Question 1

What is Main Street Capital's P/E ratio?

Accepted Answer

Main Street Capital (MAIN) P/E ratio is 11.0× as of June 5, 2026. The ratio is calculated by dividing market capitalisation by trailing twelve-month earnings (net income), using USD-normalised financials (IAS 21 exchange-rate translation for non-USD reporters).

Question 2

How is the P/E ratio calculated?

Accepted Answer

P/E = Share Price ÷ Trailing Twelve-Month (TTM) Diluted EPS, or equivalently Market Capitalisation ÷ TTM Net Income. All inputs are sourced from audited GAAP/IFRS filings and translated to USD using period-end exchange rates so the multiple is comparable across companies and currencies.

Question 3

What is the P/E ratio?

Accepted Answer

The price-to-earnings (P/E) ratio, also called the earnings multiple, measures how much investors pay per dollar of a company's trailing twelve-month (TTM) earnings. It is calculated as share price ÷ TTM diluted EPS (equivalent to market capitalisation ÷ TTM net income). A higher P/E implies the market is pricing in stronger future earnings growth or lower risk; a lower P/E can signal slower expected growth, higher risk, or potential undervaluation.

Question 4

What is a good P/E ratio for Main Street Capital?

Accepted Answer

There is no universal "good" P/E. As a rule of thumb, the S&P 500 has historically averaged a P/E in the mid-to-high teens; mature, slow-growth businesses commonly trade in the 10–18× range, while high-growth or asset-light companies often trade at 25–50×+. What matters is the comparison to sector peers and to the company's own historical range. For Main Street Capital specifically, the relevant sector benchmark is the current sector median of 12.8×.

Question 5

Is Main Street Capital's P/E ratio high or low?

Accepted Answer

Main Street Capital's P/E ratio of 11.0× is above its own 5-year average of 10.0× and below the sector median of 12.8×. That places the current reading at the 77th percentile of its 10-year history. A higher multiple usually reflects stronger expected growth, lower perceived risk, or higher returns on capital; a lower multiple reflects the opposite.

Question 6

What is Main Street Capital's historical P/E ratio range?

Accepted Answer

In the available daily series, Main Street Capital (MAIN) P/E ratio has ranged from a low of 7.3× in 2022 to a high of 73.4× in 2020. The 5-year average is 10.0× and the 5-year median is 9.7×.

Question 7

What was Main Street Capital's P/E ratio in 2025?

Accepted Answer

Main Street Capital (MAIN) P/E ratio at the end of 2025 was 11.0×. Annual values reflect the multiple on the last trading day of each calendar year, using the trailing twelve-month earnings figure available at that date.

Question 8

Why does Main Street Capital's P/E ratio change over time?

Accepted Answer

Valuation multiples move with two inputs: the numerator (market capitalisation, which tracks the share price) and the denominator (earnings). Share-price changes — driven by interest rates, earnings expectations, risk appetite, and broader market sentiment — typically dominate short-term moves, while changes in the underlying fundamental drive the longer-term trend. As a result, the ratio can rise during stock-price rallies even if the business itself has not become more valuable, and fall during sell-offs even when fundamentals are improving.
