Basis of Preparation—The consolidated financial statements have been presented in U.S. dollars and prepared in accordance with United States generally accepted accounting principles (“GAAP”). Certain monetary amounts, percentages, and other figures included elsewhere in these consolidated financial statements and accompanying notes have been subject to rounding adjustments. As such, figures shown as totals in certain tables may not be the arithmetic aggregation of the figures that precede them, and figures expressed as percentages in the text may not total 100% or, as applicable, when aggregated may not be the arithmetic aggregation of the percentages that precede them.

Reverse Stock Split—On August 30, 2024, following stockholder and Board of Directors’ approval, we announced that we had filed with the Secretary of State of the State of Delaware a Certificate of Amendment to the Company’s Ninth Amended and Restated Certificate of Incorporation (the “Certificate”) to effect a reverse stock split (the “Reverse Stock Split”) of the Company’s Class A common stock and Class B common stock (together the “common stock”), at a ratio of 1-for-20, effective as of 5:00 p.m. Eastern Standard Time on September 4, 2024 (the “Effective Time”). Accordingly, each holder of common stock owned fewer shares of common stock as a result of the Reverse Stock Split. However, the Reverse Stock Split affected all holders of common stock uniformly and did not affect any stockholder’s percentage ownership interest in the Company, except to the extent that the Reverse Stock Split resulted in an adjustment to a stockholders’s ownership of common stock due to the treatment of fractional shares in the Reverse Stock Split. Therefore, voting rights and other rights and preferences of the holders of Common Stock were not affected by the Reverse Stock Split (other than as a result of the treatment of fractional shares). Common stock issued pursuant to the Reverse Stock Split remained fully paid and nonassessable, without any change in the par value per share.

No fractional shares were issued as a result of the Reverse Stock Split. Instead, each stockholder received a cash payment equal to the fraction of which such stockholder was otherwise entitled multiplied by the closing price per share of Class A common stock on the date of the Effective Time as reported by Nasdaq (as adjusted to give effect to the Reverse Stock Split). The common stock began trading on a Reverse Stock Split-adjusted basis on The Nasdaq Global Select Market on September 5, 2024. The trading symbol for the Class A common stock remained “BIRD.”

Use of Estimates—The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates.

Risks and Uncertainties—We continue to monitor and respond to evolving developments about recent macroeconomic events, including elevated inflation, the U.S. Federal Reserve adjusting interest rates, bank failures, supply chain disruptions, fluctuations in currency exchange rates, tariffs, and geopolitical conflicts, which have led to economic uncertainty in the global economy. These macroeconomic conditions have had and are likely to continue to have adverse consequences on consumer spending, including the buying patterns of our customers and prospective customers. The conditions caused by the aforementioned recent macroeconomic events could affect the rate of consumer spending and could adversely affect demand for our products, lengthen our sales cycles, reduce the value of inventory, reduce expected spending from new customers, and affect our suppliers, all of which could adversely affect our business, results of operations, and financial condition.

As of the date of the issuance of the financial statements, we are not aware of any specific event or circumstance related to the aforementioned macroeconomic events that would require us to update our estimates or judgments or adjust the carrying value of our assets or liabilities. Actual results could differ from those estimates and any such differences may be material to the consolidated financial statements.

Segments—We operate as one operating segment. Our Chief Executive Officer is our chief operating decision maker who evaluates performance and makes operating decisions about allocating resources based on consolidated financial data. There was no change in our operating segments as a result of the change in CEO during the first quarter of 2024. Refer to Note 8 for more information on our segments and geographic information.

Foreign Currency Transactions—Our reporting currency is the U.S. dollar. The functional currency for each subsidiary included in these consolidated financial statements that is domiciled outside of the United States is generally the applicable local currency of that country or the U.S. dollar. The translation of foreign currencies into U.S. dollars is performed for assets and liabilities using current foreign currency exchange rates in effect at the balance sheet date and for revenues and expense accounts using average foreign currency exchange rates during the period. Capital accounts are translated at historical foreign currency exchange rates. Translation gains and losses are included in stockholders’ equity as a component of accumulated other comprehensive income or loss. Adjustments that arise from foreign currency exchange rate changes on transactions denominated in a currency other than the functional currency are recognized as other income or expense within the consolidated statements of operations and comprehensive loss.

Cash, Cash Equivalents, and Restricted Cash—We consider all highly liquid investments with an original maturity date of three months or less as cash equivalents. Cash and cash equivalents are comprised primarily of domestic and foreign bank accounts and money market funds. These cash and cash equivalents are valued based on Level 1 inputs, which consist of quoted prices in active markets. We place our cash and cash equivalents with several high credit quality financial institutions which, at times, may be in excess of Federal Deposit Insurance Corporation (“FDIC”) insurance limits. We have not experienced any losses in such accounts and periodically evaluate the credit worthiness of the financial institutions. Our foreign bank accounts are not subject to FDIC insurance.

Restricted cash serves as collateral for a bond with the United States Customs and Border Protection (“CBP”), which allows us to take possession of our inventory before all formalities with the CBP are completed for imported products. Restricted cash is included in prepaid expenses and other current assets on the consolidated balance sheets.

Accounts Receivable—Accounts receivable consist primarily of amounts due from customers, which results from sales to customers including credit card deposits in transit at the balance sheet date, the majority of which are settled within 2 to 3 business days, and third-party accounts receivable, which are settled per the terms of the sale. Third-party accounts receivable was $4.9 million and $4.6 million as of December 31, 2024 and 2023, respectively. Credit card receivables were $1.0 million and $2.3 million as of December 31, 2024 and 2023, respectively.

We periodically review inventory and record reserves as necessary to appropriately value slow-moving, damaged, and excess inventory. To determine if the value of inventory requires a write-down, we estimate the market value of inventory by considering current and anticipated demand, customer preferences and buying trends, and the age of the merchandise. Inventory write-downs are recognized as cost of revenue in the consolidated statements of operations and comprehensive loss. As of December 31, 2024 and 2023, we recorded an inventory reserve to reduce the value of our inventory by $3.6 million and $6.5 million, respectively, within inventory on the consolidated balance sheets. We recognized $7.0 million and $10.5 million of inventory write-downs for the years ended December 31, 2024 and 2023, respectively.

Investments—We account for our investments in equity securities under the measurement alternative described in FASB ASC Topic 321, Investments - Equity Securities, which requires the accounting for equity investments without a readily determinable fair value, which are not accounted for under the equity method of accounting, be measured at their cost, less impairment, if any, and adjusted for observable price changes arising from orderly transactions in the same or similar investment from the same issuer. These investments are carried on the consolidated balance sheets within other assets. Any unrealized gains or losses or impairments will be reported within earnings in our consolidated statements of operations and comprehensive loss. We assess whether an other-than-temporary impairment loss on an investment has

Property and Equipment - Net—Property and equipment - net is stated at cost less accumulated depreciation. Depreciation and amortization expense is computed using the straight-line method over the estimated useful lives of the respective assets, which are generally three to five years. Leasehold improvements are amortized over the shorter of estimated useful lives of the assets or the term of the associated lease. Expenditures for repairs and maintenance are expensed as incurred. Upon disposal, the cost and related accumulated depreciation are removed from the accounts, and the resulting gain or loss is recognized as other income or expense in the consolidated statements of operations and comprehensive loss.

Capitalized Internal-Use Software—Costs of software developed for internal-use is accounted for in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Subtopic 350-40, Internal-Use Software. Capitalization of costs begins when the preliminary project stage is completed, management authorizes and commits to funding the computer software project, it is probable that the project will be completed, and the software will be used to perform the function intended. Such costs are capitalized in the period incurred. Capitalization ceases at the point when the project is substantially complete and ready for its intended use. The capitalized costs are amortized using the straight-line method over the estimated useful lives of the software, which is generally three years. For the years ended December 31, 2024 and 2023, we capitalized $4.2 million and $11.0 million, respectively, in internal-use software within property and equipment in the consolidated balance sheets.

Leases—We determine if an arrangement is or contains a lease at inception by evaluating various factors, including if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration and other facts and circumstances. Lease classification is determined at the lease commencement date. Right-of-use assets represent our right to use an underlying asset for the lease term, and lease liabilities represent our obligation to make payments arising from the lease. Operating lease right-of-use assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. Lease payments consist primarily of the fixed payments under the arrangement, less any lease incentives. Variable lease payments are expensed as incurred and include certain non-lease components, such as maintenance and other services provided by the lessor to the extent the charges are variable. Lease expense for lease payments is recognized on a straight-line basis over the lease term. For any right-of-use assets that are impaired, the lease expense is no longer recognized on a straight-line basis.

We use an estimate of our incremental borrowing rate (“IBR”) based on the information available at the lease commencement date in determining the present value of lease payments, unless the implicit rate is readily determinable. The IBR is the company specific rate of interest that would have to be paid by us to borrow on a collateralized basis over a similar term of the lease in a similar economic environment as of the date of the lease. In determining the appropriate IBR, we consider various factors, including, but not limited to, the lease term, our credit rating, U.S Treasury rates, and the currency in which the arrangement is denominated. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option.

We do not separate non-lease components from lease components for our leases. In addition, we do not recognize right-of-use assets and lease liabilities for short-term leases, which have a lease term of 12 months or less and do not include an option to purchase the underlying asset that we are reasonably certain to exercise. Lease cost for short-term leases is recognized on a straight-line basis over the lease term.

Impairment of Long-Lived Assets—We evaluate the recoverability of property and equipment, operating lease right-of-use assets, and identifiable intangible assets with definite lives (“long-lived assets) whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. When a triggering event occurs, a test for recoverability is performed, comparing projected undiscounted future cash flows to the carrying value of the asset group. If the carrying amount of an asset group exceeds its estimated undiscounted net future cash flows, an impairment charge is recognized for the amount by which the carrying amount of the asset group exceeds its fair value.

Long-lived assets are reviewed for recoverability at the lowest level in which there are identifiable cash flows (asset group), which we determined are at the individual store level. The carrying amount of a store asset group includes stores’ operating lease right-of-use assets and property and equipment, which consists primarily of leasehold improvements. We evaluate corporate assets or other long-lived assets that are not store-specific at the consolidated level.

We determined that triggering events, including a current-period and history of operating cash flow losses, occurred during 2024 and required an impairment review of our long-lived assets. Based on the results of our undiscounted cash flow analysis, we identified certain asset groups in which the projected future undiscounted net cash flows are less than the carrying value of an asset group. For these asset groups, we determined that the fair values exceeded the carrying values and therefore, no impairment charges were recognized for the year ended December 31, 2024. There is uncertainty in the projected undiscounted future cash flows used in our impairment review analysis, which requires the use of estimates and assumptions. If our actual performance does not achieve our projections, or if the assumptions used change in the future, we may be required to recognize impairment charges in future periods, and any such charges could be material.

Restructuring—In the first quarter of 2023, we announced a strategic transformation plan designed to improve our revenue trend, as well as improve capital efficiency and drive profitability in the business. As part of this effort, we have incurred professional fees, severance and other employee-related benefits, and other related charges which are recognized within restructuring expense in the consolidated statements of operations and comprehensive loss.

Business Combinations and Dispositions—In 2023 and 2024, we entered into agreements appointing exclusive distributors in South Korea, Canada, Australasia, Japan, and China. As part of the appointments, we entered into an asset purchase agreement with each distributor for the sale of certain net assets used in connection with the operations of our businesses in the respective territories. Refer to Note 3, Business Combinations and Dispositions, for further details.

Revenue Recognition—Our primary source of revenue is from sales of shoes and apparel products. We sell products directly through our own digital channels (including our websites, our discontinued mobile app, and marketplace platforms), our leased retail stores, and third-party retailers and distributors.

Revenue transactions associated with the sale of our inventory comprise a single performance obligation which consists of the sale of products to customers through our direct to consumer or third-party channels. Payment is due either at the time of purchase or within a timeframe specified in the contract, without significant financing components. We satisfy the performance obligation and record revenues when transfer of control to the customer has occurred, based on the terms of sale. A customer is considered to have control once they are able to direct the use and receive substantially all of

the benefits of the product. Control is transferred to third-party customers upon shipment. Control transfers to retail store customers at the time of sale (receipt) and to digital customers upon shipment. This transfer of control represents a single deliverable and revenue is recognized at a point in time. All revenue is reported net of sales taxes collected from customers on behalf of taxing authorities and variable consideration, including returns and discounts. We account for shipping and handling fees charged to customers as revenue and we account for shipping and handling costs as fulfillment costs. We recognize the revenue and costs associated with shipping and handling at the time the products are shipped to the customer.

In the normal course of business, payment may be collected from the customer prior to recognizing revenue and such, cash receipts are included in deferred revenue in the consolidated balance sheets until control has transferred to the customer. For the years ended December 31, 2024 and 2023, we recognized $3.4 million and $4.1 million, respectively, of revenue that was deferred as of December 31, 2023 and 2022. As of December 31, 2024 and 2023, we had $0.3 million and $0.8 million, respectively, in cash collections of purchases via our digital channel which had not yet shipped. The deferred revenue balance of $3.9 million at December 31, 2024 is expected to be recognized over the next 12 months.

We offer non-expiring gift cards and merchandise credits to our customers. Proceeds from the sale of gift cards are initially deferred and recognized within deferred revenue on the consolidated balance sheets, and are recognized as revenue when the product is received by the customer after the gift card has been tendered for payment. As of December 31, 2024 and 2023, we had $3.6 million and $3.8 million in gift card liabilities on the consolidated balance sheets.

Our sales policy allows customers to return merchandise for any reason within 30 days of receipt for an exchange or refund. We record a reserve for estimated product returns, based upon historical returns, impact of seasonality, current economic and market trends, current business practices, and changes in customer demand and acceptance of our products, in each reporting period as an offsetting decrease of net revenue, with an increase to our sales-refund reserve in accrued expenses. We have also recorded a related inventory returns receivable, less expected costs to recover, in prepaid expenses and other current assets with an offsetting decrease to cost of revenue as of December 31, 2024 and 2023 in the consolidated balance sheets.

Cost of Revenue—Cost of revenue primarily consists of the cost of purchased inventory, inbound and outbound shipping costs, import duties, distribution center and related equipment costs, and inventory write-offs and write-downs. Shipping costs to receive products from our suppliers are included in the cost of inventory and recognized as cost of revenue upon sale of products to our customers.

Selling, General, and Administrative Expense—Selling, general, and administrative expense consists of personnel and related costs including salaries, benefits, bonuses, and stock-based compensation for our corporate and retail employees, third-party professional fees, information technology, payment processing fees, fixed and variable lease costs for corporate offices and retail stores, depreciation and amortization, software costs, legal fees, and other administrative costs associated with operating the business.

Stock-Based Compensation—Stock-based compensation expense related to stock awards, including stock options, restricted stock units (“RSUs”), stock awards with market-based or performance-based vesting conditions, and stock purchase rights granted under the 2021 Employee Stock Purchase Plan (“ESPP Rights”), is recognized based on the estimated fair value of the awards on the date of the grant. The fair value of each stock option award and ESPP Right is valued on the grant date using the Black-Scholes option pricing model. The fair value of each RSU is based on the estimated fair value of our common stock on the date of grant. The fair of stock awards with market-based or performance-based vesting conditions is based on the estimated fair value using equity valuation models, such as the Monte Carlo simulation, using assumptions and judgements made by management and third-party valuation specialists. Stock-based compensation is generally recognized on a straight-line basis over the requisite service period, which is generally the vesting period of the respective award. Forfeitures are accounted for in the period in which they occur.

The Black-Scholes option pricing model requires the input of highly subjective assumptions, including the fair value of the underlying common stock, the expected term of the option, the expected volatility of the price of our common stock, risk-free interest rates and the expected dividend yield of our common stock. The assumptions used to determine the fair value of the option awards represent management’s best estimates. These estimates involve inherent uncertainties and the application of management’s judgment.

Income Taxes—We record deferred tax assets and liabilities based on differences between the book and tax bases of assets and liabilities. The deferred tax assets and liabilities are calculated by applying enacted tax rates and laws to taxable years in which such differences are expected to reverse. We determine whether a valuation allowance is necessary in accordance with the provisions of the FASB ASC 740, Income Taxes. We recognize the benefits from our deferred tax assets only when an analysis of both positive and negative factors indicate that it is more likely than not that the benefits will be realized.

Our estimate of the potential outcome of any uncertain tax position is subject to our assessment of relevant risks, facts, and circumstances existing at that time. Obtaining new information, settlements with tax authorities and the expiration of statutes of limitations may cause adjustments in income tax expense in the period this occurs.

Fair Value Measurements—FASB ASC 820, Fair Value Measurements, defines fair value, establishes a framework for measuring fair value under GAAP, and enhances disclosures about fair value measurements. It clarifies that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, ASC 820 establishes a three-tier value hierarchy, which prioritizes the inputs used in measuring fair value as follows:

This hierarchy requires us to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value. We record cash and cash equivalents, accounts receivable, accounts payable, and accrued expenses at cost. The carrying values of these instruments approximate their fair value due to their short‐term maturities. We hold certain assets that are required to be measured at fair value on both a recurring and non-recurring basis, which are outlined in Note 5, Fair Value Measurements.

Emerging Growth Company—As an “emerging growth company,” the Jumpstart Our Business Startups Act, or the JOBS Act, allows us to delay adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements are made applicable to private companies. For certain pronouncements, we have elected to use the adoption dates applicable to private companies. As a result, our financial statements may not be comparable to the financial statements of issuers who are required to comply with the effective date for new or revised accounting standards that are applicable to public companies.

In August 2020, the FASB issued ASU No. 2020-06, Accounting for Convertible Instruments and Contracts in an Entity's Own Equity, which simplifies the accounting for certain convertible instruments, amends the guidance on derivative scope exceptions for contracts in an entity's own equity, and modifies the guidance on diluted earnings per share calculations as a result of these changes. The guidance is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. The adoption of the guidance in the first quarter of 2024 did not have a material impact on our consolidated financial statements and related disclosures.

In March 2023, the FASB issued ASU No. 2023-01, Leases (Topic 842) - Common Control Arrangements. This ASU addresses issues related to accounting for leases under common control arrangements. The standard will include an amendment to Topic 842 for all entities with leasehold improvements in common control arrangements to amortize leasehold improvements that it owns over the improvements’ useful life to the common control group if certain criteria are met. The amendments in this update are effective for reporting periods beginning after December 15, 2023, with early

In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which amended disclosure requirements for segment reporting. The amendments in this ASU improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses, amendments to enhance interim disclosure requirements and introduce additional details about the chief operating decision maker. These changes address certain investor concerns that disclosures over reportable segment expenses were limited. The amendments in this update are effective for annual reporting periods beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. We adopted this during the year ended December 31, 2024. For further details refer to Note 8, Segments and Geographic Information.

In October 2023, the FASB issued ASU No. 2023-06, Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative, which amends the disclosure or presentation requirements of a variety of topics in the ASC in order to conform with certain SEC amendments in Release No. 33-10532, Disclosure Update and Simplification. The effective date for each amendment will be the date on which the SEC removes that related disclosure from its rules. However, if by June 30, 2027, the SEC has not removed the related disclosure from its regulations, the amendments will be removed from the Codification and not become effective. Early adoption is prohibited. We are evaluating the potential impact of this guidance on our consolidated financial statements and related disclosures.

In December 2023, the FASB issued ASU No. 2023-09, Income Tax (Topic 740): Improvements to Income Tax Disclosures, which amended disclosure requirements for income taxes. The primary changes from this update relate to improvements over income tax disclosures related to the rate reconciliation, income taxes paid and other disclosures. These changes help investors better 1) understand on an entity’s’ exposure to potential changes in jurisdictional tax legislation and the ensuing risks and opportunities, (2) assess income tax information that affects cash flow forecasts and capital allocation decisions, and (3) identify potential opportunities to increase future cash flows. The amendments in this update are effective for annual reporting periods beginning after December 15, 2025, with early adoption permitted. We are evaluating the potential impact of this guidance on our consolidated financial statements and related disclosures.

In November 2024, the FASB issued ASU No. 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40). This ASU improves financial reporting by requiring that public business entities disclose additional information about specific expense categories in the notes to financial statements at interim and annual reporting periods. This ASU will be effective for annual periods beginning after December 15, 2026, for interim reporting periods beginning after December 15, 2027, with early adoption is permitted. We are evaluating the potential impact of this guidance on our consolidated financial statements and related disclosures.
