SEGMENT AND ENTITY WIDE DISCLOSURES
Operating segments are defined as components of an enterprise that engage in business activities that earn revenue and incur expense, for which discrete financial information is available, and for which such information is evaluated regularly by the chief operating decision maker for purposes of allocating resources and assessing performance. Ciena has the following operating segments for reporting purposes: (i) Networking Platforms; (ii) Platform Software and Services; (iii) Blue Planet Automation Software and Services; and (iv) Global Services. Ciena’s chief operating decision maker (“CODM”) is its chief executive officer, Gary Smith, who evaluates Ciena’s performance and allocates resources based on segment profit (loss) as compared to annual targets for these four operating segments.
Segment Profit (Loss)
The table below sets forth Ciena’s segment profit (loss) and the reconciliation to consolidated net income for the respective periods indicated (in thousands). The CODM excludes the following items in his assessment of performance of the operating segments: selling and marketing costs; general and administrative costs; significant asset impairments and restructuring costs; share-based compensation expense, amortization of intangible assets; acquisition and integration costs; interest and other income, net; interest expense; loss on extinguishment and modification of debt; and provision for income taxes. Effective as of the fourth quarter of fiscal 2025, Ciena recast its segment profit (loss) to align with the CODM assessment of performance of the operating segments to exclude share-based compensation expense. This change affects only the presentation of such information:

Entity Wide Reporting
Ciena’s long-lived assets, including equipment, building, furniture and fixtures, operating ROU assets, finite-lived intangible assets, goodwill, and maintenance spares, are not reviewed by Ciena’s CODM for purposes of evaluating performance and allocating resources. As of November 1, 2025, equipment, building, furniture and fixtures, net, totaled $386.8 million, and operating ROU assets totaled $38.6 million both of which support asset groups within Ciena’s four operating segments and unallocated selling and general and administrative activities. As of November 1, 2025, finite-lived intangible assets, goodwill, and maintenance spares are assigned to asset groups within the following segments (in thousands):

About Segments Disclosures

Segment disclosures break a company into its reportable operating units, revealing revenue, profit, and asset allocation that consolidated financial statements obscure. Under ASC 280, segments must match how the chief operating decision maker views the business, providing a window into internal management structure and resource allocation priorities.

Key signals: compare segment margins to identify which units drive profitability and which destroy value. Watch for changes in the number of reportable segments — segment aggregation or disaggregation often coincides with strategic shifts or attempts to obscure declining performance. Intersegment elimination patterns reveal internal pricing practices. The reconciliation between segment totals and consolidated figures exposes corporate overhead allocation and unallocated items. Geographic revenue concentration highlights regulatory and currency exposure. Compare segment-level capital expenditure against segment revenue to assess where management is investing for future growth versus harvesting existing assets.
