That backdrop helps explain why, despite a weak year to date with a negative share price return and a one year total shareholder return of about negative 16 percent, the recent 1 month share price return near 20 percent suggests momentum may be rebuilding as investors reassess ON’s growth story.

If this GaN deal has you thinking about where the next winners might come from, it is a good time to explore high growth tech and AI names through high growth tech and AI stocks.

Yet with earnings under pressure, mixed long term returns, and the stock now sitting only modestly below analyst targets, is ON still flying under the radar, or is the market already pricing in its next leg of growth?

Most Popular Narrative Narrative: 5.9% Undervalued

With ON Semiconductor last closing at $55.21 versus a narrative fair value near $58.70, the story frames current pricing as leaving some upside on the table.

Structural improvements in manufacturing efficiency, including the Fab Right initiative and selective capacity reduction, are lowering operational costs and setting up significant margin expansion as utilization rates recover with end market demand. This operational leverage is likely to drive higher net margins and cash flow conversion as the cycle turns.
