Dear Valued [Customer/Partner],

I am writing to share some exciting news about Infoblox. Today we announced that we have entered into an agreement to be acquired by Vista Equity Partners, a leading private equity firm focused on software, data and technology-enabled businesses. A copy of the press release regarding the news can be found here.

In case you’re unfamiliar, Vista is a respected investment firm with a track record of helping companies achieve operational, product and customer service excellence. They are deeply knowledgeable about our industry and their support and professional expertise will help us as we continue to deliver the industry-leading products, solutions and customer services on which our partners and customers rely. Importantly, Vista sees that customers value our product portfolio and strategic roadmap, understands our critical position in the network provides unique visibility, context and control point, and agrees we have tremendous opportunity to deliver actionable network intelligence with integrated security and cloud capabilities.

We expect the transaction to be completed in our fiscal second quarter.
