BAKER REPORTS FIRST QUARTER 2011 FINANCIAL RESULTS

     PITTSBURGH — Michael Baker Corporation (NYSE Amex:BKR) today announced its financial results for the first quarter of 2011.

     As reported previously, the Company acquired The LPA Group Inc. on May 3, 2010, and these financial results include LPA’s results for the reporting period. In addition, in 2009 the Company sold its former Energy business and, as a result of this disposition, the financial results of the former Energy segment have been reclassified as discontinued operations for all periods presented in the consolidated financial statements. The information and discussion contained in this news release pertains to Baker’s continuing operations, while the Company’s Form 10-Q, which is being filed with the SEC concurrent with this announcement, presents a complete discussion of both continuing and discontinued operations.

     For the quarter, Baker reported net income from continuing operations of $0.7 million, or $0.08 per diluted share, on revenues of $121.0 million, compared to net income from continuing operations of $4.6 million, or $0.52 per diluted share, on revenues of $111.7 million in the first quarter of 2010.

     The increase in first-quarter 2011 revenues resulted from a 38 percent increase in Transportation revenues, primarily driven by revenues from LPA, offset by a decrease in revenues from the Federal business segment. The decrease in Federal revenues is primarily attributable to declines of $5.5 million in work performed for our unconsolidated subsidiary operating in Iraq, $2.5 million in work performed for FEMA, and $4.0 million on other Federal segment contracts, all of which was partially offset by an increase of $1.9 million related to work performed for the NAVFAC-Atlantic Division.

     Operating income from continuing operations for the first quarter of 2011 was $1.4 million, compared to $6.9 million for the same period in 2010. The decrease was attributable to the decline in Federal segment revenues noted previously, an overall increase in selling, general and administrative expenses, driven primarily by the LPA acquisition, and amortization expenses for intangible assets related to the LPA acquisition.

     In response to this decline in operating income, as well as the budgetary uncertainty at all levels of government that is exerting downward pressure on the Company’s revenues, the Company in early April implemented a cost reduction program which included a reduction in force, a hiring freeze, and other cost savings initiatives. The Company expects restructuring charges related to severance payments and medical benefits provided to terminated employees to be approximately $1.7 million, which will be recognized as a one-time expense in the second quarter of 2011.

     The Company’s provision for income taxes was 37.5 percent at March 31, 2011 and 2010.

     Total backlog at March 31, 2011, was $1.54 billion, compared to $1.58 billion at December 31, 2010. Of these totals, $563 million and $570 million, respectively, are considered funded backlog.

     On the balance sheet as of March 31, 2011, the Company had cash and investment balances of $92.4 million and no debt.

     Commenting on the results, President and Chief Executive Officer Bradley L. Mallory, said: “While not totally unexpected, we are disappointed with our first quarter performance. Our local, state and federal government clients were and will remain hesitant to spend funds on new and existing projects as long as budget uncertainties prevail. We did, however, experience an increase in work in March and expect to see continued progress in the second quarter. That, along with the impact of our cost reduction program, should enable us to record gradual improvement for the remainder of the year.”
