Accounting Policies [Abstract]
Summary of Significant Accounting and Reporting Policies	Summary of Significant Accounting and Reporting Policies Principles of Consolidation The accompanying consolidated financial statements include the accounts of Comtech Telecommunications Corp. and its subsidiaries ("Comtech," "we," "us," or "our"), all of which are wholly-owned. All significant intercompany balances and transactions have been eliminated in consolidation. Nature of Business We design, produce and market innovative products, systems and services for advanced communications solutions. We conduct our business through two reportable operating segments: Satellite and Space Communications and Terrestrial and Wireless Networks. Our business is highly competitive and characterized by rapid technological change. Our growth and financial position depends on our ability to keep pace with such changes and developments and to respond to the sophisticated requirements of an increasing variety of secure wireless communications technology users, among other things. Many of our competitors are substantially larger, and have significantly greater financial, marketing and operating resources and broader product lines than our own. A significant technological or sales breakthrough by others, including smaller competitors or new companies, could have a material adverse effect on our business. In addition, certain of our customers have technological capabilities in our product areas and could choose to replace our products with their own. International sales expose us to certain risks, including barriers to trade, fluctuations in foreign currency exchange rates (which may make our products less price competitive), political and economic instability, availability of suitable export financing, export license requirements, tariff regulations, and other United States ("U.S.") and foreign regulations that may apply to the export of our products, as well as the generally greater difficulties of doing business abroad. We attempt to reduce the risk of doing business in foreign countries by seeking contracts denominated in U.S. dollars, advance or milestone payments, credit insurance and irrevocable letters of credit in our favor. Liquidity and Going Concern Pursuant to the requirements of ASC Topic 205-40, " Disclosure of Uncertainties About an Entity’s Ability to Continue as a Going Concern ," we are required to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about our ability to continue as a going concern. This evaluation does not take into consideration the potential mitigating effect of our plans that have not been fully implemented or are not within our control as of the date the audited Consolidated Financial Statements are issued. When substantial doubt exists, we are required to evaluate whether the mitigating effect of our plans sufficiently alleviates substantial doubt about our ability to continue as a going concern. The mitigating effect of our plans, however, is only considered if both (i) it is probable that the plans will be effectively implemented within one year after the date that the Consolidated Financial Statements are issued, and (ii) it is probable that the plans, when implemented, will mitigate the relevant conditions or events that raise substantial doubt about our ability to continue as a going concern within one year after the date that the Consolidated Financial Statements are issued. As of the date these financial statements were issued (the "issuance date"), we evaluated whether the following adverse conditions, when considered in the aggregate, raise substantial doubt about our ability to continue as a going concern over the next twelve months beyond the issuance date. Over the past three fiscal years, we incurred operating losses of $79,890,000, $14,660,000 and $33,752,000 in fiscal 2024, 2023 and 2022, respectively. In addition, over the past three fiscal years, net cash used in operating activities was $54,495,000 and $4,433,000 in fiscal 2024 and 2023, respectively, and net cash provided by operating activities was $1,997,000 in fiscal 2022. Our ability to meet future anticipated liquidity needs over the next year beyond the issuance date will largely depend on our ability to generate positive cash inflows from operations, maximize our borrowing capacity under our Credit Facility, as discussed further below, and or secure other sources of outside capital. While we believe we will be able to generate sufficient positive cash inflows, maximize our borrowing capacity and secure outside capital, there can be no assurance our plans will be successfully implemented and, as such, we may be unable to continue as a going concern over the next year beyond the issuance date. As discussed further in Note (8) – “Credit Facility,” on June 17, 2024, we entered into a $222,000,000 credit facility with a new syndicate of lenders, which replaced our prior credit facility. As further discussed below, we subsequently amended the credit facility on October 17, 2024 (the "Credit Facility"). The Credit Facility consists of a committed $162,000,000 term loan (“Term Loan”) and $60,000,000 revolving loan (“Revolver Loan”). At July 31, 2024 and October 25, 2024 (the date closest to the issuance date), total outstanding borrowings under the Credit Facility were $194,163,000 and $199,067,000, respectively. At both July 31, 2024 and October 25, 2024, $32,500,000 was drawn on the Revolver Loan. As of the issuance date, our available sources of liquidity approximate $28,700,000, consisting solely of qualified cash and cash equivalents. That is, our available sources of liquidity do not include the remaining portion of the committed Revolver Loan due to the lenders' consent right, discussed below, to any borrowings that exceed $32,500,000. The Credit Facility, among other things, requires compliance with new restrictive and financial covenants, including: a maximum allowable Net Leverage Ratio of 3.25x for the fiscal quarter ending January 31, 2025; a minimum Fixed Charge Coverage Ratio of 1.20x for the fiscal quarter ending January 31, 2025; a minimum Average Liquidity requirement at each quarter end of $20,000,000; and a minimum EBITDA of $35,000,000 for the fiscal quarter ending October 31, 2025. Such ratios adjust under the Credit Facility in future periods. The Credit Facility was amended on October 17, 2024 to waive certain defaults or events of default, including in connection with our Net Leverage Ratio and Fixed Charge Coverage Ratio covenants as of July 31, 2024. The amendment also provides for, among other things: (i) increases the interest rate margins applicable to the loans; (ii) modifies certain financial and collateral reporting requirements; (iii) provides a lender consent right with respect to $27,500,000 of Revolver Loan borrowings above $32,500,000; (iv) permits the incurrence of $25,000,000 of senior unsecured subordinated debt (as described below); (v) amends the maturity date to the earlier of (x) July 31, 2028 or (y) 90 days prior to the earliest date that the debt under the Subordinated Credit Agreement (as defined below) becomes due and payable; and (vi) suspends financial covenant testing through the end of our fiscal quarter ending January 31, 2025. In addition, we entered into a Subordinated Credit Agreement with the existing holders of our Convertible Preferred Stock (the “Subordinated Credit Agreement”) on October 17, 2024, which provides a subordinated unsecured term loan facility in the aggregate principal amount of $25,000,000 (the “Subordinated Credit Facility”). The proceeds of the Subordinated Credit Facility: (i) cured our default on certain financial covenants under the Credit Facility, as discussed above; (ii) provides additional liquidity to us; and (iii) funds our general working capital needs, including support of our strategic transformation initiatives, as discussed below. Our ability to meet our current obligations as they become due may be impacted by our ability to remain compliant with the financial covenants required by the Credit Facility, or to obtain future waivers or amendments from the lenders in the event compliance is not maintained. While we believe we will be able to secure such waivers or amendments, as needed, there can be no assurance such waivers or amendments will be secured or on terms that are acceptable to us. If we are unable to secure waivers or amendments, the lenders may declare an event of default, which would cause an immediate acceleration and repayment of all outstanding principal, interest and fees due under our Credit Facility. Absent our ability to repay the forgoing amounts upon the declaration of an event of default, the lenders may exercise their rights and remedies under the Credit Facility, which may include, among others, a seizure of substantially all of our assets and/or the liquidation of our operations. If an event of default occurs that allows the lenders to exercise these rights and remedies over the next year beyond the issuance date, we will be unable to continue as a going concern. As of the issuance date, our plans to address our ability to continue as a going concern include, among other things: • executing a strategy to transform Comtech into a pure-play satellite and space communications company (ongoing and future actions supporting our transformation strategy include: an exploration of strategic alternatives for our Terrestrial and Wireless Networks segment, which is well underway; the pursuit of further portfolio-shaping opportunities to enhance profitability, efficiency and focus; and the implementation of additional operational initiatives to both achieve profitable results from operations as well as to align our go-forward cost structure with a pure-play focus on satellite and space communications), as discussed further in Note (18) – “Cost Reduction Activities;” • pursuing initiatives to reduce investments in working capital, namely accounts receivable and inventory; • improving process disciplines to attain and maintain profitable operations by entering into more favorable sales or service contracts; • reevaluating our business plans to identify opportunities (e.g., within our Satellite and Space Communications segment) to focus future investment on our most strategic, high-margin revenue opportunities; • reevaluating our business plans to identify opportunities to further reduce capital expenditures; • seeking opportunities to improve liquidity through any combination of debt and/or equity financing (including possibly restructuring our Credit Facility, Convertible Preferred Stock and/or Subordinated Credit Agreement); and • seeking other strategic transactions and/or measures including, but not limited to, the potential sale or divestiture of assets. While we believe the implementation of some or all of the elements of our plans over the next year beyond the issuance date will be successful, these plans are not all solely within management’s control and, as such, we can provide no assurance our plans are probable of being effectively implemented as of the issuance date. Therefore, the adverse conditions and events described above are uncertainties that raise substantial doubt about our ability to continue as a going concern. The accompanying consolidated financial statements have been prepared on the basis that we will continue to operate as a going concern, which contemplates we will be able to realize assets and settle liabilities and commitments in the normal course of business for the foreseeable future. Accordingly, the accompanying consolidated financial statements do not include any adjustments that may result from the outcome of these uncertainties. Revenue Recognition In accordance with FASB ASC 606 - Revenue from Contracts with Customers ("ASC 606"), we record revenue in an amount that reflects the consideration to which we expect to be entitled in exchange for goods or services promised to customers. Under ASC 606, we follow a five-step model to: (1) identify the contract with our customer; (2) identify our performance obligations in our contract; (3) determine the transaction price for our contract; (4) allocate the transaction price to our performance obligations; and (5) recognize revenue using one of the following two methods: • Over time - We recognize revenue using the over time method when there is a continuous transfer of control to the customer over the contractual period of performance. This generally occurs when we enter into a long-term contract relating to the design, development or manufacture of complex equipment or technology platforms to a buyer’s specification (or to provide services related to the performance of such contracts) for which we have determined there is no alternative use, as defined in ASC 606. Continuous transfer of control is typically supported by contract clauses which allow our customers to unilaterally terminate a contract for convenience, pay for costs incurred plus a reasonable profit and take control of work-in-process. Revenue recognized over time is generally based on the extent of progress toward completion of the related performance obligations. The selection of the method to measure progress requires judgment and is based on the nature of the products or services provided. In certain instances, typically for firm fixed-price contracts, we use the cost-to-cost measure because it best depicts the transfer of control to the customer which occurs as we incur costs on our contracts. Under the cost-to-cost measure, the extent of progress toward completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion, including warranty costs. Revenues, including estimated fees or profits, are recorded proportionally as costs are incurred. Costs to fulfill generally include direct labor, materials, subcontractor costs, other direct costs and an allocation of indirect costs. When these contracts are modified, the additional goods or services are generally not distinct from those already provided. As a result, these modifications form part of an existing contract and we must update the transaction price and our measure of progress for the single performance obligation and recognize a cumulative catch-up to revenue and gross profits. For over time contracts using a cost-to-cost measure of progress, we have an estimate at completion ("EAC") process in which management reviews the progress and execution of our performance obligations. This EAC process requires management judgment relative to assessing risks, estimating contract revenue and costs, and making assumptions for schedule and technical issues. Since certain contracts extend over a long period of time, the impact of revisions in revenue and/or cost estimates during the progress of work may impact current period earnings through a cumulative adjustment. Additionally, if the EAC process indicates a loss, a provision is made for the total anticipated loss in the period that it becomes evident. Contract revenue and cost estimates for significant contracts are generally reviewed and reassessed at least quarterly. The cost-to-cost method is principally used to account for contracts in our Satellite and Space Communications segment and, to a lesser extent, certain location-based and messaging infrastructure contracts in our public safety and location technologies product line within our Terrestrial and Wireless Networks segment. For service-based contracts in our Terrestrial and Wireless Networks segment, we also recognize revenue over time. These services are typically recognized as a series of services performed over the contract term using the straight-line method, or based on our customers’ actual usage of the networks and platforms which we provide. • Point in time - When a performance obligation is not satisfied over time, we must record revenue using the point in time accounting method which generally results in revenue being recognized upon shipment or delivery of a promised good or service to a customer. This generally occurs when we enter into short term contracts or purchase orders where items are provided to customers with relatively quick turn-around times. Modifications to such contracts and/or purchase orders, which typically provide for additional quantities or services, are accounted for as a new contract because the pricing for these additional quantities or services are based on standalone selling prices. Point in time accounting is principally applied to contracts in our satellite ground station technologies product line (which includes satellite modem and traveling wave tube amplifiers). The contracts related to these product lines do not meet the requirements for over time revenue recognition because our customers cannot utilize the equipment for its intended purpose during any phase of our manufacturing process; customers do not simultaneously receive and/or consume the benefits provided by our performance; customers do not control the asset (i.e., prior to delivery, customers cannot direct the use of the asset, sell or exchange the equipment, etc.); and, although many of our contracts have termination for convenience clauses and/or an enforceable right to payment for performance completed to date, our performance creates an asset with an alternative use through the point of delivery. In determining that our equipment has alternative use, we considered the underlying manufacturing process for our products. In the early phases of manufacturing, raw materials and work in process (including subassemblies) consist of common parts that are highly fungible among many different types of products and customer applications. Finished products are either configured to our standard configuration or based on our customers’ specifications. Finished products, whether built to our standard specification or to a customers’ specification, can be sold to a variety of customers and across many different end use applications with minimal rework, if needed, and without incurring a significant economic loss. When identifying a contract with our customer, we consider when it has approval and commitment from both parties, if the rights of the parties are identified, if the payment terms are identified, if it has commercial substance and if collectability is probable. When identifying performance obligations, we consider whether there are multiple promises and how to account for them. In our contracts, multiple promises are separated if they are distinct, both individually and in the context of the contract. If multiple promises in a contract are highly interrelated or comprise a series of distinct services performed over time, they are combined into a single performance obligation. In some cases, we may also provide the customer with an additional service-type warranty, which we recognize as a separate performance obligation. Service-type warranties do not represent a significant portion of our consolidated net sales. When service-type warranties represent a separate performance obligation, the revenue is deferred and recognized ratably over the extended warranty period. Our contracts, from time-to-time, may also include options for additional goods and services. To date, these options have not represented material rights to the customer as the pricing for them reflects standalone selling prices. As a result, we do not consider options we offer to be performance obligations for which we must allocate a portion of the transaction price. In many cases, we provide assurance-type warranty coverage for some of our products for a period of at least one year from the date of delivery. When identifying the transaction price, we typically utilize the contract's stated price as a starting point. The transaction price in certain arrangements may include estimated amounts of variable consideration, including award fees, incentive fees or other provisions that can either increase or decrease the transaction price. We estimate variable consideration as the amount to which we expect to be entitled, and we include estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the estimation uncertainty is resolved. The estimation of this variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of our anticipated performance and all information (e.g., historical, current and forecasted) that is reasonably available to us. When allocating the contract’s transaction price, we consider each distinct performance obligation. For contracts with multiple performance obligations, we allocate the contract’s transaction price to each performance obligation using our best estimate of the standalone selling price of each distinct good or service in the contract. We determine standalone selling price based on the price at which the performance obligation is sold separately. If the standalone selling price is not observable through past transactions, we estimate the standalone selling price taking into account available information such as market conditions, including geographic or regional specific factors, competitive positioning, internal costs, profit objectives and internally approved pricing guidelines related to the performance obligations. Most of our contracts with customers are denominated in U.S. dollars and typically are either firm fixed-price or cost reimbursable type contracts (including fixed-fee, incentive-fee and time-and-material type contracts). In almost all of our contracts with customers, we are the principal in the arrangement and report revenue on a gross basis. Transaction prices for contracts with U.S. domestic and international customers are usually based on specific negotiations with each customer and in the case of the U.S. government, sometimes based on estimated or actual costs of providing the goods or services in accordance with applicable regulations. Sales by geography and customer type, as a percentage of consolidated net sales, are as follows: Fiscal Years Ended July 31, 2024 2023 2022 United States U.S. government 33.7 % 31.3 % 27.2 % Domestic 44.8 % 44.7 % 47.8 % Total United States 78.5 % 76.0 % 75.0 % International 21.5 % 24.0 % 25.0 % Total 100.0 % 100.0 % 100.0 % Sales to U.S. government customers include sales to the U.S. Department of Defense ("DoD"), intelligence and civilian agencies, as well as sales directly to or through prime contractors. Domestic sales include sales to commercial customers, as well as to U.S. state and local governments. For fiscal 2024, except for the U.S. government, there were no customers that represented more than 10% of consolidated net sales. For fiscal 2023 and 2022, included in domestic sales are sales to Verizon Communications Inc. ("Verizon"), which were 10.6% and 11.1% of consolidated net sales, respectively. International sales for fiscal 2024, 2023 and 2022 (which include sales to U.S. domestic companies for inclusion in products that are sold to international customers) were $115,924,000, $132,117,000 and $121,392,000, respectively. Except for the U.S., no individual country (including sales to U.S. domestic companies for inclusion in products that are sold to a foreign country) represented more than 10.0% of consolidated net sales for fiscal 2024, 2023 and 2022. The following tables summarize our disaggregation of revenue consistent with information reviewed by our Chief Operating Decision Maker ("CODM") for the fiscal years ended July 31, 2024, 2023 and 2022. We believe these categories best depict how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors which impact our business.

Under typical payment terms for our contracts accounted for over time, amounts are billed as work progresses in accordance with agreed-upon contractual terms, either at periodic intervals (e.g., monthly) or upon achievement of contractual milestones. For certain contracts with provisions that are intended to protect customers in the event we do not satisfy our performance obligations, billings occur subsequent to revenue recognition, resulting in unbilled receivables. Under ASC 606, unbilled receivables constitute contract assets. There were no material impairment losses recognized on contract assets during the fiscal years ended July 31, 2024, 2023 and 2022. On large long-term contracts, and for contracts with international customers that do not do business with us regularly, payment terms typically require advanced payments and deposits. Under ASC 606, payments received from customers in excess of revenue recognized to-date results in a contract liability. These contract liabilities are not considered to represent a significant financing component of the contract because we believe these cash advances and deposits are generally used to meet working capital demands which can be higher in the earlier stages of a contract. Also, advanced payments and deposits provide us with some measure of assurance that the customer will perform on its obligations under the contract. Under the typical payment terms for our contracts accounted for at a point in time, costs are accumulated in inventory until the time of billing, which generally coincides with revenue recognition. Of the current contract liability balance of $66,351,000 at July 31, 2023 and $64,601,000 at July 31, 2022, $48,902,000 and $53,079,000 was recognized as revenue during fiscal years 2024 and 2023, respectively. We recognize the incremental costs to obtain or fulfill a contract as an expense when incurred if the amortization period of the asset is one year or less; otherwise, such costs are capitalized and amortized over the estimated life of the contract. During fiscal year 2024, incremental costs to obtain or fulfill contracts with an amortization period greater than one year were $2,863,000. During fiscal year 2023, incremental costs to obtain or fulfill contracts with an amortization period greater than one year were not material. Commissions payable to our internal sales and marketing employees or contractors that are incremental to the acquisition of long-term customer contracts are capitalized and amortized consistent with the pattern of revenue recognition through cost of sales on our Consolidated Statements of Operations. Commissions payable that are not incremental to the acquisition of long-term contracts are expensed as incurred in selling, general and administrative expenses on our Consolidated Statements of Operations. As for commissions payable to our third-party sales representatives related to large long-term contracts, we consider these types of commissions both direct and incremental costs to obtain and fulfill such contracts. Therefore, such commissions are included in total estimated costs at completion for such contracts and expensed over time through cost of sales on our Consolidated Statements of Operations. Remaining performance obligations represent the transaction price of firm orders for which work has not been performed as of the end of a fiscal period. Remaining performance obligations, which we refer to as backlog, exclude unexercised contract options and potential orders under indefinite delivery / indefinite quantity ("IDIQ") contracts. As of July 31, 2024, the aggregate amount of the transaction price allocated to remaining performance obligations was $798,915,000 (which represents the amount of our consolidated funded backlog). We estimate that a substantial portion of our remaining performance obligations at July 31, 2024 will be completed and recognized as revenue during the next twenty-four month period, with the rest thereafter. During fiscal 2024, revenue recognized from performance obligations satisfied, or partially satisfied, in previous periods (for example due to changes in the transaction price) was not material. Cash and Cash Equivalents Our cash equivalents are short-term, highly liquid investments that are both readily convertible to known amounts of cash and have insignificant risk of change in value as a result of changes in interest rates. Our cash and cash equivalents, as of July 31, 2024 and 2023, amounted to $32,433,000 and $18,961,000, respectively, and primarily consist of bank deposits and money market deposit accounts insured by the Federal Deposit Insurance Corporation. Cash equivalents are carried at cost, which approximates fair value. At July 31, 2024, cash and cash equivalents includes $247,000 of cash deposited as collateral in connection with outstanding standby letters of credit to guarantee future performance on certain customer contracts. Inventories Our inventories are stated at the lower of cost and net realizable value, the latter of which is defined as the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. Our inventories are reduced to their estimated net realizable value by a charge to cost of sales in the period such excess costs are determined. Our inventories are principally recorded using either average or standard costing methods. Work-in-process (including our contracts-in-progress) and finished goods inventory reflect all accumulated production costs, which are comprised of direct production costs and overhead, and is reduced by amounts recorded in cost of sales as the related revenue is recognized. Indirect costs relating to long-term contracts, which include expenses such as general and administrative, are charged to expense as incurred and are not included in our cost of sales or work-in-process (including our contracts-in-progress) and finished goods inventory. Long-Lived Assets Our machinery and equipment, which are recorded at cost, are depreciated or amortized over their estimated useful lives (three to eight years) under the straight-line method. Capitalized internal use software costs are amortized once the software is placed in service under the straight-line method over the estimated useful life of the software, which is generally three years. Capitalized values of properties and leasehold improvements under l

Acquisitions	CEO Transition Costs For the three fiscal years ended July 31, 2024, cumulative CEO transition costs aggregated $25,560,000. Fiscal 2024 - On March 12, 2024, Ken Peterman, our former Chairman of the Board, President and CEO, was terminated for cause and the Board of Directors appointed John Ratigan as interim Chief Executive Officer ("CEO") and Mark Quinlan as Chairman of the Board of Directors. Prior to the changes, Mr. Ratigan served as our Chief Corporate Development Officer and Mr. Quinlan served as a member of our Board of Directors. Upon termination of his employment, Mr. Peterman was deemed to have resigned from his position as Chairman of the Board of Directors and as a director pursuant to his employment contract. CEO transition costs of $2,916,000 incurred during fiscal 2024 primarily consisted of legal expenses and were expensed in our Unallocated segment.

Credit Facility

Line of Credit Facility [Abstract]
Credit Facility	Credit Facility On November 30, 2022, we entered into a Second Amended and Restated Credit Agreement which provided a senior secured loan facility up to $300,000,000, consisting of (i) a revolving loan facility with a borrowing limit up to $150,000,000; and (ii) a $50,000,000 term loan. At July 31, 2023, the amount outstanding under the credit facility was $164,404,000, of which $160,029,000, net of deferred financing fees of $621,000, is reflected in the non-current portion of long-term debt on our Consolidated Balance Sheets. On Nov ember 7, 2023, we entered into a Third Amended and Restated Credit Agreement (the "Prior Credit Facility " ), which provided f or a senior secured loan facility of up to $200,000,000 consisting of: (i) a revolving loan facility with an initial borrowing limit of $150,000,000; and (ii) a $50,000,000 te rm loan . The Prior Credit Fac ility also provided for the following, among other things: effective January 31, 2024 and April 30, 2024, (a) our borrowing limit under the revolving loan facility reduced to $140,000,000 and $135,000,000, respectively; (b) the term loa n amortization increased from $1,250,000 to $1,875,000 per quarter, with the remaining balance due upon maturity; and (c) the Applicable Rate increased 0.25%. In connection with entering the Prior Credit Facility, we capitalized $5,941,000 of total financing costs and accounted for the amendments as debt modifications. On June 17, 2024, we entered into a $222,000,000 senior secured loan facility with a new syndicate of lenders (the “Credit Facility”), which replaced our Prior Credit Facility. The Credit Facility consists of: (i) a $162,000,000 term loan (the "Term Loan" facility) and an asset-based revolving credit facility with revolving commitments in an aggregate principal amount of $60,000,000, subject to borrowing base limitations as described below (the "Revolving Loan" facility). At closing, $25,000,000 of the Revolving Loan was funded and, together with the Term Loan, the proceeds were used to repay the Prior Credit Facility in full and for working capital and other general corporate purposes. The obligations under the Credit Facility are guaranteed by certain of our domestic and foreign subsidiaries (the “Guarantors), who have granted for the benefit of the lenders, a lien on, and first priority security interest in, substantially all of our tangible and intangible assets. The Credit Facility, which was amended October 17, 2024, has a maturity date which is the earlier of (x) July 31, 2028 or (y) 90 days prior to the earliest date that the debt under the Subordinated Credit Facility becomes due and payable (the "Maturity Date"), as discussed further below. In connection with entering the Credit Facility, the Term Loan lenders received 1,435,884 detachable warrants ("Lender warrants") granted at an exercise price of $0.10 per common share which entitles the Term Loan lenders to purchase 1,435,884 shares of our common stock from us at any time and from time to time after the Closing Date and on or prior to June 17, 2031, subject to certain adjustments. If the Term Loan is refinanced, the Term Loan lenders have the right to sell up to 50.0% of the warrants back to us for cash, at a 10.0% discount to the 30-day volume weighted average price of our common stock, subject to certain adjustments. We determined that the Lender warrants met the definition of a freestanding financial instrument that should be accounted for as a liability. We established an initial Lender warrant liability of $3,011,000 which was allocated as a discount against the Term Loan proceeds. The Lender warrant liability is classified in "Other Liabilities" on the Consolidated Balance Sheets and is remeasured to its estimated fair value each reporting period, using Level 3 fair value inputs, until the Lender warrants are exercised or expire. Changes in the estimated fair value of the Lender warrant liability are recognized in our Consolidated Statement of Operations as a non-cash expense or benefit. As of July 31, 2024, the Lender warrant liability was remeasured to $4,544,000, resulting in a non-cash expense of $1,533,000 recorded in "Other expenses (income)" on the Consolidated Statements of Operations . Additionally, we identified several embedded derivatives that require bifurcation from the Credit Facility under ASC 815-40 "Derivatives and Hedging - Contracts in Entity's Own Equity." Certain of these embedded features include events of default and contingent fee and interest rate increases and were determined to qualify as embedded derivatives, accounted for as one compound embedded derivative liability. We established an initial embedded derivative liability of $3,116,000, which was allocated as a discount against the Term Loan proceeds. The embedded derivative liability is classified in "Other Liabilities" on the Consolidated Balance Sheets and is remeasured to its estimated fair value each reporting period, using Level 3 fair value inputs, until the embedded derivative features have zero probability of occurring or expire. Changes in the estimated fair value of the embedded derivative liability are recognized in our Consolidated Statement of Operations as a non-cash expense or benefit. As of July 31, 2024, the embedded derivative liability was remeasured to $3,041,000, resulting in $75,000 of income recorded in " Other expenses (income) " on the Consolidated Statements of Operations . In connection with entering the Credit Facility, we paid fees of $15,035,000, including: (i) $9,979,000 of financing fees, of which $6,626,000 is attributable to the Term Loan and $3,353,000 is attributable to the Revolving Loan; and (ii) $5,056,000 of closing fees, representing approximately 3.0% of the Term Loan commitment plus certain other reimbursable expenses paid directly to the Term Loan lenders and accounted for as a discount against the Term Loan proceeds. Additionally, a $2,430,000 Term Loan exit fee, which was earned on the closing date and is payable directly to the Term Loan lenders at maturity or earlier, as defined, was accounted for as a discount against the Term Loan proceeds. The financing fees and discounts attributable to the Term Loan are amortized as interest expense over the life of the debt and are presented as a deduction to the borrowings outstanding under the Term Loan. The financing fees attributable to the Revolving Loan are capitalized on the Consolidated Balance Sheets and amortized as interest expense over the life of the debt. As of July 31, 2024, the amount outstanding under our Credit Facility was as follows: July 31, 2024 Term Loan $ 161,663,000 Less unamortized deferred financing costs related to Term Loan 6,425,000 Less unamortized discount related to Term Loan 13,202,000 Term Loan, net 142,036,000 Revolving Loan 32,500,000 Amount outstanding under Credit Facility, net 174,536,000 Less current portion of long-term debt 4,050,000 Non-current portion of long-term debt $ 170,486,000 During the fiscal year ended July 31, 2024, we had outstanding balances under our credit facilities ranging from $156,241,000 to $202,000,000. As of July 31, 2024, total net deferred financing costs related to the Credit Facility were $9,676,000 and are being amortized over the term of the Credit Facility through the Maturity Date. The refinancing of our Prior Credit Facility is considered a debt extinguishment and, as such, $1,832,000 of net deferred financing costs primarily related to the Prior Credit Facility were expensed in fiscal 2024 and included in interest expense reported on our Consolidated Statement of Operations . Interest expense related to our Credit Facility and Prior Credit Facility, including amortization of deferred financing costs and discounts, recorded during the fiscal years ended July 31, 2024, 2023 and 2022 was $22,058,000, $14,931,000 and $4,933,000, respectively. Our blended interest rate approximated 12.26%, 8.89% and 3.41% for fiscal 2024, 2023 and 2022, respectively. Availability under the Revolving Loan is subject to eligibility criteria set forth in the Credit Facility, and equal to a borrowing base in an amount equal to, from time to time: (a) 85% of the net book value of billed and invoiced accounts receivables of the Borrowing Base Parties, as defined; plus (b) 85% of the net book value of accounts receivables that the Borrowing Base Parties have the right to bill but have not yet billed up to the lesser of (i) 12.5% of the amount calculated pursuant to the sum of clauses (a) and (b) and (ii) $15.0 million of such accounts; plus (c) 60% of the net book value of all inventory of the Borrowing Base Parties, less (d) customary reserves. The Credit Facility provides that (a) Revolving Loans comprised of (i) Base Rate Loans shall bear interest at the Base Rate plus an additional margin ranging from 3.75% to 4.25%, depending on the average quarterly revolving loan usage during the applicable determination period and (ii) SOFR Loans shall bear interest at the Term SOFR rate plus an additional margin ranging from 4.75% to 5.25%, depending on the average quarterly revolving loan usage during the applicable determination period and (b) Term Loans comprised of (i) Base Rate Loans shall bear interest at the Base Rate plus an additional margin ranging from 7.50% to 9.00%, depending on our net leverage ratio during the applicable determination period and (ii) SOFR Loans shall bear interest at the Term SOFR rate plus an additional margin ranging from 8.50% to 10.00%, depending on our net leverage ratio during the applicable determination period. The Term Loans bear both cash interest and interest paid-in-kind ("PIK"). PIK interest is fixed at 2.50% and is to be capitalized and added to the outstanding principal on each interest payment date. The Term Loan is subject to 2.50% amortization per annum, payable on the last day of each fiscal quarter. The first Term Loan repayment of $675,000 was paid on July 31, 2024 and quarterly Term Loan repayments thereafter are $1,012,500, with the remaining Term Loan balance due on the Maturity Date. The Credit Facility contains (a) customary representations, warranties and affirmative covenants; (b) customary conditions to drawing the Revolver; (c) customary negative covenants, subject to negotiated exceptions, including but not limited to: (i) liens, (ii) investments, (iii) indebtedness, (iv) significant corporate changes, including mergers and acquisitions, (v) dispositions, including the disposition of assets by any Loan Party to any Subsidiary that is not a Subsidiary Loan Party, (vi) restricted payments, including stockholder dividends, (vii) distributions, including the repayment of subordinated intercompany and third party indebtedness, and (viii) certain other restrictive agreements; (d) certain financial covenants, including a maximum Net Leverage Ratio, minimum Fixed Charge Coverage Ratio, Minimum Average Liquidity and Minimum EBITDA; (e) customary optional and mandatory prepayment events; and (f) customary events of default (subject to grace periods, as appropriate), such as payment defaults, cross-defaults to other material indebtedness, bankruptcy and insolvency, the occurrence of a defined change in control and the failure to observe the negative covenants and other covenants related to the operation of our business. In addition, under certain circumstances, we may be required to enter into amendments to the Credit Facility in connection with any further syndication of the Credit Facility. Under the Credit Facility, for the trailing twelve months ("TTM") ended July 31, 2024, we were required to maintain a maximum Net Leverage Ratio of 3.25x TTM Adjusted EBITDA, a minimum Fixed Charge Coverage Ratio of 1.20x TTM Adjusted EBITDA and Minimum Average Liquidity of $20,000,000. As discussed below, on October 17, 2024, we entered into an amendment to the Credit Facility to waive a Net Leverage Ratio and Fixed Charge Coverage Ratio event of default as of July 31, 2024. Subsequent Event On October 17, 2024, we entered into an amendment to the Credit Facility (the “Amended Credit Facility”) in order to (i) waive certain events of default that occurred under the Credit Facility, including in connection with our Net Leverage Ratio and Fixed Charge Coverage Ratio for the 4 quarter period ended July 31, 2024. and (ii) amend the Credit Facility. As a result the Amended Credit Facility, there are no ongoing events of default under the Credit Facility. The Amended Credit Facility also amends the Credit Agreement to, amongst other things; (i) increase the interest rate margins applicable to the loans (as described in further detail below); (ii) modify certain financial and collateral reporting requirements; (iii) provide the lenders a consent right with respect to $27,500,000 of revolver borrowings above $32,500,000 (i.e., the current amount of revolver borrowings outstanding); (iv) permit the incurrence of $25,000,000 of senior unsecured subordinated debt (the "Subordinated Credit Agreement") (as described in further Note (19) – “Subsequent Event - Subordinated Credit Agreement” ); (v) amend the Maturity Date; and (vi) suspend financial covenant testing through the end of our fiscal quarter ending January 31, 2025. Under the Amended Credit Facility, the interest rate margins that are applicable to the Revolving Loan are increased by 1.00% at each level. Accordingly, the Amended Credit Facility provides that Revolving Loans comprised of (i) Base Rate Loans shall bear interest at the Base Rate plus an additional margin ranging from 4.75% to 5.25%; and (ii) SOFR Loans shall bear interest at the Term SOFR rate plus an additional margin ranging from 5.75% to 6.25%, each depending on the average quarterly revolving loan usage during the applicable determination period. The Amended Credit Facility provides that the interest rate margins on the Term Loans are 12.00% per annum for Base Rate Loans and 13.00% per annum for SOFR Loans until the first business day of the month following January 31, 2025, when the Company has delivered financial statements demonstrating compliance with the financial covenants under the Amended Credit Facility. If demonstrated, the interest rate margins revert to the margins provided under the Existing Credit Facility with respect to Term Loans, specifically, (i) Base Rate Loans shall bear interest at the Base Rate plus an additional margin ranging from 7.50% to 9.00%; and (ii) SOFR Loans shall bear interest at the Term SOFR rate plus an additional margin ranging from 8.50% to 10.00%, each depending on our Net Leverage Ratio during the applicable determination period. Capitalized terms used but not defined herein have the meanings set forth for such terms in the Prior Credit Facility, the Credit Facility and the Amended Credit Facility, all of which have been documented and filed with the SEC.

Leases

Leases	12 Months Ended

Leases [Abstract]
Leases	Leases Our leases historically relate to the leasing of facilities and equipment. In accordance with FASB ASC 842 - "Leases" ("ASC 842"), we determine at inception whether an arrangement is, or contains, a lease and whether the lease should be classified as an operating or a financing lease. At lease commencement, we recognize a right-of-use ("ROU") asset and lease liability based on the present value of the future lease payments over the estimated lease term. We have elected to not recognize a ROU asset or lease liability for any leases with terms of twelve months or less. Instead, for such short-term leases, we recognize lease expense on a straight-line basis over the lease term. Certain of our leases include options to extend the term of the lease or to terminate the lease early. When it is reasonably certain that we will exercise a renewal option or will not exercise a termination option, we include the impact of exercising or not exercising such option, respectively, in the estimate of the lease term. As our lease agreements do not explicitly state the discount rate implicit in the lease, we use our incremental borrowing rate ("IBR") on the commencement date to calculate the present value of future lease payments. Such IBR represents our estimated rate of interest to borrow on a collateralized basis over a term commensurate with the expected lease term. Some of our leases include payments that are based on the Consumer Price Index ("CPI") or other similar indices. These variable lease payments are included in the calculation of the ROU asset and lease liability using the index as of the lease commencement date. Other variable lease payments, such as common area maintenance, property taxes, and usage-based amounts, are required by ASC 842 to be excluded from the ROU asset and lease liability and expensed as incurred. In addition to the present value of the future lease payments, the calculation of the ROU asset would also consider, to the extent applicable, any deferred rent upon adoption, lease pre-payments or initial direct costs of obtaining the lease (e.g., such as commissions). For all classes of leased assets, we elected the practical expedient to not separate lease components (i.e., the actual item being leased, such as the facility or piece of equipment) from non-lease components (i.e., the distinct elements of a contract not related to securing the use of the leased asset, such as common area maintenance and consumable supplies). Certain of our facility lease agreements (which are classified as operating leases) contain rent holidays or rent escalation clauses. For rent holidays and rent escalation clauses during the lease term, we record rental expense on a straight-line basis over the term of the lease. As of July 31, 2024, none of our leases contained a residual value guarantee and covenants included in our lease agreements are customary for the types of facilities and equipment being leased. The components of lease expense are as follows: Fiscal years ended July 31, 2024 2023 2022 Finance lease expense: Amortization of ROU assets $ — 5,000 13,000 Interest on lease liabilities — — 1,000 Operating lease expense 8,414,000 10,439,000 11,658,000 Short-term lease expense 293,000 435,000 402,000 Variable lease expense 4,381,000 4,031,000 4,619,000 Sublease income (67,000) (67,000) (67,000) Total lease expense $ 13,021,000 14,843,000 16,626,000 Additional information related to leases is as follows: Fiscal years ended July 31, 2024 2023 2022 Cash paid for amounts included in the measurement of lease Operating leases - Operating cash outflows $ 8,983,000 10,604,000 11,864,000 Finance leases - Operating cash outflows — — 1,000 Finance leases - Financing cash outflows — 4,000 15,000 ROU assets obtained in the exchange for lease liabilities Operating leases $ 677,000 3,211,000 15,233,000 The following table is a reconciliation of future cash flows relating to operating lease liabilities presented on our Consolidated Balance Sheets as of July 31, 2024: Operating Fiscal 2025 $ 8,263,000 Fiscal 2026 6,857,000 Fiscal 2027 4,756,000 Fiscal 2028 4,019,000 Fiscal 2029 3,367,000 Thereafter 16,428,000 Total future undiscounted cash flows 43,690,000 Less: Present value discount 5,563,000 Lease liabilities $ 38,127,000 Weighted-average remaining lease terms (in years) 7.97 Weighted-average discount rate 3.54 % As of July 31, 2024, we do not have any material rental commitments that have not commenced.

Such IBR represents our estimated rate of interest to borrow on a collateralized basis over a term commensurate with the expected lease term. Some of our leases include payments that are based on the Consumer Price Index ("CPI") or other similar indices. These variable lease payments are included in the calculation of the ROU asset and lease liability using the index as of the lease commencement date. Other variable lease payments, such as common area maintenance, property taxes, and usage-based amounts, are required by ASC 842 to be excluded from the ROU asset and lease liability and expensed as incurred. In addition to the present value of the future lease payments, the calculation of the ROU asset would also consider, to the extent applicable, any deferred rent upon adoption, lease pre-payments or initial direct costs of obtaining the lease (e.g., such as commissions). For all classes of leased assets, we elected the practical expedient to not separate lease components (i.e., the actual item being leased, such as the facility or piece of equipment) from non-lease components (i.e., the distinct elements of a contract not related to securing the use of the leased asset, such as common area maintenance and consumable supplies). Certain of our facility lease agreements (which are classified as operating leases) contain rent holidays or rent escalation clauses. For rent holidays and rent escalation clauses during the lease term, we record rental expense on a straight-line basis over the term of the lease. As of July 31, 2024, none of our leases contained a residual value guarantee and covenants included in our lease agreements are customary for the types of facilities and equipment being leased. The components of lease expense are as follows: Fiscal years ended July 31, 2024 2023 2022 Finance lease expense: Amortization of ROU assets $ — 5,000 13,000 Interest on lease liabilities — — 1,000 Operating lease expense 8,414,000 10,439,000 11,658,000 Short-term lease expense 293,000 435,000 402,000 Variable lease expense 4,381,000 4,031,000 4,619,000 Sublease income (67,000) (67,000) (67,000) Total lease expense $ 13,021,000 14,843,000 16,626,000 Additional information related to leases is as follows: Fiscal years ended July 31, 2024 2023 2022 Cash paid for amounts included in the measurement of lease Operating leases - Operating cash outflows $ 8,983,000 10,604,000 11,864,000 Finance leases - Operating cash outflows — — 1,000 Finance leases - Financing cash outflows — 4,000 15,000 ROU assets obtained in the exchange for lease liabilities Operating leases $ 677,000 3,211,000 15,233,000 The following table is a reconciliation of future cash flows relating to operating lease liabilities presented on our Consolidated Balance Sheets as of July 31, 2024: Operating Fiscal 2025 $ 8,263,000 Fiscal 2026 6,857,000 Fiscal 2027 4,756,000 Fiscal 2028 4,019,000 Fiscal 2029 3,367,000 Thereafter 16,428,000 Total future undiscounted cash flows 43,690,000 Less: Present value discount 5,563,000 Lease liabilities $ 38,127,000 Weighted-average remaining lease terms (in years) 7.97 Weighted-average discount rate 3.54 % As of July 31, 2024, we do not have any material rental commitments that have not commenced.

At July 31, 2023, our net deferred tax liability of $8,903,000 includes $591,000 of foreign net deferred tax assets that were recorded as other assets, net in our Consolidated Balance Sheets. We account for income taxes pursuant to ASC 740, which requires an asset and liability based approach in accounting for income taxes. In assessing the realizability of deferred tax assets, management considers whether it is more-likely-than-not that some portion or all of them will not be realized. If management determines that it is more-likely-than-not that some or all of its deferred tax assets will not be realized, a valuation allowance will be recorded against such deferred tax assets. At July 31, 2024, we have federal research and experimentation credits carryforwards of $7,991,000 which begin to expire in 2033. We have state research and experimentation credit carryforwards of $9,234,000 which begin to expire in 2025. We believe that it is more-likely-than-not that the benefit from certain state research and experimentation credits will not be realized. In recognition of this risk, we have provided a valuation allowance of $8,502,000 on the deferred tax assets relating to these state credits. At July 31, 2024, we have a nominal amount of federal net operating loss carryforwards which begin to expire in 2038. We have state net operating loss carryforwards of $3,652,000 which begin to expire in 2025. We believe it to be more-likely-than-not that the benefit from certain state net operating loss carryforwards will not be realized. In recognition of this risk, we have provided a valuation allowance of $3,448,000 on the deferred tax assets relating to these state net operating loss carryforwards. At July 31, 2024, we have federal and state capital loss carryforwards of $14,473,000 which mostly expire in 2026. We believe it to be more-likely-than-not that the benefit from these federal and state capital loss carryforwards will not be realized. In recognition of this risk, we have provided a full valuation allowance on the deferred tax assets relating to these federal and state capital loss carryforwards. With respect to our remaining U.S. federal and state net deferred tax assets as of July 31, 2024, we believe it to be more-likely-than-not that the benefit from such assets will not be realized. In recognition of this risk, we have provided a valuation allowance of $2,799,000 on these net deferred tax assets. At July 31, 2024, we have foreign deferred tax assets relating to research and experimentation credits of $335,000 which begin to expire in 2039. We have foreign deferred tax assets relating to net operating loss carryforwards of $14,624,000 which begin to expire in 2032. We believe that it is more-likely-than-not that certain foreign deferred tax assets, which include these net operating loss carryforwards, may not be realized. In recognition of this risk, we have provided a valuation allowance of $15,666,000 on these deferred tax assets. Our foreign earnings and profits are not material and, as such, we have not recorded any deferred tax liability on unremitted foreign earnings. At July 31, 2024 and 2023, total unrecognized tax benefits were $8,605,000 and $9,166,000, respectively, including interest of $224,000 and $210,000, respectively. At July 31, 2024 and 2023, $2,231,000 and $2,208,000, respectively, of our unrecognized tax benefits were recorded as non-current income taxes payable on our Consolidated Balance Sheets. The remaining unrecognized tax benefits of $6,374,000 and $6,958,000 at July 31, 2024 and 2023, respectively, were presented as an offset to the associated non-current deferred tax assets on our Consolidated Balance Sheets. Of the total unrecognized tax benefits, $7,679,000 and $8,286,000 at July 31, 2024 and 2023, respectively, net of the reversal of the federal benefit recognized as a deferred tax asset relating to state reserves, would favorably impact our effective tax rate, if recognized. We believe it is reasonably possible that the gross unrecognized tax benefits could decrease by as much as $512,000 in the next 12 months due to the expiration of statute of limitations related to federal, state and foreign tax positions. Our policy is to recognize potential interest and penalties relating to uncertain tax positions in income tax expense. The following table summarizes the activity related to our unrecognized tax benefits for fiscal years 2024, 2023 and 2022 (excluding interest): 2024 2023 2022 Balance at beginning of period $ 8,956,000 9,675,000 9,009,000 Increase related to current period 181,000 681,000 598,000 Increase related to prior periods 130,000 51,000 153,000 Expiration of statute of limitations (622,000) (1,406,000) (83,000) Decrease related to prior periods (264,000) (45,000) (2,000) Balance at end of period $ 8,381,000 8,956,000 9,675,000 Our U.S. federal income tax returns for fiscal 2021 through 2023 are subject to potential future Internal Revenue Service ("IRS") audit. None of our state income tax returns prior to fiscal 2020 are subject to audit. Future tax assessments or settlements could have a material adverse effect on our consolidated results of operations and financial condition.

Stock-Based Compensation

Stock-Based Compensation	12 Months Ended
	Jul. 31, 2024
Share-Based Payment Arrangement [Abstract]
Stock-Based Compensation	Stock-Based Compensation Overview In December 2023, our stockholders approved the Comtech Telecommunications Corp. 2023 Equity and Incentive Plan (the “2023 Plan”). The 2023 Plan replaced the Comtech Telecommunications Corp. Amended and Restated 2000 Stock Incentive Plan (the "Prior Plan" and collectively, the "Plans"). Under the 2023 Plan, the number of shares of common stock initially available for all awards, other than substitute awards granted in connection with a corporate transaction, will be (i) 1,600,000 shares plus (ii) 69,683 shares of common stock that were available for awards under the Prior Plan, as of the effective date of the 2023 Plan and (iii) certain expired or cancelled awards recycled back into the 2023 Plan. We issue stock-based awards to certain of our employees and our Board of Directors pursuant to the 2023 Plan, as amended and/or restated from time to time and our 2001 Employee Stock Purchase Plan, as amended and/or restated from time to time (the "ESPP"), and recognize related stock-based compensation in our consolidated financial statements. The 2023 Plan provides for the granting to employees and consultants of Comtech (including prospective employees and consultants): (i) incentive and non-qualified stock options, (ii) restricted stock units ("RSUs"), (iii) RSUs with performance measures (which we refer to as "performance shares"), (iv) restricted stock, (v) stock units (reserved for issuance to non-employee directors) and share units (reserved for issuance to employees) (collectively, "share units") and (vi) stock appreciation rights ("SARs"), among other types of awards. Our non-employee directors are eligible to receive non-discretionary grants of stock-based awards, subject to certain limitations. As of July 31, 2024, the aggregate number of shares of common stock which may be issued, pursuant to the Plan, may not exceed 13,562,500. Stock options granted may not have a term exceeding ten years or, in the case of an incentive stock award granted to a stockholder who owns stock representing more than 10.0% of the voting power, no more than five years. We expect to settle all outstanding awards under the Plan and employee purchases under the ESPP with the issuance of new shares of our common stock. As of July 31, 2024, we had granted stock-based awards pursuant to the Plan representing the right to purchase and/or acquire an aggregate of 11,468,463 shares (net of 6,679,364 expired and canceled awards), of which an aggregate of 9,526,985 have been exercised or settled. As of July 31, 2024, the following stock-based awards, by award type, were outstanding: July 31, 2024 Stock options 141,190 Performance shares 380,680 RSUs, restricted stock, share units and other stock-based awards 1,419,608 Total 1,941,478 Our ESPP provides for the issuance of up to 1,300,000 shares of our common stock. Our ESPP is intended to provide our eligible employees the opportunity to acquire our common stock at 85% of fair market value on the first or last day of each calendar quarter, whichever is lower. Through July 31, 2024, we have cumulatively issued 1,051,110 shares of our common stock to participating employees in connection with our ESPP. Stock-based compensation for awards issued is reflected in the following line items in our Consolidated Statements of Operations: Fiscal Years Ended July 31, 2024 2023 2022 Cost of sales $ 778,000 1,110,000 692,000 Selling, general and administrative expenses 4,777,000 7,960,000 6,312,000 Research and development expenses 541,000 1,037,000 763,000 Stock-based compensation expense before CEO transition 6,096,000 10,107,000 7,767,000 CEO transition costs related to equity-classified stock-based — 3,764,000 7,388,000 Total stock-based compensation expense before income tax benefit 6,096,000 13,871,000 15,155,000 Estimated income tax benefit (1,298,000) (2,552,000) (2,260,000) Net stock-based compensation expense $ 4,798,000 11,319,000 12,895,000 Stock-based compensation for equity-classified awards is measured at the date of grant, based on an estimate of the fair value of the award and is generally expensed over the vesting period of the award. At July 31, 2024, unrecognized stock-based compensation of $6,183,000, net of estimated forfeitures of $687,000, is expected to be recognized over a weighted average period of 1.9 years. Total stock-based compensation capitalized and included in ending inventory at both July 31, 2024 and 2023 was $198,000. There are no liability-classified stock-based awards outstanding as of July 31, 2024 or 2023. Selling, general and administrative expenses included in the table above, for fiscal 2022, includes $827,000 of amortization of stock-based compensation related to three, long-standing members of our Board of Directors who retired in December 2021. Stock-based compensation expense, by award type, is summarized as follows: Fiscal Years Ended July 31, 2024 2023 2022 Stock options $ 60,000 87,000 519,000 Performance shares 480,000 973,000 1,136,000 RSUs, restricted stock, share units and other stock-based awards 5,477,000 8,926,000 5,912,000 ESPP 79,000 121,000 200,000 Stock based compensation expense before CEO transition costs 6,096,000 10,107,000 7,767,000 CEO transition costs related to equity-classified stock-based — 3,764,000 7,388,000 Total stock-based compensation expense before income tax benefit 6,096,000 13,871,000 15,155,000 Estimated income tax benefit (1,298,000) (2,552,000) (2,260,000) Net stock-based compensation expense $ 4,798,000 11,319,000 12,895,000 In connection with the March 12, 2024 termination of our former CEO for cause, a combined total of 581,021 performance shares and RSUs were cancelled. ESPP stock-based compensation expense primarily relates to the 15% discount offered to participants in the ESPP. The estimated income tax benefit as shown in the above table was computed using income tax rates expected to apply when the awards are settled. Such deferred tax asset was recorded net as part of our non-current deferred tax liability on our Consolidated Balance Sheet as of July 31, 2024 and 2023. The actual income tax benefit recognized for tax reporting is based on the fair market value of our common stock at the time of settlement and can significantly differ from the estimated income tax benefit recorded for financial reporting. Stock Options The following table summarizes the Plan's activity: Awards Weighted Average Weighted Average Aggregate Outstanding at July 31, 2021 1,073,435 $ 25.76 Expired/canceled (588,735) 26.86 Exercised (1,220) 17.88 Outstanding at July 31, 2022 483,480 24.43 Expired/canceled (242,970) 24.89 Outstanding at July 31, 2023 240,510 23.96 Expired/canceled (99,320) 28.72 Outstanding at July 31, 2024 141,190 $ 20.61 4.51 $ — Exercisable at July 31, 2024 129,840 $ 20.84 4.39 $ — Vested and expected to vest at July 31, 2024 139,975 $ 20.63 4.50 $ — Stock options outstanding as of July 31, 2024 have exercise prices ranging from $17.88 - $28.35, representing the fair market value of our common stock on the date of grant, a contractual term of ten years and a vesting period of five years. The total intrinsic value relating to stock options exercised during the fiscal year ended July 31 2022 was $7,000. There were no stock options exercised during the fiscal years ended July 31, 2024 and 2023. During fiscal 2022, at the election of certain holders of vested stock options, 1,220 stock options were net settled upon exercise. As a result, 220 shares of our common stock were issued during the fiscal year ended July 31, 2022, net of shares retained to satisfy the exercise price and minimum statutory tax withholding requirements. There were no stock options granted during fiscal years ended July 31, 2024, 2023 or 2022. Performance Shares, RSUs, Restricted Stock, Share Unit Awards and Other Stock-based Awards The following table summarizes the Plan's activity relating to performance shares, RSUs, restricted stock, share units and other stock-based awards: Awards Weighted Average Aggregate Intrinsic Value Outstanding at July 31, 2021 1,068,370 $ 21.93 Granted 797,771 18.77 Settled (641,747) 22.83 Canceled/Forfeited (113,644) 22.78 Outstanding at July 31, 2022 1,110,750 19.05 Granted 1,550,951 10.79 Settled (632,267) 16.69 Canceled/Forfeited (153,204) 16.67 Outstanding at July 31, 2023 1,876,230 13.21 Granted 1,731,760 6.71 Settled (1,042,860) 9.77 Canceled/Forfeited (764,842) 9.28 Outstanding at July 31, 2024 1,800,288 $ 10.61 $ 5,833,000 Vested at July 31, 2024 583,209 $ 12.30 $ 1,890,000 Vested and expected to vest at July 31, 2024 1,739,662 $ 10.61 $ 5,637,000 The total intrinsic value relating to fully-vested awards settled during the fiscal years ended July 31, 2024, 2023 and 2022 was $7,844,000, $6,782,000 and $12,560,000, respectively. The performance shares granted to employees principally vest over a three-year performance period, if pre-established performance goals are attained, or as specified pursuant to the Plan and related agreements. As of July 31, 2024, the number of outstanding performance shares included in the above table, and the related compensation expense prior to consideration of estimated pre-vesting forfeitures, assume achievement of the pre-established goals at a target level, except for two of our former CEO's, whose achievement was based on maximum performance pursuant to their pre-existing change-in-control agreements. RSUs and restricted stock granted to non-employee directors prior to August 2022 had a vesting period of five years and were convertible into shares of our common stock generally at the time of termination, on a one-for-one basis for no cash consideration, or earlier under certain circumstances. Commencing in August 2022, such awards have a vesting period of one year. RSUs granted to employees prior to August 2022 have a vesting period of five years and are convertible into shares of our common stock generally at the time of vesting, on a one-for-one basis for no cash consideration. Commencing in August 2022, such RSUs have a vesting period of three years. Share units granted prior to July 31, 2017 were vested when issued and are convertible into shares of our common stock, generally at the time of termination, on a one-for-one basis for no cash consideration, or earlier under certain circumstances. Share units granted on or after July 31, 2017 were granted to certain employees in lieu of non-equity incentive compensation and are convertible into shares of our common stock on the one-year anniversary of the respective grant date. In July 2024 and 2023, we granted shares of our common stock to certain employees in lieu of non-equity incentive compensation. On July 31, 2024, 479,257 other stock-based awards were granted to certain employees in lieu of fiscal 2024 non-equity incentive compensation. Also, on July 27, 2024, 243,098 fully vested share units (previously granted in lieu of fiscal 2023 non-equity incentive compensation) were settled by delivery of 158,941 shares of our common stock after reduction of share units retained to satisfy employees’ statutory tax withholding requirements. Cumulatively, through July 31, 2024, 2,147,701 share units and other stock-based awards granted have been settled. The fair value of performance shares, RSUs, restricted stock, share units and other stock-based awards is determined using the closing market price of our common stock on the date of grant, less the present value of any estimated future dividend equivalents such awards are not entitled to receive and an applicable estimated discount for any post-vesting transfer restrictions. RSUs, performance shares and restricted stock are entitled to dividend equivalents, as applicable, unless forfeited before vesting occurs. Share units and other stock-based awards would be entitled to dividend equivalents while the underlying shares are unissued. Dividend equivalents are subject to forfeiture, similar to the terms of the underlying stock-based awards, and are payable in cash generally at the time of settlement of the underlying award. During fiscal 2024, we reversed $107,000 of previously accrued dividend equivalents due to forfeitures and paid out $268,000. During fiscal 2023 and 2022, we accrued $315,000 and $389,000, respectively, of dividend equivalents (net of forfeitures) and paid out $366,000 and $531,000, respectively. Accrued dividend equivalents were recorded as a reduction to retained earnings. As of July 31, 2024 and 2023, accrued dividend equivalents were $316,000 and $691,000, respectively. With respect to the actual settlement of stock-based awards for income tax reporting, during the fiscal years ended July 31, 2024, 2023 and 2022, we recorded an income tax expense of $723,000, $591,000 and $924,000, respectively. Subsequent Events In the first quarter of fiscal 2025, our Board of Directors authorized the issuance of stock-based awards with a total unrecognized compensation expense, net of estimated forfeitures, of approximately $6,700,000.

Segment Reporting [Abstract]
Segment Information	Segment Information Reportable operating segments are determined based on Comtech’s management approach. The management approach, as defined by FASB ASC 280 "Segment Reporting" is based on the way that the CODM organizes the segments within an enterprise for making decisions about resources to be allocated and assessing their performance. Our CODM, for purposes of FASB ASC 280, is our Chief Executive Officer. Satellite and Space Communications is organized into is organized into four technology areas: satellite modem and amplifier technologies, troposcatter technologies, government services and space components. This segment offers customers: satellite ground station technologies, services and system integration that facilitate the transmission of voice, video and data over GEO, MEO and LEO satellite constellations, including traveling wave tube power amplifiers, modems, VSAT platforms and frequency converters; over-the-horizon microwave solutions that can transmit digitized voice, video, and data over distances up to 200 miles using the troposphere and diffraction; professional engineering, training and field support services, including cybersecurity, for multiple U.S. government agencies; and procurement and supply chain management of high reliability Electrical, Electronic and Electromechanical ("EEE") parts for satellite, launch vehicle and manned space applications. Terrestrial and Wireless Networks is organized into three service areas: next generation 911 and call delivery, Solacom call handling solutions, and trusted location and messaging solutions. This segment offers customers: Wireless/VolP 911 location and routing services to connect emergency calls to Public Safety Answering Points ("PSAPs"); SMS text to 911 services, providing alternate paths for individuals who need to request assistance (via text messaging) a method to reach PSAPs; next generation 911 solutions, providing emergency call routing, location validation, policy-based routing rules, logging and security functionality; Emergency Services IP Network transport infrastructure for emergency services communications and support of next generation 911 services; call handling applications for PSAPs; wireless emergency alerts solutions for network operators; and software and equipment for location-based and text messaging services for various applications, including for public safety, commercial and government services. Our CODM primarily uses a metric that we refer to as Adjusted EBITDA to measure an operating segment’s performance and to make decisions about resources to be allocated. Our Adjusted EBITDA metric for the Satellite and Space Communications and Terrestrial and Wireless Networks segments do not consider allocation of any indirect expenses that are unrelated to the segment's operations, or any of the following: income taxes, interest, change in fair value of the convertible preferred stock purchase option liability, change in fair value of warrants, write-off of deferred financing costs, amortization of stock-based compensation, amortization of intangibles, depreciation expense, amortization of cost to fulfill assets, acquisition plan expenses, restructuring costs, COVID-19 related costs, strategic emerging technology costs (for next-generation satellite technology), facility exit costs, CEO transition costs, proxy solicitation costs, strategic alternatives expenses and other. These items, while periodically affecting our results, may vary significantly from period to period and may have a disproportionate effect in a given period, thereby affecting the comparability of results. Any amounts shown in the Adjusted EBITDA calculation for our Satellite and Space Communications and Terrestrial and Wireless Networks segments are directly attributable to those segments. Our Adjusted EBITDA is also used by our management in assessing the Company's operating results. Although closely aligned, the Company's definition of Adjusted EBITDA is different than the Consolidated EBITDA or EBITDA (as such terms are defined in our Prior Credit Facility and Credit Facility) utilized for financial covenant calculations and also 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. Operating segment information, along with a reconciliation of segment net income (loss) and consolidated net income (loss) to Adjusted EBITDA is presented in the tables below: Fiscal Year Ended July 31, 2024 Satellite and Space Communications Terrestrial and Wireless Networks Unallocated Total Net sales $ 324,069,000 216,334,000 — $ 540,403,000 Operating (loss) income $ (54,202,000) 21,670,000 (47,358,000) $ (79,890,000) Net (loss) income $ (55,491,000) 20,955,000 (65,449,000) $ (99,985,000) Provision for (benefit from) income taxes 666,000 669,000 (1,630,000) (295,000) Interest expense 25,000 — 22,128,000 22,153,000 Interest (income) and other 598,000 46,000 34,000 678,000 Write-off of deferred financing costs — — 1,832,000 1,832,000 Change in fair value of warrants and — — (4,273,000) (4,273,000) Amortization of stock-based compensation — — 6,096,000 6,096,000 Amortization of intangibles 6,685,000 14,469,000 — 21,154,000 Depreciation 3,867,000 7,927,000 365,000 12,159,000 Impairment of long-lived assets, including 64,525,000 — — 64,525,000 Amortization of cost to fulfill assets 960,000 — — 960,000 CEO transition costs — — 2,916,000 2,916,000 Restructuring costs 3,822,000 605,000 8,043,000 12,470,000 Strategic emerging technology costs 4,110,000 — — 4,110,000 Loss on business divestiture — — 1,199,000 1,199,000 Adjusted EBITDA $ 29,767,000 44,671,000 (28,739,000) $ 45,699,000 Purchases of property, plant and equipment $ 2,890,000 8,569,000 1,624,000 $ 13,083,000 Total assets at July 31, 2024 $ 421,780,000 456,425,000 34,229,000 $ 912,434,000 Fiscal Year Ended July 31, 2023 Satellite and Space Communications Terrestrial and Wireless Networks Unallocated Total Net sales $ 337,756,000 212,238,000 — $ 549,994,000 Operating income (loss) $ 15,041,000 12,323,000 (42,024,000) $ (14,660,000) Net income (loss) $ 15,539,000 12,297,000 (54,735,000) $ (26,899,000) Benefit from income taxes (1,724,000) (193,000) (2,031,000) (3,948,000) Interest expense 2,000 — 14,959,000 14,961,000 Interest (income) and other 1,224,000 219,000 (217,000) 1,226,000 Amortization of stock-based compensation — — 10,107,000 10,107,000 Amortization of intangibles 7,312,000 14,084,000 — 21,396,000 Depreciation 4,121,000 7,637,000 164,000 11,922,000 Amortization of cost to fulfill assets 959,000 — — 959,000 Restructuring costs 5,725,000 1,220,000 3,907,000 10,852,000 Strategic emerging technology costs 3,833,000 — — 3,833,000 CEO transition costs — — 9,090,000 9,090,000 Adjusted EBITDA $ 36,991,000 35,264,000 (18,756,000) $ 53,499,000 Purchases of property, plant and equipment $ 7,244,000 10,075,000 992,000 $ 18,311,000 Total assets at July 31, 2023 $ 515,449,000 460,034,000 20,754,000 $ 996,237,000 Fiscal Year Ended July 31, 2022 Satellite and Space Communications Terrestrial and Wireless Networks Unallocated Total Net sales $ 279,678,000 206,561,000 — $ 486,239,000 Operating (loss) income $ (5,671,000) 18,925,000 (47,006,000) $ (33,752,000) Net (loss) income $ (3,852,000) 18,796,000 (47,996,000) $ (33,052,000) (Benefit from) provision for income taxes (1,120,000) 19,000 (2,922,000) (4,023,000) Interest expense 98,000 — 4,933,000 5,031,000 Interest (income) and other (797,000) 110,000 (16,000) (703,000) Change in fair value of convertible — — (1,005,000) (1,005,000) Amortization of stock-based compensation — — 7,767,000 7,767,000 Amortization of intangibles 7,312,000 14,084,000 — 21,396,000 Depreciation 4,049,000 6,069,000 196,000 10,314,000 Amortization of cost to fulfill assets 469,000 — — 469,000 Restructuring costs 5,666,000 — 299,000 5,965,000 COVID-19 related costs 1,105,000 — — $ 1,105,000 Strategic emerging technology costs 1,197,000 — — $ 1,197,000 CEO transition costs — — 13,554,000 13,554,000 Proxy solicitation costs — — 11,248,000 11,248,000 Adjusted EBITDA $ 14,127,000 39,078,000 (13,942,000) $ 39,263,000 Purchases of property, plant and equipment $ 8,915,000 10,704,000 — $ 19,619,000 Total assets at July 31, 2022 $ 487,235,000 461,443,000 25,619,000 $ 974,297,000 Unallocated expenses result from corporate expenses such as executive compensation, accounting, legal and other regulatory compliance related costs and also includes all of our amortization of stock-based compensation. See Note (2) - " CEO Transition Costs " for information related to such costs. During fiscal 2024, our Unallocated segment incurred $8,043,000 of restructuring costs focused on: (i) streamlining our operations and supply chain, (ii) legal and other expenses primarily related to divestiture activities, and (iii) efforts to refinance our Prior Credit Facility and improve liquidity. During fiscal 2023, we incurred $3,907,000 of restructuring costs focused on streamlining our operations. During fiscal 2022, we incurred $11,248,000 of proxy solicitation costs (including legal and advisory fees and costs associated with a related lawsuit) as a result of a now-settled proxy contest and expensed $13,554,000 of transition costs related to the former CEO, Fred Kornberg. During fiscal 2024, 2023 and 2022, our Satellite and Space Communications segment recorded $3,822,000, $5,725,000 and $5,666,000, respectively, of restructuring costs primarily incurred to streamline our operations and improve efficiency, including costs related to the relocation of certain of our satellite ground station production facilities to our new 146,000 square foot facility in Chandler, Arizona. In addition, during fiscal 2024, 2023 and 2022, we incurred $4,110,000, $3,833,000 and $1,197,000, respectively, of strategic emerging technology costs for next-generation satellite technology to advance our solutions offerings to be used with new broadband satellite constellations. Furthermore, during fiscal 2022, this segment recorded $1,105,000 of incremental operating costs related to our antenna facility located in the United Kingdom due to the impact of the COVID-19 pandemic. There were no similar incremental operating costs recorded in fiscal 2024 or 2023. Interest expense in the tables above primarily relates to our Credit Facility, and includes the amortization of deferred financing costs. See Note (8) - " Credit Facility " for further discussion. Intersegment sales in fiscal 2024, 2023 and 2022 between the Satellite and Space Communications segment and the Terrestrial and Wireless Networks segment were nominal. All intersegment sales are eliminated in consolidation and are excluded from the tables above. Unallocated assets at July 31, 2024 consist principally of cash and cash equivalents, income taxes receivable, corporate property, plant and equipment and deferred financing costs. The large majority of our long-lived assets are located in the U.S.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies (a) Legal Proceedings and Other Matters Other Matters In the ordinary course of business, we include indemnification provisions in certain of our customer contracts to indemnify, hold harmless and reimburse such customers for certain losses, including but not limited to losses related to third-party claims of intellectual property infringement arising from the customer’s use of our products or services. We may also, from time to time, receive indemnification requests from customers related to third-party claims that 911 calls were improperly routed during an emergency. We evaluate such claims as and when they arise. We do not always agree with customers that they are entitled to indemnification and in such cases reject their claims. Despite maintaining that we have properly carried out our duties, we may seek coverage under our various insurance policies; however, we cannot be sure that we will be able to maintain or obtain insurance coverage at acceptable costs or in sufficient amounts or that our insurer will not disclaim coverage as to such claims. Accordingly, pending or future claims asserted against us by a party that we are obligated to indemnify could result in legal costs and damages that could have a material adverse effect on our consolidated results of operations and financial condition. There are certain other pending and threatened legal actions which arise in the normal course of business, in addition to certain matters related to the termination of our former CEO for cause in March 2024. Although the ultimate outcome of these matters is difficult to accurately predict, we believe that the outcome of these other matters will not have a material adverse effect on our consolidated financial condition or results of operations. (b) Employment Change of Control and Indemnification Agreements As of July 31, 2023, we had an employment agreement with Ken Peterman, our former Chairman of the Board, President and CEO, which was entered into on August 9, 2022. The employment agreement generally provided for an annual salary, bonus award, sign-on bonus, equity incentive awards and, under certain termination of employment, severance payment. On March 12, 2024, we announced the termination of Mr. Peterman for cause and upon termination of his employment, Mr. Peterman was deemed to have resigned from his position as Chairman of the Board of Directors and as a director pursuant to his employment contract. As of July 31, 2022, we had an employment agreement with Michael Porcelain, our former President and CEO. The employment agreement generally provided for an annual salary and bonus award. On August 10, 2022, we announced the mutually agreed separation between the Company and Mr. Porcelain as President and CEO and member of the Board of Directors. The Company entered into a separation agreement with Mr. Porcelain. Fiscal 2024 transition costs of $2,916,000 primarily consisted of legal expenses associated with the termination of Mr. Peterman. In fiscal 2023 transition costs related to Mr. Porcelain, pursuant to his separation agreement with the Company, were approximately $7,424,000, of which $3,764,000 related to the acceleration of unamortized stock-based compensation, with the remaining $3,660,000 related to his severance payments and benefits upon termination of employment. The cash portion of the transition costs of $3,660,000 was paid to Mr. Porcelain in October 2022. Also in fiscal 2023, in connection with Mr. Peterman entering into an employment agreement with the Company, effective as of August 9, 2022, we incurred a $1,000,000 expense related to a cash sign-on bonus. CEO transition costs related to Mr. Porcelain and Mr. Peterman were expensed in our Unallocated segment. We have also entered into employment and/or change of control agreements with certain of our executive officers and certain key employees. All of these agreements may require payments by us, in certain circumstances, including, but not limited to, a change in control of the Company or termination of the employee.

Goodwill [Abstract]
Goodwill	Long-lived Assets, including Goodwill The following table represents goodwill by reportable operating segment as of July 31, 2024 and July 31, 2023: Satellite and Space Communications Terrestrial and Wireless Networks Total Balance as of July 31, 2023 $ 173,602,000 174,090,000 $ 347,692,000 PST Divestiture (14,587,000) — (14,587,000) Goodwill impairment (48,925,000) — (48,925,000) Balance as of July 31, 2024 $ 110,090,000 174,090,000 $ 284,180,000 During the first quarter of fiscal 2024, we determined that the PST Disposal Group met the criteria to be classified as held for sale. Because the PST Disposal Group represented the disposal of a portion of the Satellite and Space Communications reporting unit, we assigned $14,587,000 of goodwill to the PST Disposal Group on a relative fair value basis. For purposes of allocating goodwill to the PST Disposal Group, we determined the fair value of the PST Disposal Group (based on consideration received from the sale transaction) and the fair value of the retained businesses of the Satellite and Space Communications reporting unit (based on a combination of the income and market approach). In conjunction with the relative fair value allocation, we tested goodwill assigned to the PST Disposal Group and retained businesses of the Satellite and Space Communications reporting unit for impairment and concluded that no impairment existed at the time the held for sale criteria were met. As discussed further in Note (3) - " Business Divestiture ," we completed the PST Divestiture in the second quarter of fiscal 2024 and reduced goodwill by $14,587,000 as part of determining the loss on business divestiture. In accordance with FASB ASC 350, we perform a goodwill impairment analysis at least annually (in the first quarter of each fiscal year), unless indicators of impairment exist in interim periods. If we fail the quantitative assessment of goodwill impairment ("quantitative assessment"), we would be required to recognize an impairment loss equal to the amount that a reporting unit's carrying value exceeded its fair value; however, any loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. During the fourth quarter of fiscal year 2024, our lower than expected financial performance, default on certain credit facility covenants and the sustained decrease in stock price since August 1, 2023 were considered triggering events which required a quantitative impairment test as of July 31, 2024. We performed a quantitative assessment using market participant assumptions to determine if the fair value of each of our reporting units with goodwill exceeded its carrying value. In making this assessment, we considered, among other things, expectations of projected net sales and cash flows, assumptions impacting the weighted average cost of capital, trends in trading multiples of comparable companies, changes in our stock price and changes in the carrying values of our reporting units with goodwill. We also considered overall business conditions. In performing the quantitative assessment, we estimated the fair value of each of our reporting units using a combination of the income and market approaches. The income approach, also known as the discounted cash flow ("DCF") method, utilizes the present value of cash flows to estimate fair value. The future cash flows for our reporting units were projected based on our estimates, at that time, of future revenues, operating income and other factors (such as working capital and capital expenditures). For purposes of conducting our impairment analysis, we assumed revenue growth rates and cash flow projections that are below our actual long-term expectations. The discount rates used in our DCF method were based on a weighted-average cost of capital ("WACC") determined from relevant market comparisons, adjusted upward for specific reporting unit risks (primarily the uncertainty of achieving projected operating cash flows). A terminal value growth rate was applied to the final year of the projected period, which reflects our estimate of stable, perpetual growth. We then calculated a present value of the respective cash flows for each reporting unit to arrive at an estimate of fair value under the income approach. Under the market approach, we estimated a fair value based on comparable companies' market multiples of revenues and earnings before interest, taxes, depreciation and amortization and factored in a control premium. Finally, we compared our estimates of fair values to our total public market capitalization and assessed implied control premiums based on our common stock price of $3.17 as of the date of testing. Ultimately, based on our quantitative evaluation, we determined that the carrying value of our Satellite and Space Communications reporting unit exceeded its fair value and recognized a goodwill impairment loss of $48,925,000 in fiscal 2024 in our Consolidated Statements of Operations. We also determined that our Terrestrial and Wireless Networks reporting unit had an estimated fair value in excess of its carrying value of at least 24.7% and concluded that our goodwill for this reporting unit was not impaired. In connection with our decision in July 2024 to exit our subsidiary operations in Basingstoke, United Kingdom, such operations became a separate asset group (the “U.K. Asset Group”) and we assessed the recoverability of the carrying value of the U.K. Asset Group under the accounting standards for assets held and used as of July 31, 2024. The undiscounted future cash flows to complete the exit of our Basingstoke operations indicated that the carrying amount of the asset group is not recoverable. The fair value of the U.K. Asset Group was estimated using an income approach and was lower than the U.K Asset Group’s carrying amount. As a result, we recorded a long-lived asset impairment charge of $15,600,000 within the Satellite and Space Communications segment in our fiscal 2024 Consolidated Statements of Operations. We allocated $9,925,000 of this impairment to the carrying value of Intangibles with Finite Lives, net, $2,651,000 to Property, Plant & Equipment, net, $1,873,000 to Other Assets, net and $1,151,000 to Operating Lease Right-of-Use Assets, net. In addition, as disclosed in Note (1) Summary of Significant Accounting and Reporting Policies, Liquidity and Going Concern , the Credit Facility was amended on October 17, 2024 to waive certain defaults or events of default, including in connection with our Net Leverage Ratio and a Fixed Charge Coverage Ratio covenants as of July 31, 2024. Although we have cured our defaults under the Credit Facility, a sustained significant decline in our actual operating performance, as compared to our forecast, and/or a continued sustained decline in our common stock price, may require us to perform another interim quantitative impairment test, which may result in an impairment of the goodwill assigned to both of our reporting units by an amount that could be material if we conclude our forecasted operating results will be adversely impacted for the foreseeable future. In any event, we are required to perform the next annual goodwill impairment analysis on August 1, 2025 (the start of our fiscal 2026). If our assumptions and related estimates change in the future, or if we change our reporting unit structure or other events and circumstances change (e.g., a sustained decrease in the price of our common stock (considered on both absolute terms and relative to peers)), we may be required to record impairment charges when we perform these tests, or in other future periods. Any impairment charges that we may record in the future could be material to our results of operations and financial condition.

Amortization expense for the fiscal years ended July 31, 2024, 2023 and 2022 was $21,154,000, $21,396,000 and $21,396,000, respectively. The estimated amortization expense consists of the following for the fiscal years ending July 31: 2025 $ 21,722,000 2026 19,128,000 2027 17,774,000 2028 17,774,000 2029 16,353,000 We review net intangible assets with finite lives for impairment when an event occurs indicating the potential for impairment. Based on our last assessment, we performed an impairment assessment of our Satellite and Space Communications segment’s long-lived assets in response to triggering events indicating potential impairment, namely the overall decline in financial performance of the segment and the Company’s decision to either complete a sale or wind-down our steerable antenna operations in the United Kingdom by the end of the first quarter of fiscal 2025. As such, we recognized an impairment loss of $9,925,000, related to net intangible assets with definite lives, which is included within intangible asset accumulated amortization Note (1)(h) - " Summary of Significant Accounting and Reporting Policies, Long-Lived Assets " for more information We believe that the carrying values of our remaining net intangible assets were recoverable as of July 31, 2024. However, if business conditions deteriorate, we may be required to record impairment losses, and/or increase the amortization of intangibles in the future. Any impairment charges that we may record in the future could be material to our results of operations and financial condition.

On December 13, 2023, we and the Investors agreed to change certain terms of the Series A Convertible Preferred Stock, effected through an Exchange Agreement (the “Exchange Agreement”), pursuant to which the Investors exchanged (the “Series A Exchange”) all 100,000 shares of Series A Convertible Preferred Stock outstanding for 100,000 shares of our newly issued Series A-1 Convertible Preferred Stock, par value $0.10 per share (the “Series A-1 Convertible Preferred Stock”), with an initial liquidation preference of $1,134.20 per share. As a result of the Series A Exchange, no shares of Series A Convertible Preferred Stock remain outstanding. On January 22, 2024, we entered into a Subscription and Exchange Agreement (the “Subscription and Exchange Agreement”) with the Investors, relating to: (i) the issuance and sale of 45,000 shares of Series B Convertible Preferred Stock, par value $0.10 per share (the “Series B Convertible Preferred Stock”), for an aggregate purchase price of $45,000,000, or $1,000 per share (the “Primary Issuance”), (ii) the exchange of 100,000 shares of our Series A-1 Convertible Preferred Stock for 115,721.22 shares of Series B Convertible Preferred Stock (the “Series B Exchange”) and (iii) the issuance to the Investors of 5,400 shares of Series B Convertible Preferred Stock in lieu of cash for certain expense reimbursements (the “Additional Issuance” and, together with the Primary Issuance and the Series B Exchange, the “Series B Issuance”). As a result of the Series B Exchange, no shares of Series A-1 Convertible Preferred Stock remain outstanding. We received $43,200,000 of cash proceeds from the Primary Issuance, net of $1,800,000 for certain expense reimbursements. On June 17, 2024, in connection with entering into the Credit Facility discussed in Note (8) - "Credit Facility," we and the Investors agreed to change certain terms of the Series B Convertible Preferred Stock. The changes altered the preferred holders’ existing consent rights and existing put rights alongside payments upon a change of control following specified asset sales, in each case consistent with the Credit Facility. To effect these changes, we and the Investors entered into a Subscription and Exchange Agreement (the “Series B-1 Exchange”), pursuant to which the Investors: (i) exchanged, in a transaction exempt from registration under the Securities Act of 1933, all of the 166,121.22 shares of Series B Convertible Preferred Stock outstanding for 166,121.22 shares of our newly issued Series B-1 Convertible Preferred Stock, par value $0.10 per share, with an initial liquidation preference of $1,036.58 per share, and (ii) received 5,705.83 additional shares of Series B-1 Convertible Preferred Stock. Also, on June 17, 2024, we and the Investors entered into a Voting Agreement and Registration Rights Agreement and filed a Series B-1 Certificate of Designations with the Secretary of State of Delaware, complete copies of which are documented and filed with the SEC. Except for the changes described above, the powers, preferences and rights of the Series B-1 Convertible Preferred Stock are substantially the same as those of the Series B Convertible Preferred Stock, including, without limitation, that the shares of Series B-1 Convertible Preferred Stock are convertible into shares of common stock at a conversion price of $7.99 per share (the same as the current conversion price of the Series B Convertible Preferred Stock, and subject to the same adjustments). We did not receive any cash proceeds from the Series B-1 Exchange. The Series B-1 Convertible Preferred Stock ranks senior to the shares of our common stock, with respect to the payment of dividends and the distribution of assets upon a liquidation, dissolution or winding up of the Company. The Series B-1 Convertible Preferred Stock has an initial liquidation preference of $1,036.58 per share with each share entitled to a cumulative dividend (the “Dividend”) at the rate of 9.00% per annum, compounding quarterly, paid-in-kind, or 7.75% per annum, compounding quarterly, paid in cash, at our election, or 6.50% per annum, in respect of any shares of Series B-1 Convertible Preferred Stock that remain outstanding following the redemption of at least fifty percent (50%) of the Series B-1 Preferred Stock pursuant to the exercise of an asset sale put right and/or an asset sale call right as described below. For any quarter in which we elect not to pay the Dividend in cash, such Dividend becomes part of the liquidation preference of the Series B-1 Convertible Preferred Stock. In addition, no dividend or other distribution on our common stock will be declared or paid on our common stock unless, at the time of such declaration and payment, an equivalent dividend or distribution is declared and paid on the Series B-1 Convertible Preferred Stock (the “Participating Dividend”), provided that in the case of any such dividend in the form of cash, in lieu of a cash payment, such Participating Dividend will become part of the liquidation preference of the Series B-1 Convertible Preferred Stock. Such Participating Dividend results in the Series B-1 Convertible Preferred Stock meeting the definition of a "participating security" for purposes of our earnings per share calculations. The shares of Series B-1 Convertible Preferred Stock are convertible into shares of common stock at the option of the holder thereof at any time. At any time after July 22, 2027, we have the right to mandate conversion of the Series B-1 Convertible Preferred Stock, subject to certain restrictions based on the price of our common stock in the preceding thirty (30) trading days. The conversion price for the Series B-1 Convertible Preferred Stock is $7.99, subject to certain adjustments set forth in the certificate of designations governing the Series B-1 Convertible Preferred Stock (the "Series B-1 Certificate of Designations"). Holders of the Series B-1 Convertible Preferred Stock are entitled to vote with the holders of our common stock on an as-converted basis, and are entitled to a separate class vote with respect to, among other things, amendments to our organizational documents that have an adverse effect on the Series B-1 Convertible Preferred Stock, authorizations or issuances of securities of the Company (other than the issuance of up $50,000,000 of shares of common stock), the payment of dividends, related party transactions, repurchases or redemptions of securities of the Company, dispositions of businesses or assets involving consideration having a fair value in excess of $75,000,000, the incurrence of certain indebtedness and certain amendments or extensions of our Credit Facility on terms and conditions that, taken as a whole, (A) are materially different from the existing Credit Facility or (B) adversely affect our ability to perform our obligations in connection with an optional repurchase of the Series B-1 Convertible Preferred Stock, in each case, subject to the exceptions and qualifications set forth in the Series B-1 Certificate of Designations. Holders have the right to require us to repurchase their Series B-1 Convertible Preferred Stock (at 1.0x the liquidation preference, plus accrued and unpaid dividends) on a date occurring either: (a) on or after October 31, 2028 or (b) upon the consummation of an asset sale meeting certain criteria. We have the right to repurchase all, or less than all, of the Series B-1 Convertible Preferred Stock upon the consummation of an asset sale meeting the same criteria, other than an asset sale that would result in a change of control. In addition, each holder will have the right to cause us to repurchase its Series B-1 Convertible Preferred Stock in connection with a Change of Ccontrol (as defined in the Series B-1 Certificate of Designations) at 1.5x (or 1.0x in the case of Series B-1 Convertible Preferred Stock issued in the Additional Issuance) the liquidation preference, plus accrued and unpaid dividends. Any repurchase described above would be subject to the terms set forth in the Series B-1 Certificate of Designations. Upon a repurchase of the Series B-1 Convertible Preferred Stock occurring as a result of an asset sale described above, we will issue each respective holder a warrant (a “Warrant”). A Warrant will represent the right to acquire our common stock, as further described in the Subscription and Exchange Agreement, for a term of five years and six months from the issuance of such Warrant, at an initial exercise price equal to the conversion price on the date of issuance of such Warrant, subject to certain adjustments. We determined that our obligation to issue a Warrant met the definition of a freestanding financial instrument that should be accounted for as a liability. We established an initial Warrant liability of $6,440,000, which was included in the consideration given to the Investors for purposes of determining the loss on extinguishment of the Series A-1 Convertible Preferred Stock as of January 31, 2024. The Warrant liability is classified in " Other Liabilities " on the Consolidated Balance Sheets and is remeasured to its estimated fair value each reporting period, using Level 3 fair value inputs, until the Warrant is exercised or expires. Changes in the estimated fair value of the Warrant will be recognized in our Consolidated Statement of Operations as a non-cash expense or benefit. As of July 31, 2024, the Warrant liability was remeasured, resulting in a $5,730,000 reduction to its estimated fair value. We accounted for the cancellation of our Series A-1 Convertible Preferred Stock and Series B Convertible Preferred Stock as extinguishments based on a qualitative assessment of the terms of the preferred shares exchanged. We recognized a $19,555,000 loss on extinguishment, representing the aggregate value of the Warrant and additional issuances related to certain expense reimbursements. As the Series A-1 Convertible Preferred Stock and Series B Convertible Preferred Stock were each classified as temporary equity, the loss on extinguishment was accounted for as a dividend to the holders and charged against retained earnings, and included in net loss attributable to common shareholders. In accordance with ASC 480, " Distinguishing Liabilities from Equity ," specifically ASC 480-10-S99-3A(2), SEC Staff Announcement: Classification and Measurement of Redeemable Securities , we classified the Series B-1 Convertible Preferred Stock outside of permanent equity as temporary equity since the redemption of such shares is not solely within our control and we could be required by the holder to redeem the shares for cash or other assets, at their option. Upon the Series B-1 Exchange, the initial redemption value (and estimated fair value) of the Series B-1 Convertible Preferred Stock was $178,112,000. We have elected to adjust the carrying value of the Series B-1 Convertible Preferred Stock to its current redemption value of $180,076,000, which includes $623,000 of cumulative dividends paid-in-kind and $1,341,000 of accumulated and unpaid dividends. During fiscal 2024, the adjustments charged against retained earnings to increase the carrying value of outstanding convertible preferred stock to their respective redemption values totaled $15,900,000, of which $12,390,000 related to the Series B and B-1 Convertible Preferred Stock and $3,510,000 related to the Series A and A-1 Convertible Preferred Stock (while outstanding). Subsequent Event On October 17, 2024, we and the Investors agreed to change certain terms of the Series B-1 Convertible Preferred Stock. The changes (i) altered the date on which preferred holders can opt to have us repurchase their Series B-2 Convertible Preferred Shares (as defined below) in certain circumstances, (ii) provided for increases to the dividend rate in certain circumstances and provided for an option for the preferred holders to elect to receive dividends in cash (to the extent permitted by law), and (iii) clarified the preferred holders’ existing consent rights, among other things. To effect the changes described above, we and the Investors entered into a Subscription and Exchange Agreement, pursuant to which the Investors (i) exchanged (the “Series B-2 Exchange”) all of the 171,827.05 shares of Series B-1 Convertible Preferred Stock outstanding for 171,827.05 shares of our newly issued Series B-2 Convertible Preferred Stock, par value $0.10 per share, with an initial liquidation preference of $1,067.87 per share (the per share liquidation preference of the Series B-1 Convertible Preferred Stock as of the date of issuance), and (ii) received 3,436.53 additional shares of Series B-2 Convertible Preferred Stock (collectively, the “Series B-2 Convertible Preferred Stock”). We did not receive any cash proceeds from the exchange and issuance of Series B-2 Convertible Preferred Stock. As a result of the Series B-2 Exchange, no shares of Series B-1 Convertible Preferred Stock remain outstanding as of October 17, 2024.

Restructuring and Related Activities [Abstract]
Cost Reduction	Cost Reduction Activities In fiscal 2023, we transformed and integrated our individual businesses into two segments to improve operational performance. This transformation has provided insight into opportunities to manage costs, streamline operations, improve efficiency, and accelerate decision-making by eliminating management layers and other redundancies. In doing so, during fiscal 2023, we recorded $3,872,000 of severance costs in selling, general and administrative expenses in our Consolidated Statements of Operations, of which $1,989,000, $1,220,000 and $663,000 related to our Satellite and Space Communications, Terrestrial and Wireless Networks and Unallocated segments, respectively. We paid $2,320,000 of severance costs during fiscal 2023 and our severance liability as of July 31, 2023 was $1,552,000. In fiscal 2024, we continued to transform and integrate our businesses, and in July 2024 made a decision to exit our subsidiary operations in Basingstoke U.K. and recorded total severance costs of $2,616,000 in selling, general and administrative expenses in our Consolidated Statements of Operations, of which a substantial portion was related to our Satellite and Space Communications segment. After net payments of $3,139,000 during fiscal 2024, our severance liability as of July 31, 2024 was $1,029,000.

Subsequent Events [Abstract]
Subsequent Events	Subsequent Event Subordinated Credit Agreement On October 17, 2024 (the "closing date"), we entered into a subordinated credit agreement with the existing holders of our convertible preferred stock and U.S. Bank Trust Company, National Association, as agent (the “Subordinated Credit Agreement”) which provides a subordinated unsecured term loan facility in the aggregate principal amount of $25,000,000 (the “Subordinated Credit Facility”). The proceeds of the Subordinated Credit Facility (i) cured our default on certain financial covenants under the Amended Credit Agreement with respect to the fourth quarter of fiscal 2024, (ii) provide us with additional liquidity and (iii) will fund our general working capital needs, including support of our transformation initiatives. The Subordinated Credit Facility is subject to a Make-Whole Amount with respect to certain repayments or prepayments. The Make-Whole Amount is an amount equal to (i) from the closing date through (but not including) the date that is nine months thereafter, $25,000,000 multiplied by 33.0%, (ii) from the date that is nine months after the closing date through (but not including) the date that is the second anniversary of the closing date, $25,000,000 multiplied by 50.0%, (iii) from the second anniversary of the closing date and thereafter, $25,000,000 multiplied by 75.0% plus, in the case of clause (iii), interest accrued on $25,000,000 at the Make-Whole Interest Rate (as defined below) starting on the second anniversary of the closing date and calculated as of any such date of determination. The Make-Whole Interest Rate is a rate equal to 16.0% per annum, which is increased by 2.0% per annum upon the occurrence and during the continuation of an event of default under the Subordinated Credit Facility. The obligations under the Subordinated Credit Facility are guaranteed by the same guarantors under the Amended Credit Facility and matures 90 days after the Maturity Date under the Amended Credit Facility as discussed in Note (8) – “Credit Facility.” The Subordinated Credit Facility contains customary representations, warranties and affirmative covenants, in each case substantially consistent with the representations and warranties and affirmative covenants under the Amended Credit Agreement. The Subordinated Credit Facility contains customary negative covenants, subject to negotiated exceptions, including but not limited to: (i) liens, (ii) investments, (iii) indebtedness, (iv) significant corporate changes, including mergers and acquisitions, (v) dispositions, (vi) restricted payments, including stockholder dividends, and (vii) certain other restrictive agreements. The outstanding Subordinated Credit Facility will not be considered debt for purposes of our financial covenant testing under the Credit Facility. Capitalized terms used but not defined herein have the meanings set forth for such terms in the Subordinated Credit Facility, which has been documented and filed with the SEC.

Summary of Significant Accounting and Reporting Policies (Policy)	12 Months Ended

Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation The accompanying consolidated financial statements include the accounts of Comtech Telecommunications Corp. and its subsidiaries ("Comtech," "we," "us," or "our"), all of which are wholly-owned. All significant intercompany balances and transactions have been eliminated in consolidation. Liquidity and Going Concern Pursuant to the requirements of ASC Topic 205-40, " Disclosure of Uncertainties About an Entity’s Ability to Continue as a Going Concern ," we are required to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about our ability to continue as a going concern. This evaluation does not take into consideration the potential mitigating effect of our plans that have not been fully implemented or are not within our control as of the date the audited Consolidated Financial Statements are issued. When substantial doubt exists, we are required to evaluate whether the mitigating effect of our plans sufficiently alleviates substantial doubt about our ability to continue as a going concern. The mitigating effect of our plans, however, is only considered if both (i) it is probable that the plans will be effectively implemented within one year after the date that the Consolidated Financial Statements are issued, and (ii) it is probable that the plans, when implemented, will mitigate the relevant conditions or events that raise substantial doubt about our ability to continue as a going concern within one year after the date that the Consolidated Financial Statements are issued. As of the date these financial statements were issued (the "issuance date"), we evaluated whether the following adverse conditions, when considered in the aggregate, raise substantial doubt about our ability to continue as a going concern over the next twelve months beyond the issuance date. Over the past three fiscal years, we incurred operating losses of $79,890,000, $14,660,000 and $33,752,000 in fiscal 2024, 2023 and 2022, respectively. In addition, over the past three fiscal years, net cash used in operating activities was $54,495,000 and $4,433,000 in fiscal 2024 and 2023, respectively, and net cash provided by operating activities was $1,997,000 in fiscal 2022. Our ability to meet future anticipated liquidity needs over the next year beyond the issuance date will largely depend on our ability to generate positive cash inflows from operations, maximize our borrowing capacity under our Credit Facility, as discussed further below, and or secure other sources of outside capital. While we believe we will be able to generate sufficient positive cash inflows, maximize our borrowing capacity and secure outside capital, there can be no assurance our plans will be successfully implemented and, as such, we may be unable to continue as a going concern over the next year beyond the issuance date. As discussed further in Note (8) – “Credit Facility,” on June 17, 2024, we entered into a $222,000,000 credit facility with a new syndicate of lenders, which replaced our prior credit facility. As further discussed below, we subsequently amended the credit facility on October 17, 2024 (the "Credit Facility"). The Credit Facility consists of a committed $162,000,000 term loan (“Term Loan”) and $60,000,000 revolving loan (“Revolver Loan”). At July 31, 2024 and October 25, 2024 (the date closest to the issuance date), total outstanding borrowings under the Credit Facility were $194,163,000 and $199,067,000, respectively. At both July 31, 2024 and October 25, 2024, $32,500,000 was drawn on the Revolver Loan. As of the issuance date, our available sources of liquidity approximate $28,700,000, consisting solely of qualified cash and cash equivalents. That is, our available sources of liquidity do not include the remaining portion of the committed Revolver Loan due to the lenders' consent right, discussed below, to any borrowings that exceed $32,500,000. The Credit Facility, among other things, requires compliance with new restrictive and financial covenants, including: a maximum allowable Net Leverage Ratio of 3.25x for the fiscal quarter ending January 31, 2025; a minimum Fixed Charge Coverage Ratio of 1.20x for the fiscal quarter ending January 31, 2025; a minimum Average Liquidity requirement at each quarter end of $20,000,000; and a minimum EBITDA of $35,000,000 for the fiscal quarter ending October 31, 2025. Such ratios adjust under the Credit Facility in future periods. The Credit Facility was amended on October 17, 2024 to waive certain defaults or events of default, including in connection with our Net Leverage Ratio and Fixed Charge Coverage Ratio covenants as of July 31, 2024. The amendment also provides for, among other things: (i) increases the interest rate margins applicable to the loans; (ii) modifies certain financial and collateral reporting requirements; (iii) provides a lender consent right with respect to $27,500,000 of Revolver Loan borrowings above $32,500,000; (iv) permits the incurrence of $25,000,000 of senior unsecured subordinated debt (as described below); (v) amends the maturity date to the earlier of (x) July 31, 2028 or (y) 90 days prior to the earliest date that the debt under the Subordinated Credit Agreement (as defined below) becomes due and payable; and (vi) suspends financial covenant testing through the end of our fiscal quarter ending January 31, 2025. In addition, we entered into a Subordinated Credit Agreement with the existing holders of our Convertible Preferred Stock (the “Subordinated Credit Agreement”) on October 17, 2024, which provides a subordinated unsecured term loan facility in the aggregate principal amount of $25,000,000 (the “Subordinated Credit Facility”). The proceeds of the Subordinated Credit Facility: (i) cured our default on certain financial covenants under the Credit Facility, as discussed above; (ii) provides additional liquidity to us; and (iii) funds our general working capital needs, including support of our strategic transformation initiatives, as discussed below. Our ability to meet our current obligations as they become due may be impacted by our ability to remain compliant with the financial covenants required by the Credit Facility, or to obtain future waivers or amendments from the lenders in the event compliance is not maintained. While we believe we will be able to secure such waivers or amendments, as needed, there can be no assurance such waivers or amendments will be secured or on terms that are acceptable to us. If we are unable to secure waivers or amendments, the lenders may declare an event of default, which would cause an immediate acceleration and repayment of all outstanding principal, interest and fees due under our Credit Facility. Absent our ability to repay the forgoing amounts upon the declaration of an event of default, the lenders may exercise their rights and remedies under the Credit Facility, which may include, among others, a seizure of substantially all of our assets and/or the liquidation of our operations. If an event of default occurs that allows the lenders to exercise these rights and remedies over the next year beyond the issuance date, we will be unable to continue as a going concern. As of the issuance date, our plans to address our ability to continue as a going concern include, among other things: • executing a strategy to transform Comtech into a pure-play satellite and space communications company (ongoing and future actions supporting our transformation strategy include: an exploration of strategic alternatives for our Terrestrial and Wireless Networks segment, which is well underway; the pursuit of further portfolio-shaping opportunities to enhance profitability, efficiency and focus; and the implementation of additional operational initiatives to both achieve profitable results from operations as well as to align our go-forward cost structure with a pure-play focus on satellite and space communications), as discussed further in Note (18) – “Cost Reduction Activities;” • pursuing initiatives to reduce investments in working capital, namely accounts receivable and inventory; • improving process disciplines to attain and maintain profitable operations by entering into more favorable sales or service contracts; • reevaluating our business plans to identify opportunities (e.g., within our Satellite and Space Communications segment) to focus future investment on our most strategic, high-margin revenue opportunities; • reevaluating our business plans to identify opportunities to further reduce capital expenditures; • seeking opportunities to improve liquidity through any combination of debt and/or equity financing (including possibly restructuring our Credit Facility, Convertible Preferred Stock and/or Subordinated Credit Agreement); and • seeking other strategic transactions and/or measures including, but not limited to, the potential sale or divestiture of assets.
Nature of Business	Nature of Business We design, produce and market innovative products, systems and services for advanced communications solutions. We conduct our business through two reportable operating segments: Satellite and Space Communications and Terrestrial and Wireless Networks. Our business is highly competitive and characterized by rapid technological change. Our growth and financial position depends on our ability to keep pace with such changes and developments and to respond to the sophisticated requirements of an increasing variety of secure wireless communications technology users, among other things. Many of our competitors are substantially larger, and have significantly greater financial, marketing and operating resources and broader product lines than our own. A significant technological or sales breakthrough by others, including smaller competitors or new companies, could have a material adverse effect on our business. In addition, certain of our customers have technological capabilities in our product areas and could choose to replace our products with their own. International sales expose us to certain risks, including barriers to trade, fluctuations in foreign currency exchange rates (which may make our products less price competitive), political and economic instability, availability of suitable export financing, export license requirements, tariff regulations, and other United States ("U.S.") and foreign regulations that may apply to the export of our products, as well as the generally greater difficulties of doing business abroad. We attempt to reduce the risk of doing business in foreign countries by seeking contracts denominated in U.S. dollars, advance or milestone payments, credit insurance and irrevocable letters of credit in our favor.
Revenue Recognition	Revenue Recognition In accordance with FASB ASC 606 - Revenue from Contracts with Customers ("ASC 606"), we record revenue in an amount that reflects the consideration to which we expect to be entitled in exchange for goods or services promised to customers. Under ASC 606, we follow a five-step model to: (1) identify the contract with our customer; (2) identify our performance obligations in our contract; (3) determine the transaction price for our contract; (4) allocate the transaction price to our performance obligations; and (5) recognize revenue using one of the following two methods: • Over time - We recognize revenue using the over time method when there is a continuous transfer of control to the customer over the contractual period of performance. This generally occurs when we enter into a long-term contract relating to the design, development or manufacture of complex equipment or technology platforms to a buyer’s specification (or to provide services related to the performance of such contracts) for which we have determined there is no alternative use, as defined in ASC 606. Continuous transfer of control is typically supported by contract clauses which allow our customers to unilaterally terminate a contract for convenience, pay for costs incurred plus a reasonable profit and take control of work-in-process. Revenue recognized over time is generally based on the extent of progress toward completion of the related performance obligations. The selection of the method to measure progress requires judgment and is based on the nature of the products or services provided. In certain instances, typically for firm fixed-price contracts, we use the cost-to-cost measure because it best depicts the transfer of control to the customer which occurs as we incur costs on our contracts. Under the cost-to-cost measure, the extent of progress toward completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion, including warranty costs. Revenues, including estimated fees or profits, are recorded proportionally as costs are incurred. Costs to fulfill generally include direct labor, materials, subcontractor costs, other direct costs and an allocation of indirect costs. When these contracts are modified, the additional goods or services are generally not distinct from those already provided. As a result, these modifications form part of an existing contract and we must update the transaction price and our measure of progress for the single performance obligation and recognize a cumulative catch-up to revenue and gross profits. For over time contracts using a cost-to-cost measure of progress, we have an estimate at completion ("EAC") process in which management reviews the progress and execution of our performance obligations. This EAC process requires management judgment relative to assessing risks, estimating contract revenue and costs, and making assumptions for schedule and technical issues. Since certain contracts extend over a long period of time, the impact of revisions in revenue and/or cost estimates during the progress of work may impact current period earnings through a cumulative adjustment. Additionally, if the EAC process indicates a loss, a provision is made for the total anticipated loss in the period that it becomes evident. Contract revenue and cost estimates for significant contracts are generally reviewed and reassessed at least quarterly. The cost-to-cost method is principally used to account for contracts in our Satellite and Space Communications segment and, to a lesser extent, certain location-based and messaging infrastructure contracts in our public safety and location technologies product line within our Terrestrial and Wireless Networks segment. For service-based contracts in our Terrestrial and Wireless Networks segment, we also recognize revenue over time. These services are typically recognized as a series of services performed over the contract term using the straight-line method, or based on our customers’ actual usage of the networks and platforms which we provide. • Point in time - When a performance obligation is not satisfied over time, we must record revenue using the point in time accounting method which generally results in revenue being recognized upon shipment or delivery of a promised good or service to a customer. This generally occurs when we enter into short term contracts or purchase orders where items are provided to customers with relatively quick turn-around times. Modifications to such contracts and/or purchase orders, which typically provide for additional quantities or services, are accounted for as a new contract because the pricing for these additional quantities or services are based on standalone selling prices. Point in time accounting is principally applied to contracts in our satellite ground station technologies product line (which includes satellite modem and traveling wave tube amplifiers). The contracts related to these product lines do not meet the requirements for over time revenue recognition because our customers cannot utilize the equipment for its intended purpose during any phase of our manufacturing process; customers do not simultaneously receive and/or consume the benefits provided by our performance; customers do not control the asset (i.e., prior to delivery, customers cannot direct the use of the asset, sell or exchange the equipment, etc.); and, although many of our contracts have termination for convenience clauses and/or an enforceable right to payment for performance completed to date, our performance creates an asset with an alternative use through the point of delivery. In determining that our equipment has alternative use, we considered the underlying manufacturing process for our products. In the early phases of manufacturing, raw materials and work in process (including subassemblies) consist of common parts that are highly fungible among many different types of products and customer applications. Finished products are either configured to our standard configuration or based on our customers’ specifications. Finished products, whether built to our standard specification or to a customers’ specification, can be sold to a variety of customers and across many different end use applications with minimal rework, if needed, and without incurring a significant economic loss. When identifying a contract with our customer, we consider when it has approval and commitment from both parties, if the rights of the parties are identified, if the payment terms are identified, if it has commercial substance and if collectability is probable. When identifying performance obligations, we consider whether there are multiple promises and how to account for them. In our contracts, multiple promises are separated if they are distinct, both individually and in the context of the contract. If multiple promises in a contract are highly interrelated or comprise a series of distinct services performed over time, they are combined into a single performance obligation. In some cases, we may also provide the customer with an additional service-type warranty, which we recognize as a separate performance obligation. Service-type warranties do not represent a significant portion of our consolidated net sales. When service-type warranties represent a separate performance obligation, the revenue is deferred and recognized ratably over the extended warranty period. Our contracts, from time-to-time, may also include options for additional goods and services. To date, these options have not represented material rights to the customer as the pricing for them reflects standalone selling prices. As a result, we do not consider options we offer to be performance obligations for which we must allocate a portion of the transaction price. In many cases, we provide assurance-type warranty coverage for some of our products for a period of at least one year from the date of delivery. When identifying the transaction price, we typically utilize the contract's stated price as a starting point. The transaction price in certain arrangements may include estimated amounts of variable consideration, including award fees, incentive fees or other provisions that can either increase or decrease the transaction price. We estimate variable consideration as the amount to which we expect to be entitled, and we include estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the estimation uncertainty is resolved. The estimation of this variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of our anticipated performance and all information (e.g., historical, current and forecasted) that is reasonably available to us. When allocating the contract’s transaction price, we consider each distinct performance obligation. For contracts with multiple performance obligations, we allocate the contract’s transaction price to each performance obligation using our best estimate of the standalone selling price of each distinct good or service in the contract. We determine standalone selling price based on the price at which the performance obligation is sold separately. If the standalone selling price is not observable through past transactions, we estimate the standalone selling price taking into account available information such as market conditions, including geographic or regional specific factors, competitive positioning, internal costs, profit objectives and internally approved pricing guidelines related to the performance obligations. The timing of revenue recognition, billings and collections results in receivables, unbilled receivables and contract liabilities on our Consolidated Balance Sheets. Under typical payment terms for our contracts accounted for over time, amounts are billed as work progresses in accordance with agreed-upon contractual terms, either at periodic intervals (e.g., monthly) or upon achievement of contractual milestones. For certain contracts with provisions that are intended to protect customers in the event we do not satisfy our performance obligations, billings occur subsequent to revenue recognition, resulting in unbilled receivables. Under ASC 606, unbilled receivables constitute contract assets. There were no material impairment losses recognized on contract assets during the fiscal years ended July 31, 2024, 2023 and 2022. On large long-term contracts, and for contracts with international customers that do not do business with us regularly, payment terms typically require advanced payments and deposits. Under ASC 606, payments received from customers in excess of revenue recognized to-date results in a contract liability. These contract liabilities are not considered to represent a significant financing component of the contract because we believe these cash advances and deposits are generally used to meet working capital demands which can be higher in the earlier stages of a contract. Also, advanced payments and deposits provide us with some measure of assurance that the customer will perform on its obligations under the contract. Under the typical payment terms for our contracts accounted for at a point in time, costs are accumulated in inventory until the time of billing, which generally coincides with revenue recognition. Of the current contract liability balance of $66,351,000 at July 31, 2023 and $64,601,000 at July 31, 2022, $48,902,000 and $53,079,000 was recognized as revenue during fiscal years 2024 and 2023, respectively. We recognize the incremental costs to obtain or fulfill a contract as an expense when incurred if the amortization period of the asset is one year or less; otherwise, such costs are capitalized and amortized over the estimated life of the contract. During fiscal year 2024, incremental costs to obtain or fulfill contracts with an amortization period greater than one year were $2,863,000. During fiscal year 2023, incremental costs to obtain or fulfill contracts with an amortization period greater than one year were not material. Commissions payable to our internal sales and marketing employees or contractors that are incremental to the acquisition of long-term customer contracts are capitalized and amortized consistent with the pattern of revenue recognition through cost of sales on our Consolidated Statements of Operations. Commissions payable that are not incremental to the acquisition of long-term contracts are expensed as incurred in selling, general and administrative expenses on our Consolidated Statements of Operations. As for commissions payable to our third-party sales representatives related to large long-term contracts, we consider these types of commissions both direct and incremental costs to obtain and fulfill such contracts. Therefore, such commissions are included in total estimated costs at completion for such contracts and expensed over time through cost of sales on our Consolidated Statements of Operations.
Cash and Cash Equivalents	Cash and Cash Equivalents Our cash equivalents are short-term, highly liquid investments that are both readily convertible to known amounts of cash and have insignificant risk of change in value as a result of changes in interest rates. Our cash and cash equivalents, as of July 31, 2024 and 2023, amounted to $32,433,000 and $18,961,000, respectively, and primarily consist of bank deposits and money market deposit accounts insured by the Federal Deposit Insurance Corporation. Cash equivalents are carried at cost, which approximates fair value.
Inventories	Inventories Our inventories are stated at the lower of cost and net realizable value, the latter of which is defined as the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. Our inventories are reduced to their estimated net realizable value by a charge to cost of sales in the period such excess costs are determined. Our inventories are principally recorded using either average or standard costing methods. Work-in-process (including our contracts-in-progress) and finished goods inventory reflect all accumulated production costs, which are comprised of direct production costs and overhead, and is reduced by amounts recorded in cost of sales as the related revenue is recognized. Indirect costs relating to long-term contracts, which include expenses such as general and administrative, are charged to expense as incurred and are not included in our cost of sales or work-in-process (including our contracts-in-progress) and finished goods inventory.
Long-Lived Assets	Long-Lived Assets Our machinery and equipment, which are recorded at cost, are depreciated or amortized over their estimated useful lives (three to eight years) under the straight-line method. Capitalized internal use software costs are amortized once the software is placed in service under the straight-line method over the estimated useful life of the software, which is generally three years. Capitalized values of properties and leasehold improvements under leases are amortized over the life of the lease or the estimated life of the asset, whichever is less. Goodwill represents the excess cost of a business acquisition over the fair value of the net assets acquired. In accordance with FASB ASC 350 "Intangibles - Goodwill and Other" goodwill is not amortized. We periodically, at least on an annual basis in the first quarter of each fiscal year, review goodwill, considering factors such as projected cash flows and revenue and earnings multiples, to determine whether the carrying value of the goodwill is impaired. If we fail the quantitative assessment of goodwill impairment ("quantitative assessment"), we would be required to recognize an impairment loss equal to the amount that a reporting unit's carrying value exceeded its fair value; however, any loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. We define our reporting units to be the same as our operating segments. We perform our annual goodwill impairment test as of the first day of the fiscal year (August 1). Due to triggering events that occurred in the fourth quarter of fiscal year 2024, we performed a quantitative impairment test for each of our reporting units as of July 31, 2024. See Note (14) - "Long-lived Assets, including Goodwill" for additional information. The quantitative impairment test as of July 31, 2024 satisfies the Company’s annual goodwill impairment testing requirement as of August 1, 2024 due to the proximity of the testing dates. We assess the recoverability of the carrying value of our other long-lived assets, including identifiable intangible assets with finite useful lives, whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. We evaluate the recoverability of such assets based upon the expectations of undiscounted cash flows from such assets. If the sum of the expected future undiscounted cash flows were less than the carrying amount of the asset, a loss would be recognized for the difference between the fair value and the carrying amount. Due to a triggering event relating to our subsidiary operations in Basingstoke, United Kingdom, we assessed the recoverability of the carrying value of our other long-lived assets related to these operations. See Note (14) - "Long-lived Assets, including Goodwill"
Income Taxes	Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using the enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. We measure and account for uncertain tax positions taken or expected to be taken in income tax returns in accordance with the provisions of FASB ASC 740-10-25 " Income Taxes, " which prescribes a two-step evaluation process for tax positions. The first step is recognition based on a determination of whether it is more-likely-than-not that a tax position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. The second step is to measure a tax position that meets the more-likely-than-not threshold. The tax position is measured as the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement. If a tax position does not meet the more-likely-than-not recognition threshold, the benefit of that position is not recognized in the financial statements. Our policy is to recognize potential interest and penalties related to uncertain tax positions in income tax expense.
Earnings Per Share	Earnings Per Share Our basic earnings per share ("EPS") is computed based on the weighted average number of common shares (including vested but unissued stock units, share units, performance shares and restricted stock units ("RSUs")) outstanding during each respective period. Our diluted EPS reflects the dilution from potential common stock issuable pursuant to the exercise of equity-classified stock-based awards, warrants issued to our lenders in connection with entering the Credit Facility, settlement of escrow arrangements related to our acquisition of UHP Networks Inc. ("UHP") and the assumed conversion of Convertible Preferred Stock, if dilutive, outstanding during each respective period. The warrants contingently issuable to our preferred shareholders upon a repurchase of the Series B-1 Convertible Preferred Stock are not reflected in diluted EPS. Pursuant to FASB ASC 260 " Earnings Per Share, " shares whose issuance is contingent upon the satisfaction of certain conditions are included in diluted EPS based on the number of shares, if any, that would be issuable if the end of the reporting period were the end of the contingency period. When calculating our diluted earnings per share, we consider the amount an employee must pay upon assumed exercise of stock-based awards and the amount of stock-based compensation cost attributed to future services and not yet recognized. There were no repurchases of our common stock during the fiscal years ended July 31, 2024, 2023 and 2022. See Note (17) - " Stockholders’ Equity " for more information. Weighted average stock options, RSUs and restricted stock outstanding of 1,050,000, 972,000 and 1,656,000 shares for fiscal 2024, 2023 and 2022, respectively, were not included in our diluted EPS calculation because their effect would have been anti-dilutive. Our EPS calculations exclude 534,000, 385,000 and 293,000 weighted average performance shares outstanding for fiscal 2024, 2023 and 2022, respectively, as the performance conditions have not yet been satisfied. However, the numerator for EPS calculations for each respective period is reduced by the compensation expense related to these awards. Weighted average common shares of 174,000 related to warrants issued in connection with entering the Credit Facility on June 17, 2024 were not included in our diluted EPS calculation for fiscal 2024 because their effect would have been anti-dilutive. Weighted average common shares of 98,000, 260,000 and 591,000 related to our acquisition of UHP in March 2021 were not included in our diluted EPS calculation for fiscal 2024, 2023 and 2022, respectively, because their effect would have been anti-dilutive. As of July 31, 2024, all of the shares held in escrow related to the UHP acquisition were settled. Weighted average common shares of 13,581,000, 4,570,000 and 3,342,000 underlying the assumed conversion of Convertible Preferred Stock, on an if-converted basis, were not included in our diluted EPS calculation for fiscal 2024, 2023 and 2022, respectively, because their effect would have been anti-dilutive. As a result, the numerator for our basic and diluted EPS calculation for fiscal 2024, 2023 and 2022 is the respective net loss attributable to common stockholders.
Fair Value Measurements and Financial Instruments	Fair Value Measurements and Financial Instruments Using the fair value hierarchy described in FASB ASC 820 " Fair Value Measurements and Disclosures," we valued our cash and cash equivalents using Level 1 inputs that were based on quoted market prices. We believe that the carrying amounts of our other current financial assets (such as accounts receivable) and other current liabilities (including accounts payable, accrued expenses and the current portion of long-term debt) approximate their fair values due to their short-term maturities. The fair value of the non-current portion of our long-term debt approximates its carrying amount due to its variable interest rate and pricing grid that is dependent upon our leverage ratio as of such date. Level 3 inputs are unobservable inputs developed using the best available information under the circumstances. Level 3 inputs are supported by little or no market activity, are significant to the fair value of the assets or liabilities and reflect our assumptions related to how market participants would use similar inputs to price the asset or liability. As further discussed in Note (8) - " Credit Facility," we used Level 3 inputs to value the warrants issued to lenders in connection with our Credit Facility. As of July 31, 2024, we determined the fair value of such warrants based on the Black-Scholes option pricing model using the following estimates: exercise price of $0.10, risk free rate of 4.0%, volatility of 55.0%, and expected life of seven years. We also used Level 3 inputs to value the embedded derivative liability associated with our Credit Facility. As of July 31, 2024, we determined the fair value of the embedded derivative liability using a with-and-without scenario-based discounted cash flow method, which reflected our estimates regarding the probability and timing of events that could result in additional payments of interest and/or fees to such lenders as stated in our Credit Facility. As further discussed in Note (16) - " Convertible Preferred Stock," we used Level 3 inputs to value warrants contingently issuable under the terms of our Convertible Preferred Stock. As of July 31, 2024, we determined the fair value of Convertible Preferred Stock warrants using the Monte Carlo simulation model with the following assumptions: expected life of five months; risk free rate of 3.9%; expected volatility of 60.0%; and dividend yield of 0%. As of July 31, 2024 and 2023, other than the financial instruments discussed above, we had no other significant assets or liabilities included in our Consolidated Balance Sheets recorded at fair value, as such term is defined by FASB ASC 820.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amount of assets and liabilities, and disclosure of contingent assets and liabilities, at the date of the consolidated financial statements and the reported amounts of net sales and expenses during the reported period. We make significant estimates in many areas of our accounting, including but not limited to the following: liquidity and going concern assessments, revenue recognition related to contracts accounted for over time, stock-based compensation, intangible assets (including goodwill) and liabilities, provision for excess and obsolete inventory, allowance for doubtful accounts, warranty obligations and income taxes. Actual results may differ from those estimates.
Comprehensive Income	Comprehensive Income In accordance with FASB ASC 220 " Comprehensive Income ," we report all changes in equity during a period, except those resulting from investment by owners and distribution to owners, for the period in which they are recognized. Comprehensive income is the total of net income and all other non-owner changes in equity (or other comprehensive income) such as unrealized gains/losses on securities classified as available-for-sale, foreign currency translation adjustments and minimum pension liability adjustments. Comprehensive income (loss) was the same as our net income (loss) in fiscal 2024, 2023 and 2022.
Reclassifications	Reclassifications Certain reclassifications have been made to previously reported consolidated financial statements to conform to the fiscal 2024 presentation.
Adoption of Accounting Standards and Updates	Adoption of Accounting Standards and Updates We are required to prepare our consolidated financial statements in accordance with the Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") which is the source for all authoritative U.S. generally accepted accounting principles, which are commonly referred to as "GAAP." The FASB ASC is subject to updates by the FASB, which are known as Accounting Standards Updates ("ASUs"). During fiscal 2024 the following FASB ASUs have been issued and incorporated into the FASB ASC and have not yet been adopted by us as of July 31, 2024: • FASB ASU No. 2023-07, which requires the disclosure of significant segment expenses, by reportable segment, regularly provided to the chief operating decision maker (“CODM”) and included within each reported measure of segment profit or loss. The disclosure of other segment items by reportable segment are also required and would constitute the difference between segment revenues less these significant segment expenses and reported segment profit or loss. On an annual basis, the update requires an entity to disclose the CODM's title and position, as well as describe how the CODM uses the reported measures. Additionally, all existing annual disclosures about segment profit or loss must be provided on an interim basis in addition to the disclosure of significant segment expenses and other segment items. This ASU is effective for fiscal years beginning after December 15, 2023 (our fiscal year beginning on August 1, 2024) and for interim periods within fiscal years beginning after December 15, 2024 (our interim period beginning on August 1, 2025), with early adoption permitted. The adoption of this guidance will impact our disclosures only and we do not expect it to have a material impact on our consolidated financial statements. • FASB ASU No. 2023-09 enhances and establishes new income tax disclosure requirements in addition to modifying and eliminating certain existing requirements. Most notably under the new requirements is greater disaggregation of information in the effective tax rate reconciliation, including the inclusion of both percentages and amounts, specific categories, and additional information for reconciling items meeting a quantitative threshold defined by the guidance. Additionally, disclosures of income taxes paid and income tax expense must be disaggregated by federal, state and foreign taxes, with income taxes paid further disaggregated for individual jurisdictions that represent 5 percent or more of total income taxes paid. This ASU is effective for fiscal years beginning after December 15, 2024 (our fiscal year beginning on August 1,
