Semtech (SMTC): Reassessing Valuation After Solid Q3 Results and Record Data Center Growth

Simply Wall St

Semtech (SMTC) just delivered a quarter that largely did what investors wanted: steady execution, record data center sales, and clear guidance pointing to more growth ahead even as margins feel some mix pressure.

See our latest analysis for Semtech.

That narrative seems to be feeding into the stock’s momentum, with a roughly 22.6% 3 month share price return and a powerful 3 year total shareholder return of about 156%, even though the latest close is $73.46.

If Semtech’s trajectory has you thinking about what else might be building momentum in chips and connectivity, now could be a good time to explore high growth tech and AI stocks.

Yet with shares hovering just below analyst targets after a huge three year run, is Semtech still trading at a discount to its true earnings power, or is the market already pricing in the next leg of growth?

Most Popular Narrative Narrative: 8.4% Undervalued

With Semtech last closing at $73.46 against a narrative fair value of about $80.21, the story leans toward upside driven by earnings power and margins.

Analysts expect earnings to reach $253.1 million (and earnings per share of $2.05) by about September 2028, up from $23.8 million today.

In order for the above numbers to justify the analysts price target, the company would need to trade at a PE ratio of 35.8x on those 2028 earnings, down from 210.9x today. This future PE is greater than the current PE for the US Semiconductor industry at 30.1x.

Another Lens on Valuation

While the narrative fair value suggests Semtech is 8.4% undervalued, our DCF model points the other way. It puts fair value closer to $47.26. On that view, today’s $73.46 price bakes in a lot of growth already and leaves less room for error if margins slip.
