ACV Announces Third Quarter 2023 Results
Delivers Strong Revenue with Adjusted EBITDA Ahead of Guidance
Raises 2023 Guidance

BUFFALO, November 6, 2023 — ACV (Nasdaq: ACVA), a leading digital automotive marketplace and data services partner for dealers and commercial clients, today reported results for its third quarter ended September 30, 2023.

“We are very pleased with our strong third quarter results, with revenue at the high-end of our guidance range, along with year-over-year margin expansion, resulting in Adjusted EBITDA exceeding our guidance range,” said George Chamoun, CEO of ACV.

“Dealer wholesale volumes remain constrained relative to historical levels, however new vehicle production and retail sales are improving, which are key factors supporting a wholesale market recovery. Our strong market position and competitive moat resulted in continued market share gains and accelerated revenue growth in the quarter. We launched new technology solutions that expand our addressable market and drive operating efficiency, which we achieved while increasing margins,” continued Chamoun.

“We have again raised full-year guidance reflecting our strong third quarter performance. We believe ACV remains well positioned to deliver sustainable growth as end-markets further recover, while also continuing to scale our business model,” concluded Chamoun.

Information About Non-GAAP Financial Measures

ACV provides supplemental non-GAAP financial measures to its financial results. We use these non-GAAP financial measures, and we believe that they assist our investors to make period-to-period comparisons of our operating performance because they provide a view of our operating results without items that are not, in our view, indicative of our operating results. These non-GAAP financial measures should not be construed as an alternative to GAAP results as the items excluded from the non-GAAP financial measures often have a material impact on our operating results, certain of those items are recurring, and others often recur. Management uses, and investors should consider, our non-GAAP financial measures only in conjunction with our GAAP results.

Non-GAAP Financial Measures

Adjusted EBITDA is a financial measure that is not presented in accordance with GAAP. We believe that Adjusted EBITDA, when taken together with our financial results presented in accordance with GAAP, provides meaningful supplemental information regarding our operating performance and facilitates internal comparisons of our historical operating performance on a more consistent basis by excluding certain items that may not be indicative of our business, results of operations or outlook. In particular, we believe that the use of Adjusted EBITDA is helpful to our investors as it is a measure used by management in assessing the health of our business, determining incentive compensation and evaluating our operating performance, as well as for internal planning and forecasting purposes.

We define Adjusted EBITDA as net loss, adjusted to exclude: depreciation and amortization; stock-based compensation expense; interest (income) expense; provision for income taxes; other (income) expense, net; and other one-time non-recurring items of a material nature, when applicable, such as acquisition-related and restructuring expenses.

Adjusted EBITDA is presented for supplemental informational purposes only, has limitations as an analytical tool and should not be considered in isolation or as a substitute for financial information presented in accordance with GAAP. Some of the limitations include that (1) it does not properly reflect capital commitments to be paid in the future; (2) although depreciation and amortization are non-cash charges, the underlying assets may need to be replaced and Adjusted EBITDA does not reflect these capital expenditures; (3) it does not consider the impact of stock-based compensation expense, (4) it does not reflect other non-operating income or expenses, including interest income and expense, (5) it does not consider the impact of any contingent consideration liability valuation adjustments, (6) it does not reflect tax payments that may represent a reduction in cash available to us, and (7) it does not reflect other one-time, non-recurring items of a material nature, when applicable, such as acquisition-related and restructuring expenses. In addition, our use of Adjusted EBITDA may not be

3

comparable to similarly titled measures of other companies because they may not calculate Adjusted EBITDA in the same manner, limiting its usefulness as a comparative measure.

Non-GAAP net income (loss), a financial measure that is not presented in accordance with GAAP, provides investors with additional useful information to measure operating performance and current and future liquidity when taken together with our financial results presented in accordance with GAAP. By providing this information, we believe management and the users of the financial statements are better able to understand the financial results of what we consider to be our organic, continuing operations.

We define non-GAAP net income (loss) as net income (loss), adjusted to exclude: stock-based compensation expense, amortization of acquired intangible assets, and other one-time, non-recurring items of a material nature, when applicable, such as acquisition-related and restructuring expenses.

In the calculation of non-GAAP net income (loss), we exclude stock-based compensation expense because of varying available valuation methodologies, subjective assumptions and the variety of equity instruments that can impact our non-cash expense. We believe that providing non-GAAP financial measures that exclude stock-based compensation expense allows for more meaningful comparisons between our operating results from period to period.

We exclude amortization of acquired intangible assets from the calculation of non-GAAP net income (loss). We believe that excluding the impact of amortization of acquired intangible assets allows for more meaningful comparisons between operating results from period to period as the underlying intangible assets are valued at the time of acquisition and are amortized over several years after the acquisition.

We exclude contingent consideration liability valuation adjustments associated with the purchase consideration of transactions accounted for as business combinations. We also exclude certain other one-time, non-recurring items of a material nature, when applicable, such as acquisition-related and restructuring expenses, because we do not consider such amounts to be part of our ongoing operations nor are they comparable to prior period nor predictive of future results.

Non-GAAP net income (loss) is presented for supplemental informational purposes only, has limitations as an analytical tool and should not be considered in isolation or as a substitute for financial information presented in accordance with GAAP. Some of these limitations include that: (1) it does not consider the impact of stock-based compensation expense; (2) although amortization is a non-cash charge, the underlying assets may need to be replaced and non-GAAP net income (loss) does not reflect these capital expenditures; (3) it does not consider the impact of any contingent consideration liability valuation adjustments; and (4) it does not consider the impact of other one-time charges, such as acquisition-related and restructuring expenses, which could be material to the results of our operations. In addition, our use of non-GAAP net income (loss) may not be comparable to similarly titled measures of other companies because they may not calculate non-GAAP net income (loss) in the same manner, limiting its usefulness as a comparative measure.

Information About Operating and Financial Metrics

We regularly monitor the following operating and financial metrics in order to measure our current performance and estimate our future performance. Our key operating and financial metrics may be calculated in a manner different than similar business metrics used by other companies.

Operating and Financial Metrics

Marketplace GMV - Marketplace GMV is primarily driven by the volume and dollar value of Marketplace Units transacted on our digital marketplace. We believe that Marketplace GMV acts as an indicator of the success of our marketplace, signaling satisfaction of dealers and buyers on our marketplace, and the health, scale, and growth of our business. We define Marketplace GMV as the total dollar value of vehicles transacted through our digital marketplace within the applicable period, excluding any auction and ancillary fees.

Marketplace Units - Marketplace Units is a key indicator of our potential for growth in Marketplace GMV and revenue. It demonstrates the overall engagement of our customers on the ACV platform, the vibrancy of our digital marketplace and our market share of wholesale transactions in the United States. We define Marketplace Units as the number of vehicles transacted on our marketplace within the applicable period. Marketplace Units transacted includes any vehicle that successfully reaches sold status, even if the auction is subsequently unwound, meaning the buyer or seller does not complete the transaction. These instances have been immaterial to date. Marketplace Units excludes vehicles that were inspected by ACV, but not sold on our digital marketplace. Marketplace Units have increased over time as we have expanded our territory coverage, added new dealer partners and increased our share of wholesale transactions from existing customers.
