TABLE OF CONTENTS

i

ABOUT THIS PROSPECTUS

This prospectus is part of a registration statement that we filed with the SEC utilizing a “shelf” registration process. Under this shelf registration process, we may, over time, offer and sell up to 5,000,000 shares in the aggregate of our common stock, in each case from time to time in amounts, at prices and on terms that will be determined at the time of any such offering. In addition, the selling stockholders may offer and sell, from time to time, in one or more offerings, up to 41,564,784 shares of our common stock. This prospectus provides you with a general description of the common stock that we or the selling stockholders may offer. Each time we or the selling stockholders offer and sell shares of our common stock using this prospectus, we will provide a prospectus supplement and attach it to this prospectus and may also provide you with a free writing prospectus. The prospectus supplement and any free writing prospectus will contain more specific information about the shares of common stock being offered and sold and the specific terms of that offering. The prospectus supplement may also add, update, change, or clarify information contained in or incorporated by reference into this prospectus. Any statement that we make in this prospectus will be modified or superseded by any inconsistent statement made by us or the selling stockholders in a prospectus supplement. If there is any inconsistency between the information in this prospectus and the information in the prospectus supplement, you should rely on the information in the prospectus supplement.

The rules of the SEC allow us to incorporate by reference information into this prospectus. This means that important information is contained in other documents that are considered to be a part of this prospectus. Additionally, information that we file later with the SEC will automatically update and supersede this information. You should carefully read this prospectus, the applicable prospectus supplement, together with the additional information that is incorporated or deemed incorporated by reference in this prospectus as described under the heading “Where You Can Find More Information; Incorporation of Certain Documents by Reference,” and any applicable free writing prospectus, before making an investment in our common stock. This prospectus contains summaries of certain provisions contained in some of the documents described herein, but reference is made to the actual documents for complete information. All of the summaries are qualified in their entirety by the actual documents. Copies of the documents referred to herein have been filed, or will be filed or incorporated by reference, as exhibits to the registration statement of which this prospectus is a part. The registration statement, including the exhibits and documents incorporated or deemed incorporated by reference in this prospectus, can be read on the SEC website mentioned under the heading “Where You Can Find More Information; Incorporation of Certain Documents by Reference.”

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

The statements contained in this prospectus (including any applicable prospectus supplement) and any free writing prospectus that we may provide to you in connection with an offering of our common stock described in this prospectus, or in our other documents that are incorporated by reference herein, that are not purely historical are 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 Exchange Act, including statements regarding our expectations, hopes, intentions or strategies regarding the future. Forward-looking statements can be identified by words, such as “anticipates,” “intends,” “plans,” “seeks,” “believes,” “estimates,” “expects” and similar references to future periods, or by the inclusion of forecasts or projections. Examples of forward-looking statements include, but are not limited to, statements we make regarding the outlook for our future business and financial performance, such as those contained in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our annual report on Form 10-K for the fiscal year ended December 26, 2021, filed with the SEC on March 23, 2022 (our “Annual Report”), and our quarterly reports on Form 10-Q for the quarters ended March 27, 2022, June 26, 2022 and September 25, 2022, filed with the SEC on May 10, 2022, August 9, 2022 and November 7, 2022, respectively (our “Quarterly Reports”), which are incorporated by reference herein. See “Where You Can Find More Information; Incorporation of Certain Documents by Reference.”

Forward-looking statements are based on our current expectations and assumptions regarding our business, the economy and other future conditions. Because forward-looking statements relate to the future, by their nature, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict. As a result, our actual results may differ materially from those contemplated by the forward-looking statements. Important factors that could cause actual results to differ materially from those in the forward-looking statements include regional, national or global political, economic, business, competitive, market and regulatory conditions and the following:

5

See “Risk Factors” contained elsewhere in, and incorporated by reference into, this prospectus or any applicable prospectus supplement from our filings with the SEC, including our Annual Report, Quarterly Reports and our subsequent filings with the SEC, as incorporated by reference into this prospectus.

For the reasons described above, we caution you against relying on any forward-looking statements, which should also be read in conjunction with the other cautionary statements that are incorporated by reference herein. Any forward-looking statement speaks only as of the date on which we make it. Factors or events that could cause our actual results to differ may emerge from time to time, and it is not possible for us to predict all of them. We undertake no obligation to update or revise any forward-looking statement, whether as a result of new information, future developments or otherwise, except as may be required by law.

RISK FACTORS

You should consider the specific risks described in our Annual Report and Quarterly Reports, the risk factors described under the caption “Risk Factors” in any applicable prospectus supplement or any free writing prospectus that we provide you in connection with an offering of shares of our common stock pursuant to this prospectus and any risk factors set forth in our other filings with the SEC that, pursuant to Sections 13(a), 13(c), 14, or 15(d) of the Exchange Act, are incorporated or deemed to be incorporated by reference in this prospectus, before making an investment decision. See “Where You Can Find More Information; Incorporation of Certain Documents by Reference.” Each of the risks described in these documents could materially and adversely affect our business, financial condition, results of operations and prospects and could result in a partial or complete loss of your investment.

Additional risks and uncertainties not presently known to us or that we currently believe to be less significant than the risk factors incorporated by reference herein may also adversely affect our business.

USE OF PROCEEDS

Unless otherwise indicated in a prospectus supplement, the net proceeds from the sale of the common stock offered by us in this prospectus will be used for general corporate purposes, including working capital, paydown of then-existing debt, capital expenditures, acquisitions and other business purposes. We may also invest the proceeds in certificates of deposit, United States government securities, certain other interest-bearing securities or money market securities. If we decide to use the net proceeds from a particular offering of common stock for a specific purpose other than as set forth above, we will describe that in the related prospectus supplement.

We will not receive any proceeds from the sale of our common stock by the selling stockholders.

9

DESCRIPTION OF CAPITAL STOCK

The following is a description of (i) the material terms of our amended and restated certificate of incorporation and amended and restated bylaws and (ii) certain applicable provisions of Delaware law. We refer you to our amended and restated certificate of incorporation and amended and restated bylaws, each of which have been filed as exhibits to the registration statement of which this prospectus is a part. For more information on how you can obtain our amended and restated certificate of incorporation and amended and restated bylaws, see “Where You Can Find More Information; Incorporation of Certain Documents by Reference.”

Authorized Capitalization

Our authorized capital stock consists of 300,000,000 shares of common stock, par value $0.01 per share and 10,000,000 shares of preferred stock, par value $0.01 per share. Unless our Board determines otherwise, we will issue all shares of our capital stock in uncertificated form.

Common Stock

Holders of our common stock are entitled to the rights set forth below.

Voting Rights

At any meeting of stockholders at which directors are to be elected, directors will be elected by a plurality of the votes cast by the holders of shares present in person or represented by proxy at the meeting and entitled to vote on the election of directors. Our stockholders do not have cumulative voting rights. Except as otherwise provided in our amended and restated certificate of incorporation, our bylaws or as required by law, all matters to be voted on by our stockholders other than matters relating to the election and removal of directors must be approved by a majority of the shares present in person or represented by proxy at the meeting and voting on the subject matter.

Dividend Rights

Holders of common stock share equally in any dividend declared by our Board, subject to the rights of the holders of any outstanding preferred stock.

Liquidation Rights

In the event of any voluntary or involuntary liquidation, dissolution, distribution of assets or winding up of our affairs, holders of our common stock would be entitled to share ratably in our assets that are legally available for distribution to stockholders after payment of liabilities. If we have any preferred stock outstanding at such time, holders of the preferred stock may be entitled to distribution and/or liquidation preferences. In either such case, we must pay the applicable distribution to the holders of our preferred stock before we may pay distributions to the holders of our common stock.

Registration Rights

Certain of our existing stockholders have certain registration rights with respect to our common stock pursuant to a registration rights agreement.

Other Rights

Our stockholders have no preemptive or other rights to subscribe for additional shares. There are no redemption, conversion or sinking fund provisions applicable to our common stock. All holders of our common stock are entitled to share equally on a share-for-share basis in any assets available for distribution to common stockholders upon our liquidation, dissolution or winding up. All outstanding shares are, and all shares offered by this prospectus will be, when sold, validly issued, fully paid and non-assessable.

10

Preferred Stock

Our Board is authorized to provide for the issuance of preferred stock in one or more series and to fix the preferences, powers and relative, participating, optional or other special rights and qualifications, limitations or restrictions thereof, including the dividend rate, conversion rights, voting rights, redemption rights and liquidation preference and to fix the number of shares to be included in any such series without any further vote or action by our stockholders. Any preferred stock so issued may rank senior to our common stock with respect to the payment of dividends or amounts upon liquidation, dissolution or winding up, or both. In addition, any such shares of preferred stock may have class or series voting rights. The issuance of preferred stock may have the effect of delaying, deferring or preventing a change in control of our company without further action by the stockholders and may adversely affect the voting and other rights of the holders of our common stock.

Anti-takeover Provisions

Our amended and restated certificate of incorporation and amended and restated bylaws contain provisions that delay, defer or discourage transactions involving an actual or potential change in control of us or change in our management. We expect that these provisions, which are summarized below, will discourage coercive takeover practices or inadequate takeover bids. These provisions are designed to encourage persons seeking to acquire control of us to first negotiate with our Board, which we believe may result in an improvement of the terms of any such acquisition in favor of our stockholders. However, they also give our Board the power to discourage transactions that some stockholders may favor, including transactions in which stockholders might otherwise receive a premium for their shares or transactions that our stockholders might otherwise deem to be in their best interests. Accordingly, these provisions could adversely affect the price of our common stock.

Classified Board of Directors

Our Board is divided into three classes, Class I, Class II and Class III, with members of each class serving staggered three-year terms. Our amended and restated certificate of incorporation provides that the authorized number of directors may be changed only by resolution of the Board. Any additional directorships resulting from an increase in the number of directors will be distributed among the three classes so that, as nearly as possible, each class will consist of one-third of the directors. Our amended and restated certificate of incorporation and our amended and restated bylaws also provide that a director may be removed by the affirmative vote of the holders of a majority of the voting power of our outstanding shares of capital stock entitled to vote generally in the election of directors, voting together as a single class, and only for cause so long as our Board is classified. Any vacancy on our Board, including a vacancy resulting from an enlargement of our Board, may be filled only by vote of a majority of our directors then in office. Our classified Board could have the effect of delaying or discouraging an acquisition of us or a change in our management.

Special Meetings of Stockholders and Advance Notice Requirements for Stockholder Meetings, Nominations and Proposals

Our amended and restated bylaws provide that special meetings of the stockholders may be called only upon the request of a majority of our Board, the Chairperson of our Board or the Chief Executive Officer. Our amended and restated bylaws prohibit the conduct of any business at an annual or special meeting other than as specified in the notice for such meeting or otherwise brought before the meeting by or at the direction of the Board or a duly authorized committee or authorized officer to whom the Board or committee delegated such authority. These provisions may have the effect of deferring, delaying or discouraging hostile takeovers or changes in control or management of our company.

Our amended and restated bylaws establish advance notice procedures with respect to stockholder proposals and the nomination of candidates for election as directors, other than nominations made by or at the direction of our Board or a committee of our Board. In order for any matter to be “properly brought” before a meeting, a

11

stockholder will have to comply with these advance notice requirements of directors, which may be filled only by a vote of a majority of directors then in office, even though less than a quorum, and not by the stockholders. Our amended and restated bylaws allow the presiding officer at a meeting of the stockholders to adopt rules and regulations for the conduct of meetings, which may have the effect of precluding the conduct of certain business at a meeting if the rules and regulations are not followed. These provisions may also defer, delay or discourage a potential acquirer from conducting a solicitation of proxies to elect the acquirer’s own slate of directors or otherwise attempting to obtain control of our company.

No Stockholder Action by Written Consent

Our amended and restated certificate of incorporation and our amended and restated bylaws provide that after the time that Advent collectively owns less than 50% of our then outstanding common stock, subject to the rights of any holders of preferred stock to act by written consent instead of a meeting, stockholder action may be taken only at an annual meeting or special meeting of stockholders and may not be taken by written consent instead of a meeting. Failure to satisfy any of the requirements for a stockholder meeting could delay, prevent or invalidate stockholder action.

Section 203 of the Delaware General Corporate Law (“DGCL”)

Our amended and restated certificate of incorporation provides that the provisions of Section 203 of the DGCL, which relate to business combinations with interested stockholders, do not apply to us. Section 203 of the DGCL prohibits a publicly held Delaware corporation from engaging in a business combination transaction with an interested stockholder (a stockholder who owns more than 15% of our common stock) for a period of three years after the interested stockholder became such unless the transaction fits within an applicable exemption, such as Board approval of the business combination or the transaction that resulted in such stockholder becoming an interested stockholder. These provisions apply even if the business combination could be considered beneficial by some stockholders. Our amended and restated certificate of incorporation contains provisions that have the same effect as Section 203 of the DGCL and provides that Advent, their respective affiliates or successors, their transferees, and any group as to which such persons are party do not constitute interested stockholders for purposes of these provisions for so long as they collectively own, directly or indirectly, 10% or more of the voting power of our then outstanding shares of voting stock. Although we have elected to opt out of the statute’s provisions, we could elect to be subject to Section 203 in the future.

Amendment to Bylaws and Certificate of Incorporation

Any amendment to our amended and restated certificate of incorporation must first be approved by a majority of our Board and if required by law, thereafter be approved by a majority of the outstanding shares entitled to vote on the amendment. Our amended and restated bylaws may be amended (x) by the affirmative vote of a majority of the directors then in office, without further stockholder action or (y) by the affirmative vote of at least a majority of the voting power of the then outstanding shares entitled to vote generally in the election of directors, voting together as a single class, without further action by our Board.

Renouncement of Corporate Opportunity

Our amended and restated certificate of incorporation provides that, except as may be expressly agreed in writing between our company and Advent, we renounce any interest or expectancy in, or in being offered an opportunity to participate in, any business opportunity that may from time to time be presented to and that may be a business opportunity for Advent or any of its managers, officers, directors, agents stockholders, members, partners, affiliates, and subsidiaries (other than our company and its subsidiaries) (“Exempted Persons”), even if the opportunity is one that we might reasonably have pursued or had the ability or desire to pursue if granted the opportunity to do so. No such Exempted Persons are liable to us for breach of any fiduciary or other duty, as a director or officer or otherwise, by reason of the fact that such person, acting in good faith, pursues or acquires any such business opportunity, directs any such business opportunity to another person or fails to present any such business opportunity, or information regarding any such business opportunity, to us.

12

Exclusive Forum

Our amended and restated certificate of incorporation provides that, unless we consent in writing to an alternative forum, the Court of Chancery of the State of Delaware or, if the Court of Chancery lacks jurisdiction, a state court located within the State of Delaware or the federal district court for the District of Delaware, shall, to the fullest extent permitted by law, be the sole and exclusive forum for any (i) derivative action or proceeding brought on our behalf, (ii) action asserting a claim of breach of a fiduciary duty or other wrongdoing by any current or former director, officer, employee, agent or stockholder to us or our stockholders, (iii) action asserting a claim arising pursuant to any provision of the DGCL, our amended and restated certificate of incorporation or our amended and restated bylaws or as to which the DGCL confers jurisdiction on the Court of Chancery of the State of Delaware, or (iv) action asserting a claim governed by the internal affairs doctrine of the law of the State of Delaware. Our amended and restated certificate of incorporation also provides that the foregoing exclusive forum provision does not apply to actions brought to enforce any liability or duty created by the Securities Act or Exchange Act, or any other claim or cause of action for which the federal courts have exclusive jurisdiction.

Our amended and restated certificate of incorporation also provides that, unless we consent in writing to an alternative forum, the federal district courts of the United States of America shall be the sole and exclusive forum for the resolution of any action asserting a claim arising under the Securities Act of 1933, as amended, or the rules and regulations promulgated thereunder. Pursuant to the Exchange Act, claims arising thereunder must be brought in federal district courts of the United States of America.

To the fullest extent permitted by law, any person or entity purchasing or otherwise acquiring or holding any interest in any shares of our capital stock shall be deemed to have notice of and consented to the forum provision in our amended and restated certificate of incorporation. In any case, stockholders will not be deemed to have waived our compliance with the federal securities laws and the rules and regulations thereunder. The enforceability of similar choice of forum provisions in other companies’ certificates of incorporation has been challenged in legal proceedings, and it is possible that a court could find these types of provisions to be inapplicable or unenforceable. Our amended and restated certificate of incorporation also provides that any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock will be deemed to have notice of and consented to this choice of forum provision. These exclusive forum provisions may have the effect of discouraging lawsuits against our directors and officers.

PLAN OF DISTRIBUTION

We and/or the selling stockholders may sell the securities from time to time pursuant to underwritten public offerings, negotiated transactions, block trades or a combination of these methods or through underwriters or dealers, through agents and/or directly to one or more purchasers. The securities may be distributed from time to time in one or more transactions:

Each time that we or any of the selling stockholders sell securities covered by this prospectus, we or the selling stockholders will provide a prospectus supplement or supplements that will describe the method of distribution and set forth the terms and conditions of the offering of such securities, including the offering price of the securities and the proceeds to us or the selling stockholders, if applicable.

Offers to purchase the securities being offered by this prospectus may be solicited directly. Agents may also be designated to solicit offers to purchase the securities from time to time. Any agent involved in the offer or sale of our securities will be identified in a prospectus supplement.

If a dealer is utilized in the sale of the securities being offered by this prospectus, the securities will be sold to the dealer, as principal. The dealer may then resell the securities to the public at varying prices to be determined by the dealer at the time of resale.

If an underwriter is utilized in the sale of the securities being offered by this prospectus, an underwriting agreement will be executed with the underwriter at the time of sale and the name of any underwriter will be provided in the prospectus supplement that the underwriter will use to make resales of the securities to the public. In connection with the sale of the securities, we, the selling stockholders, or the purchasers of securities for whom the underwriter may act as agent, may compensate the underwriter in the form of underwriting discounts or commissions. The underwriter may sell the securities to or through dealers, and those dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions from the purchasers for which they may act as agent. Unless otherwise indicated in a prospectus supplement, an agent will be acting on a best efforts basis and a dealer will purchase securities as a principal, and may then resell the securities at varying prices to be determined by the dealer.

Any compensation paid to underwriters, dealers or agents in connection with the offering of the securities, and any discounts, concessions or commissions allowed by underwriters to participating dealers will be provided in the applicable prospectus supplement. Underwriters, dealers and agents participating in the distribution of the securities may be deemed to be underwriters within the meaning of the Securities Act, and any discounts and commissions they receive and any profit they realize on resale of the securities may be deemed to be underwriting discounts and commissions. We may enter into agreements to indemnify underwriters, dealers and agents against civil liabilities, including liabilities under the Securities Act, or to contribute to payments they may be required to make in respect thereof and to reimburse those persons for certain expenses.

Any common stock will be listed on Nasdaq, but any other securities may or may not be listed on a national securities exchange. To facilitate the offering of securities, certain persons participating in the offering may engage in transactions that stabilize, maintain or otherwise affect the price of the securities. This may include over-allotments or short sales of the securities, which involve the sale by persons participating in the offering of more securities than were sold to them. In these circumstances, these persons would cover such over-allotments or short positions by making purchases in the open market or by exercising their over-allotment option, if any. In

16

addition, these persons may stabilize or maintain the price of the securities by bidding for or purchasing securities in the open market or by imposing penalty bids, whereby selling concessions allowed to dealers participating in the offering may be reclaimed if securities sold by them are repurchased in connection with stabilization transactions. The effect of these transactions may be to stabilize or maintain the market price of the securities at a level above that which might otherwise prevail in the open market. These transactions may be discontinued at any time.

In addition, any shares of common stock that qualify for sale pursuant to Rule 144 promulgated under the Securities Act, or Rule 144, may be sold under Rule 144 rather than pursuant to this prospectus. A selling stockholder that is an entity may elect to make an in-kind distribution of common stock to its members, partners, stockholders or other equityholders pursuant to the registration statement of which this prospectus forms a part by delivering a prospectus. To the extent that such members, partners, stockholders or other equityholders are not affiliates of ours, such members, partners, stockholders or other equityholders would thereby receive freely tradable shares of common stock pursuant to a distribution pursuant to the registration statement of which this prospectus forms a part.

The specific terms of any lock-up provisions in respect of any given offering will be described in the applicable prospectus supplement.

The underwriters, dealers and agents may engage in transactions with us, or perform services for us, in the ordinary course of business for which they receive compensation.

LEGAL MATTERS

Weil, Gotshal & Manges LLP, New York, New York, will pass upon the validity of the common stock offered by this prospectus. Additional legal matters may be passed upon for us or any underwriters, dealers or agents, by counsel that we will name in the applicable prospectus supplement.

EXPERTS

The financial statements incorporated in this Prospectus by reference to the Annual Report on Form 10-K for the fiscal year ended December 26, 2021 have been so incorporated in reliance on the report of PricewaterhouseCoopers LLP, an independent registered public accounting firm, given on the authority of said firm as experts in auditing and accounting.

In connection with First Watch Restaurant Group, Inc.’s initial public offering, PricewaterhouseCoopers LLP (“PwC”) completed an independence assessment to evaluate the services and relationships with the Company and its affiliates that may bear on PwC’s independence under the SEC and PCAOB independence rules for the audit period commencing December 31, 2018. PwC informed the Company that, commencing in February 2020 and continuing through June 2020, a PwC member firm was engaged to provide permissible tax compliance services to a portfolio company controlled by Advent, which currently is the majority equity holder of the Company, pursuant to a contingent fee of approximately $40,000. The existence of the contingent fee is not in accordance with the SEC and PCAOB auditor independence rules.

PwC provided an overview of the facts and circumstances surrounding the contingent fee arrangement to our audit committee and management, including the entity involved, the fees earned and other relevant factors. Considering the facts presented, our audit committee and PwC have concluded that the contingent fee would not impair PwC’s application of objective and impartial judgment on any matters encompassed within the audit engagement performed by PwC for our financial statements as of and for the fiscal year ended December 27, 2020, and that no reasonable investor would conclude otherwise.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

The following is an estimate of the various expenses to be incurred in connection with the registration of the securities being registered hereby, all of which will be borne by us.

The Registrant is governed by the DGCL. Section 145 of the DGCL provides that a corporation may indemnify any person, including an officer or director, who was or is, or is threatened to be made, a party to any threatened, pending or completed legal action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of such corporation), by reason of the fact that such person was or is an officer, director, employee or agent of such corporation or is or was serving at the request of such corporation as a director, officer, employee or agent of another corporation or enterprise. The indemnity may include expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, provided such officer, director, employee or agent acted in good faith and in a manner such person reasonably believed to be in, or not opposed to, the corporation’s best interest and, for criminal proceedings, had no reasonable cause to believe that such person’s conduct was unlawful. A Delaware corporation may indemnify any person, including an officer or director, who was or is, or is threatened to be made, a party to any threatened, pending or contemplated action or suit by or in the right of such corporation, under the same conditions, except that such indemnification is limited to expenses (including attorneys’ fees) actually and reasonably incurred by such person, and except that no indemnification is permitted without judicial approval if such person is adjudged to be liable to such corporation. Where an officer or director of a corporation is successful, on the merits or otherwise, in the defense of any action, suit or proceeding referred to above, or any claim, issue or matter therein, the corporation must indemnify that person against the expenses (including attorneys’ fees) which such officer or director actually and reasonably incurred in connection therewith.

The Registrant’s amended and restated bylaws authorize the indemnification of its officers and directors, consistent with Section 145 of the DGCL, as amended. The Registrant has entered into indemnification agreements with each of its executive officers and directors. These agreements, among other things, require the Registrant to indemnify each executive officer and director to the fullest extent permitted by Delaware law, including indemnification of expenses, such as attorneys’ fees, judgments, fines and settlement amounts incurred by the director or executive officer in any action or proceeding, including any action or proceeding by or in right of the Registrant, arising out of the person’s services as a director or executive officer.

Reference is made to Section 102(b)(7) of the DGCL, which enables a corporation in its original certificate of incorporation or an amendment thereto to eliminate or limit the personal liability of a director for violations of

II-1

the director’s fiduciary duty, except (i) for any breach of the director’s duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) pursuant to Section 174 of the DGCL, which provides for liability of directors for unlawful payments of dividends of unlawful stock purchases or redemptions, or (iv) for any transaction from which a director derived an improper personal benefit.

The Registrant maintains standard policies of insurance that provide coverage (i) to its directors and officers against loss rising from claims made by reason of breach of duty or other wrongful act and (ii) to the Registrant with respect to indemnification payments that it may make to such directors and officers.

Any underwriting agreement that the Registrant may enter into in connection with the sale of any securities registered hereunder may provide for indemnification to the Registrant’s directors and officers by the underwriters against certain liabilities.

The following exhibits are filed as part of this registration statement or incorporated by reference herein.

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;

II-2

(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 SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% 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 (i), (ii), and (iii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act 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, 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 to any purchaser:

(i)(A) 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

(B) 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 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 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;

(ii) Each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made 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

II-3

registration statement will, as to a purchaser with a time of contract of sale prior to such first use, 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 date of first use;

(5) That, for the purpose of determining liability of the registrant under the Securities Act to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv) Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) 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.

The undersigned registrant hereby undertakes to deliver or cause to be delivered with the prospectus, to each person to whom the prospectus is sent or given, the latest annual report to security holders that is incorporated by reference in the prospectus and furnished pursuant to and meeting the requirements of Rule 14a-3 or Rule 14c-3 under the Exchange Act and to deliver or cause to be delivered, to each person to whom the prospectus is sent or given, the latest quarterly report that is specifically incorporated by reference in the prospectus to provide interim financial information required to be presented by Article 3 of Regulation S-X.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers, and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit, or proceeding) is asserted by such director, officer, or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question of whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

First Watch Restaurant Group, Inc.

8725 Pendery Place, Suite 201,

Bradenton, FL 34201

Ladies and Gentlemen:

We have acted as counsel to First Watch Restaurant Group, Inc., a Delaware corporation (the “Company”), in connection with the preparation and filing with the Securities and Exchange Commission (the “Commission”) of the Company’s Registration Statement on Form S-3 filed on the date hereof (as amended, the “Registration Statement”) under the Securities Act of 1933, as amended (the “Act”), relating to, in each case as described in the Registration Statement, registering (i) the issuance, offering and sale by the Company, from time to time, of up to 5,000,000 shares in the aggregate of common stock, par value $0.01 per share (the “Common Stock”), of the Company (together with any additional shares that may be registered pursuant to Rule 462(b) under the Act, the “Primary Common Stock”) and (ii) the offering and sale by one or more stockholders of the Company named in the prospectus included in the Registration Statement (the “Selling Stockholders”) from time to time of up to 41,564,784 shares of Common Stock (the “Secondary Common Stock” and, together with the Primary Common Stock, the “Shares”).

In so acting, we have examined originals or copies (certified or otherwise identified to our satisfaction) of (i) the Amended and Restated Certificate of Incorporation of the Company filed with the Secretary of State of the State of Delaware, incorporated by reference as Exhibit 3.1 to the Registration Statement; (ii) the Amended and Restated Bylaws of the Company, incorporated by reference as Exhibit 3.2 to the Registration Statement; (iii) the Registration Statement; (iv) the prospectus contained within the Registration Statement; (v) the form of the Certificate of Common Stock of the Company, incorporated by reference as Exhibit 4.1 to the Registration Statement; and (vi) such corporate records, agreements, documents and other instruments, and such certificates or comparable documents of public officials and of officers and representatives of the Company, and have made such inquiries of such officers and representatives, as we have deemed relevant and necessary as a basis for the opinion hereinafter set forth.

In such examination, we have assumed the genuineness of all signatures, the legal capacity of all natural persons, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as certified, conformed or photostatic copies, and the authenticity of the originals of such latter documents. As to all questions of fact material to this opinion that have not been independently established, we have relied upon certificates or comparable documents of officers and representatives of the Company.

November 7, 2022 Page 2

We have also assumed that: (i) with respect to the issuance, offering and sale of shares of Primary Common Stock by the Company, the issuance (including the execution, delivery and performance thereof) and the terms of the Primary Common Stock and the terms of any offering and sale of shares of the Primary Common Stock will have been duly authorized by the Company; (ii) the Registration Statement and any amendments or supplements thereto (including any post-effective amendments) will have become, and will remain, effective and comply with all applicable laws and no stop order suspending the Registration Statement’s effectiveness will have been issued and remain in effect, in each case, at the time the Shares are offered or issued, as contemplated by the Registration Statement; (iii) the Company has timely filed all necessary reports pursuant to the Securities and Exchange Act of 1934, which are incorporated into the Registration Statement by reference; (iv) a prospectus supplement will have been prepared and filed with the Commission describing the Shares offered thereby and will at all relevant times comply with all applicable laws; (v) all shares of Primary Common Stock will be issued, offered and sold and all shares of Secondary Common Stock will be offered and sold in compliance with applicable federal and state securities laws and in the manner stated in the Registration Statement and the appropriate prospectus supplement; (vi) in the case of the issuance, offering and sale of shares of Primary Common Stock by the Company, the Company will have received the consideration therefore specified in any applicable agreement and that the consideration for such shares of Primary Common Stock will be at least equal to the par value of such shares of Primary Common Stock; (vii) any agreement with respect to the issuance, offering or sale of any Shares will have been duly authorized and validly executed and delivered by the Company and the other party or parties thereto, including in the case of the Secondary Common Stock, the Selling Stockholders; and (viii) any Shares issuable upon conversion, exercise or exchange of any Shares being offered will be duly authorized, created and, if appropriate, reserved for issuance upon such conversion, exercise or exchange.

Based on the foregoing, and subject to the qualifications stated herein, we are of the opinion that (i) the shares of Primary Common Stock, when issued and sold as contemplated by the Registration Statement, will be validly issued, fully paid and non-assessable and (ii) the shares of Secondary Common Stock are validly issued, fully paid and non-assessable.

The opinions expressed herein are limited to the corporate laws of the State of Delaware, and we express no opinion as to the effect on the matters covered by this letter of the laws of any other jurisdiction.

We hereby consent to the filing of this letter as an exhibit to the Registration Statement and to the reference to our firm under the caption “Legal Matters” in the prospectus which is a part of the Registration Statement. In giving such consent we do not hereby admit that we are in the category of persons whose consent is required under Section 7 of the Act or the rules and regulations of the Commission.

Very truly yours,
