Maintains 2026 revenue guidance of $54 million to $57 million

Hosting Conference Call and Webcast today at 4:30pm ET

TriSalus Life Sciences, Inc. (NASDAQ:TLSI) (the "Company"), an oncology company integrating novel delivery technology with standard of care therapies, and its investigational immunotherapeutic to transform treatment for patients with solid tumors, today announced financial results for the quarter ended June 30, 2026, and provided an operational update.

"We delivered a second quarter marked by year-over-year and strong sequential growth. We continued strengthening our foundation to drive future expansion and adoption of the TriNav platform, and generated clinical evidence that demonstrates and validates the value of our technology," said Mary Szela, President and Chief Executive Officer of TriSalus. "We also wanted to acknowledge the Centers for Medicare and Medicaid Services ("CMS") on the recent establishment of a G-code that extends reimbursement for vascular embolization procedures with the use of a pressure-generating catheter into the physician office-based lab site of service. We look forward to maintaining an active dialogue with CMS as their team finalizes the reimbursement rate in the coming months.

We anticipate seeing further growth in the back half of the year and beyond as our sales team continues to ramp their efforts. We believe the long term growth opportunity for our PEDD platform remains substantial, and see an exciting pathway ahead."

Highlights for Second Quarter 2026 and Recent Weeks

Financial Results for Q2 2026

Revenue from the sale of the TriNav system was $11.4 million for the three months ended June 30, 2026, which was relatively consistent with the prior comparative period with an increase of 1.7% compared to the same period in 2025.
Gross margins were 86.8% for the three months ended June 30, 2026, compared to 83.9% for the same period in 2025. The year-over-year increase in gross margin was primarily due to a reduction in cost per TriNav unit.
Operating losses were $9.8 million for the three months ended June 30, 2026, compared to losses of $7.3 million for the same period in 2025. The increase in operating losses was primarily driven by higher sales and marketing expenses related to our investment in marketing and our sales organization expansion, partially offset by improved gross margins, lower research and development and lower general and administrative expenses.
Net loss available to common stockholders was $9.2 million for three months ended June 30, 2026, compared to a net loss of $9.0 million for the same period in 2025. The current period includes $1.6 million of non-cash net gains related to changes in the fair value of various derivatives for the three months ended June 30, 2026, compared to net gains of $0.4 million for the same period in 2025. The basic and diluted loss per share for three months ended June 30, 2026 was $0.16, compared to $0.27 for the same period in 2025.
The non-GAAP measure of adjusted EBITDA is shown in the table below as the Company believes it is an important measure of performance. Adjusted EBITDA losses were $7.1 million for the three months ended June 30, 2026, compared to losses of $5.3 million for the same period in 2025. The increase in adjusted EBITDA losses were primarily driven by increased sales and marketing expenses, partially offset by improved gross margins, lower research and development and lower general and administrative expenses.
On June 30, 2026, cash and cash equivalents totaled $46.3 million. The Company raised $46.0 million in gross proceeds in the first quarter from an equity offering. The Company believes that these proceeds provide sufficient cash runway to fully fund commercial expansion and pipeline development.

2026 Financial Guidance

The Company is maintaining its full-year 2026 revenue guidance of $54 million to $57 million, consistent with the range set in the first quarter and representing growth of 19% to 26% compared to full year 2025.

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.

Non-GAAP Financial Measure

To supplement the financial results presented in accordance with GAAP, TriSalus has also included in this press release non-GAAP adjusted EBITDA, which excludes from net loss, income tax expense, interest expense, interest income, change in fair value of SEPA, warrant and revenue-base redemption liabilities, change in fair value of contingent earn out liability, stock-based compensation expense and depreciation.
