AYX Transaction All-Employee Letter from Mark

Subject: An Exciting New Chapter for Alteryx

Team,

I am pleased to share exciting news about the future of Alteryx. Today, we are announcing that Alteryx has entered into a definitive agreement to be acquired by Clearlake Capital and Insight Partners for $4.4 billion. Upon completion of this transaction, Alteryx will become a privately held company. Clearlake and Insight are two of the most well-respected investment firms in technology and software. Insight, in particular, has been an investor in Alteryx over the past decade. Their enthusiasm about Alteryx and this agreement underscores the strength of our business, our technology and the talent and hard work of our entire team.

Over the past several years, we’ve successfully executed a comprehensive transformation strategy to enhance our go-to-market capabilities and establish a strong cloud and AI innovation roadmap. Today we take the next step in our journey. 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.

Clearlake and Insight are excellent partners with outstanding records of helping companies grow and thrive. In addition to supporting Alteryx as a current investor, Insight has invested in and helped scale more than 800 companies worldwide. Clearlake’s breadth and accomplishments are also impressive. Clearlake has over $70 billion of assets under management, and its principals have led or co-led over 400 investments, many in the firm’s core software and technology sector. Both Clearlake and Insight have great respect for our mission, people and technology, and they look forward to helping our company – and in turn our customers and partners – be even more successful.

In terms of next steps, the transaction is expected to close in the first half of 2024, subject to customary closing conditions and approvals, including approval by Alteryx stockholders. Until then, we remain a publicly traded company, and our business objectives, roles and responsibilities continue as usual. As you know, we are just a couple weeks out from the close of Q4 and fiscal 2023. Even with this news, I am counting on each of you to stay focused on doing what we do best: delivering for our customers and winning in the marketplace. Please reinforce with customers that it is business as usual at Alteryx and they remain our priority.

Attached is an FAQ to address questions that you may have. We will also be hosting a virtual all-hands meeting today at 9:30 am PT to discuss this announcement. I encourage you all to join to the extent you can. Details for attending the meeting will be distributed shortly.

On a personal note, I want to thank each of you for your contributions and dedication to Alteryx. This transaction is a remarkable milestone for our company, one in which you have all played an important role. I hope you share my excitement about the opportunities ahead and that you’ll join me in celebrating this momentous day.
