CHICAGO / May 09, 2023 / Business Wire / Xeris Biopharma Holdings, Inc. (Nasdaq: XERS), a growth-oriented biopharmaceutical company committed to improving patients’ lives by developing and commercializing innovative products across a range of therapies, today announced financial results for the first quarter ended March 31, 2023, and other corporate highlights.

“We had a very strong start to 2023 with record total revenue, strong underlying patient demand in all three commercial products, and the addition of another XeriJect collaboration,” said Paul R. Edick, Chairman and CEO of Xeris Biopharma. “With continued steady and strong execution, we believe that we can achieve our 2023 revenue and year-end cash guidance and achieve cash flow breakeven in the fourth quarter this year.”

First Quarter Highlights and Recent Events

Commercial Products

• Gvoke®: First quarter net revenue was $15.0 million as compared to $12.5 million in the first quarter of 2022, an increase of approximately 21%. Gvoke prescriptions topped 45,000 for the first time, growing approximately 50% compared to the same period in 2022. Year over year glucagon TRx and NRx market growth was 10% and 9%, respectively. At the end of April, Gvoke’s NRx and TRx market share of the retail glucagon market exceeded 30% and 29%, respectively. In the first quarter, the U.S. Patent and Trademark Office issued US Patent Number 11,590,205, entitled ‘METHODS FOR PRODUCING STABLE THERAPEUTIC GLUCAGON FORMULATIONS IN APROTIC POLAR SOLVENTS.’ The claims in this newly issued patent cover certain pharmaceutical formulations in Xeris’ Gvoke® product line, methods of use of such formulations in treating hypoglycemia, and methods of manufacturing the therapeutic formulations.
• Keveyis®: First quarter net revenue was $12.8 million, an increase of approximately 37% compared to the same period in 2022, driven by higher patient demand.
• Recorlev®: First quarter net revenue was $4.5 million driven primarily by increases in the number of patients on therapy.

• XeriJect®: In March, Xeris announced a research collaboration and option agreement with Regeneron to develop an ultra-concentrated, ultra-highly concentrated, ready-to-use, small volume subcutaneous injections of two undisclosed monoclonal antibodies developed by Regeneron.

First Quarter 2023 Other Results

Cost of goods sold was $5.3 million and $6.3 million for the three months ended March 31, 2023 and 2022, respectively. The decrease was attributable to a one-time contract credit and favorable product mix offset by an increase in product sales.

Research and development expenses decreased $1.4 million for the three months ended March 31, 2023 when compared to the same period in 2022. The decrease was primarily driven by lower product development costs in the period.

Selling, general and administrative expenses decreased $2.3 million for the three months ended March 31, 2023 when compared to the same period in 2022. The decrease was primarily driven by lower costs related to the restructuring plan commenced in 2021 and fully expensed by 2022.

Net Loss for the three months ended March 31, 2023, was $16.8 million, or $0.12 per share.

Cash, cash equivalents, and short-term investments at March 31, 2023 was $95.1 million compared to $122.0 million at December 31, 2022. Total shares outstanding at May 1, 2023, were 137,311,468.
