Ciena^® Corporation (NYSE: CIEN), the global leader in high-speed connectivity, held its Investor Forum today at its R&D facility in Ottawa, Ontario, Canada and announced its three-year financial targets. These targets are set forth below.

Ciena’s three-year financial targets for fiscal year 2029 include:

• Revenue CAGR of approximately 30% from 2026 through 2029;
• Adjusted (non-GAAP) gross margin of approximately 50%;
• Adjusted (non-GAAP) operating margin in the range of 32% to 35%; and
• Free cash flow margins of approximately 20%.

"The three-year financial targets announced today reflect both the opportunities we see ahead and our confidence in our ability to execute,” said Marc Graff, Ciena’s Chief Financial Officer. “Backed by a differentiated portfolio, growing customer demand, expanding supply capacity, and new addressable market opportunities, we are well-positioned to deliver sustained revenue growth, significant profitability expansion, and attractive returns for our owners over the coming years."

Ciena also announced a change to financial reporting segments beginning with fiscal 2027 to be reflected in Q1 fiscal 2027 results. Graff continued, “Our new reporting segments - Optical Systems, Interconnects, Global Services, and Routing and Other - will align well with our growth markets and allow our owners improved insight into our financial performance.”

Ciena is hosting an investor forum Wednesday, September 16 and Thursday, September 17, 2026, during which executives will discuss Ciena’s strategic priorities and portfolio roadmap that underwrite its financial objectives. The content of Mr. Graff’s and Mr. Rothenstein’s presentations, which include information about Ciena’s recent financial performance, one-and three-year financial targets, addressable market sizing, and future financial reporting segments to align with these opportunities has been made available in the Events & Presentations section of the Investor Relations section of Ciena’s website.

With respect to Ciena’s expectations under “Ciena’s three-year financial targets for fiscal 2029” above, Ciena is not able to provide a quantitative reconciliation of the adjusted (non-GAAP) gross margin, adjusted (non-GAAP) operating expense, and adjusted (non-GAAP) operating margin guidance measures to the corresponding gross margin, operating expense, and operating margin GAAP measures without unreasonable efforts. Ciena cannot provide meaningful estimates of the non-recurring charges and credits excluded from these non-GAAP measures due to the forward-looking nature of these estimates and their inherent variability and uncertainty. For the same reasons, Ciena is unable to address the probable significance of the unavailable information.
