Rhea-AI Filing Summary

GRI Bio is a clinical-stage biopharmaceutical company advancing oral iNKT/dNKT modulators. The company reported a net loss of $2.89 million for the quarter and $5.94 million for the six months ended June 30, 2025, driven by higher research and development spending on GRI-0621 ($1.88 million in Q2; $3.52 million six months) and ongoing company overhead.

Cash and cash equivalents were $5.12 million at period end; management forecasts this funding will support operations into the fourth quarter of 2025 but discloses substantial doubt about going concern without additional financing. Clinical progress includes completion of Phase 2a enrollment in July 2025, an Independent Data Monitoring Committee review reporting no safety concerns for early cohorts, and topline biomarker results expected in Q3 2025. Recent financings include an April 2025 offering (net $4.02 million) and ATM sales (net $4.29 million through June 30, 2025). The company disclosed a material weakness in internal controls.

GRI Bio è un'azienda biofarmaceutica in fase clinica che sviluppa modulatori orali di iNKT/dNKT. L'azienda ha riportato una perdita netta di $2.89 million per il trimestre e di $5.94 million per i sei mesi chiusi al 30 giugno 2025, principalmente a causa dell'aumento delle spese di ricerca e sviluppo su GRI-0621 ($1.88 million nel Q2; $3.52 million nei sei mesi) e dei costi generali aziendali.

La liquidità e le disponibilità liquide ammontavano a $5.12 million a fine periodo; la direzione prevede che queste risorse sosterranno le attività fino al quarto trimestre del 2025, ma dichiara di avere seri dubbi sulla continuità aziendale senza finanziamenti aggiuntivi. I progressi clinici includono il completamento dell'arruolamento della Fase 2a a luglio 2025, la revisione da parte di un Comitato Indipendente per il Monitoraggio dei Dati che non ha rilevato problemi di sicurezza per le coorti iniziali, e risultati preliminari sui biomarcatori attesi nel Q3 2025. I finanziamenti recenti comprendono un'offerta di aprile 2025 (proventi netti $4.02 million) e vendite tramite ATM (proventi netti $4.29 million fino al 30 giugno 2025). L'azienda ha inoltre segnalato una criticità rilevante nei controlli interni.

La compañía registró una pérdida neta de $2.89 million para el trimestre y de $5.94 million para los seis meses cerrados al 30 de junio de 2025, impulsada por un aumento del gasto en I+D en GRI-0621 ($1.88 million en el Q2; $3.52 million en seis meses) y por los gastos generales continuos.

El efectivo y equivalentes de efectivo eran $5.12 million al cierre del periodo; la dirección pronostica que estos fondos sostendrán las operaciones hasta el cuarto trimestre de 2025, pero declara tener dudas sustanciales sobre la continuidad como empresa en funcionamiento sin financiamiento adicional. Los avances clínicos incluyen la finalización del reclutamiento de la Fase 2a en julio de 2025, la revisión de un Comité Independiente de Monitorización de Datos que no informó preocupaciones de seguridad para las cohortes iniciales, y resultados preliminares de biomarcadores esperados en el Q3 2025. Los financiamientos recientes incluyen una colocación en abril de 2025 (ingresos netos $4.02 million) y ventas mediante ATM (ingresos netos $4.29 million hasta el 30 de junio de 2025).

GRI Bio는 경구용 iNKT/dNKT 조절제(모듈레이터)를 개발 중인 임상 단계 바이오제약회사입니다. 회사는 분기 기준 $2.89 million의 순손실과 2025년 6월 30일로 종료된 6개월 동안 $5.94 million의 순손실을 보고했으며, 이는 GRI-0621에 대한 연구개발비 증가($1.88 million—Q2; $3.52 million—6개월)와 지속적인 일반관리 비용에 기인합니다.

기말 현금 및 현금성자산은 $5.12 million이었고, 경영진은 이 자금으로 2025년 4분기까지 운영을 지원할 수 있을 것으로 전망하지만 추가 자금 조달이 없을 경우 계속기업으로서의 존속에 대해 중대한 의문을 제기한다고 공시했습니다. 임상 진행 상황으로는 2025년 7월에 2a상 등록이 완료된 점, 독립 데이터 모니터링 위원회의 검토에서 초기 코호트에 대한 안전성 문제가 보고되지 않은 점, 그리고 Q3 2025에 발표될 것으로 예상되는 주요 바이오마커 결과가 포함됩니다. 최근 자금 조달로는 2025년 4월 공모(순수익 $4.02 million)와 ATM 매출(2025년 6월 30일까지 순수익 $4.29 million)이 있습니다. 회사는 또한 내부 통제에 중대한 결함이 있음을 공시했습니다.

La société a enregistré une perte nette de $2.89 million pour le trimestre et de $5.94 million pour les six mois clos au 30 juin 2025, en raison d'une augmentation des dépenses de R&D sur GRI-0621 ($1.88 million au T2 ; $3.52 million sur six mois) et des frais généraux continus.

Les liquidités et équivalents de trésorerie s'élevaient à $5.12 million à la fin de la période ; la direction prévoit que ces fonds soutiendront les opérations jusqu'au quatrième trimestre 2025, mais indique un doute substantiel quant à la capacité de poursuivre l'exploitation sans financement supplémentaire. Les avancées cliniques comprennent l'achèvement de l'inclusion de la phase 2a en juillet 2025, la revue d'un Comité Indépendant de Surveillance des Données n'ayant signalé aucune préoccupation de sécurité pour les cohortes initiales, et des résultats principaux de biomarqueurs attendus au T3 2025. Les financements récents incluent une émission en avril 2025 (produits nets $4.02 million) et des ventes via ATM (produits nets $4.29 million jusqu'au 30 juin 2025).

GRI Bio ist ein klinisch orientiertes Biopharmaunternehmen, das orale iNKT/dNKT-Modulatoren entwickelt. Das Unternehmen meldete einen Nettoverlust von $2.89 million für das Quartal und $5.94 million für die sechs Monate zum 30. Juni 2025, verursacht durch höhere Forschungs- und Entwicklungsausgaben für GRI-0621 ($1.88 million im Q2; $3.52 million in den sechs Monaten) sowie laufende Verwaltungskosten.

Barmittel und Zahlungsmitteläquivalente beliefen sich zum Periodenende auf $5.12 million; das Management prognostiziert, dass diese Mittel die Geschäftstätigkeit bis ins vierte Quartal 2025 unterstützen werden, räumt jedoch ohne zusätzliche Finanzierung erhebliche Zweifel an der Fortführungsfähigkeit ein. Klinische Fortschritte umfassen den Abschluss der Einschreibung für Phase 2a im Juli 2025, eine Überprüfung durch ein Unabhängiges Datenüberwachungskomitee, das für die frühen Kohorten keine Sicherheitsbedenken meldete, sowie erwartete Topline-Ergebnisse zu Biomarkern im Q3 2025. Zu den jüngsten Finanzierungsmaßnahmen zählen ein Angebot im April 2025 (Nettoerlös $4.02 million) und ATM-Verkäufe (Nettoerlös $4.29 million bis zum 30. Juni 2025). Das Unternehmen gab außerdem eine wesentliche Schwäche in den internen Kontrollen bekannt.

Positive
  • Phase 2a enrollment completed for GRI-0621 and topline biomarker results expected in Q3 2025
  • No early safety concerns reported by the Independent Data Monitoring Committee for initial cohorts
  • April 2025 offering raised net $4.02M, providing near-term liquidity
  • ATM sales generated net $4.29M through June 30, 2025 to support operations
Negative
  • Substantial doubt about going concern; cash of $5.12M projected to fund operations only into the fourth quarter of 2025 without additional financing
  • Six‑month net loss of $5.94M and accumulated deficit of $45.68M, reflecting continued cash consumption
  • Material weakness in internal controls related to accounting for a warrant repricing, which management is remediating
  • Significant potential dilution: common stock equivalents (options and warrants) totaled approximately 4.64 million as of June 30, 2025

Insights

TL;DR: Cash runway into Q4 2025 creates near-term financing risk despite recent $4M+ raises; losses and control weakness increase investor risk.

GRI reported $5.12M in cash and a six-month net loss of $5.94M, indicating limited runway absent additional financings. Management expects cash to fund operations into Q4 2025 but states there is substantial doubt regarding going concern. The April 2025 offering contributed net $4.02M and ATM sales generated net $4.29M through June 30, 2025, which materially improved liquidity in the period but will likely be insufficient to fund longer-term development without further raises. The identified material weakness in accounting controls is an added governance risk that may affect financial reporting until remediated.

TL;DR: Phase 2a enrollment completed with no early safety signals; topline biomarker readout in Q3 2025 is a meaningful clinical milestone.

GRI-0621 has been evaluated previously as oral tazarotene in over 1,700 patients historically and the company reports the Phase 2a biomarker study reached enrollment completion in July 2025. Independent Data Monitoring Committee reviews of the first cohorts reported no safety concerns. Management indicates biomarker changes consistent with an anti-fibrotic effect and expects topline results in Q3 2025. These clinical readouts are material to the development thesis but, as reported, do not yet change revenue or cash projections.

1.    ORGANIZATION AND DESCRIPTION OF BUSINESS
GRI Bio, Inc. (GRI or the Company), based in La Jolla, CA, was incorporated in Delaware in May 2009, which is the date of inception.
GRI is a clinical-stage biopharmaceutical company focused on discovering, developing, and commercializing innovative therapies that target serious diseases associated with dysregulated immune responses leading to inflammatory, fibrotic and autoimmune disorders. The Company’s goal is to be an industry leader in developing therapies to treat these diseases and to improve the lives of patients suffering from such diseases. The Company’s lead product candidate, GRI-0621, is an oral inhibitor of type 1 invariant Natural Killer T (iNKT) cells and is being developed for the treatment of severe fibrotic lung diseases such as idiopathic pulmonary fibrosis (IPF). The Company’s product candidate portfolio also includes GRI-0803 and a proprietary library of 500+ compounds. GRI-0803, the lead molecule selected from the library, is a novel oral agonist of type 2 diverse Natural Killer T (dNKT) cells and is being developed for the treatment of autoimmune disorders, with much of its preclinical work in Systemic Lupus Erythematosus Disease (SLE) or lupus and multiple sclerosis (MS).
Recapitalization
On January 29, 2024, the Company effected a reverse stock split of its common stock, par value $0.0001 per share (the Common Stock), at a ratio of one-for-seven (the January 2024 Reverse Stock Split). On June 17, 2024, the Company effected a reverse stock split of its Common Stock at a ratio of one-for-thirteen (the June 2024 Reverse Stock Split). On February 21, 2025, the Company effected a reverse stock split of its Common Stock at a ratio of one-for-seventeen (the February 2025 Reverse Stock Split and together with the January 2024 Reverse Stock Split and the June 2024 Reverse Stock Split, the Reverse Stock Splits). Unless otherwise noted, all references to share and per share amounts in these consolidated financial statements reflect the Reverse Stock Splits.
2.    LIQUIDITY
These unaudited interim consolidated financial statements have been prepared on the basis that the Company is a going concern, which contemplates, among other things, the realization of assets and the satisfaction of liabilities in the normal course of business. The Company has not generated any significant revenues from operations since inception and does not expect to do so in the foreseeable future. The Company has incurred operating losses since its inception in 2009 and as a result has incurred $45,678 in accumulated deficit through June 30, 2025. The Company has financed its working capital requirements to date through the issuance of equity and debt securities. As of June 30, 2025, the Company had cash of approximately $5,122.
On February 1, 2024, the Company entered into a securities purchase agreement (the February 2024 Purchase Agreement), pursuant to which the Company issued and sold Common Stock, pre-funded warrants and common warrants in a public offering (the February 2024 Offering) for net proceeds of $4,389, after deducting offering expenses of $1,110.
On May 20, 2024, the Company entered into an At The Market Offering Agreement (the Sales Agreement) with H.C. Wainwright & Co., LLC (Wainwright), pursuant to which the Company may sell and issue, subject to the limitations in the Sales Agreement, up to $10.0 million shares of Common Stock from time to time through Wainwright as its sales agent (the ATM Offering). Under the Sales Agreement, Wainwright is entitled to compensation of 3.0% of the gross offering proceeds of all shares of Common Stock sold through it pursuant to the Sales Agreement. As of June 30, 2025, the Company has sold 908,172 shares of Common Stock in the ATM Offering at a weighted-average price of $5.01 per share, for net proceeds of $4,292, after deducting commissions to the sales agent and other ATM Offering related expenses of $254.
On June 26, 2024, the Company entered into a securities purchase agreement (the June 2024 Purchase Agreement), pursuant to which the Company issued and sold Common Stock, pre-funded warrants and common warrants, in a public offering (the June 2024 Offering), for net proceeds of $3,172, after deducting offering expenses of $1,057.

Table of Contents
On October 21, 2024, the Company entered into letter agreements (the Repricing Letter Agreements) with certain holders (the Holders) of certain of its issued and outstanding common warrants to purchase shares of its Common Stock, pursuant to which these Holders exercised their common warrants for cash at a reduced exercise price. In addition, these Holders received new unregistered common warrants. The net proceeds to the Company from the exercise of the common warrants were $609, after deducting placement agent fees and offering expenses of $154.
On April 1, 2025, the Company entered into a securities purchase agreement (the April 2025 Purchase Agreement), pursuant to which the Company issued and sold Common Stock, pre-funded warrants and common warrants, in a public offering (the April 2025 Offering), for net proceeds of $4,020, after deducting offering expenses of $979.
Based on the Company’s current operating plan, the Company believes that its existing cash and cash equivalents will be sufficient to fund its operating expenses and capital expenditure requirements into the fourth quarter of 2025.
The Company’s ability to continue as a going concern is dependent on its ability to raise additional capital to fund its business activities, including its research and development program. The Company intends to raise capital through additional issuances of equity securities and/or short-term or long-term debt arrangements, but there can be no assurances any such financing will be available when needed, even if the Company’s research and development efforts are successful. If the Company is not able to obtain additional financing on acceptable terms and in the amounts necessary to fully fund its future operating requirements, it may be forced to reduce or discontinue its operations entirely. Therefore, there is substantial doubt about the Company’s ability to continue as a going concern for a period of one year from the issuance of these unaudited interim consolidated financial statements. These unaudited interim consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or amounts and classification of liabilities that might result from this uncertainty.
3.    BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
The accompanying unaudited interim consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (GAAP) for interim financial periods and pursuant to the rules of the U.S. Securities and Exchange Commission (the SEC). Any reference in the accompanying unaudited interim financial statements to “authoritative guidance” is meant to refer to GAAP as found in the Accounting Standards Codification (ASC) and Accounting Standards Updates (ASU) of the Financial Accounting Standards Board (FASB). The December 31, 2024 balance sheet was derived from the Company’s audited consolidated financial statements.
In the opinion of management, the unaudited interim consolidated financial statements furnished herein include all normal and recurring adjustments considered necessary to present fairly the Company’s financial position as of June 30, 2025, and the consolidated results of operations and consolidated stockholders’ equity for the three and six months ended June 30, 2025 and 2024 and consolidated cash flows for the six months ended June 30, 2025 and 2024. Consolidated results of operations for the three and six months ended June 30, 2025, are not necessarily indicative of the operating results that may be expected for the year ending December 31, 2025. The unaudited interim consolidated financial statements, presented herein, do not contain the required disclosures under GAAP for annual consolidated financial statements. The accompanying unaudited interim consolidated financial statements should be read in conjunction with the annual audited consolidated financial statements and related notes as of and for the year ended December 31, 2024, included in the Company’s Annual Report on Form 10-K filed with the SEC on March 14, 2025.
Principles of Consolidation
The unaudited interim consolidated financial statements include the accounts of GRI Bio, Inc. and its wholly owned subsidiary, GRI Bio Operations, Inc. All intercompany balances and transactions have been eliminated.
Use of Estimates
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period. Estimates and assumptions are primarily made in relation to the valuation of share options, warrant issuance and subsequent revaluations, valuation allowances relating to deferred tax assets, accrued expenses and estimation of the incremental borrowing rate for the operating lease. If actual results differ from the
8

Table of Contents
Company’s estimates, or to the extent these estimates are adjusted in future periods, the Company’s consolidated results of operations could either benefit from, or be adversely affected by, any such change in estimate.
Fair Value Measurements
Fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. To increase consistency and comparability in fair value measurements and related disclosures, ASC 820, Fair Value Measurement (ASC 820), establishes a fair value hierarchy which prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The three levels of fair value hierarchy defined by ASC 820 are described below:
Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.
Level 2: Quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability.
Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity).
As of June 30, 2025, the Company’s financial instruments included cash, cash equivalents, prepaid expenses and other current assets, accounts payable, accrued expenses and certain liability classified warrants. The carrying amounts reported in the consolidated balance sheets for cash, cash equivalents, prepaid expenses and other current assets, accounts payable and accrued expenses approximate their fair value based on the short-term maturity of these instruments. The Company recognizes transfers between levels of the fair value hierarchy on the date of the event or change in circumstances that caused the transfer. At June 30, 2025, there were no financial assets or liabilities measured at fair value on a recurring basis other than the liability classified warrants.
In May 2022, Vallon Pharmaceuticals, Inc. (Vallon) issued warrants (the May 2022 Warrants) in connection with a securities purchase agreement. Vallon evaluated the May 2022 Warrants in accordance with ASC 815-40, Derivatives and Hedging — Contracts in Entity’s Own Equity (ASC 815-40), and concluded that a provision in the May 2022 Warrants related to the reduction of the exercise price in certain circumstances precluded the May 2022 Warrants from being accounted for as components of equity. As a result, the May 2022 Warrants were recorded as a liability on the consolidated balance sheet. Vallon recorded the fair value of the May 2022 Warrants upon issuance using a Black-Scholes valuation model.
The Company is required to revalue the May 2022 Warrants at each reporting date with any changes in fair value recorded in its consolidated statements of operations. The valuation of the May 2022 Warrants is considered under Level 3 of the fair value hierarchy due to the need to use assumptions in the valuation that are both significant to the fair value measurement and unobservable. The change in the fair value of the Level 3 warrant liability is reflected in the consolidated statements of operations for the three and six months ended June 30, 2025. As of June 30, 2025 and December 31, 2024, the fair value of the warrant liability was immaterial.
Deferred Stock Issuance Costs
Deferred stock issuance costs represent incremental costs incurred that are directly attributable to proposed offerings of securities. The costs are charged against the gross proceeds of the respective offering upon closing.
Net Loss Per Common Share
Basic net loss per common share is computed by dividing net loss by the weighted-average number of shares of common stock outstanding during each period. For the six-month period ended June 30, 2024, basic net loss per common share includes the weighted average of the June 2024 Pre-Funded Warrants (as defined below). Diluted net loss per common share is computed by dividing the net loss by the weighted average number of shares of common stock outstanding during each period, plus the dilutive effect of common stock equivalents outstanding during each period, in accordance with ASC 260, Earnings Per Share. As the Company had a net loss in each of the three and six months ended June 30, 2025 and 2024, diluted net loss per common share is the same as basic net loss per common share for the period because the effects of potentially dilutive securities are antidilutive.

7. STOCK-BASED COMPENSATION
Amended and Restated 2018 Equity Incentive Plan
On April 21, 2023, the stockholders of the Company approved the Amended and Restated GRI Bio, Inc. 2018 Equity Incentive Plan (the A&R 2018 Plan). The A&R 2018 Plan provides the Company with the ability to grant stock options, restricted stock and other equity-based awards to employees, directors and consultants. Stock options granted by the Company under the A&R 2018 Plan generally have a contractual life of up to 10 years. As of June 30, 2025, awards granted under the A&R 2018 Plan representing the right to purchase or contingent right to receive up to an aggregate of 21,270 shares of the Company's Common Stock were outstanding and 21,275 shares of the Company’s Common Stock were reserved for issuance under the A&R 2018 Plan. The number of shares reserved for issuance under the A&R 2018 Plan may be increased pursuant to the A&R 2018 Plan’s “evergreen” provision on the first day of each calendar year beginning January 1, 2024 and ending on and including January 1, 2033, by a number of shares not to exceed 4% of the aggregate number of shares of the Company’s Common Stock outstanding on the final day of the immediately preceding calendar year.
The Company recorded stock-based compensation related to equity-based awards issued under the A&R 2018 Plan in the following expense categories of its accompanying consolidated statements of operations for the three and six months ended June 30, 2025 and 2024:

The Company measures equity-based awards granted to employees and non-employees based on their fair value on the date of the grant and recognizes compensation expense for those awards over the requisite service period or performance-based period, which is generally the vesting period of the respective award. The measurement date for service-based equity awards is the date of grant, and

equity-based compensation costs are recognized as expense over the requisite service period. The Company records expense for performance-based awards if the Company concludes that it is probable that the performance condition will be achieved.
The table below represents the activity of stock options granted to employees and non-employees for the six months ended June 30, 2025:

Vested and expected to vest at June 30, 202521,270$40.809.56
As of June 30, 2025, all of the outstanding and exercisable stock options were out of the money and therefore had no intrinsic value. As of June 30, 2025, the unrecognized compensation cost related to unvested stock options expected to vest was $174. This unrecognized compensation is expected to be recognized over a weighted-average amortization period of 0.78 years.
The Company granted 21,128 stock options to its employees and non-employee directors during the six months ended June 30, 2025. The Black-Scholes option-pricing model was used to estimate the grant date fair value of each stock option grant at the time of grant using the following weighted-average assumptions:

8. SEGMENT REPORTING
Operating segments are defined as components of an enterprise about which separate discrete information is available for evaluation by the chief operating decision maker (CODM), or decision-making group, in deciding how to allocate resources in assessing performance. The Company has one reportable segment: biotechnology research. The biotechnology research segment consists of the research and development of products for the treatment of inflammatory disease. The Company’s CODM is W. Marc Hertz, Ph.D., Chief Executive Officer and Director.
The accounting policies of the biotechnology research segment are the same as those described in the summary of significant accounting policies. The CODM assesses performance for the biotechnology research segment based on research and development expenses and general and administrative expenses as part of the overall review of the Company’s consolidated net loss and consolidated cash flows as compared to prior quarters and the Company’s operating budget.
The Company has incurred significant losses since its inception and anticipates incurring continued losses in the future. As such, the CODM uses cash forecast models in deciding how to allocate resources based on the Company’s available cash resources, as well as its forecasted expenditures. This information, in conjunction with the assessment of the probability of the success of the Company’s research and development activities, is used to plan the timing and size of future capital raises.

Employment Agreements
The Company has entered into employment contracts with its officers that provide for severance and continuation of benefits in the event of termination of employment by the Company without cause or by the employee for good reason. In addition, in the event of termination of employment following a change in control, the vesting of certain equity awards may be accelerated.
Separation and Release Agreement
In connection with the resignation of David Baker, the Company’s Former Chief Executive Officer, the Company and Mr. Baker entered into a Separation and Release Agreement on April 21, 2023 (the Separation Agreement). Pursuant to the terms of the Separation Agreement and his employment agreement, Mr. Baker received continuation of his then current salary and certain COBRA benefits for 18 months payable in accordance with the Company’s payroll practices. Mr. Baker also received a lump sum payment equal to 150% of his target bonus and agreed to reduce amounts payable with respect to certain future milestone payments.
10. SUBSEQUENT EVENTS
The One Big Beautiful Bill Act (“OBBBA”) was enacted on July 4, 2025. The Company is in the process of assessing the impact of this legislation on its financial statements. The OBBBA is not currently expected to materially impact the Company’s effective tax rate or cash flows in the current fiscal year.

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 financial statements and the related notes appearing elsewhere in this Quarterly Report on Form 10-Q (the Quarterly Report), the audited financial statements and notes thereto, as well as management’s discussion and analysis of financial condition and results of operations included in our Annual Report on Form 10-K for the year ended December 31, 2024 filed with the Securities and Exchange Commission (the SEC) on March 14, 2025 (the Annual Report). Some of the information contained in this discussion and analysis, including information with respect to our plans and strategy for our business and related financing, includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 12E of the Securities Exchange Act of 1934, as amended (the Exchange Act), that involve risks and uncertainties. As a result of many factors, including those factors set out under the section entitled “Risk Factors” included in the Annual Report, our actual results could differ materially from the results described in or implied by these forward-looking statements.
Overview
We are a clinical-stage biopharmaceutical company focused on discovering, developing, and commercializing innovative therapies that target serious diseases associated with dysregulated immune responses leading to inflammatory, fibrotic and autoimmune disorders. Our goal is to be an industry leader in developing therapies to treat these diseases and to improve the lives of patients suffering from such diseases.
Our lead product candidate, GRI-0621, is an oral inhibitor of type 1 invariant Natural Killer T (iNKT) cells. GRI-0621 is also an oral formulation of tazarotene, a synthetic retinoid acid receptor-beta and gamma selective agonist, that is approved in the United States for topical treatment of psoriasis and acne. As of June 30, 2025, it has been evaluated in over 1,700 patients as an oral product for up to 52-weeks. We are developing GRI-0621 for the treatment of severe fibrotic lung diseases such as idiopathic pulmonary fibrosis (IPF), a life-threatening progressive fibrotic disease of the lung that affects approximately 140,000 people in the United States, with up to 40,000 new cases per year in the United States. Some estimate that IPF affects 3 million globally. While there are currently two approved therapies for the treatment of lung fibrosis, neither has been associated with improvements in overall survival, and both therapies have been associated with significant side effects leading to poor therapeutic adherence. In preliminary data from our trials to date with GRI-0621, and earlier trials with oral tazarotene, we have observed GRI-0621 to be well-tolerated and to inhibit iNKT cell activity in subjects. We and others have shown that activated iNKT are upregulated in IPF, primary sclerosing cholangitis, metabolic dysfunction-associated steatohepatitis, alcoholic liver disease, systemic lupus erythematosus (SLE), multiple sclerosis (MS), ulcerative colitis patients as well as other indications. In these patients activated iNKT cells are correlated with more severe disease. The U.S. Food and Drug Administration has cleared our Investigative New Drug (IND) application, and we have received authorization of our clinical trial application from both the United Kingdom Medicines and Healthcare Products Regulatory Agency and the Australian Therapeutic Goods Administration to initiate the Phase 2a biomarker study evaluating GRI-0621 for the treatment of IPF in the, U.S., United Kingdom and Australia, respectively. We are evaluating GRI-0621 in a randomized, double-blind, multi-center Phase 2a biomarker study, for which we commenced enrollment in December 2023.Enrollment was completed in July 2025. No safety concerns have been observed by the Independent Data Monitoring Committee (IDMC) review of the first 12 subjects at two weeks and the first 24 subjects at six weeks of treatment. Changes from baseline of biomarkers in GRI-0621 treated subjects are suggestive of an anti-fibrotic effect, with decreases in biomarkers of fibrosis formation and increases in biomarkers of fibrosis resolution observed. Topline results from the Phase 2a biomarker study are expected in the third quarter of 2025.

Our product candidate portfolio also includes GRI-0803 and a proprietary library of 500+ compounds. GRI-0803, the lead molecule selected from the library, is a novel oral agonist of type 2 diverse Natural Killer T (dNKT) cells and would be developed for the treatment of autoimmune disorders, with much of our preclinical work in SLE or lupus and MS. In lupus, the immune system mistakenly attacks its own healthy tissues, especially joints and skin, but can affect almost every organ and tissue of the body. The condition can be fatal and often causes debilitating bouts of fatigue and pain that prevent nearly half of adult patients from working. Lupus affects between 160,000 - 200,000 patients in the United States, with around 80,000 – 100,000 patients in the United States suffering from kidney nephritis, one of the most serious manifestations of SLE, typically within five years of diagnosis. There is no cure for lupus, but medical interventions and lifestyle changes can help control it. SLE treatment consists primarily of immunosuppressive drugs that inhibit the activity of the immune system. Only two drugs have been approved for lupus in the past 50 years, and new treatment options are sorely needed. In order to focus our resources on our GRI-0621 program, we have limited our development of GRI-0803 pending additional funding. Subject to obtaining the requisite additional funding and IND clearance, we intend to evaluate GRI-0803 in a Phase 1a and 1b trial initially targeting SLE and to file an IND application with respect to this Phase

1a and 1b trial in 2026. We expect to continue to evaluate indications to select the best fit for further development of the program, but our initial focus would be on lupus.
Recent Developments
April 2025 Securities Purchase Agreement
On April 1, 2025, we entered into a securities purchase agreement (the April 2025 Purchase Agreement), pursuant to which we issued and sold, in a public offering (the April 2025 Offering), (i) 202,000 shares (the April 2025 Shares) of Common Stock, (ii) 1,186,888 pre-funded warrants (the April 2025 Pre-Funded Warrants) exercisable for an aggregate of 1,186,888 shares of Common Stock, (iii) 1,388,888 Series E-1 common stock warrants (the Series E-1 Common Warrants) to purchase up to 1,388,888 shares of Common Stock, (iv) 1,388,888 Series E-2 common stock warrants (the Series E-2 Common Warrants) to purchase up to 1,388,888 shares of Common Stock, and (v) 1,388,888 Series E-3 common stock warrants (the Series E-3 Common Warrants, and collectively with the Series E-1 Warrants and the Series E-2 Warrants, the Series E Common Warrants) to purchase up to 1,388,888 shares of Common Stock, for net proceeds of $4.0 million, before deducting offering expenses of $1.0 million. The securities were offered in combinations of (a) one April 2025 Share or one April 2025 Pre-Funded Warrant, together with (b) one Series E-1 Common Warrant, one Series E-2 Common Warrant and one Series E-3 Common Warrant, for a combined purchase price of $3.60 (less $0.0001 for each April 2025 Pre-Funded Warrant).
The April 2025 Pre-Funded Warrants were exercisable for one share of Common Stock at a price of $0.0001 per share, were exercisable immediately and expired when exercised in full. Each Series E Common Warrant is exercisable into one share of Common Stock at a price per share of $3.20 and is immediately exercisable. The Series E-1 Common Warrants will expire on the five-year anniversary of the date of issuance. The Series E-2 Common Warrants will expire on the 18-month anniversary of the date of issuance. The Series E-3 Common Warrants will expire on the nine-month anniversary of the date of issuance.
May 2024 At The Market Offering
On May 20, 2024, we entered into an At The Market Offering Agreement (the Sales Agreement) with H.C. Wainwright & Co., LLC (Wainwright), pursuant to which we may sell and issue, subject to the limitations in the Sales Agreement, shares up to $10.0 million of our Common Stock from time to time through Wainwright as our sales agent (the ATM Offering). On May 23, 2025, we filed a prospectus supplement to our registration statement on Form S-1 (File No. 333-279348) to increase the amount of shares of Common Stock that we may offer and sell under the Sales Agreement and applicable registration statement to an aggregate offering price of up to $1.8 million, which amount does not include the shares of Common Stock having an aggregate gross sales price of approximately $4.5 million that were sold under the ATM Offering through May 22, 2025, in accordance with the limitations set forth in Instruction I.B.6 of Form S-3. Under the Sales Agreement, Wainwright is entitled to compensation of 3.0% of the gross offering proceeds of all shares of Common Stock sold through it pursuant to the Sales Agreement.
As of June 30, 2025, we have sold 908,172 shares of our Common Stock in the ATM Offering at a weighted-average price of $5.01 per share, raising $4.5 million of gross proceeds and net proceeds of $4.3 million, after deducting commissions to the sales agent and other ATM Offering related expenses, of which 582,554 shares of Common Stock were sold during the quarter ended June 30, 2025, for gross proceeds of $941 and net proceeds of $825.
Financial Operations Overview
Research and Development Expenses
Research and development expenses include personnel costs associated with research and development activities, including third party contractors to perform research, conduct clinical trials and manufacture drug supplies and materials.
Our research and development expenses have consisted primarily of costs related to our development program for our lead product candidate GRI-0621. These expenses include:
employee-related expenses, such as salaries, bonuses and benefits, consultant-related expenses such as consultant fees and bonuses, stock-based compensation, overhead-related expenses and travel-related expenses for our research and development personnel; and
18

Table of Contents
expenses incurred under agreements with contract research organizations, contract manufacturing organizations and research laboratories in connection with our preclinical development, process development, manufacturing and clinical development activities as well as consultants that support the implementation of our clinical and non-clinical studies.
Although our direct research and development expenses are tracked by product candidate, we do not allocate employee costs and costs associated with our discovery efforts, laboratory supplies and facilities, including other indirect costs, to specific product candidates as these costs are deployed across multiple programs. We expect our research and development expenses to increase over the next several years as we conduct our planned clinical and preclinical activities for our product candidates.
General and Administrative Expenses
General and administrative expenses consist primarily of compensation and consulting related expenses for executives and other administrative personnel, professional fees and other corporate expenses, including legal and accounting fees, travel expenses, facilities-related expenses, and consulting services relating to corporate matters.
We expect our general and administrative expenses will continue to increase as we incur costs associated with being a public company, including expenses related to services associated with maintaining compliance with The Nasdaq Capital Market and SEC requirements, directors’ and officers’ insurance, legal and accounting costs and investor relations costs, as well as an increase in personnel expenses as we hire additional personnel.
Warrant Liability
In May 2022, Vallon Pharmaceuticals, Inc. (Vallon) issued warrants (the May 2022 Warrants) in connection with a securities purchase agreement. Vallon evaluated the May 2022 Warrants in accordance with Accounting Standards Codification (ASC) 815-40, Derivatives and Hedging — Contracts in Entity’s Own Equity (ASC 815-40), and concluded that a provision in the May 2022 Warrants related to the reduction of the exercise price in certain circumstances precludes the May 2022 Warrants from being accounted for as components of equity. As a result, the May 2022 Warrants were measured at fair value upon issuance using a Black-Scholes valuation model and are recorded as a liability on the consolidated balance sheet. The fair value of the May 2022 Warrants is measured at each reporting date and changes in fair value are recognized in the consolidated statements of operations in the period of change.
Interest Income
Interest income consists of interest earned on our cash and cash equivalents held with institutional banks.

Cash Flows from Operating Activities
For the six months ended June 30, 2025 and 2024, $4.9 million and $4.3 million were used in operating activities, respectively. The $0.6 million increase was primarily due to a $1.8 million increase in net loss and a $0.4 million decrease in cash used for prepaid and other assets and operating lease liabilities, offset by a $0.3 million increase in non-cash adjustments related to stock-based compensation expenses, as well as a $0.8 million increase in cash used for accounts payable and a $0.5 million increase in cash used for accrued expenses.
Cash Flows from Financing Activities
Net cash provided by financing activities was $5.0 million for the six months ended June 30, 2025 and was primarily related to $5.0 million in proceeds from the April 2025 Offering and $0.9 million in proceeds from the ATM Offering, offset by $0.9 million of stock issuance costs.
Net cash provided by financing activities was $8.9 million for the six months ended June 30, 2024 and was primarily related to $9.5 million of proceeds from the February 2024 Offering (defined below) and $1.0 million in proceeds from the ATM Offering. The increase was offset by $1.6 million of stock issuance costs.
April 2025 Securities Purchase Agreement
On April 1, 2025, we entered the April 2025 Purchase Agreement, pursuant to which we issued and sold, in the April 2025 Offering, (i) 202,000 April 2025 Shares, (ii) 1,186,888 April 2025 Pre-Funded Warrants exercisable for an aggregate of 1,186,888 shares of Common Stock, (iii) 1,388,888 Series E-1 Common Warrants to purchase up to 1,388,888 shares of Common Stock, (iv) 1,388,888 Series E-2 Common Warrants to purchase up to 1,388,888 shares of Common Stock, and (v) 1,388,888 Series E-3 Common Warrants, to purchase up to 1,388,888 shares of Common Stock, for net proceeds of $4.0 million, after deducting offering expenses of $1.0 million.
May 2024 At The Market Offering
As of June 30, 2025, we have sold 908,172 shares of our Common Stock in the ATM Offering at a weighted-average price of $5.01 per share, raising $4.5 million of gross proceeds and net proceeds of $4.3 million, after deducting commissions to the sales agent and other ATM Offering related expenses. On May 23, 2025, we filed a prospectus supplement to our registration statement on Form S-3 (File No. 333-279348) to increase the amount of shares of Common Stock that we may offer and sell under the Sales Agreement and applicable registration statement to an aggregate offering price of up to $1.8 million, which amount does not include the shares of Common Stock having an aggregate gross sales price of approximately $4.5 million that were sold under the ATM Offering through May 22, 2025, in accordance with the limitations set forth in Instruction I.B.6 of Form S-3.

February 2024 Securities Purchase Agreement
On February 1, 2024, we entered into securities purchase agreement , pursuant to which we issued and sold, in a public offering (the February 2024 Offering), (i) 1,495 shares of Common Stock, (ii) 21,131 pre-funded warrants exercisable for an aggregate of 21,131 shares of Common Stock, (iii) 22,631 Series B-1 common warrants exercisable for an aggregate of 22,631 shares of Common Stock, and (iv) 22,631 Series B-2 common warrants exercisable for an aggregate of 22,631 shares of Common Stock for net proceeds of $4.4 million, after deducting offering expenses of $1.1 million.
Future Funding Requirements
Our net losses were $5.9 million and $4.1 million for the six months ended June 30, 2025 and 2024, respectively. As of June 30, 2025, we had $5.1 million in cash and an accumulated deficit of $45.7 million. We expect to devote substantial financial resources to our planned activities, particularly as we prepare for, initiate, and conduct our planned clinical trials of GRI-0621 and GRI-0803, advance our discovery programs and continue our product development efforts. In addition, we expect to incur additional costs associated with operating as a public company.
Based on our current operating plan, we believe that our existing cash and cash equivalents will be sufficient to fund our operating expenses and capital expenditure requirements into the fourth quarter of 2025.
Accordingly, we will need to obtain substantial additional funding in connection with our continuing operations. We intend to raise capital through additional issuances of equity securities and/or short-term or long-term debt arrangements, but there can be no assurances any such financing will be available when needed, even if our research and development efforts are successful. If we are unable to secure adequate additional funding, we will need to reevaluate our operating plans and may be forced to make reductions in spending, extend payment terms with suppliers, liquidate assets where possible, delay, scale back or eliminate some or all of our development programs, or relinquish rights to our technology on less favorable terms than we would otherwise choose or cease operations entirely. These actions could materially impact our business, results of operations and future prospects and the value of shares of our Common Stock. In addition, attempting to secure additional financing may divert the time and attention of management from day-to-day activities and distract from our discovery and product development efforts. As a result, there is substantial doubt about our ability to continue as a going concern. We expect to continue to incur significant and increasing operating losses at least for the foreseeable future. We do not expect to generate product revenue unless and until we successfully complete development, obtain regulatory approval for and successfully commercialize our current, or any future, product candidates.
Off-Balance Sheet Arrangements
We are not party to any off-balance sheet transactions. We have no guarantees or obligations other than those which arise out of normal business operations.
Critical Accounting Policies and Estimates
Our management’s discussion and analysis of its financial condition and results of operations is based on its unaudited interim consolidated financial statements, which have been prepared in accordance with generally accepted accounting principles in the United States (GAAP). The preparation of these unaudited interim consolidated financial statements requires us to make estimates and assumptions that affect the amounts reported in the unaudited interim consolidated financial statements and accompanying notes. Management evaluates these estimates and judgments on an ongoing basis. Management bases its estimates on historical experience and on various other factors that it believes are reasonable under the circumstances. Actual results could differ from those estimates.
Our significant accounting policies are described in more detail in Note 3, “Summary of Significant Accounting Policies”, in our Annual Report.
Emerging Growth Company Status
We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012 (the JOBS Act) and may remain an emerging growth company for up to five years. For so long as we remain an emerging growth company, we are permitted and intend to rely on exemptions from certain disclosure requirements that are applicable to other public companies that are not applicable to emerging growth companies. These exemptions include:
22

Table of Contents
reduced disclosure about our executive compensation arrangements;
no non-binding stockholder advisory votes on executive compensation or golden parachute arrangements; and
exemption from the auditor attestation requirement in the assessment of our internal control over financial reporting.
We have taken advantage of reduced reporting requirements in this report and may continue to do so until such time that we are no longer an emerging growth company. We will remain an “emerging growth company” until the earliest of (a) the last day of the fiscal year in which we have total annual gross revenues of $1.235 billion or more, (b) December 31, 2026, the last day of the fiscal year following the fifth anniversary of the completion of Vallon’s initial public offering, (c) the date on which we have issued more than $1.0 billion in nonconvertible debt during the previous three years or (d) the date on which we are deemed to be a large accelerated filer under the rules of the SEC. Section 107 of the JOBS Act provides that an emerging growth company can take advantage of the extended transition period for complying with new or revised accounting standards.
Item 3. Quantitative and Qualitative Disclosures About Market Risk.
Not applicable to a smaller reporting company.
Item 4. Controls and Procedures.
Management’s Evaluation of our Disclosure Controls and Procedures
Our Chief Executive Officer and Chief Financial Officer evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) or 15d-15(e)) of the Exchange Act as of June 30, 2025. We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in its periodic and current reports that we file with the SEC 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. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable and not absolute assurance of achieving the desired control objectives. In reaching a reasonable level of assurance, management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. In addition, the design of any system of controls is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.
Based upon their evaluation, the Chief Executive Officer and the Chief Financial Officer concluded that our disclosure controls and procedures were not effective as of June 30, 2025 due to the material weakness described in our Annual Report.
In the course of preparing the Company’s financial statements for the Annual Report, management identified a material weakness related to the inaccurate computation of the non-cash deemed dividend associated with the re-pricing of the Series B Common Warrants in the Warrant Repricing Transaction in accordance with applicable GAAP guidance.
Management has implemented a plan to remediate this material weakness which includes the continued engagement of third-party professionals with appropriate expertise in accounting and reporting under GAAP and SEC regulations who have adequate experience related to non-recurring debt and equity transactions and the enhanced documentation related to the accounting treatment for such transactions and who will assist in reviewing the attendant calculations. Management has also refined our processes for communicating with our auditor as to when our financial statements and related materials have passed through the Company’s internal control processes.
Notwithstanding this material weakness, we believe that our financial statements contained in this Quarterly Report on Form 10-Q fairly present our financial position, results of operations and cash flows for the periods covered by this report in all material respects.

Changes in Internal Control over Financial Reporting
As noted above, we have implemented certain measures to remediate the material weakness identified in the design and operation of our internal controls over financial reporting. There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) other than those noted above that occurred during the fiscal quarter covered by this report that have materially affected or are reasonably likely to materially affect our internal control over financial reporting.
Limitations of Effectiveness of Control
It should be noted that any system of controls, however well designed and operated, can provide only reasonable, and not absolute, assurance that the objectives of the system are met. The design of any control system is based, in part, upon the benefits of the control system relative to its costs. Control systems can be circumvented by the individual acts of some persons, by collusion of two or more people or by management override of the controls. In addition, over time, controls may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of these and other inherent limitations of control systems, there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions, regardless of how remote.
