1. Business Overview

RBC offers solutions that reduce friction, transfer motion, carry loads and control pressure and flow in demanding applications. While the bearing, gearing and precision component industry is a fragmented, multi-billion-dollar market, RBC focuses primarily on high-value, differentiated segments where its engineering and manufacturing prowess yield leading market positions:

• Aerospace/Defense (36% of fiscal 2025 net sales): RBC designs and manufactures precision bearings and essential systems for commercial and military aircraft, guided munitions, naval vessels, ground vehicles, space and satellite platforms. Many products are OEM-qualified—some sole-source—for the life of aircraft platforms. This segment divides into:
– Commercial aerospace: airframe actuation, engine shafts, flight controls and landing gear.
– Defense aerospace and ground/sea systems: fighter jets, helicopters, warship propulsion, armored vehicles, guided munitions and space applications.

• Industrial (64% of fiscal 2025 net sales): RBCs product suite serves construction and mining equipment (Caterpillar, Komatsu), food and beverage, material handling, warehousing, logistics, manufacturing automation, semiconductor equipment, power generation, waste/water management and more. Industrial sales are split roughly two-thirds aftermarket/distribution and one-third OEM.

By targeting specialized, value-add products—rod ends, roller bearings, thin-section ball bearings, mounted bearings, enclosed gearing, hydraulics/valves, collets—RBC secures higher margins and strong lifecycle revenue from replacement parts and services.

3. Risk Factors & Market Sensitivities

Cyclicality – RBCs markets are cyclical. Industrial OEM demand tracks capital spending in mining, construction and manufacturing. Commercial aerospace depends on airliner build rates and MRO cycles. Defense is sticky but may be reprioritized by government spending cuts.

Raw Material Costs & Tariffs – Stainless and chrome steel account for ~40% of factory costs. Steel price volatility and U.S./foreign tariffs may squeeze margins; surcharges and pricing pass-throughs lag market moves.

Customer Concentration – Top 10 customers represent ~44% of sales, including defense primes (Boeing, Airbus, Lockheed, Northrop) and industrial OEMs (Caterpillar, Komatsu). Loss of a major account or consolidation among buyers could impact revenues.

Warranty & Liability – Complex end-use applications carry product liability and recall risks, especially in aerospace. RBC maintains product liability insurance but not recall insurance.

Foreign Exchange & Global Exposure – 11% of sales were non-U.S. in fiscal 2025, mainly Europe, Canada and Mexico. Currency translation and transactions pose risks, partly hedged by cross currency swap.

4. Outlook

• First Quarter 2026 guidance: net sales of $424–434 million (4.4–6.8% growth).
• Strong commercial aerospace book-to-bill, early stages of build-rate upcycle and robust defense awards underpin backlog growth.
• Industrial distribution & aftermarket resilient; OEM softness in machinery and semicon should moderate.
• Continued margin expansion via lean initiatives, automation, price management and mix.
• Modest capex supporting growth and digital transformation.

Overall Outlook
RBC Bearings enters fiscal 2026 with momentum in its core aerospace/defense markets, strong aftermarket channels and solid operating cash flow. Managements proven track record of realizing synergies from acquisitions, combined with a growing service business, should help weather cyclicality. Vigilance on raw material, tariff and FX risks, plus prudent leverage management, will be critical.
