Item 7.01.  Regulation FD Disclosure.
As of November 26, 2012, there were 66,622,075 shares of Shaw Group Inc. (“Shaw”) common stock outstanding.

As previously announced, Shaw is holding a special meeting of its shareholders to approve its previously announced definitive merger agreement with Chicago Bridge & Iron Company N.V. (“CBI”) to acquire Shaw. The meeting will be held December 21, 2012, at 9 a.m. Central time at Shaw’s headquarters located at 4171 Essen Lane in Baton Rouge, La. Shaw’s shareholders of record at the close of business Nov. 30, 2012, will be able to vote on the merger proposal.

Shaw cannot complete the merger and shareholders will not receive payment unless the merger proposal is approved by the affirmative vote of the holders of at least 75 percent of the shares of Shaw common stock outstanding on the record date (excluding shares beneficially owned by “Related Persons,” as defined in Shaw’s charter), as well as the affirmative vote of at least a majority of the voting power present.  Accordingly, as an example, if there is no change in the number of shares outstanding prior to the close of business on November 30, 2012, the 5% ownership threshold for purposes of determining a “Related Person” would be 3,331,103.7 shares of Shaw common stock. In order to ensure that your and your affiliates’ shares are included in the calculation of whether the Supermajority Threshold for approval of the Shaw Transaction Proposal has been met, you should monitor the number of shares you beneficially own, in the aggregate, as of November 30, 2012, to ensure you do not meet the 5% ownership threshold on such date. In determining whether or not you are a “Related Person,” you should be aware that you will be deemed to beneficially own Shaw common stock if you have a right to acquire Shaw common stock pursuant to any agreement, or upon exercise of conversion rights, warrants, or options, or otherwise, as well as in other circumstances described in the joint proxy statement.

In connection with the merger, Shaw shareholders will receive approximately $46 per share in cash and stock ($41 in cash and .12883 shares of CB&I common stock). This represents a 72 percent premium to the price of Shaw shares ($26.69) at the close on July 27, 2012, the day before the merger agreement was announced.

Shareholders should be aware that not voting will have the same effect as a vote against the merger proposal. Shareholders are urged to vote by Internet, by telephone or by completing and mailing their proxy cards.
If you have any questions or need assistance voting shares, please contact Morrow & Co. LLC at 800.607.0088 or 203.658.9400.
