Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Revenue Recognition The Company recognizes revenue under ASC 606, Revenue from Contracts with Customers . The core principle of the revenue standard is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The Company only applies the five-step model to contracts when it is probable that the Company will collect the consideration it is entitled to in exchange for the goods and services transferred to the customer. The following five steps are applied to achieve that core principle: Step 1: Identify the contract with the customer Step 2: Identify the performance obligations in the contract Step 3: Determine the transaction price Step 4: Allocate the transaction price to the performance obligations in the contract Step 5: Recognize revenue when the company satisfies a performance obligation The Company does not have any significant contracts with customers requiring performance beyond delivery. Blade operates in three key product lines across two segments (see Note 7 for further information on reportable segments): Passenger segment • Short Distance – Consisting primarily of helicopter and amphibious seaplane flights in the United States, Canada and Europe between 10 and 100 miles in distance. Flights are available for purchase both by-the-seat and on a full aircraft charter basis. Short Distance products are typically purchased using the Blade App and paid for principally via credit card transactions, wire, check, customer credit, and gift cards, with payments principally collected by the Company in advance of the performance of related services. Part of the revenue in Europe is driven by hotels and travel agencies who receive payment terms. The revenue is recognized as the service is completed. • Jet and Other – Consists principally of revenues from non-medical jet charter and by-the-seat jet flights between New York and South Florida, revenue from brand partners for exposure to Blade fliers and certain ground transportation services. Jet products are typically purchased through our Flier Relations associates and our app and are paid for principally via checks, wires and credit card. Jet payments are typically collected at the time of booking before the performance of the related service. The revenue is recognized as the service is completed. Medical segment • MediMobility Organ Transport – Consisting primarily of transportation of human organs for transplant and/or the medical teams supporting these services. Blade also offers additional services including donor logistics coordination and support evaluating potential donor organs. MediMobility Organ Transport products are typically purchased through our medical logistics coordinators and are paid for principally via checks and wires. Payments are generally collected after the performance of the related service in accordance with the client's payment terms. The revenue is recognized as the service is completed. The Company initially records flight sales in deferred revenue, deferring revenue recognition until the travel occurs. Deferred revenue from advance payments, customer credit and gift card purchases is recognized as revenue when a flight is flown. Deferred revenue from the Company’s passes is recognized ratably over the term of the pass. For travel that has more than one flight segment, the Company deems each segment as a separate performance obligation and recognizes revenue for each segment as travel occurs. Fees charged in association with add-on services or changes or extensions to non-refundable seats sold are considered part of the Company's passenger performance obligation. As such, those fees are deferred at the time of collection and recognized at the time the travel is provided. Contract Liabilities Contract liability is defined as entity’s obligation to transfer goods or services to a customer for which the entity has received consideration (or the amount is due) from the customer. As of December 31, 2023 and 2022, the Company's contract liability balance is $6,845 and $6,709 respectively, and is recorded as deferred revenue on the consolidated balance sheets. This balance consists of payments from customers received in advance of the actual flight, prepaid monthly and annual flight passes, customer credits for flight reservations that were cancelled for good reason by the customer, and prepaid gift card obligations. The customer has one year to use the credit as payment for a future flight with the Company. Gift cards represent prepayment of flights. The table below presents a roll forward of the contract liability balance: For the Years Ended December 31, December 31, Balance, beginning of period $ 6,709 $ 5,976 Additions 69,792 72,742 Revenue recognized (69,656) (72,009) Balance, end of period $ 6,845 $ 6,709 For the year ended December 31, 2023, the Company recognized $5,836 of revenue that was included in the contract liability balance as of January 1, 2023. For the year ended December 31, 2022, the Company recognized $4,406 of revenue that was included in the contract liability balance as of January 1, 2022. Certain governmental taxes are imposed on the Company's flight sales through a tax included in flight prices. The Company collects these taxes and remits them to the appropriate government agency. These taxes are excluded from revenue. The Company’s quarterly financial data is subject to seasonal fluctuations. Historically, its second and third quarter (ended on June 30 and September 30, respectively) financial results have reflected higher Passenger travel demand and were better than the first and fourth quarter financial results. Disaggregated Revenue Disaggregated revenue by product line and segment was as follows: For the Years Ended December 31, December 31, Passenger Segment Short Distance $ 70,700 $ 44,986 Jet and Other 27,876 29,355 Total $ 98,576 $ 74,341 Medical Segment MediMobility Organ Transport $ 126,604 $ 71,779 Total $ 126,604 $ 71,779 Total Revenue $ 225,180 $ 146,120 Cost of Revenue Cost of revenue consists of flight costs paid to operators of aircraft and cars, landing fees, ROU asset amortization and internal costs incurred in generating organ ground transportation revenue using the Company's owned cars. Software Development Costs for Internal Use Costs incurred for the development of the Company’s internal use software are expensed as incurred. Software development costs consist primarily of staff costs including stock-based compensation. Selling and Marketing Selling and marketing expenses consist primarily of advertising costs, staff costs including stock-based compensation, marketing expenses, sales commissions and promotion costs. Advertising costs, which are included in “Selling and marketing expenses”, are expensed as incurred. Advertising costs were $4,064 and $4,540 for the years ended December 31, 2023 and 2022, respectively. General and Administrative General and administrative expenses principally include staff costs including stock-based compensation, depreciation and amortization, impairment of intangible assets, directors and officers insurance costs, professional fees, credit card processing fees and establishment costs. Stock-Based Compensation The Company accounts for stock-based compensation in accordance with ASC 718, Compensation - Stock Compensation (“ASC 718”). ASC 718 establishes accounting for stock-based awards exchanged for employee and consultant services. Under the provisions of ASC 718, stock-based compensation cost is measured at the grant date, based on the fair value of the award, and is recognized as expense over the employee’s requisite service period (generally the vesting period of the equity grant). The fair value of the Company’s stock options (the most recent stock options grants were in the year 2021) were estimated using the Black Scholes option-pricing model with the following assumptions: fair value of the Company’s common stock, expected volatility, dividend rate, risk free interest rate, and the expected life. The Company utilized a third party to determine the fair value of the Company’s common stock. The Company calculated the expected volatility using the historical volatility for a pool of peer companies over the most recent period equal to the expected term and evaluated the extent to which available information indicate that future volatility may differ from historical volatility. The expected dividend rate was zero as the Company did not expect to pay or declare any cash dividends on its common stock. The risk-free rates for the expected terms of the stock options were based on the U.S. Treasury yield curve in effect at the time of the grant. The Company had not experienced significant exercise activity on stock options. Due to the lack of historical information, the Company determined the expected term of its stock option awards issued using the simplified method. The simplified method assumed each vesting tranche of the award has a term equal to the midpoint between when the award vests and when the award expires. The Company recognized forfeitures at the time the forfeiture occurs. Restricted stock units (“RSUs”) are granted at the discretion of the Company’s Board of Directors. These RSUs are restricted as to the transfer of ownership and generally vest over the requisite service period. The RSUs have various vesting dates, ranging from vesting on the grant date to as late as four years from the date of grant. The Company's current default tax withholding method for the vesting of RSUs is the sell-to-cover method, under which shares with a market value equivalent to the estimated tax withholding obligation are withheld from the holder of the RSUs upon vesting and sold on behalf of such holder to cover their applicable tax withholding liability, and the cash proceeds from such sales are then remitted by the Company to the applicable tax authorities. This approach is used for the vesting of RSUs held by the majority of the Company’s employees, including all of the Company’s Section 16 “officers” as defined by Section 16 of the Securities and Exchange Act of 1934, as amended. Income Taxes The Company accounts for income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the consolidated financial statements or in the Company’s tax returns. Deferred tax assets and liabilities are determined on the basis of the differences between U.S. GAAP treatment and tax treatment of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. Changes in deferred tax assets and liabilities are recorded in the provision for income taxes. The Company assesses the likelihood that its deferred tax assets will be recovered from future taxable income and, to the extent it believes, based upon the weight of available evidence, that it is more likely than not that all or a portion of the deferred tax assets will not be realized, a valuation allowance is established through a charge to income tax expense. Potential for recovery of deferred tax assets is evaluated by considering taxable income in carryback years, existing taxable temporary differences, prudent and feasible tax planning strategies and estimated future taxable profits. Each period, the Company analyzes whether it is more-likely-than-not that tax positions will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the positions. In evaluating whether a tax position has met the more-likely-than-not recognition threshold, the Company presumes that the position will be examined by the appropriate taxing authority that has full knowledge of all relevant information and considers that all years remain subject to examination in the US due to historical operational losses. When differences exist between tax positions taken in a tax return and amounts meeting the more-likely-than-not threshold, the company will record an uncertain tax position, resulting in one or more of the following: an increase in a liability for income taxes payable, a reduction of an income tax refund receivable, a reduction in a deferred tax asset, or an increase in a deferred tax liability. The Company records penalties and interest relating to uncertain tax positions as part of income tax expense. As of December 31, 2023, the Company has no uncertain tax positions. See Note 8 for additional information. Cash and Cash Equivalents and Restricted Cash The Company considers all highly liquid investments with a maturity of three months or less on their acquisition date as cash and cash equivalents. Restricted cash consists principally of Company funds on deposit with a financial institution, which supports a letter of credit by the financial institution in favor of the Company’s obligations to the United States Department of Transportation as well as deposits posted for collateral with certain of the Company’s vendors. Short-Term Investments Held-to-Maturity Securities The Company's investments in held-to-maturity securities consist of investment grade U.S. Treasury obligations with maturity dates of less than 365 days. The Company has the ability and intention to hold these securities until maturity. Accordingly, these securities are recorded in the Company's consolidated balance sheet at amortized cost and interest is recorded within interest income on the Company's consolidated statement of operations. The held-to-maturity securities balance and market value at December 31, 2023 and 2022 were $138,264 and $138,285, and $130,382 and $130,352, respectively. Other Short-Term Investments Other short-term investments consist of highly-liquid investments available for sale. Other short-term investments consisted of an available-for-sale, traded, debt securities fund, which is recorded at fair value with unrealized gains and losses reported, net of tax, in “Accumulated other comprehensive income (loss)”, unless unrealized losses are determined to be unrecoverable. Realized gains and losses on the sale of securities are determined by specific identification. The Company considers all available-for-sale securities as available to support current operational liquidity needs and, therefore, classifies all securities as current assets within short-term investments on the Company’s consolidated balance sheets. These other short-term investments are excluded from disclosure under “fair value of financial instruments” due to the net asset value practical expedient. The other short-term investments balance at December 31, 2023 and 2022 was $— and $20,358, respectively. The cost of other short-term investments at December 31, 2023 and 2022 was $— and $20,460, respectively. Accounts Receivable and Allowances for Expected Credit Losses Accounts receivable consists principally of amounts due from customers in the Company’s Medical segment, which are large hospitals that receive terms for payment. Additionally, a smaller balance is due from the Company’s European institutional clients (hotels and travel agencies), who do not pay prior to the flights. The allowance for expected credit losses on receivables is used to present accounts receivable, net at an amount that represents the Company’s estimate of the related transaction price recognized as revenue. The allowance represents an estimate of expected credit losses over the lifetime of the receivables, even if the loss is considered remote, and reflects expected recoveries of amounts previously written-off. We have determined our allowance for expected credit losses based on a specific evaluation of individual receivables and an analysis of past default experience for remaining receivables. We have historically not experienced significant losses on our receivables. We generally do not require customers to provide collateral for purchases. During the year ended December 31, 2023, the Company recorded an allowance for credit losses of $98 for potential uncollectible accounts. Prepaid Expenses and Other Current Assets Prepaid expenses includes prepaid insurance, the costs of which are amortized on a straight-line basis over the related coverage periods, prepaid marketing supplies and prepayments to aircraft operators, which are expensed based upon usage of flight time. Property and Equipment, Net Property and equipment are carried at cost, net of accumulated depreciation. Depreciation is computed utilizing the straight-line method over the estimated useful life of the asset. Leasehold improvements depreciation is computed over the shorter of the lease term or estimated useful life of the asset. Additions and improvements are capitalized, while repairs and maintenance are expensed as incurred. Useful Life (in years) As of December 31, 2023 2022 Furniture and fixtures 5 $ 886 $ 407 Technology equipment 3 402 330 Leasehold improvements Shorter of useful life or life of lease 3,016 2,799 Vehicles 5 1,750 735 Total property and equipment, gross 6,054 4,271 Less: Accumulated depreciation and amortization (3,155) (2,234) Total property and equipment, net $ 2,899 $ 2,037 For the years ended December 31, 2023 and 2022, the Company recorded depreciation and amortization expense for property and equipment of $1,075 and $830, respectively. Acquisitions The Company accounts for acquisitions of entities or asset groups that qualify as businesses in accordance with ASC 805, Business Combinations (“ASC 805”). The purchase price of the acquisition is allocated to the tangible and intangible assets acquired and liabilities assumed based on their estimated fair values at the acquisition date. The excess of the purchase price over those fair values is recorded as goodwill. During the measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded in the consolidated statements of operations. See Note 3 for additional information. Intangibles Assets, Net The Company has finite-lived and indefinite-lived intangible assets, including goodwill. Finite-lived intangible assets are amortized over their estimated useful lives. Goodwill and indefinite-lived intangible assets are not amortized but are reviewed for impairment on an annual basis, or more frequently if events or circumstances indicate that the asset may be impaired. Research and development costs are expensed as incurred. Following initial recognition of the finite-lived intangible asset, the asset is carried at cost less any accumulated amortization. Amortization of the asset begins when the asset is available for use. Amortization is recorded in “General and administrative expenses” on the Company’s consolidated statement of operations. See Note 4 for additional information. Impairment of Long-Lived Assets The Company assess long-lived assets for impairment in accordance with the provisions of ASC 360, Property, Plant and Equipment (“ASC 360”). Long-lived assets, except for goodwill and indefinite-lived intangible assets, consist of property and equipment and finite-lived acquired intangible assets, such as exclusive rights to air transportation services, customer lists and trademarks. Long-lived assets, except for goodwill and indefinite intangible assets, are tested for recoverability whenever events or changes in business circumstances indicate that the carrying amount of the asset may not be fully recoverable. If such events or changes in circumstances arise, the Company compares the carrying amount of the long-lived assets to the estimated future undiscounted cash flows expected to be generated by the long-lived assets. If the estimated aggregate undiscounted cash flows are less than the carrying amount of the long-lived assets, an impairment charge, calculated as the amount by which the carrying amount of the assets exceeds the fair value of the assets, is recorded. The fair value of the long-lived assets is determined through various valuation techniques, including estimated discounted cash flows expected to be generated from the long-lived asset and pricing information on comparable market transactions, unless another method provides a more reliable estimate. If an impairment loss is recognized, the adjusted carrying amount of a long-lived asset is recognized as a new cost basis of the impaired asset. Impairment loss is not reversed even if fair value exceeds carrying amount in subsequent periods. See Note 4 for additional information. Goodwill In testing goodwill for impairment, the Company has the option to begin with a qualitative assessment, commonly referred to as “Step 0,” to determine whether it is more likely than not that the fair value of a reporting unit containing goodwill is less than its carrying value. This qualitative assessment may include, but is not limited to, reviewing factors such as macroeconomic conditions, industry and market considerations, cost factors, entity-specific financial performance and other events, such as changes in the Company’s management, strategy and primary customer base. If the Company determines that it is more likely than not that the fair value of a reporting unit is less than its carrying value, the Company performs a quantitative goodwill impairment analysis by comparing the carrying amount to the fair value of the reporting unit. If the carrying amount exceeds the fair value, goodwill will be written down to the fair value and recorded as impairment expense in the consolidated statements of operations. The Company performs its impairment testing annually at December 31 and when circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. We performed an annual test for goodwill impairment in the fourth quarter ended December 31, 2023 and determined that goodwill was not impaired. Leases We determine if an arrangement is a lease at inception. Leases are recorded on the balance sheet as “right-of-use” (“ROU”) assets and lease liabilities. Leases are classified as either operating or finance leases and lease expense is recognized within “General and administrative expenses” (airport and heliport terminals and offices) and “Cost of revenues” (aircraft leases embedded within certain capacity purchase agreements). As a lessee, for operating leases, total lease expense is recognized using a straight-line method. Finance leases are treated as the purchase of an asset on a financing basis. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term. When available, the Company uses the rate implicit in the lease in determining the present value of the future minimum lease payments. However, the Company's leases generally do not provide a readily determinable implicit rate. Therefore, the Company estimates the incremental borrowing rate to discount lease payments based on information available at the inception of the lease. The incremental borrowing rate represents an estimate of the interest rate we would incur at lease commencement to borrow an amount equal to the lease payments on a collateralized basis over the term of the lease. Our lease terms include options to extend the lease when it is reasonably certain that we will exercise that option. Leases with a term of 12 months or less are not recorded on our consolidated balance sheets. Our lease agreements do not contain any residual value guarantees. Under certain of our capacity purchase agreements with third-party aircraft operators, we do not own the underlying aircraft. However, since we control the specific aircraft used, the aircraft is deemed to be leased for accounting purposes. For these capacity purchase agreements, we account for the lease and non-lease components separately. The lease component consists of the aircraft and the non-lease components consist of flight operations. We allocated the consideration in the capacity purchase agreements to the lease and non-lease components based on the Company’s best estimate of standalone value. See Note 5 for additional information. Warrant Liability The Company accounts for warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance in ASC 480, Distinguishing Liabilities from Equity (“ASC 480”) and ASC 815, Derivatives and Hedgin g (“ASC 815”). The assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the warrants meet all of the requirements for equity classification under ASC 815, including whether the warrants are indexed to the Company’s own common shares and whether the warrant holders could potentially require “net cash settlement” in a circumstance outside of the Company’s control, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance and as of each subsequent, quarterly, period-end date while the warrants are outstanding. For issued or modified warrants that meet all of the criteria for equity classification, the warrants are required to be recorded as a component of additional paid-in capital at the time of issuance. For issued or modified warrants that do not meet all the criteria for equity classification, the warrants are required to be recorded at their initial fair value on the date of issuance and each balance sheet date thereafter. The Company accounts for the warrants issued in connection with its Initial Public Offering in accordance with the guidance contained in ASC 815-40-15-7D, under which the warrants do not meet the criteria for equity treatment and must be recorded as liabilities. Accordingly, the Company classifies the warrants as liabilities at their fair value and adjusts the warrants to fair value at each reporting period. This liability is subject to re-measurement at each balance sheet date until exercised, and any change in fair value is recognized in the Company’s consolidated statement of operations. See Notes 12 and 13 for additional information. Concentrations Financial instruments which potentially subject the Company to concentrations of credit risk consists principally of cash amounts on deposit with financial institutions. At times, the Company’s cash in banks is in excess of the Federal Deposit Insurance corporation (“FDIC”) insurance limit. The Company has not experienced any loss as a result of these deposits. Major Customers F or the years ended December 31, 2023 and 2022, there was no single customer that generated 10% or more of the Company’s revenue. Most of the Company’s customers remit payment in advance of the date of the flight. Accounts receivable consists principally of amounts due from the Company’s MediMobility Organ Transport Customers that receive terms for payment, along with receivables from credit card processors. No customer accounted for 10% or more of the Company’s outstanding accounts receivable as of December 31, 2023. One customer accounted for 13% of the Company’s outstanding accounts receivable as of December 31, 2022. Major Vendors One vendor accounted for 12% o f the Company’s purchases from operating vendors for the year ended December 31, 2023 and 2022. Two ve ndors accounted for 17% and 10%, respectively, of the Company’s outstanding accounts payable as of December 31, 2023. One vendor accounted for 20% of the Company’s outstanding payable as of December 31, 2022. Foreign Currency Translation All of our foreign subsidiaries use their local currency as their functional currency. Assets and liabilities are translated from the local functional currency into U.S. Dollars at the exchange rate on the balance sheet date and revenue and expenses are translated at the average exchange rate for the period. Translation adjustments are recorded in accumulated other comprehensive income. Foreign currency gains and losses arising from transactions not in the subsidiaries local currency are recorded in results of operations. Recently Issued Accounting Standards - Adopted On January 1, 2023, we adopted ASU 2021-08, Accounting for Contract Assets and Contract Liabilities From Contracts With Customers , or ASU 2021-08, that requires acquiring companies to apply ASC 606 to recognize and measure contract assets and contract liabilities from contracts with customers acquired in a business combination consistent with those recorded by the acquiring company. The Company does not have significant contracts with customers requiring performance beyond delivery. To the extent we acquire additional companies in our existing lines of business, the adoption of this standard will not have a material impact on our results of operations or financial position. In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments. The ASU changes accounting for credit losses on loans receivable and debt securities from an incurred loss methodology to an expected credit loss methodology. Among other things, ASU 2016-13 requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Accordingly, ASU 2016-13 requires the use of forward-looking information to form credit loss estimates. In addition, ASU 2016-13 amends the accounting for credit losses on debt securities and purchased financial assets with credit deterioration. The Company adopted ASU 2016-13 as of January 1, 2023. The company’s financial assets that are subject to the new standard are predominantly accounts receivable and short-term investments classified as held-to-maturities (e.g., U.S. Treasury obligations). The Company’s receivables consist principally of MediMobility Organ Transport customers, which are large hospitals that receive terms of 45 days or less. U.S. Treasury obligations are rated as investment grade with maturities of less than 365 days. Given our historical experience, the short duration lifetime of these financial assets and the short time horizon over which to consider expectations of future economic conditions, the company assessed that non-collection of the cost basis of these financial assets is remote. The adoption of ASU 2016-13 did not materially impact the Company’s consolidated financial statements. Recently Issued Accounting Pronouncements - Not Adopted In August 2020, the FASB issued ASU No. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging— Contracts in Entity’s Own Equity (Subtopic 815-40) . The objective of this update is to simplify the accounting for convertible preferred stock by removing the existing guidance in ASC 470-20, Debt: Debt with Conversion and Other Options , (“ASC 470-20”), that requires entities to account for beneficial conversion features and cash conversion features in equity, separately from the host convertible debt or preferred stock. The guidance in ASC 470-20 applies to convertible instruments for which the embedded conversion features are not required to be bifurcated from the host contract and accounted for as derivatives. In addition, the amendments revise the scope exception from derivative accounting in ASC 815-40 for freestanding financial instruments and embedded features that are both indexed to the issuer’s own stock and classified in stockholders’ equity, by removing certain criteria required for equity classification. These amendments are expected to result in more freestanding financial instruments qualifying for equity classification (and, therefore, not accounted for as derivatives), as well as fewer embedded features requiring separate accounting from the host contract.
