USA Truck Reports Record Fourth Quarter and Full-Year 2015 Results

Van Buren, AR – February 2, 2016 – USA Truck, Inc. (NASDAQ: USAK), a leading capacity solutions provider headquartered in Van Buren, AR, today announced its financial results for the three months and year ended December 31, 2015.

Vice Chairman Tom Glaser commented, “Our fourth-quarter results reflect the progress we have made improving profitability in our Trucking operations. The many initiatives we implemented to reenergize our Trucking turnaround, combined with Trucking’s strengthened leadership and the refreshing of our fleet, have enabled us to accelerate the progress underway. Our improved fourth-quarter results, particularly the 260-basis-point improvement in Trucking’s year-over-year operating ratio, illustrate the significant operating leverage the Company can build on as we move into 2016.”

For the fourth quarter of 2015, operating revenue was $118.0 million compared to $150.1 million for the prior-year period, reflecting improved pricing offset by lower volume. Base revenue, which excludes fuel surcharges, was $106.5 million compared to $125.8 million for the same period in the prior year. For the fourth quarter of 2015, net income increased to $3.9 million, or $0.39 per diluted share, up from $3.6 million, or $0.34 per diluted share, for the 2014 quarter. On an adjusted basis, the Company achieved earnings per diluted share of $0.38^(a) for the 2015 fourth quarter, compared to $0.35^(a) for the 2014 period.

Mr. Glaser continued, “We continue to focus on improving service to our customers, creating network and other efficiencies, lowering costs, and finally, continuing to strengthen the management and board leadership and culture of USA Truck to realize our significant potential. With the recent addition of Randy Rogers – a proven executive in logistics and transportation management – as USA Truck’s President, CEO and director, we have taken another key step that we believe will further strengthen our strategy as a capacity solutions provider. This includes the expansion of SCS, our asset-light business, which we believe offers compelling growth potential. As in 2015, we will continue our focus on improving return on invested capital, our core performance measure.”

President and CEO Randy Rogers added, “I am pleased to have joined USA Truck at such a meaningful time in its history. It has been exciting to see first-hand in the past few weeks the dedication and enthusiasm of USA Truck’s team members, who have been pivotal in transforming the culture and making this a great place to work. The progress made in such a short period in our Trucking business under our new leadership team is impressive and I look forward to working closely with them to generate further improvements. Furthermore, I believe our asset light business is built on a strong, scalable platform and I am excited about the opportunity to leverage my experience in logistics as we position our asset light business strategically to accelerate significant growth and to further position USA Truck as a leading capacity solutions provider.”

Full-Year Results

For the year ended December 31, 2015, operating revenue was $507.9 million compared to $602.5 million for the prior-year period. Base revenue, which excludes fuel surcharges, was $449.0 million compared to $494.3 million for 2014. Net income increased to $11.1 million from $6.3 million for 2014. For the year ended December 31, 2015, earnings per diluted share increased to $1.06 from $0.60 for the same period in the prior year. Included in earnings per diluted share for 2015 was $0.75 million, or $0.04, net-of-tax, per diluted share loss related to debt extinguishment and $2.7 million, or $0.17, net-of-tax, per diluted share relating to restructuring, severance and related costs. Included in earnings per share for 2014 was $2.8 million, or $0.16, net-of-tax, per diluted share related to defense costs.

The following table includes key operating results and statistics by reportable segment (2014 has been recast to reflect the change in accounting principle for tires):

Balance Sheet and Liquidity

Executive Vice President and CFO Michael Borrows said, “During the quarter, we continued to support USA Truck’s operations through focused balance sheet management, which also included investing in ourselves through our share repurchase program authorized by the board. As of December 31, 2015, our total debt and capital lease obligations, net of cash, was $101.3 million and our stockholders’ equity was $93.8 million. Debt to Adjusted EBITDA^(a) declined year-over-year, to 1.6x compared with 1.9x as of December 31, 2014.

“Since the end of 2014, the Company's balance sheet debt and capital lease obligations, net of cash, decreased by $16.0 million, while the outstanding obligations of financing provided by operating leases increased by $20.9 million, locking in the benefits of a favorable leasing environment. As of December 31, 2015, we had $90.8 million of borrowing availability under our revolving line of credit.”

Stock Repurchase Program

During the fourth quarter of 2015, USA Truck repurchased 707,759 shares of common stock (7.3% of total shares outstanding) under its stock repurchase program at a weighted average price of $18.69 per share for an aggregate purchase price of $13.2 million. As of December 31, 2015, 953,738 shares (9.9% of total shares outstanding) were purchased, and on January 8, 2016, the Company had repurchased the full one million shares of common stock included in the repurchase program authorized in August 2015.

The Company’s board of directors recently authorized the repurchase of up to an additional two million shares of the Company’s common stock. Mr. Rogers remarked, “Driving greater value to our stockholders will continue to be an important element of our capital allocation philosophy as we look to create value both as a capacity solutions leader and through the strategic use of the Company’s balance sheet and strong liquidity position.”

Any share repurchases will be made using a variety of methods, which may include open market purchases, privately negotiated transactions or block trades, or any combination of such methods, in accordance with applicable trading and other securities laws and regulations. The authorization expires in February 2019 unless earlier terminated or extended by the board of directors. Repurchased shares will be held as treasury stock and may be used for reissuance under the Company’s Employee Stock Purchase Plan or the Company’s 2014 Omnibus Incentive Plan, or for general corporate purposes as the board of directors may determine. Share repurchases are permitted under the Company’s primary credit facility and other contractual arrangements, subject to customary conditions.

The specific number of shares the Company ultimately repurchases, and the actual timing and amount of share repurchases, will depend on market conditions and other factors, as well as the applicable requirements of federal securities law. In addition, the stock repurchase program may be suspended, extended or terminated by the Company at any time without prior notice, and the Company is not obligated to purchase a specific number of shares.

^(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 “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, 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 and defense costs incurred primarily in connection with the unsolicited proposal to acquire USA Truck and the restructuring, severance and related costs. Adjusted operating ratio is calculated as operating expenses less restructuring, severance and related costs, net of fuel surcharges, as a percentage of operating revenue excluding fuel surcharge revenue. Adjusted earnings per diluted share is defined as income before income taxes plus loss on extinguishment of debt, defense costs and restructuring, severance and related costs reduced by our normalized income taxes, 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, 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.
