Exhibit 99.1

Global Hunter Securities GHS 100 Energy Conference June 26, 2013 Dick Alario Chairman, President and Chief Executive Officer

Safe Harbor Language This presentation and related commentary may contain "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. Any statements as to matters that are not of historic fact are forward-looking statements. These forward-looking statements are based on Key's current expectations, estimates and projections about Key, its industry, its management's beliefs and certain assumptions made by management, and include statements regarding future operational and activity expectations, anticipated financial performance in the second quarter of 2013, and expected financial contribution of rigs that are being redeployed due to the decline in customer activity in Mexico. No assurance can be given that such expectations, estimates or projections will prove to have been correct. Whenever possible, these "forward-looking statements" are identified by words such as "expects," "believes," "anticipates" and similar phrases. Readers and any audience are cautioned that any such forward-looking statements are not guarantees of future performance and are subject to certain risks, uncertainties and assumptions that are difficult to predict, including, but not limited to: risks that Key will be unable to achieve its financial, capital expenditure and operational projections, including quarterly projections of revenue and risks that Key's expectations regarding future activity levels, customer demand, and pricing stability may not materialize (whether for Key as a whole or for geographic regions and/or business segments individually); risks that fundamentals in the U.S. oil and gas markets may not yield anticipated future growth in Key's businesses, or could further deteriorate or worsen from the recent market declines, and/or that Key could experience further unexpected declines in activity and demand for its rig service, fluid management service, coiled tubing service, and fishing and rental service businesses; risks associated with the restructuring of Key's Fluid Management Services business; risks relating to Key's ability to implement technological developments and enhancements; risks relating to compliance with environmental, health and safety laws and regulations, as well as actions by governmental and regulatory authorities; risks affecting Key's international operations, including customer activity declines in Mexico and Key's understanding of such customer's spending plans; risks that Key may not be able to achieve its international growth and mobilization strategy in the foreign countries in which Key operates; risks that Key may be unable to achieve the benefits expected from acquisition and disposition transactions, and risks associated with integration of the acquired operations into Key's operations; risks, in responding to changing or declining market conditions, that Key may not be able to reduce, and could even experience increases in, the costs of labor, fuel, equipment and supplies employed and used in Key's businesses; risks relating to changes in the demand for or the price of oil and natural gas; risks that Key may not be able to execute its capital expenditure program and/or that any such capital expenditure investments, if made, will not generate adequate returns; and other risks affecting Key's ability to maintain or improve operations, including its ability to maintain prices for services under market pricing pressures, weather risks, and the impact of potential increases in general and administrative expenses. Because such statements involve risks and uncertainties, many of which are outside of Key's control, Key's actual results and performance may differ materially from the results expressed or implied by such forward-looking statements. Given these risks and uncertainties, readers are cautioned not to place undue reliance on such forward-looking statements. Other important risk factors that may affect Key's business, results of operations and financial position are discussed in its most recently filed Annual Report on Form 10-K, recent Quarterly Reports on Form 10-Q, recent Current Reports on Form 8-K and in other Securities and Exchange Commission filings. Unless otherwise required by law, Key also disclaims any obligation to update its view of any such risks or uncertainties or to announce publicly the result of any revisions to the forward-looking statements made here. However, readers should review carefully reports and documents that Key files periodically with the Securities and Exchange Commission. 2

U.S. Market Source: Smith Bits, 1/1/2009 through 3/29/2013. Drilling Rig Count Horizontal Rig Count Oil Markets (~85%) Gas Markets (~15%) Eagle Ford Bakken California Other Gas Haynesville Permian Other Oil ~10% ~5% ~15% ~25% ~45% Key's estimated 2013 1Q Revenue split by market 6

Growing Backlog of Potential Horizontal Well Interventions The secular growth in producing horizontal wells should lead to increased demand for Key's higher capability workover rigs and higher well intervention service intensity. 550 HP Rig with 116' Derrick and 425 HP Rig with 102' Derrick 7

U.S. Revenue Potential for Underutilized Assets We believe there is approximately 25% to 30% additional U.S. revenue potential if Key's existing service capacity were operating at effective full utilization levels of 90%. 8
