Semtech Corporation (NASDAQ:SMTC) saw its shares climb 4.3% in premarket trading on Wednesday, August 26, 2026, after the company issued third-quarter revenue guidance that significantly exceeded Wall Street expectations. The stock was priced at $133.00 at 06:30 EDT, up from Tuesday's closing price of $127.52, adding roughly $510 million to the company's implied market value. This follows a 5.5% gain during the regular session, bringing the total increase from Monday's close of $120.91 to 10.0%.
Strong Q3 Guidance
Semtech projects third-quarter revenue of $410 million, plus or minus $5 million, which is 13.9% above the consensus estimate of $359.9 million and 19.9% higher than the second-quarter revenue of $341.9 million. The company also guided adjusted earnings per share (EPS) to $1.05, give or take three cents, compared to the analyst consensus of 73 cents—a 43.8% beat at the midpoint.
This robust outlook reflects accelerating demand across key segments, particularly data-center solutions, which hit a record $100 million in revenue during the second quarter, up 91% year-over-year and accounting for 29.2% of total sales. Infrastructure revenue also surged 69% to $124 million, while sales of LoRa-enabled products grew 58% to $58 million. IoT Systems and Connectivity revenue rose 11% to $98.3 million, and semiconductor product sales climbed 44% to $243.5 million.
Record Q2 Results
For the second quarter, Semtech reported revenue of $341.9 million, an all-time high, representing a 33% increase year-over-year and a 17% sequential rise. Adjusted earnings jumped 73% to 71 cents per share, beating the consensus of 61 cents by 16.4%. Adjusted gross margin expanded to 54.5% from 53.2% a year ago, while adjusted operating margin improved by 560 basis points to 24.4%.
The company's margin profile is expected to strengthen further, with third-quarter gross margin guidance of 58.3%. This improvement is partly attributed to the divestiture of its cellular-module unit, which was sold for $62 million. The segment, now classified as held-for-sale, generated $48.1 million in revenue and $10.9 million in adjusted gross profit during the quarter, translating to a margin of just 22.7%—significantly lower than the rest of Semtech's operations. Removing this low-margin business should boost overall profitability.
Cash Flow and Backlog
Free cash flow climbed 48% to $61.4 million, more than doubling from the prior quarter. CEO Hong Hou highlighted that growing bookings and an all-time high backlog signal "a strong inflection in growth," providing confidence in the company's ability to convert its record order book into revenue.
Analysts remain bullish on Semtech, with a Strong Buy consensus. Among fifteen analysts, twelve rate it Strong Buy, one assigns Buy, and two issue Hold ratings. The average price target stands at $202.92, ranging from $155 to $230, implying significant upside from current levels.
Risks and Outlook
Despite the positive momentum, there are risks. Premarket prices can be volatile and may reverse during less liquid trading. The outlook depends on timely data-center demand and the conversion of bookings into shipments. Margin growth could face challenges from supply constraints, reliance on key customers, and the successful completion of divestitures.
The market's reaction underscores the significance of Semtech's guidance, but the company now faces the task of delivering on its 14% revenue beat. Its record backlog offers proof for investors while also raising expectations for sustained growth in the coming quarters.
