Sunrun Inc.

Investing in our common stock involves numerous risks, including the risks described in Part II, Item 1A. “Risk Factors”, of this Quarterly Report on Form 10-Q. Below are some of these risks, any one of which could materially adversely affect our business, financial condition, results of operations and prospects.

Selected Risks Related to the Battery and Solar Industry

•The battery storage and solar energy industry is an emerging market which is constantly evolving and may not develop to the size or at the rate we expect.

•We have historically benefited from declining costs in our industry, and our business and financial results may be harmed as a result of recent, and any continued increases in, costs associated with our battery and solar service offerings and any failure of these costs to continue declining as we currently expect. If we do not reduce our cost structure in the future, our ability to continue to be profitable may be impaired.

•We face competition from traditional energy companies as well as battery, solar, and other renewable energy companies.

Selected Risks Related to Our Operating Structure and Financing Activities

•We need to raise capital to finance the continued growth of our operations and solar service business. If capital is not available to us on acceptable terms, as and when needed, our business and prospects would be materially and adversely impacted. In addition, our business is affected by general economic conditions and related uncertainties affecting markets in which we operate. Volatility in current economic conditions could adversely impact our business, including our ability to raise financing.

•Volatility and increases in interest rates raise our cost of capital and may adversely impact our business.

•We expect to incur substantially more debt in the future, which could intensify the risks to our business.

Selected Risks Related to Regulation and Policy

•The customer value proposition for distributed solar, storage, and home electrification products is influenced by a number of factors, including, but not limited to, the retail price of electricity, the valuation of electricity not consumed on site and exported to the grid, the rate design mechanisms of customers’ utility bills, various policies related to the permitting and interconnection costs of our products to homes and the grid, the availability of incentives for solar, batteries, and other electrification products, and other policies which allow aggregations of our systems to provide the grid value. Significant changes to any of these factors may impact the competitiveness of our service offerings to customers.

•Electric utility statutes and regulations and changes to such statutes or regulations may present technical, regulatory, and economic barriers to the purchase and use of our solar service offerings that may significantly reduce demand for such offerings.

•Regulations and policies related to rate design could deter potential customers from purchasing our solar service offerings, reduce the value of the electricity our systems produce, and reduce any savings that our customers could realize from our solar service offerings.

•Trade policies and international relations between the U.S. and key solar manufacturing countries continue to evolve. The imposition of new duties, tariffs, or other trade barriers—whether by the U.S. government or in retaliation by other nations—may disrupt supply chains, increase costs, and create uncertainty in our business operations.

Selected Risks Related to Our Business Operations

•Our growth depends in part on the success of our relationships with third parties, including our solar partners.

•We and our solar partners depend on a limited number of suppliers of solar panels, batteries, and other system components to adequately meet anticipated demand for our solar and storage service offerings. Any shortage, bottlenecks, delay, detentions, or component price change from these suppliers, or the acquisition of any of these suppliers by a competitor, could result in sales and installation delays, cancellations and loss of market share.

•If we fail to manage our recent and future growth effectively, we may be unable to execute our business plan, maintain high levels of customer service, or adequately address competitive challenges.

•We may not realize the anticipated benefits of past or future investments, strategic transactions, or acquisitions, and integration of these acquisitions may disrupt our business and our management team.

•The failure to hire and retain a sufficient number of employees and service providers in key functions would constrain our growth and our ability to timely complete customers’ Projects and successfully manage customer accounts.

•Regulators may impose rules on the type of electricians qualified to install and service our solar and battery systems in California, which may result in workforce shortages, operational delays, and increased costs.

•Our results of operations may fluctuate from quarter to quarter, which could make our future performance difficult to predict and could cause our results of operations for a particular period to fall below expectations, resulting in a decline in the price of our common stock.

•Our actual financial results may differ materially from any guidance we may publish from time to time.

•Failure or perceived failure to comply with existing or future laws, regulations, contracts, self-regulatory schemes, standards, and other obligations related to data privacy and security (including security incidents) could harm our business. Compliance or the actual or perceived failure to comply with such obligations could increase the costs of our products/services, limit their use or adoption, and otherwise negatively affect our operating results and business.

Selected Risks Related to Taxes and Accounting

•Our ability to provide our battery and solar service offerings to customers on an economically viable basis depends in part on our ability to finance these systems with fund investors who seek particular tax and other benefits.

•If the IRS makes determinations that the creditable basis of our solar energy systems is materially lower than what we have claimed, we may have to pay significant amounts to our fund investors, and our business, financial condition, and prospects may be materially and adversely affected.

•Our business currently depends in part on the availability of utility rebates, tax credits and other benefits, tax exemptions and exclusions, and other financial incentives, on the federal, state, and/or local levels. We may be adversely affected by changes in, and application of, these laws or other incentives to us, and the expiration, elimination or reduction of these benefits could adversely impact our business.

If we are unable to adequately address these and other risks we face, our business may be harmed.
