Citi makes outrageous call on Ciena stock after earnings

Citi makes outrageous call on Ciena stock after earnings Peace Longe Wed, September 9, 2026 at 12:33 AM GMT+9 4 min read CIEN +6.23% C -0.27% Ciena (CIEN) just delivered one of its strongest quarters ever. Then the stock fell hard anyway.

That contrast has left many investors unsure of what to do next.

Citigroup has now stepped in with a call that stands out from other analysts, pointing to a much higher share price.

Here is what the bank sees, why the stock dropped, and what it means for you.

Citi reiterated a $658 price target on Ciena and kept its Buy rating.

The bank called the post-earnings selloff a buying chance, according to CNBC.

Atif Malik, Citi's managing director leading its semiconductor and networking coverage, sees further gains ahead.

Marvell has a $120 billion Google deal, so why did the stock plunge?

Malik framed Ciena's 30% growth guidance as "a floor that will move higher with increased supply."

His case rests on two things: Ciena's lead in optical transport gear, and a new wave of demand from AI data centers.

Ciena builds the high-speed optical equipment that moves data between data centers and across long distances.

AI has made that equipment more valuable, since AI clusters in separate buildings must move huge volumes of data at high speed.

Its fiscal third quarter was a record. Revenue rose 37% to $1.67 billion, and adjusted earnings jumped 215% to $2.11 a share, Ciena reported.

Ciena also raised full-year revenue guidance to $6.42 billion.

Direct cloud revenue climbed more than 80%, and its order backlog grew to $8.5 billion, heading toward $10 billion by year-end, according to Yahoo Finance.

One month into the current period, Ciena had already booked nearly as much as it did in all of Q3.

Even so, the raised guidance only edged past Wall Street's estimate, and fourth-quarter margins are set to ease.

Rivals also cut their targets, with UBS moving to $394 and B. Riley to $347, Investing.com reported.

Other networking names actually rose that day, so this was a Ciena-specific reaction, not a sector selloff.

The bull case is simple. Ciena dominates a part of the AI buildout that chipmakers cannot replace, and its backlog gives years of order visibility.

The bear case is in the details. Growth now depends on parts supply more than on new orders, and the shares trade at a rich price after their run.

Component supply eases, letting Ciena turn backlog into revenue faster.

Cloud and telecom customers keep spending at the current pace.

For a two-to-three-year holder, the $10 billion backlog offers real cash-flow visibility.

Customer concentration: Two customers made up 41.7% of revenue last quarter, Ciena disclosed. One lost account could hurt revenue.

Valuation: Shares trade above 105 times trailing earnings, which invites sharp swings.

Supply limits: Near-term sales are capped by parts availability, not demand.

Citi's $658 target is aggressive, but it rests on a real shift in how AI traffic moves.

The near-term risk is valuation and thinner margins, while the long-term appeal is a growing backlog.

If you expect AI spending to stay strong, Ciena is a direct way to own the network layer.
