Quanterix Corporation (ISIN US74766Q1013) was trading at USD 3.46 on Nasdaq on October 6, 2026 at 3:13 p.m. ET, down 9.06 percent from the prior close of USD 3.81. The move leaves the stock 60.49 percent below its 52-week high of USD 8.77, making the company guidance reset the key issue for investors.

Revenue grows but misses estimates

In the second quarter of 2026, Quanterix generated USD 32.9 million in revenue, up 34 percent from USD 24.5 million in the same quarter of 2025. According to StockTitan, the result was below the USD 37.48 million consensus, while adjusted gross margin reached 47.9 percent and GAAP gross margin was 38.5 percent.

The earnings shortfall was paired with a sharp change in the full-year outlook. StockTitan reports that Quanterix lowered 2026 revenue guidance to USD 142 million-148 million from USD 169 million-174 million and moved expected cash-flow breakeven to 2027.

Spatial biology adds a second track

Quanterix is also building a product-based counterweight to the near-term revenue pressure. In a September 25, 2026 release, Quanterix said one spatial biology program had shipped and two additional programs were confirmed for delivery in the fourth quarter of 2026.

The release names the PhenoCode 2.0 Molecular Barcoding Kit as globally available and identifies the TIME and high-plex ADC panels as fourth-quarter shipments. That pipeline matters because Quanterix combines its Simoa biomarker technology with spatial biology tools added through its Akoya Biosciences business.

Analyst target stays at USD 3

The same overview records Canaccord Genuity lowering its target from USD 4.00 to USD 3.00 on August 17, 2026, and TD Cowen making the same cut on August 11, 2026. Against the October 6 price of USD 3.46, the consensus target lies 13.29 percent below the stock.
