DPC vs HWM: How DPC Holdings PLC and Howmet Aerospace 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: HWM 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. DPC and HWM 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 DPC and HWM 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.

Doncasters was founded in 1778 in Derby, England, and its modern business is making the parts that sit in the hottest, most stressed section of a jet engine or an industrial gas turbine: single-crystal and equiaxed turbine blades, vanes, structural castings, turbine frames, housings and airfoils, plus the nickel- and cobalt-based superalloy feedstock those castings are poured from. A third business line makes turbocharger wheels for engine manufacturers. The company reports in three segments, Engine Products North America (roughly 60% of revenue), Engine Products Europe (roughly 30%) and Turbo Wheels (roughly 10%), across 14 principal facilities with about 3,077 employees. Customers are the engine and turbine primes themselves: GE Aerospace, Pratt & Whitney, Rolls-Royce, Safran, Honeywell, Siemens Energy, GE Vernova, Ansaldo Energia and Doosan. About 70% of 2025 revenue sat under long-term agreements, and the moat is regulatory qualification rather than brand: once a casting is certified into an engine program, replacing the supplier is a multi-year engineering and re-certification exercise.

Howmet Aerospace is a manufacturer of advanced engineered components for the aerospace and transportation industries. It is a leading maker of investment-cast turbine blades and structural castings for jet engines, engineered fastening systems used to hold aircraft together, aluminum and titanium structural parts, and forged aluminum wheels for commercial trucks. Howmet's products are highly engineered, precision metal parts that operate in extreme temperature and stress environments, particularly the hot sections of jet engines. The company makes money supplying these mission-critical components to engine makers and airframers for new aircraft production, and it earns substantial recurring spares and aftermarket revenue as engines are maintained over their long lives. Howmet was formed from the breakup of the old Arconic and Alcoa lineage and is now a focused aerospace and transportation supplier headquartered in Pittsburgh, Pennsylvania. It is widely viewed as a high-quality aerospace components company leveraged to rising commercial aircraft build rates and air travel.

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

• DPC drivers: Narrowbody engine output and the hot-section aftermarket; Industrial gas turbine demand tied to power for data centres.
• HWM drivers: Commercial aerospace ramp; Engine spares and aftermarket.

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 most immediate risk is the price itself: at roughly 9 times trailing sales and well north of 50 times 2025 adjusted EBITDA, the stock trades above the average broker target, and Morgan Stanley opened at Equalweight with a $47 objective against a market price near $57. For HWM, howmet is heavily exposed to commercial aerospace, so any downturn in air travel, airline financial stress, or a slowdown at Boeing and Airbus, including production problems or order cancellations, would reduce demand.

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 DPC if you believe its drivers more; HWM 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 DPC and HWM guides.

DPC. The multiple is the whole argument. Priced at $33, the IPO valued the group near $4.2 billion, and at about $57 the market has effectively doubled that in six weeks without any public quarterly report to justify it, which is why the average of the July initiations (Jefferies at $56, Rothschild Redburn at $53.50, RBC at $53, Morgan Stanley at $47) sits below the trading price. On trailing GAAP figures the company loses money, so any valuation case has to run through adjusted EBITDA and an assumption that interest expense falls as the post-IPO balance sheet is repaired. Whether the August 11 report validates the first-quarter acceleration to about 26% growth is the near-term swing factor.

HWM. Howmet trades at a premium valuation versus traditional industrials, reflecting its leverage to the commercial aerospace recovery, expanding margins, growing high-margin aftermarket revenue, and strong free cash flow. The market pays up for the structural growth and improving profitability, so the multiple is sensitive to the pace of aircraft build rates and any aerospace cyclicality. The premium leaves limited margin for execution missteps.

Headline figures (approximate, August 2026): DPC shows revenue (ttm) ~$886 million through late March 2026, up ~12% year over year, fy2025 revenue ~$837 million, up ~12% from ~$746 million in 2024, adjusted ebitda (2025) ~$138 million, a ~16.5% margin, on gross profit of ~$193 million, gaap net income (ttm) ~-$167 million, after a ~-$173 million net loss in 2025; HWM shows revenue (ttm) ~$8 billion, operating margin ~22%, net income (ttm) ~$1.3 billion, p/e (ttm) ~40x.

DPC and HWM 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 DPC and HWM exposure against your real portfolio. It is not an investment adviser.
