Howmet Aerospace is executing like a premium aerospace compounder, with Engine Products and Fastening Systems driving strong growth and margin expansion. Valuation remains the main restraint, even as earnings momentum and gas turbine demand stay powerful.
Howmet Aerospace (HWM) is a high-quality aerospace components supplier with strong medium-term growth, improving margins, and a durable position in engine products, fasteners, and industrial gas turbine parts. The investment case rests on 2026 Q2 revenue growth of 24%, organic growth of 21%, adjusted EBITDA growth of 39%, and adjusted EPS growth of 46%.
The strongest growth engine is Engine Products, where Q2 revenue rose 32% to $1.37B and segment adjusted EBITDA rose 51% to $517M. Gas turbine revenue increased 38%, commercial aerospace grew 28%, and spares revenue across commercial aerospace, defense aerospace, and gas turbines rose 37% to approximately $460M. These figures show that HWM is benefiting from both new production and the installed base of aircraft and engines already in service.
The main restraint is valuation. HWM trades at 67.5x trailing earnings and 54.9x forward earnings, while its free-cash-flow yield is 2.0%. That premium is supported by a PEG ratio of 0.8x, an eight-quarter streak of earnings beats, and analyst EPS estimates rising from $6.06 in 2027 to $8.81 in 2030. It is not supported by a large margin of safety at the current quoted price of $289.72.
For a moderate-risk investor with a medium-term horizon, HWM merits a Buy rating rather than a Strong Buy. The business is executing like a premium compounder, but the stock price already reflects a meaningful portion of that execution.
Howmet Aerospace (HWM) is a Pittsburgh-based industrial company founded in 1888. It employs approximately 25,430 people and operates across the United States, Japan, France, Germany, the United Kingdom, Mexico, Italy, Canada, Poland, and China.
The company operates through Engine Products, Fastening Systems, Engineered Structures, and Forged Wheels. Its products include airfoils, seamless rolled rings, turbine components, aerospace fasteners, titanium and nickel forgings, machined structures, and forged aluminum wheels.
HWM generated $8.25B of revenue in 2025, up from $4.97B in 2021. Over the same period, operating income increased from $866M to $2.13B, while net income rose from $258M to $1.51B. The improvement reflects a business mix increasingly weighted toward aerospace and high-value engineered components.
The 2026 growth profile is more concentrated than the corporate label suggests. Aerospace represented approximately 70% of 2025 revenue, while gas turbines contributed about 11%. Commercial transportation remains important through Forged Wheels, but its Q2 volume was down 8% year over year even as sequential volume improved 7%.
Engine Products is the core earnings asset. Q2 third-party sales rose 32% to $1.37B, adjusted EBITDA increased 51% to $517M, and the segment adjusted EBITDA margin reached 37.7%, up from 33.0% a year earlier. The segment's Q2 mix was 56% commercial aerospace, 18% defense aerospace, 24% gas turbines, and 2% other.
Fastening Systems produced Q2 revenue of $589M, up 37%, and adjusted EBITDA of $177M, up 40%. Its adjusted EBITDA margin was 30.1%. The CAM and Brunner acquisitions contributed to the reported growth, while management said total fastener growth remained in the double digits excluding acquisitions.
Engineered Structures is being managed for profitability rather than headline volume. Q2 revenue declined 13% to $269M after the Savannah disk forging facility was divested on March 31, 2026. Excluding that divestiture, revenue was approximately flat, while adjusted EBITDA margin improved to 23.8% from 22.1%.
Forged Wheels generated Q2 revenue of $316M, up 14%, and adjusted EBITDA of $88M, up 16%. Higher aluminum pass-through drove revenue growth, but volume declined 8% year over year. The 27.8% segment margin also faced a 360-basis-point year-over-year dilution from higher metal pass-through, which did not materially reduce EBITDA dollars.
The segment mix favors Engine Products and Fastening Systems, which posted the highest Q2 margins and the strongest growth. Engineered Structures adds a restructuring and portfolio-optimization story, while Forged Wheels adds commercial transportation recovery potential but also exposes HWM to aluminum pricing and truck production cycles.

The flagship product family is the turbine blade and related engine component portfolio within Engine Products. HWM supplies airfoils, seamless rolled rings, rotating parts, structural parts, and advanced coatings for aircraft engines and industrial gas turbines.
Management said HWM holds more than 50% of the global industrial gas turbine blade market. That position gives the company direct exposure to the sharp increase in gas turbine demand tied to electricity generation and data center power requirements. Q2 gas turbine revenue increased 38%, and management said all seven major customers had completed negotiations while some were revisiting their demand outlooks.
The product's value comes from precision, process control, and qualification. HWM produces equiaxed, directionally solidified, and single-crystal turbine blades, with single-crystal parts currently representing less than 5% of the turbine blade market according to management. The company is also expanding its ability to produce large core blades and apply multiple coating chemistries in a single process.
Spares strengthen the flagship product economics. Spares represented approximately 22% of HWM revenue through the first half of 2026, compared with about 21% of total revenue in 2025 and 17% in 2024. That rising installed-base contribution gives HWM a second revenue stream beyond new aircraft and engine production.
HWM's competitive advantage combines engineering know-how, long qualification cycles, product criticality, and manufacturing scale. The company's products are embedded in aircraft engines, airframes, defense platforms, and industrial gas turbines, where a part failure carries consequences far beyond the component's purchase price.
The company is investing ahead of demand. HWM built a new plant in Japan, expanded in Europe, and is adding equipment in Virginia. It also moved some nickel alloy work to create additional Virginia capacity for industrial gas turbine components and titanium castings.
Coating technology is another differentiator. HWM has expanded coating guns and pits during the past two to three years, and its Whitehall facility can apply multiple chemistries to internal and external blade surfaces in the same process. Management cited lead times of about three years for some advanced coating equipment, making early capacity commitments strategically important.
The innovation case is therefore less about a single new product launch and more about increasing content, yield, throughput, and technical complexity within existing product families. That approach fits HWM's Q2 result, where EBITDA grew faster than revenue and incremental margins reached 46%.
HWM is operating in a capacity-constrained aerospace supply chain. Q2 commercial aerospace revenue increased 28%, with organic growth of 26%, while management said aircraft orders continued to grow and the overall backlog increased despite Middle East volatility.
Capacity additions are staged over several years. New industrial gas turbine capacity already installed in Japan is expected to support growth during 2026 and 2027, while newer commitments are scheduled to contribute in 2028, 2029, and 2030. Management also said some machine-tool capacity had to be booked in advance to support future customer demand.
Capital spending is moving higher. HWM spent $453M on capital expenditures in 2025, reported Q2 2026 capital expenditures of $104M, and said full-year 2026 capital spending is expected to exceed $500M. Most of the spending is directed toward Engine Products and is backed by customer contracts.
The CAM fastener acquisition closed on April 6, 2026, for approximately $1.8B. HWM said the integration was on track, but the acquisition also introduced lower-margin business into Fastening Systems and increased leverage. That is a manageable trade-off, provided the planned 2027 optimization produces the stated synergies.
Supply-chain quality issues across aerospace support demand for qualified suppliers, but they also raise execution requirements. HWM's ability to add roughly 485 net employees in Engine Products during Q2 while increasing the segment margin to 37.7% is a favorable operating signal.
Commercial aerospace is the largest near-term market driver. HWM reported Q2 commercial aerospace growth of 28%, supported by both new builds and spares. Management cited potential Boeing 787 production at Rate 10 and an Airbus A350 rate moving from approximately 5 or 6 toward 8 or 9 over the next year.
Defense aerospace adds a second growth leg. HWM's Q2 defense aerospace revenue increased 11%, with organic growth of 7%, while 2025 defense revenue reached $1.5B, up 21%. Management specifically cited F-35 production and spares, as well as demand linked to PAC-3, THAAD, Tomahawk, missile engines, drones, and collaborative combat aircraft.
Industrial gas turbines are the most powerful non-aerospace catalyst. Q2 gas turbine revenue rose 38%, and management linked demand to electricity generation for data centers. HWM's more than 50% global turbine blade share gives the company a direct route to capture market growth, although the required capacity investments will raise capital intensity.
Commercial transportation is the weaker market. Q2 revenue rose 12% because of higher aluminum pass-through, but wheel volume fell 8% year over year. The 7% sequential volume increase in North America provides evidence of an early recovery, not a fully restored cycle.

HWM serves aircraft and engine manufacturers, defense contractors, industrial gas turbine customers, and commercial truck manufacturers. The 2025 filing identifies General Electric and Raytheon Technologies among aerospace customer concentration categories, while management referred to seven major industrial gas turbine customers in Q2.
Commercial aerospace customers include programs associated with Boeing and Airbus. HWM's products are used across narrow-body and wide-body aircraft, and management said much of the production equipment can support both aircraft types because the underlying casting, pressing, heat-treatment, and kiln processes are similar.
Defense customers are tied to established aircraft and missile programs. The Q2 discussion highlighted the F-35, PAC-3, THAAD, Tomahawk, legacy fighters, drones, and collaborative combat aircraft. This mix gives HWM exposure to both recurring sustainment demand and new defense production.
The customer relationship is strengthened by certification and qualification requirements. HWM's 2025 filing describes long product cycles, proprietary technologies, and participation across major engine and airframe platforms. Those characteristics support recurring orders, but they also make customer production schedules important to quarterly results.
HWM competes by product line rather than against one identical company across all four segments. Precision Castparts, owned by Berkshire Hathaway, competes in titanium alloys, precision forgings, seamless rolled rings, investment castings, airfoils, and aerospace fasteners.
ATI competes in titanium alloys and precision forgings, LISI Aerospace competes in aerospace fasteners, and Aubert & Duval competes in precision forgings. In Forged Wheels, Accuride and Speedline, part of Ronal Group, are named competitors.
HWM's strongest competitive position is in industrial gas turbine blades, where management cites more than 50% global share. Its Q2 Engine Products margin of 37.7% and Fastening Systems margin of 30.1% also show that the company is converting technical position and demand into high operating profitability.
Competition remains a real risk because the 2025 filing cites significant competition, new entrants, new technologies, and pricing pressure. HWM's response is scale, qualification history, process expertise, and capacity investment rather than low-cost manufacturing.
HWM's Q2 performance came against a difficult macro backdrop. Management cited higher interest rates, stronger inflation signals, Middle East conflict, and volatile jet fuel and gasoline prices. Despite those factors, HWM said customer demand had not changed and air freight volumes continued to strengthen.
Geopolitical risk is supporting HWM's defense exposure. The Q2 outlook cited stronger missile demand and solid F-35 production, while 2025 defense revenue grew 21%. The same geopolitical forces can raise fuel costs and disrupt trade, so the benefit is positive for defense demand but not uniformly positive for the entire portfolio.
Input costs remain visible in Forged Wheels. Q2 commercial transportation revenue rose 12% because higher aluminum costs were passed through, while the segment's margin percentage fell sequentially because of that pass-through. The result shows why revenue growth and earnings growth need to be separated in this business.
The longer-term macro setup is favorable for aircraft replacement, aftermarket maintenance, defense modernization, and data center power demand. HWM's 2026 results provide concrete evidence of each theme through commercial aerospace growth, spares growth, defense growth, and industrial gas turbine growth.
Howmet’s balance sheet earns an A- thanks to solid financial flexibility that supports continued growth investment without obvious leverage stress.

Get Full Access →Howmet Aerospace has become one of the stronger operating stories in aerospace manufacturing. Q2 revenue grew 24%, organic growth reached 21%, adjusted EPS rose 46%, and Engine Products produced a 37.7% adjusted EBITDA margin. The company is also converting demand into cash, with approximately $840M of free cash flow in the first half of 2026.
The investment case is anchored by more than one market. Commercial aerospace production and spares provide the largest growth base, defense programs add durability, and industrial gas turbines create a meaningful data center power exposure. The more than 50% global turbine blade share and rising aftermarket mix give HWM a competitive position that is difficult to replicate quickly.
The stock is therefore a Buy for a medium-term, moderate-risk portfolio, with our fair value estimate of $315. The business deserves a premium, but the 67.5x trailing earnings multiple means entry price still matters. HWM offers a credible path to wealth creation through earnings growth and cash generation, but the best returns will come from disciplined purchases rather than paying any price for an excellent aerospace supplier.
