Quest Diagnostics (DGX) SVP Karthik Kuppusamy Receives Award, Sells Shares

What Happened
Karthik Kuppusamy, Senior Vice President, Clinical Solutions at Quest Diagnostics, had a performance stock award settle on March 4, 2026: 6,200 shares were issued to him at $204.86 per share (value ≈ $1,270,132). On the same date he disposed of 2,628 shares at $204.86 per share (proceeds ≈ $538,372); the filing shows the disposal was to the issuer to satisfy tax withholding obligations.

Key Details

  • Transaction date: 2026-03-04; filing date: 2026-03-06 (appears timely).
  • Awarded: 6,200 shares @ $204.86 (total ≈ $1,270,132). (Code A: award/acquisition.)
  • Disposed: 2,628 shares @ $204.86 (total ≈ $538,372). (Code S: sale/disposition; per footnote, to issuer for tax withholding.)
  • Footnotes:
    • F1: Shares issued in settlement of a performance stock award under Rule 16b-3(d).
    • F2: Disposition (sale/surrender) of shares to issuer solely to cover tax withholding from the award.
    • F3: Notes that some underlying shares may reflect periodic acquisitions by the company 401(k) trustee (info from plan administrator).
  • Shares owned after the transactions: not specified in the provided filing excerpt.

Context
This was a settlement of a performance award rather than an open-market buy. The partial disposal appears to be a routine tax-withholding action tied to the award, which is common and does not necessarily indicate a change in the insider’s view of the company. For retail investors, purchases or open-market buys typically carry more informational weight than award settlements or withholding-related sales.
