It’s with tremendous excitement that I am announcing KORE’s intention to go public. As many of you are well aware, KORE has been at the forefront of IoT for nearly 20 years. We have helped establish standards in practice today, provided some of the first services to the most successful brands in the world, and brought mission-criticality to the Internet of Things. Clearly, it has been a journey. As J.R.R. Tolkien phrased, “Little by little, one travels far.”

We have been fortunate to travel that journey with many of you. We have seen many of you sprout into industry leaders after starting with one single device, and others bring digital transformation to already impressive enterprises. In short, we’ve come a long way with many of you and this is only the beginning.

KORE recently announced it has entered into a definitive agreement with Cerberus Telecom Acquisition Corporation to become a publicly-traded company. Upon completion of the transaction, we believe that Cerberus will be a tremendous partner for KORE, along with other key institutional investors. We look forward to leveraging their knowledge and resources to bring the most advanced IoT solutions and services to customers like you.

Our commitment to serve you remains as strong as ever, and you should expect no change to your relationship with KORE. We will stay focused on our mission to deploy, manage, and scale, and bring connectivity, solutions, and analytics to meet your specific needs.

I would personally invite you to contact us if you have any questions at all.

All the best,

Romil Bahl

President and CEO, KORE
