TARRYTOWN, N.Y., April 29, 2026 (GLOBE NEWSWIRE) -- Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) today announced financial results for the first quarter of 2026 and provided a business update.

"In the first quarter of this year, we were able to achieve strong double-digit growth on both the top and bottom line while continuing to invest significant resources in our portfolio of nearly 50 product candidates in clinical development," said Leonard S. Schleifer, M.D., Ph.D., Board co-Chair, President and Chief Executive Officer of Regeneron. "Additionally, we recently entered into an agreement with the U.S. government that aims to make progress toward lowering drug prices for American patients by promoting more balanced pricing with other wealthy nations — an approach for which Regeneron has long advocated."

"Regeneron delivered strong first quarter 2026 financial results, achieving total revenue and non‑GAAP net income per share growth of 19% and 15%, respectively," said Christopher Fenimore, Executive Vice President, Finance and Chief Financial Officer of Regeneron. "In addition to driving commercial execution, we remain focused on our balanced approach to capital allocation—investing in our internal innovation engine, returning capital to shareholders through dividends and share repurchases, expanding our R&D and manufacturing footprint to support long-term growth, and preserving financial flexibility to pursue strategic business development opportunities."

Business Highlights

Key Pipeline Progress
Regeneron has nearly 50 product candidates in clinical development, including a number of marketed products for which it is investigating additional indications. Updates from the clinical pipeline include:

Dupixent (dupilumab)

In April 2026, the U.S. Food and Drug Administration (FDA) and European Commission approved Dupixent for the treatment of CSU in children aged 2 to 11 years who remain symptomatic despite antihistamine treatment. This expands the previous approvals in the United States and European Union (EU) for CSU in adults and adolescents aged 12 years and older.
In March 2026, the Ministry of Health, Labour and Welfare (MHLW) in Japan approved Dupixent for the treatment of adults with moderate-to-severe bullous pemphigoid (BP). Dupixent was previously approved for the treatment of BP in the United States and a regulatory application is under review in the EU.
In February 2026, the FDA approved Dupixent as the first and only medicine for the treatment of adults and children aged 6 years and older with AFRS.

EYLEA HD (aflibercept) 8 mg

In April 2026, the FDA approved the extension of dosing intervals for EYLEA HD up to every 20 weeks (5 months) for patients with wAMD and DME following one year of successful response based on visual and anatomic outcomes. This further extends the widest range of dosing intervals of any approved injectable anti-VEGF product.
The Company resubmitted its application seeking FDA approval for filling of the EYLEA HD pre-filled syringe (PFS) at Catalent Indiana, where the FDA has recently conducted a site re-inspection. In addition, the FDA did not act by the April 2026 PDUFA date on the Company's regulatory application for a second contract manufacturer for the PFS; therefore, this application remains pending. The Company and both third-party filling manufacturers are working closely with the FDA to resolve all outstanding issues, and the Company anticipates a regulatory decision on one or both applications during the second quarter of 2026.

Otarmeni (lunsotogene parvec)

In April 2026, the FDA granted accelerated approval for Otarmeni (lunsotogene parvec, formerly known as DB-OTO), the first gene therapy approved under the FDA Commissioner’s National Priority Voucher program. Otarmeni is an adeno-associated virus vector-based gene therapy indicated for the treatment of pediatric and adult patients with severe-to-profound hearing loss associated with variants in the OTOF gene. Otarmeni is the first and only in vivo gene therapy for genetic hearing loss and will be made available by Regeneron for free in the United States.

Fianlimab (LAG-3 antibody)

The Company remains on track to report results from the Phase 3 study of fianlimab in combination with cemiplimab versus pembrolizumab in first-line metastatic melanoma in the second quarter of 2026.
Following the first interim analysis, an Independent Data Monitoring Committee recommended that the Phase 3 study of fianlimab in combination with cemiplimab in adjuvant melanoma continue as planned. A second interim analysis as well as the study's final analysis, if necessary, are anticipated in the second half of 2026. Regeneron remains blinded to these data.
The Company determined that Phase 2 data evaluating fianlimab in combination with cemiplimab in first-line advanced non-small cell lung cancer (NSCLC) did not support advancement to Phase 3 development.

Other Programs

The Company submitted a New Drug Application (NDA) for cemdisiran (C5 siRNA therapy) in myasthenia gravis, and utilized an FDA Rare Pediatric Disease Priority Review Voucher. NDA acceptance is anticipated in the second quarter of 2026 with an FDA decision expected in the fourth quarter of 2026.
In February 2026, the FDA accepted for priority review the Biologics License Application (BLA) for garetosmab (an Activin A antibody) for the treatment of adults with fibrodysplasia ossificans progressiva (FOP), which has a target action date in August 2026. A regulatory application is also under review in the EU.
A Phase 3 study for REGN7508, an antibody to Factor XI (catalytic domain), was initiated in cancer-associated venous thromboembolism. In addition, a three-arm, placebo-controlled Phase 3 study was initiated to evaluate REGN7508 and REGN9933, an antibody to Factor XI (A2 domain), individually, in stroke prevention in patients with atrial fibrillation who are not candidates for daily oral anticoagulation therapy. Initiation of additional Phase 3 studies for these Factor XI antibodies is planned for later this year.
A Phase 3 study was initiated for mibavademab, an agonist antibody to leptin receptor (LEPR), in monogenic obesity.

Corporate Updates

In April 2026, the Company announced agreements with the U.S. government pursuant to which the Company will provide certain of its products to the Medicaid program at or below prices benchmarked against a defined group of other developed countries (Most-Favored-Nation Pricing), price certain future medicines in the United States at or below Most-Favored-Nation Pricing, offer Praluent^® for direct patient purchase, and continue its large investment in domestic R&D and manufacturing capacity. Furthermore, Regeneron will not be subject to future U.S. government pricing mandates and will receive tariff relief for three years.
In March 2026, the Company entered into a strategic collaboration with TriNetX to receive access to TriNetX’s current and future de-identified health data from approximately 300 million individuals, sourced directly from its global network of health system partners. This collaboration will enable expansion of the Company’s genomic and proteomic Electronic Health Record (EHR)-linked database.
In April 2026, the Company entered into a collaboration with Telix Pharmaceuticals Limited to jointly develop and commercialize next generation radiopharmaceutical therapies.
In February 2026, the Company announced the renewal of Regeneron’s title sponsorship of the Regeneron Science Talent Search (STS), the United States’ oldest and most prestigious science and mathematics competition for high school seniors. The Company is also increasing its commitment for the next 10 years, pledging an additional $150 million, and bringing its 20-year investment in STS to $250 million.
In February 2026, the Company reached resolution of its patent infringement litigation related to the Samsung EYLEA (aflibercept) Injection 2 mg biosimilar product. This settlement precludes Samsung from launching its biosimilar product in the United States until January 2027. All intellectual property-related litigation with Samsung in the United States has been dismissed.

** Percentage not meaningful

Net product sales of EYLEA HD increased in the first quarter of 2026, compared to the first quarter of 2025, due to higher sales volumes driven by increased demand, partly offset by a lower net selling price. In addition, EYLEA HD net product sales were negatively impacted by lower wholesaler inventory levels at the end of the first quarter of 2026 compared to the end of the fourth quarter of 2025. EYLEA HD net product sales decreased 7% on a sequential basis; however, physician unit demand increased sequentially by 10%.

Net product sales of EYLEA in the first quarter of 2026, compared to the first quarter of 2025, were negatively impacted by (i) lower sales volumes as a result of continued competitive pressures and the continued transition of patients to EYLEA HD, and (ii) a lower net selling price.

Sanofi collaboration revenue increased in the first quarter of 2026, compared to the first quarter of 2025, due to an increase in the Company's share of profits from the commercialization of antibodies, which were $1.451 billion and $1.018 billion in the first quarter of 2026 and 2025, respectively. The change in the Company's share of profits from commercialization of antibodies was driven by higher profits primarily associated with an increase in Dupixent sales.

* GAAP and non-GAAP amounts are equivalent as no non-GAAP adjustments have been recorded
** Percentage not meaningful

GAAP and non-GAAP R&D expenses increased in the first quarter of 2026, compared to the first quarter of 2025, driven by the advancement of the Company's late-stage clinical pipeline, including programs in hematology-oncology, complement-mediated diseases, and anticoagulation.
Acquired IPR&D expenses for the first quarter of 2026 primarily related to the premium on equity securities purchased, as well as development milestone and up-front payments, in connection with collaboration and licensing agreements.
GAAP and non-GAAP SG&A expenses increased in the first quarter of 2026, compared to the first quarter of 2025, primarily due to an increase in commercialization-related expenses for EYLEA HD and Libtayo and higher headcount and headcount-related costs, partly offset by lower charitable contributions to an independent non-profit patient assistance organization.
GAAP gross margin on net product sales decreased in the first quarter of 2026, compared to the first quarter of 2025, primarily due to unabsorbed manufacturing costs and higher inventory write-offs and reserves as a result of a temporary interruption of bulk manufacturing production at the Company's facility in Limerick, Ireland, due to unanticipated facility repairs that commenced during the first quarter of 2026. The Company resumed initial production at the facility in the second quarter of 2026; however, GAAP gross margin will continue to be negatively impacted until production returns to normal levels, which is expected by the end of the second quarter of 2026. The interruption has not impacted, nor is it expected to impact, the availability of any of the Company's products.

Other Financial Information

GAAP other income (expense), net decreased in the first quarter of 2026, compared to the first quarter of 2025, primarily due to lower net gains on marketable and other securities.

In the first quarter of 2026, the Company's GAAP effective tax rate (ETR) was 12.5%, compared to 10.6% in the first quarter of 2025. The GAAP ETR increased in the first quarter of 2026, compared to the first quarter of 2025, primarily due to lower tax benefits from cross-border tax laws and federal tax credits for research activities. In the first quarter of 2026, the non-GAAP ETR was 13.9%, compared to 11.6% in the first quarter of 2025.

A reconciliation of the Company's GAAP to non-GAAP results is included in Table 3 of this press release.

Capital Allocation

During the first quarter of 2026, the Company repurchased $803 million of its common stock. As of March 31, 2026, $688 million remained available for share repurchases under the Company's share repurchase programs. In April 2026, the Company's board of directors authorized a new share repurchase program to repurchase up to an additional $3.0 billion of the Company's common stock. Repurchases may be made from time to time at management's discretion through a variety of methods. The program has no time limit and can be discontinued at any time.

In April 2026, the Company's board of directors declared a cash dividend of $0.94 per share on the Company's common stock and Class A stock, payable on June 4, 2026 to shareholders of record as of May 20, 2026.

^(a)	This press release uses non-GAAP R&D, non-GAAP SG&A, non-GAAP COGS, non-GAAP gross margin on net product sales, non-GAAP COCM, non-GAAP other income (expense), net, non-GAAP ETR, non-GAAP net income, non-GAAP net income per share, and free cash flow, which are financial measures that are not calculated in accordance with U.S. Generally Accepted Accounting Principles (GAAP). These non-GAAP financial measures are computed by excluding certain non-cash and/or other items from the related GAAP financial measure. The Company also includes a non-GAAP adjustment for the estimated income tax effect of reconciling items. A reconciliation of the Company's GAAP to non-GAAP results is included in Table 3 of this press release. The Company makes such adjustments for items the Company does not view as useful in evaluating its operating performance. For example, adjustments may be made for items that fluctuate from period to period based on factors that are not within the Company's control (such as the Company's stock price on the dates share-based grants are issued or changes in the fair value of the Company's investments in equity securities) or items that are not associated with normal, recurring operations (such as acquisition and integration costs). Management uses these non-GAAP measures for planning, budgeting, forecasting, assessing historical performance, and making financial and operational decisions, and also provides forecasts to investors on this basis. With respect to free cash flow, the Company believes that this non-GAAP measure provides a further measure of the Company's ability to generate cash flows from its operations. Additionally, the non-GAAP measures presented are intended to provide investors with an enhanced understanding of the financial performance of the Company's core business operations. However, there are limitations in the use of these and other non-GAAP financial measures as they exclude certain expenses that are recurring in nature. Furthermore, the Company's non-GAAP financial measures may not be comparable with non-GAAP information provided by other companies. Any non-GAAP financial measure presented by the Company should be considered supplemental to, and not a substitute for, measures of financial performance prepared in accordance with GAAP.

^(b)	Gross margin on net product sales represents gross profit expressed as a percentage of total net product sales recorded by the Company. Gross profit is calculated as net product sales less cost of goods sold.

^(c)	Corresponding reimbursements from collaborators and others for manufacturing product is recorded within revenues.
