Breslin Sean J. 4/A

What Happened

• Sean J. Breslin, Chief Operating Officer of AvalonBay Communities (AVB), had 7,700 shares withheld by the company to satisfy tax-withholding obligations tied to the vesting of restricted stock/performance share units. The shares were valued at $177.23 each, totaling $1,364,671. The Form 4 was amended to correct the number of shares withheld.

Key Details

• Transaction date: 2026-03-01
• Price per share: $177.23; Total value of shares withheld: $1,364,671
• Transaction code: F (shares withheld to cover tax withholding on vested awards)
• Filing: Amended Form 4 (accession 0001193125-26-277552) — amended to reflect the correct number of shares withheld
• Shares owned after transaction: The filing does not list a specific post-transaction share count in the summary provided; footnote states the reported ownership reflects direct ownership of all common shares, including restricted shares
• No indication in this summary that the transaction was part of a 10b5-1 plan or that the filing was late (this report amends a prior Form 4)

Context

• This was a routine tax-withholding disposition tied to award vesting (not an open-market sale). Withholdings to cover taxes are common and generally reflect compensation settlement, not a discretionary sell signal. The amendment corrects the originally reported withholding amount.
