Ainos Inc

Notes to Condensed Financial Statements

1. Description of Business

Organization and Business

Ainos, Inc. (the “Company”), incorporated in the State of Texas in 1984, is an AI-driven healthcare and technology company pioneering scent digitization, AI-powered diagnostics, and novel therapeutics. We develop VELDONA, an oral low-dose interferon therapy targeting rare diseases, autoimmune diseases, infectious diseases, and animal health. We also develop an AI Nose technology that aims to digitize scent into Smell IDs, enabling applications in robotics, smart manufacturing, and healthcare. We are advancing commercialization primarily through strategic partnerships.

We have historically involved in the research and development of therapeutics based on VELDONA. Building on our research and development on VELDONA since inception, we are commercializing a suite of VELDONA-based product candidates. Our priority pipeline includes drug candidates for treating oral warts for human immunodeficiency virus (HIV) seropositive patients, Sjögren’s syndrome, and feline chronic gingivostomatitis (FCGS), a cat oral infection.

In 2021 and 2022, we acquired certain types of intellectual property from a controlling shareholder, Ainos Inc., a Cayman Island corporation (“Ainos KY”), to expand product portfolio into AI Nose technology and POCTs aimed to provide connected, rapid, and convenient testing for a broad range of health conditions. Pivoted from the sales of COVID-19 POCT, we aim to commercialize POCTs that detect volatile organic compounds (the “VOC”) emitted by the body, powered by our AI Nose technology platform. In 2024, we licensed certain patents and patent applications from Taiwan Carbon Nano Technology Corporation (“TCNT”), a controlling shareholder, to further expand our intellectual properties on our VOC and POCT technologies.

Underwritten Public Offering

The Company’s registration statement related to its underwritten public offering (the “Offering”) was declared effective on August 8, 2022, and the Company’s common stock and warrants began trading on the Nasdaq Capital Market (the “Nasdaq”) on August 9, 2022 under the trading symbols “AIMD” and “AIMDW”, respectively.

Reverse Stock Splits

In connection with the Offering, the Company’s board of directors on April 29, 2022 and its shareholders on May 16, 2022 approved a 1-for-15 reverse stock split of the Company’s common stock that became effective on August 9, 2022. Further, to comply with Nasdaq’s minimum $1.00 per share continued listing rules, the Company filed a Certificate of Amendment to its Restated Certificate of Formation on November 27, 2023, to apply for another reverse stock split of the Company’s common stock at a ratio of 1-for-5 which was effectuated on December 14, 2023 after receiving required approvals.

The par value of $0.01 and authorized shares of the Company’s common stock remains the same and were not adjusted as a result of the reverse stock splits. All issued and outstanding common stock, restricted stock units (RSUs), outstanding convertible notes, warrants and options to purchase common stock and per share amounts contained in the financial statements have been retroactively adjusted to give effect to the reverse stock splits for all periods presented.

At The Market Offering Agreement

On May 31, 2024, the Company entered into an At The Market Offering Agreement (the “ATM Agreement”), with H.C. Wainwright & Co., LLC or the Agent, pursuant to which the Company may issue and sell, from time to time, shares of its Common Stock, depending on market demand, with the Agent acting as the sales agent or principal (the “ATM Offering”). Sales of the Common Stock may be made by any method permitted by law deemed to be an “at the market offering” as defined in Rule 415(a)(4) of the Securities Act of 1933, as amended (the “Securities Act”), including, without limitation, sales made directly on or through the Nasdaq Capital Market. The Agent will use its commercially reasonable efforts to sell the Shares requested by the Company to be sold on its behalf, consistent with the Agent’s normal trading and sales practices, under the terms and subject to the conditions set forth in the ATM Agreement. The Company has no obligation to sell any of the Shares. The Company may instruct the Agent not to sell the Shares if the sales cannot be effected at or above the price designated by the Company from time to time and the Company may at any time suspend sales pursuant to the ATM Agreement.

The Company will pay the Agent placement fee of 3.0% of the gross sales price of the Shares sold by the Agent under the ATM Agreement. The Company has also agreed to reimburse the Agent for the fees and disbursements of its counsel, payable upon execution of the Sales Agreement, in an amount not to exceed $35,000 in addition to certain ongoing disbursements of its legal counsel up to $2,500 per calendar quarter. In addition, the Company has agreed to provide customary indemnification rights to the Agent.

The aggregate market value of Shares eligible for sale in the ATM Offering and under the ATM Agreement will be subject to the limitations of General Instruction I.B.6 of Form S-3, to the extent required under such instruction. The prospectus supplement filed with the SEC on July 11, 2024, is offering Shares having an aggregate offering price of $1,840,350.

The Company intends to use the net proceeds from the offering to fund the continued development of its product candidate and for general corporate purposes and working capital. The precise amount and timing of the application of these proceeds will depend upon a number of factors, such as the timing and progress of our research and development efforts, our funding requirements and the availability and costs of other funds.

As of March 31, 2025, the Company sold an aggregate of 29,407 shares of the Company’s common stock under the ATM facility, and received $14,605 in net proceeds, after deducting commissions and expenses.

2. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying condensed financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (the “GAAP”) and pursuant to the accounting disclosure rules and regulations of the Securities and Exchange Commission (the “SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed financial statements should be read in conjunction with the financial statements and notes included in the Company’s audited financial statements as of and for the year ended December 31, 2024 contained in the Annual Report on Form 10-K filed with the SEC on March 7, 2025.

In the opinion of management, the accompanying condensed financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, and cash flows for the interim periods. The results for the three months ended March 31, 2025 are not necessarily indicative of the results to be expected for any subsequent quarter, the year ending December 31, 2025, or any other period.

There have been no material changes to the Company’s significant accounting policies as described in the audited financial statements as of December 31, 2024.

Use of Estimates

The preparation of condensed financial statements in conformity with GAAP requires management to make certain estimates, judgments, and assumptions that affect the reported amounts of assets and liabilities and disclosures as of the date of the condensed financial statements and the reported amounts of revenues and expenses during the reporting period. The Company bases its estimates on various factors, including historical experience, and on various other assumptions that are believed to be reasonable under the circumstances, when these carrying values are not readily available from other sources. Significant items subject to estimates and assumptions include useful lives of property and equipment, valuation of stock option, warrants and convertible notes measured at fair value, and impairment testing of intangible assets. Actual results may differ from these estimates.

Liquidity

As of March 31, 2025, the Company had cash and cash equivalents of $2,628,286. The Company plans to finance its operations and development needs with its existing cash and cash equivalents, additional equity and/or debt financing arrangements. There can be no assurance that the Company will be able to obtain additional financing on terms acceptable to the Company, on a timely basis, or at all. If the Company is not able to obtain sufficient funds on acceptable terms when needed, the Company’s business, results of operations, and financial condition could be materially adversely impacted.

On May 31, 2024, the Company entered into an At The Market Offering Agreement, or sales agreement, with H.C. Wainwright & Co., LLC or Wainwright, pursuant to which the Company may issue and sell, from time to time, shares of its common stock, the aggregate market value of Shares eligible for sale in the Offering and under the ATM Agreement will be subject to the limitations of General Instruction I.B.6 of Form S-3, to the extent required under such instruction. The prospectus supplement filed with the SEC on July 11, 2024, is offering Shares having an aggregate offering price of $1,840,350. As of March 31, 2025, the Company sold 29,407 shares of common stock under At The Market Offering Agreement, resulting in net proceeds of approximately $14,605.

For the three months ended March 31, 2025, the Company generated a net loss of $3,286,022. The Company expects to continue incurring development expenses for the next twelve months as the Company advances our product development plans.

The financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The Company has incurred net operating losses since inception and has an accumulated deficit as of March 31, 2025 of $56,035,338 and expects to incur additional losses and negative operating cash flows for at least the next twelve months. The Company’s ability to meet its obligations is dependent upon its ability to generate sufficient cash flows from operations and future financing transactions. Although management expects the Company will continue as a going concern, there is no assurance that management’s plans will be successful since the availability and amount of such funding is not certain. Accordingly, substantial doubt exists about the Company’s ability to continue as a going concern for at least one year from the issuance of these financial statements. The accompanying financial statements do not include any adjustments to reflect the possible future effects on the recoverability of assets or the amounts and classifications of liabilities that may result from the possible inability of the Company to continue as a going concern.

Segments

Operating segments are defined as components of an entity for which separate financial information is available and that is regularly reviewed by the chief operating decision maker (the “CODM”) in deciding how to allocate resources to an individual segment and in assessing performance. The Company’s Chief Executive Officer is the Company’s CODM. The CODM reviews financial information prepared on the basis of accounting policy disclosed in its annual financial statement for purposes of making operating decisions, allocating resources, and evaluating financial performance of the Company. As such, the Company has determined that it operates asone operating segment.

Impairment of Intangible Assets

The Company reviews its definite-lived intangibles and other long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be fully recoverable. When such events occur, management determines whether there has been impairment by comparing the anticipated undiscounted future net cash flows to the carrying value of the asset or asset group. If impairment exists, the assets are written down to their estimated fair value. No impairment of definite-lived intangible and long-lived assets was recorded for the three months ended March 31, 2025 and 2024.

Fair Value Option

ASC 825-10,Financial Instruments, provides a fair value option (the “FVO”) election that allows companies an irrevocable election to use fair value as the initial and subsequent accounting measurement attribute for certain financial assets and liabilities. ASC 825-10 permits entities to elect to measure eligible financial assets and liabilities at fair value on an ongoing basis. Unrealized gains and losses on items for which the FVO has been elected are reported in earnings, except for the effect of changes in own credit, which are recognized in other comprehensive income/loss. The decision to elect the FVO is determined on an instrument-by-instrument basis, must be applied to an entire instrument and is irrevocable once elected. Assets and liabilities measured at fair value pursuant to ASC 825-10 are required to be reported separately from those instruments measured using another accounting method.

Recent Accounting Pronouncements Adopted

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. ASU 2023-07, which is applicable to entities with a single reportable segment, will primarily require enhanced disclosures about significant segment expenses and enhanced disclosures in interim periods. The guidance in ASU 2023-07 will be applied retrospectively and is effective for annual reporting periods in fiscal years beginning after December 15, 2023 and interim reporting periods in fiscal years beginning after December 31, 2024, with early adoption permitted. The Company does not expect the adoption of this standard to have a material impact on the Company’s unaudited condensed financial statements.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. ASU 2023-09 is intended to improve income tax disclosure requirements by requiring (1) consistent categories and greater disaggregation of information in the rate reconciliation and (2) the disaggregation of income taxes paid by jurisdiction. The guidance makes several other changes to the income tax disclosure requirements. The guidance in ASU 2023-09 will be effective for annual reporting periods in fiscal years beginning after December 15, 2024. The Company does not expect the adoption of this standard to have a material impact on the Company’s unaudited condensed financial statements.

Accounting Standards Issued but Not Yet Adopted

In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which is intended to provide more detailed information about specified categories of expenses (purchases of inventory, employee compensation, depreciation and amortization) included in certain expense captions presented on the statement of operations. The guidance in this ASU is effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted. The amendments may be applied either (1) prospectively to financial statements issued for periods after the effective date of this ASU or (2) retrospectively to all prior periods presented in the financial statements. The Company is currently evaluating the impact that the adoption of ASU 2024-03 will have on its financial statements and disclosures.

As of March 31, 2025 and December 31, 2024, cash and cash equivalents consisted of cash on hand and cash in bank which is potentially subject to concentration of credit risk. Such balance is maintained at financial institutions that management determines to be of high-credit quality.

At times, such deposits may be in excess of the insurance limit. Accounts are guaranteed by the Federal Deposit Insurance Corporation (FDIC) up to $250,000. As of March 31, 2025 and December 31, 2024, the Company had approximately $226,600 and $212,400 in excess of FDIC insured limits, respectively. The Company maintains cash in state-owned banks in Taiwan. In Taiwan, the insurance coverage of each bank is NTD$3,000,000 (approximately USD$90,350). As of March 31, 2025 and December 31, 2024, the Company had $2,025,800 and $3,311,000 cash in excess of the insured amount, respectively. The Company has not experienced any losses in such accounts.

6. Stockholders’ Equity

Preferred Stock

The Company increased authorized shares of preferred stock from 10,000,000 shares to 50,000,000 shares upon the filing of an amendment to the Company’s Certificate of Formation with the Secretary of State of Texas on November 27, 2023. No shares of preferred stock were issued and outstanding as of March 31, 2025 and December 31, 2024.

Common Stock

During the three months ended March 31, 2025, the Company issued an additional 1,787,779 shares of common stock as a result of delivering 5,872 shares to settle vested RSUs,1,752,500 shares to settle for Special Stock Award,29,407 shares to settle for ATM transaction. As of March 31, 2025, there were 17,215,164 shares of common stock legally issued and outstanding.

Warrants

As of March 31, 2025 and December 31, 2024, warrants issued and outstanding in connection with financing are summarized as below:

The Company issued the Lind Warrants on September 28, 2023 in connection with the private placement of the Lind Note. The Company further issued 20,666 shares of warrants with an exercise price of $8.25 per share to the placement agent as the agent fee. Each warrant has a contractual term of 5 years and can be exercised for the purchase of one share of common stock of the Company. The carrying amount of the Lind Warrant is nil after allocating proceeds to the Lind Note measured at fair value. The fair value of the placement agent warrant is estimated as $21,479 using the Black-Scholes Model.

As disclosed in Note 1, the Company issued public warrants together with common stock in connection with its underwritten public offering effective August 8, 2022. The Company further issued private warrants to Maxim Group LLC, as representative of the underwriter pursuant to an underwriting agreement. Each warrant has a contractual term of 5 years, expiring on August 8, 2027, and can be exercised for the purchase of one share of common stock of the Company.

The Company accounts for warrants as either equity-classified or liability-classified instruments based on an assessment of the instruments’ specific terms and applicable authoritative guidance in ASC 480,Distinguishing Liabilities from Equity (the “ASC480), and ASC 815,Derivatives and Hedging (the “ASC 815”). The assessment considers whether the instruments are free standing financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the instruments meet all of the requirements for equity classification under ASC 815, including whether the instruments are indexed to the Company’s own common shares and whether the instrument holders could potentially require “net cash settlement” in a circumstance outside of the Company’s control, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance and as of each subsequent period end date while the instruments are outstanding. Management has concluded that the warrants issued in connection with the underwritten public offering and the private placement of Lind Note qualify for equity accounting treatment and are recorded as additional paid-in capital.

In addition, the warrant issued by the Company to i2China in 2020 in exchange for consulting services is accounted for under ASC 718,Compensation – Stock Compensation (see Note 8).

As of March 31, 2025, none of the warrants have been exercised nor have expired.

Variable consideration

We record revenue from customers in an amount that reflects the transaction price we expect to be entitled to after transferring control of those goods. From time to time, we offer product sales promotions such as discounts.
