SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Annual Report on Form 10-K for the year ending December 31, 2024, ("Annual Report") contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). This includes, without limitation, statements regarding the financial position, business strategy, the plans and objectives of management for future operations, statements regarding future economic conditions or performance and statements of belief and any statement of assumptions underlying any of the foregoing. These statements constitute projections, forecasts and forward-looking statements, and are not guarantees of performance. We have based these forward-looking statements on our current expectations and projections about future events. Any statements that refer to projections, forecasts or other characterizations of future events or circumstances are forward-looking statements. In some cases, you can identify forward-looking statements by terminology such as “outlook,” “believes,” “expects,” “potential,” “continues,” “may,” “will,” “should,” “could,” “seeks,” “approximately,” “predicts,” “intends,” “plans,” “estimates,” “anticipates” or the negative version of these words or other comparable words or phrases.

These forward-looking statements are subject to known and unknown risks, uncertainties and assumptions about us that may cause our actual results, levels of activity, performance or achievements to be materially different from any future results, levels of activity, performance or achievements expressed or implied by such forward-looking statements. You should not place undue reliance on these forward-looking statements. Factors that may cause actual results to differ materially from current expectations include, among other things, those listed under Part I, Item 1A, "Risk Factors" of this

Annual Report. In addition, statements that "we believe" and similar statements reflect our beliefs and opinions on the relevant subject. Except as otherwise required by applicable law, we disclaim any duty to update any forward-looking statements, all of which are expressly qualified by the statements in this section, to reflect events or circumstances after the date of this Annual Report. You should read this Annual Report completely and with the understanding that our actual future results, levels of activity and performance as well as other events and circumstances may be materially different from what we expect. We qualify all of our forward-looking statements by these cautionary statements.

Below is a summary of material factors that make an investment in our securities speculative or risky. Importantly, this summary does not address all of the risks and uncertainties that we face. Additional discussion of the risks and uncertainties summarized in this risk factor summary, as well as other risks and uncertainties that we face, can be found in the more detailed discussion in Item 1A in this Annual Report, and the below summary is qualified in its entirety by that more complete discussion of such risks and uncertainties. You should carefully consider the risks and uncertainties described herein as part of your evaluation of an investment in our securities:

•We have a limited operating history, have incurred significant losses since our inception and anticipate incurring increasing expenses and continuing losses for the foreseeable future.

•Our need for additional capital raises substantial doubt about our ability to continue as a going concern. Until we are able to generate significant revenues or achieve profitability through product sales, we will require substantial additional capital to finance our operations and continue development of our product candidates. We cannot be certain that such additional financing will be available on terms favorable to us, or at all, which could limit our ability to grow and jeopardize our ability to continue our business operations.

•The Dynavax Agreement, entered into by Legacy TriSalus in connection with its purchase of nelitolimod requires us to make potentially significant payments to Dynavax before we will have regulatory approval of nelitolimod and be able to generate revenue from sales of nelitolimod.

•We may not be able to generate sufficient cash to service our indebtedness or borrow additional funds pursuant to our Loan Facility.

•Our revenue is primarily generated from sales of our TriNav device and we are therefore highly dependent on it for our success. Failure to achieve continued market acceptance of TriNav for any reason will harm our business and future prospects.

•We currently have a limited marketing, sales and distribution organization. If we are unable to successfully grow our marketing, sales and distribution capabilities, then our product revenues related to TriNav, our results of operations and financial condition will suffer.

•We are early in our pharmaceutical development efforts for nelitolimod, and if we are unable to advance our product candidates, including nelitolimod in clinical development for any reason (including due to lack of funding), obtain regulatory approval and ultimately commercialize our product candidates, or experience significant delays in doing so, our business, results of operations, financial condition, and prospects may be materially adversely affected.

•Clinical development is a lengthy and expensive process with an uncertain outcome. In addition, results of earlier preclinical studies and clinical trials may not be predictive of results of future preclinical studies or clinical trials. Failure can occur at any stage of clinical development.

•Changes in existing third-party coverage or our inability to secure and maintain favorable reimbursement may impact our ability to sell our products, which would materially and adversely impact our business, results of operations, financial condition and prospects.

•The business and industry in which we participate are highly competitive. If we are unable to compete effectively, we will not be able to establish our products in the marketplace or maintain or grow our products’ market share in the marketplace, and as a result, our business and results of operations will be adversely impacted.

•We are subject to numerous complex regulatory requirements, and failure to comply with these regulations, or the cost of compliance with these regulations, may harm our business.

•The complexity of a combination product that includes a drug and a medical device presents additional, unique development and regulatory challenges, which may adversely impact our development plans and our ability to obtain regulatory approval or clearance of our product candidates.

•Failure to obtain, adequately protect, maintain or enforce our intellectual property rights could substantially harm our business and results of operations.

•The expiration or loss of patent protection may adversely affect our future revenues.

•We have limited experience operating as a United States public company and may not be able to adequately develop and implement the governance, compliance, risk management and control infrastructure and culture required for a public company, including compliance with the Sarbanes Oxley Act.

•Our management has identified material weaknesses in its internal control over financial reporting and we may identify additional material weaknesses in the future. If we fail to remediate the material weaknesses or if we otherwise fail to establish and maintain effective control over financial reporting, it may adversely affect our ability to accurately and timely report our financial results and may adversely affect investor confidence and business operations.

•The price of our securities has been and may continue to be volatile.
