Xeris Biopharma Reports Third Quarter 2026 Financial Results and Business Highlights

Xeris Biopharma Holdings, Inc. (Nasdaq: XERS), a leading endocrine and rare disease biopharmaceutical company committed to helping people realize better lives through the development and commercialization of innovative medicines, today announced its financial results and business highlights for the third quarter ended September 30, 2026.

“As a biopharmaceutical leader in endocrine and rare diseases, our strong third quarter performance puts us on a new growth curve that is accelerating our Company’s near-term outlook, and we are now on a path to reach more than $1 billion in total revenue in 2030,” said John Shannon, Chairman and Chief Executive Officer of Xeris. “This new trajectory reflects growth from the full enterprise. Net product revenue in the third quarter grew more than 43% year-over-year, led by Recorlev, where our expanded commercial team moved from build to yield and delivered record referrals and new patient starts. We now see Recorlev on a path to nearly $1 billion in annual net revenue three to four years sooner than previously expected.”

Shannon continued, “We also continued to advance XP-8121 following our comprehensive program overview in September. We remain on track to initiate Cornerstone, our pivotal Phase 3 study, by year-end. Given the strong momentum across Recorlev, Gvoke, and Keveyis, we are raising our full-year total revenue guidance to $395–$405 million.”

Third Quarter 2026 Highlights

Total revenue for the third quarter of 2026 was $107.2 million, an increase of 44% compared to the same period last year. The increase was primarily driven by increased patient demand for Recorlev. Gvoke delivered stronger-than-historical back-to-school prescription demand in the third quarter, which was offset by a one-time ($4 million) gross-to-net adjustment.

Gross margin improved to 88% in the third quarter of 2026, up from 85% in the same period last year. The improvement was primarily driven by a favorable product mix.

Research and development (R&D) expenses increased by $3.6 million, or 48%, in the third quarter of 2026 compared to the same period last year. The increase in R&D expenses primarily reflects spend to support XP-8121.

Selling, general and administrative (SG&A) expenses increased by $17.6 million, or 38%, in the third quarter of 2026 compared to the same period last year. This increase mainly reflects higher personnel-related expenses to support the commercial enterprise, including the Recorlev expansion.

Net income for the third quarter of 2026 was $11.3 million, compared to net income of $0.6 million in the same period last year.

Adjusted EBITDA¹ for the third quarter of 2026 was $30.8 million, an improvement of $13.3 million compared to the same period last year.

Year-to-Date Highlights (As of September 30, 2026)

Total revenue was $282.5 million for the nine months ended September 30, 2026, an increase of 37% compared to the same period last year. The increase was primarily driven by increased patient demand for Recorlev.

Gross margin improved to 87%, up from 84% in the same period last year. The improvement was primarily driven by favorable product mix.

Research and development (R&D) expenses increased $7.2 million or 31% for the nine months ended September 30, 2026, compared to the same period last year. The increase in R&D expenses primarily reflects spend to support XP-8121.

Selling, general and administrative (SG&A) expenses increased $43.4 million or 32% for the nine months ended September 30, 2026, compared to the same period last year. This increase mainly reflects higher personnel-related expense to support the commercial enterprise, including the Recorlev expansion.

Net loss for the nine months ended September 30, 2026, was $17.6 million, compared to a net loss of $10.5 million in the same period last year. The loss was due to a one-time, non-cash charge of approximately $30.8 million in the second quarter of 2026, reflecting the increase in fair value as a result of entering into the 2028 Convertible Notes exchange agreements.

Adjusted EBITDA¹ for the nine months ended September 30, 2026, was $65.1 million, an improvement of $30.8 million compared to the same period last year.

Total Shares Outstanding were 182,700,038 at October 30, 2026.

The program also includes Capstone, a pediatric study; Touchstone, a study in patients with inconsistent thyroid control despite oral therapy; and a real-world evidence program. Xeris remains on track to initiate Cornerstone by year-end 2026, with topline data expected in late 2028 and potential approval and launch in 2030.

Note Regarding Use of Non-GAAP Financial Measures

This press release includes financial results prepared in accordance with generally accepted accounting principles in the United States (GAAP) and also certain historical 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, less interest and other income, plus depreciation and amortization, interest expense, share-based compensation and debt refinancing fees or extinguishment losses.
