• ON Semiconductor (NasdaqGS:ON) is expanding collaborations with Chinese automakers NIO and Geely Auto Group.
• The partnerships focus on next generation 900V electric vehicle platforms using ON’s EliteSiC technology.
• The news highlights closer integration between EV manufacturers and semiconductor suppliers in high voltage architectures.

For investors tracking ON Semiconductor at a current share price of $93.3, this development adds a fresh angle to the story around its role in electric vehicles. The stock has seen returns of 7.4% over the past week and 59.9% over the past month, with 64.6% year to date and 140.1% over the past year. Those numbers frame a company that is already drawing strong attention from the market as it deepens ties with major EV makers.

The expanded work with NIO and Geely places ON closer to the core of next generation 900V EV platforms, an area where efficiency and power management are critical. As these collaborations progress, investors may want to watch how adoption of EliteSiC solutions within high growth automotive markets develops and how that feeds into future updates from ON Semiconductor.

📰 Beyond the headline: 3 risks and 1 thing going right for ON Semiconductor that every investor should see.

This expanded work with NIO and Geely pushes ON deeper into system-level design for high voltage EVs, rather than just supplying individual chips. EliteSiC is a silicon carbide based power technology used to handle high voltages more efficiently than traditional silicon, which matters in 900V architectures where heat, charging speed, and range are key differentiators. For investors, this ties ON’s fortunes more closely to the success of Chinese EV platforms that use NIO’s 900V systems and Geely’s SEA-S architecture, and it reinforces ON’s focus on higher value power solutions aligned with long-term EV and AI themes mentioned in broader company narratives.

How This Fits Into The ON Semiconductor Narrative

• The deeper integration of EliteSiC into NIO and Geely platforms supports the idea that ON is winning EV design slots in China and pushing further into higher margin, power focused products that sit at the core of electrified transportation.
• Greater reliance on Chinese OEMs could amplify existing concerns about exposure to one region, adding sensitivity to EV demand, regulatory changes, or pricing pressure in that market.
• The specific focus on 900V architectures and SEA-S based vehicles is not fully captured in the broad EV and AI theme, and may add another layer of concentration risk around a small set of platforms and customers.

The Risks and Rewards Investors Should Consider

• ⚠️ Higher exposure to Chinese EV makers increases ON’s sensitivity to regulatory shifts, tariffs, and geopolitical friction between the US and China.
• ⚠️ Silicon carbide is a competitive area, with peers such as Wolfspeed, STMicroelectronics, and Infineon also targeting high voltage EV powertrains, which could pressure pricing and margins over time.
• 🎁 EliteSiC design wins across both NIO’s 900V platforms and Geely’s SEA-S architecture support ON’s push into higher value power solutions tied to long-term electrification trends.
• 🎁 Closer collaboration with automakers can shorten product cycles and deepen integration, which may help ON defend share against rivals and broaden its content per vehicle.

What To Watch Going Forward

From here, keep an eye on how many NIO and Geely models actually ship using 900V platforms with EliteSiC inside, and how that mix evolves over the next product cycles. Watch for any signs of pricing pressure in silicon carbide devices as more competitors ramp capacity, and track how ON manages customer and geographic concentration, given the weight of China in its EV story. Updates on additional EV platforms, either with these partners or new ones such as Tesla, BYD, or Volkswagen, will also be important signals for how diversified ON’s automotive design win pipeline becomes.
