Littelfuse (LFUS) Valuation Check After Strong Q3 Revenue Growth and Electronics Segment Outperformance

Littelfuse (LFUS) just delivered a third quarter that turned some heads, with revenue up roughly 10% year on year and the Electronics segment and adjusted operating income topping Wall Street’s expectations.

See our latest analysis for Littelfuse.

Investors have been warming back up to Littelfuse, with a 1 month share price return of 6.84% helping lift the year to date share price return to 10.59%. However, the 1 year total shareholder return sits at a more muted 3.45%, suggesting momentum is only now starting to rebuild after a softer stretch.

If this earnings beat has you thinking about where else growth and electrification trends could show up next, it is worth exploring aerospace and defense stocks as another hunting ground for ideas.

With shares up recently but still trading below analyst targets and our view of intrinsic value, is Littelfuse quietly offering a rare entry point in electrification, or is the market already pricing in its next leg of growth?

Most Popular Narrative Narrative: 15.6% Undervalued

With Littelfuse last closing at $259.55 against a fair value of $307.50 in the most followed narrative, the gap hinges on ambitious growth and margin assumptions.

The rapid buildout of renewable energy infrastructure, grid storage, and sustainable grid ecosystems is resulting in double digit sales growth and a robust opportunity pipeline for Littelfuse, positioning the company to benefit from continued secular tailwinds and expanding its addressable market, which should positively impact both revenues and margins.

Read the complete narrative.

Curious how steady mid single digit top line growth could still support a much larger earnings base and lower future multiple than today? The narrative leans on compounding margin gains and a powerful earnings ramp that might surprise anyone only glancing at headline forecasts. Want to see exactly how those moving pieces add up to this fair value call?

Result: Fair Value of $307.50 (UNDERVALUED)

However, slower progress in power semiconductors or a sharper downturn in auto and industrial demand could quickly challenge the upbeat long term earnings narrative.

Another View: Rich Multiple, Higher Bar

Step back from narratives and the picture looks tougher. Littelfuse trades on a lofty 54.5x earnings versus 24.6x for the US Electronic industry and a 29.1x fair ratio. This means any stumble could hit the share price hard. Is this premium really worth paying?
