ON Semiconductor (ON) is back in focus after Sungrow selected its EliteSiC silicon carbide hybrid power modules for the new PowerTitan 3.0 utility-scale energy storage platform, spotlighting ON’s role in high-efficiency grid storage technology.

For context, ON Semiconductor’s share price has climbed 10.66% over the past month but is still down 15.65% on a 3 month view. Its year to date share price return of 29.98% and 1 year total shareholder return of 40.30% suggest the recent Sungrow win is arriving as momentum rebuilds after a weaker spell.

ON Semiconductor now sits at US$73.70 after the Sungrow win and a sharp rebound. Does that recent strength still leave enough upside to justify the risks buyers take from here?

Most Popular Narrative: 29% Undervalued

ON Semiconductor’s most followed valuation story pegs fair value at $104.46, which is well above the last close at $73.70. That gap presents the Sungrow deal as one piece of a much broader power and AI grid thesis rather than a single isolated headline.

The company's investments in silicon carbide, vertical GaN and the Embedded Power Platform are now tied to a much larger AI data center opportunity, with management lifting its 2030 server and AI data center market estimate from about US$12b to nearly US$50b and targeting AI data center revenue growth at least 10 percentage points faster than the market, which could materially influence long term revenue and margin expansion.

See why 127 investors see ON Semiconductor as 29% undervalued.

Result: Fair Value of $104.46 (UNDERVALUED)

Still, the story for ON Semiconductor can change quickly if EV demand weakens further or if AI focused power products and the Synaptics deal fail to scale as planned.
