    Executive summary

    TransDigm Group Q4 FY25 — Strong Aftermarket and Defense Growth Drive Solid Performance

    TransDigm concluded fiscal 2025 with robust performance, driven by strong commercial aftermarket and defense growth, exceeding its own guidance. The company remains committed to its value-based operating methodology and disciplined capital allocation, including significant M&A and shareholder returns. While facing some near-term margin dilution from recent acquisitions and mix shifts, management anticipates continued underlying margin improvement and is well-positioned for fiscal 2026 amidst a recovering aerospace market.

    Highlights

    5

    • Q4 FY25 revenue and EBITDA as defined margins surpassed most recently published guidance.

    • Commercial aftermarket revenue increased by approximately 11% in Q4 and 10% for the full year FY25.

    • Defense market revenue grew by approximately 16% in Q4 and 13% for full year FY25.

    • Strong operating cash flow generation of over $500 million in Q4 FY25, with $2.4 billion for the full year.

    • Allocated approximately $7 billion of capital in FY25 across M&A, a $90 per share special dividend, and $600 million in share repurchases.

    Concerns

    4

    • Fiscal 2026 EBITDA guidance midpoint of $5.15 billion implies an expected margin of around 52.3%, including 200 basis points of margin dilution from recent acquisitions.

    • Fiscal 2026 EBITDA guidance includes a 0.5 to 1.0 percentage point headwind from commercial OE and defense mix.

    • Commercial OEM revenue performance for full year FY25 was softer than originally expected, primarily due to the Boeing strike and Airbus production ramp-up challenges.

    • Q1 FY26 revenues, EBITDA, and EBITDA margins are anticipated to be lower than other quarters due to approximately 10% fewer working days.

    Risks & headwinds

    5
    OEM Production Ramp-up ChallengesFY26

    bumpy and uneven on a quarterly basis

    Mitigation: Commercial OEM revenue guidance range of high single-digit to mid-teens percentage growth contemplates reasonable risks around the Boeing and Airbus rates.

    Margin Dilution from Recent AcquisitionsFY26

    additional 200 basis points of margin dilution

    Mitigation: Management expects to march the margins upward in the fullness of time, as these are great products with nothing fundamentally different from past successful acquisitions.

    Commercial OE and Defense Mix HeadwindFY26

    0.5 percentage point to a full percentage point

    Mitigation: Adjusting for this and acquisition dilution, margins would have increased more in line with typical base business improvement.

    Fewer Working Days in Q1 FY26Q1 FY26

    about 10% or so fewer working days

    Mitigation: Anticipated and factored into guidance, with Q1 revenues, EBITDA, and EBITDA margins expected to be lower than other quarters of FY26.

    Defense Sales LumpinessOngoing

    difficult to forecast with accuracy and precision, especially on a quarterly basis

    Mitigation: Management is hopeful they are being conservative on defense guidance for FY26.

    What to watch in Q1 FY26

    Simmonds and Servotronics Integration Progress

    next quarter
    Currentstill early, but experience to date indicates these are going to be two very good additions
    Targetfurther progress in margin ramp-up and operational integration

    Why it matters

    Successful integration and margin expansion of recent acquisitions are key to offsetting dilution and driving overall profitability.

    It's still early, but our experience to date indicates that these are going to be two very good additions to TransDigm.

    Q&A highlights

    6

    Will TransDigm expand its M&A aperture beyond traditional A&D, similar to past ventures into test and measurement, under the new CEO's tenure?

    While past ventures like Calspan and Raptor have been positive, the current M&A focus remains primarily on traditional aerospace and defense components. Future branching out is possible but not the immediate focus.

    “As we sit here today, the focus is more of where it's always been.”

    Detailed Narrative

    01

    Consistent Strategy and Value Creation

    TransDigm emphasizes its unique strategy focused on proprietary aerospace products, significant aftermarket content, a value-based operating methodology, and a decentralized structure. This approach aims to deliver private equity-like returns with public market liquidity, consistently allocating capital to reinvestment, accretive M&A, and shareholder returns. The company's long-standing goal is to create intrinsic shareholder value through all phases of the aerospace cycle.

    02

    Capital Allocation and Liquidity

    The company allocated approximately $7 billion in FY25, including the acquisitions of Servotronics and Simmonds Precision, $300 million in tuck-in acquisitions, a $90 per share special dividend, and $600 million in share repurchases. Despite these actions, TransDigm ended FY25 with a $2.8 billion cash balance ($2 billion pro forma for Simmonds) and significant liquidity, maintaining flexibility for future M&A or shareholder returns. The net debt-to-EBITDA ratio was 5.8x at year-end, within the comfortable 5% to 7% target range.

    03

    Commercial Market Dynamics

    Commercial OEM revenues returned to growth in Q4 FY25 after a brief destocking period, though full-year performance was softer due to Boeing strike and Airbus ramp-up issues. Commercial aftermarket revenues saw robust growth, up 11% in Q4 and 10% for the full year, with all submarkets contributing positively. Management expects continued, albeit bumpy, recovery in OEM build rates, with commercial transport bookings up over 20% in Q4.

    04

    Defense Market Strength and New Business

    Defense revenue grew strongly, up 16% in Q4 and 13% for the full year, driven by new business wins and team performance in both domestic and international markets. The company secured content on the F-47 program and announced significant awards for Airborne Systems' glide modulation canopy ($5 million initial order) and IrvinGQ's PRIBAD system ($30 million contract), alongside a sensor suite agreement with Rolls-Royce for the Trent XWB-84 engine.

    05

    Operational Efficiency and Automation

    TransDigm plans approximately $300 million in capital expenditures for FY26, with two-thirds dedicated to new business and productivity projects, including over 150 new automation initiatives. These efforts are expected to keep headcount roughly flat despite increased commercial and defense OEM work content, driving higher sales per employee and improving yields. The cost of automation technology continues to decrease year-over-year.

    06

    Acquisition Integration and Margin Outlook

    The recently acquired Simmonds Precision Products and Servotronics are integrating well, with experienced teams leading the process. While these acquisitions initially bring a 200 basis point margin dilution and a 0.5 to 1.0 percentage point headwind from mix shift in FY26, management expects underlying margin improvement in the base business to continue, with margins anticipated to expand over time⏳ for the acquired entities as they are integrated into TransDigm's operating methodology.
