Mar. 31, 2026
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) for interim financial information and the rules and regulations of the Securities and Exchange Commission (“SEC”). In the opinion of the Company’s management, the accompanying unaudited condensed consolidated financial statements reflect all adjustments, consisting of normal, recurring adjustments, considered necessary for a fair presentation of the results for the interim periods ended March 31, 2026 and 2025. Although management believes that the disclosures in these unaudited condensed consolidated financial statements are adequate to make the information presented not misleading, certain information and footnote disclosures normally included in consolidated financial statements that have been prepared in accordance with U.S. GAAP have been omitted pursuant to the rules and regulations of the SEC. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the Company’s financial statements and notes related thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025, filed with the SEC on March 19, 2026. The interim results for the three months ended March 31, 2026 are not necessarily indicative of the results to be expected for the year ending December 31, 2026 or for any future interim periods. As described in “Note 2—Restatement of Previously Issued Financial Statements”, the Company’s condensed consolidated financial statements as of and for the three months ended March 31, 2026 are restated in this Quarterly Report on Form 10-Q/A (Amendment No. 1) (this “Amendment”) to correct a misapplication of ASC 820, Fair Value Measurements, related to the certain Level 3 fair value measurements of the Company’s convertible debt, including valuation methodologies, specific significant valuation assumptions, and inputs, in the Company’s previously issued condensed consolidated financial statements for such periods. The restated condensed consolidated financial statements are indicated as “As Restated” in the condensed consolidated financial statements and accompanying notes, as applicable.
Principles of Consolidation	Principles of Consolidation The condensed consolidated financial statements include the accounts of Pelthos Therapeutics Inc. and its wholly owned subsidiaries, LNHC, Chromocell Therapeutics Australia Pty. Ltd, and Channel Pharmaceutical Corporation (“CPC”). All significant intercompany balances and transactions have been eliminated.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make 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 the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates made by management include provisions for distribution service fees, co-payment assistance, government and payor rebates and fees, inventory net realizable value, useful lives of amortizable intangible assets, valuation of assets and liabilities in business combinations, valuation of convertible debt, developmental timelines related to licensed products, valuation of future obligations related to licensees and contractual payments, deferred income taxes and contingencies. Actual results may differ materially and adversely from these estimates. To the extent there are material differences between the estimates and actual results, the Company’s future results of operations will be affected.
Business Acquisitions	Business Acquisitions The Company accounts for business acquisitions using the acquisition method of accounting in accordance with ASC 805. ASC 805 requires, among other things, that assets acquired and liabilities assumed be recognized at their fair values, as determined in accordance with ASC 820, Fair Value Measurements (“ASC 820”), as of the acquisition date. For certain assets and liabilities, book value approximates fair value. In addition, ASC 805 establishes that consideration transferred be measured at the closing date of the acquisition at the then-current market price. Under ASC 805, acquisition-related costs (i.e., advisory, legal, valuation and other professional fees) are expensed in the period in which the costs are incurred. The application of the acquisition method of accounting requires the Company to make estimates and assumptions related to the estimated fair values of net assets acquired, which require significant management judgment.
Reclassifications	Reclassifications Certain amounts in the Company’s condensed consolidated statements of operations for the three months ended March 31, 2025 have been reclassified to conform to the current presentation, in addition to certain line items within the historical condensed consolidated statements of cash flows.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents.
Restricted Cash	Restricted Cash Restricted cash as of March 31, 2026 relates to a deposit account securing the Company’s corporate credit card program and a deposit account set up for the benefit of Nomis RoyaltyVest LLC associated with the ZELSUVMI Royalty Agreement, as described in Note 10 — “License and Other Agreements”.
Accounts Receivable, Net	Accounts Receivable, Net Accounts receivables are stated as amounts due, net of estimates for discounts offered in customer contracts and any expected credit losses. The Company estimates expected credit losses using the “expected loss” model, which is based on an assessment of the collectability of customer accounts, including collection history, credit quality, the age of past-due balances, current conditions, and reasonable and supportable future conditions that might impact a customer’s ability to pay. The allowance for credit losses is periodically analyzed and adjusted as needed through a charge to selling, general and administrative expense. Amounts deemed to be uncollectible are charged against the allowance for credit losses. The Company does not assess whether a contract has a significant financing component if the expectation at contract inception is such that the period between the transfer of the promised good to the customer and receipt of payment will be one year or less. As of March 31, 2026, the Company did not record an allowance for credit losses, based on its history of collections from its customers.
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments that potentially subject the Company to a concentration of credit risk consist principally of cash, cash equivalents and accounts receivable. The Company places its cash and cash equivalents with financial institutions, and these deposits may at times be in excess of federally insured limits. In addition, the Company assesses the creditworthiness of its customers on an on-going basis. As of March 31, 2026, three of the Company’s wholesaler customers accounted for 92% of its total gross accounts receivable balance at 39%, 28% and 25%, respectively. In addition, for the three months ended March 31, 2026, these three wholesalers accounted for 92% of gross revenue at 36%, 28% and 28%, respectively.
Inventory	Inventory The Company measures inventory using the first-in, first-out method and values inventory at the lower of cost or net realizable value. Inventory value includes costs related to materials, manufacturing, labor, conversion and overhead expenses. The Company adjusts its inventory for potentially obsolete inventory. The adjustment for obsolescence is generally an estimate of the value of inventory that is expected to expire in the future based on projected sales volume and product expiration or expected sell-by dates. These assumptions require the Company to analyze the aging of and forecasted demand for its inventory and make estimates regarding future product sales. Prior to obtaining initial regulatory approval for ZELSUVMI in January 2024, inventory costs related to the production of pre-launch inventory were expensed as research and development costs. Subsequent to January 5, 2024, the date of the FDA’s approval of ZELSUVMI, inventory costs were capitalized by LNHC. As part of the Merger, certain inventoried items were revalued subject to ASC 805.
Property and Equipment, Net	Leasehold improvements are amortized over the shorter of the life of the lease or the useful life of the improvements. Expenditures for maintenance and repairs are expensed as incurred. Improvements and betterments that add new functionality or extend the useful life of an asset are capitalized. Leases for real estate often include tenant improvement allowances, which the Company assesses according to applicable accounting guidance to determine the appropriate owner, and capitalizes such tenant improvement assets accordingly.
Intangible Assets, Net and Goodwill	Intangible Assets, Net and Goodwill Intangible assets represent certain identifiable intangible assets, including product rights consisting of pharmaceutical product licenses and patents. Amortization for pharmaceutical products licenses is computed using the straight-line method based on the lesser of the term of the agreement and the useful life of the license. Amortization for pharmaceutical patents is computed using the straight-line method based on the useful life of the patent. Definite-lived intangible assets are reviewed for impairment whenever events or circumstances indicate that carrying amounts may not be recoverable. In the event impairment indicators are present or if other circumstances indicate that an impairment might exist, then management compares the future undiscounted cash flows directly associated with the asset or asset group to the carrying amount of the asset group being determined for impairment. If those estimated cash flows are less than the carrying amount of the asset group, an impairment loss is recognized. An impairment loss is recognized to the extent that the carrying amount exceeds the asset’s fair value. Considerable judgment is necessary to estimate the fair value of these assets, accordingly, actual results may vary significantly from such estimates. Indefinite-lived intangible assets, including goodwill, are not amortized. The Company tests the carrying amounts of goodwill for recoverability on an annual basis on July 1 or when events or changes in circumstances indicate evidence that a potential impairment exists, using a fair value based test. Goodwill, which has an indefinite useful life, represents the excess of cost over fair value of net assets acquired. Goodwill is reviewed for impairment at the reporting unit level at least annually, or more frequently if an event occurs indicating the potential for impairment. During a goodwill impairment review, management performs an assessment of qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than the carrying amount, including goodwill. The qualitative factors include, but are not limited to, macroeconomic conditions, industry and market considerations, and the overall financial performance. If, after assessing the totality of these qualitative factors, management determines that it is not more likely than not that the fair value of reporting unit is less than the carrying amount, then no additional assessment is deemed necessary.
Leases	Leases The Company leases office space under non-cancelable lease agreements. The Company applies the accounting guidance in ASC 842, Leases (“ASC 842”). As such, the Company assesses all arrangements, that convey the right to control the use of property, plant and equipment, at inception, to determine if it is, or contains, a lease based on the unique facts and circumstances present in that arrangement. For those leases identified, the Company determines the lease classification, recognition, and measurement at the lease commencement date. For arrangements that contain a lease, the Company: (i) identifies lease and non-lease components; (ii) determines the consideration in the contract; (iii) determines whether the lease is an operating or financing lease; and (iv) recognizes lease Right of Use (“ROU”) assets and corresponding lease liabilities. Lease liabilities are recorded based on the present value of lease payments over the expected lease term. The corresponding ROU asset is measured from the initial lease liability, adjusted by (i) accrued or prepaid rents; (ii) remaining unamortized initial direct costs and lease incentives; and (iii) any impairments of the ROU asset. The Company elected the practical expedient to not separate non-lease components from the lease components. Fixed lease payments on operating leases are recognized over the expected term of the lease on a straight-line basis. Variable lease expenses that are not considered fixed are expensed as incurred. Fixed and variable lease expense on operating leases is recognized within operating expenses within the condensed consolidated statements of operations. The Company has elected the short-term lease exemption and, therefore, does not recognize an ROU asset or corresponding liability for lease arrangements with an original term of 12 months or less. The interest rate implicit in the Company’s lease contracts is typically not readily determinable and as such, the Company uses its incremental borrowing rate based on the information available at the lease commencement date, which represents an internally developed rate that would be incurred to borrow, on a collateralized basis, over a similar term, an amount equal to the lease payments in a similar economic environment.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized for an amount by which the carrying amount of the asset exceeds the fair value of the asset. The Company did not identify indicators of impairment for the long-lived assets during the three months ended March 31, 2026.
Fair Value Measurements and Fair Value of Financial Instruments	Fair Value Measurements and Fair Value of Financial Instruments The Company determines fair value, per ASC 820, based on assumptions that market participants would use in pricing an asset or liability in the principal or most advantageous market. When considering market participant assumptions in fair value measurements, the following fair value hierarchy distinguishes between observable and unobservable inputs, which are categorized in one of the following levels: •Level 1 Inputs are unadjusted quoted prices in active markets for identical assets or liabilities available at the measurement date. •Level 2 Inputs are unadjusted quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, inputs other than quoted prices that are observable, and inputs derived from or corroborated by observable market data. •Level 3 Inputs are unobservable inputs which reflect the reporting entity’s own assumptions on what assumptions the market participants would use in pricing the asset or liability based on the best available information.
Revenue Recognition	Revenue Recognition Pursuant to ASC 606, Revenue from Contracts with Customers (“ASC 606”), the Company recognizes revenue when a customer obtains control of promised goods or services. Revenue is recognized in an amount that reflects the consideration that the Company expects to receive in exchange for those goods or services. 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 performance obligations in the contract; and (v) recognize revenue when (or as) a performance obligation is satisfied. Net Product Revenues The Company sells ZELSUVMI to national and regional wholesalers in the United States. The wholesalers are considered the Company’s customers for accounting purposes. Revenue from product sales is recognized when the customer obtains control of the Company’s product, which typically occurs on delivery. Revenue from product sales is recorded at the transaction price, net of estimates for variable consideration consisting of prompt-pay discounts, distribution service fees, government rebates, co-payment assistance and payor rebates and administration fees for which reserves are established. These reserves are based on estimates of the amounts earned or to be claimed on the related sales and are classified as reductions of accounts receivable (if the amount is payable to the customer) or a liability (if the amount is payable to a party other than the customer). Variable consideration is estimated using the expected-value amount method, which is the sum of probability-weighted amounts in a range of possible consideration amounts. In making these estimates, the Company considers historical data, including patient mix and inventory sold to customers that has not yet been dispensed. Actual amounts of consideration ultimately received may differ from the Company’s estimates. If actual results vary materially from the Company’s estimates, the Company will adjust these estimates, which will affect net product sales and earnings in the period such estimates are adjusted. These items, as applicable based on current contractual agreements and obligations on behalf of the Company, include: •Prompt-Pay Discounts — The Company generally provides discounts on product sales to its customers for prompt payment. The Company estimates that its customers will earn these discounts. These discounts are recorded as a reduction of gross revenue and accounts receivable at the time such revenue is recognized. •Distribution Service Fees — The Company pays certain distribution service fees, such as fees for certain data that customers provide to the Company or for distribution services provided to the Company. Fees paid to its customers are recorded as a reduction of gross revenue and accounts receivable, unless the payment is: (i) for a distinct good or service from the customer; and (ii) the Company can reasonably estimate the fair value of the goods or services received. If both conditions are met, the Company records the consideration paid to the customer as selling, general and administrative expense. •Co-payment Assistance — Co-payment assistance represents financial assistance to qualified patients, assisting them with prescription drug co-payments required by insurance. The program is administered by a third-party on the Company's behalf. Co-payment assistance is recorded as a reduction of revenue and a current liability is established and included in accrued expenses at the time such revenue is recognized. •Government Rebates — The Company estimates government rebates, primarily Medicaid, based upon a range of possible outcomes for the estimated patient mix. Medicaid rebates relate to the Company's estimated obligations to states under reimbursement arrangements. Rebates are recorded as a reduction of gross revenue and a current liability is established and included in accrued expenses at the time such gross revenue is recognized. The amount of the rebate for each unit of product reimbursed by the state Medicaid program is established by law and is adjusted upward if the wholesale acquisition cost increases more than inflation (measured by the Consumer Price Index). The liability for Medicaid rebates consists of: (i) estimated current quarter claims; (ii) estimated prior quarter claims for which an invoice has not been received; (iii) prior quarter claims based on unpaid invoices received; and (iv) estimated claims for inventory in the distribution channel at period end. •Payor Rebates and Administration Fees — Payor rebates and administration fees represent the estimated obligations to third parties, primarily benefit managers. The payor rebates and administration fees result from formulary position, price increase limit allowances (price protection) and administration fees. The liability payor rebates and administration fees are based on the estimated payors buying patterns and the resulting applicable contractual rebate rate(s) to be earned over a contractual period. Payor rebates and administration fees are recorded as a reduction of revenue and a liability is established and included in accrued expenses at the time such revenue is recognized. License and Collaboration Revenues The Company has one agreement related to an out-license of intellectual property to a third party. Per ASC 606, the Company determines if there are distinct performance obligations identified in the arrangement. The Company recognizes revenues from non-refundable, upfront fees allocated to the license when the license is transferred to the customer and the customer is able to use and benefit from the license. For licenses that are bundled with other promises, the Company’s management utilizes judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the estimated performance period and the appropriate method of measuring progress during the performance period for purposes of recognizing revenue. The Company re-evaluates the estimated performance period and measure of progress each reporting period and, if necessary, adjusts related revenue recognition accordingly. These arrangements often include milestone as well as royalty or profit-share payments, contingent upon the occurrence of certain future events linked to the success of the asset in development, as well as expense reimbursements from or payments to the collaboration partner. Because of the risk that products in development will not receive regulatory approval, the Company does not recognize any contingent payments until regulatory approval becomes probable. Future sales-based royalties are not recorded until the subsequent sale occurs.
Cost of Goods Sold	Cost of Goods Sold Cost of goods sold includes direct and indirect costs related to the manufacture, production, packaging, and distribution of the Company’s commercial products. These costs primarily consist of manufacturing costs, including allocated overhead, supply costs, third-party logistics and distribution expenses, quality control and assurance costs, and freight and shipping charges incurred in fulfilling customer orders. Additionally, the Company’s product is subject to strict quality control and monitoring that is performed throughout the manufacturing process, including release of work-in-process to finished goods. In the event that certain batches or units of product do not meet quality specifications, the Company records a write-down of any potential unmarketable inventory to its estimated net realizable value. As part of the Merger, certain inventoried items were revalued subject to ASC 805. See Note 4 — “Acquisition of LNHC, Inc.” for additional detail. The amount of expense related to inventory write down as a result of excess, obsolescence, scrap, or other reasons is recorded as cost of goods sold in the condensed consolidated statements of operations.
Selling, General and Administrative Expense	Selling, General and Administrative Expense Selling, general and administrative (“SG&A”) expense consists of personnel and non-personnel expenses to support growing sales of ZELSUVMI. Personnel-related expenses include salaries, incentive pay, benefits and share-based compensation for personnel engaged in sales, marketing, regulatory, quality, medical, non-capitalizable manufacturing, finance, information technology and administrative functions. As the majority of the Company’s contracts are short-term in nature, sales commissions are generally recorded as selling, general and administrative expense when incurred as the amortization period would have been less than one year. Non-personnel-related expense includes: (i) selling, patient services, pharmacovigilance, marketing, advertising, travel, sponsorships and trade shows; and (ii) other general and administrative costs, including consulting, legal, patent, insurance, accounting, information technology and facilities. The Company uses a third-party logistics provider (“3PL”) to perform a full order-to-cash service, which includes warehousing and shipping directly to its customers on its behalf. Activities performed by the 3PL are recorded in SG&A. SG&A expenses are recognized as they are incurred. Royalty and/or milestone payments due to third parties under license arrangements for commercial products are expensed within SG&A and recorded as a current liability in the periods in which the obligation is incurred.
Research and Development Expense	Research and Development Expense Research and development (“R&D”) expense consists of personnel and non-personnel expenses. Personnel-related expense includes salaries, bonus, benefits and share-based compensation for personnel engaged in research and development functions. Non-personnel-related expense includes subcontractors and materials used for R&D activities, development, clinical trials, clinical supply and distribution, and other professional services. R&D expenses are recognized as they are incurred based on actual work completed through monitoring invoices received and discussions with internal personnel and external service providers as to the progress or stage of completion of preclinical activities, clinical studies and related supporting services for non-commercial assets. Contingent milestone payments due to third parties under R&D arrangements or license agreements, are expensed within R&D and recorded as a current liability in the periods in which the obligation is incurred.
Stock-Based Compensation	Stock-Based Compensation The Company accounts for stock-based compensation costs under the provisions of ASC 718, Compensation—Stock Compensation (“ASC 718”), which requires the measurement and recognition of compensation expense related to the fair value of stock-based compensation awards that are ultimately expected to vest. Stock-based compensation expense recognized includes the compensation cost for all stock-based payments granted to employees, officers, and directors based on the grant date fair value estimated in accordance with the provisions of ASC 718. ASC 718 is also applied to awards modified, repurchased, or cancelled during the periods reported. Stock-based compensation is recognized as expense over the employee’s requisite vesting period and over the non-employee’s period of providing goods or services.
Basic and Diluted Net Loss per Common Share	Basic and Diluted Net Loss per Common Share Basic loss per common share is computed by dividing the net loss by the weighted average number of shares of Common Stock outstanding for each year. Diluted loss per share is computed by dividing the net loss by the weighted average number of shares of Common Stock outstanding plus the dilutive effect of shares issuable through the common stock equivalents. The weighted-average number of common shares outstanding excludes common stock equivalents because their inclusion would be anti-dilutive.
Income Taxes	Income Taxes The Company accounts for income taxes pursuant to the provision of ASC 740 “Accounting for Income Taxes,” (“ASC 740”) which requires, among other things, an asset and liability approach to calculating deferred income taxes. The asset and liability approach requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities. A valuation allowance is provided to offset any net deferred tax assets for which management believes it is more likely than not that the net deferred asset will not be realized. The Company follows the provision of the ASC 740 related to Accounting for Uncertain Income Tax Positions. When tax returns are filed, it is more likely than not 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. In accordance with the guidance of ASC 740, the benefit of a tax position is recognized in the condensed consolidated 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 measured as the largest amount of tax benefit that is more than 50% likely of being realized upon settlement with the applicable taxing authority. The portion of the benefits associated with tax positions taken that exceeds the amount measured as described above should be reflected as a liability for uncertain tax benefits in the accompanying condensed consolidated balance sheet along with any associated interest and penalties that would be payable to the taxing authorities upon examination. The Company believes its tax positions will more likely than not be upheld upon examination. As such, the Company has not recorded a liability for uncertain tax benefits. The federal and state income tax returns of the Company are subject to examination by the Internal Revenue Service and state taxing authorities, generally for three years after they were filed.
Segment Information	Segment Information Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the Company’s Chief Executive Officer, the chief operating decision-maker (“CODM”). For accounting purposes, the CODM is making decisions regarding resource allocation and assessing performance based on consolidated net loss as if presented in the Company’s condensed consolidated financial statements. The Company views its operations and manages its business in two operating segments, the Commercial Operations segment, and the Research and Development Operations segment.
Related Party Transactions	Related Party Transactions The Company has historically separately presented certain related party transactions and balances in its condensed consolidated financial statements.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires disaggregated information about a reporting entity’s effective tax rate reconciliation, as well as information related to income taxes paid to enhance the transparency and decision usefulness of income tax disclosures. This ASU will be effective for the annual periods beginning after December 15, 2024. The Company has adopted ASU 2023-09 for the year-ended December 31, 2025. In November 2024, the FASB issued ASU No. 2024-03, “Disaggregation of Income Statement Expenses,” which requires disclosures of certain disaggregated income statement expense captions into specified categories within the footnotes to the financial statements. The requirements of the ASU are effective for annual periods beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027, with early adoption permitted. The requirements will be applied prospectively with the option for retrospective application. The Company is currently evaluating the impact ASU No. 2024-03 will have on its condensed consolidated financial statements. Other new accounting pronouncements issued, but not effective until after March 31, 2026, did not and are not expected to have a material impact on the Company’s financial position, results of operations or liquidity.

BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)

3 Months Ended

Mar. 31, 2026

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) for interim financial information and the rules and regulations of the Securities and Exchange Commission (“SEC”). In the opinion of the Company’s management, the accompanying unaudited condensed consolidated financial statements reflect all adjustments, consisting of normal, recurring adjustments, considered necessary for a fair presentation of the results for the interim periods ended March 31, 2026 and 2025. Although management believes that the disclosures in these unaudited condensed consolidated financial statements are adequate to make the information presented not misleading, certain information and footnote disclosures normally included in consolidated financial statements that have been prepared in accordance with U.S. GAAP have been omitted pursuant to the rules and regulations of the SEC.

The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the Company’s financial statements and notes related thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025, filed with the SEC on March 19, 2026. The interim results for the three months ended March 31, 2026 are not necessarily indicative of the results to be expected for the year ending December 31, 2026 or for any future interim periods.

As described in “Note 2—Restatement of Previously Issued Financial Statements”, the Company’s condensed consolidated financial statements as of and for the three months ended March 31, 2026 are restated in this Quarterly Report on Form 10-Q/A (Amendment No. 1) (this “Amendment”) to correct a misapplication of ASC 820, Fair Value Measurements, related to the certain Level 3 fair value measurements of the Company’s convertible debt, including valuation methodologies, specific significant valuation assumptions, and inputs, in the Company’s previously issued condensed consolidated financial statements for such periods. The restated condensed consolidated financial statements are indicated as “As Restated” in the condensed consolidated financial statements and accompanying notes, as applicable.

Principles of Consolidation

The condensed consolidated financial statements include the accounts of Pelthos Therapeutics Inc. and its wholly owned subsidiaries, LNHC, Chromocell Therapeutics Australia Pty. Ltd, and Channel Pharmaceutical Corporation (“CPC”). All significant intercompany balances and transactions have been eliminated.

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make 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 the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Significant estimates made by management include provisions for distribution service fees, co-payment assistance, government and payor rebates and fees, inventory net realizable value, useful lives of amortizable intangible assets, valuation of assets and liabilities in business combinations, valuation of convertible debt, developmental timelines related to licensed products, valuation of future obligations related to licensees and contractual payments, deferred income taxes and contingencies. Actual results may differ materially and adversely from these estimates. To the extent there are material differences between the estimates and actual results, the Company’s future results of operations will be affected.

Business Acquisitions

The Company accounts for business acquisitions using the acquisition method of accounting in accordance with ASC 805. ASC 805 requires, among other things, that assets acquired and liabilities assumed be recognized at their fair values, as determined in accordance with ASC 820, Fair Value Measurements (“ASC 820”), as of the acquisition date. For certain assets and liabilities, book value approximates fair value. In addition, ASC 805 establishes that consideration transferred be measured at the closing date of the acquisition at the then-current market price. Under ASC 805, acquisition-related costs (i.e., advisory, legal, valuation and other professional fees) are expensed in the period in which the costs are incurred. The application of the acquisition method of accounting requires the Company to make estimates and assumptions related to the estimated fair values of net assets acquired, which require significant management judgment.

Reclassifications

Certain amounts in the Company’s condensed consolidated statements of operations for the three months ended March 31, 2025 have been reclassified to conform to the current presentation, in addition to certain line items within the historical condensed consolidated statements of cash flows.

Cash and Cash Equivalents

The Company considers all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents.

Restricted Cash

Restricted cash as of March 31, 2026 relates to a deposit account securing the Company’s corporate credit card program and a deposit account set up for the benefit of Nomis RoyaltyVest LLC associated with the ZELSUVMI Royalty Agreement, as described in Note 10 — “License and Other Agreements”.

Accounts Receivable, Net

Accounts receivables are stated as amounts due, net of estimates for discounts offered in customer contracts and any expected credit losses. The Company estimates expected credit losses using the “expected loss” model, which is based on an assessment of the collectability of customer accounts, including collection history, credit quality, the age of past-due balances, current conditions, and reasonable and supportable future conditions that might impact a customer’s ability to pay. The allowance for credit losses is periodically analyzed and adjusted as needed through a charge to selling, general and administrative expense. Amounts deemed to be uncollectible are charged against the allowance for credit losses. The Company does not assess whether a contract has a significant financing component if the expectation at contract inception is such that the period between the transfer of the promised good to the customer and receipt of payment will be one year or less. As of March 31, 2026, the Company did not record an allowance for credit losses, based on its history of collections from its customers.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to a concentration of credit risk consist principally of cash, cash equivalents and accounts receivable. The Company places its cash and cash equivalents with financial institutions, and these deposits may at times be in excess of federally insured limits. In addition, the Company assesses the creditworthiness of its customers on an on-going basis. As of March 31, 2026, three of the Company’s wholesaler customers accounted for 92% of its total gross accounts receivable balance at 39%, 28% and 25%, respectively. In addition, for the three months ended March 31, 2026, these three wholesalers accounted for 92% of gross revenue at 36%, 28% and 28%, respectively.

Inventory

The Company measures inventory using the first-in, first-out method and values inventory at the lower of cost or net realizable value. Inventory value includes costs related to materials, manufacturing, labor, conversion and overhead expenses. The Company adjusts its inventory for potentially obsolete inventory. The adjustment for obsolescence is generally an estimate of the value of inventory that is expected to expire in the future based on projected sales volume and product expiration or expected sell-by dates. These assumptions require the Company to analyze the aging of and forecasted demand for its inventory and make estimates regarding future product sales.

Prior to obtaining initial regulatory approval for ZELSUVMI in January 2024, inventory costs related to the production of pre-launch inventory were expensed as research and development costs. Subsequent to January 5, 2024, the date of the FDA’s approval of ZELSUVMI, inventory costs were capitalized by LNHC. As part of the Merger, certain inventoried items were revalued subject to ASC 805.

Property and Equipment, Net

Leasehold improvements are amortized over the shorter of the life of the lease or the useful life of the improvements. Expenditures for maintenance and repairs are expensed as incurred. Improvements and betterments that add new functionality or extend the useful life of an asset are capitalized. Leases for real estate often include tenant improvement allowances, which the Company assesses according to applicable accounting guidance to determine the appropriate owner, and capitalizes such tenant improvement assets accordingly.

Intangible Assets, Net and Goodwill

Intangible assets represent certain identifiable intangible assets, including product rights consisting of pharmaceutical product licenses and patents. Amortization for pharmaceutical products licenses is computed using the straight-line method based on the lesser of the term of the agreement and the useful life of the license. Amortization for pharmaceutical patents is computed using the straight-line method based on the useful life of the patent.

Definite-lived intangible assets are reviewed for impairment whenever events or circumstances indicate that carrying amounts may not be recoverable. In the event impairment indicators are present or if other circumstances indicate that an impairment might exist, then management compares the future undiscounted cash flows directly associated with the asset or asset group to the carrying amount of the asset group being determined for impairment. If those estimated cash flows are less than the carrying amount of the asset group, an impairment loss is recognized. An impairment loss is recognized to the extent that the carrying amount exceeds the asset’s fair value. Considerable judgment is necessary to estimate the fair value of these assets, accordingly, actual results may vary significantly from such estimates.

Indefinite-lived intangible assets, including goodwill, are not amortized. The Company tests the carrying amounts of goodwill for recoverability on an annual basis on July 1 or when events or changes in circumstances indicate evidence that a potential impairment exists, using a fair value based test.

Goodwill, which has an indefinite useful life, represents the excess of cost over fair value of net assets acquired. Goodwill is reviewed for impairment at the reporting unit level at least annually, or more frequently if an event occurs indicating the potential for impairment. During a goodwill impairment review, management performs an assessment of qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than the carrying amount, including goodwill. The qualitative factors include, but are not limited to, macroeconomic conditions, industry and market considerations, and the overall financial performance. If, after assessing the totality of these qualitative factors, management determines that it is not more likely than not that the fair value of reporting unit is less than the carrying amount, then no additional assessment is deemed necessary.

Leases

The Company leases office space under non-cancelable lease agreements. The Company applies the accounting guidance in ASC 842, Leases (“ASC 842”). As such, the Company assesses all arrangements, that convey the right to control the use of property, plant and equipment, at inception, to determine if it is, or contains, a lease based on the unique facts and circumstances present in that arrangement. For those leases identified, the Company determines the lease classification, recognition, and measurement at the lease commencement date. For arrangements that contain a lease, the Company: (i) identifies lease and non-lease components; (ii) determines the consideration in the contract; (iii) determines whether the lease is an operating or financing lease; and (iv) recognizes lease Right of Use (“ROU”) assets and corresponding lease liabilities. Lease liabilities are recorded based on the present value of lease payments over the expected lease term. The corresponding ROU asset is measured from the initial lease liability, adjusted by (i) accrued or prepaid rents; (ii) remaining unamortized initial direct costs and lease incentives; and (iii) any impairments of the ROU asset.

The Company elected the practical expedient to not separate non-lease components from the lease components. Fixed lease payments on operating leases are recognized over the expected term of the lease on a straight-line basis. Variable lease expenses that are not considered fixed are expensed as incurred. Fixed and variable lease expense on operating leases is recognized within operating expenses within the condensed consolidated statements of operations. The Company has elected the short-term lease exemption and, therefore, does not recognize an ROU asset or corresponding liability for lease arrangements with an original term of 12 months or less.

The interest rate implicit in the Company’s lease contracts is typically not readily determinable and as such, the Company uses its incremental borrowing rate based on the information available at the lease commencement date, which represents an internally developed rate that would be incurred to borrow, on a collateralized basis, over a similar term, an amount equal to the lease payments in a similar economic environment.

Impairment of Long-Lived Assets

Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized for an amount by which the carrying amount of the asset exceeds the fair value of the asset.

The Company did not identify indicators of impairment for the long-lived assets during the three months ended March 31, 2026.

Fair Value Measurements and Fair Value of Financial Instruments

The Company determines fair value, per ASC 820, based on assumptions that market participants would use in pricing an asset or liability in the principal or most advantageous market. When considering market participant assumptions in fair value measurements, the following fair value hierarchy distinguishes between observable and unobservable inputs, which are categorized in one of the following levels:

•Level 1 Inputs are unadjusted quoted prices in active markets for identical assets or liabilities available at the measurement date.

•Level 2 Inputs are unadjusted quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, inputs other than quoted prices that are observable, and inputs derived from or corroborated by observable market data.

•Level 3 Inputs are unobservable inputs which reflect the reporting entity’s own assumptions on what assumptions the market participants would use in pricing the asset or liability based on the best available information.

Revenue Recognition

Pursuant to ASC 606, Revenue from Contracts with Customers (“ASC 606”), the Company recognizes revenue when a customer obtains control of promised goods or services. Revenue is recognized in an amount that reflects the consideration that the Company expects to receive in exchange for those goods or services. 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 performance obligations in the contract; and (v) recognize revenue when (or as) a performance obligation is satisfied.

Net Product Revenues

The Company sells ZELSUVMI to national and regional wholesalers in the United States. The wholesalers are considered the Company’s customers for accounting purposes.

Revenue from product sales is recognized when the customer obtains control of the Company’s product, which typically occurs on delivery. Revenue from product sales is recorded at the transaction price, net of estimates for variable consideration consisting of prompt-pay discounts, distribution service fees, government rebates, co-payment assistance and payor rebates and administration fees for which reserves are established. These reserves are based on estimates of the amounts earned or to be claimed on the related sales and are classified as reductions of accounts receivable (if the amount is payable to the customer) or a liability (if the amount is payable to a party other than the customer).

Variable consideration is estimated using the expected-value amount method, which is the sum of probability-weighted amounts in a range of possible consideration amounts. In making these estimates, the Company considers historical data, including patient mix and inventory sold to customers that has not yet been dispensed. Actual amounts of consideration ultimately received may differ from the Company’s estimates. If actual results vary materially from the Company’s estimates, the Company will adjust these estimates, which will affect net product sales and earnings in the period such estimates are adjusted. These items, as applicable based on current contractual agreements and obligations on behalf of the Company, include:

•Prompt-Pay Discounts — The Company generally provides discounts on product sales to its customers for prompt payment. The Company estimates that its customers will earn these discounts. These discounts are recorded as a reduction of gross revenue and accounts receivable at the time such revenue is recognized.

•Distribution Service Fees — The Company pays certain distribution service fees, such as fees for certain data that customers provide to the Company or for distribution services provided to the Company. Fees paid to its customers are recorded as a reduction of gross revenue and accounts receivable, unless the payment is: (i) for a distinct good or service from the customer; and (ii) the Company can reasonably estimate the fair value of the goods or services received. If both conditions are met, the Company records the consideration paid to the customer as selling, general and administrative expense.

•Co-payment Assistance — Co-payment assistance represents financial assistance to qualified patients, assisting them with prescription drug co-payments required by insurance. The program is administered by a third-party on the Company's behalf. Co-payment assistance is recorded as a reduction of revenue and a current liability is established and included in accrued expenses at the time such revenue is recognized.

•Government Rebates — The Company estimates government rebates, primarily Medicaid, based upon a range of possible outcomes for the estimated patient mix. Medicaid rebates relate to the Company's estimated obligations to states under reimbursement arrangements. Rebates are recorded as a reduction of gross revenue and a current liability is established and included in accrued expenses at the time such gross revenue is recognized. The amount of the rebate for each unit of product reimbursed by the state Medicaid program is established by law and is adjusted upward if the wholesale acquisition cost increases more than inflation (measured by the Consumer Price Index). The liability for Medicaid rebates consists of: (i) estimated current quarter claims; (ii) estimated prior quarter claims for which an invoice has not been received; (iii) prior quarter claims based on unpaid invoices received; and (iv) estimated claims for inventory in the distribution channel at period end.

•Payor Rebates and Administration Fees — Payor rebates and administration fees represent the estimated obligations to third parties, primarily benefit managers. The payor rebates and administration fees result from formulary position, price increase limit allowances (price protection) and administration fees. The liability payor rebates and administration fees are based on the estimated payors buying patterns and the resulting applicable contractual rebate rate(s) to be earned over a contractual period. Payor rebates and administration fees are recorded as a reduction of revenue and a liability is established and included in accrued expenses at the time such revenue is recognized.

License and Collaboration Revenues

The Company has one agreement related to an out-license of intellectual property to a third party. Per ASC 606, the Company determines if there are distinct performance obligations identified in the arrangement. The Company recognizes revenues from non-refundable, upfront fees allocated to the license when the license is transferred to the customer and the customer is able to use and benefit from the license. For licenses that are bundled with other promises, the Company’s management utilizes judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the estimated performance period and the appropriate method of measuring progress during the performance period for purposes of recognizing revenue.

The Company re-evaluates the estimated performance period and measure of progress each reporting period and, if necessary, adjusts related revenue recognition accordingly. These arrangements often include milestone as well as royalty or profit-share payments, contingent upon the occurrence of certain future events linked to the success of the asset in development, as well as expense reimbursements from or payments to the collaboration partner. Because of the risk that products in development will not receive regulatory approval, the Company does not recognize any contingent payments until regulatory approval becomes probable. Future sales-based royalties are not recorded until the subsequent sale occurs.

Cost of Goods Sold

Cost of goods sold includes direct and indirect costs related to the manufacture, production, packaging, and distribution of the Company’s commercial products. These costs primarily consist of manufacturing costs, including allocated overhead, supply costs, third-party logistics and distribution expenses, quality control and assurance costs, and freight and shipping charges incurred in fulfilling customer orders.

Additionally, the Company’s product is subject to strict quality control and monitoring that is performed throughout the manufacturing process, including release of work-in-process to finished goods. In the event that certain batches or units of product do not meet quality specifications, the Company records a write-down of any potential unmarketable inventory to its estimated net realizable value.

As part of the Merger, certain inventoried items were revalued subject to ASC 805. See Note 4 — “Acquisition of LNHC, Inc.” for additional detail.

The amount of expense related to inventory write down as a result of excess, obsolescence, scrap, or other reasons is recorded as cost of goods sold in the condensed consolidated statements of operations.

Selling, General and Administrative Expense

Selling, general and administrative (“SG&A”) expense consists of personnel and non-personnel expenses to support growing sales of ZELSUVMI. Personnel-related expenses include salaries, incentive pay, benefits and share-based compensation for personnel engaged in sales, marketing, regulatory, quality, medical, non-capitalizable manufacturing, finance, information technology and administrative functions. As the majority of the Company’s contracts are short-term in nature, sales commissions are generally recorded as selling, general and administrative expense when incurred as the amortization period would have been less than one year.

Non-personnel-related expense includes: (i) selling, patient services, pharmacovigilance, marketing, advertising, travel, sponsorships and trade shows; and (ii) other general and administrative costs, including consulting, legal, patent, insurance, accounting, information technology and facilities.

The Company uses a third-party logistics provider (“3PL”) to perform a full order-to-cash service, which includes warehousing and shipping directly to its customers on its behalf. Activities performed by the 3PL are recorded in SG&A. SG&A expenses are recognized as they are incurred.

Royalty and/or milestone payments due to third parties under license arrangements for commercial products are expensed within SG&A and recorded as a current liability in the periods in which the obligation is incurred.

Research and Development Expense

Research and development (“R&D”) expense consists of personnel and non-personnel expenses. Personnel-related expense includes salaries, bonus, benefits and share-based compensation for personnel engaged in research and development functions. Non-personnel-related expense includes subcontractors and materials used for R&D activities, development, clinical trials, clinical supply and distribution, and other professional services.

R&D expenses are recognized as they are incurred based on actual work completed through monitoring invoices received and discussions with internal personnel and external service providers as to the progress or stage of completion of preclinical activities, clinical studies and related supporting services for non-commercial assets.

Contingent milestone payments due to third parties under R&D arrangements or license agreements, are expensed within R&D and recorded as a current liability in the periods in which the obligation is incurred.

Stock-Based Compensation

The Company accounts for stock-based compensation costs under the provisions of ASC 718, Compensation—Stock Compensation (“ASC 718”), which requires the measurement and recognition of compensation expense related to the fair value of stock-based compensation awards that are ultimately expected to vest. Stock-based compensation expense recognized includes the compensation cost for all stock-based payments granted to employees, officers, and directors based on the grant date fair value estimated in accordance with the provisions of ASC 718. ASC 718 is also applied to awards modified, repurchased, or cancelled during the periods reported. Stock-based compensation is recognized as expense over the employee’s requisite vesting period and over the non-employee’s period of providing goods or services.

Basic and Diluted Net Loss per Common Share

Basic loss per common share is computed by dividing the net loss by the weighted average number of shares of Common Stock outstanding for each year. Diluted loss per share is computed by dividing the net loss by the weighted average number of shares of Common Stock outstanding plus the dilutive effect of shares issuable through the common stock equivalents. The weighted-average number of common shares outstanding excludes common stock equivalents because their inclusion would be anti-dilutive.

Income Taxes

The Company accounts for income taxes pursuant to the provision of ASC 740 “Accounting for Income Taxes,” (“ASC 740”) which requires, among other things, an asset and liability approach to calculating deferred income taxes. The asset and liability approach requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities. A valuation allowance is provided to offset any net deferred tax assets for which management believes it is more likely than not that the net deferred asset will not be realized.

The Company follows the provision of the ASC 740 related to Accounting for Uncertain Income Tax Positions. When tax returns are filed, it is more likely than not 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. In accordance with the guidance of ASC 740, the benefit of a tax position is recognized in the condensed consolidated 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 measured as the largest amount of tax benefit that is more than 50% likely of being realized upon settlement with the applicable taxing authority. The portion of the benefits associated with tax positions taken that exceeds the amount measured as described above should be reflected as a liability for uncertain tax benefits in the accompanying condensed consolidated balance sheet along with any associated interest and penalties that would be payable to the taxing authorities upon examination. The Company believes its tax

positions will more likely than not be upheld upon examination. As such, the Company has not recorded a liability for uncertain tax benefits.

The federal and state income tax returns of the Company are subject to examination by the Internal Revenue Service and state taxing authorities, generally for three years after they were filed.

Segment Information

Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the Company’s Chief Executive Officer, the chief operating decision-maker (“CODM”). For accounting purposes, the CODM is making decisions regarding resource allocation and assessing performance based on consolidated net loss as if presented in the Company’s condensed consolidated financial statements. The Company views its operations and manages its business in two operating segments, the Commercial Operations segment, and the Research and Development Operations segment.

Related Party Transactions

The Company has historically separately presented certain related party transactions and balances in its condensed consolidated financial statements.

Recently Issued Accounting Pronouncements

In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires disaggregated information about a reporting entity’s effective tax rate reconciliation, as well as information related to income taxes paid to enhance the transparency and decision usefulness of income tax disclosures. This ASU will be effective for the annual periods beginning after December 15, 2024. The Company has adopted ASU 2023-09 for the year-ended December 31, 2025.

In November 2024, the FASB issued ASU No. 2024-03, “Disaggregation of Income Statement Expenses,” which requires disclosures of certain disaggregated income statement expense captions into specified categories within the footnotes to the financial statements. The requirements of the ASU are effective for annual periods beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027, with early adoption permitted.
