“We were very gratified to see ArcBest post a first-quarter profit for the first time in seven years,” said ArcBest President and CEO Judy R. McReynolds. “As productivity and pricing improved, ABF Freight reversed last year’s first-quarter losses while maintaining its focus on better serving customers.  The emerging businesses contributed their largest revenue portion yet to ArcBest, at 29 percent of total consolidated revenue, as our efforts to provide tailored, customized solutions across the supply chain are resonating well.”

Results of Operations

First Quarter 2015

·                  Revenue of $441.2 million compared to $428.9 million in first quarter 2014, an increase of 2.9 percent

·                  Tonnage per day decrease of 0.5 percent versus first quarter 2014

·                  Total billed revenue per hundredweight of $28.06 compared to $27.05 the prior year, an increase of 3.7 percent

·                  Breakeven operating income compared to an operating loss of $12.2 million and an operating ratio of 102.8 percent in first quarter 2014

·                  Excluding adjustments for pension settlement charges, operating income of $0.9 million and operating ratio of 99.8 percent compared to an operating loss of $9.3 million and an operating ratio of 102.1 percent in first quarter 2014

·                  Though less of an effect than last year, results include a reduction in operating income associated with severe winter weather

ABF Freight experienced first quarter revenue growth on improved pricing despite the effects of a slight reduction in total freight tonnage.  By effectively managing its labor and equipment resources during the quarter, ABF Freight sought to maintain consistent service levels to both new and existing LTL customers.  Management focus has resulted in improved dock productivity as employees hired last year are more experienced in freight handling and loading.  Despite year-over-year reductions in fuel surcharge related to lower fuel prices, ABF Freight continued to experience positive account pricing through its traditional ability to focus on unique, customer-specific solutions.

Emerging, Non-Asset-Based Businesses

Results of Operations

First Quarter 2015

·                  Revenue of $183.7 million compared to $158.4 million in first quarter 2014, an increase of 16 percent

·                  These businesses equaled 29 percent of total consolidated revenue compared to 27 percent during the same period last year

·                  First quarter 2015 earnings before interest, taxes, depreciation and amortization (“EBITDA”) of $6.6 million compared to EBITDA in the first quarter of 2014 of $7.9 million, impacted by higher than expected healthcare and casualty claims

During the first quarter, ArcBest’s emerging, non-asset-based businesses continued to experience revenue growth highlighted by strong, double digit increases at ABF Logistics and ABF Moving.  ABF Logistics experienced significant growth in the freight brokerage business associated with additional shipments from new and existing customers and the expanding benefits of offering logistics services to customers across the ArcBest enterprise of companies.  As previously discussed, continued investments in personnel and resources needed to drive future growth are not yet fully contributing at margin levels expected when the business matures.

Compared to strong revenue growth last year, Panther had a moderate first quarter revenue increase on 16 percent growth in shipments, primarily driven by new customers.  Gross profit margins were impacted by demand softness and lower rates in the expedited market resulting from more readily available truckload capacity versus last year, and a shorter length of haul on new Panther business.  The quarter’s results were impacted by unfavorable experience in casualty claims and higher than expected healthcare costs, which in total increased Panther’s operating costs versus the same period last year by $1.5 million. Finally, costs associated with investments in additional sales personnel and infrastructure for future business growth also reduced first quarter 2015 profitability.

Non-GAAP Financial Measures. The Company reports its financial results in accordance with generally accepted accounting principles (“GAAP”). However, management believes that certain non-GAAP performance measures and ratios utilized for internal analysis provide financial statement users meaningful comparisons between current and prior period results, as well as important information regarding performance trends. Certain information discussed in the scheduled conference call could be considered non-GAAP measures. Non-GAAP financial measures should be viewed in addition to, and not as an alternative for, the Company’s reported results. Management believes EBITDA and Adjusted EBITDA to be relevant and useful information as EBITDA is a standard measure commonly reported and widely used by analysts, investors and others to measure financial performance and ability to service debt obligations. However, these financial measures should not be construed as better measurements than operating income, operating cash flow, net income or earnings per share, as defined by generally accepted accounting principles. Other companies may calculate EBITDA differently, and therefore the Company’s EBITDA and Adjusted EBITDA may not be comparable to similarly titled measures of other companies.
