Unitil (UTL) CAO Todd R. Diggins Receives Award
What Happened
- Todd R. Diggins, Chief Accounting Officer & Controller of Unitil Corporation (UTL), reported multiple equity acquisitions on January 27, 2026. He acquired a total of 2,710 shares: 1,080 shares (grant), another 1,080 shares (grant), 10 shares purchased at $50.00 each ($500 total), and 540 shares reported as a derivative award (value N/A).
- These transactions are acquisitions/awards (not open-market sales). The small 10-share purchase is a direct buy; the larger amounts are stock plan grants or contingent/performance awards and are typically not an immediate market purchase signal.
Key Details
- Transaction date: January 27, 2026; Form filed January 29, 2026 (appears timely).

- F2/F5: Some shares are contingent on a three‑year performance period and vest based on performance thresholds.
- F3: One grant reflects the conclusion of the 2023–2025 performance period; contingent balance for that period terminated.
- F4: historical dividend reinvestment share purchases are noted elsewhere in filing history.
- Filing timeliness: Filed Jan 29 for Jan 27 transactions — within the typical two-business-day Form 4 window.
Context
- Most shares here are awards subject to vesting or performance conditions; such grants are standard compensation and do not necessarily reflect immediate insider sentiment. The 10-share purchase ($500) is a small open-market buy. The 540-share derivative entry represents contingent/performance-based award treatment rather than an exercised option or gift.
