Introduction & Market Context
Semtech Corporation (NASDAQ:SMTC) presented its fiscal second quarter 2027 results on August 25, 2026, showcasing record revenue and significant profitability improvements driven by strength in data center and LoRa products. The presentation revealed net sales of $342 million, up 33% year-over-year, marking the company’s tenth consecutive quarter of revenue growth. Adjusted diluted earnings per share reached $0.71, representing 73% year-over-year growth and demonstrating strong operating leverage.

Quarterly Performance Highlights
As shown in the following summary of Q2’27 results, Semtech delivered broad-based performance improvements across key financial metrics.
The quarter’s performance was anchored by two primary growth drivers: data center products and LoRa-enabled solutions. Data center net sales reached a record $100 million, up 39% sequentially and 91% year-over-year, driven by continued strength in 800G products and the early ramp of 1.6T technology. LoRa-enabled net sales also hit a record $58 million, growing 31% quarter-over-quarter and 58% year-over-year.
President and CEO Hong Hou emphasized the company’s position "at the center of one of the most significant infrastructure build-outs in history," highlighting record revenue, earnings leverage, and significant progress on portfolio optimization. Management also noted accelerating bookings and record backlog providing visibility extending into fiscal year 2028.
The company’s financial performance demonstrated strong operating leverage, with adjusted diluted EPS growing at more than twice the rate of net sales growth, indicating improved cost management and favorable product mix shifts.
Segment Analysis
The following breakdown illustrates Semtech’s performance across its Infrastructure end market, which delivered exceptional growth in the quarter.
The Infrastructure segment, encompassing data center, PON/FTTH, wireless, and circuit protection products, generated $124 million in net sales, up 25% sequentially and 69% year-over-year. Within this segment, data center products stood out with record sales of $100 million, benefiting from strong demand for FiberEdge TIA and driver solutions. The company reported deepening engagement across all leading hyperscalers and design wins at every major module provider in target markets.
Management highlighted that FiberEdge at 1.6T is expected to exceed 50% market share by the end of fiscal 2027, while CopperEdge technology up to 1.6T is ready for volume deployment and currently in the design-in phase at all bandwidths up to 3.2T. The company’s photonics portfolio, spanning gain chips, high-power CW lasers, SOAs, and high-speed photodiodes, positions Semtech for content growth per transceiver from high single-digit to high double-digit dollars as the industry transitions from 800G to 3.2T.
The following chart shows performance in the Industrial end market, where LoRa products demonstrated significant momentum.
The Industrial segment generated $179 million in net sales, up 16% sequentially and 25% year-over-year. Record LoRa-enabled sales of $58 million reflected expansion across Smart Utilities, Smart Building, Smart City, and asset management applications. The company’s LoRa Gen 4 platform offers dual-band capability, expands data throughput to 2.6 Mbps, and provides multi-protocol flexibility while maintaining ultra-low power consumption.
Management noted that LoRaWAN is expanding into new use cases including predictive maintenance and public safety, while Amazon Sidewalk is gaining traction following Ring’s U.S. sensor launch and international expansion to Canada, Mexico, Europe, Australia, and Japan. The three pillars of LoRaWAN, LoRa Plus, and Amazon Sidewalk continue to reinforce each other, driving sustained growth momentum.
IoT Systems and Connectivity contributed $98 million in Q2’27 net sales, up 11% both sequentially and year-over-year, with RX400/EX400 5G RedCap routers moving into full-scale production.

Forward-Looking Statements
Semtech provided aggressive guidance for fiscal Q3’27, as illustrated in the following outlook summary.
The company projects Q3’27 net sales of $410 million (plus or minus $5 million), representing 54% year-over-year growth and 20% sequential growth. This outlook reflects continued momentum across all three major end markets, with particularly strong contributions expected from data center and LoRa products.
Management guided adjusted gross margin to 58.3% (plus or minus 100 basis points), representing a 380 basis point sequential improvement and 530 basis point year-over-year gain. Excluding the business held for sale, adjusted gross margin is projected at 63.9%, demonstrating the impact of portfolio optimization efforts.

By end market, management expects Infrastructure segment growth driven by data center revenue increasing 45% sequentially and 160% year-over-year, reflecting both 800G strength and meaningful 1.6T contributions. Industrial segment growth is anticipated with LoRa net sales rising approximately 15% sequentially and 65% year-over-year. The High-End Consumer segment is expected to benefit from seasonal trends and market share gains in TVS products.
Strategic Initiatives
The following slide outlines Semtech’s key priorities for fiscal year 2027, focusing on capacity expansion, R&D investment, and portfolio optimization.
Semtech highlighted three core strategic priorities for fiscal 2027. First, the company is actively securing incremental capacity for fiscal 2028 and beyond to support unprecedented growth. Management noted successful execution of capacity expansion plans, securing equipment deliveries for the current fiscal year and acquiring additional cleanroom space.
Second, the company is intensifying R&D investment to support customer technology roadmaps and add new growth drivers. Specific focus areas include solution offerings for lasers, photodiodes, drivers, and TIAs for Coherent Lite, XPO, NPO, and CPO applications. This investment aims to maintain Semtech’s technology leadership as the industry transitions to higher bandwidth requirements.
Third, Semtech continues portfolio optimization efforts, with management noting "more work ahead to continue reshaping Semtech." The company announced the divestiture of its cellular module business, which is expected to close in fiscal Q4’27. This transaction is projected to be EPS neutral on a non-GAAP basis while adding more than 500 basis points to gross margin, significantly improving the company’s profitability profile.
Management emphasized that the company is positioned for content growth per transceiver from high single-digit to high double-digit dollars as the industry transitions from 800G to 3.2T, representing a substantial long-term revenue opportunity. With 800G market leadership anchoring near-term growth and 1.6T inflection building, Semtech appears well-positioned to capitalize on the ongoing data center infrastructure buildout driven by artificial intelligence and cloud computing demand.
The record backlog and accelerating bookings provide visibility extending well into fiscal 2028, supporting management’s confidence in sustained growth momentum across its core data center and LoRa franchises.
