Heartflow CFO Vikram Verghese Withholds Shares for Taxes

What Happened Vikram Verghese, Chief Financial Officer of Heartflow, acquired 671 shares under the company's employee purchase plan on March 6, 2026, at $16.15 per share (total $10,837). In early August he had a total of 2,010 shares disposed of via tax-withholding/retention: 1,537 shares on Aug 6 at $27.19 ($41,791) and 473 shares on Aug 7 at $28.82 ($13,632). These August transactions were to satisfy tax withholding or remittance obligations rather than open-market sales.

Key Details

• Transaction types: A (award/acquisition under ESPP) on 2026-03-06; F (payment of exercise price/tax withholding or retention) on 2026-08-06 and 2026-08-07.
• Dates & prices:
  • 2026-03-06: 671 shares @ $16.15 — $10,837 (ESPP acquisition).
  • 2026-08-06: 1,537 shares @ $27.19 — $41,791 (withheld/retained).
  • 2026-08-07: 473 shares @ $28.82 — $13,632 (withheld/retained).
• Total shares withheld/retained in August: 2,010 shares, total value ~$55,423.
• Footnotes:
  • F1: March acquisition was under the Issuer’s Employee Stock Purchase Plan and exempt under Rule 16b-3(c); the filing says the reported share balance reflects total holdings but does not list a numeric total.
  • F2: The August disposals represent shares retained by the issuer to satisfy income tax withholding in connection with RSU vesting/net settlement.
• Filing timeliness: The Form 4 was filed on 2026-08-10 reporting transactions back to 2026-03-06 and early August, which is outside the usual two-business-day window for Form 4 reporting (i.e., filing is late).

Context The March transaction is a routine ESPP purchase (a direct acquisition, generally considered a modest bullish signal). The August transactions are tax-withholding/retention events tied to RSU vesting or net settlement — these are administrative and do not represent open-market sales that would signal a change in conviction. For retail investors, purchases under ESPPs are more informative than routine withholding; note the filing delay when assessing timeliness of insider disclosure.
