Assessing ON Semiconductor (ON) Valuation Following Subtle Share Price Uptick

Simply Wall St
It’s easy to see why ON Semiconductor (ON) might be catching your eye right now. The company’s share price just edged up slightly, closing at $50.16, a move that comes after a period of mild turbulence for the broader chip sector. There’s no headline-grabbing event behind this latest tick higher. Subtle shifts like these often raise the question for investors: does a small uptick actually mean something, or is it just noise in a volatile sector? Looking at the bigger picture, ON Semiconductor’s share price has had a rough time over the past year, with the stock down over 32%. The past month alone has seen a modest pullback, reinforcing a downward trend that stands in contrast to its strong five-year surge of more than 120%. Despite this recent weakness, the company is still showing solid annual revenue and dramatic net income growth. This adds another layer for those weighing fundamentals against market momentum. So is the current pullback offering up a genuine bargain, or is the market already factoring in all the company’s future potential? Let’s take a closer look at the numbers and see what the valuation really tells us.

Most Popular Narrative: 12.8% Undervalued

According to the most widely followed narrative, ON Semiconductor is currently undervalued by over 12% compared to its estimated fair value.

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.

Curious what powers such a bullish view? The path to this fair value is paved with forward-looking financial bets and bold margin expansion targets. If you want the inside scoop on which future profits and revenue changes could push the stock much higher, the full narrative is where all the numbers come to life.

Result: Fair Value of $57.53 (UNDERVALUED)

However, persistent manufacturing underutilization and heightened competition, especially in fast-evolving EV and AI markets, could disrupt ON Semiconductor’s path to margin growth.

While the previous fair value estimate points to upside, checking the market’s favored comparison method—price-to-earnings versus the industry average—tells a less optimistic story. On this yardstick, ON looks expensive. Does the market know something we don’t, or is this just a mismatch between growth and value?
