SUM split history picture
Summit Materials (SUM) has 2 splits in our SUM split history database. The first split for SUM took place on December 07, 2017. This was a 1014 for 1000 split, meaning for each 1000 shares of SUM owned pre-split, the shareholder now owned 1014 shares. For example, a 1000 share position pre-split, became a 1014 share position following the split. SUM's second split took place on December 14, 2022. This was a 1017 for 1000 split, meaning for each 1000 shares of SUM owned pre-split, the shareholder now owned 1017 shares. For example, a 1014 share position pre-split, became a 1031.238 share position following the split.

When a company such as Summit Materials splits its shares, the market capitalization before and after the split takes place remains stable, meaning the shareholder now owns more shares but each are valued at a lower price per share. Often, however, a lower priced stock on a per-share basis can attract a wider range of buyers. If that increased demand causes the share price to appreciate, then the total market capitalization rises post-split. This does not always happen, however, often depending on the underlying fundamentals of the business.

Looking at the SUM split history from start to finish, an original position size of 1000 shares would have turned into 1031.238 today. Below, we examine the compound annual growth rate — CAGR for short — of an investment into Summit Materials shares, starting with a $10,000 purchase of SUM, presented on a split-history-adjusted basis factoring in the complete SUM split history.
