NN is a small diversified industrial manufacturer that makes high-precision metal components and assemblies for critical applications across automotive, electrical grid, medical, aerospace & defense, and general industrial end markets. Core products include tight-tolerance machined components, precision stampings, electrical contacts, connectors, and assemblies used in systems like power steering, braking, transmissions, and grid infrastructure. NN sells exclusively to manufacturers — including major automotive OEMs and Tier 1 suppliers, Siemens, Honeywell, Itron, medical device makers, and defense contractors. NN operates two segments: Mobile Solutions (~57% of revenue), which makes precision machined parts primarily for automotive powertrains and serves industrial and medical markets; and Power Solutions (~43% of revenue), which makes stamped electrical contacts, connectors, and assemblies for grid infrastructure, automotive, medical, and defense. NN makes money by converting raw metals into high-precision parts and charging a margin over materials, labor, and overhead. Profitability is driven by volume leverage on largely fixed capacity, mix improvement toward higher-margin defense and medical business, and ongoing cost reductions including a 20%+ reduction in salaried headcount since mid-2023. NN also holds a profitable China JV with Weifu/Bosch making fuel system components for Chinese OEMs including BYD. Because NN's parts are specified directly into customer platforms during the design phase — and switching requires costly re-certification — NN benefits from high customer retention and recurring revenue over multi-year production lifecycles.
