News Release

Weatherford Reports First Quarter Results
$0.10 per diluted share, before severance, exit and other adjustments

GENEVA, SWITZERLAND, April 21, 2011 — Weatherford International Ltd. (NYSE and SIX: WFT) today reported first quarter 2011 income of $78 million, or $0.10 per diluted share, excluding an after-tax loss of $18 million. On a GAAP basis, our net income for the first quarter of 2011 was $59 million, or $0.08 per diluted share. The excluded after-tax loss is comprised of the following items:

	•		$9 million after-tax charge incurred in connection with the termination of a corporate consulting contract;
	•		$8 million in after-tax severance; and
	•		$1 million for investigation costs.

First quarter diluted earnings per share reflect an increase of $0.07 over the first quarter of 2010 diluted earnings per share of $0.03, before charges. Sequentially, the company’s first quarter diluted earnings per share, before charges, were $0.06 lower than the fourth quarter of 2010.

First quarter revenues were $2,856 million, or 23 percent higher than the same period last year, and down two percent sequentially. North America revenues increased 53 percent compared to the first quarter of 2010 while international revenues were up four percent over the same period.

Segment operating income of $353 million improved 38 percent year-over-year but was down 17 percent sequentially. Margin performance was held back primarily due to political turmoil in the Middle East and North Africa, unfavorable weather conditions and an equity tax enacted in Colombia.

The company expects earnings per share before excluded items of approximately $0.15 to $0.17 in the second quarter of 2011.

North America

Revenue increased eight percent sequentially and 53 percent compared to the first quarter of 2010. Canadian activity was strong while colder winter temperatures subdued progress in the United States. Operating income of $284 million improved $22 million sequentially, and margins increased 20 basis points to 20.9 percent.

Middle East/North Africa/Asia

Revenue decreased $109 million sequentially, or 16 percent, as political disruptions in the Middle East and North Africa and challenging weather events in Australia and China took a heavy toll, accounting for approximately two-thirds of the drop. Operating income declined $38 million sequentially, on decrementals of 35 percent.

Europe/West Africa/FSU

Revenue declined $18 million, or three percent, sequentially but was up 12 percent compared to the first quarter of 2010. The winter effect in the North Sea, Russia and Caspian were primarily responsible for the decline. Operating income declined $27 million sequentially. Contributing

to the severe decrementals were increased employee-related costs, as well as higher fuel and transportation costs in Russia.

Latin America

Revenue decreased eight percent, or $36 million, on a sequential basis and declined four percent, or $17 million, compared to the first quarter of 2010. Mexico and Venezuela led the declines. Operating income fell $32 million sequentially. Approximately $16 million of the decline was due to the charge for the Colombia equity tax. Adjusting for this effect, decrementals were approximately 44 percent.

Net Debt

Net debt for the quarter increased $547 million primarily as a result of an increase in working capital of $365 million. The increase in working capital was largely driven by North America and Latin America.

Reclassifications and Non-GAAP

Non-GAAP performance measures and corresponding reconciliations to GAAP financial measures have been provided for meaningful comparisons between current results and results in prior operating periods.

We report our financial results in accordance with generally accepted accounting principles (GAAP). However, Weatherford’s management believes that certain non-GAAP performance measures and ratios may provide users of this financial information additional meaningful comparisons between current results and results in prior operating periods. One such non-GAAP financial measure we may present from time to time is operating income or income from continuing operations excluding certain charges or amounts. This adjusted income amount is not a measure of financial performance under GAAP. Accordingly, it should not be considered as a substitute for operating income, net income or other income data prepared in accordance with GAAP. See the table below for supplemental financial data and corresponding reconciliations to GAAP financial measures for the three months ended March 31, 2011, December 31, 2010, and March 31, 2010. Non-GAAP financial measures should be viewed in addition to, and not as an alternative for, the Company’s reported results prepared in accordance with GAAP.

“Net Debt” is debt less cash. Management believes that Net Debt provides useful information regarding the level of Weatherford indebtedness by reflecting cash that could be used to repay debt.

Working capital is defined as accounts receivable plus inventory less accounts payable.
