COLLINS GARY S 4

What Happened

• Gary S. Collins, Vice Chairman and Director of Old Second Bancorp, was allocated 253 shares on 2026-03-31. The filing shows these shares at $0.00, indicating they were allocated under the Old Second Bancorp, Inc. Salary and Savings Plan rather than bought in the open market. This is an acquisition (not a sale) and appears to be a routine plan allocation.

Key Details

• Transaction date and price: 2026-03-31; 253 shares at $0.00 (transaction code J — other acquisition).
• Filing date: 2026-04-02 (appears to be filed in a timely manner).
• Shares owned after transaction: the filing excerpt does not state a single total; it notes holdings include 41,000 shares in a ROTH IRA and 37,256.085 shares in a traditional IRA, and the 253 allocated shares were reported by the Plan Trustee.
• Footnotes: F1 — 253 shares allocated during Q1 under the Salary & Savings Plan (info from Plan Trustee); F2 — some shares held in the reporting person's name in a brokerage account; F3 — referenced IRA holdings included in reported totals.
• Transaction type explained: coded as "J" (other acquisition) and reflects plan allocation, not an open-market purchase.

Context

• Allocations under salary/savings plans are common compensation or deferral events and are routine; they do not necessarily indicate the insider is expressing bullish or bearish views.
• Because the shares were recorded at $0.00, no cash changed hands in a standard purchase — this is an internal plan allocation.
