Sunrun Inc. is a home solar, battery storage, and energy services company. Co. is engaged in the design, development, installation, sale, ownership and maintenance of residential solar energy systems (Projects) in the U.S.. Its primary customers are residential homeowners. Co. also offers battery storage along with solar energy systems to its customers in select markets and sells its services to certain commercial developers through its multifamily and new homes offerings. Co. installs solar energy systems on its customers' homes and provides them with the solar power produced by those systems for a 20- or 25-year initial term. We show 45 historical shares outstanding datapoints in our RUN shares outstanding history coverage, used to compute RUN market cap on those dates.

Understanding the changing numbers of shares outstanding, the changing share price, and the resulting changing RUN market cap history over the course of time is important for investors interested in comparing RUN's market cap history versus its peers. Many "beginner" or "novice" investors will look at one stock trading at a price of $10 per share and another trading at a price of $20 per share and think the latter company is worth twice as much. Of course, that is a completely meaningless comparison without also knowing how many shares outstanding there are for each of the two companies, and then calculating their respective market caps. Comparing the share price of RUN versus a peer is one thing; comparing RUN market cap versus a peer is a completely different story. Furthermore, via fluctuation both in per-share price and in the number of shares outstanding (via issuance of new shares over time, the repurchase of existing shares), the market cap for a company like RUN can fluctuate over the course of history. With this page we aim to empower investors researching RUN by allowing them to research the RUN market cap history.
