Quanterix Corporation Releases Operating Results for Fourth Quarter and Fiscal Year 2017

Lexington, Mass. — March 14, 2018 —Quanterix Corporation (NASDAQ:QTRX), a company digitizing biomarker analysis to advance the science of precision health, reported financial results for the fourth quarter and full year of 2017. Revenues for full year 2017 of $22.9M were at the high end of the range of $22.5-$22.9M, which was previously announced in January 2018.

“2017 was an important year for Quanterix, and I am pleased to report progress on a number of pivotal focus areas,”said Chief Executive Officer, President and Chairman, Kevin Hrusovsky. “In our first quarter as a public company, we continued to grow revenues, scale the company for future success and make inroads launching digital biomarker technologies into neurology, oncology and infectious disease application areas.”

Fourth Quarter Financial Highlights

Key financial results for the fourth quarter are shown below:

·                  Q4 revenue of $6.6M versus prior year Q4 of $6.7M, a decrease of 1%. Q4 2016 includes $1.8M in non-recurring revenue recognized in connection with a license; excluding that the revenue growth was 35%.

·                  Q4 product revenue totaled $4.1M versus prior year of $3.2M; Consumables drove this performance.  Product revenue included the sale of five of the newly launched SR-X benchtop reader. This launch was more than a quarter ahead of schedule.

·                  Q4 Service and Other Revenue totaled $2.3M versus prior year of $1.7M, an increase of 34%.

·                  Strong liquidity position at year-end with $79.7M of cash and $9.4M of debt.

·                  Successfully closed its initial public offering of 4,916,480 shares of common stock at a public offering price of $15.00 per share, and received $73.7M in gross proceeds from the offering, prior to deducting underwriting discounts and commissions, and offering expenses payable by the company. The shares began trading on The NASDAQ Global Market on December 7, 2017 under the ticker symbol “QTRX.”

·                  Expanded market opportunity through the launch of the new SR-X Ultra-Sensitive Biomarker Detection System™, opening the door for researchers to access ultra-sensitive protein and nucleic acid detection capabilities in a more compact and affordable system. The SR-X was made commercially available in December 2017 and Quanterix received 16 orders for the new system in Q4, with limited marketing support behind the new launch.

2017 and Recent Business Highlights

·                  Full year 2017 revenue of $22.9M, the high end of the previously provided guidance of $22.5-22.9M, versus full year 2016 revenue of $17.6M, an increase of 30% year-over-year; excluding the 2016 non-recurring revenue recognized in connection with a license, revenue growth was 45%.
