HON vs REZI: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

Reading it: REZI is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. HON and REZI share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined HON and REZI exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

Honeywell International is a diversified industrial technology conglomerate that makes a broad range of products and software across aerospace, building automation, energy and sustainability, and industrial automation. Its Aerospace segment supplies engines, avionics, and systems for commercial and defense aircraft and earns recurring aftermarket revenue servicing them. Its Building Automation business sells controls, sensors, fire and security systems for commercial buildings. Energy and Sustainability Solutions includes specialty chemicals, materials, and process technologies, while Industrial Automation covers warehouse and process control, sensing, and the productivity (barcode scanning) business. Honeywell makes money from a mix of equipment sales, long-cycle projects, recurring aftermarket service, and growing software offerings. The company has been reshaping its portfolio, spinning off and acquiring businesses to focus on aerospace, automation, and energy transition. Founded in its modern form through a 1999 merger and headquartered in Charlotte, North Carolina, Honeywell is a large, broadly held industrial blue chip.

Resideo Technologies develops, manufactures, and sells comfort, energy-management, and safety-and-security solutions for homes and small businesses under brands including Honeywell Home, First Alert, BRK, Braukmann, and Resideo. Its products include thermostats and temperature and humidity controls, water and air solutions, smoke and carbon-monoxide detectors, residential security systems, and video cameras. The company runs two segments: Products and Solutions (the branded hardware plus cloud and software) and ADI Global Distribution, a large omnichannel wholesaler of security, AV, and smart-living products serving over 100,000 professional-installer customers. Resideo was spun out of Honeywell in 2018 and expanded its smart-living footprint by acquiring Snap One (owner of the Control4 platform) for about $1.4 billion in 2024.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• HON drivers: Aerospace aftermarket strength; Portfolio reshaping and software.
• REZI drivers: ADI Global Distribution spin-off; Branded products and smart-living platform.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: As a diversified industrial, Honeywell is exposed to the broad economic cycle, with several segments sensitive to construction, manufacturing capex, and energy markets. For REZI, resideo carries meaningful leverage taken on for the Snap One deal, and integration plus the pending ADI separation add execution and complexity risk.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick HON if you believe its drivers more; REZI if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the HON and REZI guides.

HON. Honeywell trades at a valuation typical of a high-quality diversified industrial, reflecting solid margins, strong cash generation, a durable aerospace aftermarket, and a reliable dividend, balanced against modest organic growth and cyclical exposure. The market values its quality and stability while watching whether portfolio reshaping and software can lift growth above the broad industrial average.

REZI. Resideo trades around a mid-single-digit adjusted-EBITDA multiple, low relative to many industrials, which reflects its leverage, cyclicality, and the uncertainty around the ADI separation. Bulls argue the sum-of-the-parts is worth more once ADI is a standalone listing, while skeptics point to a 2025 GAAP net loss and contested acquisition accounting. Figures are approximate and as of JULY 2026.

Headline figures (approximate, early 2026): HON shows revenue (ttm) ~$39 billion, operating margin ~20%, net income (ttm) ~$5.5 billion, p/e (ttm) ~22x; REZI shows revenue (2025) ~$7.47B, 2026 revenue guidance ~$7.8B-$7.9B, adjusted ebitda (2025) ~$833M, 2026 adjusted eps guidance ~$3.00-$3.20.

HON and REZI are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined HON and REZI exposure against your real portfolio. It is not an investment adviser.
