Buntin David 4

What Happened

• David Buntin, Senior VP, Products & Technology at Thermon Group Holdings (THR), had two merger-related transactions on 2026-06-01: a disposition of 99,767 THR shares to the issuer (conversion in the CECO merger) and an acquisition/award of 19,386 shares (PU-related conversion). Prices are listed as N/A on the Form 4 because the THR shares were converted under the merger terms rather than sold on the open market.
• Per the Merger Agreement, Buntin elected the "mixed consideration" for converted THR shares (0.6840 CECO shares + $10.00 cash per THR share). The 19,386 PU shares were converted into CECO restricted stock units (CECO RSUs) and are no longer subject to performance vesting (they carry the original time‑based vesting/forfeiture terms).

Key Details

• Transaction date: 2026-06-01; Form 4 filed 2026-06-03 (timely filing).
• Actions: D (Disposition to issuer) — 99,767 THR shares; A (Award/Acquisition) — 19,386 shares (PU conversion). Prices reported as N/A because consideration was provided per merger terms.
• Reporting person elected mixed consideration (0.6840 CECO shares + $10.00 cash) for converted THR shares.
• Footnotes: merger closed under Agreement and Plan of Merger (F1); PU awards vested/converted per merger terms (F2, F3, F6); RSUs converted to CECO RSUs (F5).
• Shares owned after transaction: not specified on the Form 4 (converted/assumed awards now reflected as CECO RSUs).

Context

• These transactions are merger-related conversions, not open-market buys or sales. Disposition to the issuer means THR shares were exchanged under the merger formula for cash and/or CECO stock rather than sold on the public market.
• The 19,386 PU-derived awards were converted into CECO RSUs and lost their performance-based vesting (they remain subject to any time-based vesting/forfeiture). Such corporate-merger conversions are administrative and do not necessarily indicate insider sentiment about future performance.
