Operating Segments and Geographic Information
Note 15. Operating Segments and Geographic Information
Our chief executive officer is our Chief Operating Decision Maker (“CODM”). The CODM allocates resources to the segments based on their business prospects, competitive factors, segment net revenue and segment profit. The CODM regularly reviews operating results to make decisions about resources to be allocated to the segments and to assess their performance.
Segment profit includes operating expenses directly managed by operating segments, including research and development, and direct sales and marketing expenses. Segment profit does not include stock-based compensation, acquisition or integration related costs, amortization and impairment of acquisition-related intangible assets, restructuring and related charges, and certain other charges. Additionally, we do not allocate corporate marketing and strategic marketing expenses and general and administrative expenses, as these expenses are not directly attributable to our operating segments.
We do not track all of our property, plant and equipment by operating segments. The geographic identification of these assets is set forth below.
Cloud & Networking
Our Cloud & Networking products include comprehensive portfolio of optical and photonic chips, components, modules, and subsystems supplied to cloud data center operator, AI/ML infrastructure provider, and network equipment manufacturer customers who are building cloud data center and network infrastructures. Our products enable high-capacity optical links in cloud, AI/ML and DCI applications, and communications service provider networks, including products for access (local), metro (intracity), long-haul (city-to-city and worldwide) and submarine (undersea) network infrastructure. Our Cloud & Networking products also support network equipment manufacturers building enterprise network infrastructure, including SANs, LANs, and WANs. These products enable the transmission and transport of data, video, and audio over high-capacity fiber-optic cables. We maintain leading positions in these fast-growing cloud and networking markets through our extensive product portfolio, including high-speed optical components and transceivers, reconfigurable optical add/drop multiplexers (“ROADMs”), coherent dense wavelength division multiplexing (“DWDM”) pluggable transceivers, and tunable small form-factor pluggable transceivers. Demand for our Cloud & Networking products is driven by the continual growth in network capacity required for cloud computing and services, including for AI/ML, streaming video and video conferencing, wireless and mobile services, and IoT.
Industrial Tech
Our Industrial Tech products include short pulse solid-state lasers, kilowatt-class fiber lasers, ultrafast lasers, diode lasers, and gas lasers, which address applications in numerous end-markets. In the consumer end-market, our laser light sources are integrated into our customers’ 3D sensing cameras, which are used in mobile devices, payment kiosks, and other consumer electronics devices to enable applications including biometric identification, computational photography and virtual and augmented reality. In the automotive end-market, our lasers are used in our customers’ LiDAR and other optical sensor devices, which are increasingly being used in advanced driver assistance systems (“ADAS”) and in-cabin driver and occupant monitoring systems. In the industrial manufacturing end-market, our lasers are incorporated into our customers’ manufacturing machine tools used for the precision processing of materials in a range of industries including semiconductor device and microelectronics fabrication, electric vehicle and battery production, metal cutting and welding, and advanced manufacturing. Our products can also be used in the industrial end-market in imaging and sensing systems for process feedback and control, quality assurance, and waste reduction. Adoption of our products in the industrial end-market is driven by the needs of customers to advance semiconductor and microelectronics industry roadmaps, and by Industry 4.0/5.0 trends, including increasing manufacturing precision and flexibility and reducing waste and environmental impact. Demand for our products in the industrial end-market is driven by end-customer investments in manufacturing capacity. Our lasers also address certain
semiconductor inspection and life-science applications.
Reportable Segments
The two operating segments, Cloud & Networking and Industrial Tech, also represent our two reportable segments. Our CODM allocates resources and evaluates segment performance based on segment revenue and segment profit. The following table summarizes segment profit and a reconciliation to the consolidated income (loss) before income taxes for the periods presented (in millions):

Concentrations
We operate in three geographic regions: Americas, Asia-Pacific, and EMEA (Europe, Middle East, and Africa). Net revenue is assigned to the geographic region and country where our product is initially shipped. For example, certain customers may request shipment of our product to a contract manufacturer in one country, which may differ from the location of their end customers.
The following table presents net revenue by the three geographic regions we operate in and net revenue from countries that generally represented 10% or more of our total net revenue (in millions, except percentage data):
