### VIDEO SCRIPT

Hi, I'm Chris Kubasik, Chair and CEO of L3Harris. On behalf of our colleagues around the world, we look forward to you joining our company. When completed, this acquisition will immediately benefit our customers who rely on the technology you deliver.

We recognize that Aerojet Rocketdyne is a national asset with a proven track record of innovation and excellence.

You have contributed to the most significant milestones in space exploration and discovery.

You have worked on rocket propulsion that supports America's warfighters and enhance integrated deterrence.

L3Harris will be fortunate to have your dedication, agility and innovative thinking. We can't wait to have you join our team.

It's an exciting time for our company. We are quickly building our reputation as the Trusted Disruptor in the Aerospace and Defense industry.

What does that mean? It means we're a non-traditional competitor focused on rapidly developing advanced capabilities that can adapt to growing national security threats.

And our three strategic priorities – Perform, Grow and Innovate – guide our efforts every day.

We're performing by building upon our solid foundation and operational rigor to execute safely, on time, and with high quality for our customers.

We are winning more contracts on critical programs globally in all domains, and we're leveraging innovation as a competitive advantage to help develop rapid solutions and stay ahead of global threats.

The addition of Aerojet Rocketdyne helps us in all of these areas.

We are passionate about our customers and excited about our purpose to create a safer and more secure future. Our two companies share very similar DNA and values, which will surely help us achieve a successful integration. Together, we will ensure that the defense industrial base and our customers have strong weapon systems and space propulsion to effectively address both current and emerging threats.

And will further promote scientific discovery and innovation through investments in hypersonics. I've been in and around the defense industry for over 35 years and I've always admired Aerojet Rocketdyne and its heritage companies. When this deal is finalized, we will keep the AR name to honor its legacy of innovation and excellence. It couldn't be a better time for use to join forces. I'm looking forward to our future together. Thank you.
