William P. DonnellyTSR underperformance trigger: QTRX 3-year return -73.0% vs IHI (iShares US Medical Devices ETF) -6.5%, gap of -66.5pp exceeds 30pp threshold for negative absolute TSR; director joined August 2023 (>24 months tenure, trigger applies)

Mr. Donnelly has served on the board since August 2023, which is more than 24 months ago, so the TSR trigger applies: Quanterix's stock has fallen 73% over the past three years while the Medical Device ETF Benchmark (IHI — iShares US Medical Devices ETF) declined only 6.5%, a gap of 66.5 percentage points that far exceeds the 30-point threshold required to trigger an AGAINST vote for a company with negative absolute returns; the 5-year return data shows an even worse -95% over five years confirming this is not a transient shortfall.

For Analysis

✓ FOR
Ivana Magovčević-Liebisch, Ph.D., J.D.

Dr. Magovčević-Liebisch joined the board in October 2024, which is fewer than 24 months ago, so she is exempt from the TSR underperformance trigger under the policy's new-director exemption; she brings over 25 years of biotech and pharma executive experience and no other disqualifying factors were identified.

Of the two director nominees, we vote FOR Ivana Magovčević-Liebisch (exempt from TSR trigger as a director with less than 24 months of tenure) and AGAINST William P. Donnelly (board member since August 2023, whose tenure fully overlaps with severe stock underperformance of 66.5 percentage points versus the IHI — iShares US Medical Devices ETF benchmark, well above the 30-point trigger threshold for companies with negative absolute returns).

Pay-for-performance misalignment: variable/incentive pay above benchmark while stock declined 73% over 3 years vs IHI (iShares US Medical Devices ETF) at -6.5%, a gap of -66.5ppMid-year downward revision of bonus targets without reducing payout percentage — corporate performance factor set at 95% despite targets being lowered significantlyLong-term equity awards are time-based RSUs and stock options with no performance conditions, functioning as effectively fixed pay in practice

The company's stock has lost 73% of its value over three years while the Medical Device ETF Benchmark (IHI — iShares US Medical Devices ETF) declined only 6.5%, yet the former CEO received total compensation of $5.25 million including nearly $3.9 million in equity awards and a cash bonus of $641,250, and incentive targets were revised downward mid-year in August 2025 and then the committee further reduced the mathematically calculated payout from 105% to 95% using discretion — a soft signal of awareness of the disconnect, but the awards were still paid at near-target levels. The long-term equity program uses only time-based vesting with no performance conditions tied to stock price or financial outcomes, meaning these awards vest regardless of whether shareholders benefit, which the policy treats as incentive pay disguised as variable compensation. Given the severe underperformance versus the IHI benchmark and above-benchmark incentive pay that is not conditioned on performance outcomes that align with shareholder experience, a vote AGAINST is warranted.

Auditor Ratification

Audit Fees

$2,027,866

Non-Audit Fees

$386,975

Non-audit fee ratio exceeds 50%: non-audit fees (tax $105,000 + other $281,975 = $386,975) represent approximately 19.1% of audit fees on a standalone basis — WAIT: recalculating: $386,975 / $2,027,866 = 19.1% which is below 50%; however Other fees of $281,975 relate to services provided before KPMG was appointed as auditor and may warrant scrutiny

The non-audit fees paid to KPMG total $386,975 (tax fees of $105,000 plus other fees of $281,975), which represents approximately 19% of the audit fees of $2,027,866 — well below the 50% threshold that would trigger an AGAINST vote; KPMG's tenure is not disclosed in the proxy so the tenure trigger cannot be confirmed and per policy we default to FOR on undisclosed tenure; no material restatements attributable to audit failure were identified, and KPMG is a Big 4 firm appropriate for a company of this size.

Overall Assessment

This ballot presents four proposals at Quanterix's 2026 annual meeting; the most significant governance concerns are severe stock underperformance (-73% over three years versus the IHI — iShares US Medical Devices ETF benchmark at -6.5%) and a compensation program that pays near-target bonuses and grants time-based-only equity while shareholders have lost most of their investment. We vote AGAINST Board Chair William P. Donnelly due to his tenure overlap with the underperformance period, AGAINST the Say on Pay proposal due to pay-for-performance misalignment, and FOR the auditor ratification (KPMG, non-audit fee ratio well below the 50% threshold) and the newly joined director Ivana Magovčević-Liebisch (exempt from the TSR trigger as a director with fewer than 24 months of service).
