Exhibit 99.1
Quanterix Releases Financial Results for the Second Quarter of 2026
Reports $32.9 million in revenue and $96.9 million of cash and marketable securities
Company accelerating initiatives to drive commercial effectiveness
Revises financial outlook for 2026 and extends date for attaining cash-flow break-even
BILLERICA, Mass. – August 10, 2026 -- Quanterix Corporation (NASDAQ: QTRX), a global leader in precision biomarker science, today announced financial results for the second quarter ended June 30, 2026.
“We made meaningful progress in the second quarter, including strengthening our leadership team and preserving cash better than planned. However, revenue fell short of our expectations, driven by execution challenges and continued market softness. We are taking immediate and significant action to improve commercial performance, including reorganizing our teams and adding seasoned leadership to sharpen accountability, accelerate execution, and improve operating results in the second half and beyond,” said Everett Cunningham, President & CEO of Quanterix. “We remain confident in the strength and differentiated positioning of both our research tools and diagnostics businesses, especially with enhanced commercial leadership and discipline enabling a renewed focus on returning to sustained growth. Our capabilities in ultra-sensitive protein-detection in blood and high plex spatial analysis in tissue, combined with a differentiated multi-analyte approach, position us well across targeted translational research and diagnostics. With strategic Diagnostics investments underway, our management team can now focus on achieving key milestones in Alzheimer’s disease testing, including completing three clinical utility studies and advancing our FDA roadmap.”
Second Quarter Financial Highlights
•Revenue of $32.9 million, an increase of 34% compared to $24.5 million in the prior year.
•GAAP gross margin of 38.5%, as compared to 40.9% in the prior year. Adjusted gross margin (non-GAAP) of 47.9% compared to 41.8% in the prior year. Prior year GAAP margins are updated to reflect a change in accounting policy in Q1’26 related to shipping and handling costs. Shipping and handling costs for product sales are now recorded in the cost of product revenue in the Company’s GAAP financials.
•Adjusted EBITDA (non-GAAP) loss of $10.0 million, compared to $13.7 million in the prior year.
•The Company ended the second quarter with $96.9 million of cash, cash equivalents, marketable securities, and restricted cash. Adjusted cash usage, after accounting for integration and certain employee separation costs of $1.7 million, was $4.0 million in the second quarter, a decrease in usage of $10.8 million from the first quarter of 2026.
•The Company completed its ERP system integration, the final step of the Akoya acquisition integration program that realized $85 million in savings on an annualized basis.
•Quanterix incurred a $26.9 million goodwill impairment related to the Akoya acquisition as required under GAAP accounting based on recent circumstances within the business. The adjustment does not impact operations or liquidity.
Operational and Business Highlights
•Quanterix finished building its senior management team ahead of its anticipated higher growth phase, especially in the Diagnostics business. Jim Gute was named Chief Commercial Officer, as announced separately today. Industry veteran Geoff Albrecht was appointed Senior Vice President and General Manager of Diagnostics, Anthony Catalano was named Chief Operating Officer and Jason Faessler was appointed Chief Financial Officer.
•Several milestones to advance clinical adoption of blood-based Alzheimer’s testing were announced, including commercial insurance coverage. Beginning July 1, 2026, members covered under Anthem Blue Cross and Blue Shield medical policies can receive coverage for qualifying blood-based biomarker testing, including Quanterix’s Lucent AD® Complete, when medical necessity criteria are met.
•A peer-reviewed study evaluating Lucent AD® Complete alongside an algorithmic immunoprecipitation mass spectrometry (IP-MS) approach on a shared patient cohort demonstrated the high diagnostic parity and three-fold reduced diagnostic ambiguity provided by Quanterix’s multi-analyte algorithmic blood testing approach.


•New clinical data presented at the Alzheimer’s Association International Conference (AAIC) 2026 highlighted how multi-biomarker testing improves detection of early Alzheimer's and provides a more comprehensive framework for guiding patient care.
•Quanterix was selected as a Co-Investigator institution in the PD-BUILD program, in the Aligning Science Across Parkinson’s Collaborative Research Network 2026 expansion, supported by The Michael J. Fox Foundation. This multi-year grant funds development and deployment of high-quality biomarker tools aimed at enabling earlier detection, improved patient stratification, and more effective monitoring of Parkinson’s disease in clinical research. Quanterix and its Simoa platform will develop and distribute validated single-plex and multiplex biomarker assays to Parkinson’s disease researchers globally.
•Quanterix launched Simoa® Ultra-Sensitive Immunoassay NPTX2, an important emerging synaptic biomarker.
•Two new spatial products were launched: Spatial Molecular Barcoding kit for the Phenocycler Fusion for early access and Spatial Spectral DAPI 2.0 for the Phenoimager HT.
2026 Business Outlook
Quanterix currently expects revenues of $142-148 million, which assumes no underlying improvement in the academic or pharmaceutical end markets, compared to its earlier expectation for annual revenues of $169-174 million. In addition, we expect non-GAAP gross margins in a range of 48-50%, compared to non-GAAP gross margins of 49-53% previously. Quanterix now anticipates achieving cash flow breakeven in 2027 but is currently forecasting approximately $80 million for the 2026 year-end cash balance, compared to $100 million previously. The company expects to end the year with no debt.

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, impairments, and certain other items which include other charges or benefits resulting from transactions or events that are unusual or infrequent, 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 unusual or infrequent, 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 excluding amortization of certain acquired intangible assets, acquisition and integration related costs, impairments, and certain other items which include other charges or benefits resulting from transactions or events that are unusual or infrequent, 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.
During the first quarter of 2026, we changed our accounting policy for classifying shipping and handling costs for product sales and they are now recorded in cost of product revenue. Historically, these shipping and handling costs were recorded in selling, general and administrative expenses, and we calculated our non-GAAP financial measures by including these shipping and handling costs within cost of product revenue. We applied this change in accounting policy retrospectively to all periods presented, and no longer reclassify shipping and handling costs in our non-GAAP financial measures.
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 allows 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 “Reconciliations 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.
