USA Truck Reports Third Quarter 2016 Results

3Q16 EPS of ($0.09) Narrowed Compared to ($0.15) for 2Q16

Operating Income for 3Q16 Improved $0.6 Million from 2Q16 $0.6 Million Operating Loss

Improvements in Trucking Segment Offset by Weak Freight Environment

Moves Forward in Expanding USAT Logistics’ Scope and Offerings

Van Buren, AR – November 4, 2016 – USA Truck, Inc. (NASDAQ: USAK), a leading capacity solutions provider, today announced its financial results for the three and nine months ended September 30, 2016.

For the quarter ended September 30, 2016, operating revenue was $105.5 million compared to $123.5 million for the prior-year period. Base revenue, which excludes fuel surcharges, was $94.7 million compared to $109.8 million for the 2015 period. Net income (loss) was ($0.7) million, or ($0.09) per diluted share, compared to $2.7 million, or $0.26 per diluted share, a year earlier. Included in earnings per share for the September 30, 2015 quarter was $2.9 million, or $0.17, net-of-tax, per share of restructuring costs.

President and CEO Randy Rogers commented, “We marked significant progress toward our goals of expanding the scope of USAT Logistics, improving service levels in our truckload business and reducing operating costs in the third quarter. Those gains were, and for the near term will likely be, offset by a weak freight environment and unfavorable comparisons versus prior periods due to the loss of certain dedicated account customers earlier this year. While encouraged by our progress, we recognize our results have not reached our goals and are committed to achieving substantial improvements in profitability as we move into the 2017 bid season and benefit from the extensive operating changes made over the past year.

“As previously discussed, one of our principal goals is for our higher margin, asset-light brokerage operations to contribute 50% of the company’s consolidated revenue. In support of this objective, during the quarter we expanded its sales channels to include agents in secondary markets and since have consolidated operations from smaller, inefficient offices into our larger regional centers while maintaining existing client manager relationships. We also completed the migration to a more efficient operating model featuring carrier and customer specialization, which has already begun to benefit productivity and effectiveness. While net revenue for the quarter of $6.0 million represented a 16.1% decline versus the 2015 period due to a soft freight environment and lower volumes, gross margin remained favorable at 18.1%.

“In Trucking, we achieved modest improvement in loaded rate per mile to $1.725 despite the difficult rate environment and posted a 4.3% decrease in operating expenses on a sequential basis, bringing O&M expenses per mile down to $0.182, the lowest in over four years. Further, in light of market conditions, we reduced company-owned tractors by 6.3% through the elimination of our 2012 and 30% of our 2013 tractors, which were high cost, challenging for our drivers and placed significant burdens on our maintenance operations. On a sequential basis, Trucking’s adjusted operating ratio improved slightly from 103.0% for this year’s second quarter as the operating loss narrowed from $2.0 million to $1.5 million, reflecting the benefits of our improvement plan in a tough environment.

“Cost reduction remains a critical focus area. In the third quarter, we completed and executed a thorough maintenance review, identifying internal and external cost reduction opportunities that for the quarter produced an 18% decrease in maintenance cost per mile. Key initiatives included the insourcing of our road assistance program from an outside vendor, negotiations with third-party vendors to leverage spend on parts and tires, retirement of higher cost tractors, and further downsizing of the trailer fleet as well as continued general expense controls.”

Mr. Rogers concluded, “As we move into the 2017 bid season, we expect our improved service performance and more focused network to drive meaningful rate improvement. We have identified pricing and utilization opportunities throughout our network and expect our enhanced support programs and more efficient and aligned compensation structures to increase the number of independent contractors and help offset the phase-out of our older tractor fleet. We are confident that our planned transition to an increasingly asset-light model is the right one for our organization and we expect to achieve positive earnings per share for the full year 2017.”

For the nine months ended September 30, 2016, operating revenue was $326.0 million compared to $390.0 million for the prior-year period. Consolidated base revenue was $296.2 million compared to $342.4 million for the nine months ended September 30, 2015. Consolidated net income (loss) was ($3.9) million, or ($0.44) per diluted share, for the 2016 period, compared to $7.1 million, or $0.68 per diluted share, for the 2015 period. Included in loss per diluted share for the nine months ended September 30, 2016 was $6.0 million, or $0.42, net-of-tax, per diluted share relating to restructuring, impairment and other costs. Included in earnings per share for the nine months ended September 30, 2015 was $0.8 million, or $0.04, net-of-tax, per diluted share relating to loss on extinguishment of debt and $2.9 million, or $0.17, net-of-tax, per share of restructuring costs.

^(a) About Non-GAAP Financial Information

In addition to our GAAP results, this press release also includes certain non-GAAP financial measures, as defined by the SEC. The terms base revenue, “EBITDA”, “Adjusted EBITDA”, “Adjusted operating ratio”, and “Adjusted earnings per diluted share”, as we define them, are not presented in accordance with GAAP.

The Company defines EBITDA as net income (loss), plus interest expense net of interest income, provision for income taxes and depreciation and amortization. It defines Adjusted EBITDA as these items plus non-cash equity compensation, loss on extinguishment of debt, restructuring, impairment and other costs, and severance costs included in salaries, wages and employee benefits. Adjusted operating ratio is calculated as operating expenses less restructuring, impairment and other costs and severance costs included in salaries, wages and employee benefits, net of fuel surcharges, as a percentage of operating revenue excluding fuel surcharge revenue. Adjusted earnings per diluted share is defined as earnings or loss before income taxes plus loss on extinguishment of debt, restructuring, impairment and other costs, and severance costs included in salaries, wages and employee benefits reduced by our statutory income tax rate, divided by weighted average diluted shares outstanding. These financial measures supplement our GAAP results in evaluating certain aspects of our business. We believe that using these measures improves comparability in analyzing our performance because they remove the impact of items from our operating results that, in our opinion, do not reflect our core operating performance. Management and the board of directors focus on EBITDA, Adjusted EBITDA, Adjusted operating ratio and Adjusted earnings per diluted share as key measures of our performance, all of which are reconciled to the most comparable GAAP financial measures and further discussed below. We believe our presentation of these non-GAAP financial measures is useful because it provides investors and securities analysts the same information that we use internally for purposes of assessing our core operating performance.

EBITDA, Adjusted EBITDA, Adjusted operating ratio and Adjusted earnings per diluted share are not substitutes for their comparable GAAP financial measures, such as net income, cash flows from operating activities, operating margin, or other measures prescribed by GAAP. There are limitations to using non-GAAP financial measures. Although we believe that they improve comparability in analyzing our period to period performance, they could limit comparability to other companies in our industry if those companies define these measures differently. Because of these limitations, our non-GAAP financial measures should not be considered measures of income generated by our business or discretionary cash available to us to invest in the growth of our business. Management compensates for these limitations by primarily relying on GAAP results and using non-GAAP financial measures on a supplemental basis.

Pursuant to the requirements of Regulation G and Regulation S-K, we have provided reconciliations of EBITDA, Adjusted EBITDA, Adjusted earnings per diluted share and Adjusted operating ratio to GAAP financial measures at the end of this press release.
