Insights

TriSalus executes a ~$40M primary equity raise under its shelf.

TriSalus Life Sciences is using its Form S-3 shelf to complete an underwritten offering of 9,756,100 shares at $4.10 per share, with a 1,463,415-share over-allotment option. Gross proceeds are expected to be about $40.0 million, all to the company.

After underwriting discounts of 6.0% per share and other fees, net proceeds are estimated at $37.0 million without the option and $42.64 million if fully exercised. The company cites general corporate purposes, including capital expenditures, working capital, and G&A, so the raise appears geared toward funding ongoing operations and development.

The transaction is fully underwritten by Lake Street Capital Markets and is expected to close on or about February 23, 2026, subject to customary conditions. A 90-day lock-up for the company, officers, directors, and a specified securityholder limits additional equity issuance or insider sales over that period, with actual impact depending on market reception and execution of planned uses of cash.

Pursuant to the terms of the Underwriting Agreement, the Company has also granted the Underwriters a 30-day option to purchase up to an additional 1,463,415 shares of Common Stock (the “Option Shares” and together with the Shares, the “Securities”) to cover over-allotments, if any, at the Offering Price less the underwriting discounts and commissions.

 

Pursuant to the Underwriting Agreement, the Company has agreed to (i) give the Underwriters a discount of 6.0% per Share in the Offering, and (ii) reimburse LSCM for certain of their out-of-pocket expenses incurred in connection with the Offering, including, among other things, the reasonable fees and expenses of counsel, which fees and expenses may not exceed $125,000.

 

The Securities will be issued pursuant to the Company’s shelf registration statement on Form S-3 (File No. 333-291509) filed with the Securities and Exchange Commission (the “Commission”) on November 13, 2025 and declared effective by the Commission on December 4, 2025 and a related prospectus supplement dated February 19, 2026 (the “Prospectus Supplement”).

The offering of such shares is being made only by means of a prospectus supplement that forms a part of the registration statement. A preliminary prospectus supplement and accompanying base prospectus relating to the offering has been or will be filed with the SEC and will be available for free on the SEC’s website at http://www.sec.gov.

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.
