2011 Second Quarter Results

In discussing second quarter performance, Mark DiBlasi, President and CEO of Roadrunner, said,

“Strong performance across each of our business segments contributed to record quarterly operating income and earnings per share. Revenues increased 30.4% and net revenues expanded 46.8% from the prior year, resulting primarily from new customer growth, pricing initiatives, fuel increases, and the inclusion of our February 2011 acquisition of Morgan Southern. Excluding $1.5 million in IPO related costs that impacted our second quarter 2010 results, our operating income growth of 31.6% outpaced revenue growth despite the effects of higher fuel prices on revenues and operating costs.

LTL revenues increased $15.1 million, or 14.2%, from the prior year as the success of our yield and pricing initiatives drove an 11.3% improvement in revenue per hundredweight including fuel and 5.0% excluding fuel. New customer growth resulted in a tonnage increase of 2.7% over the prior year. Tonnage growth was flat mid-quarter as a result of sluggish freight demand, but rebounded slightly in the month of June to 4.6%. While we do not anticipate that overall economic conditions will improve significantly in the near term, we expect that our initiatives to penetrate new customers and expand into new geographic regions will continue to drive positive tonnage growth. Our LTL operating ratio improved sequentially to 93.7% in the second quarter from 95.2% in the first quarter, reflecting continued progress in mitigating the effects of rising truckload rates on linehaul costs. Excluding the impact of higher fuel costs on revenues and operating costs, our operating ratio in the second quarter of 2011 was equal with the prior year’s quarter, despite a 2.5% increase in linehaul cost per mile between the two quarters.

Truckload revenues grew by $31.1 million, or 82.7%, from the prior year. Revenues from Morgan Southern (acquired in early February) and Bruenger Trucking (acquired at the end of May) accounted for $19.5 million of the increase, with the balance of $11.6 million representing organic growth of 30.9%. The impact of these acquisitions and operating leverage associated with our revenue growth led to nearly a three-fold increase in our TL operating income and an improvement in our TL operating ratio to 93.8% from 96.1% in the second quarter of 2010.

For our TMS business, continued organic growth generated a $2.5 million, or a 15.2%, increase in revenues during the quarter and a 31.7% increase in operating income from the prior year. Operating income increased at a substantially greater rate as certain new customer growth was recorded on a net revenue basis since we did not take title to that freight.

Overall, our second quarter performance was very solid and we are optimistic about the opportunities we see for the balance of the year.”

2011 Second Quarter Segment Information

Roadrunner has three operating segments: less-than-truckload (LTL), truckload brokerage (TL) and transportation management solutions (TMS). The following highlights exclude intercompany eliminations and corporate expenses.

Our LTL revenues including fuel increased 14.2% to $121.4 million for the second quarter of 2011 from $106.3 million for the second quarter of 2010. LTL net revenues for the second quarter of 2011 were $29.4 million, or 24.2% of LTL revenues, compared to $26.8 million, or 25.2% of LTL revenues, for the second quarter of 2010. The decline in net revenue margin was a result of rising fuel prices while ongoing pricing initiatives more than offset a 2.5% increase in linehaul cost per mile from the second quarter of 2010. Collectively, the objective of our continuing yield and operating initiatives is to offset the impact of rising truckload rates on linehaul cost. LTL operating income was $7.7 million, or 6.3% of LTL revenues, for the second quarter of 2011 compared to $7.1 million, or 6.7% of revenues, for the second quarter of 2010.

Summary LTL operating statistics for the three and six months ended June 30 are shown below.

Note: Other than operating ratio, the statistics above do not include (i) adjustments for undelivered freight required for financial statement purposes in accordance with RRTS’ revenue recognition policy; and (ii) non-LTL related business captured within the LTL segment.

For the TL segment, revenues increased 82.7% to $68.7 million for the second quarter of 2011 from $37.6 million for the second quarter of 2010. The improvement was primarily due to increases in market pricing and load growth, the expansion of the company’s TL brokerage agent network, and the acquisitions of Morgan Southern and Bruenger Trucking. For the second quarter, Morgan Southern and Bruenger Trucking together contributed revenues of $19.5 million to the TL segment. Overall, TL net revenues for the second quarter of 2011 were $17.6 million, or 25.5% of TL revenues, compared to $4.3 million, or 11.4% of TL revenues, for the second quarter of 2010. TL operating income was $4.2 million, or 6.2% of TL revenues, for the second quarter of 2011 compared to $1.5 million, or 3.9% of revenues, for the second quarter of 2010.

For the TMS segment, revenues for the second quarter of 2011 increased 15.2% to $19.0 million from $16.5 million for the second quarter of 2010. TMS net revenues for the second quarter of 2011 were $4.9 million, or 25.8% of TMS revenues, compared to $4.3 million, or 25.9% of TMS revenues, for the second quarter of 2010. The improvement in TMS operating performance during the quarter was primarily attributable to new and existing customer growth. TMS operating income was $1.7 million, or 9.1% of TMS revenues, for the second quarter of 2011, compared to $1.3 million, or 7.9% of TMS revenues, for the second quarter of 2010.
