How Does Honeywell Technologies Make Money?
No single line supplies a majority of revenue: the largest, Aerospace Technologies, is 47%, which spreads Honeywell Technologies's exposure across several demand drivers. Between fiscal 2024 and 2025, Energy and Sustainability Solutions grew fastest (+18.5%) and Industrial Automation slowest (-6.5%), so the revenue mix tilts toward Energy and Sustainability Solutions while that gap lasts.
| Segment | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
|---|---|---|---|---|
| Aerospace Technologies | $17.5 billion | $15.5 billion | 46.8% | 13.3% |
| Industrial Automation | $9.4 billion | $10.1 billion | 25.1% | -6.5% |
| Building Automation | $7.4 billion | $6.5 billion | 19.7% | 12.6% |
| Energy and Sustainability Solutions | $3.1 billion | $2.6 billion | 8.4% | 18.5% |

| Product | $24.5 billion | $22.8 billion | 65.5% | 7.3% |
| Service | $12.9 billion | $11.9 billion | 34.5% | 8.8% |

What the Segment Figures Do Not Show
The rows above add up to 100% of Honeywell Technologies's reported revenue for fiscal 2025; the difference is intersegment eliminations, corporate revenue or items the company reports outside its segments. Segment definitions are management's choice and change when a company reorganizes, in which case it restates prior years in the next filing, so a multi-year comparison should use the figures from a single filing. Revenue shows where sales come from, not where profit or cash is earned: a small segment can carry most of the margin.
Where These Numbers Come From
Every figure on this page is a value Honeywell Technologies reported in the segment note and revenue disclosures of its Form 10-K filed February 17, 2026 (accession 0000773840-26-000013), read from the SEC's Financial Statement Data Sets. The prior-year column is the comparative figure from that same filing, so it reflects any restatement for a change in segments. Category names are the company's own XBRL labels, lightly reformatted for reading.
Rows that only total other rows (for example a "Products" line beside the individual products) are left out so nothing is counted twice. This page is educational and describes reported history for fiscal 2025; it is not a forecast or a recommendation.
