SoundThinking’s Recent Announcement (Form SC14D9C)

Subject: SoundThinking's Recent Announcement

Dear Valued Partner -

I wanted to share an important update regarding SoundThinking. We recently announced that SoundThinking has agreed to be acquired by Transom Capital Group ("Transom").

By way of background, Transom is a seasoned investor that works collaboratively alongside companies and their teams to capture new growth opportunities. Their interest in SoundThinking is a testament to the importance of our mission and the progress we have made transforming into a broader public safety platform.

We believe that our agreement with Transom maximizes value for shareholders while best positioning our business for our next phase of success. We believe that moving forward as a private company with Transom will enable us to be an even stronger partner to you.

Looking ahead, we will be able to operate with greater flexibility to better support customers and deliver on our mission of helping communities become safer and more resilient through data and technology.

Next Steps

While this announcement is an exciting milestone for SoundThinking, nothing changes today. The transaction is expected to close in the fourth quarter of 2026, subject to customary closing conditions, including the completion of the tender offer by Transom for our shares. Until then, we remain a standalone company.

Our focus, as always, remains on providing the important solutions for public safety and security that help save lives, solve crimes and protect our communities. We are continuing to partner with you as we always have. There are no changes to our day-to-day operations or your company contacts.

We will continue to keep you informed as we move forward. If you have any questions, you can always reach out to your normal SoundThinking contact.

We value our relationship with you and look forward to working together now and in our next phase to make our communities safer.

Thank you for your support of our business.

Best,

[Name]
