Non - GAAP Financial Measures : This Presentation includes certain financial measures not presented in accordance with generally accepted accounting principles (“GAAP”) including, but not limited to, EBITDA and certain ratios and other metrics derived therefrom . NESR believes that these non - GAAP measures of financial results provides useful information to management and investors regarding certain financial and business trends relating to NPS, GES and NESR’s financial condition and results of operations . NESR’s management uses these non - GAAP measures to compare its performance to that of prior periods for, among other reasons, trend analysis and for budgeting and planning purposes .

The principal limitation of these non - GAAP measures is that they exclude significant expenses that are required by GAAP to be recorded in the Company’s financial statements . In addition, these measures are subject to inherent limitations as they reflect the exercise of judgment by management about which expenses and income are excluded or included in determining these non - GAAP measures . You should not place undue reliance on these non - GAAP measures .
