Exhibit 99.1

BAKER ANNOUNCES 2011 FINANCIAL RESULTS

PITTSBURGH — Michael Baker Corporation (NYSE Amex:BKR) today reported its financial results for the fourth quarter and the full year of 2011.

The information and discussion contained in this news release pertains to Baker’s continuing operations, while the Company’s Form 10-K, which is being filed with the SEC concurrent with this announcement, presents a complete discussion of both continuing and discontinued operations. Included in continuing operations are the financial results of RBF Consulting, which Baker acquired effective October 1, 2011.

For 2011, Baker reported net income from continuing operations of $16.8 million, or $1.80 per diluted common share, on total contract revenues of $538.4 million. This compares to net income from continuing operations of $14.7 million, or $1.60 per diluted common share, on total contract revenues of $499.4 million in 2010. The eight percent increase in revenues is attributable to $25.3 million of revenues from RBF, as well as increases in other key Transportation segment projects. Transportation segment revenues increased $38.1 million, driven primarily by an increase in work performed on U.S. 290 in Texas, an increase in construction management and inspection services related to roadways for the Marcellus Shale drilling activities in Pennsylvania, and the addition of RBF’s transportation revenues. Federal segment revenues increased slightly compared to 2010, with increases related to the addition of RBF’s Federal revenues and work performed for the U.S. Army Corp of Engineers, which were offset by decreases in work performed for the Company’s unconsolidated joint venture operating in Iraq and work performed on contracts for FEMA.

The increase in net income from continuing operations is attributable primarily to a decrease in the Company’s provision for income taxes resulting from its utilization of foreign tax credits as well as an increase in margins in the Federal segment, which was positively impacted by the net recovery of corporate indirect taxes. Partially offsetting these benefits in the current period were the aforementioned decrease in work performed in Iraq and for FEMA, a decrease in equity income from unconsolidated subsidiaries and an increase in amortization expenses related to recent acquisitions.

Total backlog for continuing operations at December 31, 2011, was $1.59 billion, compared to $1.58 billion at December 31, 2010. Of these totals, $685 million and $570 million, respectively, are considered funded backlog.
