Item  8.01 Other Events.

On October 1, 2021, a subsidiary of Opendoor Technologies Inc. (the “Company”) entered into an amended and restated mezzanine term debt facility, with $3.0 billion in maximum borrowing capacity and a final maturity date of April 1, 2026. This non-recourse facility refinances the previously outstanding mezzanine term debt facilities on substantially similar economic terms.

This facility, combined with other recent amendments, upsizes and additions to existing debt facilities, more than doubles the total borrowing capacity of the Company’s subsidiaries since June 30, 2021 to $8,980.0 million across their non-recourse, asset-backed facilities (of which $6,088.5 million is fully committed). These figures compare to $4,304.0 million of total borrowing capacity (of which $2,506.7 million was fully committed) as of June 30, 2021, and $3,354.0 million of total borrowing capacity (of which $1,932.0 million was fully committed) as of December 31, 2020.
