A Fresh Look at ON Semiconductor's Valuation After New U.S. Tariff Plans Announced

Kshitija Bhandaru

ON Semiconductor (ON) just found itself at the center of the headlines, thanks to President Donald Trump’s announcement of substantial new tariffs on imported semiconductors. The twist is that companies with U.S.-based manufacturing or plans to invest domestically are exempt. This carve-out brings ON Semiconductor’s operational model sharply into focus. For investors, this is more than just a policy update as it raises immediate questions about ON’s cost structure and future pricing power if these tariffs become reality.

The stock has already been through a volatile run this year. After a tough twelve months that saw shares fall nearly 29%, ON Semiconductor has bounced by just over 3% in the past month. Major swings like these suggest the market is wrestling with shifting expectations, especially as the chip sector digests ongoing trade uncertainties and ON works to find its footing amid evolving global supply chains.

Given recent turbulence and this new policy blow, is ON Semiconductor now a bargain hiding in plain sight, or has the market already factored in all these future risks and rewards?

Most Popular Narrative: 14.8% Undervalued

According to the most widely followed narrative, ON Semiconductor is currently undervalued by nearly 15%. The valuation relies on major industry shifts and strategic positioning that analysts believe can drive future earnings and margins substantially higher.

"The company's strategic investments in silicon carbide (SiC), wide bandgap technologies, and advanced power management solutions for both automotive and AI data centers position it at the forefront of key structural growth markets. As these high-value products ramp, they are expected to enhance margins and drive long-term earnings growth."

What is fueling this optimistic outlook? There is a bold roadmap betting on stacked recurring revenues, significant increases in profits, and a future multiple that suggests premium status among peers. Want to see which standout assumptions about ON’s financial trajectory justify that striking fair value? The narrative’s summary is packed with projections that are drawing a lot of attention.

Result: Fair Value of $57.67 (UNDERVALUED)
