TENAX THERAPEUTICS INC

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1. DESCRIPTION OF BUSINESS

Tenax Therapeutics, Inc. (the “Company” or “Tenax”) was originally formed as a New Jersey corporation in 1967 under the name Rudmer, David & Associates, Inc., and subsequently changed its name to Synthetic Blood International, Inc. On June 17, 2008, the stockholders of Synthetic Blood International approved the Agreement and Plan of Merger dated April 28, 2008, between Synthetic Blood International and Oxygen Biotherapeutics, Inc., a Delaware corporation. Synthetic Blood International formed Oxygen Biotherapeutics on April 17, 2008 to participate in the merger for the purpose of changing the state of domicile of Synthetic Blood International from New Jersey to Delaware. Certificates of Merger were filed with the states of New Jersey and Delaware and the merger was effective June 30, 2008. Under the Plan of Merger, Oxygen Biotherapeutics was the surviving corporation and each share of Synthetic Blood International common stock outstanding on June 30, 2008 was converted into one share of Oxygen Biotherapeutics common stock. On September 19, 2014, the Company changed its name to Tenax Therapeutics, Inc.

On November 13, 2013, the Company, through its wholly-owned subsidiary, Life Newco, Inc., a Delaware corporation (“Life NewCo”), acquired certain assets of Phyxius Pharma, Inc., a Delaware corporation (“Phyxius”) pursuant to an Asset Purchase Agreement dated October 21, 2013 (the “Asset Purchase Agreement”), by and among the Company, Life Newco, Phyxius and the stockholders of Phyxius. Among these assets was a license with Orion Corporation, a global healthcare company incorporated under the laws of Finland (“Orion”) for the exclusive, sublicensable right to develop and commercialize pharmaceutical products containing levosimendan, 2.5 mg/ml concentrate for solution for infusion / 5ml vial in the United States and Canada. On October 9, 2020 and January 25, 2022, the Company entered into an amendment to the license to include in the scope of the license two new oral product formulations containing levosimendan, in capsule and solid dosage form (TNX-103) and a subcutaneously administered dosage form (TNX-102), subject to specified limitations (together, the “Product”).

In February 2024, the Company entered into an additional amendment to the license (as amended, the “License”), providing global rights to oral and subcutaneous formulations of levosimendan used in the treatment of pulmonary hypertension in heart failure with preserved ejection fraction (“PH-HFpEF”), revising the royalty structure, lowering the royalty rates, modifying milestones associated with certain regulatory and commercial achievements, and excluding from the Company’s right of first refusal the right to commercialize new applications of levosimendan for neurological diseases and disorders developed by Orion. Pursuant to the License, the Company and Orion will agree to a new trademark when commercializing levosimendan in either of these forms. The term of the License has been extended until 10 years after the launch of the Product in the territory, provided that the License will continue after the end of the term in each country in the territory until the expiration of Orion’s patent rights in the Product in such country. In the event that no regulatory approval for the Product has been granted in the United States on or before September 20, 2030, however, either party will have the right to terminate the License with immediate effect. The Company intends to conduct two upcoming Phase 3 studies in pulmonary hypertension patients utilizing one of these oral formulations. See “Note 6 - Commitments and Contingencies” below for a further discussion of the License.

On January 15, 2021, the Company, Life Newco II, Inc., a Delaware corporation and a wholly-owned, subsidiary of the Company (“Life Newco II”), PHPrecisionMed Inc., a Delaware corporation (“PHPM”) and Dr. Stuart Rich, solely in his capacity as holders’ representative, entered into an Agreement and Plan of Merger (the “Merger Agreement”) pursuant to which the Company acquired all of the equity of PHPM, a company developing pharmaceutical products containing imatinib for the treatment of pulmonary arterial hypertension (“PAH”) in the United States and the rest of the world. Under the terms of the Merger Agreement, Life Newco II merged with and into PHPM, with PHPM surviving as a wholly-owned subsidiary of the Company.

Going Concern

Management believes the accompanying unaudited condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”), which contemplate continuation of the Company as a going concern. The Company has an accumulated deficit of approximately $308.6 million and $297.3 million on September 30, 2024, and December 31, 2023, respectively, and expects to incur substantial operating losses for the foreseeable future.

On August 8, 2024, the Company closed a private placement financing (the “August 2024 Offering”), generating gross proceeds of approximately $99.7 million, before deducting placement agent fees and estimated offering expenses payable by the Company. In assessing its ability to continue as a going concern, the Company has carefully evaluated the conditions and events that may raise substantial doubt about its ability to continue operations for one year from the issuance date of the financial statements included herein. This evaluation considered several factors, including the Company's current financial condition and available liquidity sources, which now include the proceeds from the August 2024 Offering. Additionally, the assessment incorporated the Company’s current cash and cash equivalents balances, projected cash flows, and obligations due within twelve months of the issuance date of these financial statements.

In view of the matters described above, the Company has determined that there is no longer substantial doubt about its ability to continue as agoing concern given the approximately $99.7 million in gross proceeds from the August 2024 Offering, which is believed by Company management to be sufficient for the Company to continue its operations over at least the next 12 months.

NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with GAAP for interim financial information and the instructions to Form 10‑Q and Article 10 of Regulation S-X. Accordingly, they do not include all the information and footnotes required by GAAP for complete financial statements. In the opinion of management, the unaudited condensed consolidated financial statements reflect all adjustments, which include only normal recurring adjustments necessary for the fair statement of the balances and results for the periods presented. Certain information and footnote disclosures normally included in the Company’s annual financial statements prepared in accordance with GAAP have been condensed or omitted. These condensed consolidated financial statement results are not necessarily indicative of results to be expected for the full fiscal year or any future period.

The accompanying unaudited condensed consolidated financial statements and related disclosures have been prepared with the presumption that users of the unaudited condensed consolidated financial statements have read or have access to the audited financial statements for the preceding fiscal year. Accordingly, these unaudited condensed consolidated financial statements should be read in conjunction with the Company’s Form 10-K, which was filed with the United States Securities and Exchange Commission (“SEC”) on March 28, 2024, from which the Company derived the balance sheet data on December 31, 2023.

Use of Estimates

The preparation of the accompanying unaudited condensed consolidated financial statements in conformity with GAAP requires management to make certain 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 reported amounts of expenses during the reporting period. Actual results could differ from those estimates.

On an ongoing basis, management reviews its estimates to ensure that these estimates appropriately reflect changes in the Company’s business and new information as it becomes available. If historical experience and other factors used by management to make these estimates do not reasonably reflect future activity, the Company’s results of operations and financial position could be materially impacted.

Principles of Consolidation

The accompanying unaudited condensed consolidated financial statements include the accounts and transactions of Tenax, Life Newco, Inc. and PHPM. All material intercompany transactions and balances have been eliminated in consolidation.

Reverse Stock Splits

The Company has adjusted the financial statements to reflect that on January 2, 2024, we effected a 1-for-80 reverse stock split (the “Reverse Stock Split”). The Company has also adjusted the financial statements to reflect that on January 4, 2023, we effected a 1-for-20 reverse stock split (the “Prior Reverse Stock Split”, together with the Reverse Stock Split, the “Reverse Stock Splits”). The Reverse Stock Splits did not change the number of authorized shares of capital stock or cause an adjustment to the par value of our capital stock. Pursuant to their terms, a proportionate adjustment was made to the per share exercise price and number of shares issuable under our outstanding stock options and warrants. The number of shares authorized for issuance pursuant to our equity incentive plans has also been adjusted proportionately to reflect the Reverse Stock Splits.

Cash and Cash Equivalents

The Company considers all highly liquid instruments with a maturity date of three months or less, when acquired, to be cash equivalents.

Cash Concentration Risk

The Federal Deposit Insurance Corporation (the “FDIC”) insurance limits are $250,000 per depositor per insured bank. The Company had cash balances of $495,909 and $2,383,498 uninsured by the FDIC as of September 30, 2024 and December 31, 2023, respectively. In August 2023, the Company, through its commercial bank began to utilize the IntraFi network of commercial banks. IntraFi deposits $250,000 in each of its member banks to maintain the FDIC insurance limit. On September 30, 2024, the Company had $97.6 million deposited in the network which is fully FDIC insured.

Liquidity and Capital Resources

The Company has financed its operations since September 1990 through the issuance of debt and equity securities and loans from stockholders. The Company had total current assets of approximately $99.8 million and $11.7 million and working capital of $97.2 million and $8.1 million as of September 30, 2024, and December 31, 2023, respectively.

The Company’s cash resources were approximately $98.3 million as of September 30, 2024, compared to cash resources of approximately $9.8 million as of December 31, 2023.

The Company expects to continue to incur expenses related to the development of levosimendan for PH-HFpEF and other potential indications and, over the long term, imatinib for PAH, as well as identifying and developing other potential product candidates. Based on its resources on September 30, 2024, the Company believes that it has sufficient capital to fund its planned operations through the end of 2027.

To the extent that the Company raises additional funds by issuing shares of its common stock or other securities convertible or exchangeable for shares of common stock, stockholders will experience dilution, which may be significant. In the event the Company raises additional capital through debt financings, the Company may incur significant interest expense and become subject to restrictive covenants in the related transaction documentation that may affect the manner in which the Company conducts its business. To the extent that the Company raises additional funds through collaboration and licensing arrangements, it may be necessary to relinquish some rights to its technologies or product candidates or grant licenses on terms that may not be favorable to the Company. Any or all of the foregoing may have a material adverse effect on the Company’s business and financial performance.

Stock-Based Compensation

The Company accounts for stock-based awards to employees in accordance with Accounting Standards Codification (“ASC”) 718,Compensation — Stock Compensation, which provides for the use of the fair value-based method to determine compensation for all arrangements where shares of stock or equity instruments are issued for compensation. Fair values of equity securities are determined by management based predominantly on the trading price of the Company’s common stock. The values of these awards are based upon their grant-date fair value. That cost is recognized over the period during which the employee is required to provide service in exchange for the reward.

Equity-Based Payments to Non-Employees

The Company accounts for equity instruments issued to non-employees in accordance with ASC 505-50,Equity-Based Payments to Non-Employees. Equity instruments issued to non-employees are recorded at their fair value on the measurement date and are subject to periodic adjustment as the underlying equity instruments vest.

Warrants for Common Shares and Derivative Financial Instruments

Warrants for our shares of common stock and other derivative financial instruments are classified as equity if the contracts: (i) require physical settlement or net-share settlement or (ii) give the Company a choice of net-cash settlement or settlement in its own shares (physical settlement or net-share settlement). Contracts are classified as equity or liabilities if the contracts: (i) require net-cash settlement (including a requirement to net cash settle the contract if an event occurs and if that event is outside the control of the Company), (ii) give the counterparty a choice of net-cash settlement or settlement in shares (physical settlement or net-share settlement), or (iii) contain reset provisions that do not qualify for the scope exception. The Company assesses the classification of its warrants for shares of common stock and other derivatives at each reporting date to determine whether a change in classification between equity and liabilities is required.

Loss Per Share

Basic loss per share, which excludes antidilutive securities, is computed by dividing net loss by the weighted-average number of common shares outstanding for that particular period. In contrast, diluted loss per share considers the potential dilution that could occur from other equity instruments that would increase the total number of outstanding shares of common stock. Such amounts include shares potentially issuable under outstanding options, restricted stock, and warrants.

The following outstanding options, restricted stock grants, convertible preferred shares and warrants were excluded from the computation of basic and diluted net loss per share for the periods presented because including them would have had an anti-dilutive effect.

Pursuant to the Amendment dated April 2021, the existing lease term was extended through June 30, 2024, and the annual base rent of $125,034 would increase 2.5% annually for lease years two and three. On February 7, 2023, the Company entered into a Lease Termination Agreement with the Landlord, with respect to the Premises. As consideration for the Landlord’s entry into the Lease Termination Agreement, including a release of any claims the Landlord may have had against the Company under the Lease, the Company paid the Landlord $169,867. Pursuant to the Lease Termination Agreement, effective February 8, 2023, the Company has no remaining rent or further obligations to the Landlord pursuant to the Lease.

The Company performed an evaluation of its other contracts with customers and suppliers in accordance with ASC 842,Leases, and determined that, except for the Lease described above, none of the Company’s contracts contain a lease.

The Company owns no real property.

NOTE 6. COMMITMENTS AND CONTINGENCIES

Simdax license agreement

On November 13, 2013, the Company, through its wholly-owned subsidiary, Life Newco, Inc., acquired certain assets of Phyxius pursuant to the Asset Purchase Agreement by and among the Company, Life Newco, Phyxius and the stockholders of Phyxius. Among these assets was a license with Orion for the exclusive, sublicensable right to develop and commercialize pharmaceutical products containing levosimendan, 2.5 mg/ml concentrate for solution for infusion / 5ml vial in the United States and Canada. On October 9, 2020 and January 25, 2022, the Company entered into an amendment to the license to include in the scope of the license two new oral Product formulations containing levosimendan, in capsule and solid dosage form (TNX-103) and a subcutaneously administered dosage form (TNX-102), subject to specified limitations.

On February 19, 2024, the Company entered into an additional amendment to the License providing global rights to oral and subcutaneous formulations of levosimendan used in the treatment of PH-HFpEF. The amendment also reduced the tiered royalties based on worldwide net sales of the product by the Company and its sublicensees, increased the License’s existing milestone payment due to Orion upon the grant of United States Food and Drug Administration approval of a levosimendan-based product to $10.0 million and added a milestone payment to Orion of $5.0 million due upon the grant of regulatory approval for a levosimendan-based product in Japan. The amendment also (i) increased the Company’s obligations to make certain non-refundable commercialization milestone payments to Orion, aggregating to up to $45.0 million, contingent upon achievement of certain cumulative worldwide sales of the product by the Company, and (ii) reduced the maximum price per capsule payable by the Company to Orion, under a yet-to-be-negotiated supply agreement, for the commercial supply of oral levosimendan-based product. Pursuant to the License, the Company and Orion will agree to a new trademark when commercializing levosimendan in either of the dosage forms.

The term of the License extends until 10 years after the launch of the Product in the territory, provided that the License will continue after the end of the term in each country in the territory until the expiration of Orion’s patent rights in the Product in such country. In the event that no regulatory approval for the Product has been granted in the United States on or before September 20, 2030, however, either party will have the right to terminate the License with immediate effect.

The License also grants the Company a right of first refusal to commercialize new developments of the Product, including developments as to the formulation, presentation, means of delivery, route of administration, dosage or indication but, pursuant to the February 2024 amendment, excluding new applications of levosimendan for neurological diseases and disorders developed by Orion.

As of September 30, 2024, the Company has not met any of the developmental milestones under the License and, accordingly, has not recorded any liability for the contingent payments due to Orion.

The Company has adjusted all share amounts and references to stock prices in this Quarterly Report on Form 10-Q, as well as our financial statements, to reflect the Reverse Stock Splits. The Reverse Stock Splits did not change the number of authorized shares of capital stock or cause an adjustment to the par value of our capital stock. Pursuant to their terms, a proportionate adjustment was made to the per share exercise price and number of shares issuable under our outstanding stock options and warrants. The number of shares authorized for issuance pursuant to our equity incentive plans has also been adjusted proportionately to reflect the Reverse Stock Splits.

August 2024 Private Placement Financing (the “August 2024 Offering”)

On August 6, 2024, the Company entered into a securities purchase agreement with certain accredited investors for the purchase and sale, in a private placement financing by the Company, of (i) an aggregate of 1,450,661 shares of its common stock, and pre-funded warrants to purchase an aggregate of 31,882,671 shares of common stock and (ii) accompanying warrants to purchase up to an aggregate of 16,666,666 shares of its common stock (or, in lieu thereof, additional pre-funded warrants) at a combined offering price of $3.00 per share of common stock and accompanying warrant, or $2.99 per pre-funded warrant and accompanying warrant, resulting in gross proceeds of approximately $99.7 million.

Also, on August 6, 2024 and in connection with the August 2024 Offering, the Company entered into a registration rights agreement (the “August 2024 Registration Rights Agreement”) with the purchasers, pursuant to which the Company agreed to register for resale the shares of common stock issued in the August 2024 Offering and the shares of common stock issuable upon exercise of the warrants issued in the August 2024 Offering within 60 days following the effective date of the August 2024 Registration Rights Agreement. Pursuant to the August 2024 Registration Rights Agreement, on August 30, 2024, the Company filed a resale registration statement on Form S-3 with the SEC, which went effective on September 12, 2024.

The August 2024 Registration Rights Agreement includes liquidated damages provisions that meet the definition of a registration payment arrangement that is within the scope of ASC 825-20. The Company determined at the initial issuance of the pre-funded warrants and accompanying warrant that it is not probable that a payment would be required as it has both the intent and ability to satisfy the August 2024 Registration Rights Agreement. Therefore, the Company did not record a liability at inception but will evaluate the contingency at each reporting period.
