VECTOR SCIENCE AND THERAPEUTICS CORP. SIGNS AMENDED, 10-YEAR MANUFACTURING AND TESTING AGREEMENT WITH LYOGENESIS HOLDINGS

Vector Science and Therapeutics Corp.'s subsidiary, Vector Science and Therapeutics Operating Corp., has entered into an amended and restated exclusive licence and manufacturing agreement, effective Aug. 13, 2026, with LyoGenesis Holdings LLC, amending and restating the parties' prior agreement dated July 6, 2026.

The agreement has an initial term of 10 years, automatically renewing thereafter in successive one-year terms unless terminated earlier in accordance with its terms. LyoGenesis Plus 1 LLC, LyoGenesis's manufacturing subsidiary, continues as VST's exclusive manufacturer of its proprietary, lyophilized peptide-based pharmaceutical products at its facility in Mequon, Wis., in accordance with U.S. current good manufacturing practices. Each batch of products is inspected and approved by the quality assurance function of Verlytix, prior to release to VST.

"This amended agreement gives us a decade of secured, cGMP-compliant manufacturing capacity right here in the United States," said William Jackson, chief executive officer of Vector. "A long-term, dependable supply chain is the foundation for scaling our peptide platform, and this agreement provides exactly that."

"Locking in a stable, decade-long manufacturing relationship with LyoGenesis reflects the kind of long-term planning our shareholders should expect from this team," said Tommy Thompson, chairman of Vector. "A secure, U.S.-based supply chain is foundational to how we intend to scale."

Title to all products is passed onto VST upon delivery. Financial and other commercial terms of the agreement were not disclosed.
