Gibraltar Industries is a manufacturer and provider of products and services for the renewable energy, conservation, residential, industrial and infrastructure markets. Co.'s segments include: Renewable Energy and Conservation, which is a designer and manufacturer of solar mounting systems and greenhouse structures and botanical oil extraction systems; Residential Products, which services the residential repair and remodeling and to a lesser extent the housing construction markets in North America with products; and Industrial and Infrastructure Products, which serves various end markets such as industrial and commercial construction, automotive, airports and energy and power generation. We show 50 historical shares outstanding datapoints in our ROCK shares outstanding history coverage, used to compute ROCK market cap on those dates.

Understanding the changing numbers of shares outstanding, the changing share price, and the resulting changing ROCK market cap history over the course of time is important for investors interested in comparing ROCK'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 ROCK versus a peer is one thing; comparing ROCK 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 ROCK can fluctuate over the course of history. With this page we aim to empower investors researching ROCK by allowing them to research the ROCK market cap history.
