Murphy Oil (MUR) 8-K Unaudited pro forma condensed consolidated financial statements

Exhibit 99.1

Unaudited pro forma condensed consolidated financial statements

The unaudited pro forma condensed consolidated financial statements of Murphy Oil Corporation have been derived from its historical consolidated financial statements and are being presented to give effect to certain corporate transactions as described below. The unaudited pro forma condensed consolidated balance sheet has been prepared as though the spin-off of Murphy Oil Corporation’s U.S. downstream subsidiary, Murphy Oil USA, Inc. (“Murphy USA”), the special dividend of $2.50 per share payable on December 3, 2012 (for a total dividend of approximately $500 million) and the $1 billion of stock buybacks each occurred on September 30, 2012. The unaudited pro forma condensed consolidated income statements have been prepared as though the separation of Murphy USA occurred on January 1, 2011. The following unaudited pro forma condensed consolidated financial statements should be read in conjunction with our historical financial statements and accompanying notes.

The pro forma adjustments are based on available information and assumptions management believes are factually supportable and for income statement purposes recurring in nature. The pro forma adjustments to reflect the separation of Murphy USA include:

• a special distribution currently estimated at $250 million from Murphy USA to Murphy Oil Corporation in connection with the separation;

• reclassification of any accounts receivable from and payable to Murphy USA previously eliminated in consolidation as third party accounts receivable and payable;

• costs incurred with the separation of Murphy USA; and

• reclassification of interest income and expense that was previously eliminated in consolidation.

In addition to the above listed pro forma adjustments, the unaudited condensed consolidated income statement for the year ended December 31, 2011 includes a column to remove the exploration and production operations in the United Kingdom that became discontinued operations in the third quarter of 2012. These U.K. exploration and production operations are already reflected as discontinued operations in the unaudited pro forma condensed consolidated income statement for the nine months ended September 30, 2012 and the unaudited pro forma condensed consolidated balance sheet at September 30, 2012.

No adjustments have been made for (1) the costs of operating after the separation of Murphy USA, (2) the potentially dilutive impact of changes to stock-based compensation resulting from any future separation or settlement agreements between Murphy Oil Corporation and Murphy USA, (3) the use of proceeds from the special cash distribution currently estimated at $250 million from Murphy USA to Murphy Oil Corporation and (4) any working capital adjustments to be determined after the separation of Murphy USA, because in each case the impact of such item is not factually supportable at this time.

The unaudited pro forma condensed consolidated financial statements are for illustrative purposes only, and do not reflect what our financial position and results of operations would have been had the separation of Murphy USA, the payment of the special dividend and the completion of the maximum $1 billion of stock buybacks occurred on the dates indicated and are not necessarily indicative of our future financial position and future results of operations.
