O SULLIVAN MICHAEL B 4

What Happened
Michael B. O'Sullivan, CEO of Burlington Stores, had 24,376 shares disposed on March 23, 2026 as a payment to satisfy tax withholding obligations related to the settlement of performance-based restricted stock units (RSUs). The shares were recorded at $0.00 per share and there were no cash proceeds to the insider — this was a share-withholding for taxes, not an open-market sale.

Key Details

• Transaction date: 2026-03-23; filing date (Form 4): 2026-03-25 (filed timely).
• Reported transaction type/code: F — payment of exercise price or tax liability (share withholding).
• Shares involved: 24,376 shares withheld; price reported: $0.00; proceeds: $0.
• Footnote: F1 — shares were withheld to satisfy tax withholding obligations on performance-based RSU settlement.
• Shares owned after the transaction: Not specified in this filing.

Context
Share withholding to cover taxes on vested RSUs is a routine administrative action and does not represent an open-market sale or a cash inflow to the insider. Transaction code F indicates these shares were used solely to cover tax liabilities associated with the RSU settlement. For investors, such withholdings are generally neutral on their own and do not necessarily signal the insider’s view of the company.
