"Looking ahead to 2026, we intend to deepen our engagement within the interventional radiology community by expanding our sales and commercial organizations, invest in foundational registry and clinical studies to further demonstrate the value of PEDD in the liver and our new applications, and continue to advance innovative PEDD product launches that enhance and differentiate our embolization toolkit. The $46 million in growth capital raised through our recent public offering, will substantially broaden and accelerate these strategic initiatives and drive support broader adoption of the PEDD platform. Based on our performance and positive outlook for 2026, we are reaffirming our revenue guidance of $60 million to $62 million.

Full Year 2025 Financial Results

•Revenue, all from sales of the TriNav system, was $45.2 million for the year ended December 31, 2025, an increase of 53% compared to the same period in 2024. Revenue growth was driven primarily by increased TriNav unit sales within liver directed applications.

•Gross profit increased by $12.9 million for the year ended December 31, 2025, as compared to the year ended December 31, 2024, while gross margin decreased from 86.1% to 84.6% year over year. The increase in gross profit was due primarily to the increase in TriNav units sold, while the year-over-year decline in gross margin was primarily driven by lower manufacturing efficiency associated with newly launched products, which is a dynamic we expect to improve as production scales and processes mature.

•Research and Development (R&D) expenses decreased by $2.7 million or for the year ended December 31, 2025, as compared to the year ended December 31, 2024. The decrease was primarily due to the close-out of clinical trial expenses related to nelitolimod.

•Sales and Marketing (S&M) expenses increased by $2.9 million for the year ended December 31, 2025, as compared to the year ended December 31, 2024. The increase was primarily due to an increase in performance related compensation driven by the increase in sales during the year ended December 31, 2025 compared to prior year.

•General & Administrative (G&A) expenses increased by $3.5 million for the year ended December 31, 2025, as compared to the year ended December 31, 2024. The increase was primarily due to the acceleration of a non-cash stock-based compensation award of approximately $1.8 million, the revision of certain patent-related expenses from research and development to general and administrative expenses of approximately $0.7 million, and professional services as a result of the timing of various filing and audit related expenses.

•Operating losses were $26.9 million, compared to operating losses of $36.2 million for the same period in the prior year. The decrease was primarily driven by the increase in revenue, highlighting strong operating leverage.

•Net loss attributable to common stockholders was $69.7 million in the year ended December 31, 2025, compared to $33.2 million for the same period in the prior year, primarily driven by the conversion of our preferred stock to common stock during the third quarter of 2025, resulting in approximately $30.5 million net loss attributable to common stockholders.

•Improved Adjusted EBITDA to a loss of $17.2 million for the year ended December 31, 2025, compared to a loss of $30.0 million for the year ended December 31, 2024.

•The basic and diluted loss per share was $1.84, compared to $1.31 for the same period in 2024. This increase was primarily due to the conversion of preferred stock to common stock.

The Company anticipates 2026 revenues in the range of $60 million to $62 million.

About TriSalus Life Sciences

TriSalus Life Sciences® is an oncology focused medical technology company seeking to transform outcomes for patients with solid tumors by integrating its innovative delivery technology with standard-of-care therapies, and with its investigational immunotherapeutic, nelitolimod, a class C Toll-like receptor 9 agonist, for a range of different therapeutic and technology applications. The Company's platform includes devices that utilize a proprietary drug delivery technology and a clinical stage investigational immunotherapy. The Company's three FDA-cleared devices use its proprietary Pressure-Enabled Drug Delivery™ (PEDD) approach to deliver a range of therapeutics: the TriNav® Infusion System and TriNav Infusion System LV for hepatic arterial infusion of liver tumors and the Pancreatic Retrograde Venous Infusion System for pancreatic tumors. The PEDD technology is a novel delivery approach designed to address the anatomic limitations of arterial infusion for the pancreas. The PEDD approach modulates pressure and flow in a manner that delivers more therapeutic to the tumor and is designed to reduce undesired delivery to normal tissue, bringing the potential to improve patient outcomes. Nelitolimod, the Company's investigational immunotherapeutic candidate, is designed to improve patient outcomes by treating the immunosuppressive environment created by many tumors and which can make current immunotherapies ineffective in the liver and pancreas. Patient data generated during Pressure-Enabled Regional Immuno-Oncology™ (PERIO) clinical trials support the hypothesis that nelitolimod delivered via the PEDD technology may have favorable immune effects within the liver and systemically. The target for nelitolimod, TLR9, is expressed across cancer types and the mechanical barriers addressed by the PEDD technology are commonly present as well. The Company is in the final stages of data completion for a number of phase 1 clinical trials and will begin exploring partnership opportunities for development.
