TONDREAU PAMELA L. 4

What Happened

• Pamela L. Tondreau, a director of Energy Recovery, Inc. (ERII), was granted 22,316 restricted stock units (reported as an acquisition) on 2026-06-04. The filing reports an acquisition value of $8.29 per share, totaling $185,000. This was an award (compensation), not an open-market purchase.

Key Details

• Transaction date: 2026-06-04; Filing date: 2026-06-05 (timely; insiders generally must file within two business days).
• Price/value: $8.29 per share; total reported value $185,000.
• Shares acquired: 22,316 restricted stock units (RSUs).
• Vesting/footnote: F1 — the RSUs will fully vest at the 2027 Annual Meeting, anticipated on or around June 3, 2027.
• Shares owned after transaction: not disclosed in the provided filing summary.
• Filing note: Exhibit 24 referenced; no indication of a 10b5-1 plan, tax withholding, or late filing in the provided details.

Context

• These are restricted stock units (future-delivery awards) that generally convert to shares only upon vesting and may be forfeitable until that date, so they represent compensation rather than an immediate market-directional buy.
