SLS and Compiled are expected to be fully integrated by the fourth quarter of 2019, enabling substantial cost savings once fully on-boarded. The acquisitions will be accretive to 2019 earnings and are projected to add $12 million of revenue in 2020.

“These transactions represent significant milestones for our company as we grow our business and expand our Information Governance and eDiscovery software offerings,” said Chris Weiler, CEO of KLD. “Strategic Legal Solutions’ robust client base will now have access to KLD’s extensive platform and Compiled’s ReadySuite offering will provide additional flexibility in how we address the industry’s unique data management needs. Together, these acquisitions broaden our customer base with the addition of key client relationships, strengthen our end-to-end technology platform and provide significant revenue opportunities for the future.”

“As we move towards the closing of the merger between KLD and Pivotal, we are excited to see Chris and his team identify and execute accretive tuck-in acquisitions that will drive long term value creation for all shareholders,” said Jonathan Ledecky, Chairman and CEO of Pivotal. “A disciplined M&A strategy is a core tenet to our investment thesis and an important driver of growth for KLD. We look forward to building on this momentum and continuing to execute on KLD’s M&A strategy.”

Strategic Legal Solutions offers eDiscovery and managed document review services primarily in New York and Michigan. The addition of a managed document review facility in Detroit, Michigan will bring KLD’s managed document review capabilities to 13 locations across six countries. Jay Horowitz, the CEO and founder of SLS and a 23-year industry veteran, will join KLD as Senior Vice President, Global Solutions Strategy and will continue to manage SLS’ key relationships with AmLaw 100 law firms and Fortune 100/500 corporations. “This is an exciting chapter for us as we join the KLD family,” said Mr. Horowitz. “Our clients, which include some of the largest corporations in the world, will soon benefit from KLDiscovery’s advanced technology, global footprint and ‘white glove’ customer service.”
