GEORGE MARCUS J 4

What Happened George Marcus J, a director of CECO Environmental Corp. (CECO), was issued equity on June 1, 2026 as part of CECO’s acquisition of Thermon. The Form 4 reports two acquisitions (code A): 36,690 CECO shares (price reported as N/A) and 2,215 CECO shares reported at $0.00. The 36,690 shares were received when Mr. Marcus elected the “Mixed Election Consideration” in the merger, converting his Thermon shares into CECO stock (see footnotes).

Key Details

• Transaction date: June 1, 2026; Form 4 filed June 3, 2026 (appears timely).
• Reported entries: 36,690 shares @ N/A; 2,215 shares @ $0.00 (both acquisition code A).
• Shares vested/vesting: Footnote states shares will vest on May 15, 2027.
• Transaction context: Shares were received as merger consideration under the Agreement and Plan of Merger (Thermon → CECO); not an open‑market buy or sale.
• Shares owned after transaction: Not specified in the filing.

Context These shares arose from the Thermon merger mechanics (the “Mixed Election Consideration” option detailed in the filing), not from a voluntary market purchase or sale. Because some or all of the issuance vests in the future, the shares may be restricted until May 15, 2027. This is an acquisition-type insider report (A) reflecting merger consideration rather than an indicator of open-market buying or selling.
