DONNELLY WILLIAM P 4

What Happened William P. Donnelly, Executive Chair and director of Quanterix Corp (QTRX), was granted 6,178 shares on 2026-04-01 as compensation for board service. The Form 4 lists the transaction as an award/acquisition (code A) at $0.00 reported acquisition value — the shares were issued in lieu of cash fees for Q1 2026.

Key Details

• Transaction date: 2026-04-01; Form 4 filed: 2026-04-07 (filed after the 2-business-day window for Form 4s — appears late).
• Transaction type/code: Award/Grant (A).
• Shares acquired: 6,178; Reported acquisition price/value on Form 4: $0.00.
• Shares owned after the transaction: not disclosed in the provided filing excerpt.
• Footnote: Grant consists of stock issued in lieu of cash board fees for the first quarter of 2026.

Context This was a compensation grant (stock issued instead of cash) rather than an open-market purchase or sale — such awards are routine for board service and do not by themselves indicate the insider’s market view. The $0 acquisition value on the Form 4 reflects reporting mechanics and should not be taken as market value. The filing date suggests the Form 4 was submitted later than the SEC’s typical 2-business-day deadline for insider reporting.
