Rimage Team

A few years ago we embarked upon an exciting journey to transform our company. We’ve focused on optimizing our Rimage Disc Publishing business while supporting our company’s enterprise video strategy through the acquisition of Qumu. We’ve had success on both fronts and everyone should take pride in your accomplishments!

We are now entering a new chapter in our transformation, which is focused on restructuring Rimage and Qumu into separate businesses. I’m excited to announce that Rimage Disc Publishing is being purchased by Equus Holdings (www.equus-holdings.com). Upon closing, Rimage will become a standalone business within Equus’ portfolio of technology companies. Equus Holdings is a Minneapolis-based company that has evolved from a custom computer manufacturer to a portfolio of technology companies primarily in the business server and client computing markets (www.equuscs.com, www.intequus.com, www.serversdirect.com, and www.razorsync.com).

I have been closely involved in this process for the past several months and I believe this change is a great strategy for Qumu, Rimage and Equus. Separating Rimage and Qumu will enable both companies to focus on its core markets and maximize its business potential. Under the ownership of Equus, Rimage will operate as a standalone entity with the leadership, talent and assets necessary to focus on delivering best-in-class disc publishing solutions and customer support. I’m sure you have a lot of questions and there is a lot of information that we’ve prepared to help you learn more. To help you get started, please review the following:

Your manager will be contacting you to organize a meeting to review more details on this announcement. Please take the time to review the information above and think through your questions. I will be joining all of the team meetings and I’m looking forward to our discussions.

Sincerely

Chris Heim
