Description of the Business

The Company produces products that are used in the aerospace (commercial and defense), commercial transportation, gas turbines, and other markets. Howmet seeks to provide its customers with innovative solutions through offering differentiated products such as airfoils with advanced cooling and coatings for extreme temperature applications; specially-designed fasteners for lightweight composite airframe construction, reduced assembly costs, and lightning strike protection; and lightweight aluminum commercial wheels. Its products and solutions include investment castings for jet engines and industrial gas turbines (nickel superalloys, titanium, and aluminum), including airfoils and structural parts; seamless rolled rings for jet engines (mostly nickel superalloys); fastening systems for aerospace, industrial and commercial transportation applications (titanium, steel, and nickel superalloys); forged jet engine components (e.g., jet engine disks); machined and forged aircraft parts (titanium and aluminum); and forged aluminum commercial vehicle wheels, all of which are sold directly to customers or through distributors.

Aerospace (Commercial and Defense) Market. Howmet’s largest market is aerospace, which represented approximately 70% of the Company’s revenue in 2025. The Company produces a range of high performance multi-materials, highly engineered products, and vertically integrated machined solutions for aero engines and airframe structures, ranging from investment castings, advanced coatings, seamless rings, forgings, titanium extrusions, and titanium mill products, to fasteners that hold aircraft together. Wingtip to wingtip, nose to tail, Howmet can produce more than 90% of all structural and rotating aero engine components. Modernization of the commercial and defense platforms is driven by an array of challenging performance requirements. With its precision engineering, materials science expertise, and advanced manufacturing processes, Howmet aims to help its customers achieve greater fuel economies, reduced emissions, passenger comfort, and maintenance efficiencies.

Commercial Transportation Market. The commercial transportation market represented approximately 15% of the Company’s revenue in 2025. The Company invented the forged aluminum truck wheel in 1948, and continues to advance technology to deliver breakthrough solutions that make trucks and buses lighter, more fuel efficient and sharper-looking. Howmet’s forged aluminum wheels are a leading choice for commercial trucks and mass transportation vehicles because they can reduce weight and save fuel. The strength of the Company’s rivets, bolts and fasteners offers another light-weighting solution that delivers performance.

Gas Turbines Market. The gas turbines market includes industrial gas turbines and oil and gas, which represented approximately 11% of the Company’s revenue in 2025. The gas turbines market constitutes turbine parts with advanced cooling and coatings for use in heavy-duty gas turbine units as well as small- to mid-sized gas turbine units. Turbines across these size ranges serve growing demand for electricity generation, driven by accelerating data center build-out.

In the fourth quarter 2025, the Company combined the revenue disclosure for the industrial gas turbine and oil & gas end markets into Gas Turbines. As a result of this change, the Company will no longer disclose the Industrial & Other end market. The revenue previously classified as general industrial is now classified as Other in our end market disclosures.

Other Market. The other market includes all other areas, which represented approximately 4% of the Company’s revenue in 2025.

Howmet has four reportable segments, which are organized by product on a worldwide basis: Engine Products, Fastening Systems, Engineered Structures and Forged Wheels.
