Ciena looks expensive against its earnings: it trades at about 30 times next year's estimated $10.68 a share, versus the 18 times the industry usually gets. That implies fair value of about $169-215, putting the stock 47% above the high end. The read leans on forecasts, since forward earnings are 226% above trailing, and is based on levels only, with no fundamental work. x.com 

Ciena looks dicey beyond the short term, in line with a Seeking Alpha article by Wail Shudar written shortly before its earnings plunge. A post the author replies to notes the stock is now technically in a much better place. x.com  x.com 

Ciena is 47% off its high after a valuation selloff despite strong hyperscaler-driven growth. Revenue grew 37% to $1.67B and adjusted EPS tripled. Backlog is $8.5B and expected to pass $10B by year-end, half of revenue now comes directly from hyperscalers, and data center revenue has quadrupled this year. Management's preliminary 2027 outlook of at least $8.3B implies another 30% growth, with supply tight until 2028. x.com 

Ciena's stronger moat justifies its richer valuation versus Credo, and its recent guidance was good. x.com 

Ciena's 30% drop from its high has nothing to do with the business, and both sell-off catalysts have now cleared. It beat EPS by 12%, grew revenue 40% and raised guidance to $6.3B, in line with consensus after a 200% run, while a $2.875B convertible added hedge selling through June 11. Hyperscalers are linking GPU clusters across cities and continents with 800G and 1.6T coherent optics, where Ciena leads data center interconnect, a market doubling to $50B by 2029. Backlog is $7.7B. x.com 

Ciena solves inter-data-center bandwidth constraints, one of AI's bottlenecks alongside compute and power, and it trades at a more compelling price after the July selloff. Its $7.7B backlog, with about 80% converting to revenue within a year, is chunky. x.com 

Ciena has a $640 price target as AI data center optical demand explodes, with a confirmed $7B backlog. x.com 

Ciena's selloff priced a slowdown from 35% to 30% growth, but most of that 30% is already sold at prices Ciena is still raising. Q3 revenue rose 37% to $1.67B, the FY26 guide rose to $6.42B, and the early FY27 floor is at least 30% growth with at least 45% gross margin. Backlog hit $8.5B, expected above $10B by year end, mostly with customer-requested 2027 dates. Ciena is raising prices from high single digits into the low 20s, even on signed orders, which no one does into softening demand. … Show more

Ciena's new 2029 margin target depends on price increases sticking after the optical shortage ends. Its investor forum set about $14bn of 2029 revenue, roughly 30% a year from 2026, adjusted gross margin near 50% and 32-35% operating margin. Orders grew 79% a year and backlog 118% from 2024 to 2026, and the CFO sees no supply-demand balance before 2028. But price hikes of high single digits to low 20s are a key margin lever, so whether fiscal 2027 margin holds 45-46% is the test. x.com 

Ciena is becoming an AI infrastructure story rather than a telecom equipment one, because bandwidth between data centers could become the next major constraint as AI capacity spreads across campuses and regions. Its CEO framed Ciena as a critical connectivity layer as larger AI clusters drive structurally higher optical networking demand. Per Bloomberg's framing, the selloff after a Q3 beat looks like an expectations and valuation reset, not weaker demand, possibly a better entry point. x.com
