FOR

SPECIAL ONE-TIME LONG-TERM INCENTIVE (LTI) AWARD

RESTRICTED STOCK UNIT AGREEMENT made in Columbus, Ohio, as of [DATE] (the “Grant Date”), between Vertiv Holdings Co (the “Company”) and [EMPLOYEE NAME] (“Participant”).

1.Grant of Award. The Company has granted you [NUMBER] Restricted Stock Units, subject to the provisions of this Agreement and the 2020 Stock Incentive Plan of Vertiv Holdings Co and its Affiliates (the “Plan”). The Company will hold the Restricted Stock Units and Additional Restricted Stock Units (as defined in Section 2) in a bookkeeping account on your behalf until they become payable or are forfeited or cancelled.

2.Dividend Equivalents. Except as otherwise determined by the Compensation Committee (the “Committee”), in its sole discretion, you will earn Dividend Equivalents in an amount equal to the value of any cash or stock dividends paid by the Company upon one Share of Common Stock for each unvested Restricted Stock Unit or Additional Restricted Stock Unit (as defined below) credited to your bookkeeping account on a dividend record date. In the case of cash dividends, the Company shall credit to your bookkeeping account, on each dividend payment date, an additional number of Restricted Stock Units (“Additional Restricted Stock Units”) equal to (a) divided by (b), where (a) equals the total number of unvested Restricted Stock Units and Additional Restricted Stock Units, if any, subject to this Agreement on such date multiplied by the dollar amount of the cash dividend paid per Share of Common Stock on such date, and (b) equals the Fair Market Value of a Share on such date. If a dividend is paid to holders of Common Stock in Shares, the Company shall credit to you, on each dividend payment date, Additional Restricted Stock Units equal to the total number of unvested Restricted Stock Units and Additional Restricted Stock Units subject to this Agreement on such date multiplied by the Share dividend paid per Share of Common Stock on such date. Additional Restricted Stock Units are subject to the same restrictions, including but not limited to vesting, transferability and payment restrictions, that apply to the Restricted Stock Units to which they relate.

3.Payment Amount. Each Restricted Stock Unit and Additional Restricted Stock Unit represents one (1) Share of Common Stock.

4.Vesting. Except as otherwise provided herein, the Restricted Stock Units and Additional Restricted Stock Units will vest in cumulative installments of 25% annually on each of the first, second, third and fourth anniversaries of the date of grant.

5.Form and Timing of Payment. Vested Restricted Stock Units will be redeemed solely for Shares. Except as otherwise determined by the Company, in its sole discretion, vested Additional Restricted Stock Units will be redeemed solely for Shares. Except as otherwise provided in Section 7(b) below, payment of vested Restricted Stock Units and Additional Restricted Stock Units will be made as soon as practicable following the applicable vesting date but in no event later than thirty (30) days following the vesting date.

6.Termination of Employment. Except as otherwise provided in this Agreement, any Restricted Stock Units and Additional Restricted Stock Units that have not vested as of your Termination of Employment will immediately be forfeited, and your rights with respect to these Restricted Stock Units and Additional Restricted Stock Units will end. If your Termination of Employment occurs due to an involuntary termination by the Company (other than for Cause), and such Termination of Employment occurs before the vesting date described in Section 4 of this Agreement, Restricted Stock Units and Additional Restricted Stock Units that have not vested as of the date of your Termination of Employment will vest on the scheduled dates specified in Section 4 occurring within six (6) months following your Termination of Employment.

7.Retirement, Death or Disability.

a.Vesting. If your Termination of Employment occurs due to death, or you incur a Disability before the vesting date described in Section 4 of this Agreement, all of your unvested Restricted Stock Units and Additional Restricted Stock Units will vest as of your Termination of Employment or Disability, as applicable.

If you are deceased, the Company will make a payment to your estate only after the Company has determined that the payee is the duly appointed executor or administrator of your estate, subject to Section 7.14 of the Plan. If your Termination of Employment occurs (other than for Cause) at a time when you (i) have attained age 65, and (ii) have ten (10) years of service with the Company (“Retirement”), and such Retirement occurs before the vesting date described in Section 4 of this

Exhibit 99.1

Agreement, all Restricted Stock Units and Additional Restricted Stock Units that have not vested as of the date of the Retirement will vest on the scheduled dates specified in Section 4.

b.Payment. If your Termination of Employment occurs due to death, Retirement or you incur a Disability before the vesting date described in Section 4 of this Agreement, payment for vested Restricted Stock Units and Additional Restricted Stock Units will be made as soon as practicable, but in no event later than thirty (30) days following the vesting date.

8.Company Policy. To the extent you are subject to the terms of the Vertiv Holdings Co Executive Change of Control Policy, you will enjoy the benefits provided for under the applicable Policy.

9.Withholdings; Delay for Specified Employees. The Company shall be entitled to require a cash payment by or on your behalf in respect of any sums required or permitted by federal, state or local tax law to be withheld with respect to the vesting of the Restricted Stock Units; provided, that, notwithstanding the foregoing, the Committee may permit you to satisfy the applicable tax obligations in accordance with the terms of Section 7.2 of the Plan. If you are a “specified employee” (within the meaning of Section 409A(2)(B) of the Code) as of the date of your separation from service (as determined pursuant to Section 409A of the Code), any portion of the Restricted Stock Units subject to Section 409A of the Code payable to you as a result of your separation from service within six (6) months following your separation from service shall instead be paid on the first business day of the first calendar month that begins after the six-month anniversary of the date of the separation from service, or, if earlier, the date of your death.

c.You further understand that part or all of your Data may be also held by the Company or its Affiliates, pursuant to a transfer made in the past with your consent, in respect of any previous grant of restricted units or awards, which was made for the same purposes of managing and administering of previous award/incentive plans, or for other purposes.

You waive any and all rights to compensation or damages as a result of the termination of employment with your local employer for any reason whatsoever insofar as those rights result, or may result, from the loss or diminution in value of such rights under the Plan or your ceasing to have any rights under, or ceasing to be entitled to any rights under, the Plan as a result of such termination.
