Channel inventory in distribution dropped to 48 days, a historic low and well below the 70–75 day target, reflecting robust sell-through. Internal inventory was reduced by $22 million, supporting $48 million in operating cash flow despite a non-GAAP operating loss of $7 million. Distribution now accounts for 66% of revenue, illustrating the company’s broad reach into diverse end markets.
- Smart Metering Outpaces Expectations: India’s metering ramp progressed faster than anticipated, fueling I&C growth.
- Home & Life Nearly Doubles YoY: Connected health and smart home drove outsized gains, reinforcing secular demand tailwinds.
- Inventory Tightness Signals Demand Strength: Channel inventory at 48 days reflects hand-to-mouth supply for long-tail customers.
Margin expansion and disciplined inventory management support the company’s confidence in above-market growth, with new program ramps—not broad market recovery—providing the primary lift.
Executive Commentary
"Our home and life business grew mid-single-digit sequentially, nearly doubling year-over-year, as share gains and connected healthcare continued materializing into production ramps. In addition, smart home applications showed signs of strength in the quarter."
Matt Johnson, President and Chief Executive Officer
"Sell-through at our distribution partners continued to gain momentum with channel inventory decreasing by eight days to end at 48 days, which is down from 56 days in the prior quarter. This marks a new low level of channel inventory and is well below our targeted level of about 70 to 75 days."

Strategic Positioning
1. Design Win Ramps as Growth Engine
Growth is being driven by specific new product ramps—particularly in smart metering, connected healthcare, and electronic shelf labeling—rather than a broad macro recovery. Management emphasized that these design wins are broad-based and not concentrated in a single customer or application, providing a diversified foundation for continued outperformance.
2. Channel Inventory and Supply Chain Discipline
Channel inventory reached a record low of 48 days, reflecting strong end-market demand and tight supply chain management. The company plans a gradual rebuild toward its 70–75 day target over several quarters, ensuring working capital supports new design ramps without overextending inventory risk.
3. Product Portfolio Expansion: Series 2 and Series 3
Series 2 SoCs, system-on-chips, remain the cornerstone of current growth, with more than a billion units shipped and significant future shipments secured. Series 3, the next-generation platform, has begun production ramp and is expected to drive higher average selling prices (ASPs) due to increased wireless performance, compute, and AI/ML capabilities. Code compatibility between Series 2 and 3 is a unique differentiator, supporting customer stickiness and migration.
4. End Market Diversification and Secular Tailwinds
Silicon Labs is positioned across multiple secular growth vectors: connected health, smart home, smart metering, BLE (Bluetooth Low Energy), Wi-Fi, and Matter protocol adoption. The company highlighted Wi-Fi revenue up 40% and BLE up 80%, underscoring share gains in high-growth wireless connectivity markets.
5. Tariff and Trade Policy Resilience
Management asserts minimal direct exposure to current tariff rules, with a broad customer and application base limiting risk concentration. While indirect demand impacts remain uncertain, the company’s supply chain diversification and geographic spread reduce vulnerability to near-term trade shocks.
Key Considerations
Silicon Labs’ Q1 performance and guidance reflect a business model built on diversified design wins, operational discipline, and product innovation in the IoT (Internet of Things) space. The following considerations will shape investor focus in coming quarters:
Key Considerations:
- Design Ramp Sustainability: The durability of current ramps in smart metering, connected health, and shelf labeling will be critical to maintaining above-market growth.
- Inventory Rebuild Trajectory: Gradual channel inventory normalization is necessary to support demand without introducing excess risk.
- Series 3 ASP and Margin Impact: The pace and scale of Series 3 adoption will influence blended ASPs and long-term gross margin expansion.
- Tariff Uncertainty Monitoring: Indirect effects from global trade policy changes could impact customer demand, though direct exposure is limited.
Risks
Tariff volatility and global trade policy shifts remain a key external risk, with uncertain indirect effects on customer demand. Inventory normalization could lag if end-market sell-through softens, potentially leading to channel imbalances. Competitive pricing pressures, particularly from fabbed competitors, persist but have not yet materially impacted share or margins. Execution risk exists in scaling Series 3 production and maintaining design win momentum.
Forward Outlook
For Q2 2025, Silicon Labs guided to:
- Revenue of $185 million to $200 million (midpoint +32% YoY, +8% QoQ)
- Non-GAAP gross margin of 55% to 57%
- Non-GAAP operating expenses of $106 million to $108 million
- Non-GAAP EPS range: $0.19 to a loss of $0.01
For full-year 2025, management reiterated confidence in outperforming the broader semiconductor market based on new product ramps and secular growth drivers, not on a cyclical market rebound.
- Guidance is underpinned by continued linear improvement in bookings and no evidence of significant customer pull-ins.
- Gross margin progression is expected as mix shifts toward higher-value industrial applications and new platforms ramp.
Takeaways
Silicon Labs is executing on a strategy that de-risks macro cyclicality through diversified design wins and disciplined operations, with new product ramps and channel inventory management at the forefront.
- Secular Growth Engines: Smart metering, connected health, and shelf labeling are proving to be robust drivers, with additional upside from Wi-Fi, BLE, and Matter adoption.
- Operational Discipline: Inventory control and channel management are supporting margin expansion and working capital efficiency.
