Reports Second Quarter 2026 Results

Sugar Land, Texas, August 6, 2026 – Applied Optoelectronics,

Inc. (NASDAQ: AAOI) (“AOI”), a leading provider of advanced optical and HFC networking products that power AI, today announced

financial results for its second quarter ended June 30, 2026.

“Q2 was a pivotal quarter for AOI. We delivered record revenue

for our fifth consecutive quarter and achieved an important milestone as T1we returned to non-GAAP profitability in the quarter. Further,

T2we saw a strong volume ramp of our 800G products, which more than doubled sequentially,” said Dr. Thompson Lin, AOI’s Founder,

President and Chief Executive Officer. “Strong demand for high-speed optics alongside T3high-volume adoption of our 1.8 GHz CATV products

generated powerful results during the quarter. T4We continue to see robust customer engagement around our 800G transceivers and 1.6 Tb products,

and T5we forecast that demand will continue to outpace our production capacity through mid-2027. We continue to believe the fundamental

drivers of long-term demand for our business remain robust and T6we are uniquely positioned as a key supplier to the AI, cloud infrastructure,

and CATV markets.”

“We’re pleased to deliver second quarter results that were

in line with or better than our expectations,” said Dr. Stefan Murry, AOI’s Chief Financial Officer and Chief Strategy Officer.

“During Q2, we continued to make solid progress on our production capacity ramp, particularly for our 800G and 1.6Tb products. We

have a total manufacturing capacity approaching 200,000 units per month and T7continue to expect by the end of this year that we will be

capable of producing around 650,000 pieces of 800G and 1.6 Tb products per month. We’re working hard to expand our capacity, and

T8we continue to anticipate steady sequential revenue growth this year.”

Non-GAAP Financial Measures

We provide non-GAAP gross margin, non-GAAP net income (loss), and non-GAAP

earnings (loss) per share, and non-GAAP Adjusted EBITDA to eliminate the impact of items that we do not consider indicative of our overall

operating performance. To arrive at our non-GAAP gross margin, we exclude stock-based compensation and related expenses, expenses associated

with discontinued products, and non-recurring (income) expenses, if any, from our GAAP gross margin. To arrive at our non-GAAP net income

(loss), we exclude all amortization of intangible assets, stock-based compensation expense, non-recurring expenses, unrealized foreign

exchange loss (gain), losses from the disposal of idle assets, if any, and non-GAAP tax benefit (expenses) from our GAAP net income (loss).

Included in our non-recurring expenses in Q2 2026 and Q2 2025 are employee severance expenses

(if any) and legal expenses associated with litigation and certain legal and advisory expenses associated with purchase termination or

patent protection. In computing our non-GAAP income tax benefit (expense), we have applied an estimate of our annual effective income

tax rate and applied it to our net income before income taxes. Our non-GAAP Adjusted EBITDA is calculated by excluding depreciation expense,

non-GAAP tax benefit (expense), and interest (income) expense, as well as the items excluded from non-GAAP net income (loss), from our

GAAP net income (loss). Our non-GAAP diluted net earnings (loss) per share is calculated by dividing our non-GAAP net gain (loss) by the

fully diluted share count (for periods in which non-GAAP net income is positive) or basic share count (for periods in which our non-GAAP

net income is negative).

We believe that our non-GAAP measures are useful to investors in evaluating

our operating performance for the following reasons:

•

We

believe that elimination of items such as amortization of intangible assets, stock-based compensation expense, non-recurring revenue

and expenses, losses from the disposal of idle assets, unrealized foreign exchange gain or loss, and depreciation on certain equipment

undergoing reconfiguration is appropriate because treatment of these items may vary for reasons unrelated to our overall operating performance;

•

We

believe that elimination of expenses associated with discontinued products, including depreciation and inventory obsolescence is appropriate

because these expenses are not indicative of our ongoing operations;

•

We

believe that estimating non-GAAP income taxes allows comparison with prior periods and provides additional information regarding the

generation of potential future deferred tax assets;

•

We

believe that non-GAAP measures provide better comparability with our past financial performance, period-to-period results and with our

peer companies, many of which also use similar non-GAAP financial measures; and

•

We

anticipate that investors and securities analysts will utilize non-GAAP measures as a supplement to GAAP measures to evaluate our overall

operating performance.

A reconciliation of our GAAP net income (loss), GAAP total gross profit,

GAAP earnings (loss), and GAAP earnings (loss) per share for Q2 2026 to our non-GAAP net income (loss), non-GAAP total gross profit, Adjusted

EBITDA, and earnings (loss) per share, respectively, is provided below, together with corresponding reconciliations for Q2 2025.

Non-GAAP measures should not be considered as an alternative to gross

profit, net income (loss), earnings (loss) per share, or any other measure of financial performance calculated and presented in accordance

with GAAP. Our non-GAAP measures may not be comparable to similarly titled measures of other organizations because other organizations

may not calculate such other non-GAAP measures in the same manner. We have not reconciled the non-GAAP measures included in our guidance

to the appropriate GAAP financial measures because the GAAP measures are not readily determinable on a forward-looking basis. GAAP measures

that impact our non-GAAP financial measures may include stock-based compensation expense, non-recurring expenses, amortization of intangible

assets, unrealized exchange loss (gain), asset impairment charges, loss (gain) from disposal of idle assets, and changes in the fair value

of our convertible notes. These GAAP measures cannot be reasonably predicted and may directly impact our non-GAAP gross margin, our non-GAAP

net income and our non-GAAP fully-diluted earnings per share, although changes with respect to certain of these measures may offset other

changes. In addition, certain of these measures are out of our control. Accordingly, a reconciliation of the non-GAAP financial measure

guidance to the corresponding GAAP measures is not available without unreasonable effort.
