Same Industry, Less Money: What First Solar and NVIDIA Offer That ON Semiconductor Does Not

Same Industry, Less Money: What First Solar and NVIDIA Offer That ON Semiconductor Does Not

When a rival is growing faster and costs less than half as much per dollar of profit, an investor has to ask what exactly they are paying a premium for.

For an investor in ON Semiconductor (ON), the question is direct: what exactly is the extra money buying? In the same industry, First Solar (FSLR) is growing faster, and the market charges less than half as much for each dollar of its operating profit. This isn't a new development. The valuation gap between the two has held roughly steady for the past year, suggesting the market has its reasons for pricing ON at a significant premium. The task is to weigh those reasons against the numbers on the table.

ON's premium is the price of a strategic pivot into higher-margin markets.

The case for ON Semiconductor's valuation rests on its future, not its recent past. The company is executing a deliberate shift away from lower-margin products and toward high-growth, high-value applications in automotive and artificial intelligence. Management points to its AI data center business, where revenue grew more than 30% in a single quarter and is now expected to double year over year in 2026. This is the kind of targeted growth that can command a premium.

This pivot is designed to drive profitability. New product platforms targeting automotive and AI applications are expected to carry gross margins in the 60% to 70% range. That's a significant step up from the company's current profile. In automotive, ON is embedding itself in the electric vehicle transition, supplying silicon carbide for next-generation 900-volt EV platforms with partners like Geely and NIO. The company's technology was in approximately 55% of new EV models shown at a recent auto show. The argument is that today's multiple is buying a stake in a more profitable, faster-growing company that is still taking shape.

The key numbers side by side, today:

OpInc = Operating Income, P/OpInc = Price To Operating Income Ratio

And the same comparison exactly a year ago, so you can see which way the mismatch has been moving:

OpInc = Operating Income, P/OpInc = Price To Operating Income Ratio

Paying up for ON means forgoing demonstrated growth and profitability.

The cost of that premium is clear when looking at the alternative. Beyond its lower valuation, First Solar is delivering the kind of results ON is still building toward. FSLR grew its revenue 27.3% over the last twelve months, while ON's revenue declined by 9.0%. The peer also operates more profitably today, with an operating margin of 31.8% compared to 17.5% for ON. The market is asking investors to pay more for a business that is currently smaller, slower, and less profitable.

While ON's AI segment is accelerating, its much larger automotive business is still waiting for a broad cyclical turn. Management noted on its recent earnings call that the "automotive market has not seen a recovery yet." This highlights the risk: an investor is paying a premium for a transformation story that depends heavily on end markets that are not yet firing on all cylinders. For those who prefer broader exposure to the industry without picking a single name, a semiconductor ETF like SOXX offers another path.

The choice turns on whether AI revenue can outrun the auto cycle.

Ultimately, ON's premium valuation is a bet that its strategic pivot into high-value AI and electric vehicles will redefine its earnings power, justifying the price over peers with stronger current results. The wager on future potential stands in contrast to the proven, high-speed growth available elsewhere today.

The most direct test of this strategy is the company's AI business. Management has set a clear benchmark, stating they "expect our AI data center revenue to double year over year in 2026." The company's progress toward that specific target is the key signal to watch.

Paying The Right Price For Growth Is The Whole Game

This comparison is one instance of the only question that matters in stock picking: how much growth are you getting per dollar you pay? Most portfolios never ask it systematically, which is why most portfolios trail.

The Trefis High Quality (HQ) Portfolio is that question turned into a machine: roughly 30 businesses screened for real growth at defensible prices, held with discipline. It has a track record of outpacing a benchmark that combines all major indices - the S&P 500, S&P Mid-cap, and Russell 2000.
