Castle Angela M 4

What Happened
Angela M. Castle, Vice President and Chief Legal Officer of Olin Corporation (OLN), received equity awards on February 18, 2026. The Form 4 reports acquisition of 26 shares of common stock (through the Olin Retirement Savings Plan) and 16,007 restricted stock units (RSUs). Both items are reported at $0.00 (typical for grants/RSUs), so no cash was exchanged in the filing.

Key Details

• Transaction date: February 18, 2026; Form 4 filed February 20, 2026 (within the usual 2-business-day reporting window).
• Shares/units granted: 26 shares (RSP) + 16,007 RSUs (derivative award) = 16,033 total. Reported price: $0.00.
• RSU detail: Each restricted stock unit represents a contingent right to one share (footnote).
• Vesting: The 16,007 RSUs vest in three annual installments beginning February 18, 2027.
• RSP note: The 26 shares are held under the Olin Corporation Retirement Savings Plan and were reported by the RSP Plan Administrator (exempt under Rule 16b-3).
• Filing timeliness: Filed two days after the transaction date; not indicated as late in the filing.

Context
These entries are awards, not open-market purchases or sales. RSUs are contingent grants that convert to actual shares only as they vest; they do not represent an immediate cash investment or sale by the insider. Awards like this are common executive compensation and should be interpreted as compensation-related transactions rather than direct bullish or bearish trading signals.
