Employee Note

Employee Note – February 12, 2024

Last week we made the major announcement that Everbridge has entered into a definitive agreement to be acquired by Thoma Bravo, one of the world’s leading and most experienced software investment firms. This is a monumental next step on our journey as a company and I fully appreciate that it comes with a lot of emotions, whether you are a long-time employee or whether you joined us through a previous acquisition. As a follow up to our initial All Hands meeting last Monday to announce the news, we look forward to more discussion over the coming weeks of what the transaction means for the future of Everbridge as a company, our employees, and our customers. While many of the details are still being worked out, I am incredibly optimistic about the road ahead.

Everbridge as a company has experienced an amazing 21-year history, growing from a simple but compelling vision of our founders after 9-11 that technology should be smart enough to reach everyone in a time of emergency. In a crisis, the safety of every individual should not be dependent on a single message delivery path. Over the ensuing two decades, Everbridge grew its leading mass notification platform to reach more than 2 BILLION people across the world over a broad range of modalities. We have continuously expanded our solution set to become the most robust critical event management leader, combining intelligent automation with the industry’s most comprehensive risk data, to support organizations with both digital and physical critical events. Based on the lifesaving work we enable, and the number of major brands and government agencies that we support, I believe Everbridge is one of the most meaningful software companies in the world, truly positioned to empower resilience for all!

Some of you have asked why the transaction was announced now. Well, first is our fiduciary duty to our shareholders which I described during our All Hands and in the written materials we shared last Monday. In addition, we still have A LOT of work to do to bring all the pieces of our company together and complete the vision. We have seen over the past couple of years the volatility and unwanted attention that being a company with publicly-traded stock creates – specifically following the Florida alert in April 2023 and in sharing our perpetual revenue shortfall in August 2023. Both created significant volatility in our share price, but neither affected our progression to our long-term goals. Transitioning from a public company, under the scrutiny of the financial markets, to a private company will not change our brand, our vision, our mission, or our purpose and will allow us to increase our focus and execute more efficiently for our customers.

I want to close by stating that I am aware that many of you are wondering what this news will mean for your role at Everbridge. While no decisions have been made and I do not have any details to share at this time, I do know that it is always in a company’s interest to implement any changes in as transparent a manner as possible. My experience with acquisitions is that buyers of companies work hard and effectively with companies to create opportunities for remarkable learning, professional growth, and productive rigor. While I do not yet know specifically what our future owner would have in mind for Everbridge, my expectation is that our journey together will continue to be rewarding, and that the mission and vision for Everbridge will thrive and grow.

In summary, in the short term, nothing is changing. We are continuing to execute as a standalone public company until the deal closes, which is currently anticipated to close in the second quarter of this year. The most important thing you can do is maintain focus on serving our customers and each other to the best of your ability. In the longer term, I am confident that we will continue long into the future our exceptional track record of helping companies accelerate the execution of their strategies and I fully expect that to be the case here with Everbridge. We’re an important company with a critical mission and a bright future.

Thank you for all you do, and…

Stay healthy and strong.
