"We delivered higher than expected topline growth in the third quarter, with revenues up 6.3% sequentially, despite continued market softness. This first step in restoring growth reflects sequential improvement across all our businesses. The actions we initiated last quarter to improve commercial performance, including reorganizing our teams and adding experienced leadership and discipline, should accelerate our execution in the fourth quarter and beyond," said Everett Cunningham, President & CEO of Quanterix.

He added, "We are confident about the benefits and differentiated positioning of our research tools and diagnostics businesses, especially with new commercial leadership focused on sustained growth. Our continued innovation in ultra-sensitive protein-detection in blood and high plex spatial analysis in tissue provides us with market advantages in targeted discovery and translational research. Lastly, we have now established a strong foundation for Quanterix in diagnostics, through strategic investments and partnerships, enabling us to focus on achieving key milestones in Alzheimer’s disease testing, with our single-site Alzheimer’s disease five biomarker blood test."

Third Quarter Financial Highlights

•Revenue of $35.0 million, an increase of 6.3% compared to the second quarter.
•GAAP gross margin of 38.6% down 90 basis points (bps) compared to the prior year. Adjusted gross margin (non-GAAP) of 47.4% up 150 bps vs. the prior year.
•Net loss of $21.6 million, an improvement of 35.6% compared to the prior year. Adjusted EBITDA (non-GAAP) loss of $12.2 million a decline of 2.4% vs. the prior year.
•The Company ended the third quarter with $80.7 million of cash, cash equivalents, marketable securities, and restricted cash.

Operational and Business Highlights

•Quanterix finished building its senior management team for planned growth, especially in the diagnostics business. As previously announced, Jim Gute was named Chief Commercial Officer in mid-August, and Dr. Yuri Fesko was named the company’s first Chief Medical Officer in September, bringing considerable expertise in clinical and regulatory management, which is already benefiting the Company’s commercial efforts.

•Additional milestones to advance clinical adoption of blood-based Alzheimer’s disease testing were announced, including expanded insurance coverage. Beginning November 1, 2026, traditional Medicaid members and state employees in Florida can receive coverage for qualifying blood-based biomarker tests, including Quanterix’s LucentAD Complete, when medical necessity criteria are met.

•Quanterix added two new commercial partnerships with key regional full-service clinical reference labs, Sherman Abrams Lab in New York and TruPath in Mississippi. These relationships are underway and generating opportunities for diagnostics revenue, adding to existing partnerships.

•New regulatory approvals advanced access to neurology biomarker testing in China based upon Quanterix’s HD-X and SR-X instruments and testing kits for four biomarkers. Innovita Biological Technology Co., a leading Chinese diagnostics company, is broadening access to blood biomarker testing in China, as part of our strategy to bring our SIMOA–powered diagnostics capabilities to large markets worldwide by working with strong regional commercial partners.
•Quanterix launched additional assay menu options for its SIMOA platform, as part of a commitment to expanding research tools on new biomarkers for Alzheimer’s and other neurodegenerative diseases.

•Underscoring Quanterix’s leadership in spatial biology through its Content Innovation Engine, the Company announced three new spatial products at the European Society for Spatial Biology meeting in September. The PhenoCode 2.0 Molecular Barcoding Kit is now in full commercial release, enabling researchers to barcode virtually any antibody in applications spanning immuno-oncology, neuroscience and other areas. The TIME panel, providing a broader view of the tumor immune microenvironment, and a high-plex ADC panel that enables co-measurement of ADC target expression alongside tumor immune contexture within a single tissue section, addressing demand for combination biology readouts, are both shipping in early 2027.
•Quanterix’s Accelerator Lab is now accepting requests for custom ADC panel development, widening access to the strength of its ADC combination biology fully managed service for biopharma and translational teams.
2026 Business Outlook
