PROSPECTUS SUPPLEMENT NO. 3

To Prospectus dated December 15, 2023

590,603 Shares of Common Stock

Offered by the Selling Stockholder

This prospectus supplement No. 3 supplements the prospectus dated December 15, 2023 (the “Prospectus”), which covers the offer and resale by the selling stockholder identified in this prospectus of up to an aggregate of 590,603 shares of our common stock, $0.0001 par value per share (the “Common Stock”), consisting of (i) 181,316 shares of Common Stock issuable upon the exercise of Series A-1 Warrants to purchase shares of Common Stock, (ii) 116,353 shares of Common Stock issuable upon the exercise of Series A-1 Warrants to purchase shares of Common Stock, which Series A-1 Warrants are issuable upon exercise of Series T Warrants, assuming that the Series T Warrants have been exercised in full by paying the Aggregate Exercise Price (as defined in the Series T Warrants) in cash, (iii) 116,353 shares of Common Stock issuable upon the exercise of Series A-2 Warrants to purchase shares of Common Stock, which Series A-2 Warrants are issuable upon exercise of Series T Warrants, assuming that the Series T Warrants have been exercised in full by paying the Aggregate Exercise Price in cash, (iv) 116,353 shares of Common Stock issuable upon the exercise of Series T Warrants to purchase shares of Common Stock (collectively, the “Warrants”), and (v) 60,228 shares of Common Stock issued upon the exercise of Exchange Warrants to purchase shares of Common Stock. We registered these shares issued or issuable upon exercise of the Warrants on behalf of the selling stockholder, to be offered and sold by them from time to time. The foregoing share numbers have been adjusted to reflect the one-for-seven reverse stock split of the Company’s Common Stock that became effective at 4:01 p.m. Eastern Time on January 29, 2024 (the “Reverse Stock Split”).

We are not selling any shares of Common Stock under the Prospectus and will not receive any proceeds from the sale by the selling stockholder of such shares. We are paying the cost of registering the shares of Common Stock covered by the Prospectus as well as various related expenses. The selling stockholder is responsible for all selling commissions, transfer taxes and other costs related to the offer and sale of their shares.

Sales of the shares by the selling stockholder may occur at fixed prices, at market prices prevailing at the time of sale, at prices related to prevailing market prices, at negotiated prices and/or at varying prices determined at the time of sale. The selling stockholder may sell shares directly or to or through underwriters, broker-dealers or agents, who may receive compensation in the form of discounts, concessions or commissions from the selling stockholder, the purchasers of the shares, or both. The selling stockholder may sell any, all or none of the securities offered by the Prospectus and we do not know when or in what amount the selling stockholder may sell their shares of Common Stock hereunder following the effective date of the registration statement of which the Prospectus forms a part. We provide more information about how the selling stockholder may sell or otherwise dispose of their shares of Common Stock in the section titled “Plan of Distribution” beginning on page 119 of the Prospectus.

You should read this prospectus supplement in conjunction with the Prospectus, including any supplements and amendments thereto. This prospectus supplement is qualified by reference to the Prospectus except to the extent that the information in the prospectus supplement supersedes the information contained in the Prospectus. This prospectus supplement is not complete without, and may not be delivered or utilized except in connection with, the Prospectus, including any supplements and amendments thereto.

Our Common Stock is listed on The Nasdaq Capital Market under the symbol “GRI.” On January 29, 2024, the last reported sale price of our Common Stock was $0.382 per share (which sale price was not adjusted to reflect the Reverse Stock Split).

Investing in our securities involves risks. See “Risk Factors” beginning on page 8 of the Prospectus.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus supplement is truthful or complete. Any representation to the contrary is a criminal offense.

Item 5.03 Regulation FD Disclosure

On January 29, 2024, GRI Bio, Inc. (the “Company”) filed with the Secretary of State of the State of Delaware an amendment (the “Certificate of Amendment”) to its amended and restated certificate of incorporation to effect a reverse stock split of the Company's common stock, par value $0.0001 per share (the “Common Stock”), at a ratio of 1-for-7 (the “Reverse Stock Split”). Pursuant to the Certificate of Amendment, the Reverse Stock Split became effective as of 4:01 p.m. Eastern Time on January 29, 2024 (the “Effective Time”) and shares of the Company’s Common Stock will begin trading on a post-split basis at the open of trading on The Nasdaq Capital Market on January 30, 2024. At the Effective Time, every seven (7) shares of the Company's issued and outstanding shares of Common Stock were automatically converted into one (1) share of Common Stock, without any change in the par value per share. In addition, proportionate adjustments will be made to the per share exercise price and the number of shares issuable upon the exercise of all outstanding stock options, warrants and convertible securities, and to the number of shares issued and issuable under the Company's stock incentive plans. No change was made to the number of shares of Common Stock authorized under the Company's amended and restated certificate of incorporation. Any stockholder who would otherwise be entitled to a fractional share of Common Stock created as a result of the Reverse Stock Split is entitled to receive a cash payment in lieu thereof equal to the fractional share to which the stockholder would otherwise be entitled multiplied by the closing sales price of a share of Common Stock on The Nasdaq Capital Market on January 29, 2024, as adjusted for the Reverse Stock Split.

Following the Reverse Stock Split, the shares of Common Stock will continue to trade on The Nasdaq Capital Market under the symbol "GRI." The new CUSIP number for the Common Stock following the Reverse Stock Split will be 3622AW 205.

The summary of the Certificate of Amendment contained herein does not purport to be complete and is qualified in its entirety by reference to the full text of the Certificate of Amendment, a copy of which is attached as Exhibit 3.1 of this Current Report on Form 8-K and incorporated herein by reference.

Exhibit 3.1

CERTIFICATE OF AMENDMENT
OF
AMENDED AND RESTATED CERTIFICATE OF INCORPORATION

The corporation organized and existing under the General Corporation Law of the State of Delaware, hereby certified that:

FIRST: The name of the corporation is GRI Bio, Inc. (the “Corporation”).

SECOND: The Amended and Restated Certificate of Incorporation of the Corporation, as amended to date, is hereby further amended by striking Section 4.1 of Article IV in its entirety and by substituting in lieu of the following:

“Section 4.1 Authorized Stock. The total number of shares which the Corporation shall have authority to issue is 260,000,000 shares, of which (a) 250,000,000 shall be designated as Common Stock, $0.0001 par value per share (the “Common Stock”) and (b) 10,000,000 shall be designated Preferred Stock, $0.0001 par value per share (the “Preferred Stock”).

Effective at 4:01 p.m. Eastern Time on January 29, 2024 (the “Reverse Stock Split Effective Time”), a one-for-seven reverse stock split of the Corporation’s Common Stock shall become effective, pursuant to which each seven (7) shares of Common Stock outstanding and held of record by each stockholder of the Corporation (including treasury shares) immediately prior to the Reverse Stock Split Effective Time shall be reclassified and combined into one (1) validly issued, fully paid and nonassessable share of Common Stock automatically and without any action by the holder thereof upon the Reverse Stock Split Effective Time and shall represent one share of Common Stock from and after the Reverse Stock Split Effective Time (such reclassification and combination of shares, the “Reverse Stock Split”). No fractional shares of Common Stock shall be issued as a result of the Reverse Stock Split and, in lieu thereof, upon surrender after the Reverse Stock Split Effective Time of a certificate which formerly represented shares of Common Stock that were issued and outstanding immediately prior to the Reverse Stock Split Effective Time, any person who would otherwise be entitled to a fractional share of Common Stock as a result of the Reverse Stock Split, following the Reverse Stock Split Effective Time, shall be entitled to receive a cash payment equal to the fraction of a share of Common Stock to which such holder would otherwise be entitled multiplied by the fair value per share of the Common Stock immediately prior to the Reverse Stock Split Effective Time as determined by the Board of Directors of the Corporation.

Each stock certificate that, immediately prior to the Reverse Stock Split Effective Time, represented shares of Common Stock that were issued and outstanding immediately prior to the Reverse Stock Split Effective Time shall, from and after the Reverse Stock Split Effective Time, automatically and without the necessity of presenting the same for exchange, represent that number of whole shares of Common Stock after the Reverse Stock Split Effective Time into which the shares formerly represented by such certificate have been reclassified (as well as the right to receive cash in lieu of fractional shares of Common Stock after the Reverse Stock Split Effective Time); provided, however, that each person of record holding a certificate that represented shares of Common Stock that were issued and outstanding immediately prior to the Reverse Stock Split Effective Time shall receive, upon surrender of such certificate, a new certificate evidencing and representing the number of whole shares of Common Stock after the Reverse Stock Split Effective Time into which the shares of Common Stock formerly represented by such certificate shall have been reclassified.”

THIRD: The amendment of the Amended and Restated Certificate of Incorporation herein certified has been duly adopted in accordance with the provisions of Section 242 of the General Corporation Law of the State of Delaware.

Exhibit 99.1

GRI Bio Announces Reverse Stock Split

GRI’s common stock is expected to begin trading on a post-split adjusted basis on January 30, 2024

LA JOLLA, CA, January 26, 2024 – GRI Bio, Inc. (NASDAQ: GRI) (“GRI Bio” or the “Company”), a biotechnology company advancing an innovative pipeline of Natural Killer T (“NKT”) cell modulators for the treatment of inflammatory, fibrotic and autoimmune diseases, today announced that the board of directors of the Company approved a 1-for-7 reverse stock split (the “Reverse Split”) of the Company’s common stock. The Reverse Split was approved by the stockholders of the Company at a special meeting of the Company held on January 19, 2024. The Reverse Split will legally take effect at 4:01 p.m. Eastern Time, on January 29, 2023. The Company’s common stock will open for trading under a new CUSIP number 3622AW 205 on The Nasdaq Capital Market on January 30, 2024, on a split-adjusted basis under the current ticker symbol “GRI.” The Reverse Split is intended to increase the per share trading price of the Company’s common stock to enable the Company to regain compliance with the minimum bid price requirement for continued listing on The Nasdaq Capital Market.

The 1-for-7 Reverse Split will automatically convert every 7 current shares of the Company’s common stock into one share of common stock. No fractional shares will be issued in connection with the reverse stock split. Stockholders who would otherwise hold a fractional share of the Company’s common stock following the reverse stock split will receive a cash payment in lieu thereof at a price equal to that fractional share to which the stockholder would otherwise be entitled multiplied by the closing sale price of the common stock on The Nasdaq Capital Market, as adjusted for the reverse stock split, on January 29, 2024.

The reverse split will reduce the number of shares of outstanding common stock from approximately 4,520,233 shares, the number of shares outstanding as of January 22, 2024, to approximately 645,736 shares. The total authorized number of shares will not be reduced. Proportional adjustments will also be made to the exercise and conversion prices of the Company’s outstanding stock options, warrants, and convertible securities, and to the number of shares issued and issuable under the Company’s stock incentive plans.

Stockholders holding their shares electronically in book-entry form are not required to take any action to receive post-split shares. Stockholders owning shares through a bank, broker, or other nominee will have their positions automatically adjusted to reflect the reverse stock split, subject to brokers’ particular processes, and will not be required to take any action in connection with the reverse stock split. For those stockholders holding physical stock certificates, the Company’s transfer agent, Broadridge Corporate Issuers Solutions, Inc., will send instructions for exchanging those certificates for shares held electronically in book-entry form or for new certificates, in either case representing the post-split number of shares, and any payments in cash in lieu of fractional shares, if applicable.

About GRI Bio, Inc.

GRI Bio is a clinical-stage biopharmaceutical company focused on fundamentally changing the way inflammatory, fibrotic and autoimmune diseases are treated. GRI Bio’s therapies are designed to target the activity of Natural Killer T cells, which are key regulators earlier in the inflammatory cascade, to interrupt disease progression and restore the immune system to homeostasis. NKT cells are innate-like T cells that share properties of both NK and T cells and are a functional link between the innate and adaptive immune responses.

The Company is also developing a pipeline of novel type 2 NKT agonists for the treatment of systemic lupus erythematosus. Additionally, with a library of over 500 proprietary compounds, GRI Bio has the ability to fuel a growing pipeline.
