Explanatory Note

The Company is filing this Amendment to Current Report on Form 8-K solely to include Inline XBRL on the Cover page. No other changes have been made, except to also include Exhibit 104 in Item 9.01 (d).

On September 30, 2019, Applied Optoelectronics, Inc. (the “Company”) executed a Fourth Amendment to Loan Agreement (which included amendments to the loan's Security Agreement and Schedule DD), a Note Modification Agreement and Addendum to Promissory Note (collectively, the "Fourth Amendment Documents"), with Branch Banking and Trust Company (the “Lender”).

Under the terms of the Fourth Amendment Documents (i) the maximum commitment under the line of credit was reduced from $25,000,000 to $20,000,000; (ii) the maturity date of the line of credit was extended from September 28, 2020 to April 2, 2021; (iii) pricing of the unused line fee was adjusted to 0.30% per annum; and (iv) the Covenant Threshold Amount test created in the Third Amendment was removed and replaced with the requirement that if, at any time during any reporting period and pursuant to the most recent loan base report received by Lender, the principal balance outstanding under the line of credit exceeds the lesser of the approved maximum amount of the line of credit commitment amount or the collateral loan value reduced by the reserves, the Company shall immediately prepay the line of credit to the extent necessary to eliminate such excess.

Such reserves shall, at any time that the fixed charge coverage ratio for the loan is less than 1.5 to 1.0, tested for the period of twelve months ended on the applicable covenant measurement date, equal to an amount equal to seventy-five percent (75%) of the lesser of the line of credit commitment amount or collateral loan value reduced by the sum of (i) the principal balance outstanding under the line of credit, (ii) the letter of credit exposure reserve, and (iii) the availability reserve as determined by Lender from the most recent loan base report and otherwise in the sole discretion of Lender after consideration of collections.

The foregoing description of the Fourth Amendment to Loan Agreement and other Fourth Amendment Documents does not purport to be a complete statement of the parties’ rights and obligations under such documents and is qualified in its entirety by reference to the full text of the Fourth Amendment Documents, dated September 30, 2019, copies of which are attached as Exhibit 10.1 through 10.3 to this Current Report on Form 8-K and incorporated by reference herein.
