Quanterix Releases Financial Results for the Third Quarter of 2025
BILLERICA, Mass. – November 10, 2025 - Quanterix Corporation (NASDAQ: QTRX), a company transforming healthcare by accelerating biomarker breakthroughs from discovery to diagnostics, today announced financial results for the third quarter ended September 30, 2025.
“During the third quarter, we delivered on our revenue expectations despite challenging market conditions,” said Masoud Toloue, Chief Executive Officer of Quanterix. “Equally important, we achieved key integration milestones from our Akoya transaction — keeping us firmly on track to realize $85 million in annualized synergies and reach cash flow break-even in 2026. Together, we have built a stronger, more scalable company with the foundation to drive sustained growth, profitability, and cash flow in the years ahead.”

“Our Alzheimer’s diagnostics business also continues to accelerate. With a positive Medicare pricing recommendation and expanding partnerships across Asia, we are advancing toward a future where blood-based testing for neurodegenerative disease becomes standard clinical practice — and Quanterix is at the center of that transformation.”
Third Quarter Financial Highlights
•Revenue of $40.2 million, an increase of 12.3% compared to $35.8 million in the prior year.
•GAAP gross margin of 42.8%, as compared to 56.3% in the prior year. Adjusted gross margin (non-GAAP) of 45.9% as compared to 50.7% in the prior year.
•Adjusted EBITDA (non-GAAP) loss of $11.9 million, compared to a loss of $5.5 million in the prior year. The increase is primarily related to higher acquisition and restructuring charges.
•The Company ended the third quarter with $138.1 million of cash, cash equivalents, marketable securities, and restricted cash. Adjusted cash usage, after accounting for one-time deal and restructuring costs, was $16.1 million. Adjusted cash usage is expected to decline in Q4 2025 due to improved working capital performance and a full quarter effect of cost synergies. The company continues to expect it will end 2025 with approximately $120 million in cash, cash equivalents, marketable securities, and restricted cash.
Operational and Business Highlights
•Executed key integration activities in the quarter, capturing $67 million of cost synergies and savings. Key integration milestones include:

•Commercial: Combined the Quanterix and Akoya sales organizations, under one sales leadership, selling one combined portfolio of products.
•Operations: Consolidated four manufacturing and lab facilities into two main sites in Billerica and Burlington Massachusetts.
•Back Office/G&A: Eliminated nearly all redundant public company costs and initiated a series of IT systems integrations.

•Established new partnerships in the Asia-Pacific region, including All-Eight (Singapore); Union Clinical Laboratory (Taiwan); and NSW Health Pathology (Australia).

•Launched eight new Simoa assays through the first nine months of the year.

•Delivered multiple recent spatial and immuno-oncology presentations, including more than a dozen poster presentations, at the 40th annual Society for Immunotherapy of Cancer (SITC), demonstrating growing adoption of Quanterix’s high-plex spatial proteomics and AI-driven analysis platforms, underscoring their translational impact in uncovering immune resistance mechanisms and predictive biomarkers across multiple cancer indications. The Company also launched a new Metabolism Spike-in Module, designed for the PhenoCycler-Fusion and the PhenoCode™ Discovery IO60 Human Protein Panel.
2025 Full Year Business Outlook
The Company is reiterating its previous guidance for 2025 revenues to be in a range of $130 to $135 million, which includes approximately two quarters of performance from Akoya. On a pro forma basis, assuming the two companies were combined for the full year, the Company expects to generate 2025 revenue of between $165 and $170 million.




Quanterix expects GAAP and adjusted gross margin (non-GAAP) to be in the range of 45% to 47%.

Finally, the Company anticipates 2025 adjusted cash usage to be approximately $34 to $38 million. With the previously announced expense reductions, Quanterix expects to exit 2025 with approximately $120 million in cash, cash equivalents, marketable securities, and restricted cash and expects to achieve cash flow breakeven performance in 2026.

Use of Non-GAAP Financial Measures
To supplement our financial statements presented on a U.S. GAAP basis, we present the following non-GAAP financial measures:
•Adjusted EBITDA and adjusted EBITDA margin: We define adjusted EBITDA as net income (loss) adjusted to exclude interest income, income tax (expense) benefit, depreciation and amortization expense, stock-based compensation expense, acquisition and integration related costs, impairment and restructuring, and certain other items which include other charges or benefits resulting from transactions or events that are highly variable, significant in size, and that we do not believe are indicative of ongoing or future business operations. These items are discussed in more detail below the tables reconciling the GAAP to non-GAAP measures. Adjusted EBITDA margin is calculated as adjusted EBITDA divided by total revenues.
•Adjusted cash usage: We calculate cash usage as the total change in cash, cash equivalents, and restricted cash adjusted to include the net change from purchases, sales, and maturities of marketable securities (excluding any interest receivable). Adjusted cash usage is calculated as cash usage further adjusted to exclude cash payments related to transactions or events that are highly variable, significant in size, and that we do not believe are indicative of ongoing or future business operations.
•Adjusted gross profit, adjusted gross margin, adjusted total operating expenses, and adjusted loss from operations: We calculate these non-GAAP financial measures by including shipping and handling costs for product sales within cost of product revenue instead of within selling, general and administrative expenses. Additionally, we exclude amortization of certain acquired intangible assets, acquisition and integration related costs, and certain other items which include other charges or benefits resulting from transactions or events that are highly variable, significant in size, and that we do not believe are indicative of ongoing or future business operations. Adjusted gross margin is calculated as adjusted gross profit divided by total revenues.
We believe that presentation of these non-GAAP financial measures provides supplemental information useful to investors in understanding our underlying operating results and trends. We use these non-GAAP financial measures to evaluate our operating performance in a manner that allows for meaningful period-to-period comparison and analysis of trends in our business and our competitors. We believe that presentation of these non-GAAP financial measures provides useful information to investors in assessing our operating performance within our industry and to allow comparability with the presentation of other companies in our industry.
The non-GAAP financial measures presented here should be considered in conjunction with, and not as a substitute for, the financial information presented in accordance with U.S. GAAP. For example, adjusted EBITDA excludes a number of expense items that are included in net loss and adjusted cash usage excludes certain actual cash payments. As a result, positive adjusted EBITDA or positive adjusted cash usage may be achieved even where we record a significant net loss or reduction in our cash and marketable securities balances in accordance with U.S. GAAP.
Investors are encouraged to review the reconciliation of these non-GAAP financial measures to their most directly comparable GAAP financial measures set forth in the tables captioned “Reconciliation of GAAP to Non-GAAP Financial Measures” in the section below.
Additionally, we make certain forward-looking statements about our future financial performance that include non-GAAP financial measures, which are difficult to predict for future periods because the nature of the adjustments pertains to events that have not yet occurred. We do not forecast many of the excluded items for internal use and therefore information reconciling forward-looking non-GAAP financial measures to U.S. GAAP financial measures is not available without unreasonable effort and is not provided. The occurrence, timing, and amount of any of the items excluded from U.S. GAAP to calculate non-GAAP financial measures could significantly impact our U.S. GAAP results.
