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 second quarter and six months ended June 30, 2023 and corporate highlights.

"We posted another record quarter of revenue due to the continued strong demand of all three products, as well as contributions from our partnerships," said Paul R. Edick, Chairman and CEO of Xeris Biopharma. "Our differentiated business model, exceptional year-to-date performance, and expectations for the remainder of the year gives us the confidence to tighten our 2023 guidance by raising the low end of the total revenue range to $145 to $165 million from $135 to $165 million; reducing cash utilization range to $57 to $67 million from $57 to $77 million; improving year-end cash range to $55 to $65 million. And, we expect to be at the cash flow breakeven point in the fourth quarter and continue being a self-sustaining enterprise."

Commercial Products

• Gvoke®: Second quarter 2023 net revenue was $15.6 million as compared to $11.5 million in the second quarter of 2022 – an increase of approximately 36%. Gvoke prescriptions topped 51,000 for the first time, growing 50% compared to the same period in 2022. Gvoke's market share of the retail TRx glucagon market grew to approximately 29% at the end of July.
• Keveyis®: Second quarter net revenue was $14.1 million – an increase of 10% compared to the same period in 2022. The average number of patients on Keveyis increased approximately 11% from the same period in 2022.
• Recorlev®: Second quarter net revenue was $7.2 million – an increase of $6.2 million compared to the second quarter of 2022, the first full quarter since its launch. The average number of patients on Recorlev increased over 400% from the same period in 2022.

Pipeline Program

Year-to-Date 2023 Financial Results

• Gvoke®: Net revenue was $30.7 million for the six months ended June 30, 2023, a 28% increase compared to prior year. Gvoke prescriptions for the first half of 2023 were over 97,000 TRx's, growing 50% 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 $26.8 million for the six months ended June 30, 2023, a 21% increase from last year. This increase was driven by a 9% increase in sales volume and an increase in net pricing.
• Recorlev®: Net revenue was $11.6 million for the six months ended June 30,2023, a $10.5 million increase from last year, driven primarily by increases in the number of patients on therapy.

Cost of goods sold increased by $2.7 million or 57.1% for the three months ended June 30, 2023 compared to the same period ended June 30, 2022. The increase was attributable to higher product sales and product mix. Cost of goods sold increased by $1.8 million or 16.2% for the six months ended June 30, 2023 compared to the same period ended June 30, 2022. The increase was attributable to higher product sales and product mix, partially offset by a one-time contract credit in the first quarter of 2023.

Research and development expenses increased by $2.4 million or 63.7% and $1.0 million or 9.6% for the three and six months ended June 30, 2023, respectively, compared to the same periods ended June 30, 2022. The increases in both periods were due to higher spending on the Open-label Treatment in Cushing's Syndrome (OPTICS) study for Recorlev and higher product development costs.

Selling, general and administrative expenses increased by $4.7 million or 14.1% and $2.3 million or 3.4% for the three and six months ended 2023, respectively, compared to the same periods ended June 30, 2022, due to higher personnel costs, marketing expenses and rent expenses related to the new lease commenced in April 2023.

Net Loss for the three months ended June 30, 2023, was $19.8 million, or $0.14 per share, and a net loss of $36.7 million, or $0.27 per share, for the six months ended June 30, 2023.
