Cautionary Statement Regarding Forward - Looking Statements 3 Certain information in this presentation contains forward - looking statements, including, but not limited to, information relating to Comtech’s future performance and financial condition, plans and objectives of Comtech’s management and Comtech's assumptions regarding such future performance, financial condition, and plans and objectives that involve certain significant known and unknown risks and uncertainties and other factors not under Comtech's control which may cause its actual results, future performance and financial condition, and achievement of plans and objectives of Comtech's management to be materially different from the results, performance or other expectations implied by these forward - looking statements . Words such as “expects,” “anticipates,” “intends,” “plans,” “believes,” “seeks,” “estimates,” variations of such words and similar expressions are intended to identify such forward - looking statements, which generally are not historical in nature . Forward - looking statements could be affected by factors including, without limitation : the possibility that the expected synergies and benefits from recent acquisitions will not be fully realized, or will not be realized within the anticipated time periods ; the risk that acquired businesses will not be integrated with Comtech successfully ; the possibility of disruption from recent acquisitions, making it more difficult to maintain business and operational relationships or retain key personnel ; the risk that Comtech will be unsuccessful in implementing a tactical shift in its Government Solutions segment away from bidding on large commodity service contracts and toward pursuing contracts for its niche products with higher margins ; the nature and timing of receipt of, and Comtech’s performance on, new or existing orders that can cause significant fluctuations in net sales and operating results ; the timing and funding of government contracts ; adjustments to gross profits on long - term contracts ; risks associated with international sales ; rapid technological change ; evolving industry standards ; new product announcements and enhancements ; changing customer demands and or procurement strategies ; changes in prevailing economic and political conditions ; changes in the price of oil in global markets ; changes in foreign currency exchange rates ; risks associated with legal proceedings, customer claims for indemnification and other similar matters ; risks associated with Comtech's obligations under its Credit Facility ; risks associated with large contracts ; risks associated with the COVID - 19 pandemic and related supply chain disruptions ; and other factors described in this and Comtech's other filings with the SEC . Comtech does not undertake any duty to update any forward - looking statements contained herein .

Use of Non - GAAP Financial Measures In order to provide investors with additional information regarding the Company’s financial results, this presentation contains "Non - GAAP financial measures" under the rules of the SEC . The Company’s Adjusted EBITDA is a Non - GAAP measure that represents earnings (loss) before income taxes, interest (income) and other, write - off of deferred financing costs, interest expense, amortization of stock - based compensation, amortization of intangible assets, depreciation expense, estimated contract settlement costs, settlement of intellectual property litigation, acquisition plan expenses, restructuring costs, COVID - 19 related costs, strategic emerging technology costs (for next - generation satellite technology), facility exit costs and strategic alternatives analysis expenses and other . The Company’s definition of Adjusted EBITDA may differ from the definition of EBITDA or Adjusted EBITDA used by other companies and therefore may not be comparable to similarly titled measures used by other companies . Adjusted EBITDA is also a measure frequently requested by the Company’s investors and analysts . The Company believes that investors and analysts may use Adjusted EBITDA, along with other information contained in its SEC filings, in assessing the Company’s performance and comparability of its results with other companies . The Company’s Non - GAAP financial measures for consolidated operating income, net income and net income per diluted share reflect the GAAP measures as reported, adjusted for certain items as described in the Reconciliation of GAAP to Non - GAAP Financial Measures section of this presentation . These Non - GAAP financial measures have limitations as an analytical tool as they exclude the financial impact of transactions necessary to conduct the Company’s business, such as the granting of equity compensation awards, and are not intended to be an alternative to financial measures prepared in accordance with GAAP . These measures are adjusted as described in the Reconciliation of GAAP to Non - GAAP section, but these adjustments should not be construed as an inference that all of these adjustments or costs are unusual, infrequent or non - recurring . Non - GAAP financial measures should be considered in addition to, and not as a substitute for or superior to, financial measures determined in accordance with GAAP . Investors are advised to carefully review the GAAP financial results that are disclosed in the Company’s SEC filings . The Company has not quantitatively reconciled its fiscal 2022 Adjusted EBITDA target to the most directly comparable GAAP measure because items such as stock - based compensation, adjustments to the provision for income taxes, amortization of intangibles, interest expense and estimated proxy solicitation costs, which are specific items that impact these measures, have not yet occurred, are out of the Company's control, or cannot be predicted . For example, quantification of stock - based compensation expense requires inputs such as the number of shares granted and market price that are not currently ascertainable . Accordingly, reconciliations to the Non - GAAP forward looking metrics are not available without unreasonable effort and such unavailable reconciling items could significantly impact the Company's financial results . 4
