Important Disclosures
Industry and Marketing Data
Although all information and opinions expressed in this presentation, including market data and other statistical information (including estimates and projections relating to
addressable markets), were obtained from sources believed to be reliable and are included in good faith, NOG has not independently verified the information and makes no
representation or warranty, express or implied, as to its accuracy or completeness. Some data is also based on the good faith estimates of NOG, which are derived from its review of
internal sources as well as the independent sources described above. This presentation contains preliminary information only, is subject to change at any time and, is not, and should
not be assumed to be, complete or to constitute all the information necessary to adequately make an informed decision regarding your engagement with NOG. While NOG is not
aware of any misstatements regarding the industry and market data presented in this presentation, such data involve risks and uncertainties and are subject to change based on
various factors, including those factors discussed under "Forward Looking Statements" above. NOG has no intention and undertakes no obligation to update or revise any such
information or data, whether as a result of new information, future events or otherwise, except as required by law.
Non-GAAP Financial Measures
This presentation includes certain financial measures that are not calculated in accordance with U.S. generally accepted accounting principles ("GAAP"). These measures include (i)
EBITDA, (ii) Adjusted EBITDA, (iii) Net Debt, (iv) Return on Capital Employed ("ROCE"), (v) Recycle Ratio and (iv) Free Cash Flow. These non-GAAP financial measures are not
measures of financial performance prepared or presented in accordance with GAAP and may exclude items that are significant in understanding and assessing our financial results.
Therefore, these measures should not be considered in isolation, and users of any such information should not place undue reliance thereon. Please refer to the slides titled "Non-
GAAP Reconciliations: Adjusted EBITDA & Other," "Non-GAAP Reconciliations: ROCE & Recycle Ratio," "Non-GAAP Reconciliations: Free Cash Flow" under the Appendix to this
presentation for a reconciliation of these measures to the most directly comparable GAAP measures and NOG's definitions (which may be materially different than similarly titled
measures used by other companies) of these measures as well as certain additional information regarding these measures. NOG believes the presentation of these metrics may be
useful to investors because it supplements investors' understanding of its operating performance by providing information regarding its ongoing performance that excludes items it
believes do not directly affect its core operations. From time-to-time NOG provides forward-looking Free Cash Flow estimates or targets; however, NOG is unable to provide a
quantitative reconciliation of the forward-looking non-GAAP measure to its most directly comparable forward-looking GAAP measure because management cannot reliably quantify
certain of the necessary components of such forward-looking GAAP measure. The reconciling items in future periods could be significant.
