Enphase (ENPH) VP Mary Erginsoy Sells Shares for Tax Withholding

What Happened

  • Mary Erginsoy, Vice President and Chief Accounting Officer of Enphase Energy (ENPH), had 8,642 shares withheld by the company on March 1, 2026 to satisfy tax withholding obligations tied to vested restricted stock units (RSUs) and performance stock units (PSUs). Each share was valued at $42.27, producing total consideration of about $365,297.
  • The withholding transactions break down as: 464 shares ($19,613), 989 shares ($41,805), 1,791 shares ($75,706), and 5,398 shares ($228,173). These represent share-withholdings (dispositions) rather than open-market sells.

Key Details

  • Transaction date: 2026-03-01; Form 4 filed: 2026-03-03 (filed timely).
  • Price per share: $42.27 for all withheld lots.
  • Total shares withheld/disposed: 8,642; total value ≈ $365,297.
  • Footnotes for withholding: tied to RSU grants on Mar 8, 2023 (464 sh), Jan 15, 2024 (989 sh), Jan 14, 2025 (1,791 sh), and PSUs granted Jan 14, 2025 (5,398 sh). (Footnote F5 notes some shares are held in the Erginsoy Family Trust where she is a trustee.)
  • Form 4 indicates these are tax-withholding dispositions (code F); shares-owned-after-transaction not specified in the provided filing.

Context

  • This was a tax-withholding/net-share settlement (issuer withheld shares to cover taxes on vesting), not an open-market sale — a routine administrative action that doesn’t necessarily reflect the insider’s view of the stock.
  • For retail investors: purchases or open-market buys tend to be more informative; withholding at vesting is common and often neutral in signaling company prospects.
