NOTE A—DESCRIPTION OF BUSINESS Tenax Therapeutics, Inc. (the “Company”) 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, 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 (as amended, the “License”), 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, providing global rights to oral and subcutaneous formulations of levosimendan used in the treatment of 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 negotiation 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–F - 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 ( the “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 PAH (“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 (the “Merger”). Going Concern Management believes the accompanying 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 $297,252,753 and $289,542,080 on December 31, 2023 and 2022, respectively, and used cash in operations of $5,903,532 and $11,388,571 during the years ended December 31, 2023 and 2022, respectively. The Company requires substantial additional funds to complete clinical trials and pursue regulatory approvals. Management is actively seeking additional sources of equity and/or debt financing; however, there is no assurance that any additional funding will be available. In view of the matters described above, recoverability of a major portion of the recorded asset amounts shown in the accompanying December 31, 2023 balance sheet is dependent upon continued operations of the Company, which in turn is dependent upon the Company’s ability to meet its financing requirements on a continuing basis, to maintain present financing, and to generate cash from future operations. These factors, among others, raise substantial doubt about the Company’s ability to continue as a going concern. The financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or amounts and classification of liabilities that might be necessary should the Company be unable to continue in existence.

NOTE B—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Use of Estimates The preparation of the accompanying 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 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 consolidated financial statements include the accounts and transactions of Tenax Therapeutics, Inc., Life Newco, Inc. and PHPrecisionMed Inc. 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 have 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 $2,383,498 and $1,877,589 uninsured by the FDIC as of December 31, 2023 and 2022, respectively. 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 $11.7 million and $3.2 million and working capital of $8.1 million and $1.4 million as of December 31, 2023 and 2022, respectively. The Company’s cash resources were approximately $9.8 million as of December 31, 2023, compared to cash resources of approximately $2.1 million as of December 31, 2022. The Company expects to continue to incur expenses related to the development of levosimendan for pulmonary hypertension 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 December 31, 2023, the Company believes that it has sufficient capital to fund its planned operations through 2024. However, the Company will need substantial additional financing in order to fund its operations beyond such period and thereafter until it can achieve profitability, if ever. The Company depends on its ability to raise additional funds through various potential sources, such as equity and debt financing, or to license its product candidates to another pharmaceutical company. The Company will continue to fund operations from cash on hand and through sources of capital similar to those previously described. The Company cannot provide assurance that it will be able to secure such additional financing, or if available, that it will be sufficient to meet its needs. 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 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.Preclinical Study and Clinical Accruals The Company estimates its preclinical study and clinical trial expenses based on the services received pursuant to contracts with several research institutions and contract research organizations (“CROs”) that do or may conduct and manage preclinical and clinical trials on its behalf. The financial terms of the agreements vary from contract to contract, may be estimated by Tenax Therapeutics and outside advisors prior to contracting with a CRO, and may result in uneven expenses and payment flows. Preclinical study and clinical trial expenses include the following: <table cellpadding="0" style="border-spacing:0;font-size:10pt;width:100%"><tbody><tr style="height:15px"><td style="width:4%;vertical-align:top;">-</td><td style="vertical-align:top;">fees paid to CROs in connection with clinical trials,</td></tr><tr style="height:15px"><td style="vertical-align:top;">-</td><td style="vertical-align:top;">fees paid to research institutions in conjunction with preclinical and clinical research studies, and</td></tr><tr style="height:15px"><td style="vertical-align:top;">-</td><td style="vertical-align:top;">fees paid to contract manufacturers and service providers in connection with the production and testing of active pharmaceutical ingredients and drug materials for use in preclinical studies and clinical trials.</td></tr></tbody></table> Property and Equipment, Net Property and equipment are stated at cost, subject to adjustments for impairment, less accumulated depreciation and amortization. Depreciation and amortization are computed using the straight-line method with estimated useful lives of three to seven years. Maintenance and repairs are expensed as incurred, and improvements to leased facilities and equipment are capitalized. Research and Development Costs Research and development costs include, but are not limited to, (i) expenses incurred under agreements with CROs and investigative sites, which conduct our clinical trials; (ii) the cost of supplying clinical trial materials; (iii) payments to contract service organizations, as well as consultants; (iv) employee-related expenses, which include salaries and benefits; and (v) depreciation and other allocated expenses, which include direct and allocated expenses for equipment, laboratory and other supplies. All research and development expenses are expensed as incurred. Income Taxes Deferred tax assets and liabilities are recorded for differences between the financial statement and tax bases of the assets and liabilities that will result in taxable or deductible amounts in the future based on enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. Income tax expense is recorded for the amount of income tax payable or refundable for the period increased or decreased by the change in deferred tax assets and liabilities during the period. Stock-Based Compensation The Company accounts for stock-based awards to employees in accordance with 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. The Company accounts for equity instruments issued to non-employees in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Board (“ASC”) 505-50, Equity-Based Payments to Non-Employees. The Company records equity instruments at their fair value on the measurement date and periodically adjust them as the underlying equity instruments vest. 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. <table cellpadding="0" style="border-spacing:0;text-align:left;font:10pt times new roman;width:100%"><tbody><tr style="height:15px"><td> </td><td style="white-space: nowrap;"> </td><td class="hdcell" colspan="6" style="BORDER-BOTTOM: 1px solid;width:9%;vertical-align:bottom;text-align:center;">Year ended December 31,</td><td style="white-space: nowrap;"> </td></tr><tr style="height:15px"><td> </td><td style="white-space: nowrap;"> </td><td class="hdcell" colspan="2" style="BORDER-BOTTOM: 1px solid;width:9%;vertical-align:bottom;text-align:center;">2023</td><td style="PADDING-BOTTOM: 1px;white-space: nowrap;"> </td><td style="white-space: nowrap;"> </td><td class="hdcell" colspan="2" style="BORDER-BOTTOM: 1px solid;width:9%;vertical-align:bottom;text-align:center;">2022</td><td style="PADDING-BOTTOM: 1px;white-space: nowrap;"> </td></tr><tr style="height:15px"><td> </td><td style="width:1%;white-space: nowrap;"> </td><td class="ffcell" colspan="2" style="width:9%;"> </td><td style="width:1%;white-space: nowrap;"> </td><td style="width:1%;white-space: nowrap;"> </td><td class="ffcell" colspan="2" style="width:9%;"> </td><td style="width:1%;white-space: nowrap;"> </td></tr><tr style="height:15px;background-color:#cceeff"><td style="vertical-align:top;">Warrants to purchase common stock</td><td style="width:1%;white-space: nowrap;"> </td><td style="width:1%;white-space: nowrap;"> </td><td class="ffcell" style="width:9%;vertical-align:bottom;text-align:right;">19,694</td><td style="width:1%;white-space: nowrap;"> </td><td style="width:1%;white-space: nowrap;"> </td><td style="width:1%;white-space: nowrap;"> </td><td class="ffcell" style="width:9%;vertical-align:bottom;text-align:right;">19,703</td><td style="width:1%;white-space: nowrap;"> </td></tr><tr style="height:15px;background-color:#ffffff"><td style="vertical-align:top;">Pre-funded warrants to purchase common stock</td><td style="width:1%;white-space: nowrap;"> </td><td style="width:1%;white-space: nowrap;"> </td><td class="ffcell" style="width:9%;vertical-align:bottom;text-align:right;">-</td><td style="width:1%;white-space: nowrap;"> </td><td style="width:1%;white-space: nowrap;"> </td><td style="width:1%;white-space: nowrap;"> </td><td class="ffcell" style="width:9%;vertical-align:bottom;text-align:right;">-</td><td style="width:1%;white-space: nowrap;"> </td></tr><tr style="height:15px;background-color:#cceeff"><td style="vertical-align:top;">Options to purchase common stock</td><td style="width:1%;white-space: nowrap;"> </td><td style="width:1%;white-space: nowrap;"> </td><td class="ffcell" style="width:9%;vertical-align:bottom;text-align:right;">936</td><td style="width:1%;white-space: nowrap;"> </td><td style="width:1%;white-space: nowrap;"> </td><td style="width:1%;white-space: nowrap;"> </td><td class="ffcell" style="width:9%;vertical-align:bottom;text-align:right;">968</td><td style="width:1%;white-space: nowrap;"> </td></tr><tr style="height:15px;background-color:#ffffff"><td style="vertical-align:top;">Convertible preferred shares outstanding</td><td style="width:1%;white-space: nowrap;"> </td><td style="width:1%;white-space: nowrap;"> </td><td class="ffcell" style="width:9%;vertical-align:bottom;text-align:right;">210</td><td style="width:1%;white-space: nowrap;"> </td><td style="width:1%;white-space: nowrap;"> </td><td style="width:1%;white-space: nowrap;"> </td><td class="ffcell" style="width:9%;vertical-align:bottom;text-align:right;">210</td><td style="width:1%;white-space: nowrap;"> </td></tr></tbody></table>Operating Leases The Company determines if an arrangement includes a lease at inception. Operating leases are included in operating lease right-of-use assets, other current liabilities, and long-term lease liabilities in the Company’s consolidated balance sheet as of December 31, 2022. Right-of-use assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease right-of-use assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. In determining the net present value of lease payments, the Company uses the incremental borrowing rate based on the information available at the lease commencement date. The operating lease right-of-use assets also include any lease payments made and exclude lease incentives. The Company’s leases may include options to extend or terminate the lease which are included in the lease term when it is reasonably certain that the Company will exercise any such option. Lease expense is recognized on a straight-line basis over the expected lease term. The Company has elected to account for leases with an initial term of 12 months or less similar to previous guidance for operating leases, under which the Company will recognize those lease payments in the consolidated statements of operations and comprehensive loss on a straight-line basis over the lease term. Recent Accounting Pronouncements In June 2016, the FASB issued an accounting standard update, ASU-2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, that amends how credit losses are measured and reported for certain financial instruments that are not accounted for at fair value through net income. This standard requires that credit losses be presented as an allowance rather than as a write-down for available-for-sale debt securities and will be effective for interim and annual reporting periods beginning January 1, 2023, with early adoption permitted. We adopted this standard on January 1, 2023. Our adoption of the new guidance did not have a significant impact on our consolidated financial statements. Fair Value The Company determines the fair value of its financial assets and liabilities in accordance with ASC 820, Fair Value Measurements. The Company’s balance sheet includes the following financial instruments: cash and cash equivalents, investments in marketable securities and short-term notes payable. The Company considers the carrying amount of its cash and cash equivalents and short-term notes payable to approximate fair value due to the short-term nature of these instruments. Accounting for fair value measurements involves a single definition of fair value, along with a conceptual framework to measure fair value, with a fair value defined as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date”. The fair value measurement hierarchy consists of three levels: <table cellpadding="0" style="border-spacing:0;font-size:10pt;width:100%"><tbody><tr style="height:15px"><td style="width:6%;vertical-align:top;">Level one</td><td style="vertical-align:top;">Quoted market prices in active markets for identical assets or liabilities;</td></tr><tr style="height:15px"><td style="vertical-align:top;">Level two</td><td style="vertical-align:top;">Inputs other than level one inputs that are either directly or indirectly observable; and</td></tr><tr style="height:15px"><td style="vertical-align:top;">Level three</td><td style="vertical-align:top;">Unobservable inputs developed using estimates and assumptions; which are developed by the reporting entity and reflect those assumptions that a market participant would use.</td></tr></tbody></table> The Company applies valuation techniques that (1) place greater reliance on observable inputs and less reliance on unobservable inputs and (2) are consistent with the market approach, the income approach and/or the cost approach, and include enhanced disclosures of fair value measurements in the Company’s consolidated financial statements. Reclassification of Prior Year Presentation Certain prior year amounts have been reclassified for consistency with the current year presentation. These reclassifications had no effect on the financial position or reported results of operations for the periods presented. An adjustment has been made to the Consolidated Statements of Cash Flows for fiscal year ended December 31, 2022, to identify the non-cash expense related to a financing arrangement for prepaid insurance and notes payable amount of $624,302. This change in classification affects previously reported cash flows from operating activities and cash flows from financing activities.

The preparation of the accompanying 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 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.

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

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 have also been adjusted proportionately to reflect the Reverse Stock Splits.

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

The Federal Deposit Insurance Corporation (the “FDIC”) insurance limits are $250,000 per depositor per insured bank. The Company had cash balances of $2,383,498 and $1,877,589 uninsured by the FDIC as of December 31, 2023 and 2022, respectively.

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 $11.7 million and $3.2 million and working capital of $8.1 million and $1.4 million as of December 31, 2023 and 2022, respectively. The Company’s cash resources were approximately $9.8 million as of December 31, 2023, compared to cash resources of approximately $2.1 million as of December 31, 2022. The Company expects to continue to incur expenses related to the development of levosimendan for pulmonary hypertension 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 December 31, 2023, the Company believes that it has sufficient capital to fund its planned operations through 2024. However, the Company will need substantial additional financing in order to fund its operations beyond such period and thereafter until it can achieve profitability, if ever. The Company depends on its ability to raise additional funds through various potential sources, such as equity and debt financing, or to license its product candidates to another pharmaceutical company. The Company will continue to fund operations from cash on hand and through sources of capital similar to those previously described. The Company cannot provide assurance that it will be able to secure such additional financing, or if available, that it will be sufficient to meet its needs. 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 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.

allocating compensation costs of each stock option over the requisite service period using the Black-Scholes Option Pricing Model to calculate the grant date fair value. The Company had no compensation expense for stock options grants for the years ended December 31, 2023 and 2022, respectively. As of December 31, 2023, there were no unrecognized compensation costs related to non-vested stock option awards under the 1999 Plan. In connection with the retirement of the Company’s former Chief Executive Officer (“CEO”), effective July 13, 2021 (the “Modification Date”), the Company modified the terms of the former CEO’s outstanding stock awards to: (1) accelerate the 1,906 unvested shares underlying his outstanding stock awards immediately as of the Modification Date and (2) extend the period during which his outstanding stock awards for an aggregate of 2,734 shares may be exercised through the earlier of the stock award’s original termination date or the five-year anniversary of the Modification Date. The Company determined that the extension of the period during which the vested shares may be exercised was a Type 1 modification pursuant to ASC 718, Compensation-Stock Compensation. However, acceleration of vesting and extension of the exercise period for the remaining Stock Awards was a Type 3 modification pursuant to ASC 718 because absent the modification terms, those Stock Awards would have been forfeited as of the former CEO’s retirement date. On the Modification Date, the Company recognized approximately $187,000 of compensation expense, which is included in General and administrative expense for the year ended December 31, 2022, with respect to these modifications. Inducement Stock Options The Company granted two employment inducement stock option awards, one for 63 shares of common stock and the other for 156 shares of common stock, to its new CEO on July 6, 2021. The employment inducement stock option for 63 shares of common stock was awarded in accordance with the employment inducement award exemption provided by Nasdaq Listing Rule 5635(c)(4) and was therefore not awarded under the Company’s stockholder approved equity plan. The option award was to vest as follows: 50% upon initiation of a Phase 3 trial for levosimendan by June 30, 2022; and 50% upon initiation of a Phase 3 trial for imatinib by June 30, 2022. The options had a 10-year term and an exercise price of $3,152.00 per share, the July 6, 2021 closing price of our common stock. As of December 31, 2022, none of the vesting milestones had been achieved and the options were subsequently cancelled. The estimated fair value of this inducement stock option award was $178,291 using a Black-Scholes option pricing model based on market prices and the following assumptions at the date of inducement option grant: risk-free interest rate of 1.37%, dividend yield of 0%, volatility factor for our common stock of 103.50% and an expected life of 10 years.The employment inducement stock option award for 156 shares of common stock also was awarded in accordance with the employment inducement award exemption provided by Nasdaq Listing Rule 5635(c)(4) and was therefore not awarded under the Company’s stockholder approved equity plan. The option award will vest as follows: 25% on the one-year anniversary of the CEO’s employment start date and an additional 25% on each of the following three anniversaries of the CEO’s employment start date, subject to continued employment. The options have a 10-year term and an exercise price of $3,152 per share, the July 6, 2021 closing price of our common stock. As of December 31, 2023, half of the vesting milestones have been achieved. The estimated fair value of this inducement stock option award was $403,180 using a Black-Scholes option pricing model based on market prices and the following assumptions at the date of inducement option grant: risk-free interest rate of 1.13%, dividend yield of 0%, volatility factor for our common stock of 99.36% and an expected life of 7 years. The Company granted an employment inducement stock option award for 156 shares of common stock to our Chief Medical Officer on January 15, 2021. This employment inducement stock option was awarded in accordance with the employment inducement award exemption provided by Nasdaq Listing Rule 5635(c)(4) and was therefore not awarded under the Company’s stockholder approved equity plan. The option award will vest as follows: 25% upon initiation of a Phase 3 trial; 25% upon database lock; 25% upon acceptance for review of an investigational NDA; and 25% upon approval. The options have a 10-year term and an exercise price of $2,848 per share, the January 15, 2021 closing price of our common stock. As of December 31, 2023, one of the vesting milestones have been achieved. The estimated fair value of the inducement stock option award granted was $402,789 using a Black-Scholes option pricing model based on market prices and the following assumptions at the date of inducement option grant: risk-free interest rate of 11%, dividend yield of 0%, volatility factor for our common stock of 103.94% and an expected life of 10 years. Inducement stock option compensation expense totaled $74,761 for the year ended December 31, 2023. As of December 31, 2023, there was $356,685 of remaining unrecognized compensation expense related to these inducement stock options.

NOTE F—COMMITMENTS AND CONTINGENCIES Operating Leases In January 2011, the Company entered into a lease (the “Lease”) with Concourse Associates, LLC (the “Landlord”) for its headquarters located at ONE Copley Parkway, Suite 490, Morrisville, North Carolina (the “Premises”). The Lease was amended in August 2015, March 2016 and April 2021 to extend the term for the 5,954 square foot rental. 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 Prior Lease described above, none of the Company’s contracts contain a lease.

The current rent is approximately $800 per month.Simdax License Agreement On November 13, 2013, the Company acquired, through its wholly-owned subsidiary, Life Newco, that certain License Agreement, dated September 20, 2013, as amended on October 9, 2020 and January 25, 2022, by and between Phyxius and Orion (as amended, the “License”), and that certain Side Letter, dated October 15, 2013 by and between Phyxius and Orion. On February 19, 2024, the Company and Orion entered into a further amendment to the license, which terms are described below under “Note I—Subsequent Events”. The License grants the Company an exclusive, sublicensable right to develop and commercialize pharmaceutical products containing levosimendan in the territory and, pursuant to the October 9, 2020 amendment, also includes two product dose forms containing levosimendan, in capsule and solid dosage form, and a subcutaneously administered product containing levosimendan, subject to specified limitations in the License. Pursuant to the License, the Company and Orion will agree to a new trademark when commercializing levosimendan in either of these forms. 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 (i.e., line extension products). Orion’s ongoing role under the License includes sublicense approval, serving as the sole source of manufacture, holding a first right to enforce intellectual property rights in the territory, and certain regulatory participation rights. Orion must notify the Company before the end of 2024 if it chooses not to exercise its right to supply oral formulations of levosimendan to the Company for commercialization in the territory. Additionally, the Company must grant back to Orion a broad non-exclusive license to any patents or clinical trial data related to the Product developed by the Company under the License. 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. Pursuant to the terms of the License, on November 13, 2013, the Company paid to Orion a non-refundable up-front payment in the amount of $1.0 million. The License also includes the following development milestones for which the Company must make non-refundable payments to Orion no later than 28 days after the occurrence of the applicable milestone event: (1) $2.0 million upon the grant of United States Food and Drug Administration approval, including all registrations, licenses, authorizations and necessary approvals, to develop and/or commercialize the Product in the United States; and (2) $1.0 million upon the grant of regulatory approval for the Product in Canada. Once commercialized, the Company is obligated to make certain non-refundable commercialization milestone payments to Orion, aggregating to up to $13.0 million, contingent upon achievement of certain cumulative net sales amounts in the territory. The Company also must pay Orion tiered royalties based on net sales of the Product in the territory made by the Company and its sublicensees. After the end of the License term, the Company must pay Orion a royalty based on net sales of the Product in the territory for as long as the Company sells the Product in the territory. As of December 31, 2023, 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. Litigation The Company is subject to litigation in the normal course of business, none of which management believes will have a material adverse effect on the Company’s consolidated financial statements.

The Lease was amended in August 2015, March 2016 and April 2021 to extend the term for the 5,954 square foot rental. Pursuant to the Amendment dated April 2021, the existing lease term was extended through June 30, 2024

allowance against net deferred tax assets due to the uncertainty that such assets will be realized. The Company periodically evaluates the recoverability of the deferred tax assets. At such time that it is determined that it is more likely than not that deferred tax assets will be realizable, the valuation allowance will be reduced. The net increase in the valuation allowance during 2023 was approximately $1.2 million.As of December 31, 2023, the Company had Federal and State net operating loss carryforwards of approximately $166.7 million and $130.8 million available to offset future federal and state taxable income, respectively. Federal net operating losses of $120.7 million begin to expire in 2024, while the remaining $46.0 million carryforward indefinitely. State net operating losses begin to expire in 2024. Utilization of the net operating loss carryforwards may be subject to an annual limitation due to the ownership percentage change limitations provided by the Internal Revenue Code of 1986, as amended, or the Code, and similar state provisions. The annual limitations may result in the expiration of the net operating losses before utilization. We have U.S. federal net operating loss carryforwards, or NOLs, which expire in various years if not utilized. Under Sections 382 and 383 of the Code, if a corporation undergoes an “ownership change,” the corporation’s ability to use its pre-change NOLs and other pre-change tax attributes, such as research tax credits, to offset its future post-change income and taxes may be limited. In general, an “ownership change” occurs if there is a cumulative change in our ownership by “5% shareholders” that exceeds 50 percentage points over a rolling three-year period. Similar rules may apply under state tax laws. We have not performed a formal study to determine whether any of our NOLs are subject to these limitations. We have recorded deferred tax assets for our NOLs and research and development credits and have recorded a full valuation allowance against these deferred tax assets. In the event that it is determined that we have in the past experienced additional ownership changes, or if we experience one or more ownership changes as a result of future transactions in our stock, then we may be further limited in our ability to use our NOLs and other tax assets to reduce taxes owed on the net taxable income that we earn in the event that we attain profitability. Any such limitations on the ability to use our NOLs and other tax assets could adversely impact our business, financial condition, and operating results in the event that we attain profitability. The Company follows the provisions of ASC Topic 740-10, “Accounting for Uncertainty in Income Taxes” which clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements and prescribes a recognition threshold and measurement process for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. This topic also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition. There were no uncertain tax positions as of December 31, 2023 and 2022. The Company files U.S. and state income tax returns with varying statutes of limitations. The tax years 2004 and forward remain open to examination due to the carryover of unused net operating losses or tax credits.
