Semtech's Q4 FY2026: Steady Growth and Strong Data Center Performance

Semtech reported Q4 FY2026 revenue of $274.4 million, a 0.4% beat over the street estimate of $273.2 million. The company's adjusted diluted earnings per share (EPS) came in at $0.44, a 2.3% beat over the estimated $0.43. While these figures represent a modest beat, they are consistent with the company's recent trend of steady, incremental growth.

Semtech's revenue has shown a consistent upward trend over the past few quarters. Q4 FY2026 revenue of $274.4 million represents a 2.8% increase from the prior quarter and a 9.3% increase year over year. This growth is particularly noteworthy given the challenging macroeconomic environment. The company's full-year revenue for FY2026 was $1,050.0 million, representing a 15% year-over-year increase, driven by continued strength in the data center and LoRa portfolios.

The gross margin for Q4 FY2026 was 50.3%, a decline from the 51.7% reported in Q3 FY2026. This decline is primarily attributed to the initial ramp costs from the HIFU acquisition, as noted by CFO Mark Lin. Despite this, the company's adjusted operating income of $50.0 million and adjusted EBITDA of $57.4 million both exceeded the midpoint of guidance, indicating strong operational performance.

The data center segment continues to be a key driver of Semtech's growth. Q4 FY2026 data center net sales reached a record $63.0 million, up 12% sequentially and 26% year over year. This strong performance is supported by the company's broad portfolio, including its market-leading FiberEdge ICs, which also set a new record for net sales. For the full fiscal year, data center revenues were a record $223.0 million, representing annual growth of 58%.

The infrastructure segment also showed strong growth, with net sales of $86.3 million in Q4 FY2026, up 11% sequentially and 25% year over year. This growth is driven by the data center business, which continues to benefit from strong demand for Semtech's broad portfolio of products. For the full fiscal year, infrastructure net sales were $310.0 million, up 27% over the prior year.

The industrial segment, which includes the TVS and PerSe product portfolios, reported net sales of $155.1 million for the fiscal year, up 5% year over year. The full-year industrial revenue was $584.0 million, representing 13% growth over the prior year. The LoRa-enabled net sales for Q4 FY2026 were $39.6 million, in line with Q3 and up 7% year over year, supported by continued expansion across several application verticals such as smart utilities, smart building, smart city, and asset management.

The IoT Systems and Connectivity business recorded Q4 net sales of $89.9 million, up 2% sequentially but down 3% year over year. For the full fiscal year, revenues were $354.0 million, up 9% compared to last year. Despite the slight decline in the quarter, the segment continues to show growth, driven by the expansion of LoRa technology.

Semtech's financial health remains strong, with operating cash flow for Q4 FY2026 reaching $61.5 million, up 30% from $47.5 million in the prior quarter and 84% from $33.5 million a year ago. Free cash flow for the quarter was $59.1 million, up 32% from $44.6 million in the prior quarter and 91% from $30.9 million a year ago. This strong cash flow generation is a positive indicator of the company's financial stability and ability to invest in future growth initiatives.

For Q1 FY2027, Semtech expects net sales of $283.0 million, plus or minus $5.0 million, representing a 13% year-over-year increase at the midpoint. The company's gross margin outlook for Total Semiconductor Products is expected to be 60.4%, plus or minus 50 basis points, down 130 basis points sequentially. Adjusted net operating expenses are expected to be $96.9 million, plus or minus $1.0 million, resulting in an adjusted operating margin at the midpoint of 18.6%. Adjusted EBITDA is expected to be $59.5 million, plus or minus $3.0 million, resulting in an adjusted EBITDA margin at the midpoint of 21%. Adjusted diluted earnings per share are expected to be $0.45, plus or minus $0.03, based on a weighted average share count of 96.6 million shares.

The tone of Semtech's guidance for Q1 FY2027 is positive, with the company expecting continued growth in net sales and maintaining strong financial metrics. The guidance reflects the company's confidence in its data center and LoRa portfolios, which continue to drive growth.

The tone of Semtech's earnings call for Q4 FY2026 was generally positive, with a sentiment score of 0.53 and a guidance tone of 0.55. The prepared sentiment score of 0.74 indicates a highly positive prepared script, while the QA sentiment score of 0.35 suggests a more moderate tone during the Q&A session. The company's AI optimism score of 0.68 and a relatively low uncertainty score of 55.9 further support the positive outlook.

Compared to the previous quarter, the sentiment score increased slightly by 0.01, while the guidance tone decreased by 0.27. The prepared sentiment score dropped significantly by 0.71, but the QA sentiment score increased by 0.17. The uncertainty score decreased by 15.4, and the QA evasiveness score increased by 18.0. Despite the mixed changes, the overall tone remains positive, reflecting the company's confidence in its growth prospects.

In the context of its peers, Semtech's performance is solid, though not as strong as some of the larger tech giants. For example, NVIDIA (NVDA) reported a revenue of $81.61 billion with a gross margin of 74.9% and a 85.2% year-over-year growth, significantly outpacing Semtech's metrics. However, Semtech's 15% year-over-year revenue growth and 50.3% gross margin are still respectable, especially given the company's focus on niche markets like data centers and IoT.

Semtech's focus on the data center and IoT segments aligns with broader industry trends. The data center market is expected to continue growing, driven by increasing demand for cloud services and data storage solutions. Semtech's strong performance in this segment positions the company well to capitalize on these trends. The IoT market, particularly the LoRa segment, is also expected to grow, with Semtech's guidance suggesting a long-term growth rate of approximately 20%.

While Semtech does not have any notable customers or suppliers listed, the company's strong performance in the data center and IoT segments suggests positive implications for its ecosystem. The growth in data center revenues indicates strong demand from cloud service providers and data center operators, which could benefit companies like Amazon and Microsoft. The expansion of LoRa technology in various application verticals also suggests potential opportunities for companies in the smart utilities and smart city sectors.

Semtech's Q4 FY2026 earnings report reflects steady growth and strong performance in key segments, particularly the data center and LoRa portfolios. The company's financial health remains strong, and the guidance for Q1 FY2027 indicates continued confidence in its growth prospects. While the overall tone of the earnings call was positive, the mixed changes in sentiment and guidance tone suggest a cautious optimism. Semtech's focus on niche markets and its strong financial metrics position it well for future growth, aligning with broader industry trends in data centers and IoT.
