Social customer solutions provider Lithium Technologies has purchased social media influence tool Klout, according to a Fortune report cited by Tech Cocktail. The transaction is priced at $200 million in combined cash and equity, the report said.

The two companies are set to appear in a joint press conference on Thursday in San Francisco. The exact terms and other details of the acquisition deal have not yet been disclosed, the report detailed.

It is not yet known if Klout's scoring tool will be integrated with Lithium's software as a result of the acquisition. In September, the latter announced that it had closed a $50-million funding round, wrote VentureBeat.

Launched in 2008 in San Francisco, Klout measures the social influence of social network users to be used by enterprises. In January 2012, it had received a large amount of capital from investors including Kleiner Perkins Caufield & Byers, Greycroft Partners, and FF Asset Management, the report added.
