Summary of Significant Accounting Policies

The unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and on a basis consistent with the annual consolidated financial statements, and in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary for a fair presentation of the periods presented. These interim financial results are not necessarily indicative of the results to be expected for the year ending December 31, 2026, or for any other future annual or interim period. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in the Annual Report on Form 10-K for the year ended December 31, 2025. The condensed consolidated balance sheet at December 31, 2025, has been derived from the audited consolidated financial statements at that date but does not include all disclosures, including notes, required by U.S. GAAP for complete financial statements.

There has been no material change to the Company's significant accounting policies during the three months ended March 31, 2026, as compared to the significant accounting policies described in Note 2 of the “Notes to Condensed Consolidated Financial Statements” in the Company's Annual Report on Form 10-K as of and for the year ended December 31, 2025, which was filed with the Securities and Exchange Commission (“SEC”) on April 7, 2026.

Except as noted above, the unaudited condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements and, in the opinion of management, reflect all adjustments of a normal recurring nature considered necessary to present fairly the financial position as of March 31, 2026, results of operations for the three months ended March 31, 2026 and 2025, changes in stockholders' deficit for the three months ended March 31, 2026 and 2025, and cash flows for the three months ended March 31, 2026 and 2025. The interim results are not necessarily indicative of the results for any future interim periods or for the entire year.

Principles of Consolidation

The consolidated financial statements have been prepared in accordance with US GAAP and applicable rules and regulations of the SEC. The consolidated financial statements include the accounts of the Company and its subsidiaries in which the Company has a controlling financial interest, including variable interest entities ("VIEs") for which the Company is the primary beneficiary. The Company is considered the primary beneficiary because it has (i) the power to direct the activities that most significantly affect the VIE’s economic performance, and (ii) the obligation to absorb losses of, and the right to receive benefits from, the VIE that could potentially be significant. All intercompany transactions and balances have been eliminated in consolidation. The Company’s reporting currency is the United States ("US") dollar.

Variable Interest Entities

The Company consolidates an entity in which it has a variable interest in accordance with the consolidation guidance in Accounting Standards Codification ("ASC”) 810, Consolidation. JAGX Holdings is a VIE formed to hold cash collateral securing the Company’s obligations under a Secured Promissory Note. The Company has concluded that it is the primary beneficiary of JAGX Holdings, and, accordingly, includes JAGX Holdings in its consolidated financial statements.

Significant Judgments and Determinations

The Company consolidates JAGX Holdings as a VIE because JAGX Holdings lacks sufficient equity at risk to finance its activities independently. The Company is the primary beneficiary as it holds the power to direct JAGX Holdings’ most significant economic activities—primarily the administration of a restricted deposit account—and is exposed to significant residual returns and losses as the sole member and issuer of Streeterville New Note (see Note 7). Lender rights held by Streeterville Capital, LLC (“Streeterville”) were determined to be protective and do not grant the ability to direct JAGX Holdings’ significant activities.

Nature of Restrictions and Financial Position

JAGX Holdings was formed as a bankruptcy‑remote special purpose entity solely to hold the cash collateral securing the Note issued by Jaguar. Its primary asset consists of funds held in a restricted deposit account governed by a DACA, which are not available for Jaguar’s general corporate purposes. Under the terms of the DACA, Jaguar is prohibited from unilaterally withdrawing funds; access is restricted to a formulaic release mechanism contingent upon the repayment of Jaguar’s debt obligations, subject to Streeterville’s right to seize the funds unilaterally upon the occurrence of a trigger event or a determination that repayment is impaired.

As of March 31, 2026, the carrying amount of JAGX Holdings' assets included in the Company’s consolidated financial statements was restricted cash of $2.8 million. The Secured Promissory Note, which is a full‑recourse obligation of Jaguar and is collateralized by the restricted cash held by JAGX Holdings, is presented within Notes Payable in the consolidated balance sheet, with approximately $3.3 million classified as current and the remainder classified as non‑current. A derivative liability related to an embedded feature in the Secured Promissory Note is also recognized within the Company’s consolidated balance sheet.

Risks and Recourse

The Note is a full‑recourse obligation of Jaguar. Streeterville’s rights as a creditor extend beyond the assets held by JAGX Holdings to the general credit of Jaguar. During the period ended March 31, 2026, Jaguar provided no financial or other support to JAGX Holdings beyond what was contractually required under the Note Purchase Agreement dated November 12, 2025.

Effects on Financial Position, Financial Performance, and Cash Flows

Jaguar’s involvement with JAGX Holdings primarily affects its financial position through the recognition of restricted cash, the related current and non‑current portions of notes payable, and the derivative instrument associated with the embedded feature in the Secured Promissory Note within the consolidated balance sheet. The restricted cash is not available for general corporate purposes and is classified accordingly. JAGX Holdings does not conduct operations and therefore does not have a significant direct impact on the Company’s revenues or operating expenses. However, the interest expense on the Secured Promissory Note, changes in the fair value of the related derivative instrument, and interest income earned on the restricted deposit account are recognized in Jaguar’s consolidated statements of operations in the periods incurred. Cash flows between Jaguar and JAGX Holdings are limited to movements of funds into and out of the restricted deposit account in connection with borrowings, repayments of principal and interest on the Note, and any permitted formula‑based releases under the DACA, all of which are reflected within Jaguar’s consolidated statements of cash flows consistent with the underlying nature of the transactions.

Noncontrolling interest

The Company consolidates the results of Napo Therapeutics, which was owned 89% by the Company and 11% by private investors as of March 31, 2026 and December 31, 2025. The potential voting rights with a certainty of being exercised in its shares are included in the ownership percentage.

Use of Estimates

The preparation of the condensed consolidated financial statements in conformity with US GAAP requires the Company’s management to make judgments, assumptions and estimates that affect the amounts reported in its unaudited condensed consolidated financial statements and the accompanying notes. The accounting policies that reflect the Company’s more significant estimates and judgments and that the Company believes are the most critical to aid in fully understanding and evaluating its reported financial results are the valuation of stock options, restricted stock units (“RSUs”), freestanding and hybrid instruments designated at fair value option (“FVO”), warrant liabilities, acquired in-process research and development (“IPR&D”), and useful lives assigned to long-lived assets; impairment assessment of non-financial assets; valuation adjustments for excess and obsolete inventory; allowance for doubtful accounts; deferred taxes and valuation allowances on deferred tax assets; evaluation and measurement of contingencies; and recognition of revenue, including estimates for product returns. Those estimates could change, and as a result, actual results could differ materially from those estimates.

Cash and Restricted Cash

The Company’s cash on deposit may exceed United States federally insured limits at certain times during the year. The Company maintains cash accounts with certain major financial institutions in the United States. Restricted cash represents cash not available to us for immediate and general use. Amounts included in restricted cash primarily relate to funds subject to legal or contractual withdrawal restrictions. The Company does not have cash equivalents as of March 31, 2026 and December 31, 2025.

Accounts Receivable, net

Accounts receivable is recorded net of allowances for discounts for prompt payment and credit losses.

Upon adoption of Accounting Standards Update (“ASU”) No. 2013-13, ASC 326, Financial Instruments—Credit Losses, the Company began utilizing a loss rate approach under the Current Expected Credit Losses (“CECL”) model to determine its lifetime expected credit losses on receivables from customers. This method calculates an estimate of credit losses based on historical experience, credit quality, age of the accounts receivable balances, and current and forecasted economic and business conditions that may affect a customer’s ability to pay. In determining the loss rates, the Company evaluates information related to its historical losses,

adjusted for existing conditions, and further adjusted for the period of time that can reasonably be forecasted. The facts and circumstances as of the balance sheet date are used to adjust the estimate for periods beyond those that can reasonably be forecasted.

The past due status of accounts receivable is determined based on the contractual due dates for payments. Receivable is deemed past due when payment has not been received 30 days after the contractual due date. The credit loss allowance was immaterial as of March 31, 2026 and December 31, 2025. The corresponding expense for the credit loss allowance is reflected in general and administrative expenses.

Current Expected Credit Losses

The Company recognizes an allowance for credit losses for financial assets carried at amortized cost to present the net amount expected to be collected as of the balance sheet date. Such allowance is based on credit losses that are expected to arise over the contractual term of the asset, which includes consideration of historical credit loss information adjusted for current conditions and reasonable and supportable forecasts.

Changes in the allowance for credit losses are recorded as provision of (or reversal of) credit loss expense. Assets are written off when the Company determines that such are deemed uncollectible. Write-offs are recognized as a deduction from the allowance for credit losses. Expected recoveries of amounts previously written off, not to exceed the aggregate of the amount previously written off, are included in determining the necessary allowance at the balance sheet date.

Concentrations

Cash is the financial instrument that potentially subjects the Company to a concentration of credit risk as cash is deposited with a bank and cash balances generally exceed Federal Deposit Insurance Corporation (“FDIC”) insurance limits.

For the three months ended March 31, 2026, approximately 98% of the Company’s revenue was derived from license revenue with Woodward.

For the three months ended March 31, 2025, substantially all of the Company’s revenue was derived from the sale of Mytesi. In looking at sales by the Company to specialty pharmacies whose net revenue percentage of total net revenue was equal to or greater than 10% for fiscal years 2026 and 2025, the Company earned Mytesi revenue primarily from two specialty pharmacies located in the United States. Revenue earned from each major customer as a percentage of total revenue is as follows:


	Three Months Ended
	March 31,
	2026			2025
Customer 1		98	%		0	%
Customer 2		1	%		61	%
Customer 3		0	%		22	%

The Company is subject to credit risk from its accounts receivable related to its sales. Accounts receivable balance of the significant customers as a percentage of total accounts receivable is as follows:


	March 31,			December 31,
	2026			2025
Customer 1		48	%		2	%
Customer 2		39	%		46	%
Customer 3		0	%		39	%

The Company is subject to concentration risk from its accounts payable related to its cost of product revenue. Accounts payable balance of the significant suppliers as a percentage of total accounts payable is as follows:


	Three Months Ended
	March 31,
	2026			2025
Supplier 1		23	%		17	%
Supplier 2		14	%		8	%
Supplier 3		9	%		14	%

The cost of product revenue balance of the significant suppliers as a percentage of total cost of product revenue is as follows:


	Three Months Ended
	March 31,
	2026	2025
Supplier 1	53%	0%
Supplier 2	4%	11%
Supplier 3	0%	18%
Supplier 4	0%	50%

Other Risks and Uncertainties

The Company’s future operations results involve a number of risks and uncertainties. Factors that could affect the Company’s future operating results and cause actual results to vary materially from expectations including, but not limited to, war, rapid technological change, obtaining second source suppliers and manufacturers, regulatory approval from the US Food and Drug Administration (“FDA”) or other regulatory authorities, the results of clinical trials and the achievement of milestones, market acceptance of the Company’s product candidates, competition from other products and larger companies, protection of proprietary technology, strategic relationships, and dependence on key individuals. In addition, the reshaping of the federal government workforce may impact the availability, timing, and consistency of regulatory oversight and funding, introducing further uncertainty to the Company’s operations.

Other Global Events

Macroeconomic conditions worldwide are subject to constant change, influenced by several factors, including persistently high inflation, structural weaknesses in the labor market, low productivity growth, adverse weather conditions, and possible political unrest in certain regions. Despite these global economic challenges, no significant changes have occurred in the Company's operations.

Fair Value

The Company’s financial instruments include accounts receivable, net, other receivable, derivative liability, accounts payable, accrued liabilities, operating lease liability, derivative liability, and debt. The recorded carrying amount of accounts receivable, other receivable, accounts payable, and accrued liabilities reflect their fair value due to their short-term nature. Other financial liabilities are initially recorded at fair value, and subsequently measured at fair value or amortized cost using the effective interest method. See Note 3 for the fair value measurements.

Fair Value Option

ASC 825-10, Financial Instruments (“ASC 825-10”), provides an FVO election that allows companies an irrevocable election to use fair value as the initial and subsequent accounting measurement attribute for certain financial assets and liabilities. ASC 825-10 permits entities to elect to measure eligible financial assets and liabilities at fair value on an ongoing basis. Unrealized gains and losses on items for which the FVO has been elected are reported in earnings. The decision to elect the FVO is determined on an instrument-by-instrument basis, must be applied to an entire instrument and is irrevocable once elected. Assets and liabilities measured at fair value pursuant to ASC 825-10 are required to be reported separately from those instruments measured using another accounting method. In accordance with the options presented in ASC 825-10, the Company elected to present the aggregate of fair value and non-fair-value amounts in the same line item in the condensed consolidated balance sheets and parenthetically disclose the amount measured at fair value in the aggregate amount. The fair values of the Company's financial instruments reflect the amounts 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 (exit price). The fair value estimates presented in these financial statements are based on information available to the Company as of March 31, 2026 and December 31, 2025.

Derivative Instrument

The Company evaluates its financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives. For derivative instruments that are bifurcated from a host contract, the Company recognizes them as either assets or liabilities in the consolidated balance sheet and measures them at fair value. Embedded derivatives are bifurcated from the host contract when their economic characteristics and risks are not clearly and closely related to the host contract, the hybrid instrument is not measured at fair value with changes in fair value reported in earnings, and the embedded feature would meet the definition of a derivative if it were a freestanding instrument. These derivatives are remeasured at each reporting date, with changes in fair value recognized in earnings within other income (expense), net in the consolidated statement of operations.

Inventory, net

Inventory is stated at the lower of cost or net realizable value. Cost is determined using the first-in, first-out method. Cost is initially recorded at the invoiced amount of services or crude plant latex (“CPL”) provided by third-party processors, Probos L&CH ("Probos") and Corporación Forestal Amazónico ("CORFA SAC"), including the sum of qualified expenditures and charges for bringing the inventory to its existing condition and location. Inventory is categorized into raw materials, work-in-process, and finished goods. Raw materials consist of CPL, recognized as inventory upon harvest and valued at cost, including acquisition and harvest expenditures. Work-in-process inventory is recognized only when CPL has been transformed into Active Pharmaceutical Ingredient (“API”) and is in transit to Patheon Pharmaceuticals Inc., with costs comprising direct materials, labor, and applicable overheads. Finished goods represent completed crofelemer tablets ready for sale, valued at cost, which includes direct materials, labor, and manufacturing overhead allocated during production. The Company calculates inventory valuation adjustments when conditions indicate that net realizable value is less than cost due to physical deterioration, usage, obsolescence, reductions in estimated future demand, or reductions in selling price. Inventory write-downs are measured as the difference between the cost of inventory and net realizable value. Inventory costs are removed from inventory and recorded in the cost of goods sold upon delivery of the tablets to customers.

Prelaunch Inventory

The Company’s policy is to capitalize costs for prelaunch inventories within the drug development phase, which is evidence that the product’s reasonably likely critical attributes for success are present and feasible, and the key causes of failures are absent based on management’s assumptions. The costs that can be capitalized for prelaunch inventory are recorded as “Prepaid expenses and other current assets.”

Property and Equipment

Land is stated at cost, reflecting the fair value of the property at July 31, 2017, the date of the Napo merger. Equipment is stated at cost, net of accumulated depreciation. Equipment begins to be depreciated when it is placed into service. Depreciation is calculated using the straight-line method over estimated useful lives ranging from three to ten years.

Expenditures for repairs and maintenance of assets are charged to expenses as incurred. Costs of major additions and betterments are capitalized and depreciated on a straight-line basis over their estimated useful lives. Upon retirement or sale, the cost and related accumulated depreciation of assets disposed of are removed from the accounts and any resulting gain or loss is included in the unaudited condensed consolidated statement of operations.

Software Developed for Internal Use

The Company capitalizes the costs of developing software for internal use. These costs include both purchased software and internally developed software. Costs of developing software are expensed until technological feasibility has been established. Thereafter, all costs are capitalized and are carried at the lower of unamortized cost or net realizable value. Internally developed and purchased software costs are generally amortized over five years.

Long-lived Assets

The Company regularly reviews the carrying value and estimated lives of all of its long-lived assets, including property and equipment and definite-lived intangible assets, to determine whether indicators of impairment exist that warrant adjustments to carrying values or estimated useful lives. The determinants used for this evaluation include management’s estimate of the asset’s ability to generate positive income from operations and positive cash flow in future periods, as well as the strategic significance of the assets to the Company’s business objectives. If the Company determines that events or changes in circumstances indicate that the carrying amount of the asset group may not be recoverable, the Company evaluates the realizability of its long-lived assets (asset group) based on a comparison of projected undiscounted cash flows from use and eventual disposition with the carrying value of the related asset. Any write-downs (measured based on the difference between the fair value and the asset's carrying value) are treated as permanent reductions in the carrying amount of the assets (asset group).

None of the Company’s long-lived assets were deemed impaired as of March 31, 2026 and December 31, 2025.

Indefinite-lived Intangible Assets

Acquired IPR&D are intangible assets acquired in the July 2017 Napo merger. Under ASC 805, Business Combination, IPR&D are initially recognized at fair value and classified as indefinite-lived assets until the successful completion or abandonment of

the associated research and development efforts. During the development period, these assets will not be amortized as charges to earnings; instead, these assets will be tested for impairment on an annual basis or more frequently if impairment indicators are identified. An impairment loss is measured based on the excess of the carrying amount over the asset’s fair value.

Leases

The Company accounts for its leases in accordance with ASC 842, Leases (“ASC 842”).

At the inception of an arrangement, the Company determines whether the arrangement is or contains a lease based on the unique facts and circumstances present. Operating lease liabilities and their corresponding right-of-use assets are recorded based on the present value of lease payments over the expected lease term. Because the interest rate implicit in lease contracts is typically not readily determinable, the Company utilizes its incremental borrowing rate, which is the rate incurred to borrow on a collateralized basis over a similar term, an amount equal to the lease payments in a similar economic environment. Certain adjustments to the right-of-use asset may be required for items such as initial direct costs paid or incentives received.

The Company elected to include both the lease and non-lease components as a single component and account for its lease.

Lease Modification

ASC 842 defines lease modification as a change to the terms and conditions of a contract that results in a change in the scope of or the consideration for a lease. A lease modification can result in either a separate new contract that is accounted for separately from the original contract or a single modified contract.

The Company accounts for a modification to a contract as a separate contract when the modification grants the lessee an additional right of use not included in the original lease and the lease payments increase commensurate with the standalone price for the additional right of use, adjusted for the circumstances of the particular contract. When the Company concludes that a lease modification should be accounted for as a new contract that is separate and apart from the original lease, the new contract should be evaluated for whether it is a lease or contains an embedded lease. If the new contract is a lease or contains an embedded lease, the new lease should be accounted for as any other new lease. The new lease is recorded on the commencement date of the new lease, which is the date the lessee has access to the leased asset.

If a lease modification is not accounted for as a separate contract, the Company should reassess whether the contract contains a lease. If the modified contract is a lease or contains an embedded lease, a lessee should reallocate contract consideration, reassess the lease classification, remeasure the lease liability, and adjust the right-of-use asset.

Research and Development Expense

Research and development ("R&D") expenses consist of expenses incurred in performing research and development activities, including related salaries, clinical trials, and related drug and non-drug product costs, contract services, and other outside service expenses. Research and development expenses are charged to operating expenses during the period incurred.

The Company capitalizes tangible costs for materials that have a probable alternative future use in other research and development projects. The Company determines that alternative future use exists when materials are not dedicated to a single, specific clinical trial and possess separate economic value independent of any one project's success. These capitalized materials are recorded as "Prepaid expenses and other current assets" based on their expected timing of use. The Company reclassifies these materials as R&D expense when they are consumed in research activities or become specifically dedicated to a clinical trial, at which point the alternative future use is deemed to no longer exist.

Liability-Classified Preferred Stock

The Company evaluates its financial instruments to determine the appropriate classification as liabilities or equity under ASC 480, Distinguishing Liabilities from Equity. Financial instruments issued in the form of shares that embody an unconditional obligation to transfer a variable number of equity shares are classified as liabilities if the monetary value of the obligation is predominantly fixed, varying with something other than the fair value of the issuer’s equity shares, or varying inversely with the fair value of those shares.

On February 18, 2026, the Company declared Series O Convertible Preferred Stock as a one-time special dividend. On March 4, 2026, the Company issued the Series O Convertible Preferred Stock. The Company determined that these shares represent an

unconditional obligation to deliver a variable number of common shares with a monetary value that is predominantly fixed at inception. Accordingly, the Series O Convertible Preferred Stock is classified and accounted for as a liability.

Clinical Trial Accruals

Clinical trial costs are a component of research and development expenses. The Company accrues and expenses for clinical trial activities performed by third parties based upon actual work completed in accordance with agreements established with clinical research organizations and clinical sites. The Company determines the costs to be recorded based upon validation with the external service providers as to the progress or stage of completion of trials or services and the agreed-upon fee to be paid for such services.

Revenue Recognition

The Company recognizes revenue in accordance with ASC 606, Revenue from Contracts with Customers (“ASC 606”).

The Company’s policy typically permits returns if the product is damaged, defective, or otherwise cannot be used when received by the customer if the product has expired. Returns are accepted for products that will expire within three months or that have expired up to one year after their expiration dates. Estimates for expected returns of expired products are based primarily on an ongoing analysis of our historical return patterns.

The Company recognizes revenue in accordance with the core principle of ASC 606 or when there is a transfer of control of promised goods or services to customers in an amount that reflects the consideration that the Company expects to be entitled to in exchange for those goods or services.

The Company recognizes the incremental costs of obtaining a contract as an expense when incurred if the amortization period of the asset that the Company otherwise would have recognized is one year or less.

The Company does not adjust the amount of consideration for the effects of a significant financing component if, at contract inception, the expected period between the transfer of promised goods or services and customer payment is one year or less.

The Company has elected to treat shipping and handling activities as fulfillment costs. Additionally, the Company elected to record revenue net of sales and other similar taxes as "Product revenue, net" in the consolidated statements of operations.

Contracts - Distribution Agreement

The Company's Canalevia-CA1 and Neonorm products are primarily sold to distributors, who then sell the products to end customers. Since 2021, the Company has entered into one distribution agreement with an established distributor to distribute the Company’s animal health products in the United States. The distribution agreement and the related purchase orders together meet the contract existence criteria under ASC 606. The Company sells directly to its customers without the use of an agent.

Performance obligations

For animal health products sold by the Company, the single performance obligation identified above is the Company’s promise to transfer the Company’s animal health products to distributors based on specified payment and shipping terms in the arrangement. Product warranties are assurance-type warranties that do not represent a performance obligation. For the Company’s human health product, Mytesi, the single performance obligation identified above is the Company’s promise to transfer Mytesi to specialty pharmacies based on specified payment and shipping terms as outlined in the Exclusive Distribution Agreement entered into by the Company and Cardinal Health, Inc. ("Cardinal Health") as of January 16, 2019.

Transaction price

For contracts with Cardinal Health and other distributors, the transaction price is the amount of consideration that the Company expects to collect in exchange for transferring the promised goods or services. The transaction price of Mytesi is the Wholesaler Acquisition Cost (“WAC”), and the transaction price of Canalevia-CA1 and Neonorm is the manufacturer’s list price, net of discounts, returns, and price adjustments.

Allocate transaction price

For contracts with distributors, the entire transaction price is allocated to the single performance obligation contained in each contract.

Revenue recognition

For contracts with Cardinal Health, a single performance obligation is satisfied at a point in time upon each contract's Free On Board (“FOB”) terms when control, including title and all risks, has transferred to the customer.

Disaggregation of Product Revenue

Human

Sales of Mytesi are recognized as revenue at a point in time when the products are delivered to the specialty pharmacies. Net revenues from the sale of Mytesi were $918,000 and $2.1 million for the three months ended March 31, 2026 and 2025, respectively.

Animal

The Company recognized Canalevia-CA1 products revenues of $270,000 and $17,000 for the three months ended March 31, 2026 and 2025, respectively. The Company recognized Neonorm revenues of $7,000 and $16,000 for the three months ended March 31, 2026 and 2025, respectively. Revenues are recognized at a point in time upon shipment, when title and control are transferred to the buyer. Sales of Canalevia-CA1, Neonorm Calf and Foal to distributors are made under agreements that may provide distributor price adjustments and rights of return under certain circumstances.

Contracts – Specialty Pharmacies

Effective October 1, 2020, the Company engaged a private company as an authorized specialty pharmacy provider of the Company’s Mytesi product. Under the Specialty Product Distribution Agreement, the Company shall supply the products directly to the private company’s specialty pharmacies in such amounts as may be ordered. There is no minimum purchase or inventory requirement. The specialty pharmacies were authorized distributors of record for all National Drug Codes of Mytesi.

Effective April 20, 2021, the Company engaged another private company as an authorized specialty pharmacy provider of Mytesi. Under the Specialty Pharmacy Distribution and Services Agreement, the private company shall sell and dispense Mytesi directly ordered from the Company at the agreed price to patients within the territories identified in the agreement.

The Company has entered into agreements with a total of five different specialty pharmacy chains that are authorized to provide Mytesi to patients.

Performance obligations

The single performance obligation is the Company’s promise to transfer Mytesi to specialty pharmacies, based on specified payment and shipping terms outlined in the agreements.

Transaction price

The transaction price is the amount of consideration the Company expects to collect in exchange for transferring the promised goods or services. The transaction price of Mytesi is the WAC, net of estimated discounts, returns, and price adjustments.

Allocate transaction price

The entire transaction price is allocated to the single performance obligation contained in each contract.

Revenue recognition

The single performance obligation is satisfied at a point in time, upon the FOB terms of each contract, when control, including title and all risks, has been transferred to the customer.

Product Revenue

Sales of Mytesi are recognized as revenue at a point in time when the products are delivered to the specialty pharmacies. Net revenues from the sale of Mytesi to the specialty pharmacies were $11,000 and $1.7 million for the three months ended March 31, 2026 and 2025, respectively.

Contracts – Exclusive Distribution Agreement

On April 12, 2024, the Company entered into a five-year exclusive in-license agreement with Venture Life Group PLC (“Venture Life”), a United Kingdom-based international consumer health company focused on the global self-care market for Venture Life’s 510(k) cleared oral mucositis prescription product, Gelclair for the US market. The agreement grants the Company the exclusive rights to market Venture Life's FDA-approved oral mucositis prescription product, Gelclair, within the US market. The Company paid a non-refundable license fee of €200,000 (equivalent to $215,040, excluding value-added taxes or "VAT") to Venture Life. Additionally, the Company will pay Venture Life a running royalty based on a percentage of the net sales throughout the agreement term. The non-refundable license fee has been capitalized as license under intangible assets, while the running royalty will be recognized as royalty expense. The agreement and binding term sheet collectively qualify as a valid contract under ASC 606.

Performance obligations

The Company identified a single performance obligation, which is the exclusive rights to market Gelclair in the US market. The Company will pay Venture Life a running royalty based on a percentage of the net sales throughout the agreement term.

Transaction price

Allocate transaction price

The entire transaction price is allocated to the single performance obligation contained in the contract.

Revenue recognition

The single performance obligation is satisfied over-time, throughout the five-year license period.

Product Revenue

For the three months ended March 31, 2026 and 2025, the Company recognized a revenue of $9,000 and $25,000, respectively. For the three months ended March 31, 2026 and 2025, the total royalty expense associated with this contract amounted to $142,000 and $39,000, respectively. The royalty expense are recorded as "Cost of product revenue" in the consolidated statements of operations.

Contracts – License Agreement

Effective March 18, 2024, the Company engaged in a securities purchase agreement, supplemented by a binding term sheet, with Gen Ilac Ve Saglik Urunleri Sanayi Ve Ticaret, A.S. (“GEN” or “Licensee”). The Company grants GEN a right to access its intellectual property for the Company's FDA-approved prescription drug crofelemer and commercialize crofelemer finished product in licensed Eastern Europe territories for a consideration including license fees, royalties and product sales. The agreement and binding term sheet collectively qualifies as a valid contract under ASC 606.

Performance obligations

The Company identified two promises, namely (1) the grant of license to manufacture and commercialize pharmaceutical products that utilize Crofelemer (the “Licensing Transaction”) and (2) the supply of crofelemer API. Licensee cannot benefit from the license alone without the API as the latter comes from a plant exclusive to the Company. No other entities can produce the API. Consequently, the grant of license and the supply API are not distinct, and accounted as a single performance obligation.

Transaction price

Transaction price is the amount of consideration to which an entity expects to be entitled in exchange for transferring promised goods or services to a customer, excluding amounts collected on behalf of third parties. The transaction price in the contract with GEN includes both fixed and variable considerations.

For the Licensing Transaction, the fixed consideration is measured as the difference between the proceeds from the related share issuance and the fair value of the shares issued. The variable consideration, in the form of royalty, is based on a percentage of

the Licensee's revenue from the sale of pharmaceutical products utilizing Crofelemer. For the supply of Crofelemer API, the variable consideration is determined using the expected value of a wide range of possible amounts.

Allocate transaction price

The entire transaction price is allocated to the single performance obligation contained in the contract.

Revenue recognition

The single performance obligation is satisfied over-time, throughout the five-year license period, based on the expiration dates of the licensed patents.

License Revenue

For the three months ended March 31, 2026 and 2025, license fees recognized from the contract with GEN amounted to $43,000 and $43,000, respectively. As of March 31, 2026 and December 31, 2025, the total deferred revenue associated with this contract amounted to $510,000 and $552,000, respectively.

Contracts – License and Supply Agreement

Effective January 12, 2026 (the "Effective Date"), the Company engaged in a license and supply agreement with Woodward, an affiliate of Future Pak, LLC (“Future Pak”), and Future Pak, pursuant to which, Napo granted to Woodward an exclusive, nontransferable, sublicensable, royalty-free right and license under the Napo Mytesi Patents to sell, offer for sale, have sold, make, have made, promote, distribute and otherwise commercialize the Mytesi Product and the Canalevia Product. The agreement and binding term sheet collectively qualifies as a valid contract under ASC 606.

Performance obligations

The Company identified three promises, namely (1) the grant of the exclusive intellectual property (“IP”) license, (2) manufacturing and supply of the Mytesi Product and the Canalevia Product (the “Products”), and (3) the transfer of existing inventory of the Products on the Effective Date (the "Effective Date Inventory"). The manufacturing process for these products is not proprietary to Napo’s internal operations and is currently performed by third-party contract manufacturing organizations, and can benefit from the license using readily available resources. Consequently, the grant of exclusive IP license, the manufacturing and supply of the Products, and the transfer of Effective Date Inventory are distinct, and accounted as separate performance obligations.

Significant judgments

The Company exercised significant judgment in determining that the Mytesi patents constitute functional intellectual property rather than symbolic intellectual property. This determination was based on the fact that the Mytesi patents possess significant standalone functionality, and the Company’s ongoing activities do not significantly change that functionality or the utility of the intellectual property to Woodward. Consequently, the license provides a right to use the intellectual property as it exists at a point in time.

Transaction price

For the exclusive IP license, the fixed consideration is the upfront payment for the grant of the exclusive IP license. The variable considerations, in the form of contingent payments, are based on the amount of consideration indicated in the contract upon satisfaction of conditions and sales milestones. For the supply of manufacturing and supply of the Products and transfer of Effective Date Inventory, the variable consideration is determined using the expected value of a wide range of possible amounts.

As of March 31, 2026, the Company performed a specific probability assessment of these milestones. Due to the inherent uncertainty of pharmaceutical commercialization and the dependence on third-party performance, the Company determined that these milestones are fully constrained. Therefore, they are excluded from the transaction price as it is not yet highly probable that a significant reversal of cumulative revenue will not occur.

Allocate transaction price

The transaction price is allocated to the distinct performance obligations based on their relative standalone selling prices at contract inception. Variable consideration related to sales milestones is allocated entirely to the exclusive IP license once the constraint is removed.

Revenue recognition

At inception, the exclusive IP license was accounted for as a financing arrangement under ASC 606-10-55-66, as the Company retained a call option to reacquire the commercial rights for an amount exactly equal to the original consideration. Because the repurchase price was equal to the consideration received, the specific accretion of interest during the period the option remained outstanding was zero. On February 22, 2026, Napo received a $3.0 million fee to extinguish the clause. Upon extinguishment, control of the exclusive IP license was transferred to Woodward. Revenue for the exclusive IP license is recognized at a point in time upon the transfer of control.

Revenue for supply services and inventory is recognized at a point in time upon delivery and customer acceptance.

Capital structure and Nasdaq compliance

The timing and recognition of the $19.0 million in license revenue directly influenced the Company’s broader capital structure initiatives. The resulting increase in stockholders' equity (deficit) was fundamental in restoring the Company to compliance with the Nasdaq minimum equity listing requirements.

License Revenue

For the three months ended March 31, 2026, license fees recognized from the contract with Woodward amounted to $19.0 million. As of March 31, 2026, the total financial liability associated with this contract amounted to $0.

Collaboration Revenue

Revenue recognition for collaboration agreements requires significant judgment. The Company’s assessments and estimates are based on contractual terms, historical experience, and general industry practice. Revisions in these values or estimations increase or decrease collaboration revenue in the period of revision.

On September 24, 2018, the Company entered into a Distribution, License, and Supply Agreement (“License Agreement”) with Knight Therapeutics (“Knight”). The License Agreement has a term of 15 years (with automatic renewals) and provides Knight with an exclusive right to commercialize current and future Jaguar human health products (including crofelemer, NP-300, and any product containing a proanthocyanidin or with an anti-secretory mechanism) in Canada and Israel. Knight forfeited its right of first negotiation for expansion to Latin America. Under the License Agreement, Knight is responsible for applying for and obtaining necessary regulatory approvals in the territory of Canada and Israel, as well as marketing, sales, and distribution of the licensed products. Knight will pay a transfer price for all licensed products, and upon achievement of certain regulatory and sales milestones, the Company may receive payments from Knight in an aggregate amount of up to approximately $18.0 million, payable throughout the initial 15-year term of the agreement. The Company did not have any license revenues for the three months ended March 31, 2026 and 2025.

Modifications to Liability-classified Instruments

In accounting for debt modifications and exchange transactions, it is the Company’s policy first to determine whether it qualifies as a troubled debt restructuring (“TDR”) pursuant to the guidance provided in ASC 470-60, Debt—Troubled Debt Restructurings by Debtors (“ASC 470-60”). A debt modification or exchange transaction that is not within the scope of the ASC 470-60 is accounted for under ASC 470-50, Modification and Extinguishments (“ASC 470-50”), to determine if the transaction is a mere modification or an extinguishment.

For the three months ended March 31, 2026 and March 31, 2025, the Company has entered into amendments to the terms of its royalty interests and purchase agreements. The cumulative impact of these amendments resulted in certain extinguishments and modifications (See Note 7).

Modifications to Equity-classified Instruments

In accounting for modifications of equity-classified warrants, the Company’s policy is to determine the impact by analogy to the share-based compensation guidance of ASC 718, Compensation-Stock Compensation (“ASC 718”). The model for a modified share-based payment award that is classified as equity and remains classified in equity after the modification is addressed in ASC 718-20-35-3, Compensation-Stock Compensation—Awards Classified as Equity—Subsequent Measurement. Pursuant to that guidance, the incremental fair value from the modification is recognized as an expense in the statements of operations to the extent the modified instrument has a higher fair value; however, in certain circumstances, such as when an entire class of warrants is modified, the measured increase in fair value may be more appropriately recorded as a deemed dividend, depending upon the nature of the warrant modification.

The Company did not modify any equity-classified warrants for the three months ended March 31, 2026 and 2025.

In accounting for amendments to preferred stock, the Company’s policy is to measure the impact by analogy to ASC 470-50 in determining if such an amendment is an extinguishment or a modification. If the amendment results in an extinguishment, the Company follows the SEC staff guidance in ASC 260-10-S99-2, Earnings Per Share—Overall—SEC Materials, and ASC 470-20, Debt—Debt with Conversion and Other Options. If the amendment results in a modification, the Company follows the model in either ASC 718 or ASC 470-50, depending on the nature of the amendment.

The Company did not modify any equity-classified preferred stock for the three months ended March 31, 2026 and 2025.

Stock-based Compensation

The Company's Stock Incentive Plan (See Note 12) provides for the grant of stock options, restricted stock, and restricted stock unit awards. The Company measures stock awards granted to employees, non-employees, and directors at estimated fair value on the date of grant and recognizes the corresponding compensation expense of the awards, net of estimated forfeitures, over the requisite service periods, which correspond to the vesting periods of the awards. If necessary, forfeitures are estimated at the time of grant and revised in subsequent periods if actual forfeitures differ from those estimates. The Company issues stock awards with only service-based vesting conditions and records compensation expenses for these awards using the straight-line method.

The Company uses its common stock's grant date fair market value to determine the grant date fair value of options granted to employees, non-employees, and directors. The Company measures and recognizes compensation expense for all stock options and RSUs granted to its employees and directors based on the estimated fair value of the award on the grant date. The Company believes that the fair value of stock options granted to non-employees is more reliably measured than the fair value of the services received. The determination of the grant date fair value of options using an option pricing model is affected by the Company’s estimated common stock fair value and requires management to make a number of assumptions, including the expected life of the option, the volatility of the underlying stock, the risk-free interest rate and expected dividends.

The Company estimates the fair value of stock options using the Black-Scholes option valuation model. The fair value is recognized as an expense, net of estimated forfeitures, over the requisite service period, which is generally the vesting period of the respective award, on a straight-line basis. The fair market value of common stock is based on the closing price of the Company’s common stock as reported on the date of the grant.

Income Taxes

The Company uses the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial reporting and the tax bases of assets and liabilities and are

measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. A valuation allowance is provided when it is more likely than not that some portion or all of a deferred tax asset will not be realized.

The Company has adopted the provisions of ASC 740, Income Taxes. Under these principles, tax positions are evaluated in a two-step process. The Company first determines whether it is more likely than not that a tax position will be sustained upon examination. If a tax position meets the more-likely-than-not recognition threshold, it is then measured to determine the amount of benefit to be recognized in the financial statements. The tax position is the most significant benefit, with a greater than 50 percent likelihood of being realized upon ultimate settlement.

The Company files a consolidated tax return for its related entities.

Foreign Currency Remeasurement and Translation

The functional currency of Napo Therapeutics is the Euro. The Company follows ASC 830, Foreign Currency Matters (“ASC 830”). ASC 830 requires the assets, liabilities, and results of operations of a foreign operation to be measured using the functional currency of that foreign operation. Exchange gains or losses from remeasuring transactions and monetary accounts in a currency other than the functional currency are included in current earnings or losses.

Translation adjustments result from translating the functional currency of subsidiary financial statements into the US Dollar reporting currency. These translation adjustments are reported separately and accumulated in the consolidated balance sheets as a component of accumulated other comprehensive gain or loss.

Comprehensive Gain or Loss

The Company follows ASC 220, Income Statement—Reporting Comprehensive Income, which establishes standards for reporting and displaying comprehensive income and its components (revenue, expenses, gains, and losses) in a full set of general-purpose financial statements.

For the three months ended March 31, 2026 and 2025, the amount of other comprehensive income from translation adjustments were $458,000 and $262,000, respectively.

Basic and Diluted Net Loss Per Share of Common Stock

Basic net loss per share of common stock is computed by dividing net loss attributable to common stockholders for the year by the weighted average number of common stock outstanding during the year. Diluted net loss per share is computed by dividing the net loss attributable to common stockholders for the year by the weighted average number of common stock, including potential dilutive shares of common stock assuming the dilutive effect of potential dilutive securities. The Company uses the treasury stock method to calculate diluted net loss per share. For years in which the Company reports a net loss, diluted net loss per share is the same as basic net loss per share because their impact would be anti-dilutive to the calculation of net loss per share. For the three months ended March 31, 2025, the Company reports a combined basic net loss and diluted loss per share of common stock. Diluted net loss per share of common stock is the same as basic net loss per share of common stock for the three months ended March 31, 2026.
