Overview

Howmet is a leading global provider of advanced engineered solutions for the aerospace and transportation industries. The Company’s primary businesses focus on jet engine components, aerospace fastening systems, and airframe structural components necessary for mission-critical performance and efficiency in aerospace and defense applications, as well as forged aluminum wheels for commercial transportation. Howmet’s technological capabilities support the innovation and growth of next-generation aerospace programs. Its differentiated technologies enable lighter, more fuel-efficient aircraft and commercial trucks to operate with a lower carbon footprint and support more sustainable air and ground transportation.

Howmet is a global company operating in 19 countries. Based upon the country where the point of shipment occurred, North America and Europe generated 72% and 22%, respectively, of Howmet’s sales in 2025. In addition to the United States, Canada, and Mexico in North America and France, United Kingdom, Hungary, and Germany in Europe, Howmet has operating activities in numerous other countries and regions, including Japan and China.

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.

Patents, Trade Secrets, and Trademarks

The Company believes that its domestic and international patent, trade secret and trademark assets provide it with a significant competitive advantage. The Company’s rights under its patents, as well as the products made and sold under them, are important to the Company as a whole and, to varying degrees, important to each business segment. The patents owned by Howmet generally concern particular products, manufacturing equipment, or techniques. Howmet’s business as a whole is not, however, materially dependent on any single patent, trade secret, or trademark. As a result of product development and technological advancement, the Company continues to pursue patent protection in jurisdictions throughout the world. As of the end of 2025, the Company’s worldwide patent portfolio consisted of approximately 1,020 granted patents and 180 pending patent applications.

The Company also has a significant number of trade secrets, mostly regarding manufacturing processes and material compositions that give many of its businesses important advantages in their markets. The Company continues to strive to improve those processes and generate new material compositions that provide additional benefits. With respect to domestic and international registered trademarks, the Company has many that have significant recognition within the markets that are served. Examples include the name Howmet® metal castings, Huck® fasteners, and Dura-Bright® wheels with easy-clean surface treatments. As of the end of 2025, the Company’s worldwide trademark portfolio consisted of approximately 1,590 registered trademarks and 70 pending trademark applications. Following the Alcoa Inc. Separation Transaction, the Company retained the Alcoa Wheels® business and, pursuant to a Trademark License Agreement, is the exclusive licensee of the “Alcoa” name and logo for use with the wheels, hubs, and related products that we manufacture. The Company’s rights under its trademarks are important to the Company as a whole and, to varying degrees, important to each business segment.

Competitive Conditions

The Company’s segments - Engine Products, Fastening Systems, Engineered Structures, and Forged Wheels - are subject to substantial and intense competition in the markets they serve. Although Howmet believes its advanced technology, manufacturing processes, and experience provide advantages to Howmet’s customers, such as high quality and superior mechanical properties that meet the Company’s customers’ most stringent requirements, many of the products Howmet makes can be produced by competitors using similar types of manufacturing processes as well as alternative forms of manufacturing. Despite intense competition, Howmet continues as a market leader in most of its principal markets. We believe that factors such as Howmet’s technological expertise, state-of-the-art capabilities, capacity, quality, engaged employees, and long-standing customer relationships enable the Company to maintain its competitive position.

Principal competitors include Berkshire Hathaway Inc., through its 2016 acquisition of Precision Castparts Corporation and subsidiaries, for titanium and titanium-based alloys, precision forgings, seamless rolled rings, investment castings, including airfoils, and aerospace fasteners; VSMPO (Russia) for titanium and titanium-based alloys and precision forgings; ATI Inc.’s High-Performance Materials & Components segment for titanium and titanium-based alloys and precision forgings; Lisi Aerospace (France) for aerospace fasteners; and Aubert & Duval (part of Airbus, Safran, and Tikehau Capital) for precision forgings. Other competitors include Doncasters Group Limited (U.K.) and Consolidated Precision Products Corp. (owned by Warburg Pincus and Berkshire Partners) for investment castings; Weber Metals, Inc. (part of Otto Fuchs) for precision forgings; and Forgital Group and Frisa (Mexico) for seamless rings.

Forged Wheels competes against aluminum and steel wheel suppliers in the commercial transportation industry under the product brand name Alcoa® Wheels for the major regions that it serves (North America, Europe, Japan, China, South America, and Australia). Its larger aluminum wheel competitors are Accuride Corporation, Speedline (member of the Ronal Group), Nippon Steel Corporation, Dicastal North America, Inc., Alux Co., Ltd., and Wheels India Limited.

In recent years, Forged Wheels has seen an increase in the number of aluminum wheel suppliers (both forged and cast aluminum wheels) from China, Taiwan, India, South Korea, and Turkey attempting to penetrate the global commercial transportation market.

Several of Howmet’s largest customers have captive superalloy furnaces for producing airfoil investment castings for their own use. Many other companies around the world also produce superalloy investment castings, and some of these companies currently compete with Howmet in the aerospace and other markets, while others are capable of competing with the Company should they choose to do so.

International competition in the investment castings, fasteners, rings and forgings markets may also increase in the future as a result of strategic alliances among engine original equipment manufacturers (“OEMs”), aero-structure prime contractors, and overseas companies, especially in developing markets, particularly where “offset” or “local content” requirements create purchase obligations with respect to products manufactured in or directed to a particular country.

Attracting and recruiting candidates through workforce planning, increased hiring efficiency and effective onboarding have been a priority for the Company. New technology that increases the automation of job postings enables us to more widely disseminate our job vacancies to various partners and job boards, including our campus recruitment platform that helps us to proactively reach a broad talent network of students and schools across the United States. The Company remains committed to its military recruiting, adding additional partnerships in 2025, including the U.S. Department of War SkillBridge Program that provides transitioning service members the opportunity for training and development with potential employers. Additional technologies such as recruiting booster text capabilities facilitate communicating with candidates quickly and efficiently. To retain new talent, the Company offers an onboarding program to develop a sense of belonging, teamwork, and productivity. The Company offers increasingly more robust leadership and other development opportunities for our team members. To bolster our operations internal talent pipeline, we created two new development programs, the Frontline Leader Program and the Plant Manager Development Initiative. Additionally, the Company expanded its tuition assistance program in 2025 to now include reimbursement for a wide variety of certifications. We believe providing employees with avenues to new skills contributes to increased motivation and engagement, resulting in higher employee retention.

The Company supports our employees having ownership in their development to create rewarding careers that draw on their aptitudes and support their ambitions. Our development process framework provides tools and resources to identify career options, skills gaps and actions they can take to progress within the Company. Using a human capital management platform, employees can build a professional profile to share their career aspirations and learn new skills. This platform allows us to align employee goals and growth with the Company’s future business needs so that we can pinpoint potential successor candidates and build their readiness for future roles. We use a data-driven approach to track how employees are progressing through the organization. We seek to identify high performers and support their development into potential future leaders, focusing on providing opportunities to all individuals. A valuable component of development is Howmet’s mentoring program, which builds readiness for future leaders. Our talent review and succession planning process is an ongoing priority, sponsored and led by our Chief Executive Officer with oversight by the Board of Directors.

Howmet’s strong health and safety culture empowers our employees and contractors to take personal responsibility for their actions and the safety of their coworkers. This culture is supported by internal policies, standards, rules, and procedures that clearly articulate our stringent requirements for working safely in all our worldwide facilities. The Company embeds annual health and safety goals and objectives into its operating plans to progress toward our ultimate goal of zero incidents. We use various risk identification, assessment, and control processes to reduce the likelihood of safety and health incidents in the workplace, with prioritization on the prevention of fatality and serious injury.
