FY 2025 net product revenues increased 65% to $1,005,000
Current shelf capacity exhausted after raise of $4 million through an ATM facility

WASHINGTON, March 31, 2026 (GLOBE NEWSWIRE) -- 60 Degrees Pharmaceuticals, Inc. (NASDAQ:SXTP, SXTPW)) (the "Company"), a pharmaceutical company focused on developing new medicines for vector-borne disease, reported today its financial results for the 2025 fiscal year ended December 31, 2025.

Financial Highlights for the Fiscal Year Ended December 31, 2025:

Net product revenues increased 65% from $607.6 thousand in 2024 to $1.0 million in 2025, driven by rising sales, price increases, and fewer returns.
The Company achieved a gross profit of approximately $223.8 thousand in 2025, compared with approximately $222.8 thousand in 2024. Gross profit remained relatively stable despite inventory write-offs associated with a final batch of short-dated product entering the supply chain. This charge was a necessary, non-recurring cost incurred as part of scaling operations.
Operating expenses were approximately $8.4 million in 2025, compared with approximately $10.0 million in 2024. The decrease in Research and Development costs of $2.9 million was due to 2024 including $3.2 million of non-cash and non-recurring charges. The increase in general and administrative expenses of $1.3 million was driven primarily by $967.6 thousand in additional sales advisory, advertising and promotion expenses.
Net loss attributable to common shareholders in 2025 was approximately $7.37 million, or $11.73 per share, compared with a net loss of approximately $7.96 million, or $74.17 per share, in 2024 — an improvement of approximately $590 thousand. This improvement was driven primarily by the absence of non-recurring, non-cash Research and Development charges that burdened fiscal year 2024, partially offset by higher selling expenses in fiscal year 2025 and a $1.4 million reduction in the favorable Change in Fair Value of Derivative Liabilities.

Recent Business Highlights:

As of March 30, 2026, the Company had 2,636,788 shares outstanding. In the 12 months through March 27, 2026 the Company had offered and sold approximately $4,026,722 in common shares using its At-the-Market facility, exhausting current baby shelf capacity.
In March 2026, the Company announced that all patients enrolled in its expanded access study for relapsing babesiosis were cured after tafenoquine-based treatment and called for treatment guidelines to be reviewed in light of the new data. The Company believes that the next clinical data release, the interim analysis of its randomized hospital study, could occur as early as late September if recruitment patterns of the 2026 tick season mirror those of the 2025 season.
In February 2026, the Company partnered with GoodRx to provide eligible consumers savings of up to 30% on ARAKODA®, expanding sales footprint to more than 70,000 pharmacies nationwide.
In January 2026, the Company partnered with Runway Health to expand sales of ARAKODA^® for malaria prevention through a travel-focused telehealth platform.
In January 2026, the Company exercised its Florida State University license option for large-scale purification of castanospermine and signaled readiness to commence the regulatory process for Australian Chestnut Extract as a non-prescription botanical product.
In November 2025, the central study site at Mount Sinai opened for patient enrollment in the Phase 2 B-FREE Chronic Babesiosis Study, which is designed to run about 12 months and enroll up to 100 patients.
In July 2025, the Company entered into a sponsored research agreement with Tulane University to evaluate tafenoquine activity against Borrelia (Lyme) and Bartonella bacteria.
In April 2025, the Company announced a patent license agreement with Yale School of Medicine and Yale School of Public Health to jointly advance the development and commercialization of tafenoquine for babesiosis treatment and prevention.
