ITEM 1. BUSINESS

RBC Bearings Incorporated

RBC Bearings Incorporated, together with its subsidiaries, is an international manufacturer and marketer of highly engineered precision bearings, components and essential systems for the aerospace, defense and industrial industries. Our precision solutions are integral to the manufacture and operation of most machines and mechanical systems, to reduce wear to moving parts, facilitate proper power transmission, reduce damage and energy loss caused by friction, and control pressure and flow. The terms “we,” “us,” “our,” “RBC” and the “Company” mean RBC Bearings Incorporated and its subsidiaries, unless the context indicates another meaning. While we manufacture products in all major categories, we focus primarily on the higher end of the bearing, gearing and engineered component markets where we believe our value-added engineering and manufacturing capabilities, and application expertise enable us to differentiate ourselves from our competitors and enhance profitability. We believe our expertise has enabled us to garner leading positions in many of the product markets in which we primarily compete. With 54 facilities in 11 countries, of which 38 are manufacturing facilities, we have been able to significantly broaden our end markets, products, customer base and geographic reach.

All quantitative data contained in this Annual Report on Form 10-K (the “Annual Report”) is stated in millions, except for share and per-share data, number of facilities, and headcount.

The Bearing, Gearing and Engineered Component Industry

The bearing, gearing and engineered component industry is a fragmented multi-billion-dollar market. Purchasers of bearings, gearing and engineered components include producers of commercial and military aircraft, submarines, military vehicles, energy equipment, warehousing and logistics systems, industrial equipment, automation systems, construction machinery, rail and transportation equipment, packaging and canning machinery, agriculture and mining equipment, and other forms of specialized equipment, as well as distributors who service the aftermarket for these products.

Demand for bearings, gearing and precision components in the diversified industrial market is influenced by growth factors in industrial machinery and equipment shipments, and construction, mining, energy, food and beverage, packaging and canning, semiconductor, and general industrial activity. In addition, usage of existing machinery will impact aftermarket demand for replacement products. In the commercial aerospace market, new aircraft build rates along with carrier traffic volumes worldwide determine demand for our solutions. Activity in the defense market is influenced by modernization programs necessitating spending on new equipment, as well as continued utilization of deployed equipment supporting aftermarket demand for replacement bearings, gearing and engineered components.

Customers and Markets

We serve a broad range of end markets where we can add value with our specialty precision bearings, essential systems and engineered components. We classify our customers into two principal categories: industrial and aerospace/defense. These principal end markets utilize a large number of both commercial and specialized bearings, gearings and engineered components. Although we provide a relatively small percentage of total bearings, gearings and engineered components supplied to each of our principal markets, we believe we have leading market positions in many of the specialized product markets in which we primarily compete. Financial information regarding geographic areas is set forth in Part II, Item 8, Note 19 of this Annual Report on Form 10-K.

Industrial Market (64% of net sales for the fiscal year ended March 29, 2025)

We manufacture bearings, gearing and engineered components for a wide range of diversified industrial markets, including multi-industry manufacturing, construction, metals and mining, aggregate and cement, food and beverage, oil and natural resource extraction, forest products, warehousing and logistics, grain, transportation, packaging and canning, semiconductor equipment, power generation, waste and water management, and other general industrial markets. Our products target market applications in which our engineering and manufacturing capabilities provide us with a competitive advantage in the marketplace.

Our largest industrial customers include Caterpillar, Komatsu and Halliburton and various aftermarket distributors including Motion Industries, Applied Industrial, Baldwin Supply, BDI and Purvis Industries. We believe that the diversification of our sales among the various segments of the industrial markets and channels reduces our exposure to downturns in any individual segment. We believe opportunities exist for growth and margin improvement in this market as a result of the introduction of new products, the expansion of aftermarket sales, and continued manufacturing process improvements.

Aerospace/Defense Market (36% of net sales for the fiscal year ended March 29, 2025)

We supply bearings and engineered components for use in commercial, private, and military aircraft and aircraft engines, guided weaponry, space and satellites, vision and optical systems, and military marine and ground applications.

We supply precision products for many of the commercial aircraft currently operating worldwide and are the primary bearing supplier for many of the aircraft OEMs’ product lines. Commercial aerospace customers generally require precision products, often constructed of special materials and made to unique designs and specifications. Many of our aerospace bearings and engineered component products are designed and certified during the original development of the aircraft being served, which often makes us the primary bearing supplier for the life of that aircraft.

We manufacture bearings and engineered components used by the U.S. Department of Defense (the “DOD”) and certain foreign governments for use in fighter jets, helicopters, naval vessels, gas turbine engines, armored vehicles, transport vehicles, guided weaponry, and space and satellite applications. We manufacture an extensive line of standard products that conform to many domestic military application requirements, as well as customized products designed for unique applications. Our bearings and engineered components are manufactured to conform to U.S. military specifications and are typically custom designed during the original product design phase, which often makes us the sole or primary supplier for the life of that product. Product approval for use on military equipment is often a lengthy process ranging from six months to six years.

Our largest aerospace and defense customers include the U.S. Department of Defense, Boeing, Airbus, Newport News Shipbuilding, Lockheed Martin, Northrop Grumman, Raytheon, Blue Origin and SpaceX and various aftermarket distributors including National Precision Bearing. We believe our strong relationships with OEMs help drive our aftermarket sales since a portion of OEM sales are ultimately intended for use as replacement parts. We believe that growth and margin expansion in this market will be driven primarily by expanding our international presence, new commercial aircraft introductions, new products, share gains, and the refurbishment and maintenance of existing commercial and military aircraft.

In fiscal 2025, approximately 3% of our net sales were made directly, and we estimate that approximately an additional 9% of our net sales were made indirectly, to the U.S. government. The contracts or subcontracts for these sales may be subject to renegotiation of profit or termination at the election of the U.S. government. Based on experience, we believe that no material renegotiations or refunds will be required. See Part I, Item 1A. “Risk Factors – Future reductions or changes in U.S. government spending could negatively affect our business” of this Annual Report on Form 10-K.

Our two reportable business segments are aligned with the end markets for our products. Operating results for the segments are evaluated regularly by our chief operating decision maker in determining resource allocation and assessing performance. The following table provides a summary of our two reportable business segments:

Products

Bearings, gearing and engineered components are employed to perform several functions including reduction of friction, transfer of motion, carriage of loads, and control of pressure and flows. We design, manufacture and market a broad portfolio of bearings, gearing and engineered components.

Plain Bearings. Plain bearings are primarily used to rectify inevitable misalignments in various mechanical components, such as aircraft controls, helicopter rotors, or heavy mining and construction equipment. Such misalignments are either due to machining inaccuracies or result when components change position relative to each other. Plain bearings are produced with either self-lubricating or metal-to-metal designs and consist of several sub-classes, including rod end bearings, spherical plain bearings and journal bearings.

Roller Bearings. Roller bearings are anti-friction products that utilize cylindrical rolling elements. We produce three main designs: tapered roller bearings, needle roller bearings and needle bearing track rollers, and cam followers. We offer several needle roller bearing designs that are used in both industrial applications and certain U.S. military aircraft platforms where there are high loads and the design is constrained by space considerations. A significant portion of our sales of needle roller bearings is to the aftermarket rather than to OEMs. Needle bearing track rollers and cam followers have wide and diversified use in the industrial market and are often prescribed as a primary component in articulated aircraft wings.

Ball Bearings. Ball bearings are devices that utilize high precision ball elements to reduce friction in high-speed applications. We specialize in four main types of ball bearings: high precision aerospace, airframe control, thin section, and industrial ball bearings. High precision aerospace bearings are primarily sold to customers in the defense industry that require more technically sophisticated bearing products providing a high degree of fault tolerance given the criticality of the applications in which they are used. Airframe control ball bearings are precision ball bearings that are plated to resist corrosion and are qualified under a military specification. Thin section ball bearings are specialized bearings that use extremely thin cross sections and give specialized machinery manufacturers many advantages. We produce a general line of industrial ball bearings sold primarily to the aftermarket.

Mounted Bearings. Mounted bearings are fully assembled bearings with a wide range of shaft attachment methods, rolling elements, housing materials and configurations offering a variety of sealing solutions. Mounted bearing products include mounted ball bearings, mounted roller bearings and mounted plain bearings, and are used in light to heavy loads, and in clean, corrosive or harsh environments. Mounted roller bearings are pre-machined to allow field installation of the Dodge bearing sensor, adding remote monitoring capability in difficult to access applications and unsafe environments. Applications include unit and bulk material handling, industrial air handling, large rotor fans, food processing, roll-out tables, and forest pulp and paper processing equipment.

Enclosed Gearing. We provide a broad range of enclosed gearing product lines including Quantis Gearmotor (helical style gearing with modular configurations and a variety of mounting methods), Torque Arm (shaft-mount gearing with helical style gearing and v-belt input for first stage reduction), Tigear (single reduction, right angle gear reducers with worm style gearing), MagnaGear & Maxum (parallel reducers with helical and planetary style gearing) and Controlled Start Transmission (planetary style gearing with hydraulic clutch package used for soft starting large conveyors). Applications include unit and bulk handling, food processing, roll-out tables, and forest pulp and paper processing equipment.

Motion Control Components. Power transmission components are of three types: mechanical drive components (offering V belt sheaves, synchronous sprockets, bushings and belts) used to change rotational speed between two pieces of equipment; couplings used to transmit torque between two rotating pieces of equipment, such as a motor and a gearbox; and conveyor components, which transfer torque from the mechanical drive equipment to the conveyor belt in bulk material handling applications. Applications include unit and bulk material handling, industrial air handling, large rotor fans, food processing, roll-out tables, and forest pulp and paper processing equipment. We also provide actuation components to customers within our commercial aerospace and space markets.

Engineered Components. Engineered components include highly engineered hydraulics and valves, fasteners, precision mechanical components and machine tool collets. Engineered hydraulics and valves are used in aircraft and submarine applications and aerospace and defense aftermarket services. Precision mechanical components are used in all general industrial applications where some form of movement is required. Machine tool collets are cone-shaped metal sleeves used for holding circular or rod-like pieces in a lathe or other machine that provide effective part holding and accurate part location during machining operations.

Product Design and Development

We produce specialized bearings and engineered components that are often tailored to the specifications of a customer or application. Our sales professionals are highly experienced engineers who collaborate with our customers to develop bearing and engineered component solutions. The product development cycle can follow many paths, which are dependent on the end market or sales channel. The process normally takes between three and six years from concept to sale depending upon the application and the market. A typical process for a major OEM project begins when our design engineers meet with the customer at the machine design conceptualization stage and work with them through the conclusion of the product development.

Often, at the early stage, a bearing or engineered component design is produced that addresses the expected demands of the application including load, stress, heat, thermal gradients, vibration, lubricant supply, pressure and flows, and corrosion resistance, with one or two of these environmental constraints being predominant in the design consideration. A bearing or engineered component design must perform reliably for the period of time required by the customer’s product objectives.

Once a bearing or engineered component is designed, a mathematical simulation is created to replicate the expected application environment and thereby allow optimization with respect to these design variables. Upon conclusion of the design and simulation phase, samples are produced and laboratory testing commences at one of our test laboratories. The purpose of this testing phase is not only to verify the design and the simulation model but also to allow further design improvement where needed. The last phase is field testing by the customer, after which the product is ready for sale.

For many of our Aerospace/Defense products, the culmination of this lengthy process is the receipt of a product approval or certification, generally obtained from either the OEM, the DOD or the Federal Aviation Administration (“FAA”), which allows us to supply the product to the OEM customer and to the aftermarket. We currently have a significant number of such approvals, which often gives us a competitive advantage, and in many of these instances we are the only approved supplier of a given bearing or engineered component.

Manufacturing and Operations

Our manufacturing strategies are focused on product reliability, quality, safety and service. Custom and standard products are produced according to manufacturing schedules that ensure maximum availability of popular items for immediate sale while carefully considering the economies of lot production and special products. Capital programs and manufacturing methods development are focused on quality improvement, production costs, safety and service. Ongoing review of product line production performance assurance an environment of continue attainment of profitability and quality goals.

Capacity. Our plants currently run on a full first shift with second and third shifts at select locations to meet the demands of our customers. We believe that current capacity levels and future annual estimated capital expenditures on equipment up to approximately 3.0% to 3.5% of net sales should permit us to effectively meet demand levels for the foreseeable future.

Inventory Management. We operate an inventory management program designed to balance customer delivery requirements with economically optimal inventory levels. In this program, each product is categorized based on characteristics including order frequency, number of customers and sales volume. Using this classification system, our primary goal is to maintain a sufficient supply of standard items while minimizing costs. In addition, production cost savings are achieved by optimizing plant scheduling around inventory levels and customer delivery requirements. This leads to more efficient utilization of manufacturing facilities and minimizes plant production changes while maintaining sufficient inventories to service customer needs.

Sales, Marketing and Distribution

Our marketing strategy is aimed at increasing sales within our two primary markets, targeting specific applications in which we can exploit our competitive strengths. To affect this strategy, we seek to expand into geographic areas not previously served by us and we continue to capitalize on new markets and industries for existing and new products. We employ a technically proficient sales force and utilize marketing managers, product managers, customer service representatives and product application engineers in our selling efforts.

We have developed our sales force through the hiring of sales personnel with prior industry experience, complemented by an in-house training program. We intend to continue to hire and develop expert sales professionals and strategically locate them to implement our expansion strategy. Today, our direct sales force is located to service North America, Europe, Asia, Australia and Latin America and is responsible for selling all of our products. This selling model leverages our relationship with key customers and provides opportunities to market multiple product lines to both established and potential customers. We also sell our products through a well-established, global network of industrial and aerospace distributors. This channel primarily provides our products to smaller OEM customers, aftermarket customers and the end users of bearings and engineered components that require local inventory and service. We intend to continue to focus on building distributor sales volume.

The Company has a joint venture in North America focused on joint warehouse and transportation logistics and e-business services. The e-business service focuses on information and business services for authorized distributors in the Industrial segment.

The sale of our products is supported by a well-trained and experienced customer service organization, which provides customers with instant access to key information regarding their purchases. We also provide customers with updated information through our website, and we have developed on-line integration with specific customers, enabling more efficient ordering and timely order fulfillment for those customers.

We sto
