CMC vs Q: How Commercial Metals Company and Qnity Electronics, Inc. Compare (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: CMC 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. CMC and Q 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 CMC and Q 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. Walnut is not an investment adviser.

Commercial Metals Company is a Texas-based, vertically integrated steel and metals business built around electric-arc-furnace (EAF) mini-mills and micro-mills that melt recycled scrap into long steel products, primarily reinforcing bar (rebar) and merchant bar used in construction and infrastructure. It reports in three segments: North America Steel Group (its largest, spanning mills, fabrication, and recycling), Europe Steel Group (mills in Poland), and the Emerging Businesses Group (higher-margin, value-added products such as performance reinforcing steel, ground stabilization, and construction accessories). Because most of its output is long steel tied to nonresidential building and public works, CMC's results track construction activity, steel product metal margins (the spread between selling prices and scrap costs), and the broader economic cycle more than any single company-specific product.

Qnity Electronics, Inc. (NYSE: Q) sells the materials that go into making chips and the interconnects that link them. It runs two segments. Semiconductor Technologies supplies process consumables used inside fabs: chemical mechanical planarization (CMP) pads and slurries, photoresists and lithography chemistries, specialty gases, deposition materials and cleaning chemistries, sold to logic foundries, memory makers and integrated device manufacturers. Interconnect Solutions supplies the materials that sit around and between chips: Kapton polyimide films, Pyralux flexible circuit laminates, Riston dry film photoresist, metallization chemistries, Interra embedded capacitor laminates and the Laird thermal interface and EMI shielding lines, sold into advanced packaging, printed circuit boards, data center hardware, smartphones, autos and industrial electronics. Both segments are consumable, not capital equipment, which means revenue tracks how many wafers and boards are actually being processed rather than how many tools were bought in a given year. Geographic mix is heavily Asian: China is roughly 33 percent of sales, the broader Asia Pacific region is around 46 percent, the United States around 12 percent and Europe, Middle East and Africa around 8 percent.

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

• CMC drivers: US construction, infrastructure, and reshoring demand; TAG margin-improvement program.
• Q drivers: AI packaging is lengthening the path every chip takes; Advanced nodes are pulling the process consumables business.

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: The dominant risk is cyclicality: CMC's earnings track construction activity and steel metal margins, so a slowdown in nonresidential building, higher interest rates that stall projects, or a compression in the product-to-scrap spread can cut profits quickly. For Q, valuation carries most of the near-term risk: near 48 times trailing GAAP earnings and roughly 30 times the midpoint of management's own 2026 adjusted EPS guidance, the shares embed continued high-teens to low-twenties growth, and the stock has already traded in a wide band since listing, with a 52-week range spanning roughly $70 to $177.

Pick CMC if you believe its drivers more; Q 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 CMC and Q guides.

CMC. Figures are approximate and tied to the asOf date; verify live numbers before acting. Reported fiscal 2025 earnings were heavily distorted by the one-time Pacific Steel litigation charge, so trailing net income and any P/E built on it understate underlying operations; the sequentially stronger Q1 fiscal 2026 is a cleaner read on run-rate profitability. As with any cyclical steel producer, valuation multiples mean less than where construction demand and steel metal margins sit in the cycle, and the litigation outcome remains an open variable.

Q. The gap between roughly $2.79 of trailing GAAP earnings per share and roughly $4.40 to $4.60 of guided 2026 adjusted EPS is the single most important thing to understand about Qnity's headline multiples: on GAAP the shares trade near 48 times, on guided adjusted earnings closer to 30 times. The difference is mostly intangible amortization inherited from acquisitions DuPont made (Laird Performance Materials among them) plus one-time separation and standalone-setup costs, so the adjusted figure is the closer proxy for cash economics while the GAAP figure is the more conservative anchor. Adding roughly $4 billion of spin-off debt, the enterprise value sits near $32 billion, or roughly 19 times the midpoint of guided 2026 adjusted operating EBITDA, which is a premium to diversified specialty chemicals and closer to how dedicated semiconductor materials suppliers are priced.

Headline figures (approximate, Jul 2026): CMC shows net sales (fy2025, ended aug 2025) approximately $7.8 billion, net earnings (fy2025) approximately $84.7 million (about $0.74 diluted EPS), depressed by a roughly $274 million after-tax litigation charge, q1 fy2026 eps approximately $1.84, reported above analyst expectations, dividend quarterly cash dividend of $0.20 per share (about $0.80 annualized), a modest yield near 1%; Q shows market cap ~$28.1B, revenue (ttm) ~$5.21B, up ~15% year over year, q2 2026 net sales ~$1.43B, up ~22% year over year, q2 2026 adjusted operating ebitda margin ~30.2% (~$431M).

CMC and Q 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.
