ANNOUNCES RESULTS FOR THE FOURTH QUARTER AND YEAR

ENDED DECEMBER 31, 2020

Tontitown, Arkansas, January 20, 2021......P.A.M. Transportation Services, Inc. (NASDAQ: PTSI) today reported net income of $14.0 million, or diluted and basic earnings per share of $2.43, for the quarter ended December 31, 2020 and net income of $17.8 million, or diluted earnings per share of $3.09 ($3.10 basic), for the year ended December 31, 2020. These results compare to net loss of $13.6 million, or diluted and basic loss per share of $2.37, for the quarter ended December 31, 2019 and net income of $7.9 million, or diluted earnings per share of $1.34 ($1.35 basic), for the year ended December 31, 2019. Net income and diluted earnings per share for the fourth quarter and year ended December 31, 2019 include the negative impact of estimated amounts reserved for the anticipated settlements of certain lawsuits, and each of the above periods for 2019 and 2020 includes unrealized non-cash gains and losses associated with the Company’s investments in marketable equity securities. Adjusted net income and adjusted diluted earnings per share reflecting the impact of the settlements and unrealized non-cash gains and losses are reported in the non-GAAP financial measures tables at the end of this release.

Operating revenues increased 15.6% to $142.8 million for the fourth quarter of 2020 compared to $123.5 million for the fourth quarter of 2019. The increase in operating revenues includes a 33.4% decrease in fuel surcharge revenue from $16.8 million for the fourth quarter of 2019 to $11.2 million for the fourth quarter of 2020 as average fuel prices were lower during the fourth quarter of 2020 compared to the fourth quarter of 2019. For the year ended December 31, 2020, operating revenues decreased 5.3% to $486.8 million compared to $514.2 million for the year ended December 31, 2019. The decrease in operating revenues includes a 35.9% decrease in fuel surcharge revenue from $74.7 million for the year ended 2019 to $47.8 million for the year ended 2020 as average fuel prices were lower during 2020 compared to 2019.

Joe Vitiritto, President of the Company, commented, “I am proud of our team and these results reflect the progress made during the fourth quarter with some of our pricing goals and our ability to sustain most of our cost savings initiatives implemented earlier in the year. These quarterly results represent a record quarter for us as it relates to revenue and operating income, so it is satisfying for our hardworking drivers, shop and office teams to experience record results this early into implementing our improvement processes. Another highlight, despite the COVID related setbacks experienced earlier in the year, our logistics division was able to achieve record revenue and operating results on a full-year basis.

Although we implemented steps that allowed us to make progress in the quarter, the challenging driver market continues to be one of our biggest areas of focus. We were able to grow our manned truck count in the 4th quarter, but the driver market remained tight and it was difficult to both acquire and retain driving professionals at the levels we expect.”

Non-GAAP Financial Measures

In addition to our results under United States generally accepted accounting principles (GAAP), this press release also includes non-GAAP financial measures termed adjusted net income and adjusted diluted earnings per share. The Company defines adjusted net income and adjusted diluted earnings per share as GAAP net income and GAAP diluted earnings per share, respectively, excluding certain significant items, such as expenses and reserves associated with certain litigation settlements and unrealized gains and losses on marketable equity securities, and any tax benefit associated with such items. Management believes that reporting adjusted net income and adjusted diluted earnings per share more clearly reflects the Company’s current operating results and provides investors with a better understanding of the Company’s overall financial performance. In addition, the adjusted results, although not a financial measure under GAAP, facilitate the ability to analyze the Company’s financial results in relation to those of its competitors and to the Company’s prior financial performance by excluding items which otherwise would distort the comparison. However, because not all companies use identical calculations, the Company's presentation of adjusted results may not be comparable to similarly titled measures of other companies. Adjusted net income and adjusted diluted earnings per share are not recognized terms under GAAP, do not purport to be alternatives to, and should be considered in addition to, and not as a substitute for or superior to, net income and diluted earnings per share, respectively, as defined under GAAP.

Pursuant to the requirements of Regulation G, we have provided a tabular reconciliation of GAAP net income to adjusted net income and GAAP diluted earnings per share to adjusted diluted earnings per share in this press release.
