Otter Tail (OTTR) Sr VP John S. Abbott Receives Performance Shares

What Happened

John S. Abbott, Senior Vice President, Manufacturing Platform at Otter Tail Corporation, received 8,400 performance shares that vested on 2026-02-11 at a reported value of $86.43/share (total $726,012). To cover tax withholding on the vesting, 4,209 shares were withheld (treated as a disposition) valued at $86.43/share ($363,784). That results in a net increase of 4,191 shares (about $362K at $86.43). Separately, on 2026-02-10 he was granted 1,600 restricted stock units (RSUs) (reported at $0 as a derivative grant).

Key Details

Transaction dates and values:
- 2026-02-11: Performance shares vested — 8,400 shares @ $86.43 = $726,012 (acquired).
- 2026-02-11: Tax withholding — 4,209 shares @ $86.43 = $363,784 (disposed to cover taxes).
- 2026-02-10: Grant of 1,600 RSUs (derivative grant reported at $0).
Net shares acquired from the vesting: 4,191 shares (≈ $362K at $86.43).
Shares owned after transaction: not specified in the provided filing data.
Relevant footnotes:
- F1: Vesting reflects performance share award originally granted in 2023.
- F2: Withheld shares were surrendered to the company to pay taxes; this withholding is exempt under Rule 16b-3(e).
- F4/F5: Each RSU equals a contingent right to one share; RSUs vest in four equal annual installments beginning on the date shown.
- F3: Total direct holdings include shares from Restricted Stock and Performance Share awards.
Filing timeliness: Form 4 filed 2026-02-12 reporting activity through 2026-02-10/02-11 — appears timely (not marked late).

Context

This activity is company-issued compensation (vesting of performance shares and a grant of RSUs), not an open-market buy or sale. Withholding shares to cover taxes is a routine administrative step and should not be read as an independent sale signal.
The RSU grant is a future-contingent award (one RSU = one share when vested) that vests in four equal annual installments, so additional shares may be delivered over coming years if vesting conditions are met.
