USA Truck Reports Third Quarter 2017 Results

Van Buren, AR – November 2, 2017 – USA Truck, Inc. (NASDAQ: USAK), a leading capacity solutions provider, today announced its financial results for the three and nine months ended September 30, 2017.

For the quarter ended September 30, 2017, consolidated operating revenue was $114.2 million compared to $105.5 million for the prior year period. Base revenue, which excludes fuel surcharge revenue, was $102.4 million compared to $94.7 million for the 2016 period. The Company reported net income of $0.4 million, or $0.05 per diluted share for the third quarter of 2017, compared to a net loss of ($0.7) million, or ($0.09) per diluted share, for the same quarter in 2016. The Company’s third quarter 2017 consolidated operating ratio was 98.4%, improved from 100.0% in the third quarter 2016.

President and CEO James Reed commented, “We believe these results show that we are capable of making and keeping our commitments to progress. I personally thank the whole team at USA Truck for their shared commitment to these results. We expect to improve results through disciplined network management and pricing, enhanced partnership with customers, and improved execution in our day-to-day operations, in conjunction with our ongoing safety initiatives. While we are pleased to report positive net income, it is important for all of us to recognize that the turnaround is still in its beginning stages and our expectations are for further improvement throughout 2018.”

Trucking: For the third quarter of 2017, Trucking operating revenue increased $3.1 million, or 4.2%, year-over-year, to $76.5 million, compared to third quarter of 2016.  This was primarily due to a 7.6% increase in base revenue per loaded mile, partially offset by a 4.2% decrease in loaded miles.  Trucking operating loss was ($1.2) million for the 2017 period compared to ($1.5) million for the 2016 period.  This loss was primarily driven by the combination of rising fuel costs throughout the quarter, elevated driver recruiting expenses, and underutilization of our tractors relative to desired levels; however, these headwinds were offset by our improving yield, as we continue to work on refining the network.

We remain intensely focused on improving Trucking operating results, and driving operational improvements with the goal of positioning us for long-term success. The following areas are specific areas of focus for our Trucking operations:

Drive gross margin of USAT Logistics: USAT Logistics operational performance continued to improve throughout 3Q17. Operating revenue was $37.8 million, up 17.7% versus 3Q16 and up 5.5% sequentially over 2Q17. Gross margin increased 130 basis points to 20.2% compared to 18.9% in 3Q16. USAT Logistics saw higher quarterly volumes when compared to the same period last year, driven primarily by increased spot market freight due to favorable movement in industry demand relative to capacity. While this market dynamic has been a positive one for USAT Logistics, we remain committed to our plan of building strong long-term customer relationships through superior service and competitive pricing.

Segment Results

The following table includes key operating results and statistics by reportable segment:

Balance Sheet and Liquidity

As of September 30, 2017, our total debt and capital lease obligations was $120.9 million, our total debt and capital lease obligations, net of cash (“Net Debt”), was $120.7 million and our stockholders’ equity was $51.5 million. Net Debt to Adjusted EBITDA^(a) decreased sequentially to 5.8x compared with 6.4x as of June 30, 2017. The Company had approximately $45.4 million available under its credit facility as of September 30, 2017. The Company anticipates a modest capital expenditure plan for the remainder of 2017; therefore, we expect free cash flow will be directed toward the repayment of debt.

^(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, “Net Debt”, “EBITDA”, “Adjusted EBITDA”, “Adjusted operating ratio”, and “Adjusted earnings (loss) per diluted share”, as we define them, are not presented in accordance with GAAP.

The Company defines Net Debt as total debt and capital lease obligations, net of cash. The Company defines EBITDA as net income (loss), plus interest expense net of interest income, provision for income tax expense (benefit) and depreciation and amortization. The Company defines Adjusted EBITDA as EBITDA plus non-cash equity compensation, impairments on assets held for sale, 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 surcharge revenue, as a percentage of operating revenue excluding fuel surcharge revenue. Adjusted earnings (loss) per diluted share is defined as net income (loss) per share plus the per share impact of restructuring, impairment and other, and severance costs included in salaries, wages and employee benefits, less the per share tax impact of those adjustments using a statutory income tax rate. The per share impact of each item is determined by dividing it by the 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 Net Debt, EBITDA, Adjusted EBITDA, Adjusted operating ratio and Adjusted earnings (loss) 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 to investors and other users because it provides them the same information that we use internally for purposes of assessing our core operating performance.

Net Debt, EBITDA, Adjusted EBITDA, Adjusted operating ratio and Adjusted earnings (loss) per diluted share are not substitutes for their comparable GAAP financial measures, such as net income, cash flows from operating activities, operating margin ratio, diluted earnings per share, 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 operating ratio and Adjusted earnings (loss) per diluted share to GAAP financial measures at the end of this press release.
