PREFORMED LINE PRODUCTS CO

Our corporate headquarters is located in Mayfield Village, Ohio, and, at December 31, 2025, the Company maintained 26 manufacturing plants. We also maintain various sales, research and engineering, administrative offices and distribution centers throughout the world. None of these manufacturing plants, administrative offices or distribution centers are individually material to our operations. The facilities are situated in 3 states within the United States and in 19 other countries. We own the majority of our manufacturing plants, and our leased properties consist of manufacturing plants, research and engineering, sales, administrative offices and distribution centers.

We believe that our properties have been adequately maintained, are in good condition generally and are suitable and adequate for our business as presently conducted. The extent to which we utilize our properties varies by property and aligns with manufacturing needs. Most of our manufacturing facilities remain capable of handling volume increases.
