MANAGEMENT INFORMATION AND PROXY CIRCULAR

MANAGEMENT SOLICITATION OF PROXIES

This Management Information and Proxy Circular (“Information Circular”) is furnished to you, as a holder of common shares in the capital of the Company (“Common Shares”), in connection with the solicitation of proxies by management and the Board of Directors (the “Board”) of NioCorp Developments Ltd. (“we,” “us,” “our,” “NioCorp” or the “Company”) for use at the Annual General Meeting of Shareholders of the Company (the “Meeting”) to be held on Thursday, March 20, 2025, at 10:00 a.m. Mountain Daylight Time (“MDT”) at 7000 S. Yosemite Street, Lower Level Conference Room, Centennial, Colorado, 80112 and at any adjournment of the Meeting for the following purposes:

to receive and consider the audited financial statements of the Company for the year ended June 30, 2024, together with the auditor’s report thereon;

to elect seven directors to hold office until the next annual general meeting;

to appoint Deloitte & Touche LLP (“Deloitte”) as auditors of the Company to hold office until the next annual general meeting and to authorize the Board of Directors to fix their remuneration through the Audit Committee (the “appointment of auditors proposal”);

to approve, on a nonbinding, advisory basis, the compensation of our named executive officers (the “say-on-pay proposal”); and

to transact such other business as may properly come before the Meeting or any adjournment or postponement thereof.

For purposes of this Information Circular, management’s solicitation of proxies on matters subject to the vote of the shareholders shall also be deemed to be a solicitation by the Board.

It is anticipated that the Notice of Meeting, this Information Circular, our Annual Report to Shareholders and the accompanying form of proxy (collectively, the “Meeting Materials”) will be first made available to shareholders on or about February 3, 2025. Unless otherwise stated, the information contained in this Information Circular is given as of January 30, 2025.

The principal executive office of the Company is located at 7000 South Yosemite Street, Suite 115, Centennial, Colorado 80112. The registered and records office of the Company is located at 1133 Melville Street, Suite 3500, The Stack, Vancouver, British Columbia V6E 4E5 (ATTN: Blake, Cassels & Graydon LLP).

All references to currency in this Information Circular are in United States dollars, unless otherwise indicated.

Information regarding the proxies being solicited in connection with the Meeting is set out in the section below under the heading “Information about Proxies.”

IMPORTANT NOTICE REGARDING THE AVAILABILITY OF PROXY MATERIALS FOR THE ANNUAL GENERAL MEETING OF SHAREHOLDERS TO BE HELD ON MARCH 20, 2025:

For this Meeting, the Company is utilizing the notice-and-access method of delivery of materials to its registered shareholders and Canadian and United States beneficial shareholders as set out in National Instrument 54-101, Communication with Beneficial Owners of Securities of a Reporting Issuer (“NI 54-101”) and National Instrument 51-102 Continuous Disclosure Obligations and Rule 14a-16 under the United States Securities Exchange Act of 1934, as amended (the “Exchange Act”). The Company is making the Meeting Materials available electronically via the Internet. The Company is mailing to shareholders a notice containing instructions on how to access and review the Meeting Materials and vote online (the “Notice of Internet Availability of Meeting Materials”). You will not receive

a printed copy of the Meeting Materials in the mail unless requested. If you would like a printed copy of the Meeting Materials, follow the instructions for requesting them that are included in the Notice of Internet Availability of Meeting Materials. The Company has elected not to use the procedure known as “stratification” in relation to its use of the notice-and-access rules. Stratification occurs when a reporting issuer using the notice-and-access rules provides a paper copy of proxy-related materials to some, but not all, of its shareholders.

There are two kinds of non-registered, or beneficial, shareholders – those who object to their name being made known to the issuers of securities which they own (called “OBOs” for Objecting Beneficial Owners) and those who do not object to the issuers of the securities they own knowing who they are (called “NOBOs” for Non-Objecting Beneficial Owners). In accordance with NI 54-101, the Company has elected to send the Meeting Materials indirectly to the NOBOs and to the OBOs through their intermediaries. The Company does not intend to pay for intermediaries to forward to OBOs, under NI 54-101, the Meeting Materials, and in the case of an OBO, the OBO will not receive these materials unless the OBO’s intermediary assumes the cost of delivery.

INFORMATION ABOUT PROXIES

Solicitation of Proxies

The Company will conduct its solicitation of proxies and our officers, directors and employees may, without receiving special compensation, contact shareholders by telephone, electronic means or other personal contact. We will not specifically engage employees to solicit proxies. We will pay the expenses of this solicitation; however, we do not reimburse shareholders, nominees or agents (including brokers holding shares on behalf of clients) for their costs of obtaining authorization from their principals to sign proxies. While no arrangements have been made to date, the Company may contract for the solicitation of proxies for the Meeting. Such arrangements would include customary fees which would be borne by the Company.

Appointment of Proxyholder and Return of Proxy

The persons named in the form of proxy for the Meeting attached hereto as Schedule A are officers of the Company and nominees of management. A shareholder has the right to appoint some other person, who need not be a shareholder, to represent such shareholder at the Meeting by inserting that other person’s name in the blank space provided on the form of proxy. If a shareholder appoints one of the persons designated in the accompanying form of proxy as a nominee and does not direct the said nominee to vote “FOR” or “WITHHOLD” with respect to each of the nominees for director listed therein and the appointment of auditors proposal, “FOR,” “AGAINST,” or “ABSTAIN” with respect to the say-on-pay proposal, or where instructions on the form of proxy are uncertain with respect to which an opportunity to specify how the Common Shares registered in the name of such registered shareholder shall be voted is provided, the proxy shall be voted “FOR” with respect to each of the nominees for director listed therein, the appointment of auditors proposal, and the say-on-pay proposal.

In order for a proxy to be valid, it must be:

(a)

signed by the registered shareholder whose name appears thereon or by such registered shareholder’s attorney authorized in writing, or if the registered shareholder is a corporation, by a duly authorized representative on behalf of such corporation; and

(b)

returned in one of the following manners:

(i)

by hand delivery or by mail addressed to Computershare Investor Services Inc., Proxy Dept., 100 University Avenue, 8th Floor, Toronto, Ontario, M5J 2Y1, and received by 10:00 a.m. MDT on March 18, 2025, or no later than 48 hours before the Meeting is reconvened following any adjournment or postponement;

(ii)

by facsimile to Computershare Investor Services Inc. at 1-866-249-7775 (within North America) or 1-416-263-9524 (outside North America) and received by 10:00 a.m. MDT on March 18, 2025, or no later than 48 hours before the Meeting is reconvened following any adjournment or postponement; or

(iii)

by deposit with the chair of the Meeting prior to commencement of the Meeting.

An executed proxy that is returned undated will be deemed to be dated the date of the mailing of the form of proxy by the Company or its agent.

Alternatively, a registered shareholder may vote via the Internet or by telephone by following the instructions included in the Notice of Internet Availability of Meeting Materials, in each case no later than 10:00 a.m. MDT on March 18, 2025, or no later than 48 hours before the Meeting is reconvened following any adjournment or postponement. All instructions for how to vote are listed in the accompanying form of proxy and notes thereto.

Revocation of Proxy

If you are a registered shareholder who has returned a valid proxy, you may revoke your proxy at any time before it is exercised. In addition to revocation in any other manner permitted by law, a registered shareholder who has given a proxy may revoke it by:

(a)

signing a proxy bearing a later date; or

(b)

signing a written notice of revocation in the same manner as the form of proxy is required to be signed as set out in the notes to the proxy.

The later proxy or the notice of revocation must be delivered to the office of the Company’s registrar and transfer agent or to the Company’s principle executive offices at any time up to and including the last business day before the scheduled time of the Meeting or the reconvening of the Meeting following any adjournment, or to the chair of the Meeting on the day of the Meeting or the reconvening of the Meeting following any adjournment.

You may also revoke your proxy by voting via Internet or telephone at a later date than the date of the proxy, or by attending the meeting and voting in person.

If you are a non-registered shareholder (a “Beneficial Shareholder”) who wishes to revoke a VIF (as defined below) or to revoke a waiver of your right to receive Meeting Materials and to give voting instructions, you must give written instructions to your broker, agent, trustee or other intermediary through which you hold your Common Shares in accordance with the applicable procedures and deadlines of your broker, agent, trustee or other intermediary.

Voting of Proxies and Exercise of Discretion by Proxyholders

The persons named in the accompanying form of proxy will vote, withhold, or abstain from voting the Common Shares represented by the proxy in accordance with your instructions, provided your instructions are clear. You may indicate the manner in which the persons named in the form of proxy are to vote on any matter by marking an “X” in the appropriate space. If you have specified a choice on any matter to be acted on at the Meeting, your shares will be voted, withheld, or abstained from voting accordingly. If you do not specify a choice or where you specify more than one choice for any matter to be acted on, your shares will be voted in accordance with management’s recommendations on such matters.

The form of proxy gives the persons named as proxy holders discretionary authority regarding amendments or variations to matters identified therein and any other matter that may properly come before the Meeting. As of the date of this Information Circular, our management is not aware of any such amendment, variation or other matter proposed or likely to come before the Meeting. However, if any such amendment, variation or other matter properly comes before the Meeting, the persons named in the form of proxy intend to vote on such other business in accordance with their judgment.

Voting by Beneficial Shareholders

The information set out in this section is important to many shareholders as a substantial number of shareholders hold their Common Shares through a broker, agent, trustee or other intermediary.

Beneficial Shareholders should note that only proxies deposited by registered shareholders whose names appear on the share register of the Company as of January 27, 2025, the record date for the Meeting, may be recognized and acted upon at the Meeting. If Common Shares are shown on an account statement provided to a Beneficial Shareholder

by a broker, then in almost all cases the name of such Beneficial Shareholder will not appear on the share register of the Company. Such Common Shares will most likely be registered in the name of the broker or an agent of the broker. In Canada, the vast majority of such shares will be registered in the name of “CDS & Co.,” the registration name of CDS Clearing and Depositary Services Inc., and in the United States, the vast majority will be registered in the name of “Cede & Co.,” the registration name of The Depository Trust Company, which entities act as nominees for many brokerage firms. Common Shares held by brokers, agents, trustees or other intermediaries can only be voted by those brokers, agents, trustees or other intermediaries in accordance with instructions received from Beneficial Shareholders. As a result, Beneficial Shareholders should carefully review the voting instructions provided by their intermediary with this Information Circular and ensure they communicate how they would like their Common Shares voted in accordance with those instructions.

Intermediaries will frequently use service companies to forward proxy solicitation information to Beneficial Shareholders. Generally, a Beneficial Shareholder who has not waived the right to receive such information will either:

(a)

be given a form of proxy which (i) has already been signed by the intermediary (typically by a facsimile, stamped signature), (ii) is restricted as to the number of shares beneficially owned by the Beneficial Shareholder, and (iii) must be completed, but not signed, by the Beneficial Shareholder and deposited with Computershare Investor Services Inc.; or

(b)

more typically, be given a voting instruction form (“VIF”), which (i) is not signed by the intermediary, and (ii) when properly completed and signed by the Beneficial Shareholder and returned to the intermediary or its service company, will constitute voting instructions which the intermediary must follow.

VIFs should be completed and returned in accordance with the specific instructions noted on the VIF. The purpose of this procedure is to permit Beneficial Shareholders to direct the voting of the Common Shares which they beneficially own.

Please return your voting instructions as specified in the VIF. Beneficial Shareholders should carefully follow the instructions set out in the VIF, including those regarding when and where the VIF is to be delivered.

Although Beneficial Shareholders may not be recognized directly at the Meeting for the purpose of voting Common Shares registered in the name of their broker, agent, trustee or other intermediary, a Beneficial Shareholder may attend the Meeting as a proxyholder for a shareholder and vote Common Shares in that capacity. Beneficial Shareholders who wish to attend the Meeting or have someone else attend on their behalf and indirectly vote their Common Shares as proxyholder for the registered shareholder should contact their broker, agent, trustee or other intermediary well in advance of the Meeting to determine the steps necessary to permit them to indirectly vote their Common Shares as a proxyholder.

Securities Entitled to Vote

The Company is authorized to issue an unlimited number of Common Shares, of which 44,010,799 Common Shares are issued and outstanding as of January 27, 2025. There is only one class of shares.

The Board has fixed January 27, 2025, as the record date for the purpose of determining the shareholders entitled to receive notice of and vote at the Meeting. Persons who are registered shareholders at the close of business on January 27, 2025, will be entitled to receive notice of, attend, and vote at the Meeting. By ballot, every shareholder and proxyholder will have one vote for each Common Share. Other than with respect to the election of directors, a majority (i.e., at least 50% plus one vote) of the votes cast will be required to pass an ordinary resolution at the Meeting, and at least two-thirds of the votes cast will be required to pass a special resolution at the Meeting. Each of the resolutions that shareholders will be asked to approve at the Meeting, to pass the management proposals set forth in this Information Circular, are ordinary resolutions.

Broker Non-Votes, Abstentions and Quorum

Brokers and other intermediaries, holding shares in street name for their customers, are required to vote the shares in the manner directed by their customers. Under the rules of the New York Stock Exchange, brokers are prohibited from

giving proxies to vote on non-routine matters (including, but not limited to, non-contested director elections) unless the beneficial owner of such shares has given voting instructions on the matter.

The absence of a vote on a matter where the broker has not received written voting instructions from a Beneficial Shareholder is referred to as a “broker non-vote.” Any shares represented at the Meeting but not voted (whether by abstention, broker non-vote or otherwise) will have no impact on any matters to be acted upon at the Meeting.

Under the Articles of the Company, a quorum for the transaction of business at the Meeting is two or more persons present and being, or representing by proxy, 33 1/3% of the outstanding shares entitled to be voted on at the Meeting.

Abstentions will be counted as present for purposes of determining the presence of a quorum at the Meeting but will not be counted as votes cast. Broker non-votes will not be counted as present for purposes of determining the presence of a quorum for purposes at the Meeting and will not be voted. Accordingly, neither abstentions nor broker non-votes will have any effect on the outcome of the votes on the matters to be acted upon at the Meeting.

INTERESTS OF CERTAIN PERSONS IN MATTERS TO BE ACTED UPON

Except as disclosed herein, none of the directors or executive officers of the Company, nor any person who has held such a position since the beginning of the last completed fiscal year of the Company, nor any proposed nominee for election as a director of the Company, nor any associate or affiliate of the foregoing persons, has any substantial or material interest, direct or indirect, by way of beneficial ownership of securities or otherwise, in any matter to be acted on at the Meeting.

PRINCIPAL SHAREHOLDERS

The following table sets forth the beneficial ownership of Common Shares of NioCorp for the following: (1) each person who is known by NioCorp to beneficially own more than 5% of the outstanding shares of NioCorp’s Common Shares; (2) each of the named executive officers (as defined in the “Fiscal 2024 Summary Compensation Table,” below); (3) each of NioCorp’s directors; and (4) all directors and executive officers of NioCorp as a group.

Beneficial ownership of Common Shares in the table below is determined in accordance with the rules of the U.S. Securities and Exchange Commission (the “SEC”) and includes voting or investment power with respect to the Common Shares. Common Shares that may be acquired by an individual or group within 60 days of January 30, 2025, pursuant to the exercise of options to purchase Common Shares (“Options”), the exercise of Common Share purchase warrants (“Warrants”) or the exchange of shares of Class B common stock of Elk Creek Resources Corp (“ECRC”) (formerly known as GX Acquisition Corp. II), are deemed to be outstanding for the purpose of computing the percentage ownership of such individual or group but are not deemed to be outstanding for the purpose of computing the percentage ownership of any other person shown in the table. Percentage of ownership is based on 44,010,799 Common Shares outstanding as of January 30, 2025. Unless otherwise noted in the table below, Options vested at the grant date.

Except as indicated in footnotes to this table, we believe that the shareholders named in this table have sole voting and investment power with respect to all Common Shares shown to be beneficially owned by them, based on information provided to us by such shareholders. Unless otherwise indicated, the address for each director and executive officer listed is: c/o NioCorp Developments Ltd., 7000 South Yosemite Street, Suite 115, Centennial, CO 80112.

Legal Proceedings

No director, nominee or executive officer of the Company is a party adverse to the Company or any of its subsidiaries or has a material interest adverse to the Company or any of its subsidiaries.

During the past ten years, none of the persons serving as executive officers and/or directors of the Company and, with respect to promoters or control persons, for the past five years, none have been the subject matter of any of the legal proceedings that are required to be disclosed pursuant to Item 401(f) of Regulation S-K. Further, no such legal proceedings are believed to be contemplated by governmental authorities against any director or executive officer.

Other than as described below, no proposed director of the Company is or has been, within the past 10 years, a director, CEO or CFO of any company that, while the person was acting in that capacity:

(a)

was subject to an “order,” as that term is defined in Form 51-102F5 Information Circular, that was issued while the proposed director was acting in the capacity as director, CEO or CFO; or

(b)

was subject to an order that was issued after the proposed director ceased to be a director, CEO or CFO and which resulted from an event that occurred while that person was acting in the capacity as director, CEO or CFO.

No proposed director of the Company is or has been, within the past 10 years, a director or executive officer of any 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.

No proposed director of the Company has, within the past 10 years, become 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 the assets of the proposed director.

Voting Procedures for the Election of Directors

Cumulative voting (i.e., a form of voting where shareholders are permitted to cast all of their aggregate votes for a single nominee) will not be permitted. The directors must be elected by an affirmative vote of a plurality of the votes cast, either in person or by proxy, at the Meeting on this matter. Abstentions will not be counted FOR or WITHHOLD with respect to any nominee to the Board.

Majority Voting Policy

On March 17, 2023, the Board adopted a new majority voting policy (the “Majority Voting Policy”). Pursuant to the Majority Voting Policy, the form of proxy for meetings of the shareholders of the Company at which directors are to be elected provides the option of voting in favor, or withholding from voting, for each individual nominee to the Board. If, with respect to any particular nominee, the number of shares withheld from voting exceeds the number of shares voted in favor of the nominee, then the nominee will be considered to have not received the support of the shareholders, and such nominee is required to tender his or her resignation to the Board, to take effect on acceptance by the Board.

The Nominating and Corporate Governance Committee (the “Nominating Committee”) will decide whether to recommend to the Board that the Board accept the resignation of the director. In recommending to the Board whether to request the resignation of the director or not, the Nominating Committee will consider all factors deemed relevant, including without limitation, the qualifications of the director and whether the director’s resignation from the Board would be in the best interest of the Company. In addition, it will consider what, if any, expressed reasons for a withheld vote have been given, the merits of such reasons and the ability to rectify concerns.

Any director who tenders their resignation pursuant to this policy will not participate in the Nominating Committee’s deliberations or recommendation or the Board’s deliberations regarding whether to accept or reject the tendered resignation. However, in the event that each member of the Nominating Committee receives a majority withheld vote in the same election, then the Board will appoint a committee comprised solely of independent directors who did not receive a majority withheld vote in that election to consider each tendered resignation and recommend to the Board whether to accept or reject it.

The Board will take formal action on the Nominating Committee’s recommendation within 90 days following the date of the applicable shareholders’ meeting and will promptly announce its decision via press release. The Board will have the final determination whether to accept the resignation. The Board will accept the director’s resignation absent exceptional circumstances. If the resignation is accepted, subject to any corporate law restrictions, the Board may, in each case in accordance with the Articles:

(a)

fill the vacancy by appointing a director whom the Board considers to merit the confidence of the shareholders; or

(b)

decrease the number of directors comprising the Board.

The Majority Voting Policy applies only in the case of an uncontested director election, meaning the number of nominees for election as directors is equal to the number of directors to be elected.

Management recommends a vote “FOR” each of the nominees for director. Unless otherwise instructed, the proxies given pursuant to this solicitation will be voted “FOR” the nominees listed above.

II – APPOINTMENT OF AUDITORS

Change in Certifying Accountant

The Company was notified on October 9, 2023 by BDO USA, P.C. (“BDO”), the Company’s independent registered public accounting firm, that BDO would decline to stand for re-election at the Meeting, and BDO had indicated its intent to remain as the Company’s independent registered public accounting firm until the completion of BDO’s review of the Company’s financial statements and the filing of the Company’s Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2023. On December 4, 2023, BDO notified the Company that it resigned as the Company’s independent registered public accounting firm, effective immediately. On the recommendation of the Audit Committee of the Board (the “Audit Committee”), the Board accepted BDO’s resignation.

BDO’s audit reports on the Company’s consolidated financial statements as of and for the fiscal years ended June 30, 2023 and 2022 did not contain any adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope or accounting principles, except that each report on the Company’s consolidated financial statements contained an explanatory paragraph regarding the Company’s ability to continue as a going concern based

on the Company’s accumulated deficit, recurring losses from operations, and the Company’s expectation of continuing future losses as of June 30, 2023 and 2022.

During the two fiscal years ended June 30, 2023, and in the subsequent interim period through December 4, 2023, there were no “disagreements” (as defined in Item 304(a)(1)(iv) of Regulation S-K and related instructions) between the Company and BDO on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure, which if not resolved to the satisfaction of BDO, would have caused BDO to make reference to the subject matter of the disagreement in their reports on the Company’s consolidated financial statements for such years.

During the two fiscal years ended June 30, 2023, and in the subsequent interim period through December 4, 2023, there were no “reportable events” (as defined in Item 304(a)(1)(v) of Regulation S-K), except that BDO advised the Company of the existence of material weaknesses in management’s internal control over financial reporting, as previously disclosed in the Company’s Amendment No. 1 on Form 10-K/A to its Annual Report on Form 10-K for the fiscal year ended June 30, 2022, the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2023, the Company’s Quarterly Reports on Form 10-Q for the quarterly periods during fiscal year 2023 and the Company’s Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2023.

After being notified that BDO would not stand for re-election, the Audit Committee began a search process to identify a successor independent registered public accounting firm as soon as practicable. Following the resignation of BDO, on December 4, 2023, the Audit Committee recommended to the Board the appointment of Deloitte as the Company’s new independent registered public accounting firm. On the recommendation of the Audit Committee, the Board appointed Deloitte on December 4, 2023, effective immediately, to serve until the close of the annual general meeting of shareholders of the Company held on January 19, 2024.

As part of its search process for a successor independent registered public accounting firm, the Audit Committee solicited proposals from several major accounting firms and conducted an extensive evaluation process in connection with the selection of the Company’s new independent registered public accounting firm. In selecting Deloitte as the Company’s independent registered public accounting firm, the Audit Committee considered several factors, including:

(a)

the professional qualifications of Deloitte, the lead audit partner, and other key engagement personnel;

(b)

Deloitte’s independence and its processes for maintaining its independence; and

the appropriateness of Deloitte’s fees for audit services.

During the Company’s two fiscal years ended June 30, 2023 and 2022, and the subsequent interim period through December 4, 2023, neither the Company nor anyone acting on its behalf consulted with Deloitte regarding: (i) the application of accounting principles to a specified transaction, either completed or proposed; or the type of audit opinion that might be rendered on the Company’s financial statements, and neither a written report nor oral advice was provided to the Company that Deloitte concluded was an important factor considered by the Company in reaching a decision as to any accounting, auditing or financial reporting issue, or (ii) any matter that was either the subject of a disagreement, as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions, or a “reportable event,” as defined in Item 304(a)(1)(v) of Regulation S-K.

At the annual general meeting of shareholders of the Company held on January 19, 2024, the shareholders approved the appointment of Deloitte as auditors of the Company to hold office until the next annual general meeting of shareholders of the Company or until a successor is appointed and authorized the Board to fix their renumeration through the Audit Committee.

Proposal

The Company has proposed the appointment of Deloitte, as auditors of the Company to hold office until the next annual general meeting of shareholders of the Company or until a successor is appointed. It is proposed that the remuneration to be paid to the auditors be fixed by the Board through the Audit Committee.

The Board, on the recommendation of the Audit Committee, recommends the appointment of Deloitte as our auditors to hold office until the Company’s next annual general meeting of shareholders. The Audit Committee proposes that the Board be authorized to fix the remuneration to be paid to the auditors.

Representatives from Deloitte are expected to be present at the Meeting and they will have the opportunity to make a statement if they desire to do so and will be available to respond to appropriate questions.

Pre-approval Policies

The policy of the Audit Committee has been to pre-approve all audit, audit-related and non-audit services performed by our independent auditors and to subsequently review the actual fees and expenses paid to our independent auditors. Accordingly, the Audit Committee pre-approved all audit, audit-related and non-audit services performed by Deloitte and BDO and subsequently reviewed the actual fees and expenses paid for these services.

Abstentions will not be counted as FOR or WITHHOLD with respect to this matter.

Management recommends a vote “FOR” (i) the appointment of Deloitte as auditors of the Company to hold office until the next annual general meeting and (ii) the authorization of the Board to fix their remuneration through the Audit Committee.

III – ADVISORY VOTE TO APPROVE NAMED EXECUTIVE OFFICER COMPENSATION (“SAY-ON-PAY PROPOSAL”)

As required under the Dodd-Frank Wall Street Reform and Consumer Protection Act and Section 14A of the Exchange Act, the Company is asking shareholders to cast a nonbinding, advisory vote to approve the compensation of its named executive officers, as disclosed pursuant to SEC rules, the executive compensation tables and related compensation disclosures included in this Information Circular. This proposal, commonly known as a “say-on-pay” proposal, gives shareholders the opportunity to express their views about the compensation the Company pays to its named executive officers, as described in this Information Circular. The vote is not intended to address any specific items of named executive officer compensation, but rather to address the Company’s overall approach to the compensation of its named executive officers described in this Information Circular.

The text of the resolution to be approved is as follows:

“BE IT RESOLVED, AS AN ORDINARY RESOLUTION, THAT: on a nonbinding, advisory basis, the compensation of the Company’s named executive officers, as disclosed pursuant to Item 402 of Regulation S-K, including in the compensation tables and related narratives and descriptions of the Management Information and Proxy Circular for the Annual General Meeting of Shareholders held on March 20, 2025, is hereby APPROVED.”

The Board believes that the Company’s executive compensation program is designed appropriately and is working effectively to help ensure that the Company compensates its named executive officers for the achievement of performance goals that will enhance shareholder value. Before you vote, please review the section captioned “Executive Compensation” below, which section describes the Company’s named executive officer pay programs and the rationale behind the decisions made by the Board and the Compensation and Organization Committee of the Board (the “Compensation Committee”).

The Company has designed its executive compensation structure to attract, motivate, and retain executives with the skills required to formulate and implement the Company’s strategic business objectives and deliver on the Company’s commitment to build long-term shareholder value. The Company believes that its executive compensation program is competitive, strongly focused on pay-for-performance principles and appropriately balanced between risk and rewards.

You may vote “FOR” or “AGAINST” the resolution or “ABSTAIN” from voting on the resolution. The result of the say-on-pay proposal will not be binding on the Company or the Board; however, the Board values the views of its shareholders. The Board and the Compensation Committee will review the results of the vote and expect to take them into consideration in addressing future compensation policies and decisions. NioCorp currently holds a say-on-pay vote annually, and expects to hold the next such say-on-pay vote at its next annual general meeting of shareholders.

If no voting specification is made on a properly returned or voted proxy card, the proxies named on the proxy card will vote “FOR” the approval, on a nonbinding, advisory basis, of the compensation of the Company’s named executive officers as disclosed in this Information Circular and described in this say-on-pay proposal.

The Board recommends a vote “FOR” the approval, on a nonbinding, advisory basis, of the compensation of the Company’s named executive officers as disclosed in this Information Circular.

CORPORATE GOVERNANCE

Corporate governance relates to the activities of the Board, the members of which are elected by and are accountable to the shareholders, and takes into account the role of the individual members of management who are appointed by the Board and who are charged with the day-to-day management of the Company. The Board is committed to sound corporate governance practices that are both in the interest of its shareholders and contribute to effective and efficient decision making. National Policy 58-201 Corporate Governance Guidelines (“NP 58-201”) establishes corporate governance guidelines that apply to all Canadian public companies. The Company has reviewed its own corporate governance practices in light of these guidelines. In certain cases, the Company’s practices comply with the guidelines; however, the Board considers some of the guidelines not to be suitable for the Company at its current stage of development, and therefore, these guidelines have not been adopted at this time. The Board will consider the matter

in the future as the Company’s development progresses, and such guidelines may be applicable to the Company’s then-level of development. National Instrument 58-101 (“NI 58-101”) mandates disclosure of corporate governance practices for non-Venture Issuers in Form 58-101F1, which disclosure is set out below. The Company is also required to comply with the provisions of SOX and the applicable rules adopted by the SEC pursuant to SOX, as well as the Nasdaq Listing Rules. Maintaining a high standard of corporate governance is a priority for the Board and the Company’s management as both believe that effective corporate governance will help create and maintain shareholder value in the long term. A description of the Company’s corporate governance practices is set out below.

Director Independence

As of January 30, 2025, the Company’s Board consists of Messrs. Smith, Morris, Beling, Oliver, Kehler, and Maselli and Ms. Guerrero-Mahon. The Company utilizes the definition of “independent” as it is set forth in Nasdaq Listing Rule 5605(a)(2) (“Rule 5605(a)(2)”) and National Instrument 52-110 Audit Committees (“NI 52-110”). Further, the Board considers all relevant facts and circumstances in its determination of independence of all members of the Board (including any relationships). Currently, Messrs. Morris, Beling, Oliver, Kehler, and Maselli and Ms. Guerrero-Mahon are considered independent directors. Ms. Wightman, who served as a director of the Company during fiscal 2024, was previously determined by the Board to be an independent director.

At all times since the Company’s annual general meeting of shareholders held on January 19, 2024, the Board has consisted of a majority of independent directors. NP 58-201 suggests that the board of directors of every listed company should be constituted with a majority of individuals who qualify as “independent” directors under NI 52-110, which provides that a director is independent if he or she has no direct or indirect “material relationship” with such company. “Material relationship” is defined as a relationship that could, in the view of a company’s board of directors, reasonably interfere with the exercise of a director’s independent judgment. Of the proposed nominees for election at the Meeting, one, being Mark A. Smith, is an “insider,” as a management director, and accordingly, is not considered by the Board to be “independent.” The remaining six proposed nominees, being Messrs. Morris, Beling, Oliver, Kehler, and Maselli and Ms. Guerrero-Mahon, are each considered by the Board to be “independent,” within the meaning of NI 52-110. Thus, assuming that all the proposed nominees are elected as directors, the Board will continue to be composed of a majority of independent directors.

The Chair of the Board is Mark A. Smith, who is not independent. Michael J. Morris, who serves as the Company’s Lead Director, is independent.

The Board created the Lead Director role as an integral part of a leadership structure that promotes strong, independent oversight of NioCorp’s management and affairs. The Lead Director, who must be independent, has the following primary responsibilities:

•

working with the Chairman to develop and approve Board agendas and meeting schedules;

•

advising the Chairman as to the quality, quantity, and timeliness of the information sent to the Board;

•

developing agendas for and chairing executive sessions of the Board (in which the independent directors meet without management); and

•

acting as a liaison between the independent directors and the Chairman and CEO.

Michael J. Morris has served as the Lead Director since November 2020.

Following meetings of the Board, the independent directors of the Board may reconvene and hold meetings at which non-independent directors and members of management are not in attendance, in order to facilitate open discussion among the Board’s independent directors.

In assessing Form 58-101F1 and making the foregoing determinations, the circumstances of each director have been examined in relation to a number of factors, including discussions with each director, a review of the résumés of the directors, and the corporate relationships and other directorships held by each of them.

Board Meetings

The Board held a total of six meetings during the fiscal year ended June 30, 2024. None of our incumbent directors attended fewer than 75% of the total number of Board meetings and meetings of the committees on which such director served during the fiscal year ended June 30, 2024. Board members are not required to attend the Company’s annual general meetings of shareholders. All then-serving directors attended the Company’s annual general meeting of shareholders held on January 19, 2024.

The attendance record of each director at full Board meetings and with respect to meetings of any committees of which he/she is a member held during the fiscal year ended June 30, 2024, either in person or by conference telephone, are as follows:

Name of Director			Full Board Meetings (6 total)	Audit Committee (8 total)	Safety and Sustainability Committee (1 total)	Compensation Committee (2 total)	Nominating Committee (1 total)
Mark A. Smith			6	N/A	1	N/A	N/A
Michael J. Morris			6	8	N/A	2	1
David C. Beling			6	N/A	1	2	N/A
Nilsa Guerrero-Mahon			6	8	N/A	2	N/A
Peter Oliver			6	N/A	1	N/A	1
Michael G. Maselli			6	8	N/A	N/A	N/A
Dean C. Kehler			6	N/A	N/A	2	1
Anna C. Wightman⁽¹⁾			3	5	1	N/A	N/A
	(1)	Ms. Wightman no longer served on the Audit Committee or the Safety and Sustainability Committee of the Board (the “Safety and Sustainability Committee”) after January 19, 2024, and was not nominated by the Board to stand for re-election at the annual general meeting of shareholders of the Company held on January 19, 2024.

Corporate Governance Guidelines

The Board has adopted the Corporate Governance Guidelines to assist the Board in the exercise of its responsibilities to the Company and its shareholders. The Corporate Governance Guidelines are intended to serve as a flexible framework, rather than as a set of binding legal obligations, through which the Board may conduct its business and provide oversight. The role of the Board is to oversee the performance of the CEO and other senior management of the Company, and to assure that the best interests of shareholders are being served. The Corporate Governance Guidelines are available on our website at www.niocorp.com.

Position Descriptions

The Board has developed a written position description for the Chairman of the Board and the Lead Director included in the Corporate Governance Guidelines. The primary responsibilities of the Lead Director are summarized above under “—Director Independence.” To date, given the size of the Company and its stage of development, the Board does not believe that a formal written position description for the position of the CEO is required, and that good business practices and the common law provide guidance as to what is expected of the position.

The general duties of the CEO are as set forth in the Smith Agreement (as described under “Employment Agreements” in this Information Circular), which were developed by the Board, in consultation with the CEO, at the time the Smith Agreement was entered into and set forth the expectations of the role and position to be fulfilled by the CEO. Pursuant to the Smith Agreement, the Company (acting through the Board) has the ability to modify such duties as required, but it has not found it necessary to do so.

The charters for each of the Audit Committee, the Compensation Committee, the Nominating Committee and the Safety and Sustainability Committee contain a general description of the roles and tasks required to be performed by the Chair of the relevant committee.

Orientation and Continuing Education

The Board provides ad hoc orientation for new directors. New non-management directors are briefed on the overall role of the Board, its committees and its directors, as well as the Company’s strategic plans, short-, medium-, and long-term corporate objectives, current mineral properties and ongoing exploration programs, business risks and mitigation strategies, Corporate Governance Guidelines and existing Company policies when they become directors. However, there is no formal orientation for new members of the Board, and this is considered to be appropriate, given the Company’s size and current level of operations. If the growth of the Company’s operations and/or increased Board turnover warrants it, the Board would consider implementing a formal orientation process.

The skills and knowledge of the Board as a whole is such that no formal continuing education process is currently deemed required. The Board is comprised of individuals with varying backgrounds, who have, both collectively, and in most cases individually, extensive experience in running and managing public companies in the natural resource sector, and several directors are also directors of other resource companies. Board members are encouraged to communicate with management, auditors and technical consultants to keep themselves current with industry trends and developments and changes in legislation, with management’s assistance. The Company will pay the reasonable costs of attendance by directors at continuing education courses and seminars with respect to corporate governance, directors’ duties and obligations and similar matters. Board members have full access to the Company’s records.

Reference is made to the heading “I – Election of Directors,” under “Particulars of Matters to Be Acted Upon” in this Information Circular, for a description of the principal occupations of the proposed nominees for election as members of the Board.

Board Committees

The Board has established the Audit Committee, the Compensation Committee, the Nominating Committee, and the Safety and Sustainability Committee, each of which operates under a written charter that has been approved by the Board.

Our Board has determined that the members of the Audit Committee and Compensation Committee are independent directors under Rule 5605(a)(2) and NI 52-110, including, in the case of all of the members of our Audit Committee, the independence requirements contemplated by Rule 10A-3 under the Exchange Act. In making such determination, the Board considered the relationships that each director has with our Company and all other facts and circumstances that the Board deemed relevant in determining director independence, including the beneficial ownership of our Common Shares by each director.

Audit Committee and Audit Committee Financial Experts

The Audit Committee is currently comprised of Nilsa Guerrero-Mahon, as Chair, Michael J. Morris, and Michael G. Maselli, all of whom are independent directors. Our Board has determined that each of the three members are audit committee financial experts, as defined by the rules of the SEC. Further, all Audit Committee members are financially literate as defined in NI 52-110 and can read and understand fundamental financial statements in accordance with the Nasdaq Listing Rules. The Audit Committee was established in accordance with Section 3(a)(58)(A) of the Exchange Act. During the fiscal year ended June 30, 2024, the Audit Committee met eight times. A copy of the Audit Committee’s Charter is available on the Company’s website at www.niocorp.com.

The Audit Committee’s general duties and responsibilities are to, among other things:

•

Consider and review the adequacy of the Company’s disclosure controls and procedures and internal control over financial reporting;

•

Consider and review with the independent auditors significant findings during the year, including the status of previous audit recommendations and any audit problems or difficulties encountered in the course of audit work, including any restrictions on the scope of activities or access to required information;

•

Review and discuss with the independent auditors any critical audit matter (“CAM”) addressed in the audit of the Company’s financial statements and the relevant financial statement accounts and disclosures that relate to each CAM;

•

Review and discuss with management and the independent auditors the Company’s earnings and other financial press releases, as well as financial information and earnings guidance provided to analysts and rating agencies;

•

Review the effectiveness of the system for monitoring compliance with laws and regulations;

•

Review and approve in advance all related party transactions and possible conflicts of interest of members of the Board and management;

•

Be directly responsible for the appointment, retention, oversight and termination of the independent auditors and the approval of all auditor compensation, including engagement fees, terms, and services; and

•

Review and discuss with the independent auditors the plans for, and the scope of, the annual audit and other examinations, including the adequacy of staffing and compensation.

The Audit Committee may form and delegate authority to subcommittees consisting of one or more members when appropriate. A more complete description of the duties and responsibilities of the Audit Committee is set out in the Audit Committee’s Charter.

Relevant Education and Experience of Audit Committee Members

The education and experience of each member of the Audit Committee relevant to the performance of his/her responsibilities as an Audit Committee member and, in particular, any education or experience that would provide the member with the following items, are included in the Audit Committee members’ biographies as set forth in “Particulars of Matters to Be Acted Upon – I – Election of Directors,” above:

an understanding of the accounting principles used by the Company to prepare its financial statements;

the ability to assess the general application of such accounting principles in connection with the accounting for estimates, accruals and reserves;

experience preparing, auditing, analyzing or evaluating financial statements that present a breadth and level of complexity of accounting issues that are generally comparable to the breadth and complexity of issues that can reasonably be expected to be raised by the Company’s financial statements or experience actively supervising one or more persons engaged in such activities;

an understanding of internal controls and procedures for financial reporting; and

an understanding of audit committee functions.

Reliance on Certain Exemptions

Since the commencement of the Company’s most recently completed financial year, the Company has not relied on the exemptions in section 2.4 (De Minimis Non-audit Services), 3.2 (Initial Public Offerings), 3.4 (Events Outside Control of Member), 3.5 (Death, Disability or Resignation of Audit Committee Member) of NI 52-110 or an exemption from NI 52-110, in whole or in part, granted by a securities regulator under Part 8 (Exemptions) of NI 52-110.

Reliance on the Exemption in subsection 3.3(2) or section 3.6

Since the commencement of the Company’s most recently completed financial year, the Company has not relied on the exemptions in subsection 3.3(2) (Controlled Companies) or section 3.6 (Temporary Exemption for Limited and Exceptional Circumstances).

Reliance on section 3.8

Since the commencement of the Company’s most recently completed financial year, the Company has not relied upon section 3.8 (Acquisition of Financial Literacy) for any of the Audit Committee members.

Audit Committee Oversight

Since the commencement of the Company’s most recently completed financial year, there has not been a recommendation of the Audit Committee to nominate or compensate an external auditor which was not adopted by the Board.

Audit Committee Report

The Audit Committee oversees the Company’s financial reporting process on behalf of the Board. The Committee has three members, each of whom is “independent” as determined under Rule 10A-3 of the Exchange Act and Rule 5605(a)(2) and applicable Canadian rules and regulations. The Audit Committee operates under a written charter adopted by the Board.

The Audit Committee assists the Board by (1) overseeing the integrity of the Company’s financial reporting and internal control, (2) overseeing the independence and performance of the Company’s independent auditors and (3) providing an avenue of communication between management, the independent auditors and the Board.

In the course of conducting its oversight responsibilities regarding the Company’s audited annual financial statements for the year ended June 30, 2024, the Audit Committee reviewed and discussed the audited annual financial statements for the year ended June 30, 2024, which appear in the Company’s Annual Report to Shareholders, with management and the Company’s independent auditors. The Audit Committee reviewed accounting principles, practices and judgments, as well as the adequacy and clarity of the notes to the financial statements.

The Audit Committee reviewed the independence and performance of the independent auditors who are responsible for expressing an opinion on the conformity of the audited financial statements with accounting principles generally accepted in the United States and has discussed with the independent auditors the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board (“PCAOB”) and the SEC.

The Audit Committee meets with the independent auditors to discuss their audit plans, scope and timing on a regular basis, with or without management present. The Audit Committee has received the written disclosures and the letter from the independent auditors required by applicable requirements of the PCAOB for independent auditor communications with audit committees concerning independence, as may be modified or supplemented, and has discussed with Deloitte & Touche LLP its independence from the Company.

Based on the reviews and discussions referred to above, the Audit Committee recommended to the Board, and the Board approved, that the audited financial statements for the fiscal year ended June 30, 2024, be included in the Company’s Annual Report filed on Form 10-K.

There was one meeting of the Nominating Committee during the fiscal year ended June 30, 2024. A copy of the Nominating Committee’s Charter is available on the Company’s website at www.niocorp.com.

The Nominating Committee may form and delegate authority to subcommittees and may delegate authority to one or more designated members of the Nominating Committee.

Identification and Evaluation of Director Nominees

In accordance with the Corporate Governance Guidelines, directors may be nominated by the Board or by shareholders in accordance with the Articles of the Company. The Nominating Committee will consider recommendations for director nominees made by shareholders and others and make recommendations to the Board in accordance with the policies and principles in the Nominating Committee’ Charter and the Corporate Governance Guidelines. For consideration by the Nominating Committee, the nominating shareholder or other person must provide the Company’s Chief Financial Officer and Corporate Secretary, Neal Shah, at the Company’s principal executive offices, with information about the nominee, including the detailed background of the suggested candidate. While the Nominating Committee has established no minimum qualifications, the Nominating Committee considers, among other factors, the nominee’s judgment, independence, relevant subject matter expertise, integrity, experience with businesses or other organizations of comparable size or industry and any other factors deemed relevant to the current needs of the Board, including those that promote diversity of age, gender, race, ethnicity, experience and background. Given the informal policy as described, the Nominating Committee believes that a formal, written policy and procedure with regard to consideration of director candidates recommended by shareholders is not necessary in order for the Nominating Committee to perform its duties.

The Nominating Committee utilizes a variety of methods for identifying and evaluating nominees for director. The Nominating Committee makes recommendations to the Board concerning the selection criteria to be used in seeking nominees for election to the Board. In the case of newly created directorships or vacancies, the Nominating Committee recommends to the Board candidates for election by the Board based on the skills, qualifications and experience of such candidates and in accordance with the policies and principles in its charter and the criteria described in the Corporate Governance Guidelines. As described above, the Nominating Committee considers properly submitted shareholder nominations for candidates for the Board. In considering director nominees proposed by shareholders, the Nominating Committee reviews the skills, qualifications and experience of the director nominees.

Outside of the participation of Mark A. Smith, the CEO, Dean C. Kehler and Michael G. Maselli on the Board as directors, no shareholder or shareholders holding 5% or more of the Company’s outstanding stock, either individually or in aggregate, has recommended a nominee for election to the Board as of the date of this Information Circular.

Board Diversity

The Board has not adopted a written policy or set targets relating to the identification and nomination of diverse directors or executive officers as it does not believe, at the present time, that it is necessary for the Company to have a written policy. The Board is committed to nominating the best individuals with relevant board and industry experience to fill director roles and executive officer positions. The Board believes that diversity is important to ensure that Board members and senior management provide the necessary range of perspectives, experience and expertise required to achieve the Company’s goals and strategic objectives. The Board recognizes that gender diversity is a significant aspect of diversity and acknowledges the important role that women with appropriate and relevant skills and experience can play in contributing to diversity of perspective in the boardroom and in senior management roles.

The Board reviews the general and specific criteria applicable to candidates to be considered for nomination to the Board. The Board aims to maintain the composition of the Board in a way that provides the best mix of skill and experience to guide the Company’s long-term strategy and ongoing business operations. Accordingly, in searches for new directors or officers, the Board considers the level of gender and cultural representation and diversity within its leadership ranks, and this is just one of several factors used in its search process.

Currently, the Company has one female Board member, representing 14% of the Company’s directors, and no female executive officers.

Assessments

Pursuant to its charter, the Nominating Committee adopts a performance review process for the formal evaluation of Board and Board committee performance on an annual basis. Additionally, the charters of the Audit Committee, Nominating Committee, and Compensation Committee conduct an annual self-evaluation of the performance of the Committee, including its effectiveness and compliance with their respective charters. Pursuant to their charters, the Audit Committee, Nominating Committee, and Compensation Committee shall annually review and reassess the adequacy of their charters and recommend to the Board any improvements to their charters that they consider necessary or valuable. Pursuant to its charter, the Safety and Sustainability Committee reviews and assesses, from time to time, its charter so as to ensure it is effectively carrying out its purpose and submits any proposed revisions to the Board for consideration and approval.

The Board has traditionally monitored, but not formally assessed, its performance or the performance of individual directors or committee members or their contributions. The Compensation Committee has, as part of its charter, the responsibility for evaluating, at least annually, the performance of the CEO and the Chairman of the Board. In the future, the Nominating Committee will consider appropriate processes for evaluations of individual directors and may review the processes adopted by similar sized public natural resource companies in order to assist it in this regard.

Board of Directors Tenure

The Board has not adopted policies imposing an arbitrary term or retirement age limit in connection with individuals nominated for election as directors as it does not believe that such a limit is in the best interests of the Company at this time. While term limits facilitate Board refreshment, they can also result in the loss of experience and expertise

that is critical to the effective operation of the Board. Longer tenured directors can provide valuable insight into the Company and its operations. To ensure that the Board continues to evolve and benefit from fresh perspectives and ideas, the Nominating Committee evaluates the qualifications and contributions of each incumbent director before recommending the nomination of such director for an additional term. The Nominating Committee reviews and recommends to the Board, as necessary, retirement policies for directors.

Ethical Business Conduct

The Board expects management to operate the business of the Company in a manner that enhances shareholder value and is consistent with the highest level of integrity. Management is expected to execute the Company’s business plan and to meet performance goals and objectives according to the highest ethical standards.

In addition, directors and senior officers are bound by the provisions of the Company’s Articles and the Business Corporations Act (British Columbia) (the “BCBCA”), which set forth how any conflicts of interest are to be dealt with. In particular, any director who has a material interest in a particular transaction is required to disclose such interest and to refrain from voting with respect to the approval of any such transaction.

Insider Trading Policy

We have insider trading policies and procedures, as described below, applicable to our directors, officers, and employees, and have implemented processes for the Company, that we believe are reasonably designed to promote compliance with insider trading laws, rules, and regulations, and the Nasdaq listing standards.

The Board has adopted an insider trading policy (the “Insider Trading Policy”) to help ensure, among other things: (i) that persons to whom the policy applies understand their obligations to preserve the confidentiality of “Material Nonpublic Information” (as defined in the Insider Trading Policy); (ii) strict compliance by all insiders with all requirements relating to the reporting of insider trading and with respect to trading when in possession of “Material Nonpublic Information”; and (iii) that individuals subject to scheduled and unscheduled blackout periods adhere to the restrictions on trading as set out in the Insider Trading Policy. A copy of our Insider Trading Policy was filed as Exhibit 19.1 to our Annual Report on Form 10-K for the fiscal year ended June 30, 2024.

Code of Business Conduct and Ethics

Our Board has adopted a written Code of Business Conduct and Ethics applicable to our employees, officers and directors, including those officers responsible for financial reporting. The Code of Business Conduct and Ethics is available on our website at www.niocorp.com. If the Board amends the Code of Business Conduct and Ethics or grants a waiver, including an implicit waiver, from the Code of Business Conduct and Ethics, the Company will disclose the information on its internet website. The waiver information will remain on the website for at least 12 months after the initial disclosure of such waiver. Given the current size of the Company workforce, and the lack of significant operations, the Board monitors compliance through periodic discussions with executive management.

Board Role in Risk Oversight

Our Board is responsible for overseeing the Company’s management of risk. The Board strives to effectively oversee the Company’s enterprise-wide risk management in a way that balances managing risks with enhancing the long-term value of the Company for the benefit of the shareholders. The Board understands that its focus on effective risk oversight is critical to setting the Company’s tone and culture towards effective risk management. To administer its oversight function, the Board seeks to understand the Company’s risk philosophy by having discussions with management to establish a mutual understanding of the Company’s overall appetite for risk. Our Board maintains an active dialogue with management about existing risk management processes and how management identifies, assesses and manages the Company’s most significant risk exposures. Our Board expects frequent updates from management about the Company’s most significant risks so as to enable it to evaluate whether management is responding appropriately.

Our Board relies on each of its committees to help oversee the risk management responsibilities relating to the functions performed by such committees. Our Audit Committee periodically discusses with management the

Company’s major financial risk exposures and the steps management has taken to monitor and control such exposures, including the Company’s risk assessment and risk management policies. Our Compensation Committee helps the Board to identify the Company’s exposure to any risks potentially created by our compensation programs and practices. Each of these committees is required to make regular reports of its actions and any recommendations to the Board, including recommendations to assist the Board with its overall risk oversight function.

Board Leadership Structure

The Board has reviewed the Company’s current Board leadership structure in light of the composition of the Board, the Company’s size, the nature of the Company’s business, the regulatory framework under which the Company operates, the Company’s shareholder base, the Company’s peer group and other relevant factors. Considering these factors, the Board has determined not to have a separate CEO and Chairman of the Board and to have a separate Lead Director who is independent. The Chairman of the Board is a non-executive position. The Board has determined that this structure is currently the most appropriate Board leadership structure for the Company. The Board noted the following factors in reaching its determination:

•

The Board acts efficiently and effectively under its current structure.

•

The structure of the same individual holding the positions of CEO and Chairman of the Board, with a separate, independent Lead Director, puts the Company in the best position to efficiently handle major issues facing the Company on a day-to-day and long-term basis, while ensuring that the Board is in the best position to have an independent director identify key risks and developments facing the Company and to have those risks and developments brought promptly to the Board’s attention.

•

This structure eliminates the potential for confusion and duplication of efforts at the highest executive level

•

Companies within the Company’s peer group utilize similar Board structures.

Assumptions used in the calculation of these amounts are described in Note 11 in the Company’s consolidated financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2024. These Options were fully vested on the grant date and generally remain exercisable until three years after the grant date.
	(2)	Ms. Wightman served as a member of the Board until January 19, 2024, and did not receive a grant of Options during the 2024 fiscal year.

For the fiscal year ended June 30, 2024, the directors of the Company did not receive any cash fees for serving on the Board. The directors of the Company have no standard compensation arrangements, or any other arrangements, with the Company, except as herein disclosed. Option grants are determined by the Compensation Committee on a

discretionary basis each year. Executive officers of the Company who also act as directors of the Company do not receive any additional compensation for services rendered in such capacity. See “Fiscal 2024 Summary Compensation Table” below.

The aggregate number of Option awards outstanding at the end of fiscal year 2024 for each non-employee director who served during fiscal 2024 was as follows: Mr. Beling, 117,500 Options; Mr. Morris, 157,500 Options; Ms. Guerrero-Mahon, 150,000 Options; Mr. Oliver, 140,000 Options; Mr. Kehler, 50,000 Options; and Mr. Maselli, 50,000 Options. As of June 30, 2024, all the above Options were 100% vested.

Communications with Directors

We have a formal process for shareholder communications with the Board included in the Corporate Governance Guidelines to ensure that the views of shareholders are heard by the Board or individual directors, as applicable, and that appropriate responses are provided to shareholders in a timely manner. We believe our responsiveness to shareholder communications to the Board has been good. As outlined in the Corporate Governance Guidelines, a shareholder may submit any written communication to the Board, any individual director or the independent directors as group to us at our corporate offices, to the attention of Neal Shah, Chief Financial Officer and Corporate Secretary or via email to corpsecretary@niocorp.com by indicating in the “ATTN:” line of the envelope or the subject line of the email, as applicable, whether the communication is direct to the Board, an individual director or the independent directors as a group. The Chief Financial Officer and Corporate Secretary routinely filters communications that are solicitations, complaints, unrelated to the Company or the Company’s business, inappropriate or determined to pose a possible security risk to the addressee.

Narrative Disclosure to Summary Compensation Table

Compensation Governance

The Compensation Committee determines the amount of compensation for the Company’s executives, which is designed to reflect the need to provide incentives and compensation for the time and effort expended by the executives while taking into account the financial and other resources of the Company. The Compensation Committee has the authority to engage and compensate, at the expense of the Company, any outside advisor that it determines to be necessary to permit it to carry out its duties (including compensation consultants and advisers), and generally utilized information provided by Insperity PEO Services LP (“Insperity”), the Company’s Professional Employer Organization, in February 2023, to assess employee salaries relative to industry and market peers and engaged Bedford Resources Inc. (“Bedford”) in November 2023 to provide competitive data in executive compensation. The Company has assessed the independence of both Insperity and Bedford and has found no conflicts of interest raised by their work.

Compensation Program Design

The Board, in conjunction with the Compensation Committee, determines compensation and rewards to senior management on the basis of individual and corporate performance, both in the short term and the long term, while at the same time being mindful of the responsibility that the Company has to its shareholders. In general, the Compensation Committee considers that its compensation program should be relatively simple in concept, given the current stage of the Company’s development, and that its focus should be balanced between reasonable current compensation and longer-term compensation tied to performance of the Company as a whole.

The Compensation Committee has not established a formal set of benchmarks or performance criteria to be met by the Company’s named executive officers; rather, the members of the Compensation Committee use the information provided by Insperity and Bedford, and their own subjective assessments of the level of success of the Company to determine, collectively, whether or not the named executive officers are successfully achieving the Company’s business plan and strategy and the degree to which they have performed in that regard. The Compensation Committee has not established any set or formal formula for determining named executive officer compensation, either as to the amount thereof or the specific mix of compensation elements, and compensation (and adjustments from time to time) is set through informal discussions at the Compensation Committee level.

Key Elements of Named Executive Officer Compensation

Base Salaries

The members of the Compensation Committee use their own experience and familiarity with the industry, and consider the factors described above, to determine what they believe to be reasonable base salaries for our named executive officers. The base salaries of the named executive officers are set at levels which are considered by the members of the Compensation Committee to be competitive, thereby enabling the Company to compete for and retain executives critical to the long-term success of the Company. Initially, base salaries (or, for Mr. Smith, base consulting fees) are set through negotiation when executive officers join the Company (with direct input from the Compensation Committee) and are subsequently reviewed each fiscal year to determine if adjustments are required.

Bonus Compensation

The Board has discretion, where deemed appropriate and financially affordable for the Company, to grant a cash bonus to a named executive officer based on the performance of both the individual named executive officer and the Company. No cash bonuses were approved or paid for the named executive officers for fiscal year 2024.

Option-Based Awards

The incentive portion of each named executive officer’s compensation package consists primarily of Options awarded under the NioCorp Developments Ltd. Long-Term Incentive Plan, as amended (the “2017 Amended Long-Term

Incentive Plan”). Share ownership opportunities through the grant of Options are provided to align the interests of senior management of the Company with the longer-term interests of the shareholders of the Company.

The 2017 Amended Long-Term Incentive Plan is administered by the Compensation Committee, and is intended to advance the interests of the Company through the motivation, attraction and retention of officers and other key employees, directors and consultants of the Company and affiliates of the Company and to secure for the Company and its shareholders the benefits inherent in the ownership of Common Shares of the Company by officers and other key employees, directors and consultants of the Company and affiliates of the Company. Grants of Options under the 2017 Amended Long-Term Incentive Plan are proposed and recommended by the CEO and reviewed by the Compensation Committee, or are proposed by the Compensation Committee. The Compensation Committee can approve, modify, or reject any proposed grants, in whole or in part. In general, the allocation of available Options among the eligible participants in the 2017 Amended Long-Term Incentive Plan is on an ad hoc basis, and there is no set formula for allocating available Options, nor is there any fixed benchmark or performance criteria to be achieved in order to receive an award of or vest in Options.

The Compensation Committee does not consider the accounting value of any such Option grants in determining the number of Options to award to any individual, as any such “value” is an accounting measure that is not relevant to incentivizing the individual. The timing of the grants of Options is determined by the Compensation Committee, and there is no regular interval for the awarding of Option grants. In general, a higher level of responsibility will result in a larger grant of Options. Because the number of Options available is limited, in general, the Compensation Committee aims to have individuals at what it subjectively considers to be the same levels of responsibility holding equivalent numbers of Options, with additional grants being allocated for individuals who the Compensation Committee believes are in a position to more directly affect the success of the Company through their efforts.

The Compensation Committee looks at the overall number of Options held by an individual (plus the exercise prices and remaining terms of existing Options and whether any previously granted Options have expired out of the money or were exercised) and takes such information into consideration when reviewing proposed new grants. After considering the CEO’s recommendations, if any, and the foregoing factors, the resulting proposed Option grant is then submitted to the Board for final approval.

During the fiscal year ended June 30, 2024, the Compensation Committee approved all recommendations for the grant of Options proposed by management, and the named executive officers were granted the following number of Options effective February 15, 2024, each with an exercise price per share of $2.99 per share: Mr. Smith, 375,000 Options; Mr. Honan, 250,000 Options; and Mr. Shah, 250,000 Options. These Options were fully vested and exercisable on the grant date and generally remain exercisable until five years after the grant date.

On March 28, 2024, the Board approved a modification to Options previously issued on March 27, 2023, with dual strike prices of $6.95 and C$9.52, under which the option to exercise in C$ was removed. No other terms or conditions were amended by the Board.

Employment Agreements and Severance Arrangements

The Company and KMSmith, LLC (“KMSmith”), an entity controlled by Mark A. Smith, entered into a Consulting Agreement effective September 23, 2013 (as amended, the “Smith Agreement”). On August 31, 2020, the Company, KMSmith and 76 Resources, Inc., an entity controlled by Mr. Smith, entered into a Contract Assignment and Novation Agreement, pursuant to which KMSmith assigned all of its rights under the Smith Agreement to 76 Resources, Inc. and 76 Resources, Inc. assumed all of KMSmith’s obligations under the Smith Agreement by novation. On August 1, 2021, the Company, 76 Resources, Inc. and 76 Resources, LLC, an entity controlled by Mr. Smith, entered into a Contract Assignment and Novation Agreement, pursuant to which 76 Resources, Inc. assigned all of its rights under the Smith Agreement to 76 Resources, LLC and 76 Resources, LLC assumed all of 76 Resources, Inc.’s obligations under the Smith Agreement by novation. Under the terms of the Smith Agreement, 76 Resources, LLC (as ultimate successor in interest to KMSmith), through Mr. Smith, performs the duties and responsibilities of the CEO of the Company and related services, for an indefinite term at a base rate of $325,000 per year, generally payable in equal monthly installments of $27,083. Any bonuses and incentive payments are payable at the discretion of the Board. Mr. Smith is eligible to receive Options under the 2017 Amended Long-Term Incentive Plan, as determined by the Board.

The Company may terminate the Smith Agreement at any time without notice or payment if (1) 76 Resources, LLC commits a material breach of the Smith Agreement (subject to a cure period in certain circumstances), (2) Mr. Smith dies or becomes permanently disabled, or (3) certain other “for cause” scenarios occur (as further described in the Smith Agreement). In the event the Smith Agreement is terminated by the Company for any other reason or if 76 Resources, LLC terminates the Smith Agreement on the occurrence of a Triggering Event, the Company shall pay 76 Resources, LLC a lump sum termination fee equal to the base fee in effect at the termination date as well as the average of any annual bonuses or other cash incentive payments for two calendar years immediately preceding the year the termination occurs. A “Triggering Event” is defined as: a substantial change in the nature of services to be performed by 76 Resources, LLC; a material breach by the Company of the Smith Agreement that is not remedied within 30 days of notice; the cessation of the Company as a going concern; the failure of the Company to pay a material amount due pursuant to the Smith Agreement within 30 days of the due date; or a material reduction in base fee or any other form of compensation payable by the Company to 76 Resources, LLC, except where all senior executives or consultants of the Company are subject to relatively similar reductions in such values. 76 Resources, LLC may terminate the Smith Agreement for a reason other than a Triggering Event on 90 days’ written notice and, should the Company immediately accept such termination notice, it shall pay 76 Resources, LLC the sum of $69,904. Should a change of control of the Company occur (as that term is defined in the Smith Agreement) and, within one year, either a Triggering Event occurs and 76 Resources, LLC terminates the Smith Agreement or 76 Resources, LLC’s engagement is terminated by the Company under circumstances that would give rise to a termination payment in the absence of a change of control, then 76 Resources, LLC shall be entitled to receive an amount equal to the base fee in effect at the termination date as well as the average of any annual bonuses or other cash payments for two calendar years immediately preceding the year the termination occurs. In the event 76 Resources, LLC is entitled to a termination payment with respect to a change of control, any Options previously granted to Mr. Smith shall become fully vested and shall remain exercisable for the original term of grant despite a termination of the services of 76 Resources, LLC. Termination payments under the Smith Agreement are generally contingent on a release of claims by 76 Resources, LLC. The Smith Agreement also includes customary confidentiality and six-month employee non-solicitation provisions.

If the Smith Agreement had been terminated by the Company for any reason other than as set out in the Smith Agreement, if 76 Resources, LLC terminated the Smith Agreement on the occurrence of a Triggering Event, or had a change of control of the Company occurred and within one year, either a Triggering Event occurred and 76 Resources, LLC terminated the Smith Agreement or 76 Resources, LLC’s engagement was terminated by the Company without the occurrence of a Triggering Event, for any reason other than as set out in the Smith Agreement, effective as of June 30, 2024, 76 Resources, LLC (as ultimate successor in interest to KMSmith) would have been entitled to a payment of $375,000.

As previously disclosed, on September 25, 2022, in connection with our entry into the Business Combination Agreement, Messrs. Shah and Honan (the “Covered Officers”) entered into employment agreements with a United States affiliate (the “U.S. Affiliate”) of the Company (the “Employment Agreements”). The Employment Agreements became effective as of the Closing, and will continue until either the Covered Officer or the U.S. Affiliate terminates the Covered Officer’s employment for any reason. Pursuant to the Employment Agreements, Mr. Shah continues to serve as Chief Financial Officer of the Company, and Mr. Honan continues to serve as the COO of the Company and serves as President of the U.S. Affiliate.

The Employment Agreement for Mr. Shah provides for an initial annual base salary of $220,000 per year, and Mr. Honan’s Employment Agreement provides for an initial annual base salary of $260,000 per year. The annual base salary rates for the Covered Officers will be reviewed at least annually for potential increases. The base salary rates of Messrs. Shah and Honan were increased in fiscal 2023 to $250,000 for Mr. Shah and $280,000 for Mr. Honan. The Employment Agreements also provide each of the Covered Officers with eligibility to participate in (1) any annual cash bonus plan and/or any long-term incentive compensation plan as may be established by the U.S. Affiliate or its affiliates, and (2) any employee benefit plan, program, or policy of the U.S. Affiliate or its affiliates as may be in effect for senior executives of the U.S. Affiliate or its affiliates generally. The Employment Agreements also include the following additional features: (1) severance benefits upon certain qualifying terminations of employment, consisting of: (a) for a qualifying termination of the Covered Officer’s employment by the U.S. Affiliate without Cause (as such term is defined in the Employment Agreements) that does not occur within two years after a Change in Control of the U.S. Affiliate (as defined in the Employment Agreements), certain accrued obligations, plus 12 months of salary continuation, and (b) for a qualifying termination of the Covered Officer’s employment by the U.S. Affiliate without Cause or by the Covered Officer for Good Reason (as such term is defined in the Employment

Agreements) that occurs within two years after a Change in Control (a “Change in Control Termination”), certain accrued obligations, and a lump sum cash amount equal to two times the Covered Officer’s annual base salary as in effect at the time of such termination; and (2) a requirement that each Covered Executive execute a customary release of claims in favor of the U.S. Affiliate to receive severance compensation. In connection with the Covered Officers entering into the Employment Agreements each Covered Officer also entered into a restrictive covenant agreement (a “Restrictive Covenant Agreement”). The Restrictive Covenant Agreements include customary restrictive covenants, including non-competition and non-solicitation obligations that remain in effect both during the employment term and for one year following termination of the Covered Officer’s employment other than a Change in Control Termination (in which case the period will be two years following such Change in Control Termination), as well as other customary restrictive covenants, such as confidentiality provisions.

Stock Options Under the 2017 Amended Long-Term Incentive Plan

In accordance with the 2017 Amended Long-Term Incentive Plan, the Company granted Options to its named executive officers during the Company’s 2024 fiscal year; no other equity-based awards were granted to the named executive officers during the 2024 fiscal year.

The following table sets forth the outstanding equity awards for each named executive officer at June 30, 2024. The Company has not granted full value stock-based awards to any of its named executive officers.

Retirement Plan Benefits

Messrs. Honan and Shah are each eligible to participate in the Company’s 401(k) savings plan, which is designed to reward continued employment with the Company and assist participants with financial preparation for retirement.

Termination and Change of Control Benefits

Except as described above, the Company has not entered into any plans or arrangements in respect of remuneration received or that may be received by the named executive officers in respect of compensating such officers or directors in the event of a change of control, termination of employment (as a result of resignation, retirement, change of control, etc.) or a change in responsibilities following a change of control. Options are generally subject to clawback

provisions, and provide for post-employment exercise periods, pursuant to the terms of such awards and the 2017 Amended Long-Term Incentive Plan.

Generally, the aggregate number of Common Shares reserved for issuance to participants under the 2017 Amended Long-Term Incentive Plan, together with all other security-based compensation arrangements of the Company may not exceed 10% of the issued and outstanding Common Shares from time to time, and the Common Shares reserved for issuance upon settlement of share units shall not exceed 5% of the issued and outstanding Common Shares from time to time. Common Shares subject to any grant (or any portion thereof) that are issued upon exercise or settlement, forfeited, surrendered, cancelled, unearned, or otherwise terminated will again be available for grant under the 2017 Amended Long-Term Incentive Plan.

(3)

As of the date of this Information Circular there are: (i) 3,063,000 outstanding securities awarded under the 2017 Amended Long-Term Incentive Plan representing 6.96% of the Company’s currently issued and outstanding Common Shares; and (ii) 1,338,079 remaining securities available for grant representing 3.04% of the Company’s currently issued and outstanding Common Shares.

Description of the 2017 Amended Long-Term Incentive Plan

On January 19, 2024, NioCorp’s shareholders approved the adoption of certain amendments to the 2017 Amended Long-Term Incentive Plan. Under the 2017 Amended Long-Term Incentive Plan, the Board may in its discretion from time-to-time grant stock options, share units (in the form of restricted share units (“RSUs”) and performance share units (“PSUs”) and dividend equivalents to non-employee directors, employees and certain other service providers (as further described in the 2017 Amended Long-Term Incentive Plan) of the Company and affiliated entities selected by the Board. Subject to adjustment as provided in the 2017 Amended Long-Term Incentive Plan, the aggregate number of Common Shares that may be reserved for issuance to participants under the 2017 Amended Long-Term Incentive Plan, together with all other security-based compensation arrangements of the Company, may not exceed 10% of the issued and outstanding Common Shares from time to time, and the Common Shares reserved for issuance upon settlement of share units shall not exceed 5% of the issued and outstanding Common Shares from time to time. Further, the aggregate number of Common Shares reserved for issuance to any one participant under the 2017 Amended Long-Term Incentive Plan, together with all other security-based compensation arrangements of the Company, must not exceed 5% of the then issued and outstanding Common Shares (on a non-diluted basis). The maximum number of Common Shares (1) issued to insiders (for purposes of the Toronto Stock Exchange Company Manual) within any one-year period and (2) issuable to insiders at any time, under the 2017 Amended Long-Term Incentive Plan, or when combined with the Company’s other security-based compensation arrangements, will not exceed 10% of the number of the then issued and outstanding Common Shares.

Exchange Controls

There are no governmental laws, decrees, or regulations in Canada that restrict the export or import of capital, including foreign exchange controls, or that affect the remittance of dividends, interest or other payments to non-resident holders of the securities of NioCorp, other than Canadian withholding tax. See “Certain Canadian Federal Income Tax Considerations for U.S. Residents” below.

Certain Canadian Federal Income Tax Considerations for U.S. Residents

The following generally summarizes certain Canadian federal income tax consequences generally applicable under the Income Tax Act (Canada) and the regulations enacted thereunder (collectively, the “Canadian Tax Act”) and the Canada-United States Tax Convention (1980) (the “Convention”) to the holding and disposition of Common Shares.

Comment is restricted to holders of Common Shares each of whom, at all material times for the purposes of the Canadian Tax Act and the Convention, (i) is resident solely in the United States for tax purposes, (ii) is a “qualifying person” under and entitled to the benefits of the Convention, (iii) holds all Common Shares as capital property, (iv) deals at arm’s length with and is not affiliated with the Company, (v) does not and is not deemed to use or hold any Common Shares in a business carried on in Canada, (vi) is not an insurer that carries on business in Canada and elsewhere, (vii) is not an “authorized foreign bank” (as defined in the Canadian Tax Act), and (viii) has not entered into a “derivative forward agreement” (as defined in the Canadian Tax Act) with respect to the Common Shares (each such holder, a “U.S. Resident Holder”).

Certain U.S.-resident entities that are fiscally transparent for United States federal income tax purposes (including limited liability companies) may not in all circumstances be entitled to the benefits of the Convention. Members of or holders of an interest in such an entity that holds Common Shares should consult their own tax advisers regarding the extent, if any, to which the benefits of the Convention will apply to the entity in respect of its Common Shares.

Generally, a U.S. Resident Holder’s Common Shares will be considered to be capital property of such holder provided that the U.S. Resident Holder is not a trader or dealer in securities, did not acquire, hold, or dispose of the Common Shares in one or more transactions considered to be an adventure or concern in the nature of trade (i.e. speculation), and does not hold the Common Shares in the course of carrying on a business.

This summary is based on the current provisions of the Canadian Tax Act and the Convention in effect as of the date prior to the date hereof, all specific proposals to amend the Canadian Tax Act and Convention publicly announced by or on behalf of the Minister of Finance (Canada) prior to the date hereof, and the current published administrative policies and assessing practices of the Canada Revenue Agency (the “CRA”). It is assumed that all such amendments will be enacted as currently proposed, and that there will be no other material change to any applicable law or administrative policy or assessing practice, whether by way of judicial, legislative or governmental decision or action, although no assurance can be given in these respects. This summary is not exhaustive of all possible Canadian federal income tax considerations. Except as otherwise expressly provided, this summary does not take into account any provincial, territorial, or foreign tax considerations, which may differ materially from those set out herein.

This summary is of a general nature only, is not exhaustive of all possible Canadian federal income tax considerations, and is not intended to be and should not be construed as legal or tax advice to any particular U.S. Resident Holder. The tax consequences of acquiring, holding and disposing of Common Shares will vary according to the U.S. Resident Holder’s particular circumstances. U.S. Resident Holders are urged to consult their own tax advisers for advice with respect to their particular circumstances. The discussion below is qualified accordingly.

A U.S. Resident Holder will not be subject to tax under the Canadian Tax Act in respect of any capital gain realized on a disposition or deemed disposition of a Common Share unless the Common Share is “taxable Canadian property” of the U.S. Resident Holder for the purposes of the Canadian Tax Act at the time of disposition and the U.S. Resident Holder is not entitled to an exemption under the Convention. In addition, capital losses arising on a disposition or deemed disposition of a Common Share will not be recognized under the Canadian Tax Act, unless the Common Share constitutes “taxable Canadian property” (as defined in the Canadian Tax Act) at the time of disposition and the U.S. Resident Holder is not entitled to relief under the Convention.

Generally, a U.S. Resident Holder’s Common Shares will not constitute “taxable Canadian property” of such holder at a particular time at which the Common Shares are listed on a “designated stock exchange” (which currently includes the Nasdaq) unless, at any time during the 60-month period that ends at the particular time both of the following conditions are concurrently met:

(i)

25% or more of the issued shares of any class of the capital stock of NioCorp were owned by or belonged to one or any combination of:

the U.S. Resident Holder,

persons with whom the U.S. Resident Holder did not deal at arm’s length, and

partnerships in which the U.S. Resident Holder or a person referred to in clause (b) holds a membership interest directly or indirectly through one or more partnerships, and

(ii)

more than 50% of the fair market value of the Common Shares was derived directly or indirectly from, one or any combination of, real or immovable property situated in Canada, “Canadian resource properties” (as defined in the Canadian Tax Act), “timber resource properties” (as defined in the Canadian Tax Act), or options in respect of, or interests in any of the foregoing, whether or not the property exists.

Notwithstanding the foregoing, Common Shares may also be deemed to be “taxable Canadian property” in certain circumstances set out in the Canadian Tax Act.

A U.S. Resident Holder to whom the Company pays or credits or is deemed to pay or credit a dividend on such holder’s Common Shares will be subject to Canadian withholding tax, and the Company will be required to withhold the tax from the dividend and remit it to the CRA for the holder’s account. The rate of withholding tax under the Canadian Tax Act is 25% of the gross amount of the dividend, but should generally be reduced under the Convention to 15% (or, if the U.S. Resident Holder is a company which is the beneficial owner of at least 10% of the voting stock of the Company, 5%) of the gross amount of the dividend. For this purpose, a company that is a resident of the United States for purposes of the Canadian Tax Act and the Convention and is entitled to the benefits of the Convention shall be considered to own the voting stock of NioCorp owned by an entity that is considered fiscally transparent under the laws of the United States and that is not a resident of Canada, in proportion to such company’s ownership interest in that entity.

PAY VERSUS PERFORMANCE

The following Pay Versus Performance table (“PVP Table”) provides information about compensation for this Information Circular’s named executive officers, as well as our named executive officers from our Management Information and Proxy Circular for the annual general meetings of shareholders of the Company held on December 15, 2022 and January 19, 2024 (each of fiscal years 2022, 2023, and 2024, a “Covered Year”) as required by the pay versus performance rules (“PVP”) adopted by the SEC in August 2022. We refer to all of the named executive officers covered in the PVP Table below, collectively, as the “PVP NEOs”. The PVP Table also provides information about the results for certain measures of performance during those same Covered Years. In reviewing this information, there are a few important things we believe you should consider:

•

The information in columns (b) and (d) of the PVP Table comes directly from this year’s Summary Compensation Table (or the Summary Compensation Tables for the two prior fiscal years), without adjustment, calculated in substantially the same manner as required under SEC rules;

•

As required by the SEC’s PVP rules, we describe the information in columns (c) and (e) of the PVP Table as “compensation actually paid” (or “CAP”) to the applicable PVP NEOs. However, these CAP amounts do not necessarily reflect the final compensation that our NEOs actually earned or walked away with for their service in the Covered Years, respectively; and

•

As required by the SEC’s PVP rules, we provide information in the PVP Table below about our absolute total shareholder return (“TSR”) results and our U.S. generally accepted accounting principles net income results during the Covered Years.

Pay Versus Performance Table

The following table sets forth information concerning the compensation of our principal executive officer, or “PEO,” and, on an average basis, the compensation of our other named executive officers, or “Non-PEO NEOs,” for each of the fiscal years ended June 30, 2024, 2023, and 2022, as such compensation relates to our financial performance for each such fiscal year.

Mark A. Smith was our PEO for the full year for each of the Covered Years. Our non-PEO NEOs for fiscal year 2024 and 2023 were Scott Honan and Neal Shah. Our Non-PEO NEOs for fiscal year 2022 were Scott Honan, Neal Shah, and Jim Sims.

(1)

For each Covered Year, in determining both the CAP for our PEO and the average CAP for our Non-PEO NEOs for purposes of this PVP Table, we deducted from or added back to the total amount of compensation reported in column (b) and column (d) for such Covered Year the following amounts:

Item and Value Added (Deducted) (1)	2024
For Mr. Smith:
- SCT “Stock Awards” column value	—
- SCT “Option Awards” column value	($641,250)
+ Covered Year-end fair value of outstanding unvested equity awards granted in Covered Year	—

+ vesting date fair value of equity awards granted and vested in Covered Year	641,250

- prior year-end fair value of equity awards granted in prior years and forfeited in Covered Year	—
+ includable dividends/earnings on equity awards during Covered Year	—

For Non-PEO NEOs (Average):
- SCT “Stock Awards” column value	—
- SCT “Option Awards” column value	($427,500)
+ Covered Year-end fair value of outstanding unvested equity awards granted in Covered Year	—

+ vesting date fair value of equity awards granted and vested in Covered Year	427,500

- prior year-end fair value of equity awards granted in prior years and forfeited in Covered Year	—
+ includable dividends/earnings on equity awards during Covered Year	—

(2)

For each Covered Year, our TSR was calculated based on the yearly percentage change in our cumulative TSR on our Common Shares, measured as the quotient of (a) the sum of (i) the cumulative amount of dividends for a period beginning with our closing price on the Nasdaq on June 30, 2021 through and including the last day of the fiscal year covered (each one-, two-, or three-year period, the “Measurement Period”), assuming dividend reinvestment, plus (ii) the difference between our closing share price at the end versus the beginning of the Measurement Period, divided by (b) our closing share price at the beginning of the Measurement Period. Each of these yearly percentage changes was then applied to a deemed fixed investment of $100 at the beginning of each Measurement Period to produce the Covered Year-end values of such investment as of the end of fiscal years 2024, 2023 and 2022, as applicable. Because Covered Years are presented in the table in

reverse chronical order (from top to bottom), the table should be read from bottom to top for purposes of understanding cumulative returns over time.

Net loss attributable to the Company decreased significantly during fiscal 2024, as the net loss for fiscal 2023 included costs associated with the Transactions, as defined herein. CAP for our PEO and the average CAP for our Non-PEO NEOs during the same fiscal year increased, reflecting the impact of the non-cash fair value of Options issued during fiscal 2024. Net loss attributable to the Company increased significantly during fiscal year 2023, reflecting costs associated with the Transactions, while CAP for our PEO and the average CAP for our Non-PEO NEOs increased slightly for the same fiscal year.

Because we are not a production stage mining company, we did not have any revenue from continuing operations during the periods presented. As described in more detail above in the section “Compensation Program Design,” we currently utilize subjective assessments of executive performance, and we have not historically focused on net loss as a performance measure for our executive compensation programs. TSR declined across all three fiscal years and CAP for our PEO and the average CAP for our Non-PEO NEOs increased.

The following chart provides, across the Covered Years, descriptions of the relationships between the CAP for the PEO and the average CAP for our Non-PEO NEOs (in each case as set forth in the PVP Table above) and our TSR.

PERFORMANCE GRAPH

The following graph compares total cumulative shareholder return for $100 invested in Common Shares from July 1, 2019 to June 30, 2024, with cumulative total returns for the S&P/TSX Composite Index and S&P/TSX Mining Index:

Overall, the Company’s cumulative return for the five-year period ended below the range of returns for the two selected indices. As an exploration stage company, executive officer compensation has not historically been adjusted to reflect share performance trends. Compensation to executive officers remained flat from 2013 through February 2023, except for increases supported by additional job responsibilities and/or job promotions. Effective September 1, 2019, the Board approved a 10% base rate increase for all NioCorp employees and effective April 1, 2023, the Compensation Committee approved a base rate average increase of 12% for all NioCorp employees.

CERTAIN RELATIONSHIPS AND RELATED PERSON TRANSACTIONS

Related Person Transactions

The following sets forth certain information regarding transactions between the Company (and its subsidiaries) and its officers, directors and significant shareholders. There have been no other transactions since the end of the Company’s most recently completed fiscal year and there are no currently proposed transactions in which the Company was or is to be a participant and the amount involved exceeds $120,000, and in which any related person (for purposes of Item 404 of Regulation S-K) had or will have a direct or indirect material interest.

Loan Transactions:

Mr. Smith is our Chief Executive Officer, President, Executive Chairman, and Director. On January 16, 2017, the Company and Mr. Smith entered into a credit agreement (the “Smith Credit Agreement”) pursuant to which Mr. Smith agreed to make available to the Company a credit facility of initially up to $2,000,000. On January 17, 2020, the Company entered into an amending agreement to the Smith Credit Agreement, increasing the limit of the credit

facility to $2,500,000 from the previous limit of $2,000,000. On April 3, 2020, the Smith Credit Agreement was amended to increase the limit of the credit facility to $3,000,000 and on June 10, 2020, the Smith Credit Agreement was amended to increase the limit of the credit facility to $3,500,000. In addition, on June 10, 2020, the maturity date for the Smith Credit Agreement was extended to December 15, 2020. On December 14, 2020, the maturity date for the Smith Credit Agreement was extended to December 15, 2021. On December 13, 2021, the maturity date for the Smith Credit Agreement was extended to June 30, 2022. On June 29, 2022, the maturity date for the Smith Credit Agreement was extended to June 30, 2023. On February 28, 2023, the Smith Credit Agreement was amended to increase the borrowing limit to $4,000,000 from the previous limit of $3,500,000. The Company subsequently drew down $1,130,000, leaving an available balance under the Smith Credit Agreement of $52,000.

The largest aggregate amount of principal outstanding under the Smith Credit Agreement during the year ended June 30, 2023, was $3,130,000. Principal repayments of $3,130,000 were made under the Smith Credit Agreement during the year ended June 30, 2023. In addition, interest payments of $183,343 were paid under the Smith Credit Agreement during the year ended June 30, 2023, and $0 of interest remained payable as of June 30, 2023. As of June 30, 2023, all principal and accrued interest outstanding under the Smith Credit Agreement had been repaid and the Smith Credit Agreement expired on June 30, 2023. Accounts payable and accrued liabilities as of June 30, 2024, includes $28,250 of origination fees payable under the Smith Credit Agreement.

On September 11, 2024, the Company and Mr. Smith entered into a Loan Agreement (the “Smith Loan Agreement”) pursuant to which Mr. Smith agreed to make available to the Company a non-revolving, multiple draw credit facility of up to $2,000,000 (the “Loan”). The Loan is non-revolving and amounts paid back under the terms of the Smith Loan Agreement do not again become available for drawdowns at the request of the Company.

The Company will pay interest to Mr. Smith on amounts outstanding under the Loan and on any overdue interest at a rate equal to 10% per annum, calculated monthly in arrears, through to the date of repayment of the Loan. Mr. Smith will also receive an establishment fee equal to 2.5% of the amount of any drawdown payable at the time of the drawdown as consideration of the advancement of such drawdown. Any outstanding balance on the Loan, including accrued interest, shall be immediately due and payable by the Company on the earlier of the date of expiration of the Smith Loan Agreement on June 30, 2025, and the occurrence of an event of default thereunder, (the “Due Date”). The Company can repay the Loan at any time without notice and without penalty, but any amount of principal or interest repaid by the Company prior to the Due Date will be subject to an early payment fee of 2.5% of the value of any such payment. Amounts outstanding under the Smith Loan Agreement are secured by all of the Company’s assets pursuant to a general security agreement between the Company and Mr. Smith, dated September 11, 2024.

As of January 30, 2024, no principal or interest remained outstanding under the Loan. The largest aggregate amount of principal outstanding under the Smith Loan Agreement during the period ended January 30, 2025, was $504,000. During the period ended January 30, 2025, the Company repaid $4,200 of interest and $50,400 of principal outstanding under the Loan, and $41,000 related to origination fees payable.

Related Person Transactions Entered into in Connection with the Transactions

On March 17, 2023 (the “Closing Date”), we consummated the transactions contemplated by the previously-announced Business Combination Agreement, dated as of September 25, 2022 (the “Business Combination Agreement”), among NioCorp, GXII and Big Red Merger Sub Ltd. The transactions contemplated by the Business Combination Agreement, including the Reverse Stock Split, are referred to, collectively, as the “Transactions.” After consideration of GXII expenses incurred in connection with the Transactions, the Company acquired net cash of approximately $2.2 million and assumed net liabilities of approximately $0.4 million. We also assumed Private Warrant liabilities and the Earnout Shares liability, which were initially recorded at their non-cash fair market value of approximately $3.0 million and approximately $13.2 million, respectively. The Company incurred expenses related to the Transactions of approximately $6.8 million, all of which were recorded as other operating expenses.

In connection with the Closing, GXII as the surviving entity of the mergers that occurred on the Closing Date as part of the Transactions, changed its name to Elk Creek Resources Corp. and became an indirect, majority-owned subsidiary of NioCorp, with the pre-combination public shareholders of GXII receiving Common Shares based on a fixed exchange ratio of 11.1829212 (or 1.11829212 after giving effect to the Reverse Stock Split) (the “Exchange Ratio”) Common Shares for each Class A common share of GXII held and not redeemed, and the GXII founders

receiving shares of Class B common stock of ECRC based on the Exchange Ratio. Pursuant to the Business Combination Agreement, the Sponsor Support Agreement, dated as of September 25, 2022 (as amended, supplemented or otherwise modified, the “Sponsor Support Agreement”), by and among GXII, NioCorp, the Sponsor and certain other stockholders of GXII, and the Exchange Agreement, dated as of March 17, 2023 (as amended, supplemented or otherwise modified, the “Exchange Agreement”), by and among NioCorp, ECRC and the Sponsor, after the Closing, the GXII founders have the right to exchange such shares of Class B common stock of ECRC for Common Shares on a one-for-one basis, subject to certain equitable adjustments, under certain conditions. Of the issued and outstanding shares of Class B common stock of ECRC: (a) 4,565,808 shares (the “Vested Shares”) are exchangeable at any time, and from time to time, until the tenth anniversary of the Closing Date; (b) 1,695,798 shares (the “Tranche I Earnout Shares”) are not exchangeable until the volume-weighted average price of the Common Shares on the principal securities exchange for the Common Shares as reported by Bloomberg (“VWAP”) equals or exceeds approximately $12.00 per share for 20 of any 30 consecutive trading days during the period from the Closing through, and including, the tenth anniversary of the Closing Date (such period, the “Earnout Share Period”) on any stock exchange on which the Common Shares are then trading; and (c) 1,695,798 shares (the “Tranche II Earnout Shares”) are not exchangeable until the VWAP of the Common Shares equals or exceeds approximately $15.00 per share for 20 of any 30 consecutive trading days during the Earnout Share Period on any stock exchange on which the Common Shares are then trading. All of the shares of Class B common stock of ECRC were issued to GX Sponsor II LLC (the “Sponsor”) in respect of shares of Class B common stock of GXII that were originally issued to the Sponsor for $25,000 in the aggregate. In connection with the Closing, the Sponsor distributed all of the outstanding shares of Class B common stock of ECRC to its members, including Messrs. Maselli and Kehler, for no additional consideration, and such members joined the Sponsor Support Agreement and the Exchange Agreement, as parties thereto.

In connection with the Closing, pursuant to the Business Combination Agreement, the Company assumed the Warrant Agreement, dated as of March 17, 2021 (the “GXII Warrant Agreement”), by and between GXII and Continental Stock Transfer & Trust Company (“CST”), as warrant agent, and each share purchase warrant of GXII thereunder (the “GXII Warrants”) that was issued and outstanding immediately prior to the Closing Date was converted into one Common Share purchase warrant (the “NioCorp Assumed Warrants”) pursuant to the GXII Warrant Agreement, as amended by an assignment, assumption and amendment agreement, dated the Closing Date (the GXII Warrant Agreement, as so amended, the “NioCorp Assumed Warrant Agreement”), among NioCorp, GXII, CST, as existing warrant agent, and Computershare Inc. and its affiliate Computershare Trust Company, N.A., together as successor warrant agent. In connection with the Closing, NioCorp issued (a) 9,999,959 public NioCorp Assumed Warrants (the “Public Warrants”) in respect of the GXII Warrants that were publicly traded prior to the Closing and (b) 5,666,667 NioCorp Assumed Warrants (the “Private Warrants”) to the Sponsor in respect of an equal number of GXII Warrants that it held prior to the Closing, which Private Warrants were subsequently distributed by the Sponsor to its members, including Messrs. Maselli and Kehler, in connection with the Closing for no additional consideration. The Sponsor acquired the GXII Warrants in respect of which the Private Warrants were issued in a private placement that occurred simultaneously with the closing of the initial public offering of GXII at a purchase price of $1.50 per GXII Warrant.

Both the Public Warrants and the Private Warrants are subject to the terms of the NioCorp Assumed Warrant Agreement and are identical, with certain exceptions applicable to the Private Warrants for so long as such Private Warrants are held by the Sponsor, its members, or their respective affiliates and other permitted transferees. In accordance with the NioCorp Assumed Warrant Agreement, any Private Warrants issued to the Sponsor that are not held by the Sponsor, its members, or their respective affiliates and other permitted transferees, are treated as Public Warrants.

Pursuant to the Business Combination Agreement, at the Closing, NioCorp, ECRC, the Sponsor, the pre-Closing directors and officers of NioCorp and the other parties thereto, including Messrs. Maselli and Kehler (collectively, the “RRA Shareholders”), entered into the Amended and Restated Registration Rights Agreement, dated March 17, 2023 (the “Registration Rights and Lockup Agreement”), pursuant to which, among other things, NioCorp became obligated to file a shelf registration statement to register the resale of (i) outstanding Common Shares, (ii) Common Shares exchangeable for the shares of Class B common stock of ECRC, (iii) Private Warrants and (iv) Common Shares issuable upon exercise of the NioCorp Assumed Warrants, in each case, held by the RRA Shareholders immediately after the Closing. The Registration Rights and Lockup Agreement also provides the RRA Shareholders with certain “demand” and “piggy-back” registration rights, subject to certain requirements and customary conditions, and

provides for certain “lock-up” restrictions on transfer by the RRA Shareholders of such securities held by them after the Closing.

The shares of Class B common stock of ECRC and Private Warrants beneficially owned by Messrs. Maselli and Kehler, as disclosed under “Principal Shareholders” above, have an aggregate market value of approximately $2.7 million and $0.2 million, respectively, based on the closing price of the Common Shares of $1.85 and the closing price of the Public Warrants of $0.1125 on Nasdaq on January 27, 2025, the record date for the Meeting.

Effective immediately upon the Closing, the Board increased the size of the Board to nine members and appointed each of Messrs. Maselli and Kehler to the Board. Messrs. Maselli and Kehler served on the board of directors of GXII prior to the Closing. Pursuant to the Business Combination Agreement, the Company was required to cause two directors identified by GXII to become directors of the Company as of Closing, and the Board appointed Messrs. Maselli and Kehler to the Board pursuant to such requirement.

Review, Approval or Ratification of Related Person Transactions

Other than as described below, the Company does not currently have in place any specific policy or procedure in respect of the review, approval or ratification of any transaction required to be reported under Item 404(a) of Regulation S-K. Sections 147-153 of the BCBCA set out rules and procedures applicable to all British Columbia corporations, pursuant to which a director presented with a resolution in respect of any matter (including an equity issuance) in respect of which he/she has an interest must disclose that interest in writing to the corporation’s board of directors prior to the approval of such matter. This procedure ensures that each equity issuance to a director or officer of the Company is approved by all directors of the Company not involved in such sale. All loan transactions from directors and officers are typically subject to review and approval by the Board prior to acceptance and are documented in the meeting minutes or resolutions related to same. Under its charter, the Audit Committee is responsible for reviewing and approving any related party transaction in advance of such transaction, unless the Chief Financial Officer or General Counsel determines that it is not practicable to wait until the next Audit Committee meeting, in which case the related party transaction will be submitted to the Chair of the Audit Committee, who will have delegated authority to act between Audit Committee meetings.

SHAREHOLDER PROPOSALS

Under the Exchange Act, the deadline for submitting shareholder proposals for inclusion in the management information and proxy circular for an annual general meeting of the Company is calculated in accordance with Rule 14a-8(e) of Regulation 14A under the Exchange Act. If the proposal is submitted for a regularly scheduled annual general meeting, the proposal must be received at the Company’s principal executive offices not less than 120 calendar days before the anniversary date of the Company’s management information and proxy circular released to the Company’s shareholders in connection with the previous year’s annual general meeting. However, if the Company did not hold an annual general meeting the previous year, or if the date of the current year’s annual general meeting has been changed by more than 30 days from the date of the previous year’s meeting, then the deadline is a reasonable time before the Company begins to print and mail its proxy materials. Accordingly, unless the date of the next annual general meeting is changed by more than 30 days from the date of this year’s meeting the deadline for submitting shareholder proposals for inclusion in the management information and proxy circular for the next annual general meeting of the Company will be October 6, 2025.

The deadline for submitting shareholder proposals, other than director nominations, for the next annual general meeting of shareholders of the Company, but not for inclusion in the management information and proxy circular, is December 20, 2025. If a shareholder proposal, other than a director nomination, is not submitted to the Company by December 20, 2025, the Company may still grant discretionary proxy authority to vote on such shareholder proposal in accordance with Rule 14a-4(c)(1) of Regulation 14A under the Exchange Act.

Pursuant to Section 188(1)(c) of the BCBCA, the Company is required to include shareholder nominees for director in the management information and proxy circular for an annual general meeting of shareholders if the shareholder director nomination is received by the Company at its principal executive offices no later than the close of business on the date that is at least three months prior to the anniversary date of the Company's last annual general meeting of shareholders, which deadline will not change, even if the date of the annual general meeting changes by more than 30 calendar days from the anniversary date of the Company's last annual general meeting of shareholders. Therefore, the deadline for shareholder director nominations for inclusion in the management information and proxy circular for the Company's next annual general meeting of shareholders is December 19, 2025.

In addition, there are (i) certain requirements relating to shareholder proposals contained in the BCBCA; and (ii) certain requirements relating to the nomination of directors contained in the Articles of the Company. A shareholder wishing to make a proposal for consideration at an annual general meeting of the Company or wishing to nominate a person to act as a director of the Company should ensure they follow the applicable procedures set forth in Section 188 of the BCBCA and the Articles of the Company.

Under the Company’s advance notice policy, adopted by the shareholders of the Company on December 15, 2014, nominations of persons for election to the Board at any annual general meeting of the shareholders must be received by the Corporate Secretary of the Company not less than 30 days or more than 65 days prior to the date of such meeting; provided, however, that in the event that the annual general meeting of shareholders is to be held on a date

that is less than 50 days after the date on which the first public announcement of the date of such meeting was made (the “Meeting Notice Date”), such shareholder’s notice must be so received not later than the close of business on the 10th day following the Meeting Notice Date.

In addition, to comply with the universal proxy rules, shareholders who intend to solicit proxies in support of director nominees for election at the next annual general meeting of shareholders other than the Company's nominees must provide notice that sets forth the information required by Rule 14a-19 under the Exchange Act, which notice must be postmarked or transmitted electronically to the Company at its principal executive offices no later than 60 calendar days prior to the first anniversary of the Meeting, which date is January 19, 2026. If the date of the next annual general meeting of shareholders is changed by more than 30 calendar days from the first anniversary of the Meeting, then any such notice must be provided by the later of 60 calendar days prior to the date of the next annual general meeting of shareholders or the 10th calendar day following the day on which public announcement of the date of the next annual general meeting of shareholders is first made.

DISSENTERS’ RIGHTS OF APPRAISAL

No action is proposed herein for which the laws of British Columbia or the Articles of the Company provide a right of a shareholder to dissent and obtain appraisal of or payment for such shareholder’s Common Shares.

MULTIPLE SHAREHOLDERS SHARING THE SAME ADDRESS

The regulations regarding the delivery of copies of proxy materials and annual reports to shareholders permit the Company and brokerage firms to send one Notice of Internet Availability of Meeting Materials to multiple shareholders who share the same address under certain circumstances. Shareholders who hold their shares through a broker may have consented to reducing the number of copies of materials delivered to their address. In the event that a shareholder wishes to revoke such a consent previously provided to a broker, the shareholder must contact the broker to revoke the consent. In any event, if a shareholder wishes to receive a separate Notice of Internet Availability of Meeting Materials or other materials for the Meeting or future annual meetings, the shareholder may receive copies by contacting the Corporate Secretary at 7000 South Yosemite Street, Suite 115, Centennial, CO 80112, or by calling (855) 264-6267. Shareholders receiving multiple copies of these documents at the same address can request delivery of a single copy of these documents by contacting the Company in the same manner. Persons holding shares through a broker can request a single copy by contacting the broker.
