On a non-GAAP basis, the company reported earnings of $0.61 per share, comfortably beating the Street’s $0.54 forecast. This represents a 13.66% positive surprise — extending the company’s streak to four consecutive quarters of earnings beats.

Quarterly revenue totaled $308.4 million for the period ending March 2026. This figure reflects a 93% surge from $159.44 million recorded in the year-ago quarter, while also exceeding analyst estimates by 5.42%.

Non-GAAP operating margin reached 36.2% for the quarter, while gross margin landed at 76.4% — representing a 70 basis-point improvement from the previous quarter.

The quarter concluded with $1.18 billion in cash and cash equivalents on the balance sheet. Operating cash flow generated during the period totaled $74.6 million.

Gen6 PCIe and Scorpio Product Lines Show Strong Momentum

PCIe Gen6 offerings have emerged as a significant revenue driver, now representing more than one-third of total sales, with several million ports already deployed. Executives highlighted this achievement as evidence of the company’s leadership position in next-generation connectivity solutions.

The Scorpio fabric switch portfolio continues to gain market acceptance. The newly introduced Scorpio X 320-lane device — designed specifically for in-network computing applications — has begun initial customer shipments and is projected to become the company’s flagship product line by the end of this year.

Regarding memory solutions, the Leo CXL controller is transitioning from private beta testing and is scheduled for broader availability on Microsoft Azure M-series virtual machines in the coming months.

Second Quarter Outlook and Margin Considerations

For the second quarter, Astera provided revenue guidance of $355–$365 million, suggesting sequential growth of 15–18%. Non-GAAP earnings per share are anticipated to land between $0.68 and $0.70.

Gross margin is projected to moderate to approximately 73% in Q2. Company leadership attributed this decline to a one-time non-cash charge related to a customer arrangement — representing roughly a 200 basis-point headwind.

Operating expenditures are also trending higher. Second-quarter non-GAAP operating expenses are forecast at $128–$131 million, up from $123.9 million in the first quarter, primarily due to increased research and development investments and integration-related costs.

The recently completed acquisition of XScale Photonics has been integrated into Astera’s engineering facilities. High-volume production from its optical interconnect platform is slated to commence around 2027.

Executives also acknowledged “selective supply constraints” affecting the broader semiconductor sector, with inventory levels currently hovering around 75 days. The company emphasized its strategy of maintaining a diversified backend manufacturing partner network to meet customer demand throughout the remainder of the year.

Diluted share count is anticipated to increase modestly to approximately 184 million shares in Q2, compared to 181.2 million in the first quarter.

Wall Street’s current consensus forecast for Q2 calls for $0.55 in EPS on revenue of $309.72 million, though the company’s guidance substantially exceeded these projections. For the complete fiscal year, analyst consensus stands at $2.39 EPS with revenue of $1.33 billion.

ALAB shares have appreciated roughly 21% since the beginning of the year, significantly outperforming the S&P 500’s 5.2% gain over the same timeframe.
