Risks & headwinds

Uncertainty and delay in cellular module business divestiture Near term

Ongoing process, but no specific timeline for completion or value disclosed.

Mitigation:Focused on bringing the process to a successful conclusion; interested parties are now spending on external consultants for due diligence.

Initial ramp costs and integration challenges for HieFo acquisition Q1 FY27

Total semiconductor products gross margin expected to be 60.4% in Q1 FY27, down 130 basis points sequentially, including initial ramp costs.

Mitigation:Integration is underway; management expects the transaction to be accretive to non-GAAP diluted EPS within the first year. Adding capacity to address demand.

Increase in adjusted normalized income tax rate FY27

Expected to be 17% for FY27, up from 15% in FY26.

Mitigation:Due to a geographical shift in pretax profits, not a controllable operational factor.

Quarter-to-quarter volatility in LoRa revenue Ongoing

Quarterly sales range from $35 million to $45 million, despite long-term growth rate of approximately 20%.

Mitigation:Due to project-based deployment of demand; management is excited about multiple growth drivers (Edge AI, multiprotocol, Amazon Sidewalk) to drive long-term growth.

What to watch in Q1 FY27

Q&A highlights

Asked about initial applications for HieFo's indium phosphide products, their qualification status with customers, and expectations for material revenue contribution.

Hong Hou explained that HieFo's initial product, Gain Chips for tunable lasers, is already in volume production and capacity-limited, expected to contribute high-teen millions in FY27. He noted that CW lasers for optical transceivers, targeting 3.2T, are receiving strong customer interest for samples, with capacity building underway.

“This product for 2027 probably will be contributing roughly about a high-teen level of revenue.”

Detailed narrative

Record Fiscal Year Performance

Semtech achieved record net sales of $1.05 billion for fiscal year 2026, marking a 15% annual growth, driven by strong performance in its data center and LoRa portfolios. Adjusted diluted EPS for the year was $1.71, a significant 94% increase over the prior year, reflecting disciplined execution and a differentiated product portfolio. The company also generated robust operating cash flow of $61.5 million and free cash flow of $59.1 million in Q4, exceeding full FY25 amounts.

Strategic HieFo Acquisition

Semtech acquired HieFo Corporation, a manufacturer of high-efficiency indium phosphide-based optoelectronic devices, including Gain Chips and CW Laser Chips. This acquisition is strategically important as data center architectures evolve to 1.6T and 3.2T, increasing the complexity of optical interconnects. By integrating HieFo's technology with Semtech's TIA laser drivers, the company aims to co-develop and co-optimize performance, increasing content opportunity from high single-digit dollars in an 800-gig module to about $80 in a 3.2T module.

Data Center Momentum and AI Infrastructure

Data center net sales reached a record $63 million in Q4, up 26% YoY, and $223 million for FY26, growing 58% YoY. Semtech expects data center revenue growth to exceed 50% YoY in FY27. The company's analog solutions address the critical need for power efficiency in AI infrastructure, enabling hyperscalers to scale next-generation architectures at 800G, 1.6T, and 3.2T. Strong demand for 800G TIA solutions continues, with 1.6T volume ramps expected to build throughout the year.

Advancements in Linear Optics and Copper Interconnects

Semtech is expanding its LPO IC portfolio with 1.6T LPO drivers and TIAs expected this year, and is actively developing NPO (near-package optics) MSA for low-power, high-density solutions, anticipating increased content. Active copper cable (ACC) is gaining significant traction, with Semtech co-authoring the ACC-MSA to establish common specifications and accelerate adoption. The company will demonstrate 1.6T ACCs and next-generation 448G CopperEdge chips at OFC, highlighting its position in hyperscale interconnects.

LoRa Ecosystem Expansion

LoRa-enabled net sales were $39.6 million in Q4, up 7% YoY, and $156 million for FY26, growing 34% YoY. The long-term growth rate for LoRa is projected at approximately 20%, with quarterly sales ranging from $35 million to $45 million. Key growth drivers include Edge AI integration, multiprotocol connectivity (LoRa Plus with Z-Wave, Zigbee, Thread/Matter), global network expansion, and mass market consumer adoption through Amazon Sidewalk, with Ring planning product launches in March.

IoT Systems and Connectivity Innovation

The IoT Systems and Connectivity business recorded Q4 net sales of $89.9 million. Semtech launched the AirLink RX400 and EX400, the industry's first rugged 5G RedCap routers, designed for mission-critical industrial deployments. These routers offer 5G performance with significantly reduced power consumption (less than 1 watt idle power), making solar and battery-backed deployments practical for remote utility, oil and gas, and transportation customers.
