TransDigm's commercial aftermarket — the highest-margin, most defensible part of the business — grew 30.1% year over year in the quarter ended June 27, 2026, and total sales rose 22.5% to $2,741 million. Yet net income attributable to TD Group advanced only 9.5% to $539 million, because net interest expense climbed 29.5% to $514 million and now consumes 41.9% of operating income. That gap between the top line and the bottom line is the whole story of this filing: the operating business is performing, and the capital structure is taking an increasing share of the result. For a company carrying $33.5 billion of financial debt against a $9.8 billion stockholders' deficit, the question is no longer whether aftermarket demand is strong — it plainly is — but whether it is compounding faster than the cost of the balance sheet that funds it.
This report covers TransDigm's fiscal third quarter of 2026, the thirteen weeks ended June 27, 2026 (calendar Q2 2026). TransDigm's fiscal year ends September 30.
1. Condensed Consolidated Balance Sheet
1-1. Principal asset lines
| Item | Sept 30, 2025 ($M) | June 27, 2026 ($M) | Change % |
|---|---|---|---|
| Cash and cash equivalents | 2,808 | 2,773 | −1.2 |
| Trade accounts receivable—net | 1,617 | 1,817 | +12.4 |
| Inventories—net | 2,095 | 2,586 | +23.4 |
| Property, plant and equipment—net | 1,579 | 1,740 | +10.2 |
| Goodwill | 10,612 | 12,166 | +14.6 |
| Other intangible assets—net | 3,454 | 4,724 | +36.8 |
| Total assets | 22,909 | 26,754 | +16.8 |
The $3,845 million increase in total assets is almost entirely an acquisition artifact. Goodwill rose $1,554 million and other intangibles $1,270 million, together accounting for 73% of the asset growth. Goodwill and intangibles now represent 63.1% of the balance sheet, up from 61.4%, which is the structural signature of a serial acquirer that buys proprietary aerospace franchises rather than factories.
The working capital build deserves a closer look, because the headline percentages overstate the organic pressure. Inventories rose $491 million on the balance sheet, but the cash flow statement shows only $232 million of organic inventory build net of acquisitions — meaning roughly $259 million arrived on the books through purchase accounting. The same reconciliation applies to receivables: a $200 million balance-sheet increase against a $126 million organic change, leaving about $74 million acquired. Adjusted for that, organic inventory growth is broadly proportionate to organic sales growth rather than a sign of channel congestion.
Inventories are stated using average cost and FIFO, not LIFO, so no LIFO reserve distorts comparison with IFRS-reporting European component peers. Finance lease obligations of $313 million sit inside long-term debt under ASC 842. Note also that R&D is expensed as incurred under US GAAP, which understates TransDigm's reported operating margin relative to IFRS peers that capitalize development costs.
1-2. Debt structure: financial versus operating liabilities
Financial debt totals $33,485 million net of issuance costs — $139 million current portion, $725 million drawn on the trade receivable securitization facility, and $32,621 million long-term. Against $2,773 million of cash, net debt is $30,712 million. On the third quarter's annualized EBITDA As Defined run rate of $5,788 million, that is roughly 5.3 times net leverage.
Operating liabilities are trivial by comparison: accounts payable of $434 million (+17.9%) and other non-current liabilities of $549 million. Accrued and other current liabilities rose 32.1% to $1,276 million, but this is substantially accrued interest rather than trade obligations — the cash flow statement shows accrued interest increasing $208 million over nine months.
The maturity profile is the reassuring part. The earliest note maturity is the 6.750% secured notes due 2028 ($2,100 million); nothing in the bond stack matures before then, and coupons on the fixed-rate tranches range from 4.625% to 7.125%. The variable exposure is the $12,868 million term loan book, of which the new Tranche N loans ($1,800 million total, maturing February 2033) price at Term SOFR plus 2.50%. Interest rate swap and collar agreements entered in the fourth quarter of fiscal 2025 hedge a portion of that floating exposure, and the securitization facility was drawn at 5.03%. Cash paid for interest over nine months was $1,210 million, up 33.3% from $908 million.
1-3. Capital structure
TD Group stockholders' deficit widened to $(9,809) million from $(9,686) million. The mechanics are worth spelling out because they are unusual. Accumulated deficit actually improved by $1,499 million, from $(10,606) million to $(9,107) million, as retained earnings absorbed the $1,519 million of profit — there was no special dividend this year, against $4,396 million of dividends and dividend equivalents paid in the comparable prior period. Additional paid-in capital rose $242 million on stock compensation and option exercises.
What deepened the deficit was treasury stock, which grew from $(2,206) million to $(4,026) million — a $1,820 million increase. In other words, TransDigm earned $1,519 million and returned more than that through buybacks alone. Accumulated other comprehensive loss widened to $(54) million from $(10) million, driven by a $77 million foreign currency translation loss partly offset by $33 million of unrealized derivative gains. A new line, redeemable noncontrolling interests of $81 million, appears outside permanent equity: it reflects put and call options held by JPE and VSA management on their retained 5% and 4% stakes, exercisable through fiscal 2033 at a formula price based on an EBITDA multiple.
2. Condensed Consolidated Statements of Income
2-1. Multi-year revenue and profit trajectory
| Item | FY2023 ($M) | FY2024 ($M) | FY2025 ($M) | FY2026 9M ($M) |
|---|---|---|---|---|
| Net sales | 6,585 | 7,940 | 8,831 | 7,569 |
| Operating income | 2,923 | 3,531 | 4,165 | 3,447 |
| Operating margin (%) | 44.4 | 44.5 | 47.2 | 45.5 |
| Net income | 1,298 | 1,714 | 2,074 | 1,521 |
| Net margin (%) | 19.7 | 21.6 | 23.5 | 20.1 |
Revenue compounded at 15.8% annually from FY2023 to FY2025. Commercial aerospace is in a multi-year recovery rather than at a cyclical extreme, and aftermarket consumption on an installed base with a 25-to-30-year life gives TransDigm far better visibility than a typical cyclical industrial. But the FY2026 nine-month margins mark a break in the trend: operating margin of 45.5% is 170 basis points below FY2025's 47.2%, and net margin of 20.1% is 340 basis points below.
2-2. Third quarter in detail
| Item | Q3 FY2025 ($M) | Q3 FY2026 ($M) | Change % |
|---|---|---|---|
| Net sales | 2,237 | 2,741 | +22.5 |
| Gross profit | 1,332 | 1,628 | +22.2 |
| Gross margin (%) | 59.5 | 59.4 | — |
| Selling and administrative | 242 | 332 | +37.2 |
| Amortization of intangibles | 51 | 69 | +35.3 |
| Income from operations | 1,039 | 1,227 | +18.1 |
| Operating margin (%) | 46.4 | 44.8 | — |
| Interest expense—net | 397 | 514 | +29.5 |
| Net income attributable to TD Group | 492 | 539 | +9.5 |
| Earnings per share ($) | 8.47 | 9.39 | +10.9 |
Gross margin held essentially flat at 59.4% — the pricing power on proprietary sole-source parts is intact. The compression happened below the gross line. A 22.5% sales increase produced only an 18.1% rise in operating income, implying operating leverage of 0.80 times: TransDigm grew profit slower than revenue, which is the inverse of what this business normally delivers.
Two costs explain it. Selling and administrative expenses rose 37.2%, and intangible amortization rose 35.3% as the new asset base began amortizing. Stripping out the $35 million of acquisition transaction and integration-related expenses (versus $9 million a year earlier) gives a normalized operating income of $1,262 million, a 46.0% margin — still 81 basis points below the prior year's comparable 46.9%. So the dilution is not purely one-time deal noise.
Below operating income, the leverage effect takes over. Interest coverage fell to 2.39 times from 2.62 times. The effective tax rate rose to 24.3% from 22.4%, and management attributes part of the year-to-date increase to a valuation allowance on the net interest deduction limitation — a concrete sign that the debt load has grown large enough that a portion of the interest is no longer currently deductible. EPS grew 10.9% versus net income growth of 9.5%; the 1.2% reduction in weighted-average shares to 57.4 million contributed roughly $0.11 of the $0.92 improvement.
2-3. Where the growth came from
| Revenue channel (Q3) | FY2025 ($M) | FY2026 ($M) | Change % | % of sales |
|---|---|---|---|---|
| Commercial & non-aerospace aftermarket | 698 | 908 | +30.1 | 33.1 |
| Defense | 963 | 1,148 | +19.2 | 41.9 |
| Commercial & non-aerospace OEM | 536 | 639 | +19.2 | 23.3 |
| Non-aviation | 40 | 46 | +15.0 | 1.7 |
Aftermarket outgrew every other channel and lifted its share of sales to 33.1% from 31.2%. That mix shift should have been margin-accretive, which makes the reported compression more notable — it means the offsetting drag from newly acquired, not-yet-optimized businesses was larger than the mix benefit.
The segment data confirms where the drag sits. Power & Control, which absorbed every acquisition of the past year, grew sales 32.5% to $1,509 million but saw its EBITDA As Defined margin fall to 53.6% from 56.7%, a 317 basis point decline. Airframe, essentially organic, grew a more modest 12.1% to $1,186 million while expanding its margin to 54.4% from 53.8%. The organic business is still improving; the acquired business is running below TransDigm's standard and awaiting the company's usual multi-year margin conversion.
Consolidated EBITDA As Defined — a non-GAAP measure that excludes depreciation and amortization, non-cash stock and deferred compensation, foreign currency effects, acquisition transaction and integration costs, inventory step-up amortization, and refinancing costs — was $1,447 million, up 18.9%, at a 52.8% margin versus 54.4%.
3. Condensed Consolidated Statements of Cash Flows
| Item (39 weeks) | FY2025 ($M) | FY2026 ($M) | Change |
|---|---|---|---|
| Net cash from operating activities | 1,531 | 1,691 | +10.5% |
| Net cash used in investing activities | (349) | (3,370) | — |
| Net cash from (used in) financing activities | (4,669) | 1,652 | — |
| Cash at end of period | 2,792 | 2,773 | −0.7% |
Free cash flow, defined as operating cash flow less the $205 million of capital expenditures, was $1,486 million against $1,375 million a year earlier — up 8.1%, but with the FCF margin slipping to 19.6% from 21.5%. Capital intensity remains very light at 2.7% of sales, and this is maintenance spending on an asset-light franchise, not a growth cycle; TransDigm buys growth rather than building it.
Earnings quality is sound: operating cash flow covered net income 1.11 times, improved from 1.05 times. One caveat belongs here — the $208 million build in accrued interest is a genuine source of operating cash but reflects the gap between $1,472 million of interest expense and $1,210 million of interest actually paid on semiannual coupon schedules. Excluding that build, underlying operating cash flow is closer to $1,483 million.
The financing swing is the most consequential line in the statement. Last year's $(4,669) million outflow was dominated by $4,396 million of dividends and dividend equivalents — the special dividend. This year, financing turned to a $1,652 million inflow, funded by $1,686 million of new senior subordinated notes and $1,781 million of new term loans. Nine months of capital deployment totalled $4,966 million: $3,159 million on acquisitions and $1,807 million on buybacks, against $1,486 million of free cash flow. The $3.5 billion difference came from the debt markets.
4. What Else Matters in This Filing
The acquisition program ran at record scale. Three transactions define the year: Simmonds Precision Products, bought from Goodrich on October 6, 2025 for approximately $757 million in fuel and proximity sensing; JPE and VSA, closed April 7, 2026 for approximately $2.2 billion, a pure-play commercial aftermarket PMA platform where nearly all sales are aftermarket; and $257 million of bolt-ons. All landed in Power & Control. The JPE/VSA purchase generated $1,134 million of goodwill and $953 million of intangibles, of which $1,085 million and $898 million respectively are tax-deductible over fifteen years — a meaningful cash tax shield that partially offsets the interest deduction limitation.
The Stellant withdrawal left $1.5 billion of unspent debt on the books. TransDigm signed to buy Stellant Systems for approximately $960 million on December 30, 2025, then announced on July 13, 2026 that it had withdrawn. The filing is explicit that the April 17, 2026 issuance — $500 million of 6.125% 2034 notes plus $1,000 million of additional Tranche N term loans, raised specifically to fund Stellant — carried no special mandatory redemption and remains outstanding. The company borrowed for a deal it did not do and kept the proceeds.
That capital was redeployed within two weeks. On July 27, 2026, TransDigm announced a definitive agreement to acquire Prince & Izant for approximately $1.1 billion in cash, subject to US regulatory approvals and customary closing conditions. Separately, on July 10 the securitization facility was upsized from $725 million to $1,000 million with maturity extended to July 9, 2027, and $25 million was drawn in July. Liquidity was being rebuilt, not paid down.
Buyback capacity is large and freshly authorized. The Board added $5.0 billion to the repurchase program in November 2025. During the third quarter alone the company repurchased 809,101 shares at an average of $1,208.20 for $978 million, bringing the nine-month total to 1,496,383 shares at $1,207.50 for $1,807 million. As of June 27, 2026, $3,981 million remained available.
Defense concentration cuts both ways. Defense is 41.9% of quarterly sales at $1,148 million, growing 19.2%. That is a stabilizer against commercial air traffic softness, but it also ties a large share of revenue to US and allied government budget cycles and to the procurement scrutiny that has periodically focused on TransDigm's pricing on sole-source defense parts.
Tax exposures are open but not quantified as material. The company is under federal examination in Canada (fiscal 2018–2019), France (fiscal 2020–2022) and Germany (fiscal 2017–2024), and is subject to US state examinations from fiscal 2015. Unrecognized tax benefits at June 27, 2026 were disclosed as not material. Provisions of the One Big Beautiful Bill Act, enacted July 4, 2025, are expected to affect the company mainly from fiscal 2027; the impact this quarter was not material. No litigation contingencies are quantified in the portions of the filing reviewed.
5. Key Implications and Outlook
What grew. The commercial aftermarket, decisively — up 30.1% in the quarter and now a third of revenue, with gross margin holding at 59.4%. Airframe demonstrated that the underlying operating model still works, adding 60 basis points of EBITDA margin on 12.1% organic growth. Free cash flow reached $1,486 million over nine months on capital expenditure of just 2.7% of sales.
What is at risk. The cost of the capital structure is rising faster than the earnings it funds. Interest expense grew 29.5% against 22.5% sales growth; coverage thinned to 2.39 times from 2.62 times; the effective tax rate is climbing partly because interest deductibility is now constrained. Net leverage of roughly 5.3 times on annualized third-quarter EBITDA is manageable while the aftermarket runs hot, and the maturity wall is genuinely distant with nothing due before 2028 — but the model depends on aftermarket volumes that ultimately track global air traffic. Operating leverage of 0.80 times this quarter is the number to watch: if acquired margins do not converge upward on TransDigm's historical pattern, the dilution stops being transitional. Goodwill and intangibles at 63.1% of assets mean any sustained downturn in aftermarket demand would put impairment testing under real pressure.
Capital allocation. The priority order revealed by this filing is unambiguous: acquisitions first ($3,159 million), buybacks second ($1,807 million), debt reduction nowhere ($56 million of term loan repayment against $3,467 million of new issuance), and ordinary dividends absent. Management raised $1.5 billion for a deal it abandoned, declined to redeem the notes, and committed $1.1 billion to a different target fourteen days later — with $3,981 million of buyback authorization still unused. The historical pattern suggests that when the M&A pipeline cannot absorb the balance sheet capacity, the excess returns to shareholders as a large special dividend, as it did in fiscal 2025. Following the Prince & Izant close, the trade-off between another platform deal and a return-of-capital event is the decision that will most shape the fiscal 2027 balance sheet.
