CHICAGO, IL (BUSINESS WIRE); November 6, 2025 – Xeris Biopharma Holdings, Inc. (Nasdaq: XERS), a fast-growing biopharmaceutical company committed to improving patient lives by developing and commercializing innovative products across a range of therapies, today announced financial results for the third quarter ended September 30, 2025.

“We delivered another record-breaking quarter, driven by increased patient demand across all three products,” said John Shannon, Chief Executive Officer. “Total product revenue grew 40% year-over-year, highlighting the strength of our portfolio and the meaningful difference we’re making in the lives of patients and providers alike. Recorlev led the way, with revenue growing 109% to $37 million, further validating its significant growth potential."

Shannon continued, "Our year-to-date performance underscores the strength of our growth engine and the effectiveness of our strategic execution. With momentum continuing to build across the business, we are updating our 2025 total revenue guidance to $285-$290 million, which implies 42% growth at the midpoint compared to last year. As we progress through the final quarter, our focus remains on executing and investing in opportunities that will propel sustained growth into 2026 and beyond."

•Recorlev® net revenue was $37.0 million – an increase of approximately 109% compared to the third quarter of 2024. This growth was due to increased patient demand.

•Gvoke® net revenue was $25.2 million – an increase of approximately 10% compared to the third quarter of 2024. The increase was due to higher volume and favorable net pricing.

•Keveyis® net revenue was $11.9 million – a decrease of approximately 2% compared to the third quarter of 2024.

Cost of goods sold (COGS) decreased $2.6 million or 19% in the third quarter of 2025 compared to the same period last year. This improvement was primarily due to a reduction of Gvoke inventory write-offs in 2025.

Research and development (R&D) expenses increased $1.6 million or 27% in the third quarter of 2025 compared to the same period last year. The increase in R&D expenses primarily reflects personnel-related expenses to support both XP-8121 and the ongoing development of the Company's technology platforms and partnerships.

Selling, general and administrative (SG&A) expenses increased $1.5 million or 3% in the third quarter of 2025 compared to the same period last year. This increase mainly reflects incremental personnel related expenses.

Net income for the third quarter was $0.6 million, compared to a net loss of $15.7 million in the same period last year.

Adjusted EBITDA1 for the third quarter was $17.4 million, an improvement of $20.1 million compared to the third quarter of 2024.

•Recorlev® net revenue was $94.0 million - an increase of approximately 126% compared to the nine months ended September 30, 2024. This growth was due to increased patient demand.

•Gvoke® net revenue was $69.5 million - an increase of approximately 17% compared to the nine months ended September 30, 2024. The increase was due to higher volume and favorable net pricing.

•Keveyis® net revenue was $34.9 million - a decrease of approximately 9% compared to the nine months ended September 30, 2024. The decrease was due to unfavorable net pricing, partially offset by higher volume.

•Other product revenue increased by $1.3 million for the nine months ended September 30, 2025. This includes the sale of Gvoke VialDx units to American Regent.

•Royalty, contract and other revenue was $6.5 million and primarily reflects the recognition of milestones for Gvoke VialDxTM.

Cost of goods sold (COGS) increased $4.3 million or 16% for the nine months ended September 30, 2025, compared to the same period in 2024. This increase was primarily due to an increase in product revenue.

Research and development (R&D) expenses increased $3.8 million or 20% for the nine months ended September 30, 2025, compared to the same period last year. The increase in R&D expenses primarily reflects personnel-related expenses to support both XP-8121 and ongoing development of the Company's technology platforms and partnerships.

Selling, general and administrative (SG&A) expenses increased $11.5 million or 9% for the nine months ended September 30, 2025 compared to the same period last year. The increase mainly reflects higher personnel related expense ($7.9 million), largely due to investments made in the Recorlev commercial organization starting in the third quarter of 2024.

Net loss for the nine months ending September 30, 2025, was $10.5 million or ($0.07) per share, compared to a net loss of $49.7 million or ($0.34) per share in the prior year period. This represents a 79% improvement versus the prior year period.

This press release includes financial results prepared in accordance with generally accepted accounting principles in the United States (GAAP) and also certain historical and forward-looking non-GAAP financial measures, namely Adjusted EBITDA. This non-GAAP financial measure is not meant to be considered in isolation and should be read in conjunction with the Company's consolidated financial statements prepared in accordance with GAAP, and was not prepared under any comprehensive set of accounting rules or principles. Non-GAAP financial measures are not an alternative for financial measures prepared in accordance with GAAP, and the calculation of the non-GAAP financial measure included herein may differ from similarly titled measures used by other companies. The Company believes that the presentation of Adjusted EBITDA, when viewed in conjunction with actual GAAP results, provides investors with a more meaningful understanding of the Company's ongoing and projected operating performance, exclusive of factors that do not directly affect what the Company considers to be its core operating performance, as well as unusual events. The Company believes this non-GAAP financial measure helps indicate underlying trends in the Company’s business and is important in comparing current results with prior period results and understanding expected operating performance. Also, management uses this non-GAAP financial measure to establish budgets and operational goals, and to manage the Company’s business and evaluate its performance. In addition, management believes that Adjusted EBITDA is important in evaluating the administrative costs of operating the Company’s business.

Adjusted EBITDA is GAAP net income (loss) before income tax (benefit) expense, plus interest and other income, less depreciation and amortization, interest expenses, share based compensation and debt refinancing fees.
