Heavy Reliance On AI Data Centers Will Limit Long-Term Upside

Catalysts

About Semtech

Semtech supplies analog and mixed signal semiconductors and IoT systems used in data centers, communications, industrial IoT and sensing applications.

What are the underlying business or industry changes driving this perspective?

• Heavy dependence on hyperscaler AI data center spending leaves Semtech exposed if large customers slow network upgrades. This could weigh on data center net sales and limit earnings growth.
• Plans to ramp Linear Pluggable Optics and active copper cable solutions into high volume rely on ongoing transitions to 800G and 1.6T architectures. Any delay in optics or switch rollouts could pressure revenue and keep adjusted operating margins from improving.
• LoRa and broader IoT connectivity demand is tied to expanding smart infrastructure and 5G adoption. Slower project rollouts or tighter customer budgets could soften LoRa enabled solutions net sales and restrain consolidated gross margin given their above average contribution.
• The IoT Systems and Connectivity business depends on continued growth in 4G and 5G cellular modules. These products carry gross margins considerably below the corporate average, which could cap adjusted gross margin and EBITDA margin even if top line continues to rise.
• Incremental R&D spending on data center and the newly acquired force sensing portfolio increases fixed costs. If expected design wins in wearables, smartphones and automotive are slower than anticipated, adjusted operating expenses could rise faster than revenue growth and compress net margins.

Assumptions

How have these above catalysts been quantified?

• This narrative explores a more pessimistic perspective on Semtech compared to the consensus, based on a Fair Value that aligns with the bearish cohort of analysts.
• The bearish analysts are assuming Semtech's revenue will grow by 22.2% annually over the next 3 years.
• The bearish analysts assume that profit margins will increase from -3.0% today to 20.0% in 3 years time.
• The bearish analysts expect earnings to reach $398.3 million (and earnings per share of $3.94) by about August 2029, up from -$33.2 million today. However, there is some disagreement amongst the analysts with the more bullish ones expecting earnings as high as $614.5 million.
• In order for the above numbers to justify the price target of the more bearish analyst cohort, the company would need to trade at a PE ratio of 63.7x on those 2029 earnings, up from -348.6x today. This future PE is greater than the current PE for the US Semiconductor industry at 47.7x.
• The bearish analysts expect the number of shares outstanding to grow by 7.0% per year for the next 3 years.
• To value all of this in today's terms, we will use a discount rate of 11.42%, as per the Simply Wall St company report.

Risks

What could happen that would invalidate this narrative?

• Data center products such as FiberEdge TIAs, CopperEdge equalizers, LPO drivers and ACC solutions are already generating record net sales, with Q3 data center revenue at US$56.2 million and customer forecasts extending through 2026, which could support higher long-term revenue and earnings than a bearish view assumes.
• LoRa enabled solutions recorded Q3 net sales of US$40 million with 40% year over year growth and Gen 4 LoRa Plus multiprotocol chips are opening up new use cases like higher data rate drones and richer sensor applications, which could support stronger long-term revenue and potentially higher gross margin given LoRa’s above average contribution.
• The IoT Systems and Connectivity business has completed certifications for 5G RedCap modules, is seeing a strong pipeline and double digit growth in mission critical cellular router markets, which may support sustained top line growth even if cellular modules weigh on segment gross margin.
• The acquisition of Qorvo’s force sensing business, combined with Semtech’s existing capacitive sensing and PerSe portfolio, expands the sensor offering into computing, smartphones, wearables and automotive, which could lead to incremental revenue and support net margin if cross selling into existing customers scales.
• Materially lower annual interest expense, from about US$75 million a year ago to under US$3 million now, together with rising operating cash flow and lower net leverage of 1.5x, gives the company more room to invest in R&D for its core assets, which could support higher long-term earnings and cash generation than a bearish share price view implies.

Valuation

How have all the factors above been brought together to estimate a fair value?

• The assumed bearish price target for Semtech is $160.74, which represents up to two standard deviations below the consensus price target of $201.38. This valuation is based on what can be assumed as the expectations of Semtech's future earnings growth, profit margins and other risk factors from analysts on the more bearish end of the spectrum.
• However, there is a degree of disagreement amongst analysts, with the most bullish reporting a price target of $230.0, and the most bearish reporting a price target of just $155.0.
• In order for you to agree with the more bearish analyst cohort, you'd need to believe that by 2029, revenues will be $2.0 billion, earnings will come to $398.3 million, and it would be trading on a PE ratio of 63.7x, assuming you use a discount rate of 11.4%.
• Given the current share price of $124.09, the analyst price target of $160.74 is 22.8% higher.
• We always encourage you to reach your own conclusions though. So sense check these analyst numbers against your own assumptions and expectations based on your understanding of the business and what you believe is probable.
