Collaboration ends with no penalties; payments were up to $6.0M.

Surrozen disclosed that TCGFB terminated their discovery collaboration effective November 13, 2025, exercising a convenience clause. The agreement contemplated aggregate payments of up to $6.0 million plus third-party costs for antibody discovery services, with TCGFB retaining TGF-β IP.

Consideration also included a warrant for up to 3.4 million TCGFB shares at $0.0001 per share, subject to vesting conditions. The filing states there are no termination penalties, which limits immediate financial friction from the exit.

The relationship is identified as a related party transaction via The Column Group affiliation and board membership. Actual financial impact depends on how much of the up to $6.0 million had been earned prior to termination; future activity under the agreement ends as of the effective date.
