Why We Think Semtech Will Underperform
A public company since the late 1960s, Semtech (NASDAQ:SMTC) is a provider of analog and mixed-signal semiconductors used for Internet of Things systems and cloud connectivity.
- Negative returns on capital show that some of its growth strategies have backfired
- Performance over the past five years shows its incremental sales were less profitable as its earnings per share were flat
- One positive is that its sales outlook for the upcoming 12 months calls for 47.8% growth, an acceleration from its two-year trend
Why There Are Better Opportunities Than Semtech
Why There Are Better Opportunities Than Semtech
Semtech is trading at $150.27 per share, or 29.8x forward P/E. This multiple is quite expensive for the quality you get.
Paying a premium for high-quality companies with strong long-term earnings potential is preferable to owning challenged businesses with questionable prospects. That helps the prudent investor sleep well at night.

Company Overview
Semtech was founded in 1960 by Gustav H.D. Franzen and Harvey Stump, Jr. The two initially started Semtech to provide components for companies with aerospace and military contracts. The company went public in 1967.
Semtech is a pioneer and leader in LoRa (long range) technology for radio communication, which has become the de facto wireless platform of Internet of Things. LoRa encodes information on radio waves using chirp pulses, making its transmission robust against disturbances over longer distances and superior over WiFi and Bluetooth. LoRa is also well-suited for applications that transmit small chunks of data with low bit rate, making it ideal for the sensors that operate in low power mode found in IoT applications.
In addition, Semtech offers a portfolio of signal integrity products for optical data communications and video transport. The companyâs signal integrity chips can be found in wireless base stations that enable cellular communications and high-definition broadcasts that enable television technologies.
Semtechâs customers include major OEMs and their subcontractors in the infrastructure, consumer, and industrial end markets. Semtech outsources the majority of manufacturing functions to third-party foundries and assembly contractors.
Competitors offering analog and mixed-signal semiconductors for infrastructure and communications include Cisco (NASDAQ:CSCO), KORE Group (NYSE:KORE), and NXP Semiconductors (NASDAQ:NXPI).
4. Revenue Growth
A companyâs long-term sales performance is one signal of its overall quality. Any business can put up a good quarter or two, but many enduring ones grow for years. Over the last five years, Semtech grew its sales at a solid 11.7% compounded annual growth rate. Its growth beat the average semiconductor company and shows its offerings resonate with customers. Semiconductors are a cyclical industry, and long-term investors should be prepared for periods of high growth followed by periods of revenue contractions.
We at StockStory place the most emphasis on long-term growth, but within semiconductors, a half-decade historical view may miss new demand cycles or industry trends like AI. Semtechâs annualized revenue growth of 20% over the last two years is above its five-year trend, suggesting its demand was strong and recently accelerated.
This quarter, Semtech reported wonderful year-on-year revenue growth of 32.7%, and its $341.9 million of revenue exceeded Wall Streetâs estimates by 4%. Beyond the beat, this marks 8 straight quarters of growth, showing that the current upcycle has had a good run - a typical upcycle usually lasts 8-10 quarters. Company management is currently guiding for a 53.6% year-on-year increase in sales next quarter.
Looking further ahead, sell-side analysts expect revenue to grow 30.4% over the next 12 months. While this projection indicates its newer products and services will catalyze better top-line performance, it is still below the sector average.
5. Product Demand & Outstanding Inventory
Days Inventory Outstanding (DIO) is an important metric for chipmakers, as it reflects a businessâs capital intensity and the cyclical nature of semiconductor supply and demand. In a tight supply environment, inventories tend to be stable, allowing chipmakers to exert pricing power. Steadily increasing DIO can be a warning sign that demand is weak, and if inventories continue to rise, the company may have to downsize production.
This quarter, Semtechâs DIO came in at 98, which is 54 days below its five-year average. At the moment, these numbers show no indication of an excessive inventory buildup.
6. Gross Margin & Pricing Power
Gross profit margin is a key metric to track because it shows how much money a semiconductor company gets to keep after paying for its raw materials, manufacturing, and other input costs.
Semtechâs unit economics are roughly in line with other semiconductor businesses, pointing to a lack of significant pricing pressure and the effectiveness of its products. As you can see below, it averaged a decent 52.7% gross margin over the last two years. That means for every $100 in revenue, roughly $52.72 was left to spend on selling, marketing, R&D, and general administrative overhead.
In Q2, Semtech produced a 53.8% gross profit margin, in line with the same quarter last year. Zooming out, the companyâs full-year margin has remained steady over the past 12 months, suggesting its input costs (such as raw materials and manufacturing expenses) have been stable and it isnât under pressure to lower prices.
7. Operating Margin
Operating margin is one of the best measures of profitability because it tells us how much money a company takes home after procuring and manufacturing its products, marketing and selling those products, and most importantly, keeping them relevant through research and development.
Semtech was profitable over the last two years but held back by its large cost base. Its average operating margin of 7.1% was weak for a semiconductor business.
Analyzing the trend in its profitability, Semtechâs operating margin decreased by 16 percentage points over the last five years. This raises questions about the companyâs expense base because its revenue growth should have given it leverage on its fixed costs, resulting in better economies of scale and profitability. Semtechâs performance was poor no matter how you look at it - it shows that costs were rising and it couldnât pass them onto its customers.
In Q2, Semtech generated an operating margin profit margin of 16.3%, up 22.6 percentage points year on year. The increase was solid, and because its operating margin rose more than its gross margin, we can infer it was more efficient with expenses such as marketing, R&D, and administrative overhead.
8. Earnings Per Share
Revenue trends explain a companyâs historical growth, but the long-term change in earnings per share (EPS) points to the profitability of that growth â for example, a company could inflate its sales through excessive spending on advertising and promotions.
Semtechâs flat EPS over the last five years was below its 11.7% annualized revenue growth. This tells us the company became less profitable on a per-share basis as it expanded.
Diving into the nuances of Semtechâs earnings can give us a better understanding of its performance. As we mentioned earlier, Semtechâs operating margin expanded this quarter but declined by 16 percentage points over the last five years. Its share count also grew by 53.7%, meaning the company not only became less efficient with its operating expenses but also diluted its shareholders.
In Q2, Semtech reported adjusted EPS of $0.71, up from $0.41 in the same quarter last year. This print easily cleared analystsâ estimates, and shareholders should be content with the results. Over the next 12 months, Wall Street expects Semtechâs full-year EPS to grow 54.6% from $2.14 to $3.31.
9. Cash Is King
Although earnings are undoubtedly valuable for assessing company performance, we believe cash is king because you canât use accounting profits to pay the bills.
Semtech has shown weak cash profitability relative to peers over the last two years, giving the company fewer opportunities to return capital to shareholders. Its free cash flow margin averaged 14.2%, below what weâd expect for a semiconductor business.
Taking a step back, we can see that Semtechâs margin dropped by 9 percentage points over the last five years. This along with its unexciting margin puts the company in a tough spot, and shareholders are likely hoping it can reverse course. If the trend continues, it could signal itâs in the middle of a big investment cycle.
10. Return on Invested Capital (ROIC)
EPS and free cash flow tell us whether a company was profitable while growing its revenue. But was it capital-efficient? A companyâs ROIC explains this by showing how much operating profit it makes compared to the money it has raised (debt and equity).
Semtechâs five-year average ROIC was negative 6.1%, meaning management lost money while trying to expand the business. Its returns were among the worst in the semiconductor sector.
11. Balance Sheet Assessment
Semtech reported $204.1 million of cash and $492.8 million of debt on its balance sheet in the most recent quarter. As investors in high-quality companies, we primarily focus on two things: 1) that a companyâs debt level isnât too high and 2) that its interest payments are not excessively burdening the business.
With $277.6 million of EBITDA over the last 12 months, we view Semtechâs 1.0Ã net-debt-to-EBITDA ratio as safe. We also see its $27.05 million of annual interest expenses as appropriate. The companyâs profits give it plenty of breathing room, allowing it to continue investing in growth initiatives.
12. Key Takeaways from Semtechâs Q2 Results
We were impressed by Semtechâs strong improvement in inventory levels. We were also glad its EPS outperformed Wall Streetâs estimates. Zooming out, we think this quarter featured some important positives. The stock traded up 3.6% to $132.07 immediately following the results.
13. Is Now The Time To Buy Semtech?
Updated: September 15, 2026 at 10:33 PM EDT
Are you wondering whether to buy Semtech or pass? We urge investors to not only consider the latest earnings results but also longer-term business quality and valuation.
Semtech isnât a terrible business, but it isnât one of our picks. Although its revenue growth was solid over the last five years and is expected to accelerate over the next 12 months, its relatively low ROIC suggests management has struggled to find compelling investment opportunities. And while the companyâs projected EPS for the next year implies the companyâs fundamentals will improve, the downside is its cash profitability fell over the last five years.
Semtechâs P/E ratio based on the next 12 months is 29.8x. Investors with a higher risk tolerance might like the company, but we donât really see a big opportunity at the moment. Weâre fairly confident there are better investments elsewhere.
Wall Street analysts have a consensus one-year price target of $209.29 on the company (compared to the current share price of $150.27).
Although the price target is bullish, readers should exercise caution because analysts tend to be overly optimistic. The firms they work for, often big banks, have relationships with companies that extend into fundraising, M&A advisory, and other rewarding business lines. As a result, they typically hesitate to say bad things for fear they will lose out. We at StockStory do not suffer from such conflicts of interest, so weâll always tell it like it is.
