Ciena drops 13% after earnings surprise as AI network demand meets mixed market reaction

Ciena Corp. stock is down a bit for the abbreviated holiday week, as traders look ahead to the June 4 earnings release. Investors are watching to see if the report justifies the buzz around AI-networking names. U.S. markets stay shut over weekends, and the NYSE says May 25, Memorial Day, is a market holiday in 2026.

Ciena shares finished Friday at $580.23, up 1.76% for the day. That’s still off about 0.6% from where they ended May 22 at $583.74. It was a volatile week for the stock, which hit $605.61 on Tuesday, then dropped the next two days before bouncing back Friday.

Ciena’s next catalyst is nearly here. The company plans to put out fiscal Q2 results before U.S. markets open Thursday, June 4, and management is set for an 8:30 a.m. Eastern webcast.

Options pricing is pointing to a possible 13% move around the announcement, Bloomberg options data cited by Investing.com says. This doesn’t point to up or down, only to expected volatility.

Ciena is seen posting earnings per share of $1.45 on $1.5046 billion in revenue, according to MarketBeat. That sets up a tough comparison after more investors bought in following the company’s March results.

Ciena reported first quarter revenue of $1.43 billion, a rise of 33.1% from the same period last year. Adjusted EPS came in at $1.35. The company uses adjusted EPS as a non-GAAP measure that removes certain expenses. CEO Gary Smith called demand “unprecedented” and “broad-based.” CFO Marc Graff said Ciena had a “record Q1 backlog.” Following the results, Ciena increased its fiscal 2026 revenue forecast to between $5.9 billion and $6.3 billion.

The broader market moved higher Friday. The S&P 500 closed up 0.2% for the day, ending the week 1.4% higher. The Nasdaq Composite ticked up 0.2% Friday, bringing its weekly gain to 2.4%, data from AP show.

Ciena’s big rally this year is in focus. Investor’s Business Daily said Saturday the stock is up over 140% since January, boosted by AI data centers buying more optical networking hardware.

Setup isn’t all positive. Morgan Stanley held its Equalweight rating and left the $405 price target on Ciena. The bank said demand talk was still bullish, but investors looked like they were pocketing gains in popular AI trades. Results from Lumentum, Cisco and Coherent showed demand is outpacing supply. Still, Morgan Stanley said supply issues and product mix could cap upside for gross margin. Gross margin is revenue minus product costs.

Ciena’s results this week aren’t only about beating forecasts. Investors want to see moves in order backlog, supply capacity, and the outlook for the July quarter. Signs that margins aren’t keeping up with revenue growth will also get attention.

Big numbers might keep the AI optical-networking rally going. Just an average report probably won’t do it.
