Table Of Contents OLO INC. Notes to the Condensed Consolidated Financial Statements (Unaudited) outstanding redeemable convertible preferred stock, inclusive of the shares issued pursuant to these warrant exercises, converted into 100,196,780 shares of Class B common stock. The redeemable convertible preferred stock warrant liability was reclassified to additional paid-in capital in connection with the IPO. For the three months ended March 31, 2021, we recorded a fair value adjustment of approximately $18.9 million using the intrinsic value of each warrant on the date of the conversion immediately prior to the IPO, as the warrants were significantly in-the-money and the Black-Scholes inputs have a de minimis impact on their value. 14. Income Taxes We had an effective tax rate of 10.39% and (0.14)% for the three months ended March 31, 2022 and 2021, respectively. The effective tax rate for the three months ended March 31, 2022 is driven primarily by the release of a portion of our valuation allowance for deferred tax assets following the recording of a deferred income tax liability as part of our accounting for the acquisition of Omnivore and adjustments to the full valuation allowance on our deferred tax assets, partially offset by state taxes. We maintain a full valuation allowance on our net federal and state deferred tax assets as we have concluded that it is more likely than not that the deferred tax assets will not be realized. We evaluated the available evidence supporting the realization of our deferred tax assets, including the amount and timing of future taxable income, and have determined that it is more likely than not that our net deferred tax assets will not be realized. Due to uncertainties surrounding the realization of the deferred tax assets, we maintain a full valuation allowance against substantially all of our net deferred tax assets. When we determine that we will be able to realize some portion or all of our deferred tax assets, an adjustment to our valuation allowance on our deferred tax assets would have the effect of increasing net income in the period such determination is made. We applied ASC 740, Income Taxes , and determined that we do not have any uncertain positions that would result in a tax reserve for each of the three months ended March 31, 2022 and 2021. Our policy is to recognize interest and penalties related to uncertain tax positions in income tax expense. We are subject to U.S. federal tax authority and state tax authority examinations. 15. Commitments and Contingencies Contingencies Liabilities for loss contingencies arising from claims, assessments, litigation, fines, and penalties and other sources are recorded when it is probable that a liability has been incurred and the amount can be reasonably estimated. If we determine that a loss is reasonably possible, and the loss or range of loss can be estimated, we will disclose the possible loss in the notes to our financial statements. Accounting for contingencies requires us to use judgment related to both the likelihood of a loss and the estimate of the amount or range of loss. Legal costs incurred in connection with loss contingencies are expensed as incurred. We have also received, and may in the future continue to receive, claims from third parties asserting, among other things, infringement of their intellectual property rights. Future litigation may be necessary to defend ourselves or our customers by determining the scope, enforceability, and validity of third-party proprietary rights or to establish our proprietary rights. Defending such proceedings is costly and can impose a significant burden on management and employees. The results of any current or future litigation cannot be predicted with certainty, and regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources, and other factors. 21
