Notice of Annual and Special Meeting of Shareholders (the “Notice”)

The 2026 annual and special meeting of shareholders (the “Meeting”) of Green Thumb Industries Inc., a British Columbia corporation (the “Corporation” or the “Company”), will be a virtual meeting held on June 16, 2026 beginning at 2:00 p.m. (Central time), at www.virtualshareholdermeeting.com/GTBIF2026.

The following matters will be considered at the Meeting:

This Notice is accompanied by the proxy statement and the accompanying form of proxy (“Proxy Instrument”). As permitted by applicable securities law, the Company is using “Notice-and-Access” to deliver the proxy statement to shareholders. This means that the proxy statement is being posted online to access, rather than being mailed out. Notice-and-Access substantially reduces the Company’s printing and mailing costs and is environmentally friendly as it reduces paper and energy consumption. The proxy statement, the audited annual consolidated financial statements of the Company for the fiscal year ended December 31, 2025, together with the notes thereto, the independent auditor’s report thereon and the related management’s discussion and analysis are available on the Investors page of the Company’s website at gtigrows.com, Canada’s System for Electronic Data Analysis and Retrieval (“SEDAR+”) at www.sedarplus.ca and the Securities and Exchange Commission’s website at www.sec.gov. Shareholders will still receive a Proxy Instrument or a voting instruction form in the mail so they can vote their shares but, instead of receiving a paper copy of the proxy statement, they will receive a notice with information about how they can access the proxy statement electronically and how to request a paper copy.

The record date for the determination of shareholders of the Company entitled to receive notice of and to vote at the Meeting or any adjournment(s) thereof is April 20, 2026 (the “Record Date”). Shareholders of the Company whose names have been entered in the register of shareholders of the Company at the close of business on the Record Date will be entitled to receive notice of and to vote at the Meeting or any adjournment(s) thereof.

A shareholder of the Company may attend the Meeting live via webcast or may be represented by proxy. Registered shareholders of the Company who are unable to attend the Meeting or any adjournment(s) thereof via the webcast are requested to date, sign and return the accompanying Proxy Instrument for use at the Meeting or any adjournment(s) thereof.

To be effective, the enclosed Proxy Instrument must be returned to our proxy tabulator, Broadridge Financial Solutions (“Broadridge”) by mail using the enclosed return envelope to Vote Processing, c/o Broadridge, 51 Mercedes Way, Edgewood, NY 11717. Alternatively, you may vote by Internet at www.proxyvote.com and clicking “Vote” or by calling 1-800-690-6903. All instructions are listed on the enclosed Proxy Instrument. Your proxy or voting instructions must be received in each case no later than 10:59 p.m. (Central Time) on June 12, 2026 or, if the Meeting is adjourned, at least 48 hours (excluding Saturdays, Sundays and statutory holidays in the Province of British Columbia) before the beginning of any adjournment(s) to the Meeting.

Whether or not you plan to attend the Meeting via live webcast, we encourage you to read this proxy statement and promptly vote your shares. For specific instructions on how to vote your shares, please refer to the section entitled “How You Can Vote” and to the instructions on your proxy or voting instruction card.

Proxy Materials

Why am I receiving these materials?

Our Board is using this proxy statement to solicit proxies for use at the Meeting to be held via live webcast on June 16, 2026 and is making these materials available by posting them online to access, rather than mailing them out unless requested by a shareholder. The cost of any solicitation will be borne by the Company. Proxies may also be solicited personally by employees of the Company at nominal cost to the Company.

As a shareholder, you are invited to attend the Meeting and are entitled and requested to vote on the business items described in this proxy statement. This proxy statement is furnished in connection with the solicitation of proxies by or on behalf of management of the Company and the Board. This proxy statement is designed to assist you in voting your shares and includes information that we are required to provide under the rules of the SEC and applicable Canadian securities laws.

These proxy materials are being sent to both registered and non-registered shareholders. In some instances, the Company has distributed copies of the Notice, the proxy statement and the accompanying Proxy Instrument (collectively, the “Documents”) to clearing agencies, securities dealers, banks and trust companies, or their nominees (collectively “Intermediaries”, and each an “Intermediary”) for onward distribution to non-registered shareholders whose shares are held by or in the custody of those Intermediaries (“Non-registered Shareholders” or “beneficial owners”). The Intermediaries are required to forward the Documents to Non-registered Shareholders.

Solicitation of proxies from Non-registered Shareholders will be carried out by Intermediaries, or by the Company if the names and addresses of Non-registered Shareholders are provided by the Intermediaries.

Non-registered Shareholders who have received the Documents from their Intermediary should follow the directions of their Intermediary with respect to the procedure to be followed for voting at the Meeting. Generally, Non-registered Shareholders will either:

Your Intermediary is responsible for: (i) delivering the Documents to you; and (ii) executing your proper voting instructions. Non-registered Shareholders who have elected to receive the Documents by electronic delivery (“e-Delivery”) will have received e-mail notification from the Intermediary that the Documents are available electronically on the Company’s website. Please return your voting instructions as specified in the request for voting instructions.

I share an address with another shareholder, and we received only one paper copy of the proxy materials. How may I obtain an additional copy?

If you share an address with another shareholder, you may receive only one set of proxy materials unless you have provided contrary instructions. If you wish to receive a separate set of the materials, please request the additional copy by contacting our Corporate Secretary at investorrelations@gtigrows.com or by calling us at (312) 471-6720.

A separate set of the materials will be sent promptly following receipt of your request.

Who pays the cost of soliciting proxies for the Meeting?

We will bear the cost of solicitation. This solicitation of proxies is being made to shareholders by mail, but may be supplemented by telephone or other personal contact.

We will not reimburse Intermediaries for forwarding proxy materials to objecting beneficial owners and such objecting beneficial owners will not receive proxy materials unless their Intermediaries assume the cost of delivery.

What items of business will be voted on at the Meeting?

The business items to be voted on at the Meeting are to:

What are my voting choices?

You may vote “FOR” or “AGAINST” for the setting of the number of directors at seven; “FOR” or “WITHHOLD” for the election of each director nominee; “FOR,” “AGAINST” OR “ABSTAIN” for the Say-on-Pay Proposal; “FOR” or “WITHHOLD” for the re-appointment of Baker Tilly as auditors for the ensuing year and the authorization of the Board to fix the auditor’s remuneration and set the terms of engagement; and “FOR,” “AGAINST” or “ABSTAIN” for the Amendment Proposal.

How does the Board recommend that I vote?

Our Board recommends that you vote your shares “FOR” the setting of the number of directors at seven; “FOR” each of its nominees for election to the Board; “FOR” the Say-on-Pay Proposal; and “FOR” the re-appointment of Baker Tilly, as auditors for fiscal 2025 and the authorization of the Board to fix the auditor’s remuneration and set the terms of engagement; and the independent members of our Board recommend that you vote “FOR” the Amendment Proposal.

What vote is required to approve each item?

To conduct business at the Meeting, the quorum of shareholders is one person who holds, or who represents by proxy one or more shareholders who in the aggregate hold, at least 5% of the issued shares entitled to be voted at the Meeting.

If you indicate “WITHHOLD” in respect to the election of directors, your vote will be counted for purposes of determining the presence or absence of a quorum for the transaction of business at the Meeting. As described below, broker non-votes will be counted for determining the presence or absence of a quorum for the transaction of business at the Meeting, but will not be considered votes cast with respect to the election of any director nominee or on any other proposal. Abstentions will also not be treated as votes cast and will not be counted in the determination of the outcome of the Say-on-Pay Proposal, the Amendment Proposal or any other proposal.

What happens if additional items are presented at the Meeting?

As of the date of this proxy statement, management of the Company knows of no such amendments, variations or other matters to come before the Meeting. However, if other matters properly come before the Meeting, it is the intention of the persons named in the enclosed Proxy Instrument to vote such proxy according to their best judgment.

Where can I find the voting results?

We expect to announce preliminary voting results at the Meeting and to publish final results in a current report on Form 8-K that we will file with the SEC promptly following the Meeting. The Form 8-K will also be available on SEDAR+ and on the Investors page of our website gtigrows.com.

How You Can Vote

What shares can I vote?

You are entitled to vote all shares owned by you on the Record Date, including (1) shares held directly in your name as the shareholder of record and (2) shares held for you as the beneficial owner through an Intermediary. On the Record Date, there were 808 shareholders of record holding (i) 202,467,229 Subordinate Voting Shares; (ii) 37,472 Multiple Voting Shares; and (iii) 201,690 Super Voting Shares.

REGISTERED SHAREHOLDERS HAVE THE RIGHT TO APPOINT A PERSON TO REPRESENT THEM AT THE MEETING OTHER THAN THE PERSON(S) DESIGNATED IN THE PROXY INSTRUMENT either by striking out the names of the persons designated in the Proxy Instrument and by inserting the name of the person or company to be appointed in the space provided in the Proxy Instrument or by completing another proper form of proxy and, in either case, delivering the completed proxy to Broadridge by mail using the enclosed return envelope to Vote Processing, c/o Broadridge, 51 Mercedes Way, Edgewood, NY 11717. Alternatively, you may vote by Internet at www.proxyvote.com and clicking “Vote” or by calling 1-800-690-6903.

What is the difference between holding shares as a shareholder of record and as a beneficial owner?

Most of our shareholders hold their shares through an Intermediary, such as a bank, broker or other nominee rather than having the shares registered directly in their own name. Summarized below are some distinctions between shares held of record and those owned beneficially.

Shareholder of Record

If your shares are registered directly in your name with our transfer agent, Odyssey Trust Company, you are the shareholder of record of the shares. As the shareholder of record, you have the right to grant a proxy to vote your shares to representatives from the Company or to another person, or to vote your shares electronically at the Meeting. You have received a proxy card to use in voting your shares either by mail or email.

Beneficial Owner

If your shares are held through an Intermediary such as a bank, broker, plan trustee or other nominee, it is likely that they are registered in the name of the Intermediary and you are the beneficial owner of shares held in street name.

As the beneficial owner of shares held for your account, you have the right to direct the registered holder to vote your shares as you instruct, and you also are invited to attend the Meeting. Your Intermediary has provided a voting instruction card for you to use in directing how your shares are to be voted. However, since a beneficial owner is not the shareholder of record, you may not vote your shares electronically at the Meeting, or any adjournment(s) or postponement(s) thereof, unless you obtain a legal proxy from the registered holder of the shares giving you the right to do so.

How can I vote at the Meeting?

You may vote electronically at the Meeting or any adjournment(s) or postponement(s) thereof, those shares that you hold in your name as the shareholder of record. You may vote electronically at the Meeting or any adjournment(s) or postponement(s) thereof, shares for which you are the beneficial owner only by obtaining a legal proxy giving you the right to vote the shares from the Intermediary that is the registered holder of your shares.

Even if you plan to attend the Meeting, we recommend that you also submit your proxy or voting instructions in advance as described below, so that your vote will be counted if you later decide not to attend.

How can I vote without attending the Meeting?

Whether you hold your shares as a shareholder of record or as a beneficial owner, you may direct how your shares are to be voted without attending the Meeting or any adjournment(s) or postponement(s) thereof. If you are a shareholder of record, you may vote by submitting a proxy. If you hold shares as a beneficial owner, you may vote by submitting voting instructions to the registered owner of your shares. Each registered shareholder submitting a proxy has the right to appoint one or more proxy holders (but not more than five) to represent the shareholder at the Meeting to the extent and with the powers conferred by the proxy.

For directions on how to vote, please refer to the following instructions and those included on your proxy or voting instruction card. A proxy form will not be valid unless completed and deposited in accordance with the instructions set out in the proxy form.

Voting by Internet

Shareholders may vote over the Internet by following the instructions on the proxy or voting instruction card.

Voting by Mail

Shareholders may vote by mail by signing, dating and returning their proxy or voting instruction card to our proxy tabulator, Broadridge, at the following address:

Vote Processing, c/o Broadridge

51 Mercedes Way

Edgewood, NY 11717

How do I attend the virtual Meeting?

This year’s Meeting will again be a completely virtual meeting of shareholders, which will be conducted via live webcast. You are entitled to participate in the Meeting only if you were a registered shareholder as of the close of business on April 20, 2026 or if you hold a valid proxy to vote at the Meeting.

You will be able to attend the Meeting online and submit your questions during the Meeting by visiting www.virtualshareholdermeeting.com/GTBIF2026. You will also be able to vote your shares electronically at the Meeting. To participate, you will need your 16-digit control number that is included in your proxy materials, on your proxy card, or on the instructions that accompanied your proxy materials.

The Meeting will begin promptly at 2:00 p.m., Central time. We encourage you to access the Meeting prior to the start time. Online access will open at 1:45 p.m., Central time, and you should allow ample time to log in to the Meeting webcast and test your computer audio system. Technical assistance will be available if you have difficulty logging into the Meeting via a telephone number that will be posted on the login page to the Meeting.

We recommend that you carefully review the procedures needed to gain admission in advance. If you do not comply with the procedures described here for attending the Meeting online, you will not be able to participate online.

What will I need to attend the virtual Meeting?

If you were a shareholder of record as of the close of business on April 20, 2026, or you hold a valid proxy for the Meeting, you may attend the Meeting, vote, and submit a question during the Meeting by visiting www.virtualshareholdermeeting.com/GTBIF2026 and using your 16-digit control number to enter the Meeting. If you are not a shareholder of record but hold shares as a beneficial owner in street name, you may join the Meeting as a guest or by obtaining a proxy from the owner of record. If you do not comply with the procedures outlined above, you will not be admitted to the virtual Meeting.

Will I be able to attend the Meeting without a 16-digit control number?

Yes, you may register to attend the Meeting as a guest, but you will not be able to submit questions or comments and will not be able to vote at the Meeting without your 16-digit control number.

Why a virtual annual meeting?

We are excited to again embrace virtual meeting technology, which we believe provides expanded access, improved communications and cost and time savings for our shareholders and the Company. A virtual meeting enables increased shareholder attendance and participation from locations around the world. We believe the cost and time savings afforded by a virtual meeting encourages more shareholders to attend the Meeting and is the most appropriate format for our shareholders and other Meeting attendees.

You will be able to attend the Meeting online and submit your questions or comments during the Meeting by visiting www.virtualshareholdermeeting.com/GTBIF2026. You will also be able to vote your shares electronically at the Meeting. We encourage you to vote your shares prior to the Meeting to ensure they are represented. Even if you submit a vote prior to the Meeting, you will have an opportunity to vote again during the Meeting and automatically revoke your earlier vote.

What if during the check-in period or during the Meeting I have technical difficulties or trouble accessing the virtual meeting website?

We will have technicians ready to assist you with any technical difficulties you may have accessing the virtual Meeting. If you encounter any difficulties accessing the virtual Meeting during check-in or during the Meeting, please call the technical support number that will be posted on the virtual Meeting login page (www.virtualshareholdermeeting.com/GTBIF2026).

How do I submit questions for the Meeting?

Shareholders who wish to submit questions or comments may do so during the live webcast of the Meeting at www.virtualshareholdermeeting.com/GTBIF2026. Instructions will be available on the virtual Meeting site and technical assistance will be available.

How will my shares be voted?

Shares represented by properly executed proxies in favor of persons designated in the printed portion of the enclosed Proxy Instrument WILL, UNLESS OTHERWISE INDICATED, BE VOTED FOR THE SETTING OF THE NUMBER OF DIRECTORS AT SEVEN, FOR THE ELECTION OF EACH DIRECTOR NOMINEE, FOR THE SAY-ON-PAY PROPOSAL, FOR THE RE-APPOINTMENT OF BAKER TILLY US, LLP AS THE AUDITORS OF THE COMPANY AND FOR THE AUTHORIZATION OF THE BOARD TO FIX THE AUDITORS’ REMUNERATION AND TERMS OF ENGAGEMENT, AND FOR THE AMENDMENT PROPOSAL. The shares represented by the Proxy Instrument will be voted or withheld from voting in accordance with the instructions of the shareholder on any ballot that may be called for and, if the shareholder specifies a choice with respect to any matter to be acted upon, the shares will be voted accordingly. The enclosed Proxy Instrument confers discretionary authority on the persons named therein with respect to amendments or variations to matters identified in the Notice or other matters which may properly come before the Meeting. As of the date of this proxy statement, management of the Company knows of no such amendments, variations or other matters to come before the Meeting. However, if other matters properly come before the Meeting, it is the intention of the persons named in the enclosed Proxy Instrument to vote such proxy according to their best judgment.

Will shares I hold in my brokerage account be voted if I do not provide timely voting instructions?

If your shares are held through a brokerage firm, they will be voted as you instruct on the voting instruction card provided by your broker. If you sign and return your card without giving specific instructions, your shares will be voted in accordance with the recommendations of our Board.

If you do not return your voting instruction card on a timely basis, your broker will have the authority to vote your brokerage shares only on the proposal to re-appoint our auditor. Your broker will be prohibited from voting your shares without your instructions on setting the number of directors, the election of directors, the Say-on-Pay Proposal, the Amendment Proposal and on any other proposal. These “broker non-votes” will be counted only for the purpose of determining whether a quorum is present at the Meeting and not as votes cast. Such broker non-votes will have no effect on the outcome of the matter as they will not be deemed to be shares cast.

Will shares that I own as a shareholder of record be voted if I do not timely return my proxy card?

Shares that you own as a shareholder of record will be voted as you instruct on your proxy card. If you sign and return your proxy card without giving specific instructions, they will be voted in accordance with the procedure set out above under the heading “How will my shares be voted?”

If you do not timely return your proxy card, your shares will not be voted unless you or your proxy holder attends the Meeting via the live webcast and any adjournment(s) or postponement(s) thereof and votes electronically submitted during the Meeting as described above under the heading “How can I vote at the Meeting?”

When is the deadline to vote?

If you hold shares as the shareholder of record, your vote by proxy must be received before 10:59 p.m. (Central time) on June 12, 2026 or 48 hours prior to any adjournment(s) of the Meeting or must be deposited at the Meeting with the chairman of the Meeting before the commencement of the Meeting or any adjournment(s) thereof.

If you hold shares as a beneficial owner, please follow the voting instructions provided by your Intermediary.

May I change or revoke my vote?

A shareholder who has given a proxy pursuant to this solicitation may revoke it at any time up to and including the second business day preceding the day of the Meeting or any adjournment(s) thereof at which the proxy is to be used:

For shares you hold as a beneficial owner, you may change your vote by timely submitting new voting instructions to your Intermediary (which revokes your earlier instructions), or, if you have obtained a legal proxy from the Intermediary giving you the right to vote your shares, by attending the Meeting and voting via the live webcast.

Shareholder Proposals and Director Nominations

What is the deadline to submit shareholder proposals to be included in the proxy materials for next year’s annual meeting?

The Company is subject to the rules of both the SEC under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and provisions of the Business Corporations Act (British Columbia) (“BCBCA”) with respect to shareholder proposals, as well as the Existing Articles. As clearly indicated under the BCBCA and SEC rules under the Exchange Act, simply submitting a shareholder proposal does not guarantee its inclusion in the proxy materials.

Shareholder proposals submitted pursuant to SEC rules under the Exchange Act for inclusion in the Company’s proxy materials for next year’s annual meeting must be received by our Corporate Secretary no later than the close of business (Central time) on December 30, 2026 and must be submitted to our Corporate Secretary at Green Thumb Industries Inc., 325 West Huron Street, Suite 700, Chicago, Illinois 60654. Such proposals must also comply with all applicable provisions of Rule 14a-8 under the Exchange Act.

The BCBCA also sets out the requirements for a valid proposal and provides for the rights and obligations of the Company and the submitter upon a valid proposal being made. Proposals submitted under the applicable provisions of the BCBCA that a shareholder intends to present at next year’s annual meeting and wishes to be considered for inclusion in the Company’s proxy statement and form of proxy relating to next year’s annual meeting must be received at least three (3) months before the anniversary of the Company’s last annual general meeting (March 16, 2027). Such proposals must also comply with all applicable provisions of the BCBCA and the regulations thereunder.

Proposals that are not timely submitted or are submitted to the incorrect address or other than to the attention of our Corporate Secretary may, at our discretion, be excluded from our proxy materials.

See below under the heading “How may I nominate director candidates or present other business for consideration at a meeting?” for a description of the procedures through which shareholders may nominate director candidates for consideration.

How may I nominate director candidates or present other business for consideration at a meeting?

Shareholders who wish to (1) submit director nominees for consideration or (2) present other items of business directly at next year’s annual meeting must give written notice of their intention to do so, in accordance with the deadlines described below, to our Corporate Secretary at the address set forth below under the heading “What if I have additional questions or how do I obtain additional copies of this proxy statement or voting materials?” Any such notice also must include the information required by the Articles (which may be obtained as provided below under the heading “How may I obtain financial and other information about Green Thumb Industries Inc.?”) and must be updated and supplemented as provided in the Articles.

Written notice of director nominees must be received, in the case of an annual meeting, not less than thirty (30) days prior to the date of the annual meeting of shareholders; provided, however, that if the annual meeting of shareholders is to be held on a date that is less than fifty (50) days after the date on which the initial public announcement of the date of the annual meeting of shareholders was made, notice by the nominating shareholder may be made not later than the close of business on the tenth (10th) day following such public announcement, provided that, if Notice-and-Access (as defined in Canadian National Instrument 54-101—Communication with Beneficial Owners of Securities of a Reporting Issuer (“NI 54-101”)) is used for delivery of proxy related materials in respect of a meeting described above, and the date of such first public announcement in respect of the meeting is not less than 50 days prior to the date of the applicable meeting, the notice must be received not later than the close of business on the 40th day before the applicable meeting. See “Advance Notice Policy” under “Proposals No. 1 and 2—Election of Directors” in this proxy statement.

How may I recommend candidates to serve as directors?

Shareholders may recommend director candidates for consideration by the Board by writing to our Corporate Secretary at the address set forth below under the heading “What if I have additional questions or how do I obtain additional copies of this proxy statement or voting materials?” in accordance with the notice provisions described above under the heading “How may I nominate director candidates or present other business for consideration at a meeting?”

To be in proper written form, such notice must set forth the nominee’s (i) name, age, business and residential address and principal occupation or employment for the past five (5) years; and (ii) his or her direct or indirect beneficial ownership in, or control or direction over, any class or series of securities of the Company, including the number or principal amount and such other information on the nominee and the nominating shareholder as set forth in the Articles, which may be obtained in accordance with the instructions below under the heading “How may I obtain financial and other information about Green Thumb Industries Inc.?”

Description of the Company’s Voting Securities

The Company is authorized to issue an unlimited number of Subordinate Voting Shares, an unlimited number of Multiple Voting Shares and an unlimited number of Super Voting Shares.

On April 20, 2026, the Record Date, there were 808 shareholders of record holding (i) 202,467,229 Subordinate Voting Shares; (ii) 37,472 Multiple Voting Shares; and (iii) 201,690 Super Voting Shares.

The Subordinate Voting Shares and Multiple Voting Shares are “restricted securities” within the meaning of such term under applicable Canadian securities laws. Under Canadian securities laws, a “restricted security” means an equity security of a reporting issuer if, among other things, there is another class of securities of the reporting issuer that carries a greater number of votes per security relative to the equity security. As of the Record Date, the Subordinate Voting Shares represent approximately 49.6% of voting rights attached to outstanding securities of the Company, the Multiple Voting Shares represent approximately 0.9% of voting rights attached to outstanding securities of the Company, and the Super Voting Shares represent approximately 49.5% of voting rights attached to outstanding securities of the Company.

The total number of equity shares assuming all are converted into Subordinate Voting Shares as of the Record Date would be 226,383,429.

Holders of Subordinate Voting Shares are entitled to notice of and to attend any meeting of the shareholders of the Company, except a meeting of which only holders of another particular class or series of shares of the Company have the right to vote. At each such meeting, holders of Subordinate Voting Shares are entitled to one vote in respect of each Subordinate Voting Share held.

Holders of Multiple Voting Shares are entitled to notice of and to attend any meeting of the shareholders of the Company, except a meeting of which only holders of another particular class or series of shares of the Company have the right to vote. At each such meeting, holders of Multiple Voting Shares are entitled to one vote in respect of each Subordinate Voting Share into which such Multiple Voting Share could then be converted (currently 100 votes per Multiple Voting Share held).

Holders of Super Voting Shares are entitled to notice of and to attend any meeting of the shareholders of the Company, except a meeting of which only holders of another particular class or series of shares of the Company have the right to vote. At each such meeting, holders of Super Voting Shares are entitled to 1,000 votes per share.

Our 2025 Form 10-K, filed with the SEC on February 25, 2026, provides further information regarding our securities.

Except as set out below, to the knowledge of the directors and officers of the Company, as of April 20, 2026, no person beneficially owns or exercises control over, directly or indirectly, more than 10% of the outstanding voting securities of the Company:

Note:

Take-Over Bid Protection

Under applicable Canadian law, an offer to purchase Super Voting Shares would not necessarily require that an offer be made to purchase Subordinate Voting Shares or Multiple Voting Shares. In accordance with the rules applicable to most senior issuers in Canada, in the event of a take-over bid, the holders of Subordinate Voting Shares or of Multiple Voting Shares will be entitled to participate on an equal footing with holders of Super Voting Shares. The owners of all the outstanding Super Voting Shares entered into a customary coattail agreement with the Company and a trustee (the “Coattail Agreement”). The Coattail Agreement contains provisions customary in Canada for dual class, listed corporations designed to prevent transactions that otherwise would deprive the holders of Subordinate Voting Shares or Multiple Voting Shares of rights under applicable take-over bid legislation to which they would have been entitled if the Super Voting Shares had been Subordinate Voting Shares or Multiple Voting Shares.

The undertakings in the Coattail Agreement do not apply to prevent a sale by any initial holder of Super Voting Shares if concurrently an offer is made to purchase Subordinate Voting Shares and Multiple Voting Shares that:

In addition, the Coattail Agreement does not prevent the transfer of Super Voting Shares by an initial holder to a Permitted Holder (as that term is defined in the Existing Articles). The conversion of Super Voting Shares into Multiple Voting Shares, whether or not such Multiple Voting Shares are subsequently sold or converted into Subordinate Voting Shares, would not constitute a disposition of Super Voting Shares for the purposes of the Coattail Agreement.

Under the Coattail Agreement, any disposition of Super Voting Shares (including a transfer to a pledgee as security) by a holder of Super Voting Shares party to the agreement will be conditional upon the transferee or pledgee becoming a party to the Coattail Agreement, to the extent such transferred Super Voting Shares are not automatically converted into Multiple Voting Shares in accordance with the Existing Articles.

The Coattail Agreement contains provisions for authorizing action by the trustee to enforce the rights under the Coattail Agreement on behalf of the holders of the Subordinate Voting Shares or of the Multiple Voting Shares. The obligation of the trustee to take such action is conditional on the Company or holders of the Subordinate Voting Shares or of the Multiple Voting Shares, as the case may be, providing such funds and indemnity as the trustee may require. No holder of Subordinate Voting Shares or of Multiple Voting Shares, as the case may be, has the right, other than through the trustee, to institute any action or proceeding or to exercise any other remedy to enforce any rights arising under the Coattail Agreement unless the

trustee fails to act on a request authorized by holders of not less than 10% of the outstanding Subordinate Voting Shares or of Multiple Voting Shares, as the case may be, and reasonable funds and indemnity have been provided to the trustee. The Company has agreed to pay the reasonable costs of any action that may be taken in good faith by holders of Subordinate Voting Shares or of Multiple Voting Shares, as the case may be, pursuant to the Coattail Agreement.

The Coattail Agreement provides that it may not be amended, and no provision thereof may be waived, unless, prior to giving effect to such amendment or waiver, the following have been obtained: (i) the consent of any applicable securities regulatory authority in Canada; and (ii) the approval of at least 66 2/3% of the votes cast by holders of Subordinate Voting Shares and 66 2/3% of the votes cast by holders of Multiple Voting Shares excluding votes attached to Subordinate Voting Shares and to Multiple Voting Shares, if any, held by the initial holders, their affiliates and any persons who have an agreement to purchase Super Voting Shares on terms which would constitute a sale or disposition for purposes of the Coattail Agreement other than as permitted thereby.

No provision of the Coattail Agreement limits the rights of any holders of Subordinate Voting Shares or of Multiple Voting Shares under applicable law.

Notice-and-Access

OVERVIEW OF PROPOSALS TO BE VOTED ON

All proposals herein are included in this proxy statement at the direction of our Board. Our Board unanimously recommends that you vote “FOR” the setting of the number of directors at seven, the election of the director nominees and the compensation of our named executive officers in Proposals No. 1, 2 and 3, “FOR” the re-appointment and remuneration of auditors in Proposal No. 4, and “FOR” the Amendment Proposal in Proposal No. 5.

PROPOSALS NO. 1 AND 2—ELECTION OF DIRECTORS

The Articles provide that the number of directors should not be fewer than three directors. There are currently seven directors of the Company. It is proposed to fix the number of directors at seven and that seven directors be elected at the Meeting.

Management proposes to nominate at the Meeting the persons whose names are set forth in the table below, each to serve as a director of the Company until the next meeting of shareholders at which the election of directors is considered, or until his/her successor is duly elected or appointed, unless he/she resigns, is removed or becomes disqualified in accordance with the Articles or the BCBCA. The persons named in the accompanying Proxy Instrument intend to vote for the election of such persons at the Meeting, unless otherwise directed. Management does not contemplate that any of the nominees will be unable to serve as a director of the Company.

The following table sets out the name of each current director, each of whom is proposed by the Board to be nominated for election as a director of the Company at the Meeting, and each of their respective positions and the period during which such person has been a director of the Company.

Biographical Information

Consistent with the Company’s ongoing effort to maintain a highly qualified, independent Board with relevant expertise to guide the Company going forward, the Board believes a broad range of characteristics, including skills and experience, as well as diversity and demographic factors are important considerations in selecting director nominees. The nominees for election, whose information appears below, reflect those efforts. Following is a summary of key qualifications each nominee brings to the Board and the biographies of the nominees for the Board.

The persons named in the accompanying Proxy Instrument (if named and absent contrary directions) intend to vote the shares represented thereby “FOR” (i) setting the number of directors at seven and (ii) the election of each of the aforementioned named nominees unless otherwise instructed on a properly executed and validly deposited proxy. Management of the Company does not contemplate that any nominees named above will be unable to serve as a director but, if that should occur for any reason prior to the Meeting, the persons named in the enclosed form of proxy reserve the right to vote for another nominee at their discretion.

Replacement or Removal of Directors

To the extent directors are elected or appointed to fill casual vacancies or vacancies arising from the removal of directors, in both instances whether by shareholders or directors, the directors shall hold office until the remainder of the unexpired portion of the term of the departed director that was replaced.

Advance Notice Policy

The Articles include an advance notice policy for the nomination for election of directors (the “Advance Notice Policy”). The Advance Notice Policy provides that any shareholder seeking to nominate a candidate for election as a director (a “Nominating Shareholder”) at any annual meeting of the shareholders, or at any special meeting of shareholders if one of the purposes for which the special meeting was called was the election of directors, must give timely notice thereof in proper written form to our Chief Executive Officer.

To be timely, a Nominating Shareholder’s notice must be made: (i) in the case of an annual meeting of shareholders (including an annual and special meeting), not less than thirty (30) days prior to the date of the annual meeting of shareholders, provided, however, that in the event that the annual meeting of shareholders is to be held on a date that is less than fifty (50) days after the date on which the first public announcement of the meeting was made, notice by the Nominating Shareholder may be made not later than the close of business on the tenth (10th) day following the date of such first public announcement; and (ii) in the case of a special meeting of shareholders (which is not also an annual meeting) called for the purpose of electing directors (whether or not called for other purposes as well), not later than the close of business on the fifteenth (15th) day following the day on which the first public announcement of the date of the special meeting of shareholders was made, provided that, in either instance, if Notice-and-Access (as defined in NI 54-101) is used for delivery of proxy related materials in respect of a meeting described above, and the date of such first public announcement in respect of the meeting is not less than 50 days prior to the date of the applicable meeting, the notice must be received not later than the close of business on the 40th day before the applicable meeting. The Articles also prescribe the proper written form for a Nominating Shareholder’s notice.

In addition to satisfying the requirements under the Articles described above, to comply with the universal proxy rules under the Exchange Act, any shareholder who intends to solicit proxies in support of director nominees other than the Board’s nominees must provide notice that sets forth the information required by Rule 14a-19 under the Exchange Act no later than April 15, 2026. However, if the date of the 2026 Annual General Meeting is more than 30 days before or after the anniversary of the date of the Meeting, then such notice must be delivered by the later of (x) the 10th day following the day we first publicly announce the date of the 2026 Annual General Meeting and (y) the date which is 60 days prior to the date of the 2026 Annual General Meeting.

The chairman of the meeting shall have the power and duty to determine whether a nomination was made in accordance with the notice procedures set forth in the Articles and, if any proposed nomination is not in compliance with such provisions, the discretion to declare that such defective nomination will be disregarded.

Notwithstanding the foregoing, the Board may, in their sole discretion, waive any requirement in the Advance Notice Policy.

Corporate Cease Trade Orders, Bankruptcies Penalties or Sanctions

To the Company’s knowledge, no proposed director is or, within the ten (10) years prior to the date of this proxy statement, has been, a director, Chief Executive Officer or Chief Financial Officer of any company (including the Company) that: (i) while that person was acting in that capacity was the subject of a cease trade order or similar order, or an order that denied the relevant company access to any exemption under securities legislation, for a period of more than thirty (30) consecutive days (an “order”); or (ii) after that person ceased acting in that capacity, was subject to an order, which resulted from an event that occurred while that person was acting in the capacity of director, Chief Executive Officer or Chief Financial Officer.

To the Company’s knowledge, no proposed director is or, within the ten (10) years prior to the date hereof, has been, a director or executive officer of any company (including the Company) that, while that person was acting in that capacity, or within a year of that person ceasing to act in that capacity, became bankrupt, made a proposal under any legislation relating to bankruptcy or insolvency or was subject to or instituted any proceedings, arrangement or compromise with creditors or had a receiver, receiver manager or trustee appointed to hold its assets.

To the Company’s knowledge, no proposed director has, during the ten (10) years prior to the date hereof, become bankrupt, made a proposal under any legislation relating to bankruptcy or insolvency, or became subject to or instituted any proceedings, arrangement or compromise with creditors, or had a receiver, receiver manager or trustee appointed to hold assets of the proposed director.

Certain Relationships, Related Transactions and Policy Regarding Related Party Transactions

Policy Regarding Related Party Transactions

The Company and certain of its subsidiaries from time-to-time enter into transactions with certain “related parties.” The Company has adopted a Related Party Transactions Policy, which requires that employees, officers and directors report to the General Counsel (or chief legal officer) any activity that would cause or appear to cause a conflict of interest on his or her part. Related parties include any person who is or was (since the beginning of the last fiscal year, even if such person does not presently serve in that role) an executive officer, director or nominee for director of the Company, any shareholder owning more than 5% of any class of the Company’s voting securities or an immediate family member, as defined in the Related Party Transactions Policy, of any such person.

Under the Related Party Transactions Policy, a related party transaction includes any transaction, arrangement or relationship, or any series of similar transactions, arrangements or relationships, in which:

Pursuant to the Related Party Transactions Policy, any potential related party transaction that requires approval will be reviewed by the audit committee of the Board (the “Audit Committee”), and the Audit Committee will consider such factors as it deems appropriate to determine whether to approve, ratify or disapprove the related party transaction. The Audit Committee may approve the related party transaction only if it determines in good faith that, under all of the circumstances, the transaction is in the best interests of the Company and its shareholders.

Certain Relationships and Related Transactions

In addition to the compensation arrangements discussed under “Compensation Discussion and Analysis,” “Compensation Tables” and “Director Compensation,” below, since January 1, 2025, the Company has entered into or maintained the following related party transactions:

Lease Agreements. During 2025, the Company has continued or entered into several related party transactions with respect to lease agreements as follows:

Transactions with RYTHM, Inc. (formerly known as Agrify Corporation, and referred to herein as “RYM”). On November 5, 2024, the Company, through its indirect wholly-owned subsidiary RSLGH, LLC (“RSLGH”) purchased a significant equity interest and pre-funded warrants in RYM, a Nevada corporation with common stock traded on Nasdaq. RYM’s board of directors appointed Mr. Kovler as its Chairman and Interim Chief Executive Officer. In addition, RYM’s board of directors also appointed Armon Vakili, our Vice President - Strategic Initiatives and Partnership, as a director. As part of the transaction, the Company also acquired warrants that would allow the Company to extend its ownership stake if exercised, subject to certain beneficial ownership limitations, all of which remained outstanding as of December 31, 2025. The Company, through its subsidiaries, currently holds approximately 33% of RYM’s outstanding shares of common stock and beneficially owns 49.99% of RYM’s common stock, taking into account beneficial ownership limitations contained in the warrants and convertible notes held by subsidiaries of the Company. Of the approximately 10.9 million RYM warrants outstanding as of December 31, 2025, approximately 9.8 million are held by subsidiaries of the Company, subject to 49.99% beneficial ownership limitations, with exercise or conversion, as applicable, subject to RYM stockholder approval under the applicable Nasdaq listing rules, to the extent required. Of the approximately 3.0 million RYM shares or pre-funded warrants that would be issuable upon the conversion (excluding interest) of the RYM Notes (defined below) outstanding as of December 31, 2025, approximately 2.7 million are held by subsidiaries of the Company, subject to 49.99% beneficial ownership limitations, with exercise also subject to RYM stockholder approval under the applicable Nasdaq listing rules, to the extent required. The outstanding warrants are entitled to pro rata participation in dividends and other distributions to holders of Common Stock. The Company engaged in the following transactions with RYM in 2025:

On August 27, 2025, the Company sold to RYM an indirect wholly-owned subsidiary whose assets primarily included intellectual property rights to additional of the Company’s consumer packaged goods brands, including RYTHM, Beboe, Dogwalkers, Doctor Solomon’s, &Shine and Good Green for $50,000,000 (the “CPG Brands”). Under the purchase agreement governing the transaction, either party can cause the Company’s subsidiary to repurchase the property sold within five years of the date of the closing of the sale upon certain specified circumstances. The purchase agreement also includes rights of first refusal in favor of the Company following closing. Immediately following that sale, the Company and RYM, each through wholly-owned subsidiaries, entered into a license agreement for the Company’s exclusive use of certain intellectual property rights to use the CPG Brands in connection with the Company’s existing business in exchange for a monthly fee, payable in cash, based on sales of products using the licensed intellectual property (the “CPG Brands License Agreement“).

The Company incurred expenses of $7.8 million under these license agreements in 2025.

Effective April 1, 2026, the applicable subsidiaries of the Company and RYM amended the incredibles License Agreement and CPG Brands License Agreement to change the fees paid thereunder such that the fees payable by the Company under the incredibles License Agreement will consist of an annual cash fee of $6,000,000 payable in monthly installments and under the CPG Brands License Agreement will consist of an annual cash fee of $64,000,000

payable in monthly installments. The annual fees under both agreements will be increased on January 1 of each year during their respective terms, based on two times the amount of published consumer price index changes during the applicable period, subject to a maximum year-over-year increase of 10%.

Purchase of Super Voting Shares. On December 28, 2025, the Company purchased 2,500 Super Voting Shares of the Company from Mr. Kovler, and 2,500 Super Voting Shares from Mr. Georgiadis, at a price of $798.8 per share, which was the equivalent of $7.988 per underlying Subordinate Voting Share, the then-current market price of a Subordinate Voting Share. The total purchase price paid to each Mr. Kovler and Mr. Georgiadis was $1,997,000.

Indebtedness of Directors, Executive Officers and Employees

No individual who is, or at any time during the most recently completed fiscal year of the Company was, a director or executive officer of the Company, and no proposed nominee for election as a director of the Company, or any associate of any such director, executive officer or proposed nominee: (i) is or at any time since the beginning of the Company’s most recently completed fiscal year has been, indebted to the Company or any of its subsidiaries; or (ii) whose indebtedness to another entity is, or at any time since the beginning of the Company’s most recently completed fiscal year has been, the subject of a guarantee, support agreement, letter of credit or other similar arrangement or understanding provided by the Company or any of its subsidiaries.

Requirements under the Business Corporations Act (British Columbia)

Pursuant to the BCBCA, directors and officers are required to act honestly and in good faith with a view to the best interests of the Company. Under the BCBCA, subject to certain limited exceptions, a director who holds a disclosable interest in a material contract or transaction into which we have entered or propose to enter shall not vote on any directors’ resolution to approve the contract or transaction. A director or officer has a disclosable interest in a material contract or transaction if the director or officer:

Generally, as a matter of practice, directors or officers who have disclosed a material interest in any contract or transaction that the Board is considering will not take part in any Board discussion respecting that contract or transaction. If such directors participate in the discussions, they would abstain from voting on any matters relating to matters in which they have disclosed a disclosable interest.

Interests of Management of the Company and Others in Material Transactions

Other than as described elsewhere in this proxy statement, there are no material interests, direct or indirect, of any of our directors or executive officers, any shareholder that beneficially owns, or controls or directs (directly or indirectly), more than 10% of any class or series of our outstanding voting securities, or any associate or affiliate of any of the foregoing persons, in any transaction within the year ended December 31, 2025 that has materially affected or is reasonably expected to materially affect the Company or its subsidiaries.

OUR BOARD UNANIMOUSLY RECOMMENDS THAT YOU VOTE “FOR” THE SETTING OF THE NUMBER OF DIRECTORS AT SEVEN AND THE ELECTION OF EACH OF THE DIRECTOR NOMINEES NAMED IN PROPOSALS NO. 1 AND 2.

PROPOSAL NO. 3 – VOTE TO APPROVE, ON AN ADVISORY BASIS,

OUR EXECUTIVE COMPENSATION

We believe that our executive compensation program and policies are designed to align the interests of management with the long-term interests of our shareholders. The Company strives to provide clear and concise disclosure regarding its approach to compensation and to demonstrate how executive compensation is linked to the performance of the Company. Detailed information regarding our executive compensation program and policies, as well as the compensation of the NEOs (as that term is defined under “Compensation Discussion and Analysis” below) is set out below in the section entitled “Compensation Discussion and Analysis” and “Compensation Tables” below. We urge shareholders to read these sections including the related narrative and tabular compensation disclosure included in this proxy statement.

As required by Section 14A of the Exchange Act, we are seeking a vote on an advisory (non-binding) basis to approve the compensation of the NEOs as disclosed in this proxy statement. This proposal, commonly known as a “say-on-pay” proposal (and sometimes referred to herein as the “Say-on-Pay Proposal”), gives shareholders the opportunity to endorse or not endorse the Company’s executive compensation program and policies.

At the Meeting, shareholders will be asked to approve, on an advisory (non-binding) basis, a resolution in the form set out below, subject to such amendments, variations or additions as may be approved at the Meeting, to approve the Company’s executive compensation program and policies.

The text of the resolution to be submitted to shareholders at the Meeting is set out below:

“BE IT RESOLVED THAT the compensation paid to the Company’s named executive officers, as disclosed pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the Compensation Discussion and Analysis, compensation tables and related narrative discussion contained in the Company’s proxy statement for the Company’s 2026 Annual and Special Meeting of Shareholders, is hereby approved on a non-binding advisory basis.”

Required Vote

You may select “For”, “Against” or “Abstain” with respect to the Say-on-Pay Proposal. The affirmative vote of a simple majority of the votes cast, in person or by proxy, will constitute approval of the Say-on-Pay Proposal.

While this advisory vote on the compensation of the NEOs is not binding on the Company, the Board or the compensation committee of the Board (“Compensation Committee”), we value the opinions of our shareholders. Accordingly, the Board and the Compensation Committee will consider the outcome of this advisory vote when considering future compensation policies, procedures and decisions with respect to our NEOs. The Company expects to hold its next “say-on-pay” vote at its 2026 annual meeting of shareholders.

THE BOARD UNANIMOUSLY RECOMMENDS THAT YOU VOTE “FOR” THE SAY-ON-PAY PROPOSAL. Unless otherwise instructed, the persons designated in the enclosed proxy card intend to vote “FOR” the Say-on-Pay Proposal.

PROPOSAL NO. 4 – RE-APPOINTMENT AND REMUNERATION OF AUDITORS

The members of our Audit Committee and our Board believe the re-appointment of Baker Tilly US, LLP (“Baker Tilly”) as our auditor is in the best interests of the Company and our shareholders. Ratification requires the receipt of “FOR” votes constituting a majority of the shares cast by the shareholders who vote in respect of this proposal. Representatives of Baker Tilly are expected to attend the Meeting, will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions.

Principal Audit Fees and Services

Baker Tilly has served as our independent registered public accounting firm since May 13, 2021. The engagement of Baker Tilly was approved by the Audit Committee and the Board.

Aggregate fees billed by our independent auditors, Baker Tilly, for the fiscal years ended December 31, 2025 and December 31, 2024 are detailed in the table below.

Notes:

Pre-approval Policies and Procedures

Our Audit Committee has established a policy of reviewing, in advance, and either approving or not approving, all audit, audit-related, tax and other non-audit services that our auditor provides to us. This policy requires that all services received from our auditor be approved in advance by the Audit Committee. The Audit Committee has delegated pre-approval responsibility to the Chair of the Audit Committee with respect to non-audit related fees and services.

Our Audit Committee has determined that the provision of the services as set out above is compatible with the maintaining of our auditor’s independence in the conduct of their auditing functions.

Audit Committee Report

The material in this report is not “soliciting material,” is not deemed “filed” with the SEC, and is not to be incorporated by reference into any filing by Green Thumb Industries Inc. under the Securities Act of 1933, as amended, or the Exchange Act.

The primary purpose of the Audit Committee is to assist the Company’s Board in fulfilling its responsibilities for oversight of financial, audit and accounting matters. The Audit Committee reviews the financial reports and other financial information provided by the Company to regulatory authorities and its shareholders, as well as reviews the Company’s system of internal controls regarding finance and accounting, including auditing, accounting and financial reporting processes.

The Audit Committee has reviewed and discussed with our management and Baker Tilly US, LLP (“Baker Tilly”), the Company’s independent registered public accounting firm, our audited financial statements and management’s and Baker Tilly’s evaluations of our internal control over financial reporting. Further, the Audit Committee has discussed with Baker Tilly the matters required to be discussed under applicable auditing standards, including Auditing Standard No. 1301. In addition, the Audit Committee discussed with Baker Tilly its independence, and received from Baker Tilly the written disclosures and the letter required by applicable requirements of the Public Company Accounting Oversight Board. Finally, the Audit Committee discussed with Baker Tilly, with and without management present, the scope and results of Baker Tilly’s audit of such financial statements.

Based on these reviews and discussions, the Audit Committee recommended to the Board that such audited financial statements be included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025.

THE BOARD UNANIMOUSLY RECOMMENDS THAT YOU VOTE “FOR” THE RESOLUTION RE-APPOINTING BAKER TILLY AS AUDITORS FOR THE COMPANY AND THE AUTHORIZATION OF THE BOARD TO FIX THE AUDITORS’ REMUNERATION AND TERMS OF ENGAGEMENT. The persons named in the accompanying Proxy Instrument (if named and absent contrary directions) intend to vote the shares represented thereby FOR the resolution re-appointing Baker Tilly as auditors of the Company for the ensuing year and to authorize the directors to fix Baker Tilly’s remuneration and terms of engagement.

PROPOSAL NO. 5 – VOTE TO APPROVE AMENDMENT TO THE COMPANY’S ARTICLES

The Company proposes to amend the Existing Articles to vary the automatic conversion provisions of the Super Voting Shares, as further described below (the “Amended Articles”).

Proposed Amendment to the Articles

As of the date hereof, 201,690 Super Voting Shares are issued and outstanding, all of which are held by “Initial Holders” (as that term is defined in the Existing Articles).

Section 28.1(7)(b) of the Existing Articles provides that each Super Voting Share held by an Initial Holder shall be automatically converted into one Multiple Voting Share if, at any time, the aggregate number of Super Voting Shares held by such Initial Holder and such Initial Holder’s predecessor or transferor, permitted transferees and permitted successors is less than 50% of the Super Voting Shares beneficially owned, directly or indirectly, by such Initial Holder as at June 12, 2018, being the date of completion of the business combination between the Company, VCP23, LLC and GTI Finco Inc. (the “Automatic Conversion Threshold”). Super Voting Shares and Multiple Voting Shares are economically equivalent, except that one Super Voting Share holds 10 times the number of votes at a meeting of shareholders of the Company compared to one Multiple Voting Share.

The proposed Amended Articles will amend the Existing Articles such that the Automatic Conversion Threshold will be changed from 50% to 25% (the “Amendment”). There are no other amendments contemplated in the Amended Articles.

As of the date hereof, Benjamin Kovler, Anthony Georgiadis and Andrew Grossman, all of whom are members of the Company’s management team, are Initial Holders under the Existing Articles, and each such person beneficially owns over 50% of the Super Voting Shares that they initially beneficially owned, directly or indirectly, as of June 12, 2018. (For complete details of the shareholdings of the Initial Holders, see the information set forth under “Security Ownership of Certain Beneficial Owners and Management” below.) The Amendment, if approved, would permit the Initial Holders to effectuate ownership changes in their Super Voting Shares, without their remaining Super Voting Shares being automatically converted into Multiple Voting Shares, provided such Initial Holder continues to hold 25% of the Super Voting Shares originally issued to them.

Both the Audit Committee of the Board and the independent members of the Board have determined that the Amendment is in the best interest of the Company. In connection with its review, the Audit Committee of the Board and the independent members of the Board considered:

Amendment Proposal

At the Meeting, shareholders will be asked to approve a special resolution in the form set out below, subject to such amendments, variations or additions as may be approved at the Meeting, to approve the Amended Articles. If the resolution approving the Amended Articles is approved by the shareholders, it is expected that the Amended Articles will be implemented forthwith.

The text of the resolution to be submitted to shareholders at the Meeting is set out below:

“BE IT RESOLVED as a special resolution that:

Required Vote

You may select “For”, “Against” or “Abstain” with respect to the Amendment. In order to be passed, the special resolution authorizing the Amendment must be approved by (i) not less than 66 2/3% of the votes cast upon such resolution by all shareholders, voting as a single class, present or represented by proxy at the Meeting; and (ii) a simple majority of affirmative votes cast at the Meeting, excluding votes cast by the Initial Holders.

THE INDEPENDENT MEMBERS OF THE BOARD UNANIMOUSLY RECOMMEND THAT YOU VOTE “FOR” THE AMENDMENT. Unless otherwise instructed, the persons designated in the enclosed proxy card intend to vote “FOR” the Amendment.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table sets forth the beneficial ownership of the Company’s Subordinate Voting Shares, Multiple Voting Shares and Super Voting Shares as of April 20, 2026 for (i) each member of the Board of Directors, (ii) each NEO (as defined under “Compensation Discussion and Analysis” below), (iii) each person known to the Company and expected to be the beneficial owner of more than 5% of the Company’s securities and (iv) the members of the Board and the named executive officers of the Company as a group. Beneficial ownership is determined according to the rules of the SEC. Generally, a person has beneficial ownership of a security if the person possesses sole or shared voting or investment power of that security, including any securities that a person has the right to acquire beneficial ownership of within 60 days. Except as indicated, all shares of the Company’s securities are owned directly, and the person or entity listed as the beneficial owner has sole voting and investment power. The address for each director and executive officer is c/o Green Thumb Industries Inc., 325 West Huron Street, Suite 700, Chicago, Illinois 60654.

* Less than 1%
