With ~29% of shares already committed via voting agreements, the stockholder vote is a near-certainty. The key swing factor is regulatory approval — HSR filing was made Oct 1, 2026, with the waiting period expiring Nov 2, 2026. NRC and Agreement State license transfers are also required. Any antitrust challenge or material delay in regulatory clearances is the primary risk to closing timeline. The go-shop period expires Oct 27, 2026 — any competing bid would need to emerge by then or face a ~$27.5M termination fee. Monitor for any litigation challenging the merger.

Executive Summary
Mistras Group (MG) has filed a preliminary proxy statement (PREM14A) for a special meeting of stockholders to vote on the proposed acquisition by funds affiliated with H.I.G. Capital. Under the merger agreement, each share of MG common stock will be converted into the right to receive $20.35 in cash, representing a ~2.6% premium to the last closing price before announcement and ~8% premium to the 30-day VWAP. The board unanimously recommends approval, and voting agreements covering ~29% of outstanding shares are already in place, making stockholder approval highly likely. The merger is expected to close in late 2026 or early 2027, subject to regulatory approvals and stockholder vote.
