Astera Labs, Inc. Common Stock, ALAB
On a non-GAAP basis, the semiconductor connectivity specialist posted earnings of $0.61 per share, exceeding the Street’s $0.54 projection. This represented a 13.66% upside surprise and extended the company’s streak of beating earnings estimates to four consecutive quarters.
Quarterly revenue climbed to $308.4 million for the period ending March 2026. This figure represents a robust 93% surge from the $159.44 million recorded in the year-ago quarter and topped analyst projections by 5.42%.
The company’s non-GAAP operating margin reached 36.2% for the quarter, while gross margin stood at 76.4% — reflecting a 70 basis point improvement from the preceding quarter.
Astera Labs closed the first quarter with $1.18 billion in cash and cash equivalents on its balance sheet. The company generated $74.6 million in operating cash flow during the period.
Next-Gen PCIe and Scorpio Portfolio Fuel Expansion
The company’s PCIe Gen6 product family has achieved significant market penetration, now contributing more than one-third of total revenue. With millions of ports already deployed, management emphasized Astera’s positioning as a frontrunner in advanced interconnect technology.
The Scorpio fabric switch portfolio is experiencing strong customer adoption. The newly launched Scorpio X 320-lane variant — designed specifically for in-network computing applications — has commenced initial customer shipments and is projected to become the company’s highest-revenue product line by the end of the current year.
On the memory connectivity front, Astera’s Leo CXL controller is progressing from limited private beta deployment toward broader commercial availability. The solution is slated for integration into Microsoft Azure M-series virtual machines during the latter half of this year.
Second Quarter Outlook and Margin Dynamics
Looking ahead to Q2, Astera provided revenue guidance ranging from $355 million to $365 million, suggesting sequential growth of 15% to 18%. The company expects non-GAAP earnings per share to land between $0.68 and $0.70.
Gross margin is anticipated to decline modestly to approximately 73% in the second quarter. Company leadership attributed this temporary compression to a one-time non-cash charge stemming from a customer contractual arrangement — representing roughly a 200 basis point headwind.
Operating expenses are projected to increase in the coming quarter. Non-GAAP operating expenses are guided to $128 million to $131 million for Q2, up from $123.9 million in the first quarter, reflecting continued investment in research and development alongside integration-related costs.
The XScale Photonics acquisition has been fully integrated, with the team now embedded within Astera’s design operations. High-volume shipments from its optical connectivity platform are targeted to begin scaling around 2027.
Management also acknowledged ongoing “pockets of supply challenges” across the broader semiconductor ecosystem, noting that inventory levels currently stand at approximately 75 days. The company emphasized its diversified backend manufacturing partner network as a strategic advantage for meeting customer demand through year-end.
Diluted share count is projected to increase modestly to around 184 million shares in the second quarter, compared to 181.2 million in Q1.
Prior to the earnings announcement, Wall Street’s consensus forecast for Q2 called for earnings of $0.55 per share on revenue of $309.72 million — figures that Astera’s guidance substantially exceeded. For the complete fiscal year, analysts currently expect earnings of $2.39 per share on revenue of $1.33 billion.
Shares of ALAB have appreciated roughly 21% since the beginning of the year, handily outpacing the S&P 500’s 5.2% year-to-date return.
