Basis of presentation—The accompanying consolidated financial statements have been prepared in accordance with GAAP codified in the Accounting Standards Codification (“ASC”) and Accounting Standards Updates (“ASU”) of the Financial Accounting Standards Board (“FASB”).

Principles of consolidation—The consolidated financial statements include the accounts of the Company and EMI Holding, Inc. subsidiary and EMI Holding’s wholly‑owned subsidiary, Emmaus Medical Inc., and Emmaus Medical, Inc’s wholly‑owned subsidiaries. All significant intercompany transactions have been eliminated.

Estimates—Financial statements prepared in accordance with GAAP require management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates made by management include those relating to revenue recognition on product sales, the estimated useful lives of equipment, impairment of assets, inventory reserve, allowance for credit losses, implied interest rate used on operating leases, the variables used to calculate the valuation of investment in convertible bond, conversion features, stock options and warrants, and estimated accruals on an ongoing basis. The Company bases its estimates on historical experience and on various other assumptions that management believes to be reasonable under the circumstances. Actual results could differ from those estimates under different assumptions or conditions. To the extent there are material differences between these estimates and actual results, the Company’s financial statements will be affected.

Revenue recognition— The Company realizes net revenues primarily from sales of Endari® to distributors and specialty pharmacy providers. Distributors resell Endari® to other pharmacy and specialty pharmacy providers, health care

providers, hospitals, and clinics. In addition to agreements with these distributors, the Company has contractual arrangements with specialty pharmacy providers, in-office dispensing providers, physician group purchasing organizations, pharmacy benefits managers and government entities that provide for government-mandated or privately negotiated rebates, chargebacks and discounts with respect to the purchase of Endari®. These various discounts, rebates, and chargebacks are referred to as “variable consideration.” Revenue from product sales is recorded net of variable consideration.

Under ASC 606 Revenue from Contracts with Customers, the Company recognizes revenue when its customers obtain control of the Company's product, which typically occurs on delivery. Revenue is recognized in an amount that reflects the consideration that the Company expects to receive in exchange for the product, or transaction price. To determine revenue recognition for contracts with customers within the scope of ASC 606, the Company performs the following 5 steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the Company’s performance obligations in the contract; and (v) recognize revenue when (or as) the Company satisfies the relevant performance obligations.

Revenue from product sales is recorded at the transaction price, net of estimates for variable consideration consisting of sales discounts, returns, government rebates, chargebacks and commercial discounts. Variable consideration is estimated using the expected-value amount method, which is the sum of probability-weighted amounts in a range of possible transaction prices. Actual variable consideration may differ from the Company's estimates. If actual results vary from the Company's estimates, the Company adjusts the variable consideration in the period such variances become known, which would affect net revenues in that period. The following are our significant categories of variable consideration:

Sales Discounts: The Company provides its customers prompt payment discounts and from time to time offers additional discounts for bulk orders that are recorded as a reduction of revenues in the period the revenues are recognized.

Product Returns: The Company offers distributors a right to return product purchased principally based upon (i) overstocks, (ii) inactive product or non-moving product due to market conditions, and (iii) expired products. Product return allowances are estimated and recorded at the time of sale.

Government Rebates: The Company is subject to discount obligations under state Medicaid programs and the Medicare Part D prescription drug coverage gap program. Management estimates Medicaid and Medicare Part D prescription drug coverage gap rebates based upon a range of possible outcomes that are probability-weighted for the estimated payor mix. These reserves are recorded in the same period the related revenues are recognized, resulting in a reduction of product revenues and the establishment of a current liability that is included as an accounts payable and accrued expenses in the consolidated balance sheets. The liability for these rebates consists primarily of estimates of claims expected to be received in future periods related to recognized revenues.

Chargebacks and Discounts: Chargebacks for fees and discounts represent the estimated obligations resulting from contractual commitments to sell products to certain specialty pharmacy providers, in-office dispensing providers, group purchasing organizations, and government entities at prices lower than the list prices charged to distributors. The distributors charge the Company for the difference between what they pay for the products and the Company’s contracted selling price to these specialty pharmacy providers, in-office dispensing providers, group purchasing organizations, and government entities. In addition, the Company has contractual agreements with pharmacy benefit managers who charge us for rebates and administrative fee in connection with the utilization of product. These reserves are established in the same period that the related revenues are recognized, resulting in a reduction of revenues. Chargeback amounts are generally determined at the time of resale of products by the distributors.

Leases — In accordance with ASC 842 Leases, the Company determines whether an arrangement is a lease at inception. For leases where the Company is the lessee, right-of-use assets and operating lease liabilities are recognized based on the present value of remaining lease payments over the lease term. When the Company’s leases do not provide an implicit rate, the Company uses an estimated incremental borrowing rate based on the information available at lease commencement date in determining the present value of lease payments. Operating lease expense is recognized on a straight-line basis over the lease term. Variable lease costs such as common area costs and other operating costs are expensed as incurred. For all lease agreements, lease and non-lease components are combined. No right-of-use asset and related lease liability are recorded for leases with an initial term of 12 months or less.

Cash and cash equivalents—Cash and cash equivalents include short‑term securities, if any, with original maturities of less than ninety days. The Company maintains its cash and cash equivalents at insured financial institutions, the balances of which may, at times, exceed federally insured limits. Management believes that the risk of loss due to uninsured deposit is minimal.

Accounts receivable— Accounts receivables are primarily attributable to product sales to customers. The Company makes judgements as to its ability to collect outstanding receivables and provides an allowance for credit loss if and when collection becomes doubtful. Provisions are made based upon a specific review of all significant outstanding invoices and the quality and age of those invoices. As of December 31, 2023 and December 31, 2022, the Company recorded valuation allowances of $124,000 and $0, respectively. The Company believes the credit risks associated with its customers are not significant.

Factoring accounts receivable— Emmaus Medical, Inc., or Emmaus Medical, the Company’s indirect wholly owned subsidiary, entered into a purchase and sales agreement with Prestige Capital Finance, LLC or Prestige Capital, pursuant to which Emmaus Medical may offer and sell to Prestige Capital from time to time eligible accounts receivable in exchange for Prestige Capital’s down payment, or advance, to Emmaus Medical of 65% to 80% of the face amount of the accounts receivable, subject to a $7.5 million cap on advances at any time. The balance of the face amount of the accounts receivables will be reserved by Prestige Capital and paid to Emmaus Medical, less discount fees of Prestige Capital ranging from 2.25% to 7.25% of the face amount, as and when Prestige Capital collects the entire face amount of the accounts receivable. Emmaus Medical’s obligations to Prestige Capital under the purchase and sale agreement are secured by a security interest in the accounts receivable and all or substantially all other assets of Emmaus Medical. In connection with the purchase and sale agreement, Emmaus guarantees Emmaus Medical’s obligations under the purchase and sale agreement.

At December 31, 2023 and 2022, accounts receivable included approximately $1,514,000 and $730,000 of factored accounts receivable, respectively, and other current liabilities included approximately $24,000 and $55,000 of liabilities from factoring, respectively. For years ended December 31, 2023 and 2022, the Company incurred approximately $615,000 and $473,000, respectively, of factoring fees included in general and administrative expenses.

Inventories—Inventories consist of raw materials, finished goods and work-in-process and are valued on a first‑in, first‑out basis at the lesser of cost or net realizable value. Work‑in‑process inventories consist of L‑glutamine for the Company’s products that has not yet been packaged and labeled for sale. Substantially all raw materials purchase during the years ended December 31, 2023 and 2022 were supplied, directly or indirectly by one supplier. Inventories are presented net of reserves totaling $5.0 million as of December 31, 2023 and 2022.

Prepaid expenses and other current assets— Prepaid expenses and other current assets consist primarily of cost paid for future services or refunds from vendors which will occur within a year. Prepaid expenses include prepayment in insurance, subscription services, consulting and other services which are being amortized over the contract terms or recognized upon services are performed.

Property and equipment— Equipment, furniture and fixtures are recorded at historical cost and depreciated on a straight‑line basis over their estimated useful lives of five to seven years. Leasehold improvements are recorded at historical cost and amortized on a straight‑line basis over the shorter of their estimated useful lives or the lease terms. Maintenance and repairs are expensed as incurred, while major additions and improvements are capitalized. Gains and losses on disposition are included in other income (expenses), if any.

Impairment of long‑lived assets—The Company evaluates the carrying value of its long‑lived assets for impairment whenever events or changes in circumstances indicate that such carrying values may not be recoverable. The Management uses its best judgment based on the current facts and circumstances relating to the Company’s business when determining whether any significant impairment factors exist.

If the Company determines that the carrying values of long‑lived assets may not be recoverable based upon the existence of one or more indicators of impairment, the Company performs an undiscounted cash flow analysis to determine if impairment exists. If impairment exists, the Company measures the impairment based on the difference between the asset’s carrying amount and its fair value, and the impairment is reflected in the consolidated statement of operations in the period in which the long‑lived asset impairment is determined to have occurred. No impairment existed as of December 31, 2023 and 2022.

Research and development—Research and development consists of expenditures for the research and development of the Company’s products and product candidates, which primarily involve contract research, payroll‑related expenses and other related supplies. Research and development costs are expensed as incurred.

Share‑based compensation—The Company recognizes compensation cost for share‑based compensation awards over the service term of the recipients of the share‑based awards. The fair value of share‑based compensation is calculated using the Black‑Scholes‑Merton pricing model. The Black‑Scholes‑Merton model requires subjective assumptions regarding

future stock price volatility and expected time to exercise, which greatly affect the calculated values. The expected term of awards granted is calculated using the simplified method allowed under the Securities and Exchange Commission (“SEC”) Staff Accounting Bulletin Nos. 107 and 110. The risk‑free rate selected to value any grant is based on the U.S. Treasury rate on the grant date that corresponds to the expected term of the award.

Income taxes—The Company accounts for income taxes under the asset and liability method, wherein deferred tax assets and liabilities are recognized for the future tax consequences attributable to the differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period the enactment occurs. A valuation allowance is provided for certain deferred tax assets if it is more likely than not that the Company will not realize tax assets through the generation of future taxable income for the related jurisdictions.

When tax returns are filed, it is highly probable that some positions taken would be sustained upon examination by the taxing authorities, while others are subject to uncertainty about the merits of the position taken or the amount of the position that would be ultimately sustained. The benefit of a tax position is recognized in the financial statements in the period during which, based on all available evidence, management believes it is more likely than not that the position will be sustained upon examination, including the resolution of appeals or litigation processes, if any. Tax positions taken are not offset or aggregated with other positions. Tax positions that meet the more‑likely‑than‑not recognition threshold are recorded at the largest amount of tax benefit that is more than 50 percent likely of being realized upon examination by the applicable taxing authority. The portion of the benefits associated with tax positions taken that exceeds the amount measured as described above is reflected as a liability for unrecognized tax benefits along with any associated interest and penalties that would be payable to the taxing authorities upon examination.

As of December 31, 2023 and 2022, the Company had no unrecognized tax benefits and no positions which, in the opinion of management, would be reversed if challenged by a taxing authority. In the event the Company is assessed interest or penalties, such amounts will be classified as income tax expense in the financial statements.

Comprehensive loss—Comprehensive loss includes net loss and other comprehensive loss relating to foreign translation adjustments of the Company’s subsidiaries and the changes in fair value of investment in convertible bond classified as available for sale.

Equity method investment – Until December 2023, the Company owned 40% of the capital shares of EJ Holdings, Inc., or EJ Holdings, a variable interest entity (“VIE”). A VIE such as EJ Holdings is to be consolidated by its primary beneficiary if the beneficiary has both a) the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and b) the obligation to absorb losses of, or the right to receive benefits from, the VIE that could potentially be significant to the VIE. The Company determined that it does not meet the power criterion for consolidating EJ Holdings and, accordingly, accounted for its variable interest in EJ Holdings under the equity method. In December 2023, the Company sold and assigned its shares of EJ Holdings. Refer to Note 5 for further information.

Investment in convertible bond – The Company has measured its investment in convertible bond at fair value. The convertible bond is classified as available for sale and the changes in fair value are reported in other comprehensive loss for each reporting period.

Foreign currency translation—The Company’s reporting currency is the U.S. dollar. The functional currencies of its foreign subsidiaries are the primary currencies within the countries in which they operate. Assets and liabilities of their operations are translated into U.S. dollars at period‑end exchange rates, and revenues, if any, and expenses are translated into U.S. dollars at average exchange rates in effect during each reporting period. Adjustments resulting from the translation are reported in other comprehensive loss. Capital accounts are translated at historical foreign currency exchange rates.

Financial instruments—Financial instruments included in the financial statements are comprised of cash and cash equivalents, investment in convertible bond, accounts receivable, warrant derivative liabilities, accounts payable, certain accrued liabilities, convertible notes payable, notes payable, conversion feature liabilities and other contingent liabilities.

Fair value measurements—The Company defines fair value 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 in accordance with ASC 820. The Company measures fair value under a framework that provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in

active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described as follows:

Level 1: Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets.

Level 2: Inputs to the valuation methodology include:

Quoted prices for similar assets or liabilities in active markets;

Quoted prices for identical or similar assets or liabilities in inactive markets;

Inputs other than quoted prices that are observable for the asset or liability; and

Inputs that are derived principally from or corroborated by observable market data by correlation or other means.

If the asset or liability has a specified (contractual) term, the Level 2 inputs must be observable for substantially the full term of the asset or liability.

Level 3: Inputs to the valuation methodology are unobservable and significant to the fair value measurement.

The fair value measurement level of an asset or liability within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques used need to maximize the use of observable inputs and minimize the use of unobservable inputs. The carrying values of cash and cash equivalents, accounts receivables, other current assets, account payable and accrued expenses, and other current liabilities approximate fair value due to the short-term maturity of those instruments. The fair value of the Company's convertible debt instruments was determined based on Level 2 inputs. The carrying value of the debt was discounted based on allocating proceeds to other financial instruments within the arrangement as discussed in Note 7.

Certain outstanding warrants contain price adjustment provisions and, consequently, are accounted for as liabilities that are remeasured at fair value on a recurring basis using Level 3 inputs. The level 3 inputs in the valuation of the warrants include expected term and expected volatility as discussed in Note 8. There are no other assets or liabilities measured at fair value on a recurring basis.

Net loss per share—In accordance with ASC 260, “Earnings per Share,” the basic net loss per common share is computed by dividing net loss available to common stockholders by the weighted-average number of common shares outstanding. Dilutive net loss per share is computed in a similar manner, except that the denominator is increased to include the number of additional common shares that would have been outstanding if the potential common shares had been issued and if the additional common shares were dilutive. As of December 31, 2023 and 2022, there were 124,525,180 shares and 52,338,872 shares, respectively, of potentially dilutive securities outstanding. None of the potentially dilutive securities were included in the calculation of diluted loss per share since their effect would be anti‑dilutive for both periods presented.

Segment reporting—The Company operates in one reportable segment for primarily the marketing and sales of Endari®. In accordance with ASC 280, "Segment Reporting," the Company's Chief Operating Decision Maker ("CODM") is identified as Co-Presidents and Chief Financial Officer. Separate discrete financial information is available for evaluation by the CODM in making decisions regarding resource allocation and assessing performance. Based on the Company's organizational structure and CODM decision making process, all material operating units qualify for aggregation under the guidance.

Recent accounting pronouncements— Effective January 1, 2023, the Company adopted Accounting Standards Update 2016-13, Financial Instrument - Credit Losses (Topic 326), which introduces an approach based on expected losses to estimate credit losses on certain types of financial instruments. The new model, referred to as the current expected credit losses model, applies to financial assets subject to credit losses and measured at amortized costs, as well as certain off-balance sheet credit exposures. The adoption of this pronouncement did not have material impact on the Company's results of operations, financial condition or cash flow based on the current information.
