All statements other than statements of historical fact included or incorporated by reference in this presentation, including, among other things, statements regarding the proposed business combination transaction between DNOW Inc. (“DNOW”) and MRC Global Inc. (“MRC”), future events, plans and anticipated results of operations, business strategies, the anticipated benefits of the proposed transaction, the anticipated impact of the proposed transaction on the combined company’s business and future financial and operating results, the expected amount and timing of synergies from the proposed transaction, the anticipated closing date for the proposed transaction and other aspects of DNOW’s or MRC’s operations or operating results are forward-looking statements.

However, the absence of these words does not mean that the statements are not forward-looking. Where, in any forward-looking statement, DNOW or MRC expresses an expectation or belief as to future results, such expectation or belief is expressed in good faith and believed to be reasonable at the time such forward-looking statement is made. However, these statements are not guarantees of future performance and involve certain risks, uncertainties and other factors beyond DNOW’s or MRC’s control. Therefore, actual outcomes and results may differ materially from what is expressed or forecast in the forward-looking statements. The following important factors and uncertainties, among others, could cause actual results or events to differ materially from those described in forward-looking statements: DNOW’s ability to successfully integrate MRC’s businesses and technologies, which may result in the combined company not operating as effectively and efficiently as expected; the risk that the expected benefits and synergies of the proposed transaction may not be fully achieved in a timely manner, or at all; the risk that DNOW or MRC will be unable to retain and hire key personnel; the risk associated with each party’s ability to obtain the approval of its shareholders required to consummate the proposed transaction and the timing of the closing of the proposed transaction, including the risk that the conditions to the transaction are not satisfied on a timely basis or at all or the failure of the transaction to close for any other reason or to close on the anticipated terms, including the anticipated tax treatment; the risk that any regulatory approval, consent or authorization that may be required for the proposed transaction is not obtained or is obtained subject to conditions that are not anticipated; the occurrence of any event, change or other circumstance that could give rise to the termination of the proposed transaction; unanticipated difficulties, liabilities or expenditures relating to the transaction; the effect of the announcement, pendency or completion of the proposed transaction on the parties’ business relationships and business operations generally; the effect of the announcement or pendency of the proposed transaction on the parties’ common stock prices and uncertainty as to the long-term value of DNOW’s or MRC’s common stock; risks that the proposed transaction disrupts current plans and operations of DNOW or MRC and their respective management teams and potential difficulties in hiring or retaining employees as a result of the proposed transaction; rating agency actions and DNOW’s and MRC’s ability to access short- and long-term debt markets on a timely and affordable basis; changes in commodity prices, including a prolonged decline in these prices relative to historical or future expected levels; global and regional changes in the demand, supply, prices, differentials or other market conditions affecting oil and gas, including changes resulting from any ongoing military conflict, including the conflicts in Ukraine and the Middle East, and the global response to such conflict, security threats on facilities and infrastructure, or from a public health crisis or from the imposition or lifting of crude oil production quotas or other actions that might be imposed by Organization of Petroleum Exporting Countries and other producing countries and the resulting company or third-party actions in response to such changes; legislative and regulatory initiatives addressing global climate change or other environmental concerns; public health crises, including pandemics and epidemics and any impacts or related company or government policies or actions; investment in and development of competing or alternative energy sources; international monetary conditions and exchange rate fluctuations; changes in international trade relationships or governmental policies, including the imposition of price caps, or the imposition of trade restrictions or tariffs on any materials or products used in the operation of DNOW’s or MRC’s business, including any sanctions imposed as a result of any ongoing military conflict, including the conflicts in Ukraine and the Middle East; DNOW’s or MRC’s ability to collect payments when due; DNOW’s or MRC’s ability to complete any dispositions or acquisitions on time, if at all; the possibility that regulatory approvals for any dispositions or acquisitions will not be received on a timely basis, if at all, or that such approvals may require modification to the terms of those transactions or DNOW’s or MRC’s remaining businesses; business disruptions following any dispositions or acquisitions, including the diversion of management time and attention; potential liability for remedial actions under existing or future environmental regulations; potential liability resulting from pending or future litigation; the impact of competition and consolidation in the oil and natural gas industry; limited access to capital or insurance or significantly higher cost of capital or insurance related to illiquidity or uncertainty in the domestic or international financial markets or investor sentiment; general domestic and international economic and political conditions or developments, including as a result of any ongoing military conflict, including the conflicts in Ukraine and the Middle East; changes in fiscal regime or tax, environmental and other laws applicable to DNOW’s or MRC’s businesses; disruptions resulting from accidents, extraordinary weather events, civil unrest, political events, war, terrorism, cybersecurity threats or information technology failures, constraints or disruptions;

Use of Non-GAAP Financial Information and Other Terms This presentation contains certain financial measures that are not prepared in accordance with GAAP, including Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted EPS and net debt, as well as certain forward-looking projections that are not reconcilable with GAAP measures due to their inherent uncertainty. Due to the forward-looking nature of such measures used herein, management cannot reliably predict certain of the necessary components of the most directly comparable forward-looking GAAP measures. Accordingly, the Company is unable to present a quantitative reconciliation of such forward-looking non-GAAP financial measures to their most directly comparable forward-looking GAAP financial measures without unreasonable effort. Amounts excluded from these non-GAAP measures in future periods could be significant. Non-GAAP financial measures are not measurements of financial performance under GAAP and should not be alternatives to amounts presented in accordance with GAAP. DNOW and MRC view these non-GAAP financial measures as supplemental and they are not intended to be a substitute for, or superior to, the information provided by GAAP financial results.
