EMERYVILLE, Calif. - March 18, 2026 (GLOBE NEWSWIRE) - XOMA Royalty Corporation (NASDAQ: XOMA), the biotech royalty aggregator, reported its 2025 fourth quarter and full year financial results and highlighted recent actions that have the potential to deliver additional shareholder value.

"We continue to search for innovative ways to drive enhanced optionality in the XOMA portfolio, with the addition of 22 assets and two platform technologies over the past year," stated Owen Hughes, Chief Executive Officer of XOMA Royalty. "With multiple commercial assets delivering growing royalty receipts, we achieved positive cash flow from operations and were able to return $16 million of capital through a share buyback in 2025. Looking ahead, with 14 programs in registrational studies, we anticipate a number of catalysts over the ensuing years, including several regulatory updates and late-stage clinical readouts in 2026, which, if positive, will further diversify our commercial royalty streams and drive growing free cash flow in 2027 and beyond."

G&A expenses for the years ended December 31, 2025 and 2024, were $36.1 million and $34.5 million, respectively.
