Semtech outlined three near-term priorities that will drive its strategy going forward:
1. Capturing growth opportunities in core assets through strategic investments
2. Focusing on the divestiture of non-core assets
3. Strengthening its winning culture
The company is accelerating its R&D roadmap for next-generation data center technologies, targeting initial sampling of 1.6T LPO drivers and TIAs before year-end. It also secured design wins with several leading U.S. hyperscalers for its 800G transceivers and expects 1.6T volume ramps to begin in early 2026.
Forward-Looking Statements
Looking ahead, Semtech provided a positive outlook for Q4’26, projecting net sales of $273.0 million (±$5.0 million), which represents continued growth. The company expects adjusted diluted earnings per share of $0.43 (±$0.03) and adjusted EBITDA of $56.0 million (±$3.0 million).
The detailed Q4’26 outlook is presented in the following slide:
Management noted that the Infrastructure end market is expected to see continued strength in data center applications, while the High-End Consumer segment should benefit from the integration of recently acquired force-sensing technologies. In the Industrial segment, the company anticipates ongoing growth in LoRa-enabled solutions across smart utilities, smart buildings, smart cities, and asset management applications.
The company’s focus on high-margin, high-growth segments, combined with its improved financial flexibility following the debt restructuring, positions Semtech well for sustainable growth in fiscal 2027 and beyond. With design wins across next-generation data center technologies and expanding applications in IoT connectivity, Semtech appears well-positioned to capitalize on key secular growth trends in its target markets.
