Sriram Vandana 4

What Happened
Sriram Vandana, Chief Financial Officer of Quanterix Corporation (QTRX), had 4,395 shares withheld on 2026-02-04 to satisfy tax obligations related to the vesting of restricted stock units (RSUs). The Form 4 reports the withheld shares at $0.00 (no cash proceeds) — this is a tax-withholding disposition, not an open-market sale.

Key Details

• Transaction date: 2026-02-04; Form filed: 2026-02-06 (filed within the typical 2-business-day window).
• Transaction code: F (payment of exercise price or tax liability via withholding).
• Withheld shares: 4,395 at $0.00; reported as "Disposed" solely to cover taxes.
• RSUs vested: 12,678 RSUs vested and shares were withheld to cover tax obligations (footnote F1).
• Holdings note: Form footnote indicates "Includes 55,884 RSUs" (footnote F2); the filing does not report separate total post-transaction common-share count beyond the RSU disclosure.
• No cash proceeds and no open-market sale — this is routine tax withholding.

Context
Withholding shares to meet tax liabilities on RSU vesting is a common administrative action and should not be interpreted as a deliberate sale signaling management sentiment. For retail investors, purchases or open-market sales by insiders typically carry more informational weight than tax-withholding dispositions.
