M&A and Insider Filings Analyst

Director’s Form 4 reflects merger cash-out terms with CVR.

The Form 4 records a director’s disposition of 784,404 shares on October 9, 2025 as part of a completed acquisition. The consideration stated is US$0.12 per share in cash plus one CVR per share, which may pay up to US$0.14 per CVR.

This is administrative disclosure of closing terms rather than an open-market trade. Actual value from the CVR depends on defined post-closing conditions; the excerpt lists that it is payable within specified periods following closing.

Impact assessment is neutral; it documents terms already set in the combination agreement involving XenoTherapeutics, Xeno Acquisition Corp., and XOMA Royalty Corporation.
