PROXY STATEMENT FOR SPECIAL MEETING OF STOCKHOLDERS
TO BE HELD ON SEPTEMBER 7, 2023

The Board of Directors (the “Board”) of Applied Optoelectronics, Inc. (the “Company”) is soliciting your proxy for the Special Meeting of Stockholders to be held on September 7, 2023, or any adjournment or postponement thereof, for the purposes set forth in the accompanying Notice of Special Meeting of Stockholders. This Proxy Statement and related materials are first being mailed to stockholders beginning on or about July 28, 2023. References in this Proxy Statement to the “Company,” “we,” “our,” “us” and “Applied Optoelectronics” are to Applied Optoelectronics, Inc. and its consolidated subsidiaries, and references to the “Special Meeting” are to the Special Meeting of Stockholders.

SOLICITATION AND VOTING

Record Date

Only stockholders of record at the close of business on July 19, 2023 will be entitled to notice of and to vote at the meeting and any adjournment thereof. As of this record date there were 31,785,027 shares of common stock outstanding and entitled to vote.

Quorum

A majority of the shares of common stock issued and outstanding as of the record date must be represented at the Special Meeting, either in person or by proxy, to constitute a quorum for the transaction of business at the meeting. Your shares will be counted towards the quorum if you submit a valid proxy (or one is submitted on your behalf by your broker or bank) or if you vote in person at the meeting. In addition, shares present in person, but not voting, shares for which we receive signed proxies, but for which holders have abstained from voting, and shares represented by proxies returned by a bank, broker, or other nominee holding shares will each be counted as present for purposes of determining the presence of a quorum.

Vote Required to Adopt Proposals

Each share of our common stock outstanding on the record date is entitled to one vote on each proposal.

Proposal No. 1.   Approval of Proposal No. 1 requires the affirmative vote of a majority of our outstanding shares of capital stock entitled to vote at the Special Meeting. Abstentions will have the same effect as a vote against the proposal. There should be no broker “non-votes” on the proposal because brokers should have discretion to vote on this proposal if beneficial owners do not provide voting instructions for this proposal, as described in more detail below. If there are any broker non-votes, they will have the same effect as a vote against the proposal.

Proposal No. 2.   Approval of Proposal No. 2 requires the affirmative vote of a majority of the shares cast on the proposal at the Special Meeting. Abstentions will have the same effect as a vote against the proposal. There should be no broker “non-votes” on the proposal because brokers should have discretion to vote on this proposal if beneficial owners do not provide voting instructions for this proposal, as described in more detail below. If there are any broker non-votes, they will have no effect on the outcome of the proposal.

Effect of Abstentions and Broker Non-Votes

An abstention represents a stockholder’s affirmative choice to decline to vote on a proposal. If a stockholder indicates on its proxy card that it wishes to abstain from voting its shares, or if a broker, bank or other nominee causes abstentions to be recorded for shares, these shares will be considered present and entitled to vote at the Special Meeting for purposes of determining the presence or absence of a quorum, and will count as votes “AGAINST” a proposal, regardless of whether such shares are present in person or represented by proxy at the Special Meeting.

1

Broker non-votes typically occur when a beneficial owner of shares held in “street name” does not give instructions to the broker, bank or other nominee, as applicable, as to how to vote on matters deemed “non-routine”. Generally, if shares are held in street name, the beneficial owner of the shares is entitled to give voting instructions to the broker, bank or other nominee holding the shares. If the beneficial owner does not provide voting instructions, the broker, bank or other nominee can still vote the shares with respect to matters that are considered to be “routine,” but not with respect to matters that are considered to be “non-routine”.

We have been advised that Proposal No. 1 and Proposal No. 2 will likely be considered “routine matters”. Accordingly, if you hold your shares of common stock in “street name”, your failure to give your broker, bank or other nominee voting instructions will not prevent your shares from being voted in favor of Proposal No.1 or Proposal No. 2. Stockholders who hold their shares in “street name” and do not wish their shares to be voted in favor of, or who wish to abstain with respect to, either or both of Proposal No. 1 and Proposal No. 2 should instruct their broker, bank or other nominee to vote against or abstain with respect to, as the case may be, such proposals.

We encourage you to vote promptly, even if you plan to attend the Special Meeting.

Voting Instructions

If you vote by telephone or internet or by marking, signing, dating and returning your proxy card or otherwise appropriately complete and submit your voting instructions, the persons named as proxies will follow your voting instructions. If no choice is indicated on the proxy card, but the proxy card is signed, the shares will be voted as the Board recommends on each proposal. Many banks and brokerage firms have a process for their beneficial owners to provide instructions via telephone or the internet. The voting form that you receive from your bank, broker or other nominee will contain instructions for voting.

Depending on how you hold your shares, you may vote in one of the following ways:

Stockholders of Record:   You may vote (1) by mailing your signed and dated proxy card or voter instruction card in the prepaid envelope, (2) over the internet at proxyvote.com, (3) by telephone at 1-800-690-6903 (toll-free), or (4) by attending the Special Meeting and voting in person. Please follow the instructions provided on the proxy card and have the proxy card with you if you vote by internet or telephone.

Beneficial Stockholders:   Your bank, broker or other nominee will provide you with a voting instruction card for you to use to instruct them on how to vote your shares. Check the instructions provided by your bank, broker or other nominee to see which options are available to you. However, since you are not the stockholder of record, you may not vote your shares in person at the Special Meeting unless you request and obtain a valid proxy from your bank, broker or other nominee.

Votes submitted by telephone or via the internet must be received by 11:59 p.m. Eastern Time on September 6, 2023. Submitting your proxy by telephone or via the internet will not affect your right to vote in person should you later decide to attend the Special Meeting in person.

Revoking or Changing Your Vote

If you are a stockholder of record, you may revoke your proxy and change your vote by returning a later-dated, signed proxy card or delivering written instructions to the Corporate Secretary (which must be received before the polls close at the Special Meeting), by voting again by internet or telephone (by 11:59 p.m. Eastern Time on September 6, 2023), or by voting again at the Special Meeting. Attendance at the Special Meeting will not in and of itself cause your previously voted proxy to be revoked unless you specifically so request or vote again at the Special Meeting. If your shares are held in an account by a bank, brokerage firm or other nominee, you may change your vote by submitting new voting instructions to your bank, brokerage firm or other nominee or, if you have obtained a legal proxy from your bank, brokerage firm or other nominee giving you the right to vote your shares, by attending the Special Meeting and voting in person.

Electronic Availability of Proxy Statement

Pursuant to rules adopted by the SEC, we are making this Proxy Statement and related materials available to stockholders electronically via the internet at www.proxyvote.com. Please review the enclosed

2

proxy card for instructions on how to access these proxy materials and how to vote online. We are constantly focused on improving the ways people connect with information and believe that providing access to our proxy materials over the internet increases the ease and ability of our stockholders to connect with the information they need for the Special Meeting.

Solicitation of Proxies

We will bear the cost of soliciting proxies. We have engaged Alliance Advisors to assist in the solicitation of proxies for the Special Meeting and have agreed to pay Alliance Advisors a fee of $15,000. We will also reimburse Alliance Advisors for reasonable and customary out-of-pocket expenses. In addition, we will request banks, brokers and other intermediaries holding shares of our common stock beneficially owned by others to obtain proxies from the beneficial owners and will reimburse them for their reasonable, out-of-pocket costs for forwarding proxy and solicitation material to the beneficial owners of common stock. We may use the services of our officers, directors and employees to solicit proxies, personally or by telephone, without additional compensation.

Dissenter’s Rights of Appraisal

Stockholders do not have any dissenter’s rights or appraisal rights in connection with the approval of Proposal No. 1 or Proposal No. 2.

Interest of Certain Persons in Matters to Be Acted Upon

None of our directors or executive officers, nor any of their associates, have any substantial interest, direct or indirect, in Proposal No. 1 or Proposal No. 2.

Voting Results

We will announce preliminary voting results at the Special Meeting. We will report final results in a Form 8-K report filed with the SEC.

PROPOSAL NO. 1

APPROVAL OF AMENDMENT TO AMENDED AND RESTATED CERTIFICATE OF INCORPORATION TO INCREASE AUTHORIZED SHARES OF COMMON STOCK

The Board is asking our stockholders to approve an amendment to the Company’s Amended and Restated Certificate of Incorporation (the “Charter”) to increase the number of authorized shares of common stock from 45,000,000 shares to 80,000,000 shares (the “Charter Amendment”).

The Board proposed this amendment for approval by our stockholders at the Company’s 2023 annual meeting of stockholders that was held on June 8, 2023, but the proposal failed by a narrow margin (1.62% or 469,306 shares) to receive the affirmative vote of a majority of our outstanding shares of capital stock entitled to vote at the 2023 annual meeting.

As discussed in more detail below following the caption “Reasons for the Increase in Authorized Shares,” the Board believes that the availability of additional authorized shares of common stock will be needed to provide us with additional flexibility to issue common stock for a variety of general corporate purposes and allow us to capitalize on important opportunities with respect to our growth, expansion and recruiting priorities.

If our stockholders approve the Charter Amendment, we expect to file a certificate of amendment with the Secretary of State of the State of Delaware to increase the number of authorized shares of our common stock as soon as practicable following stockholder approval. In this regard, upon filing of the proposed Charter Amendment with the Secretary of State of the State of Delaware, the first paragraph of Article IV of the Charter would be amended as follows, with the proposed additions underlined and proposed deletions stricken through:

“The total number of shares of capital stock which the Corporation shall have authority to issue is 50,000,00085,000,000, of which (i) 45,000,00080,000,000 shares shall be a class designated as common stock, par value $0.001 per share (the “Common Stock”), and (ii) 5,000,000 shares shall be a class designated as undesignated preferred stock, par value $0.001 per share (the “Undesignated Preferred Stock”).”

Under the Charter Amendment, the authorized number of shares of preferred stock would remain unchanged.

As of June 30, 2023, our common stock share utilization was as follows:

​	Number of Shares of Common Stock
Authorized for issuance	​	45,000,000
Issued and outstanding	​	31,785,027
Reserved for issuance (excluding equity compensation)	​	4,587,000
Issuable pursuant to outstanding equity awards under equity compensation plans	​	5,349,408
Reserved and available for future issuance under our equity compensation plans	​	739,779
Total share usage (sum of issued and outstanding and reserved for issuance)	​	42,461,214
Total share usage as percentage of authorized	​	94.4%

As a result, only approximately 2,538,786 shares of our common stock (or 5.6% of the total authorized common shares) remain available for future issuance.

The Charter Amendment would increase the number of shares of common stock that we are authorized to issue from 45,000,000 shares to 80,000,000 shares, representing an increase of 35,000,000 shares of authorized common stock.

4

Reasons for the Increase in Authorized Shares

The Board believes that the availability of additional authorized shares of common stock will be needed to provide us with additional flexibility to issue common stock for a variety of general corporate purposes as the Board may determine to be desirable. The additional shares of common stock, if approved, may be used for various purposes without further stockholder approval. This includes, but is not limited to, using common stock as consideration for acquisitions, mergers, business combinations or other corporate transactions, raising equity capital, including any future at-the-market equity programs, conducting convertible debt financings or making modifications to existing convertible debt, adopting additional employee benefit plans or reserving additional shares for issuance under existing plans, implementing stock splits or stock dividends and other general corporate purposes. At present, we do not have any plans, arrangements or understandings to issue any of the additional shares of common stock that would be available as a result of the approval of this proposal, other than through our existing at-the-market offering program and equity compensation plans. However, unless our stockholders approve the Charter Amendment, we may not have sufficient unissued and unreserved authorized shares to engage in similar transactions in the future or to act on important growth, expansion and recruiting priorities when they present.

Our growth to date has largely occurred through incremental expansion using our own resources. We believe, however, that there could be opportunities for the Company’s further growth and expansion that could involve acquiring other companies, businesses and technologies or merging with existing companies. With our current share usage, executing on these opportunities would be difficult if and when they present, particularly if the transactions are structured to involve the transfer or exchange of our capital stock. Similarly, we believe that there are large existing and potential new markets within which we may have opportunities to expand our manufacturing operations or launch new research and development programs. Having additional shares of common stock available for issuance would allow us to, among other things, complete equity financing transactions to raise funds for such expansion and additional research and development programs.

Further, our success also depends in part on our continued ability to attract, retain, and motivate highly qualified management and key personnel. Our business needs dictate that we must have world-class talent in some highly specialized skillsets. If this proposal is not approved by our stockholders, the lack of unissued and unreserved authorized shares of common stock to provide future equity incentive opportunities could adversely impact our ability to attract and retain top tier talent and, as a result, could adversely impact our ability to achieve our growth objectives and other strategic goals.

Effect of Increase in Authorized Shares

The Charter Amendment would not change the number of shares of common stock outstanding, nor will it have any immediate dilutive effect. However, if this proposal is approved, unless otherwise required by applicable law or Nasdaq rules, the Board will be able to issue the additional shares of common stock from time to time in its discretion without further action or authorization by the stockholders. Any future issuance of additional shares of common stock authorized by the Charter Amendment may occur at times or under circumstances as to have a dilutive effect on earnings per share, book value per share or the percentage voting or ownership interest of the present holders of our common stock, none of whom have preemptive rights under the Charter to subscribe for additional securities that we may issue.

The Charter Amendment has been prompted by business and financial considerations. The Board currently is not aware of any attempt by a third-party to accumulate shares of common stock or take control of the Company by means of a merger, tender offer or solicitation in opposition to management or the Board. Moreover, we currently have no plans to issue newly authorized shares of common stock to discourage third parties from attempting to take over the Company. However, the Charter Amendment could, under certain circumstances have an anti-takeover effect or delay or prevent a change in control of the Company by providing the Company the capability to engage in actions that would be dilutive to a potential acquiror, to pursue alternative transactions, or to otherwise increase the potential cost to acquire control of the Company. Thus, while we currently have no intent to use the additional authorized shares as an anti-takeover device, the Charter Amendment may have the effect of discouraging future unsolicited takeover attempts.

5

Once the Charter Amendment is approved, no further action by the stockholders would be necessary prior to the issuance of additional shares of common stock unless required by applicable law or Nasdaq rules. Each of the newly authorized shares of common stock will have the same rights and privileges as currently authorized shares of common stock. Adoption of the Charter Amendment will not affect the rights of the holders of currently outstanding common stock, nor will it change the par value of the common stock.

Vote Required and Board of Directors Recommendation

The affirmative vote of a majority of the outstanding shares of our capital stock entitled to vote at the Special Meeting is required to approve this Proposal No. 1.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU
VOTE “FOR” PROPOSAL NO. 1 AS DESCRIBED IN THIS PROXY STATEMENT.

6

PROPOSAL NO. 2

APPROVAL OF ADJOURNMENT OF THE SPECIAL MEETING

The Board is asking our stockholders to approve adjournment of the Special Meeting if the number of shares of common stock present in person or represented by proxy at the Special Meeting and voting “FOR” the Charter Amendment are insufficient to approve Proposal No. 1. In such an event, adjournment of the Special Meeting will enable us to solicit additional proxies in favor of Proposal No. 1. A stockholder vote may be taken on Proposal No. 1 prior to any such adjournment if there are sufficient votes to approve Proposal No. 1.

The Board believes that, if the number of shares of common stock voted in favor of Proposal No.1 at the Special Meeting is insufficient to approve such proposal, it is in the best interests of our stockholders to enable the Board, for a limited period of time, to continue to seek to obtain a sufficient number of additional votes in favor of the proposal.

If the Special Meeting is adjourned or postponed, Stockholders who have already sent in their proxies may revoke them at any time prior to their use at the Special Meeting as so adjourned or postponed. If the adjournment is for more than thirty days, a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the Special Meeting. For the avoidance of doubt, any proxy authorizing the adjournment of the Special Meeting shall also authorize successive adjournments thereof, at any meeting so adjourned, to the extent necessary for us to solicit additional proxies in favor of Proposal No. 1.

Vote Required and Board of Directors Recommendation

For this Proposal No. 2 to be approved by the stockholders at the Special Meeting, the number of votes cast for approval of this Proposal No. 2 must exceed the aggregate number of votes cast against approval and abstentions.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU
VOTE “FOR” PROPOSAL NO. 2 AS DESCRIBED IN THIS PROXY STATEMENT.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table and footnotes set forth information with respect to the beneficial ownership of our common stock as of June 30, 2023 by:

•

each stockholder, or group of affiliated stockholders, who we know beneficially owns more than 5% of the outstanding shares of our common stock;

•

each of our named executive officers;

•

each of our current directors and nominees; and

•

all of our current directors and current executive officers as a group.

Beneficial ownership of shares is determined under the rules of the SEC and generally includes any shares over which a person exercises sole or shared voting or investment power. Except as indicated by footnote, and subject to applicable community property laws, we believe each person identified in the table possesses sole voting and investment power with respect to all shares of common stock beneficially owned by them.

Applicable percentage ownership in the following table is based on 31,785,027 shares of common stock outstanding as of June 30, 2023. Shares of common stock subject to options currently exercisable or exercisable within 60 days of June 30, 2023, and restricted stock units, or RSUs, which vest or will vest within 60 days of June 30, 2023, are deemed to be outstanding for calculating the number and percentage of outstanding shares of the person holding such options or RSUs, but are not deemed to be outstanding for calculating the percentage ownership of any other person. Beneficial ownership or voting power representing less than 1% is denoted with an asterisk (*).

Unless otherwise noted below, the address of each person listed on the table is c/o Applied Optoelectronics, Inc., 13139 Jess Pirtle Blvd, Sugar Land, Texas 77478.

STOCKHOLDER PROPOSALS OR NOMINATIONS
TO BE PRESENTED AT NEXT ANNUAL MEETING

Pursuant to Rule 14a-8 under the Exchange Act, some stockholder proposals may be eligible for inclusion in our proxy statement for the 2024 annual meeting. These stockholder proposals must be submitted, along with proof of ownership of our stock in accordance with Rule 14a-8(b)(2), to the Corporate Secretary at our principal executive offices no later than the close of business on December 29, 2023 (120 days prior to the anniversary of the date proxy materials for the 2023 annual meeting were released to stockholders). Stockholders must comply with the procedures and requirements of Rule 14a-8 for their proposal to be included on our proxy statement for the 2024 annual meeting.

Submitting a stockholder proposal does not guarantee that we will include it in our Proxy Statement. Our nominating and corporate governance committee reviews all stockholder proposals and makes recommendations to the Board for actions on such proposals.

In addition, our Bylaws provide that any stockholder intending to nominate a candidate for election to the Board or to propose any business at our 2024 annual meeting, other than non-binding proposals presented pursuant to Rule 14a-8 under the Exchange Act, must give notice to the Corporate Secretary at our principal executive offices, not earlier than the close of business on the 120th day nor later than the close of business on the 90th day prior to the first anniversary of the date of the preceding year’s annual meeting as first specified in the notice of meeting (without regard to any postponements or adjournments of such meeting after the notice was first given), which for 2024, will be no earlier than the close of business on February 9, 2024 nor later than the close of business on March 10, 2024. The notice must include the information specified in our Bylaws, including information concerning the nominee or proposal, as the case may be, and information concerning the proposing or nominating stockholder’s ownership of and agreements related to our stock. If the 2024 annual meeting is held more than 30 days before or after June 8, 2024, the first anniversary of the date of the 2023 annual meeting, the stockholder must submit notice of any such nomination and of any such proposal that is not made pursuant to Rule 14a-8 by the later of the 90th day prior to the 2024 annual meeting or the 10th day following the date on which public announcement of the date of such meeting is first made. In addition to satisfying the foregoing requirements under our Bylaws with respect to advance notice of any nomination, any stockholder that intends to solicit proxies in support of director nominees other than the Company’s nominees for the 2024 annual meeting in accordance with SEC Rule 14a-19 must provide notice to the Corporate Secretary at the address above no later than 60 calendar days prior to the anniversary of the previous year’s annual meeting (for the 2024 annual meeting, such notice must be provided by April 9, 2024). Any such notice of intent to solicit proxies must comply with all the requirements of Rule 14a-19. We will not entertain any proposals or nominations at the meeting that do not meet the requirements set forth in our Bylaws. If the stockholder does not also comply with the requirements of Rule 14a-4(c) under the Exchange Act, as applicable, we may exercise discretionary voting under proxies that we solicit to vote in accordance with our best judgment on any stockholder proposal or nomination. To make a submission or request a copy of our Bylaws, stockholders should contact our Corporate Secretary. We strongly encourage stockholders to seek advice from knowledgeable counsel before submitting a proposal or a nomination.

TRANSACTION OF OTHER BUSINESS

As of the date of this Proxy Statement, the Board knows of no other business that will be conducted at the Special Meeting other than as described in this Proxy Statement. If any other matter or matters are properly brought before the meeting or any adjournment or postponement of the meeting, it is the intention of the persons named in the accompanying proxy to vote the proxy on such matters in accordance with their best judgment.

HOUSEHOLDING

The U.S. Securities and Exchange Commission, or SEC, has adopted rules that permit companies and intermediaries, such as brokers, to satisfy the delivery requirements for proxy statements with respect to two or more stockholders sharing the same address by delivering one copy of these materials, other than the proxy card, to those stockholders. This process, which is commonly referred to as “householding,” can mean extra convenience for stockholders and cost savings for the Company. Beneficial stockholders can request

10

information about householding from their banks, brokers, or other nominees. Through householding, stockholders of record who have the same address and last name will receive only one copy of our proxy statement and related materials, unless one or more of these stockholders notifies us that they wish to continue receiving individual copies. This procedure will reduce printing costs and postage fees.

If you are eligible for and would like to participate in householding, but you and other stockholders of record with whom you share an address currently receive multiple copies of the proxy statement and related materials, or if you are receiving multiple copies of these documents and you would like future deliveries for your household to be limited to a single copy, please contact Broadridge Householding Department, in writing, at 51 Mercedes Way, Edgewood, New York 11717, or by phone at (800) 542-1061 or (866) 540-7095. If, at any time, you no longer wish to participate in householding and would prefer to receive separate copies of the proxy statement and related materials, please notify your broker if you are a beneficial stockholder.

By order of the Board,

David Kuo
Chief Legal and Compliance Officer and Corporate Secretary
July 28, 2023
