BAKER REPORTS SECOND QUARTER 2012 FINANCIAL RESULTS

PITTSBURGH — Michael Baker Corporation (NYSE MKT:BKR) today announced its financial results for the second quarter of 2012.

Unless noted otherwise, 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. Included in continuing operations are the financial results of RBF Consulting (RBF), which Baker acquired effective October 1, 2011.

For the quarter, Baker reported net income from continuing operations of $2.7 million, or $0.28 per diluted share, on revenues of $155.3 million, compared to net income from continuing operations of $5.0 million, or $0.53 per diluted share, on revenues of $130.1 million in the second quarter of 2011.

The increase in second-quarter 2012 revenue compared to the year-ago period was driven primarily by the addition of $24.4 million in revenues from RBF and increases in certain key Transportation segment projects, all of which was partially offset by a decrease in work performed for FEMA.

Operating income from continuing operations for the second quarter of 2012 was $3.2 million, compared to $7.9 million for the same period in 2011. The decrease was attributable primarily to reduced gross profit of $1.9 million, as well as an increase in selling, general and administrative (SG&A) expenses of $2.8 million. Gross profit decreased mainly due to decreased utilization of personnel, an unfavorable project mix, and an increase in amortization expenses related to the Company’s recent acquisitions, partially offset by the addition of RBF’s gross profit.

SG&A expenses totaled $22.3 million for the second quarter of 2012, compared to $19.5 million in the year-ago period. This increase resulted primarily from additional SG&A expenses of $3.7 million from RBF, including $0.2 million of intangible asset amortization, which was partially offset by a period-over-period decrease in SG&A personnel, excluding the impact of RBF.

For the first six months of 2012, the Company recorded net income from continuing operations of $3.6 million, or $0.38 per diluted common share, on revenues of $307.0 million, compared with net income from continuing operations of $5.7 million, or $0.61 per diluted common share, on revenues of $251.1 million for the first half of 2011.

The Company’s full-year forecasted effective income tax rate from continuing operations was 40.5 percent and 39.5 percent as of July 1, 2012, and June 30, 2011, respectively.

Total backlog at July 1, 2012, was $1.61 billion, compared to $1.59 billion at December 31, 2011. Of these totals, $652 million and $685 million, respectively, are considered funded backlog.
