Unaudited Interim Financial Information

The accompanying interim condensed financial statements are unaudited and have been prepared on the same basis as the audited annual financial statements of the Company and, in the opinion of management, reflect all adjustments necessary for the fair presentation of the Company’s financial position as of March 31, 2026, and the results of its operations and its cash flows for the periods ended March 31, 2026 and 2025. The financial data and other information disclosed in these notes related to the three months ended March 31, 2026 and 2025 are also unaudited. The interim financial statements are condensed and generally do not repeat the disclosures in the annual financial statements. As such, the interim financial statements herein should be read in conjunction with the Company’s latest annual financial statements filed on Form 10-K on March 19, 2026. The results for the three months ended March 31, 2026, are not necessarily indicative of results to be expected for the year ending December 31, 2026, any other interim periods, or any future year or period.

Business Combination [Policy Text Block]

Acquisitions

The Company accounts for business acquisitions using the acquisition method of accounting. Under this method of accounting, assets acquired and liabilities assumed are recorded at their respective fair values at the date of the acquisition. When determining the fair values of assets acquired and liabilities assumed, management makes significant estimates and assumptions. The Company's estimates of fair value are based upon assumptions believed to be reasonable but that are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates. Any excess of the purchase price over the fair value of the net assets acquired is recognized as goodwill.

The Company accounts for acquisitions that do not meet the definition of a business as an asset acquisition. The determination of whether a transaction represents a business combination or an asset acquisition requires significant judgment, including an evaluation of whether the acquired set includes a substantive process and whether substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar assets. For transactions accounted for as asset acquisition, the Company allocates the purchase price, including transaction costs, to the individual assets acquired and liabilities assumed on a relative fair value basis. This allocation requires management to make significant estimates and assumptions, including the selection of valuation methodologies, discount rates, projected cash flows, and useful lives of acquired assets. Changes in these assumptions could result in materially different allocations of the purchase price, which may impact future amortization expense. In addition, because goodwill is not recognized in asset acquisitions, the assignment of value to identifiable intangible assets may be greater than in a business combination.

The Company amortizes finite-lived intangible assets over their estimated useful lives and evaluates indefinite-lived assets for impairment. The determination of useful lives and the timing of impairment assessments require significant judgment and may materially affect the Company’s results of operations. Critical estimates in valuing certain of the intangible assets acquired include:

●

future expected cash flows from customer contracts and license agreements;

●

historical and expected customer attrition rates and anticipated growth in revenues from acquired customers; and

●

discount rates.

Cash and Cash Equivalents, Policy [Policy Text Block]

Cash and Cash Equivalents

The Company considers all highly liquid investments with an original maturity of three months or less to be cash equivalents. All cash and cash equivalents are held in U.S. financial institutions or invested in short-term U.S. treasury bills or high-grade money market funds. From time to time, amounts deposited with its bank exceed federally insured limits. The Company believes the associated credit risk to be minimal.

Investment, Policy [Policy Text Block]

Inventories

The Company values its inventories at the lower of cost or net realizable value using the first-in, first-out method of valuation. The Company reviews its inventories for potential excess or obsolete issues on an ongoing basis and records a write-down if an impairment is identified. As of March 31, 2026 and December 31, 2025, inventories consisted of purchased finished goods, semi-finished goods and raw materials.

Goodwill and Intangible Assets, Intangible Assets, Policy [Policy Text Block]

Intangible Assets

The Company has historically capitalized payments it makes for licensed products when the payment is based on Food and Drug Administration (“FDA”) approval or near-term approval for the product and the cost is recoverable based on expected future cash flows from the product. In January 2026, the Company purchased the licensing rights to a product that has not received FDA approval and accordingly, is classified as In-Process Research and Development (“IPR&D”) within Intangible assets, net on the Company's Condensed Balance Sheets as of March 31, 2026. In February 2026, the Company entered into a licensing agreement to acquire the U.S. rights to HEMANGEOL® (propranolol) oral solution from Pierre Fabre Medicament Sas (“Pierre Fabre”), in which the Company paid Pierre Fabre $14,000 upfront. The Company accounted for this transaction as an asset acquisition, and after purchase accounting adjustments for inventory step-up costs of $1,131, and including acquisition related expenses of $100, the Company recorded $12,969 for the HEMANGEOL® intangible asset which is being amortized over its useful life of ten years.

Intangible assets are amortized on a straight-line basis over the estimated useful life of the product commencing on the approval date or the product acquisition date in accordance with ASC 350 — Intangibles - Goodwill and Other. The following table presents the Company's intangible assets as of March 31, 2026 and December 31, 2025:

Debt, Policy [Policy Text Block]

Deferred Financing Costs, Debt Discount and Detachable Debt-Related Warrants

Costs incurred to issue debt are deferred and recorded as a reduction to the debt balance in the accompanying Condensed Balance Sheets. The Company amortizes these costs over the expected term of the related debt under the effective interest method. Debt discounts related to the relative fair value of warrants issued in conjunction with debt are also recorded as a reduction to the debt balance and accreted over the expected term into interest expense using the effective interest method.

Patent Costs [Policy Text Block]

Patent Costs

All patent-related costs incurred in connection with filing and prosecuting patent applications are expensed as incurred due to the uncertainty about the successful award of a patent and the recovery of the expenditure. Amounts incurred are classified as general and administrative expenses.

Revenue [Policy Text Block]

Revenue Recognition for Contracts with Customers

The Company accounts for contracts with its customers in accordance with ASC 606 — Revenue from Contracts with Customers. ASC 606 applies to all contracts with customers, except for contracts that are within the scope of other standards. Under ASC 606, an entity recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that an entity determines are within the scope of ASC 606, the entity performs the following five 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 performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation.

At contract inception, once the contract is determined to be within the scope of ASC 606, the Company assesses the goods or services promised within each contract and determine those that are performance obligations and assesses whether each promised good or service is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied. Arrangements that include rights to additional goods or services that are exercisable at a customer’s discretion are generally considered options. The Company assesses whether these options provide a material right to the customer and, if so, they are considered performance obligations. The exercise of a material right is accounted for as a contract modification for accounting purposes.

The Company recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) each performance obligation is satisfied at a point in time. For the three months ended March 31, 2026 and 2025, all revenues recognized in the Condensed Statements of Operations were point in time sales to the Company's customers.

Milestone Payments – If a commercial contract arrangement includes development and regulatory milestone payments, the Company will evaluate whether the milestone conditions have been achieved and if it is probable that a significant revenue reversal would not occur before recognizing the associated revenue. Milestone payments that are not within the Company’s control or the licensee’s control, such as regulatory approvals, are generally not considered probable of being achieved until those approvals are received.

Royalties – For arrangements that include sales-based royalties, including milestone payments based on a level of sales, which are the result of a customer-vendor relationship and for which the license is deemed to be the predominant item to which the royalties relate, the Company will recognize revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied or partially satisfied.

The Company sells its INCRELEX®, HEMANGEOL®, ALKINDI SPRINKLE®, KHINDIVI™, DESMODA™, GALZIN®, PKU GOLIKE®, Carglumic Acid, Betaine Anhydrous, and Nitisinone products to pharmacy distributor customers which provide order fulfilment and inventory storage/distribution services. The Company uses a third-party logistics (“3PL”) vendor to process and fulfill orders and has concluded it is the principal in the sales to wholesalers because it controls access to the 3PL vendor services rendered and directs the 3PL vendor activities.

For the Company's INCRELEX®, HEMANGEOL®, ALKINDI SPRINKLE®, KHINDIVI™, DESMODA™, GALZIN®, PKU GOLIKE®, Carglumic Acid, Betaine Anhydrous, and Nitisinone products, the Company bills at the initial product list price which are subject to offsets for patient co-pay assistance and potential state Medicaid reimbursements which are recorded as a reduction of net revenues at the date of sale/shipment. INCRELEX®, HEMANGEOL®, ALKINDI SPRINKLE®, KHINDIVI™, DESMODA™, GALZIN®, PKU GOLIKE®, Carglumic Acid, Betaine Anhydrous, and Nitisinone product sales are not subject to returns. Upon recognition of revenue from product sales, the estimated amounts of chargebacks, prompt pay discounts and state Medicaid are in sales reserves, accrued liabilities and net accounts receivable.

The Company estimates the transaction price when it receives each purchase order taking into account the expected reductions of the selling price initially billed to the wholesaler/distributor arising from all of the above factors. The Company has developed estimates for future returns and chargebacks and the impact of other discounts and fees it pays, although INCRELEX®, HEMANGEOL®, ALKINDI SPRINKLE®, KHINDIVI™, DESMODA™, GALZIN®, PKU GOLIKE®, Carglumic Acid, Betaine Anhydrous, and Nitisinone sales are not subject to returns.

The Company stores its INCRELEX®, HEMANGEOL®, ALKINDI SPRINKLE®, KHINDIVI™, DESMODA™, GALZIN®, PKU GOLIKE®, Carglumic Acid, Betaine Anhydrous and Nitisinoneproducts inventory at its pharmacy distributor customer locations, and sales are recorded when stock is pulled and shipped to fulfill specific patient orders.

The state Medicaid rebate and related liability are estimated based on monthly sales, historical experience of claims submitted by the various states and jurisdictions, historical rebate rates and estimated lag time of the rebate invoices.

Research and Development Expense, Policy [Policy Text Block]

Research and Development Expenses

Research and development (“R&D”) expenses include both internal R&D activities and external contracted services. Internal R&D activity expenses include salaries, benefits and stock-based compensation and other costs to support the Company’s R&D operations. External contracted services include product development efforts such as certain product licensor milestone payments, clinical trial activities, manufacturing and control-related activities and regulatory costs. R&D expenses are charged to operations as incurred. The Company reviews and accrues R&D expenses based on services performed and may, from time to time, make estimates of those costs applicable as to the stage of completion of each project. Actual results could differ from the Company’s estimates. Nonrefundable advance payments for goods or services to be received in the future for use in R&D activities are recorded as prepaid expenses and are expensed as the related goods are delivered or the services are performed.

Income Tax, Policy [Policy Text Block]

Income Taxes

The Company accounts for income taxes under the provisions of ASC 740 - Income Taxes. As part of the process of preparing the Company’s financial statements, the Company must estimate the actual current tax liabilities and assess temporary differences resulting from differing treatment of items for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included within the Condensed Balance Sheets. The Company must assess the likelihood that the deferred tax assets will be recovered from future taxable income and, to the extent the Company believes that recovery is not likely, a valuation allowance must be established. To the extent the Company establishes a valuation allowance or increase or decrease to this allowance in a period, the impact will be included in income tax expense in the Condensed Statements of Operations. As of March 31, 2026 and December 31, 2025, the Company has established a 100% valuation reserve against its deferred tax assets. See Note 10 for further information.

Fair Value Measurement, Policy [Policy Text Block]

Fair Value Measurements

We measure certain of our assets and liabilities at fair value. Fair value represents 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. Fair value accounting requires characterization of the inputs used to measure fair value into a three-level fair value hierarchy as follows:

Level 1 — Inputs based on quoted prices in active markets for identical assets or liabilities. An active market is a market in which transactions occur with sufficient frequency and volume to provide pricing information on an ongoing basis.

Level 2 — Observable inputs that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from sources independent from the entity.

Level 3 — Unobservable inputs that reflect the entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available.

Fair value measurements are classified based on the lowest level of input that is significant to the measurement. The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment, which may affect the valuation of the assets and liabilities and their placement within the fair value hierarchy levels. The determination of the fair values stated below take into account the market for the Company’s financials, assets and liabilities, the associated credit risk and other factors as required. The Company considers active markets as those in which transactions for the assets or liabilities occur in sufficient frequency and volume to provide pricing information on an ongoing basis.

The Company’s financial instruments include cash and cash equivalents, accounts receivable, accounts payable, accrued liabilities, and debt obligation. The carrying amounts of these financial instruments approximate their fair values due to the short-term maturities of these instruments. Based on borrowing rates currently available to the Company, the carrying value of the debt obligation approximates its fair value.
