The revenue figures are, as per IMS Health, for the 12 months ending December 31, 2011. National Oilwell Varco Buying CE Franklin Large-cap oilfield services company National Oilwell Varco Inc. ( NOV ) has agreed to acquire Canadian oil and gas production equipment supplier CE Franklin Ltd. (:CFK) for about C$240 million ($233.08 million) in cash. The transaction has been approved by the boards of both the companies but awaits regulatory and shareholder approval. In particular, the deal needs the go-ahead of at least two-thirds of CE Franklin shareholders at a special meeting scheduled for mid-July. We expect the buyout to conclude shortly after the shareholders vote. The world's biggest oilfield services provider, Schlumberger Ltd. ( SLB ), CE Franklin's largest shareholder, together with the firm's directors and executive officers – that collectively control 57% of the shares – have agreed to vote in favor of the transaction.
