Catalyst Pharmaceuticals (CPRX) CFO Michael Kalb Sells Shares in Merger

What Happened
Michael Wayne Kalb, Chief Financial Officer of Catalyst Pharmaceuticals (CPRX), disposed of company securities in connection with the closing of the company’s acquisition by Angelini Pharma S.p.A. On July 15, 2026 he surrendered 13,665 common shares at $31.50 per share for gross proceeds of $430,448. In addition, a total of 632,903 option/RSU-equivalent awards were cancelled/converted (reported at $0 per share because they were cash-settled under the merger terms).

  • Total shares/equivalents affected: 646,568 (13,665 common shares + 632,903 options/RSUs).
  • Footnotes: (F1–F5) disclose that the dispositions were made in connection with the Merger; RSUs/options vested on closing and were cancelled and converted into cash payments calculated under the merger (cash payments are net of tax withholdings).

Context
These were disposals to the issuer as part of the acquisition closing, not open‑market sales. Options and restricted stock units vested at closing and were converted into cash payments per the merger agreement (i.e., cancelled and cashed out). Such merger-related cash settlements are routine corporate‑transaction outcomes and reflect the deal mechanics rather than an independent trading decision by the insider.
