Approach 1: Littelfuse Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow, or DCF, model estimates what a stock could be worth by projecting its future cash flows and discounting them back to today, using a required return to reflect risk and the time value of money.

For Littelfuse, the model uses a 2 Stage Free Cash Flow to Equity approach based on cash flow projections. The latest twelve month Free Cash Flow is about $370.5 million. Analyst estimates extend out to 2028, then Simply Wall St extrapolates further, with projected Free Cash Flow of $690.0 million in 2030 and continued projections through 2035, all expressed in dollars and discounted back to today.

Putting these forecast and extrapolated cash flows together, the DCF model arrives at an estimated intrinsic value of about $458.14 per share. Compared with a current share price around $441, this implies the stock trades at roughly a 3.7% discount to this DCF estimate, which is a small gap rather than a clear bargain or clear premium.

Result: ABOUT RIGHT

Littelfuse is fairly valued according to our Discounted Cash Flow (DCF), but this can change at a moment's notice. Track the value in your watchlist or portfolio and be alerted on when to act.

Approach 2: Littelfuse Price vs Sales

For profitable companies that already generate meaningful revenue, the P/S ratio can be a useful way to gauge how much investors are paying for each dollar of sales, especially when earnings are affected by accounting items or short term swings.

What counts as a "normal" P/S often reflects what investors expect for future growth and how risky those expectations appear. Higher expected growth or lower perceived risk can justify a higher multiple, while slower growth or higher uncertainty usually calls for a lower one.

Littelfuse currently trades on a P/S of 4.48x, compared with an Electronic industry average of 2.58x and a peer average of 3.07x. Simply Wall St’s Fair Ratio for Littelfuse is 3.26x. This is a proprietary estimate of the P/S level that might make sense given factors such as its earnings growth profile, profit margins, industry, market cap and specific risks.

The Fair Ratio can be more informative than a simple peer or industry comparison because it adjusts for those company specific drivers rather than assuming all stocks in the group deserve similar pricing. With the current 4.48x P/S sitting above the 3.26x Fair Ratio, the shares appear overvalued on this measure.

Result: OVERVALUED

Upgrade Your Decision Making: Choose your Littelfuse Narrative

Earlier the article mentioned that there is an even better way to understand valuation. Narratives are introduced here as a simple way for you to attach a clear story to your numbers, linking how you see Littelfuse’s future revenue, earnings and margins to a Fair Value estimate that can be compared with today’s share price to help decide whether it looks attractive or stretched.

On Simply Wall St’s Community page, Narratives let you set out that story in an accessible format used by millions of investors. They then automatically tie it to a forecast and valuation that update as new earnings, news or guidance comes in, so your view does not stay frozen while the company and market move.

For Littelfuse, one investor might build a Narrative close to the more optimistic analyst cohort, anchoring on a Fair Value around US$520 that reflects assumptions such as earnings of about US$502.2 million and a P/E of 33.1x by 2029. Another might lean toward the cautious end with a Fair Value closer to US$320 based on earnings nearer US$424.5 million and a P/E of 25.5x. Comparing either Narrative’s Fair Value to the current price is what turns that story into a practical decision tool.

For Littelfuse however we will make it really easy for you with previews of two leading Littelfuse Narratives:

Each one connects a clear story about revenue, earnings and risks to a Fair Value anchor you can compare with the current share price around US$441.

Fair Value: US$475 per share

Implied pricing gap vs current price: around 7.1% below this Fair Value, so the stock is trading at a small discount to this narrative.

Revenue growth assumption: about 10.28% a year

• Focuses on electrification, renewable energy and data center demand as key drivers that could support higher revenue and margin outcomes than the market currently prices in.
• Highlights operational efficiency work, a move toward more complete solutions and a solid balance sheet as reasons earnings could scale if execution stays on track.
• Flags real risks around power semiconductor softness, cyclical end markets and competition, and encourages you to test whether the assumed 2029 earnings and 33.1x P/E feel reasonable for you.

Fair Value: US$320 per share

Implied pricing gap vs current price: around 37.9% above this Fair Value, so the stock is trading at a clear premium to this narrative.

Revenue growth assumption: about 9.19% a year

• Starts from the view that AI and defense optimism, plus enthusiasm around smart electrical solutions, may already be well reflected in the share price.
• Builds in solid earnings improvement but applies a lower 25.5x P/E, reflecting concerns that tariffs, trade shifts and softer demand in areas like passenger cars could weigh on margins.
• Points to ongoing macro and execution risks around acquisitions and profit sustainability, and treats a US$320 Fair Value as more consistent with cautious expectations.

Putting these side by side gives you a quick valuation range around roughly US$320 to US$475 that is grounded in specific revenue, margin and P/E assumptions, rather than just a single target.
