2023 Investor Day Presentation

Historical EBITDA and Adjusted EBITDA GAAP Reconciliations ($M) (cont'd) (1) In 2013, we retired all outstanding subordinated convertible debentures. (2) We have made a number of acquisitions in the past and may continue to make acquisitions in the future. Merger related costs only include costs associated with the major acquisitions that significantly impacted our operations (the "major acquisitions," each of which had annual revenues of over $200 million prior to acquisition). (3) Primarily reflects severance and branch closure charges associated with our restructuring programs. We only include such costs that are part of a restructuring program as restructuring charges. The designated restructuring programs generally involve the closure of a large number of branches over a short period of time, often in periods following a major acquisition, and result in significant costs that we would not normally incur absent a major acquisition or other triggering event that results in the initiation of a restructuring program. Since the first such restructuring program was initiated in 2008, we have completed six restructuring programs. In the first quarter of 2023, we initiated a restructuring program following the closing of the Ahern Rentals acquisition, which is our only open restructuring program as of March 31, 2023. We have cumulatively incurred total restructuring charges of $353 million under our restructuring programs. (4) Reflects additional costs recorded in cost of rental equipment sales associated with the fair value mark-up of rental equipment acquired in certain major acquisitions and subsequently sold. (5) Reflects a gain recognized upon the sale of a former subsidiary that developed and marketed software. (6) Represents non-cash, share-based payments associated with the granting of equity instruments. (7) In 2018, we adopted accounting guidance that addressed the cash flow presentation for proceeds from the settlement of insurance claims. Adoption of this guidance decreased net cash provided by operating activities, relative to previously reported amounts, but did not change EBITDA or adjusted EBITDA for 2017, 2016 and 2015 in the table above. The information required to determine the amount of insurance proceeds for periods prior to 2015 is unavailable without unreasonable effort. The insurance proceeds do not impact EBITDA or adjusted EBITDA. (8) The excess tax benefits from share-based payment arrangements result from stock-based compensation windfall deductions in excess of the amounts reported for financial reporting purposes. We adopted accounting guidance in 2017 that changed the cash flow presentation of excess tax benefits from share-based payment arrangements. In the table above, the excess tax benefits from share-based payment arrangements for periods after 2016 are presented as a component of net cash provided by operating activities, while, for 2015 and 2016, they are presented as a separate line item. ● United Rentals® Work United® 2023 Investor Day | 98
