On August 17, 2026, Executive Vice President Alaine Susan Walsh had 3,590 shares of AvalonBay Communities, Inc. common stock deemed acquired pursuant to performance-based restricted stock units in connection with the completion of AvalonBay’s merger of equals with Equity Residential, and simultaneously all 13,019 shares of AvalonBay common stock previously held were converted and reported as disposed of, reflecting the automatic exchange into Equity Residential (now Vivmark Residential) equity under the merger terms. In addition, 2,444 employee stock options with a $180.32 exercise price were reported as disposed of for Form 4 purposes as they were converted into options on Equity Residential shares using the agreed exchange ratio; these events represent equity conversion and compensation-related vesting rather than open-market purchases or sales. After these transactions, the Form 4 reports zero AvalonBay common stock and zero AvalonBay options directly held, with the economic interest effectively rolled into the surviving issuer’s securities pursuant to the merger.
