Chandler, Arizona

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Comtech Telecommunications Corp. and subsidiaries (the "Company") as of July 31, 2026 and 2025, the related consolidated statements of operations, convertible preferred stock and stockholders’ equity, and cash flows, for each of the two years in the period ended July 31, 2026, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of July 31, 2026 and 2025, and the results of its operations and its cash flows for each of the two years in the period ended July 31, 2026, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of July 31, 2026, based on criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated October 14, 2026, expressed an adverse opinion on the Company’s internal control over financial reporting because of material weaknesses.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current-period audit of the financial statements that were communicated or required to be communicated to the audit committee and that (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Net Sales – Over Time Accounting Using the Cost-to-Cost Measure for Specific Identified Material Contracts — Refer to Note 1 to the Financial Statements

The Company’s determination of revenue recognition for specific identified material contracts accounted for over time involves estimating the total costs needed to complete the specific identified contracts and updating those estimates throughout the life of those specific identified contracts. This requires management to make significant estimates related to forecasts of future costs for the identified specific contracts. Changes in these estimates for the identified specific contracts could have a significant impact on the Company’s results of operations.

Given the significant judgment and estimates used in management’s projections, auditing the Company’s estimates at completion and estimates to completion involved especially subjective judgment.

F - 2

Our audit procedures related to the Company’s determination of revenue recognition for specific identified material contracts accounted for over time included the following, among others:

•We tested the effectiveness of the controls over the development of the initial contract cost to complete estimate and monitoring of estimates at completion and estimates to completion.

•For each specific identified material contract selected, we performed the following:

◦Evaluated whether the contract was properly included in management’s calculation of over time revenue based on the terms and conditions of each contract, including whether continuous transfer of control to the customer occurred as progress was made toward fulfilling the performance obligation.

◦Compared the transaction prices to the consideration expected to be received based on current rights and obligations under the contracts and any modifications that were agreed upon with the customers.

◦Confirmed certain items with the customer, such as contract amount, approved change orders, invoices received, payments made, liquidated damages, if any, and amounts owed to the Company.

◦Tested management’s identification of distinct performance obligations by evaluating whether the underlying goods, services, or both were highly interdependent and interrelated.

◦Evaluated the estimates of total cost and profit for the performance obligation by:

▪Performing a retrospective review by comparing the estimated margins at contract inception or as of the prior year-end, as applicable, to the actual margins as of year-end in order to assess management’s ability to accurately estimate costs.

▪Inquiring and corroborating the estimates to complete and the estimates at completion with the Project Manager (i.e., someone outside of Finance/Accounting) to understand significant variances in costs and completeness of the estimates at completion and estimates to completion.

▪Testing the estimates to complete through a combination of tests of details, in which we selected individual costs within the estimate to complete and obtained supporting documentation, and where we developed an expectation of the estimate to complete and compared it to the recorded balance.

◦Tested the accuracy and completeness of costs incurred during the current fiscal year. This testing included agreeing labor costs to employee timesheets and agreeing the labor rate to either rates agreed upon with the customer in the contract or rates from the Company’s payroll records.

◦Tested the mathematical accuracy of management’s calculation of revenue for the performance obligation.

Goodwill — Refer to Note 15 to the financial statements

The Company’s evaluation of goodwill for impairment involves the comparison of the fair value of its reporting unit to its carrying value. The Company used a combination of a market approach and the income approach, also known as the discounted cash flow ("DCF") method, to determine the present value of cash flows to estimate fair value. In the DCF, the future cash flows for the Company’s reporting unit was projected based on its estimates, at that time, of future revenues, operating income and other factors (such as working capital and capital expenditures). Changes in these assumptions could have a significant impact on either the fair value, the amount of any goodwill impairment charge, or both.

Allerium’s goodwill balance was $176.1 million as of July 31, 2026. The fair value of Allerium exceeded its carrying value by 7.9% as of the measurement date and, therefore, no impairment was recognized.

F - 3

We identified goodwill for Allerium as a critical audit matter because of the significant judgments made by management to estimate the fair value of the reporting unit and the differences between their fair value and carrying value. This required a high degree of auditor judgment and an increased extent of effort, including the need to involve our fair value specialists, when performing audit procedures to evaluate the reasonableness of management’s estimates and assumptions related to selection of the discount rate and forecasts of future revenue and operating margins.

Our audit procedures related to the discount rate and forecasts of future revenue and operating margins used by management to estimate the fair value of Allerium included the following, among others:

•We tested the effectiveness of controls over management’s goodwill impairment evaluation, including those over the determination of the fair value of the reporting unit, such as controls related to management’s selection of the discount rate and forecasts of future revenue and operating margins.

•We evaluated management’s ability to accurately forecast future revenues and operating margins by comparing actual results to management’s historical forecasts.

•We evaluated the reasonableness of management’s revenue forecasts and forecasts of operating margins by comparing the forecasts to:

◦Historical revenues and operating margins.

◦Internal communications to management and the Board of Directors.

◦Forecasted information included in Company press releases as well as in analyst and industry reports for the Company and certain of its peer companies.

•With the assistance of our fair value specialists, we evaluated the reasonableness of the (1) valuation methodology and (2) discount rate by:

◦Testing the source information underlying the determination of the discount rate and the mathematical accuracy of the calculation.

◦Developing a range of independent estimates and comparing those to the discount rate selected by management.

◦Assessing the concluded fair value of the sum of the aggregate reporting units relative to the business enterprise as a whole based on market prices as of the impairment assessment date.

Debt - Refer to Notes 8 and 9 to the Financial Statements

The Company has current and long-term debt of $121.0 million and $84.3 million, respectively, as of July 31, 2026. Debt is recorded at initial fair value, which normally reflects the proceeds received by the Company, net of debt issuance costs. Debt is subsequently stated at amortized cost. Debt issuance costs, discounts and premiums are generally amortized to interest expense using the effective interest method, over the term of the debt. Debt issuance costs related to a recognized debt liability are presented as a direct deduction of the carrying amount of that debt, consistent with debt discounts. Debt issuance costs related to the Company's revolving facility are deferred and recorded as an asset. Debt issuance costs paid to lenders related to a recognized debt liability are netted against the proceeds from the related debt while debt issuance costs paid to third parties are expensed as incurred. Debt instruments are also evaluated by the Company for the existence of features that must be separated and accounted for as a derivative. During the year ended July 31, 2026, the Company entered into various debt transactions that involved the modification of existing debt. We identified the accounting for debt and the related debt transactions, as a critical audit matter because of the complexity involved in (i) evaluating the accounting for the debt amendments including whether such transactions resulted in a debt modification or extinguishment and the associated impact on debt issuance costs, and (ii) evaluating the existence of and accounting for features embedded in amended debt agreements that must be separated and accounted for as a derivative. This required an increased extent of effort due to the potential magnitude and complexity of the debt transactions, including the assistance of our professionals with specialized knowledge and skills in the relevant technical accounting guidance required when performing audit procedures to address these matters.

F - 4

Our audit procedures related to the accounting for debt and related debt transactions included the following, among others:

•We tested the effectiveness of controls over debt including those over the application of relevant technical accounting guidance to complex and significant debt transactions.

•We evaluated and tested management's debt modification or extinguishment analysis by:

◦Testing the accuracy and completeness, including mathematical accuracy, of management's analysis.

◦Evaluating management's analysis over whether the debt transactions met the conditions to be treated as a debt modification or extinguishment by evaluating it against the relevant technical accounting guidance.

•We evaluated the conclusions reached by management on its analysis of the terms in the amended debt agreements to evaluate the existence of features in the amended debt agreements that must be separated and accounted for as a derivative by:

◦Reading the terms for all debt agreements to evaluate the existence of features in the amended debt agreements that must be separated and accounted for as a derivative.

◦Evaluating management's analysis identifying the existence of and accounting for the features in the amended debt agreements that must be separated and accounted for as a derivative by evaluating it against the relevant technical accounting guidance.

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of Comtech Telecommunications Corp. and subsidiaries (the "Company") as of July 31, 2026, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, because of the effect of the material weaknesses identified below on the achievement of the objectives of the control criteria, the Company has not maintained effective internal control over financial reporting as of July 31, 2026, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended July 31, 2026, of the Company and our report dated October 14, 2026, expressed an unqualified opinion on those financial statements.

Basis for Opinion

The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Material Weaknesses

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the company’s annual or interim financial statements will not be prevented or detected on a timely basis.

F - 6

The following material weaknesses have been identified and included in management's assessment:

•The Company did not design and maintain an effective control environment commensurate with their financial reporting requirements based on the criteria in the COSO framework, as the Company lacked a sufficient complement of resources with an appropriate level of knowledge and experience to establish effective processes and controls. The control environment material weakness contributed to another material weakness related to control activities over revenue recognition and contract liabilities, where the Company did not design and implement effective control activities.

These material weaknesses were considered in determining the nature, timing, and extent of audit tests applied in our audit of the consolidated financial statements, as of and for the year ended July 31, 2026, of the Company, and this report does not affect our report on such financial statements.
