provisions, which the Company recognizes as expense on a straight-line basis. Lease expense for leases with an initial term of twelve months or less was not material.
The discount rate used in the calculation of the Company’s right-of-use asset and lease liability was determined based on the stated rate within each contract when available, or the Company’s collateralized borrowing rate from lending institutions.
The Company has not made any residual value guarantees related to its leases; therefore, the Company has no corresponding liability recorded on its Consolidated Balance Sheets.
11

Stock-Based Compensation
All share-based payments, including grants of stock option awards and restricted stock unit awards, are recognized in the Company’s Consolidated Statements of Comprehensive Loss based on their fair values. Stock-based compensation cost is estimated at the grant date based on the fair value of the award and is recognized as expense on a straight-line basis over the requisite service period of the award. Determining the appropriate fair value model and the related assumptions for the model requires judgment, including estimating the life of an award, the stock price volatility, and the expected term. The Company utilizes the Black-Scholes option-pricing model to value its stock option awards and recognize compensation expense on a straight-line basis over the vesting periods. The estimation of share-based payment awards that will ultimately vest requires judgment, and to the extent actual results or updated estimates differ from the Company’s current estimates, such amounts will be recorded as a cumulative adjustment in the period estimates are revised. In addition, the Company has outstanding performance-based stock options and restricted stock units for which no compensation expense is recognized until “performance” is deemed to have occurred. Significant management judgment is also required in determining estimates of future stock price volatility and forfeitures to be used in the valuation of the options. Actual results, and future changes in estimates, may differ substantially from the Company’s current estimates.
Interest Expense and Deferred Financing Costs
Interest expense for the three and six months ended June 30, 2023 was $28,915 and $56,311, respectively, and $24,022 and $47,859 for the three and six months ended June 30, 2022, respectively. Interest expense primarily relates to the royalty financing obligations (Note 6) and the secured term loan borrowings under the Athyrium Credit Agreement during 2022 and the term loan borrowings under both the Athyrium Credit Agreement and the Pharmakon Loan Agreement during 2023 (Note 7). On April 17, 2023, the Company entered into the Pharmakon Loan Agreement and received initial funding in the form of a term loan of $300,000, the proceeds of which were primarily used to repay the term loan borrowings under the Athyrium Credit Agreement. Accordingly, interest expense for both the three and six months ended June 30, 2023 includes interest expense from both the Athyrium Credit Agreement and the Pharmakon Loan Agreement. Costs directly associated with the borrowings have been capitalized and are netted against the corresponding debt liabilities on the Consolidated Balance Sheets. These costs are being amortized to interest expense over the terms of the corresponding borrowings using the effective interest rate method. Amortization of deferred financing costs included in interest expense was $408 and $1,306 for the three and six months ended June 30, 2023, respectively, and $(172) and $(339) for the three and six months ended June 30, 2022, respectively. When utilizing the effective interest method, in periods in which PIK interest was designated and was added to the outstanding principal balance of the borrowing, the amortization of the deferred debt fees and issuance costs was accretive. The quarter ended December 31, 2022 was the last period eligible for the PIK Interest Payment designation under the Athyrium Credit Agreement.
Interest Expense and Royalty Financing Obligations
The royalty financing obligations are eligible to be repaid based on royalties from net sales of ORLADEYO and BCX10013. Interest expense is accrued using the effective interest rate method over the estimated period each of the related liabilities will be paid. This requires the Company to estimate the total amount of future royalty payments to be generated from product sales over the life of the agreement. The Company imputes interest on the carrying value of each of the royalty financing obligations and records interest expense using an imputed effective interest rate. The Company reassesses the expected royalty payments each reporting period and accounts for any changes through an adjustment to the effective interest rate on a prospective basis. The assumptions used in determining the expected repayment term of the debt and amortization period of the issuance costs require that the Company make estimates that could impact the carrying value of each of the liabilities, as well as the periods over which associated issuance costs will be amortized. A significant increase or decrease in forecasted net sales could materially impact each of the liability balances, interest expense and the time periods for repayment.
Income Taxes
The liability method is used in the Company’s accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based on differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that are expected to be in effect when the differences are expected to reverse.
The Company accounts for uncertain tax positions in accordance with U.S. GAAP. Significant management judgment is required in determining the Company’s provision for income taxes, deferred tax assets and liabilities and any valuation allowance recorded against net deferred tax assets. The Company has recorded a valuation allowance against substantially all potential tax assets, due to uncertainties in its ability to utilize deferred tax assets, primarily consisting of certain net operating losses carried forward, before they expire. The valuation allowance is based on estimates of taxable
12

income in each of the jurisdictions in which the Company operates and the period over which its deferred tax assets will be recoverable.
Beginning in fiscal year 2021, the Company began accruing for U.S. state taxes and foreign income taxes as a result of increased nexus in both U.S. state and foreign jurisdictions where historically the Company had no presence.
In addition, starting in 2022, amendments to Section 174 of the Internal Revenue Code of 1986, as amended (“IRC”), no longer permit an immediate deduction for research and development expenditures in the tax year that such costs are incurred. Instead, these IRC Section 174 development costs must now be capitalized and amortized over either a five- or 15-year period, depending on the location of the activities performed. The new amortization period begins with the midpoint of any taxable year that IRC Section 174 costs are first incurred, regardless of whether the expenditures were made prior to or after July 1, and runs until the midpoint of year five for activities conducted in the United States or year 15 in the case of development conducted on foreign soil.
Net Loss Per Share
Net loss per share is based upon the weighted average number of common shares outstanding during the period. Diluted loss per share is equivalent to basic net loss per share for all periods presented herein because common equivalent shares from unexercised stock options, warrants and common shares expected to be issued under the Company’s equity compensation plans were anti-dilutive. The calculation of diluted earnings per share does not include 19,770 and 20,948 shares of potential common stock for the three and six months ended June 30, 2023, respectively, and 23,090 and 25,877 shares of potential common stock for the three and six months ended June 30, 2022, respectively, as their impact would be anti-dilutive.
Accumulated Other Comprehensive Income
Accumulated other comprehensive income is comprised of cumulative foreign currency translation adjustments and unrealized gains and losses on available-for-sale investments and is disclosed as a separate component of stockholders’ equity. Realized gain and loss amounts on available-for-sale investments are reclassified from accumulated other comprehensive income and recorded as interest and other income on the Consolidated Statements of Comprehensive Loss. There were no realized gains or losses reclassified out of accumulated other comprehensive income for the six months ended June 30, 2023 and 2022.
Significant Customers and Other Risks
Significant Customers
The Company’s primary sources of revenue and cash flow are the sales of ORLADEYO in the United States and other global markets and, for 2022, sales of RAPIVAB (peramivir injection) under the Company’s procurement contract with the Assistant Secretary for Preparedness and Response within HHS.
ORLADEYO is distributed through an arrangement with a single specialty pharmacy in the United States, which represents the substantial majority of the ORLADEYO net product sales. The specialty pharmacy subsequently sells ORLADEYO to its customers (pharmacy benefit managers, insurance companies, government programs and group purchasing organizations) and dispenses product to patients. The specialty pharmacy’s inability or unwillingness to continue these distribution activities could adversely impact the Company’s business, results of operations and financial condition.
The Company is distributing ORLADEYO in other global markets directly or through distributors, except in Japan where Torii, the Company’s collaborative partner, has the exclusive right to commercialize ORLADEYO.
Further, the Company’s drug development activities are performed by a limited group of third-party vendors. If any of these vendors were unable to perform its services, this could significantly impact the Company’s ability to complete its drug development activities.
Risks from Third-Party Manufacturing and Distribution Concentration
The Company relies on a single source manufacturer for active pharmaceutical ingredient and finished drug product manufacturing of product candidates in development and on a single specialty pharmacy for distribution of approved drug product in the United States. Delays or disruption in the manufacture or distribution of any product could adversely impact the future procurement stockpiling of the Company’s commercial product, commercial revenue and product candidates.
13

Credit Risk
Cash equivalents and investments are financial instruments that potentially subject the Company to concentration of risk to the extent recorded on the Consolidated Balance Sheets. The Company deposits excess cash with major financial institutions in the United States. Balances may exceed the amount of insurance provided on such deposits. The Company believes it has established guidelines for investment of its excess cash relative to diversification and maturities that maintain safety and liquidity. To minimize the exposure due to adverse shifts in interest rates, the Company maintains a portfolio of investments with an average maturity of approximately 12 months or less.
The Company’s receivables from sales of ORLADEYO are primarily due from one customer, resulting in a concentration of credit risk. Sales of ORLADEYO from the Company to the specialty pharmacy only occur once an order of product has been received by the specialty pharmacy from one of its customers, which include pharmacy benefit managers, insurance companies, government programs and group purchasing organizations.
The majority of the Company’s receivables from collaborations are due from the U.S. Government, for which there is no assumed credit risk.
Recently Adopted Accounting Pronouncements
There have been no new accounting pronouncements adopted by the Company or new accounting pronouncements issued by the Financial Accounting Standards Board during the six months ended June 30, 2023, as compared to the recent accounting pronouncements described in Note 1 of the Company’s Annual Report on Form 10-K for the year ended December 31, 2022, that the Company believes are of significance or potential significance to the Company.
Note 2 Revenue
The Company recorded the following revenues (in thousands):

ORLADEYO revenues represent total revenues from product sales, collaborative revenues and royalties. Other revenues primarily relate to the Company’s galidesivir development contracts with BARDA/HHS and NIAID/HHS and product sales and royalties for peramivir injection (RAPIVAB/RAPIACTA/PERAMIFLU).

Note 3 Investments
The following tables summarize the fair value of the Company’s investments by type. The estimated fair values of the Company’s fixed income investments are classified as Level 2 in the fair value hierarchy as defined in U.S. GAAP. These valuations are based on observable direct and indirect inputs, primarily quoted prices of similar, but not identical,
14

instruments in active markets or quoted prices for identical or similar instruments in markets that are not active. These fair values are obtained from independent pricing services which utilize Level 2 inputs.

See “Note 7—Debt” for further details on the Athyrium Credit Agreement and the Pharmakon Loan Agreement. The restrictions under the Royalty Purchase Agreements on the ability of the Company or any of its subsidiaries to incur indebtedness are eliminated after the achievement of certain specified milestones in the Royalty Purchase Agreements.

The cash consideration obtained pursuant to the Royalty Purchase Agreements is recorded in “Royalty financing obligations” on the Company’s Consolidated Balance Sheets. The fair value for the royalty financing obligations at the time of the transactions was based on the Company’s estimates of future royalties expected to be paid to the counterparty over the life of the arrangement. The Company subsequently records the obligations at its carrying value using the effective interest method. In order to amortize the royalty financing obligations, the Company utilizes the prospective method to estimate the future royalties to be paid by the Company to the counterparty over the life of the arrangement. Under the prospective method, a new effective interest rate is determined based on the revised estimate of remaining cash flows. The new rate is the discount rate that equates the present value of the revised estimate of remaining cash flows with the carrying amount of the debt, and it will be used to recognize interest expense for the remaining periods. The Company periodically assesses the amount and timing of expected royalty payments using a combination of internal projections and forecasts from external sources. The estimates of future net product sales (and resulting royalty payments) are based on key assumptions including population, penetration, probability of success, and sales price, among others. To the extent such payments are greater or less than the Company’s initial estimates or the timing of such payments is materially different than its original estimates, the Company will prospectively adjust the amortization of the royalty financing obligations and the effective interest rate.
During the three months ended June 30, 2023, the Company adjusted its forecasts related to its BCX10013 program and updated its ORLADEYO forecast based on actual results for the first half of 2023. These adjustments impacted the amount and timing of expected royalties to be made under the RPI Royalty Purchase Agreements. As a result, the effective interest rate related to the 2020 RPI Royalty Purchase Agreement decreased from 22.4% to 22.2% and the effective interest rate related to the 2021 RPI Royalty Purchase Agreement decreased from 13.1% to 10.0%. There was no impact to the OMERS Royalty Purchase Agreement, thus the effective interest rate remained at 10.6%.

Concurrent with entering into the 2021 RPI Royalty Purchase Agreement, the Company and RPI entered into a Common Stock Purchase Agreement (the “Common Stock Purchase Agreement”), pursuant to which the Company sold common stock to RPI for a premium of $4,269. This premium has been deferred and is being amortized through interest expense using the effective interest method over the term of the applicable arrangement. See “Note 9—Stockholders’ Equity” for further details on the common stock sale premium.
Note 7 Debt
Pharmakon Loan Agreement
On April 17, 2023, the Company entered into a $450,000 Loan Agreement (the “Pharmakon Loan Agreement”) with BioPharma Credit Investments V (Master) LP and BPCR Limited Partnership, as lenders, and BioPharma Credit PLC, as collateral agent for the lenders. Certain of the Company’s wholly-owned subsidiaries are guarantors to the Pharmakon
18

Loan Agreement. The Pharmakon Loan Agreement provides for an initial term loan in the principal amount of $300,000 (the “Tranche A Loan”) funded on April 17, 2023 (the “Tranche A Closing Date”). The Company used a portion of the proceeds from the Tranche A Loan to repay the $241,787 of outstanding indebtedness (principal and interest due as of April 17, 2023) under the then-existing Athyrium Credit Agreement and pay associated transaction costs and fees, and intends to use the remaining net proceeds of $26,068 for other general corporate purposes.
The Pharmakon Loan Agreement also provides for three additional term loan tranches, at the Company’s option, in principal amounts of $50,000 each (each a “Subsequent Tranche Loan” and, collectively with the Tranche A Loan, the “Pharmakon Term Loans” and each, a “Pharmakon Term Loan”), which may be requested on or prior to September 30, 2024. The maturity date of the Pharmakon Loan Agreement is April 17, 2028 (the “Maturity Date”), the fifth anniversary of the Tranche A Closing Date.
The Pharmakon Loan Agreement provides for quarterly interest-only payments until the Maturity Date, with the unpaid principal amount of the outstanding Pharmakon Term Loans due and payable on the Maturity Date. During the first 18 months following the Tranche A Closing Date, the Company has the option to make a portion of the applicable interest payment on the Tranche A Loan in-kind (a “Pharmakon PIK Interest Payment”) by capitalizing as principal up to 50% of the amount of interest accrued on the Tranche A Loan during the applicable interest period. The Pharmakon Term Loans will bear interest at a rate equal to the three-month Secured Overnight Financing Rate (“SOFR”) rate, which shall be no less than 1.75%, plus 7.00%, per annum or, for each interest period in which a Pharmakon PIK Interest Payment is made, with respect to the Tranche A Loan, SOFR plus 7.25%, per annum.
The Tranche A Loan accrued interest at an effective interest rate of 12.24% for the three months ended June 30, 2023.
The Company is required to make a mandatory prepayment of the Pharmakon Term Loans (i) upon the occurrence of a change of control and (ii) prior to any repayment of any convertible debt that the Company may issue in the future, subject to certain exceptions. The Company may make voluntary prepayments in whole or in part, in minimum $25,000 increments. Prepayments are subject to a prepayment premium equal to, (i) with respect to any prepayment made prior to the second anniversary of the applicable Pharmakon Term Loan borrowing date, the sum of (1) 3.00% of the principal amount of the Pharmakon Term Loan being prepaid plus (2) the aggregate amount of all interest that would have accrued on the principal amount of the Pharmakon Term Loan being prepaid from the date of prepayment through and including the second anniversary of the date of the borrowing of such Pharmakon Term Loan; (ii) with respect to any prepayment made on or after the second anniversary and prior to the third anniversary of the applicable Pharmakon Term Loan borrowing date, 3.00% of the principal amount of the Pharmakon Term Loan being prepaid; (iii) with respect to any prepayment made on or after the third anniversary and prior to the fourth anniversary of the applicable Pharmakon Term Loan, 2.00% of the principal amount of the Pharmakon Term Loan being prepaid; and (iv) with respect to any prepayment made on or after the fourth anniversary of the applicable Pharmakon Term Loan borrowing date and before the Maturity Date, 1.00% of the principal amount of the Pharmakon Term Loan being prepaid. In addition, upon the drawing of any Subsequent Tranche Loan, certain funding fees are required to be paid.
The Pharmakon Loan Agreement also contains representations and warranties and affirmative and negative covenants customary for financings of this type, as well as customary events of default. Certain of the customary negative covenants limit the ability of the Company and certain of its subsidiaries to, among other things, dispose of assets, engage in mergers, acquisitions, and similar transactions, incur additional indebtedness, grant liens, make investments, pay dividends or make distributions or certain other restricted payments in respect of equity, prepay other indebtedness, enter into restrictive agreements, undertake fundamental changes or amend certain material contracts, among other customary covenants, in each case subject to certain exceptions.
A failure to comply with the covenants in the Pharmakon Loan Agreement, or an occurrence of any other event of default, could permit the lenders under the Pharmakon Loan Agreement to declare the borrowings thereunder, together with accrued interest and fees, and any applicable prepayment premium, to be immediately due and payable.
The Company’s obligations under the Pharmakon Loan Agreement are secured by a security interest in, subject to certain exceptions, substantially all of the Company’s assets.
As of June 30, 2023, the Company had total borrowings of $300,000 under the Pharmakon Loan Agreement. Total quarterly interest expense on the Pharmakon Tranche A Loan for the three months ended June 30, 2023 totaled $7,648. As allowable under the Pharmakon Loan Agreement, the Company has designated and accounted for 50% of the quarterly interest payment for the three months ended June 30, 2023 as a Pharmakon PIK Interest Payment and the amount of $3,824 has been added to the outstanding principal balance of the borrowing. The remaining 50% of the quarterly interest payment
19

of $3,824 was paid as of June 30, 2023. As of June 30, 2023, borrowings, including the Pharmakon PIK Interest Payments, totaled $303,824. The fair value of the debt approximates its carrying value based on prevailing interest rates as of the balance sheet date and is considered as Level 2 in the fair value hierarchy.
Incurred debt fees and issuance costs associated with the Tranche A Loan under the Pharmakon Loan Agreement totaled $10,885 and have been deferred and are being amortized as interest expense on an effective interest rate method over the remaining term of the Pharmakon Tranche A Loan. Deferred financing amortization of $237 was recognized for the three and six months ended June 30, 2023.
Athyrium Credit Agreement
On December 7, 2020, the Company entered into a $200,000 Credit Agreement (the “Athyrium Credit Agreement”) with Athyrium Opportunities III Co-Invest 1 LP (“Athyrium”), as lender and as administrative agent for the lenders. Certain of the Company’s direct and indirect subsidiaries were guarantors to the Athyrium Credit Agreement. The Athyrium Credit Agreement provided for an initial term loan in the principal amount of $125,000 (the “Term A Loan”), which was received by the Company on December 7, 2020 and is recorded in “Secured term loan” on the Company’s balance sheet. The Company used a portion of the proceeds from the Term A Loan to repay $43,298 of outstanding indebtedness, including accrued interest, under its prior credit facility with MidCap Financial Trust.
The Athyrium Credit Agreement also provided for two additional term loans, at the Company’s option, in the respective principal amounts of $25,000 (the “Term B Loan”) and $50,000 (the “Term C Loan” and, collectively with the Term A Loan and the Term B Loan, the “Athyrium Term Loans”). Having achieved all required revenue-based milestones, the Company exercised its option to draw upon the additional funding available under the Athyrium Credit Agreement, borrowing the principal amounts of $25,000 under the Term B Loan and $50,000 under the Term C Loan. Both the Term B Loan and the Term C Loan were funded on July 29, 2022 in the aggregate principal amount of $75,000. The Term B Loan and the Term C Loan were subject to all the provisions under the Athyrium Credit Agreement.
On November 19, 2021, the Company entered into an amendment to the Athyrium Credit Agreement to, among other things, (i) permit the Company to enter into the 2021 RPI Royalty Purchase Agreement, the OMERS Royalty Purchase Agreement, and the other definitive documentation related thereto and to perform its obligations thereunder; (ii) require the Company to pay to Athyrium, for the account of the lenders, a make-whole premium plus certain fees set forth in the Athyrium Credit Agreement in the event that the Company prepaid or repaid, or was required to prepay or repay, voluntarily or pursuant to mandatory prepayment obligations under the Athyrium Credit Agreement (e.g., with the proceeds of certain asset sales, certain ORLADEYO out-licensing or royalty monetization transactions (excluding the Royalty Sales), extraordinary receipts, debt issuances, or upon a change of control of the Company and specified other events, subject to certain exceptions), all of the then-outstanding Athyrium Term Loans, in each case, subject to certain exceptions set forth in the Athyrium Credit Agreement.
The Athyrium Credit Agreement provided for quarterly interest-only payments until the maturity date, with the unpaid principal amount of the outstanding Athyrium Term Loans due and payable on the maturity date. For each of the first eight full fiscal quarters following December 7, 2020, the Company had the option to make the applicable interest payment in-kind (an “Athyrium PIK Interest Payment”) by capitalizing the entire amount of interest accrued during the applicable interest period with the unpaid original principal amount outstanding on the last day of such period. The Athyrium Term Loans accrued interest at a rate equal to the three-month LIBOR rate, which was no less than 1.75% and no more than 3.50% (“LIBOR”), plus 8.25%, or for each interest period in which an Athyrium PIK Interest Payment was made, LIBOR plus 10.25%. The quarter ended December 31, 2022 was the last period eligible for the Athyrium PIK Interest Payment designation.
The Athyrium Term Loans accrued interest at an effective interest rate of 11.75% during the period in which the debt was outstanding for the three months ended June 30, 2023 compared to 12.17% for the three months ended June 30, 2022.
Subject to certain exceptions, the Athyrium Credit Agreement would have required the Company to make mandatory prepayments of the Athyrium Term Loans with the proceeds of certain asset sales, certain ORLADEYO out-licensing or royalty monetization transactions (excluding the Royalty Sales), extraordinary receipts, debt issuances, or upon a change of control of the Company and specified other events. The Company could have made voluntary prepayments in whole or in part. Prepayments were subject to a premium equal to, (i) with respect to any voluntary prepayment and certain mandatory prepayments paid on or prior to the second anniversary of the applicable Athyrium Term Loan borrowing date, the amount, if any, by which (a) the sum of (1) 102.00% of the principal amount of the Athyrium Term Loan being prepaid plus (2) the present value of all interest that would have accrued on the principal amount of the Athyrium Term Loan being
20

prepaid through and including the second anniversary of the date of the borrowing of such Athyrium Term Loan, plus 0.50%, exceeds (b) the principal amount of the Athyrium Term Loan being prepaid; (ii) with respect to any prepayment made between the second and third anniversaries of the applicable Athyrium Term Loan borrowing date, 2.00% of the principal amount of the Athyrium Term Loan being prepaid; (iii) with respect to any prepayment made between the third and fourth anniversaries of the applicable Athyrium Term Loan borrowing date, 1.00% of the principal amount of the Athyrium Term Loan being prepaid; and (iv) with respect to any prepayment made after the fourth anniversary of the applicable Athyrium Term Loan borrowing date, 0.00% of the principal amount of the Athyrium Term Loan being prepaid. Upon the prepayment or repayment, including at maturity, of all or any of the Athyrium Term Loans, the Company was obligated to pay an exit fee in an amount equal to 2.00% of the principal amount of the Athyrium Term Loans prepaid or repaid. In addition, each Athyrium Term Loan was subject to a 1.00% commitment fee at its respective borrowing date.
Quarterly interest payments under the Athyrium Credit Agreement for the six months ended June 30, 2023 and 2022 totaled $8,476 and $8,774, respectively. From the Athyrium Term Loan inception through December 31, 2022, the quarterly interest payments were designated and accounted for as Athyrium PIK Interest Payments and added to the outstanding principal balance of the borrowing. The quarter ended December 31, 2022 was the last period eligible for the Athyrium PIK Interest Payment designation. Deferred financing amortization of $1,069 and $(339), was recognized for the six months ended June 30, 2023 and 2022, respectively.
On April 17, 2023, the outstanding principal of the Athyrium Term Loans, including the Athyrium PIK Interest Payments of $240,452 along with interest accrued of $1,335 for the first 17 days of the quarterly interest period ended June 30, 2023, was repaid with the funding received through the Pharmakon Loan Agreement.
Upon repayment of the Athyrium Term Loans, the Company incurred certain unaccrued prepayment and final payment fees to Athyrium of $17,261. Additionally, unamortized deferred financing costs of $11,758 associated with the Athyrium Term Loans were written-off at the time of repayment. Collectively, the prepayment and final payment fees and unamortized deferred financing costs totaled $29,019 and are reflected as a one-time loss on extinguishment of debt on the Consolidated Statements of Comprehensive Loss for the three and six months ended June 30, 2023.

On November 19, 2021, concurrent with the Company entering into the 2021 RPI Royalty Purchase Agreement, the Company and RPI entered into the Common Stock Purchase Agreement, pursuant to which the Company issued 3,846 shares of the Company’s common stock to RPI for an aggregate purchase price of $50,000, at a price of $13.00 per share, calculated based on the 20-day volume weighted average price. The $13.00 per share price represented a premium of $1.11 over the closing price of $11.89 of the Company’s common stock on November 17, 2021, the last trading day prior to the execution of the Common Stock Purchase Agreement. The premium of $4,269 paid by RPI on the purchase of the Company’s common stock has been deferred and is being amortized as a component of interest expense of the 2021 RPI royalty financing obligation.

Note 10 Stock-Based Compensation
As of June 30, 2023, the Company had three stock-based employee compensation plans: the Amended and Restated Stock Incentive Plan (“Incentive Plan”), the Amended and Restated Inducement Equity Incentive Plan (“Inducement Plan”) and the Amended and Restated Employee Stock Purchase Plan (“ESPP”). The Incentive Plan was most recently amended and restated on April 24, 2023 and approved by the Company’s stockholders on June 13, 2023. The Inducement Plan was most recently amended and restated by the Company’s Board of Directors on August 26, 2022. The ESPP was most recently amended and restated by the Company’s Board of Directors on July 7, 2023.
The Company recorded the following stock-based compensation expense (in thousands):
Six Months Ended June 30,

Incentive Plan$21,297 $15,867 
Inducement Plan4,720 2,965 
ESPP831 636 
Stock-based compensation expense$26,848 $19,468 
There was approximately $126,812 of total unrecognized compensation expense related to non-vested stock option and restricted stock unit awards granted by the Company as of June 30, 2023. As of June 30, 2023, the Company expected to recognize that expense as follows: $25,967 during the remainder of 2023, $47,207 in 2024, $34,593 in 2025, $18,582 in 2026 and $463 in 2027. In addition, the Company has outstanding performance-based stock options and restricted stock unit awards for which no compensation expense is recognized until “performance” has occurred and the award vests.
Stock Incentive Plan
The Company grants stock option awards, restricted stock and restricted stock units to its employees, directors, and consultants under the Incentive Plan. Under the Incentive Plan, stock option awards are granted with an exercise price equal to the market price of the Company’s common stock at the date of grant. Stock option awards and restricted stock units granted to employees generally vest 25% each year until fully vested after four years.
In December 2014, the Company issued 1,250 performance-based stock options. These awards vest upon successful completion of specific development milestones. As of June 30, 2023, 85% of these grants have vested.
In January 2022, the Company issued 221 performance-based restricted stock unit awards. 21 of the awards met the performance objectives in 2022 and became eligible for vesting at 50% on the first anniversary of the grant date and 25% on each of the second and third anniversaries of the grant date, until fully vested after three years. The remaining awards were cancelled.
Stock option awards and restricted stock unit awards granted to non-employee directors of the Company generally vest over one year. Stock option awards granted to new non-employee directors when they first join the Company’s Board of Directors generally vest, subject to the terms of the Incentive Plan, in 36 equal monthly installments over a three-year period measured from the grant date. All stock option awards have contractual terms of 10 years. Restricted stock unit awards granted to new non-employee directors when they first join the Company’s Board of Directors generally vest, subject to the terms of the Incentive Plan, in three equal annual installments beginning on the first anniversary of the grant date. The vesting and exercise provisions of all awards granted under the Incentive Plan are subject to acceleration in the event of certain stockholder-approved transactions, or upon the occurrence of a change in control as defined in the Incentive Plan.

For stock option awards granted under the Incentive Plan during the first six months of 2023 and 2022, the fair value was estimated on the date of grant using a Black-Scholes option pricing model and the assumptions noted in the table following the next subsection. The weighted average grant date fair value of these awards granted during the first six months of 2023 and 2022 was $6.40 and $7.78, respectively. The fair value of the stock option awards is amortized to expense over the vesting periods using a straight-line expense attribution method. For restricted stock unit awards granted under the Incentive Plan, the fair value of the awards was determined based on the market value of the Company’s shares on the grant date. The weighted average grant date fair value of these awards granted during the first six months of 2023 and 2022 was $9.18 and $13.25, respectively. The fair value of the restricted stock unit awards is amortized to expense over the vesting periods using a straight-line expense attribution method.
Inducement Equity Incentive Plan
The Company has the ability to grant stock option and restricted stock unit awards to newly-hired employees as inducements material to each employee entering employment with the Company. Awards granted to newly hired employees generally vest 25% each year until fully vested after four years and are subject to the terms and conditions of the Inducement Plan. Each stock option has a term of 10 years. The vesting and exercise provisions of all awards granted under the Inducement Plan are subject to acceleration in the event of certain stockholder-approved transactions, or upon the occurrence of a change in control as defined in the Inducement Plan.

For stock option awards granted under the Inducement Plan during the first six months of 2023 and 2022, the fair value was estimated on the date of grant using a Black-Scholes option pricing model and the assumptions noted in the table below. The weighted average grant date fair value of these awards granted during the first six months of 2023 and 2022 was $6.38 and $10.28, respectively. The fair value of the stock option awards is amortized to expense over the vesting periods using a straight-line expense attribution method. For restricted stock unit awards granted under the Inducement Plan, the fair value of the awards was determined based on the market value of the Company’s shares on the grant date.

The weighted average grant date fair value of these awards granted during the first six months of 2023 and 2022 was $8.84 and $13.88, respectively. The fair value of the restricted stock unit awards is amortized to expense over the vesting periods using a straight-line expense attribution method.
The following table summarizes the key assumptions used by the Company to value the stock option awards granted under all plans during the first six months of 2023 and 2022, respectively. The expected life is based on the average of the assumption that all outstanding stock option awards will be exercised at full vesting and the assumption that all outstanding stock option awards will be exercised at the midpoint of the current date (if already vested) or at full vesting (if not yet vested) and the full contractual term. The expected volatility represents the historical volatility on the Company’s publicly-traded common stock. The Company has assumed no expected dividend yield, as dividends have never been paid to stock or option holders and will not be paid for the foreseeable future. The weighted average risk-free interest rate is the implied yield currently available on zero-coupon government issues with a remaining term equal to the expected term.

Employee Stock Purchase Plan
The Company has reserved a total of 7,975 shares of common stock to be purchased under the ESPP, of which 5,617 shares remain available for purchase as of June 30, 2023. Eligible employees may authorize up to 15% of their salary to purchase common stock at the lower of 85% of the beginning or 85% of the ending price during six-month purchase intervals. No more than three thousand shares may be purchased by any one employee at the six-month purchase dates, and no employee may purchase stock having a fair market value at the commencement date of $25 or more in any one calendar year. During the six months ended June 30, 2023, and 2022, the Company issued 176 and 115 shares under the ESPP, respectively. Compensation expense for shares purchased under the ESPP related to the purchase discount and the “look-back” option were determined using a Black-Scholes option pricing model.
Note 11 Collaborative and Other Relationships
ORLADEYO
Torii Pharmaceutical Co., Ltd.
On November 5, 2019, the Company entered into a Commercialization and License Agreement with Torii (the “Torii Agreement”), granting Torii the exclusive right to commercialize ORLADEYO for the prevention of HAE attacks in Japan.
Under the Torii Agreement, the Company received an upfront, non-refundable payment of $22,000. The Japanese National Health Insurance System’s (“NHI”) approval of the addition of ORLADEYO to the NHI drug price list in April 2021 triggered a $15,000 milestone payment from Torii to the Company, which was received in May 2021.
In addition, under the Torii Agreement, the Company is entitled to receive tiered royalty payments, ranging from 20% to 40% of annual net sales of ORLADEYO in Japan during each calendar year. Torii’s royalty payment obligations are subject to customary reductions in certain circumstances, but may not be reduced by more than 50% of the amount that otherwise would have been payable to the Company in the applicable calendar quarter. Torii’s royalty payment obligations commenced upon the first commercial sale of ORLADEYO in Japan and expire upon the later of (i) the tenth anniversary of the date of first commercial sale of ORLADEYO in Japan, (ii) the expiration of the Company’s patents covering ORLADEYO, and (iii) the expiration of regulatory exclusivity for ORLADEYO in Japan. The Company is responsible for supplying Torii with its required amounts of ORLADEYO. The activities of the parties pursuant to the Torii Agreement are overseen by a joint steering committee, composed of an equal number of representatives from each party to coordinate the development and commercialization of ORLADEYO in Japan. Torii launched ORLADEYO in Japan on April 23, 2021.
25

The Company identified performance obligations related to (i) the license to develop and commercialize ORLADEYO, (ii) regulatory approval support and (iii) reimbursement pricing approval support. These were each determined to be distinct from the other performance obligations. The Company allocated the $22,000 upfront consideration to the identified performance obligations using estimation approaches to determine the standalone selling prices under ASC Topic 606. Specifically, in determining the value related to the license, a valuation approach utilizing risk adjusted discounted cash flow projections was used, and an expected cost plus margin approach was utilized for the other performance obligations.
Peramivir Injection (RAPIVAB, RAPIACTA, PERAMIFLU)
Shionogi & Co., Ltd.
In February 2007, the Company entered into an exclusive license agreement with Shionogi to develop and commercialize peramivir in Japan for the treatment of seasonal and potentially life-threatening human influenza. Under the terms of the agreement, Shionogi obtained rights to injectable formulations of peramivir in Japan. The Company developed peramivir under a license from the University of Alabama at Birmingham (“UAB”) and will owe sublicense payments to UAB on any future milestone payments and/or royalties received by the Company from Shionogi. In October 2008, the Company and Shionogi amended the license agreement to expand the territory covered by the agreement to include Taiwan. Shionogi has commercially launched peramivir under the commercial name RAPIACTA in Japan and Taiwan.
Green Cross Corporation
In June 2006, the Company entered into an agreement with Green Cross to develop and commercialize peramivir in Korea. Under the terms of the agreement, Green Cross is responsible for all development, regulatory, and commercialization costs in Korea and the Company is entitled to share in profits resulting from the sale of peramivir in Korea, including the sale of peramivir to the Korean government for stockpiling purposes. Furthermore, Green Cross will pay the Company a premium over its cost to supply peramivir for development and any future marketing of peramivir products in Korea.
Government Collaborations
The Company has previously entered into contracts with the U.S. Government, including the procurement contract with HHS for up to 50,000 doses of RAPIVAB over a five-year period to supply the Strategic National Stockpile for use in a public health emergency and contracts with NIAID/HHS and BARDA/HHS for the development of galidesivir. As of June 30, 2023, the Company has delivered a total of 49,980 RAPIVAB doses of the 50,000 RAPIVAB doses available under the procurement contract, effectively completing the contract with HHS, and all of the Company’s government funding for galidesivir has expired.

Item 2.    Management’s Discussion and Analysis of Financial Condition and Results of Operations
The following Managements Discussion and Analysis (MD&A) is intended to help the reader understand our results of operations and financial condition. MD&A is provided as a supplement to, and should be read in conjunction with, our unaudited consolidated financial statements and the accompanying notes to the financial statements and other disclosures included in this report (including the Cautionary Note Regarding Forward-Looking Statements at the beginning of this report and the Risk Factors section in Part II, Item 1A of this report).
Overview
We are a commercial-stage biotechnology company that discovers and commercializes novel, oral, small-molecule medicines. We focus on oral treatments for rare diseases in which significant unmet medical needs exist and an enzyme plays the key role in the biological pathway of the disease. We integrate the disciplines of biology, crystallography, medicinal chemistry, and computer modeling to discover and develop small-molecule pharmaceuticals through the process known as structure-guided drug design. In addition to these discovery and development efforts, our business strategy includes the efficient commercialization of these drugs in the United States and certain other regions upon regulatory approval. By focusing on rare disease markets, we believe that we can more effectively control the costs of, and our strategic allocation of financial resources toward, post-approval commercialization.
Products and Product Candidates
ORLADEYO® (berotralstat). ORLADEYO is an oral, once-daily therapy discovered and developed by us for the prevention of hereditary angioedema (“HAE”) attacks. ORLADEYO is approved in the United States and multiple global markets for the prevention of HAE attacks in adults and pediatric patients 12 years and older.
We have built out our U.S. commercial infrastructure to support the launch and continued commercialization of ORLADEYO in the United States and are continuing to build our commercial infrastructure to support launches in other markets. Based on proprietary analyses of HAE prevalence and market research studies with HAE patients, physicians, and payors in the United States and Europe, and more than two and a half years of commercialization experience with ORLADEYO, we anticipate the global commercial market for ORLADEYO has the potential to reach a global peak of $1 billion in annual net ORLADEYO revenues. We expect at least 70 to 80 percent of our revenue at peak to come from the United States. These expectations are subject to numerous risks and uncertainties that may cause our actual results, performance, or achievements to be materially different. There can be no assurance that our commercialization methods and strategies will succeed, or that the market for ORLADEYO will develop in line with our current expectations. See “Risk Factors—Risks Relating to Our Business—Risks Relating to Drug Development and Commercialization—There can be no assurance that our or our partners’ commercialization efforts, methods, and strategies for our products or technologies will succeed, and our future revenue generation is uncertain” in Part II, Item 1A of this report for further discussion of these risks.
Revenue from sales of ORLADEYO for the three and six months ended June 30, 2023 is discussed under “Results of Operations” in this MD&A. Revenue from sales of ORLADEYO in future periods is subject to uncertainties and will depend on several factors, including the success of our and our partners’ commercialization efforts in the United States and elsewhere, the number of new patients switching to ORLADEYO, patient retention and demand, the number of physicians prescribing ORLADEYO, the rate of monthly prescriptions, reimbursement from third-party and government payors, the number of patients receiving free product, the conversion of patients from our clinical trials and early access programs to commercial customers, our pricing strategy, and market trends. We are continuing to monitor and analyze this data as we continue to commercialize ORLADEYO. The percentage of U.S. ORLADEYO patients receiving paid drug improved in the three months ended June 30, 2023, as we made progress converting commercially-insured patients who had been receiving long-term free product and as patients who received temporary free product during the first quarter prescription re-authorization process returned to reimbursed product in the three months ended June 30, 2023.
Complement Program. The goal of our overall complement program is to advance several first-in-class and/or best-in-class compounds across multiple pathways in the complement system to treat many complement-mediated diseases. These compounds include BCX10013, a potential once-daily oral medicine, which targets the alternative pathway of complement. In addition, we are pursuing oral medicines directed at other targets across the classical, lectin, and terminal pathways of the complement system, including C2, a critical upstream serine protease enzyme for activation of the classical and lectin pathways. We have developed potent, selective molecules targeting C2, which are currently in lead optimization.
RAPIVAB®/RAPIACTA®/PERAMIFLU® (peramivir injection). RAPIVAB (peramivir injection) is approved in the United States for the treatment of acute uncomplicated influenza for patients six months and older. Peramivir injection is
27

also approved in Canada (RAPIVAB), Australia (RAPIVAB), Japan (RAPIACTA), Taiwan (RAPIACTA), and Korea (PERAMIFLU).
Revenues and Expenses
Our revenues are difficult to predict and depend on several factors, including those discussed in the “Risk Factors” section in Part II, Item 1A of this report. For example, our revenues depend, in part, on regulatory approval decisions for our products and product candidates, the effectiveness of our and our collaborative partners’ commercialization efforts, market acceptance of our products, particularly ORLADEYO, and the resources dedicated to our products and product candidates by us and our collaborative partners, as well as entering into or modifying licensing agreements for our product candidates. Furthermore, revenues related to our collaborative development activities are dependent upon the progress toward, and the achievement of, developmental milestones by us or our collaborative partners.
Our operating expenses are also difficult to predict and depend on several factors, including research and development expenses, drug manufacturing, clinical research activities, the ongoing requirements of our development programs, the costs of commercialization, the availability of capital and direction from regulatory agencies, which are difficult to predict, and the factors discussed in the “Risk Factors” section in Part II, Item 1A of this report. Management may be able to control the timing and level of research and development and selling, general and administrative expenses, but many of these expenditures will occur irrespective of our actions due to contractually committed activities and/or payments.
As a result of these factors, we believe that period-to-period comparisons are not necessarily meaningful, and you should not rely on them as an indication of future performance. Due to the foregoing factors, it is possible that our operating results will be below the expectations of market analysts and investors. In such event, the prevailing market price of our common stock could be materially adversely affected.
Critical Accounting Policies and Estimates
The accompanying discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements and the related disclosures, which have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). The preparation of these consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosure of contingent assets and liabilities. We evaluate our estimates, judgments and the policies underlying these estimates on a periodic basis, as situations change, and regularly discuss financial events, policies, and issues with members of our audit committee and our independent registered public accounting firm. In particular, we routinely evaluate our estimates and policies regarding revenue recognition, administration, inventory and manufacturing, taxes, stock-based compensation, research and development, consulting and other expenses and any associated liabilities. Our estimates are based on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. The results of our estimates form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. See “Critical Accounting Estimates” at the end of this MD&A for a description of accounting policies that we believe are the most critical to aid you in fully understanding and evaluating our reported financial results and that affect the more significant judgments and estimates that we use in the preparation of our financial statements.
Recent Developments
ORLADEYO® (berotralstat)
On April 27, 2023, we announced that new data from the APeX-S clinical trial, which evaluated ORLADEYO for the prophylactic treatment of HAE, showed sustained reduction in disease burden for patients across multiple subgroups through 96 weeks of treatment.
On May 22, 2023, we announced that the Public Health Institute of Chile has granted marketing authorization for ORLADEYO for the prophylaxis of HAE in patients 12 years of age or older. We have an exclusive collaboration with Pint Pharma GmbH (“Pint”) to register and promote ORLADEYO in the pan-Latin America region. Under the terms of the agreement, Pint is responsible for obtaining and maintaining all marketing authorizations and for commercializing ORLADEYO in the region.
On July 19, 2023, we announced that we have entered into a collaboration with Er-Kim Pharmaceuticals to commercialize ORLADEYO in Turkey.
28

Complement-Mediated Diseases

BCX10013

On August 3, 2023, we announced that we have begun opening clinical trial sites for a dose-ranging trial in patients with paroxysmal nocturnal hemoglobinuria (PNH) and expect to begin patient enrollment (in countries without other approved therapies) by the end of the year. The trial is designed to identify a safe, effective, once-daily dose that we can advance into a pivotal program in renal complement-mediated diseases. We also plan to complete an additional cohort of our multiple ascending dose trial (MAD) of BCX10013, at a higher dose (160 mg QD), in healthy volunteers to provide further information to the pharmacokinetic model.
Refinancing Transaction

On April 17, 2023, we entered into a $450.0 million Loan Agreement (the “Pharmakon Loan Agreement”) with BioPharma Credit Investments V (Master) LP and BPCR Limited Partnership, as lenders, and BioPharma Credit PLC, as collateral agent for the lenders. Certain of our wholly-owned subsidiaries are guarantors to the Pharmakon Loan Agreement. The Pharmakon Loan Agreement provides for an initial term loan in the principal amount of $300 million (the “Tranche A Loan”), which was funded on April 17, 2023 (the “Tranche A Closing Date”). We utilized the proceeds from the Tranche A Loan to repay the approximate $241.8 million of outstanding indebtedness under our then-existing credit facility with Athyrium Opportunities III Co-Invest 1 LP (the “Athyrium Credit Agreement”) and to pay transaction costs and fees, and we intend to use the remaining net proceeds of approximately $26.1 million for other general corporate purposes. The Pharmakon Loan Agreement also provides for three additional term loan tranches in principal amounts of $50.0 million each, which we may request, at our option, on or prior to September 30, 2024. The maturity date of the Pharmakon Loan Agreement is April 17, 2028, the fifth anniversary of the Tranche A Closing Date. See “Note 7—Debt—Pharmakon Loan Agreement” in the Notes to Consolidated Financial Statements in Part I, Item 1 of this report for additional information about our obligations under the Pharmakon Loan Agreement.

Collectively, the prepayment and final payment fees and unamortized deferred financing costs associated with repayment of the Athyrium Credit Agreement totaled $29.0 million and are reflected as a one-time loss on extinguishment of debt on the Consolidated Statements of Comprehensive Loss for the three and six months ended June 30, 2023. See “Note 7—Debt—Athyrium Credit Agreement” in the Notes to Consolidated Financial Statements in Part I, Item 1 of this report for additional information about this extinguishment of debt.
Results of Operations (three months ended June 30, 2023 compared to the three months ended June 30, 2022)
For the three months ended June 30, 2023, total revenues were $82.5 million as compared to $65.5 million for the three months ended June 30, 2022. The increase was primarily due to ORLADEYO net revenue, including royalties, of $81.0 million, an increase of $15.8 million.
Cost of product sales for the three months ended June 30, 2023 and 2022 was $0.9 million and $0.2 million, respectively. The increase in cost of product sales was due to an increase in ORLADEYO sales as compared to the prior year period as well as the utilization of validation materials and product in the prior year period, the cost of which was expensed prior to product launch.
Research and development (“R&D”) expenses decreased to $51.2 million for the three months ended June 30, 2023 from $62.0 million for the three months ended June 30, 2022, primarily due to reduced R&D investment following the discontinuation of the BCX9930 and BCX9250 programs announced in December and November 2022, respectively. These reductions were partially offset by increased spending on berotralstat development programs and other research, preclinical and development costs.

Total R&D expenses$51,247 $61,990 
Selling, general and administrative (“SG&A”) expenses for the three months ended June 30, 2023 were $51.0 million compared to $38.0 million for the three months ended June 30, 2022. The increase was primarily due to increased investment to expand and enhance the U.S. commercial team and expanded international operations.
Interest expense for the three months ended June 30, 2023 was $28.9 million compared to $24.0 million for the three months ended June 30, 2022. The increase in interest expense was primarily associated with the interest accrued on the larger Pharmakon Tranche A Loan of $300.0 million. On April 17, 2023, we entered into the Pharmakon Loan Agreement. The Pharmakon Loan Agreement provides for an initial term loan, the Tranche A Loan, in the principal amount of $300.0 million, which was funded on April 17, 2023 and was primarily used to repay the outstanding Athyrium Credit Agreement principal balance, outstanding interest accrued on the Athyrium term loans and associated prepayment and final payment fees totaling $263.0 million.
Interest expense for the three months ended June 30, 2023 included $19.5 million of non-cash interest expense due to the amortization of interest associated with the royalty financing obligations, $7.9 million of interest expense, including the amortization of the deferred financing associated with the borrowings under the Pharmakon Loan Agreement, and $1.5 million of interest expense, including the amortization of the deferred financing associated with the borrowings under the Athyrium Credit Agreement. Interest expense for the three months ended June 30, 2022 included $19.7 million of non-cash interest expense due to the amortization of interest associated with the royalty financing obligations and $4.3 million of interest expense, net of deferred financing amortization, associated with the Term A Loan under the Athyrium Credit Agreement.
For the three months ended June 30, 2023, other expense of $25.0 million was comprised primarily of a loss on extinguishment of debt of $29.0 million on the repayment of the term loans under the Athyrium Credit Agreement, partially offset by interest income of $3.8 million and net foreign currency gains of $0.3 million. Other income of $0.7 million for the three months ended June 30, 2022 was comprised of interest income of $0.6 million and net foreign currency gains of $0.1 million.
Results of Operations (six months ended June 30, 2023 compared to the six months ended June 30, 2022)
For the six months ended June 30, 2023, total revenues were $151.3 million as compared to $115.5 million for the six months ended June 30, 2022. The increase was primarily due to ORLADEYO net revenue, including royalties, of $149.4 million, an increase of $34.5 million.
Cost of product sales for the six months ended June 30, 2023 and 2022 was $1.8 million and $0.5 million, respectively. The increase in cost of product sales was due to an increase in ORLADEYO sales as compared to the prior year period as well as the utilization of validation materials and product in the prior year period, the cost of which was expensed prior to product launch. Additionally, for the six months ended June 30, 2023, an inventory valuation reserve of $0.2 million was recorded for inventory, primarily ORLADEYO, that was at risk of expiration prior to usage.
R&D expenses decreased to $99.6 million for the six months ended June 30, 2023 from $127.4 million for the six months ended June 30, 2022, primarily due to reduced R&D investment following the discontinuation of the BCX9930 and
30

BCX9250 programs announced in December and November 2022, respectively. These reductions were partially offset by increased spending on berotralstat development programs and other research, preclinical and development costs.

SG&A expenses for the six months ended June 30, 2023 were $98.9 million compared to $72.3 million for the six months ended June 30, 2022. The increase was primarily due to increased investment to expand and enhance the U.S. commercial team and expanded international operations.
Interest expense for the six months ended June 30, 2023 was $56.3 million compared to $47.9 million for the six months ended June 30, 2022. The increase in interest expense was primarily associated with the interest accrued on the larger Pharmakon Tranche A Loan of $300.0 million. Additionally, the increase in interest expense was due to the additional aggregate borrowing of $75.0 million of the Term B Loan and Term C Loan under the Athyrium Credit Agreement, which were funded on July 29, 2022.
Interest expense for the six months ended June 30, 2023 included $38.8 million of non-cash interest expense due to the amortization of interest associated with the royalty financing obligations, $7.9 million of interest expense, including the amortization of the deferred financing associated with the borrowings under the Pharmakon Loan Agreement and $9.5 million of interest expense, net of deferred financing amortization, associated with the borrowings under the Athyrium Credit Agreement. Interest expense for the six months ended June 30, 2022 included $39.4 million of non-cash interest expense due to the amortization of interest associated with the royalty financing obligations and $8.4 million of interest expense, net of deferred financing amortization, associated with the Term A Loan under the Athyrium Credit Agreement.
For the six months ended June 30, 2023, other expense of $21.8 million was comprised primarily of a loss on extinguishment of debt of $29.0 million on the repayment of the term loans under the Athyrium Credit Agreement, partially offset by interest income of $7.1 million and net foreign currency gains of $0.1 million. Other income of $0.6 million for the six months ended June 30, 2022 was comprised of interest income of $0.7 million, partially offset by net foreign currency losses of $0.1 million.
Liquidity and Capital Resources
Our operations have principally been funded through public offerings and private placements of equity securities; our credit facilities; revenues from ORLADEYO; royalty monetization transactions; and cash from collaborative and other research and development agreements, including U.S. Government contracts. In addition to the above, we have previously received funding from other sources, including other collaborative and other research and development agreements, government grants, equipment lease financing, facility leases, research grants, and interest income on our investments.
On April 17, 2023, we entered into the Pharmakon Loan Agreement. The Pharmakon Loan Agreement provides for an initial $300 million Tranche A Loan, which was funded on April 17, 2023. We utilized the proceeds from the Tranche A Loan to repay the approximate $241.8 million of outstanding indebtedness under the then-existing Athyrium Credit Agreement and to pay transaction costs and fees, and we intend to use the remaining net proceeds of approximately $26.1 million for other general corporate purposes. The Pharmakon Loan Agreement also provides for three additional term loan tranches in principal amounts of $50.0 million each, which we may request, at our option, on or prior to September 30, 2024. The maturity date of the Pharmakon Loan Agreement is April 17, 2028. See “Note 7—Debt—Pharmakon Loan
31

Agreement” in the Notes to Consolidated Financial Statements in Part I, Item 1 of this report for additional information about our obligations under the Pharmakon Loan Agreement.
In 2020 and 2021, we entered into the Royalty Purchase Agreements (as defined in “Note 6—Royalty Monetizations—ORLADEYO and Factor D Inhibitors” in the Notes to Consolidated Financial Statements in Part I, Item 1 of this report) with RPI 2019 Intermediate Finance Trust (“RPI”) and OCM IP Healthcare Holdings Limited, an affiliate of OMERS Capital Markets (“OMERS”). Under the Royalty Purchase Agreements, RPI and OMERS are entitled to receive tiered, sales-based royalties on net product sales of ORLADEYO in the United States and certain key European markets (collectively, the “Key Territories”), and other markets where we sell ORLADEYO directly or through distributors. In addition, RPI and OMERS are entitled to receive a tiered revenue share on amounts generally received by us on account of ORLADEYO sublicense revenue or net sales by licensees outside of the Key Territories. We will be required to make payments to OMERS commencing with the calendar quarter beginning October 1, 2023. See “Note 6—Royalty Monetizations—ORLADEYO and Factor D Inhibitors” in the Notes to Consolidated Financial Statements in Part I, Item 1 of this report for additional information about these financing transactions.
As of June 30, 2023, we had net working capital of $417.6 million, an increase of approximately $6.6 million from $411.0 million at December 31, 2022. The increase in working capital was primarily the result of net proceeds of $26.1 million received following the funding of the Tranche A Loan of $300.0 million under the Pharmakon Loan Agreement. Our principal sources of liquidity at June 30, 2023 were approximately $146.2 million in cash and cash equivalents and approximately $264.5 million in investments considered available-for-sale.
We intend to contain costs and cash flow requirements by closely managing our third-party costs and headcount, leasing scientific equipment and facilities, contracting with other parties to conduct certain research and development projects, and using consultants. We expect to incur additional expenses, potentially resulting in significant losses, as we continue to pursue our research and development activities, commercialize ORLADEYO, and hire additional personnel. We may incur additional expenses related to the filing, prosecution, maintenance, defense, and enforcement of patent and other intellectual property claims and additional regulatory costs as our clinical programs advance through later stages of development. The objective of our investment policy is to ensure the safety and preservation of invested funds, as well as to maintain liquidity sufficient to meet cash flow requirements. We place our excess cash with high credit quality financial institutions, commercial companies, and government agencies in order to limit the amount of our credit exposure. We have not realized any significant losses on our investments.
We plan to finance our needs principally from the following:
lease, royalty, or loan financing;
public or private equity and/or debt financing;
our existing capital resources and interest earned on that capital;
revenues from product sales; and
payments under current or future collaborative and licensing agreements with corporate partners.
As our commercialization activities and research and development programs continue to advance, our costs will increase. Our current and planned clinical trials, plus the related development, manufacturing, regulatory approval process requirements, and additional personnel resources and testing required for the continuing development of our product candidates and the commercialization of our products will consume significant capital resources and will increase our expenses. Our expenses, revenues and cash utilization rate could vary significantly depending on many factors, including our ability to raise additional capital, the development progress of our collaborative agreements for our product candidates, the amount of funding or assistance, if any, we receive from new partnerships with third parties for the development and/or commercialization of our products and product candidates, the progress and results of our current and proposed clinical trials for our most advanced product candidates, the progress made in the manufacturing of our lead product candidates, the success of our commercialization efforts for, and market acceptance of, our products, and the overall progression of our other programs. The impact of the ongoing COVID-19 pandemic on one or more of the foregoing factors could negatively affect our revenues, expenses, and cash utilization rate.
Based on our expectations for revenue and operating expenses, we believe our financial resources will be sufficient to fund our operations for at least the next 12 months. However, we have sustained operating losses for the majority of our corporate history and expect that our 2023 expenses will exceed our 2023 revenues. We expect to continue to incur operating losses and negative cash flows until revenues reach a level sufficient to support ongoing operations. Our liquidity needs will largely be determined by the success of operations in regard to the successful commercialization of our products and the future progression of our product candidates. We regularly evaluate other opportunities to fund future operations,
32

including: (1) out-licensing rights to certain of our products or product candidates, pursuant to which we would receive cash milestone payments; (2) raising additional capital through equity or debt financings or from other sources, including royalty or other monetization transactions; (3) obtaining additional product candidate regulatory approvals, which would generate revenue, milestone payments and cash flow; (4) reducing spending on one or more research and development programs, including by discontinuing development; (5) restructuring operations to change our overhead structure; and/or (6) securing U.S. Government funding of our programs, including obtaining procurement contracts. We may issue securities, including common stock, preferred stock, depositary shares, purchase contracts, warrants, debt securities, and units, through private placement transactions or registered public offerings. Our future liquidity needs, and our ability to address those needs, will largely be determined by the success of our products and product candidates; the timing, scope, and magnitude of our research and development and commercial expenses; and key developments and regulatory events and our decisions in the future.
Our long-term capital requirements and the adequacy of our available funds will depend upon many factors, including:
market acceptance of approved products and successful commercialization of such products by either us or our partners;
our ability to receive reimbursement and stockpiling procurement contracts;
the progress and magnitude of our research, drug discovery and development programs;
changes in existing collaborative relationships;
our ability to establish additional collaborative relationships with academic institutions, biotechnology or pharmaceutical companies, governmental agencies, distributors or other third parties;
the extent to which our partners will share in the costs associated with the development of our programs or run the development programs themselves;
our ability to negotiate favorable development and marketing strategic alliances for certain products and product candidates;
any decision to build or expand internal development and commercial capabilities;
the scope and results of preclinical studies and clinical trials to identify and develop product candidates;
our ability to engage sites and enroll subjects in our clinical trials;
the scope of manufacturing of our products to support our commercial operations and of our product candidates to support our preclinical research and clinical trials;
increases in personnel and related costs to support the development and commercialization of our products and product candidates;
the scope of manufacturing of our drug substance and product candidates required for future new drug application (“NDA”) filings;
competitive and technological advances;
the time and costs involved in obtaining regulatory approvals;
post-approval commitments for ORLADEYO, RAPIVAB, and other products that receive regulatory approval; and
the costs involved in all aspects of intellectual property strategy and protection, including the costs involved in preparing, filing, prosecuting, maintaining, defending, and enforcing patent claims.
We may in the future be required to raise additional capital to complete the development and commercialization of our products and product candidates, and we may seek to raise capital in the future, including to take advantage of favorable opportunities in the capital markets. Additional funding may not be available when needed or in the form or on terms acceptable to us. Our future working capital requirements, including the need for additional working capital, will largely be determined by the advancement of our portfolio of product candidates and the commercialization of ORLADEYO. More specifically, our working capital requirements will be dependent on the number, magnitude, scope and timing of our development programs; regulatory approval of our product candidates; obtaining funding from collaborative partners; the cost, timing and outcome of regulatory reviews, regulatory investigations, and changes in regulatory requirements; the costs of obtaining patent protection for our product candidates; the timing and terms of business development activities; the rate of technological advances relevant to our operations; the efficiency of manufacturing processes developed on our behalf by third parties; the timing, scope and magnitude of commercial spending; and the level of required administrative support for our daily operations. See “Risk Factors—Risks Relating to Our Business—Financial and Liquidity Risks” and “Risk Factors—Risks Relating to Our Business—Risks Relating to Drug Development and Commercialization—If we fail to obtain additional financing or acceptable partnership arrangements as and when needed, we may be unable to complete the development and commercialization of our products and product candidates or continue operations” in Part II, Item 1A of this report for further discussion of the risks related to obtaining additional capital.

The restrictive covenants contained in the Pharmakon Loan Agreement could cause us to be unable to pursue business opportunities that we or our stockholders may consider beneficial without the lenders’ permission or without repaying all obligations outstanding under the Pharmakon Loan Agreement. These covenants limit our ability to, among other things, dispose of assets; engage in mergers, acquisitions, and similar transactions; incur additional indebtedness; grant liens; make investments; pay dividends or make distributions or certain other restricted payments in respect of equity; prepay other indebtedness; enter into restrictive agreements; undertake fundamental changes; or amend certain material contracts. A breach of any of these covenants could result in an event of default under the Pharmakon Loan Agreement. As of June 30, 2023, we were in compliance with the covenants under the Pharmakon Loan Agreement.
Critical Accounting Estimates
We have established various accounting policies that govern the application of U.S. GAAP, which were utilized in the preparation of our consolidated financial statements. Certain accounting policies involve significant judgments and assumptions by management that have a material impact on the carrying value of certain assets and liabilities. Management considers such accounting policies to be critical accounting policies. The judgments and assumptions used by management are based on historical experience and other factors, which are believed to be reasonable under the circumstances. Because of the nature of the judgments and assumptions made by management, actual results could differ from these judgments and estimates, which could have a material impact on the carrying values of assets and liabilities and the results of operations.
While our significant accounting policies are more fully described in “Note 1—Significant Accounting Policies and Concentrations of Risk” in the Notes to Consolidated Financial Statements in Part I, Item 1 of this report, we believe that the following accounting policies are the most critical to aid you in fully understanding and evaluating our reported financial results and affect the more significant judgments and estimates that we use in the preparation of our financial statements.
Revenue Recognition
Pursuant to Accounting Standards Codification (“ASC”) Topic 606, we recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve this core principle, Topic 606 includes provisions within a five step model that includes (i) identifying the contract with a customer, (ii) identifying the performance obligations in the contract, (iii) determining the transaction price, (iv) allocating the transaction price to the performance obligations, and (v) recognizing revenue when, or as, an entity satisfies a performance obligation.
At contract inception, we identify the goods or services promised within each contract, assess whether each promised good or service is distinct, and determine those that are performance obligations. We recognize as revenue the amount of the transaction price that is allocated to the respective performance obligation when the performance obligation is satisfied.
Product Sales, Net
Our principal sources of product sales are sales of ORLADEYO, which we began shipping to patients in December 2020, sales of peramivir to our licensing partners and sales of RAPIVAB to HHS under our procurement contract. In the United States, we ship ORLADEYO directly to patients through a single specialty pharmacy, which is considered our customer. In the European Union, United Kingdom and elsewhere, we sell ORLADEYO to specialty distributors as well as hospitals and pharmacies, which collectively are considered our customers.
We recognize revenue for sales when our customers obtain control of the product, which generally occurs upon delivery. For ORLADEYO, we classify payments to our specialty pharmacy customer for certain services provided by our customer as selling, general and administrative expenses to the extent such services provided are determined to be distinct from the sale of our product.
Net revenue from sales of ORLADEYO is recorded at net selling price (transaction price), which includes estimates of variable consideration for which reserves are established for (i) estimated government rebates, such as Medicaid and Medicare Part D reimbursements, and estimated managed care rebates, (ii) estimated chargebacks, (iii) estimated costs of co-payment assistance programs and (iv) product returns. These reserves are based on the amounts earned or to be claimed on the related sales and are classified as reductions of accounts receivable or as a current liability. Overall, these reserves reflect our best estimates of the amount of consideration to which we are entitled based on the terms of the applicable contract. The amount of variable consideration included in the transaction price may be constrained and is included in the net sales price only to the extent that it is probable that a significant reversal in the amount of the cumulative revenue
34

recognized will not occur in a future period. Actual amounts of consideration ultimately received may differ from our estimates. If actual results in the future vary from estimates, we adjust these estimates, which would affect net product revenue and earnings in the period such variances become known.
Government and Managed Care Rebates. We contract with government agencies and managed care organizations or, collectively, third-party payors, so that ORLADEYO will be eligible for purchase by, or partial or full reimbursement from, such third-party payors. We estimate the rebates we will provide to third-party payors and deduct these estimated amounts from total gross product revenues at the time the revenues are recognized. These reserves are recorded in the same period in which the revenue is recognized, resulting in a reduction of product revenue and the establishment of a current liability. We estimate the rebates that we will provide to third-party payors based upon (i) our contracts with these third-party payors, (ii) the government mandated discounts applicable to government-funded programs, (iii) a range of possible outcomes that are probability-weighted for the estimated payor mix, and (iv) product distribution information obtained from our specialty pharmacy.
Chargebacks. Chargebacks are discounts that occur when certain contracted customers, pharmacy benefit managers, insurance companies, and government programs purchase directly from our specialty pharmacy. These customers purchase our products under contracts negotiated between them and our specialty pharmacy. The specialty pharmacy, in turn, charges back to us the difference between the price the specialty pharmacy paid and the negotiated price paid by the contracted customers, which may be higher or lower than the specialty pharmacy’s purchase price from us. We estimate chargebacks and adjust gross product revenues and accounts receivable based on the estimates at the time revenues are recognized.
Co-payment assistance and patient assistance programs. Patients who have commercial insurance and meet certain eligibility requirements may receive co-payment assistance. Based upon the terms of the program and co-payment assistance utilization reports received from the specialty pharmacy, we are able to estimate the co-payment assistance amounts, which are recorded in the same period in which the related revenue is recognized, resulting in a reduction of product revenue. We also offer a patient assistance program that provides free drug product, for a limited period of time, to allow a patient’s insurance coverage to be established. Based on patient assistance program utilization reports provided by the specialty pharmacy, we record gross revenue of the product provided and a full reduction of the revenue amount for the free drug discount.
Product returns. We do not provide contractual return rights to our customers, except in instances where the product is damaged or defective. Non-acceptance by the patient of shipped drug product by the specialty pharmacy is reflected as a reversal of sales in the period in which the sales were originally recorded. Reserves for estimated non-acceptances by patients are recorded as a reduction of revenue in the period that the related revenue is recognized, as well as a reduction to accounts receivable. Estimates of non-acceptance are based on quantitative information provided by the specialty pharmacy.
Collaborative and Other Revenues
We have collaboration and license agreements with a number of third parties, as well as research and development agreements with certain government entities. Our primary sources of revenue from these collaborative and other research and development arrangements are license, service and royalty revenues.
Revenue from license fees, royalty payments, milestone payments, and research and development fees are recognized as revenue when the earnings process is complete and we have no further continuing performance obligations or we have completed the performance obligations under the terms of the agreement.
Arrangements that involve the delivery of more than one performance obligation are initially evaluated as to whether the intellectual property licenses granted by us represent distinct performance obligations. If they are determined to be distinct, the value of the intellectual property licenses would be recognized up-front while the research and development service fees would be recognized as the performance obligations are satisfied. For performance obligations based on services performed, we measure progress using an input method based on the effort we expend or costs we incur toward the satisfaction of the performance obligation in relation to the total estimated effort or costs. Variable consideration is assessed at each reporting period as to whether it is not subject to significant future reversal and, therefore, should be included in the transaction price at the inception of the contract. If a contract includes a fixed or minimum amount of research and development support, this also would be included in the transaction price. Changes to collaborations, such as the extensions of the research term or increasing the number of targets or technology covered under an existing agreement, are assessed for whether they represent a modification or should be accounted for as a new contract. For contracts with multiple performance obligations, revenue is allocated to each performance obligation based on its relative standalone
35

selling price. Standalone selling prices are based on observable prices at which we separately sell the products or services. If a standalone selling price is not directly observable, then we estimate the standalone selling price using either an adjusted market assessment approach or an expected cost plus margin approach, representing the amount that we believe the market is willing to pay for the product or service. Analyzing the arrangement to identify performance obligations requires the use of judgment, and each may be an obligation to deliver services, a right or license to use an asset, or another performance obligation.
Milestone payments are recognized as licensing revenue upon the achievement of specified milestones if (i) the milestone is substantive in nature and the achievement of the milestone was not probable at the inception of the agreement and (ii) we have a right to payment. Any milestone payments received prior to satisfying these revenue recognition criteria are recorded as deferred revenue.
Reimbursements received for direct out-of-pocket expenses related to research and development costs are recorded as revenue in the Consolidated Statements of Comprehensive Loss rather than as a reduction in expenses. Under our contracts with BARDA/HHS and NIAID/HHS, revenue is recognized as reimbursable direct and indirect costs are incurred.
Under certain of our license agreements, we receive royalty payments based upon our licensees’ net sales of covered products. Royalties are recognized at the later of when (i) the subsequent sale or usage occurs, or (ii) the performance obligation to which some or all of the sales-based or usage-based royalty has been satisfied.
Inventory
Our inventories primarily relate to ORLADEYO. Additionally, our inventory includes RAPIVAB and peramivir.
We value our inventories at the lower of cost or estimated net realizable value. We determine the cost of our inventories, which includes amounts related to materials, labor, manufacturing overhead and shipping and handling costs on a first-in, first-out (FIFO) basis. Raw materials and work-in-process include all inventory costs prior to packaging and labeling, including raw material, active product ingredient, and the drug product. Finished goods include packaged and labeled products.
Our inventories are subject to expiration dating. We regularly evaluate the carrying value of our inventories and provide valuation reserves for any estimated obsolete, short-dated or unmarketable inventories. In addition, we may experience spoilage of our raw materials and supplies. Our determination that a valuation reserve might be required, in addition to the quantification of such reserve, requires us to utilize significant judgment. During the six months ended June 30, 2023, we evaluated our inventory levels and associated expiration dating relative to the latest sales forecasts for ORLADEYO and RAPIVAB and estimated those inventories at risk of obsolescence. Accordingly, we recorded an increase to the inventory valuation reserve of $0.2 million for a total reserve of $1.4 million as of June 30, 2023.
We expense costs related to the production of inventories as research and development expenses in the period incurred until such time it is believed that future economic benefit is expected to be recognized, which generally is upon receipt of regulatory approval. Upon regulatory approval, we capitalize subsequent costs related to the production of inventories.
Accrued Expenses
We enter into contractual agreements with third-party vendors who provide research and development, manufacturing, distribution, and other services in the ordinary course of business. Some of these contracts are subject to milestone-based invoicing, and services are completed over an extended period of time. We record liabilities under these contractual commitments when we determine an obligation has been incurred, regardless of the timing of the invoice. This process involves reviewing open contracts and purchase orders, communicating with applicable Company personnel to identify services that have been performed on our behalf and estimating the level of service performed and the associated cost incurred for the service when we have not yet been invoiced or otherwise notified of actual cost. The majority of our service providers invoice us monthly in arrears for services performed. We make estimates of our accrued expenses as of each balance sheet date in our financial statements based on the facts and circumstances, which can include assumptions such as expected patient enrollment, site activation and estimated project duration. We periodically confirm the accuracy of our estimates with the service providers and make adjustments if necessary. Examples of estimated accrued expenses include (i) fees paid to clinical research organizations (“CROs”) in connection with preclinical and toxicology studies and clinical trials; (ii) fees paid to investigative sites in connection with clinical trials; (iii) fees paid to contract manufacturers
36

in connection with the production of our raw materials, drug substance, drug products, and product candidates; and (iv) professional fees.
We base our expenses related to clinical trials on our estimates of the services received and efforts expended pursuant to contracts with multiple research institutions and CROs that conduct and manage clinical trials on our behalf. The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven payment flows. Payments under some of these contracts depend on factors such as the successful enrollment of patients and the completion of clinical trial milestones. In accruing service fees, we estimate the time period over which services will be performed and the level of effort expended in each period. If the actual timing of the performance of services or the level of effort varies from our estimate, we will adjust the accrual accordingly. If we do not identify costs that we have begun to incur or if we underestimate or overestimate the level of these costs, our actual expenses could differ from our estimates. As of June 30, 2023 and December 31, 2022, the carrying value of accrued expenses approximates their fair value due to their short-term settlement.
Research and Development Expenses
Our research and development costs are charged to expense when incurred. Research and development expenses include all direct and indirect development costs related to the development of our portfolio of product candidates. Advance payments for goods or services that will be used or rendered for future research and development activities are deferred and capitalized. Such amounts are recognized as expense when the related goods are delivered or the related services are performed. Research and development expenses include, among other items, personnel costs, including salaries and benefits, manufacturing costs, clinical, regulatory, and toxicology services performed by CROs, materials and supplies, and overhead allocations consisting of various administrative and facilities related costs, as well as termination fees and other commitments associated with discontinued programs. Most of our manufacturing and clinical and preclinical studies are performed by third-party CROs. Costs for studies performed by CROs are accrued by us over the service periods specified in the contracts, and estimates are adjusted, if required, based upon our ongoing review of the level of services actually performed.
Additionally, we have license agreements with third parties which require fees related to sublicense agreements or maintenance fees. We expense sublicense payments as incurred unless they are related to revenues that have been deferred, in which case the expenses are deferred and recognized over the related revenue recognition period. We expense maintenance payments as incurred.
Deferred collaboration expenses represent sublicense payments paid to our academic partners upon receipt of consideration from various commercial partners, and other consideration paid to our academic partners for modification to existing license agreements. These deferred expenses would not have been incurred without receipt of such payments or modifications from our commercial partners and are being expensed in proportion to the related revenue being recognized. We believe that this accounting treatment appropriately matches expenses with the associated revenue.
We group our R&D expenses into two major categories: direct external expenses and indirect expenses. Direct expenses consist of compensation for R&D personnel and costs of outside parties to conduct laboratory studies, develop manufacturing processes and manufacture the product candidate, conduct and manage clinical trials, as well as other costs related to our clinical and preclinical studies. Additionally, direct expenses consist of those costs necessary to discontinue and close out a development program, including termination fees and other commitments. These costs are accumulated and tracked by active program. Indirect expenses consist of lab supplies and services, facility expenses, depreciation of development equipment and other overhead of our research and development efforts. These costs apply to work on non-active product candidates and our discovery research efforts.
Stock-Based Compensation
All share-based payments, including grants of stock option awards and restricted stock unit awards, are recognized in our Consolidated Statements of Comprehensive Loss based on their fair values. Stock-based compensation cost is estimated at the grant date based on the fair value of the award and is recognized as expense on a straight-line basis over the requisite service period of the award. Determining the appropriate fair value model and the related assumptions for the model requires judgment, including estimating the life of an award, the stock price volatility, and the expected term. We utilize the Black-Scholes option-pricing model to value our stock option awards and recognize compensation expense on a straight-line basis over the vesting periods. The estimation of share-based payment awards that will ultimately vest requires judgment, and to the extent actual results or updated estimates differ from our current estimates, such amounts will be recorded as a cumulative adjustment in the period estimates are revised. In addition, we have outstanding performance-based stock options and restricted stock units for which no compensation expense is recognized until “performance” is
37

deemed to have occurred. Significant management judgment is also required in determining estimates of future stock price volatility and forfeitures to be used in the valuation of the options. Actual results, and future changes in estimates, may differ substantially from our current estimates.
Interest Expense and Royalty Financing Obligations
The royalty financing obligations are eligible to be repaid based on royalties from net sales of ORLADEYO and BCX10013. Interest expense is accrued using the effective interest rate method over the estimated period each of the related liabilities will be paid. This requires us to estimate the total amount of future royalty payments to be generated from product sales over the life of the agreement. We impute interest on the carrying value of each of the royalty financing obligations and record interest expense using an imputed effective interest rate. We reassess the expected royalty payments each reporting period and account for any changes through an adjustment to the effective interest rate on a prospective basis. The assumptions used in determining the expected repayment term of the debt and amortization period of the issuance costs requires that we make estimates that could impact the carrying value of each of the liabilities, as well as the periods over which associated issuance costs will be amortized. A significant increase or decrease in forecasted net sales could materially impact each of the liability balances, interest expense and the time periods for repayment.
Income Taxes
The liability method is used in our accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based on differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that are expected to be in effect when the differences are expected to reverse.
We account for uncertain tax positions in accordance with U.S. GAAP. Significant management judgment is required in determining our provision for income taxes, deferred tax assets and liabilities and any valuation allowance recorded against net deferred tax assets. We have recorded a valuation allowance against substantially all potential tax assets, due to uncertainties in our ability to utilize deferred tax assets, primarily consisting of certain net operating losses carried forward, before they expire. The valuation allowance is based on estimates of taxable income in each of the jurisdictions in which we operate and the period over which our deferred tax assets will be recoverable.
Beginning in fiscal year 2021, we began accruing for U.S. state taxes and foreign income taxes as a result of increased nexus in both U.S. state and foreign jurisdictions where historically we had no presence.
In addition, starting in 2022, amendments to Section 174 of the Internal Revenue Code of 1986, as amended (“IRC”), no longer permit an immediate deduction for research and development expenditures in the tax year that such costs are incurred. Instead, these IRC Section 174 development costs must now be capitalized and amortized over either a five- or 15-year period, depending on the location of the activities performed. The new amortization period begins with the midpoint of any taxable year that IRC Section 174 costs are first incurred, regardless of whether the expenditures were made prior to or after July 1, and runs until the midpoint of year five for activities conducted in the United States or year 15 in the case of development conducted on foreign soil.
Recent Accounting Pronouncements
“Note 1—Significant Accounting Policies and Concentrations of Risk” in the Notes to Consolidated Financial Statements included in Part I, Item 1 of this report discusses accounting pronouncements recently issued or proposed but not yet required to be adopted.
Item 3.    Quantitative and Qualitative Disclosures about Market Risk
Interest Rate Risk
We are subject to interest rate risk on our investment portfolio and borrowings under our Pharmakon Loan Agreement. The Tranche A Loan under the Pharmakon Loan Agreement accrues interest each quarter at a rate equal to the three-month Secured Overnight Financing Rate (“SOFR”), which is capped to be no less than 1.75%, plus 7.00% or, for each quarterly interest period in which a Pharmakon PIK Interest Payment is made, SOFR plus 7.25%. Accordingly, increases in interest rates will increase the associated interest payments that we are required to make on the Tranche A Loan. As of June 30, 2023, interest was accrued at an effective rate of 12.24% on the $300.0 million borrowing under the Pharmakon Loan Agreement.

We invest in marketable securities in accordance with our investment policy. The primary objectives of our investment policy are to preserve capital, maintain proper liquidity to meet operating needs and maximize yields. Our investment policy specifies credit quality standards for our investments and limits the amount of credit exposure to any single issue, issuer or type of investment. We place our excess cash with high credit quality financial institutions, commercial companies, and government agencies in order to limit the amount of credit exposure. Some of the securities we invest in may have market risk. This means that a change in prevailing interest rates may cause the principal amount of the investment to fluctuate.
Our investment exposure to market risk for changes in interest rates relates to the increase or decrease in the amount of interest income we can earn on our portfolio, changes in the market value due to changes in interest rates and other market factors as well as the increase or decrease in any realized gains and losses. Our investment portfolio includes only marketable securities and instruments with active secondary or resale markets to help ensure portfolio liquidity. A hypothetical 100 basis point increase or decrease in interest rates along the entire interest rate yield curve would not significantly affect the fair value of our interest sensitive financial instruments, including our borrowings, but may affect our future earnings and cash flows. We generally have the ability to hold our fixed-income investments to maturity and, therefore, do not expect that our operating results, financial position or cash flows will be materially impacted due to a sudden change in interest rates. However, our future investment income may fall short of expectations due to changes in interest rates, or we may suffer losses in principal if forced to sell securities which have declined in market value due to changes in interest rates or other factors, such as changes in credit risk related to the securities’ issuers. To minimize this risk, we schedule our investments to have maturities that coincide with our expected cash flow needs, thus avoiding the need to redeem an investment prior to its maturity date. Accordingly, we do not believe that we have material exposure to interest rate risk arising from our investments. Generally, our investments are not collateralized. We have not realized any significant losses from our investments.
We do not use interest rate derivative instruments to manage exposure to interest rate changes. We ensure the safety and preservation of invested principal funds by limiting default risk, market risk and reinvestment risk. We reduce default risk by investing in investment grade securities.
Foreign Currency Risk
Most of our revenues and expenses are denominated in U.S. dollars. Our commercial sales in Europe are primarily denominated in Euros and the British Pound. We also had other transactions denominated in foreign currencies during the six months ended June 30, 2023, primarily related to operations in Europe, contract manufacturing and ex-U.S. clinical trial activities, and we expect to continue to do so. Our royalties from Torii are derived from Torii’s sales of ORLADEYO in Japan. Those sales are denominated in Japanese yen and converted into U.S. dollars for purposes of determining the royalty owed to us. Our limited foreign currency exposure relative to our European operations is to fluctuations in the Euro, British Pound, Swiss Franc, Danish Krone, and Swedish Krona. Additionally, we have initiated operations in Canada and have foreign currency exposure to the Canadian Dollar.
We do not anticipate that foreign currency transaction gains or losses will be significant at our current level of operations. However, transaction gains or losses may become significant in the future as we continue to expand our operations internationally. We have not engaged in foreign currency hedging during the six months ended June 30, 2023; however, we may do so in the future.
Inflation Risk
Inflation generally impacts us by potentially increasing our operating expenses, including clinical trial costs and selling activities. We do not believe that inflation has had a material impact on our business or results of operations during the periods for which the condensed consolidated financial statements are presented in this report. Significant adverse changes in inflation could negatively impact our future results of operations.
Item 4.    Controls and Procedures
We maintain a set of disclosure controls and procedures that are designed to ensure that information relating to the Company required to be disclosed in our periodic filings under the Exchange Act is recorded, processed, summarized and reported in a timely manner under the Exchange Act. We carried out an evaluation, under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that, as of June 30, 2023, the Company’s disclosure controls and procedures are effective to ensure that information required to be disclosed by the Company in the reports filed or submitted by it under
39

the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and include controls and procedures designed to ensure that information required to be disclosed by the Company in such reports is accumulated and communicated to the Company’s management, including the Chief Executive Officer and Chief Financial Officer of the Company, as appropriate to allow timely decisions regarding required disclosure.
There have been no changes in our internal control over financial reporting that occurred during the quarter ended June 30, 2023 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II. OTHER INFORMATION
Item 1A. Risk Factors
An investment in our stock involves risks. You should carefully read this entire report and consider the following uncertainties and risks, which may adversely affect our business, financial condition or results of operations, along with all of the other information included in our other filings with the SEC, before making an investment decision regarding our common stock.
Risks Relating to Our Business
Risks Relating to COVID-19
Our business, operations, clinical development or commercialization plans and timelines, and access to capital could be adversely affected by the effects of the ongoing COVID-19 pandemic on us or on third parties with whom we conduct business, including without limitation our development partners, manufacturers, CROs, and others, as well as on the regulatory and government agencies with whom we work.
The global COVID-19 pandemic continues to affect the United States and global economies, and could cause disruptions to our business, operations, and clinical development or commercialization plans and timelines, as well as the business and operations of third parties with whom we conduct business. For example, government orders and evolving business policies and procedures have impacted and may continue to impact, among other things: (1) our personnel and those of third parties on whom we rely, including our development partners, manufacturers, CROs, and others; (2) the conduct of our current and future clinical trials and commercial interactions; and (3) the operations of the FDA, European Medicines Agency (“EMA”), Japanese Pharmaceuticals and Medical Devices Agency (“PMDA”), and other health and governmental authorities, which could result in delays of reviews and approvals, including as we continue to expand internationally and bring ORLADEYO to additional global markets.
If our operations or those of third parties with whom we conduct business are impaired or curtailed as a result of these events, the development and commercialization of our products and product candidates could be stopped or delayed, or the costs of such development and commercialization activities could increase, any of which could have a material adverse impact on our business. For example, our suppliers or other vendors may be unable to meet their obligations to us or perform their services as expected as a result of the COVID-19 pandemic or other health epidemics. In such circumstances, we may not be able to enter into arrangements with alternative suppliers or vendors or do so on commercially reasonable terms or in a timely manner. Such delays could adversely impact our ability to meet our desired clinical development and any commercialization timelines. Although we carefully manage our relationships with our suppliers and vendors, there can be no assurance that we will not encounter challenges or delays in the future or that these challenges or delays will not have an adverse impact on our business, financial condition and prospects.
In addition, our clinical trials have been and may continue to be affected by the COVID-19 pandemic. For example, the acceleration of COVID-19 slowed the startup of the inadequate C5 responder cohorts in our complement oral Factor D program and, as a result, delayed the reporting of related data in 2020. Clinical site initiation and patient enrollment may be delayed due to prioritization of hospital resources toward the COVID-19 pandemic or concerns among patients about participating in clinical trials during a pandemic. Some patients may have difficulty following certain aspects of clinical trial protocols if quarantines impede patient movement or interrupt healthcare services. Similarly, our inability to successfully recruit and retain patients and principal investigators and site staff who, as healthcare providers, may have heightened exposure to COVID-19 or experience additional restrictions by their institutions, city, or state could adversely impact our clinical trial operations.
If global health concerns prevent the FDA, EMA, PMDA or other regulatory authorities from conducting their inspections, reviews, or other regulatory activities, it could significantly impact the ability of such
