Citi initiated coverage with a Buy rating and a $200 price target, raising sales and EPS estimates due to the ramp of the Scorpio PCIe switch.
The key thesis is that CPO is an add-on to scale-up switches like Scorpio X and UALink, not a replacement, with Scorpio sales expected to grow significantly.
Citi models strong EPS and EPS CAGR, and sees the company's retimer share and PCIe Gen6 leadership as durable competitive advantages despite increasing competition.
Citi models ~$6 in CY28 EPS (27% above Street), ~40%+ EPS CAGR over three years, and sees ALAB’s 97%/80% retimer share in CY25/CY26 and PCIe Gen6 leadership as durable moats even as MRVL competition intensifies.
CRDO -9% / ALAB -4%: your guess as good as mine
