WATERTOWN, Mass., March 27, 2026 (GLOBE NEWSWIRE) -- Werewolf Therapeutics, Inc.

“We have initiated a process to explore a range of alternatives available to the Company to maximize stockholder value,” said Daniel J. Hicklin, Ph.D., President and Chief Executive Officer of Werewolf. “Such measures may include, among other options, a sale of the Company, a business combination or merger, a sale of assets, licensing or collaboration arrangements, or other strategic transactions. In addition to our clinical-stage candidates and our named earlier-stage candidates, our INDUKINE and INDUCER platforms provide exciting opportunities to apply our differentiated masking and protease linker technology in multiple additional modalities.”
