The preparation of our condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires us 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 condensed consolidated financial statements, and the reported amounts of net sales and expenses during the reported period. Actual results may differ from those estimates. Our condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements, filed with the Securities and Exchange Commission ("SEC"), for the fiscal year ended July 31, 2021 and the notes thereto contained in our Annual Report on Form 10-K, and all of our other filings with the SEC. Impact of Coronavirus Disease 2019 Pandemic ("COVID-19") and Global Supply Chain Constraints on Our Business Since March 2020, we conducted most of our non-production related operations using remote working arrangements, curtailed most business travel, and established social distancing safeguards. Both COVID-19 and the related global supply chain constraints have impacted our business, operating results and financial condition, as well as the operations and financial performance of many of the customers and suppliers in industries that we serve. We have experienced order and production delays, disruptions in component availability and pricing, lower levels of factory utilization and higher logistics and operational costs. Although such business conditions are expected to persist for most of our fiscal 2022, and may carry into fiscal 2023, we believe that our long-term fundamentals remain strong and that our business is well-positioned for growth once the aftershocks of the pandemic subside.

Business Combinations [Abstract]
Acquisitions	Acquisitions UHP Networks Inc. On March 2, 2021, we completed our acquisition of UHP Networks Inc. ("UHP"), a leading provider of innovative and disruptive satellite ground station technology solutions, pursuant to a stock purchase agreement initially entered into in November 2019 and amended in June 2020 and on March 1, 2021, respectively. With end-markets for high-speed satellite-based networks anticipated to significantly grow, our acquisition allows us to enhance our Commercial Solutions segment's offerings with low cost time division multiple access ("TDMA") satellite modems. The acquisition has a preliminary purchase price for accounting purposes of $37,470,000. Pursuant to the stock purchase agreement, during fiscal 2021, the initial upfront payment of approximately $23,979,000 was paid mostly in shares of our common stock, with $87,000 in cash. In August 2021, $3,991,000 of the $4,991,000 hold back amount previously placed into escrow at closing was paid to the seller in shares of our common stock, as the conditions pursuant to the stock purchase agreement were met. The stock purchase agreement also provides for a contingent earn-out payment of up to $9,000,000, also payable at our option in cash and or shares of our common stock, if specified sales milestones are reached during a defined period ending September 30, 2022. The preliminary estimated fair value of such contingent earn-out consideration at the acquisition date was $8,500,000. Of the $23,979,000 paid at closing, $4,560,000 was placed into escrow to be released ratably over three years upon settlement of potential indemnification obligations of the seller. We issued 1,026,567 shares of our common stock at closing, based on a volume weighted average stock price of approximately $28.14 per share, in satisfaction of initial payment and escrow arrangements under the terms of the stock purchase agreement. The terms of the stock purchase agreement provide an ability for us to substitute cash in lieu of the common stock that was initially placed into escrow. We are accounting for the acquisition under the acquisition method of accounting in accordance with FASB ASC 805, "Business Combinations" ("ASC 805"). The purchase price was allocated to the assets acquired and liabilities assumed, based on their preliminary fair value as of March 2, 2021 pursuant to the business combination accounting rules. Acquisition plan expenses were not included as a component of consideration transferred and were expensed in the period incurred. Our condensed consolidated statements of operations for the three and six months ended January 31, 2022 include a nominal amount of revenue contribution from the acquisition. Pro forma financial information is not disclosed, as the acquisition is not material. The following table summarizes the preliminary fair value of the assets acquired and liabilities assumed in connection with the acquisition: Purchase Price Allocation (1) Initial upfront payment $ 23,979,000 Hold-back amount 4,991,000 Contingent earn-out consideration 8,500,000 Preliminary purchase price at fair value $ 37,470,000 Preliminary allocation of aggregate purchase price: Cash and cash equivalents $ 1,391,000 Current assets 1,367,000 Property, plant and equipment 10,000 Deferred tax assets 310,000 Contract liabilities (648,000) Accrued warranty obligations (750,000) Other current liabilities (1,175,000) Non-current liabilities (160,000) Net tangible assets at preliminary fair value $ 345,000 Identifiable intangibles, deferred taxes and goodwill: Estimated Useful Lives Technology $ 15,300,000 15 years Customer relationships 15,500,000 15 years Trade name 800,000 20 years Deferred tax liabilities (8,374,000) Goodwill 13,899,000 Indefinite Preliminary allocation of aggregate purchase price $ 37,470,000 (1) As reported in the Company's Quarterly Report on Form 10-Q for the three months ended October 31, 2021. The acquired identifiable intangible assets are being amortized on a straight-line basis, which we believe approximates the pattern in which the assets are utilized over their estimated useful lives. The preliminary fair value of customer relationships was estimated primarily based on the value of the discounted cash flows that the related intangible asset could be expected to generate in the future. The preliminary fair value of technology and trade name was estimated based on the discounted capitalization of royalty expense saved because we now own the assets. The preliminary estimated fair value of contingent earn-out consideration represents the present value of the estimated amount payable, based on a probability-weighted amount of net sales, as defined, during the earn-out period, which reflects significant management estimates and assumptions using unobservable Level 3 inputs, including: (i) possible outcomes for targeted net sales during the earn-out period; (ii) timing of each possible outcome; (iii) probability of each possible outcome; and (vi) discount rate reflecting the credit risk of the Company. Among the factors contributing to the recognition of goodwill, as a component of the purchase price allocation, were synergies in products and technologies and the addition of a skilled, assembled workforce. This goodwill has been assigned to our Commercial Solutions segment based on specific identification and is generally not deductible for income tax purposes. The allocation of the preliminary purchase price shown in the above table was based upon a preliminary valuation and estimates and assumptions that are subject to change within the purchase price allocation period, generally one year from the acquisition date. The primary areas of the purchase price allocation not yet finalized include the purchase price (due to customary adjustments for potential indemnification obligations of the seller under the stock purchase agreement), a final assessment of assets acquired and liabilities assumed, accrued warranty obligations, income taxes and residual goodwill. Acquisition Plan Expenses During the three and six months ended January 31, 2021, we incurred acquisition plan expenses of $3,357,000 and $94,540,000, respectively. Of the amount recorded for the six months ended January 31, 2021, $88,343,000 related to the previously announced litigation and merger termination with Gilat Satellite Networks, Ltd. ("Gilat"), including $70,000,000 paid in cash to Gilat. The remaining costs primarily related to the April 2021 settlement of litigation associated with the 2019 acquisition of GD NG-911 as well as our acquisition of UHP, which closed in March 2021. Additionally, during the six months ended January 31, 2021, we recorded $1,178,000 of incremental interest expense related to a now terminated financing commitment letter.

Adoption of Accounting Standard

Accounting Standards Update and Change in Accounting Principle [Abstract]
Adoption of Accounting Standards and Updates	Adoption of Accounting Standards and Updates We are required to prepare our condensed 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 the six months ended January 31, 2022, we adopted: • FASB ASU No. 2019-12, which simplifies various aspects related to accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application. Our adoption of this ASU on August 1, 2021 did not have a material impact on our condensed consolidated financial statements or disclosures. • FASB ASU No. 2020-01, which clarifies the interactions between Topics 321, 323 and 815. This ASU clarifies that an entity should consider observable transactions that require it to either apply or discontinue the equity method of accounting for the purposes of applying the measurement alternative in accordance with Topic 321 immediately before applying or upon discontinuing the equity method. In addition, the amendments clarify the accounting for certain forward contracts and purchased options accounted for under Topic 815. Our adoption of this ASU on August 1, 2021 did not impact our condensed consolidated financial statements or disclosures. • FASB ASU No. 2020-06, which simplifies the accounting for convertible instruments by removing certain separation models (including the cash conversion model and the beneficial conversion feature model) for convertible instruments. As a result, for convertible instruments with conversion features that are not required to be accounted for as derivatives under Topic 815 or that do not result in substantial premiums accounted for as paid-in capital, the embedded conversion features are no longer separated from the host contract. Consequently, a convertible debt instrument will be accounted for as a single liability measured at its amortized cost, and convertible preferred stock will be accounted for as a single equity instrument measured at its historical cost as long as no other features require bifurcation and recognition as derivatives. On August 1, 2021, we early adopted this ASU. Our adoption of this ASU did not have any impact on our condensed consolidated financial statements or disclosures. • FASB ASU No. 2021-08, which requires that an acquirer recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606, as if it had originated the contracts. Prior to this ASU, an acquirer generally recognized contract assets and contract liabilities assumed that arose from contracts with customers at fair value on the acquisition date. On August 1, 2021, we early adopted this ASU. Our early adoption of this ASU did not have any impact on our condensed consolidated financial statements or disclosures.

Revenue Recognition

Revenue Recognition	6 Months Ended
	Jan. 31, 2022
Revenue from Contract with Customer [Abstract]
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). 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 Government Solutions segment and, to a lesser extent, certain location-based and messaging infrastructure contracts in our public safety and location technologies product line within our Commercial Solutions segment. For service-based contracts in our public safety and location technologies product line, 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 modems, solid-state and traveling wave tube amplifiers) and certain contracts for our solid-state, high-power RF 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: Three months ended January 31, Six months ended January 31, 2022 2021 2022 2021 United States U.S. government 27.1 % 44.2 % 28.6 % 38.8 % Domestic 47.6 % 33.9 % 48.0 % 37.6 % Total United States 74.7 % 78.1 % 76.6 % 76.4 % International 25.3 % 21.9 % 23.4 % 23.6 % Total 100.0 % 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. Included in domestic sales are sales to Verizon Communications Inc. ("Verizon"), which accounted for 11.1% and 11.4% of consolidated net sales for the three and six months ended January 31, 2022, respectively, and 10.0% and 11.1% of consolidated net sales for the three and six months ended January 31, 2021, 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 the three and six months ended January 31, 2022 and 2021. The following tables summarize our disaggregation of revenue consistent with information reviewed by our Chief Operating Decision Maker ("CODM") for the three and six months ended January 31, 2022 and 2021. 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: Three months ended January 31, 2022 Six months ended January 31, 2022 Commercial Solutions Government Solutions Total Commercial Solutions Government Solutions Total Geographical region and customer type U.S. government $ 12,254,000 20,297,000 $ 32,551,000 $ 23,288,000 44,432,000 $ 67,720,000 Domestic 50,563,000 6,757,000 57,320,000 101,783,000 12,092,000 113,875,000 Total United States 62,817,000 27,054,000 89,871,000 125,071,000 56,524,000 181,595,000 International 18,460,000 12,050,000 30,510,000 35,140,000 20,405,000 55,545,000 Total $ 81,277,000 39,104,000 $ 120,381,000 $ 160,211,000 76,929,000 $ 237,140,000 Contract type Firm fixed-price $ 81,155,000 32,212,000 $ 113,367,000 $ 159,875,000 62,594,000 $ 222,469,000 Cost reimbursable 122,000 6,892,000 7,014,000 336,000 14,335,000 14,671,000 Total $ 81,277,000 39,104,000 $ 120,381,000 $ 160,211,000 76,929,000 $ 237,140,000 Transfer of control Point in time $ 28,597,000 19,202,000 $ 47,799,000 $ 52,797,000 35,765,000 $ 88,562,000 Over time 52,680,000 19,902,000 72,582,000 107,414,000 41,164,000 148,578,000 Total $ 81,277,000 39,104,000 $ 120,381,000 $ 160,211,000 76,929,000 $ 237,140,000 Three months ended January 31, 2021 Six months ended January 31, 2021 Commercial Solutions Government Solutions Total Commercial Solutions Government Solutions Total Geographical region and customer type U.S. government $ 16,846,000 54,498,000 $ 71,344,000 $ 26,304,000 88,930,000 $ 115,234,000 Domestic 47,959,000 6,684,000 54,643,000 97,259,000 14,098,000 111,357,000 Total United States 64,805,000 61,182,000 125,987,000 123,563,000 103,028,000 226,591,000 International 23,020,000 12,285,000 35,305,000 46,064,000 23,855,000 69,919,000 Total $ 87,825,000 73,467,000 $ 161,292,000 $ 169,627,000 126,883,000 $ 296,510,000 Contract type Firm fixed-price $ 87,144,000 38,074,000 $ 125,218,000 $ 168,132,000 70,730,000 $ 238,862,000 Cost reimbursable 681,000 35,393,000 36,074,000 1,495,000 56,153,000 57,648,000 Total $ 87,825,000 73,467,000 $ 161,292,000 $ 169,627,000 126,883,000 $ 296,510,000 Transfer of control Point in time $ 37,135,000 26,535,000 $ 63,670,000 $ 66,806,000 49,566,000 $ 116,372,000 Over time 50,690,000 46,932,000 97,622,000 102,821,000 77,317,000 180,138,000 Total $ 87,825,000 73,467,000 $ 161,292,000 $ 169,627,000 126,883,000 $ 296,510,000 The timing of revenue recognition, billings and collections results in receivables, unbilled receivables and contract liabilities on our Condensed Consolidated Balance Sheet. 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 six months ended January 31, 2022 and 2021, respectively. 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 contract liability balance at July 31, 2021 and July 31, 2020, $35,517,000 and $24,320,000 was recognized as revenue during the six months ended January 31, 2022 and 2021, 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. Incremental costs to obtain or fulfill contracts with an amortization period greater than one year were not material. As commissions payable to our internal sales and marketing employees or contractors are contingent upon multiple factors, such commissions are not considered direct costs to obtain or fulfill a contract with a customer and are expensed as incurred in selling, general and administrative expenses on our Condensed Consolidated Statements of Operations. As for commissions payable to our third-party sales representatives related to long-term contracts, we do consider these types of commissions both direct and incremental costs to obtain and fulfill such contracts. Therefore, such types of commissions are included in total estimated costs at completion for such contracts and expensed over time through cost of sales on our Condensed Consolidated Statements of Operations.

Earnings Per Share

Earnings Per Share	6 Months Ended
	Jan. 31, 2022
Earnings Per Share [Abstract]
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, settlement of escrow and earn-out arrangements related to our acquisition of UHP and the assumed conversion of Convertible Preferred Stock, if dilutive, outstanding during each respective period. 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 three or six months ended January 31, 2022 or 2021. See Note (18) - " Stockholders’ Equity " for more information. Weighted average stock options, RSUs and restricted stock outstanding of 1,467,000 and 1,496,000 for the three months ended January 31, 2022 and 2021, respectively, and 1,498,000 and 1,515,000 for the six months ended January 31, 2022 and 2021, respectively, were not included in our diluted EPS calculation because their effect would have been anti-dilutive. Our EPS calculations exclude 273,000 and 237,000 weighted average performance shares outstanding for the three months ended January 31, 2022 and 2021, respectively, and 258,000 and 235,000 for the six months ended January 31, 2022 and 2021, 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 477,000 and 409,000 related to our acquisition of UHP in March 2021 were not included in our diluted EPS calculation for the three and six months ended January 31, 2022, respectively, because their effect would have been anti-dilutive. Weighted average common shares of 4,158,000 and 2,358,000 underlying the assumed conversion of Convertible Preferred Stock, on an if-converted basis, were not included in our diluted EPS calculation for the three and six months ended January 31, 2022, respectively, because their effect would have been anti-dilutive. As a result, the numerator for our basic and diluted EPS calculation for the three and six months ended January 31, 2022 is the respective net loss attributable to common stockholders. The following table reconciles the numerators and denominators used in the basic and diluted EPS calculations: Three months ended January 31, Six months ended January 31, 2022 2021 2022 2021 Numerator: Net (loss) income $ (21,874,000) 4,205,000 $ (27,858,000) (81,635,000) Convertible preferred stock issuance costs — — (4,007,000) — Establishment of initial convertible preferred stock purchase option liability — — (1,005,000) — Dividend on convertible preferred stock (1,632,000) — (1,867,000) — Net loss attributable to common stockholders $ (23,506,000) 4,205,000 $ (34,737,000) (81,635,000) Denominator: Denominator for basic calculation 26,472,000 25,337,000 26,449,000 25,321,000 Effect of dilutive securities: Stock-based awards — 83,000 — — Denominator for diluted calculation 26,472,000 25,420,000 26,449,000 25,321,000 As discussed further in Note (17) - " Convertible Preferred Stock ," the Convertible Preferred Stock issued in October 2021 represents a "participating security" as defined in ASC 260. As a result, our EPS calculations for the three and six months ended January 31, 2022 were based on the two-class method. Given the net loss attributable to common stockholders for the three and six months ended January 31, 2022, there was no impact of applying the two-class method to our reported basic or diluted earnings per common share.

Credit Facility

Credit Facility	6 Months Ended

Line of Credit Facility [Abstract]
Credit Facility	Credit Facility On October 31, 2018, we entered into a First Amended and Restated Credit Agreement (the "Credit Facility") with a syndicate of lenders. The Credit Facility provides a senior secured loan facility of up to $550,000,000 consisting of: (i) a revolving loan facility ("Revolving Loan Facility") with a borrowing limit of $300,000,000; (ii) an accordion feature allowing us to make a request to borrow up to an additional $250,000,000 subject to the satisfaction of specified conditions, including approval by our lenders; (iii) a $35,000,000 letter of credit sublimit; and (iv) a swingline loan credit sublimit of $25,000,000. The Credit Facility matures on October 31, 2023 (the "Revolving Maturity Date"). If we issue new unsecured debt in excess of $5,000,000 with a maturity date that is less than 91 days from October 31, 2023, the Revolving Maturity Date would automatically accelerate so that it would be 91 days earlier than the maturity date of the new unsecured debt. As of January 31, 2022, the amount outstanding under our Credit Facility was $114,500,000, which is reflected in the non-current portion of long-term debt on our Condensed Consolidated Balance Sheet. At January 31, 2022, we had $1,007,000 of standby letters of credit outstanding under our Credit Facility related to guarantees of future performance on certain customer contracts and no outstanding commercial letters of credit. During the six months ended January 31, 2022, we had outstanding balances under the Credit Facility ranging from $100,000,000 to $212,000,000. As of January 31, 2022, total net deferred financing costs related to the Credit Facility were $1,419,000 and are being amortized over the term of our Credit Facility through October 31, 2023. Interest expense related to our Credit Facility, including amortization of deferred financing costs, recorded during the three months ended January 31, 2022 and 2021 was $981,000 and $1,414,000, respectively. Interest expense related to our Credit Facility, including amortization of deferred financing costs, recorded during the six months ended January 31, 2022 and 2021 was $2,474,000 and $2,525,000, respectively. Our blended interest rate approximated 3.40% and 2.73%, respectively, for the three months ended January 31, 2022 and 2021 and approximated 3.10% and 2.71%, respectively, for the six months ended January 31, 2022 and 2021. Borrowings under the Credit Facility shall be either: (i) Alternate Base Rate borrowings, which bear interest from the applicable borrowing date at a rate per annum equal to (x) the greatest of (a) the Prime Rate (as defined) in effect on such day, (b) the Federal Funds Effective Rate (as defined) in effect on such day plus 1/2 of 1.00% per annum and (c) the Adjusted LIBO Rate (as defined) on such day (or, if such day is not a business day, the immediately preceding business day) plus 1.00% per annum, plus (y) the Applicable Rate (as defined), or (ii) Eurodollar borrowings, which bear interest from the applicable borrowing date at a rate per annum equal to (x) the Adjusted LIBO Rate for such interest period plus (y) the Applicable Rate. Determination of the Applicable Rate is based on a pricing grid that is dependent upon our Secured Leverage Ratio (as defined) as of the end of each fiscal quarter for which consolidated financial statements have been most recently delivered. The Credit Facility contains customary representations, warranties and affirmative covenants. The Credit Facility also 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 Credit Facility also contains certain financial covenants and 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. The Credit Facility provides for, among other things: (i) no scheduled payments of principal until maturity; (ii) a maximum Secured Leverage Ratio of 3.75x trailing twelve months ("TTM") Adjusted Earnings Before Interest, Taxes, Depreciation and Amortization ("Adjusted EBITDA") and a Maximum Total Leverage Ratio of 4.50x TTM Adjusted EBITDA, each with no step downs; and (iii) a Minimum Interest Expense Coverage Ratio of 3.25x TTM Adjusted EBITDA. As of January 31, 2022, our Secured Leverage Ratio was 1.95x TTM Adjusted EBITDA compared to the maximum allowable Secured Leverage Ratio of 3.75x TTM Adjusted EBITDA. Our Interest Expense Coverage Ratio as of January 31, 2022 was 11.91x TTM Adjusted EBITDA compared to the Minimum Interest Expense Coverage Ratio of 3.25x TTM Adjusted EBITDA. Given our expected future business performance, we anticipate maintaining compliance with the terms and financial covenants in our Credit Facility for the foreseeable future. The obligations under the Credit Facility are guaranteed by certain of our domestic and foreign subsidiaries (the "Guarantors"). As collateral security under the Credit Facility and the guarantees thereof, we and the Guarantors have granted to the administrative agent, for the benefit of the lenders, a lien on, and first priority security interest in, substantially all of our tangible and intangible assets. On December 6, 2018, we entered into an amendment to the Credit Facility to provide for a mechanism to replace the LIBO Rate for Eurodollar borrowings with an alternative benchmark interest rate, should the LIBO Rate generally become unavailable in the future on an other-than-temporary basis. On January 14, 2021, we entered into a further amendment of the Credit Facility to update the LIBO Rate replacement mechanism language and other definitional items. On July 30, 2021, we entered into an amendment to incorporate certain foreign subsidiaries as loan parties and guarantors into the Credit Facility and added certain definitional items. Capitalized terms used but not defined herein have the meanings set forth for such terms in the Credit Facility, which has been documented and filed with the SEC.

Leases

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 January 31, 2022, 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: Three months ended January 31, Six months ended January 31, 2022 2021 2022 2021 Finance lease expense: Amortization of ROU assets $ 3,000 16,000 $ 7,000 28,000 Interest on lease liabilities — 1,000 — 2,000 Operating lease expense 2,940,000 2,861,000 5,864,000 5,349,000 Short-term lease expense 117,000 255,000 211,000 502,000 Variable lease expense 1,142,000 1,190,000 2,318,000 2,154,000 Sublease income (16,000) (16,000) (33,000) (33,000) Total lease expense $ 4,186,000 4,307,000 $ 8,367,000 8,002,000 Additional information related to leases is as follows: Six months ended January 31, 2022 2021 Cash paid for amounts included in the measurement of lease liabilities: Operating leases - Operating cash outflows $ 5,850,000 $ 5,050,000 Finance leases - Operating cash outflows — 2,000 Finance leases - Financing cash outflows 11,000 28,000 ROU assets obtained in the exchange for lease liabilities (non-cash): Operating leases $ 14,812,000 $ 25,663,000 The following table is a reconciliation of future cash flows relating to operating and financing lease liabilities presented on our Condensed Consolidated Balance Sheet as of January 31, 2022: Operating Finance Total Remainder of fiscal 2022 $ 5,985,000 5,000 $ 5,990,000 Fiscal 2023 10,090,000 4,000 10,094,000 Fiscal 2024 8,856,000 — 8,856,000 Fiscal 2025 8,301,000 — 8,301,000 Fiscal 2026 6,826,000 — 6,826,000 Thereafter 29,240,000 — 29,240,000 Total future undiscounted cash flows 69,298,000 9,000 69,307,000 Less: Present value discount 10,875,000 1,000 10,876,000 Lease liabilities $ 58,423,000 8,000 $ 58,431,000 Weighted-average remaining lease terms (in years) 8.92 1.01 Weighted-average discount rate 3.40% 6.68% We lease our Melville, New York production facility from a partnership controlled by the non-executive Chairman of our Board of Directors.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes At January 31, 2022 and July 31, 2021, total unrecognized tax benefits were $9,521,000 and $9,172,000, respectively, including interest of $223,000 and $163,000, respectively. At January 31, 2022 and July 31, 2021, $3,204,000 and $2,717,000, respectively, of our unrecognized tax benefits were recorded as non-current income taxes payable on our Condensed Consolidated Balance Sheets. The remaining unrecognized tax benefits of $6,317,000 and $6,455,000 at January 31, 2022 and July 31, 2021, respectively, were presented as an offset to the associated non-current deferred tax assets on our Condensed Consolidated Balance Sheets. Of the total unrecognized tax benefits, $8,679,000 and $8,408,000 at January 31, 2022 and July 31, 2021, 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. Unrecognized tax benefits result from income tax positions taken or expected to be taken on our income tax returns for which a tax benefit has not been recorded in our condensed consolidated financial statements. We do not expect that there will be any significant changes to our total unrecognized tax benefits within the next twelve months. Our U.S. federal income tax returns for fiscal 2018 through 2020 are subject to potential future Internal Revenue Service ("IRS") audit. None of our state income tax returns prior to fiscal 2017 are subject to audit. Future tax assessments or settlements could have a material adverse effect on our consolidated results of operations and financial condition.

Share-based Payment Arrangement [Abstract]
Stock-Based Compensation	Stock-Based Compensation Overview We issue stock-based awards to certain of our employees and our Board of Directors pursuant to our 2000 Stock Incentive Plan, as amended and/or restated from time to time (the "Plan") 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 condensed consolidated financial statements. The 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, excluding our non-executive Chairman, are eligible to receive non-discretionary grants of stock-based awards, subject to certain limitations. As of January 31, 2022, the aggregate number of shares of common stock which may be issued, pursuant to the Plan, may not exceed 10,962,500. 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 January 31, 2022, we had granted stock-based awards pursuant to the Plan representing the right to purchase and/or acquire an aggregate of 9,644,199 shares (net of 4,838,965 expired and canceled awards), of which an aggregate of 7,591,659 have been exercised or settled. As of January 31, 2022, the following stock-based awards, by award type, were outstanding: January 31, 2022 Stock options 1,005,935 Performance shares 341,652 RSUs, restricted stock and share units 704,953 Total 2,052,540 Our ESPP provides for the issuance of up to 1,050,000 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 January 31, 2022, we have cumulatively issued 916,447 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 Condensed Consolidated Statements of Operations: Three months ended January 31, Six months ended January 31, 2022 2021 2022 2021 Cost of sales $ 76,000 59,000 $ 149,000 132,000 Selling, general and administrative expenses 1,836,000 1,158,000 2,608,000 1,700,000 Research and development expenses 71,000 70,000 147,000 154,000 Stock-based compensation expense 1,983,000 1,287,000 2,904,000 1,986,000 CEO transition costs related to equity-classified stock-based awards 7,388,000 — 7,388,000 — Total stock-based compensation expense before income tax benefit 9,371,000 1,287,000 10,292,000 1,986,000 Estimated income tax benefit (1,030,000) (280,000) (1,223,000) (424,000) Net stock-based compensation expense $ 8,341,000 1,007,000 $ 9,069,000 1,562,000 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 January 31, 2022, unrecognized stock-based compensation of $10,024,000, net of estimated forfeitures of $895,000, is expected to be recognized over a weighted average period of 3.3 years. Total stock-based compensation capitalized and included in ending inventory at both January 31, 2022 and July 31, 2021 was $48,000. There are no liability-classified stock-based awards outstanding as of January 31, 2022 or July 31, 2021. Of the selling, general and administrative expenses included in the table above, for both the three and six months ended January 31, 2022, $827,000 represents the amortization of stock-based compensation related to the retirement, in December 2021, of three, long-standing members of our Board of Directors. Stock-based compensation expense, by award type, is summarized as follows: Three months ended January 31, Six months ended January 31, 2022 2021 2022 2021 Stock options $ 364,000 97,000 $ 442,000 217,000 Performance shares 364,000 443,000 713,000 665,000 RSUs, restricted stock and share units 1,200,000 699,000 1,639,000 1,005,000 ESPP 55,000 48,000 110,000 99,000 Stock-based compensation expense 1,983,000 1,287,000 2,904,000 1,986,000 CEO transition costs related to equity-classified stock-based awards 7,388,000 — 7,388,000 — Total stock-based compensation expense before income tax benefit 9,371,000 1,287,000 10,292,000 1,986,000 Estimated income tax benefit (1,030,000) (280,000) (1,223,000) (424,000) Net stock-based compensation expense $ 8,341,000 1,007,000 $ 9,069,000 1,562,000 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 Condensed Consolidated Balance Sheet as of January 31, 2022 and July 31, 2021. 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 (56,250) 27.59 Exercised (1,220) 17.88 Outstanding at October 31, 2021 1,015,965 25.66 Expired/canceled (10,030) 27.14 Outstanding at January 31, 2022 1,005,935 $ 25.65 2.46 $ 716,000 Exercisable at January 31, 2022 888,575 $ 26.68 1.68 $ 429,000 Vested and expected to vest at January 31, 2022 999,147 $ 25.70 2.42 $ 699,000 Stock options outstanding as of January 31, 2022 have exercise prices ranging from $17.88 - $33.94, 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 six months ended January 31, 2022 was $7,000. There were no stock options exercised during the six months ended January 31, 2021. Performance Shares, RSUs, Restricted Stock and Share Unit Awards The following table summarizes the Plan's activity relating to performance shares, RSUs, restricted stock and share units: Awards Weighted Average Aggregate Intrinsic Value Outstanding at July 31, 2021 1,068,370 $ 21.93 Granted 228,161 26.81 Settled (190,310) 23.97 Canceled/Forfeited (40,880) 23.15 Outstanding at October 31, 2021 1,065,341 22.56 Granted 187,658 23.35 Settled (191,238) 22.47 Canceled/Forfeited (15,156) 21.88 Outstanding at January 31, 2022 1,046,605 $ 22.73 $ 21,277,000 Vested at January 31, 2022 444,490 $ 22.12 $ 9,036,000 Vested and expected to vest at January 31, 2022 1,009,648 $ 22.71 $ 20,526,000 The total intrinsic value relating to fully-vested awards settled during the three and six months ended January 31, 2022 was $4,569,000 and $9,464,000, respectively. The total intrinsic value relating to fully-vested awards settled during the three and six months ended January 31, 2021 was $9,000 and $2,905,000, 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 January 31, 2022, 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. RSUs and restricted stock granted to non-employee directors prior to July 31, 2019 had a vesting period of three years 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. After July 31, 2019, such awards have a vesting period of five years. Also, restricted stock granted to our non-executive Chairman of the Board of Directors, pursuant to his Senior Technology Advisor consulting agreement, vests 1/12 on the date of grant and in eleven equal monthly installments thereafter. RSUs granted to employees 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. Also, certain RSUs granted to our newly appointed CEO, pursuant to his employment agreement, vest over 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. Cumulatively, through January 31, 2022, 956,576 share units granted have been settled. The fair value of performance shares, RSUs, restricted stock and share units 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 granted since fiscal 2013 are entitled to dividend equivalents unless forfeited before vesting occurs. Share units granted since fiscal 2014 are 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 the three and six months ended January 31, 2022, we accrued $129,000 and $217,000, respectively, of dividend equivalents (net of forfeitures) and paid out $210,000 and $525,000, respectively. Accrued dividend equivalents were recorded as a reduction to retained earnings. As of January 31, 2022 and July 31, 2021, accrued dividend equivalents were $577,000 and $884,000, respectively.

Segment Reporting [Abstract]
Segment Information	Segment InformationReportable 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. In connection with our CEO leadership transition, our new CEO is currently evaluating his management approach to the business. At the moment, we are currently managing our business through the following reportable operating segments: Our Commercial Solutions segment offers satellite ground station technologies (such as modems and amplifiers) and public safety and location technologies (such as 911 call routing, 911 call handling and mapping solutions) to commercial customers and smaller government customers, such as state and local governments. This segment also serves certain large government customers (including the U.S. government) that have requirements for off-the-shelf commercial equipment. Our Government Solutions segment provides tactical satellite-based networks and ongoing support for complicated communications networks and troposcatter systems and solid-state, high-power amplifiers to large government end-users (including those of foreign countries), large international customers and domestic prime contractors. 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 Commercial Solutions and Government Solutions segments do not consider any allocation of indirect expense, or any of the following: income taxes, interest (income) and other, change in fair value of the convertible preferred stock purchase option liability, write-off of deferred financing costs, interest expense, amortization of stock-based compensation, amortization of intangibles, depreciation expense, estimated contract settlement costs, settlement of intellectual property litigation, acquisition plan expenses, restructuring costs, COVID-19 related costs, strategic emerging technology costs (for next-generation satellite technology), facility exit costs, CEO transition costs, proxy solicitation costs, strategic alternatives analysis 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 Commercial Solutions and Government Solutions 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 (as such term is defined in our 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: Three months ended January 31, 2022 Commercial Solutions Government Solutions Unallocated Total Net sales $ 81,277,000 39,104,000 — $ 120,381,000 Operating income (loss) $ 4,552,000 (196,000) (28,946,000) $ (24,590,000) Net income (loss) $ 4,565,000 (108,000) (26,331,000) $ (21,874,000) Benefit from income taxes (127,000) — (3,149,000) (3,276,000) Interest (income) and other 108,000 (88,000) (50,000) (30,000) Change in fair value of convertible preferred stock purchase option liability — — (398,000) (398,000) Interest expense 6,000 — 982,000 988,000 Amortization of stock-based compensation — — 1,983,000 1,983,000 Amortization of intangibles 4,260,000 1,089,000 — 5,349,000 Depreciation 1,944,000 339,000 51,000 2,334,000 CEO transition costs — — 13,554,000 13,554,000 Proxy solicitation costs — — 9,086,000 9,086,000 Restructuring costs 1,696,000 30,000 — 1,726,000 COVID-19 related costs — 355,000 — 355,000 Adjusted EBITDA $ 12,452,000 1,617,000 (4,272,000) $ 9,797,000 Purchases of property, plant and equipment $ 4,073,000 1,100,000 — $ 5,173,000 Total assets at January 31, 2022 $ 740,126,000 228,018,000 26,710,000 $ 994,854,000 Three months ended January 31, 2021 Commercial Solutions Government Solutions Unallocated Total Net sales $ 87,825,000 73,467,000 — $ 161,292,000 Operating income (loss) $ 9,371,000 5,460,000 (9,429,000) $ 5,402,000 Net income (loss) $ 9,283,000 5,695,000 (10,773,000) $ 4,205,000 Provision for (benefit from) income taxes 217,000 (286,000) (86,000) (155,000) Interest (income) and other (129,000) 47,000 16,000 (66,000) Interest expense — 4,000 1,414,000 1,418,000 Amortization of stock-based compensation — — 1,287,000 1,287,000 Amortization of intangibles 4,286,000 509,000 — 4,795,000 Depreciation 1,934,000 443,000 80,000 2,457,000 Acquisition plan expenses — — 3,357,000 3,357,000 Restructuring costs 601,000 — — 601,000 COVID-19 related costs — 160,000 — 160,000 Adjusted EBITDA $ 16,192,000 6,572,000 (4,705,000) $ 18,059,000 Purchases of property, plant and equipment $ 1,575,000 1,221,000 — $ 2,796,000 Total assets at January 31, 2021 $ 672,209,000 240,618,000 33,768,000 $ 946,595,000 Six months ended January 31, 2022 Commercial Solutions Government Solutions Unallocated Total Net sales $ 160,211,000 76,929,000 — $ 237,140,000 Operating income (loss) $ 6,755,000 (1,610,000) (36,250,000) $ (31,105,000) Net income (loss) $ 6,620,000 (1,259,000) (33,219,000) $ (27,858,000) Provision for (benefit from) income taxes 46,000 (631,000) (4,744,000) (5,329,000) Interest (income) and other 83,000 166,000 (60,000) 189,000 Change in fair value of convertible preferred stock purchase option liability — — (702,000) (702,000) Interest expense 6,000 114,000 2,475,000 2,595,000 Amortization of stock-based compensation — — 2,904,000 2,904,000 Amortization of intangibles 8,520,000 2,178,000 — 10,698,000 Depreciation 3,752,000 720,000 103,000 4,575,000 CEO transition costs — — 13,554,000 13,554,000 Proxy solicitation costs — 11,248,000 11,248,000 Restructuring costs 2,509,000 (71,000) — 2,438,000 COVID-19 related costs — 1,029,000 — 1,029,000 Adjusted EBITDA $ 21,536,000 2,246,000 (8,441,000) $ 15,341,000 Purchases of property, plant and equipment $ 6,768,000 2,043,000 — $ 8,811,000 Total assets at January 31, 2022 $ 740,126,000 228,018,000 26,710,000 $ 994,854,000 Six months ended January 31, 2021 Commercial Solutions Government Solutions Unallocated Total Net sales $ 169,627,000 126,883,000 — $ 296,510,000 Operating income (loss) $ 18,121,000 8,045,000 (106,480,000) $ (80,314,000) Net income (loss) $ 17,598,000 8,386,000 (107,619,000) $ (81,635,000) Provision for (benefit from) income taxes 556,000 (412,000) (2,538,000) (2,394,000) Interest (income) and other (33,000) 7,000 26,000 — Interest expense — 64,000 3,651,000 3,715,000 Amortization of stock-based compensation — — 1,986,000 1,986,000 Amortization of intangibles 8,573,000 1,788,000 — 10,361,000 Depreciation 3,930,000 846,000 233,000 5,009,000 Acquisition plan expenses (1,052,000) — 95,592,000 94,540,000 Restructuring costs 601,000 — 601,000 COVID-19 related costs — 160,000 — 160,000 Adjusted EBITDA $ 30,173,000 10,839,000 (8,669,000) $ 32,343,000 Purchases of property, plant and equipment $ 1,964,000 1,642,000 80,000 $ 3,686,000 Total assets at January 31, 2021 $ 672,209,000 240,618,000 33,768,000 $ 946,595,000 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. During the three and six months ended January 31, 2021, we recorded $3,357,000 and $94,540,000, respectively of acquisition plan expenses, most of which were recorded in our unallocated expenses. See Note (2) - "Acquisitions" for further information. There were no such charges recorded in the three and six months ended January 31, 2022. During the three and six months ended January 31, 2022, we incurred $9,086,000 and $11,248,000, respectively, 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 initiated by a shareholder during the first quarter of fiscal 2022. Also, during the three and six months ended January 31, 2022, we expensed $13,554,000 of CEO transition costs. See Note (1) - " General - CEO Transition Costs " for a further discussion. During the three and six months ended January 31, 2022, our Commercial Solutions segment recorded $1,696,000 and $2,509,000, respectively, of restructuring costs to streamline our operations, including costs related to the ongoing relocation of certain of our satellite earth station production facilities to a new 146,000 square foot facility in Chandler, Arizona. Similar restructuring costs of $601,000 were incurred during three and six months ended January 31, 2021. In addition, during the three and six months ended January 31, 2022, our Government Solutions segment recorded $355,000 and $1,029,000, respectively of incremental operating costs related to our antenna facility located in the United Kingdom due to the impact of the COVID-19 pandemic. Similar incremental operating costs of $160,000 were incurred during three and six months ended January 31, 2021. Interest expense in the tables above primarily relates to our Credit Facility, and includes the amortization of deferred financing costs. See Note (10) - " Credit Facility " for further discussion. Interest expense for the six months ended January 31, 2021 includes $1,178,000 of incremental interest expense related to a now terminated financing commitment letter, as discussed in more detail in Note (2) - " Acquisitions ." Intersegment sales for the three months ended January 31, 2022 and 2021 by the Commercial Solutions segment to the Government Solutions segment were $934,000 and $944,000, respectively. Intersegment sales for the six months ended January 31, 2022 and 2021 by the Commercial Solutions segment to the Government Solutions segment were $2,066,000 and $1,795,000, respectively. There were nominal sales by the Government Solutions segment to the Commercial Solutions segment for these periods. All intersegment sales are eliminated in consolidation and are excluded from the tables above. Unallocated assets at January 31, 2022 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.

Goodwill [Abstract]
Goodwill	Goodwill The following table represents goodwill by reportable operating segment, including the changes in the net carrying value of goodwill during the six months ended January 31, 2022: Commercial Solutions Government Solutions Total Balance as of July 31, 2021 $ 270,389,000 77,309,000 $ 347,698,000 UHP acquisition (6,000) — (6,000) Balance as of January 31, 2022 $ 270,383,000 77,309,000 $ 347,692,000 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. On August 1, 2021 (the first day of our fiscal 2022), we performed our annual 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 August 1, 2021 total public market capitalization and assessed implied control premiums based on our common stock price of $24.97 as of August 1, 2021. Based on our quantitative evaluation, we determined that our Commercial Solutions and Government Solutions reporting units had estimated fair values in excess of their carrying values of at least 22.7% and 94.1%, respectively, and concluded that our goodwill was not impaired and that neither of our two reporting units was at risk of failing the quantitative assessment. It is possible that, during the remainder of fiscal 2022 or beyond, business conditions (both in the U.S. and internationally) could deteriorate from the current state, our current or prospective customers could materially postpone, reduce or even forgo purchases of our products and services to a greater extent than we currently anticipate, or our common stock price could fluctuate. Such fluctuation could be caused by uncertainty about the severity and length of the COVID-19 pandemic, and its impact on global activity. A significant decline in our customers' spending that is greater than we anticipate or a shift in funding priorities may also have a negative effect on future orders, sales, income and cash flows and we might be required to perform a quantitative assessment during fiscal 2022 or beyond. If assumed net sales and cash flow projections are not achieved in future periods or our common stock price significantly declines from current levels, our Commercial Solutions and Government Solutions reporting units could be at risk of failing the quantitative assessment and goodwill assigned to the respective reporting units could be impaired. In any event, we are required to perform the next annual goodwill impairment analysis on August 1, 2022 (the start of our fiscal 2023). Also, as disclosed in Note (14) - "Segment Information," our new CEO is currently evaluating his management approach to the business. 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 six months ended January 31, 2022 and 2021 was $10,698,000 and $10,361,000, respectively. The estimated amortization expense consists of the following for the fiscal years ending July 31: 2022 $ 21,589,000 2023 21,781,000 2024 21,154,000 2025 21,041,000 2026 19,888,000 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 believe that the carrying values of our net intangible assets were recoverable as of January 31, 2022. 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.

Convertible Preferred Stock

Convertible Preferred Stock	6 Months Ended

Temporary Equity Disclosure [Abstract]
Convertible Preferred Stock	Convertible Preferred StockOn October 18, 2021, we entered into a Subscription Agreement (the “Subscription Agreement”) with certain affiliates and related funds of White Hat Capital Partners LP and Magnetar Capital LLC (collectively, the “Investors”), relating to the issuance and sale of up to 125,000 shares of a new series of the Company's Series A Convertible Preferred Stock, par value $0.10 per share (the “Convertible Preferred Stock”), for an aggregate purchase price of up to $125,000,000, or $1,000 per share. On October 19, 2021 (the “Initial Closing Date”), pursuant to the terms of the Subscription Agreement, the Investors purchased an aggregate of 100,000 shares of Convertible Preferred Stock (the “Initial Issuance”) for an aggregate purchase price of $100,000,000. The Investors have a one-time option exercisable at any time on or prior to March 31, 2023 to purchase additional shares of Convertible Preferred Stock for an aggregate purchase price of $25,000,000. This purchase option is commonly referred to as a “Green Shoe” and together with the Initial Issuance, is collectively referred to as the “Issuance.” The initial conversion price for the shares issued in the Initial Issuance is $24.50, subject to an increase in the conversion price to $26.00 upon the achievement of $76.0 million of Adjusted EBITDA (as defined in the Subscription Agreement) for our fiscal 2022 year, and the initial conversion price for the Green Shoe is $32.00. The 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 Convertible Preferred Stock initially had a liquidation preference of $1,000 per share with each share entitled to a cumulative dividend (the “Dividend”) at the rate of 6.5% per annum, compounding quarterly, paid-in-kind or paid in cash, at our election. For any quarter in which we elect not to pay the Dividend in cash with respect to a share of Convertible Preferred Stock, such Dividend becomes part of the liquidation preference of such share. In addition, no dividend or other distribution on our common stock in excess of our $0.10 per share per quarter will be declared or paid on the common stock unless, at the time of such declaration and payment, an equivalent dividend or distribution is declared and paid on the 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 shares of the Convertible Preferred Stock. Such Participating Dividend results in the Convertible Preferred Stock meeting the definition of a "participating security" for purposes of our earnings per share calculations. The Convertible Preferred Stock is convertible into shares of common stock at the option of the holders thereof at or following the earlier to occur of (a) the filing of our Annual Report on Form 10-K for the fiscal year ending July 31, 2022 but no later than October 19, 2022, or (b) immediately prior to (and conditioned upon) the consummation of a Change of Control. At any time after October 19, 2024, we have the right to mandate the conversion of the Convertible Preferred Stock, subject to certain restrictions, based on the price of the common stock in the preceding thirty trading days. Holders of the Convertible Preferred Stock are entitled to vote with the holders of the common stock on an as-converted basis, as well as 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 Convertible Preferred Stock, authorizations or issuances of securities of the Company, the payment of dividends other than dividends on common stock in the ordinary course consistent with past practice on a quarterly basis in an amount not to exceed our current dividend rate of $0.10 per share per quarter, related party transactions, repurchases or redemptions of securities of the Company (other than the repurchase of up to $25,000,000 of shares of common stock), dispositions of businesses or assets, the incurrence of certain indebtedness and certain amendments or extensions of our existing Credit Facility. Holders will have the right to require the Company to repurchase such holder's Convertible Preferred Stock on a date occurring either (a) on or after October 19, 2026 (the “Optional Repurchase Trigger Date”) at a price equal to the liquidation preference or (b) in connection with a conversion of Convertible Preferred Stock, pursuant to which the number of shares of common stock issuable upon such conversion would exceed 19.99% of the issued and outstanding shares of common stock as of October 18, 2021 (such excess shares, "Excess Conversion Shares"), at any time after the date that is 91 days after the maturity date of the Company's existing Credit Facility, at a price per share equal to the number of Excess Conversion Shares multiplied by the Last Reported Sales Price (as defined) of common stock on the applicable conversion date. In addition, each holder will have the right to cause the Company to repurchase its shares of Convertible Preferred Stock in connection with a Change of Control, at a price equal to the liquidation preference. We determined that our obligation to issue the Green Shoe at any time on or prior to March 31, 2023 meets the definition of a freestanding financial instrument that should be accounted for as a liability. As such, we established an initial convertible preferred stock purchase option liability of $1,005,000 and reduced the proceeds from the Initial Issuance by such amount. The liability will be remeasured to its estimated fair value each reporting period until such instrument is exercised or expires. Changes in its estimated fair value are recognized as a non-cash charge or benefit and presented on the condensed consolidated statement of operations. The estimated fair value of the convertible preferred stock purchase option liability was $303,000 as of January 31, 2022. During the three and six months ended January 31, 2022, we recorded benefits of $398,000 and $702,000, respectively for the remeasurement of the convertible preferred stock purchase option liability. 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 have classified the 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 Initial Issuance, we recorded the Convertible Preferred Stock, net of issuance costs of $4,007,000 and net of the portion of such proceeds allocated to the convertible preferred stock purchase option liability described above, which resulted in an initial carrying value of the Convertible Preferred Stock less than its initial redemption value of $100,000,000. We have elected to adjust the carrying value of the Convertible Preferred Stock to its current redemption value of $101,867,000, which includes $1,318,000 of dividends paid in kind and $549,000 of accumulated and unpaid dividends. As such, an adjustment of $6,879,000 to increase the carrying value of the Convertible Preferred Stock was recorded against retained earnings during the six months ended January 31, 2022.

Stockholders' Equity Note [Abstract]
Stockholders' Equity	Stockholders’ Equity Sale of Common Stock On March 3, 2021, in connection with our acquisition of UHP, we filed a shelf registration statement with the SEC for the sale by the selling stockholder of UHP of up to 1,381,567 shares of our common stock. See Note (2) - " Acquisitions - UHP Networks Inc ." for further information. Common Stock Repurchase Program On September 29, 2020, our Board of Directors authorized a new $100,000,000 stock repurchase program, which replaced our prior program. The new $100,000,000 stock repurchase program has no time restrictions and repurchases may be made from time to time in open-market or privately negotiated transactions, or by other means in accordance with federal securities laws. There were no repurchases of our common stock during the six months ended January 31, 2022 or 2021. Common Stock Dividends Since September 2010, we have paid quarterly dividends pursuant to an annual targeted dividend amount that was established by our Board of Directors. On October 4, 2021 and December 9, 2021, our Board of Directors declared a dividend of $0.10 per common share, which were paid on November 12, 2021 and February 18, 2022, respectively. On March 10, 2022, our Board of Directors declared a dividend of $0.10 per common share, payable on May 20, 2022 to stockholders of record at the close of business on April 20, 2022. Future dividends remain subject to compliance with financial covenants under our Credit Facility, as well as Board approval and certain voting rights of holders of our Series A Convertible Preferred Stock.

Fair Value Disclosures [Abstract]
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 and accrued expenses) approximate their fair values due to their short-term maturities. The fair value of our Credit Facility that we entered into on October 31, 2018 approximates its carrying amount due to its variable interest rate and pricing grid that is dependent upon our leverage ratio as of the end of each fiscal quarter. The stock purchase agreement for the acquisition of UHP provides for a contingent earn-out payment of up to $9,000,000, if specified sales milestones are reached during a defined period ending September 30, 2022. The earn-out is accounted for as a contingent consideration liability to be recorded at its fair value. See Note (2) - " Acquisitions " for more information regarding the estimated fair value of the earn-out. As of January 31, 2022 and July 31, 2021, other than the financial instruments discussed above, we had no other significant assets or liabilities included in our Condensed Consolidated Balance Sheets recorded at fair value, as such term is defined by FASB ASC 820.

Legal Proceedings and Other Matters	Legal Proceedings and Other Matters Settled Litigation Related to the Convertible Preferred Stock Issuance On October 25, 2021, Anthony Franchi (the “Plaintiff”) brought a putative class action in the Court of Chancery of the State of Delaware against the Company's current directors, the Company, White Hat Capital Partners LP (“White Hat”) and Magnetar Capital LLC (“Magnetar”), which was amended on November 1, 2021. On November 10, 2021, the parties filed a Stipulation and Proposed Order in the Franchi matter, pursuant to which, among other things, the parties agreed, and the court approved, that the Plaintiff’s claims that the Company's preliminary proxy omitted material information regarding the White Hat and Magnetar investments would be dismissed with prejudice and plaintiff’s claims that such investments included an implied voting agreement in connection with the 2021 Annual Stockholder Meeting would be dismissed without prejudice. While we disputed all of Plaintiff’s allegations and believed them to be without merit, we believed that entering into the aforementioned Stipulation and Proposed Order would avoid unnecessary litigation and is in the best interests of the Company's stockholders. The Company remains subject to certain pending liabilities and obligations in connection with the Stipulation and Proposed Order, which if not agreed to or resolved with Plaintiff, may result in future litigation. We do not believe the ultimate resolution of these matters will result in a material adverse effect on our consolidated results of operations and financial condition. 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 agree 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. Although the ultimate outcome of litigation is difficult to accurately predict, we believe that the outcome of these other pending and threatened actions will not have a material adverse effect on our consolidated financial condition or results of operations.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Principles of Consolidation	The accompanying condensed consolidated financial statements of Comtech Telecommunications Corp. and its subsidiaries ("Comtech," "we," "us," or "our") as of and for the three and six months ended January 31, 2022 and 2021 are unaudited. In the opinion of management, the information furnished reflects all material adjustments (which include normal recurring adjustments) necessary for a fair presentation of the results for the unaudited interim periods. Our results of operations for such periods are not necessarily indicative of the results of operations to be expected for the full fiscal year. The preparation of our condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires us 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 condensed consolidated financial statements, and the reported amounts of net sales and expenses during the reported period. Actual results may differ from those estimates. Our condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements, filed with the Securities and Exchange Commission ("SEC"), for the fiscal year ended July 31, 2021 and the notes thereto contained in our Annual Report on Form 10-K, and all of our other filings with the SEC.
Adoption of Accounting Standards and Updates	Adoption of Accounting Standards and Updates We are required to prepare our condensed 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 the six months ended January 31, 2022, we adopted: • FASB ASU No. 2019-12, which simplifies various aspects related to accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application. Our adoption of this ASU on August 1, 2021 did not have a material impact on our condensed consolidated financial statements or disclosures. • FASB ASU No. 2020-01, which clarifies the interactions between Topics 321, 323 and 815. This ASU clarifies that an entity should consider observable transactions that require it to either apply or discontinue the equity method of accounting for the purposes of applying the measurement alternative in accordance with Topic 321 immediately before applying or upon discontinuing the equity method. In addition, the amendments clarify the accounting for certain forward contracts and purchased options accounted for under Topic 815. Our adoption of this ASU on August 1, 2021 did not impact our condensed consolidated financial statements or disclosures. • FASB ASU No. 2020-06, which simplifies the accounting for convertible instruments by removing certain separation models (including the cash conversion model and the beneficial conversion feature model) for convertible instruments. As a result, for convertible instruments with conversion features that are not required to be accounted for as derivatives under Topic 815 or that do not result in substantial premiums accounted for as paid-in capital, the embedded conversion features are no longer separated from the host contract. Consequently, a convertible debt instrument will be accounted for as a single liability measured at its amortized cost, and convertible preferred stock will be accounted for as a single equity instrument measured at its historical cost as long as no other features require bifurcation and recognition as derivatives. On August 1, 2021, we early adopted this ASU. Our adoption of this ASU did not have any impact on our condensed consolidated financial statements or disclosures. • FASB ASU No. 2021-08, which requires that an acquirer recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606, as if it had originated the contracts. Prior to this ASU, an acquirer generally recognized contract assets and contract liabilities assumed that arose from contracts with customers at fair value on the acquisition date. On August 1, 2021, we early adopted this ASU. Our early adoption of this ASU did not have any impact on our condensed consolidated financial statements or disclosures.
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). 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 Government Solutions segment and, to a lesser extent, certain location-based and messaging infrastructure contracts in our public safety and location technologies product line within our Commercial Solutions segment. For service-based contracts in our public safety and location technologies product line, 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 modems, solid-state and traveling wave tube amplifiers) and certain contracts for our solid-state, high-power RF 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 Condensed Consolidated Balance Sheet. 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 six months ended January 31, 2022 and 2021, respectively. 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 contract liability balance at July 31, 2021 and July 31, 2020, $35,517,000 and $24,320,000 was recognized as revenue during the six months ended January 31, 2022 and 2021, 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. Incremental costs to obtain or fulfill contracts with an amortization period greater than one year were not material. As commissions payable to our internal sales and marketing employees or contractors are contingent upon multiple factors, such commissions are not considered direct costs to obtain or fulfill a contract with a customer and are expensed as incurred in selling, general and administrative expenses on our Condensed Consolidated Statements of Operations. As for commissions payable to our third-party sales representatives related to long-term contracts, we do consider these types of commissions both direct and incremental costs to obtain and fulfill such contracts. Therefore, such types of commissions are included in total estimated costs at completion for such contracts and expensed over time through cost of sales on our Condensed Consolidated Statements of Operations.
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 and accrued expenses) approximate their fair values due to their short-term maturities. The fair value of our Credit Facility that we entered into on October 31, 2018 approximates its carrying amount due to its variable interest rate and pricing grid that is dependent upon our leverage ratio as of the end of each fiscal quarter. The stock purchase agreement for the acquisition of UHP provides for a contingent earn-out payment of up to $9,000,000, if specified sales milestones are reached during a defined period ending September 30, 2022. The earn-out is accounted for as a contingent consideration liability to be recorded at its fair value. See Note (2) - " Acquisitions " for more information regarding the estimated fair value of the earn-out. As of January 31, 2022 and July 31, 2021, other than the financial instruments discussed above, we had no other significant assets or liabilities included in our Condensed Consolidated Balance Sheets recorded at fair value, as such term is defined by FASB ASC 820.
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, settlement of escrow and earn-out arrangements related to our acquisition of UHP and the assumed conversion of Convertible Preferred Stock, if dilutive, outstanding during each respective period.

Accounting Changes and Error Corrections [Abstract]
Adoption of Accounting Standards and Updates	Adoption of Accounting Standards and Updates We are required to prepare our condensed 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 the six months ended January 31, 2022, we adopted: • FASB ASU No. 2019-12, which simplifies various aspects related to accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application. Our adoption of this ASU on August 1, 2021 did not have a material impact on our condensed consolidated financial statements or disclosures. • FASB ASU No. 2020-01, which clarifies the interactions between Topics 321, 323 and 815. This ASU clarifies that an entity should consider observable transactions that require it to either apply or discontinue the equity method of accounting for the purposes of applying the measurement alternative in accordance with Topic 321 immediately before applying or upon discontinuing the equity method. In addition, the amendments clarify the accounting for certain forward contracts and purchased options accounted for under Topic 815. Our adoption of this ASU on August 1, 2021 did not impact our condensed consolidated financial statements or disclosures. • FASB ASU No. 2020-06, which simplifies the accounting for convertible instruments by removing certain separation models (including the cash conversion model and the beneficial conversion feature model) for convertible instruments. As a result, for convertible instruments with conversion features that are not required to be accounted for as derivatives under Topic 815 or that do not result in substantial premiums accounted for as paid-in capital, the embedded conversion features are no longer separated from the host contract. Consequently, a convertible debt instrument will be accounted for as a single liability measured at its amortized cost, and convertible preferred stock will be accounted for as a single equity instrument measured at its historical cost as long as no other features require bifurcation and recognition as derivatives. On August 1, 2021, we early adopted this ASU. Our adoption of this ASU did not have any impact on our condensed consolidated financial statements or disclosures. • FASB ASU No. 2021-08, which requires that an acquirer recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606, as if it had originated the contracts. Prior to this ASU, an acquirer generally recognized contract assets and contract liabilities assumed that arose from contracts with customers at fair value on the acquisition date. On August 1, 2021, we early adopted this ASU. Our early adoption of this ASU did not have any impact on our condensed consolidated financial statements or disclosures.
