Segment Reporting
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 long-lived assets, including equipment, building, furniture and fixtures, operating ROU assets, finite-lived intangible assets, and maintenance spares, are not reviewed by Ciena’s chief operating decision maker for purposes of evaluating performance and allocating resources. As of November 2, 2024, equipment, building, furniture and fixtures, net, totaled $337.7 million, and operating ROU assets totaled $27.4 million both of which support asset groups within Ciena’s four operating segments and unallocated selling and general and administrative activities. As of November 2, 2024, finite-lived intangible assets, goodwill, and maintenance spares are assigned to asset groups within the following segments (in thousands):
