Financial Statements and Supplementary Data Table of Contents Page Report of Independent Registered Public Accounting Firm (PCAOB ID: 248 ) 84 Consolidated Balance Sheets 85 Consolidated Statement of Operations 86 Consolidated Statements of Stockholders’ D eficit 87 Consolidated Statements of Cash Flows 88 Notes to Consolidated Financial Statements 90 83 Table of Contents REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM Board of Directors and Stockholders TriSalus Life Sciences, Inc. Opinion on the financial statements We have audited the accompanying consolidated balance sheets of TriSalus Life Sciences, Inc. and subsidiaries (the “Company”) as of December 31, 2025 and 2024, the related consolidated statements of operations, stockholders’ deficit, and cash flows for each of the two years in the period ended December 31, 2025, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2025, in conformity with accounting principles generally accepted in the United States of America. Basis for opinion These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion. Critical audit matters Critical audit matters are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. We determined that there are no critical audit matters. /s/ Grant Thornton LLP We have served as the Company’s auditor since 2024.

Notes to Consolidated Financial Statements (amounts in thousands, except percentages, share and per share data) (1) Nature Of Business On August 10, 2023 (the "Closing Date"), TriSalus Life Sciences, Inc., a Delaware corporation (the “Company,” “TriSalus,” “we,” “us”), formerly known as MedTech Acquisition Corporation (“MTAC”), consummated the previously announced merger pursuant to the Agreement and Plan of Merger by and between MTAC Merger Sub, Inc., a Delaware corporation and wholly-owned subsidiary of MTAC (“Merger Sub”) and TriSalus Operating Life Sciences, Inc. (formerly known as TriSalus Life Sciences, Inc.), a Delaware corporation (“Legacy TriSalus”), whereby Merger Sub merged with and into Legacy TriSalus with the separate corporate existence of Merger Sub ceasing (the “Merger” and, together with the other transactions contemplated by the Merger Agreement, the “Business Combination”). In connection with the consummation of the Business Combination, on August 10, 2023, Legacy TriSalus changed its name from TriSalus Life Sciences, Inc. to TriSalus Operating Life Sciences, Inc., and MTAC changed its name from MedTech Acquisition Corporation to TriSalus Life Sciences, Inc., the surviving company. Legacy TriSalus was deemed to be the accounting acquirer and predecessor company in the Business Combination. We are a growing, oncology focused medical technology business seeking to transform outcomes for patients with solid tumors by integrating our innovative delivery technology with standard-of-care therapies, and with our investigational immunotherapeutic, nelitolimod, a class C Toll-like receptor 9 (“TLR9”) agonist, for a range of different therapeutic and technology applications. Our ultimate goal is to transform the treatment paradigm for patients battling solid tumors. We have developed an innovative technology designed to overcome two significant challenges that prevent optimal delivery and performance of therapeutics in these difficult-to-treat diseases: (i) high intratumoral pressure caused by tumor growth and collapsed vasculature restricting the delivery of oncology therapeutics and (ii) off target delivery. Nelitolimod, specifically, combined with our technology, aims to address the immunosuppressive properties of tumor immune cells in liver, pancreas and other solid tumors. By systematically addressing these barriers, we aim to improve response to therapies and to enable improved patient outcomes. (2) Summary Of Significant Accounting Policies Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”). In management's opinion, the accompanying consolidated financial statements include all adjustments, including normal recurring items, considered necessary for fair presentation. All intercompany accounts and transactions have been eliminated. Certain reclassifications have been made to the 2024 consolidated statements of stockholders’ deficit to conform to the presentation as of December 31, 2025. The accounts of the Company and its wholly owned subsidiaries as of December 31, 2025 and 2024, respectively: TriSalus Operating Life Sciences, Inc., TriSalus Medical LLC and TriSalus Therapeutics LLC. Unless otherwise specified, references to the Company are references to TriSalus Life Sciences, Inc. and its consolidated subsidiaries. Cash, Cash Equivalents and Restricted Cash We consider all highly liquid investments with original maturities of three months or less at the time of purchase to be cash equivalents. We invest excess cash primarily in money market funds. Restricted cash of $ 0.4 million is held in a separate account at our bank to support our corporate credit card program and is recorded in other assets on our consolidated balance sheets. Concentrations of Credit Risk and Other Risks and Uncertainties Our cash is deposited primarily with two Federal Deposit Insurance Corporation (“FDIC”) insured financial institutions. At times, the deposits in these institutions may exceed the amount of insurance provided on such deposits. Although we have not experienced any losses in such accounts and believe that we are not exposed to any significant risk on these balances, bank failures, events involving limited liquidity, defaults, non-performance, or other adverse developments that affect financial institutions, or concerns or rumors about such events, may lead to liquidity constraints. 90 Table of Contents Accounts Receivable and Customer Concentrations Accounts receivable are recorded at the invoiced amount and do not bear interest. Our payment terms are typically on net 30 day terms. Our accounts receivables balances were $ 6.6 million and $ 5.1 million as of December 31, 2025 and 2024 and $ 3.6 million as of January 1, 2024, respectively. In accordance with ASC Topic 326, Financial Instruments-Credit Losses , the allowance for credit losses is our best estimate of the amount of probable credit losses in our existing accounts receivable. We review our allowance for credit losses periodically and establish reserves based on management’s expectations of realization based on historical write-off experience, as well as current general economic conditions and expectations regarding collection. Account balances are charged against the allowance after all reasonable means of collection have been exhausted and the potential for recovery is considered remote. The following table summarizes the allowance for credit losses accounts activity for the year ended December 31, 2025: December 31, 2025 Beginning Balance $ 187 Amount charged (reversed) to costs and expenses ( 103 ) Write-off of uncollectible receivables ( 60 ) Ending Balance $ 24 Inventory Inventory is carried at the lower of cost or net realizable value. The balances are recorded on the first-in first-out method. Raw materials consist of purchase material, completed sub-assemblies and parts for general production use. Finished goods consist of completed products, including direct labor and manufacturing overhead. Write-downs for excess and obsolete inventory are charged to cost of goods sold in the period when conditions giving rise to the write-downs are first recognized. Valuation reserves are recorded when, in our best judgment, we determine the carrying value of the affected inventory may be impaired or its net realizable value exceeds its cost. Use of Estimates The preparation of the consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ significantly from those estimates. The most significant estimates relate to the valuation of the OrbiMed warrant liabilities (see Note 8), the contingent earnout liability (see Note 7), the revenue base redemption liability (see Note 12) and the valuation allowance on deferred tax assets (see Note 9). Property and Equipment Property and equipment are recorded at cost. Repairs and maintenance costs are expensed as incurred. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets. The approximate useful life of each class of property and equipment is as follows: Useful Life (Years) Machinery and equipment 5  –  7 Computers and software 2  –  3 Furniture 5 Leasehold improvements Lesser of estimated useful lives of the assets or the lease term Other property 7 91 Table of Contents Leases We account for leases in accordance with Accounting Standards Codification (“ASC”) Topic 842, Leases . We determine if an arrangement is or contains a lease at contract inception, and, if it does, the lease is recorded on the consolidated balance sheets with right-of-use assets (“ROU”) representing the Company’s right to use an underlying asset for the lease term, and lease liabilities representing our obligation to make lease payments. Lease ROU assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. Lease ROU assets also include the effect of any lease payments made prior to or on lease commencement and excludes lease incentives and initial direct costs incurred, as applicable. As the implicit rate in our leases is typically unknown, we use our incremental borrowing rate based on the information available at the lease commencement date in determining the present value of future lease payments. When calculating our incremental borrowing rate, we consider our credit risk, the term of the lease and total lease payments and adjusts for the impacts of collateral as necessary. The lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. To determine the expected lease term, we excluded all options as it is not reasonably certain we would exercise these options. Lease expense is recognized on a straight-line basis over the lease term. We have elected to not separate lease and non-lease components for any leases within our existing classes of assets and, as a result, account for any lease and non-lease components as a single lease component. The Company has made an accounting policy election applicable to all asset classes not to record leases with an initial term of twelve months or less on the balance sheet as allowed within ASC 842. For operating and finance leases, the lease liability is initially measured at the present value of the unpaid lease payments at the lease commencement date. The lease liability is subsequently measured at amortized cost using the effective-interest method. The ROU asset is initially measured at cost, which comprises the initial amount of the lease liability adjusted for lease payments made at or before the lease commencement date, plus any initial direct costs incurred less any lease incentives received. For operating leases, the ROU asset is subsequently measured throughout the lease term at the carrying amount of the lease liability, plus initial direct costs, plus (minus) any prepaid (accrued) lease payments, less the unamortized balance of lease incentives received. Lease expense for lease payments is recognized on a straight-line basis over the lease term. For finance leases, the ROU asset is subsequently amortized using the straight-line method from the lease commencement date to the earlier of the end of its useful life or the end of the lease term unless the lease transfers ownership of the underlying asset to the Company or the Company is reasonably certain to exercise an option to purchase the underlying asset. In those cases, the ROU asset is amortized over the useful life of the underlying asset. Amortization of the ROU asset is recognized and presented separately from interest expense on the lease liability. Finance lease ROU assets are presented with property and equipment, net in the consolidated balance sheets. Warrant Liabilities Freestanding financial instruments that permit the holder to acquire shares that are either puttable by the holder, redeemable or contingently redeemable are required to be reported as liabilities in the consolidated financial statements. We present such liabilities on the consolidated balance sheets at their estimated fair values. Changes in fair value of the liability are calculated each reporting period and any change in value is recognized in the consolidated statements of operations. In connection with the Business Combination, we assumed warrants to purchase Common Stock. The warrants include the Public Warrants, Private Placement Warrants and Working Capital Warrants (the "Exchange Warrants"). We value the liability for all of the warrants based on the trading price of the publicly held warrants. See Notes 3 and 8 for further discussion. In connection with our borrowing under the Initial OrbiMed Credit Agreement, we issued the Initial OrbiMed Warrant, which we classified as a derivative liability because it did not meet the equity classification criteria under ASC 815-40. We calculated the fair value of the Initial OrbiMed Warrant based on the Black-Scholes-Merton option valuation model (“Black-Scholes”). This model considers several variables and assumptions in estimating the fair value of financial instruments, including the per-share fair value of the underlying common stock, exercise price, expected term, risk-free interest rate, expected stock price volatility over the expected term and expected annual dividend yield. See Notes 3 and 8 for further discussion. 92 Table of Contents Revenue Base Redemption Liability In connection with our the Initial OrbiMed Loan, if a “Product Revenue Base” (i.e., with respect to any period, the net revenues for such period from sales of TriNav) on a trailing 12-month basis does not equal or exceed the specified amounts, we will start repaying the outstanding principal amount of the loans under the OrbiMed Credit Agreement. These required revenue thresholds are referred to as the “revenue base redemption liability." We determined that we should bifurcate and separately recognize the revenue base redemption liability. We determined the value of the revenue base redemption liability using a Monte Carlo simulation of future revenue and valuing the Initial Term Loan using the with and without method. The change in fair value of the liability is recorded in the consolidated statement of operations. See Note 12 for further detail. Contingent Earnout Liability In connection with the execution of the Merger Agreement, MTAC entered into a sponsor support agreement (the “Sponsor Support Agreement”) with MedTech Acquisition Sponsor LLC (the "Sponsor”), Legacy TriSalus and MTAC’s directors and officers (the Sponsor and MTAC’s directors and officers, collectively, the “Sponsor Holders”). Pursuant to the Sponsor Support Agreement, 3,125,000 shares of common stock in the Company ("Common Stock") held by the Sponsor Holders immediately after the Closing Date (such shares, the “Sponsor Earnout Shares”) became unvested and subject to potential forfeiture if certain triggering events are not achieved prior to the fifth anniversary of the Closing Date (the “Earnout Period”). The Sponsor Earnout Shares are classified as a liability in the Company’s consolidated balance sheets because they do not qualify as being indexed to the Company’s own stock. The earnout liability was initially measured at fair value at the Closing Date using a Monte Carlo simulation of our future stock price and is subsequently remeasured at the end of each reporting period. The change in fair value of the earnout liability is recorded in the consolidated statements of operations. See Notes 3 and 7 for further detail. Standby Equity Purchase Agreement In October 2023, the Company entered into a SEPA with Yorkville, which expired November 1, 2025. Pursuant to the SEPA, the Company had the right, but not the obligation, to sell to Yorkville up to $ 30.0 million of shares of Common Stock at the Company’s request any time during the 24 months following the execution of such purchase agreement, subject to certain conditions. The SEPA, in its entirety, was not classified as a liability pursuant to ASC 480, and was accounted for as a derivative pursuant to ASC 815-10, Derivatives and Hedging ("ASC 815-10"). The SEPA was valued based on a scenario-based valuation model utilizing the expected draws, probability of the draws and risk-free rate inputs. The change in the fair value was recorded in the consolidated statements of operations. See Note 11 for further detail. Impairment and Disposal of Long-Lived Assets We review long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is generally measured by a comparison of the carrying amount of the asset to future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amounts of the assets exceed the estimated fair values of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less cost to sell. Stock-Based Compensation We account for all employee stock-based compensation awards by recording expense based on the estimated fair value of the awards at the time of grant using the Black-Scholes option pricing model for stock options and price of our common stock on the grant date for restricted stock units ("RSUs") and performance stock units ("PSUs"). The determination of fair value using an option-pricing model is affected by the estimated fair value of the Company’s stock, as well as assumptions regarding a number of variables including, but not limited to, the fair value of underlying stock at the grant date, expected term of the awards, expected volatility of the underlying stock over the term of the awards, and risk-free interest rates. We have elected to not include an estimated forfeiture rate in our stock-based compensation expense recognition, in accordance with ASC Topic 718, Compensation — Stock Compensation , and we account for forfeitures in the period in which they occur. The estimated fair value of options, RSUs and PSUs granted are recognized as compensation expense on a straight-line basis over the expected life for each separately vesting portion of the awards. All shares issued upon the exercise of stock options and vesting of RSUs and PSUs are from our reserved authorized common stock. We record the issuance of shares when they are recorded by the transfer agent and, as such, there could be timing differences between when the expense is recorded and shares are transferred. 93 Table of Contents Revenue Recognition Our revenue is derived from the shipments of our PEDD infusion systems to our customers. Our customers are generally comprised of hospitals and clinics. Under ASC Topic 606, Revenue Recognition , we evaluate five steps to determine the appropriate timing and amount to recognize revenue. The five steps are: 1. Identify the contract — We do not maintain long-term contracts with our customers. Typically, customers will submit a purchase order to us for delivery of a quantity of our products, which incorporate enforceable rights and obligations constituting the contract with the customer. 2. Identify the performance obligation — Our performance obligation is to deliver the ordered products in accordance with the terms of the purchase order, which constitutes a single performance obligation. We do not have any on-going service obligation after delivery and only offer our customers an assurance-type warranty, which provides assurance the product will work as intended. 3. Determine the transaction price — We maintain a single sales price for each of our products, which is generally fixed. For customers with rebate or discount agreements, the rebates and discounts are accounted for within a contra-revenue account at the time the rebate milestone is achieved or discount is given. We do not have a history of any significant refunds, allowances or other concessions provided to our customers from the agreed-upon sales price after delivery of the product. Refunds, allowances or other concessions are accounted for as a reduction of revenue. 4. Allocate the transaction price — We do not have multiple performance obligations to complete when we fulfill a purchase order, as such, the transaction price is allocated fully to the units being sold. 5. Recognize revenue — We recognize revenue at the point-in-time when the units for a purchase order have been shipped and control of the units has transferred to the customer, as evidenced by the delivery terms on the shipping documents. Typically, we ship Freight on Board (FOB) Shipping Point. Therefore, we recognize revenue when the shipment leaves our premises. In certain cases, the purchase order specifies alternate shipping terms, usually FOB destination. In those cases, we defer revenue recognition until we are assured the units have been delivered and control has transferred to the customer. Our sale team is able to make in-person sales. When this occurs, the revenue in not recognized until we receive a Purchase Order ("P.O.") from the customers, with the inventory treated as consignment until the time receiving the P.O. Shipping and handling activities are not considered to be a separate performance obligation. Therefore, the costs are considered to be a fulfillment cost and the expenses are accounted for within cost of goods sold. We provide certain customers with rebates that are explicitly stated in our contracts and are recorded as a reduction of revenue in the period the conditions for the rebates are achieved. The rebates result from performance-based offers that are primarily based on attaining contractually specified sales volumes. Subsequent to a rebate being earned, the customer receives a credit to apply to future purchases. We recognized $ 1.0 million and $ 0.3 million of rebates for the years ended December 31, 2025 and 2024, respectively. Research and Development Research and development (“R&D”) costs include our engineering, regulatory, pre-clinical and clinical activities. R&D costs are expensed as incurred. The costs are related to internal headcount and external services we purchase, such as pre-clinical supplies and materials, clinical study management and supplies, and consulting related to our R&D. There were no development milestone payments to Dynavax for nelitolimod during the years ended December 31, 2025 and 2024 (see Note 10). In 2021, we entered into a 5-year Alliance Program (the “MDACC Agreement”) with the University of Texas MD Anderson Cancer Center (“MDACC”) to serve as the lead investigators for the PERIO-01, PERIO-02, and PERIO-03 studies. The term of the agreement was for the later of (i) five years or (ii) until the applicable studies are completed. Prior to the expiration of the term of the MDACC Agreement, either party may terminate the MDACC Agreement if the other party commits a material breach of the agreement and fails to cure such breach within 30 days of receiving notice of such breach. Effective February 25, 2025, we modified our payment terms and extended the MDACC Agreement for an additional year. 94 Table of Contents We are required to estimate our expenses resulting from our obligations under agreements with vendors, consultants, and contract research organizations, in connection with conducting R&D activities. The financial terms of these contracts are subject to negotiations, which vary from agreement to agreement and may result in payment flows that do not match the periods over which goods or services are provided. We reflect R&D expenses in our consolidated financial statements by matching those expenses with the period in which services and efforts are expended. We account for these expenses according to the progress of the agreements, along with preparation of financial models, taking into account discussions with research and other key personnel as to the progress of studies or other services being performed. To date, we have had no material differences between our estimates of such expenses and the amounts actually incurred. Nonrefundable advance payments for goods and services are deferred and recognized as expense in the period that the related goods are consumed or services are performed. With the close out of some of our clinical studies related to nelitolimod, we recorded a charge of approximately $ 2.1 million during the year ended December 31, 2025. Segment Reporting Our Chief Operating Decision Maker (“CODM”), the Chief Executive Officer ("CEO"), reviews our financial information on a consolidated basis for purposes of allocating resources and evaluating its financial performance. The CEO considers recommendations from the Chief Financial Officer ("CFO") and reviews the Monthly Financial Report ("MFR"), including financial information and the Company’s performance highlights, such as revenue, accounts receivable and inventory balances, cash flows and cash on-hand, operational expenditures and headcount. Based on the Company’s consolidated financial information, the CEO makes the key operating decisions and determines how resources should be allocated. Once the CEO has decided, the CEO and CFO are responsible for carrying out the CEO’s decisions. All of our customers and long-lived assets are located in the United States. Since the Company operates as a single reporting segment, all required segment reporting disclosures can be found in the consolidated financial statements. Accordingly, we have determined we operate as a single reportable segment within a single geographic area. Advertising Advertising expense, which is included in sales and marketing costs, is expensed as incurred. Expense for the years ended December 31, 2025 and 2024, was $ 1.4 million and $ 0.5 million, respectively. Income Taxes We account for income taxes pursuant to ASC Topic 740, Income Taxes , which requires the use of the asset-and-liability method of accounting for deferred income taxes. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. A valuation allowance is recorded to the extent it is more likely than not that a deferred tax asset will not be realized. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in operations in the period that includes the enactment date. The Company recognizes the effect of income tax positions when it is more likely than not, based on technical merits, that the position will be sustained upon examination. Through 2025, management determined that no uncertain tax positions have been taken or are expected to be taken that could have a material effect on the Company’s income tax liabilities. Recently Adopted Accounting Pronouncements In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures . Under the ASU, Public Business Entity ("PBE") must annually "(1) disclose specific categories in the rate reconciliation and (2) provide additional information for reconciling items that meet a quantitative threshold (if the effect of those reconciling items is equal to or greater than 5% of the amount computed by multiplying pretax income or loss by the applicable statutory income tax rate)." This guidance is effective for public companies for annual periods beginning after December 15, 2024. The Company adopted this guidance during the most recent fiscal year (see Note 9). 95 Table of Contents In March 2024, the FASB issued ASU 2024-01, Compensation - Stock Compensation (Topic 718): Scope Application of Profits Interest and Similar Awards, which clarifies the guidance on ASC Topic 718 by illustrating how to apply the scope guidance to determine whether a profit interest award should be accounted for as a shared-based payment arrangement under ASC 718 or another accounting standard (e.g., employee profit-sharing arrangement under ASC 710). The ASU aims to reduce the complexity diversity in practice by adding an example to ASC 718 that describes four fact patterns and illustrates how an entity evaluates common terms and characteristics of profit interests and similar awards to reach a conclusion about whether an award meets the scope conditions in ASC 718-10-15-3. The ASU is effective for all public entities for fiscal years beginning after December 15, 2024 and interim periods within those fiscal years. We adopted ASU 2024-01 on January 1, 2025. The effect of the adoption had no impact on our consolidated financial statements. In March 2024, the FASB issued ASU 2024-02, Codification Improvements — Amendments to Remove References to the Concept Statements, which removes references to the Board's concepts statement from the FASB Accounting Standards Codification (the "Codification" or ASC). The ASU is part of the Board’s standing project to make “Codification updates for technical corrections such as conforming amendments, clarifications to guidance, simplifications to wording or the structure of guidance, and other minor improvements.” Before establishing the Codification in 2009, the FASB used or referred to the concepts statements as part of its standard setting. However, the Board is now removing those references since “references to the Concepts Statements in the Codification could imply that the Concepts Statements are authoritative." The amendment is effective for all public entities for fiscal years beginning after December 15, 2024. Those who adopt the amendments in an interim period would have to adopt them as of the beginning of the fiscal year that includes that interim period. We adopted ASU 2024-02 on January 1, 2025. The effect of the adoption had no impact on our consolidated financial statements. Accounting Pronouncements Not Yet Adopted In October 2023, the FASB issued ASU No. 2023-06, D isclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative . The amendments in ASU 2023-06 update requirements in various disclosure areas, including the statement of cash flows, earnings per share, debt and equity. The amendments in ASU 2023-06 will be effective on the date the related disclosures are removed from Regulation S-X or Regulation S-K by the SEC and will no longer be effective if the SEC has not removed the applicable disclosure requirement by June 30, 2027. Early adoption is prohibited. We are currently evaluating the impact the adoption of this ASU will have on our consolidated financial statements. In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses , and in January 2025, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date. ASU 2024-03 requires additional disclosure of the nature of expenses included in the income statement as well as disclosures about specific types of expenses included in the expense captions presented in the income statement. ASU 2024-03, as clarified by ASU 2025-01. The amendment applies to all public business entities and is effective for annual reporting periods beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027. The requirements will be applied prospectively with the option for retrospective application. Early adoption is permitted. We are currently evaluating the impact the adoption of this ASU will have on our consolidated financial statements. In November 2024, the FASB issued ASU 2024-04, Debt - Debt with Conversion and Other Options (Subtopic 470-20): Induced Conversions of Convertible Debt Instruments , which amends ASC 470-20, Debt: Debt With Conversion and Other Options , to clarify the requirements related to accounting for the settlement of a debt instrument as an induced conversion. Based primarily on the consensus-for-exposure reached on Issue 23-A, Induced Conversion of Convertible Debt Instruments, by the Emerging Issues Task Force on September 14, 2023. The ASU is intended to “improve the relevance and consistency in application of the induced conversion guidance in Subtopic 470-20 for (a) convertible debt instruments with cash conversion features and (b) debt instruments that are not currently convertible.” The amendments are effective for all entities for annual reporting periods beginning after December 15, 2025, and interim reporting periods within those annual reporting periods. Early adoption is permitted as of the beginning of the annual reporting period for all entities that have adopted the amendments in Update 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. We are currently evaluating the impact the adoption of this ASU will have on our consolidated financial statements. 96 Table of Contents In May 2025, the FASB issued ASU 2025-04, Compensation - Stock Compensation and Revenue from Contracts with Customers , which clarifies the guidance for accounting for stock-based payments to customers, including the treatment of vesting conditions tied to customer purchases and the requirement to estimate forfeitures. ASU 2025-04 will become effective for us for annual periods beginning after December 15, 2026, with early adoption permitted. We are currently evaluating the impact the adoption of this ASU will have on our consolidated financial statements. In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements , which clarifies the applicability of interim reporting guidance and interim disclosure requirements under ASC Topic 270, including the addition of a disclosure principle requiring disclosure of material events occurring since the most recent annual reporting period. ASU 2025-11 will become effective for us for interim periods within annual periods beginning after December 15, 2027, with early adoption permitted. We are currently evaluating the impact the adoption of this ASU will have on our consolidated financial statements. In December 2025, the FASB issued ASU 2025-12, Codification Improvements , which makes targeted amendments to various topics within the ASC intended to clarify existing guidance and correct minor inconsistencies. ASU 2025-12 will become effective for us for annual periods beginning after December 15, 2026, with early adoption permitted. We are currently evaluating the impact the adoption of this ASU will have on our consolidated financial statements. (3) Financial Instruments Our financial instruments consist of warrant liabilities, the contingent earnout liability, a Standby Equity Purchase Agreement ("SEPA"), and the revenue based redemption liability related to the Credit Agreement we entered into with OrbiMed (the "OrbiMed Credit Agreement"). The carrying values of cash and cash equivalents, accounts receivable, net and trade payables approximate fair value through the use of publicly available market prices as of December 31, 2025 and 2024. In general, asset and liability fair values are determined using the following categories: Level 1 — Inputs utilize quoted prices in active markets for identical assets or liabilities. Level 2 — Inputs include quoted prices for similar assets or liabilities in active markets, and inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. Level 3 — Inputs are unobservable inputs and include situations where there is little, if any, market activity for the balance sheet items at period end. Pricing inputs are unobservable for the terms and are based on the Company’s own assumptions about the assumptions that a market participant would use. Our contingent earnout liability, warrant liabilities, SEPA liability and revenue base redemption liability are measured at fair value on a recurring basis (see Notes 7, 8, 11, and 12, respectively). The carrying values of the warrant liabilities represent the remeasurement to fair value each reporting period based on Level 1 inputs for the publicly traded Public Warrants and Level 2 inputs for the Private Placement Warrants and Working Capital Warrants. The carrying amounts of the OrbiMed Warrants (defined in Note 8), contingent earnout liability and SEPA liability represent the remeasurement to fair value each reporting period based on unobservable, or Level 3 inputs, using assumptions made by us, including the market price of our common stock and the observed volatility of a peer group companies. The fair value of the Public Warrants has been measured based on the quoted price of such warrants on the Nasdaq Global Market (the "Nasdaq"). The Private Placement Warrants and Working Capital Warrants are similar to the Public Warrants and, therefore, use the same fair value as the Public Warrants (see Note 8). We use a Black-Scholes option pricing model to estimate the fair value of the OrbiMed Warrants (defined in Note 8), as warrants give the holders the right, but not the obligation, to purchase the underlying securities at a contractual exercise price. This method utilizes certain unobservable inputs, including the determination of the expected volatility, and is therefore considered a Level 3 fair value measurement. Certain inputs used in this Black-Scholes pricing model may fluctuate in future periods based upon factors that are outside of our control, including a potential change in control. A significant change in one or more of these inputs used in the calculation of the fair value may cause a significant change to the fair value of the warrant liabilities, which could also result in material non-cash gains or losses being reported in the consolidated statement of operations. The expected volatility was implied from a blend of the Company's own common shares and the average historical share volatilities of several public companies within the Company's industry that the Company considers to be comparable to its own business. 97 Table of Contents The estimated fair value of the contingent earnout liability was determined using a Monte Carlo simulation valuation model using a distribution of potential outcomes. The inputs and assumptions utilized in the calculation require management to apply judgment and make estimates as further described in Note 7. The repayment of the loans under the OrbiMed Credit Agreement is referred to as the "revenue base redemption liability" (see Note 12). We determine the value of the revenue base redemption liability using a Monte Carlo simulation of future revenue and valuing the Term Loan (as defined in Note 12) using the with and without method. The following tables summarize the changes in fair value of our outstanding warrant liabilities, contingent earnout liability, SEPA liability and revenue base redemption liability for the year ended December 31, 2025: Warrant Liabilities Fair Value at December 31, 2024 Change in Fair Value (Gains) Losses Issuances (Settlements) Fair Value at December 31, 2025 Public Warrants - Level 1 $ 1,927 $ 981 $ — $ 2,908 Private Placement Warrants - Level 2 $ 4,872 $ 2,480 $ — $ 7,352 Working Capital Warrants - Level 2 $ 1,100 $ 560 $ — $ 1,660 Level 3 Liabilities Fair Value at December 31, 2024 Change in Fair Value (Gains) Losses Issuances (Settlements) Fair Value at December 31, 2025 Contingent earnout liability $ 7,401 $ 2,743 $ — $ 10,144 SEPA liability $ 55 $ ( 55 ) $ — $ — OrbiMed Warrant liability $ 362 $ 244 $ 366 $ 972 Revenue base redemption liability $ 507 $ ( 124 ) $ — $ 383 The following tables summarize the changes in fair value of our outstanding warrant liabilities, contingent earnout liability, SEPA liability and revenue base redemption liability for the year ended December 31, 2024: Warrant Liabilities Fair Value at December 31, 2023 Change in Fair Value (Gains) Losses Issuances (Settlements) Fair Value at December 31, 2024 Public Warrants - Level 1 $ 9,855 $ 3,140 $ ( 11,068 ) $ 1,927 Private Placement Warrants - Level 2 $ 5,871 $ ( 144 ) $ ( 855 ) $ 4,872 Working Capital Warrants - Level 2 $ 1,190 $ ( 90 ) $ — $ 1,100 Level 3 Liabilities Fair Value at December 31, 2023 Change in Fair Value (Gains) Losses Issuances (Settlements) Fair Value at December 31, 2024 Contingent earnout liability $ 18,632 $ ( 11,231 ) $ — $ 7,401 SEPA liability $ 185 $ ( 130 ) $ — $ 55 OrbiMed Warrant liability $ — $ ( 449 ) $ 811 $ 362 Revenue base redemption liability $ — $ ( 222 ) $ 729 $ 507 98 Table of Contents (4) Inventory The components of inventory are summarized as follows: December 31, 2025 December 31, 2024 Raw materials $ 1,289 $ 1,338 Finished goods 1,897 2,720 Reserve for obsolete inventory ( 109 ) ( 10 ) Inventory, net $ 3,077 $ 4,048 (5) Property And Equipment Property and equipment, net consists of the following: December 31, 2025 December 31, 2024 Machinery and equipment $ 1,952 $ 2,636 Computers and software 1,094 1,279 Furniture 163 425 Leasehold improvements 1,571 772 Other property 13 13 Construction in progress 248 331 Gross property and equipment 5,041 5,456 Less accumulated depreciation ( 3,233 ) ( 3,787 ) Property and equipment, net $ 1,808 $ 1,669 Depreciation expense for property and equipment for the years ended December 31, 2025 and 2024, was $ 0.6 million and $ 0.7 million, respectively. (6) Accrued Liabilities Accrued liabilities consists of the following: December 31, 2025 2024 Accrued liabilities - clinical $ 1,090 $ 2,297 Accrued incentives 1,920 2,094 Accrued liabilities - general 2,390 1,850 Accrued vacation 401 362 Accrued payroll 2,195 718 Accrued taxes 100 34 Total Accrued Liabilities $ 8,096 $ 7,355 Accrued liabilities - general includes accruals from our services providers and other miscellaneous operating accruals. 99 Table of Contents (7) Contingent Earnout Liability In connection with the Business Combination, MTAC entered into a sponsor support agreement (the "Sponsor Support Agreement"). Pursuant to the Sponsor Support Agreement, the 3,125,000 Sponsor Earnout Share (the "Sponsor Earnout Shares") become unvested and subject to potential forfeiture if certain triggering events are not achieved prior to the fifth anniversary of the Closing Date. Pursuant to the Sponsor Support Agreement, for any 20 trading days within a period of 30 consecutive trading days, (i) 25 % of the shares of the unvested Common Stock held by the Sponsor Holders will vest if the volume weighted average price of our Common Stock equals or exceeds $ 15.00 , (ii) 25 % of the shares of the unvested Common Stock held by the Sponsor Holders will vest if the volume weighted average price of our Common Stock equals or exceeds $ 20.00 , (iii) 25 % of the shares of the unvested Common Stock held by the Sponsor Holders will vest if the volume weighted average price of our Common Stock equals or exceeds $ 25.00 , and (iv) 25 % of the shares of the unvested Common Stock held by the Sponsor Holders will vest if the volume weighted average price of our Common Stock equals or exceeds $ 30.00 . Additionally, the Sponsor Earnout Shares will vest if there is a change in control of our company on or before the fifth anniversary of the Closing Date that results in the holders of our Common Stock receiving a price per share equal to or in excess of the applicable earnout targets. Any such shares held by the Sponsor Holders that remain unvested after the fifth anniversary of the Closing Date will be forfeited. The liability was remeasured to its fair value of $ 10.1 million and $ 7.4 million as of December 31, 2025 and 2024, respectively, based on a Monte Carlo simulation valuation model. This remeasurement resulted in recording a loss of $ 2.7 million and a gain of $ 11.2 million for the years ended December 31, 2025 and 2024, respectively, classified as change in fair value of contingent earnout liability in the consolidated statements of operations. Assumptions used in the valuation are described below: December 31, 2025 December 31, 2024 Current stock price $ 6.98 $ 5.01 Expected share price volatility 70.0 % 70.0 % Risk-free interest rate 3.5 % 4.3 % Expected term (years) 2.6 3.6 Estimated dividend yield — % — % The estimated fair value of the liability was determined using a Monte Carlo simulation valuation model using a distribution of potential outcomes. The inputs and assumptions utilized in the calculation require management to apply judgment and make estimates including: (a) expected volatility, which is based on the historical equity volatility of publicly traded peer companies for a term equal to the expected term of the earnout period; (b) expected term, which we based on the earnout period per the agreement; (c) risk-free interest rate, which was determined by reference to the U.S. Treasury yield curve for time periods commensurate with the expected term of the earnout period; and (d) expected dividend yield, which we estimate to be 0 % based on the fact that we have never paid or declared dividends. These estimates may be subjective in nature and involve uncertainties and matters of judgment and therefore cannot be determined with exact precision. 100 Table of Contents (8) Warrants Warrants that have not been tendered for exchange and outstanding at December 31, 2025 and December 31, 2024, are as follows: December 31, 2025 December 31, 2024 Public Warrants 1,751,825 1,751,825 Private Placement Warrants 4,428,648 4,428,648 Working Capital Warrants 1,000,000 1,000,000 OrbiMed Warrants 222,068 130,805 Total warrants 7,402,541 7,311,278 Public, Private Placement and Working Capital Warrant Liabilities In connection with consummation of the Business Combination, the Company assumed the warrant liabilities associated with 8,333,272 Public Warrants. Each Public Warrant is exercisable to purchase one share of common stock at a price of $ 11.50 per share, subject to adjustment. As of December 31, 2025 and 2024, there were 1,751,825 Public Warrants outstanding. The Public Warrants expire on August 10, 2028 or earlier upon redemption or liquidation. The Public Warrants expire five years after the completion of the Business Combination or earlier upon redemption or liquidation. We may redeem for cash the outstanding Public Warrants: a. in whole and not in part; b. at a price of $ 0.01 per Warrant; c. upon not less than 30 days’ prior written notice of redemption to each warrant holder; and d. if, and only if, the reported closing price of the Common Stock equals or exceeds $ 18.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within a 30 trading day period ending three business days before the Company sends the notice of redemption to the warrant holders. If and when the Public Warrants become redeemable, we may exercise its redemption right even if it is unable to register or qualify the underlying securities for sale under all applicable state securities laws. If we call the Public Warrants for redemption, management will have the option to require all holders that wish to exercise the Public Warrants to do so on a cashless basis. The exercise price and number of shares of common stock issuable upon exercise of the warrants may be adjusted in certain circumstances including in the event of a stock dividend, or recapitalization, reorganization, merger or consolidation. However, except as described below, the warrants will not be adjusted for issuances of common stock at a price below its exercise price. Additionally, in no event will we be required to net cash settle the warrants. Accordingly, the warrants may expire worthless. In addition to the Public Warrants, we assumed the warrant liabilities associated with 4,933,333 Private Placement Warrants and 1,000,000 Working Capital Warrants. The Private Placement Warrants and Working Capital Warrants are identical to the Public Warrants, except that the Private Placement Warrants and Working Capital Warrants, and the common stock issuable upon the exercise of the Private Placement Warrants and Working Capital Warrants, were not transferable, assignable or saleable until 30 days after the completion of the Business Combination, subject to certain limited exceptions. Additionally, the Private Placement Warrants and Working Capital Warrants are exercisable on a cashless basis and are non-redeemable so long as they are held by the initial purchasers or their permitted transferees. If the Private Placement Warrants and Working Capital Warrants are held by someone other than the initial purchasers or their permitted transferees, they will be redeemable by the Company and exercisable by such holders on the same basis as the Public Warrants. As of December 31, 2025 and 2024, there were 4,428,648 Private Placement Warrants and 1,000,000 Working Capital Warrants outstanding. We determined that the Public Warrants, Private Placement Warrants and Working Capital Warrants do not meet the criteria to be equity classified and should be recorded as liabilities. Our analysis concluded liability classification under ASC 815, Derivatives and Hedging , as these warrants include a provision that could allow cash settlement upon an event outside our control, and such event may not result in a change in control of the Company. As a result, the Public Warrants, Private Placement Warrants, and Working Capital Warrants do not meet the criteria for equity classification. 101 Table of Contents As of December 31, 2025, the fair values of the Public Warrants, Private Placement Warrants and Working Capital Warrants were $ 2.9 million, $ 7.4 million, and $ 1.7 million, respectively. As of December 31, 2024, the fair values of the Public Warrants, Private Placement Warrants and Working Capital Warrants were $ 1.9 million, $ 4.9 million, and $ 1.1 million, respectively. The fair value of the Public Warrants has been measured based on the quoted price of such warrants on the Nasdaq. The transfer of Private Placement Warrants or Working Capital Warrants to anyone outside of a small group of individuals who are permitted transferees would result in the Private Placement Warrants and Working Capital Warrants having substantially the same terms as the Public Warrants. Therefore, we determined that the fair value of each Private Warrant and Working Capital Warrants is equivalent to that of each Public Warrant. On May 24, 2024, we commenced (i) the Offer and (ii) the solicitation of consent (the “Consent Solicitation”) from holders of the Exchange Warrants to amend the Warrant Agreement, dated as of December 17, 2020 (the “Warrant Agreement” and such amendment, the “Warrant Amendment”), by and between the Company and Continental Stock Transfer & Trust Company, which governs all of the Exchange Warrants. The Offer and Consent Solicitation expired at one minute after 11:59 p.m., Eastern Standard Time, on June 25, 2024. The Exchange Warrants tendered were comprised of 6,529,954 Public Warrants and 504,685 Private Placement Warrants, which represents approximately 78.8 % and 10.2 % of the outstanding warrants of each respective class. The Warrants were validly tendered and not validly withdrawn prior to the expiration of the Offer and Consent Solicitation. No Working Capital Warrants were tendered. We determined the Exchange Warrants met the criteria to be equity classified at June 26, 2024, and that their fair value was $ 11.9 million. Accordingly, we recorded that amount as a reduction of the warrant and SEPA liabilities and an increase to additional paid-in capital on the consolidated balance sheets, partially offset by issuance costs of $ 1.7 million. On July 1, 2024, we issued 2,110,366 shares of common stock in exchange for the Exchange Warrants. In addition, the Warrant Amendment was entered into with respect to the Public Warrants. As a result all of the outstanding Public Warrants may be exchanged, at our option, at any time while they are exercisable and prior to their expiration, at the office of the warrant agent, upon notice to the holders of the then outstanding Public Warrants, at the exchange rate of 0.27 shares of Common Stock per Public Warrant (subject to equitable adjustment by us in the event of any stock splits, stock dividends, recapitalizations or similar transaction with respect to the Common Stock). For the year ended December 31, 2024, we issued 2,110,366 shares of common stock in exchange for 6,529,954 (or approximately 78.8 %) of the Public Warrants and 504,685 (or approximately 10.2 %) of the Private Placement Warrants. The following tables summarizes activity in the Public Warrants, Private Placement Warrants and Working Capital Warrants for the years ended December 31, 2025 and 2024.

As of December 31, 2025, the exercise price was $ 8.8398 per share pursuant to the terms of the Initial OrbiMed Warrant, or approximately $ 1.2 million in the aggregate. The Initial OrbiMed Warrant expires on April 30, 2031 (the "Expiration Date"). On each of the closings of the Delayed Draw Commitment Amounts (see Note 12), if any, we agreed to issue additional warrants to purchase a number of shares of our common stock determined by dividing 5.0 % of the applicable borrowed amount by the 10-day volume weighted average sale price of our common stock as of the issue date (the “Subsequent OrbiMed Warrants” and collectively, with the Initial OrbiMed Warrant, the “OrbiMed Warrants” and together with the SPAC Warrants, the “Warrants”). The Subsequent Warrants will expire seven years from each applicable issuance date, if any. In connection with the OrbiMed Warrants, we entered into a Registration Rights Agreement with OrbiMed (the “OrbiMed Registration Rights Agreement”), whereby OrbiMed will have certain customary registration rights with respect to the shares of common stock underlying the OrbiMed Warrants. In connection with the First Delayed Draw Term Loan Commitment draw (see Note 12) on February 18, 2025, we issued the OrbiMed operating entities a warrant to purchase 64,748 and 26,515 shares of our common stock (the "Subsequent OrbiMed Warrants"), with the initial exercise price of $ 5.4787 , or approximately $ 0.5 million. As of December 31, 2025, the Exercise Price was $ 5.3322 per share pursuant to the terms of the Subsequent OrbiMed Warrant, or approximately $ 0.5 million in the aggregate. The Subsequent OrbiMed Warrant expires on February 18, 2032 (the "Expiration Date"). The OrbiMed Warrant may be exercised in whole or in part, at any time prior to the Expiration Date (the "Exercise Period"), by either: a. making a payment to the Company, in an amount in immediately available funds equal to the aggregate Exercise Price to be paid upon the exercise of the OrbiMed Warrant; or b. instructing the Company to withhold a number of Warrant Shares then issuable upon exercise of the OrbiMed Warrant with an aggregate fair market value as of the exercise date equal to such aggregate Exercise Price to be paid upon the exercise of the OrbiMed Warrant (the “Cashless Exercise”). If either upon (i) the occurrence of the Expiration Date, or (ii) the date on which a Sale of the Company is consummated pursuant to which the sole consideration payable to the Company or its stockholders in respect of such sale transaction consists of cash, marketable securities or a combination thereof, and the per share fair market value of a Warrant Share is greater than the exercise price, any portion of the OrbiMed Warrant that remains unexercised on such date shall be deemed to have been exercised automatically pursuant to a Cashless Exercise (the “Automatic Cashless Exercise”). Ownership Cap The holder in any circumstance cannot exercise the OrbiMed Warrant if such exercise would result in the holder and its affiliates to own more than 9.99 % of the Company's common stock (the “Ownership Cap”). Adjustments The current Exercise Price and the number of Warrant Shares underlying the OrbiMed Warrants are subject to certain anti-dilutive adjustments. These are triggered by events such as stock splits, reclassification of shares, combinations or substitutions. Additionally, the Exercise Price will be adjusted if shares,which include options and convertible securities settled in common stock) are issued at a price per share less than the current Exercise Price. These adjustments are collectively referred to as "Warrant Adjustments.” If we declare or pay a dividend or distribution on our outstanding common shares payable in cash, capital securities or other property, the OrbiMed Warrant Holder shall be entitled to receive, at the time such dividend or distribution is paid, without additional cost to the OrbiMed Warrant Holder, the total number and kind of cash, capital securities or other property which the OrbiMed Warrant Holder would have received had the OrbiMed Warrant Holder owned the Warrant Shares of record as of the date such dividend or distribution was paid (the “Pro-Rata Distribution”). Additionally, the OrbiMed Warrants are subject to customary price-based anti-dilution protections, such that, in certain circumstances, if we issue shares of our common stock below the current exercise price of the Initial OrbiMed Warrant, the exercise price of the OrbiMed Warrants will be adjusted downward based on such issuance. As a result of any adjustments, the amount of proceeds we receive from the exercise of the OrbiMed Warrants would be less than the amount we would receive immediately prior to such adjustment. 103 Table of Contents Transfers of OrbiMed Warrant The OrbiMed Warrant may be transferred or assigned in whole or in part, subject to compliance with applicable federal and state securities laws. Allocation of Proceeds and Issuance Costs The agreement explicitly permits the settlement of the OrbiMed Warrants in a cashless manner (i.e., net share settlement) and not indexed to the Company's own stock. Therefore, it is considered as a derivative instrument under ASC 815 and will be classified as a liability and is subsequently measured at fair value with changes reported within the change in fair value of SEPA, warrant and revenue base redemption liabilities of the consolidated statement of operations following the proceeds from the issuance of the Initial Term Loan. Fair Value The estimated fair value of the OrbiMed Warrant liabilities were determined using a Monte Carlo simulation valuation model using a distribution of potential outcomes. The inputs and assumptions utilized in the calculation require management to apply judgment and make estimates including: (a) expected term, based on the Initial Term Loan maturity date; (b) risk-free interest rate, which was determined by reference to the U.S. Treasury yield curve for time periods commensurate with the expected term; (c) expected volatility, which is based on the historical equity volatility of publicly traded peer companies for a term equal to the expected term; (d) expected dividend yield, which we estimate to be 0 % based on the fact that we have never paid or declared dividends on the Company's common stock; (e) exercise price, which we calculate as prescribed by the OrbiMed Credit Agreement; and (f) our stock price, as of the closing price per the Nasdaq on the last day of the reporting period. The fair value of the Initial OrbiMed Warrant was measured using the Black-Scholes option pricing model. The key inputs used in the valuations were as follows: December 31, 2025 December 31, 2024 Expected term (years) 5.3 6.3 Risk free interest rate 3.8 % 4.5 % Expected volatility 70.0 % 70.0 % Dividend yield — % — % Exercise price $ 8.8398 $ 9.3722 Stock price $ 6.98 $ 5.01 The fair value of the Subsequent OrbiMed Warrant was measured using the Black-Scholes option pricing model. The key inputs used in the valuations were as follows: December 31, 2025 February 18, 2025 Expected term (years) 6.1 7.0 Risk free interest rate 3.9 % 4.1 % Expected volatility 70.0 % 70.0 % Dividend yield — % — % Exercise price $ 5.3322 $ 5.4787 Stock price $ 6.98 $ 5.69 These estimates may be subjective in nature and involve uncertainties and matters of judgment and therefore cannot be determined with exact precision. 104 Table of Contents (9) Income Taxes We utilize the balance sheet method of accounting for income taxes and deferred taxes which are determined based on the differences between the financial statements and tax basis of assets and liabilities given the provisions of the enacted tax laws. The income tax expenses (benefits) from continuing operations are summarized as follows: December 31, 2025 December 31, 2024 Federal: Current $ ( 9 ) $ ( 15 ) Deferred — — ( 9 ) ( 15 ) State: Current 16 21 Deferred — — 16 21 Income tax expense $ 7 $ 6 We adopted ASU 2023-09 Income Taxes (Topic 740): Improvements To Income Tax Disclosures on a prospective basis beginning with the year ended December 31, 2025. The following table presents required disclosure pursuant to ASU 2023-09 and reconciles the U.S. federal statutory income tax amount and rate to our actual effective amount and rate for the year ended December 31, 2025: December 31, 2025 Amount Percent Statutory rate $ ( 8,256 ) 21.0 % State and local taxes (1) ( 1,252 ) 3.2 Change in valuation allowance 7,446 ( 18.9 ) Other adjustments 248 ( 0.6 ) Permanent differences - change in fair value of contingent earnout liability 576 ( 1.5 ) Permanent differences - change in fair value of SEPA, warrant and revenue base redemption liabilities 858 ( 2.2 ) Permanent differences - other 387 ( 1.0 ) $ 7 — % _______________________ (1) Tax jurisdictions that comprise more than 50% of state and local income tax expense for the year ended December 31, 2025 consisted of the following (in order of magnitude): California, New York, New Jersey, Pennsylvania, Massachusetts and Louisiana. The following table presents the required disclosures prior to our adoption of ASU 2023-09 and reconciles the U.S. federal statutory income tax rate to our actual effective income tax rate for the year ended December 31, 2024: December 31, 2024 Statutory rate 21.0 % State and local taxes 5.1 Change in valuation allowance ( 33.1 ) Other adjustments 1.7 Permanent differences 5.3 — % 105 Table of Contents The income tax effects of temporary differences that give rise to significant portions of the deferred income tax assets and liabilities as of December 31, 2025 and 2024 are presented below: December 31, 2025 December 31, 2024 Deferred tax assets: NOL carryforwards $ 53,962 $ 44,336 Fixed assets 2,941 2,664 Accrued liabilities 562 140 Inventory 529 652 Interest limitation — 674 Charitable contributions 26 33 Lease accounting 114 52 Capitalized R&D expenses 8,209 11,919 Stock-based compensation expense 2,731 1,264 Total deferred income tax assets 69,074 61,734 Deferred tax liabilities: Prepaid expenses ( 342 ) ( 407 ) Total deferred income tax assets and liabilities 68,732 61,327 Less: Valuation allowance ( 68,732 ) ( 61,327 ) Net deferred income tax assets and liabilities $ — $ — In assessing the realizability of our deferred tax assets, we consider whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. We consider the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in making this assessment. As we do not have any historical taxable income, projections of future taxable income over the periods in which the deferred tax assets are deductible and after consideration of the history of operating losses, we do not believe it is more likely than not that we will realize the benefits of the net deferred tax assets and accordingly, have established a valuation allowance equal to 100 % of net deferred tax assets. The change in the valuation allowance for the years ended December 31, 2025 and 2024 was $ 7.4 million and $ 10.0 million, respectively. As of December 31, 2025, we had net operating losses (“NOLs”) as follows (the NOLs which do not expire are subject to an annual utilization limitation of 80% of taxable income): December 31, 2025 Federal State NOLs expiring between 2029 and 2037 $ 43,912 $ 128,004 NOLs which do not expire 174,705 45,433 Total NOLs $ 218,617 $ 173,437 The Internal Revenue Code contains provisions that may further limit the net operating loss carryovers available to be used in any one year if certain events occur, including significant changes in ownership interests. Utilization of net operating loss and tax credit carryforwards are subject to a substantial annual limitation due to the ownership change limitations set forth in Section 382 of the Code and similar state provisions. We prepared an Internal Revenue Code 382 analysis to determine the annual limitations on our consolidated net operating loss carryforwards. All of our tax attributes are subject to an annual limitation. Such annual limitations could result in the expiration of the net operating loss and tax credit carryforwards before utilization. As of December 31, 2025 and 2024, we did not have any unrecognized tax benefits and do not expect that the amount of unrecognized tax benefits will change significantly within the next 12 months. Our accounting policy is to accrue interest and penalties related to unrecognized tax benefits as a component of income tax expense. 106 Table of Contents We are subject to taxation in the United States, various state jurisdictions, and various foreign jurisdictions. We are subject to income tax examination by U.S. and state tax authorities for the calendar year ended December 31, 2025 and forward. However, to the extent allowed by law, the taxing authorities may have the right to examine prior periods where net operating losses and credits were generated and carried forward, and make adjustments up to the amount of the net operating losses and credits utilized in open tax years. (10) Dynavax Purchase We purchased all of the intellectual property and trial drug substance for nelitolimod from Dynavax Technologies (“Dynavax”) in 2020. This was a purchase of in-process research and development. Nelitolimod, an investigational agent in development, is a TLR9 agonist which is believed to bind to the TLR9 receptors found on suppressive immune cells including myeloid-derived suppressor cells and antigen-presenting immune cells. We believe that nelitolimod, when delivered using our PEDD devices, can improve therapeutic distribution to solid tumors and improve outcomes for liver metastases and Locally Advanced Pancreatic Ductal Adenocarcinoma ("LA-PDAC"). Payments under the Dynavax purchase agreement consist of: (a) one upfront payment of $ 9.0 million, (b) milestone payments upon the achievement of certain development and commercial milestones, and (c) royalty payments based on aggregate annual net sales after nelitolimod receives Food and Drug Administration ("FDA") approval to be sold. The development milestone payments range from $ 1.0 million to $ 10.0 million, triggered by development achievements for each of up to four indications. The development milestone payments cannot exceed $ 170.0 million. We made a milestone payment of $ 1.0 million in September 2021, after initiating our clinical study of uveal melanoma liver metastases, $ 1.0 million in June 2022, after initiating our clinical study for primary liver tumors, and $ 1.0 million in August 2023, after initiating our clinical study for LA-PDAC. In aggregate, the commercial milestones shall not exceed $ 80.0 million. We will also pay annual royalties at the rate of 10 % for aggregate annual net sales less than or equal to $ 1.0 billion and 12 % for aggregate annual net sales above that amount. We record the milestone payments in R&D expense when they are incurred. The milestone payments and royalty payments are contingent upon future events and therefore will also be recorded as expense when it is probable that a milestone has been achieved or when royalties are due. During the years ended December 31, 2025 and 2024, we made no payments to Dynavax. (11) Standby Equity Purchase Agreement In October 2023, we entered into a SEPA with Yorkville Advisors Global, LP ("Yorkville"). Pursuant to the SEPA, the Company had the right, but not the obligation, to sell to Yorkville up to $ 30.0 million of Common Stock, par value $ 0.0001 per share, at our request any time during the commitment period commencing on October 2, 2023 (the “Effective Date”) and terminating on the first day of the month following the 24 -month anniversary of the Effective Date (the "Commitment Period"), which was November 1, 2025. Each issuance and sale to Yorkville under the SEPA (an “Advance”) was subject to a maximum limit equal to the greater of: (i) an amount equal to 100 % of the average of the daily volume of the Common Stock on the Nasdaq for the 10 trading days immediately preceding an Advance notice, or (ii) 1,000,000 shares of Common Stock. During the Commitment Period, the Company had the option to issue and sell shares to Yorkville at a per-share price equal to: (i) 96 % of the Market Price (as defined below) for any period commencing on the receipt of the Advance notice by Yorkville and ending on 4:00 p.m. New York City time on the applicable Advance notice date (the “Option 1 Pricing Period”), or (ii) 97 % of the Market Price for any three consecutive trading days commencing on the Advance notice date (the “Option 2 Pricing Period,” and each of the Option 1 Pricing Period and the Option 2 Pricing Period, a “Pricing Period”). “Market Price” is defined as, for any Option 1 Pricing Period, the daily volume-weighted average price (“VWAP”) of the Common Stock on Nasdaq, and for any Option 2 Pricing Period, the lowest VWAP of the Common Stock on the Nasdaq during the Option 2 Pricing Period. The Advances were subject to certain limitations, including that Yorkville could not purchase any shares that would result in it beneficially owning more than 4.99 % of the outstanding voting power or Common Stock. Further, Yorkville could not purchase shares that would result in it acquiring more than 5,260,704 shares of Common Stock, which represented 19.99 % of the outstanding Common Stock, as of the effective date of SEPA. As described in Note 2, the SEPA contract was accounted for as a derivative as it was an equity-linked contract that did not qualify for equity classification under ASC 815. Therefore, the SEPA was recognized as a liability measured each period at fair value in accordance with ASC 820, Fair Value Measurement, on the consolidated balance sheets and the change in fair value of the SEPA liability is recorded on the consolidated statements of operations. We did not issue any Advances during the year ended December 31, 2025. 107 Table of Contents The estimated fair value of the SEPA derivative liability on December 31, 2024 was $ 0.1 million, which was determined using a scenario-based valuation model. During the year ended December 31, 2025, the liability was remeasured to its fair value of zero as of September 30, 2025, due to not having any intentions to utilize the SEPA prior to its expiration on November 1, 2025. This remeasurement resulted in the recognition of an immaterial gain of $ 0.1 million for the year ended December 31, 2025, which is included in change in fair value of warrant, SEPA and revenue base redemption liabilities in the consolidated statement of operations. As the SEPA expired on November 1, 2025, no valuation was performed as of December 31, 2025. Assumptions used in the valuation as of December 31, 2024 are described below: Valuation assumptions: December 31, 2024 Expected draws $ 2,000 Expected probability of draws 90.0 % Risk-free interest rate 4.4 % The estimated fair value of the liability was determined using a scenario-based valuation model which assigned a probability to a number of different outcomes. The inputs and assumptions utilized in the calculation require management to apply judgment and make estimates including: (a) total expected draws of $ 2.0 million through the issuance of multiple separate advances under the Option 2 Pricing Period as of December 31, 2024; (b) the expected probability of the draws on the SEPA, which we estimate based on our expectation of the draws being completed; and (c) risk-free interest rate, which was determined by reference to the U.S. Treasury yield curve for time periods commensurate with the expected term of the agreement in relation to the date of the expected draw. These estimates may be subjective in nature and involve uncertainties and matters of judgment and therefore cannot be determined with exact precision. As of December 31, 2024, we had sold 2,290,377 shares of common stock under the SEPA, raising approximately $ 14.1 million. (12) Debt On April 30, 2024 (the "OrbiMed Closing Date"), we entered into the Credit Agreement with OrbiMed, a healthcare investment firm, and certain of its affiliates to support the execution of strategic expansion plans, fuel continued growth and provide financial flexibility. Pursuant to the to the OrbiMed Credit Agreement, OrbiMed agreed to provide a term loan facility to the borrower, in an aggregate principal amount of $ 50.0 million, as follows: a. $ 25.0 million funded on the OrbiMed Closing Date (the “Initial Term Loan”). b. $ 10.0 million term loan available at the election of the Company, provided that Product Revenue Base for the trailing 12-months ending on the last day of the month immediately prior to the funding of such loan was at least $ 30.0 million (the “First Delayed Draw Term Loan Commitment”). The First Delayed Draw Term Loan Commitment expired on June 30, 2025. c. An additional $ 15.0 million term loan available at the election of the Company, provided that Product Revenue Base for the trailing 12-months ending on the last day of the month immediately prior to the funding of such loan was at least $ 50.0 million (the “Second Delayed Draw Term Loan Commitment” and together with the First Delayed Draw Term Loan Commitment, the “DDTL Commitments”). The Second Delayed Draw Term Loan Commitment expired on December 31, 2025. On April 30, 2024, we borrowed the Initial Term Loan, resulting in gross proceeds of $ 25.0 million. On February 18, 2025, we borrowed the First Delayed Draw Term Loan Commitment resulting in gross proceeds of $ 10.0 million based on achieving the trailing 12-month Product Revenue Base of $ 30.0 million in January 2025. The Initial Term Loan and the First Delayed Draw Term Loan (collectively, the "Term Loan") mature on April 30, 2029 (the "Maturity Date"). 108 Table of Contents The OrbiMed Credit Agreement includes a subjective acceleration clause whereby an event of default, including a material adverse change in the business, operations or conditions, could result in the acceleration of the obligations under the OrbiMed Credit Agreement. Under certain circumstances, a default interest rate of an additional 4.0 % per annum will apply, at the election of OrbiMed, on all outstanding obligations during the occurrence and continuance of an event of default. OrbiMed can also declare all or a portion of the outstanding principal amount of the loan due and payable, and cancel any unmade draws. OrbiMed has not exercised its right under this clause as there have been no such events. As part of the First Amendment to the OrbiMed Credit Agreement and Registration Rights Agreement, effective March 20, 2025, we received a waiver for the prior default events related to the Series A Convertible Preferred Stock conversions and the OrbiMed Credit Agreement was amended to allow for these conversions going forward. In addition, we received a waiver on March 31, 2025 to extend the timing for the required audited financial statements to occur on or before April 15, 2025. Effective on April 30, 2025, the Second Amendment to the OrbiMed Credit Agreement allows for the Company to accelerate payment of the Series A Preferred Stock dividends in cash payments in lieu of fractional shares upon conversion of Preferred Stock. On November 10, 2025, we entered into the Third Amendment to the OrbiMed Credit Agreement ("OrbiMed Third Amendment"), which lowered the minimum cash requirement for the liquidity covenant from $ 10.0 million to $ 5.0 million. In addition, we received a waiver for the prior default related to the 30 days written notice of the change in our Chief Financial Officer. Repayment If the Product Revenue Base (i.e., with respect to any period, the net revenues for such period from sales of TriNav) on a trailing 12-month basis does not equal or exceed the specified amount as stipulated in table below, the Company will start repaying the outstanding principal amount on the Term Loans. Such repayments will commence in the calendar month immediately following the applicable Test Date (stipulated in the table below) and occur on the last day of each calendar month ("Amortization Payment Date"). The repayments are made in equal monthly installments, calculated from the first Amortization Payment Date through the Maturity Date and the balance of the principal amount of the loans under the OrbiMed Credit Agreement shall be repaid on the Maturity Date. The repayments include the applicable Repayment Premium and the Exit Fee (each as defined below). The repayment of the of the loans under the OrbiMed Credit Agreement as aforementioned, is referred to as the “revenue base redemption liability.” Test Dates (fiscal Quarter Ending) Product Revenue Base for 12 months Period December 31, 2025 $ 42,700 March 31, 2026 $ 46,400 June 30, 2026 and each Fiscal Quarter ending thereafter $ 50,000 As of December 31, 2025, we were in compliance with the Product Revenue Base requirement and no repayments were required. 109 Table of Contents Repayment Premium All repayments and prepayments of the loans under the OrbiMed Credit Agreement (other than on Maturity Date) shall be accompanied by the payment of the premium, which shall be determined based on the timing of the repayment as follows (the “Repayment Premium”): Time of Repayment Premium Rate Within the first 12 months from the funding date of each respective loan. 3.0 % plus the Make-Whole Amount (1) After the first 12 months but before the 24-month anniversary of the funding date of each respective loan. 3.0 % After the 24-month anniversary but before the 36-month anniversary of the funding date of each respective loan. 2.0 % After the 36-month anniversary but before the 48-month anniversary of the funding date of each respective loan. 1.0 % After the 48-month anniversary of the funding date of each respective loan. 0.0 % (1) “Make-Whole Amount” is equal to the sum of the remaining scheduled interest payments through the 12-month anniversary of the closing date of each respective loa n. Interest Rate and Payment The interest rate is calculated as Secured Overnight Financing Rate for the interest period (which shall not be less than 4.0 % (the “Floor”)) plus 8.5 % (the “Interest Rate”). Until the first full interest period after the 15 month anniversary of the OrbiMed Closing Date, 3.5 % of the Interest Rate shall be designated as paid-in-kind interest, which is added to the outstanding principal amount of the loans under the OrbiMed Credit Agreement (the “PIK Interest”). However, the borrower upon written notice can elect to pay all interest in cash, or to pay a percentage less than 3.5 % as PIK Interest. On and after occurrence of any event of default, until such event of default is cured, the borrower is obligated to pay 4.0 % in addition to the otherwise applicable Interest Rate (the “Default Rate”). Interest payments (except PIK Interest) are due on the last day of the month. Whenever a prepayment is made on the principal of the Term Loans, the accrued interest and any applicable Repayment Premium on the amount prepaid is also due on such date. Warrant In connection with the closing of the OrbiMed Credit Agreement, we issued OrbiMed the Initial OrbiMed Warrant. Subsequent to achieving the First Delayed Draw Term Loan Commitment revenue requirement, the Subsequent OrbiMed Warrant was issued (see Note 8) for further discussion. Debt Related Fees Exit Fee The borrower on the repayment of the loans under the OrbiMed Credit Agreement is obligated to pay an additional fee equal to 4.0 % of the of the principal amount being repaid. This applies whether the repayment is made on the Maturity Date, or under any other conditions specified in the Agreement (the “Exit Fee”). The Exit Fee is amortized over the term of the Term Loans. Commitment Fee The borrower on the funding date of the loans under the OrbiMed Credit Agreement, shall pay a commitment fee to the Lender, equal to 2.0 % of the principal amount drawn (the “Commitment Fee”). The Commitment Fee was recorded as a debt discount and amortized over the life of the Term Loans. Undrawn Fee Every month, the borrower is obligated to remit a fee to the lender, calculated as 0.25 % per annum of the total undrawn amount under the DDTL Commitments. The Undrawn Fee is accounted for as a service fee, which is expensed as incurred. 110 Table of Contents Administrative Fee The borrower will pay to the agent under the OrbiMed Credit Agreement for its own account a quarterly loan administration fee of $ 0.01 million, payable in advance, with the first payment due and payable upon the OrbiMed Closing Date. In 2024, we recorded the Initial Term Loan and the First Delay Draw as Long-term debt, and recorded the issuance costs incurred to obtain the loan as contra-debt, in accordance with ASC 470, Debt . We incurred $ 2.6 million in legal, origination and other fees to acquire the OrbiMed Credit Agreement. During the year ended December 31, 2025, we recorded interest expense of $ 5.5 million related to borrowings under the OrbiMed Credit Agreement on the consolidated statements of operations, of which $ 0.8 million was recorded as PIK Interest, $ 3.7 million was cash interest, and $ 1.0 million was amortization of debt issuance costs and debt discount. The following table summarizes activity within the Term Loan for the years ended December 31, 2025 and December 31, 2024: OrbiMed Debt Initial draw $ 25,000 Debt issuance costs Cash issuance costs ( 2,593 ) Noncash issuance costs: Revenue base redemption liability ( 729 ) Warrant liability ( 811 ) Balance at April 30, 2024 $ 20,867 Amortization of debt issuance costs 486 PIK interest 604 Accretion of exit fee liability 127 Balance at December 31, 2024 $ 22,084 First Delayed Draw Term Loan Commitment 10,000 Debt issuance costs Cash issuance costs ( 521 ) Noncash issuance costs: Warrant liability ( 366 ) Amortization of debt issuance costs 766 PIK interest 800 Accretion of exit fee liability 283 Balance at December 31, 2025 $ 33,046 (13) Convertible Preferred Stock As of December 31, 2024, the Company had 3,985,002 shares of Series A Convertible Preferred Stock ("Preferred Stock") outstanding. The original issue price of the Series A Convertible Preferred Stock was $ 10.00 . The Series A Convertible Preferred Stock accrued cumulative dividends at the rate of 8.00 % per annum on the original issue price. As of December 31, 2024, total undeclared cumulative dividends were $ 4.4 million, which were not recorded in our consolidated financial statements, except actual undeclared dividends of $ 3.2 million as a reconciling item for net loss attributable to common stockholders on the consolidated statements of operations. On June 23, 2025, the Company commenced an offer (the “Offer”) to all holders of Preferred Stock to exchange their shares of Preferred Stock for Common Stock equal to the sum of the liquidation preference per share price of $ 10.00 and all accrued and unpaid dividends per share outstanding through August 10, 2027, divided by a $ 4.00 conversion price per share. The Offer expired at one minute after 11:59 p.m., Eastern Daylight Time, on July 23, 2025. For any Preferred Stock holders that did not participate in the Offer, the Company had the right to call their Preferred Stock shares for conversion into Common Stock shares equal to the sum of the liquidation preference per share price of $ 10.00 and all accrued and unpaid dividends per share outstanding through the conversion date, divided by a $ 5.227 conversion price per share. 111 Table of Contents Approximately 98.8 % of the outstanding shares of Preferred Stock shares were tendered through the Offer and were accepted for exchange, resulting in 3,551,502 shares of Preferred Stock converted to 11,719,956 shares of Common Stock. For the holders of Preferred Stock that did not participate in the Offer, the Company called their Preferred Stock and 42,500 shares of Preferred Stock were converted to 93,103 shares of Common Stock. All shares of Preferred Stock were converted for common stock shares on July 31, 2025, resulting in the issuance of 11,813,059 Common Stock shares. As of December 31, 2025 and subsequent to the Preferred Stock Conversion, there are no outstanding shares of Preferred Stock. The Company is authorized to issue up to 10,000,000 shares of preferred stock with 10,000,000 shares available for issuance. (14) Stock-Based Compensation Equity Incentive Plans We currently maintain the 2023 Equity Incentive Plan (the “2023 Plan”), which our Board of Directors (the "Board") and stockholders approved in connection with the Business Combination, for purposes of granting equity-based incentive awards to our employees, executive officers, directors and consultants. Prior to the Business Combination, TriSalus granted equity incentive awards under the 2009 Amended and Restated Equity Incentive Plan (the “2009 Plan”). The 2009 Plan has not been used following the Business Combination. However, any awards granted under the 2009 Plan remain subject to the terms of the 2009 Plan and the applicable award agreement. Initially, 5,585,008 shares were authorized under the 2023 Plan. In addition, the share reserve will automatically increase on January 1 of each year for a period of ten years , commencing on January 1, 2024, and ending on January 1, 2033, in an amount equal to (1) five percent of the total number of shares of the fully diluted common stock determined on December 31 of the preceding year, or (2) a lesser number of shares of Common Stock determined by our Board prior to January 1 of a given year. The 2023 Plan will expire on August 10, 2033, unless modified by the Board of Directors or a duty authorized committee thereof. Our Board may also delegate to one or more of our officers the authority to, among other things, (1) designate employees (other than officers) to receive specified stock awards and (2) determine the number of shares subject to such stock awards. Under the 2023 Plan, the Board has the authority to determine award recipients, grant dates, the numbers and types of stock awards to be granted, the applicable fair market value and exercise price, and the provisions of each stock award, including the exercise period and the vesting schedule applicable to a stock award, subject to the limitations of the 2023 Plan. The Board delegated the authority to administer the 2009 Plan and the 2023 Plan our CEO and CFO, who act on the recommendation of managers of the Company to select the individuals to whom the awards will be granted and to determine the amount and vesting period for the grants. All grants are subject to approval by the Board. As of December 31, 2025, the balances under the two plans are below. December 31, 2025 Authorized Outstanding (1) Available for Issue 2009 Plan 1,992,689 1,165,317 — 2023 Plan 10,354,247 8,067,960 1,901,532 Total 12,346,936 9,233,277 1,901,532 (1) Outstanding excludes RSU releases and option exercises for the 2009 and 2023 Plans as well as RSU forfeitures for the 2009 Plan as they were not returned to the plan. 112 Table of Contents Stock Options Historically, we have used stock options as an incentive for long-term compensation to our executive officers because options allow our executive officers to realize value from this form of equity compensation only if the value of the underlying equity securities increase relative to the option’s exercise price. Stock options are granted with an exercise price equal to the fair market value of our common stock on the grant date. Stock options generally have a ten-year contractual term and typically have graded vesting over one to four years . We may grant stock options with a performance condition. The performance stock options vest upon meeting the stated performance metric(s) during the stated performance period(s). We assess the probability of the performance stock options meeting the performance metric(s), and if probable, we recognize compensation expense over the requisite service period. We granted one performance stock option award in 2025. The following table summarizes activity for stock options under the 2009 Plan and 2023 Plan for the year ended December 31, 2025 : Number of Stock Options Weighted-Average Exercise Price Weighted-Average Remaining Contractual Life (in years) Aggregate Intrinsic Value (in thousands) Outstanding at January 1, 2025 4,591,539 $ 6.46 6.2 $ 3,864 Granted 3,821,338 5.23 Exercised ( 144,150 ) 3.43 $ 260 Forfeited ( 759,570 ) 5.54 Expired ( 102,493 ) 8.87 Outstanding at December 31, 2025 7,406,664 $ 5.94 7.4 $ 13,358 Exercisable at December 31, 2025 2,942,814 $ 6.02 5.1 $ 6,511 The aggregate intrinsic value of options exercised during the year ended December 31, 2024 was $ 0.4 million. The related cash received, net of tax, was approximately $ 0.5 million for the year ended December 31, 2025. The fair value of each stock option granted during the years ended December 31, 2025 and 2024 was determined using the Black-Scholes option pricing model. The following table summarizes the weighted-average grant date fair value and assumptions used to develop the fair value estimates for the options granted during the years ended December 31, 2025 and 2024, respectively: December 31, 2025 December 31, 2024 Weighted-average grant date fair value $ 2.90 $ 4.55 Expected volatility 53.5 % 54.2 % Risk-free interest rate 4.0 % 4.1 % Expected term (years) (1) 6.2 6.2 Expected dividend yield — % — % _______________________ (1) Our historical exercise behavior for previous grants does not provide a reasonable estimate for future exercise activity. Therefore, the expected term was calculated using the simplified method, which is the average of the option's vesting and contractual term. We recorded compensation expense for stock options during the years ended December 31, 2025 and 2024 was $ 6.3 million and $ 3.9 million, respectively. As of December 31, 2025, there was $ 13.2 million of unrecognized compensation expense related to stock options and will be expensed over a weighted average period of 2.9 years. 113 Table of Contents Restricted and Performance Stock Pursuant to both the 2009 and 2023 Plans, we issue restricted stock unit awards ("RSUs") and performance stock unit awards ("PSUs"). The estimated fair value of the awards at the time of grant was determined using the price of our common stock on the grant date for the RSUs and PSUs. All such grants are satisfied through the issuance of new shares. RSUs are share awards that, upon vesting, will deliver to the holder shares of our common stock at specified vesting dates. Typically, RSUs vest over four years , with 25 % of the awarded units vesting at each annual anniversary of the grant date. PSUs are share awards that vest upon meeting the stated performance metric(s) during the stated performance period(s). We assess the probability of PSUs meeting the performance metric(s), and if probable, we recognize compensation expense over the requisite service period. We granted one PSU award in 2025 and 2024, respectively. The following table summarize activity for RSUs and PSUs under the 2009 Plan and 2023 Plan for the year ended December 31, 2025: Number of Stock Units Weighted-Average Grant-Date Fair Value per Share Unvested at January 1, 2025 459,357 $ 9.51 Granted 1,764,736 5.46 Vested ( 324,626 ) 6.92 Forfeited ( 72,854 ) 6.39 Unvested at December 31, 2025 1,826,613 $ 6.18 The weighted-average grant date fair value of RSUs and PSUs granted during the year ended December 31, 2024 was $ 9.46 . The fair value of RSUs and PSUs vested during the years ended December 31, 2025 and 2024 was $ 1.7 million and $ 0.1 million, respectively. We recorded compensation expense for RSUs and PSUs during the years ended December 31, 2025 and 2024 was $ 2.7 million and $ 1.3 million. As of December 31, 2025, there was $ 9.1 million of unrecognized compensation expense related to RSUs and PSUs and will be expensed over a weighted-average period of 3.0 years. Employee Stock Purchase Plan We maintain an Employee Stock Purchase Plan ("ESPP"), which provides our eligible employees and certain designated companies with an opportunity to purchase shares of Common Stock, to assist us in retaining the services of eligible employees, to secure and retain the services of new employees, and to provide incentives for such persons to exert maximum efforts for our success. The ESPP became active in 2024. There were 2,350,530 shares of Common Stock initially reserved for issuance under the ESPP. The number of shares of Common Stock reserved for issuance under the ESPP will automatically increase on January 1 of each year for a period of up to ten years , beginning on January 1, 2024, and continuing through and including January 1, 2033, by an amount equal to the lesser of (a) two percent ( 2 %) of the total number of shares of the fully diluted common stock determined on December 31 of the preceding year, and (b) 200 % of the Initial Share Reserve. On January 1, 2025, the authorized shares under ESPP increased by 953,418 shares to 3,303,948 . During the year ended December 31, 2025, 94,066 shares were purchased in an offering under the ESPP, for which we recognized compensation expense of $ 0.1 million. We record the issuance of shares when they are recorded by the transfer agent and, as such, there could be timing differences between when the expense is recorded and shares are transferred. 114 Table of Contents (15) Net Loss Per Share Basic net loss per share is computed by dividing the net loss attributable to common stockholders by the weighted-average number of common shares outstanding for the period. During periods where we might earn net income, we would allocate to participating securities a proportional share of net income determined by dividing total weighted-average participating securities by the sum of the total weighted-average common shares and participating securities (the “two-class method”). Our preferred stock, if any, participates in any dividends declared by us and are therefore considered to be participating securities. Participating securities have the effect of diluting both basic and diluted earnings per share during periods of income. During periods where we incurred net losses, we allocate no loss to participating securities because they have no contractual obligation to share in our losses. We computed diluted loss per common share after giving consideration to the dilutive effect of stock options, RSUs, PSUs and warrants that are outstanding during the period, except where such nonparticipating securities would be antidilutive. As we have reported net losses for the years ended December 31, 2025 and 2024, diluted net loss per common share is the same as basic net loss per common share for those periods. The following potentially dilutive securities (in common stock equivalent shares) have been excluded from the computation of diluted weighted-average shares outstanding because such securities have an antidilutive impact due to losses reported: December 31, 2025 2024 Preferred stock — 25,048,584 Common stock warrants 7,402,541 7,311,278 RSUs and PSUs 1,826,613 459,357 Stock options 7,406,664 4,591,539 Shares issuable under the SEPA — 3,468,998 Total 16,635,818 40,879,756 (16) Leases We have two property leases in effect as of December 31, 2025, which we account for as operating leases. We lease office, manufacturing and warehouse space under these leases. Both leases contain options to extend the respective lease terms, which were excluded in determining the expected lease term as it was not reasonably certain we would exercise these options.We also have two finance leases for copier equipment and computers in our facilities. On July 17, 2024, we exercised one of the two options to extend the current lease for our principal administrative and production facility for an additional period of five years commencing on January 1, 2027, and ending on December 31, 2031 ("Second Extended Lease Term"). All terms and conditions of the lease shall continue to apply during the Second Extended Lease Term. We will pay approximately $ 1.5 million in rent during the Second Extended Lease Term. The operating lease and finance lease components included in right-of-use assets, short-term lease liabilities and long-term lease liabilities on our consolidated balance sheets as of December 31, 2025 and 2024, are as follows: 2025 Operating Leases Finance Leases Right-of-use assets $ 861 $ 79 (1) Short-term lease liabilities $ 128 $ 39 Long-term lease liabilities $ 1,186 $ 42 2024 Operating Leases Finance Leases Right-of-use assets $ 1,210 $ 128 (1) Short-term lease liabilities $ 136 $ 78 Long-term lease liabilities $ 1,311 $ 18 _______________________ (1) Net of accumulated depreciation, included in property and equipment, net. 115 Table of Contents The components of lease expense for the years ended December 31, 2025 and 2024, were as follows: December 31, 2025 2024 Operating lease expense $ 310 $ 409 Finance lease expense: Amortization of ROU assets 29 115 Interest on lease liabilities 3 11 Total finance lease expense 32 126 Total lease expense $ 342 $ 535 Cash paid for amounts included in the measurement of lease liabilities for the years ended December 31, 2025 and 2024, were as follows: December 31, 2025 2024 Operating cash flows from operating leases $ 294 $ 441 Financing cash flows from finance leases $ 81 $ 84 Maturities of lease liabilities under noncancellable leases as of December 31, 2025, are as follows: Operating Leases Finance Leases 2026 $ 299 $ 46 2027 371 43 2028 300 1 2029 304 — 2030 316 — Thereafter 329 — Total undiscounted lease payments 1,919 90 Less imputed interest ( 605 ) ( 9 ) Total lease liabilities $ 1,314 $ 81 As of December 31, 2025, the weighted-average remaining lease term of our operating and finance leases is 5.5 years and 2.0 years, respectively. The weighted-average discount rate for operating and finance leases is 13.8 % and 11.6 %, respectively, which is based on interest rates we paid for our most recent term loan and convertible notes. As of December 31, 2024, the weighted-average life of our operating and finance leases was 6.0 years and 2.0 years, respectively. The weighted-average discount rate for operating and finance leases was 13.8 % and 8.1 %, respectively, which is based on interest rates we paid for our most recent term loan and convertible notes. (17) Commitments And Contingencies The Company maintains a salary reduction savings plan under Section 401(k) of the Internal Revenue Code, which we administer for participating employees’ contributions. All full-time employees are covered under the plan after meeting minimum service requirements. We paid matching contributions of $ 0.7 million and $ 0.7 million to the plan for the years ended December 31, 2025 and 2024, respectively. Our contributions were based on compensation at the rate of 3 %, 3.5 %, and 4 % for an employee’s contribution of up to 3 %, between 3 % and 4 %, and between 4 % and 5 %, respectively, with the match-eligible contribution being limited to 4 % of the employee’s eligible compensation. From time to time, we may have certain contingent liabilities, including litigation, which arise in the ordinary course of business activities. We accrue contingent liabilities when it is probable that future expenditures will be made and such expenditures can be reasonably estimated. In the opinion of management, there are no pending claims for which the outcome is expected to result in a material adverse effect on our consolidated balance sheets, statements of operations or statements of cash flows. 116 Table of Contents As part of the Business Combination, we entered into the Amended and Restated Registration Rights Agreement with certain investors in MTAC and Legacy TriSalus. Subject to certain requirements and customary conditions, we granted piggyback registration rights and demand registration rights to the parties thereto, agreed to pay certain expenses related to such registrations and agreed to indemnify the parties thereto against certain liabilities related to such registrations. Our registration obligations under the Amended and Restated Registration Rights Agreement will terminate with respect to any party thereto on the date that such party no longer holds any Registrable Securities (as defined in the Amended and Restated Registration Rights Agreement). The Amended and Restated Registration Rights Agreement does not contain liquidated damages or other cash settlement provisions resulting from delays in registering the Company’s securities. We are not a party to any legal proceedings and we are not aware of any claims or actions pending or threatened against us. In the future, we might from time to time become involved in litigation relating to claims arising from our ordinary course of business. (18) Subsequent Events On February 19, 2026, we entered into an underwriting agreement (the “Underwriting Agreement”) with Lake Street Capital Markets, LLC (“LSCM”), as representative of the underwriters named therein (the “Underwriters”), relating to the public offering (the “Offering”) of 9,756,100 shares (the “Shares”) of common stock of the Company, par value $ 0.0001 per share (the “Common Stock”), at a price to the public of $ 4.10 per Share (the “Offering Price”). Pursuant to the terms of the Underwriting Agreement, the Company 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. On February 23, 2026, the Offering closed, which resulted in the issuance of the Shares for net proceeds of approximately $ 37.0 million. Subsequent to the closing of the Offering, the Underwriters purchased the Option Shares which resulted in additional net proceeds of approximately $ 5.6 million. 117 Table of Contents Item 9.
