Allegro MicroSystems Delivers Strong Q4 FY2026, Outpacing Street Estimates

Allegro MicroSystems [ALGM] reported a strong finish to fiscal year 2026, with Q4 revenue of $243.2 million, marking a 6.1% sequential increase and a 26.1% year-over-year growth. This performance is particularly noteworthy given the challenging macroeconomic environment. The company's full-year revenue of $890 million represents a 23% year-over-year increase, driven by strong demand in automotive and industrial segments.

The company's gross margin for Q4 FY2026 was 47.1%, a significant improvement from 41.4% in Q4 FY2025. This margin expansion is a testament to the company's operational efficiency and the high-margin nature of its product portfolio. The full-year gross margin of 49.4% further underscores the company's ability to maintain profitability despite market headwinds.

Allegro's revenue breakdown reveals a balanced growth across its key segments. However, the automotive segment saw a 17% year-over-year increase, with focused auto sales (excluding EV and ADAS) growing by 30% year-over-year to $349 million.

The industrial and other segment showed significant strength, with revenue increasing by 23% sequentially to $79 million and 49% over Q4 of FY2025. This growth was particularly driven by the data center market, which more than quadrupled and represented 10% of the company's total FY2026 sales. Magnetic sensor sales increased by 2% sequentially to $141 million, a 21% increase over the prior year quarter. Power product sales also saw a slight increase of 12% sequentially to $102 million and a 35% increase over the prior year quarter.

Allegro's operating expenses were $84 million, an increase of $5 million sequentially, primarily due to annual payroll tax resets and higher incentive compensation. Despite this increase, the company maintained an operating margin of 15.6% of sales, an improvement from 15.4% in Q3 and a significant 660 basis points increase from 9% in Q4 of fiscal 2025. CFO Derek D'Antilio highlighted the company's operating leverage: "Non-GAAP EPS increased by 13% sequentially and 183% over a year ago quarter on sales increases of 6% and 26%, demonstrating the significant operating leverage in our business model."

The company's interest expense was $5 million, which included $650,000 of expenses related to the repricing of its term loan down another 25 basis points to SOFR plus 175 basis points. The fourth quarter diluted share count was 187 million shares, and net income was $32 million or $0.17 per diluted share. Adjusted EBITDA for the year was 19.1% of sales, and earnings per share were $0.54, more than double the prior year.

Allegro's cash flow performance was strong, with free cash flow of $19 million in Q4 FY2026, contributing to a full-year record of $125 million. The company also made $60 million in voluntary debt payments, demonstrating its commitment to financial discipline. CapEx for the quarter was $17 million, reflecting ongoing investments in capacity expansion and technology development.

Operating expenses are expected to decline sequentially to $80 million, plus or minus $2 million. As a result, the company expects non-GAAP EPS to be between $0.19 and $0.23 per share. CFO D'Antilio also noted: "So we see some of that benefit going into our first quarter with a drop who's actually closer to 70% in the first quarter at the guide of 50% to 51%."

This guidance reflects the company's confidence in its ability to continue driving growth and profitability, supported by strong demand in key markets and operational efficiencies.

Allegro's strong performance in Q4 FY2026 has positive implications for its key markets, particularly automotive and industrial. The company's focus on high-efficiency power solutions and advanced sensor technologies positions it well to capitalize on the ongoing transition to electric vehicles (xEVs) and the growth in data center infrastructure.

While Allegro does not have any notable customers or suppliers listed, its success in these segments suggests a positive read-through for its peers and suppliers in the semiconductor industry. The company's emphasis on 800-volt xEV platforms and higher power AI architectures, as noted by CEO Michael Doogue: "Our power-through architecture delivers up to 40% greater efficiency -- and we expect to see a 2 to 3x dollar content uplift from isolated gate drivers as customers move toward 800-volt xEV platforms and higher power AI architectures," indicates a significant opportunity for growth in these areas.

In the context of its peers in the Analog Sensors subsector, Allegro's performance stands out. For Q4 FY2026, the company's revenue growth of 26.1% year-over-year is higher than the average growth rate of its peers, which includes companies like Analog Devices (ADI) with a 37.2% growth rate, Skyworks Solutions (SWKS) with a -1.0% growth rate, and Qorvo (QRVO) with a -7.0% growth rate. Allegro's gross margin of 47.1% is also competitive, falling between ADI's 67.3% and SWKS's 40.8%.

Allegro's strong financial performance and positive outlook position it well to continue outpacing its peers in the coming quarters. The company's focus on high-growth segments and operational efficiency is a key differentiator in a competitive market.

In conclusion, Allegro MicroSystems [ALGM] delivered a strong Q4 FY2026, outpacing street estimates and demonstrating significant operational leverage.
