Technology Partnerships

• Horizon/Amgen: Xeris successfully formulated the prespecified target product profile of the XeriJecttm formulation of TEPEZZA® which triggered revenue of $6.0 million in the third quarter from a milestone payment under the research collaboration and option agreement with Horizon (subsequently acquired by Amgen) that was signed in November 2022. The payment was subsequently received in the fourth quarter. Amgen has the option to license the XeriJect technology to further the development of an ultra-concentrated, ready-to-use, subcutaneous injection of TEPEZZA®.

Year-to-Date 2023 Financial Results

• Gvoke®: Net revenue was $48.4 million for the nine months ended September 30, 2023, a 29% increase compared to prior year. Gvoke prescriptions for the first three quarters of 2023 were over 156,000 TRx's, growing 51% compared to the same period in 2022. The growth in product demand was partially offset by a decrease in net pricing.
• Keveyis®: Net revenue was $42.7 million for the nine months ended September 30, 2023, a 20% increase from last year. This increase was driven by higher patient demand and an increase in net pricing.
• Recorlev®: Net revenue was $19.7 million for the nine months ended September 30,2023, a $16.1 million increase from last year, driven primarily by increases in the number of patients on therapy.

Cost of goods sold increased by $2.9 million for the three months ended September 30, 2023 compared to the same period ended September 30, 2022. The increase was mainly attributable to higher product sales. Cost of goods sold increased by $4.7 million for the nine months ended September 30, 2023 compared to the same period ended September 30, 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 decreased by $1.0 million for the three months ended September 30, 2023 compared to the same period ended September 30, 2022 driven by lower product development costs.

Selling, general and administrative expenses increased by $2.8 million and $5.1 million for the three and nine months ended 2023, respectively, compared to the same periods ended September 30, 2022, due to higher personnel costs and rent expenses related to the new lease commenced in April 2023.
