Second Quarter and Full Year 2021 Guidance

Based on information as of today, ACV is providing the following guidance:

Second quarter of 2021:

oTotal revenue of $72 to $75 million, an increase of 60% to 67% year over year

oAdjusted EBITDA loss of $20 to $22 million

Full year 2021:

oTotal revenue of $307 to $313 million, an increase of 47% to 50% year over year

oAdjusted EBITDA loss of $79 to $82 million

Our financial guidance includes the following assumptions:

The current favorable market dynamics driving strong demand and unit prices are expected to continue in the near-term with a return to more normalized levels later in fiscal 2021.

Total operating expense growth of approximately 63% at the midpoint of guidance.

Reconciliation of Adjusted EBITDA to the most directly comparable GAAP measure is not available without unreasonable efforts on a forward-looking basis due to the high variability, complexity and low visibility with respect to the charges excluded from this non-GAAP measure; in particular, the effects of stock-based compensation expense specific to equity compensation awards that are directly impacted by unpredictable fluctuations in our stock price. We expect the variability of the above charges to have a significant, and potentially unpredictable, impact on our future GAAP financial results.

Partial Early Lock-Up Release

ACV confirmed today that conditions were satisfied for a partial early lock-up release that will occur at the open of trading on May 18, 2021 with respect to its shares of Class A common stock, par value $0.01 per share, pursuant to the terms of certain lock-up agreements entered into by ACV’s directors, officers, and other stockholders with the underwriters of ACV’s initial public offering.

Pursuant to the terms of the lock-up agreements, the lock-up restrictions will end with respect to 25% of the securities owned by the applicable holder only if certain share price and other conditions are met. The conditions for early release were satisfied on May 13, 2021. The lock-up restrictions will continue to apply with respect to all remaining securities subject to the lock-up agreements.

Information About Non-GAAP Financial Measure and Key Operating and Financial Metrics

We supplement our financial results with a non-GAAP financial measure, Adjusted EBITDA, and key operating and financial metrics, Marketplace Units and Marketplace GMV.

Non-GAAP Financial Measure

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.

3

We calculate Adjusted EBITDA as net (loss) income, adjusted to exclude: (1) depreciation and amortization; (2) stock-based compensation expense; (3) interest (income) expense; (4) provision for income taxes; and (5) other (income) expense, net.

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 of Adjusted EBITDA 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 expenses, including interest expense, and (5) it does not reflect tax payments that may represent a reduction in cash available to us. In addition, our use of Adjusted EBITDA may not be 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. Because of these limitations, when evaluating our performance, you should consider Adjusted EBITDA alongside other financial measures, including our net loss and other results stated in accordance with GAAP.

Operating 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. Management intends to report Marketplace Participants, which is defined as dealers or commercial partners with a unique customer ID that have transacted at least once in the last 12 months as either a buyer or seller on our digital marketplace, on an annual basis.

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. Because our definition of Marketplace Units does not include vehicles inspected but not sold on our digital marketplace, GMV does not represent revenue earned by us.

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 digital 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 exclude 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 Marketplace Participants and increased our share of wholesale transactions from existing customers.
