SLM Corporation is a holding company, which operates through various subsidiaries and is a financial brand for higher education. Co.'s primary business is to originate and service loans it makes to students and their families to finance the cost of their education. It also offers a range of deposit products insured by the Federal Deposit Insurance Corporation.

We show 66 historical shares outstanding datapoints in our SLM shares outstanding history coverage, used to compute SLM market cap on those dates.

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