After an initial exploration of a sale two years ago, Investcorp has sold SourceMedia, a b2b publisher serving the financial and healthcare markets. Observer Capital is the buyer and it’s the first deal for the private equity firm since it was formed last year by Joseph Meyer, the CEO of Observer Media, which owns New York Observer. Terms of the deal were not released. However, when Investcorp put SourceMedia on the block in 2012, sources pegged a potential sale price at $60 million—a price that one source with knowledge of the deal says is a reasonable estimate.
