Avis Budget Group Reports Record Revenues, Net Income and Adjusted EBITDA

February 14, 2022 at 4:05 PM EST

PARSIPPANY, N.J., Feb. 14, 2022 (GLOBE NEWSWIRE) -- Avis Budget Group, Inc. (NASDAQ: CAR) today announced financial results for fourth quarter and full year ended December 31, 2021.

We ended 2021 with fourth quarter revenues 90% above prior year and 19% above fourth quarter of 2019, at $2.6 billion. Our revenues were driven by increased revenue per day and rental days as demand continued from the third quarter. Net income was $381 million and Adjusted EBITDA was $683 million, our best fourth quarter Adjusted EBITDA in Company history. Utilization for the quarter was 68.2%, showing that our fleet was well positioned to meet demand.

Full year revenues increased 72% compared to the prior year and 2% above 2019, at $9.3 billion. Net income was $1.3 billion and Adjusted EBITDA was $2.4 billion, both new full year records for the Company. The significant increase in revenues suggests a steady return to historic travel levels.

Our liquidity position at the end of the quarter was approximately $757 million with an additional $2.6 billion of fleet funding capacity. We have well-laddered corporate debt and no meaningful maturities until 2024.

“Our strong performance continued in the fourth quarter with all of our key metrics beating pre-pandemic levels in the Americas,” said Joe Ferraro, Avis Budget Group Chief Executive Officer. “We were able to achieve these results and deliver the best year in our Company's history despite the emergence of Omicron. This wouldn't have been possible without the tireless effort of our entire organization and I want to thank the team for helping us achieve these milestones.”

Q4 and Full Year Highlights

  • Total Company revenues for the fourth quarter increased by 90% and 19% compared to fourth quarter 2020 and 2019, respectively.
  • Adjusted EBITDA in the Americas was $670 million for the fourth quarter and $2.4 billion for the year ended 2021 driven by strong pricing, increased demand and sustained cost discipline.
  • Adjusted EBITDA in International was $32 million for the fourth quarter and $118 million for the year ended 2021 driven by strong pricing, continued recovering volume and strong cost mitigating actions.
  • We repurchased approximately 2.6 million shares of common stock in the fourth quarter at an average cost of $170, bringing our total repurchases to approximately 14.3 million shares of common stock for 2021.

Certain statements in this press release constitute “forward-looking statements.” Any statements that refer to outlook, expectations or other characterizations of future events, circumstances or results, including all statements related to our future results, impact from the COVID-19 outbreak, future travel levels, cost-saving actions, the global semiconductor shortage and cash flows are forward-looking statements. Various risks that could cause future results to differ from those expressed by the forward-looking statements included in this press release include, but are not limited to, the severity and duration of the COVID-19 outbreak, which is expected to continue to have a significant impact on our operations, and resulting economic conditions and related restrictions, the high level of competition in the mobility industry, changes in our fleet costs, including as a result of a change in the cost of new vehicles, manufacturer recalls and/or the value of used vehicles, disruption in the supply of new vehicles, disposition of vehicles not covered by manufacturer repurchase programs, our ability to realize our estimated cost savings on a timely basis, or at all, the financial condition of the manufacturers that supply our rental vehicles, including as a result of the global semiconductor shortage, which could affect their ability to perform their obligations under our repurchase and/or guaranteed depreciation arrangements, the significant decline in travel demand as a result of COVID-19, including the current and any further disruptions in airline passenger traffic, the absence of an improvement in or any further deterioration in economic conditions generally, particularly during our peak season and/or in key market segments, any occurrence or threat of terrorism, the current and any future pandemic diseases or other natural disasters, any changes to the cost or supply of fuel, risks related to acquisitions or integration of acquired businesses, risks associated with litigation, including class action lawsuits, governmental or regulatory inquiries or investigations, risks related to the security of our information technology systems, disruptions in our communication networks, changes in tax or other regulations, a significant increase in interest rates or borrowing costs, our ability to obtain financing for our global operations, including the funding of our vehicle fleet via asset-backed securities markets, any fluctuations related to the mark-to-market of derivatives which hedge our exposure to exchange rates, interest rates and fuel costs, our ability to meet the covenants contained in the agreements governing our indebtedness, and our ability to accurately estimate our future results and implement our cost savings actions. Other unknown or unpredictable factors could also have material adverse effects on the Company’s performance or achievements. Important assumptions and other important factors that could cause actual results to differ materially from those in the forward-looking statements are specified in Avis Budget Group’s Annual Report on Form 10-K for the year ended December 31, 2020, Quarterly Report on Form 10-Q for the three and nine months ended September 30, 2021 and in other filings and furnishings made by the Company with the Securities and Exchange Commission (the "SEC") from time to time. The Company undertakes no obligation to publicly update any forward-looking statements to reflect subsequent events or circumstances.

Non-GAAP Financial Measures and Key Metrics

This release includes financial measures such as Adjusted EBITDA, Adjusted net income and Adjusted free cash flow, as well as other financial measures that are not considered generally accepted accounting principles (“GAAP”) measures as defined under SEC rules. Important information regarding such measures is contained in the financial tables to this release and in Appendix I, including the definitions of these measures and reconciliations to the closest comparable GAAP measures. The Company and its management believe that these non-GAAP measures are useful to investors in measuring the comparable results of the Company period-over-period. The GAAP measures most directly comparable to Adjusted EBITDA, Adjusted free cash flow, Adjusted pretax income (loss), Adjusted net income (loss) and Adjusted diluted earnings (loss) per share are net income (loss), net cash provided by operating activities, income (loss) before income taxes, net income (loss) attributable to Avis Budget Group, Inc. and diluted earnings (loss) per share, respectively. Foreign currency translation effects on the Company’s results are quantified by translating the current period’s non-U.S. dollar-denominated results using the currency exchange rates of the prior period of comparison including any related gains and losses on currency hedges. Per-unit fleet costs, which represent vehicle depreciation, lease charges and gain or loss on vehicle sales, divided by average rental fleet, are calculated on a per-month basis.

DEFINITIONS OF NON-GAAP MEASURES AND KEY METRICS

Adjusted EBITDA
The accompanying press release presents Adjusted EBITDA, which represents income (loss) from continuing operations before non-vehicle related depreciation and amortization, any impairment charges, restructuring and other related charges, early extinguishment of debt costs, non-vehicle related interest, transaction-related costs, net, charges for unprecedented personal-injury and other legal matters, net, which includes amounts recorded in excess of $5 million related to class action lawsuits, non-operational charges related to shareholder activist activity, which include third party advisory, legal and other professional service fees, gain on sale of equity method investment in China, COVID-19 charges and income taxes. COVID-19 charges include unusual, direct and incremental costs due to the COVID-19 pandemic, such as minimum annual guaranteed rent in excess of concession fees for the period, overflow parking for idle vehicles and related shuttling costs, incremental cleaning supplies to sanitize vehicles and facilities, and losses associated with vehicles damaged in overflow parking lots, net of insurance proceeds. We have revised our definition of Adjusted EBITDA to exclude amounts recorded in excess of $5 million related to class action lawsuits. We did not revise prior years’ Adjusted EBITDA because there were no costs similar in nature to these costs. Adjusted EBITDA includes stock-based compensation expense and deferred financing fee amortization totaling $11 million and $9 million in fourth quarter 2021 and 2020, respectively and totaling $52 million and $31 million in the year ended December 31, 2021 and 2020, respectively.

We believe that Adjusted EBITDA is useful to investors as a supplemental measure in evaluating the aggregate performance of our operating businesses and in comparing our results from period to period. Adjusted EBITDA is the measure that is used by our management, including our chief operating decision maker, to perform such evaluation. Adjusted EBITDA is also a component in the determination of management's compensation. Adjusted EBITDA should not be considered in isolation or as a substitute for net income or other income statement data prepared in accordance with GAAP and our presentation of Adjusted EBITDA may not be comparable to similarly-titled measures used by other companies. A reconciliation of Adjusted EBITDA from net income (loss) recognized under GAAP is provided on Table 5.

Adjusted Earnings Non-GAAP Measures
The accompanying press release and tables present Adjusted pretax income (loss), Adjusted net income (loss) and Adjusted diluted earnings (loss) per share, which exclude certain items. We believe that these measures referred to above are useful to investors as supplemental measures in evaluating the aggregate performance of the Company. We exclude restructuring and other related charges, transaction-related costs, costs related to early extinguishment of debt and certain other items as such items are not representative of the results of operations of our business less a provision for income taxes derived utilizing applicable statutory tax rates for each item. A reconciliation of our Adjusted earnings Non-GAAP measures from the appropriate measures recognized under GAAP is provided on Table 5.

Adjusted Free Cash Flow
Represents Net Cash Provided by Operating Activities adjusted to reflect the cash inflows and outflows relating to capital expenditures, the investing and financing activities of our vehicle programs, asset sales, if any, and to exclude debt extinguishment costs, transaction-related costs, restructuring and other related charges, charges for unprecedented personal-injury and other legal matters, COVID-19 charges and non-operational charges related to shareholder activist activity. We have revised our definition of Adjusted Free Cash Flow to exclude amounts recorded in excess of $5 million related to class action lawsuits and have not revised prior years' Adjusted Free Cash Flow amounts as there were no other charges similar in nature to these. We believe this change is meaningful to investors as it brings the measurement in line with our other non-GAAP measures. We believe that Adjusted Free Cash Flow is useful to management and investors in measuring the cash generated that is available to be used to repay debt obligations, repurchase stock, pay dividends and invest in future growth through new business development activities or acquisitions. Adjusted Free Cash Flow should not be construed as a substitute in measuring operating results or liquidity, and our presentation of Adjusted Free Cash Flow may not be comparable to similarly-titled measures used by other companies. A reconciliation of Adjusted Free Cash Flow to the appropriate measure recognized under GAAP is provided on Table 4.
