Irvine-based Ingram Micro Inc. bought NetXUSA in Greenville, S.C., on undisclosed terms.
Ingram Micro is the world’s largest distributor of technology products, with revenue of $43 billion in 2015.
NetXUSA has about $125 million in annual revenue and 1,200 U.S. clients, for whom it provides products and services that use the Internet for making phone calls, rather than traditional “public switched” telephone networks.
Ingram itself is in the midst of being acquired: the $6 billion acquisition by China-based Tianjin Tianhai Investment Co. Ltd. is expected to close in the second half of 2016.
Ingram Micro ended the trading day Thursday at a market cap of about $5.4 billion.
