Littelfuse (LFUS): Revisiting Valuation After Steady Share Gains and Undervalued Narrative Signals

Simply Wall St

Recent share performance and setup

Littelfuse (LFUS) has quietly outperformed many industrial tech peers this year, with the stock up about 9% year to date and roughly 10% over the past year, despite some recent pullback.

See our latest analysis for Littelfuse.

The recent pullback after a solid 1 month share price return suggests some short term profit taking, but the 1 year total shareholder return still points to steady, if unspectacular, momentum.

If you are comparing Littelfuse to what else is working in the market, this could be a good moment to explore high growth tech and AI stocks for other tech names with similar tailwinds.

With steady fundamentals, mid single digit sales growth, and the shares still trading at a discount to analyst targets, the key question now is whether Littelfuse is an undervalued compounder or if the market is already pricing in its next leg of growth.

Most Popular Narrative Narrative: 17.1% Undervalued

With Littelfuse closing at $255 versus a most popular narrative fair value of $307.50, the valuation gap sets the stage for some ambitious growth 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.

Curious what kind of revenue runway, margin lift, and future earnings multiple are baked into that price gap? The narrative spells out a surprisingly aggressive profitability path, calibrated to long term electrification demand, that you might want to stress test for yourself.

Result: Fair Value of $307.50 (UNDERVALUED)

However, lingering execution risks in power semiconductors, along with heavy exposure to cyclical auto and industrial demand, could quickly challenge that upbeat profitability trajectory.

Another angle on valuation

While the narrative and fair value work point to Littelfuse as undervalued, its current price to earnings ratio of 53.5 times looks stretched versus the US Electronic industry at 24.5 times, peers at 39.4 times, and a fair ratio of 29 times. This raises the risk of multiple compression if growth disappoints.
