Lumentum Holdings Inc.

We own and lease various properties in the United States and eleven other countries around the world. We use the properties for executive and administrative offices, product development offices, customer service offices and manufacturing facilities. Our current corporate headquarters, which we own, is approximately 124,000 square feet and located in San Jose, California. As of June 27, 2026, our leased and owned properties in total are approximately 3,100,000 square feet, of which we own approximately 2,136,000 square feet, including the 1,173,000 square feet manufacturing sites in Thailand, the 183,000 square feet manufacturing site in the United Kingdom, the 148,000 square feet manufacturing site in Greensboro, North Carolina, the 124,000 square feet on the San Jose campus, the 472,000 square feet manufacturing and R&D site in Japan, and the 36,000 square feet manufacturing and R&D sites in Slovenia. Leased sites include properties located in Canada, China, Hong Kong, Italy, Japan, Switzerland, Taiwan, the United States, and South Korea. We believe our existing properties, including both owned and leased sites, are in good condition and suitable for the conduct of our business.

From time-to-time we consider various alternatives related to our long-term facilities’ needs. While we believe our existing facilities are adequate to meet our immediate needs, it may become necessary to lease, acquire, or sell additional or alternative space to accommodate future business needs. In March 2026, we acquired a manufacturing facility in Greensboro, North Carolina, which mainly included land, building, machinery and equipment. In March 2026, we also completed the sale of two commercial real estate properties located in San Jose, California. The properties consist of commercial buildings used by us for administrative, research and development and manufacturing support activities. In March 2025, we completed a transaction to sell the land and building of a 250,000 square feet manufacturing facility located in Shenzhen, China. In July 2024, we completed a transaction to purchase the land and building of our wafer fabrication facility located in Sagamihara, Japan. Our lease of the building at the premises was terminated as a result of the purchase.
