Quanterix Corporation Releases Operating Results for Third Quarter 2018

85% revenue growth

Reclaimed unrestricted IVD rights

Lexington, Mass. — November 1, 2018 —Quanterix Corporation (NASDAQ:QTRX), a company digitizing biomarker analysis to advance the science of precision health, today announced financial results for the three months and nine months ended September 30, 2018.

“This third quarter has been an incredibly productive one for our company, as we continue to achieve strong momentum and hit important milestones, including gaining back unrestricted rights to our Simoa technology for the in vitro diagnostics (IVD) markets,” said Kevin Hrusovsky, Chief Executive Officer, President and Chairman. “Our Simoa technology is at the bleeding edge of the biomarker revolution, which has gained considerable traction recently as biomarkers are increasingly being recognized for their abilities to transform treatment options by accelerating development of more effective and safer drugs for all disease categories, and then longer-term, enabling and empowering individuals to take control of their lives and prevent disease.”

Third Quarter 2018 Financial Highlights

Key financial results for the third quarter are shown below:

Q3 2018 revenue includes a one-time item of $1.3M related to termination of a licensing agreement with bioMérieux for the Simoa technology. Revenue growth would have been 61% excluding this item.

YTD 2018 Financial Highlights

Key financial results for 2018 YTD are shown below:
