Approach 1: Main Street Capital Excess Returns Analysis

The Excess Returns model looks at how efficiently Main Street Capital turns shareholder equity into earnings, then compares those returns with the cost of funding that equity. Instead of focusing on cash flows, it asks whether each dollar of equity is expected to earn more than it costs over time.

For Main Street Capital, the model uses a Book Value of US$33.46 per share and a Stable EPS of US$3.51 per share, based on weighted future Return on Equity estimates from 4 analysts. The Average Return on Equity is 11.47%, while the Cost of Equity is US$2.83 per share. That leaves an Excess Return of US$0.68 per share, indicating that the company is expected to earn more on its equity base than it costs to raise that equity. The Stable Book Value input of US$30.57 per share is drawn from the median Book Value over the past 5 years.

Combining these inputs, the Excess Returns model arrives at an estimated intrinsic value of about US$42.47 per share, which implies the stock is trading around 20.4% above this estimate at the current price of US$51.12.

Result: OVERVALUED

Approach 2: Main Street Capital Price vs Earnings

For a profitable company, the P/E ratio is a straightforward way to gauge how much you are paying for each dollar of earnings. It links the share price directly to the earnings that support dividends and potential reinvestment.

What counts as a “normal” P/E depends on how quickly earnings are expected to grow and how risky those earnings are. Higher growth or perceived resilience can justify a higher multiple, while slower growth or higher risk usually supports a lower one.

Main Street Capital currently trades on a P/E of 11.15x. That is well below the Capital Markets industry average P/E of 39.37x and also below the peer group average of 17.17x. Simply Wall St’s Fair Ratio for Main Street Capital is 11.12x. This Fair Ratio is a proprietary estimate of what the P/E should be after accounting for factors such as the company’s earnings growth profile, profit margins, risk characteristics, industry and market cap. Because it adjusts for these fundamentals, it tends to be more tailored than a simple comparison to peers or the broad industry.

With the actual P/E of 11.15x sitting very close to the Fair Ratio of 11.12x, the stock looks priced at about its estimated fair level on this metric.
