1. Formation and Business of the Company

Tivic Health Systems, Inc. (the “Company”) was incorporated in the state of California on September 22, 2016 for the purpose of developing and commercializing non-invasive bioelectronic medicine. In June 2021, the Company was reincorporated as a Delaware corporation. The Company’s first commercial product is a handheld design that interfaces non-invasively with the trigeminal, sympathetic, and other facial and cranial nerve structures, currently marketed with FDA approval as ClearUP Sinus Pain Relief, for the treatment of sinus pain and congestion. The Company is developing a research-stage platform directed to vagus nerve stimulation, which is currently undergoing clinical evaluation and optimization. In February 2025, the Company acquired a worldwide exclusive license from Statera Biopharma, Inc. ("Statera") to the late-stage TLR5 agonist Entolimod™ for the treatment of Acute Radiation Syndrome ("ARS"). In addition, the Company acquired an exclusive option to license five additional indications and clinical use cases for Entolimod and its derivative, Entolasta. In March 2025, the Company exercised its option to license Entolimod for the treatment of neutropenia. With the introduction into the biopharma market in early 2025 through the licenses acquired from Statera, the Company is a diversified therapeutics company harnessing the power of the immune and autonomic nervous systems to fight disease and restore health. The Company is headquartered in Fremont, California.

2. Summary of Significant Accounting Policies

The accompanying condensed balance sheet as of December 31, 2024, which has been derived from audited financial statements, and the unaudited interim condensed financial statements as of March 31, 2025, and for the three months ended March 31, 2025 and March 31, 2024, have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information. Certain information and note disclosures normally included in annual financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to those rules and regulations. In the opinion of management, all accounting entries and adjustments (including normal, recurring adjustments) considered necessary for a fair presentation of the financial position and the results of operations for the interim periods have been made. Operating results for the three months ended March 31, 2025 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2025.

Trade accounts receivable are recorded at the invoiced amount, net of allowances for credit losses. The allowance for credit losses is based on our assessment of the collectability of accounts. Management regularly reviews the adequacy of the allowance for credit losses by considering the age of each outstanding invoice, each customer’s expected ability to pay, and the collection history with each customer, when applicable, to determine whether a specific allowance is appropriate. Accounts receivable deemed uncollectible are charged against the allowance for credit losses when identified. As of each March 31, 2025 and December 31, 2024, the allowance for credit losses was zero.

The Company complies with the requirements of Financial Accounting Standards Board (“FASB”) Accounting Standard Codification (“ASC”) 340-10-S99-1. The Company capitalizes incremental legal, professional, accounting, and other third-party fees that are directly associated with an equity or debt offering. As of March 31, 2025, the balance of deferred offering costs is $170 thousand and consists of legal and accounting fees paid in connection with the filing of Form 1-A in August 2024 and the Equity Line of Credit discussed further in Note 10, below. If the Company consummates an equity offering, the deferred financing costs will be allocated to additional paid-in capital. If the Company consummates a debt offering, the deferred financing costs will be recorded as a discount to the debt. The costs relating to the Equity Line of Credit are reclassified to additional paid in capital on a pro-rata basis when the Company completes offerings under the Equity Line of Credit.

3. Financial Instruments and Fair Value Measurements

Cash equivalents – Cash equivalents of $0.4 million as of March 31, 2025 and $1.8 million as of December 31, 2024, consisted of money market funds. Money market funds are classified as Level 1 of the fair value hierarchy because they are valued using quoted market prices in active markets.

Certain assets and liabilities are carried at fair value under GAAP. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs.

There have been no changes to the valuation methodologies utilized by the Company during the three months ended March 31, 2025 compared to the year ended December 31, 2024. The Company evaluates transfers between levels at the end of each reporting period. There were no transfers of financial instruments between levels during the three months ended March 31, 2025 and the year ended December 31, 2024.

4. Inventory, net (in thousands)

Depreciation expense was $1 thousand for each of the three month periods ended March 31, 2025 and 2024, respectively.

6. Statera License Agreement

On February 11, 2025, the Company entered into an exclusive license agreement (the “License Agreement”) with Statera Biopharma, Inc. ("Statera"), whereby the Company acquired (i) an exclusive worldwide license to the patented Toll-like Receptor 5 (“TLR5”) agonist lead program of Statera known as Entolimod (the “Licensed Molecules”) as it relates to the Acute Radiation Syndrome (“ARS”) indication (the “Initial Indication”) and (ii) an exclusive option (the “Exclusive Option”) to acquire the exclusive worldwide license to additional indications, including lymphocyte exhaustion, immunosenescence, neutropenia and/or for use as a vaccine adjuvant (the “Subsequent Indications”) and to the TLR5 agonist follow-on program of Statera known as Entolasta.

Under the terms of the License Agreement, Statera has granted the Company an exclusive worldwide license, with the right to grant and authorize sublicenses, under Statera’s patents, trademarks, know-how and other intellectual property, to develop, test, make, have made, use, sell, offer for sale, import and otherwise exploit Entolimod as it relates to the Initial Indication during the term of the License Agreement.

As consideration for the License Agreement, the Company agreed to pay Statera a license fee of $1.5 million, consisting of (i) $300 thousand in cash consideration and (ii) $1.2 million in stock consideration, as discussed further in Notes 9 and 10 below. The Company remains liable to Statera for certain royalty payments on net sales for the ARS indication as a single agent, and, if it exercises the Exclusive Option with respect to any Subsequent Indication, net sales for such Subsequent Indications, within certain royalty periods.

The License Agreement further provides the Company with the Exclusive Option to expand the Initial Indications to include the treatment of the Subsequent Indications or to expand the use from a single agent to include uses as vaccine adjuvant, or several or all of them, at any time during the term of the License Agreement, and on one or more occasions, at its discretion. As part of exercise of the Exclusive Option, the license grant would be expanded to include uses of Entolasta, in addition to Entolimod, both for ARS and for the Subsequent Indications for which the Company has exercised its Exclusive Option.

In conjunction with the License Agreement, Statera additionally transferred to the Company the title to fifteen kilograms (15kg) of frozen manufactured Entolimod drug substance and drug product lots and associated quality records associated with their production and applicable verification records (the “Materials”). In connection with this acquisition of ownership of the Materials, the Company will be negotiating a $1 per year lease with an affiliate of Statera for the proper care, storage and handling of the Materials. The Company determined that the fair value associated with the Entolimod lots and associated lease was not material to the transaction.

The License Agreement also includes a buyout provision (the “Buyout”) by which the Company maintains the right to acquire from Statera at any time all right, title and interest in and to all technology licensed or otherwise subject to the Exclusive Option under the License Agreement. Should the Company elect to invoke this buyout right, it must provide Statera with a buyout payment equal to (a) the lesser of (i) the aggregate amount of payments due to Statera for achievement of all milestone events (described below), less the amount of payments paid for the achievement of one or more of such milestone events, and (ii) an amount negotiated in good faith and mutually agreed by the parties in writing as representing the risk adjusted net present value of the aggregate royalties that would have been payable absent such exercise; less (b) the amount of payments paid or payable by the Company to extinguish an existing lien on the licensed technology.

The Company makes certain judgments to determine whether transactions should be accounted for as acquisitions of assets or as business combinations. If it is determined that substantially all of the fair value of gross assets acquired in a transaction is concentrated in a single asset (or a group of similar assets), the transaction is treated as an acquisition of assets. The Company evaluates the inputs, processes, and outputs associated with the acquired set of activities and assets. If the assets in a transaction include an input and a substantive process that together significantly contribute to the ability to create outputs, the transaction is treated as an acquisition of a business. The Company's assessments concluded that the transactions pursuant to the Statera License Agreement constitute an asset acquisition.

The Company determined the acquisition constituted an acquisition of assets instead of a business combination as substantially all of the fair value of the gross assets acquired was concentrated in a group of similar identifiable assets, and therefore, the acquisition was not considered a business. In transactions accounted for as acquisitions of assets, no goodwill is recorded and contingent consideration, such as payments upon achievement of various developmental, regulatory and commercial milestones, generally is not recognized at the acquisition date. In an asset acquisition, up front payments allocated to in-process research and development ("IPRD") projects at the acquisition date are expensed unless there is an alternative future use. In addition, product development milestones are expensed upon achievement. As the Company is recording the transaction as an asset acquisition under ASC 805, the contingent payments will be recognized upon achievement and at that time will be expensed to in-process research and development, or capitalized, depending on the determination if there is alternative future use of the purchase. Transaction costs of approximately $226 thousand associated with the acquisition were capitalized as part of the acquisition.

The License Agreement obligates the Company to develop and commercialize the licensed products, at its own cost and expense, inclusive of licensed products with respect to any Subsequent Indications obtained upon exercise of an Exclusive Option. In the development and commercialization process, the Company is obligated to meet certain milestones, and must provide Statera with certain milestone payments, payable in either the form of cash or Company stock (at the sole discretion of the Company), upon accomplishing each milestone as outlined below.

Pursuant to the License Agreement, in the event that the Company exercises its Exclusive Option with respect to one or more Subsequent Indications, the Company may elect, in its sole discretion, to accelerate any of the milestone payments in advance of the milestone achievements.

On March 28, 2025, the Company notified Statera of its election to exercise its Exclusive Option to acquire the exclusive worldwide license to the neutropenia indication for Entolimod under the License Agreement (the “Neutropenia Option”) and to accelerate the first milestone payment of $500 thousand related to the neutropenia indication, payable by the Company in connection with the filing of an IND and initiation of a Phase 2 clinical study for neutropenia. The payment of $500 thousand was paid in Company stock, as discussed further in Notes 9 and 10 below, and was capitalized as licensed technology.

As a result of the Company’s exercise of the Neutropenia Option, the Company is obligated to develop and commercialize the expanded licensed products related to the neutropenia indication, at its own cost and expense, including to meet those milestones discussed above, and is obligated to pay the milestone payments, other than the Neutropenia Option, upon accomplishing each such milestone.

7. Commitments and Contingencies

Lease

In June 2024, the Company entered into a short-term rental agreement for office space located in Fremont, California. The Company evaluated the agreement and determined the short-term rental agreement does not meet the criteria for capitalization. Monthly rent payments required are $1 thousand per month and the agreement terminated on December 1, 2024. After expiration of the initial term, the agreement automatically renewed on a month to month basis and continues until terminated by either party upon 30 days' advance written notice.

The Company has entered into multiple contracts related to the development of Tivic's ncVNS technology, including a collaboration and research support agreement and a research study to substantiate clinical indications that have potential to be addressed by Tivic's patent-pending ncVNS system. The contracts require milestone payments to be made upon the successful completion of certain deliverables. As of March 31, 2025, the Company has remaining commitments to pay a total of $86 thousand for milestones not yet achieved. The remaining payments are expected to be incurred over the next two months.

From time to time, the Company may have certain contingent liabilities that arise in the ordinary course of its business activities. The Company accrues a liability for such matters when future expenditures are probable and such expenditures can be reasonably estimated. The Company recorded no liabilities for contingent matters as of March 31, 2025.

Effective March 7, 2025, the Company implemented a reverse stock split of its issued and outstanding shares of common stock, par value $0.0001 per share, at a ratio of 1-for-17. As a result of the reverse stock split, the total number of shares of common stock held by each stockholder of the Company were converted automatically into the number of shares of common stock equal to the number of issued and outstanding shares of common stock held by each such stockholder immediately prior to the reverse stock split divided by 17. The Company issued one whole share of the post reverse stock split common stock to any stockholder who otherwise would have been entitled to receive a fractional share as a result of the reverse stock split (for a total of 76 shares). As a result, no fractional shares were issued in connection with the reverse stock split and no cash or other consideration was paid in connection with any fractional shares that would otherwise have resulted from the reverse stock split. Also, all options, warrants and other convertible securities of the Company outstanding immediately prior to the reverse stock split were adjusted by dividing the number of shares of common stock into which such options, warrants and other convertible securities were exercisable or convertible by 17 and multiplying the exercise or conversion price thereof by 17, all in accordance with the terms of the plans, agreements or arrangements governing such options, warrants and other convertible securities and subject to rounding pursuant to such terms.

Stock Options

In the case of an incentive stock option (i) granted to an employee who, at the time of grant of such option, owns stock representing more than 10% of the voting power of all classes of stock of the Company or any parent or subsidiary of the Company, the exercise price shall be no less than 110% of the fair market value per share on the date of grant; (ii) granted to any other employee, the per share exercise price shall be no less than 100% of the fair market value per share on the date of grant. In the case of a non-statutory stock option (i) granted to an employee who, at the time of grant of such option, owns stock representing more than 10% of the voting power of all classes of stock of the Company or any parent or subsidiary of the Company, the exercise price shall be no less than 110% of the fair market value per share on the date of grant; (ii) granted to any other service provider, the per share exercise price shall be no less than 100% of the fair market value per share on the date of grant.

The options may include provisions permitting exercise of the option prior to full vesting. Any unvested shares upon termination shall be subject to repurchase by the Company at the original exercise price of the option. Stock options granted under the Company’s equity incentive plans generally vest over four years from the date of grant.

The weighted average remaining contractual life as of March 31, 2025 for stock options outstanding and stock options exercisable was 8.96 and 8.71 years, respectively. Stock-based compensation expense related to stock options was $74 thousand and $52 thousand for the three months ended March 31, 2025 and 2024, respectively.

13. Net Loss per Share

The Company applies the two-class method in calculating the net loss per share amounts which requires net loss to be allocated between the common and convertible preferred stockholders based on their respective right to receive dividends. Accordingly, the Company’s basic net loss per share attributable to common stockholders is calculated by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period. Net loss attributable to common stockholders is equal to the Company’s net loss.

Basic earnings per share ("EPS") is calculated by dividing net income, less any dividends, accretion or decretion, redemption or induced conversion on our Series Preferred Stock, by the weighted average number of shares outstanding during the reported period.

In computing diluted EPS, we adjust the numerator used in the basic EPS computation, subject to anti-dilution requirements, to add back the dividends (declared or cumulative undeclared) applicable to the Series A Preferred Stock. Such add-back would also include any adjustments to equity in the period to accrete the Series A Preferred Stock to its redemption price, or recorded upon a redemption or induced conversion. We adjust the denominator used in the basic EPS computation, subject to anti-dilution requirements, to include the dilution from potential shares resulting from the issuance of the Series A Preferred Stock, restricted stock units, and stock options.

15. Subsequent Events

Preferred Purchase Agreement

On April 29, 2025, the Company entered into an Securities Purchase Agreement (the “Preferred Purchase Agreement”) with an investor (the “Investor”), pursuant to which, subject to the conditions set forth therein, the Company shall sell to the Investor, and the Investor shall purchase from the Company, up to 8,400 shares of the Company’s newly designated Series B Non-Voting Convertible Preferred Stock (“Series B Preferred”) and warrants (“Warrants”) to purchase shares of the Company’s common stock for a total purchase price of up to $8,400,000 (the “Preferred Offering”) in several tranche closings (each, a “Tranche Closing”).

The Preferred Purchase Agreement provides that the Preferred Offering shall be conducted through six separate Tranche Closings pursuant to which, subject to satisfaction of the applicable closing conditions set forth in the Preferred Purchase Agreement, the Company shall sell and issue the Investor up to an aggregate of 8,400 shares of Series B Preferred as follows: (i) 700 shares of Series B Preferred, for $700,000, in the initial Tranche Closing, which shall be consummated upon effectiveness of the Registration Statement (defined below); (ii) 700 shares of Series B Preferred, for $700,000, in the second Tranche Closing, which shall be consummated 10 trading days after the initial Tranche Closing; (iii) 1,750 shares of Series B Preferred, for $1,750,000, in the third Tranche Closing, which shall be consummated 20 trading days after the second Tranche Closing; (iv) 1,750 shares of Series B Preferred, for $1,750,000, in the fourth Tranche Closing, which shall be consummated 20 trading days after the third Tranche Closing; (v) 1,750 shares of Series B Preferred, for $1,750,000, in the fifth Tranche Closing, which shall be consummated 20 trading days after the fourth Tranche Closing; and (vi) 1,750 shares of Series B Preferred, for $1,750,000, in the final Tranche Closing, which shall be consummated 20 trading days after the fifth Tranche Closing.

In addition to the shares of Series B Preferred to be sold and issued to the Investor in the Preferred Offering, at each Tranche Closing the Company shall also issue the Investor a Warrant to purchase that number of shares of Company common stock equal to 30% of shares of common stock issuable upon conversion in full of the shares of Series B Preferred issued at the same Tranche Closing. Each Warrant shall be immediately exercisable (subject to certain beneficial ownership limitations and Stockholder Approval), expire five years from the date of issuance, and have an initial exercise price equal to the average closing price of the Company’s common stock during the prior five trading days preceding each Tranche Closing (as may be adjusted for stock dividends, subdivisions, or combinations in the manner described in the Warrant). In the event that Warrants issued to the Investor in a subsequent Tranche Closing have a lower exercise price than the Investor’s Warrants outstanding as of such later Tranche Closing, immediately after the Tranche Closing the exercise price of all outstanding Warrants held by the Investor shall automatically be reduced to equal such lower exercise price of the Warrants issued in such Tranche Closing.

In the event that the average closing price of the Company’s common stock during the prior three trading days preceding a Tranche Closing date shall not be equal to or greater than the Floor Price (as defined below), then the applicable Tranche Closing shall be delayed until such time as the price meets the required threshold for a period of five consecutive trading days. Notwithstanding the foregoing, the Investor has the ability, subject to prior written consent of the Company, to purchase any number of shares of Series B Preferred prior to the dates of the Tranche Closings provided for in the Preferred Purchase Agreement.

The Preferred Purchase Agreement contains customary termination provisions for the Investor under certain limited circumstances and the Preferred Purchase Agreement will automatically terminate if any Tranche Closing has not occurred prior to December 31, 2025.

Craft Capital Management LLC (“Craft”) acted as placement agent to the Company in connection with the Preferred Offering. As consideration for services rendered by Craft, the Company shall pay Craft a cash fee equal to eight percent (8%) of any such funds received by the Company from the Investor pursuant to the Preferred Purchase Agreement.

Designation of Series B Preferred Stock

On April 29, 2025, the Company filed a Certificate of Designation of Preferences, Rights and Limitations of the Series B Non-Voting Convertible Preferred Stock (the “Certificate of Designation”) with the Secretary of State of the State of Delaware in connection with the Preferred Offering.

The Certificate of Designation became effective upon filing and designates 8,400 shares of the Company’s preferred stock as Series B Non-Voting Convertible Preferred Stock, par value $0.0001 per share.

Ranking. The Series B Preferred ranks senior to the Company’s common stock and Series A Preferred stock with respect to dividend rights and rights on the distribution of assets on any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Company.

Dividends. The holders of outstanding shares of Series B Preferred shall be entitled to cumulative dividends at an annual rate of 10% of the Stated Value (as defined below) per share. Dividends shall accrue from the date of each such Tranche Closing, and for as long as any shares of Series B Preferred remain issued and outstanding and are payable quarterly in arrears. At the Company’s option, dividends on the Series B Preferred may be paid in (i) cash, (ii) by adding the amount of dividends payable on such date to the aggregate Stated Value of such Holder’s shares of Series B Preferred Stock (“PIK Dividends”), or (iii) any combination of cash and PIK Dividends. The “Stated Value” shall mean $1,000 per share, subject to adjustment in the event of any stock dividend (including PIK Dividends), stock split, combination, recapitalization, or other similar event affecting such shares.

Voting. Except as otherwise provided by the Certificate of Designation or required by law, the Series B Preferred does not have voting rights. However, as long as any shares of Series B Preferred are outstanding, the Company will not, without the affirmative vote of the holders of a majority of the then-outstanding shares of the Series B Preferred, (i) alter or change adversely the powers, preferences or rights given to the Series B Preferred or alter or amend the Certificate of Designation, amend or repeal any provision of, or add any provision to, the Company’s amended and restated certificate of incorporation, as amended (the “Charter”), or bylaws of the Company, or file any articles of amendment, certificate of designations, preferences, limitations and relative rights of any series of preferred stock, in each case if any such action would adversely alter or change the preferences, rights, privileges or powers of, or restrictions provided for the benefit of the Series B Preferred, (ii) issue further shares of Series B Preferred, or (iii) enter into any agreement with respect to any of the foregoing.

Conversion. Subject to certain beneficial ownership limitations and, until such date that Stockholder Approval is obtained, the Exchange Cap, at any time after the issuance date, each holder of Series B Preferred shall have the right, at such holder’s option, to convert any or all of the shares of Series B Preferred held by such holder into fully paid and nonassessable shares of Company common stock. The number of shares of common stock issuable upon conversion of each share of Series B Preferred shall be equal to the quotient obtained by dividing (i) the Stated Value of such share of Series B Preferred plus all accrued and unpaid dividends thereon by (ii) the Conversion Price (as defined below) in effect on the date of conversion. The conversion price (the “Conversion Price”) in effect on any conversion date shall be equal to 90% of the lowest closing volume-weighted average price of the Company’s common stock on the Nasdaq Capital Market for the five trading days immediately preceding the date of the conversion notice delivered by the holder, subject to adjustment, provide, however, that in no event shall the Conversion Price be lower than $1.294 per share (the “Floor Price”), subject to adjustment.

Liquidation. In the event of any liquidation, dissolution, or winding up of the Company, whether voluntary or involuntary, the holders of Series B Preferred shall be entitled to receive, prior and in preference to any distribution of any of the assets, funds, or proceeds available for distribution of the Company to the holders of Common Stock or any other class or series of capital stock ranking junior to the Series B Preferred upon liquidation, by reason of their ownership thereof, an amount per share equal to the greater of (i) the Stated Value plus all accrued and unpaid dividends thereon or (ii) the amount that such Holder would receive if such Holder converted all of its shares of Series B Preferred into common stock immediately prior to such liquidation, dissolution or winding up.

Redemption. The Company may, at any time and in its sole discretion, request to redeem all or any portion of the outstanding shares of Series B Preferred at a price equal to 115% of the Stated Value plus all accrued and unpaid dividends thereon by providing the holder at least 10 days prior written notice, during which 10 day period the holder thereof shall have the right to convert such holder’s shares of Series B Preferred into shares of Company common stock. Upon the closing of any equity or equity-linked financing by the Company after the issuance date, the holder shall have the right, but not the obligation, to require the Company to redeem, out of the proceeds of such financing, up to 25% of the aggregate amount of net proceeds raised in the financing, outstanding shares of Series B Preferred at a per share price equal to the Stated Value plus all accrued and unpaid dividends thereon, provided that such right shall expire 5 days after the holder receives notice from the Company of the consumption of a financing.
