| 58 | |     | -  2025 Proxy Statement |

| Annex A |     | Non-GAAP Financial Measures |

Certain financial information included in this proxy statement, as well as the letter to shareholders and annual report accompanying this proxy statement, are considered to be non-GAAPfinancial measures. Such measures, as further described below, may not be directly comparable to other similarly titled measures used by other companies and therefore may not be comparable among companies. Management believes these non-GAAPfinancial measures provide investors with useful supplemental information to evaluate the Company’s ongoing operations and to compare with past and future periods. Management also uses certain non-GAAPmeasures internally for forecasting, budgeting and measuring its operating performance. These measures should be viewed as supplementing, and not as an alternative or substitute for, the Company’s financial results prepared in accordance with GAAP. Pursuant to the requirements of Regulation G, Vertiv has provided reconciliations of non-GAAPfinancial measures to the most directly comparable GAAP financial measures. Vertiv’s non-GAAPfinancial measures include:

| • |     | Adjusted operating profit (loss), which represents operating profit (loss), adjusted to exclude amortization of intangibles; |

| • |     | Adjusted operating margin, which represents adjusted operating profit (loss) divided by net sales; |

| • |     | Organic net sales growth, which represents the change in net sales adjusted to exclude the impacts of foreign currency exchange rate; |

| • |     | Adjusted free cash flow, which represents net cash provided by (used for) operating activities adjusted to exclude capital expenditures and investments in capitalized software and to include proceeds from disposition of PP&E; and |

| • |     | Adjusted diluted EPS, which represents diluted earnings per share adjusted to exclude amortization of intangibles and change in warranty liability. |
