Astera Labs (NASDAQ: ALAB) delivered a robust preliminary second-quarter report and a third-quarter outlook that significantly exceeded Wall Street's expectations, sending shares on a volatile ride in after-hours trading on Tuesday. The company, a key player in connectivity solutions for AI and cloud infrastructure, projects revenue of $550 million for the September quarter, a figure that towers 31.9% above the prior consensus forecast.
The preliminary second-quarter results showed revenue of $392.4 million, up 104% year-over-year and 8.7% ahead of analyst estimates. Adjusted earnings per share of $0.80 also surpassed expectations by 15.9%. The company attributed the strong performance to record sales of its Aries products, as well as robust demand for its AI fabric and signal conditioning solutions.
Chief Executive Jitendra Mohan highlighted the accelerating momentum, stating that the Scorpio fabric switches are expected to become the company's largest product family a quarter earlier than previously anticipated. This optimistic outlook is underpinned by growth in the X-Series 320-lane production, which is supporting the projected sequential revenue increase of 40.2% in the third quarter.
The company's guidance also points to a significant expansion in operating leverage. Based on the midpoint of the revenue range and the company's adjusted operating expense forecast, adjusted operating margin is projected to reach approximately 43.3% in Q3, up from 39.1% in the second quarter. This improvement comes despite a projected 170-basis-point decline in gross margin, as operating costs are expected to rise at a much slower pace than revenue.
Calculations from the preliminary data show that adjusted operating income could surge by 55.1% sequentially, reaching $238 million, while adjusted operating expenses are only expected to increase by 16.4% to $158 million. This operational leverage is a key focus for investors, as it demonstrates the company's ability to scale efficiently even as product mix shifts.
The company's balance sheet remains strong, with cash and marketable securities totaling $1.25 billion as of June 30. However, there was a notable build in working capital, with receivables more than doubling from December and inventory climbing by 93%, underscoring the importance of monitoring shipment timing and cash conversion in the coming quarters.
Shares of Astera Labs ended the regular session up 12.65% at $361.67 ahead of the earnings release. In after-hours trading, the stock initially jumped over 4% before reversing course to fall 3.1% to $350.46 by 17:00 EDT. The volatility reflects the market's reaction to the strong guidance and the company's ability to meet heightened expectations.
Analysts have taken notice of the company's accelerating growth. Morgan Stanley's Joseph Moore raised his price target on the stock to $335 from $240 on Monday, maintaining an Overweight rating. The note also lowered the price target for GlobalFoundries (NASDAQ: GFS) to $57 from $65, while expressing optimism about both companies' long-term AI growth prospects.
Risks to the outlook include the timely ramp-up of Scorpio, high customer concentration, and potential geopolitical or tariff disruptions. Additionally, the company excluded $64 million in stock-based compensation from its adjusted results. As Astera Labs works to convert its Scorpio ramp into sustained operational leverage, investors will be closely watching execution in the quarters ahead.
