These approvals establish a broader SIMOA-powered neurology biomarker portfolio in China and represent an important step toward expanding access to blood-based biomarker testing into clinical practice within the country.

Current report

Total revenues decreased $5.3 million, or 13%, to $35.0 million for the three months ended September 30, 2026, compared to $40.2 million for the three months ended September 30, 2025.

Current report

Product revenue decreased $1.0 million, or 4%, to$25.2 million for thethree months ended September 30, 2026, compared to$26.2 million for thethree months ended September 30, 2025.

Current report

Instrument revenues were$4.4 million, a decrease of $2.8 million or 39% from $7.2 million, primarily due to weaker instrument demand from customers in both our academic and pharmaceutical end markets. We expect softness in instrument sales to continue into 2027 as a result of what we believe is a constrained capital funding environment.

Current report

Consumables and other product revenues were $20.8 million, an increase of $1.8 million or 10% from $19.0 million, primarily due to demand from pharmaceutical customers. We believe research grant funding has not returned to previous levels, which may affect the pace of recovery in our consumables revenues.

Current report

Total cost of goods sold and services decreased $2.9 million, or 12%, to$21.5 million for thethree months ended September 30, 2026, compared to$24.3 million for thethree months ended September 30, 2025.

This decrease was primarilydue to reductions in headcount and related compensation and benefit costs from the 2025 restructurings and an overall decrease in product revenue.

Current report

Research and development expense decreased $0.6 million, or 8%, to $7.4 million for the three months ended September 30, 2026, compared to $8.0 million for the three months ended September 30, 2025. The decrease was primarily due to lower headcount and related compensation and benefit costs from the 2025 restructurings and was partially offset by an increase in outside services related to planned HD-X instrument upgrades.

Current report

Selling, general and administrative expense decreased $9.6 million, or 25%, to $28.5 million for the three months ended September 30, 2026, compared to $38.0 million for the three months ended September 30, 2025. The decrease was primarily due to non-recurring due diligence and other acquisition costs related to the acquisition of Akoya in 2025 and a reduction in facilities expenses.

Current report

Product revenue increased $10.4 million, or 16%, to$74.1 million for thenine months ended September 30, 2026, compared to$63.7 million for thenine months ended September 30, 2025.

Current report

Instrument revenues were $12.2 million, an increase of $0.4 million or 3% from $11.8 million, primarily due to the acquisition of Akoya in the third quarter of 2025, which added $4.7 million during the first half of 2026. This increase was partially offset by a decrease in product revenues primarily due to weaker instrument demand from customers in both our academic and pharmaceutical end markets.

Current report

Consumables and other product revenues were $62.0 million, an increase of $10.0 million or 19% from $51.9 million, primarily due to the acquisition of Akoya the third quarter of 2025, which added $13.3 million during the first half of 2026 and and was partially offset by reduced demand from academic customers.

Current report

Cost of product revenue increased $6.6 million, or 17%, to$45.2 million for thenine months ended September 30, 2026, compared to$38.6 million for thenine months ended September 30, 2025. This increase was primarily due to the acquisition of Akoya in the third quarter of 2025, which added $10.3 million to cost of product revenue in the first half of 2026 and an increase in amortization expense related to acquired intangible assets. These increases were partially offset by lower headcount and related compensation and benefit costs from the 2025 restructurings and an overall decline in product revenue.

Current report

Research and development expense decreased $4.6 million, or 17%, to $22.5 million for the nine months ended September 30, 2026, compared to $27.1 million for the nine months ended September 30, 2025. The decrease was primarily due to a non-recurring contingent payment arrangement in 2025 associated with the acquisition of Emission and a decrease in headcount and related compensation and benefit costs from the 2025 restructurings. These decreases were partially offset by an increase in outside services related to planned HD-X instrument upgrades and the acquisition of Akoya.

Product revenue increased $6.6 million, or 39%, to$23.5 million for thethree months ended June 30, 2026, compared to$16.8 million for thethree months ended June 30, 2025. The increase was due to the acquisition of Akoya, which added $9.3 million of product revenue. For the legacy Quanterix business, product revenue decreased $2.7 million primarily due to weaker demand from both academic and pharmaceutical customers as research grant funding remains constrained and research and development spending declined.

Previous report

We expect softness in instrument sales to continue during the remainder of 2026 as a result of what we believe is a constrained capital funding environment. As we implement the strategic changes to update our HD-X and improve our commercial execution, or as funding conditions improve, we anticipate a recovery in instrument demand. We also expect the continued uncertain macro-economic environment to cause fluctuations in consumables sales during the remainder of 2026.

Previous report

Cost of product revenue increased $4.0 million, or 38%, to$14.6 million for thethree months ended June 30, 2026, compared to$10.6 million for thethree months ended June 30, 2025. This increase wasdue to the acquisition of Akoya, which added $5.1 million to cost of product revenue, including $2.9 million of amortization of acquired intangible assets. This increase was partially offset by a $1.1 million decrease in the legacy Quanterix business primarily related to reductions in headcount and related compensation and benefit costs from the May 2025 restructuring plan.

Previous report

Research and development expense decreased $1.3 million, or 14%, to $7.8 million for the three months ended June 30, 2026, compared to $9.1 million for the three months ended June 30, 2025.

Previous report

Although we previously set a cash flow breakeven target of year-end 2026, we now anticipate being cash flow breakeven in 2027. The primary factors leading to this change include increasing our investment in commercial leadership and resources across our research tools and Accelerator Laboratory businesses and building our diagnostics team and infrastructure as we focus on Alzheimer's diagnostics. Along with the changes discussed in the section titled "Recent Business Developments - Business Strategy Update", we believe that improving our commercial execution will allow us to grow without substantial macro-environment recovery. Additionally, weaker-than-expected revenue in the first half of 2026 contributed to our updated timeline. Our ability to achieve our cash flow breakeven target is dependent on our success in implementing our strategy changes and meeting revenue and expense objectives. Further, our progress could be adversely affected by economic, market, and other external factors.
