Legal Notice Regarding Forward-Looking Statements

This press release contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934, including, but not limited to, statements related to our expectations regarding: net revenue; gross margins; operating expenses; operating income (loss), including stranded costs associated with the disposition of the Video business; tax expense and tax rate, and net income (loss) per diluted share. Our expectations regarding these matters may not materialize, and actual results in future periods are subject to risks and uncertainties that could cause actual results to differ materially from those projected. These risks include, but are not limited to, in no particular order, the following: customer concentration and consolidation; loss of one or more key customers; delays or decreases in capital spending in the cable or telco industries; the possibility that our products will not generate sales that are commensurate with our expectations or that our cost of revenue or operating expenses may exceed our expectations; the market and technology trends underlying our Broadband business will not continue to develop in their current direction or pace; the impact of tariffs and general economic conditions on our sales and operations; the mix of products and services sold in various geographies and the effect it has on gross margins; our ability to develop new and enhanced products in a timely manner and market acceptance of our new or existing products; risks associated with our international operations; exchange rate fluctuations of the currencies in which we conduct business; risks associated with our cOS™ product solutions; dependence on various broadband industry trends; inventory management; the lack of timely availability or the impact of increases in the prices of parts or raw materials necessary to produce our products; the effect of competition, on both revenue and gross margins; difficulties associated with rapid technological changes in our markets; risks associated with unpredictable sales cycles; our dependence on contract manufacturers and sole or limited source suppliers; stock repurchases may not be conducted in the timeframe or in the manner we expect, or at all; and the impact on our business of natural disasters. In some cases, you can identify forward-looking statements by terminology such as, “may,” “will,” “should,” “expects,” “plans,” “anticipates,” “could,” “believes,” “intends,” “estimates,” “predicts,” “potential,” or “continue” or the negative of these terms or other comparable terminology. The forward-looking statements contained in this press release are also subject to other risks and uncertainties, including those more fully described in Harmonic's filings with the Securities and Exchange Commission, including our most recent Annual Report on Form 10-K for the year ended December 31, 2025, our most recent Quarterly Report on Form 10-Q and our Current Reports on Form 8-K. The forward-looking statements in this press release are based on information available to the Company as of the date hereof, and Harmonic disclaims any obligation to update any forward-looking statements.

Use of Non-GAAP Financial Measures

The Company reports its financial results in accordance with accounting principles generally accepted in the United States (“GAAP” or referred to herein as “reported”). However, management believes that certain Non-GAAP financial measures provide management and other users with additional meaningful financial information that should be considered when assessing our ongoing performance. Our management regularly uses our supplemental Non-GAAP financial measures internally to understand, manage and evaluate our business, establish operating budgets, set internal measurement targets and make operating decisions.

These Non-GAAP measures are not in accordance with, or an alternative for, measures prepared in accordance with generally accepted accounting principles and may be different from Non-GAAP measures used by other companies. In addition, these Non-GAAP measures are not based on any comprehensive set of accounting rules or principles. The Company believes that Non-GAAP measures have limitations in that they do not reflect all of the amounts associated with Harmonic's results of operations as determined in accordance with GAAP and that these measures should only be used to evaluate Harmonic's results of operations in conjunction with the corresponding GAAP measures.

The Company believes that the presentation of Non-GAAP measures, when shown in conjunction with the corresponding GAAP measures, provide useful information to investors and management regarding financial and business trends relating to its financial condition and its historical and projected results of operations. Non-GAAP financial measures should be viewed in addition to, and not as an alternative to, the Company’s reported results prepared in accordance with GAAP.

The Non-GAAP measures presented here are: Gross profit, operating expenses, income (loss) from operations, non-operating expenses and net income (loss), and net income (loss) per diluted share. The presentation of Non-GAAP information is not intended to be considered in isolation or as a substitute for results prepared in accordance with GAAP, and is not necessarily comparable to Non-GAAP results published by other companies. A reconciliation of the historical Non-GAAP financial measures discussed in this press release to the most directly comparable historical GAAP financial measures is included with the financial statements provided with this press release. The Non-GAAP adjustments described below have historically been excluded from our GAAP financial measures.

Our Non-GAAP financial measures reflect adjustments based on the following items, as well as the related income tax effects:

Stock-based compensation - Although stock-based compensation is a key incentive offered to our employees, we continue to evaluate our business performance excluding stock-based compensation expenses. We believe that management is limited in its ability to project the impact stock-based compensation would have on our operating results. In addition, for comparability purposes, we believe it is useful to provide a Non-GAAP financial measure that excludes stock-based compensation in order to better understand the long-term performance of our core business and to facilitate the comparison of our results to the results of our peer companies.

Non-recurring advisory fees - There were non-recurring costs that we excluded from Non-GAAP results relating to professional accounting, tax and legal fees associated with strategic corporate initiatives.

Divestiture related employee compensation costs - There were non-recurring costs that we excluded from Non-GAAP results relating to employee compensation costs resulting from the divestiture.

Discrete tax items and tax effect of Non-GAAP adjustments - The income tax effect of Non-GAAP adjustments relates to the tax effect of the adjustments that we incorporate into Non-GAAP financial measures in order to provide a more meaningful measure of Non-GAAP net income. This non-recurring adjustment has been excluded from the Company’s non-GAAP tax rate and non-GAAP financial measures, as management believes exclusion of this item provides more meaningful period-to-period comparisons of ongoing operating performance
