WATERLOO – Enterprise software firm Open Text Corp. completes its acquisition of Austin, Texas-based web content management firm Vignette Corporation for approximately $321 million in cash and shares. Now operating under the Open Text brand, Vignette will merge with Open Text, which says it will continue to support Vignette’s products and customers as it integrates both company’s solution into a single product line, from web publishing application to enterprise-class e-business platforms for large-scale deployments. “The new demands of social and digital media, and fast-growing user expectations for more personalized web interactions are placing enormous pressures on customers to keep up," says John Shackleton, president and CEO of Open Text. “This is an important area of innovation for us going forward as we expand our [enterprise content management] portfolio — Vignette will play a key role in this strategy.”
