EXPLANATORY NOTE

Reverse Stock Split

On April 14, 2026, we held a Special Meeting of Stockholders (the “Special Meeting”). At the Special Meeting, our stockholders voted to authorize our Board of Directors (the “Board”), in its discretion, to amend our certificate of incorporation, as amended and restated, to effect a reverse stock split of all of the outstanding shares of the Common Stock, at a ratio in the range of 1-for-10 to 1-for-30, with such ratio to be determined by the Board. Following the Special Meeting, the Board approved a reverse stock split of our issued and outstanding Common Stock, at a ratio of 1-for-10, which became effective April 27, 2026. All share information in this Quarterly Report on Form 10-Q has been restated for all years and periods presented for the impact of the 1-for-10 reverse stock split.

1. Description of Business and Basis of Financial Statements

Description of Business

Immunic, Inc. ("Immunic" or the "Company") is a late-stage biotechnology company pioneering the development of novel oral therapies for neurologic diseases. The Company is headquartered in New York City with its research and development operations in Gräfelfing near Munich, Germany. The Company had approximately 95 employees as of April 30, 2026.

The Company is pursuing clinical development of orally administered, small molecule programs, each of which has unique features intended to directly address the unmet needs of patients with serious chronic inflammatory and autoimmune diseases. These include the vidofludimus calcium (IMU-838) program, which is in Phase 3 clinical development for patients with relapsing multiple sclerosis (“RMS”), and which has shown therapeutic activity in Phase 2 clinical trials in patients suffering from relapsing-remitting multiple sclerosis ("RRMS"), progressive multiple sclerosis (”PMS”) and other diseases; the IMU-856 program, which is targeted to regenerate bowel epithelium and restore intestinal barrier function, which could potentially be applicable in numerous gastrointestinal diseases, such as celiac disease, inflammatory bowel disease (“IBD”), and Graft-versus-Host-Disease ("GvHD"); and the IMU-381 program, which comprises next-generation molecules in preclinical testing for neurologic, gastrointestinal and other autoimmune diseases leveraging Immunic's nuclear receptor-related 1 (“Nurr1”) platform.

The Company’s business, operating results, financial condition and growth prospects are subject to significant risks and uncertainties, including the failure of its clinical trials to meet their endpoints, failure to obtain regulatory approval and needing substantial additional funding to continue and potentially complete the development and commercialization of the Company's three development programs.

Liquidity and Financial Condition

Immunic has no products approved for commercial sale and has not generated any revenue from product sales. It has never been profitable and has incurred operating losses in each year since inception in 2016. The Company has an accumulated deficit of approximately $641.2 million as of March 31, 2026 and $608.6 million as of December 31, 2025. Substantially all of Immunic's operating losses resulted from expenses incurred in connection with its research and development programs and from general and administrative costs associated with its operations.

Immunic expects to incur significant expenses and increasing operating losses for the foreseeable future as it initiates and continues the development of its product candidates and adds personnel necessary to advance its pipeline of product candidates. Immunic expects that its operating losses will fluctuate significantly from quarter-to-quarter and year-to-year due to timing of development programs.

From inception through March 31, 2026, the Company raised net cash of approximately $684.9 million from private and public offerings of preferred stock, common stock, pre-funded warrants and tranche rights. As of March 31, 2026, we had cash and cash equivalents of approximately $186.6 million. With these funds we expect to be able to fund our operations beyond twelve months from the date of the issuance of the accompanying consolidated financial statements.

Basis of Presentation and Consolidation

The accompanying condensed consolidated financial statements have been prepared in conformity with United States generally accepted accounting principles ("U.S. GAAP") and include the accounts of Immunic and its wholly-owned subsidiaries, Immunic AG, Immunic Australia Pty Ltd. and Gliomic Therapeutics Inc. All intercompany accounts and transactions have been eliminated in consolidation. Immunic manages its operations as a single reportable segment for the purposes of assessing performance and making operating decisions.

Unaudited Interim Financial Information

Immunic has prepared the accompanying interim unaudited condensed consolidated financial statements in accordance with US GAAP, for interim financial information and with the instructions to Form 10-Q and Regulation S-X of the SEC.

Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. These interim unaudited condensed consolidated financial statements reflect all adjustments consisting of normal recurring accruals which, in the opinion of management, are necessary to present fairly Immunic’s consolidated financial position, consolidated results of operations, consolidated statement of stockholders’ equity (deficit) and consolidated cash flows for the periods and as of the dates presented. The Company’s fiscal year ends on December 31. The condensed consolidated balance sheet as of December 31, 2025 was derived from audited consolidated financial statements but does not include all disclosures required by U.S. GAAP. These condensed consolidated financial statements should be read in conjunction with the annual consolidated financial statements and the notes thereto included on the Company's Annual Report on Form 10-K filed on February 26, 2026. The nature of Immunic’s business is such that the results of any interim period may not be indicative of the results to be expected for the entire year or for corresponding interim periods in any subsequent year.

2. Summary of Significant Accounting Policies

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires the Company to make certain estimates and assumptions that affect the reported amounts of assets, liabilities, expenses and the disclosure of contingent assets and liabilities in the Company’s consolidated financial statements. Management believes its estimates to be reasonable under the circumstances. Actual results could differ materially from those estimates and assumptions.

Foreign Currency Translation and Presentation

The Company’s reporting currency is United States (“U.S.”) dollars. Immunic AG is located in Germany with the Euro being its functional currency. Immunic Australia Pty Ltd.’s functional currency is the Australian dollar. All amounts in the financial statements where the functional currency is not the U.S. dollar are translated into U.S. dollar equivalents at exchange rates as follows:

• assets and liabilities at reporting period-end rates;

• income statement accounts at average exchange rates for the reporting period; and

• components of equity at historical rates.

Gains and losses from translation of the financial statements into U.S. dollars are recorded in stockholders’ equity (deficit) as a component of accumulated other comprehensive income (loss). Realized and unrealized gains and losses resulting from foreign currency transactions denominated in currencies other than the functional currency are reflected as general and administrative expenses in the Consolidated Statements of Operations. Foreign currency transaction gains and losses related to long-term intercompany loans that are payable in the foreseeable future are recorded in Other Income (Expense). The Consolidated Statements of Cash Flows were prepared by using the average exchange rate in effect during the reporting period which reasonably approximates the timing of the cash flows.

Cash and Cash Equivalents

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

Cash and cash equivalents consist of cash on hand and deposits in banks located in the U.S. of approximately $137.9 million, Germany of approximately $48.6 million and Australia of approximately $0.1 million as of March 31, 2026. The Company maintains cash and cash equivalent balances denominated in Euro and U.S. dollars with major financial institutions in the U.S. and Germany in excess of the deposit limits insured by the government. Management periodically reviews the credit standing of these financial institutions. The Company currently deposits its cash and cash equivalents with two large financial institutions. Cash and cash equivalents in the U.S. are held at JP Morgan and are primarily held in a U.S. Government money market fund account earning interest at a rate of 3.54% during the period ended March 31, 2026. Cash and cash equivalents in Germany are earning interest at a rate of 1.6% to 2.2% during the period ended March 31, 2026.

Fair Value Measurement

Fair value is defined as the price that would be received to sell an asset or be paid to transfer a liability in an orderly transaction between market participants on the measurement date. Accounting guidance establishes a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair value:

Level 1—Quoted prices in active markets for identical assets or liabilities. Level 1 assets consisted of money market funds for the periods presented. The Company had no Level 1 liabilities for the periods presented.

Level 2—Inputs other than observable quoted prices for the asset or liability, either directly or indirectly; these include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active. The Company had no Level 2 assets or liabilities for the periods presented.

Level 3—Unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of assets or liabilities. The Company had no Level 3 assets for the periods presented. The Company has Stock Appreciation Rights liability starting the third quarter of 2025 through the first quarter of 2026 and stock option grants subject to shares available (see Note 7 "Stock Appreciation Rights Plan" and "Stock Options Granted Subject to Shares Available").

The carrying value of cash and cash equivalents, other current assets and prepaid expenses, accounts payable, accrued expenses, and other current liabilities approximates fair value due to the short period of time to maturity.

Property and Equipment

Property and equipment is stated at cost. Depreciation is computed using the straight-line method based on the estimated service lives of the assets, which range from three to thirteen years. Depreciation expense was $33,000 and $43,000 for the three months ended March 31, 2026 and 2025, respectively.

Impairment of Long-Lived Assets

The Company records impairment losses on long-lived assets used in operations when indicators of impairment are present and the undiscounted cash flows estimated to be generated by those assets are less than the assets’ carrying amount. Impaired assets are then recorded at their estimated fair value. There were no impairment losses during the three months ended March 31, 2026 and 2025.

Research and Development Expenses

These costs primarily include external development expenses and internal personnel expenses for its development programs, vidofludimus calcium, IMU-856 and IMU-381. Immunic has spent the majority of its research and development resources on vidofludimus calcium, the Company's lead development program, for clinical trials in MS.

Research and development expenses consist of expenses incurred in research and development activities, which include clinical trials, contract research services, certain milestone payments, salaries and related employee benefits including stock-based compensation, allocated facility costs and other outsourced services. Research and development expenses are charged to operations as incurred.

The Company enters into agreements with contract research organizations (“CROs”) to provide clinical trial services for individual studies and projects by executing individual work orders governed by a Master Service Arrangement (“MSA”). The MSAs and associated work orders provide for regular recurrent payments and payments upon the completion of certain milestones. The Company regularly assesses the timing of payments against actual costs incurred to ensure a proper accrual of related expenses in the appropriate accounting period.

Collaboration Arrangements

Certain collaboration and license agreements may include payments to or from the Company of one or more of the following: non-refundable or partially refundable upfront or license fees; development, regulatory and commercial milestone payments; payment for manufacturing supply services; partial or complete reimbursement of research and development costs;

and royalties on net sales of licensed products. The Company assesses whether such contracts are within the scope of Financial Accounting Standards Board (FASB) Accounting Standards Update (“ASU”) 2014-09 “Revenue from Contracts with Customers” and ASU No. 2018-18, “Collaborative Arrangements” ("ASU 2018-18"). ASU 2018-18, clarifies that certain elements of collaborative arrangements could qualify as transactions with customers in the scope of ASC 606.

Daiichi Sankyo Agreement

In October 2018, the Company entered into an option and license agreement (the "Daiichi Sankyo Agreement") with Daiichi Sankyo Co., Ltd. ("Daiichi Sankyo") which granted the Company the right to license a group of compounds, designated by the Company as IMU-856, as a potential new oral treatment option for gastrointestinal diseases such as celiac disease, inflammatory bowel disease, irritable bowel syndrome with diarrhea and other barrier function associated diseases. During the option period, the Company performed agreed upon research and development activities for which it was reimbursed by Daiichi Sankyo up to a maximum agreed-upon limit. Such reimbursement was recorded as other income. There are no additional research and development reimbursements expected under this agreement.

On January 5, 2020, the Company exercised its option to obtain the exclusive worldwide right to commercialization of IMU-856. Among other things, the option exercise grants Immunic AG the rights to Daiichi Sankyo’s patent application related to IMU-856, for which the Company received a notice of allowance from the U.S. Patent & Trademark Office in August 2022. In connection with the option exercise, the Company paid a one-time upfront licensing fee to Daiichi Sankyo. Under the Daiichi Sankyo Agreement, Daiichi Sankyo is also eligible to receive future development, regulatory and sales milestone payments, as well as royalties related to IMU-856.

Ludwig-Maximilians-University Agreements

Effective June 30, 2025 and November 11, 2025, Immunic AG entered into licensing agreements with the Ludwig-Maximilians-University, Munich, Germany, for an exclusive license to develop, manufacture and commercialize products derived for a series of new molecules for treating neuroinflammatory diseases. Under the agreement, the Ludwig-Maximilians-University is entitled to receive future development, regulatory and sales milestone payments related to these molecules, none of which have been earned as of March 31, 2026.

Government Assistance

Government assistance relating to research and development performed by Immunic Australia is recorded as a component of Other (Income) expense. This government assistance is recognized at a rate of 43.5% of the qualified research and development expenditures which are incurred. We also receive government assistance from the German Government for reimbursement of research and development expenses up to 4.2 million Euros per year. Based on the uncertainty of government approval, the Company does not record government assistance until approval is obtained. We recognized $0 and $1.1 million of other income related to research activities performed during the three months ended March 31, 2026 and 2025, respectively.

General and Administrative Expenses

General and administrative expenses consist primarily of salaries and related costs for personnel in executive, finance, business development and other support functions. Other general and administrative expenses include, but are not limited to, stock-based compensation, insurance costs, professional fees for legal, accounting and tax services, consulting, related facility costs and travel.

Stock-Based Compensation

The Company measures the cost of employee and non-employee services received in exchange for equity awards based on the grant-date fair value of the award recognized generally as an expense (i) on a straight-line basis over the requisite service period for those awards whose vesting is based upon a service condition, and (ii) on an accelerated method for awards whose vesting is based upon a performance condition, but only to the extent it is probable that the performance condition will be met. Stock-based compensation is (i) estimated at the date of grant based on the award’s fair value for equity classified awards and (ii) based on the final measurement date for liability classified awards. Forfeitures are recorded in the period in which they occur.

The Company estimates the fair value of stock options using the Black-Scholes-Merton option-pricing model ("BSM"), which requires the use of estimates and subjective assumptions, including the risk-free interest rate, the expected dividend yield of the Company’s common stock, the expected volatility of the price of the Company’s common stock, and the expected term of the option. These estimates involve inherent uncertainties and the application of management’s judgment. If factors change and different assumptions are used, the Company’s stock-based compensation expense could be materially different in the future.

Stock Appreciation Rights ("SARs")

The Company may issue SARs to its employees in exchange for services. The Company estimates the fair value of SARs using a Monte Carlo simulation, which requires the use of estimates and subjective assumptions, including the risk-free interest rate, the probability of a corporate transaction, the expected dividend yield of the Company's common stock, the expected volatility of the price of the Company's common stock, and the expected term of the SARs. These estimates involve inherent uncertainties and the application of management's judgment. If factors change and different assumptions are used, the Company's stock-based compensation expense could be materially different in the future.

If SARs meet the requirements to be classified as a liability, the Company measures the SARs at each reporting date at their fair value and recognizes expense based on the latest fair value for the percentage the requisite service period that has been provided for each vesting condition contained within the SAR award, which may relate to service, market and performance conditions depending on the terms of the award.

Issuance of Common Stock

The Company issues new shares of stock upon the exercise of stock options, SARs and warrants.

Leases

The Company leases office space and office equipment. The underlying lease agreements have lease terms of less than 12 months and up to 60 months. Leases with terms of 12 months or less at inception are not included in the operating lease right of use asset and operating lease liability.

The Company has three existing leases for office and laboratory space. At inception of a lease agreement, the Company determines whether an agreement represents a lease and at commencement each lease agreement is assessed as to classification as an operating or financing lease. The Company's leases have been classified as operating leases and an operating lease right-of-use asset and an operating lease liability have been recorded on the Company’s consolidated balance sheet for leases that have terms greater than 12 months. A right-of-use lease asset represents the Company’s right to use the underlying asset for the lease term and the lease obligation represents its commitment to make the lease payments arising from the lease. Right-of-use lease assets and obligations are recognized at the commencement date based on the present value of remaining lease payments over the lease term. As the Company’s leases do not provide an implicit rate, the Company has used an estimated incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. The right-of-use lease asset includes any lease payments made prior to commencement and excludes any lease incentives. The lease term used in estimating future lease payments may include options to extend when it is reasonably certain that the Company will exercise that option. Operating lease expense is recognized on a straight-line basis over the lease term, subject to any changes in the lease or changes in expectations regarding the lease term. Variable lease costs such as common area costs and property taxes are expensed as incurred.

Comprehensive Income (Loss)

Comprehensive income (loss) is defined as the change in equity during a period from transactions and other events and circumstances from non-owner sources. Accumulated other comprehensive income (loss) has been reflected as a separate component of stockholders’ equity (deficit) in the accompanying Consolidated Balance Sheets and consists of foreign currency translation adjustments.

Income Taxes

The Company is subject to corporate income tax laws and regulations in the U.S., Germany and Australia. Tax regulations within each jurisdiction are subject to the interpretation of the related tax laws and regulations and require significant judgment in their application.

The Company utilizes the asset and liability method of accounting for income taxes which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the consolidated financial statements. Deferred income tax assets and liabilities are determined based on the differences between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of changes in tax rates on deferred tax assets and liabilities is recognized in operations in the period that includes the enactment date. Deferred taxes are reduced by a valuation allowance when, in the opinion of management, it is more likely than not some portion or the entire deferred tax asset will not be realized. As of March 31, 2026 and December 31, 2025, the Company maintained a full valuation allowance against the balance of deferred tax assets.

It is the Company’s policy to provide for uncertain tax positions and the related interest and penalties based upon management’s assessment of whether a tax benefit is more likely than not to be sustained upon examination by tax authorities. The Company recognizes interest and penalties accrued on any unrecognized tax benefits as a component of income tax expense. The Company is subject to U.S. federal, New York, California, Massachusetts, North Carolina, Texas, German and Australian income taxes. The Company is subject to U.S. federal or state income tax examination by tax authorities for tax returns filed for the years 2003 and forward due to the carryforward of NOLs. Tax years 2019 through 2025 are subject to audit by German and Australian tax authorities. The Company is currently under examination by German tax authorities for its Immunic AG and Immunic GmbH subsidiaries for the years ended December 31, 2021-2023.

Warrants and Tranche Rights

The Company accounts for issued financial instruments either as a liability or equity in accordance with ASC 480-10, Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity (“ASC 480-10”) or ASC 815-40, Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Company’s Own Stock (“ASC 815-40”). If financial instruments do not meet liability classification under ASC 480-10, the Company considers the requirements of ASC 815-40 to determine whether the financial instruments should be classified as a liability or as equity. Liability-classified financial instruments are measured at fair value on the issuance date and at the end of each reporting period. Any change in the fair value of the financial instruments after the issuance date is recorded in the Consolidated Statements of Operations as a gain or loss. If financial instruments do not require liability classification under ASC 815-40, the instrument is classified in permanent equity. Equity-classified financial instruments are accounted for based on allocated proceeds on the issuance date with no subsequent measurement after the issuance date.

Net Loss Per Share

Basic net loss per share attributable to common stockholders is calculated by dividing the net loss by the weighted-average number of common shares outstanding for the period, without consideration for common stock equivalents. Diluted net loss per share attributable to common stockholders is computed by dividing the net loss by the weighted-average number of common shares and, if dilutive, common stock equivalents outstanding for the period determined using the treasury-stock method. For all periods presented, there is no difference in the number of shares used to calculate basic and diluted shares outstanding due to the Company’s net loss position. The weighted average shares outstanding calculation for basic and diluted earnings per share for the three months ended March 31, 2026 includes 858,015 pre-funded warrants from the January 2024 Financing and 5,119,867 pre-funded warrants from the May 2025 Offering and 22,907,600 pre-funded warrants from the February 2026 Offering that remain unexercised as of March 31, 2026. The weighted average shares outstanding calculation for basic and diluted earnings per share for the three months ended March 31, 2025 includes 1,119,356 pre-funded warrants that were unexercised as of March 31, 2025.

Potentially dilutive securities, not included in the calculation of diluted net loss per share attributable to common stockholders because to do so would be anti-dilutive, are as follows:


	As of March 31,
	2026	2025
Options to purchase common stock	2,582,306	1,620,859
Placement agent warrants	28,333	—



Series B Warrants	3,357,967	—
	5,968,606	1,620,859

Recently Issued Accounting Standards

In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income (Topic 220): Expense Disaggregation Disclosures to improve the disclosures about a public entity’s expenses and provide more detailed information about the types of expenses in commonly presented expense captions such as inventory purchases, employee compensation, depreciation and intangible asset amortization. The disclosure requirements may be applied prospectively for the current year or retrospectively for all prior periods presented in the financial statements during the year of adoption. The effective date for the standard is for fiscal years beginning after December 15, 2026 and interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the effects adoption of this guidance will have on the consolidated financial statements.

4. Leases

Operating Leases

The Company leases certain office space under non-cancelable operating leases. The New York City office lease terminates on July 31, 2026, the lease for the research laboratory in Planegg, Germany terminates on November 30, 2028. The lease term has expired for the Gräfelfing, Germany office, however, the Company is currently operating on a one-year monthly rolling lease and the Company needs to provide one-years notice to terminate the lease. Renewal options were not included in calculating the right of use asset and liabilities for this facility. These agreements include both lease (e.g., fixed rent) and non-lease components (e.g., common-area and other maintenance costs). The non-lease components are deemed to be executory costs and are therefore excluded from the minimum lease payments used to determine the present value of the operating lease obligation and related right-of-use asset. The New York City lease was extended on November 8, 2024 for an additional 12 months resulting in the new lease termination date of July 31, 2026. The New York City lease has a renewal option, but this was not included in calculating the right of use asset and liabilities. In February 2023, the Company leased space in Germany for a research laboratory. The leases do not have concessions, leasehold improvement incentives or other build-out clauses. Further, the leases do not contain contingent rent provisions.

The leases do not provide an implicit rate and, due to the lack of a commercially salable product, the Company is generally considered unable to obtain commercial credit. Therefore, the Company estimated its incremental interest rate to be 6% for the original leases and 8% for the New York City extension and German laboratory, considering the quoted rates for the lowest investment-grade debt. Immunic used its estimated incremental borrowing rate and other information available at the lease commencement date in determining the present value of the lease payments.

Immunic’s operating lease costs and variable lease costs were $335,000 and $279,000 for the three months ended March 31, 2026 and 2025, respectively. Variable lease costs consist primarily of common area maintenance costs, insurance and taxes which are paid based upon actual costs incurred by the lessor.

Maturities of the operating lease obligation are as follows as of March 31, 2026:


2026	$	272,000
2027		88,000
2028		85,000
2029		—

There were no transfers between Level 1, Level 2 or Level 3 assets during the periods presented.

For the Company’s money market funds which are included as a component of cash and cash equivalents on the consolidated balance sheet, realized gains and losses are included in interest income on the consolidated statements of operations.

Our money market fund account is held in our bank in the U.S. and was earning interest at a rate of 3.54% in a U.S. Government money market fund.

The Company has cash balances in banks in excess of the maximum amount insured by the FDIC and other international agencies as of March 31, 2026. The Company has not historically experienced any credit losses with balances in excess of FDIC limits.

The Company recorded a SARs liability of $2.7 million and $0.8 million and as of March 31, 2026 and December 31, 2025, respectively, as a result of the grant of up to 3.5 million SARs in July 2025 (see note 7). The fair value of the SARs liability was classified as Level 3 under the fair value hierarchy. A rollforward of the fair value of the SARs liability is as follow (in thousands)


Fair value of SARs liability at December 31, 2025	$	809
Change in fair value of SARs liability	1,901
Fair value of SARs liability at March 31, 2026	$	2,710

The Company utilized a Monte Carlo simulation model in conjunction with a Probability-Weighted Expected Return Model (“PWERM”) to estimate the fair value of the SARs liabilities. This valuation model incorporates various assumptions, including stock price volatility, risk-free interest rate, corporate transaction probability and the expected term of the underlying equity instruments and SARs.

The following table summarizes the key assumptions used in estimating the fair value of the SARs on March 31, 2026 and December 31, 2025:


	March 31, 2026	December 31, 2025
Expected term (years)	1.08-2.96	1.00-2.40
Risk-free interest rate	3.75%-4.21%	3.64%-4.11%
Stock price volatility	80%-115%	65%-115%

Probability (1)	50%-50%	50%-50%
Dividend rate	—%	—%

(1) Scenario probability was based on timing expectations of the Company that a corporate transaction occurring was estimated at 50%; and a corporate transaction not occurring at 50%.

The Company recorded a liability for stock options granted subject to shares available of $1.1 million and $0 as of March 31, 2026 and December 31, 2025, respectively, as a result of the grant of 177,590 stock options on March 27, 2026 (see note 7). The fair value of the stock options granted subject to shareholder approval liability was classified as Level 3 under the fair value hierarchy. A rollforward of the fair value of the Stock Options issued subject to shares available liability is as follows (in thousands):


Fair value of stock options granted subject to shares available liability at December 31, 2025	$	—
Stock options granted subject to shares available liability	1,123
Fair value of stock options granted subject to shares available liability at March 31, 2026	$	1,123

The Company utilized a Black-Scholes valuation model to estimate the fair value of the stock options granted subject to shares available liability. This valuation model incorporates various assumptions, including stock price volatility, risk-free interest rate, and the expected term of the liability. The grant date assumptions are as follows: the risk free interest rate associated with these grants ranges from 4.06%-4.13%, volatility ranges from 110%-113%, there is no dividend and the expected term ranges from 5-5.8 years.

The carrying amounts of other current assets and prepaid expenses, accounts payable, accrued expenses, and other current liabilities approximate their fair values due to their short-term nature. The fair value and book value of the money market funds presented in the table above are the same.

6. Common Stock

Shelf Registration Statements

In December 2020, the Company filed a Prospectus Supplement to the shelf registration statement on Form S-3 filed on November 13, 2020 and declared effective on November 24, 2020 (the "2020 Shelf Registration Statement") for the offering, issuance and sale of up to a maximum aggregate offering price of $50.0 million of common stock that may be issued and sold under an at-the-market sales agreement with SVB Leerink LLC (now Leerink Partners LLC) as agent ("December 2020 ATM"). The Company used the net proceeds from the December 2020 ATM to fund the ongoing clinical development of our product candidates and for other general corporate purposes, including funding existing and potential new clinical programs and product candidates. The December 2020 ATM terminated in May 2024.

In May 2022, the Company filed a Prospectus Supplement to the 2020 Shelf Registration Statement for the offering, issuance and sale of up to a maximum aggregate offering price of $80.0 million of common stock to be issued and sold under another at-the-market sales agreement ("May 2022 ATM") with Leerink Partners LLC (formerly SVB Leerink LLC) as agent. The 2020 Shelf Registration Statement expired in November 2023.

In November 2023, the Company filed a shelf registration statement on Form S-3 (the "2023 Shelf Registration Statement"). The 2023 Shelf Registration Statement permits the offering, issuance and sale of up to $250.0 million of common stock, preferred stock, warrants, debt securities, and/or units in one or more offerings and in any combination of the foregoing. This registration statement was declared effective on May 31, 2024. Unsold securities from the expired 2020 Shelf Registration Statement can continue to be sold under the 2023 Shelf Registration Statement. As a result of the April 2025 Offering and May 2025 Offering, the total amount available under the 2023 Shelf Registration Statement was reduced by $70.1 million to $262.2 million as of March 31, 2026. The Company can also use the unused amount of the available ATM as additional shelf availability.

In May 2024, we filed a Prospectus Supplement to the 2023 Shelf Registration Statement for the offering, issuance and sale of up to a maximum aggregate offering price of $80.0 million of common stock that may be issued and sold under an at-the-market sales agreement with Leerink Partners LLC as agent ("May 2024 ATM"), which rolls over the $80.0 million of unsold common stock from the May 2022 ATM. We intend to use the net proceeds from the May 2024 ATM to continue to fund the ongoing clinical development of our product candidates and for other general corporate purposes, including funding existing and potential new clinical programs and product candidates. The May 2024 ATM will terminate upon the earlier of (i) the issuance and sale of all of the shares through Leerink Partners LLC on the terms and subject to the conditions set forth in the May 2024 ATM or (ii) termination of the May 2024 ATM as otherwise permitted thereby. The May 2024 ATM may be terminated at any time by either party upon ten days’ prior notice, or by Leerink Partners LLC at any time in certain circumstances, including the occurrence of a material adverse effect on us. As of March 31, 2026, $80.0 million in capacity remains under the May 2024 ATM.

The Company has agreed to pay Leerink Partners LLC a commission equal to 3.0% of the gross proceeds from the sales of common stock pursuant to the May 2024 ATM and has agreed to provide Leerink Partners LLC with customary indemnification and contribution rights.

The Company did not have any ATM activity during the three months ended March 31, 2026 and 2025, respectively.

February 2026 Private Placement

Securities Purchase Agreement

On February 12, 2026, we entered into a securities purchase agreement (the “February Securities Purchase Agreement”) with certain accredited investors (the “February Investors”), pursuant to which we agreed to issue and sell, in a private placement (the “February 2026 Offering”), pre-funded warrants (the “February 2026 Pre-Funded Warrants”, and the shares of Common Stock issuable upon exercise of the February 2026 Pre-Funded Warrants, the “February 2026 Pre-Funded Warrant Shares”) to purchase up to one share of Common Stock at a price of $0.001, with each February 2026 Pre-Funded Warrant accompanied by a warrant to purchase (i) a share of Common Stock or (ii) a pre-funded warrant to purchase a share of Common Stock (collectively, the “February 2026 Common Warrants” and together with the February 2026 Pre-Funded Warrants, the “February 2026 Warrants”, and the shares of Common Stock issuable upon exercise of the February 2026 Common Warrants, the “February 2026 Common Warrant Shares”, and together with the February 2026 Pre-Funded Warrant Shares, the “February 2026 Warrant Shares”).

The purchase price for each February 2026 Pre-Funded Warrant and accompanying February 2026 Common Warrant was $8.73. Each February 2026 Pre-Funded Warrant is immediately exercisable at a price of $0.001 per share. Each February 2026 Common Warrant is exercisable at a price $8.73 per share (subject to adjustment as set forth therein) following the completion of the Reverse Stock Split until the earlier of (i) 30 trading days following the date of our initial public announcement of topline data from its Phase 3 ENSURE trials (for the avoidance of doubt, the later date of the initial public announcement of topline data from ENSURE-1 or ENSURE-2, if announced separately) (the “Topline Data Announcement”), (ii) immediately upon the exercise of the February 2026 Pre-Funded Warrants if such exercise of February 2026 Pre-Funded Warrants is prior to the Topline Data Announcement, provided that if the February 2026 Pre-Funded Warrant is not exercised in full, the February 2026 Common Warrant expires proportionally only to the extent the Pre-Funded Warrant is exercised, and (iii) February 17, 2031.

The Offering closed on February 17, 2026 (the “February 2026 Closing Date”).

The Company issued 22,907,600 February 2026 Pre-Funded Warrant Shares. The aggregate gross proceeds to the Company from the issuance and sale of the February 2026 Warrants was $200 million, before deducting fees paid to the placement agents and financial advisors of the Company of $12.7 million, for net proceeds of $187.3 million.

As compensation in connection with the February 2026 Offering, we agreed to pay the placement agents a fee equal to 6% of the aggregate gross proceeds received by us (i) upon the issuance of the February 2026 Warrants at closing and (ii) upon the cash exercise of the February 2026 Common Warrants.

The Offering

The securities issued in the February 2026 Offering have not been registered under the Securities Act, and until so registered the securities may not be offered or sold absent registration or availability of an applicable exemption from registration. There is no established public trading market for the February 2026 Warrants, and we do not intend to list such securities on any national securities exchange or nationally recognized trading system. On April 2, 2026, we filed a registration statement on Form S-3 (File No. 333-294855) to register the Registrable Securities for resale by the February Investors, which registration statement was amended on April 30, 2026, and declared effective by the SEC on May 4, 2026.

Royalty Exchange Agreement

As previously disclosed, on June 3, 2025, the Company issued Series B Common Stock Warrants to purchase up to an aggregate of 8,666,667 shares of Common Stock (or prefunded warrants to purchase shares of Common Stock) in an underwritten public offering (the “Series B Warrants”). On February 12, 2026, in conjunction with our February 2026 Private Placement, the Company entered into a purchase and sale agreement (the “Royalty Exchange Agreement”) with certain Series B Warrant holders who had purchased a predetermined number of Series B Warrants (each a “Participating Series B Holder”) and BVF Partners, L.P. (“BVF”), acting as royalty interest agent (the “Warrant Exchange”). The Participating Series B Holders were also required to participate in the February private placement in order to participate in the Warrant Exchange.

by the Company to the Participating Series B Holders following the First Commercial Sale (as defined in the Royalty Exchange Agreement). The Company determined that the Royalty Interests do not meet the criteria for recognition as a liability. The Company will recognize amounts payable under the Royalty Interests when they become probable and estimable.

On the Closing Date, Series B Warrants to purchase up to an aggregate of 5,108,700 shares of Common Stock were surrendered by Participating Series B Holders and cancelled in exchange for the Royalty Interests. As this exchange occurred as part of an equity financing with the participating investor on the Closing Date, the effect of the exchange was reflected as an equity issuance cost net within additional paid in capital.

Special Meeting and Reverse Stock Split

On April 14, 2026, we held a Special Meeting of Stockholders (the “Special Meeting”). At the Special Meeting, our stockholders voted to authorize our Board of Directors, in its discretion, to amend our certificate of incorporation, as amended and restated, to effect a reverse stock split of all of the outstanding shares of the Common Stock, at a ratio in the range of 1-for-10 to 1-for-30, with such ratio to be determined by the Board. Following the Special Meeting, the Board approved a reverse stock split of our issued and outstanding Common Stock, at a ratio of 1-for-10 shares, which became effective April 27, 2026 (the “Reverse Stock Split”).

April 2025 Offering

On April 9, 2025, we entered into a securities purchase agreement with certain institutional and accredited investors relating to the issuance and sale of an aggregate of 566,667 shares of our Common Stock (the “April 2025 Shares”). The purchase price per share was $9.00 for aggregate gross proceeds of approximately $5.1 million. The offer and sale of the shares is referred to herein as the “April 2025 Offering.” The April 2025 Offering closed on April 10, 2025.

In addition, on April 9, 2025, the Company entered into a placement agency agreement with Titan Partners Group LLC, a division of American Capital Partners, LLC (the “Placement Agent”), relating to the April 2025 Offering. Pursuant to the Placement Agency Agreement, the Company agreed to pay the Placement Agent a cash fee of 6.0% of the gross proceeds from the April 2025 Offering raised from investors and to reimburse the Placement Agent for certain costs incurred in connection therewith. Additionally, upon the closing of the April 2025 Offering, the Company agreed to issue to the Placement Agent, or its designees, warrants to purchase up to an aggregate of 28,333 shares of common stock, representing 5.0% of the shares sold in the April 2025 Offering (the “Placement Agent Warrants”). The Placement Agent Warrants are exercisable, in whole or in part, for five years from the anniversary of the Placement Agency Agreement, at an initial exercise price per share of common stock of $11.25, which is equal to 125% of the price per share to investors in the April 2025 Offering. The Placement Agent Warrants and the shares of common stock underlying the Placement Agent Warrants were offered pursuant to the exemptions from registration provided in Section 4(a)(2) under the Securities Act and Regulation D promulgated thereunder.

The net proceeds to the Company from the April 2025 Offering, after deducting commissions and the Company’s offering expenses, was approximately $4.7 million.

The April 2025 shares were registered under the Securities Act, on the Company’s Registration Statement on Form S-3 (Registration No. 333-275717), previously filed with the SEC, and declared effective on May 31, 2024.

May 2025 Equity Offering

On May 28, 2025, we entered into an underwriting agreement (the “May 2025 Underwriting Agreement”) with Leerink Partners LLC, for the issuance and sale of (i) pre-funded warrants to purchase an aggregate of 8,666,667 shares of Common stock (the “May 2025 Pre-Funded Warrants”), (ii) accompanying series A warrants to purchase an aggregate of 8,666,667 shares of Common Stock (or Pre-Funded Warrants) (the “Series A Warrants”), and (iii) accompanying series B warrants to purchase an aggregate of 8,666,667 shares of Common Stock (or Pre-Funded Warrants) (the “Series B Warrants”) (the “May 2025 Offering”). The price per May 2025 Pre-Funded Warrant and accompanying Series A Warrant and Series B Warrant was $7.499.

Each Pre-Funded Warrant is immediately exercisable for one share of Common Stock at an exercise price of $0.001 per share and will expire when exercised in full. The Series A Warrants were exercisable for one share of Common Stock at an exercise price of $7.50 per share. All of the Series A Warrants expired as of March 31, 2026. Each Series B Warrant is exercisable for one share of Common Stock at an exercise price of $7.50 per share and will expire five years from the date of issuance. The holder of the Pre-Funded Warrants and Series B Warrants may also satisfy its obligation to pay the exercise price through a “cashless exercise,” in which the holder receives the net value of such warrant in shares of Common Stock determined according to the formula set forth in the applicable warrant.

The aggregate proceeds from the May 2025 Offering were approximately $65 million before deducting underwriting discounts and commissions and offering expenses payable by the Company in connection with the May 2025 Offering. On February 17, 2026, as part of the February 2026 Private Placement, 5,108,700 warrants were exchanged for the right to share a 5% royalty. On March 10, 2026, 200,000 of the Series B warrants were exercised for $1.4 million in net cash proceeds, resulting in 3,357,967 Series B Warrants outstanding as of March 31, 2026. The Company may receive up to an aggregate of approximately $25.2 million of additional gross proceeds if the remaining Series B Warrants are exercised in full for cash. Pursuant to the Placement Agency Agreement, the Company agreed to pay the Placement Agent a cash fee of 6.0% of the gross proceeds from the May 2025 Offering raised from investors and to reimburse the Placement Agent for certain costs incurred in connection therewith.

Common Stock

On March 4, 2024, the stockholders of the Company voted to increase the authorized shares of the Company from 130,000,000 shares of common stock to 500,000,000 shares of common stock, par value of $0.0001 per share. The voting, dividend and liquidation rights of the holders of the Company’s common stock are subject to and qualified by the rights, powers and preferences of any holders of preferred stock.

Each share of common stock entitles the holder to one vote on all matters submitted to a vote of the Company’s stockholders. Common stockholders are entitled to receive dividends, as may be declared by the Board of Directors, if any. Through March 31, 2026, no cash dividends had been declared or paid.

Regained Compliance with Nasdaq Minimum Bid Price Requirement

On April 1, 2026, the Company announced that it received written notice from the Listing Qualifications Department of The Nasdaq Stock Market LLC ("Nasdaq") on March 27, 2026, informing the Company that it has regained compliance with the minimum bid price requirement under Nasdaq Listing Rule 5550(a)(2) for continued listing on The Nasdaq Capital Market.

According to the Notice, Immunic has regained compliance with the minimum bid price requirement, because the closing bid price of the Company's common stock was at $1.00 per share or greater for at least 20 consecutive business days, satisfying the Nasdaq requirement on March 26, 2026. As a result, the matter was closed.

Pre-funded Warrants

The Company issued 1,119,356 pre-funded warrants in connection with a financing in January 2024, 261,341 of which were exercised into 261,341 shares of common stock in the quarter ended June 30, 2025 and 858,015 of the pre-funded warrants remain outstanding as of March 31, 2026.

The Company issued 8,666,667 pre-funded warrants in connection with the May 2025 Offering, 2,163,500 of which were exercised into 2,163,413 shares of common stock in the year ended December 31, 2025 and 1,383,300 of which were exercised into 1,383,220 shares of common stock in the quarter ended March 31, 2026. 5,119,867 of pre-funded warrants remain outstanding as of March 31, 2026.

The Company issued 22,907,600 pre-funded warrants in connection with the February 2026 Pre-funded Warrant Shares in the February 2026 Private Placement, which are accompanied by a warrant to purchase one share of common stock or a pre-funded warrant to purchase a share of common stock subject to exercise restrictions, all of which are still outstanding as of March 31, 2026.

Preferred Stock

The Company’s certificate of incorporation, as amended and restated, authorizes the Company to issue 20 million shares of $0.0001 par value preferred stock, with such voting powers (if any), designations, powers, preferences, and relative, participating, optional or other rights, if any, and any qualifications, limitations or restrictions thereof, as shall be set by the Board of Directors. No preferred shares were outstanding as of March 31, 2026.

7. Stock-Based Compensation Plans

2021 Employee Stock Purchase Plan

On April 25, 2021, the Company adopted the 2021 Employee Stock Purchase Plan ("ESPP"), which was approved by stockholder vote at the 2021 Annual Meeting of Stockholders held on June 10, 2021. The ESPP provides eligible employees of the Company with an opportunity to purchase common stock of the Company through accumulated payroll deductions, which are included in other current liabilities until they are used to purchase Company shares. Eligible employees participating in the bi-annual offering period can choose to have up to the lesser of 15% of their annual base earnings or the IRS annual share purchase limit of $25,000 in aggregate market value to purchase shares of the Company’s common stock. The purchase price of the stock is the lesser of (i) 85% of the closing market price on the date of purchase and (ii) the closing market price at the beginning of the bi-annual offering period. The maximum number of shares initially reserved for delivery under the plan was 20,000 shares. An increase of 100,000 shares to 120,000 shares was approved by stockholders of the Company at the Company's Special Meeting of stockholders held on March 4, 2024.

The first enrollment period under the plan commenced on August 1, 2021 and the Company has issued 58,974 shares life-to-date under the ESPP. The Company recognized $16,000 and $26,000 of stock based compensation expense related to the plan during the three months ended March 31, 2026 and 2025, respectively.

Stock Option Programs

In July 2019, the Company’s stockholders approved the 2019 Omnibus Equity Incentive Plan, (as amended, the “2019 Plan”), which was adopted by the Board of Directors (the "Board") with an effective date of June 14, 2019. The 2019 Plan allows for the grant of equity awards to employees, consultants and non-employee directors. An initial maximum of 150,000 shares of the Company’s common stock were available for grant under the 2019 Plan. The 2019 Plan included an evergreen provision that allowed for the annual addition of up to 4% of the Company’s fully-diluted outstanding stock, with a maximum allowable increase of 490,000 shares over the term of the 2019 Plan. In accordance with this provision, the shares available for grant were increased in 2020 through 2023 by a total of 440,887 shares. At the Company's Annual Stockholders meeting on June 28, 2023, stockholders voted to increase the allowable shares under the 2019 plan by 444,000 shares as well as to eliminate the evergreen provision. On March 4, 2024, the stockholders voted at the Company's Special Meeting to increase the allowable shares under the 2019 plan by 910,000 shares. On June 4, 2025, at the Company’s 2025 Annual Meeting of Stockholders, the Company’s stockholders approved a proposal to amend the terms of the 2019 Plan to, among other things, increase the allowable shares under the 2019 plan by 700,000 shares. The 2019 Plan (as amended on June 28, 2023, March 4, 2024 and June 4, 2025) is currently administered by the Board, or, at the discretion of the Board, by a committee of the Board, which determines the exercise prices, vesting schedules and other restrictions of awards under the 2019 Plan at its discretion. Options to purchase stock may not have an exercise price that is less than the fair market value of underlying shares on the date of grant, and may not have a term greater than ten years. Incentive stock options granted to employees typically vest over four years. Non-statutory options granted to employees, officers, members of the Board, advisors, and consultants of the Company typically vest over three or four years.

Shares that are expired, terminated, surrendered or canceled under the 2019 Plan without having been fully exercised will be available for future awards.

Corporate Transaction Option Acceleration Plan

On February 4, 2025, the Company established a Corporate Transaction Option Acceleration Plan, pursuant to which in the case of a merger or consolidation of the Company with or into another corporation or a sale of substantially all of the stock of the Company each option award held by an eligible employee will become fully vested upon the occurrence of a Corporate Transaction.

Measurement

The weighted-average assumptions used in the BSM option pricing model to determine the fair value of the employee and non-employee stock option grants relating to the 2019 Plan were as follows:

Risk-Free Interest Rate

The risk-free rate assumption is based on U.S. Treasury instruments with maturities similar to the expected term of the stock options.

Expected Dividend Yield

The Company has not issued any dividends and does not expect to issue dividends over the life of the options. As a result, the Company has estimated the dividend yield to be zero.

Expected Volatility

The Company estimates expected volatility based on the historical volatility of its own stock. The historical volatility data was computed using the daily closing prices during the equivalent period of the calculated expected term of the stock-based awards.

Expected Term

The expected term of options is estimated considering the vesting period at the grant date, the life of the option and the average length of time similar grants have remained outstanding in the past.

The weighted-average grant date fair value of equity classified stock options granted under the 2019 Plan during the three months ended March 31, 2026 and 2025 was $7.10 and $6.50, respectively. The following are the underlying assumptions used in the Black-Scholes option pricing model to determine the fair value of stock options granted to employees and to non-

employees under this stock plan. The expected term of the options for the three months ended March 31, 2025 includes a grant to a non-employee consultant where the term of the option is five years compared to employee grants that are ten years:


	Three Months Ended March 31,
	2026	2025
Risk-free interest rate	3.81%	4.36%
Expected dividend yield	0%	0%
Expected volatility	111.0%	95.2%
Expected term of options (years)	6.10	3.50

As of March 31, 2026, there was $10.5 million in total unrecognized compensation expense relating to the 2019 Plan, to be recognized over a weighted average period of 2.73 years.

Stock Options Granted Subject to Shares Available

On March 27, 2026, there was a total grant of 177,590 stock options that are subject to shareholder approval to increase the number of shares available for grant under the 2019 Plan. As there are currently insufficient shares available to cover the grant, these amounts are excluded from the shares reserved for future issuance table in Note 6. Of these grants, 126,850 were fully vested upon issuance. The weighted average grant date fair value of all these grants is $8.96. As of March 31, 2026, the stock-based compensation expense associated with these grants was $1.1 million and is recorded in other current liabilities on the Consolidated Balance Sheet until such time they receive shareholder approval and would then be reclassified to Additional Paid in Capital. There is $460,789 of unrecognized stock compensation associated with the unvested grants, to be recognized over a weighted average period of 2.99 years. The assumptions as of the grant date and March 31, 2026 are as follows: the risk free interest rate associated with these grants ranges from 4.06%-4.13%, volatility ranges from 110%-113%, there is no dividend and the expected term ranges from 5-5.8 years.

Stock Appreciation Rights Plan

On July 7, 2025, the Board of Directors of Immunic, Inc. authorized grants, of up to an aggregate of 3,500,000 stock appreciation rights (“SARs”) to the Company’s employees and executive officers. The SARs are settleable in cash until such time in which the Company has sufficient number of shares of common stock to support settlement of the SARs with shares. The Company intends to seek stockholder approval to increase the number of shares available under the Company's 2019 Omnibus Equity Incentive Plan. The exercise price of each SAR is $7.65, the closing price of the common stock on July 7, 2025.

The approximately 3,500,000 SARs granted consisted of five distinct tranches:

•Time Based SARs (TB SARs): There were 500,000 TB SAR's issued which will be exercisable beginning August 1, 2026. The number of TB SARs exercisable is fixed, and their exercisability is only subject to the time vesting condition. The TB SARs vest on August 1, 2026 and expire ten years from the date of grant.

•SARs tied to the exercise of Series A Warrants (SA SARs): The maximum number of SA SARs was capped at up to 1,000,000, but the number of SARs exercisable is determined based on the percentage of Series A Warrants to be exercised out of a total of 8,666,667 shares of Series A Warrants issued. As of March 31, 2026, all of the Series A warrants and SA SARs expired unexercised.

•SARs tied to the exercise of Series B Warrants (SB SARs): The maximum number of SB SARs is capped at up to 1,000,000, but the number of SARs exercisable is determined based on the percentage of Series B Warrants to be exercised out of a total of 8,666,667 shares of Series B Warrants issued. On February 17, 2026, Series B Warrants to purchase up to an aggregate of 5,108,700 shares of Common Stock were surrendered by Participating Series B Holders and cancelled. Series B Warrants to purchase up to an aggregate of 3,357,967 shares of Common Stock remain issued and outstanding. The Potential SARs that were associated with the Series B Warrants that were cancelled were also cancelled. This results in a revised potential issuance of 410,535 Series B SARs instead of 1,000,000. On March 10, 2026, 200,000 of the remaining Series B warrants were exercised for cash resulting in the issuance of 23,077 Series B SARS. The Vesting of SB SARs that were not exercised are subject to service and implied market conditions. The SB SARs vest on August 1, 2026 and expire ten years from the date of grant (see Note 6 "February 2026 Private Placement-Royalty Exchange Agreement").

•SARs tied to the issuance of Tranche Two Shares (T2 SARs): The maximum number of T2 SARs was capped at up to 500,000, but the number of SARs exercisable was determined based on the percentage of Tranche Two Shares issued out of a total of 4,662,005 shares. Vesting of T2 SARs was subject to service, implied performance and market

conditions. These SARs will not be exercised as the second tranche from the January 4, 2024 Financing was not exercised by October 31, 2025.

•SARs tied to the issuance of Tranche Three Shares (T3 SARs): The maximum number of T3 SARs was capped at up to 500,000, but the number of SARs exercisable is determined based on the percentage of Tranche Three Shares issued out of a total of 4,662,005 shares. Vesting of T3 SARs were subject to service, implied performance and market conditions. These SARs will not be exercised as the third tranche from the January 4, 2024 Financing was not exercised by October 31, 2025.

The Company evaluates the classification of the awards for equity or liability treatment based on the terms of the agreement and contemplates whether adequate authorized shares exists to settle the exercise of the SARs with shares. The SARs will be liability classified until the Company receives shareholder approval to increase the number of shares available for issuance under the Plan. If approval is received, the Company will then control the settlement of the SARS in shares and will meet all other criteria to be classified as equity. SARs are currently classified as liability awards and measured at fair value at each reporting date.

The Company’s SARs activity is as follows:


SARs grants	Shares	Weighted average exercise price	Weighted average remaining contractual term (years)	Aggregate intrinsic value
Balance at January 1, 2026	1,623,007	$7.65
SARs granted	—	$—
SARs forfeited or expired	(715,308)	$7.65
SARs exercised	—	$—
Balance at March 31, 2026	907,699	$7.65	9.23	$3,131,563
Exercisable at March 31, 2026	—	$—	—	—

The March 31, 2026 fair value of the SARs is $6.20 per share for TB SARs and $7.27 per share for SB SARs.

For the three months ended March 31, 2026, the Company recognized $1.9 million of compensation expense and corresponding liability of $2.7 million as of March 31, 2026 for the SARs. There was no expense for the three months ended March 31, 2025. As of March 31, 2026, the unrecognized compensation expense is $3.4 million which is expected to be recognized over a weighted average period of 2.2 years.

The Company utilized a Monte Carlo simulation model in conjunction with a Probability-Weighted Expected Return Model (“PWERM”) to estimate the fair value of the SARs liabilities. This valuation model incorporates various assumptions, including stock price volatility, risk-free interest rate, the probability of a corporate transaction, and the expected term of the underlying equity instruments and SARs.

The following table summarizes the key assumptions used in estimating the fair value of the SARs at March 31, 2026 and December 31, 2025:


	March 31, 2026	December 31, 2025
Expected term (years)	1.08-2.96	1.00-2.40
Risk-free interest rate	3.75%-4.21%	3.64%-4.11%
Stock price volatility	80%-115%	65%-115%

Probability (1)	50%-50%	50%-50%
Dividend rate	—%	—%

(1) Scenario probability was based on timing expectations of the Company that a corporate transaction occurring was estimated at 50%; and a corporate transaction not occurring at 50%.

Legal Proceedings

The Company is not currently a party to any litigation, nor is it aware of any pending or threatened litigation, that it believes would materially affect its business, operating results, financial condition or cash flows. However, its industry is characterized by frequent claims and litigation including securities litigation, claims regarding patent and other intellectual property rights and claims for product liability. As a result, in the future, the Company may be involved in various legal proceedings from time to time.

10. Segment Disclosures

Operating segments are defined as components of an enterprise about which separate discrete information is available for evaluation by the chief operating decision maker, or decision making group, in deciding how to allocate resources in assessing performance. The Company has one reportable segment: life science. The life science segment consists of the development of

clinical and preclinical product candidates for the development of the Company’s proprietary new therapies. The Company’s chief operating decision maker (“CODM”) is the Company's Chief Executive Officer.

The accounting policies of the life science segment are the same as those described in the summary of significant accounting policies. The CODM assesses performance for the life science segment based on net loss. The measure of segment assets is reported on the balance sheet as total consolidated assets. The CODM allocates resources and assesses performance on a consolidated basis, focused on the Company’s cash resources and an assessment of the probability of success of its ongoing research and development activities. Resource allocation decisions are informed by forecasted cash expenditures and actual expenses incurred to date.

To date, the Company has not generated any product revenue. The Company expects to continue to incur significant expenses and operating losses for the foreseeable future as it advances product candidates through all stages of development and clinical trials and, ultimately, seeks regulatory approval.

The table below summarizes the significant expense categories regularly reviewed by the CODM for the three months ended March 31:

Overview

Immunic, Inc. (“Immunic," “we,” “us,” “our” or the "Company") is a late-stage biotechnology company pioneering the development of novel oral therapies for neurologic diseases. We are headquartered in New York City with our research and development operations in Gräfelfing near Munich, Germany. We had approximately 95 employees as of April 30, 2026.

We are pursuing clinical development of orally administered, small molecule programs, each of which has unique features intended to directly address the unmet needs of patients with serious chronic inflammatory and autoimmune diseases. These include the vidofludimus calcium (IMU-838) program, which is in Phase 3 clinical development for patients with relapsing multiple sclerosis (“RMS”), and which has shown therapeutic activity in Phase 2 clinical trials in patients suffering from

relapsing-remitting multiple sclerosis ("RRMS"), progressive multiple sclerosis (”PMS”) and other diseases; the IMU-856 program, which is targeted to regenerate bowel epithelium and restore intestinal barrier function, which could potentially be applicable in numerous gastrointestinal diseases, such as celiac disease, inflammatory bowel disease (“IBD”), and Graft-versus-Host-Disease ("GvHD"); and the IMU-381 program, which comprises next-generation molecules in preclinical testing for neurologic, gastrointestinal and other autoimmune diseases leveraging our nuclear receptor-related 1 (“Nurr1”) platform.

The following table summarizes the potential indications, clinical targets and clinical development status of our three product candidates:

Our most advanced drug candidate, vidofludimus calcium (IMU-838), is being tested in ongoing multiple sclerosis (“MS”) trials as part of its overall clinical development program in order to support potential regulatory approvals for patients with MS in major markets.

The Phase 3 ENSURE program of vidofludimus calcium in RMS, comprising twin studies evaluating efficacy, safety, and tolerability of vidofludimus calcium versus placebo, is currently ongoing. In October 2024, we announced a positive outcome of an interim analysis of the ENSURE program, with an unblinded Independent Data Monitoring Committee ("IDMC") confirming that the predetermined futility criteria have not been met and recommending that both ENSURE trials should continue without changes, including no need for a potential increase of the sample size. In June 2025, we announced completion of enrollment for both ENSURE trials. Each of the trials enrolled adult patients with active RMS at more than 100 sites in 15 countries. In total, 1,121 patients in ENSURE-1 and 1,100 patients in ENSURE-2 have been randomized in a double-blinded fashion to either 30 mg daily doses of vidofludimus calcium or placebo. The top-line data for both ENSURE trials is expected by the end of 2026. Although we currently believe that this goal is achievable, it is dependent on numerous factors, most of which are not under our direct control and can be difficult to predict. We plan to periodically review this assessment and provide updates of material changes as appropriate.

Our Phase 2 CALLIPER trial of vidofludimus calcium in PMS was designed to corroborate vidofludimus calcium’s neuroprotective potential and to evaluate the clinical efficacy, safety and tolerability of vidofludimus calcium in a broad set of PMS patients to determine the suitability of advancing to a confirmatory Phase 3 program. In 2025, we announced the results from the CALLIPER trial, showing substantial and medically relevant reductions in 24-week confirmed disability worsening (“24wCDW”) across patient populations and subgroups without evidence of focal inflammation; substantial and statistically significant data regarding 24-week confirmed disability improvement (“24wCDI”); and reductions in the annualized rate of thalamic brain volume loss and volume of new or enlarging T2 lesions. The data also confirmed the favorable safety and tolerability profile of vidofludimus calcium already observed in previous clinical trials.

If approved, we believe that vidofludimus calcium, with combined neuroprotective, anti-inflammatory, and antiviral effects as well as a favorable safety and tolerability profile, has the potential to be a unique treatment option targeted to the complex pathophysiology of MS. Preclinical data showed that vidofludimus calcium activates the neuroprotective transcription factor Nurr1, which is associated with direct neuroprotective effects and may enhance the potential benefit for patients. Additionally, vidofludimus calcium is a selective inhibitor of the enzyme dihydroorotate dehydrogenase (“DHODH”), which is a key enzyme in the metabolism of overactive immune cells and virus-infected cells. This mechanism is associated with the anti-inflammatory and antiviral effects of vidofludimus calcium. We believe that the combined mechanisms of vidofludimus

calcium are unique in the MS space and support the therapeutic performance observed in our Phase 2 EMPhASIS trial in RRMS patients and in our Phase 2 CALLIPER trial in PMS patients. Vidofludimus calcium has shown a consistent pharmacokinetic, safety and tolerability profile in clinical trials reported, to date, and has already been exposed to more than 3,400 human subjects and patients in either of the drug’s formulations.

IMU-856 is an orally available and systemically acting small molecule modulator that targets Sirtuin 6 (“SIRT6”), a protein which serves as a transcriptional regulator of intestinal barrier function and regeneration of bowel epithelium. Based on preclinical data, we believe this compound may represent a unique treatment approach, as the mechanism of action targets the restoration of the intestinal barrier function and bowel wall architecture in patients suffering from gastrointestinal diseases such as celiac disease, IBD, GvHD and other intestinal barrier function associated diseases. Based on preclinical investigations demonstrating no suppression of immune cells, IMU-856 may have the potential to maintain immune surveillance for patients during therapy, which would be an important advantage versus immunosuppressive medications and may allow the potential for combination with available treatments in multiple gastroenterological diseases.

Data from a Phase 1b clinical trial in celiac disease patients during periods of gluten-free diet and gluten challenge demonstrated positive effects for IMU-856 over placebo in four key dimensions of celiac disease pathophysiology: protection of the gut architecture, improvement of patients’ symptoms, biomarker response, and enhancement of nutrient absorption. IMU-856 was also observed to be safe and well-tolerated in this trial. In a post hoc analysis of this Phase 1b clinical trial, IMU-856 demonstrated a dose-dependent increase of endogenous glucagon-like peptide-1 (“GLP-1”) levels. IMU-856 also showed a dose-dependent reduction of body weight gain and food consumption in preclinical in vivo testing.

We are currently exploring strategic alternatives for the IMU-856 program and are open to discussing potential financing, licensing or partnering options with interested parties.

We have selected the IMU-381 program to leverage our Nurr1 platform for neurologic, gastrointestinal and other autoimmune diseases. The platform comprises next-generation molecules, including a series of chemical derivatives, with improved overall properties. The IMU-381 program is currently in preclinical testing.

Additional research and development activities remain ongoing through preclinical research examining the potential to treat a broad set of neuroinflammatory, autoimmune, and viral diseases with new molecules leveraging our chemical and pharmacological research platform as well as generating intellectual property in these areas. We are also exploring several options to possibly support further development of certain assets and technologies, including a potential spin-off into a new company and potential licensing transactions. Through our wholly-owned subsidiary Gliomic Therapeutics Inc., we are pursuing the use of new compounds in brain cancers leveraging our expertise in DHODH inhibition.

We expect to continue to lead most of our research and development activities from our Gräfelfing, Germany location, where dedicated scientific, regulatory, clinical and medical teams conduct their activities. Due to these teams' key relationships with local and international service providers and academic partners, we anticipate that this should result in more timely and cost-effective execution of our development programs. In addition, we are using our subsidiary in Melbourne, Australia to perform research and development activities in the Australasia region. We also conduct preclinical work in our laboratory in Martinsried, Germany and in Halle/Saale, Germany and through a collaboration with the Fraunhofer Institute.

Our business, operating results, financial condition and growth prospects are subject to significant risks and uncertainties, including delays in clinical trials, the failure of our clinical trials to meet their endpoints, failure to obtain regulatory approval and failure to obtain needed additional funding on acceptable terms, if at all, to complete the development and commercialization of our three development programs.

Strategy

We are focused on the development of new molecules that maximize the therapeutic benefits for patients by uniquely addressing biologically relevant immunological targets. We take advantage of our established research and development infrastructure and operations in Germany and Australia to more efficiently develop our product candidates in indications of high unmet need and where the product candidates have the potential to elevate the standard of care for the benefit of patients. Given the mechanisms of action and the data generated for our product candidates, to date, we continue to execute on the clinical development of our programs for established indications as well as explore additional indications where patients could potentially benefit from the unique profiles of each product candidate.

We are currently focused on maximizing the potential of our development programs through the following strategic initiatives:

•Executing the ongoing Phase 3 ENSURE clinical trials of vidofludimus calcium in RMS.

•Preparation of a Phase 3 clinical program of vidofludimus calcium in primary progressive MS, following the successful completion of the Phase 2 CALLIPER clinical trial in PMS and feedback from healthcare authorities.

•Exploring strategic alternatives for the IMU-856 development program.

•Continuing preclinical research to complement the existing clinical activities, explore additional indications for potential future development and generating additional molecules for potential future development.

•Facilitating readiness for potential commercial launch of our product candidates, if regulatory approvals are received, through targeted and stage-appropriate pre-commercial activities.

•Evaluating potential strategic collaborations for each product candidate in order to complement our existing research and development capabilities and to facilitate potential commercialization of these product candidates by taking advantage of the resources and capabilities of strategic collaborators in order to enhance the potential and value of each product candidate.

Liquidity and Financial Condition

Immunic has no products approved for commercial sale and has not generated any revenue from product sales. We have never been profitable and have incurred operating losses in each year since inception in 2016. The Company has an accumulated deficit of approximately $641.2 million as of March 31, 2026 and $608.6 million as of December 31, 2025. Substantially all of our operating losses resulted from expenses incurred in connection with our research and development programs and from general and administrative costs associated with our operations.

We expect to incur significant expenses and increasing operating losses for the foreseeable future as we initiate and continue the development of our product candidates and add personnel necessary to advance our pipeline of product candidates. We expect that our operating losses will fluctuate significantly from quarter-to-quarter and year-to-year due to timing of development programs.

The pro rata share for each Participating Series B Holder is equal to the number of Series B Warrants exchanged by such Participating Series B Holder divided by the number of Series B Warrants exchanged by all Participating Series B Holders (expressed as a percentage). Royalty Interests will be due and payable quarterly by the Company to the Participating Series B Holders following the First Commercial Sale (as defined in the Royalty Exchange Agreement). The Company determined that the Royalty Interests do not meet the criteria for recognition as a liability. The Company will recognize amounts payable under the Royalty Interests when they become probable and estimable.

Changes to the Board of Directors – Resignation of Director

On February 12, 2026, Maria Törnsén resigned as a member of the Board in connection with the February Offering. The resignation of Ms. Törnsén was not the result of any disagreement with the Company on any matter relating to the Company’s operations, policies, or practices. The Board and the Company are deeply grateful for Ms. Törnsén’s service, dedication, and contributions to the Company.

CEO Search

Our Co-Founder and Chief Executive Officer, Dr. Daniel Vitt, and the Board have begun a search for a new CEO with deep commercial expertise in the MS space to lead Immunic through its next stage of growth and into commercialization. Subsequently, Dr. Vitt plans to transition to a new senior executive role focused on strengthening the Company's scientific strategy and driving portfolio advancement. He will continue to support the organization in this capacity and as a member of the Board of Directors.

Regained Compliance with Nasdaq Minimum Bid Price Requirement

On April 1, 2026, we announced that we received written notice from the Listing Qualifications Department of The Nasdaq Stock Market LLC ("Nasdaq") on March 27, 2026, informing us that we have regained compliance with the minimum bid price requirement under Nasdaq Listing Rule 5550(a)(2) for continued listing on The Nasdaq Capital Market.

According to the Notice, we have regained compliance with the minimum bid price requirement, because the closing bid price of our common stock was at $1.00 per share or greater for at least 20 consecutive business days, satisfying the Nasdaq requirement on March 26, 2026. As a result, the matter was closed.

Jon Congleton Joined the Board of Directors

On March 31,2026, we announced the appointment of Jon Congleton, a seasoned biopharmaceutical executive with nearly 40 years of experience spanning drug development, commercialization and corporate leadership, to our Board of Directors, effective March 27, 2026. In connection with his appointment as a director, Mr. Congleton received an inaugural grant of options to purchase up to a total of 50,000 shares of the Company’s common stock, effective March 27, 2026, which vest on a monthly basis over a three-year period.

Grant of Key European Patent Protecting Relevant Dosing Regimens for Vidofludimus Calcium

On March 10, 2026, we announced that the European Patent Office (“EPO”) has granted a key European patent, EP3713554, directed to label-relevant dosing regimens of vidofludimus calcium. The patent is expected to provide protection for vidofludimus calcium in Europe into 2038, and may be eligible for a Supplementary Protection Certificate (SPC), which could extend market exclusivity potentially into 2043. This patent was previously granted by the United States Patent and Trademark Office (USPTO) in 2023.

The claims broadly protect vidofludimus and its salt, solvate and free acid forms, in all label-relevant dosing regimens. This protection extends beyond a specific salt form, meaning that even alternative salts or forms will fall within the scope of the patent if used according to the label.

Presented Additional Phase 2 CALLIPER Trial Data for Vidofludimus Calcium at the ACTRIMS Forum 2026

On February 4, 2026, we announced the presentation of additional data from our Phase 2 CALLIPER trial of vidofludimus calcium in patients with PMS at the Americas Committee for Treatment and Research in Multiple Sclerosis (“ACTRIMS”) Forum 2026. The findings presented in two poster presentations provide additional evidence of vidofludimus calcium’s effects on key biological drivers of disease progression, including antiviral immune responses linked to Epstein-Barr virus (“EBV”) and magnetic resonance imaging (“MRI”) markers of both acute-focal and chronic-compartmentalized inflammation. The findings further reinforce our belief that vidofludimus calcium has the potential to address underlying mechanisms of disease progression in MS patients.

Retention Bonus Agreement

On April 7, 2026, we entered into a Retention Bonus Agreement with Daniel Vitt, Ph.D., our Chief Executive Officer. The Agreement was entered into in connection with our commencement of a search for a new Chief Executive Officer, and Dr. Vitt’s potential transition to a “C-Suite” role that is focused on strengthening our scientific strategy and driving portfolio advancement after a new Chief Executive Officer is hired.

If the Company terminates Dr. Vitt's employment without "Cause" or Dr. Vitt resigns for "Good Reason" prior to the Retention Date, the Company will pay the Retention Bonus within five (5) days of such termination or resignation, as applicable. If the Retention Bonus is paid, the amount will be credited against any cash severance payment that would otherwise become due under the U.S. Employment Agreement or the Service Agreement dated December 18, 2023, by and between Dr. Vitt and Immunic AG, as a result of any involuntary termination of employment.

Appointment of Michael A. Panzara, M.D., M.P.H., as Chief Medical Officer

Effective April 24, 2026, Michael A. Panzara, M.D., M.P.H., was appointed as our Chief Medical Officer. Dr. Panzara will lead our development organization, including clinical development, medical affairs, and regulatory affairs, and will be a critical partner to the Chief Executive Officer and the Board of Directors in defining and driving the overall company strategy. Dr. Panzara brings over 25 years of global neurology experience to Immunic. Dr. Panzara succeeds Andreas Muehler, M.D., M.B.A.

In connection with his appointment as Chief Medical Officer, Dr. Panzara entered into an employment agreement with the Company, dated as of April 24, 2026 (the “Panzara Employment Agreement”). Pursuant to the Panzara Employment Agreement, Dr. Panzara will receive a yearly base salary of $600,000, subject to periodic review and adjustments made by the Company, and be eligible for a yearly bonus amount of not less than 50% of the yearly base salary upon achievement of certain individual and company goals.

On April 23, 2026, effective April 24, 2026, the Compensation Committee of the Board approved a grant to Dr. Panzara of an initial equity option to purchase 300,000 shares of common stock of the Company under the Immunic, Inc. 2026 Inducement Equity Compensation Plan (the “Panzara Options”). The Panzara Options were granted as an inducement material to Dr. Panzara’s commencement of employment pursuant to NASDAQ Listing Rule 5635(c)(4). The Panzara Options will be time vested, with one half vesting on the one-year anniversary of April 24, 2026 and one half vesting in equal monthly installments over a period of twenty-four (24) months thereafter. The exercise price of the options is the closing price of the Company’s common stock on the date the Panzara Options were approved by the Compensation Committee.

Resignation of Andreas Muehler, M.D., M.B.A.

On April 27, 2026, Andreas Muehler, M.D., M.B.A., resigned as the Chief Medical Officer of the Company. The resignation of Dr. Muehler was not the result of any disagreement with the Company on any matter relating to the Company’s operations, policies, or practices. The Board and the Company are deeply grateful for Dr. Muehler’s service, dedication, and contributions to the Company.

In connection with Dr. Muehler’s resignation as Chief Medical Officer, the Company entered into a Transition, Separation, and Consulting Agreement with Dr. Muehler, dated April 27, 2026 (the “Separation Agreement”). Pursuant to the Separation Agreement, Dr. Muehler’s employment with the Company as Chief Medical Officer terminated on April 27, 2026, and Dr. Muehler’s title was changed to Senior Medical Officer. Dr. Muehler also agreed to resign from the Executive Board of Immunic AG, a wholly owned subsidiary of the Company, on or before April 30, 2026 (the “Separation Date”). Dr. Muehler served as Senior Medical Officer through the Separation Date. From the date of the Separation Agreement to the Separation Date, (a) the Company agreed to pay Dr. Muehler all accrued salary earned through the Separation Date, subject to standard payroll deductions and withholdings, and (b) Immunic AG agreed to pay Dr. Muehler all accrued salary earned under the service agreement dated December 18, 2023, by and between Immunic AG and Dr. Muehler (the “Service Agreement”), through the Separation Date, subject to standard payroll deductions and withholdings.

Additionally, 100% of Dr. Muehler’s outstanding equity awards vested as of the Separation Date. Dr. Muehler will have three (3) years following Separation Date to exercise any vested equity awards

Components of Results of Operations

Revenue

To date, we have not generated any revenue from product sales and do not expect to generate any revenue from the sale of products in the foreseeable future. If our development efforts for our product candidates are successful and result in regulatory approval, we may generate revenue in the future from product sales. We cannot predict if, when, or to what extent we will generate revenue from the commercialization and sale of our product candidates. We may never succeed in obtaining regulatory approval for any of our product candidates or achieving market acceptance and commercial success for any product that does receive regulatory approval.

Research and Development Expenses

Research and development expenses consist of costs associated with our research activities, including our product discovery efforts and the development of our product candidates. Our research and development expenses include:

•external research and development expenses and milestone payments incurred under arrangements with third parties, such as contract research organizations, contract manufacturing organizations, collaborations with partners, consultants, and our scientific advisors; and

•internal personnel expenses.

We expense research and development costs as incurred. Non-refundable advance payments for goods and services that will be used in future research and development activities are capitalized as prepaid expenses and expensed when the service has been performed or when the goods have been received.

Since our inception in March 2016, we have spent a total of approximately $485.6 million in research and development expenses through March 31, 2026.

These costs primarily include external development expenses and internal personnel expenses for the three development programs, vidofludimus calcium, IMU-856 and IMU-381. We have spent the majority of our research and development resources on vidofludimus calcium, our lead development program, for clinical trials in MS and UC.

Our research and development expenses are expected to increase in the foreseeable future as we continue to conduct ongoing research and development activities, initiate new preclinical and clinical trials and build our pipeline of product candidates. Our research and development expenses may also increase in the foreseeable future due to the current inflationary environment as well as supply chain shortages and tariffs, which result in increased costs. The process of conducting clinical trials and preclinical studies necessary to obtain regulatory approval is costly and time consuming. We may never succeed in achieving regulatory approval for any of our product candidates.

Successful development of product candidates is highly uncertain and may not result in approved products. Completion dates and completion costs can vary significantly for each product candidate and are difficult to predict. We anticipate that we will make determinations as to which programs to pursue and how much funding to direct to each program on an ongoing basis in response to the development and regulatory success of each product candidate, and ongoing assessments as to each product candidate’s commercial potential.

General and Administrative Expenses

General and administrative expenses consist primarily of personnel expenses, professional fees for legal, accounting, tax and business consulting services, insurance premiums and stock-based compensation.

Other Income (Expense)

Interest Income

Interest income consists of interest earned on our money market funds and bank accounts which are a portion of our cash and cash equivalents balance.

Other Income (Expense), Net

Other income (expense) primarily consists of a German Government research and development grant in 2025.

Results of Operations

Comparison of the Three Months Ended March 31, 2026 and 2025

The following table summarizes our operating expenses for the three months ended March 31, 2026 and 2025:


	Three Months Ended March 31,				Change
	2026		2025		$		%
(dollars in thousands)	(unaudited)
Operating expenses:
Research and development	$	25,626	$	21,533	$	4,093	19	%
General and administrative	7,609		5,292		2,317		44	%
Total operating expenses	$	33,235	$	26,825	$	6,410	24	%
Loss from operations	(33,235)		(26,825)		(6,410)		24	%
Other income:
Interest income	760		183		$	577	315	%

Other income (expense), net	(113)		1,169		$	(1,282)	(110)	%
Total other income	647		1,352		$	(705)	(52)	%
Net loss	$	(32,588)	$	(25,473)	$	(7,115)	28	%

Research and development expenses increased by $4.1 million during the three months ended March 31, 2026, as compared to the three months ended March 31, 2025. The increase reflects (i) a $2.9 million increase in external development costs related to the vidofludimus calcium program, (ii) a $1.0 million increase in personnel expenses, $0.7 million of which was related to non-cash stock compensation and (iii) a $0.2 million increase related costs across numerous categories.

General and administrative expenses increased by $2.3 million during the three months ended March 31, 2026, as compared to the three months ended March 31, 2025. The increase was due to (i) a $2.0 million increase related to personnel expenses, of which $1.8 million was related to non-cash stock compensation, (ii) a $0.2 million increase in legal and consultancy expenses, (iii) a $0.2 million increase in marketing expenses, which was partially offset by a $0.1 million decrease related to costs across numerous categories.

Interest income increased $0.6 million during the three months ended March 31, 2026 as compared to the three months ended March 31, 2025. This is due to a higher average cash balance as a result of the February 2026 Private Placement.

Other income (expense) decreased by $1.3 million during the three months ended March 31, 2026, as compared to the three months ended March 31, 2025. The decrease was primarily attributable to (i) a $1.1 million grant income of the German Federal Ministry of Finance recognized in the first quarter 2025 and no grant income in 2026 and (ii) a $0.2 million decrease across numerous categories.

Liquidity and Capital Resources

Liquidity and Financial Condition

We have no products approved for commercial sale and have not generated any revenue from product sales. We have never been profitable and have incurred operating losses in each year since inception in 2016. We have an accumulated deficit of approximately $641.2 million as of March 31, 2026 and $608.6 million as of December 31, 2025. Substantially all of our operating losses resulted from expenses incurred in connection with our research and development programs and from general and administrative costs associated with our operations.

We expect to continue to incur significant expenses and increasing operating losses for the foreseeable future as we initiate and continue the preclinical and clinical development of our product candidates and add personnel necessary to operate as a company with an advanced clinical pipeline of product candidates. To the extent additional funds are necessary to meet long-term liquidity needs as we continue to execute our business strategy, we anticipate that they will be obtained through the incurrence of indebtedness, additional equity financings, product licensing or a combination of these potential sources of funds, although we can provide no assurance that these sources of funding will be available on reasonable terms, if at all.

From inception through March 31, 2026, we have raised net cash of approximately $684.9 million from private and public offerings of preferred stock, common stock, prefunded warrants and tranche rights. As of March 31, 2026, we had cash and cash equivalents of approximately $186.6 million. With these funds we expect to be able to fund our operations beyond twelve months from the date of the issuance of the accompanying consolidated financial statements.

In November 2023, we filed a shelf registration statement on Form S-3 (the "2023 Shelf Registration Statement"). The 2023 Shelf Registration Statement permits the offering, issuance and sale of up to $250.0 million of common stock, preferred stock, warrants, debt securities, and/or units in one or more offerings and in any combination of the foregoing. The 2023 Registration Statement was declared effective on May 31, 2024. Unsold securities from the expired 2020 Shelf Registration Statement can continue to be sold under the 2023 Shelf Registration Statement. As a result of the April 2025 Offering and May 2025 Offering, the total amount available under the 2023 Shelf Registration Statement was reduced by $70.1 million to $262.2 million as of March 31, 2026. The Company can also use the unused amount (currently $80 million) of the available ATM as additional shelf availability.

We agreed to pay Leerink Partners LLC a commission equal to 3.0% of the gross proceeds from the sales of common shares pursuant to the May 2024 ATM and have agreed to provide Leerink Partners LLC with customary indemnification and contribution rights.

We did not have any ATM activity during the three months ended March 31, 2026 and 2025.

May 2025 Equity Offering

Future Capital Requirements

As noted above, we have not generated any revenue from product sales and we do not know when, or if, we will generate any revenue from product sales. We will not be able to generate any revenue from product sales unless and until we obtain

regulatory approval for and commercialize any of our product candidates. We expect our expenses to continue to increase as we continue the ongoing research, development, manufacture and clinical trials of, and seek regulatory approval for, our product candidates. We also incur additional costs associated with operating as a public company. In addition, subject to obtaining regulatory approval of any of our product candidates, we anticipate that we will need substantial additional funding in connection with our continuing operations.

Our future expenses and capital requirements are difficult to forecast and will depend on many factors, including, but not limited to:

•the timing and structure of any strategic options and transactions, if any;

•personnel-related expenses, including salaries, benefits, stock-based compensation expense and other compensation expenses related to retention and termination of personnel;

•the scope, progress, duration, results and costs of research and development and ongoing clinical trials;

•the cost and timing of future regulatory submissions;

•the cost and timing of developing and validating the manufacturing processes for any potential product candidates;

•the cost and timing of any commercialization activities, including reimbursement, marketing, sales and distribution costs;

•our ability to establish new collaborations, licensing or other arrangements and the financial terms of such agreements;

•the number and characteristics of any future product candidates we pursue;

•the costs involved with being a public company;

•the costs involved in preparing, filing, prosecuting, maintaining, defending and enforcing patents, including litigation costs and the outcome of such litigation;

•the cost, timing and outcome of any future litigation; and

•the timing, receipt and amount from the sales of, or royalties on, any future products.

Until such time, if ever, as we can generate substantial product revenues, we expect to finance our cash needs through a combination of stock offerings, debt financings, strategic alliances, collaborations and licensing arrangements. We do not expect to achieve revenue from product sales prior to the use of all the net proceeds from our public and private offerings to date. We do not have any committed external source of funds. Additional funds may not be available on acceptable terms, if at all. To the extent that we raise additional capital through the sale of equity securities, the ownership interest of our stockholders will be diluted and it may be on terms that are not favorable to us or our stockholders. Sales of equity securities will also be more difficult for at least the foreseeable future because of general volatility in the equity markets for companies like us. Debt financing, if available, may involve covenants restricting our operations or our ability to incur additional debt or other terms that are not favorable to us or our stockholders. Also, the cost of debt financing has increased due to the rise in interest rates over the past few years. If we raise additional funds through collaborations and licensing arrangements with third parties, we would expect to relinquish substantial rights to our technologies or our future products, or grant licenses on terms that may not be favorable to us. If we were to complete a merger, or other business combination, we may relinquish all control over the organization and could experience detrimental tax effects. If we are unable to raise adequate funds, we may have to curtail our product development programs and liquidate some or all of our assets. Any of these factors could harm our operating results and could result in substantial declines in the trading price of our common stock.

As of March 31, 2026, we had approximately $186.6 million in cash and cash equivalents.

Cash Flows

The following table shows a summary of our cash flows for the three months ended March 31, 2026 and 2025:


	Three Months Ended March 31,
	2026		2025
(in thousands)	(unaudited)
Cash (used in) provided by:
Operating activities	$	(17,301)	$	(21,776)

Financing activities	$	188,642	$	—

Operating activities

During the three months ended March 31, 2026, operating activities used $17.3 million of cash. The use of cash primarily resulted from our net loss of $32.6 million adjusted for non-cash charges of $4.7 million primarily related to stock-based compensation of $4.5 million and non-cash lease expense of $0.2 million and a $10.6 million net increase in our operating assets and liabilities.

During the three months ended March 31, 2025, operating activities used $21.8 million of cash. The use of cash primarily resulted from (i) our net loss of $25.5 million adjusted for non-cash charges of $2.2 million related to $2.0 million for stock-based compensation, $0.1 million related to non-cash lease expense, and $0.1 million related to depreciation and (ii) a $1.5 million net increase in our operating assets and liabilities.

Legal Proceedings

Critical Accounting Policies and Estimates

Our unaudited condensed consolidated financial statements are prepared in conformity with U.S. GAAP. The preparation of our unaudited condensed consolidated financial statements and related disclosures requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, costs and expenses, and the disclosure of contingent assets and liabilities in our financial statements. We base our estimates on historical experience, known trends and events and various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. We evaluate our estimates and assumptions on an ongoing basis. Our actual results may differ from these estimates under different assumptions or conditions. We have reviewed these critical accounting policies and related disclosures with the Audit Committee of our Board.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Interest Rate Sensitivity

We had cash and cash equivalents and investments of $186.6 million as of March 31, 2026, which were held for working capital purposes. We do not enter into investments for trading or speculative purposes. We do not believe that we have any material exposure to changes in the fair value of these investments as a result of changes in interest rates due to their short-term nature. Decreases or increases in interest rates, however, will reduce or increase future investment income, respectively, to the extent we have funds available for investment.

Foreign Currency Exchange Risk

Our primary research and development operations are conducted in our facilities in Germany. We have entered into and may continue to enter into international agreements, primarily related to our clinical studies. Accordingly, we have exposure to foreign currency exchange rates and fluctuations between the U.S. dollar and foreign currencies, primarily the Euro and the Australian dollar, which could adversely affect our financial results, including income and losses as well as assets and liabilities. To date, we have not entered into, and do not have any current plans to enter into, any foreign currency hedging transactions or derivative financial transactions. Our exposure to foreign currency risk will fluctuate in future periods as our research and clinical development activities in Europe and Australia change. We currently maintain a significant amount of our assets outside of the U.S.

The functional currencies of our foreign subsidiaries are the applicable local currencies. Accordingly, the effects of exchange rate fluctuations on the net assets of these operations are accounted for as translation gains or losses in accumulated other comprehensive income (loss) within stockholders’ equity (deficit). Foreign currency transaction gains and losses related to long-term intercompany loans that are payable in the foreseeable future are recorded in Other Income (Expense). Our German subsidiary is currently a significant portion of our business and, accordingly, a change of 10% in the currency exchange rates, primarily the Euro, could have a material impact on our financial position or results of operations.

Although operating in local currencies may limit the impact of currency rate fluctuations on the results of operations of our German and Australian subsidiaries, rate fluctuations may impact the consolidated financial position as the assets and liabilities of our foreign operations are translated into U.S. dollars in preparing our consolidated balance sheets. As of March 31, 2026, our German and Australian subsidiaries had net current assets (defined as current assets less current liabilities), subject to foreign currency translation risk, of $18.2 million. A change of approximately $1.8 million in net current assets would result as of March 31, 2026, from a hypothetical 10% adverse change in quoted foreign currency exchange rates, primarily due to the Euro. In addition, a 10% change in the foreign currency exchange rates for the three months ended March 31, 2026, would have impacted our net loss by approximately $2.5 million, primarily due to the Euro.

Effects of Inflation and Tariffs

We have experienced a general increase in costs as a result of global inflation, however, we do not believe that inflation and changing prices had a material impact on our results of operations for any periods presented herein. We do not believe that currently enacted or proposed tariffs will have a material impact on our operations going forward, but the actual

impact of potential or unannounced tariffs are not knowable at this time.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

An evaluation was carried out, under the supervision of and with the participation of our management, including our Chief Executive Officer and our Principal Financial Officer, of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15 (e)) under the Securities Exchange Act of 1934, as amended ("the Exchange Act"), as of the end of the period covered by this Quarterly Report. Based on such evaluation, our Chief Executive Officer and our Principal Financial Officer have concluded that as of March 31, 2026 our disclosure controls and procedures are effective to ensure that the information required to be disclosed by us in the reports we file or submit under the Exchange Act was recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.

Changes in Internal Control over Financial Reporting

There was no change in our internal control over financial reporting that occurred during the quarter ended March 31, 2026 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Part II - OTHER INFORMATION

Item 1. Legal Proceedings

We are not currently a party to any litigation, nor are we aware of any pending or threatened litigation against us, that we believe would materially affect our business, operating results, financial condition or cash flows. Our industry is characterized by frequent claims and litigation including securities litigation, claims regarding patent and other intellectual property rights and claims for product liability. As a result, in the future, we may be involved in various legal proceedings from time to time.

Item 1A. Risk Factors

You should carefully consider the risk factors included in Item 1A. of the 2025 Annual Report and the other information in this Quarterly Report, including the section of this Quarterly Report titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and our financial statements and related notes. If any of the events described in our 2025 Annual Report, and elsewhere in this Quarterly Report occur, our business, operating results and financial condition could be seriously harmed. This Quarterly Report also contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those anticipated in the forward-looking statements as a result of factors that are described in our 2025 Annual Report and elsewhere in this Quarterly Report.
