What MGIC INVESTMENT CORP reports
Revenue and net income below are for fiscal period FY2025, the period label carried by this company’s own annual XBRL filings to the SEC. Fiscal years do not line up between companies — one company’s FY2026 can cover much the same months as another’s FY2025 — so compare the periods, not just the numbers.
Where the employee count comes from
Headcount comes from Yahoo Finance, not from a filing. The date beside it is the day we retrieved the figure — it is not the date the company counted its staff, and Yahoo does not publish that date. Unlike the SEC filings behind the other figures on this page, this one carries no open licence, so we publish the number and nothing else from that source.
Insiders at MGIC INVESTMENT CORP
Shares is what each person last reported holding here.
Everyone below has filed at least one insider report against this company.
Value is that share count priced at the same closing price used everywhere else on this site. A row priced from only some of a person’s securities says so — we do not quietly present a partial sum as a complete one.
Rows are grouped by the role each person reports.
The role comes from the relationship boxes a person ticks on their own insider filings — officer, director, ten per cent owner — not from anything we infer. Somebody who is both an officer and a director appears once, in the combined group, so the row count still matches the figure at the top of this page. Where no filing states a role we say so instead of guessing one.

Recent insider transactions
Of the 198 rows we hold, 0 are open-market purchases and 33 open-market sales (S) — the only codes we count as buying or selling.
The rest — awards, shares withheld to pay tax, option exercises, gifts and so on — follow from an employment contract or a transfer arranged off-market, not from a decision to buy or sell, so counting them would turn this into a pay table.
A price of 0.00 is a real reported figure on gifts (G) and share awards (A) — not a gap in our data.

From SEC Form 4 filings. Every row links to the filing it came from. How we calculate this.
What a Form 4 is
The report an officer, director or large shareholder must file after trading their own company’s stock.
Subsidiaries — 9 legal entities
Subsidiaries of MGIC INVESTMENT CORP
9 legal entities named in the subsidiary exhibit filed with this company’s most recent 10-K. . Filing on SEC.gov.
This is not the full list. SEC rules only require a company to name its significant subsidiaries.
What that leaves out
Smaller entities are left out of the exhibit entirely. A short list here means a short exhibit — it does not mean the company owns nothing else. Nothing on this page is inferred: every name below is copied from the filing.
| Subsidiary | Organised in |
|---|---|
| MGIC Assurance Corporation | — |
| MGIC Credit Assurance Corporation | — |
| MGIC Indemnity Corporation | — |
| MGIC Insurance Services Corporation | — |
| MGIC Investor Services Corporation | — |
| MGIC Mortgage and Consumer Asset I, LLC (2) | — |
| MGIC Mortgage Services, LLC | — |
| MGIC Reinsurance Corporation of Vermont (3) | — |
| Mortgage Guaranty Insurance Corporation | — |
What counts as a subsidiary
A subsidiary is a separate legal entity this company controls; it is not the same thing as a brand, a division or an office. These entities do not file with the SEC in their own right, so there is no separate page to open for them.

Sources and technical notes
Every figure on this page comes from filings to the U.S. SEC via EDGAR. Nothing here is estimated, and nothing is taken from press coverage or company websites.
Share count: cover page of the latest filing (dei:EntityCommonStockSharesOutstanding), taken from
MGIC INVESTMENT CORP’s own filings and multiplied by our closing price.
Full method.
What that share count means
the share count the company itself prints on the cover of its most recent filing, as of the date it signed that filing.
We do not take a market cap from a data vendor, and we do not estimate one: the figure is a share count from MGIC INVESTMENT CORP’s own SEC filings multiplied by the closing price we hold for the same stock.
