Approach 1: Main Street Capital Excess Returns Analysis

The Excess Returns model looks at how effectively a company turns its equity base into profits above the return that shareholders require. Instead of focusing on cash flows, it measures the spread between return on equity and the cost of equity, then projects how long that spread might persist.

For Main Street Capital, the model uses a Book Value of $33.33 per share and a Stable EPS of $5.27 per share, based on the median return on equity from the past 5 years. The estimated Cost of Equity is $2.76 per share, which implies an Excess Return of $2.51 per share. The Average Return on Equity used in the model is 17.68%, with a Stable Book Value assumption of $29.80 per share, based on the median book value from the past 5 years.

Feeding these inputs into the Excess Returns framework produces an estimated intrinsic value of $73.66 per share. Compared with the recent share price of $57.36, this model implies the stock is 22.1% undervalued.

Result: UNDERVALUED

Our Excess Returns analysis suggests Main Street Capital is undervalued by 22.1%. Track this in your watchlist or portfolio, or discover 51 more high quality undervalued stocks.

Approach 2: Main Street Capital Price vs Earnings

For a profitable company like Main Street Capital, the P/E ratio is a useful way to think about what you are paying for each dollar of current earnings. It gives a quick read on how the market is weighing those earnings against factors such as stability, growth potential, and risk.

In general, higher expected growth and lower perceived risk can justify a higher P/E, while slower growth or higher risk usually means a lower, more conservative P/E makes sense. Main Street Capital trades on a P/E of 10.48x. This compares with an industry average P/E of 42.58x for Capital Markets stocks and a peer average of 14.17x.

Simply Wall St also provides a “Fair Ratio” of 9.95x. This is a proprietary estimate of what P/E might be reasonable for Main Street Capital, given factors such as its earnings profile, industry, profit margins, market value and risk characteristics. Because it is tailored to the company, it can be more informative than a simple comparison with broad industry or peer averages. With the current P/E of 10.48x sitting slightly above the Fair Ratio of 9.95x, the shares screen as modestly overvalued on this metric.

Result: OVERVALUED

Upgrade Your Decision Making: Choose your Main Street Capital Narrative

Earlier it was mentioned that there is an even better way to understand valuation, so Narratives on Simply Wall St let you attach a clear story about Main Street Capital to hard numbers by linking your view of its revenue, earnings and margin outlook to a financial forecast. This converts that into a fair value and compares it with the current price to help you judge whether the stock looks appealing or stretched. It then keeps that view updated automatically as new earnings, news and analyst targets arrive. One investor might build a Narrative around the higher analyst price target of US$70.00 with assumptions closer to the more optimistic US$473.4 million earnings estimate, while another might anchor on the lower US$58.00 target and US$311.6 million earnings estimate.
