Prior to the Closing of the transaction with Zanite, Eve Sub was managed, operated, and funded by Embraer. Accordingly, certain shared costs have been allocated to Eve and reflected as expenses in Eve's stand-alone condensed consolidated financial statements. In December 2021, Embraer started charging research and development (“R&D”) and general and administrative (“G&A”) expenses to Eve through the Master Service Agreement (“MSA”) and Shared Service Agreement (“SSA”), respectively. The expenses reflected in the condensed consolidated financial statements may not be indicative of expenses that will be incurred by Eve in the future.

Corporate Costs Embraer incurs corporate costs for services provided to Eve. These costs include, but are not limited to, expenses for information systems, accounting, treasury, purchasing, human resources, legal, and facilities. These costs benefit Eve, but are not covered under the MSA or SSA. The corporate costs are allocated to the “Research and development” and “Selling, general and administrative” line items of the condensed consolidated statements of operations as appropriate.

Transaction Costs During the six months period ended June 30, 2022, Embraer paid for Transaction Costs attributable to Eve Sub. The Transaction Costs comprise, but were not limited to, costs associated with legal, finance, consulting, and auditing services with the objective to effectuate the transaction with Zanite, as described in Note 1. Expenses directly related to the anticipated closing of the transaction with Zanite were capitalized and the remaining expenses were charged to the statement of operations as SG&A expenses.

Master Service Agreement and Shared Service Agreement In connection with the transfer of the assets and liabilities of the UAM business to Eve Sub, Embraer and Eve Sub entered into the MSA and SSA on December 14, 2021. The initial terms for the MSA and SSA are 15 years. The MSA can be automatically renewed for additional successive one-year periods. The MSA established a fee so that Eve may have access to Embraer’s R&D and engineering department structure, as well as, at Eve’s option, the ability to access manufacturing facilities in the future. The SSA established a cost overhead pool to be allocated, excluding any margin, so that Eve may be provided with access to certain of Embraer’s administrative services and facilities such as shared service centers. In addition, on December 14, 2021, Eve Sub entered into a MSA with Atech Negócios em Tecnologias S.A., a Brazilian corporation (sociedade anônima) (“Atech”) and wholly owned subsidiary of Embraer, for an initial term of 15 years (the “Atech MSA”). Fees under the Atech MSA are charged to Eve for services related to Air Traffic Management, defense systems, simulation systems, engineering, and consulting services.

Fees and expenses in connection with the MSA are set to be payable within 45 days after receipt of the invoice by Eve together with documentation supporting the fees and expenses. Costs and expenses incurred in connection with the provision of shared services to Eve pursuant to the SSA are set to be payable within 45 days of receipt by Eve. Services provided under the MSA and SSA are recognized in Related party payables within the condensed consolidated balance sheets.

Related Party Receivables and Payables Certain employees have transferred from Embraer to Eve. On the transfer date of each employee, all payroll related accruals for the employee are transferred to Eve. Embraer is responsible for payroll related costs prior to the transfer date. Eve recognizes a related party receivable from Embraer for payroll costs incurred prior to the transfer date. Additionally, Embraer transferred certain liabilities related to the Eve business, which led to the recognition of a receivable from EAH. This receivable balance is decreased when Embraer pays for corporate expenses (e.g., health insurance) on behalf of Eve.

Royalty-Free Licenses Under the MSA and SSA, Eve has a royalty-free license to access Embraer’s intellectual property to be used within the UAM market.

Leases Eve enters into agreements with Embraer to lease corporate office space and other facilities. Refer to Note 17.

Related Party Loan On August 1, 2022, the Company entered into a loan agreement (the “Loan Agreement”) with EAH, a wholly owned U.S. subsidiary of Embraer, in order to efficiently manage the Company’s cash at a rate of return that is favorable to the Company. Pursuant to the Loan Agreement, the Company agreed to lend to Embraer an aggregate principal amount of up to $81,000,000 at an interest rate of 4.89% per annum. All unpaid principal and any accrued and unpaid interest thereon, shall be due and payable on August 1, 2023. The date may be extended upon mutual written agreement by the Company and Embraer. Any outstanding principal amount under the Loan Agreement may be prepaid at any time, in whole or in part, by EAH at its election and without penalty. The Company may request full or partial prepayment of any outstanding principal amount under the Loan Agreement at any time.
