Grubb David Harold Jr. 4

What Happened
David Harold Grubb Jr., Chief Commercial Officer of SOLV Energy (MWH), had 235,947 MH Units (derivative interests) automatically redeemed for cash on 2026-06-01 in connection with a follow-on offering. The redemption price was $36.00 per unit (the public offering price net of underwriting discounts), for a total cash amount of $8,494,092 (235,947 × $36.00). This was a non-discretionary, pro rata redemption rather than an open-market sale by the insider.

Key Details

• Transaction date: 2026-06-01; Form 4 filed: 2026-06-03 (appears timely within the usual 2-business-day window).
• Instrument/Code: Disposition to issuer (D) — derivative units (MH Units) redeemed for cash.
• Units disposed/redeemed: 235,947 MH Units.
• Price per unit: $36.00 (public offering price net of underwriting discounts).
• Total realized: $8,494,092.
• Post-transaction holdings: not specified in the Form 4.
• Notable footnotes: redemption triggered by the Limited Partnership Agreement and LLC agreement; redemption also resulted in surrender/cancellation of corresponding Class B common stock held by the affiliate (MH) and cancellation of MH Units held by the reporting person. The transaction was automatic and required by the partnership agreements in connection with the follow-on offering by affiliates of American Securities LLC and the issuer.

Context: This was an automatic, contractual redemption tied to a company follow-on offering—i.e., a corporate/partnership mechanics-driven disposition—not an opportunistic open-market sale by the insider. Such mandated redemptions are typically routine and reflect agreement terms rather than a decision about the company’s prospects.
