What Does TransDigm Offer That Huntington Ingalls Does Not

Investors can gain exposure to defense spending through either Huntington Ingalls Industries (HII) or TransDigm (TDG), and both companies cited supportive defense budgets on their latest earnings calls. Huntington Ingalls constructs aircraft carriers, submarines and amphibious assault ships for the U.S. Navy. TransDigm supplies highly engineered aircraft components to military buyers, plane makers and the aftermarket. Both companies raised 2026 forecasts this summer, so what exactly did each one raise?

What Did Each Company Raise This Summer?

On July 30, 2026, Huntington Ingalls raised only its shipbuilding forecasts. The company increased its 2026 shipbuilding revenue guidance to a midpoint of $10.3 billion from $9.8 billion, citing plans to deliver five ships. Forecasts for free cash flow and the Mission Technologies division remained unchanged.

TransDigm issued a company-wide upgrade on August 4, 2026. The aerospace supplier pushed its fiscal 2026 sales forecast to a midpoint of $10.5 billion from $10.4 billion, while lifting its net income projection to $2.13 billion at the midpoint from $2.07 billion.

Executives boosted growth expectations for commercial aircraft parts across both the aftermarket and new planes, linking stronger sales in the latter to increased aircraft production at Boeing and Airbus. In the defense segment, TransDigm anticipates growth in the high-single-digit to low-double-digit range. So the two raises are different kinds of news: Huntington Ingalls expects more Navy ships to move through its yards, whereas TransDigm's raise rests on demand for commercial aircraft alongside defense.

What Could Go Wrong For Each Company?

Delayed cash payments pose a risk for Huntington Ingalls. The shipbuilder posted a negative $614 million in free cash flow during the first half of 2026, yet continues to project $500 million to $600 million for the full year. Hitting that target requires a large inflow of free cash flow in the fourth quarter, according to management. Executives attributed the second-quarter shortfall against the company's own forecast to the timing of receipts and disbursements.

TransDigm faces risk from debt it takes on by choice. The company holds total debt equal to 51.6% of its market value, compared with 26.4% at Huntington Ingalls. By the end of its fiscal third quarter, TransDigm reported net debt slightly above 5.8 times EBITDA, its measure of earnings before interest, taxes, depreciation and amortization. Management targets staying between 5 and 7 times, noting this range preserves capacity for further acquisitions. Approximately 75% of TransDigm's debt remains fixed through fiscal 2029, providing what executives described as a cushion against near-term interest-rate moves.

Where Each Company Comes Out Ahead

TransDigm wins on margin and growth. Over the four quarters ended June 27, 2026, the aerospace supplier kept 46.5% of its sales as operating profit, compared with 4.9% for Huntington Ingalls over its four quarters to June 30. TransDigm also delivered faster revenue growth across each of the last three twelve-month periods, averaging a 17.1% annual expansion against 6.8% for Huntington Ingalls. That gap narrowed in the most recent twelve months, with TransDigm growing at 16.6% and Huntington Ingalls reaching 14.0%.

Huntington Ingalls wins on price and on debt. At the October 27, 2026 close, the shipbuilder traded at 16.8 times earnings, against 30.5 times for TransDigm.

So TransDigm comes out ahead on margin and growth, and Huntington Ingalls on price and borrowing. For Huntington Ingalls, free cash flow, negative in the first half of 2026, remains the number to watch against its full-year forecast. The company is expected to report its third quarter on October 29, 2026.
