14 Q & A

15 ADDITIONAL INFORMATION RECONCILIATIONS OF GAAP TO NON-GAAP FINANCIAL MEASURES (Unaudited) Note: ArcBest Corporation reports its financial results in accordance with generally accepted accounting principles (“GAAP”). However, management believes that certain non-GAAP performance measures utilized for internal analysis provides analysts, investors, and others the same information that we use internally for purposes of assessing our core operating performance and provides meaningful comparisons between current and prior period results, as well as important information regarding performance trends. Accordingly, using these measures improves comparability in analyzing our performance because it removes the impact of items from operating results that, in management's opinion, do not reflect our core operating performance. Non-GAAP financial measures should be viewed in addition to, and not as an alternative for, our reported results. These financial measures should not be construed as better measurements than operating income, operating cash flow, net income or earnings per share, as determined under GAAP.

17 RECONCILIATIONS OF GAAP TO NON-GAAP FINANCIAL MEASURES (Unaudited) ASSET-BASED SEGMENT Operating Income 2016 3Q’21 TTM 3Q’20 3Q’21 ($ millions) Amounts on a GAAP basis (1) $ 37.4 98.0% $ 205.5 91.6% $ 36.6 93.5% $ 83.6 87.7% Restructuring charges, pre-tax (2) 1.2 (0.1) --- Innovative technology costs, pre-tax (3) 1.9 (0.1) 28.2 (1.2) 6.2 (1.1) 6.9 (1.0) Non-GAAP amounts (4) $ 40.5 97.9% $ 233.8 90.4% $ 42.8 92.4% $ 90.5 86.7% 1) Operating Income for 2016 has been adjusted for the January 1, 2018, adoption of an amendment to ASC Topic 715 which requires the components of net periodic benefit cost other than service cost for our pension, SBP and postretirement plans to be presented within Other Income (Costs) in the consolidated financial statements and, therefore, excluded from Operating Income presented in this table. 2) Restructuring charges relate to the realignment of the Company’s organizational structure announced on November 3, 2016. 3) Costs associated with the freight handling pilot test program at ABF Freight announced in third quarter 2019. 4) Non-GAAP amounts are calculated in total and may not foot due to rounding.

18 RECONCILIATIONS OF GAAP TO NON-GAAP FINANCIAL MEASURES (Unaudited) ASSET-LIGHT ADJUSTED EBITDA (1) Three Months Ended September 30 2021 2020 Total Asset-Light ($ millions) Operating Income $ 11.5 $ 5.8 Depreciation and amortization 2.8 2.8 Adjusted EBITDA (2) $ 14.2 $ 8.6 CONSOLIDATED ADJUSTED EBITDAR (1) TTM Ended September 30, 2021 ($ millions) Net Income $ 171.9 Interest and other related financing costs 9.3 Income tax provision 49.2 Depreciation and amortization 121.3 Amortization of share-based compensation 11.1 Amortization of actuarial losses of benefit plans and pension settlement expense (0.6) Rent expense 24.9 Transaction costs 1.6 Consolidated Adjusted EBITDAR $ 388.7 1) Adjusted EBITDA and EBITDAR are primary components of the financial covenants contained in ArcBest Corporation's Amended and Restated Credit Agreement. Management believes Adjusted EBITDA and EBITDAR to be relevant and useful information, as EBITDA and EBITDAR are standard measures commonly reported and widely used by analysts, investors, and others to measure financial performance and ability to service debt obligations. Furthermore, management uses Adjusted EBITDA and EBITDAR as key measures of performance and for business planning. However, these non-GAAP financial measures should not be construed as better measurements than operating income, operating cash flow, net income, or earnings per share, as determined under GAAP. Non-GAAP financial measures should be viewed in addition to, and not as an alternative for, our reported results. Other companies may calculate EBITDA and EBITDAR differently; therefore, our Adjusted EBITDA and EBITDAR may not be comparable to similarly titled measures of other companies. 2) Adjusted EBITDA is calculated in total and may not foot due to rounding.
