Xeris Biopharma Holdings, Inc. (NASDAQ:XERS), a growth-oriented biopharmaceutical company committed to improving patient lives by developing and commercializing innovative products across a range of therapies, today announced financial results for the fourth quarter and full-year ended December 31, 2023 and recent events.

"2023 was another year of exceptional performance and growth for Xeris. We executed on all fronts: our commercial products grew over 40%; our internal pipeline program, XP-8121, progressed through Phase 2; and our partnership programs made significant advancements, further validating our XeriJect® technology," said Paul R. Edick, Chairman and CEO of Xeris Biopharma. "The momentum continues in 2024 as we expect to grow total revenue in the range of $170 million to $200 million. This double-digit revenue growth, coupled with our recent debt refinancing and continued disciplined cash management, will allow us to further invest in all aspects of our business. We still expect to end 2024 with a very healthy cash position of $55 million to $75 million, demonstrating the sustainability of the company we're building."

Fourth Quarter 2023 Highlights

Commercial Products

• Gvoke®: Fourth quarter 2023 net revenue was $18.6 million as compared to $14.9 million in the fourth quarter of 2022 – an increase of approximately 25%. Gvoke prescriptions topped 59,000 for the first time, growing 43% compared to the same period in 2022. Gvoke's market share of the retail TRx glucagon market grew to over 32% through late February.
• Keveyis®: Fourth quarter net revenue was $14.1 million – an increase of approximately 2% compared to the same period in 2022.
• Recorlev®: Fourth quarter net revenue was $9.8 million – an increase of $6.0 million compared to the same period of 2022. The average number of patients on Recorlev increased over 145% from the same period in 2022.

Pipeline Program

• XeriSol™ levothyroxine (XP-8121): The Phase 2 clinical study has completed enrollment. Data from the Phase 2 study should be available mid-2024.

Technology Partnerships

• XeriJect®: In January, Xeris entered into an exclusive worldwide license agreement for Amgen to develop, manufacture, and commercialize a subcutaneous formulation of teprotumumab using Xeris' XeriJect® technology in Thyroid Eye Disease (TED). Under the terms of the License Agreement, Xeris has the potential to receive $75 million in development, regulatory, and sales-based milestones, as well as escalating single-digit royalties based on future sales of TEPEZZA® using the XeriJect® technology.

Full-year 2023 Financial Results

• Gvoke®: Net revenue was $67.0 million for the full year ended December 31, 2023, a 28% increase compared to prior year. Gvoke prescriptions for the full-year 2023 were over 215,000 prescriptions, growing 48.9% compared to 2022. The growth in product demand was partially offset by a decrease in net pricing.
• Keveyis®: Net revenue was $56.8 million for the full year ended December 31, 2023, a 15% increase from last year. This increase was driven by higher patient demand coupled with an increase in net pricing. This performance exceeds the $40 million revenue milestone that triggered the contingent value rights (CVR) for Strongbridge Biopharma shareholders as record on October 5, 2021. (See Upcoming Events for more details.)
• Recorlev®: Net revenue was $29.5 million for the full year ended December 31,2023, a $22.1 million increase from last year, driven primarily by increases in the number of patients on therapy.

Cost of goods sold increased by $1.3 million for the three months ended December 31, 2023 compared to the same period ended December 31, 2022. The increase was mainly attributable to higher product sales. Cost of goods sold increased by $6.0 million for the full year ended December 31, 2023 compared to the same period ended December 31, 2022. The increase was mainly attributable to higher product sales partially offset by the product mix and a one-time contract credit in the first quarter of 2023.

Research and development expenses increased by $1.4 million for both the three months ended December 31, 2023 and full year compared to the same periods ended December 31, 2022 driven by expenses related to the on-going Phase 2 study of XP-8121.

Selling, general and administrative expenses increased by $3.2 million and $8.4 million for the three and full year ended December 31, 2023, respectively, compared to the same periods ended December 31, 2022, due to higher personnel costs and rent expenses related to the new lease, which commenced in April 2023.

Net Loss was $13.4 million, or $0.10 per share, for the three months ended December 31, 2023 and a net loss of $62.3 million, or $0.45 per share, for the full-year ended December 31, 2023.

Cash, cash equivalents, and short-term investments at December 31, 2023 was $72.5 million compared to $122.0 million at December 31, 2022.

Shares outstanding at February 29, 2024 was 140,453,467.
