Dear [Valued Partner],

I am pleased to share some important news with you about Alteryx.

Today, we announced that Alteryx has agreed to be acquired by Clearlake Capital and Insight Partners. Clearlake and Insight are two of the most well-respected investment firms in technology and software. Their enthusiasm about Alteryx underscores the strength of our business and the value of our capabilities and innovation. Indeed, we know that data-driven decisions matter now more than ever, and we are proud to offer our customers a differentiated platform that is:

Through this transaction, we will gain access to increased working capital, industry expertise, and flexibility as a private company. Together, we will build on our achievements and accelerate our mission of harnessing the power of analytics to enable customers all over the world to transform data into a breakthrough. We are very excited about this agreement and the opportunities that we believe it will create for our company – and in turn our partners – to succeed and thrive.

Today’s announcement will have no impact on our day-to-day operations in the near-term. The transaction is not yet complete, and until it closes, we remain a publicly traded company. Your Alteryx contact remains the same; all current contracts continue as normal; and there are no changes in how we work with you.

The transaction is expected to close in the first half of 2024, subject to customary closing conditions and approvals. This should be seamless to you.

On behalf of the entire Alteryx team, thank you for your partnership. We value the relationship that we have built with you.

Sincerely,

Mark Anderson

CEO
