Darker bar: ahead of the other company on that measure.
Nabtesco is a Japanese precision-reducer maker (~$1.3B group revenue) supplying RV reducers for large and mid robot joints, with a share estimated at 35-60% depending on scope definition, and it supplies nearly every major robot OEM. It is doubling its RV reducer production capacity by 2026 citing humanoid demand, with its precision segment up JPY 4.8bn in Q1-26 on auto and semiconductor recovery. It is a components-scale incumbent in the motion supply chain.
