Material Agreement, Financial Obligation (Form 8-K)

On June 11, 2026, Global Technology, Inc. ("Global Technology"), a wholly owned subsidiary of Applied Optoelectronics, Inc., entered into a one-year credit line agreement with Shanghai Pudong Development Bank Co., Ltd. in Ningbo City, China (the "Bank"), pursuant to which the Bank agreed to provide Global Technology with a credit line in an aggregate amount of up to RMB 500,000,000 (the "Credit Line").

The Credit Line supersedes the prior credit facility agreement between Global Technology and the Bank dated July 29, 2025, which provided for a maximum credit facility of RMB 250,000,000 (the "Original Credit Facility"). The Credit Line increases Original Credit Facility from RMB 250,000,000 to RMB 500,000,000 to support Global Technology's working capital needs and general business operations. Pursuant to the Credit Line, any amounts previously extended by the Bank under the Original Credit Facility will remain outstanding and reduce the amount available for borrowing under the Credit Line.

The Credit Line may be utilized for the following financing arrangements: (i) working capital loans in an aggregate principal amount of up to RMB 150,000,000, which is shared with the fixed asset loan sublimit, (ii) fixed asset loans in an aggregate principal amount of up to RMB 300,000,000, and (iii) bank acceptance bills in an aggregate principal amount of up to RMB 200,000,000. The fixed asset loan portion of the Credit Line is non-revolving, while the working capital loan and bank acceptance bill portions are available on a revolving basis.

Global Technology may draw upon the Credit Line on an as-needed basis at any time during the period from May 21, 2026 through May 21, 2027; provided, however, the Bank may revoke the Credit Line at any time at its sole discretion. The Bank may do so without prior notice in the event of changes in applicable laws, regulations, or policies, restrictions imposed by government monetary or financial regulatory policies, changes in market conditions, fund positions, financial costs, the Bank's own business needs, or a deterioration in Global Technology's credit condition. The interest rate applicable to each draw will be determined by mutual agreement between the Bank and Global Technology and specified in the loan documents executed at the time of such draw.

Global Technology's obligations under the Credit Line will be secured by the real property previously mortgaged to the Bank in connection with the Original Credit Facility. The Credit Line contains rights and obligations, representations and warranties, and events of default applicable to Global Technology that are customary for agreements of this type.

The foregoing description of the Credit Line does not purport to be a complete statement of the parties' rights and obligations under the agreements and is qualified in its entirety by reference to the full text of the Financing Credit Line Agreement, an English translation of which is attached as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated by reference herein.

The information as set forth in Item 1.01 of this Current Report on Form 8-K is incorporated by reference into Item 2.03.
