| About AAON, Inc. |
| AAON, Inc. is a producer of heating, ventilation, and air conditioning (HVAC) systems for commercial and industrial indoor environments. Co. operates through three segments: AAON Oklahoma, AAON Coil Products, and BASX. The AAON Oklahoma segment engineers, manufactures, and sells, semi-custom, and custom HVAC systems, designs and manufactures control solutions, and sells retail parts to customers through retail part stores and online. AAON Coil Products segment engineers and manufactures a selection of semi-custom and custom HVAC systems as well as a variety of heating and cooling coils to be used in HVAC systems. We show 69 historical shares outstanding datapoints in our AAON shares outstanding history coverage, used to compute AAON market cap on those dates. Understanding the changing numbers of shares outstanding, the changing share price, and the resulting changing AAON market cap history over the course of time is important for investors interested in comparing AAON'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 AAON versus a peer is one thing; comparing AAON 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 AAON can fluctuate over the course of history.
