**Item 1.01. Entry into a Material Definitive Agreement.**

 

On March 12, 2026, Applied Optoelectronics, Inc. (the "Company") entered into Amendment No. 1 to the Equity Distribution Agreement (the "Amendment") with Raymond James & Associates, Inc. and Needham & Company, LLC (collectively, the "Sales Agents"), amending the Equity Distribution Agreement dated as of February 26, 2026 among the Company and the Sales Agents (the "Original Agreement" and, together with the Amendment, the "Agreement"). Pursuant to the Agreement, the Company may issue and sell shares of the Company's common stock, par value $0.001 per share (the "Shares") having an aggregate offering price of up to $500 million from time to time through the Sales Agents. The Original Agreement was amended to increase the total amount of Shares that the Company may offer and sell under the Agreement from $250,000,000 to $500,000,000 (which amount includes what we have already sold pursuant to the Agreement prior to the date of the Amendment). As of March 12, 2026, the Company has sold 2,476,307 shares of the Company's common stock with an aggregate offering price of approximately $249,999,983, and the Company may offer and sell an additional aggregate offering price of approximately $250,000,017 following the Amendment.

Upon delivery of a placement notice and subject to the terms and conditions of the Agreement, sales, if any, of the Shares will be made through the Sales Agents in transactions that are deemed to be "at the market" offerings as defined in Rule 415 of the Securities Act of 1933, as amended (the "Securities Act"), including sales made through the facilities of the Nasdaq Global Market, the principal trading market for the Company's common stock, on any other existing trading market for the Company's common stock, to or through a market maker or as otherwise agreed by the Company and the Sales Agents. In the placement notice, the Company will designate the maximum number of Shares to be sold through the Sales Agents, the time period during which sales are requested to be made, the minimum price for the Shares to be sold, and any limitation on the number of Shares that may be sold in any one day. Subject to the terms and conditions of the Agreement, the Sales Agents will use their commercially reasonable efforts to sell Shares on the Company's behalf up to the designated amount specified in the placement notice. The Company has no obligation to sell any Shares under the Agreement and may at any time suspend offers and sales of the Shares under the Agreement.

The Agreement provides that the Sales Agents will be entitled to compensation of 2% of the gross sales price of the Shares sold through the Sales Agents from time to time. The Company has also agreed to reimburse the Sales Agents for certain specified expenses in connection with the registration of Shares under state blue sky laws and any filing with, and clearance of the offering by, the Financial Industry Regulatory Authority Inc., not to exceed $10,000 in the aggregate, and any associated application fees incurred. Additionally, if the Agreement is terminated under certain circumstances, and the Company fails to sell a minimum amount of the Shares as set forth in the Agreement, then the Company has agreed to reimburse the Sales Agents for reasonable out-of-pocket expenses, including the reasonable fees and disbursements of counsel incurred by the Sales Agents, up to a maximum of $30,000 in the aggregate. The Company agreed to indemnify the Sales Agents against certain liabilities, including liabilities under the Securities Act, or to contribute to payments that the Sales Agents may be required to make because of any of those liabilities.

The offering pursuant to the Agreement will terminate upon the sale of all Shares subject to the Agreement. The Agreement may also be terminated by the Company or by the Sales Agents at any time.

The Shares to be issued and sold have been registered under the Securities Act, pursuant to the Company's automatic shelf registration statement on Form S-3ASR (Registration No. 333-283905), including the prospectus contained therein, as supplemented by the prospectus supplement filed with the Securities and Exchange Commission (the "SEC") pursuant to Rule 424(b) under the Securities Act on February 26, 2026 and the amendment to the prospectus supplement dated March 12, 2026.

The foregoing description of the Agreement does not purport to be complete and is qualified in its entirety by reference to the complete text of the Original Agreement, which was filed as Exhibit 1.1 to the Current Report on Form 8-K filed on February 26, 2026 and incorporated herein by reference, and the Amendment, which is filed as Exhibit 1.1 to this Current Report on Form 8-K and incorporated herein by reference.

Ladies and Gentlemen:

We have acted as counsel for Applied Optoelectronics, Inc., a Delaware corporation (the "***Company***"), in connection with the issuance and sale by the Company from time to time on a delayed continuous basis pursuant to Rule 415 under the Securities Act of 1933, as amended (the "***Securities Act***"), of (i) securities, including shares of the Company's common stock, $0.001 par value per share (the "***Common Stock***"), registered pursuant to the Registration Statement on Form S-3 (File No. 333-283905) (including the prospectus contained therein, the "***Registration Statement***") filed with the Securities and Exchange Commission (the "***Commission***"); and (ii) the prospectus supplement, dated February 26, 2026 (the "***Prospectus Supplement***"), as amended by Amendment No. 1 to the Prospectus Supplement, as filed with the Commission pursuant to Rule 424(b) under the Securities Act on March 12, 2026 (the "***Amendment***"), relating to the issuance and sale from time to time by the Company of shares of Common Stock with an aggregate offering price of up to $500,000,000 (the "***Shares***"). The Shares are to be issued and sold by the Company pursuant to an Equity Distribution Agreement, dated February 26, 2026 (the "***Original Agreement***") and amended on March 12, 2026 (the "***Distribution Amendment***" and collectively with the Original Agreement, the "***Distribution Agreement***"), among the Company, Raymond James & Associates, Inc. and Needham & Company, LLC. The Original Agreement was filed with the Commission as Exhibit 1.1 to the Company's Current Report, dated February 26, 2026 and the Distribution Amendment will be filed with the Commission as Exhibit 1.1 to the Company's Current Report on Form 8-K, dated March 12, 2026.

For purposes of the opinion we express below, we have examined originals, or copies certified or otherwise identified, of (i) the certificate of incorporation and bylaws, each as amended to date, of the Company (the "***Company Charter Documents***"); (ii) the Registration Statement and all exhibits thereto; (iii) the Prospectus Supplement and all exhibits thereto, (iv) the Amendment and all exhibits thereto; (v) the Distribution Agreement and all exhibits thereto; (vi) the minutes and records of the corporate proceedings of the Company with respect to the filing of the Registration Statement, the Prospectus Supplement and the Amendment and the entering into of the Distribution Agreement; and (vii) such other corporate records of the Company as we have deemed necessary or appropriate for purposes of the opinion hereafter expressed.

As to questions of fact material to the opinion expressed below, we have, without independent verification of their accuracy, relied to the extent we deem reasonably appropriate upon the representations and warranties of the Company contained in such documents, records, certificates, instruments or representations furnished or made available to us by the Company.

In making the foregoing examination, we have assumed (i) the genuineness of all signatures, (ii) the authenticity of all documents submitted to us as originals, (iii) the conformity to original documents of all documents submitted to us as certified or photostatic copies, (iv) that all agreements or instruments we have examined are the valid, binding and enforceable obligations of the parties thereto, and (v) that all factual information on which we have relied was accurate and complete.

We have also assumed that (i) the Amendment has been timely filed with the Commission; (ii) the Company will issue and deliver the Shares in the manner contemplated by the Registration Statement, the Prospectus Supplement, the Amendment and the Distribution Agreement; (iii) the Shares will be issued in compliance with applicable federal and state securities law; (iv) no stop orders of the Commission preventing or suspending the use of the Prospectus Supplement and/or the Amendment will have been issued; and (v) the Company will receive consideration for the issuance of the Shares that is at least equal to the par value of the Common Stock.

Based on the foregoing, and subject to the limitations and qualifications set forth herein, we are of the opinion that when issued and paid for in accordance with the terms and conditions of the Distribution Agreement, the Shares will be validly issued, fully paid and nonassessable.

Applied Optoelectronics, Inc.

March 12, 2026

The opinion expressed herein is limited to the Delaware General Corporation Law as in effect on the date hereof.

We hereby consent to the filing of this letter as Exhibit 5.1 to the Current Report on Form 8-K to be filed by the Company in connection with the issuance and sale of the Shares in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Securities Act and to the reference to our firm therein and in the Prospectus Supplement under the caption "Legal Matters."
