    Executive summary

    TransDigm Q3 FY25 — Strong Aftermarket and Defense Growth Offset by OEM Headwinds

    TransDigm reported a mixed quarter, with robust performance in its commercial aftermarket and defense segments driving strong EBITDA margins and cash flow. However, commercial OEM revenues faced headwinds from lower-than-expected production rates and inventory destocking at major airframe manufacturers. The company updated its full-year sales guidance downward while raising its EBITDA outlook, reflecting these market dynamics and recent acquisitions. Leadership changes were announced, with Mike Lisman set to take over as CEO.

    Why it matters

    Indicates recovery from destocking and OEM production challenges, crucial for overall revenue trajectory.

    You can see that in the guidance for today, which implies in commercial OEM that Q4 returns to positive growth.

    Q&A highlights

    5

    Why has TransDigm's aftermarket growth trailed peers over the last 1.5 years, and will it return to industry average growth rates?

    Management stated their aftermarket growth is not significantly different from expectations, moderating as the COVID recovery completed. They noted less engine exposure compared to some peers, where engine content saw very strong growth. They expect continued growth but cannot forecast comparison to peers with precision.

    “We weighed a bit less toward engine than some of our peers. Engine for us was very strong this quarter as well into the double digits on a percentage basis.”

    Detailed Narrative

    01

    Leadership Transition and Succession Planning

    Kevin Stein announced his upcoming retirement as CEO on September 30, 2025, with Mike Lisman, current Co-COO, stepping into the CEO role. The company also announced internal promotions, including Patrick Murphy as the new Co-COO and Dave Wilmot as Executive Vice President, both effective immediately. Armani Vadiee was promoted to General Counsel and Chief Compliance Officer, highlighting TransDigm's focus on internal leadership development and succession planning.

    02

    M&A Strategy and Capital Allocation Priorities

    TransDigm continues its disciplined M&A strategy, focusing on small to mid-sized proprietary aerospace businesses that fit its model and offer clear paths to private equity-like returns (20% IRR). The company recently closed the acquisition of Servotronics for $138 million and agreed to acquire Simmonds Precision from RTX for $765 million. Capital allocation priorities remain reinvestment in businesses, accretive M&A, and returning capital to shareholders via buybacks or dividends, with debt paydown being a less likely fourth option currently.

    03

    Commercial OEM Headwinds and Inventory Destocking

    Commercial OEM revenue was down 7% in Q3 FY25, primarily due to lower-than-expected production rates at Boeing (impacted by strike) and Airbus (ramp challenges). This led to customers realigning backlog and destocking inventory, particularly impacting Q3 shipments. While the impact is expected to be temporary, with Q4 returning to positive growth, the recovery is anticipated to be 'bumpy and uneven' on a quarterly sales basis as OEMs rightsize inventory levels.

    04

    Commercial Aftermarket Performance and Submarket Dynamics

    Commercial aftermarket revenue grew 6% in Q3 FY25, with varied performance across submarkets. Freight and interiors segments showed stronger growth (double digits and well into double digits, respectively), while passenger and biz jet submarkets performed slightly below the overall rate. Operating units with higher engine content posted very solid growth (double digits). Distributor point-of-sale trends also outpaced overall aftermarket growth, indicating continued demand.

    05

    Supply Chain and Production Environment

    The supply chain continues to improve, though it has not fully returned to pre-pandemic efficiency. Common bottlenecks persist in castings and certain electronic components. Despite these challenges, TransDigm's operating units are well-positioned to support higher production rates as OEMs work to increase aircraft output to meet high demand and long backlogs. The company remains encouraged by recent progress on the 737 MAX production line.

    06

    Debt Management and Liquidity

    TransDigm ended Q3 FY25 with a net debt-to-EBITDA ratio of 4.9x, down from 5.1x last quarter, and a cash balance of nearly $2.8 billion. The company refinanced $2.7 billion of senior subordinated notes, extending their maturity to 2033 and pushing out the nearest term maturity to August 2028. Approximately 75% of the $25 billion gross debt balance is hedged through FY27, providing stability against interest rate fluctuations. The company maintains flexibility for future capital deployment.
