LAI GOLDMAN MYLA 4

What Happened
Myla Lai Goldman, a director of Quanterix Corp (QTRX), had 8,073 restricted stock units (RSUs) convert into 8,073 common shares on July 8, 2026. The Form 4 shows an acquisition (conversion) of 8,073 shares and a corresponding disposition of 8,073 shares at $0.00, indicating the converted shares were surrendered/withheld rather than sold for cash. No cash proceeds were reported.

Key Details

• Transaction date: July 8, 2026 (reported on Form 4 filed July 9, 2026). Transaction code: M (exercise/conversion of derivative).
• Acquired: 8,073 shares via RSU conversion (price N/A per footnote F1).
• Disposed: 8,073 shares at $0.00 (reported as a derivative disposition).
• Shares owned after transaction: not specified in the filing.
• Footnotes: F1 — RSUs convert one-for-one into common stock. F2 — These shares are from a 24,464-RSU grant dated July 8, 2025 that vests 33%/33%/34% on each anniversary; 33% = 8,073 shares.
• Filing timeliness: filed next day (timely under Form 4 rules).

Context
This was a routine equity-compensation vesting event (RSU conversion). The reported $0.00 disposition typically reflects shares withheld or surrendered to satisfy tax withholding obligations, not an open-market sale — therefore no proceeds or change in cash position are indicated. Such vesting reflects compensation being realized, not necessarily a buy or sell signal.
