TDG: Other company developments

Item 8.01. Other Events. On July 13, 2026, TransDigm Group Incorporated (the “Company”) announced that it has elected to withdraw from its proposed acquisition of Stellant Systems, Inc. (“Stellant”) from Arlington Capital Partners (“Seller”) and has notified relevant parties of its decision. The Company recently concluded, after careful consideration, that continuing to pursue the transaction through the regulatory review process was no longer in the best interests of the Company and its shareholders. In reaching this determination, the Company considered the uncertainty, the likely required time to complete the transaction relative to the contractual time limitation with Seller, and the opportunity cost of continuing to pursue the transaction rather than focusing on other strategic acquisition opportunities. Accordingly, the Company determined that withdrawing from the proposed acquisition represents the most prudent allocation of the Company's capital and management resources and is in the best interests of the Company and its shareholders. Following the Company's withdrawal of its regulatory filing on July 10, 2026, Seller provided the Company with notice of termination of the transaction agreement. The Company remains committed to its disciplined acquisition strategy and continues to evaluate acquisition opportunities that it believes will enhance long-term shareholder value.
