Quanterix to present at J.P. Morgan Healthcare Conference on January 13, 2021 at 3:40 pm ET

Billerica, Mass. – January 13, 2020 — Quanterix Corporation (NASDAQ: QTRX), a company digitizing biomarker analysis to advance the science of precision health, today provided operational and preliminary financial highlights for the fourth quarter and fiscal year ended December 31, 2020.

“While last year brought extraordinary challenges for the world, it also amplified the critical potential of our precision health strategy to address acute issues associated with the spread of COVID-19 virus and longer-term health concerns resulting from the infection,” said Kevin Hrusovsky, Chairman, Chief Executive Officer and President, Quanterix and Founder of Powering Precision Health (PPH). “Our timely pivot to address the pandemic enabled us to keep our employees safe and by year-end, deliver a robust suite of novel COVID-19 testing solutions to support the battle in 2021. Our advances in ultra-sensitive proteomics testing enable top researchers to tackle important COVID challenges and accelerate our Neurology tools strategy with vital new additions to our assay menu supporting both Alzheimer’s and COVID-19 research and diagnostics. We enter 2021 with short and long-term growth catalysts fueling our potential to scale our powering precision health strategy.”

Operational Highlights:

• Awarded an $18.2M contract with the NIH through its RADx initiative to accelerate the continued development and scale-up of a novel SARS-CoV-2 antigen test.
• Received FDA Emergency Use Authorizations for novel SARS-COV-2 antigen test (after year-end) and for semi-quantitative antibody test, underscoring our longstanding science-first mentality and deep dedication to the highest standards of quality and scientific rigor across our business.
• Leveraging the unparalleled ultra-sensitivity of Simoa, enabled several leading researchers globally, including at the NIH, to begin tackling leading-edge COVID challenges, such as establishing potential for blood based anti-viral endpoints for new drug therapies and understanding the long-term complications of COVID-19.
• Expanded our differentiated Neurology menu to include tau phosphorylated at threonine 181 (pTau-181), a highly specific biomarker for the study of Alzheimer’s disease pathology, in cerebral spinal fluid (CSF), serum and plasma as well as launched Neuro Multiplex assays associated with many neurodegenerative diseases yielding high growth potential. Our biomarker portfolio is now supporting leading Alzheimer’s programs globally.
• Novartis’ multiple sclerosis (MS) drug KESIMPTA® (ofatumumab), which utilized Nf-L as secondary endpoint, was approved by the FDA.
• Quanterix’ Simoa technology was highlighted in a record 443 new publications in 2020, bringing total Simoa-specific inclusions to over 1,120.  Also, was invited to present at several marquis symposiums showcasing our Precision Health vision and potential to catalyze asymptomatic medicine.
• Instrument installed base increased by 34% to 535, despite access challenges posed by COVID-19. This includes 93 HD-X placements with over 50% new installations and 84 new SR-X and SP-X placements.
• Solidified Simoa’s technological leadership by achieving a 100x sensitivity improvement in a pilot of the digital enzyme-linked immunosorbent assay (ELISA) that powers the Company’s HD-X™ and SR-X™ Ultra-Sensitive Biomarker Detection Systems.
• Entered into a non-exclusive royalty-bearing license agreement with Abbott Laboratories, to grant Abbott access to Quanterix’ portfolio of bead-based technology patents for use in in-vitro diagnostic (IVD) applications.
• Realized multi-category revenue partnership with one of the largest multi-national, healthcare payor groups, with execution of multiple population surveillance studies, creating beachhead for our vision for the future of precision medicine, where early and non-invasive disease detection has the potential to transform life and healthcare costs.
• Successfully raised $97.6 million in gross proceeds through our follow-on offering, further strengthening our balance sheet with growth capital.
• William Geist joined Quanterix as Chief Operating Officer to help us sustain and grown our strong momentum across numerous digital biomarker platforms.
