Clene Inc. (CLNN) posts larger Q1 2026 loss and flags going concern
Rhea-AI Filing Summary
Clene Inc. reported a net loss of $8.1 million for the quarter ended March 31, 2026, compared with $0.8 million a year earlier. Revenue was minimal at $15,000, down from $81,000, reflecting its early-stage status.
Operating loss improved to $2.1 million from $4.1 million as research and development and general and administrative expenses fell sharply, but large non-cash items, including a $4.6 million loss on the initial issuance of equity and higher warrant-related charges, drove the larger bottom-line loss.
Cash and cash equivalents were $5.9 million as of March 31, 2026, with net cash used in operating activities of $4.5 million in the quarter. Total liabilities of $40.5 million exceeded total assets of $21.7 million, resulting in a stockholders’ deficit of $18.8 million. The company discloses substantial doubt about its ability to continue as a going concern within 12 months without additional financing, despite raising $6.0 million during the quarter and $7.0 million shortly thereafter through registered direct equity offerings.
Positive
- None.
Negative
- Substantial doubt about going concern: Management states the company does not expect to have sufficient cash to sustain operations for 12 months without additional financing and concludes that its plans do not alleviate substantial doubt about its ability to continue as a going concern.
- Weak equity position and leverage: As of March 31, 2026, total liabilities of $40.5 million exceed assets of $21.7 million, resulting in a stockholders’ deficit of $18.8 million, alongside over $19 million of notes and convertible notes payable.
- High cash burn relative to cash balance: Cash and cash equivalents of $5.9 million compare with net cash used in operating activities of $4.5 million for the quarter, indicating limited runway absent further capital raises.
- Complex and costly financing structures: The quarter includes a $4.6 million loss on initial issuance of equity and $5.9 million of new warrant liabilities, adding volatility and cost to capital while increasing common stock warrant liabilities to $12.0 million.
Insights
Heavy losses, high leverage, and a formal going concern warning dominate this quarter.
Clene remains an early-stage biotech with negligible revenue of $15,000 and a quarterly net loss of $8.1 million. While operating expenses fell meaningfully year over year, non‑cash costs from warrant and derivative structures and a $4.6 million loss on equity issuance deepened reported losses.
The balance sheet is highly leveraged: total liabilities of $40.5 million sit against assets of $21.7 million, producing a stockholders’ deficit of $18.8 million. Notes payable and convertible notes total more than $19 million, and common stock warrant liabilities and derivative liabilities add over $14 million of fair value obligations.
Cash and cash equivalents were $5.9 million with operating cash outflow of $4.5 million in the quarter. Management explicitly states there is substantial doubt about continuing as a going concern and highlights a covenant requiring at least $2.0 million of unrestricted cash on the senior secured convertible notes. Recent equity raises of $6.0 million during the quarter and $7.0 million after quarter-end provide temporary liquidity but do not remove that going concern language.

CAUTIONARY NOTE REGARDING FORWARD LOOKING STATEMENTS
Certain statements in this Quarterly Report on Form 10-Q (“Quarterly Report”) may constitute “forward-looking statements” for purposes of the federal securities laws. Our forward-looking statements include, but are not limited to, statements regarding our or our management team’s expectations, hopes, beliefs, intentions or strategies regarding our future operations. In addition, any statements that refer to projections, forecasts or other characterizations of future events or circumstances, including any underlying assumptions, are forward-looking statements. The words “anticipate,” “believe,” “contemplate,” “continue,” “could,” “estimate,” “expect,” “intends,” “may,” “might,” “plan,” “possible,” “potential,” “predict,” “project,” “should,” “will,” “would” and similar expressions may identify forward-looking statements, but the absence of these words does not mean that a statement is not forward-looking. Forward-looking statements in this Quarterly Report may include, for example, statements about:
| ● |
our future financial performance, including our ability to continue as a going concern; |
| ● |
our plans and strategies to raise additional funding; |
| ● |
the clinical results of our drug candidates; |
| ● |
the likelihood of commercial success for our drug candidates; |
| ● |
our plans and strategies to obtain and maintain regulatory approvals of our drug candidates; |
| ● |
the size and growth potential of the markets for our drug candidates, and our ability to serve those markets, either alone or in combination with others; |
| ● |
changes in the market for our drug candidates; |
| ● |
expansion plans and opportunities; and |
| ● |
any other statements that address events or developments that we intend or believe will or may occur in the future. |
These forward-looking statements represent our views as of the date of this Quarterly Report and involve a number of judgments, risks and uncertainties. We anticipate that subsequent events and developments will cause our views to change. We undertake no obligation to update forward-looking statements to reflect events or circumstances after the date they were made, whether as a result of new information, future events or otherwise, except as may be required under applicable securities laws. Accordingly, forward-looking statements should not be relied upon as representing our views as of any subsequent date.
As a result of a number of known and unknown risks and uncertainties, our actual results or performance may be materially different from those expressed or implied by these forward-looking statements. Some factors that could cause actual results to differ include:
| ● |
our substantial dependence on the successful commercialization of our drug candidates, if approved, in the future; |
| ● |
our significant net losses and net operating cash outflows; |
| ● |
our ability to demonstrate the efficacy and safety of our drug candidates; |
| ● |
the clinical results for our drug candidates, which may not support further development or marketing approval; |
| ● |
actions of regulatory agencies, which may affect the initiation, timing, and progress of clinical trials and marketing approval; |
| ● |
our ability to achieve commercial success for our drug candidates, if approved; |
| ● |
our ability to obtain and maintain protection of intellectual property for our technology and drug candidates; |
| ● |
our reliance on third parties to conduct research, drug development, and other services; |
| ● |
our limited operating history and our ability to obtain additional funding for operations and to complete the licensing or development and commercialization of our drug candidates; |
| ● |
the impact of any future epidemics, pandemics, or conflicts; |
| ● |
changes in applicable laws or regulations; |
| ● |
the effects of inflation; |
| ● |
the effects of staffing and materials shortages; |
| ● |
the possibility that we may be adversely affected by other economic, business, and/or competitive factors; and |
| ● |
other risks and uncertainties set forth in the section entitled “Risk Factors” in our most recent Annual Report on Form 10-K and any subsequent Quarterly Reports on Form 10-Q. |
In addition, statements that “we believe” and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based upon information available to us as of the date of this Quarterly Report, and while we believe such information forms a reasonable basis for such statements, such information may be limited or incomplete, and our statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all potentially available relevant information. These statements are inherently uncertain and you are cautioned not to rely unduly upon these statements.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Note 1. Nature of the Business
Clene Inc. (the “Company,” “we,” “us,” or similar such references) is a clinical-stage pharmaceutical company pioneering the discovery, development, and commercialization of novel clean-surfaced nanotechnology therapeutics. We have developed an electro-crystal-chemistry drug development platform that enables production of concentrated, stable, highly active, clean-surfaced nanocrystal suspensions. We have multiple drug assets currently in development for applications primarily in neurology. Our efforts are currently focused on addressing the high unmet medical needs in central nervous system disorders including amyotrophic lateral sclerosis (“ALS”), multiple sclerosis (“MS”), and Parkinson’s disease (“PD”). Our patented electro-crystal-chemistry manufacturing platform further enables us to develop very low concentration dietary supplements to advance the health and well-being of broad populations. These dietary supplements can vary greatly and include nanocrystals of varying composition, shapes and sizes as well as ionic solutions with diverse metallic constituents. Dietary supplements are marketed and distributed through our wholly-owned subsidiary, dOrbital, Inc., or through 4Life Research LLC (“4Life”), a related party (see Note 8 and Note 15).
Going Concern
We incurred a loss from operations of $
We have incurred significant losses and negative cash flows from operations since our inception. We have not generated significant revenue since our inception, and we do not anticipate generating significant revenue unless we successfully complete development and obtain regulatory approval for commercialization of a drug candidate. We expect to incur additional losses in the future, particularly as we advance the development of our clinical-stage drug candidates, continue research and development of our preclinical drug candidates, and initiate additional clinical trials of, and seek regulatory approval for, these and other future drug candidates. We expect that within the next twelve months, we will not have sufficient cash and other resources on hand to sustain our current operations or meet our obligations as they become due unless we obtain additional financing. Additionally, pursuant to our senior secured convertible promissory notes issued in December 2024 (the “2024 SSCP Notes”), we are required to maintain unrestricted cash and cash equivalents of at least $
To mitigate our funding needs, we plan to raise additional funding, including exploring equity financing and offerings, debt financing, licensing or collaboration arrangements with third parties, as well as utilizing our existing at-the-market facility and potential proceeds from the exercise of outstanding warrants and stock options. These plans are subject to market conditions and reliance on third parties, and there is no assurance that effective implementation of our plans will result in the necessary funding to continue current operations. During the three months ended March 31, 2026, we raised $
The accompanying condensed consolidated financial statements have been prepared assuming we will continue as a going concern, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. As a result, the accompanying condensed consolidated financial statements do not include any adjustments relating to the recoverability and classification of assets and their carrying amounts, or the amounts and classification of liabilities that may result should we be unable to continue as a going concern.
Note 2. Summary of Significant Accounting Policies
Basis of Presentation
The accompanying condensed consolidated financial statements include the accounts of Clene Inc. and our wholly-owned subsidiaries, Clene Nanomedicine, Inc. (“Clene Nanomedicine”), a subsidiary incorporated in Delaware, Clene Australia Pty Ltd (“Clene Australia”), a subsidiary incorporated in Australia, Clene Netherlands B.V. (“Clene Netherlands”), a subsidiary incorporated in the Netherlands, and dOrbital, Inc., a subsidiary incorporated in Delaware, after elimination of all intercompany accounts and transactions. We have prepared the accompanying condensed consolidated financial statements in accordance with United States (“U.S.”) Generally Accepted Accounting Principles (“GAAP”) for interim financial reporting and as required by Regulation S-X, Rule 10-01. The condensed consolidated financial statements have been prepared on the same basis as our audited annual consolidated financial statements and, in the opinion of management, reflect all adjustments, which are normal and recurring in nature, necessary for fair financial statement presentation. The financial data and other information disclosed in the condensed consolidated financial statements and related notes for the three months ended March 31, 2026 and 2025 are unaudited.
Results of operations for the three months ended March 31, 2026 and 2025 are not necessarily indicative of the results for the entire fiscal year or any other period. The condensed consolidated financial statements for the three months ended March 31, 2026 and 2025 should be read in conjunction with the audited consolidated financial statements included in our Annual Report on Form 10-K.
Use of Estimates
The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, and disclosure of contingent assets and liabilities, and the reported amounts of expenses. We base our estimates on historical experience and various other assumptions that we believe to be reasonable. Actual results may differ from those estimates or assumptions. Estimates are periodically reviewed in light of changes in circumstances, facts, and experience, and any changes in estimates will be recorded in future periods as they develop.
Risks and Uncertainties
We are subject to certain risks and uncertainties and believe that changes in any of the following areas could have a material adverse effect on future financial condition, results of operations, or cash flows: ability to obtain additional financing; regulatory approval and market acceptance of, and reimbursement for, product candidates; performance of third-party contract research organizations (“CROs”) and clinical vendors upon which we rely; protection of our intellectual property; litigation or claims against us based on intellectual property, patent, product, regulatory, or other factors; and our ability to attract and retain employees necessary to support our growth. The product candidates we develop require approvals from regulatory agencies prior to commercial sales. There can be no assurance that our current and future product candidates will receive the necessary approvals or be commercially successful. If we are denied approval or approval is delayed, it will have a material adverse impact on our business and our condensed consolidated financial statements.
Concentrations of Credit Risk
Financial instruments that potentially subject us to significant concentrations of credit risk consist primarily of cash. Our cash is held in financial institutions and amounts on deposit may at times exceed federally insured limits. We have not experienced any losses on our deposits of cash and do not believe that we are subject to unusual credit risk beyond the normal credit risk associated with commercial banking relationships.
Cash and Cash Equivalents
We consider all short-term investments with original maturities of 90 days or less when purchased to be cash equivalents.
Restricted Cash
We classify cash as restricted when it is unavailable for withdrawal or use in our general operating activities. Restricted cash is classified as current and noncurrent on the condensed consolidated balance sheets based on the nature of the restriction. Our restricted cash balance includes contractually restricted deposits related to our corporate credit card.
Inventory
Inventory is stated at historic cost on a first-in first-out basis. Our inventory consisted of $
Property and Equipment
Property and equipment are stated at cost less accumulated depreciation. Property and equipment consist of laboratory and office equipment, computer software, and leasehold improvements. Depreciation is calculated using the straight-line method over the estimated economic useful lives of the assets, which are
We capitalize costs to obtain or develop computer software for internal use, including development costs incurred during the software development stage and costs to obtain software for access and conversion of historical data. We also capitalize costs to modify, upgrade, or enhance existing internal-use software that result in additional functionality. We expense costs incurred during the preliminary project stage, training costs, data conversion costs, and maintenance costs.
Debt
When debt is issued and a derivative is required to be separated (e.g., bifurcated conversion option) or another separate freestanding financial instrument (e.g., warrant) is issued, costs and fees incurred are allocated to the instruments issued (or bifurcated) in proportion to the allocation of proceeds. When some portions of the costs and fees relate to a bifurcated derivative or freestanding financial instrument that is being subsequently measured at fair value, those allocated costs are expensed immediately. Debt discounts, debt premiums, and debt issuance costs related to debt are recorded as deductions that net against the principal value of the debt and are amortized to interest expense over the contractual term of the debt using the effective interest method.
In accordance with ASC 470-20, Debt with Conversion and Other Options, when we issue debt with warrants, we treat the warrants as a debt discount, recorded as a contra-liability against the debt, and amortize the balance over the life of the underlying debt as interest expense in the condensed consolidated statements of operations and comprehensive loss. The offset to the contra-liability is recorded as additional paid-in capital in the condensed consolidated balance sheets if the warrants are not treated as a derivative or liability under ASC 480, Distinguishing Liabilities from Equity (“ASC 480”). Otherwise, the offset to the contra-liability is recorded as a warrant liability in the condensed consolidated balance sheets and is subject to re-measurement to fair value at each balance sheet date, with any changes in fair value recognized in the condensed consolidated statements of operations and comprehensive loss. If the debt is retired early, the associated debt discount is then recognized immediately as interest expense in the condensed consolidated statements of operations and comprehensive loss.
Convertible Debt
In accordance with ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, when we issue notes with conversion features, we evaluate if the conversion feature is freestanding or embedded. If the conversion feature is embedded, we do not separate the conversion feature from the host contract for convertible notes that are not required to be accounted for as derivatives, or that do not result in substantial premiums accounted for as paid-in-capital. Consequently, we account for a convertible note as a single liability measured at its amortized cost as long as no other features require separation and recognition as derivatives. If the conversion feature is freestanding, or is embedded and meets the requirements to be separated, we account for the conversion feature as a derivative under ASC 815, Derivatives and Hedging (“ASC 815”). We record the derivative instrument at fair value at inception, and subsequently re-measure to fair value at each reporting period and immediately prior to the extinguishment of the derivative instrument, with any changes recorded in the condensed consolidated statements of operations and comprehensive loss.
Leases
At inception of a contract, we determine if a contract meets the definition of a lease. We determine if the contract conveys the right to control the use of an identified asset for a period of time. We assess throughout the period of use whether we have both of the following: (i) the right to obtain substantially all the economic benefits from use of the identified asset, and (ii) the right to direct the use of the identified asset. This determination is reassessed if the terms of the contract are changed. Leases are classified as operating or finance leases based on the terms of the lease agreement and certain characteristics of the identified asset. Right-of-use assets and lease liabilities are recognized at the lease commencement date based on the present value of the future lease payments less any lease incentives received. At the lease commencement date, the discount rate implicit in the lease is used to discount the lease liability if readily determinable. If not readily determinable or leases do not contain an implicit rate, our incremental borrowing rate is used as the discount rate. Our policy is to not record leases with an original term of twelve months or less within the condensed consolidated balance sheets and we recognize lease expense for these short-term leases on a straight-line basis over the lease term.
Certain lease agreements may require us to pay additional amounts for taxes, insurance, maintenance, and other expenses, which are generally referred to as non-lease components. Such variable non-lease components are treated as variable lease payments and recognized in the period in which the obligation for these payments is incurred. Variable lease components and variable non-lease components are not measured as part of the right-of-use asset and liability. Only when lease components and their associated non-lease components are fixed are they accounted for as a single lease component and are recognized as part of a right-of-use asset and liability. Total contract consideration is allocated to the fixed lease and non-lease component. This policy election applies consistently to all asset classes under lease agreements.
Leases may contain clauses for renewal at our option. Payments to be made in option periods are recognized as part of the right-of-use lease assets and lease liabilities when it is reasonably certain that the option to extend the lease will be exercised, or is not at our option. We determine whether the reasonably certain threshold is met by considering contract-, asset-, market-, and entity-based factors. Operating lease expense, which is recognized on a straight-line basis over the lease term, and the amortization of finance lease right-of-use assets, which are included in property and equipment and depreciated, are included in research and development or general and administrative expenses consistent with the leased assets’ primary use. Accretion on the liabilities for finance leases is included in interest expense.
Contingent Earn-Out Liabilities
We became a public company on December 30, 2020 via reverse recapitalization, pursuant to which we granted contingent earn-out awards (the “Contingent Earn-outs”) in the form of shares of our common stock, par value $
Common Stock Warrants
We account for common stock warrants as either equity- or liability-classified instruments based on an assessment of the warrant terms. The assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the warrants meet all the requirements for equity classification under ASC 815, including whether the warrants are indexed to our Common Stock, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance and, for liability-classified warrants, at each reporting period end date while the warrants are outstanding.
Grant Funding
We may submit applications to receive grant funding from governmental and non-governmental entities. We account for grants by analogizing to the grant accounting model under IAS 20, Accounting for Government Grants and Disclosure of Government Assistance (“IAS 20”). We recognize grant funding without conditions or continuing performance obligations, including certain research and development tax credits, as other income in the condensed consolidated statements of operations and comprehensive loss. We accrue certain research and development tax credits receivable in other current assets (see Note 4) in an amount equal to the qualifying expenses incurred in each period multiplied by the applicable reimbursement percentage and we recognize other income in the condensed consolidated statements of operations and comprehensive loss. After submission of our tax returns, we receive a cash refund of certain research and development tax credits and relieve the receivable.
We recognize grant funding with conditions or continuing performance obligations as a reduction in research and development or general and administrative expenses in the period during which the related qualifying expenses are incurred and as the conditions or performance obligations are fulfilled. Any amount received in advance of fulfilling such conditions or performance obligations is recorded in accrued liabilities (see Note 6) if the conditions or performance obligations are expected to be met within the next twelve months. We recognized grant funding as a reduction of research and development expenses totaling $
In October 2023 we were awarded a grant (“the NIH Grant”) in collaboration with New York University (“NYU”) as prime awardee (formerly Columbia University), and Synapticure, a neurology specialty health clinic, from the National Institutes of Health (“NIH”). The NIH Grant was awarded pursuant to the Accelerating Access to Critical Therapies for ALS Act to support up to a four-year Expanded Access Program (the “ACT-EAP”) for CNM-Au8® treatment of ALS. The NIH Grant totaled $
Foreign Currency Translation and Transactions
Our functional and reporting currency is the U.S. dollar (“USD”). Clene Australia and Clene Netherlands determined their functional currencies to be the Australian dollar and Euro, respectively. The results of our foreign currency operations are translated into USD at the average exchange rates during the period, assets and liabilities are translated using the exchange rate as of the balance sheet date, and stockholders’ deficit is translated using historical rates. Adjustments from the translation of the results of our foreign currency operations are excluded from net loss and are accumulated in a separate component of stockholders’ deficit. We also incur foreign exchange transaction gains and losses for purchases denominated in foreign currencies. Foreign exchange transaction gains and losses are included in other income (expense), net, as incurred.
Comprehensive Loss
Comprehensive loss includes net loss as well as other changes in stockholders’ deficit that result from transactions and economic events other than those with stockholders. The only elements of other comprehensive loss in any periods presented were the translation of foreign currency denominated balances of Clene Australia and Clene Netherlands to USD for consolidation.
Net Loss Per Share Attributable to Common Stockholders
Basic net loss per share attributable to common stockholders is calculated using our weighted-average outstanding common shares. Shares issuable for little or no cash consideration, such as pre-funded warrants, shall be considered outstanding common shares upon the satisfaction of any contingent conditions or when there are no contingent conditions. Diluted net loss per share attributable to common stockholders is calculated using our weighted-average outstanding common shares including the dilutive effect of securities as determined under the treasury stock method, except for the dilutive effect of convertible notes payable, which is calculated under the if-converted method, even if the embedded conversion option is out-of-the-money. In periods in which we report a net loss attributable to common stockholders, diluted net loss per share attributable to common stockholders is the same as basic net loss per share attributable to common stockholders, since dilutive common shares are not assumed to have been issued if their effect is anti-dilutive.
Segment Information
We report segment information based on ASC 280 Segment Reporting (“ASC 280”), which defines operating segments as components of a company that engage in activities from which it may recognize revenues and incur expenses, and for which operating results are regularly reviewed by the entity’s chief operating decision maker (“CODM”) to make decisions regarding resource allocation and assess performance, and for which discrete financial information is available. We determined that the Company is a single operating and reportable segment (“Products”) focused on treating central nervous system disorders through discovery, development, and commercialization of our novel CSN therapeutics. Our chief executive officer acts as the CODM and allocates resources and assesses performance at a consolidated level. Segment information is further described in Note 16.
Income Taxes
We account for income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the condensed consolidated financial statements or in our tax returns. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial statement basis 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 a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. We recognize deferred tax assets to the extent we believe these assets are more likely than not to be realized. In making such a determination, we consider all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and recent results of operations. If we determine that we would be able to realize any deferred tax assets in the future in excess of their net recorded amount, we would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes.
We record uncertain tax positions in accordance with ASC 740, Income Taxes, on the basis of a two-step process to (i) determine whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position, and (ii) for those tax positions that meet the more-likely-than-not recognition threshold, we recognize the largest amount of tax benefit that is more than 50% likely to be realized upon ultimate settlement with the related tax authority. We recognize interest and penalties related to unrecognized tax benefits within income tax expense in the condensed consolidated statements of operations and comprehensive loss. Any accrued interest and penalties related to uncertain tax positions will be reflected as liabilities in the condensed consolidated balance sheets.
Stock-Based Compensation
We account for stock-based compensation arrangements using a fair value-based method for costs related to all share-based payments. Stock-based compensation expense is recorded in research and development and general and administrative expenses based on the classification of the work performed by the grantees. The fair value is recognized over the period during which a grantee is required to provide services in exchange for the share-based payment, known as the requisite service period (usually the vesting period), on a straight-line basis. We generally grant stock options with a four-year requisite service period. We elect to account for forfeitures as they occur, rather than estimating expected forfeitures. We determine the fair value of stock option awards using a Black-Scholes option pricing model based on the closing price of our Common Stock on the date of grant.
Certain stock options may vest based upon performance conditions instead of service conditions, such as the achievement of regulatory milestones or financial performance measures. Compensation expense will be recognized when the conditions become probable of being satisfied. For the grant-date fair value, we estimate the expected term of stock options with performance conditions based upon the nature of the conditions. If the expected term is not estimable and the achievement of performance conditions is not probable, we use the contractual term as the expected term.

Note 9. Commitments and Contingencies
Commitments
We enter into agreements in the normal course of business with CROs for clinical trials and with vendors for preclinical studies and other services and products for operating purposes, which are cancelable at any time by us, subject to payment of our remaining obligations under binding purchase orders and, in certain cases, nominal early termination fees. These commitments are not deemed significant.
As of March 31, 2026 and December 31, 2025, we had commitments under various agreements for capital expenditures totaling $
Contingencies
From time to time, we may have certain contingent legal liabilities that arise in the ordinary course of business activities. We accrue a liability for such matters when it is probable that future expenditures will be made, and such expenditures can be reasonably estimated. We are not aware of any current material pending legal matters or claims.
We received two grants from the National Multiple Sclerosis Society (“NMSS”): (i) $
We account for the SSCPN Collateral Deficiency Fee and SSCPN Registration Fee (see Note 8) as contingent liabilities in accordance with ASC 450 that were not probable as of March 31, 2026, and therefore no contingent liabilities were recorded.

We are subject to taxation in the U.S., Australia, Netherlands, and various state jurisdictions. Our tax returns from 2016 to present are subject to examination by U.S. and state authorities due to the carry forward of unutilized net operating losses and research and development credits. We currently have no pending examinations. We compute our quarterly income tax provision by using a forecasted annual effective tax rate and adjust for any discrete items arising during the quarter. The primary difference between the effective tax rate and the federal statutory tax rate relates to the full valuation allowance on our net operating losses and other deferred tax assets.

Valuation of Notes Payable and Convertible Notes Payable
Our notes payable and convertible notes payable are categorized within Level 3 of the fair value hierarchy. The 2019 MD Loan and 2019 Cecil Loan are carried at the greater of principal plus accrued interest or the value of certain “phantom shares” (see Note 8) which approximates fair value. The 2022 MD Loan, 2022 DHCD Loan, and 2025 SSCP Notes are carried at amortized cost, which approximates fair value due to our credit risk and market interest rates.
The 2024 SSCP Notes are carried at their amortized cost of $
The SSCPN Derivative Liabilities met the requirements to be separated from the SSCP Notes as derivative instruments measured at fair value. We estimate the fair value of the SSCP Notes with and without the SSCPN Derivative Liabilities and calculate the difference as the implied fair value of the SSCPN Derivative Liabilities. The valuation model consists of a discounted cash flow model and a Black-Scholes option-pricing model with probability weights for the occurrence of (i) a change of control transaction, (ii) dissolution of the Company, or (iii) held to maturity. These estimates require significant judgment. The carrying amount may fluctuate significantly and the actual settlement amount may be materially different from the estimated fair value.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our condensed consolidated financial statements and related notes included elsewhere in this Quarterly Report. Unless the context otherwise requires, for purposes of this section, the terms the “Company,” “we,” “us,” or “our” are intended to mean the business and operations of Clene Inc. and its consolidated subsidiaries.
Business Overview
We are a clinical-stage pharmaceutical company pioneering the discovery, development, and commercialization of novel clean-surfaced nanotechnology (“CSN®”) therapeutics. CSN® therapeutics are comprised of atoms of transition elements that, when assembled in nanocrystal form, possess unusually high, unique catalytic activities not present in those same elements in bulk form. These catalytic activities drive, support, and maintain beneficial metabolic and energetic cellular reactions within diseased, stressed, and damaged cells.
Our patent-protected, proprietary position affords us the potential to develop a broad and deep pipeline of novel CSN therapeutics to address a range of diseases with high impact on human health. We innovated an electro-crystal-chemistry drug development platform that draws from advances in nanotechnology, plasma and quantum physics, materials science, and biochemistry. Our platform process results in nanocrystals with faceted structures and surfaces that are free of the chemical surface modifications that accompany other production methods. Many traditional methods of nanoparticle synthesis involve the unavoidable deposition of potentially toxic organic residues and stabilizing surfactants on the particle surfaces. Synthesizing stable nanocrystals that are both nontoxic and highly catalytic has overcome this significant hurdle in harnessing transition metal catalytic activity for therapeutic use. Our clean-surfaced nanocrystals exhibit catalytic activities many-fold higher than other commercially available nanoparticles, produced using various techniques, that we have comparatively evaluated.
Our development and clinical efforts are dedicated to revolutionizing the treatment of neurodegenerative diseases to restore and protect neuronal health and function. Our nanotherapeutics target cellular energy impairments that are common to many diseases and we are currently focused on addressing the high unmet medical needs in central nervous system disorders including amyotrophic lateral sclerosis (“ALS”), multiple sclerosis (“MS”), and Parkinson’s disease (“PD”). We currently have no drugs approved for commercial sale and have not generated any revenue from drug sales. We have never been profitable and have incurred operating losses in each year since inception. We generate revenue from sales of dietary supplements through our wholly-owned subsidiary, dOrbital, Inc., or through an exclusive license with 4Life Research LLC (“4Life”), an international supplier of health supplements, stockholder, debt holder, and related party. We anticipate this revenue to be small compared to our operating expenses and to the revenue we expect to generate from potential future sales of our drug candidates, for which we are currently conducting clinical trials.
Recent Developments of Our Clinical Programs
Amyotrophic Lateral Sclerosis
We had a Type C in-person meeting with the U.S. Food and Drug Administration (“FDA”) in the first quarter of 2026 to discuss the statistically significant reductions in neurofilament light (“NfL”) and glial fibrillary acidic protein (“GFAP”), the strong associations of biomarker improvements with longer survival in participants treated with CNM-Au8®, and to confirm our ability to file a new drug application (“NDA”) for ALS under an accelerated approval pathway. On May 4, 2026, we announced receipt of the final meeting minutes. During the meeting and confirmed in the final meeting minutes, the FDA stated that our “proposed data may be capable of supporting the submission and review of an [NDA] under the accelerated approval pathway for the treatment of ALS.” The FDA reminded the Company that the submission should demonstrate the effectiveness of an effect of CNM-Au8 on NfL and show that the magnitude of change in NfL is reasonably likely to predict clinical benefits in patients with ALS. We intend to submit our NDA in the third quarter of 2026, which will remain a matter of FDA review.
The FDA also noted that “NfL could potentially serve as a reasonably likely surrogate endpoint to support (an) accelerated approval.” This submission would occur under the Subpart H accelerated approval pathway (21 CFR 314.510) in ALS. The FDA has also requested that we provide additional information in our NDA, including to support a connection between the reported magnitude of reduction in NfL and clinical benefit, which we have prepared and will include in the submission.
The planned NDA submission will be supported by NfL biomarker and clinical data from the Phase 2 HEALEY ALS Platform Trial and its open-label extension, as well as the Phase 2 RESCUE-ALS Trial, and the National Institutes of Health-sponsored expanded access protocol for CNM-Au8. Supporting data include reductions in plasma NfL associated with longer survival in the open-label extension and additional clinical outcomes. CNM-Au8 has previously received Orphan Drug Designation from the FDA for the treatment of ALS. We plan to initiate our Phase 3 RESTORE-ALS trial during the first quarter of 2027 and serving as the post-approval confirmatory study.
Multiple Sclerosis
We met with the FDA in a Type B end of Phase 2 meeting during the third quarter of 2025 to review results from the Phase 2 VISIONARY-MS trial and discuss a planned Phase 3 study focusing on cognition improvement as an adjunct to standard-of-care MS therapies, addressing a critical unmet medical need for people struggling with MS. The FDA aligned with Clene acknowledging the limitations of the Expanded Disability Status Scale, a global measure of MS disease severity, and expressed openness to considering other potential primary endpoints, including cognition, to evaluate broader treatment effects. We plan to work closely with regulatory health authorities from the FDA, European Medicines Agency and other international regulatory bodies, MS experts, and patient representatives to determine the proper path to advance CNM-Au8 into Phase 3 and potential future approval. We also believe that once CNM-Au8 receives regulatory approval in another indication, licensing opportunities for the MS indication will improve.
The chart below reflects the growing body of evidence for CSN therapeutics from our completed and ongoing clinical programs.
Financial Overview
Our financial condition, results of operations, and the period-to-period comparability of our financial results are principally affected by the following factors:
Research and Development Expenses
The discovery and development of novel drug candidates requires a significant investment of resources over a prolonged period of time, and a core part of our strategy is to continue making sustained investments in this area. As a result of this commitment, our pipeline of drug candidates has been advancing, with substantially all our research and development expenses relating to our lead asset, CNM-Au8.
Our research and development expenses are affected by the scope and advancement of our existing product pipeline and the commencement of new drug programs. Drug candidates in later stages of clinical development generally have higher development costs than those in earlier stages, primarily due to costs and fees for per patient clinical trial sites for larger clinical trials, opening and monitoring clinical sites, contract research organization (“CRO”) activity, and manufacturing. We anticipate that our research and development expenses will increase in future years if and when we advance our assets into Phase 3. Additionally, if we are able to file an NDA with the FDA under an accelerated approval pathway or subsequent to future Phase 3 clinical development activities, if any, we anticipate that our research and development expenses related to regulatory activities would increase in advance of receiving regulatory approval.
Research and development costs consist primarily of payroll and personnel expenses for salaries, benefits, and stock-based compensation; supplies, materials, and manufacturing expenses to support our clinical trials; payments to CROs, principal investigators, and clinical trial sites; costs of preclinical and nonclinical activities; consulting costs; and allocated overhead costs, including rent, equipment, utilities, depreciation, insurance, maintenance, and information technology. Research and development costs are charged to operations as incurred, and nonrefundable advance payments related to future research and development activities are initially recorded as assets and are expensed when we receive the related goods or services. Grant funding is recognized as a reduction in research and development costs.
Our clinical trial accrual process seeks to account for expenses resulting from obligations under contracts with CROs, consultants, and clinical sites in connection with conducting clinical trials. The financial terms of these contracts vary and may result in payment flows that do not match the periods over which materials or services are provided to us under such contracts. We reflect the appropriate clinical trial expenses in the condensed consolidated financial statements by matching the appropriate expenses with the period in which services are performed. In the event advance payments are made to CROs, the payments are recorded as prepaid assets and expensed over the period in which services are performed.
General and Administrative Expenses
General and administrative expenses consist primarily of payroll and personnel expenses for salaries, benefits, and stock-based compensation; fees for legal, finance, accounting, tax, and information technology services; insurance costs; expenses for public and investor relations; rent, utilities, depreciation, and other costs related to our facilities.
We anticipate that our general and administrative expenses in future periods will be contingent upon our regulatory pathway with the FDA. If we are able to file an NDA with the FDA under an accelerated approval pathway, we anticipate our general and administrative expenses would increase in future periods to support increases in our drug development activities and as we build our commercial capabilities in advance of receiving regulatory approval. This potential increase will likely include increased headcount, increased stock-based compensation expenses, expanded infrastructure including certain sales and marketing activities performed ahead of regulatory approval, and increased insurance expenses. If we are unable to file an NDA with the FDA under an accelerated approval pathway, or if our NDA is not approved, we would need to continue investing in clinical research activities and we anticipate our general and administrative expenses would decrease in future periods as we decrease commercial manufacturing expansion projects, including at our Elkton, Maryland facility, and as we implement cost-saving initiatives, such as a reduction in compensation, a hiring freeze, and elimination of certain staff positions.
Total Other Income (Expense), Net
Total other income (expense), net, consists primarily of (i) interest income and interest expense, (ii) changes in the fair value of our common stock warrant liabilities and derivative liabilities, and (iii) research and development tax credits, unrestricted grants, and conditional grants for which applicable conditions have been met.

a decrease in expenses related to our lead drug candidate, CNM-Au8, primarily due to (A) a decrease in expenses related to our ALS clinical programs, including a decrease in expenses related to our two ongoing expanded access programs (“EAPs”) with Massachusetts General Hospital and our ongoing National Institutes of Health-sponsored compassionate-use EAP (the “ACT-EAP”) and a decrease in expenses for planning activities for our RESTORE-ALS clinical trial; (B) an increase in expenses related to our MS clinical programs primarily due to an increase in expenses for our MS EAP, (C) an increase in expenses for regulatory activities primarily driven by higher expenses related to our ongoing FDA discussions and NDA submission-related activities, and (D) a decrease in pre-clinical, non-clinical, and other general CNM-Au8-related expenses; |
| (ii) |
a decrease in unallocated expenses, primarily due to an offset to manufacturing expenses due to reprocessing multiple gold lots by our supplier when the commodity price of gold increased compared to the original purchase prices, partially offset by an increase in equipment-related expenses; |
| (iii) |
a decrease in personnel expenses, primarily due to cost-saving initiatives; |
| (iv) |
a decrease in stock-based compensation expense, primarily due to the timing of award grants, vesting, and forfeitures for research and development personnel; and |
| (v) |
a decrease in grant revenue, which is recorded as a reduction to research and development expense, due to a decrease in reimbursable research and development expenses in the ACT-EAP. |

| (v) |
a loss from the changes in fair value of common stock warrant liabilities during the three months ended March 31, 2026, and a gain during the three months ended March 31, 2025.

| (vi) | a gain from the change in fair value of the derivative liabilities separated from our senior secured convertible promissory notes during the three months ended March 31, 2026 and 2025. The changes in fair value were due to changes in price of our Common Stock and updates in valuation model assumptions (see “Critical Accounting Estimates”); |
| (vii) |
a decrease in research and development tax credits and unrestricted grants due to the receipt of Maryland tax credits during the three months ended March 31, 2025 that were not received during the three months ended March 31, 2026. |
Taxation
United States
We are incorporated in the state of Delaware and subject to statutory U.S. federal corporate income tax at a rate of 21.00%. We are also subject to state income tax in Maryland at a rate of 8.25%, and in Utah at a rate of 4.50%. As of March 31, 2026 and December 31, 2025, we recorded a full valuation allowance against our net deferred tax assets due to the uncertainty as to whether such assets will be realized resulting from our three-year cumulative loss position and the uncertainty surrounding our ability to generate pre-tax income in the foreseeable future.
Australia
Our wholly-owned subsidiary, Clene Australia Pty Ltd (“Clene Australia”), was established in Australia in March 2018 and is subject to corporate income tax at a rate of 30.00%. Clene Australia had no taxable income or provision for income taxes for the three months ended March 31, 2026 and 2025. We recorded other income of $36,000 and $24,000 for the three months ended March 31, 2026 and 2025, respectively, for research and development tax credits pertaining to Clene Australia for the 2026 and 2025 tax years, respectively.
Netherlands
Our wholly-owned subsidiary, Clene Netherlands B.V. (“Clene Netherlands”), was established in the Netherlands in April 2021 and is subject to corporate income tax at a rate of 19.00% up to €200,000 of taxable income and 25.80% for taxable income in excess of €200,000 for the three months ended March 31, 2026 and 2025. Clene Netherlands had no taxable income or provision for income taxes for the three months ended March 31, 2026 and 2025.
Liquidity and Capital Resources
Sources of Capital
We have incurred significant losses and negative cash flows from operations since our inception. We expect to incur additional losses in the future to fund our operations and conduct research and development of our drug candidates. We recognize the need to raise additional capital to fully implement our business plan. The long-term continuation of our business plan is dependent upon the generation of sufficient revenue from our products to offset expenses and capital expenditures. In the event that we do not generate sufficient revenue and are unable to obtain funding, we will be forced to delay, reduce, or eliminate some or all of our research and development programs, product portfolio expansion, commercialization efforts, or capital expenditures, which could adversely affect our business prospects, ability to meet long-term liquidity needs, or we may be unable to continue operations.
Since our inception, we have dedicated substantially all our resources to the development of our drug candidates. We have financed our operations principally through the following sources:
| ● | gross proceeds of $201.7 million from equity financing, including sales of common stock, preferred stock, common stock warrants, and pre-funded common stock warrants; |
| ● | gross proceeds of $71.1 million from borrowings under notes payable, convertible notes payable, and convertible promissory notes; |
| ● | gross proceeds of $9.4 million from our reverse recapitalization whereby we became a public company; |
| ● | gross proceeds of $10.2 million from refundable research and development tax credits; |
| ● | gross proceeds of $15.8 million from grants from various organizations; and |
| ● | gross proceeds of $1.1 million from stock option and warrant exercises. |
We also received indirect financial support for the HEALEY ALS Platform Trial, administered by Massachusetts General Hospital, which conducted an ALS platform trial of CNM-Au8 alongside multiple other drug candidates, at significantly lower costs than we would have otherwise incurred if we had conducted a comparably designed clinical trial at reasonable market rates.
Going Concern
We incurred a loss from operations of $2.1 million and $4.1 million for the three months ended March 31, 2026 and 2025, respectively. Our accumulated deficit was $316.4 million and $308.3 million as of March 31, 2026 and December 31, 2025, respectively. Our cash and cash equivalents totaled $5.9 million and $5.2 million as of March 31, 2026 and December 31, 2025, respectively, and net cash used in operating activities was $4.5 million and $5.0 million for the three months ended March 31, 2026 and 2025, respectively.
We have incurred significant losses and negative cash flows from operations since our inception. We have not generated significant revenue since our inception, and we do not anticipate generating significant revenue unless we successfully complete development and obtain regulatory approval for commercialization of a drug candidate. We expect to incur additional losses in the future, particularly as we advance the development of our clinical-stage drug candidates, continue research and development of our preclinical drug candidates, and initiate additional clinical trials of, and seek regulatory approval for, these and other future drug candidates. We expect that within the next twelve months, we will not have sufficient cash and other resources on hand to sustain our current operations or meet our obligations as they become due unless we obtain additional financing. Additionally, pursuant to our senior secured convertible promissory notes issued in December 2024 (the “2024 SSCP Notes”), we are required to maintain unrestricted cash and cash equivalents of at least $2.0 million to avoid acceleration of the full balance of the 2024 SSCP Notes (see Note 8 to the condensed consolidated financial statements). These conditions raise substantial doubt about the Company’s ability to continue as a going concern.
To mitigate our funding needs, we plan to raise additional funding, including exploring equity financing and offerings, debt financing, licensing or collaboration arrangements with third parties, as well as utilizing our existing at-the-market facility and potential proceeds from the exercise of outstanding warrants and stock options. These plans are subject to market conditions and reliance on third parties, and there is no assurance that effective implementation of our plans will result in the necessary funding to continue current operations. During the three months ended March 31, 2026, we raised $6.0 million of gross proceeds from a registered direct offering of equity securities (see Note 13 to the condensed consolidated financial statements), and subsequent to March 31, 2026, we raised $7.0 million of gross proceeds from a registered direct offering of equity securities (see Note 17 to the condensed consolidated financial statements). While we have implemented cost-saving initiatives, including delaying and reducing certain research and development programs and commercialization efforts, reducing employee compensation, and eliminating certain staff positions, we have concluded that our plans do not alleviate the substantial doubt about our ability to continue as a going concern beyond one year from the date the condensed consolidated financial statements are issued.
The accompanying condensed consolidated financial statements have been prepared assuming we will continue as a going concern, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. As a result, the accompanying condensed consolidated financial statements do not include any adjustments relating to the recoverability and classification of assets and their carrying amounts, or the amounts and classification of liabilities that may result should we be unable to continue as a going concern.
Short-Term Material Cash Requirements
For at least the next twelve months, our primary capital requirements are to fund our operations, including research and development, personnel, regulatory, and other clinical trial costs related to development of our lead drug candidate, CNM-Au8; general and administrative costs to support our drug development and pre-commercial activities in advance of receiving regulatory approval for our drug candidates; and principal and interest payments on our notes payable and convertible notes payable. Firm commitments for funds include approximately $1.1 million of payments under operating lease obligations, payment of principal and interest on notes payable and convertible notes payable totaling $2.5 million, and a commitment for capital expenditures totaling $0.2 million related to the construction of our manufacturing facilities. We expect to meet our short-term liquidity requirements primarily through cash on hand. Additional sources of funds include equity financing, debt financing, or other capital sources.
We enter into agreements in the normal course of business with CROs for clinical trials and with vendors for preclinical studies and other services and products for operating purposes, which are cancelable at any time by us, subject to payment of our remaining obligations under binding purchase orders and, in certain cases, nominal early termination fees. These commitments are not deemed significant.
Long-Term Material Cash Requirements
Beyond the next twelve months, our primary capital requirements are to fund our operations, including research and development, personnel, regulatory, and other clinical trial costs related to development of our lead drug candidate, CNM-Au8; general and administrative costs to support our drug development activities in advance of receiving regulatory approval for our drug candidates; and principal and interest payments on our notes payable and convertible notes payable. Additional funds may be spent to initiate new clinical trials, at our discretion. Known obligations beyond the next twelve months include $3.6 million of payments under operating lease obligations, and interest and principal repayment of notes payable and convertible notes payable of $18.6 million. We expect to meet our long-term liquidity requirements primarily through equity financing, debt financing, or other capital sources.

Operating Activities
Net cash used in operating activities was $4.5 million for the three months ended March 31, 2026, which resulted from a net loss of $8.1 million, adjusted for non-cash items totaling $7.8 million and a net change in operating assets and liabilities of $4.3 million. Significant non-cash items included: (i) depreciation expense of $0.4 million related to laboratory and office equipment and leasehold improvements, (ii) non-cash lease expense of $0.2 million, (iii) stock-based compensation expense of $1.3 million, (iv) accretion of debt discount of $0.3 million, (v) non-cash interest expense on notes payable of $0.4 million, (vi) issuance costs for common stock warrant liabilities of $0.4 million, (vii) a loss on initial issuance of equity from the fair value in excess of proceeds from a public equity offering of $4.6 million, (viii) a change in fair value of our common stock warrant liabilities of $1.1 million due to changes in the price of our Common Stock and changes in valuation model inputs, and (ix) a change in fair value of our derivative liabilities of $0.7 million due to changes in the price of our Common Stock and changes in valuation model inputs. The net change in operating assets and liabilities was primarily attributable to: (i) an increase in accounts payable of $0.4 million due to the timing of vendor invoicing and payments, (ii) an increase in prepaid expenses and other current assets of $3.3 million due to (A) the timing of vendor invoicing and payments, (B) an increase in metals to be used in research and development due to the timing of invoicing, payments, and deliveries from our supplier, and changes in the commodity price of gold during reprocessing by our supplier compared to the original purchase price, and (C) an increase in grants receivable related to ACT-EAP reimbursements, partially offset by (D) a decrease in research and development tax credits receivable due to the timing of refund payments, and (E) a decrease in miscellaneous prepaids and other current assets, (iii) a decrease in accrued liabilities of $1.2 million primarily due to (A) a decrease in accrued compensation and benefits resulting from payments of deferred employee bonuses in cash and equity and a decrease in deferred grants due to satisfaction of grant conditions or performance obligations, partially offset by (C) an increase in other miscellaneous accrued liabilities, and (iv) a decrease in operating lease obligations of $0.2 million.
Net cash used in operating activities was $5.0 million for the three months ended March 31, 2025, which resulted from a net loss of $0.8 million, adjusted for non-cash items totaling $0.9 million and a net change in operating assets and liabilities of $3.3 million. Significant non-cash items included: (i) depreciation expense of $0.4 million related to laboratory and office equipment and leasehold improvements, (ii) non-cash lease expense of $0.1 million, (iii) stock-based compensation expense of $1.9 million, (iv) accretion of debt discount of $0.2 million, (v) non-cash interest expense on notes payable of $12,000, (vi) a change in fair value of our common stock warrant liabilities of $2.5 million due to changes in the price of our Common Stock and changes in valuation model inputs, and (vii) a change in fair value of the our derivative liabilities of $1.1 million due to changes in the price of our Common Stock and changes in valuation model inputs. The net change in operating assets and liabilities was primarily attributable to: (i) a decrease in accounts receivable of $0.1 million and an increase in accounts payable of $0.2 million due to the timing of vendor invoicing and payments, (ii) a decrease in inventory of $30,000 (iii) an increase in prepaid expenses and other current assets of $0.9 million due to (A) the timing of vendor invoicing and payments, (B) the timing of receipt of metals to be used in research and development, (C) an increase in prepaid ACT-EAP expenses, and (D) an increase in research and development tax credits receivable, (iv) a decrease in accrued liabilities of $2.5 million primarily due to (A) a decrease in deferred grants, (B) a decrease in accrued CRO and clinical fees, and (C) a decrease in other miscellaneous accrued liabilities, partially offset by (D) an increase in accrued compensation and benefits, and (v) a decrease in operating lease obligations of $0.2 million.
Investing Activities
We had no net cash provided by or used in investing activities during the three months ended March 31, 2026 and 2025.
Financing Activities
Net cash provided by financing activities was $5.2 million for the three months ended March 31, 2026, which consisted of proceeds from the issuance of common stock and warrants, net of offering costs, of $5.3 million, partially offset by payments of notes payable of $0.1 million. Net cash provided by financing activities was $2.7 million for the three months ended March 31, 2025, which consisted of proceeds from the issuance of common stock of $2.7 million.
Public Offerings
In January 2026, pursuant to a placement agency agreement with BTIG, LLC (“BTIG”), we sold 928,333 shares of Common Stock, Series A Warrants to purchase up to 1,114,000 shares of Common Stock, and Series B Warrants to purchase up to 2,599,333 shares of Common Stock. The aggregate gross proceeds were approximately $6.0 million, of which $0.3 million was contributed by certain of our directors and their affiliated entities, excluding the proceeds, of any, from the exercise of the Series A Warrants and Series B Warrants and before deducting placement agent fees and expenses and other expenses payable by us. We paid BTIG a placement agent fee of 6.00% of the aggregate gross proceeds of the offering. The offering was made pursuant to our registration statement on Form S-3 (file number 333-286058), declared effective on April 25, 2025, and a related prospectus supplement. The total fair value of the Common Stock, Series A Warrants, and Series B Warrants sold in the offerings exceeded the offering proceeds by $4.6 million, therefore pursuant to ASC 815, we recognized this amount as a loss on the initial issuance of equity during the three months ended March 31, 2026. The placement agent fees and offering expenses were allocated to the Common Stock, Series A Warrants, and Series B Warrants sold in the offering based on their relative fair values, with the amounts allocated to the liability-classified Series A and Series B Warrants recorded as an expense and the amounts allocated to the Common Stock as a reduction to its initial carrying value.
Critical Accounting Estimates
Our discussion and analysis of our financial condition and results of operations is based on our condensed consolidated financial statements, which have been prepared in accordance with U.S. Generally Accepted Accounting Principles. The preparation of these condensed consolidated financial statements requires us to make estimates, assumptions, and judgments that affect the reported amounts of assets, liabilities, revenues, costs, and expenses. We evaluate our estimates and judgments on an ongoing basis, and our actual results may differ from these estimates. We base our estimates on historical experience, known trends and events, contractual milestones, and other various factors that are believed to be 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 consider the following estimates to be critical as they involve a significant level of estimation uncertainty and have had or are reasonably likely to have a material impact on our financial condition and results of operations.
Convertible Notes
In accordance with ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, we classified the 2022 DHCD Loan as convertible notes payable in the condensed consolidated balance sheets and did not separate the conversion option from the host contract as it did not meet the requirements for accounting as a derivative instrument. We account for the convertible note as a single liability measured at its amortized cost as of March 31, 2026 and December 31, 2025, with a carrying value of $5.3 million and $5.3 million, respectively.
We classified a portion of the senior secured convertible promissory notes (the “SSCP Notes”) as convertible notes payable in the consolidated balance sheets and separated three features from the host contract as derivative instruments measured at fair value: (i) the conversion option (the “SSCPN Conversion Feature”), (ii) the redemption option upon a change of control or any bankruptcy, liquidation, or other restructuring process consisting of a cash payment equal to 115% of the outstanding principal (the “SSCPN Redemption Feature”), and (iii) the acceleration option plus a penalty equal to 10% of all outstanding principal and accrued and unpaid interest upon the occurrence and continuation of certain events of default (the “SSCPN Default Feature,” collectively with the SSCPN Conversion Feature and SSCPN Redemption Feature, the “SSCPN Derivative Liabilities”). We accounted for the remainder of the SSCP Notes as liabilities measured at their amortized cost, with carrying values of (i) $9.9 million and $9.3 million for the 2024 SSCP Notes as of March 31, 2026 and December 31, 2025, respectively, and (ii) $1.5 million and $1.4 million for the 2025 SSCP Notes as of March 31, 2026 and December 31, 2025, respectively.
We remeasure the SSCPN Derivative Liabilities at each reporting date and record the change in fair value as a component of other income (expense), net in the condensed consolidated statements of operations and comprehensive loss. The change in fair value of the SSCPN Derivative Liabilities resulted in a gain of $0.7 million and a gain of $1.1 million during the three months ended March 31, 2026 and 2025, respectively. We estimate the fair value of the SSCP Notes with and without the SSCPN Derivative Liabilities and calculate the difference as the implied fair value of the SSCPN Derivative Liabilities. The valuation model consists of a discounted cash flow model and a Black-Scholes option-pricing model with probability weights for the occurrence of (i) a change of control transaction, (ii) dissolution of the Company, or (iii) held to maturity. These estimates require significant judgment. The unobservable valuation inputs were as follows:

Common Stock Warrant Liabilities
In accordance with ASC 815, we recognized the below common stock warrants as derivative liabilities measured at fair value and will remeasure them at each reporting date and record the change in fair value as a component of other income (expense), net, in the condensed consolidated statements of operations and comprehensive loss.
Pursuant to a loan with Avenue Venture Opportunities Fund, L.P. (“Avenue”), which we repaid in 2024, we issued a warrant to purchase 150,000 shares of Common Stock at $4.6014 per share (the “2023 Avenue Warrant”). The change in fair value of the 2023 Avenue Warrant resulted in a gain of $0.1 million and a gain of $0.2 million during the three months ended March 31, 2026 and 2025, respectively. We estimate the fair value using a Black-Scholes option-pricing model with probability weights for the occurrence of (i) settlement of the instrument upon a change of control transaction, (ii) dissolution of the Company, or (iii) held to expiration. These estimates require significant judgment. The unobservable valuation inputs were as follows:

Pursuant to an underwritten public offering in June 2023, we issued warrants to purchase 2,500,000 shares of Common Stock at $22.00 per share (the “Tranche A Warrants”). The change in fair value of the Tranche A Warrants resulted in a gain of $0.4 million and a gain of $0.6 million during the three months ended March 31, 2026 and 2025, respectively. We estimate the fair value using a Black-Scholes option-pricing model with probability weights for the occurrence of (i) acceptance of an NDA by the FDA for CNM-Au8, (ii) settlement upon a fundamental transaction, (iii) dissolution of the Company, and (iv) held to expiration.

Pursuant to a registered direct public offering in January 2026, we issued Series A Warrants to purchase 1,114,000 shares of Common Stock at $6.00 per share. The exercise price of the Series A Warrants will increase to $7.00 per share if (i) the Series A Warrant is exercised prior to our public announcement of the FDA’s posted action date under the Prescription Drug User Fee Act for our NDA for CNM-Au8 (the “Series A Trigger Announcement”), or (ii) the volume weighted average price (“VWAP”) of our Common Stock equals or exceeds $10.00 on the Series A Price Measurement Date, as defined below. The “Series A Price Measurement Date” means (A) the trading day on which the Series A Trigger Announcement is made, if such announcement is made prior to 9:00 a.m. (New York City time) on such trading day, or (B) the first trading day immediately following the day on which the Series A Trigger Announcement is made, if such announcement is made at or after 9:01 a.m. (New York City time) on a trading day or on a day that is not a trading day.
The change in fair value of the Series A Warrants resulted in a loss of $0.3 million during the three months ended March 31, 2026. We estimate the fair value using a Monte Carlo simulation with estimates for (i) the probability of the Series A Trigger Announcement (ii) the expected stock price increase if the Series A Trigger Announcement occurs, and (iii) the expected stock price decrease if the Series A Trigger Announcement does not occur. These estimates require significant judgment. The unobservable valuation inputs were as follows:

Pursuant to a registered direct public offering in January 2026, we issued Series B Warrants to purchase 2,599,333 shares of Common Stock at $6.00 per share. The exercise price of the Series B Warrants will increase to (i) $10.00 per share if the VWAP of our Common Stock equals or exceeds $20.00 on the Series B Price Measurement Date, or (ii) $12.50 per share if (A) the VWAP of our Common Stock equals or exceeds $25.00 on the Series B Price Measurement Date, or (B) the Series B Warrant is exercised prior to our public announcement of receipt of written approval from the FDA of our NDA for CNM-Au8 in ALS, which announcement shall be made promptly after receipt of such approval (the “Series B Trigger Announcement”). The “Series B Price Measurement Date” means (A) the trading day on which the Series B Trigger Announcement is made, if such announcement is made prior to 9:00 a.m. (New York City time) on such trading day, or (B) the first trading day immediately following the day on which the Series B Trigger Announcement is made, if such announcement is made at or after 9:01 a.m. (New York City time) on a trading day or on a day that is not a trading day.
The change in fair value of the Series B Warrants resulted in a loss of $1.9 million during the three months ended March 31, 2026. We estimate the fair value using a Monte Carlo simulation with estimates for (i) the probability of the Series B Announcement (ii) the expected stock price increase if the Series B Trigger Announcement occurs, and (iii) the expected stock price decrease if the Series B Trigger Announcement does not occur.

Income Taxes
We record uncertain tax positions in accordance with ASC 740, Income Taxes, on the basis of a two-step process to (i) determine whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position, and (ii) for those tax positions that meet the more-likely-than-not recognition threshold, we recognize the largest amount of tax benefit that is more than 50% likely to be realized upon ultimate settlement with the related tax authority. We recognize deferred tax assets to the extent we believe these assets are more likely than not to be realized. In making such a determination, we consider all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and recent results of operations. If we determine that we would be able to realize any deferred tax assets in the future in excess of their net recorded amount, we would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes. The estimation of these factors requires significant judgment. Based on our evaluation of these factors, we have not recorded income tax benefits for the net operating losses or for research and development tax credits or other deferred tax assets due to uncertainty of realizing benefits from these items.
Stock-Based Compensation
We account for stock-based compensation arrangements using a fair value-based method for costs related to all share-based payments including stock options and stock awards. The fair value is recognized over the period during which a grantee was required to provide services in exchange for the option award and service-based stock awards, known as the requisite service period (usually the vesting period), on a straight-line basis. For stock awards with market conditions, the fair value is recognized over the period based on the expected milestone achievement dates as the derived service period (usually the vesting period), on a straight-line basis. For stock awards with performance conditions, the grant-date fair value of these awards is the market price on the applicable grant date, and compensation expense will be recognized when the conditions become probable of being satisfied. We will recognize a cumulative true-up adjustment once the conditions become probable of being satisfied as the related service period had been completed in a prior period. We elect to account for forfeitures as they occur, rather than estimating expected forfeitures.
We estimate the fair value of stock options using a Black-Scholes option-pricing model, which requires significant judgment. The unobservable valuation inputs were as follows:

Item 3. Quantitative and Qualitative Disclosures About Market Risk
As a smaller reporting company, we are not required to provide information required by this Item.
Item 4. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
Under the supervision and with the participation of management, including our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of our disclosure controls and procedures as of March 31, 2026, as such term is defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934 (the “Exchange Act”). As a result of this evaluation, our principal executive officer and principal financial officer have concluded that, as of March 31, 2026, our disclosure controls and procedures were not effective due to the material weaknesses in internal control over financial reporting described below. Notwithstanding the identified material weaknesses, management, including our principal executive officer and principal financial officer, believes the condensed consolidated financial statements included in this Quarterly Report fairly represent, in all material respects, our financial condition, results of operations and cash flows as of and for the periods presented in accordance with U.S. Generally Accepted Accounting Principles.
Disclosure controls and procedures are designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.
Material Weaknesses in Internal Control over Financial Reporting
In connection with the audit of our financial statements as of and for the years ended December 31, 2025 and 2024, our management identified material weaknesses in our internal control over financial reporting. A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis. The material weaknesses identified relate to the fact that we did not design or maintain an effective control environment commensurate with our financial reporting requirements. This deficiency in our control environment contributed to the following additional material weaknesses related to control activities and information and communication within our internal control over financial reporting:
| ● | we did not design and maintain controls over the preparation and review of reconciliations and the review and segregation of duties over manual journal entries, including controls over the completeness and accuracy of information; and |
| ● | we did not design and maintain information technology (“IT”) general controls for IT systems that are relevant to the preparation of the financial statements. Specifically, we did not design and maintain: (a) user access controls to ensure appropriate segregation of duties and that adequately restrict user and privileged access to financial applications, programs, and data to our appropriate personnel; (b) program change management controls to ensure that IT program and data changes affecting financial IT applications and underlying accounting records are identified, tested, authorized, and implemented appropriately; (c) computer operations controls to ensure that data backups are authorized and monitored; and (d) testing and approval controls for program development to ensure that new software development is aligned with business and IT requirements. |
Each of the control deficiencies described above could result in a misstatement of one or more account balances or disclosures that would result in a material misstatement to the annual or interim consolidated financial statements that would not be prevented or detected. Accordingly, our management has determined that each of the control deficiencies described above constitute material weaknesses.
Material Weakness Remediation
Management continues to be actively engaged and committed to taking the steps necessary to remediate the control deficiencies that constituted the above material weaknesses. During 2025, we made the following enhancements to our control environment:
| ● | we strengthened the experience of our internal accounting team through refinement of our processes and internal controls over financial reporting and our IT and technical accounting resources; and |
| ● | until we have sufficient technical accounting resources, we engaged external consultants to provide support and to assist us in our evaluation of more complex applications of GAAP. |
Our remediation activities are continuing during 2026. In addition to the above actions, we expect to engage in additional activities, or have completed additional activities, including, but not limited to:
| ● | adding more technical accounting resources to enhance our control environment; and |
| ● | until we have sufficient technical accounting resources, engaging external consultants to provide support and to assist us in our evaluation of more complex applications of GAAP. |
We continue to enhance corporate oversight over process-level controls and structures to ensure that there is appropriate assignment of authority, responsibility, and accountability to enable remediation of our material weaknesses. We believe that our remediation plan will be sufficient to remediate the identified material weaknesses and strengthen our internal control over financial reporting. As we continue to evaluate, and work to improve, our internal control over financial reporting, management may determine that additional measures to address control deficiencies or modifications to the remediation plan are necessary.
Changes in Internal Control over Financial Reporting
Other than changes described under “—Material Weakness Remediation,” above there were no changes in our internal control over financial reporting during the quarter ended March 31, 2026, that have materially affected, or are 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 material pending legal proceedings. From time to time, we may, however, be involved in legal proceedings in the ordinary course of business. We cannot predict the outcome of any such legal proceedings, and despite the potential outcomes, the existence thereof may have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors.
Item 1A. Risk Factors
Our business, financial condition, and results of operations can be affected by a number of factors, whether currently known or unknown, including, but not limited to, those described in Part I, Item 1A, Risk Factors of our 2025 Annual Report on Form 10-K, which was filed with the SEC on March 17, 2026. There have been no material changes to the risk factors since previously disclosed in the 2025 Annual Report on Form 10-K. Any one or more of these factors could, directly or indirectly, cause our actual financial condition and results of operations to vary materially from past, or from anticipated future, financial condition and results of operations. Any of these factors, in whole or in part, could materially and adversely affect our business, financial condition, results of operations, and stock price.
