O SULLIVAN MICHAEL B 4

What Happened

• Michael B. O'Sullivan, CEO of Burlington Stores, was granted 12,292 restricted stock units (RSUs) on May 1, 2026 (acquired at $0.00). To satisfy tax withholding when RSUs vested, a total of 6,423 shares were withheld/disposed across transactions on May 1 and May 4, 2026, with a combined withholding value of about $2,031,121.

Key Details

Context

• This filing reflects an equity award (RSUs) and routine shares withheld to cover tax obligations. Withholding (code F) is common and does not necessarily signal an active decision to sell shares on the market.
• For retail investors: awards increase insider exposure over time as RSUs vest, while withheld shares reduce the net new shares delivered to the insider.
