RailAmerica, Inc. Reports First Quarter 2012 Results

First Quarter Highlights

JACKSONVILLE, FL, April 25, 2012 – RailAmerica, Inc. (NYSE: RA) today reported financial results for the quarter ended March 31, 2012. First quarter 2012 revenue increased 15% to $143.4 million from $124.9 million in the first quarter of 2011. Freight revenue increased 10% to $107.8 million with average revenue per car up 7% and carloads up 3%. Non-freight revenue increased 30% to $35.6 million.

RailAmerica President and Chief Executive Officer John Giles, said “Our positive momentum continues to build as reflected in our record first quarter revenue and operating income excluding 45G benefits and asset sales. On a comparable basis, operating income was up 57% as we leveraged strong revenue growth and productivity gains. During the quarter, we completed our senior notes tender / refinancing, which will reduce our interest expense sharply while providing additional financial flexibility.”

Giles continued, “We remain active in the corporate development area, closing on the Wellsboro & Corning and its affiliated transload operations, TransRail North America, investment in early April. We expect to close on the Marquette Railroad acquisition in May, and our pipeline of additional opportunities remains promising.”

RailAmerica reported a first quarter 2012 net loss of $40.2 million, or $0.80 per diluted share, including $51.9 million after tax, or $1.03 per diluted share, of refinancing charges. This compares to net income of $4.1 million, or $0.07 per diluted share in the first quarter of 2011. The Company had adjusted net income¹ of $13.0 million and $6.4 million for the first quarters of 2012 and 2011, respectively. Noteworthy items impacting the first quarters of 2012 and 2011 include:

Note: Effective tax rates of 39% and 37% for 2011 and 2012, respectively

The Company reported operating income of $31.9 million in the first quarter of 2012 compared to $24.2 million in the first quarter of 2011. First quarter 2011 and 2012 operating income and expenses were impacted by 45G credits, restricted stock amortization, severance, the asset life study and the styrene resolution, as discussed above. In addition, first quarter 2012 operating expenses reflect increased purchased services primarily to support engineering services growth. Labor costs were up mainly due to increased carloads. The increase in materials was due to higher levels of car repair activity and growth in engineering services. Operating income excluding the impact of 45G benefit, asset sales and impairments is shown below.

RECONCILIATION OF NON-GAAP FINANCIAL MEASURES TO GAAP MEASURES

Adjusted net income (loss) is a supplemental measure of profitability that is not calculated or presented in accordance with U.S. generally accepted accounting principles (“GAAP”). We use non-GAAP financial measures as a supplement to our GAAP results in order to provide a more complete understanding of the factors and trends affecting our business. However, Adjusted net income (loss) has limitations as an analytical tool. It is not a measurement of our profitability under GAAP and should not be considered as an alternative to Net income (loss) as a measure of profitability.

Adjusted net income (loss) assists us in measuring our performance and profitability of our operations without the impact of transaction costs related to debt and credit facility extinguishment, acquisitions, impairment of assets and swap termination.
