Organization and Description of Business	Organization and Description of Business Description of Business: Spruce Power Holding Corporation (formerly known as XL Fleet Corp.) and its subsidiaries ("Spruce Power" or the “Company”) is a leading owner and operator of distributed solar energy assets across the United States, offering subscription-based services to approximately 72,000 customers and making renewable energy more accessible to everyone. The Company generates revenues primarily through the sale of electricity generated by its residential solar energy systems to homeowners pursuant to long-term agreements that obligate the Company’s subscribers to make recurring monthly payments, and the servicing of those agreements for other institutional owners of residential solar energy systems. In addition, the Company also generates cash flows and earns interest income from the investment made during the first quarter of 2023 under the master lease with SS Holdings 2017, LLC and its subsidiaries ("SEMTH"). The Company holds subsidiary fund companies that own and operate portfolios of residential solar energy systems. The solar energy systems are subject to solar lease agreements ("SLAs") and power purchase agreements ("PPAs", together with the SLAs, "Customer Agreements") with residential customers who benefit from the production of electricity produced by the solar energy systems. The solar energy systems may qualify for subsidies, renewable energy credits and other incentives as provided by various states and local agencies. These benefits have generally been retained by the Company's subsidiaries that own the systems, with the exception of the investment tax credit under Section 48 of the Internal Revenue Code ("IRC"), which were generally passed through to the various financing partners of the solar energy systems. The Company also engages in the energy efficiency and solar loan servicing. The Company offers services which include asset management services and operating and maintenance services for residential solar photovoltaic projects, in addition to, loan servicing support that allows residential consumers to finance energy efficiency home improvements and residential solar energy systems. Discontinued Operations: Historically the Company had provided fleet electrification solutions for commercial vehicles in North America, offering its systems for vehicle electrification (the “Drivetrain” segment) and through its energy efficiency and infrastructure solutions business, including offering and installing charging stations to enable customers to effectively and cost effectively develop the charging infrastructure required for their electrified vehicles (the “XL Grid” segment). In the first quarter of 2022, the Company initiated a strategic review of its overall business operations which included assessing its offerings, strategy, processes and growth opportunities. As a result of the strategic review, in the first quarter of 2022 the Company made the following decisions relating to a restructuring of its Drivetrain business: (i) the elimination of a substantial majority of the Company’s hybrid drivetrain products; (ii) the elimination of its Plug-In Hybrid Electric Vehicles (“PHEV”) products; (iii) the reduction in the size of the Company’s workforce by approximately 50 employees; (iv) the closure of the Company’s production center and warehouse in Quincy, IL; (v) the closure of the Company’s engineering activities in its Boston office; and (vi) the termination of the Company’s partnership with eNow. Following the strategic review, the Company announced its decision to pursue transformational mergers and acquisition (“M&A”) opportunities, enabled by a significant cash balance resulting from the Company’s go-public transaction completed in December 2020. This included the implementation of a process to institutionalize the M&A effort including the formation of an investment committee comprised of senior members of our team and members of the Board. The objective was to continue the exploration of value-generative opportunities in the decarbonization and energy transition ecosystem, focused on three core requirements, (i) a business that is making an impact on decarbonization, (ii) a leader in an established, growing market segment, and (iii) a company that is generating positive EBITDA. As a result of these efforts, on September 9, 2022, the Company acquired 100% of the membership interests of Spruce Holding Company 1 LLC, Spruce Holding Company 2 LLC, Spruce Holding Company 3 LLC, and Spruce Manager LLC (collectively and together with their subsidiaries, “Legacy Spruce Power or Spruce Power”) (See Note 3. Business Combinations). Spruce Power was one of the largest privately held owner and operator of residential solar energy systems in the U.S. at the time of the transaction, with approximately 51,000 customer subscribers as of December 31, 2022. Spruce Power sells the power generated by its systems to homeowners pursuant to long-term agreements that obligate subscribers to make recurring monthly payments. With the completion of the acquisition of Spruce Power, the Company announced that it would analyze strategic alternatives related to its Drivetrain business. In December 2022, the Company announced that it was exiting its Drivetrain business and would be selling a portion of the business for an immaterial amount to Shyft Group USA (“Shyft”) which closed in January 2023. Shyft bought certain technical equipment and assumed the Company’s Wixom, Michigan facility and also offered employment to certain engineers and other sales personnel. Shyft also assumed completion of the Company’s pilot development agreement with the Department of Defense related to vehicle hybridization (with the Company retaining rights to potential future royalties from the program). In the fourth quarter, the Company also announced that it had sold certain battery inventory and its legacy hybrid technology to RMA Group, an automotive and equipment supplier in Southeast Asia. As of December 31, 2022, the Company ceased Drivetrain operations and began to restructure most of its related Corporate functions. The Company also began reviewing the operations of its XL Grid business to evaluate its strategic fit with Spruce Power. In the fourth quarter of 2022, the Company entered into a non-binding letter of intent (“LOI”) for the sale of World Energy for an immaterial amount, with the divestiture closing in January 2023 and the Company ceased XL Grid operations after the closing of the divestiture. Both the Drivetrain and XL Grid operations are presented as discontinued operations in the Unaudited Condensed Consolidated Financial Statements.
