Insider and short-interest behaviour needs no valuation model.
MAIN's SEC filings give us limited machine-readable financials — common for some foreign or newly-listed filers that report under IFRS or file abbreviated statements. We can't run a full valuation on a partial dataset.
What to use instead: What we have parsed is shown below. As more complete filings arrive (or IFRS support lands), the valuation will populate.
How does MAIN stack up against its closest peers?
We take the 6 same-industry companies most similar to MAIN (similar size) and check what investors are paying for each dollar of their revenue (or profits). If MAIN is much more expensive on the same yardstick, that's a red flag — unless you have a specific reason it deserves a premium. For a leveraged business, FCF yield (in the table) is usually more reliable than EV/Sales, because revenue multiples ignore differences in margins and debt.
▾ What's "EV / Sales" in plain English?
EV (Enterprise Value) = market cap + total debt − cash. It's "what you'd pay to buy the entire company outright" — you pay the market cap to shareholders and take over their debt, but you keep their cash. EV is fairer than market cap alone because it includes the debt the new owner inherits.
EV / Sales = EV ÷ annual revenue. So "2.5×" means investors pay $2.50 of enterprise value per $1 of yearly sales. Higher = market is paying more per dollar of sales (usually because they expect future growth or fat margins).
p25 / median / p75 are the 25th, 50th (middle), and 75th percentile of the peers' multiples. Half the peers fall between p25 and p75. The median (p50) is the typical peer — that's the benchmark we compare to.
Bold middle number = median peer. Half the peers trade above it, half below. Computed over 6 same-industry peers; implausible multiples excluded.
⚠️ Important caveat: peer multiples only work if the peers are genuinely comparable. Always check the peer list below — if the auto-picker grabbed micro-caps or unrelated businesses, the comparison is noise. A medical-device giant priced against tiny biotech startups won't produce a useful signal.

A lender to private mid-market companies — not a bank
A BDC is a publicly-traded fund that lends money to private mid-market companies (typically $10M–$100M loans). They\'re structured like REITs — must distribute 90%+ of taxable income, so they pay big dividends. The right metrics are Price / Net Asset Value (P/NAV), dividend coverage, and the non-accrual rate (% of loans not paying interest). Standard bank metrics don\'t apply because BDCs don\'t take deposits.
- Non-accrual rate — % of loans not paying interest. Above 3% is yellow flag, above 5% is red. In the 10-K\'s "Schedule of Investments".
- Dividend coverage — Net Investment Income (NII) per share vs. distributions per share. Below 100% means they\'re paying out of capital.
- Leverage ratio — debt-to-equity. SEC caps BDCs at 2:1; most run 1.0-1.5×. Higher = more dividend but more risk.
- Originations vs repayments — Is the loan book growing or shrinking?
Quality & solvency checks
Cheap stocks can be cheap for a reason. These screens warn when a low valuation comes paired with structural fragility.
Why it matters: Cheap-looking stocks (low P/E or P/B) often have low Z-scores because the market knows the company is dying. Z-score warns you before you fall into a value trap.
Reference: > 3.0 = safe zone · 1.81–3.0 = grey zone · < 1.81 = distress zone
Full explanation →
BDCs are lenders — their balance sheets are loan portfolios funded with leverage, exactly the structure Altman Z misreads as distress. Judge them on Net Asset Value, the leverage ratio (capped at 2:1) and non-accrual rate instead.
Why it matters: High score = fundamentals improving. Low score = deteriorating. Especially powerful for filtering cheap stocks: cheap + high F-score historically outperforms; cheap + low F-score is often a value trap.
Reference: 7–9 = strong · 4–6 = mediocre · 0–3 = weak
Full explanation →
Piotroski F's checks (operating cash flow, gross-margin trend, current ratio, asset turnover) assume an industrial cost structure, so they misread asset-heavy or financial businesses like this one — a healthy REIT, utility, pipeline, BDC/fund or holding company can score low for reasons that aren't weakness. See the sector lens above for the metrics that actually matter.
A standard discounted cash flowDCF — Discounted Cash Flow — sums up all future cash a business will produce, adjusted for the fact that future dollars are worth less than dollars today.
Why it matters: It is the most fundamentally honest valuation method when applicable — but only works for companies with predictable, positive cash flow.
Reference: Best for: mature, profitable businesses. Fails for: pre-profit growth, banks, REITs.
Full explanation → (DCF) valuation is not meaningful for Main Street Capital CORP because the model projects negative equity value under current assumptions, and operating cash flow has been negative in the latest period, only positive in 1 of the last 5 years. Investors are likely focused on the company's ability to generate consistent positive operating cash flow and manage its rising long-term debt. The market may be assigning value to the potential for strategic acquisitions and portfolio company growth, which is not fully captured in the backward-looking model. The number one quantifiable risk is the continued rise in long-term debt.

Anatomy of a share
What you're buying per share. Bars are at the same scale so you can see the relative size of revenue, costs, cash flow, and debt — not just read them in a table.
What's free cash flow / what do these mean?
Revenue per share — how much the business earns from customers, divided by the number of shares outstanding. Top of the income statement.
Earnings per share — profit left after operating costs, interest, and taxes, per share. Two versions appear on this page and are not interchangeable: GAAP diluted EPS uses the company's weighted-average diluted share count during the reporting period (this is the "earnings" in "price-to-earnings"); net income per current share divides annual net income by today's share count. They differ whenever the share count has changed.
Owner-earnings free cash flow per share — the cash the business produces for shareholders. Savng's owner-earnings FCF subtracts capital expenditures and stock-based compensation from operating cash flow (SBC is a real dilution cost even though it's non-cash). This is deliberately more conservative than "standard" FCF, which subtracts only capital expenditures — so our figure is lower than the headline FCF you'll see elsewhere. FCF funds dividends, buybacks, debt repayment, and acquisitions; a company can report positive earnings yet negative FCF.
Debt per share — total interest-bearing borrowings divided by shares. High debt-per-share next to thin FCF-per-share is a fragility signal.
What you actually need to decide
Every stock price is a disagreement. Here's the single thing that must go right for the bulls, the single thing that breaks the thesis, and the concrete signposts to watch so you can update your view as real results arrive.
- Next quarter's operating cash flow trend
- Changes in long-term debt levels
- Announcements of new investment originations or exits
The trend, in plain numbers (FY2024 → FY2025, latest reported)
Straight from the financial statements — no model, no opinion. For a small or unprofitable company, the direction of these numbers usually tells you more than any single valuation.
- Free cash flow is negative at -$67.1M — the cash burn narrowed vs last year.
- Net income fell -3% to $493.4M.

Why Is It Priced Like This?
Why Customers Pay
What we use instead: earnings (P/E, EV/EBIT), book value (P/B) — computed from the figures this company does report, shown in the sections below. Those numbers are unaffected by the missing cash-flow data.
The market is pricing MAIN based on its consistent profitability (net income positive latest, profitable 5/5 yrs) despite negative operating cash flow. Investors are likely focused on the company's ability to generate future investment income and potential for portfolio company exits. The market may be assigning value to the company's expertise in identifying and nurturing growth-oriented private companies, which is not in the model.
Business Model & Valuation
How They Make Money
The company funds itself through a combination of debt, equity raises, and retained earnings, with long-term debt rising from $1796M to $2458M.
Growth / Revenue DCF
Negative free cash flow: revenue/margin growth model used - standard FCF DCF is unreliable for companies still scaling.

What this model does NOT do: this is a consolidated owner-earnings FCF model. Standalone segment assumptions: none. It does not project its revenue segments independently; their combined effect is embedded in the historical revenue and cash-flow trend the model extrapolates. The calculator above can only approximate a segment's impact through the single consolidated growth rate — it cannot model any one line separately. For a true segment-level view, build a separate model from the company's segment disclosures.
Maturity & Competitive Position
Moat Signals
Net income has been positive in the latest period and for 5 out of 5 years, while operating cash flow has been negative in the latest period.

Market Signals
These are timing signals, not value signals — they describe the stock's recent price behavior, not what the business is worth. Use them for the "the thesis looks good, but is now the moment?" question. Each tile below explains what it's saying.
Why it matters: Short-term contrarian indicator. Extreme readings often precede mean reversion, though not always.
Reference: 30–70 normal · >70 overbought · <30 oversold
Full explanation → (14)43.3NeutralMomentum is balanced — neither overbought nor oversold.
Why it matters: When the fast line crosses above the slow line, short-term momentum is turning up; below, turning down. A timing cue, not a value signal.
Reference: Line above signal = bullish momentum · below = bearish
Full explanation →BearishLine below signalThe fast trend is below the slow trend — short-term momentum is currently downward.
Technicals describe price, not the business. A great company can have a "bearish" tape (a buying chance) and a weak one a "bullish" tape (a trap). Pair these with the valuation and health sections above.

Guardrail Notes (3)
- FCF negative: revenue/margin growth model projects future cash flows from revenue trajectory.
- INVARIANT: weighted IV is non-positive. Model may not be appropriate.
- Model implies no positive equity value under these assumptions. Valuation is speculative/low-confidence.

Cash Flow (5yr)
Capital expenditure isn't tagged in this filer's machine-readable data (the CapEx column shows "—"). The free-cash-flow column is therefore operating cash flow less stock-based compensation only — an upper bound on true owner earnings, not the real figure. Companies that report capex under a custom label (some large IFRS filers do) look better here than they are.
| Year | Operating CF | CapEx | − SBC & adj. | Free Cash Flow |
|---|---|---|---|---|
| 2025 | -45.7M | — | 21.4M | -67.1M |
| 2024 | -87.1M | — | 18.8M | -105.9M |
| 2023 | 285.3M | — | 16.5M | 268.8M |
| 2022 | -246.9M | — | 13.6M | -260.6M |
| 2021 | -515.4M | — | 10.9M | -526.3M |
How we define FCF: operating cash flow − capital expenditure − stock-based compensation (owner-earnings basis — SBC is a real cost to shareholders even though it's non-cash). Latest year: -45.7M − — − 21.4M (SBC & adj.) = -67.1M. This is the same owner-earnings FCF definition the valuation model uses, though the DCF's starting value is a projected from revenue × terminal margin, not this single year.
