Vishay Precision Group
VPG · NYSE
INVESTABLE SPECULATIVE
Downstream Humanoid robotics theme generally (no single confirmed anchor yet)
Chokepoint Precision sensors, measurement systems, weighing solutions
Evidence Q1 2026 revenue +17.6% YoY to $84.4M; orders >$100M; backlog ~$125M
Real, US-listed, under-the-radar precision-component maker with growing robotics-tied revenue. Not a confirmed acquisition target — flagged as the right shape of company for this framework, not a prediction.
Ningbo Tuopu Group
601689 · Shanghai (SSE)
NOT INVESTABLE HIGH
Downstream Tesla (Optimus)
Chokepoint Linear/rotary actuator assembly (Tier 0.5 supplier)
Evidence Tesla = 35-40% of Tuopu total revenue
Deepest disclosed single-customer dependency found in the Optimus supply chain — exactly the shape of company a control-premium acquirer targets, but China-listed and not reachable via a standard US brokerage.
Sanhua Intelligent Controls
002050 · Shenzhen (SZSE) / Hong Kong (SEHK)
NOT INVESTABLE MEDIUM
Downstream Tesla (Optimus)
Chokepoint Joint modules / actuator components
Evidence $685M order placed by Musk personally, Oct 2025; new Mexico factory shipping 2026
Large forward commitment plus a dedicated near-shore facility is a real dependency signal, but China/HK-listed — not investable via StreetBeat/WF without international access.
