Legal Proceedings and Other Matters	Legal Proceedings and Other Matters Former CEO Related Matters On March 12, 2024, the Company terminated Ken Peterman, its President and CEO at the time, for Cause pursuant to the terms of his employment agreement dated September 12, 2022 (the “Employment Agreement”). On November 21, 2024 (as amended on December 31, 2024), Mr. Peterman filed a claim with the American Arbitration Association, alleging that Comtech materially breached the Employment Agreement in the termination for Cause and that the termination was a retaliation for whistleblowing by Mr. Peterman in connection with certain of the Company’s prior financial and accounting practices. The Company independently investigated, with the assistance of an outside advisor, Mr. Peterman's allegations that he was a whistleblower and determined that such allegations were not substantiated. Mr. Peterman claims he is owed direct contractual damages in an amount in excess of $6,000,000 and consequential damages for injury to his professional reputation in excess of $35,000,000. The Company believes Mr. Peterman's claims are entirely without merit and will defend itself vigorously in the matter. On December 11, 2024, Mr. Peterman was indicted by the United States Attorney for the Eastern District of New York and arrested on charges of insider trading and securities fraud. He was also charged with similar allegations by the SEC in a civil lawsuit filed in the Eastern District of New York the same day. The Company is not named as a defendant in either proceeding. CGC Divestiture Export Matters As discussed further in Note (2) – Divestitures, during our fourth quarter of fiscal 2024, we ceased operations of our steerable antenna product line in Basingstoke, United Kingdom, which incurred cumulative operating losses since our acquisition of this business in fiscal 2020. In November 2024, as part of the wind down of such operations, we completed a disclosure to His Majesty’s Revenue and Customs agency in the United Kingdom (“HMRC”) related to potential violations of export compliance laws in the United Kingdom. Such disclosure was precipitated by the United Kingdom customs agency’s halting, in March 2024, an antenna shipment destined for end use by a customer in Azerbaijan and for which we did not have an appropriate export license at the time. Due to our commitment to comply with global export regulations, we immediately and voluntarily initiated a historical review of exports from our Basingstoke location since our acquisition of such business in fiscal 2020. Based on such review, we voluntarily disclosed to the HMRC a misclassification of specially designed, configured or modified antenna systems for military end users and build-to-print aircraft parts. Based on HMRC guidelines and with the assistance of outside local counsel, we estimated that monetary fines and penalties related to potential violations as outlined in our disclosure could range from zero to approximately $9,000,000, with no single amount within that range being a best estimate. Through the issuance date, based on such review and disclosure to HMRC, we determined that a financial loss related to this matter is more than remote, but less than probable given the multiple factors that could influence the ultimate outcome, including but not limited to: the voluntary nature of our disclosure; our Basingstoke operation’s historical compliance record; the number of exports involved; and the nature of the potential violation(s). Based on such determination, we have not accrued for any contingent loss related to these matters as of October 31, 2024. Other Matters In the ordinary course of business, we include indemnification provisions in certain of our customer contracts to indemnify, hold harmless and reimburse such customers for certain losses, including but not limited to losses related to third-party claims of intellectual property infringement arising from the customer’s use of our products or services. We may also, from time to time, receive indemnification requests from customers related to third-party claims that 911 calls were improperly routed during an emergency. We evaluate such claims as and when they arise. We do not always agree with customers that they are entitled to indemnification and in such cases reject their claims. Despite maintaining that we have properly carried out our duties, we may seek coverage under our various insurance policies; however, we cannot be sure that we will be able to maintain or obtain insurance coverage at acceptable costs or in sufficient amounts or that our insurer will not disclaim coverage as to such claims. Accordingly, pending or future claims asserted against us by a party that we are obligated to indemnify could result in legal costs and damages that could have a material adverse effect on our consolidated results of operations and financial condition. There are also certain other pending and threatened legal actions which arise in the normal course of business. Although the ultimate outcome of these matters is difficult to accurately predict, we believe that the outcome of these other matters will not have a material adverse effect on our consolidated financial condition or results of operations. Employment, Change of Control and Indemnification Agreements We have entered into employment and/or change of control agreements, as well as indemnification agreements with certain of our executive officers and certain key employees. All of these agreements may require payments by us, in certain circumstances, including, but not limited to, a change in control of the Company or termination of the employee.
