Lane Brian E. 4

What Happened Brian E. Lane, CEO of Comfort Systems USA, received awards totaling 5,188 restricted stock units (RSUs) on March 23, 2026 (2,876 and 2,312 shares in two award lines). On the same date, 910 shares were surrendered/withheld to satisfy tax withholding obligations, a disposition reported at a value of $1,281,508 (implied per-share amount $1,408.25). The RSU grants are reported with a $0 acquisition price because they are compensation awards, not open-market purchases.

Key Details

• Transaction date(s): March 23, 2026; Form 4 filed March 25, 2026 (appears timely).

• Withholding/tax: 910 shares disposed (code F) to cover tax liability, reported value $1,281,508 (implied $1,408.25/share).
• Footnotes from the filing:
  • F1: The restricted stock units granted March 23, 2026 vest in equal installments over a three-year schedule (time-based RSUs).
  • F2: The 2023 performance-based (dollar-denominated) RSUs granted March 21, 2023 vested on March 23, 2026 based on the company’s 2023–2025 relative TSR and average EPS performance.

Context

• These transactions are standard executive compensation events: time-based RSU grants and the vesting/settlement of performance RSUs. The F code indicates shares were withheld/surrendered to cover taxes (a common net-share settlement), not an open-market sale.
• No implication about intent or market view should be drawn solely from awards or tax withholdings; awards are part of compensation, and withholding is administrative.
