Announcement Call Presentation December 2019 Exhibit 99.3

Disclaimer Forward-looking statements This presentation contains “forward-looking statements” within the meaning of The Private Securities Litigation Reform Act of 1995. Forward-looking statements include, without limitation, statements regarding the estimated future financial performance, financial position and financial impacts of the Business Combination, the satisfaction of closing conditions to the Business Combination and the PIPE Investment, the level of redemption by GSAH’s public stockholders and purchase price adjustments in connection with the Business Combination, the timing of the completion of the Business Combination, the anticipated pro forma enterprise value and Adjusted EBITDA of the combined company following the Business Combination, anticipated ownership percentages of the combined company’s stockholders following the potential transaction, and the business strategy, plans and objectives of management for future operations, including as they relate to the potential Business Combination. Such statements can be identified by the fact that they do not relate strictly to historical or current facts. When used in this presentation, words such as “pro forma,” “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “might,” “plan,” “possible,” “potential,” “predict,” “project,” “should,” “strive,” “would” and similar expressions may identify forward-looking statements, but the absence of these words does not mean that a statement is not forward-looking. When GSAH discusses its strategies or plans, including as they relate to the Business Combination, it is making projections, forecasts and forward-looking statements. Such statements are based on the beliefs of, as well as assumptions made by and information currently available to, GSAH’s management. These forward-looking statements involve significant risk and uncertainties that could cause the actual results to differ materially from the expected results. Most of these factors are outside GSAH’s and Vertiv’s control and are difficult to predict. Factors that may cause such differences include, but are not limited to: (1) GSAH’s ability to complete the Business Combination or, if GSAH does not complete the Business Combination, any other initial business combination; (2) satisfaction or waiver (if applicable) of the conditions to the Business Combination, including with respect to the approval of the stockholders of GSAH; (3) the ability to maintain the listing of the combined company’s securities on the New York Stock Exchange; (4) the inability to complete the PIPE Investment; (5) the risk that the Business Combination disrupts current plans and operations of GSAH or Vertiv as a result of the announcement and consummation of the transaction described herein; (6) the ability to recognize the anticipated benefits of the Business Combination, which may be affected by, among other things, competition, the ability of the combined company to grow and manage growth profitably, maintain relationships with customers and suppliers and retain its management and key employees; (7) costs related to the Business Combination; (8) changes in applicable laws or regulations and delays in obtaining, adverse conditions contained in, or the inability to obtain necessary regulatory approvals required to complete the Business Combination; (9) the possibility that Vertiv and GSAH may be adversely affected by other economic, business, and/or competitive factors; (10) the outcome of any legal proceedings that may be instituted against GSAH, Vertiv or any of their respective directors or officers following the announcement of the Business Combination; (11) the failure to realize anticipated pro forma results and underlying assumptions, including with respect to estimated stockholder redemptions and purchase price and other adjustments; and (12) other risks and uncertainties indicated from time to time in the preliminary proxy statement of GSAH related to the Business Combination, including those under “Risk Factors” therein, and other documents filed or to be filed with the Securities and Exchange Commission (“SEC”) by GSAH. You are cautioned not to place undue reliance upon any forward-looking statements. Forward-looking statements included in this presentation speak only as of the date of this presentation. Neither GSAH nor Vertiv undertakes any obligation to update its forward-looking statements to reflect events or circumstances after the date hereof. Additional risks and uncertainties are identified and discussed in GSAH’s reports filed with the SEC and available at the SEC’s website at www.sec.ov. This investor presentation (the “presentation”) is for informational purposes only and does not constitute an offer to sell, a solicitation of an offer to buy, or a recommendation to purchase any equity, debt or other financial instruments of GS Acquisition Holdings Corp (“GSAH”) or Vertiv Holdings, LLC (“Vertiv”) or any of their respective affiliates. The presentation has been prepared to assist parties in making their own evaluation with respect to the proposed transactions (the “Business Combination”) contemplated by the Agreement and Plan of Merger (the “Merger Agreement”), by and among the GSAH, Crew Merger Sub I LLC, Crew Merger Sub II LLC, Vertiv and VPE Holdings, LLC and for no other purpose. It is not intended to form the basis of any investment decision or any other decisions with respect of the Business Combination. INVESTOR ROADSHOW No Representation or Warranty No representation or warranty, express or implied, is or will be given by GSAH or Vertiv or any of their respective affiliates, directors, officers, employees or advisers or any other person as to the accuracy or completeness of the information in this presentation or any other written, oral or other communications transmitted or otherwise made available to any party in the course of its evaluation of the Business Combination, and no responsibility or liability whatsoever is accepted for the accuracy or sufficiency thereof or for any errors, omissions or misstatements, negligent or otherwise, relating thereto. This presentation does not purport to contain all of the information that may be required to evaluate a possible investment decision with respect to GSAH, and does not constitute investment, tax or legal advice. The recipient also acknowledges and agrees that the information contained in this presentation is preliminary in nature and is subject to change, and any such changes may be material. GSAH and Vertiv disclaim any duty to update the information contained in this presentation. Any and all trademarks and trade names referred to in this presentation are the property of their respective owners. No Offer or Solicitation This presentation shall not constitute a solicitation of a proxy, consent or authorization with respect to any securities or in respect of the Business Combination. This presentation shall also not constitute an offer to sell or the solicitation of an offer to buy any securities pursuant to the Business Combination or otherwise, nor shall there be any sale of securities in any jurisdiction in which the offer, solicitation or sale would be unlawful prior to the registration or qualification under the securities laws of any such jurisdiction.

Disclaimer (Cont’d) Use of Projections This presentation contains financial forecasts. Neither GSAH’s nor Vertiv’s independent auditors have studied, reviewed, compiled or performed any procedures with respect to the projections for the purpose of their inclusion in this presentation, and accordingly, neither of them expressed an opinion or provided any other form of assurance with respect thereto for the purpose of this presentation. These projections are for illustrative purposes only and should not be relied upon as being necessarily indicative of future results. In this presentation, certain of the above-mentioned projected information has been provided for purposes of providing comparisons with historical data. The assumptions and estimates underlying the prospective financial information are inherently uncertain and are subject to a wide variety of significant business, economic and competitive risks and uncertainties that could cause actual results to differ materially from those contained in the prospective financial information. Projections are inherently uncertain due to a number of factors outside of GSAH’s or Vertiv’s control. Accordingly, there can be no assurance that the prospective results are indicative of future performance of GSAH, Vertiv or the combined company after the Business Combination or that actual results will not differ materially from those presented in the prospective financial information. Inclusion of the prospective financial information in this presentation should not be regarded as a representation by any person that the results contained in the prospective financial information will be achieved. Industry and Market Data In this presentation, we rely on and refer to information and statistics regarding market participants in the sectors in which Vertiv competes and other industry data. We obtained this information and statistics from third-party sources, including reports by market research firms and company filings. Being in receipt of the presentation you agree you may be restricted from dealing in (or encouraging others to deal in) price sensitive securities. Non-GAAP Financial Matters This presentation includes certain non-GAAP financial measures, including Adjusted EBITDA, Adjusted EBITDA Margin, Free Cash Flow and Free Cash Flow Conversion, Adjusted Revenue, and Adjusted Operating Income that are not prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and that may be different from non-GAAP financial measures used by other companies. GSAH and Vertiv believe that the use of these non-GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating results and trends. These non-GAAP measures with comparable names should not be considered in isolation from, or as an alternative to, financial measures determined in accordance with GAAP. See the footnotes on the slides where these measures are discussed and “Additional Financial Information” beginning on slide 38 of the Appendix for a description of these non-GAAP financial measures and reconciliations of such non-GAAP financial measures to the most comparable GAAP amounts. Additionally, to the extent that forward-looking non-GAAP financial measures are provided, they are presented on a non-GAAP basis without reconciliations of such forward-looking non-GAAP measures due to the inherent difficulty in forecasting and quantifying certain amounts that are necessary for such reconciliation. Other Transactions In the second half of 2018, Goldman Sachs and JPMorgan were retained by Vertiv to advise in connection with potential strategic alternatives including an initial public offering or sale. Vertiv ultimately decided to defer consideration of strategic alternatives to a later date. Additional Information GSAH intends to file with the SEC a preliminary proxy statement in connection with the Business Combination and will mail a definitive proxy statement and other relevant documents to its stockholders. The definitive proxy statement will contain important information about the Business Combination and the other matters to be voted upon at a meeting of stockholders to be held to approve the Business Combination and other matters (the “Special Meeting”) and is not intended to provide the basis for any investment decision or any other decision in respect of such matters. GSAH stockholders and other interested persons are advised to read, when available, the preliminary proxy statement, the amendments thereto, and the definitive proxy statement in connection with GSAH’s solicitation of proxies for the Special Meeting because the proxy statement will contain important information about the Business Combination. When available, the definitive proxy statement will be mailed to GSAH stockholders as of a record date to be established for voting on the Business Combination and the other matters to be voted upon at the Special Meeting. GSAH stockholders will also be able to obtain copies of the proxy statement, without charge, once available, at the SEC’s website at www.sec.gov or by directing a request to ir@Vertiv.com Participants in the Solicitation GSAH and its directors and officers may be deemed participants in the solicitation of proxies of GSAH stockholders in connection with the Business Combination. GSAH stockholders and other interested persons may obtain, without charge, more detailed information regarding the directors and officers of GSAH in GSAH’s Annual Report on Form 10-K for the fiscal year ended December 31, 2018, which was filed with the SEC on March 13, 2019. Information regarding the persons who may, under SEC rules, be deemed participants in the solicitation of proxies to GSAH stockholders in connection with the Business Combination and other matters to be voted upon at the Special Meeting will be set forth in the proxy statement for the Business Combination when available. Additional information regarding the interests of participants in the solicitation of proxies in connection with the Business Combination will be included in the proxy statement that the GSAH intends to file with the SEC.
