Summy Amy B. 4

What Happened

• Amy B. Summy, EVP and Chief Marketing Officer of Labcorp (LH), had Restricted Stock Units (RSUs) convert into 445 shares (223 on Feb 6, 2026 and 222 on Feb 7, 2026).
• To satisfy tax withholding, 92 shares were withheld on Feb 6 at $277.20 for $25,502, and 80 shares were withheld on Feb 9 at $274.01 for $21,921 — total tax withholding ≈ $47,423. The RSU/derivative units were cancelled on conversion (reported as derivative disposals at $0.00).

Key Details

• Transaction dates: Feb 6–7, 2026 (conversion); tax withholding reported Feb 6 and Feb 9, 2026. Filing date: Feb 10, 2026; Period of Report: Feb 6, 2026.
• Prices/values: tax-withheld shares valued at $277.20 and $274.01 for totals of $25,502 and $21,921 respectively.
• Shares owned after transaction: not specified in the filing (the form lists RSU activity and withholding but does not state total post-transaction holdings).
• Footnotes: F1 = each RSU = 1 share; F2 = shares withheld to satisfy tax withholding; F3/F5 = vesting schedules for the grants involved; F4 = notes aggregate RSU count (number itself not shown in this summary).
• Exhibit: Exhibit 24 — Power of Attorney. No indication this filing was late.

Context

• This was a routine RSU vesting/conversion event, not an open-market buy or sale driven by trading intent. The withheld shares reflect tax withholding (a common cashless settlement), not an active sale to realize gains. Purchases typically signal stronger insider confidence; conversion and withholding are standard compensation mechanics.
