Astera Labs reported a record quarter last night, and guidance that is higher still.
What was reported
| Quarter | Y/Y | Q/Q | |
|---|---|---|---|
| Revenue | 392.4 | +104% | +27% |
| GAAP gross margin | 73.3% | ||
| GAAP operating income | 89.2 | ||
| GAAP operating margin | 22.7% | ||
| GAAP net income | 153.1 | ||
| GAAP EPS | $0.83 |
In millions of dollars
And in non-GAAP terms: gross margin 73.7%, operating income $153.5 million, operating margin 39.1%, net income $145.8 million and EPS of $0.80.
The line worth understanding
GAAP profit exceeds non-GAAP - and that is not normal
Almost always non-GAAP profit is higher than GAAP, because costs like share-based compensation are stripped out.
Here it is reversed: $153.1 million GAAP against $145.8 million non-GAAP, and $0.83 per share against $0.80.
The explanation is tax. The company's GAAP tax rate is very low, and it guides next quarter to a GAAP tax rate of about 4% against a non-GAAP rate of about 12%.
The practical meaning: GAAP profit here benefits from a tax effect, not from operations. Anyone comparing that $0.83 to prior quarters should know that tax is part of the explanation.
And the number that draws the eye: the guidance
For the third quarter the company guides to $540 to $560 million.
Against $392.4 million this quarter, the midpoint is growth of roughly 40% - within a single quarter.
And that is an acceleration, not a continuation: sequential growth this quarter was 27%.
The rest of the guidance: gross margin of about 72%, GAAP EPS of $0.87 to $0.92, and non-GAAP EPS of $1.16 to $1.21.
Worth noting that the guided gross margin is slightly below what was achieved - about 72% against 73.3%. That is what happens when the product mix shifts toward more complex hardware.
What is driving it
The release, quoting Jitendra Mohan, points to one product:
"We expect momentum to accelerate in Q3 as Scorpio fabric switches become our largest product family, one quarter ahead of our prior expectations."
This is the Scorpio X-Series 320-lane Smart Fabric Switch, now entering production.
And that is a change of substance, not just another product. Until now Astera Labs sold mainly signal conditioning components - redrivers and retimers that let a signal travel further within the rack. A fabric switch is an entirely different component: it routes traffic between the accelerators.
In the company's words, it marks its evolution into "a complete AI fabric infrastructure provider".
And alongside it, the Aries product family posted a record quarterly revenue of its own.
And the precise place in the chain
This is the smallest link among those we covered this week, and it sits inside the rack itself.
Arista connects racks to each other. Astera Labs connects within the rack - between the accelerators, processors and memory sitting in the same cabinet.
And the company notes it works in coordination with AMD, Arm, Intel and Nvidia - all four major processor suppliers, rather than one.
It is also expanding into optical interconnects - which puts it in the same field where Tower reports a $680 million annual run rate.
My Angle
A personal opinion of Ilan Abramov - not advice, not a recommendation
This company is small relative to the others we covered this week, and that is exactly why it is interesting.
$392 million in a quarter is a fraction of AMD's $11.5 billion. But the growth rate here - 104% year over year, with guidance for another 40% in a single quarter - is the highest of anything I read this week.
And what I look for in a report like this is whether the growth comes from an existing product or a new one. Here the answer is explicit: Scorpio, a fabric switch, becoming the company's largest family a quarter earlier than expected. That is not an extension of the same business - it is entry into a new category.
And what I flag as caution: GAAP profit exceeding non-GAAP. That comes from a low tax rate, not from the business. Anyone looking at $0.83 per share and comparing it to prior quarters is comparing a number shaped by a tax effect - and the company itself guides to the same gap next quarter.
And what I note: gross margin is guided down to 72% from 73.3%. That is reasonable when moving from selling components to selling switches, but it does mean the fast growth arrives with a slightly less profitable mix.
