APD vs PPG: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of October 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: PPG 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. APD and PPG 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 APD and PPG 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.

Air Products and Chemicals is the third-largest industrial gases company in the world, behind Linde and Air Liquide. The company provides oxygen, nitrogen, argon, hydrogen, helium, and specialty gases to industrial customers across refining, chemicals, electronics, energy, and food processing. Unlike Linde and Air Liquide, Air Products made a particularly aggressive strategic bet on large-scale hydrogen infrastructure projects.

PPG Industries is a global leader in coatings and specialty materials, meaning it manufactures paints, coatings, and finishes rather than end products. In 2025 it reported net sales of about $15.9 billion, and effective at the end of 2024 it reorganized into three reportable segments: Global Architectural Coatings (paints for homes and buildings), Performance Coatings (aerospace, protective and marine, automotive refinish, and traffic solutions), and Industrial Coatings (automotive OEM, general industrial, and packaging coatings). Its products protect and finish everything from cars and aircraft to bridges, food and beverage cans, and house walls, giving it exposure to a broad mix of end markets rather than dependence on any single one. Because coatings are sold into manufacturing and construction, PPG's volumes are cyclical, but it competes on formulation, technology, brand, and service, which gives it pricing power to pass through raw-material costs over time.

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

• APD drivers: Hydrogen mega-project execution and retrenchment; Activist-driven strategic refocus.
• PPG drivers: Diversified coatings end markets; Pricing power and innovation.

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: Hydrogen demand may develop slower than the remaining mega-project capital commitments require, and exiting projects such as Louisiana can bring large write-downs; the quarter ended June 30, 2026 showed a reported net loss of about $1.44 billion even as adjusted earnings beat estimates. For PPG, the main risk is cyclicality: PPG's volumes depend on global manufacturing, construction, and auto production, so an industrial slowdown or weak housing and vehicle demand compresses sales, as the modest flat-to-low-single-digit 2026 organic guidance reflects.

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 APD if you believe its drivers more; PPG 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 APD and PPG guides.

APD. With reported earnings near zero after a large loss quarter, a trailing P/E is not meaningful; on forward adjusted EPS the stock trades around 21x, still a discount to Linde. At about $299 the shares are up about 19% in 2026 and below the average analyst target of about $342. The November 5 report carries consensus of about $3.61 of adjusted EPS on $3.33 billion of revenue, and investors will watch for progress on capex cuts and free cash flow.

PPG. Figures are approximate and tied to the asOf date; verify live numbers before acting. PPG is a mature, cyclical industrial, so its valuation tends to move with expectations for global manufacturing and construction demand more than with any single quarter; at about 12.6 times forward earnings and 11 times EV/EBITDA it trades below the high-teens multiples quality industrials often command. The dividend-aristocrat record and pricing power are genuine quality signals, but the case rests on margin execution, cost discipline, and a cyclical recovery in its end markets, with Q3 results due October 27, 2026.

Headline figures (approximate, October 2026): APD shows revenue (ttm) ~$12.6 billion (latest quarter ~+5% YoY), operating margin ~26%, net income (ttm, reported) ~-$47 million (incl. ~-$1.44B quarter), adjusted eps (quarter to jun 2026) $3.47 vs $3.34 expected; PPG shows revenue (ttm) ~$16.4 billion; Q2 2026 ~$4.5 billion, up ~7% year over year, 2026 outlook Adjusted EPS guided ~$7.70 to $8.10; consensus ~$7.89, margins Gross ~41%, operating ~14%, net ~9.6%, net income / eps ~$1.57 billion TTM; Q2 2026 adjusted EPS $2.23 vs ~$2.25 expected.

APD and PPG 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.
