CUTILLO JOSEPH A 4

What Happened
Joseph A. Cutillo, a director of NPK International Inc. (NPKI), received an award of 8,558 shares on 2026-05-20. The filing reports the acquisition price as $0 (award/grant code A). This was an equity grant—not a purchase or sale—so it does not represent a market trade.

Key Details

• Transaction date: 2026-05-20; Form 4 filed: 2026-05-21 (timely filing).
• Shares granted: 8,558; reported acquisition price: $0; total cash value not reported in the filing.
• Vesting: The shares vest on the earlier of the first anniversary of the grant date or the day prior to the next annual stockholders meeting (per footnote).
• Shares owned after the transaction: not specified in the provided filing.
• Transaction type/code: A = Award/Grant. No 10b5-1 plan, tax-withholding, or late-filing indication in this report.

Context
An award/grant typically vests over time and does not indicate an immediate sale or purchase. Because these shares vest in the future, they may be subject to forfeiture or transfer restrictions until vesting—so this is primarily a compensation/retention action rather than an immediate market commitment.
