Lexicon Pharmaceuticals Announces $100 Million Loan Facility with Hercules Capital

THE WOODLANDS, Texas, May 04, 2026 (GLOBE NEWSWIRE) -- Lexicon Pharmaceuticals, Inc. (NASDAQ:LXRX) announced today that it has entered into a loan facility with Hercules Capital, Inc. (NYSE:HTGC) that provides up to $100 million in borrowing capacity. Access to this non-dilutive capital provides Lexicon with greater financial flexibility through both an extended interest-only period and maturity date and the opportunity to further strengthen its balance sheet to support pivotal upcoming regulatory and commercial milestones.

"Operational excellence, financial discipline and financial flexibility are key pillars of our corporate strategy for long-term growth," said Scott Coiante, Lexicon's chief financial officer. "By refinancing our existing loan facility with Hercules Capital, a strong partner with a history of supporting biotech innovation, we are expanding our access to non-dilutive capital and gaining additional flexibility to opportunistically deploy capital on value-creating initiatives, including the advancement of our pipeline of late-stage cardiometabolic programs."

"Hercules Capital is pleased to support Lexicon Pharmaceuticals with a flexible financing solution that will support it through upcoming clinical and regulatory milestones," said Adam Soller, Managing Director. "This partnership underscores our commitment to funding innovative therapies that address significant unmet medical needs."

Under the terms of the agreement, the initial $55 million tranche was funded at closing and will be used to repay Lexicon's existing loan facility with Oxford Finance. The second $20 million tranche is available for draw at Lexicon's option subject to the achievement of certain clinical, regulatory and financial milestones and specified timing requirements. The third $25 million tranche is available for draw at Lexicon's option following its draw of the second tranche and subject to Hercules' consent and specified timing requirements.

The loan facility carries a floating interest rate equal to the prime rate plus 3.1%, with a floor not less than 9.85%. The loan facility provides for an initial interest-only period of 18 months, with the potential for two six-month extensions. The outstanding principal amount and all accrued but unpaid interest shall be repaid on or before May 4, 2030.

Lexicon's obligations under the loan facility are secured by a first lien security interest in all of Lexicon's assets and are subject to customary covenants, including a minimum cash covenant beginning on June 1, 2027, subject to extension upon the achievement of certain clinical and financial milestones and waiver upon the achievement of certain financial conditions.
