Honeywell Aerospace Q3 2026: net income +13%, but operating profit +1% only with $50M of tariff refunds

Overview

Q3 2026 (the quarter ended September 26, 2026) was Honeywell Aerospace's first full quarter as an independent company after its spin-off from Honeywell International on June 29. Sales rose 2.4% to $4,644 million, all of it organic (currency and acquisitions added nothing overall). Net income attributable to the company rose 12.7% to $726 million and diluted earnings per share (EPS) came in at $2.29, against $2.03 a year earlier. That profit jump overstates the business. The company's own measure of operating profit, adjusted EBIT (earnings before interest and tax, excluding spin-off costs and other items it treats as non-operating), rose just 0.9% to $1,161 million, and it includes about $50 million of one-time refunds of tariffs. Without them, operating profit was about 3% lower than a year ago.

Management still raised its full-year adjusted EPS guidance to $7.85–8.00 (from $7.60–7.90), raised the low end of its second-half free cash flow range and declared a first quarterly dividend of $0.40 a share. This analysis is written from the earnings release furnished with the October 28 Form 8-K (Exhibit 99.1). The full Q3 Form 10-Q, with management's discussion of each line item, was not yet on EDGAR when we wrote this.

Results

Source: Q3 2026 earnings release (Form 8-K, Exhibit 99.1). The EBIT margin is our calculation from the statement of operations, on the same basis as our Q2 report. "GAAP" means the official accounting figures. The year-ago EPS is a hypothetical figure: HONA had no shares before the spin, so the company divides 2025 profit by the 317 million shares it distributed. The release itself calls comparisons with pre-separation results "not considered meaningful." The year-ago figures are also carved out of Honeywell's books, with a share of head-office costs allocated to the business and no interest expense.

Takeaway: Reported profit rose 13% because last year's large environmental and spin-off charges did not come back. The operating business earned about the same on 2% more sales, and roughly $50 million of that came from one-time tariff refunds. Raising EPS guidance after a quarter like this is a bet on supply catching up with a $19.3 billion backlog in Q4 and 2027. Q3's 2% sales growth does not show that happening yet.

Where the $160 million rise in pre-tax income came from

Pre-tax income rose from $741 million to $901 million. Using the company's reconciliation of segment profit to pre-tax income:

The business itself contributed only $10 million of the increase. Everything else is either a large charge from last year that did not recur, or a new cost or income that comes with being a standalone company: interest on $15.85 billion of long-term debt, the fee for using the "Honeywell Aerospace" name, and income from the pension plans moved onto HONA's balance sheet (pension assets were $3,039 million at quarter end, against $13 million at December 31, 2025). Tax took a larger share than last year: the effective tax rate was 18.2% against 11.7%, so net income grew more slowly than pre-tax income (+12.7% against +21.6%).

Segment results

Segment margins are our calculation (segment profit ÷ segment sales).

Electronic Solutions (avionics, navigation, defense electronics) did best: commercial original-equipment and defense sales rose, and profit grew 11% as "tariff refunds and pricing more than offset unfavorable mix and higher costs." Much of the roughly $50 million tariff benefit likely landed here, so part of this segment's 1.7-point margin gain may not repeat. The release does not split the refunds by segment.

Engines & Power Systems is still the weak spot. Sales rose 3% on higher aftermarket volumes, but profit fell 16% as "unfavorable mix and higher costs more than offset price and the impact of tariff refunds." "Mix" here means selling more of the lower-margin products. Its margin of 16.5% is better than Q2's 12.4%, but still 3.7 points below last year.

Control Systems had flat sales: defense and space growth was cancelled out by lower commercial aftermarket sales. Profit rose 2% because price increases covered higher costs.

By end market, commercial original equipment (parts for newly built aircraft) grew 8% organically to $690 million as airliner build rates rose. Commercial aftermarket (spare parts and repairs for planes already flying) grew 2% to $2,126 million, held back by parts shortages. Defense and space grew 1% to $1,828 million: the CAES and Civitanavi businesses acquired earlier grew strongly, but international volumes fell "due to supply constraints" and a non-aerospace restricted government program is winding down.

What the headline numbers hide

• Most of the GAAP profit growth is a comparison effect. Last year's quarter carried $258 million of environmental expense and $143 million of transaction costs. This year those were $19 million and $18 million. The operating business (segment profit) grew $10 million.
• One-time tariff refunds prop up the "underlying" figure too. Adjusted EBIT includes an approximately $50 million net benefit from IEEPA tariff refunds. These refunds of duties already paid will not recur at this size. Excluding them, adjusted EBIT fell about 3.5% and the adjusted EBIT margin would be about 23.9% rather than 25.0%.
• Adjusted EPS is below GAAP EPS this time. The company's adjusted EPS of $2.21 removes $0.18 of pension income and adds back $0.06 of acquired-intangible amortization and $0.04 of transaction costs. Pension income comes from the investment assumptions on the pension plan, not from selling aerospace products, so the adjusted figure is the better read of the operations here. Note also that adjusted EPS does not exclude the $54 million trademark fee or the tariff refunds.
• Cash conversion was decent, but cash flow fell. Operating cash flow of $668 million was 91% of net income, and free cash flow (operating cash flow minus capital spending) was $500 million. Operating cash flow was still 20% lower than last year's $839 million, mainly because the company now pays interest. Inventories absorbed $158 million of cash in the quarter and are up 7.3% since December ($4,311M to $4,624M), faster than the 4.8% rise in nine-month sales. That fits a company stockpiling parts while it waits for scarce components. Receivables fell in the quarter, releasing $134 million. In the first half the company sold $344 million of receivables to banks, which pulls cash in sooner. The release does not say whether it did so again in Q3, so check the 10-Q.
• Capital returned: nothing yet. The cash flow statement shows no share repurchases and no dividends in Q3, despite the $3.5 billion buyback authorized on July 23. The first $0.40 dividend is payable December 4 (about $127 million at 317 million shares outstanding). The share count is not a factor in EPS this quarter: diluted weighted shares were 317.7 million, against the hypothetical 317 million used for 2025.
• Guidance moved up, but mainly on EPS. The full-year sales growth range is unchanged at 4–5% organic. The adjusted EBIT range was narrowed around the same $4.4 billion midpoint. The adjusted EPS range rose by $0.10–0.25. Pension income can't explain that, because adjusted EPS excludes it. With the EBIT midpoint unchanged, the rise has to come from below the operating line (interest, tax or other items), and the release does not say which. The 10-Q may show whether it lasts.

On balance the quarter is flattered: net income rose 12.7%, but the operating business's profit was flat, about 3% lower without the one-time tariff refunds, and the GAAP growth came almost entirely from last year's environmental and spin-off charges not recurring.

Did last time's read hold up?

Our Q2 report named three things to watch in Q3:

• Engines & Power Systems margins recovering from 12.4%. Partly. They reached 16.5%, but that is still below last year's 20.2%, and tariff refunds helped.
• How much spin-off cost keeps flowing through GAAP results. Much less than feared. Transaction costs fell to $18 million from $329 million in Q2. The new recurring standalone costs are now visible instead: $187 million of interest and the $54 million trademark fee.
• Whether cash covers about $200 million a quarter of interest plus buybacks. Cash covered the interest: the company generated $500 million of free cash flow in a quarter with $187 million of interest expense, and cash rose to $1,558 million. But no buybacks were made, so the second half of the test has not been run yet.

Q2's main point was that demand is not the constraint and output is. That still holds: backlog grew from $18.2 billion to $19.3 billion in one quarter while sales grew 2.7% from Q2.

Outlook

"Pro forma standalone" means the company restates the full year as if it had been independent since January, adding interest and standalone costs to the months it was still part of Honeywell.

The cash guidance gives the clearest test of Q4. With $500 million of free cash flow in Q3, the second-half range of $1.2–1.4 billion implies $700–900 million in Q4 alone. The sales guidance asks for more than Q3 delivered: sales grew about 6% in the first half and 2% in Q3, and keeping the full year at 4–5% requires Q4 growth to at least hold at Q3's pace, and likely pick up.

The CEO pointed to "encouraging signs from pacing suppliers" (the few mechanical suppliers whose output sets the pace for the whole company) and to qualifying more sources of materials. He said these position the company "for higher sales and output growth in 2027 and beyond." The company also announced a $500 million, 300,000-square-foot plant in Tempe, Arizona, due in late 2028. It is meant to bring complex machining, one of the constrained parts of its supply chain, in-house.

Our read. HONA has a demand surplus and an output deficit. Backlog grew 12% while sales grew 2%, and the gap widened again this quarter. Until the pacing suppliers deliver, sales growth stays low and costs stay high, and Engines & Power Systems will keep showing it first. Three things to watch in Q4: whether commercial aftermarket growth recovers above the low single digits now that orders are there; whether adjusted EBIT holds near Q3's $1.16 billion without another tariff refund; and when the first buybacks start, since $15.85 billion of debt and a negative equity balance of $2.49 billion leave less room than the $3.5 billion authorization suggests.
