Adobe announced today that it has entered an agreement to acquire Day Software, a content management software company. Adobe has launched a public tender offer to acquire all of the publicly held registered shares of the company for about $240 million.

Adobe says the purchase would strengthen its enterprise software solutions, and allow it to help organizations create, manage, distribute, and monetize content while optimizing the web experience for their customers. Day Software users will be able to leverage Adobe’s AIR, Flash, Flex, LiveCycle and PDF technologies.

"Adobe’s acquisition of Day represents a key milestone in our efforts toward delivering best-in-class customer experience management solutions to enterprises and governments worldwide," says Rob Tarkoff, SVP and general manager of Adobe’s Digital Enterprise Solutions. "With the addition of Day to our enterprise portfolio, we will be able to enhance the value of our offering and deliver on our vision of the web as the hub of customer interaction."

"Organizations around the globe have recognized the importance of the online and mobile channel and turned to Day as their enterprise standard for next generation Web Content Management," adds Day Software CEO Erik Hansen. "We are excited to join Adobe and combine our expertise in WCM with technologies that create and deliver rich online and offline experiences leveraging the ubiquity of Flash and PDF. We believe this is a winning combination for both Adobe and Day customers."

Day will operate as a product line within Adobe’s Digital Enterprise Solutions Business Unit. Hansen will join Adobe, reporting directly to Tarkoff. Day provides more info on the acquisition.
