EXHIBIT 99.1

GENERAL MOTORS FINANCIAL COMPANY, INC.

UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

On March 5, 2017, General Motors Holdings LLC (the “Seller”), a wholly owned subsidiary of General Motors Company (the “Parent”) and the parent of General Motors Financial Company, Inc. (the “Company”), entered into a Master Agreement (the “Agreement”) with Peugeot S.A. (the “Purchaser”). Pursuant to the Agreement, the Purchaser will acquire, together with a financial partner, the Seller’s European financial subsidiaries and branches (collectively, the “European Operations”), as well as the Parent’s Opel and Vauxhall businesses and certain other assets in Europe (the “Opel/Vauxhall Business” and, together with the European Operations, the “Transferred Business”).

The net consideration to be paid for the European Operations will be 0.8 times their book value at closing, which the Company estimates will be approximately $1 billion, denominated in Euros. The purchase price is subject to certain adjustments as provided in the Agreement. The Company expects to recognize a disposal loss of up to $700 million based on current foreign currency exchange rates.

The transfer of the Transferred Business is subject to the satisfaction of various closing conditions, including receipt of necessary antitrust, financial and other regulatory approvals, the reorganization of the Transferred Business, including pension plans in the United Kingdom, the completion of the contribution or sale by Adam Opel GmbH of its assets and liabilities to a subsidiary, the transfer of GMAC UK plc’s interest in SAIC-GMAC Automotive Finance Company Limited to the Company or an alternate entity designated by the Seller, unless either party elects to close without completion of the transfer, and the continued accuracy, subject to certain exceptions, at closing of certain of the Seller’s representations and warranties. There can be no assurance that all required governmental consents or clearances will be obtained or that the other closing conditions will be satisfied. The transfer of the Opel/Vauxhall Business is expected to close by the end of 2017 and the transfer of the European Operations is expected to close as soon as practicable after the receipt of necessary antitrust, financial and other regulatory approvals, which may be after the transfer of the Opel/Vauxhall Business, but not before. The transfer of the European Operations will not occur unless the transfer of the Opel/Vauxhall Business occurs.

The Agreement contains certain termination rights for both the Seller and the Purchaser, including if certain closing conditions with respect to the transfer of the Opel/Vauxhall Business have not been satisfied on or before June 1, 2018.

The Seller and the Purchaser have each made customary representations, warranties and covenants in the Agreement, including, among others, covenants by the Seller to conduct the Opel/Vauxhall Business and the business of the European Operations in the ordinary course between the execution of the Agreement and the consummation of the transaction.

The following unaudited pro forma condensed consolidated balance sheet of the Company as of March 31, 2017 is presented as if the sale of the European Operations, as described in the notes to these unaudited pro forma condensed consolidated financial statements, had occurred at March 31, 2017.

NOTES TO THE UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Disposition of European Operations

The pro forma adjustments include the reversal of (i) the historical assets and liabilities and results of operations of the European Operations, including the related tax impact and consolidation entries and (ii) certain previously eliminated transactions between the European Operations and subsidiaries of the Company, as a result of the completion of the disposition.

The pro forma adjustments on the condensed consolidated balance sheet also include the expected proceeds and loss on disposal, as well as proceeds from expected dividends to be paid by the European Operations in order to bring their leverage ratio to within targeted levels, as defined in the Agreement. The estimated loss is not included in the pro forma adjustments on the pro forma consolidated statements of income as it is considered to be nonrecurring in nature.

The pro forma adjustments to the condensed consolidated balance sheet do not include adjustments for any dividends that may be paid to by the Company to the Parent following the completion of the disposition.
