• If you are wondering whether Semtech's share price still reflects good value after a strong run, it helps to step back and look at what the current valuation is really pricing in.
• The stock last closed at US$103.48, with returns of 14.8% over 7 days, 40.6% over 30 days, 37.5% year to date and 319.1% over the past year. Any view on value now needs to factor in that kind of move.
• Recent news coverage has focused on Semtech's position within the broader semiconductor space and how investors are reacting to its role in areas like connectivity and data infrastructure. This context has helped shape sentiment around the stock at its current price level.
• Semtech currently has a value score of 1 out of 6. The next step is to compare what different valuation methods suggest about the share price today, followed by a more holistic way to think about valuation that goes beyond a single model.

Semtech scores just 1/6 on our valuation checks. See what other red flags we found in the full valuation breakdown.

Approach 1: Semtech Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow, or DCF, model takes estimates of the cash a company may generate in the future and discounts those amounts back to today, to arrive at an estimate of what the business could be worth now.

For Semtech, the model used is a 2 Stage Free Cash Flow to Equity approach, based on cash flow projections in US$. The latest twelve month free cash flow is US$158.4 million. Analysts provide explicit free cash flow estimates out to 2029, with US$314.6 million projected for that year. Further figures out to 2035 are extrapolated by Simply Wall St rather than coming directly from analyst forecasts.

After discounting all these projected cash flows, the DCF model arrives at an estimated intrinsic value of US$44.91 per share. Against the recent share price of US$103.48, this DCF implies the stock is 130.4% overvalued on this set of assumptions.

Result: OVERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Semtech may be overvalued by 130.4%. Discover 58 high quality undervalued stocks or create your own screener to find better value opportunities.

Approach 2: Semtech Price vs Sales

For companies where earnings can be volatile, the P/S ratio is often a useful cross check because it focuses on revenue rather than profit, which can be affected by accounting items or short term swings in margins.

In general, higher growth expectations and lower perceived risk tend to justify a higher P/S multiple. Slower growth prospects or higher risk usually align with a lower, more conservative P/S range. So context around the business and its sector matters a lot when you look at this metric.

Semtech currently trades on a P/S ratio of 9.16x. That sits above the broader Semiconductor industry average of 6.64x and below the peer group average of 17.17x. Simply Wall St's proprietary Fair Ratio for Semtech is 6.00x. This Fair Ratio is designed to reflect the P/S multiple that might be reasonable for the company given factors such as its earnings growth profile, profit margins, industry, market cap and key risks.

Because the Fair Ratio blends these fundamentals, it can offer a more tailored reference point than a simple comparison with industry or peer averages. Against this 6.00x Fair Ratio, the current 9.16x P/S suggests the shares trade at a richer level than that model implies.

Result: OVERVALUED

Upgrade Your Decision Making: Choose your Semtech Narrative

Earlier it was mentioned that there is an even better way to understand valuation. Narratives on Simply Wall St give you a clear story behind the numbers by linking your view of Semtech’s future revenue, earnings and margins to a specific forecast and Fair Value. They update that view automatically when fresh data like news or earnings arrives and help you compare Fair Value with the current price to decide whether Semtech looks expensive or cheap based on your assumptions. Some investors on the Community page build a higher Fair Value narrative closer to US$115 that leans into AI data center and LoRa adoption, while others build a lower Fair Value narrative around US$74 that leans into execution and concentration risks, all using the same tool in slightly different ways.

For Semtech, however, we will make it really easy for you with previews of two leading Semtech narratives:

Fair Value: US$104.62

Implied pricing gap vs last close: about 1.1% premium to the narrative fair value

Revenue growth assumption: 12.41% a year

• Leans on AI driven data center and optical connectivity demand, with products like FiberEdge, CopperEdge and low power optics feeding into higher content per deployment.
• Sees LoRa and broader IoT adoption as expanding Semtech's addressable market and supporting recurring, higher margin revenue from IP and licensing.
• Assumes portfolio focus, higher R&D spending and a better balance sheet help support margin recovery, higher earnings and justify analyst targets around US$104.62 to US$115.

Fair Value: US$74.00

Implied pricing gap vs last close: about 40% above the narrative fair value

Revenue growth assumption: 12.02% a year

• Highlights reliance on hyperscaler AI data center spending and optic upgrade cycles, which could leave revenue and margins exposed if rollouts slow or shift.
• Points out that lower margin IoT systems and connectivity products, along with higher R&D and operating costs, could cap gross margin and EBITDA margin even if sales rise.
• Frames a fair value of US$74 as closer to the bearish analyst cohort, with expectations that current pricing already bakes in optimistic assumptions on growth, mix and execution.
