Sumner R Nichole 4

What Happened

• Sumner R. Nichole, Vice President & Controller of Olin Corporation (OLN), received equity awards on February 18, 2026. The filing shows acquisition of 79 shares of common stock (RSP) and 6,403 restricted stock units (RSUs), all reported at $0 per share (award). Total units granted/received = 6,482.
• The 6,403 units are derivative awards (RSUs) — contingent rights to receive one share each upon vesting. No cash was paid; this is an award/grant rather than an open‑market purchase or sale.

Key Details

• Transaction date: 2026-02-18; Form 4 filed: 2026-02-20 (reporting period 2026-02-18) — filing appears timely.
• Awards: 79 shares (RSP) at $0.00; 6,403 RSUs (derivative) at $0.00.
• Shares/units after transaction: at least 6,482 total units reported (79 shares held under the RSP + 6,403 unvested RSUs).
• Footnotes: F1 — 79 shares are held under the Olin Retirement Savings Plan (RSP) as reported by the plan administrator. F2 — each RSU equals a contingent right to one share. F3 — the RSUs vest in three annual installments beginning Feb 18, 2027.
• Transaction code: A = Award/Grant. No sale or purchase reported; no indication of a 10b5-1 plan or tax‑withholding sale in this filing.

Context

• RSUs are derivative awards that convert to actual shares only when they vest; until then they are not freely tradable. Vesting begins Feb 18, 2027 and occurs in three annual installments per the filing.
• Awards to employees are common and reflect compensation, not an immediate market buy/sell signal. This filing documents compensation-related equity grants rather than an insider buying shares in the open market.
