Item 8.01

Other Events.

As previously announced, on June 26, 2025, MRC Global Inc., a Delaware corporation (NYSE: MRC) (“MRC Global”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with DNOW Inc., a Delaware corporation (“DNOW”), Buck Merger Sub, Inc., a Delaware corporation and a wholly-owned, direct subsidiary of DNOW (“Merger Sub”), and Stag Merger Sub, LLC, a Delaware limited liability company and a wholly-owned, direct subsidiary of DNOW (“LLC Sub”), pursuant to which, upon the terms and subject to the conditions of the Merger Agreement, (1) Merger Sub will be merged with and into MRC Global (the “First Merger”), with MRC Global continuing as the surviving corporation in the First Merger, and (2) immediately following the First Merger, MRC Global will be merged with and into LLC Sub (the “Second Merger” and, together with the First Merger, the “Merger”), with LLC Sub continuing as the surviving company at the effective time of the Second Merger as a wholly-owned, direct subsidiary of DNOW.

On July 24, 2025, DNOW filed a registration statement on Form S-4 (No. 333-288909) (the “Registration Statement”), which contained a preliminary prospectus of DNOW and a preliminary joint proxy statement of DNOW and MRC Global. The Registration Statement was declared effective by the Securities and Exchange Commission (the “SEC”) on August 5, 2025. MRC Global filed with the SEC the definitive joint proxy statement/prospectus (the “joint proxy statement/prospectus” or the “Proxy Statement”) on August 5, 2025 and commenced mailing copies of the Proxy Statement on or about August 5, 2025.

Since entering into the Merger Agreement, MRC Global and/or DNOW have received, to MRC Global’s knowledge, several demand letters from purported shareholders of MRC Global (the “Demand Letters”) and three complaints with respect to the Merger have been filed. The complaints are captioned as follows: Robert Garfield v. Deborah Adams, Leonard Anthony, George Damiris, David Hager, Ronald Jadin, Anne McEntee, Robert Saltiel, Jr., Daniel Silvers, MRC Global Inc., DNOW Inc., J.P. Morgan Securities LLC, and Sodali & Co. Index No. 908471-25; Steven Weiss v. DNOW Inc., Richard Alario, Terry Bonno, David Cherechinsky, Galen Cobb, Paul Coppinger, Karen David-Green, Rodney Eads, and Sonya Reed Index No. 654945/2025; and Robert Scott v. DNOW Inc., Richard Alario, Terry Bonno, David Cherechinsky, Galen Cobb, Paul Coppinger, Karen David-Green, Rodney Eads, and Sonya Reed, Index No. 654962/2025 (collectively with the Demand Letters, the “Shareholder Actions”).

The Shareholder Actions assert that certain allegedly material omissions in the joint proxy statement/prospectus purportedly give rise to violations of Sections 14(a) and 20(a) of the Securities Exchange Act of 1934, as amended, and Rule 14a-9 promulgated thereunder. It is possible that additional or similar demand letters may be received by MRC Global or DNOW, or that complaints making similar allegations may be filed naming MRC Global or DNOW as a defendant, regarding the Merger. Absent new or different allegations that are material or a disclosure obligation under the U.S. federal securities laws, MRC Global will not necessarily disclose such additional demands or complaints.

MRC Global believes that the disclosures set forth in the joint proxy statement/prospectus comply fully with applicable law, that no further disclosure beyond that already contained in the joint proxy statement/prospectus is required under applicable law, and that the allegations asserted in the Shareholder Actions are entirely without merit. However, in order to moot these disclosure claims, to avoid nuisance, cost and distraction, and to preclude any efforts to delay the closing of the Merger, and without admitting any liability or wrongdoing, MRC Global is voluntarily supplementing the joint proxy statement/prospectus with the supplemental disclosures set forth below (the “Supplemental Disclosures”). Nothing in the Supplemental Disclosures shall be deemed an admission of the legal necessity or materiality under applicable laws of any of the disclosures set forth herein. To the contrary, Defendants specifically deny the allegations in the Shareholder Actions that any additional disclosure was or is required.

SUPPLEMENTAL DISCLOSURES TO JOINT PROXY STATEMENT/PROSPECTUS

The following supplemental information should be read in conjunction with the joint proxy statement/prospectus, which should be read in its entirety and is available on the SEC’s website at http://www.sec.gov, along with periodic reports and other information MRC Global files with the SEC. To the extent that the information set forth herein differs from or updates information contained in the joint proxy statement/prospectus, the information set forth

herein shall supersede or supplement the information in the joint proxy statement/prospectus. All page references are to pages in the joint proxy statement/prospectus, and terms used below, unless otherwise defined, have the meanings set forth in the joint proxy statement/prospectus. New text within restated language from the Proxy Statement is highlighted with bold, underlined text and removed language within restated language from the Proxy Statement is indicated by strikethrough text.

The third paragraph on page 95 of the Proxy Statement under the section entitled “Opinion of DNOW’s Financial Advisor — Illustrative Discounted Cash Flow Analysis” is hereby amended as follows:

Goldman Sachs derived a range of illustrative EVs for DNOW by adding the ranges of present values it derived above. Goldman Sachs then subtracted from the range of illustrative EVs it derived for DNOW the amount of DNOW’s net debt of approximately $(194) million and non-controlling interest of approximately $5 million, as provided by and approved for Goldman Sachs’ use by the management of DNOW, to derive a range of illustrative equity values for DNOW. Goldman Sachs then divided the range of illustrative equity values it derived by the number of fully diluted outstanding shares of DNOW of approximately 108.3 million, as provided by and approved for Goldman Sachs’ use by the management of DNOW, using the treasury stock method, to derive a range of illustrative present values per share ranging from $15.70 to $18.66.

The second paragraph on page 96 of the Proxy Statement under the section entitled “Opinion of DNOW’s Financial Advisor — Illustrative Discounted Cash Flow Analysis” is hereby amended as follows:

Goldman Sachs derived a range of illustrative EVs for MRC Global by adding the ranges of present values it derived above. Goldman Sachs then subtracted from the range of illustrative EVs it derived for MRC Global the amount of MRC Global’s net debt of approximately $324 million, as provided by and approved for Goldman Sachs’ use by the management of DNOW, to derive a range of illustrative equity values for MRC Global. Goldman Sachs then divided the range of illustrative equity values it derived by the number of fully diluted outstanding shares of MRC Global of approximately 87.7 million, as provided by and approved for Goldman Sachs’ use by the management of DNOW to derive a range of illustrative present values per share ranging from $15.60 to $19.39.

The fourth paragraph on page 96 of the Proxy Statement under the section entitled “Opinion of DNOW’s Financial Advisor — Illustrative Discounted Cash Flow Analysis” is hereby amended as follows:

Goldman Sachs derived a range of illustrative EVs for the pro forma combined company by adding the ranges of present values it derived above. Goldman Sachs then subtracted from the range of illustrative EVs it derived for the pro forma combined company the amount of the pro forma combined company’s net debt of approximately $230 million and non-controlling interest of approximately $5 million, as provided by and approved for Goldman Sachs’ use by the management of DNOW, to derive a range of illustrative equity values for the pro forma combined company. Goldman Sachs then divided the range of illustrative equity values it derived by the number of fully diluted outstanding shares of the pro forma combined company of approximately 191.5 million, as provided by and approved for Goldman Sachs’ use by the management of DNOW, using the treasury stock method, to derive a range of illustrative present values per share ranging from $17.15 to $20.92.

The second paragraph on page 97 of the Proxy Statement under the section entitled “Opinion of DNOW’s Financial Advisor — Illustrative Present Value of Future Share Price Analysis” is hereby amended as follows:

Goldman Sachs then subtracted the amount of DNOW’s net debt of approximately $(322) million for 2026 and $(338) million for 2027 and non-controlling interest of approximately $5 million for each of 2026 and 2027 for each of fiscal years 2026 and 2027, as provided by and approved for Goldman Sachs’ use by the management of DNOW, from the respective implied EVs in order to derive a range of illustrative equity values as of December 31 for DNOW for each of fiscal years 2026 and 2027. Goldman Sachs then divided these implied equity values by the projected year-end number of fully diluted outstanding shares of DNOW common stock for each of fiscal years 2026 and 2027 of approximately 103 million and 100 million, respectively, calculated using information provided by and approved for Goldman Sachs’ use by the management of DNOW, to derive a range of implied future values per share of DNOW common stock. Goldman Sachs then discounted these implied future equity values per share of DNOW common stock to March 31, 2025, using an illustrative discount rate of 11.0%, reflecting an estimate of DNOW’s cost of equity. Goldman Sachs derived such discount rate by application of the CAPM, which requires certain company-specific inputs, including a beta for DNOW, as well as certain financial metrics for the United States financial markets generally. This analysis resulted in a range of implied present values of $15.44 to $17.46 per share of DNOW common stock.

The fourth paragraph on page 97 of the Proxy Statement under the section entitled “Opinion of DNOW’s Financial Advisor — Illustrative Present Value of Future Share Price Analysis” is hereby amended as follows:

Goldman Sachs then subtracted the amount of MRC Global’s net debt of approximately $162 million and $37 million, respectively, for each of fiscal years 2026 and 2027, as provided by and approved for Goldman Sachs’ use by the management of DNOW, from the respective implied EVs in order to derive a range of illustrative equity values as of December 31 for MRC Global for each of fiscal years 2026 and 2027. Goldman Sachs divided these implied equity values by the projected year-end number of fully diluted outstanding shares of MRC Global common stock of approximately 88 million for each of fiscal years 2026 and 2027, calculated using information provided by and approved for Goldman Sachs’ use by the management of DNOW, to derive a range of implied future values per share of MRC Global common stock. Goldman Sachs then discounted these implied future equity values per share of MRC Global common stock to March 31, 2025, using an illustrative discount rate of 13.5%, reflecting an estimate of MRC Global’s cost of equity. Goldman Sachs derived such discount rate by application of the CAPM, which requires certain company-specific inputs, including a beta for MRC Global, as well as certain financial metrics for the United States financial markets generally. This analysis resulted in a range of implied present values of $13.66 to $16.78 per share of MRC Global common stock.

The second paragraph on page 98 of the Proxy Statement under the section entitled “Opinion of DNOW’s Financial Advisor — Illustrative Present Value of Future Share Price Analysis” is hereby amended as follows:

Goldman Sachs then subtracted the amount of the pro forma combined company’s net debt of approximately $(77) million for 2026 and $(250) million for 2027 and non-controlling interest of approximately $5 million for each of 2026 and 2027 for each of fiscal years 2026 and 2027, as provided by and approved for Goldman Sachs’ use by the management of DNOW, from the respective implied EVs in order to derive a range of illustrative equity values as of December 31 for the pro forma combined company for each of fiscal years 2026 and 2027. Goldman Sachs divided these implied equity values by the projected year-end number of fully diluted outstanding shares of the pro forma combined company’s common stock for each of fiscal years 2026 and 2027 of approximately 186 million and 183 million, respectively, calculated using information provided by and approved for Goldman Sachs’ use by the management of DNOW, to derive a range of implied future values per share of the pro forma combined company common stock. Goldman Sachs then discounted these implied future equity values per share of the pro forma company common stock to March 31, 2025, using an illustrative discount rate of 11.5%, reflecting an estimate of the pro forma combined company’s cost of equity. Goldman Sachs derived such discount rate by application of the CAPM, which requires certain company-specific inputs, including a beta for the pro forma combined company, as well as certain financial metrics for the United States financial markets generally. This analysis resulted in a range of implied present values of $15.97 to $19.75 per share of the pro forma combined company common stock.

The disclosure beginning on page 102 of the Proxy Statement under the section entitled “Opinion of MRC Global’s Financial Advisor—Public Trading Multiples” is hereby amended and restated in its entirety as follows:

Public Trading Multiples. Using publicly available information, J.P. Morgan compared selected financial data of each of MRC Global and DNOW with similar data for selected publicly traded companies engaged in businesses which J.P. Morgan judged to be sufficiently analogous to those engaged in by MRC Global and DNOW (or aspects thereof), as applicable.

The companies selected by J.P. Morgan with respect to MRC Global were as follows:

• DNOW

• DXP Enterprises, Inc.

• WESCO International, Inc.

• Rexel S.A.

The companies selected by J.P. Morgan with respect to DNOW were as follows:

• MRC Global

• DXP Enterprises, Inc.

• WESCO International, Inc.

• Rexel S.A.

J.P. Morgan selected these companies because, among other reasons, they are publicly traded companies with operations and businesses that, for the purposes of J.P. Morgan’s analysis, J.P. Morgan considered to be similar to those of MRC Global and DNOW, as applicable. However, certain of these companies may have characteristics that are materially different from those of MRC Global and DNOW, as applicable. The analyses necessarily involve complex considerations and judgments concerning differences in financial and operational characteristics of the companies involved and other factors that could affect the selected companies differently than they would affect MRC Global or DNOW, as applicable.

Using publicly available information, J.P. Morgan calculated, for each selected company,

(i)

the multiple of the firm value (calculated as equity value, plus or minus, as applicable, net debt or net cash, the “FV”) to the analyst consensus estimates of fiscal year 2025 adjusted EBITDA for the applicable company (the “FV/2025E Adj. EBITDA Multiple”) and

(ii)

the multiple of the FV to the analyst consensus estimates of fiscal year 2026 adjusted EBITDA for the applicable company (the “FV/2026E Adj. EBITDA Multiple”).

The companies selected by J.P. Morgan for its analyses, and the FV/2025E Adj. EBITDA Multiple and the FV/2026E Adj. EBITDA Multiple for each company, were as follows:


Company	FV/2025E Adj. EBITDA Multiple	FV/2026E Adj. EBITDA Multiple
MRC Global	7.3x	6.6x
DNOW	7.3x	7.0x
DXP Enterprises, Inc.	8.8x	8.1x
WESCO International, Inc.	9.4x	8.6x
Rexel S.A.	8.2x	7.8x

For MRC Global, based on the results of this analysis, J.P. Morgan selected

(i)

a FV/2025E Adj. EBITDA Multiple reference range of 7.00x to 9.25x and applied such reference range to MRC Global’s projected pre-SBC adjusted EBITDA for fiscal year 2025 and

(ii)

a FV/2026E Adj. EBITDA Multiple reference range for MRC Global of 6.50x to 8.50x and applied such reference range to MRC Global’s projected pre-SBC adjusted EBITDA for fiscal year 2026, in each case as provided in the MRC Global Projections for MRC Global.

The analysis derived the following ranges of implied equity value per share of MRC Global common stock (rounded to the nearest $0.10):


Metric	Implied Equity Value Per Share
Metric	Low	High
FV/2025E Pre-SBC Adj. EBITDA Multiple	$12.90	$18.30
FV/2026E Pre-SBC Adj. EBITDA Multiple	$12.80	$17.90

J.P. Morgan compared these ranges to:

(i)

the price per share of MRC Global common stock of $12.97 as of June 25, 2025; and

(ii)

the implied price per share of MRC Global common stock of $13.85 based on the exchange ratio.

For DNOW, based on the results of this analysis, J.P. Morgan selected

(i)

a FV/2025E Adj. EBITDA Multiple reference range of 7.00x to 9.25x and applied such reference range to DNOW’s projected pre-SBC adjusted EBITDA for fiscal year 2025 and

(ii)

a FV/2026E Adj. EBITDA Multiple reference range for DNOW of 6.50x to 8.50x and applied such reference range to DNOW’s projected pre-SBC adjusted EBITDA for fiscal year 2026, in each case as provided in the MRC Global Projections for DNOW. The analysis derived the following ranges of implied equity value per share of DNOW common stock (rounded to the nearest $0.10):


Metric	Implied Equity Value Per Share
Metric	Low	High
FV/2025E Pre-SBC Adj. EBITDA Multiple	$14.60	$18.70
FV/2026E Pre-SBC Adj. EBITDA Multiple	$14.60	$18.60

J.P. Morgan compared these ranges to the price per share of DNOW common stock of $14.60 as of June 25, 2025.

The first paragraph on page 104 of the Proxy Statement under the section entitled “Opinion of MRC Global’s Financial Advisor—Discounted Cash Flow Analysis” is hereby amended as follows:

J.P. Morgan then discounted the unlevered free cash flow estimates and the range of terminal values to present value as of June 30, 2025 using discount rates ranging from 8.50% to 10.50%, which range J.P. Morgan chose based upon an analysis of the weighted average cost of capital of each of MRC Global and DNOW. The present values of the unlevered free cash flow estimates and the range of terminal values were then adjusted for each of MRC Global’s and DNOW’s estimated net debt as of June 30, 2025, of $401 million and DNOW’s estimated net cash of $210 million, respectively, as provided in the MRC Global Projections for MRC Global and MRC Global Projections for DNOW in each case discounted to present value as of June 30, 2025 using a range of discount rates from 8.50% to 10.50%.

The disclosure under clause (ii) of the last paragraph beginning on page 104 of the Proxy Statement under the section entitled “Opinion of MRC Global’s Financial Advisor—Value Creation Analysis” is hereby amended as follows:

(ii)

subtracting certain other estimated total transaction expenses of MRC Global and DNOW of $75 million, as estimated by MRC Global management as of June 23, 2025 estimated and provided to J.P. Morgan for use in connection with its analysis; and

The disclosure on page 112 of the Proxy Statement under the section entitled “Interests of Certain MRC Global Directors and Executive Officers in the Mergers— New Management Arrangements” is hereby amended and restated in its entirety as follows:

As of the date of this joint proxy statement/prospectus, there are no other new employment, equity contribution or other agreements between any MRC Global executive officer or director, on the one hand, and MRC Global or DNOW, on the other hand have been established or otherwise negotiated, relating to employment, compensation or benefits of MRC Global’s executive officers following the consummation of the mergers. Prior to and following the closing of the mergers, however, certain of our executive officers may have discussions with, and may enter into agreements with, DNOW, the surviving corporation or their affiliates regarding employment with or providing consultation services to DNOW, the surviving corporation or their affiliates or the right to participate in the equity of the surviving corporation or one or more of its affiliates to be effective following the closing of the mergers.

However, the absence of these words does not mean that the statements are not forward-looking. Where, in any forward-looking statement, MRC Global or DNOW 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 MRC Global’s or DNOW’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 Global’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 MRC Global or DNOW 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 MRC Global’s or DNOW’s common stock; risks that the proposed transaction disrupts current plans and operations of MRC Global or DNOW and their respective management teams and potential difficulties in hiring or retaining employees as a result of the proposed transaction; rating agency actions and MRC Global’s and DNOW’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 MRC Global’s or DNOW’s business, including any sanctions imposed as a result of any ongoing military conflict, including the conflicts in Ukraine and the Middle East; MRC Global’s or DNOW’s ability to collect payments when due; MRC Global’s or DNOW’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 MRC Global’s or DNOW’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 MRC Global’s or DNOW’s businesses; disruptions resulting from accidents, extraordinary weather events, civil unrest, political events, war, terrorism, cybersecurity threats or information technology failures, constraints or disruptions; and other economic, business, competitive and/or regulatory factors affecting MRC Global’s or DNOW’s businesses generally as set forth in their filings with the Securities and Exchange Commission (the “SEC”).
