Automotive revenue, anchored by XEV and ADAS, grew 17% and continues to outpace industry production rates due to content expansion and share gains. Notably, “Focus Auto” (XEV and ADAS) accounted for 55% of automotive sales, growing 30% for the year.
Industrial and other sales surged 38% for the year, led by a data center segment that quadrupled and reached 14% of Q4 sales. Robotics and automation also doubled year-over-year, reflecting early traction in factory automation and humanoid robotics. Sequentially, power product sales outpaced sensors, up 12% in Q4, as Allegro’s high-efficiency drivers and current sensors gained adoption across multiple verticals.
- Data Center Penetration: Content per AI rack is scaling from $150 to $425 as power density and architecture complexity rise.
- Operating Leverage: Q4 non-GAAP EPS nearly tripled YoY, reflecting significant drop-through on incremental sales.
- Geographic Breadth: Asia (ex-China) and China drove regional growth, with rest of Asia up 44% and China up 36% YoY, underpinned by data center and auto wins.
Allegro ended the year with record free cash flow, a strengthened balance sheet, and a multi-year high in design win backlog. The company’s Q1 guidance calls for continued double-digit growth, with gross margin stability and operating expense discipline supporting further earnings expansion.
Executive Commentary
"Our data center content is not limited by unit volume growth. We are seeing strong growth as a result of our expanding product portfolio and the adoption of new high voltage data center architectures. As AI racks move from 15 kilowatt to one megawatt of power consumption, Allegro's content scales with power per rack."
Mike Duke, President and CEO
"We improved our gross margin by 140 basis points, even with the annual price declines, even with the cost headwinds. We'll continue to do that as we go into 2027 and look to do select price increases as we move throughout the year."
Derek D'Ancilio, Chief Financial Officer
Strategic Positioning
1. Data Center Growth Engine
Allegro is leveraging secular AI and cloud trends to expand its data center footprint, with content per rack rising as new architectures demand higher power density and advanced sensing. The company’s high-speed current sensors and motor drivers are gaining share in power supplies and network equipment, positioning Allegro as a critical supplier as AI infrastructure scales.
2. Automotive Content and Share Gains
Focus Auto (XEV and ADAS) remains a core growth vector, supported by design wins in steering, braking, and high-voltage inverters. The company’s content expansion strategy is driving above-market growth, with dollar content per vehicle rising as electrification and ADAS adoption accelerate globally, especially in China.
3. Technology Leadership in Sensors and Power ICs
Allegro maintains the top position in magnetic sensing, with TMR (tunnel magnetoresistance) sensors and isolated gate drivers enabling higher accuracy, bandwidth, and efficiency. The release of the industry’s first 10 MHz TMR IC and expansion into fail-safe angle sensors for steer-by-wire ADAS systems underscore Allegro’s innovation pipeline.
4. Margin Expansion via Cost Programs
Despite commodity headwinds, Allegro is executing on gold-to-copper conversion and factory efficiency initiatives, offsetting inflation and supporting gross margin improvement. Select price increases and ongoing cost negotiations with suppliers are expected to further bolster margins in FY27.
5. Diversification Across End Markets
Robotics, automation, and energy infrastructure are emerging as meaningful contributors, with design wins in humanoid robotics and factory automation broadening Allegro’s industrial exposure and reducing reliance on auto cyclicality.
Key Considerations
Allegro enters FY27 with momentum across its highest-value verticals, but must navigate commodity inflation, supply chain dynamics, and evolving customer architectures.
Key Considerations:
- Data Center Mix Shift: Current sensors now comprise nearly 20% of data center sales, up from zero a year ago, signaling a broadening product contribution.
- Automotive Backlog Strength: Multi-year high in design wins and backlog, with China ADAS leading new program ramps.
- Operating Leverage Sustainability: Q4 margin gains were supported by annual price resets and efficiency, but future gains will depend on volume growth and successful cost conversion programs.
- Regional Demand Drivers: Asia-Pacific remains the fastest-growing geography, reflecting both auto and industrial traction.
- CapEx and Capacity: Increased CapEx in Q4 is targeting backend expansion in the Philippines to address rising demand and delinquency in both auto and industrial channels.
Risks
Key risks include exposure to commodity price volatility (especially gold and fuel), potential wafer supply constraints as mature node foundry capacity tightens, and sensitivity to auto and data center investment cycles. While management is executing on cost reduction and select pricing actions, margin expansion is contingent on both external inflation trends and successful execution of conversion programs. Competitive intensity in sensors and power ICs, as well as macroeconomic shifts in end markets, present ongoing uncertainty.
Forward Outlook
For Q1 FY27, Allegro guided to:
- Sales of $245 to $255 million (midpoint up 23% YoY)
