Annodata saw a slight revenue slump in its results to March 2023, plagued by continuing supply chain issues.

As a result, the reseller has dropped five places in this year's ranking.

Owned since 2016 by Kyocera, Annodata counts HPE, Hyland, Microsoft and Mitel among its key vendors, as well as Kyocera itself.
