CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS
This prospectus and any applicable prospectus supplement or free writing prospectus, including the documents that we incorporate by reference herein and therein, contain “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). These statements relate to future events or to our future operating or financial performance and involve known and unknown risks, uncertainties and other factors which may cause our actual results, performance or achievements to be materially different from any future results, performances or achievements expressed or implied by the forward-looking statements.
In some cases, you can identify forward-looking statements by terms such as “may,” “will,” “should,” “could,” “would,” “expects,” “plans,” “anticipates,” “believes,” “estimates,” “projects,” “predicts,” “potential” and similar expressions intended to identify forward-looking statements. These statements reflect our current views with respect to future events and are based on assumptions and are subject to risks and uncertainties. As such, our actual results may differ significantly from those expressed in any forward-looking statements. Given these uncertainties, you should not place undue reliance on these forward-looking statements. All statements other than statements of historical fact are statements that could be deemed forward-looking statements. For example, forward-looking statements include, but are not limited to statements about:
our history of losses and needs for additional capital to fund our operations and our inability to obtain additional capital on acceptable terms, or at all;
our ability to comply with the applicable continued listing requirements of Nasdaq;
our limited operating history and the difficulties encountered by a small developing company;
expected restructuring-related cash outlays, including the timing and amount of those outlays;
the timing of initiation of planned clinical trials;
the timing of any planned Investigational New Drug Application (“IND”) or new drug application;
plans to research, develop, and commercialize current and future product candidates;
the ability to enter into new collaborations, and to fulfill obligations under any such collaboration agreements;
the clinical utility, potential benefits, and market acceptance of product candidates;
commercialization, marketing, and manufacturing capabilities and strategy;
the ability to identify additional products or product candidates with significant commercial potential;
developments and projections relating to the Company’s competitors and their industries;
the impact of government laws and regulations;
the Company’s ability to protect its intellectual property position;
estimates regarding future revenue, expenses, capital requirements, and need for additional financing following the proposed transactions; and
statements of belief and any statement of assumptions underlying any of the foregoing.
We discuss many of these risks in the “Risk Factors” section incorporated by reference from our most recent Annual Report on Form 10-K and any subsequent Quarterly Reports on Form 10-Q or Current Reports on Form 8-K, as well as any amendments thereto reflected in subsequent filings with the SEC.
iii


Also, these forward-looking statements represent our estimates and assumptions only as of the date of the document containing the applicable statement. Unless required by law, we undertake no obligation to update or revise any forward-looking statements to reflect new information or future events or developments. Thus, you should not assume that our silence over time means that actual events are bearing out as expressed or implied in such forward-looking statements. You should read this prospectus, any applicable prospectus supplement, together with the documents that we have filed with the Commission that are incorporated by reference and any free writing prospectus we have authorized for use in connection with this offering, completely and with the understanding that our actual future results may be materially different from what we expect. We qualify all of the forward-looking statements in the foregoing documents by these cautionary statements.

PROSPECTUS SUMMARY
This summary highlights certain information about us, this offering and selected information contained elsewhere in or incorporated by reference into this prospectus. This summary is not complete and does not contain all of the information that you should consider before making an investment decision. For a more complete understanding of our company, you should read and consider carefully the more detailed information included or incorporated by reference in this prospectus and any applicable prospectus supplement, including the information incorporated by reference from our most recent Annual Report on Form 10-K and any subsequent Quarterly Reports on Form 10-Q or Current Reports on Form 8-K, before making an investment decision.
Company Overview
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. 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.
GRI’s lead product candidate, GRI-0621, is an oral inhibitor of type 1 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 March 31, 2023, it has been evaluated in over 1,700 patients as an oral product for up to 52-weeks. GRI is 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 and 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 GRI’s trials to date with GRI-0621, and earlier trials with oral tazarotene, GRI has observed GRI-0621 to be well-tolerated and to inhibit iNKT cell activity in subjects. GRI and others have shown that activated iNKT are upregulated in IPF, primary sclerosing cholangitis, non-alcoholic steatohepatitis, alcoholic liver disease, Systemic Lupus Erythematosus Disease (“SLE”), multiple sclerosis (“MS”), ulcerative colitis patients as well as other indications. In these patients activated iNKT cells are correlated with more severe disease. GRI is initiating a Phase 2a trial in 36 IPF patients in the second half of 2023 and expects topline results from this trial to be available in the second half of 2024.
GRI’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 Natural Killer T (“type 2 NKT”) cells. GRI is developing GRI-0803 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. Subject to IND clearance, GRI intends to evaluate GRI-0803 in a Phase 1a and 1b trial initially targeting SLE. GRI expects to file an IND with respect to this Phase 1a and 1b trial in the first half of 2024. GRI will continue to evaluate indications to select the best fit for further development of the program, but GRI’s initial focus is on lupus.
Merger Transaction
On April 21, 2023, pursuant to the Agreement and Plan of Merger, dated as of December 13, 2022, as amended on February 17, 2023 (the “Merger Agreement”), by and among the Company, GRI Bio Operations, Inc., formerly known as GRI Bio, Inc. (“Private GRI”), and Vallon Merger Sub, Inc., a Delaware corporation and wholly owned subsidiary of the Company (“Merger Sub”), Merger Sub was merged with and into Private GRI (the “Merger”), with
1


Private GRI surviving the Merger as a wholly owned subsidiary of the Company. In connection with the Merger, and immediately prior to the effective time of the Merger (the “Effective Time”), the Company effected a reverse stock split of the Common Stock at a ratio of 1-for-30 (the “Reverse Split”). Unless otherwise noted, all references to share and per share amounts in this prospectus reflect the Reverse Split. Also, in connection with the closing of the Merger (the “Closing”), the Company changed its name from “Vallon Pharmaceuticals, Inc.” to “GRI Bio, Inc.”
At the Effective Time:
(a)Each share of Private GRI’s common stock (“Private GRI Common Stock”) outstanding immediately prior to the Effective Time, including any shares of Private GRI Common Stock issued pursuant to the Equity Financing (as defined below) automatically converted solely into the right to receive a number of shares of the Common Stock equal to 0.0374 (the “Exchange Ratio”).
(b)Each option to purchase shares of Private GRI Common Stock (each, a “Private GRI Option”) outstanding and unexercised immediately prior to the Effective Time under the GRI Bio, Inc. 2015 Equity Incentive Plan (the “Private GRI Plan”), whether or not vested, converted into and became an option to purchase shares of Common Stock, and the Company assumed the Private GRI Plan and each such Private GRI Option in accordance with the terms of the Private GRI Plan (the “Assumed Options”). The number of shares of Common Stock subject to each Assumed Option was determined by multiplying (i) the number of shares of Private GRI Common Stock that were subject to such Private GRI Option, as in effect immediately prior to the Effective Time, by (ii) the Exchange Ratio, and rounding the resulting number down to the nearest whole number of shares of Common Stock. The per share exercise price for the Common Stock issuable upon exercise of each Assumed Option was determined by dividing (A) the per share exercise price of such Assumed Option, as in effect immediately prior to the Effective Time, by (B) the Exchange Ratio and rounding the resulting per share exercise price up to the nearest whole cent. Any restriction on the exercise of any Assumed Option continued in full force and effect and the term, exercisability, vesting schedule, and any other provisions of such Assumed Option otherwise remained unchanged.
(c)Each warrant to purchase shares of Private GRI Common Stock (the “Private GRI Warrants”) outstanding immediately prior to the Effective Time was assumed by the Company and converted into a warrant to purchase Common Stock (the “Assumed Warrants”) and thereafter (i) each Assumed Warrant became exercisable solely for shares of Common Stock; (ii) the number of shares of Common Stock subject to each Assumed Warrant was determined by multiplying (A) the number of shares of Private GRI Common Stock that were subject to such Private GRI Warrant, as in effect immediately prior to the Effective Time, by (B) the Exchange Ratio, and rounding the resulting number down to the nearest whole number of shares of Common Stock; (iii) the per share exercise price for the Common Stock issuable upon exercise of each Assumed Warrant was determined by dividing (A) the exercise price per share of the Private GRI Common Stock subject to such Private GRI Warrant, as in effect immediately prior to the Effective Time, by (B) the Exchange Ratio, and rounding the resulting exercise price up to the nearest whole cent.
(d)The Bridge Warrants were exchanged for warrants (the “Exchange Warrants”) to purchase an aggregate of 421,590 shares of Company Common Stock. The Exchange Warrants contain substantively similar terms to the Bridge Warrants, and have an initial exercise price equal to $14.73 per share.
(e)All rights with respect to Private GRI restricted stock awards were assumed by the Company and converted into Company restricted stock awards with the number of shares subject to each restricted stock award multiplied by the Exchange Ratio and rounding the resulting number down to the nearest whole number of shares of Common Stock. The term, exercisability, vesting schedule and other provisions of the Private GRI restricted stock awards otherwise remained unchanged.

Equity Financing
Securities Purchase Agreement (Bridge Financing)
In connection with signing the Merger Agreement, Private GRI entered into a Securities Purchase Agreement, dated as of December 13, 2022 (the “Bridge SPA”) with the selling stockholder (the “Investor”), pursuant to which, among other things, the Investor purchased, and Private GRI issued, senior secured notes in the aggregate principal amount of up to approximately $3.3 million, in exchange for an aggregate purchase price of up to approximately $2.5 million. In addition, Private GRI issued the Investor warrants to purchase an aggregate of 2,504,980 shares of Private GRI Common Stock (the “Bridge Warrants”). As a result of the Merger, at the Effective Time, the Bridge Warrants were exchanged for the Exchange Warrants. The Exchange Warrants contain substantively similar terms to the Bridge Warrants, and have an initial exercise price equal to $14.73 per share. The exercise price of the Exchange Warrants is subject to adjustment for splits and similar recapitalization events.
Securities Purchase Agreement (Equity Financing)
In addition to the Bridge SPA, in connection with signing the Merger Agreement, the Company, Private GRI and the Investor entered into a Securities Purchase Agreement, dated as of December 13, 2022 (the “Equity SPA”). Pursuant to the Equity SPA, immediately prior to the Closing, Private GRI issued 6,787,219 shares of Private GRI Common Stock (the “Initial Shares”) to the Investor and 27,148,877 shares of Private GRI Common Stock (the “Additional Shares”) into escrow with an escrow agent. At the Closing, pursuant to the Merger, the Initial Shares converted into an aggregate of 253,842 shares of Common Stock and the Additional Shares converted into an aggregate of 1,015,368 shares of Common Stock. On May 8,2023, in accordance with the terms of the Equity SPA, the Company and the Investor authorized the escrow agent to, subject to beneficial ownership limitations, disburse to the Investor all of the shares of Company Common Stock issued in exchange for the Additional Shares (the “Escrow Shares”).
Pursuant to the Equity SPA, the Company issued to the Investor on May 8, 2023 (i) Series A-1 Warrants to purchase 1,269,210 shares of Common Stock with an initial exercise price of $13.51 per share, (ii) Series A-2 Warrants to purchase 1,142,289 shares of Common Stock with an initial exercise price of $14.74 per share, and (iii) Series T Warrants to purchase (x) 814,467 shares of Common Stock at an exercise price of $12.28 per share and (y) if the Series T Warrants are exercised in full by paying the Aggregate Exercise Price in cash, an additional amount of Series A-1 Warrants and Series A-2 Warrants, each to purchase 814,467 shares of Common Stock at their respective exercise price (collectively, the “Equity Warrants”). The Company may force the exercise of Series T Warrants subject to the satisfaction of certain equity conditions.

Implications of Being a Smaller Reporting Company
We are a “smaller reporting company” as defined in Item 10(f)(1) of Regulation S-K. Smaller reporting companies may take advantage of certain reduced disclosure obligations, including, among other things, providing only two years of audited financial statements. We will remain a smaller reporting company until the last day of any fiscal year for so long as either (1) the market value of our shares of Common Stock held by non-affiliates does not equal or exceed $250.0 million as of the prior June 30th, or (2) our annual revenues did not equal or exceed $100.0 million during such completed fiscal year and the market value of our shares of Common Stock held by non-affiliates did not equal or exceed $700.0 million as of the prior June 30th. To the extent we take advantage of any reduced disclosure obligations, it may make comparison of our financial statements with other public companies difficult or impossible.

RISK FACTORS
Investing in our securities involves risks. Before you make a decision to buy our securities, in addition to the risks and uncertainties discussed above under “Cautionary Note Regarding Forward-Looking Statements,” you should carefully consider the specific risks incorporated by reference in this prospectus to our most recent Annual Report on Form 10-K and any subsequent Quarterly Reports on Form 10-Q or Current Reports on Form 8-K, and all other information contained or incorporated by reference into this prospectus, as updated by our subsequent filings under the Exchange Act, and the risk factors and other information contained in any applicable prospectus supplement and any applicable free writing prospectus before acquiring any such securities.

SELLING STOCKHOLDERS
The shares of Common Stock being offered by the selling stockholders are those issuable to the selling stockholders, upon exercise of the Warrants. For additional information regarding the issuances of those shares of Common Stock and the Warrants, see “Prospectus Summary—Equity Financing” above. We are registering the shares of Common Stock in order to permit the selling stockholders to offer the shares for resale from time to time. Except for the ownership of the shares of Common Stock and the Warrants, the selling stockholders have not had any material relationship with us within the past three years. The selling stockholders may sell all, some or none of their shares in this offering. See “Plan of Distribution.”
The table below lists the selling stockholders and other information regarding the beneficial ownership (as determined under Section 13(d) of the Exchange Act and the rules and regulations thereunder) of the shares of Common Stock by each of the selling stockholders. Under the terms of the Equity Warrants and Exchange Warrants, a selling stockholder may not exercise the Equity Warrants or Exchange Warrants to the extent such exercise would cause such selling stockholder, together with its affiliates, to beneficially own a number of shares of Common Stock that would exceed 4.99% or 9.99%, as applicable, of our then outstanding shares of Common Stock following such exercise, excluding for purposes of such determination shares of Common Stock issuable upon exercise of the Equity Warrants or Exchange Warrants which have not been exercised. Similarly the Escrow Shares may not be released to the selling stockholder by the escrow agent to the extent such release would cause the selling stockholder, together with its affiliates, to beneficially own a number of shares of Common Stock that would exceed 9.99% of our then outstanding shares of Common Stock following such release. The number of shares beneficially owned prior to the offering in the second column (i) is based on 2,956,354 shares of our Common Stock, outstanding as of September 15, 2023, and (ii) takes into account the beneficial ownership limitations described above.
The third column lists the shares of Common Stock being offered by this prospectus by the selling stockholders. In accordance with the terms of our registration rights agreement with the selling stockholders, this prospectus generally covers the resale of the maximum number of shares of Common Stock issuable upon exercise of the Warrants, without regard to any limitations on the exercise of the Warrants, and this registration statement registers the maximum number of shares of Common Stock as shall from time to time be necessary to effect the exercise of the Warrants then outstanding without giving effect to any limitation on exercise included in the Warrants. The number and percentage of shares beneficially owned after the offering in the fourth and fifth columns (i) is based on 2,956,354 shares of our Common Stock outstanding as of September 15, 2023, (ii) assumes the sale of all of the shares offered by the selling stockholders pursuant to this prospectus and (iii) takes into account the beneficial ownership limitations described above. This table was prepared based on information furnished to us by the selling stockholders.

PLAN OF DISTRIBUTION
We are registering the shares of Common Stock issuable upon exercise of the Warrants to permit the resale of these shares of Common Stock from time to time after the date of this prospectus. We will not receive any of the proceeds from the sale by the selling stockholders of the shares of Common Stock. We will bear all fees and expenses incident to our obligation to register the shares of Common Stock.
The selling stockholders may sell all or a portion of the shares of Common Stock they acquire upon exercise of the Warrants beneficially owned by them and offered hereby from time to time directly or through one or more underwriters, broker-dealers or agents. If the shares of Common Stock are sold through underwriters or broker-dealers, the selling stockholders will be responsible for underwriting discounts or commissions or agent’s commissions. The shares of Common Stock may be sold in one or more transactions at fixed prices, at prevailing market prices at the time of the sale, at varying prices determined at the time of sale, or at negotiated prices. These sales may be effected in transactions, which may involve crosses or block transactions,
on any national securities exchange or quotation service on which the securities may be listed or quoted at the time of sale;
in the over-the-counter market;
in transactions otherwise than on these exchanges or systems or in the over-the-counter market;
through the writing of options, whether such options are listed on an options exchange or otherwise;
ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;
block trades in which the broker-dealer will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction;
purchases by a broker-dealer as principal and resale by the broker-dealer for its account;
an exchange distribution in accordance with the rules of the applicable exchange;
privately negotiated transactions;
short sales;
sales pursuant to Rule 144;
broker-dealers may agree with the selling stockholders to sell a specified number of such shares at a stipulated price per share;
a combination of any such methods of sale; and
any other method permitted pursuant to applicable law.
If the selling stockholders effect such transactions by selling shares of Common Stock to or through underwriters, broker-dealers or agents, such underwriters, broker-dealers or agents may receive commissions in the form of discounts, concessions or commissions from the selling stockholders or commissions from purchasers of the shares of Common Stock for whom they may act as agent or to whom they may sell as principal (which discounts, concessions or commissions as to particular underwriters, broker-dealers or agents may be in excess of those customary in the types of transactions involved). In connection with sales of the shares of Common Stock or otherwise, the selling stockholders may enter into hedging transactions with broker-dealers, which may in turn engage in short sales of the shares of Common Stock in the course of hedging in positions they assume. The selling stockholders may also sell shares of Common Stock short and deliver shares of Common Stock covered by this prospectus to close out short positions and to return borrowed shares in connection with such short sales. The selling stockholders may also loan or pledge shares of Common Stock to broker-dealers that in turn may sell such shares.
9


The selling stockholders may pledge or grant a security interest in some or all of the Warrants or shares of Common Stock they acquire upon the exercise of Warrants owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of Common Stock from time to time pursuant to this prospectus or any amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act of 1933, as amended, amending, if necessary, the list of selling stockholders to include the pledgee, transferee or other successors in interest as selling stockholders under this prospectus. The selling stockholders also may transfer and donate the shares of Common Stock in other circumstances in which case the transferees, donees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus.
The selling stockholders and any broker-dealer participating in the distribution of the shares of Common Stock may be deemed to be “underwriters” within the meaning of the Securities Act, and any commission paid, or any discounts or concessions allowed to, any such broker-dealer may be deemed to be underwriting commissions or discounts under the Securities Act. At the time a particular offering of the shares of Common Stock is made, a prospectus supplement, if required, will be distributed which will set forth the aggregate amount of shares of Common Stock being offered and the terms of the offering, including the name or names of any broker-dealers or agents, any discounts, commissions and other terms constituting compensation from the selling stockholders and any discounts, commissions or concessions allowed or reallowed or paid to broker-dealers.
Under the securities laws of some states, the shares of Common Stock may be sold in such states only through registered or licensed brokers or dealers. In addition, in some states the shares of Common Stock may not be sold unless such shares have been registered or qualified for sale in such state or an exemption from registration or qualification is available and is complied with.
There can be no assurance that any selling stockholder will sell any or all of the shares of Common Stock registered pursuant to the registration statement, of which this prospectus forms a part.
The selling stockholders and any other person participating in such distribution will be subject to applicable provisions of the Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder, including, without limitation, Regulation M of the Exchange Act, which may limit the timing of purchases and sales of any of the shares of Common Stock by the selling stockholders and any other participating person. Regulation M may also restrict the ability of any person engaged in the distribution of the shares of Common Stock to engage in market-making activities with respect to the shares of Common Stock. All of the foregoing may affect the marketability of the shares of Common Stock and the ability of any person or entity to engage in market-making activities with respect to the shares of Common Stock.
We will pay all expenses of the registration of the shares of Common Stock issuable upon exercise of the Warrants pursuant to the registration rights agreement, estimated to be $61,925 in total, including, without limitation, Securities and Exchange Commission filing fees and expenses of compliance with state securities or “blue sky” laws; provided, however, that a selling stockholder will pay all underwriting discounts and selling commissions, if any. We will indemnify the selling stockholders against liabilities, including some liabilities under the Securities Act, in accordance with the registration rights agreements, or the selling stockholders will be entitled to contribution. We may be indemnified by the selling stockholders against civil liabilities, including liabilities under the Securities Act, that may arise from any written information furnished to us by the selling stockholder specifically for use in this prospectus, in accordance with the related registration rights agreement, or we may be entitled to contribution.
Once sold under the registration statement, of which this prospectus forms a part, the shares of Common Stock will be freely tradable in the hands of persons other than our affiliates.

Item 15. Indemnification of Directors and Officers
Section 145 of the Delaware General Corporation Law (“DGCL”) authorizes a corporation to indemnify its directors and officers against liabilities arising out of actions, suits and proceedings to which they are made or threatened to be made a party by reason of the fact that they have served or are currently serving as a director or officer to a corporation. The indemnity may cover expenses (including attorneys’ fees) judgments, fines and amounts paid in settlement actually and reasonably incurred by the director or officer in connection with any such action, suit or proceeding. Section 145 permits corporations to pay expenses (including attorneys’ fees) incurred by directors and officers in advance of the final disposition of such action, suit or proceeding. In addition, Section 145 provides that a corporation has the power to purchase and maintain insurance on behalf of its directors and officers against any liability asserted against them and incurred by them in their capacity as a director or officer, or arising out of their status as such, whether or not the corporation would have the power to indemnify the director or officer against such liability under Section 145.
We have adopted provisions in our amended and restated certificate of incorporation and our amended and restated bylaws that limit or eliminate the personal liability of our directors to the fullest extent permitted by the DGCL, as it now exists or may in the future be amended. Consequently, a director will not be personally liable to us or our stockholders for monetary damages or breach of fiduciary duty as a director, except for liability for:
any breach of the director’s duty of loyalty to us or our stockholders;
any act or omission not in good faith or that involves intentional misconduct or a knowing violation of law;
any unlawful payments related to dividends or unlawful stock purchases, redemptions or other distributions; or
any transaction from which the director derived an improper personal benefit.
These limitations of liability do not alter director liability under the federal securities laws and do not affect the availability of equitable remedies such as an injunction or rescission.
In addition, our bylaws provide that:
we will indemnify our directors, officers and, in the discretion of our board of directors, certain employees to the fullest extent permitted by the DGCL, as it now exists or may in the future be amended; and
we will advance reasonable expenses, including attorneys’ fees, to our directors and, in the discretion of our board of directors, to our officers and certain employees, in connection with legal proceedings relating to their service for or on behalf of us, subject to limited exceptions.
II-1


We have entered into indemnification agreements with each of our directors, and intend to enter into such agreements with our executive officers. These agreements provide that we will indemnify each of our directors, our executive officers and, at times, their affiliates to the fullest extent permitted by Delaware law. We will advance expenses, including attorneys’ fees (but excluding judgments, fines and settlement amounts), to each indemnified director, executive officer or affiliate in connection with any proceeding in which indemnification is available and we will indemnify our directors and officers for any action or proceeding arising out of that person’s services as a director or officer brought on behalf of us or in furtherance of our rights. Additionally, certain of our directors or officers may have certain rights to indemnification, advancement of expenses or insurance provided by their affiliates or other third parties, which indemnification relates to and might apply to the same proceedings arising out of such director’s or officer’s services as a director referenced herein. Nonetheless, we have agreed in the indemnification agreements that our obligations to those same directors or officers are primary and any obligation of such affiliates or other third parties to advance expenses or to provide indemnification for the expenses or liabilities incurred by those directors are secondary.

Item 17. Undertakings
The undersigned registrant hereby undertakes:
(1)To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:
(i)To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933,
(ii)To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement, and
(iii)To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;
Provided, however, that paragraphs (1)(i), (1)(ii) and (1)(iii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.
(2)That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
(3)To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
(4)That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:
(i)Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and
(ii)Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made
II-3


in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.
(5)That, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

Ladies and Gentlemen:
We have acted as legal counsel to GRI Bio, Inc., a Delaware corporation (the “Company”), in connection with the preparation and filing with the Securities and Exchange Commission (the “Commission”) of a Registration Statement on Form S-3 (the “Registration Statement”) on October 13, 2023 under the Securities Act of 1933, as amended (the “Securities Act”). The Registration Statement relates to the registration for resale, on a delayed or continuous basis, by the selling stockholders named in the Registration Statement (the “Selling Stockholders”) of up to an aggregate of 4,134,201 shares (the “Warrant Shares”) of the Company’s common stock, $0.0001 par value per share (“Common Stock”), issuable upon the exercise of certain outstanding warrants (the “Warrants”). This opinion is being rendered in connection with the filing of the Registration Statement with the Commission.
In connection with this opinion, we have examined and relied upon the Certificate of Incorporation and Bylaws of the Company, each as restated and/or amended to date, and such other corporate records, documents and agreements as we have considered necessary or appropriate for the purpose of rendering the opinions hereinafter set forth. In our examination, we have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to us as originals and the conformity with the originals of all documents submitted to us as copies. Upon the basis of such examination, we advise you that in our opinion that the Warrant Shares, when issued upon exercise of the Warrants in accordance with the terms thereof, will be validly issued, fully paid and non-assessable.
Our opinion is limited to the General Corporation Law of the State of Delaware, and we express no opinion with respect to the laws of any other jurisdiction. No opinion is expressed herein with respect to the qualification of the Warrant Shares under the securities or blue sky laws of any state or any foreign jurisdiction.
Please note that we are opining only as to the matters expressly set forth herein, and no opinion should be inferred as to any other matters. This opinion is based upon currently existing statutes, rules, regulations and judicial decisions, and we disclaim any obligation to advise you of any change in any of these sources of law or subsequent legal or factual developments which might affect any matters or opinions set forth herein.
We understand that you wish to file this opinion with the Commission as an exhibit to the Registration Statement in accordance with the requirements of Item 601(b)(5) of Regulation S-K promulgated under the Securities Act and to reference the firm’s name under the caption “Legal
