[PRE 14A] Anteris Technologies Global Corp. Preliminary Proxy Statement

Rhea-AI Filing Summary

Anteris Technologies Global Corp. (Nasdaq AVR) has filed a PRE 14A calling a fully virtual special meeting for 4 Sep 2025.

Shareholders will vote on: (1) ASX’s three-year waiver of Listing Rule 7.1, allowing equity issuances above the current 15 % cap without prior ASX shareholder approval, and (2) authority to adjourn the meeting to gather more proxies if Proposal 1 lacks support.

The board argues the waiver aligns AVR with U.S. peers and provides funding flexibility for the DurAVR THV program, while Nasdaq’s 20 % and change-of-control rules will still govern large deals.

Proposal 1 needs 75 % of votes cast; Proposal 2 needs a simple majority. Illustrative scenarios show potential shareholder dilution from 8 % up to 73 %, depending on deal size and price. Record date is 11 Aug 2025; CDI holders must instruct CDN to vote on their behalf.

The board unanimously recommends voting FOR both proposals.

Insights

Corporate Governance Analyst

TL;DR: Waiver boosts capital flexibility but poses dilution; 75 % hurdle means outcome hinges on broad shareholder backing.

The filing is strategically significant. If approved, AVR can bypass ASX’s 15 % issuance cap for three years, expediting fund-raising for DurAVR. This brings the company in line with U.S. norms yet still constrained by Nasdaq’s 20 % thresholds, limiting extreme dilution unless shareholders consent. The board quantifies dilution risk up to 73.5 %, providing unusual transparency. Requiring 75 % of votes cast is a high bar; coordinated support from major holders (L1 Capital 16.4 %, Sio 8.4 %) is essential. Failure would slow access to equity markets and could impede clinical milestones. Overall impact: positive but contingent on voter turnout.

Buy-side Portfolio Manager

TL;DR: Flexibility aids funding roadmap; dilution risk could pressure valuation—net effect depends on pricing discipline.

From a portfolio view, Proposal 1 lowers execution risk for future offerings, potentially reducing financing overhang. However, illustrative tables show material dilution at lower share prices; investors must weigh near-term capital needs against long-term ownership erosion. Adjournment authority is routine. I classify the filing as neutral overall: benefits offset by dilution uncertainty.

CDI holders may only instruct CDN to vote on their behalf by completing and signing the CDI Voting Instruction Form and are not eligible to electronically vote during the virtual Special Meeting.

Why did I receive a full set of these materials, instead of a notice regarding the Internet availability of proxy materials?

We are using the “Full Set Delivery” method of providing proxy materials to stockholders. Because we have elected to utilize the “Full Set Delivery” option, we are delivering to all stockholders of record paper copies of the Proxy Statement and form of proxy card, as well as providing access to those proxy materials on a publicly accessible website.

To log in, stockholders (or their authorized representatives) will need the control number provided on their proxy card.

The meeting will begin promptly at 5:00 p.m. Central time on September 4, 2025 (being 8:00 a.m. AEST on September 5, 2025). We encourage you to access the meeting prior to the start time.

We recommend that you carefully review the procedures needed to gain admission in advance. A recording of the meeting will be available at www.virtualshareholdermeeting.com for 90 days after the meeting.

Holders of CDIs will be entitled to receive notice of, and to attend as guests (but not vote at) the Special Meeting. CDI holders may only instruct CDN to vote on their behalf by completing and signing the CDI Voting Instruction Form and are not eligible to electronically vote during the virtual Special Meeting. See “How do I vote if I hold CDIs?”

Can I ask questions at the virtual Special Meeting?

No, questions will not be accepted at the virtual Special Meeting.

What if I have technical difficulties or trouble accessing the virtual Special Meeting?

We will have technicians ready to assist you with any technical difficulties you may have accessing the virtual meeting.

TABLE OF CONTENTS

2.
to approve the adjournment of the Special Meeting, if necessary, to solicit additional proxies if there are not sufficient votes in favor of the ASX Waiver Proposal (the “Adjournment Proposal”).

We will also consider other business, if any, that properly comes before the Special Meeting.

What happens if other business not discussed in this Proxy Statement comes before the meeting?

The Company does not know of any business to be presented at the Special Meeting other than the proposals discussed in this Proxy Statement. If other business properly comes before the meeting under our Second Amended and Restated Certificate of Incorporation (the “Charter”), Amended and Restated Bylaws (the “Bylaws”), and rules established by the SEC, the proxies will use their discretion in casting all the votes that they are entitled to cast.

How does the Board recommend that stockholders vote on the proposals?

Our Board recommends that stockholders vote:

• “FOR” the approval of the ASX Waiver Proposal; and

• “FOR” the approval of the Adjournment Proposal.

Who is entitled to vote?

As of the Record Date,        shares of Common Stock were outstanding. Only holders of record of our Common Stock as of the Record Date will be entitled to notice of, and to vote at, the Special Meeting or any adjournment or postponement thereof. Each stockholder is entitled to one vote for each share of our Common Stock held by such stockholder on the Record Date. No cumulative voting rights are authorized. CDI holders may only instruct CDN to vote on their behalf by completing and signing the CDI Voting Instruction Form and are not eligible to electronically vote during the virtual Special Meeting.

What does it mean to be a holder of CDIs?

CDIs are issued by the Company through CDN and traded on the Australian Securities Exchange. If you own CDIs, then you are the beneficial owner of one share of Common Stock for every one CDI that you own. CDN, or its custodian, is considered the stockholder of record for the purposes of voting at the Special Meeting. As the beneficial owner, you have the right to direct CDN, or its custodian, as to how to vote the shares of Common Stock underlying your CDIs. As a beneficial owner, you are invited to attend the Special Meeting. However, because you are not a stockholder, if you personally want to vote the shares of Common Stock underlying your CDIs at the Special Meeting, you must inform CDN via the CDI Voting Instruction Form that you wish to nominate yourself (or another person) to be appointed as CDN’s proxy for the purposes of virtually attending and voting at the Special Meeting.

Under the rules governing CDIs, CDN is not permitted to vote on your behalf on any matter to be considered at the Special Meeting unless you specifically instruct CDN how to vote. We encourage you to communicate your voting instructions to CDN in advance of the Special Meeting to ensure that your vote will be counted by completing the CDI Voting Instruction Form and returning it in accordance with the instructions specified on that form.

How do I vote in advance of the Special Meeting?

If you are a holder of record of shares of Common Stock of the Company, you may direct your vote without attending the Special Meeting by following the instructions on the proxy card to vote via the Internet or by telephone, or by signing, dating, and mailing a proxy card.

If you hold your shares via a broker, bank, or other nominee (i.e., in street name), you may direct your vote without attending the Special Meeting by signing, dating, and mailing your voting instruction card. Internet or telephonic voting may also be available. Please see your voting instruction card provided by your broker, bank, or other nominee for further details.

CDI holders may only instruct CDN to vote on their behalf by completing and signing the CDI Voting Instruction Form. See “How do I vote if I hold CDIs?”

6

TABLE OF CONTENTS

How do I vote during the Special Meeting?

Shares held directly in your name as the stockholder of record may be voted if you are attending the Special Meeting by entering the 15-digit control number found on your proxy card when you log in to the meeting at www.virtualshareholdermeeting.com/AVR2025SM.

Shares held in “street name” through a brokerage account or by a broker, bank, or other nominee may only be voted at the Special Meeting by submitting voting instructions to your bank, broker or other nominee or by presenting a legal proxy, issued in your name from the record holder (your bank, broker or other nominee).

Even if you plan to attend the Special Meeting, we recommend that you vote in advance, as described above under “How do I vote in advance of the Special Meeting?” so that your vote will be counted if you are unable to attend the Special Meeting.

CDI holders are not eligible to vote during the Special Meeting. CDI holders may only instruct CDN to vote on their behalf by completing and signing the CDI Voting Instruction Form.

How do I vote if I hold CDIs?

Each CDI holder is entitled to direct CDN to vote one vote for every one CDI held by such holder on the Record Date. Persons holding CDIs are entitled to receive notice of and to attend the Special Meeting as guests. Holders of CDIs may direct CDN to vote their underlying shares of Common Stock at the Special Meeting by completing and returning the CDI Voting Instruction Form to Computershare, the agent the Company has designated for the collection and processing of voting instructions from the Company’s CDI holders. Votes must be received by Computershare by no later than 5:00 p.m. Central time on September 2, 2025 (being 8:00 a.m. AEST on September 3, 2025) in accordance with the instructions on the CDI Voting Instruction Form.

Can I change my vote or revoke my proxy or CDI Voting Instruction Form?

You may change your vote or revoke your proxy at any time before it is voted at the Special Meeting. If you are a stockholder of record (not including a CDI holder), you may change your vote or revoke your proxy by:

• delivering to the attention of the Secretary a written notice of revocation of your proxy at Toowong Tower, Level 3, Suite 302, 9 Sherwood Road, Toowong QLD 4066, Australia;

• delivering to us an authorized proxy bearing a later date (including a proxy via the Internet or by telephone); or

• attending the Special Meeting and voting electronically, as indicated above under “How do I vote during the Special Meeting?” but note that attendance at the Special Meeting will not, by itself, revoke a proxy.

If your shares are held in the name of a bank, broker, or other nominee, you may change your vote by submitting new voting instructions to your bank, broker, or other nominee. Please note that if your shares are held of record by a bank, broker, or other nominee and you decide to attend and vote at the Special Meeting, your vote at the Special Meeting will not be effective unless you present a legal proxy, issued in your name from the record holder (your bank, broker, or other nominee).

If you are a holder of CDIs and you direct CDN to vote by completing the CDI Voting Instruction Form, you may revoke those instructions by delivering to Computershare a written notice of revocation bearing a later date than the CDI Voting Instruction Form previously sent, which notice must be received by no later than 5:00 p.m. Central time on September 2, 2025 (being 8:00 a.m. AEST on September 3, 2025).

What is a broker non-vote?

Brokers, banks, or other nominees holding shares on behalf of a beneficial owner (other than CDN) may vote those shares in their discretion on certain “routine” matters even if they do not receive timely voting instructions from the beneficial owner. With respect to “non-routine” matters, the broker, bank, or other nominee is not permitted to vote shares for a beneficial owner without timely received voting instructions. Each of the proposals to be voted on at the Special Meeting are non-routine matters. Therefore, if you hold your shares in “street name,” you must instruct your broker how to vote for the proposals in order for your shares to be voted at the Special Meeting.

7

TABLE OF CONTENTS

A broker non-vote occurs when a broker, bank, or other nominee does not vote on a non-routine matter because the beneficial owner of such shares has not provided voting instructions with regard to such matter. The effect of broker non-votes on each of the proposals is described below.

What constitutes a quorum?

The presence at the Special Meeting, either in person or by proxy, of holders of a majority in voting power of the shares of stock issued and outstanding and entitled to vote at the Special Meeting shall constitute a quorum for the transaction of business. Abstentions and broker non-votes will be counted as present for the purpose of determining whether there is a quorum at the Special Meeting. Your shares are counted as being present if you participate virtually at the Special Meeting and cast your vote online during the meeting prior to the closing of the polls by visiting www.virtualshareholdermeeting.com/AVR2025SM, or if you vote by proxy via the Internet, by telephone, or by returning a properly executed and dated proxy card or voting instruction form by mail.

What does it mean if I receive more than one proxy card or CDI Voting Instruction Form?

If you hold your shares or CDIs in more than one account, you will receive one proxy card or CDI Voting Instruction Form for each account (as applicable).

TABLE OF CONTENTS

How will my shares be voted if I return a blank proxy card or a blank CDI Voting Instruction Form?

If you are a holder of record of our Common Stock and you sign and return a proxy card or CDI Voting Instruction Form or otherwise submit a proxy without giving specific voting instructions, your shares will be voted:

• “FOR” the approval of the ASX Waiver Proposal; and

• “FOR” the approval of the Adjournment Proposal.

If you hold your shares in street name via a broker, bank, or other nominee and do not provide the broker, bank, or other nominee with voting instructions (including by signing and returning a blank voting instruction card), your shares:

• will be counted as present for purposes of establishing a quorum; and

• will not be counted in connection with the other proposals or any other non-routine matters that are properly presented at the Special Meeting. For each of these proposals, your shares will be treated as “broker non-votes.”

Our Board knows of no matter to be presented at the Special Meeting other than the proposals identified in this Proxy Statement. If any other matters properly come before the Special Meeting upon which a vote properly may be taken, shares represented by all proxies received by us will be voted with respect thereto as permitted and in accordance with the judgment of the proxy holders.

Who is making this solicitation and who will pay the expenses?

This proxy solicitation is being made on behalf of our Board. The Company will pay the cost of soliciting proxies for the Special Meeting. In addition to solicitation by mail, our employees may solicit proxies personally or by telephone or facsimile, but they will not receive additional compensation for these services. Arrangements may be made with brokerage houses, custodians, nominees, and fiduciaries to send proxy materials to their principals, and we may reimburse them for their expenses.

A list of stockholders entitled to vote at the Special Meeting will be available for inspection by stockholders for any purpose germane to the meeting for 10 business days prior to the Special Meeting, at Anteris Technologies Global Corp., Toowong Tower, Level 3, Suite 302, 9 Sherwood Road, Toowong QLD 4066, Australia between the hours of 9:00 a.m. and 5:00 p.m. AEST. The stockholder list will also be available to stockholders of record for examination during the Special Meeting at www.virtualshareholdermeeting.com/AVR2025SM. You will need the control number included on your proxy card, or voting instruction form, or otherwise provided by your bank, broker, or other nominee.

What is “householding” and how does it affect me?

We have adopted a procedure approved by the SEC called “householding.” Under this procedure, we send only one set of proxy materials to eligible stockholders who share a single address, unless we have received instructions to the contrary from any stockholder at that address. This practice is designed to eliminate duplicate mailings, conserve natural resources, and reduce our printing and mailing costs. Stockholders who participate in householding will continue to receive separate proxy cards.

If your shares are held beneficially and you share an address with another stockholder and receive only one set of proxy materials but would like to request a separate copy of these materials, please contact Broadridge Financial Solutions, Inc., by calling (866) 540-7095 or writing to Broadridge Householding Department, 51 Mercedes Way, Edgewood, New York 11717, and an additional copy of proxy materials will be promptly delivered to you. Similarly, if you receive multiple copies of the proxy materials and would prefer to receive a single copy in the future, you may also contact Broadridge at the above telephone number or address. If you own shares through a bank, broker, or other nominee, you should contact the nominee concerning householding procedures.

How can I find out the results of the voting at the Special Meeting?

We will announce preliminary voting results at the Special Meeting. In accordance with ASX Listing Rule 3.13, we will release the voting results from the Special Meeting by way of an announcement to the ASX as soon as

possible after the conclusion of the Special Meeting. We will also disclose voting results on a Current Report on Form 8-K that we will file with the SEC within four business days after the Special Meeting.

When are stockholder proposals due for the 2025 annual meeting of the stockholders?

Rule 14a-8 Shareholder Proposals. Stockholders who intend to have a proposal considered for inclusion in our proxy materials for presentation at our 2025 Annual Meeting of Stockholders pursuant to Rule 14a-8 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) must submit the proposal to our executive offices at Toowong Tower, Level 3, Suite 302, 9 Sherwood Road, Toowong QLD 4066, Australia in writing within a reasonable time before we begin to print and send our proxy materials. We will announce the date of our 2025 Annual Meeting of Stockholders and the date by which stockholder proposals need to be received by us within a reasonable amount of time before we begin to print and send our proxy materials.

Proposals or Director Nominees. Stockholders intending to present a proposal of business at the 2025 Annual Meeting of Stockholders, but not to include the proposal in our proxy statement, or to nominate a person for election as a director, must comply with the requirements set forth in our Bylaws. Our Bylaws require, among other things, that the stockholder notice must be delivered to or mailed and received by our Secretary at our principal executive offices not less than 90 nor more than 120 calendar days prior to the first anniversary of the date on which we held the preceding year’s annual meeting of stockholders; provided, however, that if the date of the annual meeting is scheduled for a date more than 30 calendar days prior to or more than 30 calendar days after the anniversary of the preceding year’s annual meeting, notice by the stockholder to be timely must be so delivered not later than the close of business on the later of the 90th calendar day prior to such annual meeting and the 10th calendar day following the day on which public disclosure of the date of such meeting is first made. The notice must contain the information required by our Bylaws, a copy of which is available upon request to our Secretary.

SEC rules permit management to vote proxies in its discretion in certain cases if the stockholder does not comply with the above deadlines and, in certain other cases, notwithstanding the stockholder’s compliance with these deadlines.

In addition to satisfying the foregoing requirements under our Bylaws, to comply with the universal proxy rules, stockholders who intend to solicit proxies in support of director nominees other than the Company’s nominees must provide notice that sets forth the additional information required by Rule 14a-19(b) of the Exchange Act.

MATTERS TO BE CONSIDERED AT THE SPECIAL MEETING

PROPOSAL ONE –

THE ASX WAIVER PROPOSAL

Background

ASX Listing Rule 7.1 limits the amount of equity securities that a company listed on the ASX can issue without the approval of its stockholders over any twelve-month period to 15% of the fully-paid ordinary securities that the company had outstanding at the start of that period, subject to certain exceptions (the “15% Limit”).

In order to provide the Company with additional flexibility when evaluating financing options and capital raising transactions, the Company applied to the ASX for the grant of a waiver from ASX Listing Rule 7.1 in order to permit the Company to issue new securities in excess of the 15% Limit without obtaining stockholder approval under ASX Listing Rule 7.1 (the “Waiver”).

Rationale for Seeking the Waiver

While U.S. public companies must comply with the rules imposed by their securities exchanges and their organizational documents, U.S. public companies that are not subject to the ASX Listing Rules are able to offer and sell their securities without the restrictions imposed by the 15% Limit applicable under ASX Listing Rule 7.1. In addition, alternative capital raising structures that are exceptions to ASX Listing Rule 7.1, are uncommon for companies domiciled in the United States to undertake, and the Board believes that limiting itself to such capital raising structures is not in the Company’s or its stockholders’ best interests.

The Company anticipates that additional funds will need to be generated in order to achieve the Company’s long-term goals and complete the clinical development program and proposed commercialization of the DurAVR^® Transcatheter Heart Valve (“THV”) System. To become and remain profitable, the Company has commenced conducting clinical trials and is seeking to obtain regulatory approvals with the aim of commercializing, manufacturing and supplying products, including the DurAVR^® THV System, that generate significant revenue.

Consequently, the Board believes that, due to the Company currently being subject to the 15% Limit under ASX Listing Rule 7.1, the Company operates at a significant disadvantage in being able to raise equity capital as compared to other U.S. public companies, which is not in the best interests of the Company or its stockholders.

Even if stockholders approve the Waiver, the Company will still be subject to the listing rules of the Nasdaq Stock Market LLC (“Nasdaq”), which impose stockholder approval requirements prior to the occurrence of certain issuances of the Company’s securities, including:

• Nasdaq Listing Rule 5635(a), which requires stockholder approval prior to the issuance of Common Stock (or other securities convertible into or exercisable for Common Stock) in connection with the acquisition of the stock or assets of another company, if such securities are not issued in a public offering for cash, and (i) the Common Stock has, or will have upon issuance, voting power equal to or in excess of 20% of the voting power outstanding before the issuance of such securities, or (ii) the number of shares of Common Stock to be issued is or will be equal to or in excess of 20% of the number of shares of Common Stock outstanding before the issuance of such securities;

• Nasdaq Listing Rule 5635(b), which requires stockholder approval prior to an issuance of securities that will result in a “change of control” of the Company. Although Nasdaq has not adopted any rule as to what constitutes a “change of control” for purposes of Rule 5635(b), Nasdaq has previously indicated that the acquisition of, or right to acquire, by a single investor or affiliated investor group, as little as 20% of the Common Stock (or securities convertible into or exercisable for Common Stock) or voting power could constitute a change of control;

• Nasdaq Listing Rule 5635(c), which requires stockholder approval prior to the issuance of securities when an equity compensation arrangement is made or materially amended, pursuant to which Common Stock may be acquired by officers, directors, employees, or consultants, subject to certain exceptions outlined in such rule; and

• Nasdaq Listing Rule 5635(d), which requires stockholder approval prior to the issuance of securities in connection with a transaction, other than a public offering, involving the sale, issuance or potential

TABLE OF CONTENTS

issuance by the Company of Common Stock (or securities convertible into or exercisable for Common Stock), which alone or together with sales by officers, directors or substantial stockholders of the Company, equals 20% or more of the Common Stock or 20% or more of the voting power outstanding before the issuance, in each case, at a price that is less than the “Minimum Price.” The Minimum Price is the lower of (1) the Nasdaq official closing price (as reflected on Nasdaq.com) immediately preceding the signing of the binding agreement for the transaction or (2) the average Nasdaq official closing price of the Common Stock (as reflected on Nasdaq.com) for the five trading days immediately preceding the signing of the binding agreement.

In light of these factors, the Board believes that the stockholders’ approval of the ASX’s grant of the Waiver to the Company is in the best interests of the Company and its stockholders.

As at the date of this Proxy Statement, there is no guarantee that the Company will undertake a capital raising (either in reliance on the Waiver or otherwise), however, given the Company’s growth and capital needs, the Company may elect do so at any time (including in reliance on the Waiver following the Special Meeting, assuming stockholder approval of this Proposal One).

Terms of the Waiver

On August 7, 2025 (AEST), the ASX granted the Waiver, subject to the following terms and conditions:

• the Company remains subject to, and complies with, the Nasdaq listing rules and relevant United States federal and state securities laws for Delaware corporations with respect to the issuance of new securities;

• the grant of the Waiver to the Company must be approved by a special resolution of the Company’s stockholders, which is the stockholder approval sought in this Proposal One;

• the Waiver will remain in force for a period of three years commencing on the date of the Special Meeting (assuming stockholder approval of this proposal);

• the Company must include a statement in or with its full year financial statements that are provided to the ASX that summarizes the Waiver and confirms that the Company remains subject to, and continues to comply with, the requirements of the Nasdaq listing rules and relevant United States federal and state securities laws for Delaware corporations with respect to the issuance of new securities. Prior to publishing this statement, the Company must confirm with ASX that there has been no change to ASX’s policy settings in relation to security holder approval requirements; and

• the Company must immediately advise the ASX if the Company becomes aware of any change to the application of the Nasdaq listing rules or relevant United States federal and state securities laws for Delaware corporations with respect to the issuances of new securities, or that the Company is no longer in compliance with the requirements of the Nasdaq listing rules or the relevant United States federal and state securities laws for Delaware corporations with respect to the issuances of new securities.

Without limiting ASX's right to vary or revoke its decision pursuant to ASX Listing Rule 18.3, the ASX reserves the right to revoke the Waiver if:

• the Company fails to comply with any of the conditions set forth above;

• there are changes to the Nasdaq listing rules concerning the issuance of new securities; or

• there are changes to ASX’s policy settings in relation to security holder approval requirements arising from the current review of those settings or any subsequent review.

TABLE OF CONTENTS

Effect of Proposal One

If Proposal One is approved by the Company’s stockholders, for a period of three years, the Company will not be prohibited by ASX Listing Rule 7.1 from issuing equity securities in excess of the 15% Limit without prior stockholder approval.

If Proposal One is not approved by the Company’s stockholders, the Company will remain subject to ASX Listing Rule 7.1, which requires approval from the Company’s stockholders prior to any issuance of equity securities in excess of the 15% Limit, other than in a transaction structure specifically excepted in ASX Listing Rule 7.2 or if the Company was to seek and obtain a waiver from the ASX to issue shares in excess of the 15% Limit without stockholder approval.

Risk of Economic and Voting Dilution

If Proposal One is approved by the Company’s stockholders, and the Company issues equity securities in excess of the 15% Limit, the voting power of the Company’s existing stockholders may be diluted, as shown in the table below. In addition, there is a risk that:

• the market price for the Company’s Common Stock may be significantly lower on the date of any issuance of the Company’s equity securities than on the date hereof; and

• the Company may issue its equity securities at a price that is a discount to the market price for the Company’s equity securities on the date of issuance or the equity securities may be issued as part of acquisition consideration for an asset or another entity,

each of which would impact the amount of funds raised pursuant to the issuance of equity securities.

The table below sets forth hypothetical equity security issuances by the Company and the corresponding dilutionary effects, assuming that 36,062,370 shares of Common Stock (including in the form of CDIs) are outstanding, which was the number of shares of Common Stock (including in the form of CDIs) outstanding on July 31, 2025, prior to the hypothetical issuance of equity securities by the Company. The scenarios shown in the table are indicative only and do not represent the Company’s intentions or views in respect of the likely size or pricing of any capital raising activities that may be undertaken by the Company should Proposal One be approved by the Company’s stockholders.

PROPOSAL TWO –

THE ADJOURNMENT PROPOSAL

The Proposal

The Board believes that, if the Special Meeting is convened and a quorum is present, but there are insufficient votes to approve the ASX Waiver Proposal, it is in the best interests of the Company and its stockholders to enable the Company to continue to seek to obtain a sufficient number of additional votes to approve such proposal.

The Company is requesting that our stockholders authorize the holder of any proxy solicited by the Board to vote in favor of granting discretionary authority to the proxy holders, and each of them individually, to adjourn the Special Meeting to another time and place, if necessary, to solicit additional proxies in the event there are not sufficient votes to approve the ASX Waiver Proposal. If our stockholders approve this Proposal Two, we could adjourn the Special Meeting, and any adjourned or postponed session of the Special Meeting, to use the additional time to solicit additional proxies, including the solicitation of proxies from our stockholders that have previously voted.

The Company currently does not intend to propose adjournment at the Special Meeting if there are sufficient votes to approve the ASX Waiver Proposal.

Vote Required

The affirmative vote of a majority of shares present in person or represented by proxy and entitled to vote on the matter is required for approval of the Adjournment Proposal. Abstentions will have the same effect as a vote against the Adjournment Proposal.

Recommendation of Our Board of Directors

OUR BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT OUR STOCKHOLDERS VOTE “FOR” THE APPROVAL OF THE ADJOURNMENT PROPOSAL.
