CALGARY, May 26, 2011 (Canada NewsWire via COMTEX) --

/THIS PRESS RELEASE IS NOT FOR DISSEMINATION IN UNITED STATES OR TO ANY UNITED STATES NEWS SERVICES/

IROC Energy Services Corp. ("IROC" or the "Corporation") (TSXV: ISC) announces an operational update and guidance with respect to revenues and EBITDAS for the first quarter of 2011. This update is being provided as a result of the significant increase in activity in our business in the first quarter of 2011 as compared to the prior year and prior quarter.

Operational Update

Eagle Well Servicing

<<
    -   Eagle Well Servicing rig utilization, as measured by IROC's internal
        methodology, was 78% for the first quarter of 2011, with 25,391 rig
        hours being recorded and 36 service rigs in service during the
        quarter.

    -   Subsequent to the end of the first quarter 2011, in May, 2011, the
        Corporation has placed one additional rig into service for a total
        operational service rig fleet of 37 rigs. In addition, five new
        service rigs are being built with delivery expected in the third and
        fourth quarters of 2011.

    -   The trend toward increased oil related activity continues to provide
        benefit for our service rig division. Current activity levels are
        estimated to be in excess of 75% levered to oil, with completion,
        work over and abandonment activity all providing continued strong
        demand for our services in the foreseeable future.

    -   Eagle Well Servicing was able to fully crew its assets through the
        first quarter of 2011, despite a very tight labour market across the
        service industry.

    -   Activity levels continue to be strong given robust demand driven by
        oil activity, the expansion of horizontal drilling technology
        applications to new areas in Western Canada, ongoing abandonment work
        and an increasing base of active wells requiring ongoing maintenance.

AERO Rental Services

<<
    -   With the increase in drilling and field service activity over the
        past three quarters, IROC's rental services division, AERO Rental
        Services, remains strong and continues to grow. Growth in AERO's
        business is driven by increased horizontal and SAGD drilling activity
        in Western Canada. With the acquisition of the rental assets of Trust
        Energy Services in the third quarter of 2010, AERO's fracturing and
        coil tubing related business has also become an important part of our
        growth.

    -   AERO currently expects to add $7 million worth of rental inventory in
        2011, the majority of which will be purchased by the end of the
        second quarter.

2011 First Quarter Revenue and EBITDAS Guidance

IROC's interim unaudited financial statements and management's discussion and analysis ("MD&A") for the three months ended March 31, 2011 are scheduled to be released in June, 2011. This is later than normal due to the adoption of International Financial Reporting Standards.

The reader is cautioned that certain information contained in this release is forward looking and subject to adjustment due to the use of estimates and assumptions and additional information which may come to light prior to the release of the interim unaudited financial statements.

<<
    -   $12.6 million - for construction of six new service rigs in the Eagle
        Well Servicing division, with one rig being delivered during May, and
        one rig to be delivered in each of June, July, September, October and
        November, 2011. These rigs are utilizing in excess of $1.4 million of
        new fixed assets which were being held in inventory, for a total
        build cost of $14.0 million.

    -   $7 million - for expansion of rental inventory assets in the Aero
        Rental division.

Cautionary Statement Regarding Forward Looking Information and Statements

Certain information contained in this news release, including information related to the Corporation's level of service rig utilization, expected revenues, expected EBITDAS, timing of release of 2011 first quarter financial results, future capital expenditures, anticipated equipment counts and information or statements that contain words such as "forecasts", "could", "should", "can", "anticipate", "expect", "believe", "will", "may", "likely", "estimate", "predict", "potential", "continue", "maintain", "retain", "grow", and similar expressions and statements relating to matters that are not historical facts, and / or are under columns labelled "guidance", constitute "forward-looking information" within the meaning of applicable Canadian securities legislation. This information or these statements are based on certain assumptions and analysis made by the Corporation in light of its experience and its perception of historical trends, current conditions and expected future developments as well as other factors it believes are appropriate in the circumstances, and the statements contained in this news release speak only as of the date hereof.

Whether actual results, performance or achievements will conform to the Corporation's expectations and predictions is subject to a number of known and unknown risks and uncertainties which could cause actual results to differ materially from the Corporation's expectations. Such risks and uncertainties include, but are not limited to: fluctuations in the price and demand for oil and natural gas; fluctuations in the level of oil and natural gas exploration and development actives; fluctuations in the demand for well servicing and ancillary oilfield services; capital market liquidity available to fund oil and gas exploration and development programs; the effects of seasonal and weather conditions on operations and facilities; the highly competitive operating environment inherent in well servicing and ancillary oilfield services; general economic, market or business conditions; changes in laws or regulations; the availability of qualified operational and management personnel; currency exchange and interest rate fluctuations; uncertainties associated with regulatory approvals; uncertainty of government policy changes; uncertainties associated with credit facilities and counterparty credit risk; changes in income tax laws or changes in tax laws, crown royalty rates and incentive programs relating to the oil and gas industry; risks associated with government regulations and environmental health and safety matters; differences between Canadian GAPP and IFRS; and other unforeseen conditions which could impact the use of equipment and services supplied by IROC.

Non-GAAP Financial Measures

The financial statements, when released, will be prepared in accordance with GAAP. Certain supplementary information and measures not recognized under GAAP are provided where Management believes they assist the reader in understanding IROC's results.

EBITDAS is defined as earnings before interest, taxes, depreciation and amortization, stock-based compensation expense, foreign exchange gains and losses, goodwill impairment, note receivable impairment, and gains or losses on disposal of property and equipment. EBITDAS are not recognized measures under GAAP. The Corporation believes that EBITDAS provides a measure of operating performance without reference to financing decisions, income tax impacts and non-cash expenses, which are not controlled at the operating management level. Accordingly, the Corporation believes EBITDAS is a useful measure for prospective investors in evaluating the financial performance of the Corporation, and specifically, the ability of the Corporation to service the interest on its indebtedness and generate cash for re-investment. Investors should be cautioned that EBITDAS should not be construed as an alternative to net income determined in accordance with GAAP as an indicator of the Corporation's performance. IROC's method of calculating EBITDAS may differ from those of other companies, and accordingly, EBITDAS may not be directly comparable to measures used by other companies.

The Corporation is not providing net income guidance at this time and is therefore unable to reconcile EBITDAS guidance provided to net income.
