Quanterix Corporation (NASDAQ:QTRX), a company fueling scientific discovery through ultrasensitive biomarker detection, today announced financial results for the first quarter ended March 31, 2024.

"Building on the foundation our team developed last year, Quanterix is entering a new innovation and product delivery phase," said Masoud Toloue, Chief Executive Officer of Quanterix. "We've announced the first of several new assays that could re-define the way Tau is measured from the brain versus peripheral sources. We will continue to lead in bringing novel biomarker detection solutions to market for the research community; developing tests to study and enable the early detection of neuro-pathologies such as Multiple Sclerosis, Parkinson's, and Alzheimer's disease."

First Quarter Financial Highlights

Revenue of $32.1 million, an increase of 12.7% compared to $28.5 million in the prior year period.
GAAP gross margin of 61.2%, an increase of approximately 170 basis points compared to the prior year period and non-GAAP gross margin of 54.5%, an increase of approximately 140 basis points compared to the prior year period.
Net loss of $10.1 million, an increase of $4.0 million compared to the corresponding prior year period.
Net cash usage in the quarter was $19.4 million, and the Company ended the period with $304.5 million of cash, cash equivalents, marketable securities, and restricted cash.

Operational and Business Highlights

The Company continues to execute against its transformation initiatives, successfully commercializing five new assays in the quarter.
The Company announced its Simoa^® phospho-Tau 217 (P-tau217) blood test was granted Breakthrough Device designation by the U.S. Food and Drug Administration (FDA) as an aid in diagnostic evaluation of Alzheimer's Disease. The FDA's Breakthrough Device designation is granted to products that have the potential to offer more effective diagnosis of life-threatening diseases with an unmet medical need.
Eli Lilly Clinical Diagnostics Laboratory launched CertuitAD, an in vitro immunoassay that measures plasma tau protein fragments phosphorylated at threonine 217 (P-tau217), using the Quanterix SP-X Imaging and Analysis System™. CertuitAD is intended to be used in patients aged 60 years and older who present with cognitive impairment and who are being evaluated for Alzheimer's disease (AD) and other causes of cognitive decline. CertuitAD is a laboratory developed test (LDT) and is not intended to be used as a screening or stand-alone diagnostic test and is not intended for therapeutic monitoring.

2024 Full Year Business Outlook

The Company's 2024 financial guidance is unchanged. Management continues to expect full-year 2024 revenue in the range of $139 to $144 million. This guide is for the Company's research-only business, and does not include revenues from Diagnostics testing, which to date have not been material. GAAP gross margin percentage is expected to be in the range of 57-61%, and non-GAAP gross margin percentage is expected to be in the range of 51-55%. Finally, the Company continues to anticipate 2024 cash usage in the range of $25 to $30 million.

Use of Non-GAAP Financial Measures

To supplement our financial statements presented on a U.S. GAAP basis, we present non-GAAP gross profit, non-GAAP gross margin, non-GAAP total operating expenses, and non-GAAP loss from operations, which are calculated by including shipping and handling costs for product sales within cost of goods sold instead of within selling, general, and administrative expenses. Management uses these non-GAAP measures to evaluate our operating performance in a manner that allows for meaningful period-to-period comparison and analysis of trends in our business and our competitors. Management believes that presentation of these non-GAAP measures provides useful information to investors in assessing our operating performance within our industry and in order to allow comparability to the presentation of other companies in our industry where shipping and handling costs are included in cost of goods sold for products. The non-GAAP financial information presented here should be considered in conjunction with, and not as a substitute for, the financial information presented in accordance with U.S. GAAP. Set forth below is a reconciliation of non-GAAP gross profit, non-GAAP gross margin, non-GAAP total operating expenses, and non-GAAP loss from operations to their most directly comparable GAAP financial measures.
