Item 2.    Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following Management’s Discussion and Analysis (“MD&A”) is intended to help the reader understand our results of operations and financial condition. This MD&A is provided as a supplement to, and should be read in conjunction with, our unaudited condensed 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 global biotechnology company focused on developing and commercializing medicines for hereditary angioedema (“HAE”) and other rare diseases, driven by our deep commitment to improving the lives of people living with these conditions. We have built a robust commercial infrastructure to support the successful commercialization of ORLADEYO, an oral, once-daily therapy discovered and developed internally for the prevention of HAE attacks. Our business strategy includes leveraging this established commercial platform to successfully commercialize a pipeline of potential first-in-class or best-in-class oral small-molecule and injectable protein therapeutics targeting a range of rare diseases. These programs are being pursued through both internal discovery efforts and strategic business development. By utilizing our existing commercial capabilities and focusing on rare disease markets, we believe that we can most effectively optimize our costs and strategically allocate resources to support long-term, sustainable growth.

Products and Product Candidates

ORLADEYO® (berotralstat)

ORLADEYO is an oral, once-daily therapy discovered and developed by us for the prevention of HAE attacks. A capsule formulation of ORLADEYO is approved in the United States and other global markets for the prevention of HAE attacks in adults and pediatric patients 12 years and older. In addition, in December 2025, the FDA approved an oral pellet formulation of once-daily ORLADEYO for prophylactic therapy in pediatric patients with HAE aged 2 to 12 years.

Based on proprietary analyses of HAE prevalence and market research studies with HAE patients, physicians, and payors in the United States and Europe, and over five years of commercialization experience with ORLADEYO, we anticipate that the global commercial market for ORLADEYO has the potential to reach a global peak of $1 billion in annual net ORLADEYO revenues. Based on our commercialization experience with ORLADEYO, we believe there is a seasonal impact to our business in the first quarter of each year due to typical first quarter requirements from payors for prescription reauthorization of specialty products, like ORLADEYO, that can temporarily move patients from paid drug to free product. 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 Product 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 months ended March 31, 2026 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, but not limited to, 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, our pricing strategy, and market trends. We monitor and analyze this data on an ongoing basis as we continue to commercialize ORLADEYO and adjust our forecasts accordingly. In addition, on May 6, 2026, we announced that we recently identified a manufacturing issue that will delay the initial product fulfillment of the oral pellet formulation of ORLADEYO. We are currently evaluating the impact of this delay and cannot predict at this time whether or to what extent it may affect future revenue or operating results.

Navenibart (STAR-0215)

On January 23, 2026, we completed the previously announced Merger with Astria (each term as defined below). Pursuant to the Merger, we acquired Astria’s lead product candidate navenibart, an injectable monoclonal antibody designed to inhibit plasma kallikrein for the treatment of HAE. Navenibart is currently in Phase 3 clinical development, and the FDA has granted Fast Track and Orphan Drug designations to navenibart for the treatment of HAE. In addition, the

33

Table of Contents

European Commission has granted Orphan Medicinal Product Designation to navenibart for the treatment of HAE. The goal for navenibart is to develop a potentially best-in-class injectable prophylactic therapy with a differentiated every 3- and 6-month administration schedule, which could offer significant improvements over existing injectable options and address key unmet needs in the HAE patient community.

BCX17725 (Netherton syndrome)

BCX17725 is a potent and selective investigational protein therapeutic KLK5 inhibitor designed to provide best-in-class, potentially disease-modifying, treatment for people with Netherton syndrome. Netherton syndrome is a serious, rare, lifelong genetic disorder causing disruption of the skin barrier with premature separation of the skin layers, chronic inflammation and vulnerability to serious infections, caused by lack of normal function of a natural inhibitor of KLK5. People with Netherton syndrome often have itchy, red, scaly, inflamed skin, fragile hair, and are more likely to develop severe food allergies, asthma and eczema. Netherton syndrome can be life-threatening, especially during infancy when patients are vulnerable to dehydration and recurrent infections. Currently, there are no approved treatments that target the underlying cause of Netherton syndrome. BCX17725 is designed to replace missing functions of the natural KLK5 inhibitor, which could restore the normal skin barrier and result in improved skin function, including protection from severe inflammatory and infectious complications of the disease.

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 also approved in Canada (RAPIVAB), Australia (RAPIVAB), Japan (RAPIACTA), Taiwan (RAPIACTA), and Korea (PERAMIFLU).

STAR-0310

Pursuant to the Merger, on the Closing Date, we acquired STAR-0310, which is a monoclonal antibody OX40 antagonist that incorporates YTE half-life extension technology for the treatment of atopic dermatitis (“AD”) and potentially other indications. STAR-0310 was designed as a potentially best-in-class, long-acting OX40 inhibitor with the goal of addressing the need for a safe, effective, and infrequently administered AD treatment. AD is an immune disorder associated with loss of skin barrier function and itching and is caused by diverse mechanisms, spanning the spectrum of T cell-driven pathology. STAR-0310 is currently in a Phase 1a trial to assess the safety, tolerability, pharmacokinetics, and immunogenicity of STAR-0310 in healthy subjects. We plan to seek strategic alternatives for this asset.

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 primarily on research and development activities, including clinical research activities, and the ongoing requirements of our development programs, as well as the costs of commercialization, drug manufacturing, direction from regulatory agencies 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.

Recent Developments

Navenibart (STAR-0215)

On February 26, 2026, we announced that new positive, interim results from the long‑term, open‑label ALPHA‑SOLAR trial show sustained, robust HAE attack suppression with navenibart administered every three and six months. In addition, we announced on May 6, 2026 that patient enrollment in ALPHA-ORBIT, the ongoing pivotal study of navenibart for the prophylaxis of HAE, is on track to be completed by the end of June 2026.

On May 4, 2026, we announced that we entered into a licensing agreement granting an Irish affiliate of Neopharmed Gentili S.p.A. (“Neopharmed”) exclusive rights to commercialize navenibart for HAE in Europe. We received upfront consideration of $70.0 million and will be eligible to receive up to $275.0 million in future regulatory and sales milestone payments. We will also receive tiered royalties on net sales ranging from 18% to 30%. Navenibart is an investigational product that has not yet received regulatory approval in the United States or Europe.

BCX17725 (Netherton syndrome)

On May 6, 2026, we announced that we have begun dosing in Part 4 of a Phase 1 trial of BCX17725 for the treatment of Netherton syndrome, which will enroll up to 12 patients for three months.

Avoralstat

In the first quarter of 2026, we ended development of avoralstat, a plasma kallikrein inhibitor for the treatment of diabetic macular edema, to focus our pipeline on rare diseases.

Astria Therapeutics, Inc. Merger

On October 14, 2025, we entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Axel Merger Sub, Inc., a Delaware corporation and our wholly owned subsidiary (“Merger Sub”), and Astria Therapeutics, Inc., a Delaware corporation (“Astria”). Pursuant to the Merger Agreement, on January 23, 2026 (the “Closing Date”), Merger Sub merged with and into Astria, with Astria surviving as our wholly owned subsidiary (the “Merger”).

We have built a robust commercial infrastructure to support the successful commercialization of ORLADEYO, an oral, once-daily therapy discovered and developed internally for the prevention of HAE attacks. Our business strategy includes leveraging this established commercial platform to successfully commercialize a pipeline of potential first-in-class or best-in-class oral small molecule and injectable protein therapeutics targeting a range of rare diseases. These programs are being pursued through both internal discovery efforts and strategic business development. By utilizing our existing commercial capabilities and focusing on rare disease markets, we believe that we can more effectively optimize our costs and strategically allocate resources to support long-term, sustainable growth.

Products and Product Candidates

ORLADEYO® (berotralstat)

ORLADEYO is an oral, once-daily therapy discovered and developed by us for the prevention of HAE attacks. A capsule formulation of ORLADEYO is approved in the United States and other global markets for the prevention of HAE attacks in adults and pediatric patients 12 years and older. In addition, in December 2025, the FDA approved an oral pellet formulation of once-daily ORLADEYO for prophylactic therapy in pediatric patients with HAE aged 2 to 12 years.

Based on proprietary analyses of HAE prevalence and market research studies with HAE patients, physicians, and payors in the United States and Europe, and five full years of commercialization experience with ORLADEYO, we anticipate that the global commercial market for ORLADEYO has the potential to reach a global peak of $1 billion in annual net ORLADEYO revenues. Based on our commercialization experience with ORLADEYO, we believe there is a seasonal impact to our business in the first quarter of each year due to typical first quarter requirements from payors for prescription reauthorization of specialty products, like ORLADEYO, that can temporarily move patients from paid drug to free product. 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 Product 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 I, Item 1A of this report for further discussion of these risks.

Revenue from sales of ORLADEYO in 2025, which was our fifth full year of ORLADEYO sales, 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, but not limited to 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, our pricing strategy, and market trends. We monitor and analyze this data on an ongoing basis as we continue to commercialize ORLADEYO and adjust our forecasts accordingly.

Navenibart (STAR-0215)

On January 23, 2026 (the “Closing Date”), we completed the previously announced Merger (as defined below) with Astria (as defined below). Pursuant to the Merger, on the Closing Date, we acquired Astria’s lead product candidate navenibart, an injectable monoclonal antibody designed to inhibit plasma kallikrein for the treatment of HAE. Navenibart is currently in Phase 3 clinical development, and the FDA has granted Fast Track and Orphan Drug designations to navenibart for the treatment of HAE. In addition, the European Commission has granted Orphan Medicinal Product Designation to navenibart for the treatment of HAE. The goal for navenibart is to develop a potentially best-in-class injectable prophylactic therapy with a differentiated every 3- and 6-month administration schedule, which could offer significant improvements over existing injectable options and address key unmet needs in the HAE patient community.

BCX17725 (Netherton syndrome)

BCX17725 is a potent and selective investigational protein therapeutic KLK5 inhibitor designed to provide best-in-class, potentially disease-modifying, treatment for people with Netherton syndrome. Netherton syndrome is a serious, rare, lifelong genetic disorder causing disruption of the skin barrier with premature separation of the skin layers, chronic inflammation and vulnerability to serious infections, caused by lack of normal function of a natural inhibitor of KLK5. People with Netherton syndrome often have itchy, red, scaly, inflamed skin, fragile hair, and are more likely to develop severe food allergies, asthma and eczema. Netherton syndrome can be life-threatening, especially during infancy when patients are vulnerable to dehydration and recurrent infections. Currently, there are no approved treatments that target the underlying cause of Netherton syndrome. BCX17725 is designed to replace missing functions of the natural KLK5 inhibitor, which could restore the normal skin barrier and result in improved skin function, including protection from severe inflammatory and infectious complications of the disease.

Avoralstat

Avoralstat, an investigational plasma kallikrein inhibitor, is designed to treat patients with diabetic macular edema (“DME”) through the delivery of avoralstat to the back of the eye through the suprachoroidal space. DME is an important cause of vision loss in diabetes and is due to leakage of fluid from the blood vessels in the retina. While current treatments focus on vascular endothelial growth factor (“VEGF”) inhibition, DME can develop from other mechanisms, such as the kallikrein-bradykinin pathway. This is supported by observations that many DME patients have an incomplete response to intravitreal anti-VEGF therapies that are administered every four to eight weeks. Avoralstat targets the kallikrein-bradykinin system on the retinal vascular endothelial cells and may result in less vascular leakage and less edema. Avoralstat, delivered to the suprachoroidal space, is designed to provide long-lasting exposure to the retinal vessels, which

67

could result in less frequent injections and a reduced burden on patients and the healthcare system. We plan to seek a strategic partner for development of avoralstat beyond phase 1.

STAR-0310

Pursuant to the Merger, on the Closing Date, we acquired STAR-0310, which is a monoclonal antibody OX40 antagonist that incorporates YTE half-life extension technology for the treatment of atopic dermatitis (“AD”) and potentially other indications. STAR-0310 was designed as a potentially best-in-class, long-acting OX40 inhibitor with the goal of addressing the need for a safe, effective, and infrequently administered AD treatment. AD is an immune disorder associated with loss of skin barrier function and itching and is caused by diverse mechanisms, spanning the spectrum of T cell-driven pathology. STAR-0310 is currently in a Phase 1a trial to assess the safety, tolerability, pharmacokinetics, and immunogenicity of STAR-0310 in healthy subjects. We plan to seek strategic alternatives for this asset.

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 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 I, 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 primarily on research and development activities, including clinical research activities and the ongoing requirements of our development programs, as well as the costs of commercialization, drug manufacturing, direction from regulatory agencies, and the factors discussed in the “Risk Factors” section in Part I, 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.

Recent Developments

ORLADEYO (berotralstat)

On November 6, 2025, we announced new data demonstrating the early and negative psychosocial impact of HAE and resulting emergency department and hospital visits on pediatric patients and their caregivers, as well as new one-year data from the ongoing APeX-P clinical trial showing early and sustained reductions in monthly attack rates over one year in pediatric patients with HAE aged 2 to 12 years treated with once-daily ORLADEYO.

On December 12, 2025, we announced that the FDA approved our new drug application (“NDA”) for the use of an oral pellet formulation of once-daily ORLADEYO for prophylactic therapy in pediatric patients with HAE aged 2 to 12 years. ORLADEYO is the first and only targeted oral prophylactic therapy for children with HAE aged 2 to 12 years. We also filed an application for the use of ORLADEYO oral pellets in patients with HAE aged 2 to 12 years with the European Medicines Agency and the Japan Pharmaceutical and Medical Devices Agency, and additional regulatory filings are planned in other global territories.

Navenibart (STAR-0215)

On February 26, 2026, we announced that new positive, interim results from the long‑term, open‑label ALPHA‑SOLAR trial show sustained, robust HAE attack suppression with navenibart administered every three and six months.

BCX17725 (Netherton syndrome)

On February 26, 2026, we announced that we expect to report data from the clinical trial of BCX17725 for the treatment of Netherton syndrome in up to 12 patients by the end of 2026.

Avoralstat

On November 3, 2025, we announced that we plan to seek a strategic partner for development of avoralstat beyond phase 1.

Neopharmed Gentili S.p.A. Transaction

As previously disclosed, on June 27, 2025, we entered into a stock purchase agreement (the “Stock Purchase Agreement”) with BioCryst Ireland Limited (“BioCryst Ireland”), a private limited company incorporated under the laws of Ireland and a wholly owned subsidiary of the Company, and Neopharmed Gentili S.p.A., a corporation organized under the laws of Italy (“Neopharmed”). On October 1, 2025 (the “Closing”), under the terms of the Stock Purchase Agreement, we sold to Neopharmed all of our equity interests in BioCryst Ireland, which, together with its subsidiaries, holds certain assets, rights, and employees related to our European ORLADEYO business. At the Closing, we received total cash proceeds of $254.5 million, comprised of the purchase price of $250.0 million and customary purchase price adjustments of $4.5 million as set forth in the Stock Purchase Agreement. In addition, Neopharmed has agreed to pay us up to $14.0 million if certain revenue milestones are achieved prior to December 31, 2032. In connection with the Closing, Neopharmed also paid a $15.0 million royalty release fee to RPI 2019 Intermediate Finance Trust. See “Note 2—Divestiture of BioCryst Ireland Limited” in the Notes to Consolidated Financial Statements in Part II, Item 8 of this report for additional information about the sale of the European ORLADEYO business.

Pharmakon Loan Agreement

On October 8, 2025, we used a portion of the proceeds from the sale of the European ORLADEYO business to pay off in full the outstanding principal balance of $198.7 million and terminate the Pharmakon Loan Agreement (as defined below).

Astria Therapeutics, Inc. Merger

On October 14, 2025, we entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Axel Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of the Company (“Merger Sub”), and Astria Therapeutics, Inc., a Delaware corporation (“Astria”). Pursuant to the Merger Agreement, on the Closing Date, Merger Sub merged with and into Astria, with Astria surviving as a wholly owned subsidiary of the Company (the “Merger”).

Under the terms of the Merger Agreement, at the effective time of the Merger (the “Effective Time”), each share of Astria common stock, par value $0.001 per share, issued and outstanding immediately prior to the Effective Time (excluding shares held by BioCryst, Astria or their wholly owned subsidiaries or dissenting stockholders) was converted into the right to receive (i) 0.59 of a share of the Company’s common stock (and, if applicable, cash in lieu of fractional shares), and (ii) $8.55 in cash, without interest, subject to certain adjustments and applicable withholding taxes. Holders of Astria’s Series X Convertible Preferred Stock, warrants, and certain options were treated as set forth in the Merger Agreement.

Blackstone Loan Agreement

On the Closing Date, we also entered into a Loan Agreement (the “Blackstone Loan Agreement”) with Blackstone Alternative Credit Advisors LP and Blackstone Life Sciences Advisors L.L.C., (together, “Blackstone”), as the Blackstone representatives thereunder, the guarantors from time to time party thereto, the lenders from time to time party thereto, and Wilmington Trust, National Association, as agent, pursuant to which the lenders funded initial term loans in the aggregate principal amount of $400.0 million (the “Term Loans”). Subject to the mutual agreement between the Company,

69

Table of Contents

Blackstone and the lenders, we may request additional term loans up to an aggregate principal amount not exceeding $150.0 million. Our obligations under the Blackstone Loan Agreement are secured by a security interest in, subject to certain exceptions, substantially all of our and our subsidiaries’ assets. We used the proceeds from the Term Loans (i) to pay the cash portion of the consideration required to consummate the Merger and pay other expenses related to the Merger and (ii) to pay the fees, premiums, expenses and other transaction costs incurred in connection with the transactions related to the Merger and the Loan Agreement. The maturity date of the Term Loans under the Loan Agreement is January 23, 2031, the fifth anniversary of the Closing Date. See “Note 21—Subsequent Events” in the Notes to Consolidated Financial Statements in Part II, Item 8 of this report for additional information about the Blackstone Loan Agreement.

Results of Operations

The discussion below presents a summary of our results of operations for fiscal years 2025 and 2024. See Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Results of Operations” of our Annual Report on Form 10-K for the fiscal year ended December 31, 2024, filed with the SEC on February 25, 2025, for a summary of our results of operations for the fiscal year ended December 31, 2023.

Total revenues increased to $874.8 million for the year ended December 31, 2025 compared to $450.7 million for the year ended December 31, 2024. The $424.1 million increase in total revenues was primarily driven by the following:

•$244.0 million increase in license revenue primarily comprised of $243.3 million related to the license of intellectual property to Neopharmed;

•$168.7 million increase in ORLADEYO revenue, excluding revenues associated with our European ORLADEYO business, primarily due to an increase in volume of direct sales of ORLADEYO, which was driven by strong patient demand, an increase in price, and an increase in the rate of paid shipments; and

•$16.0 million increase in other revenue primarily attributed to an increase in direct sales of peramivir.

These increases were partially offset by a $4.5 million decrease in revenues associated with our European ORLADEYO business due to the sale of our European ORLADEYO business to Neopharmed on October 1, 2025.

Research and development expenses

Research and development expenses include all direct and indirect expenses relating to research and development activities. 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 candidates, and 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. Indirect expenses consist of lab supplies and services, facility expenses, depreciation of development equipment and other overhead of our research and development efforts. Research and development expenses vary according to the number of programs in clinical development and the stage of development of our clinical programs. Later stage clinical programs tend to cost more than earlier stage programs due to the longer length of time of the clinical trials and the higher number of patients enrolled in these clinical trials.

We do not maintain or evaluate internal research and development costs on a program-by-program basis. As a result, a significant portion of our research and development expenses are not tracked on a program-by-program basis as the costs may benefit multiple programs. Beginning in the year ended December 31, 2025, we no longer allocate non-program specific external costs or internal costs to programs. These costs are separately presented on the respective line items listed below. Research and development expenses have been reclassified for the year ended December 31, 2024 for comparability. There is no impact on total research and development expenses.

Research and development expenses decreased to $166.1 million for the year ended December 31, 2025 from $174.6 million for the year ended December 31, 2024. The decrease was primarily driven by the following:

71

Table of Contents

•$8.1 million decrease in Factor D Program due to the discontinuation and close-out of the program in 2024;

•$6.1 million decrease in compensation and related personnel costs primarily attributed to a decrease in research and development related headcount net of $2.0 million of expense associated with our December 2025 workforce reduction;

•$4.1 million decrease in other non-program specific and indirect costs primarily attributed to a decrease in the general and administrative expense allocation due to our commercial progression;

•$1.8 million decrease in stock-based compensation expense primarily due to the acceleration of stock-based compensation expense upon adoption of the Retirement Policy (as defined in “Note 13—Stock-Based Compensation” in the Notes to Consolidated Financial Statements in Part II, Item 8 of this report) in July 2024 and a decrease in research and development related headcount, partially offset by an increase in restricted stock unit awards granted; and

•$1.2 million decrease in research and development expenses associated with our European ORLADEYO business (excluding stock-based compensation) due to the sale of our European ORLADEYO business to Neopharmed on October 1, 2025.

These decreases were partially offset by the following:

•$4.9 million increase in BCX17725 primarily due to an increase in manufacturing and clinical operations as we enroll our phase 1 trial in healthy volunteers and patients;

•$4.9 million increase in research, discovery and preclinical programs due to investigational new drug application-enabling activities related to our early-phase pipeline programs;

•$2.0 million increase in avoralstat due to an increase in manufacturing and clinical startup activities; and

•$0.9 million increase in berotralstat primarily attributed to an increase in manufacturing and other costs to support FDA approval in pediatric patients.

Selling, general, and administrative expenses

Sales and marketing expenses include compensation, benefits, and related costs associated with sales and marketing personnel, safety, regulatory, manufacturing, and distribution activities related to marketed products, market research, marketing, medical affairs, market access, and advertising costs. General and administrative expenses include compensation, benefits, and related costs associated with general and administrative personnel, quality activities related to marketed products, finance, human resources, information technology, legal expenses, licenses and other administrative costs, including transaction-related costs.

72

Table of Contents

•$4.9 million increase in manufacturing related costs, including $3.9 million of process development costs;

•$4.9 million increase in compensation and related personnel costs due to the transition of certain regulatory, safety, and manufacturing support roles from research and development to sales and marketing in connection with ORLADEYO’s continued commercial progression;

•$4.7 million increase in compensation and related personnel costs primarily due to compensation increases as a result of strong performance and annual merit increases;

•$2.8 million increase in distribution related costs primarily attributed to increased ORLADEYO sales;

•$1.8 million of expense associated with our December 2025 workforce reduction;

•$0.7 million of transaction-related costs; and

•$11.1 million increase in other sales and marketing expenses, primarily related to costs to support the launch of ORLADEYO in pediatric patients and ORLADEYO commercial growth.

General and administrative expenses (excluding stock-based compensation) increased to $107.9 million for the year ended December 31, 2025 from $70.1 million for the year ended December 31, 2024. The increase was primarily driven by the following:

•$20.4 million of transaction-related costs associated with the sale of our European ORLADEYO business to Neopharmed and the Merger with Astria;

•$11.2 million increase in compensation and related personnel costs primarily due to an increase in compensation and average general and administrative headcount, including $4.4 million due to the transition of certain quality support roles from research and development to general and administrative in connection with ORLADEYO’s continued commercial progression;

•$3.8 million increase due to a change in the allocation of general and administrative expenses to research and development expenses; and

•$2.5 million of expense associated with our December 2025 workforce reduction.

Expenses associated with our European ORLADEYO business (excluding stock-based compensation) decreased to $38.6 million for the year ended December 31, 2025 from $45.3 million for the year ended December 31, 2024 due to the sale of our European ORLADEYO business to Neopharmed on October 1, 2025.

Stock-based compensation expense increased to $55.6 million for the year ended December 31, 2025 from $34.1 million for the year ended December 31, 2024. The increase was primarily due to a modification to extended the post-termination exercise period of certain vested stock option awards at the time of retirement for certain individuals to the original expiration date, resulting in $11.3 million of incremental expense, and an increase in restricted stock unit awards granted.

Other income (expense)

For the year ended December 31, 2025, interest income was $10.7 million compared to $14.7 million for the year ended December 31, 2024. The decrease in interest income was primarily the result of an overall decrease in our average investment portfolio and a decrease in interest rates. Net foreign currency losses were $0.2 million for the year ended December 31, 2025 compared to $0.6 million for the year ended December 31, 2024.

Interest expense for the year ended December 31, 2025 was $78.9 million compared to $98.5 million for the year ended December 31, 2024. Interest expense is primarily comprised of non-cash interest expense due to the amortization of interest associated with the royalty financing obligations and interest expense associated with the borrowings under the Pharmakon Loan Agreement (as defined below), including the amortization of the deferred financing costs, associated with the borrowings under the Pharmakon Loan. The decrease in interest expense was primarily the result of the payoff of the Pharmakon Term Loan in three separate prepayments in 2025 totaling $323.7 million and a decrease in the effective

73

Table of Contents

interest rate during the period in which the debt was outstanding in 2025. In addition, there was a decrease in interest expense associated with our OMERS Royalty Purchase Agreement (as defined in “Note 9—Royalty Financing Obligations” in the Notes to Consolidated Financial Statements in Part II, Item 8 of this report) as result of a lower outstanding principal balance.

For the year ended December 31, 2025, we recognized a one-time loss on extinguishment of debt of $17.3 million as a result of the payoff of the Pharmakon Term Loan.

For the year ended December 31, 2025, other income was $12.1 million, which was primarily comprised of the $4.3 million mark-to-market adjustment on liability classified awards, $3.6 million gain recognized on the sale of BioCryst Ireland to Neopharmed, $2.1 million of pre-close transaction services BioCryst performed on behalf of Neopharmed, and $1.6 million of post-close transition services BioCryst provided to Neopharmed.

Income tax expense

For the year ended December 31, 2025, income tax expense was $3.5 million compared to $1.9 million for the year ended December 31, 2024. The increase in income tax expense was primarily driven by the increase in domestic and foreign taxable income for the year ended December 31, 2025 compared to the year ended December 31, 2024.

Liquidity and Capital Resources

Sources of Liquidity

Our operations have principally been funded through our credit facilities; revenues from ORLADEYO; royalty financing transactions; public offerings and private placements of equity securities; and cash from collaborative and other research and development agreements, including U.S. Government contracts. In addition to the above, we have received funding from other sources, including government grants, research grants, and interest income on our investments.

On the Closing Date, we entered into the Blackstone Loan Agreement, pursuant to which the lenders funded the initial Term Loans in the aggregate principal amount of $400.0 million. We used the proceeds from the Term Loans to pay the cash portion of the consideration required to consummate the Merger. The maturity date of the Term Loans under the Blackstone Loan Agreement is January 23, 2031, the fifth anniversary of the Closing Date. Our obligations under the Blackstone Loan Agreement are secured by a security interest in, subject to certain exceptions, substantially all of our and our subsidiaries’ assets.

The Blackstone 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 our ability and certain of our 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 certain 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 Blackstone Loan Agreement, or an occurrence of any other event of default, could permit the lenders under the Blackstone Loan Agreement to declare the borrowings thereunder, together with accrued interest and fees, and any applicable yield protection premium, to be immediately due and payable. See “Note 21—Subsequent Events” in the Notes to Consolidated Financial Statements in Part II, Item 8 of this report for additional information about the Blackstone Loan Agreement.

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. The Pharmakon Loan Agreement provided for an initial term loan in the principal amount of $300.0 million (the “Tranche A Loan”), which was funded on April 17, 2023. We utilized a portion of the proceeds from the Tranche A Loan to repay the approximate $241.8 million of outstanding indebtedness under the then-existing credit facility with Athyrium Opportunities III Co-Invest 1 LP and to pay transaction costs and fees, and we used the remaining net proceeds of approximately $25.8 million for other general corporate purposes.

The Pharmakon Loan Agreement also provided for three additional term loan tranches in principal amounts of $50.0 million each, which we could have requested, at our option, on or prior to September 30, 2024. We chose not to request any of the additional term loan tranches. The maturity date of the Pharmakon Loan Agreement was April 17, 2028. On April 18, 2025, we made a partial prepayment of $75.0 million of the outstanding principal amount under the Pharmakon Loan

Agreement, and on July 24, 2025, we made an additional partial prepayment of $50.0 million of the outstanding principal amount under the Pharmakon Loan Agreement. On October 8, 2025, we used a portion of the proceeds from the sale of the European ORLADEYO business to pay off in full the outstanding principal balance of $198.7 million and terminate the Pharmakon Loan Agreement.

In 2020 and 2021, we entered into the Royalty Purchase Agreements (as defined in “Note 9—Royalty Financing Obligations” in the Notes to Consolidated Financial Statements in Part II, Item 8 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. Our required payments to OMERS commenced with the calendar quarter beginning October 1, 2023. No royalty payments are due on direct sales over $550.0 million. See “Note 9—Royalty Financing Obligations” in the Notes to Consolidated Financial Statements in Part II, Item 8 of this report for additional information about these financing transactions.

Our principal sources of liquidity at December 31, 2025 were approximately $335.9 million in cash and cash equivalents and available-for-sale investments.

Plan of Operation and Future Funding Requirements

We intend to contain costs and cash flow requirements by closely managing our third-party costs and headcount, leasing scientific equipment and facilities, and contracting with other parties to conduct certain research and development projects. We may incur additional expenses, potentially resulting in significant losses, as we continue to pursue our research and development activities, commercialize ORLADEYO, and engage in strategic business development. 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 or as regulatory exclusivity for our products expires. 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. We invest in marketable debt securities that may consist of U.S. Treasury obligations, U.S government agency securities, money market funds, certificates of deposit, and corporate notes and bonds in order to limit the amount of our credit exposure. We have not realized any significant losses on our investments.

In the future, we may finance our needs principally from the following:

•our existing capital resources and interest earned on that capital;

•revenues from product sales;

•payments under current or future collaborative and licensing agreements with corporate partners;

•lease, royalty, or loan financing; and

•public or private equity and/or debt financing.

Our current and planned clinical trials, plus the related development, manufacturing, regulatory approval process requirements, and additional resources required for the continuing development of our product candidates and the commercialization of our products will consume significant capital resources and could increase our expenses.

Our expenses, revenues and cash utilization rate could vary significantly depending on many factors, including the progress and results of our current and proposed clinical trials for our 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; the overall progression of our other programs; our business development activities; 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 development progress of any collaborative agreements for our product candidates; and the amount and timing of funding we receive, if any, from U.S. Government contracts.

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. Our liquidity needs will be largely determined by the success of operations in regard to the successful commercialization of our products and the future progression of our product candidates. From time to time, we evaluate other opportunities to fund future operations, including: (1) out-licensing rights to certain of our products or product candidates, pursuant to which we would receive cash milestone payments; (2) obtaining additional product candidate regulatory approvals, which would generate revenue, milestone payments and cash flow; (3) reducing spending on one or more research and development programs, including by discontinuing development; (4) restructuring operations to change our overhead structure; and/or (5) securing U.S. Government funding of our programs, including obtaining procurement contracts. We may, in the future, 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 success of our business development efforts; 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:

•sustained market acceptance of approved products and successful commercialization of such products by either us or our partners;

•the progress and magnitude of our research, drug discovery and development programs;

•changes in existing collaborative relationships;

•our ability to establish additional collaborative relationships if and when needed;

•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 NDA filings;

•competitive and technological advances;

•the time and costs involved in obtaining regulatory approvals;

•post-approval commitments for any products that receive regulatory approval;

•our business development activities; 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; 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” in Part I, Item 1A of this report for further discussion of the risks related to obtaining additional capital.

Critical Accounting Estimates

The preparation of these consolidated financial statements in accordance with U.S. GAAP requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues, expenses, and related disclosures for the periods presented. Some of these estimates can be subjective and complex with a significant level of estimation uncertainty, and, consequently, actual results may differ from these estimates. The judgments and assumptions used by management are based on historical experience and information available to us at the time that we make these estimates and judgments. To the extent there are material differences between these estimates and actual results, our consolidated financial statements will be affected. Although we believe that our judgments and estimates are appropriate, actual results may differ from these estimates.

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 II, Item 8 of this report, we believe the following accounting policies to be most critical to the judgments and estimates used in the preparation of our consolidated financial statements.

Revenue Recognition

The application of Accounting Standards Codification (“ASC”) Topic 606 substantially impacts our reported results, particularly product sales, net, which requires certain estimates in determining the transaction price.

Net revenue from sales of ORLADEYO is recorded at net selling price (transaction price), which includes reserves for variable consideration such as (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, representing our best estimates of the amount of consideration to which we are entitled based on the terms of the applicable contracts and statutory requirements, are based on the amounts earned or to be claimed on the related sales and are classified as reductions of accounts receivable if no payments are required of us or a current liability if a payment is required of us. Actual amounts of consideration may differ from our estimates. If actual results vary from estimates, these estimates are adjusted, which would affect net product revenue and earnings in the period such variances become known.

The most subjective of these estimates are government and managed care rebates. We contract with group purchasing organizations associated with managed care organizations and participate in certain government programs 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, 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 contractually mandated discounts applicable to the programs, and (iii) product distribution information obtained from our specialty pharmacy regarding payor mix.

Research and Development Expenses and Related Accruals

As part of the process of preparing our consolidated financial statements, we are required to estimate our accrued research and development expenses. 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 actual work completed 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 periodically confirm the accuracy of our estimates with the service providers and make adjustments if necessary. When evaluating the adequacy of accrued expenses, we consider facts and circumstances known to us at the time, which can include assumptions such as expected patient enrollment, site activation and estimated project duration. Examples of estimated accrued research and development expenses include (i) fees paid to 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 our raw materials, drug substance, drug products, and product candidates, and (iv) professional fees.

The financial terms of our 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 milestones. We record liabilities under these contractual commitments when we determine

an obligation has been incurred, regardless of the timing of the invoice. In expensing 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.

Royalty Financing Obligations

Under the royalty financing obligations, RPI and OMERS are entitled to receive sales-based royalties on net product sales of ORLADEYO. 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 agreements. We impute interest on the carrying values 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 adjustments to the effective interest rates on a prospective basis. The assumptions used in determining the expected repayment terms of the debt and amortization periods 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. 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 future earnings in each of the jurisdictions in which we operate and the period over which our deferred tax assets will be recoverable.

We account for uncertain tax positions in accordance with U.S. GAAP. Uncertain tax positions are recorded based upon certain recognition and measurement criteria. We re-evaluate uncertain tax positions and consider various factors, including, but not limited to, changes in tax law and the measurement of tax positions taken or expected to be taken in tax returns. We adjust the amount of the liability to reflect any subsequent changes in the relevant facts and circumstances surrounding the uncertain tax positions.
