BAKER ANNOUNCES FINANCIAL RESULTS FOR THIRD QUARTER AND FIRST NINE MONTHS OF 2011

• Higher Net Income and EPS in Quarter on Slightly Lower Revenue

• Funded Backlog Up 6 Percent

PITTSBURGH — Michael Baker Corporation (NYSE Amex:BKR) today reported its financial results for the third quarter and first nine months of 2011.

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 $7.1 million, or $0.76 per diluted share, on total contract revenues of $131.1 million. This compares to net income from continuing operations of $5.0 million, or $0.54 per diluted share, on total contract revenues of $135.6 million in the third quarter of 2010. The period-over-period decrease in revenues was driven primarily by a decline in revenues in the Federal segment, resulting from decreases in work performed for the Company’s unconsolidated subsidiary in Iraq and a net decrease in work performed for FEMA, compared to the third quarter of 2010. The Transportation segment’s revenue also declined slightly during the quarter due to the wind down of three large design-build or program management projects, which was partially offset by increases in work performed on U.S. Highway 290 in Texas as well as construction management and inspection services related to roadways for Marcellus Shale drilling activity in Pennsylvania.

The increase in net income from continuing operations is attributable primarily to a 21 percent decrease in selling, general and administrative expenses compared to the third quarter of 2010, as well as the recovery of corporate indirect taxes and the Company’s ability to utilize foreign tax credits. Partially offsetting these benefits in the current period were the amortization of intangible assets related to recent acquisitions, severance costs related to the Company’s cost reduction programs, and acquisition and integration related costs.

Operating income from continuing operations in the third quarter of 2011 was $9.4 million, a 21 percent increase compared to the third quarter of 2010. This increase is attributable primarily to a net $1.2 million recovery of corporate indirect taxes and the aforementioned decrease in selling, general and administrative expenses.

Total backlog for continuing operations at September 30, 2011, was $1.52 billion, compared to $1.58 billion at December 31, 2010. Of these totals, $606 million and $570 million, respectively, are considered funded backlog, reflecting an increase of six percent for the nine-month period.

ADD ONE—BAKER FINANCIAL RESULTS FOR THIRD QUARTER 2011

On the balance sheet as of September 30, 2011, the Company had cash and investment balances of $96.4 million and no debt. Subsequent to this date, however, the Company entered into a Stock Purchase Agreement effective October 1, 2011, to acquire 100 percent of the outstanding shares of RBF Consulting for $49.3 million. This transaction was funded with $45.7 million of cash on hand and approximately $3.6 million of the Company’s stock.

For the first nine months of 2011, the Company reported income from continuing operations of $12.8 million, or $1.38 per diluted share, on total contract revenues of $382.2 million, compared with income from continuing operations of $15.2 million, or $1.67 per diluted share, on total contract revenues of $379.0 million in the first nine months of 2010.

The full-year forecasted effective income tax rate for continuing operations was 37.5 percent and 39.0 percent at September 30, 2011 and 2010, respectively.

Commenting on the results, President and Chief Executive Officer Bradley L. Mallory said, “We continue to be pleased with our performance in spite of an extremely difficult and uncertain business and funding environment. The steps we have taken during the year to bring our costs in line with declining revenue are beginning to take hold. While the fourth quarter is always challenging for us, we look forward to beginning the integration of RBF into the Baker family during this period, and we remain cautiously optimistic about our business prospects for 2012.”
