Aarnes Robert B 4

What Happened

• Robert B. Aarnes, an outside director of MSC Industrial Direct Co., Inc. (MSM), received a grant of 1,603 restricted stock units (RSUs) on January 23, 2026. The award is reported as a derivative acquisition (code A) at $0.00 because it is an equity award rather than a cash purchase.
• Each RSU represents a contingent right to receive one share of common stock upon vesting. No immediate shares or cash changed hands at grant.

Key Details

• Transaction date: 2026-01-23; Filing date: 2026-01-26 (filed promptly following the grant).
• Grant: 1,603 RSUs; Reported price/acquisition amount: $0.00 (award).
• Vesting: RSUs vest on 2027-01-23 provided Aarnes continues to serve as an outside director; vested shares will be delivered upon vesting (footnotes F1–F2).
• Post-transaction share ownership: not specified in the Form 4 filing.
• Transaction type: Award/Grant (derivative equity award). No 10b5-1 plan, tax-withholding, or sale noted in the filing.

Context

• RSU grants to outside directors are a common form of compensation and do not represent an immediate market purchase or sale; they become share ownership only if and when they vest and are delivered.
• Because this is an award rather than a purchase or sale, it should be viewed as compensation disclosure rather than a direct insider investment signal.
