ALAB Expands PCIe Portfolio With Aries 7: Can it Beat MRVL & CRDO?

ALAB unveiled Aries 7, billed as the industry's first PCIe 7 signal-conditioning portfolio for copper and optical interconnects, with initial sampling expected in Q4 2026.

The announcement lands on top of strong current numbers. PCIe 6 products generated over 50% of Q2 revenues, driven by record Aries sales. For Q3 2026, ALAB guides to revenues of $540-560 million, which represents roughly 40% sequential growth.

The competitive backdrop matters. MRVL and CRDO both operate in the AI connectivity space, and the headline framing pits ALAB against both. Our interpretation: being first to a PCIe 7 signal-conditioning portfolio gives ALAB a product-cycle narrative to defend its position, but sampling does not equal revenue. A Q4 2026 sampling window means PCIe 7 contribution sits beyond the current guidance period.

The near-term revenue story still rests on PCIe 6. With that generation already above half of Q2 sales, the Q3 guide of $540-560 million is the number that tests whether demand holds at the pace implied by ~40% sequential growth.
