T2 Biosystems Announces Preliminary Third Quarter 2023 Financial Results and Business Updates

Received FDA 510(k) clearance for the T2Biothreat Panel and significantly strengthened balance sheet

LEXINGTON, Mass., October 12, 2023 (GLOBE NEWSWIRE)—T2 Biosystems, Inc. (NASDAQ:TTOO) (the “Company”), a leader in the rapid detection of sepsis-causing pathogens and antibiotic resistance genes, today announced preliminary unaudited financial results for the third quarter ended September 30, 2023 and business updates.

Recent Financial and Operational Highlights

• Achieved preliminary third quarter 2023 total revenue of $1.5 million, comprised entirely of product revenue, a decrease of 60% compared to the prior year period, primarily due to a $1.0 million reduction in BARDA revenue.

• Achieved sepsis test panel revenue of $1.1 million, a decrease of 31% compared to the prior year period, primarily due to ending the third quarter with a sepsis test backorder of $380,000.

• Executed contracts for 5 T2Dx Instruments during the third quarter, including 2 in the U.S. and 3 internationally.

• Completed installation for all seven initial T2Dx^® Instruments sold under a multi-year contract with a European distributor for T2Dx Instruments and sepsis test panels for Poland.

• Strengthened balance sheet by converting $10.0 million, or approximately 20%, of term loan debt with CRG Servicing LLC in exchange for shares of T2 Biosystems equity.

• Cash and cash equivalents totaled $24.3 million as of September 30, 2023, and the Company raised an additional $21.9 million in net proceeds through ATM sales during the third quarter.

Recent Pipeline and Clinical Highlights

• Received FDA 510(k) clearance for the T2Biothreat^™ Panel, a direct-from-blood diagnostic test; only FDA-cleared multi-target biothreat test developed/manufactured by a U.S. owned company.

• Received FDA Breakthrough Device designation for Candida auris test, a direct-from-blood molecular diagnostic test, marking the third T2 Biosystems’ product to receive this designation.

• Advanced the T2Resistance Panel toward FDA 510(k) submission, which we expect to occur during the first quarter of 2024.

• Filed FDA 510(k) submission to expand the FDA-cleared T2Bacteria^® Panel to include the detection of Acinetobacter baumannii.

• The Company’s milestone-based product development contract with BARDA ended on September 15, 2023, upon the completion of Option 3.

“Our third quarter results were highlighted by the receipt of FDA 510(k) clearance for the T2Biothreat Panel and 510(k) submission to add Acinetobacter baumannii detection to the FDA-cleared T2Bacteria Panel, which are both intended to create growth opportunities by expanding the test menu on our FDA-cleared T2Dx Instrument,” stated John Sperzel, Chairman and CEO of T2 Biosystems. “Operationally, we have taken aggressive measures to address the sepsis test backorder, we have significantly improved our balance sheet by raising capital and by reducing our debt, and we have taken steps to maintain our Nasdaq listing, all of which will allow the Company to further advance our corporate priorities.”

Preliminary Third Quarter 2023 Financial Results

Total revenue for the third quarter of 2023 was $1.5 million, comprised entirely of product sales, a 60% decrease compared to $3.7 million in the prior year period, driven by a $1.0 million reduction in BARDA revenue, a $0.4 million sepsis test backorder, a $0.3 million reduction in international T2Dx Instrument sales, and a $0.3 million reduction in COVID-19 test sales.

Cash and cash equivalents totaled $24.3 million as of September 30, 2023. The Company raised $21.9 million in net proceeds through ATM sales in the third quarter of 2023 and on July 6, 2023, converted $10 million, or approximately 20%, of its term loan into equity.

The Company’s third quarter 2023 financial results are preliminary and are subject to the completion of the review of the Company’s third quarter 2023 financial statements. Complete third quarter 2023 financial results will be announced in November.

Updated 2023 Financial Outlook

The Company expects fourth quarter sepsis and related product revenue of $2.4 million, representing a sequential quarterly increase of 60% compared to the third quarter of 2023. As a result of the sepsis test backorder, the Company now expects full year total sepsis and related product revenue of $7.5 million, representing a decline of 10% compared to 2022.

Nasdaq Listing Status

The Company regained compliance with Nasdaq market value of listed securities of $35 million on July 6, 2023 and today effected a 1 for 100 reverse stock split intended to regain compliance with Nasdaq minimum bid price rule.
