Strengthened balance sheet with $46 million equity raise; cash balance of $56.6 million fully funds commercial expansion and pipeline development

Revised 2026 revenue guidance to $54 million to $57 million, reflecting impact of commercial expansion and timing of FDA clearance for TriNav^® Advance

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 March 31, 2026, and provided an operational update.

"The first quarter marked an important strategic inflection point for TriSalus as we significantly strengthened our commercial infrastructure, expanded the clinical evidence supporting PEDD, and continued advancing our next-generation platform opportunities," said Mary Szela, President and Chief Executive Officer of TriSalus. "We are increasingly demonstrating that PEDD is not simply a device, but a differentiated therapeutic delivery platform capable of improving procedural outcomes, reducing healthcare utilization, and expanding treatment possibilities across multiple indications.

During and subsequent to the quarter, we added meaningful new clinical evidence supporting PEDD across liver embolization therapy for liver cancer, and other new embolization applications, including one of the largest real-world analyses ever conducted in interventional oncology. At the same time, we substantially completed the commercial expansion initiatives designed to support our next phase of growth and broader market penetration.

Our updated revenue outlook reflects the lower Q1 revenue from the commercial expansion and the delayed FDA clearance timing for TriNav Advance, our next-generation device which extends PEDD capability to small distal vessels via microcatheter. We continue to believe the long-term growth opportunity for the PEDD platform remains substantial."

Highlights for First Quarter 2026 and Recent Weeks

• Reported publication of Real World PEDD Study of more than 16,800 patients (603 PEDD patients matched against 16,210 non-PEDD patients) published in Journal of Comparative Effectiveness Research, which found PEDD technology was associated with fewer post-procedure complications, reduced hospitalizations, and approximately $7,700 in per-patient charge avoidance despite PEDD patients having greater baseline clinical complexity.
• Presented new clinical and preclinical data at the 2026 Society of Interventional Radiology Annual Scientific Meeting including a preclinical study showing enhanced hepatic tumor penetration during embolic sphere delivery, a clinical analysis of embolization in neuroendocrine tumor liver metastases before and after PEDD, and a clinical assessment of safety and efficacy in uterine artery embolization, further expanding the body of evidence supporting PEDD across multiple applications.
• Reported publication of preclinical research in Frontiers in Oncology demonstrating enhanced delivery and immune activation with nelitolimod delivered with PEDD in liver tumor models.
• Completed a public offering during the quarter, further strengthening the balance sheet with $46 million in gross proceeds and supporting the Company's planned commercial expansion initiatives designed to support long-term growth and broader market opportunity.
• Appointed veteran healthcare investor Michael P. Stansky to the Board of Directors in February 2026.
• Announced the appointment of Richard Marshall, M.D., as Chief Medical Officer effective June 29, 2026.

Financial Results for Q1 2026

• Revenue from the sale of the TriNav system, was $8.9 million for the three months ended March 31, 2026, a decrease of 2.9% compared to the same period in 2025. The decrease in revenue was primarily due to the Company's commercial expansion.
• Gross margins were 86.2% for the three months ended March 31, 2026, compared to 83.7% for the same period in 2025. The year-over-year increase in gross margin was primarily due to lower average cost per TriNav unit.
• Operating losses were $8.4 million for the three months ended March 31, 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 commercial expansion and an increase in non-cash stock-based compensation expense, partially offset by improved gross margins.
• Net income available to common stockholders was $1.5 million for three months ended March 31, 2026, compared to a net loss of $11.1 million for the same period in 2025. The current period includes $11.3 million of non-cash gains related to changes in the fair value of various derivatives for the three months ended March 31, 2026, compared to losses of $1.7 million for the same period in 2025. The basic and diluted earnings (loss) per share for three months ended March 31, 2026, was $0.03, compared to $(0.39) 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 $5.8 million for the three months ended March 31, 2026, compared to losses of $5.5 million for the same period in 2025. The increase in adjusted EBITDA losses were primarily driven by higher stock-based compensation and increased operating expenses.
• On March 31, 2026, cash and cash equivalents totaled $56.6 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.

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.
