Quanterix Corporation Appoints Anthony Catalano as Chief Operating Officer

What Happened Quanterix Corporation (QTRX) announced in an 8-K that it appointed Anthony Catalano as Chief Operating Officer effective May 14, 2026. The company entered into an employment agreement with Mr. Catalano providing a $400,000 initial annual base salary, a $50,000 cash sign-on bonus, and eligibility for an annual performance bonus with a target up to 50% of base salary. Michael Miller, the former COO, has transitioned to Chief Technology and Products Officer.

Key Details

• Appointment date: May 14, 2026; Employment Agreement dated April 30, 2026.
• Cash compensation: $400,000 base salary and $50,000 sign-on bonus; annual bonus target up to 50% of base.
• Equity award: RSUs equal to 0.30% of shares outstanding on his start date, vesting in four equal annual installments.
• Severance: If terminated without Cause or resigns for Good Reason — six months base salary, pro‑rated target bonus for the year, and subsidized health benefits; in a Change‑in‑Control scenario severance extends to nine months and time‑based equity fully vests. Receipt of benefits is conditioned on signing a separation agreement with customary restrictive covenants and release.

Why It Matters This is a material executive change affecting Quanterix’s operational leadership. The compensation package combines cash and equity (0.30% dilution at grant), which has implications for both near‑term cash outlays (salary, sign‑on) and long‑term share-based dilution. The severance and change‑in‑control provisions spell out potential additional cash and equity acceleration obligations. Investors should note the leadership continuity with Michael Miller remaining in a senior product/technology role and Catalano’s prior operations experience, including roles tied to the company’s Akoya acquisition.
