Notes to Condensed Consolidated Financial Statements

Note1. Organization and Nature of Operations

The Company

Catheter Precision, Inc. ("Catheter" or the "Company”) was incorporated in California on* September 4, 2002,and reincorporated in Delaware in July 2018.On January 9, 2023,*Catheter entered into the Amended and Restated Agreement and Plan of Merger (the "Merger Agreement") with Catheter Precision, Inc. (“Old Catheter”), a privately held Delaware corporation. Under the terms of the Merger Agreement, Old Catheter became a wholly owned subsidiary of Catheter, together referred to as the Company, in a stock-for-stock merger transaction (the "Merger"). The Company's operating activities primarily related to Old Catheter's historical business, which included the design, manufacture and sale of new and innovative medical technologies in the field of cardiac electrophysiology (“EP”).

On* February 6, 2026,the Company entered into an Acquisition Purchase Agreement with SEG Jets LLC ("SEG Jets"), whereby the Company agreed to acquire 19.98% of the issued and outstanding shares of common stock of Fly Flyte, Inc. ("FLYTE") held by SEG Jets. On March 9, 2026,the Company entered into an Acquisition Purchase Agreement with Creatd, Inc. ("Creatd") and acquired the remaining 80.02% of the issued and outstanding shares of common stock of FLYTE and all of FLYTE’s wholly owned consolidated subsidiaries, which included 100% equity ownership interest in Ponderosa Air, LLC. As a result of these transactions (collectively the "Acquisition"), the Company owns100%* of the issued and outstanding common stock of FLYTE and its wholly owned consolidated subsidiaries. FLYTE and all of its wholly owned consolidated subsidiaries operate as a single business.

After the Acquisition, the Company's operations are organized and managed undertwo reportable segments: (i) cardiac electrophysiology and (ii) private aviation.

Cardiac Electrophysiology Segment

One of the Company’stwo primary products under the cardiac electrophysiology segment is the VIVO System, which is an acronym for View into Ventricular Onset System (“VIVO” or “VIVO System”). VIVO is a non-invasive imaging system that offers3D cardiac mapping to help with localizing the sites of origin of idiopathic ventricular arrhythmias in patients with structurally normal hearts prior to EP procedures. The VIVO System is commercially available in the European Union and has been placed at several hospitals in Europe. United States Food and Drug Administration ("FDA")510(k) clearance was received, and the Company began commercial sales of VIVO in2021 in the United States.

The Company’ssecond primary product, LockeT® (“LockeT”), is a suture retention device indicated for wound healing by distributing suture tension over a larger area in the patient in conjunction with a figure ofeight suture closure and is intended to temporarily secure sutures and aid clinicians in locating and removing sutures efficiently. In addition, LockeT is a sterile, Class I product that was registered with the FDA in* February 2023,at which time initial shipments began to distributors. Clinical studies for LockeT began during the year ended December 31, 2023.These studies are planned to show the product’s effectiveness and benefits, including faster wound closure and patient ambulation/discharge, potentially resulting in higher procedural volumes and lower costs for the healthcare provider and/or insurance payor. This information is intended to provide crucial data that will improve marketability by establishing the effectiveness of the medical device and a competitive advantage. The Company recorded itsfirst* commercial sale of LockeT to distributors in* May 2024.In April 2025,a U.S. patent for the product was granted by the United States Patent and Trademark Office. In April 2025,*the Company also obtained the CE Mark approval for LockeT, permitting the marketing and sale of LockeT in the European Union, Switzerland and Turkey. Since receipt of the CE Mark, the Company has signed agreements with new distributors in the United Kingdom, Italy, Spain, Portugal, Switzerland, the Middle East, South Africa and Brunei.

The Company’s product portfolio also includes the Amigo® Remote Catheter System (the "AMIGO" or "AMIGO System"), a robotic arm that serves as a catheter control device. The Company owns the intellectual property related to AMIGO, and this product is under consideration for future research and development of asecond-generation product.

Private Aviation Segment

Through its wholly owned subsidiary, the Company operates a private aviation company providing regional private jet charter services primarily using its own fleet of Cirrus Vision airplanes. Charter customers are sourced through a network of brokers who make a market between customers and private aviation companies, and also through its recently launched Direct to Consumer app and website. The subsidiary’s business strategy includes providing low-cost private aviation compared to traditional charter services as an alternative to driving within the typical450-mile range of the Vision jet. The company’s recently launched app enables customers to quickly and easily book and pay for flights and has begun to create and increase brand awareness among the company’s target market of customers who choose to reduce the time required to travel to and from destinations with the speed of flight. The company has also recently launched the ability for customers to bid to fly on empty-leg segments intended to turn those segments into cost-neutral or profitable flights. During the remainder of2026 the company anticipates commencing operating flights to and from the Bahamas, Canada and Mexico.

Reverse Stock Split

On* July 25, 2025,at the Annual Meeting of Stockholders of the Company, the stockholders approved an Amendment to the Amended and Restated Certificate of Incorporation of the Company to effect a reverse stock split within specified parameters. The Board approved the Amendment and set the ratio of the reverse stock split at1*-for-19. The Amendment was effective* August 15, 2025,effecting a reverse stock split in which eachnineteen* (19) shares of the Company’s common stock, par value $0.0001 per share, issued and outstanding immediately prior to the effective time, automatically combined intoone (1) validly issued, fully paid and non-assessable share of the Company’s common stock, par value $0.0001 per share.

No fractional shares were issued as a result of the reverse stock split. Stockholders who would otherwise have been entitled to receive a fractional share were entitled to receive their pro rata portion of the net proceeds obtained from the aggregation and sale by the exchange agent of the fractional shares resulting from the reverse stock split (reduced by any customary brokerage fees, commissions and other expenses). All references to share and per share amounts for all periods presented in the unaudited condensed consolidated financial statements have been retrospectively restated to reflect the reverse stock split. All rights to receive shares of common stock under outstanding securities, including butnot limited to, warrants and options, were adjusted to give effect to the reverse stock split. Furthermore, proportionate adjustments were made to the per share exercise price and the number of shares of common stock that* may*be purchased upon exercise of outstanding warrants and stock options granted by the Company, and the number of shares of common stock reserved for future issuance under the Company’s Equity Incentive Plan.

On* April 15, 2026,the shareholders of the Company approved a proposal to amend the Company’s Amended and Restated Certificate of Incorporation to effect a reverse stock split. The proposal allows, but doesnot* require, the Board to effect a reverse stock split of the Company’s common stock at a reverse stock split ratio ofnot less than1-for-2 andnot greater than1-for-100. The Board hasnot yet effected this reverse stock split.

Going Concern

The unaudited condensed consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and settlement of liabilities in the normal course of business, and donot include any adjustments to reflect the possible future effects on the recoverability and classification of assets or amounts and classification of liabilities that* may*result from uncertainty related to its ability to continue as a going concern.

8

The Company has incurred recurring net losses from operations and negative cash flows from operating activities since inception. For thesix months ended* June 30, 2026*, the Company incurred$5.0 million in net losses and used$5.7 million in cash for operating activities. As of* June 30, 2026*, the Company had an accumulated deficit of$314.5 million, working capital deficit of$10.9 million, and cash and cash equivalents of$0.6 million.

Management expects operating losses and negative cash flows to continue for the foreseeable future. The Company needs to raise additional capital until it is able to generate revenues from operations sufficient to fund its research, development, and commercial operations.

On* February 6, 2026,the Company entered into a Securities Purchase Agreement with certain accredited investors for a private placement financing and issued an aggregate of (i)392,608 shares of the Company's common stock, par value $0.0001 per share, at a per share purchase price of $1.43 and (ii)1,617 shares of newly designated Series C-1 Convertible Preferred Stock, par value $0.0001 per share and stated value of $1,000 per share, for gross proceeds of $2.2 million, net of $0.2 million in issuance costs. The investors agreed to purchase newly designated Series C-2 and Series C-3 Convertible Preferred Stock, par value $0.0001 per share and stated value of $1,000 per share, under additional closings for aggregate gross proceeds of $1.6 million per closing. The additional closings are subject to certain closing conditions, including stockholder approval to issue shares of common stock in excess of 19.99% of the Company’s issued and outstanding shares of common stock and to effect a reverse stock split ("Stockholder Approval”) and, solely with respect to the closing of the Series C-3 Convertible Preferred Stock, declaration of the effectiveness of the Registration Statement filed for the resale of the common stock underlying the Series C-1, C-2, and C-3 Convertible Preferred Stock. The investors also have the right, butnot* the obligation, to purchase up to an aggregate of $39.2 million of Series C-4 Convertible Preferred Stock, par value $0.0001 per share, with stated value of $1,000 per share inone or more closings.

On* February 6, 2026,*the Company also agreed to lower the exercise price of existing warrants and the conversion price of the Series B Convertible Preferred Stock to $1.78 per share for certain holders as consideration for exercising the existing warrants, resulting in aggregate proceeds of $0.4 million.

On* March 9, 2026,the Company entered into an additional Securities Purchase Agreement with certain accredited investors for a private placement financing pursuant to which the investors agreed to purchase 1,853 shares of Series C-1 Convertible Preferred Stock for aggregate gross proceeds of $1.9 million, net of $0.1 million in issuance costs. The investors agreed to purchase newly designated Series C-2 and Series C-3 Convertible Preferred Stock under additional closings for aggregate gross proceeds of $1.9 million per closing. The additional closings are subject to closing conditions, including approval from the Company’s stockholders to issue shares of common stock in excess of 19.99% of the Company’s issued and outstanding shares of common stock and, solely with respect to the closing for the Series C-3 Convertible Preferred Stock, effectiveness of the Registration Statement filed to register the resale of common stock underlying the Series C-1, C-2, and C-3 Convertible Preferred Stock. The investors also have the right, butnot* the obligation, to purchase up to an aggregate of $39.2 million of Series C-4 Convertible Preferred Stock inone or more closings.

On* April 21, 2026,pursuant to the Securities Purchase Agreements dated February 6, 2026and March 9, 2026,*the Company issued an aggregate of 3,470 shares of the Company’s newly designated Series C-2 Convertible Preferred Stock for aggregate gross proceeds of $3.5 million, and net proceeds of approximately $3.2 million after deducting transaction costs of approximately $0.3 million.

On* July 15, 2026,pursuant to the Securities Purchase Agreements dated February 6, 2026and March 9, 2026,*the Company issued an aggregate of 3,470 shares of the Company’s newly designated Series C-3 Convertible Preferred Stock for aggregate proceeds of $3.5 million.

On* July 30, 2026,pursuant to the Securities Purchase Agreements dated February 6, 2026and March 9, 2026,*the Company issued an aggregate of 2,821 shares of the Company’s newly designated Series C-4 Convertible Preferred Stock for aggregate proceeds of $2.8 million.

Based on the Company's liquidity resources, there is substantial doubt about the Company’s ability to continue as a going concern within12 months from the date of issuance of the unaudited condensed consolidated financial statements. The accompanying unaudited condensed consolidated financial statements have been prepared on the basis of the Company continuing to operate in the normal course of business and donot reflect any adjustments to the assets and liabilities related to the substantial doubt of its ability to continue as a going concern.

9

Management plans to raise additional capital through public or private equity or debt financing, or other innovative and specialty finance strategies, in order to fulfill its operating and capital requirements for at least12 months from the date of the issuance of the unaudited condensed consolidated financial statements. However, the Company* may**not* be able to secure such financing in a timely manner or on favorable terms, if at all. Furthermore, if the Company issues equity securities to raise additional funds, its existing stockholders* mayexperience dilution, and the new equity securities may*have rights, preferences and privileges senior to those of the Company’s existing stockholders.

Note2. Summary of Significant Accounting Policies

Principles of Consolidation

The unaudited condensed consolidated financial statements of the Company include the accounts of the Company, Old Catheter, Cardionomix, KardioNav, FLYTE, and Ponderosa. All intercompany transactions have been eliminated in consolidation.

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP") applicable to interim financial statements. The Financial Accounting Standards Board (“FASB”) establishes these principles to ensure financial condition, results of operations, and cash flows are consistently reported. Any reference in these notes to applicable accounting guidance is meant to refer to the authoritative nongovernmental GAAP as found in the FASB Accounting Standards Codification ("ASC"). Certain footnotes and other financial information normally required by U.S. GAAP have been condensed or omitted in accordance with instructions to Form10-Q and Article8 of Regulation S-X. In the opinion of management, such statements include all adjustments which are considered necessary for fair presentation of the unaudited condensed consolidated financial statements of the Company. The operating results presented herein arenot necessarily an indication of the results that* maybe expected for the year. The unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements included in its Annual Report on Form10*-K for the year ended* December 31,2025, as filed with the Securities and Exchange Commission (“SEC”) on March 31, 2026.*

Reclassifications

Certain prior period financial statement amounts have been reclassified for consistency with the current period presentation. These reclassifications hadno effect on our previously reported results of operations or accumulated deficit. In the current period, the Company (i) separately discloses interest expense due to related parties in the consolidated statements of operations, and (ii) separately discloses amortization of operating right-of-use assets in the condensed consolidated statements of cash flows. For comparative purposes, amounts in the prior periods have been reclassified to conform to current period presentations.

Use of Estimates

The preparation of the unaudited condensed consolidated financial statements requires management 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 unaudited condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. The Company’s unaudited condensed consolidated financial statements are based upon a number of estimates including, butnot limited to, the allowance for credit losses, evaluation of impairment of long-lived assets, valuation of long-lived assets and their associated estimated useful lives, reserves for warranty costs, evaluation of probable loss contingencies, fair value of royalties payable due to related parties, fair value of contingent consideration recorded in connection with an asset acquisition, fair value of assumed liabilities, acquired assets, and consideration transferred in connection with a business combination, fair value of preferred stock issued, including valuation of the deemed dividend and contribution, fair value of warrants issued, fair value of deferred stock issuance liabilities, and fair value of equity and liability classified awards granted.

10

Concentrations of Credit Risk

The Company's financial instruments that are exposed to concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable during thesix months ended* June 30, 2026and2025*. The Company generally maintains cash and cash equivalent balances in various operating accounts at financial institutions with high quality credit ratings in amounts in excess of federally insured limits of*$250,000.* The Company hasnot experienced any losses related to its cash and cash equivalents and doesnot believe that it is subject to significant or unusual credit risk beyond the normal credit risk associated with commercial banking relationships. The Company hasno significant off-balance sheet risk, such as foreign exchange contracts, option contracts, or other hedging arrangements.

The Company extends credit to customers in the normal course of business. Concentrations of credit risk with respect to accounts receivable exist to the full extent of amounts presented in the condensed consolidated balance sheets. The Company doesnot require collateral from its customers to secure accounts receivable.

One customer represented 18% of total revenues for thethree months ended* June 30, 2026* andone customer represented 15% of total revenues for thesix months ended* June 30, 2026*. Three customers represented 11%,15%, and 36% of total revenues for thethree months ended* June 30, 2025*. Two customers represented 13% andone customer represented 38% of total revenues for thesix months ended* June 30, 2025*.

The Company hadfour andfive customers that individually accounted for more than10% of total accounts receivable included in the condensed consolidated balance sheets as of* June 30, 2026* and* December 31, 2025*, respectively. Two customers represented 19% and 20% of accounts receivable andtwo customers each represented 12%of accounts receivable as of* June 30, 2026*. Two customers represented 27% and 15%, andthree customers each represented 10% of accounts receivable as of* December 31, 2025*.

The Company isnot dependent on any single supplier for critical components.

Segment Reporting

Following the acquisition of FLYTE, the Company determined that it operates intwo reportable segments: (i) cardiac electrophysiology and (ii) private aviation. The Company’s cardiac electrophysiology segment includes all activities related to the marketing, sales, and development of medical technologies in the cardiac electrophysiology field, together with corporate level activities of Catheter Precision, Inc. that are reviewed by the CODM as part of this segment's results. While the commercial efforts that coordinate the marketing, sales, and distribution of the cardiac electrophysiology products are organized by geographic region and product, all of these activities are supported by a single corporate team and distribution channel. The Company’s private aviation segment includes all activities related to the marketing, sales, and delivery of private aviation services to customers through FLYTE. All of its operations are centrally managed within the United States by a single corporate team. The determination oftwo reportable segments is consistent with the condensed consolidated financial information available and regularly reviewed by the Company’s chief operating decision maker (“CODM”).

The CODM is the Company’s Chief Executive Officer, who reviews and evaluates net loss for each reportable segment, for purposes of assessing performance, making operating decisions, allocating resources and planning and forecasting for future periods. Segment asset measures arenot used as a basis for the CODM to evaluate the performance of or to allocate resources to the segments.

Cash and Cash Equivalents

The Company considers all highly liquid investments purchased with an original maturity date ofninety days or less at the date of purchase to be cash equivalents. Cash and cash equivalents primarily represent funds invested in readily available checking and money market accounts.

Investments in Marketable Securities

The Company accounts for its investments in equity securities pursuant to ASC321, Investments—Equity Securities ("ASC Topic321"). Equity securities with readily determinable fair values are initially recognized and subsequently measured at fair value, with realized and unrealized gains and losses recognized in the condensed consolidated statements of operations within unrealized gains and losses on marketable securities, net. Realized gains and losses are determined based on the difference between the proceeds received and the carrying value of the securities sold.

Fair Value Measurements

Fair value represents the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants and is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. Athree-tier fair value hierarchy is used to identify inputs used in measuring fair value as follows:

Level1 - Observable inputs that reflect quoted market prices (unadjusted) for identical assets or liabilities in active markets;

Level2 - Inputs other than the quoted prices in active markets that are observable either directly or indirectly in the marketplace for identical or similar assets and liabilities; and

Level3 - Unobservable inputs that are supported by little orno market data, which require the Company to develop its own assumptions.

Prepaid expenses, accounts receivable, accounts payable, accrued expenses, and short-term notes payable are reported on the condensed consolidated balance sheets at carrying value, which approximate fair value due to the short-term maturities of these instruments. Similarly, the carrying value of the notes payable approximate their fair value due to the associated effective interest rates of the debt instruments.

The following table details the fair value measurements within the fair value hierarchy of the Company’s financial instruments (in thousands):

Royalties Payable Due to Related Parties

The fair value measurement of royalties payable due to related parties includes significant unobservable inputs that arenot supported by any market data. Royalties payable due to related parties reflect the present value of estimated future royalty payments. The Company applies an internally developed, revenue adjusted discount rate ("RADR”) to discount back the forecasted royalty payments. The RADR is based on the Company’s weighted average cost of capital ("WACC”) adjusted for the product revenue’s risk profile. The risk-free rate used to determine the cost of equity for the RADR is adjusted to be commensurate with the term of the royalty agreements. Furthermore, the Beta and Risk Premium used to determine the cost of equity are also adjusted to reflect the product revenue's volatility. All other inputs for the RADR and the Company’s WACC are the same. See Note10**, Royalties Payable, for additional information over royalties payable due to related parties.

Convertible Notes Payable

The Company elected the fair value option to measure the convertible notes payable. The fair value of the convertible notes payable is determined using a probability weighted expected return model ("PWER model”) that values the convertible notes payable based on the discounted cash flows ofthree potential settlement outcomes: (i) the convertible notes payable will be converted into and settled in shares of common stock, (ii) the convertible notes payable’s principal and accrued interest will be paid in cash, and (iii) a dissolution scenario wherein the investor receives a partial payment based on a recovery rate. The conversion outcome incorporates a Monte Carlo simulation to estimate the Company’s common stock price at the expected conversion date and the number of shares issuable based on the variable conversion price. Aside from the probability of thethree potential settlement outcomes, the fair value measurement incorporates several significant unobservable inputs, including the recovery rate, implied equity volatility, expected term assumptions, simulated conversion price, and credit-risk adjusted discount rate. The convertible notes payable were settled in* June 2026,such that there isno remaining balance as of June 30, 2026.See Note9,* Notes Payable for additional information.

Deferred Consideration

The deferred consideration consisted oftwo components. Thefirst deferred consideration component arose from the Company's initial 19.98% minority equity interest in FLYTE on* February 6, 2026,and thesecond* component related to the subsequent acquisition of the remaining outstanding equity in FLYTE on* March 9, 2026.See Note3,* Business Combinations, for additional information. The Company was obligated to issue to the sellers an aggregate of 11,028 shares of the Company’s Series D Convertible Preferred Stock. In accordance with ASC Topic815, Derivatives and Hedging ("ASC Topic815"), this obligation failed to meet the equity classification criteria in ASC Topic815-40-25. Therefore, it didnot qualify for the scope exception from derivative accounting. This obligation was classified as a current liability on the condensed consolidated balance sheet and measured at fair value, with changes in fair value reflected in the condensed consolidated statements of operations. The deferred consideration was settled on* April 20, 2026,*when the Company issued 11,028 shares of Series D Convertible Preferred Stock to the sellers.

The deferred consideration was classified as a Level3 recurring liability because the valuation utilized certain unobservable inputs that were supported by little orno market data. The fair value of the Series D Convertible Preferred Stock was measured using the if converted method, which included contractual terms such as the number of units issued, the $1,000 issued stated value, and the contractual conversion price. The if converted method also utilized observable inputs, such as the underlying common stock price on the acquisition date and the period end remeasurement date, and incorporated unobservable inputs related to a 20% discount for lack of marketability.

The fair value of thefirst component of deferred consideration initially recorded on* February 6, 2026was approximately $5.3 million. Upon obtaining control of FLYTE on March 9, 2026,the Company recorded thesecond* component of the deferred consideration of approximately $5.8 million. The Company remeasured the total deferred consideration, resulting in a decrease in fair value of approximately $0.3 million and $2.9 million during thethree andsix months ended* June 30, 2026,*respectively. The change in fair value was recognized as a gain in the condensed consolidated statements of operations.

Deferred Stock Issuance Liability

On* June 28, 2026,the Company received advanced proceeds of $0.6 million from an investor in exchange for the future issuance of the Series C-3 Convertible Preferred Stock pursuant to the Securities Purchase Agreements dated February 6, 2026and March 9, 2026.*The issuance of the Series C-3 Convertible Preferred Stock is contingent upon the effectiveness of the registration rights agreement filed for the resale of the shares of common stock underlying the Series C-1, Series C-2, and Series C-3 Convertible Preferred Stock. The deferred stock issuance liability represents the Company's obligation to contingently issue 601 shares of Series C-3 Convertible Preferred Stock to the investor.

In accordance with ASC Topic815, Derivatives and Hedging ("ASC Topic815"), this obligation failed to meet the equity classification criteria in ASC Topic815-40-25. Therefore, it doesnot qualify for the scope exception from derivative accounting. This obligation is classified as a liability on the condensed consolidated balance sheet and measured at fair value, with changes in fair value reflected in the condensed consolidated statements of operations at each reporting period end under other expenses, net. The deferred stock issuance liability is classified as a current liability on the condensed consolidated balance sheets as it was settled withintwelve months of the balance sheet date. The deferred stock issuance liability was settled on* July 15, 2026,when the Company issued 601 shares of Series C-3 Convertible Preferred Stock pursuant to the Securities Purchase Agreements dated February 6, 2026and March 9, 2026to the investor. See Note20,* Subsequent Events, for additional information over the total number of shares of Series C-3 Convertible Preferred Stock issued pursuant to the Securities Purchase Agreements dated* February 6, 2026and March 9, 2026.*

The deferred stock issuance liability has been classified as a Level3 recurring liability because the valuation utilizes certain unobservable inputs that are supported by little orno market data. The fair value of the Series C-3 Convertible Preferred Stock is measured using the if converted method, which included contractual terms such as the number of shares issued, the $1,000 issued stated value, and the contractual conversion price. The if converted method also utilizes observable inputs, such as the underlying common stock price on the acquisition date and the period end remeasurement date, and incorporated unobservable inputs related to a 20% discount for lack of marketability.

The fair value of the deferred stock issuance liability initially recorded on* June 28, 2026was approximately $0.6 million. The Company remeasured the total deferred consideration as of June 30, 2026*, resulting in an increase in fair value of approximately $47 thousand, which was recognized under other expenses, net in the condensed consolidated statements of operations. As of* June 30, 2026*, the fair value of the deferred stock issuance liability was approximately $0.6 million.

Increases or decreases in the fair value of royalties payable due to related parties and deferred stock issuance liability can result from updates to assumptions. Judgment is used in determining these assumptions as of the initial valuation date and at each subsequent reporting period. Changes or updates to assumptions could have a material impact on the reported fair value, the change in fair value, and the results of operations in any given period.

Accounts Receivable and Allowances for Credit Losses

Accounts receivable consists of trade receivables recorded at invoiced amounts. Accounts receivable are presented net of any discounts and allowance for credit losses, are unsecured and donot bear interest. Accounts receivable are evaluated for collectability based on historical credit loss experience, adjusted for asset-specific risk characteristics, current economic conditions, and reasonable forecasts, including the probability of future collection and estimated loss rates based on aging schedules.

Changes in the estimated collectability of accounts receivable are recorded in the condensed consolidated statements of operations in the period in which the estimate is revised. Accounts receivable are written off as uncollectible after all means of collection are exhausted. Any subsequent recoveries are credited to the allowance for credit losses. As of* June 30, 2026* and* December 31, 2025*, the allowance for credit losses related to accounts receivable was immaterial.

Inventories

Inventories are stated at the lower of cost (determined by thefirst-in,first-out method) or net realizable value. Cost includes materials, labor, and manufacturing overhead related to the purchase and production of inventories. The Company reduces the carrying value of inventories for those items that are potentially in excess, obsolete or slow-moving based on changes in customer demand, technological developments or other economic factors.

Property and Equipment

Property and equipment are recorded at cost, less accumulated depreciation. Property and equipment are depreciated on a straight-line basis over their estimated useful lives as follows:

Machinery and equipment2 - 5 years
Computer hardware and software1 - 5 years
LockeT animation video3 years
VIVO DEMO/Clinical Systems1-5 years

The Company periodically reviews the residual values and estimated useful lives of each class of its property and equipment for ongoing reasonableness, considering the long-term views of their intended use and the level of planned improvements to maintain and enhance those assets. When assets are retired or otherwise disposed of, the cost and related accumulated depreciation are removed from their respective account balances, and any resulting gain or loss is recognized in the Company’s condensed consolidated statements of operations. The cost of repairs and maintenance is expensed as incurred, whereas significant renewals and betterments are capitalized.

Business Combination

The Company accounts for business combinations using the acquisition method of accounting in accordance with ASC Topic805, Business Combinations("ASC Topic805"). The purchase price of an acquisition is allocated to the underlying tangible and identifiable intangible assets acquired and liabilities assumed based on their respective estimated fair values as of the acquisition date. The excess of the purchase price over the estimated fair value of the identifiable net assets acquired is recorded as goodwill. Transaction costs related to business combinations, such as legal, accounting, valuation, and other professional or consulting fees, are expensed as incurred and included in selling, general and administrative expenses in the condensed consolidated statements of operations.

The Company* mayadjust the preliminary purchase price allocation, as necessary, for up toone* year after the acquisition closing date (the “measurement period”) as it obtains more information regarding asset valuations and liabilities assumed that existed at the acquisition date. Measurement period adjustments are recorded in the period in which the adjustments are determined.

16

Deferred tax assets and liabilities are recognized for the tax effects of temporary differences between the tax bases and the recognized amounts of assets acquired and liabilities assumed in accordance with ASC Topic740, Income Taxes("ASC Topic740").

Goodwill and Indefinite-Lived Intangible Assets

Goodwill and indefinite-lived intangible assets arenot amortized. Goodwill and indefinite-lived intangible assets are tested for impairment annually during thefourth quarter, or more frequently if events or changes in circumstances indicate that the carrying amount* may**not* be recoverable. The Company has the option tofirst assess qualitative factors to determine whether it is necessary to perform the quantitative impairment test. If the Company elects to bypass the qualitative assessment, or if the qualitative assessment indicates it is more likely thannot that the fair value of a reporting unit is less than its carrying amount, a quantitative test is performed. An impairment charge for goodwill is recognized for the amount by which the carrying amount of the reporting unit exceeds its fair value,not to exceed the total amount of goodwill allocated to that reporting unit. An impairment charge for indefinite-lived intangible assets is recognized for the amount by which the carrying amount of the indefinite-lived intangible asset exceeds its fair value.

The Company completed a qualitative assessment and determined that there wasno evidence of impairment to the balance of its goodwill and indefinite-lived intangible assets as of* June 30, 2026*. The Company didnot have goodwill nor indefinite-lived intangible assets as of* December 31, 2025.*

Impairment of Long-lived Assets

The Company periodically reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that such assets might be impaired and the carrying value of the long-lived assets* maynot* be recoverable. If events or changes in circumstances indicate that the carrying amount of an asset* maynot* be recoverable and the expected undiscounted future cash flows attributable to the asset are less than the carrying amount of the asset, an impairment loss equal to the excess of the assets carrying value over its fair value is recorded in the Company’s condensed consolidated statements of operations at that date.

There wereno impairment charges recorded as of* June 30, 2026* and2025.

Royalties Payable Due to Related Parties

The Company is obligated to pay royalties related to the sales of LockeT and AMIGO System under various royalty agreements executed by Old Catheter. The Company recognizes a liability for royalty fees incurred and payable based on actual sales of products under current portion of royalties payable due to related parties in the condensed consolidated balance sheets. The Company recognizes a liability for future, estimated royalty payments at fair value under current portion of royalties payable due to related parties in the condensed consolidated balance sheets if it is payable within the next12 months and under royalties payable due to related parties in the condensed consolidated balance sheets if it is payable12 months after the balance sheet date. The royalties payable due to related parties is remeasured at each reporting period. Changes in fair value of royalties payable due to related parties are recorded in the condensed consolidated statements of operations in the period in which they occur. See Note10, Royalties Payable for additional information.

17

Asset Acquisitions and In-process Research and Development

The Company accounts for acquisitions of assets or a group of assets that donot meet the definition of a business as asset acquisitions based on the cost to acquire the asset or group of assets, which includes certain transaction costs. In an asset acquisition, the cost to acquire is allocated to the identifiable assets acquired and liabilities assumed based on their relative fair values as of the acquisition date.No goodwill is recorded in an asset acquisition.

Assets that are acquired in an asset acquisition for use in research and development activities that have an alternative future use are capitalized as in-process research and development (“IPR&D”) in the condensed consolidated balance sheets. Acquired IPR&D that hasno alternative future use as of the acquisition date is recognized as acquired-in-process research and development expense in the condensed consolidated statements of operations as of the acquisition date.

Contingent consideration in asset acquisitions that isnot accounted for as a derivative is measured and recognized when payment becomes probable and reasonably estimable. Subsequent changes in the accrued amount of contingent consideration are measured and recognized at the end of each reporting period and upon settlement as an adjustment to the cost basis of the acquired asset or group of assets, or, if related to IPR&D withno alternative future use, recognized as expense. Contingent consideration that is in the form of a sales or usage-based royalty payment is recognized as an expense as incurred.

Debt Securities

Debt securities consist of the QHSLab Notes, which were received as partial consideration for the PIPE Units and Series B Convertible Preferred Stock issued by the Company under the* May 2025PIPE Financing (see Note13,* Equity Offerings for further details). One QHSLab Note was originally issued on* August 10, 2021with a principal amount of $806 thousand, a maturity date of August 10, 2022,an interest rate of 5% per annum, a default interest rate of 18%, and a conversion rate of 20 cents per share of common stock of QHSLab, Inc. (“QHSLab”). Thesecond* QHSLab Note was originally issued on* July 19, 2022with a principal amount of $440,000, a maturity date of July 19, 2023,*interest rate of 5% per annum, a default interest rate of 18%, and conversion rate of 20 cents per share of common stock of QHSLab. Both QHSLab Notes were in default at the date of transfer.

Under ASC Topic320, Investments: Debt Securities, debt securities are classified intoone ofthree categories upon acquisition: held-to-maturity, available-for-sale or trading. Debt securities that the Company has both the positive intent and ability to hold to maturity are classified as held to maturity. Debt securities that are bought and held principally for the purpose of selling them in the near term are classified as trading. All other debt securities are classified as available-for-sale. As the Company acquired the QHSLab Notes with the intent of selling them, the QHSLab Notes are classified as trading debt securities.

Trading debt securities are initially and subsequently measured at fair value in the condensed consolidated balance sheets, with unrealized holding gains and losses included in change in fair value of trading debt securities in the condensed consolidated statements of operations. The QHSLab Notes were valued at $864 thousand at the close of the* May 2025PIPE Financing. The Company recorded unrealized gains of $10 thousand for the QHSLab Notes for thethree* andsix months ended* June 30, 2025*, such that the QHSLab Notes were valued at $874 thousand as of* June 30, 2025*. In* November 2025,the Company sold the QHSLab Notes. The Company doesnot* hold any trading debt securities as of* December 31, 2025.*

Convertible Notes Payable

Convertible notes payable represent debt-host financial instruments whose embedded features must be assessed for bifurcation and separate accounting as derivative liabilities under ASC Topic815, unless the fair value option is elected to measure certain financial assets and liabilities at fair value under ASC Topic825, Financial Instruments("ASC Topic825”). The fair value option* may*be elected on a financial instrument-by-financial instrument basis and is irrevocable, unless a new election date occurs. The fair value option simplifies the accounting by requiring the entire financial instrument to be measured at fair value.

As permitted under ASC Topic825, the Company elected the fair value option to account for the convertible notes payable issued on* December 26, 2025 (see Note9,* Notes Payable). The Company records convertible notes payable at fair value with any changes in fair value recorded as a component of other income (expense), net in the consolidated statements of operations. The change in fair value of convertible notes payable includes interest expense accrued for the convertible notes payable. Any portion of the change in fair value that is attributed to a change in the convertible note payables’ credit risk is recognized as a component of other comprehensive income. As a result of applying the fair value option, any debt issuance costs related to the convertible notes payable were expensed as incurred and werenot deferred.

The convertible notes payable were settled in* June 2026,such that there isno* remaining balance as of* June 30, 2026.See Note9,* Notes Payable for additional information.

Variable Interest Entity

A variable interest entity ("VIE") is a legal entity that doesnot have sufficient equity at risk to finance its activities without additional subordinated financial support or is structured such that equity investors lack the ability to make significant decisions relating to the entity’s operations through voting rights or donot substantively participate in the gains or losses of the entity. The primary beneficiary has both the power to direct the activities of the VIE that most significantly impact the entity’s economic performance and the obligation to absorb losses or the right to receive benefits from the VIE that could potentially be significant to the VIE.

18

The Company evaluates its ownership, contractual relationships and other interests in entities to determine the nature and extent of the interests, whether such interests are variable interests and whether the entities are VIEs in accordance with ASC Topic810, Consolidation("ASC Topic810"). These evaluations can be complex and judgmental, involving the use of estimates and assumptions based on available information among other factors. Based on these evaluations, if the Company determines it is the primary beneficiary of a VIE, the Company consolidates the accounts of that VIE. The equity owned by other stockholders is presented, as applicable, as non-controlling interests in the accompanying condensed consolidated balance sheets, statements of operations, and statements of stockholders’ equity.

If a reconsideration event occurs under ASC Topic810, the Company performs an assessment to determine whether the entity continues to be a VIE, whether the Company still contains a variable interest in the VIE, and whether the Company continues to be or has become the primary beneficiary of the VIE.

Cardionomix

Cardionomix is a legal entity that was solely created to hold the assets of and to clinically develop and commercialize the CPNS System. The Company holds 82% of the voting, common stock, while the Company’s Chief Executive Officer and his affiliates hold 12%, and otherthird parties hold the remaining 6%. The Company determined that its controlling equity interest represents a variable interest in Cardionomix, which meets the definition of a VIE as it doesnot have sufficient equity at risk to finance its activities without additional subordinated financial support. Furthermore, the Company has determined that it is the primary beneficiary of the VIE as it has the power to direct the activities that most significantly impact the VIE’s economic performance through its controlling equity interest. The Company therefore consolidates the results of operations, assets, and liabilities of Cardionomix. The Company didnot transfer any assets in exchange for its controlling equity interest in Cardionomix, which didnot have any assets or liabilities at formation. Accordingly, the Company didnot record any gain or loss upon initial consolidation.

As of* June 30, 2026*, Cardionomix only had a note payable with a carrying value of $1.4 million that was issued in* May**2025* in connection with the asset acquisition. This note payable is presented under notes payable of variable interest entities, net of discount in the condensed consolidated balance sheets. Cardionomix doesnot hold any other material assets or liabilities as of* June 30, 2026*. Creditors of Cardionomix haveno recourse to the Company’s general credit and their claims are limited solely to the assets of Cardionomix. Unless Cardionomix can obtain its own dedicated financing, the Company doesnot currently intend to allocate capital to fund the clinical development of the acquired assets.

The minority equity interest holders are presented as non-controlling interests in the accompanying condensed consolidated balance sheets, statements of operations, and statements of stockholders’ equity.

19

KardioNav

KardioNav is a legal entity that was solely created to hold the assets of and to clinically develop and commercialize certain intellectual property related to new cardiac technology. The Company holds 57% of the voting common stock, while the Company’s Chief Executive Officer and his affiliates hold 10%, and otherthird parties hold the remaining 33%. The Company determined that its controlling equity interest represents a variable interest in KardioNav, which meets the definition of a VIE as it doesnot have sufficient equity at risk to finance its activities without additional subordinated financial support. Furthermore, the Company has determined that it is the primary beneficiary of the VIE as it has the power to direct the activities that most significantly impact the VIE’s economic performance through its controlling equity interest. The Company therefore consolidates the results of operations, assets, and liabilities of KardioNav. The Company assigned certain intellectual property related to the VIVO System to KardioNav, which was accounted for as a common control transaction under ASC Topic810 and carried at the Company's carrying value at inception. Furthermore, the fair value of the intellectual property assigned by Chelak to KardioNav was deemed to be de minimis as the intellectual property solely consists of patents and related know-how at the conceptual stage. Therefore, the Company recognizedno gain or loss upon initial consolidation. Creditors of KardioNav haveno recourse to the Company’s general credit and their claims are limited solely to the assets of KardioNav. Unless KardioNav obtains its own financing, the Company currently intends, to the extent it is able and subject to changes in circumstances, to provide financial support to KardioNav, until such time as KardioNav* may*have successfully completed research and development of its cardiac electrophysiology mapping technologies.

As of* June 30, 2026*, KardioNav's only assets or liabilities relate to short-term notes payable of variable interest entities due to related parties with a carrying value of $312 thousand included in the condensed consolidated balance sheets. KardioNav doesnot hold any other material assets or liabilities.

The minority equity interest holders are presented as non-controlling interests in the accompanying condensed consolidated balance sheets, statements of operations, and statements of stockholders’ equity.

Distinguishing Liabilities from Equity

The Company evaluates equity or liability classification for freestanding financial instruments, including convertible preferred stock, warrants, and options, pursuant to the guidance under ASC Topic480, Distinguishing Liabilities from Equity (“ASC Topic480”). The Company classifies as liabilities all freestanding financial instruments that are (i) mandatorily redeemable, (ii) represent an obligation to repurchase the Company’s equity shares by transferring assets, or (iii) represent an unconditional obligation (or conditional obligation if the financial instrument isnot an outstanding share) to issue a variable number of shares predominantly based on a fixed monetary amount, variations in something other than the fair value of the Company’s equity shares, or variations inversely related to changes in fair value of the Company’s equity shares.

If a freestanding financial instrument doesnot represent an outstanding equity share and doesnot meet liability classification under ASC Topic480, the Company then assesses whether the freestanding financial instrument is indexed to its own stock and meets equity classification pursuant to ASC Topic815-40. The Company further assesses whether the freestanding financial instruments should be classified as temporary equity. Freestanding financial instruments that are redeemable for cash or other assets at a fixed or determinable date, at the option of the holder, or upon the occurrence of an event are classified in temporary equity in accordance with ASC Topic480. Otherwise, the freestanding financial instruments are classified in permanent equity.

See Note13, Equity Offerings and Note14, Preferred Stock for additional information on the freestanding financial instruments assessed under ASC Topic480 and ASC Topic815-40 for equity or liability classification.

Revenue Recognition

In accordance with ASC Topic606, Revenue from Contracts with Customers (“ASC Topic606”), the Company accounts for contracts with customers when there is a legally enforceable contract, the rights of the parties are identified, the contract has commercial substance, and collectability of the contract consideration is probable. Revenue is measured as the amount of consideration expected to be received in exchange for transferring promised goods or services. The amount of consideration to be received and revenue recognized* mayvary due to discounts. A performance obligation is a promise in a contract to transfer a distinct good or service. If there are multiple performance obligations in the customer contract, the Company allocates the transaction price in the contract to each performance obligation based on the relative standalone selling price. The Company doesnot* adjust revenue for the effects of a significant financing component for contracts if the period between the transfer of control and corresponding payment is expected to beone year or less. Revenue is recognized when performance obligations in the customer contract are satisfied. This generally occurs when the customer obtains control of a promised good at a point in time or when a customer receives a promised service over time.

Pursuant to ASC Topic606, the Company applies the followingfive steps to each customer contract:

Step1: Identify the contract with the customer

Step2: Identify the performance obligations in the contract

Step3: Determine the transaction price

Step4: Allocate the transaction price to the performance obligations in the contract

Step5: Recognize revenue when the Company satisfies a performance obligation

The Company has elected as a practical expedient to expense as incurred any costs incurred to obtain a contract as the related amortization period would beone year or less.

VIVO System

The VIVO System offers3D cardiac mapping to help localize the sites of origin of idiopathic ventricular arrhythmias in patients with structurally normal hearts prior to electrophysiology studies. Customers are provided with VIVO Positioning Patch Sets, which are custom patches, that are used in conjunction with the VIVO System. The VIVO Positioning Patch Sets are integral to the functionality of the VIVO System. The VIVO System, including the VIVO Positioning Patch Sets, represents the Company’s primary performance obligation. The Company recognizes revenue when physical possession and control of the VIVO System is transferred to the customer upon delivery. The Company also offers customers software upgrades for the VIVO System, which* maybe purchased and paid in advance at contract inception. Software upgrades represent stand-ready services, whereby the Company promises to provide software upgrades to the customer when and as upgrades are available. Software upgrade services maybe offered for initial contract terms ofone* to multiple years. Customers have the option to renew software upgrades services at the end of each term. The software upgrade services represent the Company'ssecond performance obligation, which is recognized evenly over time over the contract term.

The Company invoices the customer for the VIVO System and related software upgrades after physical possession and control of the VIVO System has been transferred to the customer. Subsequent renewals for software upgrades are invoiced at inception of the renewed term. The timing of payment for the corresponding invoices depends on the credit terms identified in each customer contract. There wereno software upgrade services revenues during thesix months ended* June 30, 2026and2025*.

21

LockeT

The LockeT device represents a performance obligation in the customer contract. The Company recognizes revenue when it transfers control of the LockeT device to the customer, which happens when the Company delivers the product to the customer.

Private Aviation Charter Services

The Company generates revenue throughtwo primary private aviation services: Hops and Luxe.

Hops refers to Flyte’s short-haul private charter service, through which Flyte arranges charter routes using leased jets and pilots dedicated to Flyte’s operations. These flights are conducted on Company-managed aircraft and typically service high-demand regional routes throughout the New York Metro Area, Long Island, New England and the Eastern seaboard, to any destination within400 nautical miles of the Company’s base in Farmingdale, New York. Each flight represents a performance obligation. For Hops arrangements, the Company acts as the principal because it controls the specified flight service before it is transferred to the customer, is primarily responsible for operating and fulfilling the flight, and has discretion in establishing pricing. Accordingly, Hops revenue is presented on a gross basis in the condensed consolidated statements of operations. Revenue includes base charter rates, repositioning fees, and ancillary charges.

Luxe is the Company’s brokerage division, offering clients access to on-demand charters through a vetted network of independentthird-party aircraft operators. For Luxe arrangements, the Company evaluates whether it controls the specified flight service before it is transferred to the customer or whether the Company’s performance obligation is to arrange for athird-party operator to provide the flight service. The Company has determined that it acts as an agent in Luxe arrangements because thethird-party aircraft operator is primarily responsible for operating and fulfilling the flight, and the Company doesnot control the underlying flight service before it is provided to the customer. Accordingly, Luxe revenue is presented on a net basis in the condensed consolidated statements of operations and represents the commission, brokerage fee, or other net amount retained by the Company after amounts payable to thethird-party aircraft operator.

For both Hops and Luxe, flights are earned and recognized as revenue at the point in time in which the service is provided, representing the satisfaction of the performance obligation. The Company generally doesnot issue refunds for flights unless there is a failure to meet its service obligations. For roundtrip flights, revenue is recognized upon arrival at the destination for each flight. Customer payments received in advance are recorded as deferred revenue until the related performance obligation is satisfied.

Deferred Revenue

Deferred revenues primarily consist of contract liabilities and represent amounts billed to, or collected from, customers in advance of the Company satisfying the related performance obligations. The Company recognizes revenue from deferred revenue as the related products or services are transferred to customers in accordance with the terms of the underlying customer contract.

The Company’s contract liabilities were assumed in connection with the acquisition of FLYTE and relate to customer arrangements of the acquired business for which consideration had been received, or amounts had been billed, prior to the satisfaction of the related performance obligations. The Company had de minimis contract liabilities prior to the acquisition of FLYTE. As of* June 30, 2026*, the Company hadno contract assets related to contracts with customers. Deferred revenue is presented as a current liability in the condensed consolidated balance sheets to the extent the Company expects to recognize the related revenue within the nexttwelve months.

Shipping and Handling Costs

Shipping and handling costs charged to customers are included in net product sales, while all other shipping and handling costs are included in selling, general and administrative expenses in the accompanying unaudited condensed consolidated statements of operations.

Advertising and Marketing

Advertising costs are expensed as incurred and included in selling, general and administrative expenses in the unaudited condensed consolidated statements of operations. Advertising costs were $207 thousand and $233 thousand during thethree andsix months ended* June 30, 2026*, respectively, $50 thousand and $133 thousand during thethree andsix months ended* June 30, 2025*, respectively.

23

Patents

The Company expenses patent costs, including related legal costs, as incurred and records such costs as selling, general and administrative expenses in the accompanying unaudited condensed consolidated statements of operations.

Research and Development

Major components of research and development costs include consulting, research grants, supplies and clinical trial expenses. Research and development expenses are charged to operations in the period incurred.

Stock-based Compensation

The Company recognizes stock-based compensation expense associated with stock options, restricted stock awards (“RSAs”) and restricted stock units (“RSUs”) issued to employees, members of the Company’s board of directors and consultants in accordance with ASC Topic718, Compensation–* Stock Compensation* (“ASC Topic718”). The Company evaluates whether stock-based awards should be classified and accounted for as liability or equity awards on the date of grant. Furthermore, the Company measures all stock-based awards granted based on their fair value on the date of grant. Stock options are measured at fair value using the Black-Scholes option pricing valuation model (the “Black-Scholes model”), which incorporates various assumptions, including expected term, volatility and risk-free interest rate. The expected term of the options is the estimated period of time until exercise and was determined using the SEC’s safe harbor rules, using an average of vesting and contractual terms, as the Company didnot have sufficient historical experience of similar awards. Expected stock price volatility is based on historical volatilities of certain “guideline” companies, as the Company doesnot have sufficient historical stock price data. The risk-free interest rate is based on the implied yield available on U.S. Treasuryzero-coupon issues with an equivalent term. Stock-based compensation expense for all stock-based awards is recognized over the requisite service period, which is generally the vesting period of the respective stock award. Stock-based compensation expense for stock-based awards with a performance condition is recognized when the achievement of such performance condition is determined to be probable. If the outcome of such performance condition isnot probable or isnot met,no stock-based compensation expense is recognized, and any previously recognized compensation expense is reversed. Forfeitures are recognized as a reduction of stock-based compensation expense as they occur.

Income Taxes

The Company accounts for income taxes using the asset and liability method. Under this method, deferred tax assets and liabilities are determined based on differences between the financial reporting and tax basis of assets and liabilities and are measured using enacted tax rates and laws that are expected to be in effect when the differences reverse. Any resulting net deferred tax assets are evaluated for recoverability and, accordingly, a valuation allowance is provided when it is more likely thannot that all or some portion of the deferred tax asset willnot be realized.

The Company accounts for uncertainty in income taxes using atwo-step approach to recognizing and measuring uncertain tax positions. Thefirst step is to evaluate the tax position for recognition by determining whether it is more likely thannot that the position will be sustained on an audit, including resolution of related appeals or litigation processes, if any. Thesecond step is to measure the tax benefit as the largest amount that is more than50% likely of being realized upon ultimate settlement. An uncertain tax position is considered effectively settled on completion of an examination by a taxing authority if certain other conditions are satisfied. Should the Company incur interest and penalties relating to tax uncertainties, such amounts would be classified as a component of interest expense and other income (expense), net respectively.

On* July 4, 2025,the One Big Beautiful Bill Act was signed into law. The legislation didnot* have a material impact on our income tax expense for thesix months ended* June 30, 2026*.

Basic and Diluted Net Loss per Share

Earnings per share attributable to Catheter Precision, Inc. common stockholders is calculated using thetwo-class method, which is an earnings allocation formula that determines earnings per share for the holders of the Company’s common shares and participating securities. The Company’s SeriesX Convertible Preferred Stock, of whichno shares were outstanding as of* June 30, 2026*, as well as Series B Convertible Preferred Stock, Series C Convertible Preferred Stock, Series D Convertible Preferred Stock, Series J Convertible Preferred Stock, and outstanding warrants are participating securities as they contain participating rights in distributions made to common stockholders. Since the participating securities donot include a contractual obligation to share in the losses of the Company, they arenot included in the calculation of net loss per share in the periods that have a net loss. In addition, common stock equivalent shares (whether ornot participating) are excluded from the computation of diluted loss per share in periods in which they have an anti-dilutive effect on net loss per common share.

Diluted net loss per share is computed using the more dilutive of (a) thetwo-class method or (b) the if-converted method and treasury stock method, as applicable. In periods in which the Company reports a net loss attributable to Catheter Precision, Inc. common stockholders, diluted net loss per share attributable to Catheter Precision, Inc. common stockholders is the same as basic net loss per share attributable to Catheter Precision, Inc. common stockholders since dilutive common shares arenot assumed to have been issued if their effect is anti-dilutive. Diluted net loss per share is equivalent to basic net loss per share for the periods presented herein because common stock equivalent shares from outstanding warrants, stock options, Series B Convertible Preferred Stock, Series C Convertible Preferred Stock, Series D Convertible Preferred Stock, and Series J Convertible Preferred Stock were anti-dilutive (see Note12, Net Loss per Share).

Net loss attributable to Catheter Precision, Inc. common stockholders consists of net income or loss attributable to Catheter Precision, Inc., as adjusted for actual and deemed dividends declared, if applicable.

Note3. Business Combination

On* February 6, 2026,the Company entered into an Acquisition Purchase Agreement with SEG Jets, whereby the Company agreed to acquire 19.98% of the issued and outstanding shares of common stock of FLYTE. The Company was obligated to issue to the sellers an aggregate of 5,250 shares of the Company’s Series D Convertible Preferred Stock which was recorded as thefirst* component of deferred consideration as of* February 6, 2026.*

On* March 9, 2026,the Company entered into an Acquisition Purchase Agreement with Creatd and acquired the remaining 80.02% of the issued and outstanding shares of common stock of FLYTE and 100% of the membership interests of Ponderosa. The Company was obligated to issue to the sellers an aggregate of 5,778 additional shares of the Company’s Series D Convertible Preferred Stock, which was recorded as thesecond* component of deferred consideration as of* March 9, 2026.*The purpose of the Acquisition was to acquire FLYTE’s and Ponderosa’s operations related to aviation, assets, and technology platform.

After obtaining a controlling interest in FLYTE, the Company remeasured its previously held minority equity interest to fair value as of the Acquisition date and recorded a change in fair value of minority equity interest of $2.3 million in the condensed consolidated statements of operations. This effectively reduced the fair value of the minority equity interest from $5.2 million to $2.9 million as of the Acquisition date. The fair value of the investment was determined based on the implied transaction value of FLYTE, which was derived from the purchase price paid to acquire the remaining 80.02% interest in FLYTE.

In consideration for the Acquisition, the Company paid cash at closing, settled certain indebtedness on behalf of the seller, issued a short-term promissory note, and recorded the deferred consideration obligation to issue 5,778 additional shares of the Company’s Series D Convertible Preferred Stock. The total purchase consideration for the Acquisition was $14.8 million, which consists of the following estimated fair value amounts (in thousands):

DescriptionFair Value
Cash proceeds to seller$685
Fair value of promissory note4,788
Payment of indebtedness554
Fair value of previously held minority equity interest of step acquiree2,948
Fair value of deferred consideration5,778
Total purchase price$14,753

The Acquisition is being accounted for as a business combination in accordance with ASC Topic805. The Company estimated the fair values of the assets acquired and liabilities assumed in the Acquisition. These values have been prepared based on preliminary estimates of the fair value of the consideration paid, assets acquired, and liabilities assumed. The Company hasnot yet completed its evaluation and determination of certain assets acquired and liabilities assumed, primarily the final valuation of goodwill and intangible assets; therefore, the final fair value of the assets acquired and liabilities assumed, which will be completed within the measurement period of up toone year from the acquisition date,* mayvary from the Company’s preliminary estimates. The Company will continue to evaluate and refine the allocation based on additional information obtained during the measurement period in accordance with ASC805.*

26

During the measurement period, there were changes to the preliminary purchase price allocation based on adjustments to the fair value of the acquired assets and assumed liabilities. The measurement period adjustment didnot have a material impact on the condensed consolidated statements of operations. The following table summarizes the preliminary purchase price allocations relating to the Acquisition as of the Acquisition date and related adjustments thereafter (in thousands):

On* May 30, 2024,*David A. Jenkins loaned $500,000 to the Company in exchange for a short-term promissory note.

On* June 25, 2024,*an entity controlled by Mr. Jenkins loaned $150,000 to the Company in exchange for a short-term promissory note.

On* July 1, 2024and July 18, 2024,the Company entered intotwo* short-term promissory notes with an affiliate of Mr. Jenkins, wherein the affiliate loaned $250,000 and $100,000, respectively, to the Company in exchange for the short-term promissory notes.

All of these short-term promissory notes (the “Related Party Notes”) had a maturity date of* August 30, 2024*and interest of 8% per annum.

On* August 23, 2024,the Company entered into thefirst* amendment of the Related Party Notes, which extended the maturity date to* January 31, 2026and increased the interest rate to 12% per annum after August 31, 2024.All other terms and conditions remained substantially unchanged. As part of the amendment, the Company paid down all accrued interest to date of $21 thousand. The amendment was accounted for as a debt modification in accordance with ASC Topic470*-50, Debt Modifications and Extinguishment(“ASC Topic470-50”). Since the modified terms and conditions werenot substantially different from the prior terms and conditions, the Company accounted for the debt modification as a continuation of the original debt instrument. The Company further concluded that the debt modification didnot result in any adjustments to the carrying value of the Related Party Notes.

In accordance with ASC Topic470-50, the Company derecognized the net carrying amount of the original Related Party Notes and recorded the amended Related Party Notes at fair value. Since the fair value of the amended Related Party Notes of $1.7 million was greater than the principal balance of $1.5 million, the Company recognized a premium of $0.2 million as of* December 31, 2025*. The difference between the reacquisition price, which is the sum of the fair values of the amended Related Party Notes, Perikard membership interests, and Series M Warrants, and the net carrying amount of the original Related Party Notes of $0.6 million was recorded as loss on debt extinguishment in the consolidated statement of operations for the year ended* December 31, 2025*.

Note10. Royalties Payable

LockeT Royalty

On* January 9, 2023,prior to the consummation of the Merger, Old Catheter entered in an agreement with its Convertible Promissory Noteholders (“Noteholders”), which substantially consisted of amounts due to David A. Jenkins, previously Old Catheter's Chairman of the Board of Directors prior to the Merger, and, currently, the Company’s Executive Chairman of the Board of Directors and Chief Executive Officer, to forgive all accrued interest and future interest expense in exchange for a future royalty right. Under these agreements, the Company is obligated to pay the Noteholders a total royalty equal to 11.82% of net sales of its LockeT device on a quarterly basis, commencing upon thefirst* commercial sale, which occurred in* April 2024,through December 31, 2035.*

In* April 2025,a US patent was granted by the United States Patent and Trademark Office, after which the Company is obligated to pay an additional royalty of 2% of net sales only after the initial $1 million of 5% royalties has been paid, up to a maximum of $10 million in additional royalties. These royalty payments apply to revenues through December 31, 2033*and will terminate at that date regardless of whether the full $10 million has been paid.

On* December 31, 2025,the Company entered into the Series J Exchange Agreement ("Exchange Agreement") with Mr. Jenkins and FatBoy Capital, L.P. to exchange future and accrued royalty rights of $2.7 million for an aggregate of 9,490 shares of the Company's newly designated Series J Convertible Preferred Stock, par value $0.0001 per share and stated value of $1,000 per share (see Note14,* Preferred Stock, for additional information). The Exchange Agreement was accounted for as an extinguishment of liabilities as the Company settled an outstanding contractual obligation through the issuance of shares of preferred stock. Therefore, the Company derecognized $2.7 million of royalties payable due to related parties and recognized the fair value of the Series J Convertible Preferred Stock of $5.3 million in additional paid-in capital for the year ended* December 31, 2025.The difference between the fair value of the Series J Convertible Preferred Stock and the fair value of the royalties payable due to related parties of $2.6 million was recorded as loss on debt extinguishment in the consolidated statement of operations for the year ended December 31, 2025.*

All other royalties payable remain outstanding and are included under current portion of royalties payable due to related parties and royalties payable due to related parties in the condensed consolidated balance sheets. As of* June 30, 2026* and* December 31, 2025*, the fair value of the royalty payable related to the agreement with the Noteholders was $0.8 million. The Company recordedno change in the fair value of the royalties payable due to related parties during thethree andsix months ended* June 30, 2026*. The Company recorded a loss of $1.7 million and$2.8 million for thethree andsix months ended* June 30, 2025*, respectively.

The Company accrued $20 thousand and $51 thousand under current portion of royalties payable due to related parties as of* June 30, 2026*, and* December 31, 2025*, respectively. These amounts represent actual royalty liabilities incurred and accrued by the Company as well as estimated future royalty payments payable within the next12 months.

The Company isnot actively marketing and selling the AMIGO System, such that there wasno royalty expense recorded for thethree andsix months ended* June 30, 2026and2025* in relation to the AMIGO System.

Note11. Leases

The Company determines if an arrangement contains a lease at contract inception based on its ability to control a physically distinct asset in exchange for consideration. If the arrangement contains a lease, the Company then determines the classification of the lease as either operating or finance. For thesix months ended* June 30, 2026*, and the year ended* December 31, 2025*, the Company only had operating leases.

For operating leases, right-of-use (“ROU”) assets and lease liabilities are initially recognized based on the present value of the future minimum lease payments over the lease term at the commencement date. The present values of future lease payments are discounted using the interest rate implicit in the lease if it is readily determinable. As most leases donot provide an implicit rate, the Company applies an incremental borrowing rate based on the information available at commencement date to determine the present value of future lease payments over the lease term. The Company benchmarked itself against other companies with similar credit ratings and of comparable quality to derive an incremental borrowing rate. Lease expense is recognized on a straight-line basis over the lease term in the condensed consolidated statements of operations.

The Company elected to utilize the short-term lease exemption to exclude recognition of ROU assets and lease liabilities from the condensed consolidated balance sheet for leases with an initial term of12 months or less, with payments instead being expensed on a straight-line basis over the lease term. If a lease includes options to extend the lease term, the Company doesnot assume the option will be exercised in its initial lease term assessment unless there is reasonable certainty that the Company will renew based on an assessment of economic factors present as of the lease commencement date. The Company monitors its plans to renew its material lease each reporting period.

The Company enters into contracts that contain both lease and non-lease components. Non-lease components include costs that donot provide a right-to-use a leased asset but instead provide a service such as maintenance costs. The Company has elected to account for the lease and non-lease components together as a single component for all classes of underlying assets. Variable costs associated with the lease, such as maintenance and utilities, arenot included in the measurement of ROU assets and liabilities. Variable costs are expensed when the events determining the amount of variable consideration to be paid have occurred.

FLYTE Leases

In connection with the acquisition of FLYTE, the Company assumed or entered into certain operating leases related to FLYTE’s aviation operations, including hangar, office space and aircraft leases. The Company evaluated each assumed or newly executed lease arrangement upon acquisition or commencement and recognized operating lease right-of-use-assets and operating lease liabilities for leases with remaining terms greater than12 months. For leases acquired in connection with the FLYTE acquisition, the Company measured the lease liabilities as if the acquired leases were new leases of the Company at the acquisition date, using the Company’s incremental borrowing rate when the rate implicit in the lease wasnot readily determinable. The FLYTE lease agreements generally require fixed monthly payments, payable in advance, and donot include residual value guarantees or purchase options that the Company is reasonably certain to exercise.

Hangar and Office Space Lease

Note13. Equity Offerings

**** May 2025**** PIPE Financing

On* May 12, 2025,the Company entered into a Securities Purchase Agreement for a private placement withthree* institutional investors (* “May 2025PIPE Financing”). Pursuant to the Securities Purchase Agreement, the Company sold an aggregate of (i)1,500 PIPE Units and (ii)1,500 additional shares of a new series of the Company’s preferred stock, designated Series B Convertible Preferred Stock, par value $0.0001 per share. Each PIPE Unit consisted of (i)one share of Series B Convertible Preferred Stock and (ii) Series L common stock purchase warrants ("Series L Warrants") to purchase approximately 150 shares of common stock at an exercise price of $9.50 per share. As consideration for the PIPE Units and Series B Convertible Preferred Stock, the Company collected gross proceeds of $1.5 million in cash and the QHSLab Notes, which had an initial fair value of $864 thousand as of the closing date, previously held byone* of the investors, before deducting placement agent fees and offering expenses of $0.4 million (collectively, the “Placement Agent Fees”).

The Series L Warrants werenot exercisable until stockholders' approval was obtained ("Stockholder Approval"), and expire 5.5 years thereafter. Each Series L Warrant is exercisable intoone share of the Company's common stock and* maybe exercised on a cashless basis under certain circumstances. The exercise price of the Series L Warrants is subject to appropriate adjustment in the event of recapitalization events, stock dividends, stock splits, stock combinations, reclassifications, reorganizations or similar events affecting the Company's common stock. The Series L Warrants are callable by the Company for $0.19 per share if the volume-weighted average price of the Company's common stock for20* consecutive trading days exceeds $28.50 per share and the Series L Warrants havenot been exercised. Stockholder approval was obtained on* July 25, 2025.*

In the event of certain transactions resulting in a change in control, at the option of the holder, the Company shall repurchase the Series L Warrants for an amount of cash equal to the Black Scholes Value of the unexercised portion of the Series L Warrants. However, if the change of control isnot within the Company’s control, then the holders shall receive the same type of consideration offered to the Company’s common stockholders at the Black Scholes Value of the unexercised portion of the Series L Warrant. If the Company’s common stockholders can choose the type of consideration (i.e., cash, stock, or other assets) to be received, then the Holders shall have the same choice. If the Company’s common stockholders donot receive any consideration, they are deemed to receive common stock of the successor entity.

In the event of certain restructuring or disposal events, then upon the subsequent exercise of the Series L Warrants, for each share of common stock that would have been issuable upon exercise immediately prior to the event, the holders shall receive the number of shares of common stock of the successor entity and any alternate consideration given to common stockholders. The exercise price shall be adjusted to apply to such alternate consideration based on the amount of alternate consideration issuable forone share of common stock. If holders of common stock are given any choice as to the securities, cash or property to be received for alternate consideration, then the holder shall be given the same choice.

Subject to limited exceptions, the holders of Series L Warrants, willnot have the right to exercise any portion of the warrant if the holder (together with such holder’s affiliates) would beneficially own a number of shares of common stock in excess of 4.99% of the shares of common stock then outstanding (the “Beneficial Ownership Limitation”). At the holder’s option, the holder* mayincrease the Beneficial Ownership Limitation to 9.99% of the shares of common stock then outstanding, with any such increase becoming effective upon61* days’ prior notice to the Company.

In connection with the* May 2025PIPE Financing, the Company also issued Placement Agent Warrants to purchase an aggregate of 13,534 shares of common stock at an exercise price of $10.3075 per share to the Placement Agent. The Placement Agent Warrants terminate 5 years from the date of issuance. The Placement Agent Warrants arenot* callable by the Company. Except for the exercise price, contract term, call option, and change in control provision, the Placement Agent Warrants have the same terms and conditions as the Series L Warrants.

The Company assessed the Series L Warrants and Placement Agent Warrants issued in connection with the* May 2025PIPE Financing and determined that they donot* require liability classification pursuant to ASC Topic480. Furthermore, the Series L Warrants and Placement Agent Warrants donot have any net cash settlement provisions that would preclude equity classification under ASC Topic815-40. Accordingly, the Series L Warrants and Placement Agent Warrants were recorded to additional paid-in capital in the condensed consolidated balance sheets.

See Note14, Preferred Stock for additional information on the Series B Convertible Preferred Stock issued by the Company in connection with the* May 2025*PIPE Financing.

In addition, the Company entered into a registration rights agreement with the investors requiring the Company to register for resale the shares of common stock issuable upon the conversion of the Series B Convertible Preferred Stock and Series L Warrants. Failure to maintain the registration shall lead to an obligation to pay to the investors cash liquidated damages equal to 2% of each investor’s subscription amount for then outstanding securities for every30-day period the lapse continues, with unpaid amounts accruing interest at 18% per annum after a specified grace period.

On* May 21, 2025,the Company filed the registration statement on Form S-3 for the resale of shares of common stock issuable upon the conversion of the Series B Convertible Preferred Stock and Series L Warrants, and it was declared effective on May 30, 2025.It isnot* probable that the Company will be obligated to make payments under the registration rights agreement as of* June 30, 2026*.

Note16. Asset Acquisitions

OnJanuary 24, 2025, the Company acquired 100% of the membership interests of Perikard, LLC, which was accounted for as an asset acquisition consisting primarily of a single patent for pericardial access technology. The Company issued 14,473 shares of its common stock valued at $113 thousand as consideration and is obligated to make royalty payments equal to 10% of net sales of the pericardial access kit forfive years following the closing date. The patent was determined to be IPR&D withno alternative future use, and accordingly, the Company recognized $119 thousand, consisting of $113 thousand of stock consideration and $6 thousand of direct transaction costs for thesix months ended* June 30, 2025*. As of* June 30, 2026*, the Company hasnot recognized a liability for the contingent royalty payments because they are currentlynot probable or reasonably estimable.

On* December 31, 2025,in connection with thesecond* amendment of the Related Party Notes described in Note9, Notes Payable, the Company transferred the Perikard membership interests for de minimis proceeds to Mr. Jenkins. The disposal primarily related to the previously acquired patent for pericardial access technology. Because the patent was fully expensed as IPR&D at the time of acquisition and Perikard heldno other assets or liabilities,no impairment or other charges were recognized in connection with the disposal. See Note9, Notes Payable, for additional information over the debt extinguishment.

OnMay 5, 2025, Cardionomix acquired certain assets from Cardionomic. The assets primarily related to Cardionomic’s CPNS System, which represents a novel technology for the late-stage treatment of acute decompensated heart failure.

The acquisition was accounted for as an asset acquisition consisting primarily of an IPR&D Asset (the CPNS System). The Company issued 52,631 shares of its restricted common stock valued at $0.3 million, and Cardionomix issued a promissory note recorded at a carrying amount of $1.3 million (the "Note Payable"), as consideration to Cardionomic. The common stock issued hasnot been registered under the Securities Act, such that the shares* may**not* be transferred by the Seller absent an effective registration statement or an exemption from registration. Furthermore, the common stock couldnot be transferred forsix months after the closing date, after which Cardionomic* mayonly transfer the common stock to permitted transferees with the express written consent of the Company, which shallnot* be unreasonably withheld. The IPR&D Asset was determined to haveno alternative future use, and accordingly, the Company expensed the costs of acquisition of $1.9 million, consisting of $0.3 million in stock consideration, $1.3 million of promissory note, and $0.3 million in direct transaction costs, as acquired research and development expenses in the consolidated statement of operations for the year ended* December 31, 2025.*

See Note9, Notes Payable for additional information on the Note Payable.

Note17. Income Taxes

The provision for income taxes for interim periods is determined using an estimated annual effective tax rate. The effective tax rate* maybe subject to fluctuations during the year as new information is obtained, which may*affect the assumptions used to estimate the annual effective tax rate, including factors such as valuation allowances against deferred tax assets, the recognition or de-recognition of tax benefits related to uncertain tax positions, if any, and changes in or the interpretation of tax laws in jurisdictions where the Company conducts business.

For thethree andsix months ended* June 30, 2026*, the Company recorded federal income tax benefit of $0.3 million and $0.5 million, respectively, andno state income tax provision or benefit. For thethree andsix months ended* June 30, 2025,the Company recorded federal income tax benefit of $1.0 million and $1.7 million, respectively, andno* state income tax provision or benefit. The federal income tax benefit primarily relates to an increase in net operation losses that arenot subject to limitations under Section382 of the Internal Revenue Code. The Company’s net deferred tax assets generated mainly from net operating losses are fully offset by a valuation allowance as the Company believes it isnot more likely thannot that the benefit will be realized. The Company will continue to assess its position in future periods to determine if it is appropriate to reduce a portion of its valuation allowance in the future.

The Company hasno open income tax audits with any taxing authority as of* June 30, 2026*.

Note18. Commitments and Contingencies

In the normal course of business, the Company is at times subject to pending and threatened legal actions. In management’s opinion, any potential loss resulting from the resolution of these matters willnot have a material effect on the results of operations, financial position or cash flows of the Company.

Employment Litigation

In connection with the FLYTE acquisition, the Company assumed certain cont ingent liabilities, including an employment dispute with a former FLYTE employee alleging wrongful termination. The matter is currently proceeding through arbitration. While the Company disputes these allegations, the Company determined a loss was probable and reasonably estimable and recorded an estimated liability of $0.2 million under accrued expenses in the condensed consolidated balance sheets as of* June 30, 2026.No amounts have been paid related to this matter as of June 30, 2026.*

Promissory Note Settlement

On* March 9, 2026,Flyte entered into a settlement and judgment satisfaction agreement pursuant to which Flyte agreed to pay an aggregate settlement amount of $0.3 million intwo* installments of $150 thousand each. Thefirst installment was paid during thethree months ended* March 31, 2026,and the remaining $150 thousand installment was paid during thethree* months ended* June 30, 2026.As of June 30, 2026,*the settlement had been paid in full and the Company hadno remaining obligation related to the matter.
