Interactive Brokers Group is on one of our US lists: S&P 500 companies.

Interactive Brokers Group, Inc. earned $314 M of net profit in the Sep 2026 quarter, +19.4% on the same quarter a year earlier. That is the 12th quarter in a row of profit growth. Full-year FY25 profit was $984 M. Over 4 years profit has grown 33.7% a year on average. That is 16.8% of the quarter's revenue.

Net profit is what is left after every cost, interest and tax. Earnings per share, dividends and book value all grow from it.

The same quarter a year earlier earned $263 M.

For the full year, FY25 profit was $984 M (+30.3% on the year before).

Why profit moved: revenue changed +13.5% on a year earlier and the margin moved +0.9 percentage points. Sales did the work, and the margin was about flat.

On average over the last four quarters, profit changed +28.8% and revenue +17.9%. Profit is growing faster than sales: fixed costs are spread over more sales, so each extra dollar of revenue adds more to profit.

Interactive Brokers Group, Inc. reported $1.9 B of income in the Sep 2026 quarter, +13.5% on the same quarter a year earlier. That is the 12th quarter in a row with growth on the year before. Over 4 years it has grown 22.6% a year on average. The last full year, FY25, came in at $6.2 B.

For a bank, revenue is everything it earns: interest on its loans plus fees from its businesses.

The last four reported quarters add to $7.0 B.

FY25 revenue was $6.2 B, +19.4% on the year before.

Recent pace: the last four quarters grew +17.9% on average, against 22.6% a year over the longer run, so this year is growing slower than its own long-run rate.

Is growth speeding up? Revenue over the last 12 months grew +17.9%, against +19.1% a year over the last 8 quarters (stabilising); profit over the last 12 months grew +28.4%, against +29.9% a year (stabilising).

Interactive Brokers Group, Inc.'s net margin was 16.8% in the Sep 2026 quarter, 0.9 percentage points higher than the same quarter a year ago. Its latest full-year margin is the highest it has ever reported. Across 5 years it has been between 11.2% and 15.8%. The latest quarter is above every full year in that period.

Net margin is what the bank keeps from every $100 of revenue after every cost, provision for bad loans and tax. With big fee businesses in the mix, it is the clearest margin we can read for this bank.

Across 5 years it has been between 11.2% and 15.8%, and FY25's 15.8% is the highest of them.

Why: the net margin move is clear, but the cost details behind it are not in our data, so we show the move without guessing the reason.

When margins are at a record, every ratio built on profit looks better than usual, so watch whether they hold.

Interactive Brokers Group, Inc. does not report loan-quality figures this page can read, so this section says so rather than guess. No bad-loan figures are filed in a form this page can read, and none are guessed from the profit line. The income, margin and return sections carry what this business does report.

Gross NPA is the share of the loan book where repayments have stopped. Net NPA is what is left after the money the lender has already set aside for those loans. Falling is good; rising is a warning.

Why: loan quality drives a lender, but its details (new bad loans, recoveries, money set aside) are not in our data for this company. The sections around this one carry what we can back up.

Interactive Brokers Group, Inc.'s revenue was $6.2 B in FY25, +19.4% on the year before, so the loan book is growing. The latest quarter was +13.5% on a year earlier. The net margin on that income is 16.8%, +0.9 percentage points on a year ago.

We read the loan book through revenue: when the book and the businesses grow, revenue grows with them. It is only a rough guide, because interest-rate changes and fee swings can move it a few points in any year.

Interest income stands in for the size of the loan book; changes in interest rates can move it a few points in any year.

In short: a lender grows well when its loan book grows, its margin stays steady and its loans stay clean. Quarterly loan-quality figures are missing here, so revenue growth and margin are the two we watch.

Interactive Brokers Group, Inc.'s P/BV is 5.7×, near the high end of its own history: higher than 79% of past readings. Its usual P/BV (the middle reading) is 3.2×, over 5.3 years of weekly prices. This compares the share price with the company’s own past. It does not say what the business is worth.

For a bank or lender we compare the price with book value, the net worth on its balance sheet. P/BV is how many dollars the market pays for each $1 of that net worth. Below 1× means the market values it at less than its net worth.

Why the multiple is where it is: over the past year book value grew while the price moved +10.4%. The price ran ahead of book value, which pushed the multiple up within its own range.

Where the price move came from: over 5 years the price moved +33.4% a year; about +18.0% a year came from book-value growth and about +15.4 percentage points from the multiple (the market paying more). The split is approximate (price return minus book-value growth). It shows how much of the move came from the market paying a different multiple.

In short: the multiple is high against its own past, so the book value trend underneath matters more than the multiple.

Interactive Brokers Group, Inc.'s business is giving mixed signals. Growth has been steadily positive, but ROE at 5.1% is below the 12% level needed to call it steady growth. This is based on 12 quarters of 4 measures.

Every business is somewhere on a path of getting better or worse, and this section names where. The last 12 quarters of growth in revenue, profit and earnings per share, plus the return the business earns on its capital, are read as lines. Getting worse: the lines are falling. Turning around: a low point has just formed and the last few quarters are rising from it. Getting better: the rise from the low has lasted. Growing steadily: steady growth with healthy returns. Slowing from a peak: still high, but slowing. When the lines disagree the result is mixed; too little history means no reading. CAGR (compound annual growth rate) is the steady yearly rate that would turn the starting value into the latest one. It is the fairest way to compare growth over different periods. If the 1-year figure is much bigger than the 10-year one, recent growth is running faster than the long-run trend. A dash means there is no figure for that period, or the starting year was a loss, where a growth rate means nothing.

Why it matters: when the lines disagree, each line above matters more than any single label.

Compound annual growth rate (%)

Compound annual growth rate over each period, %. Revenue, profit and EPS come from yearly figures; the stock price row is price growth over the same periods. A dash means no figure for that period, or the starting year was a loss.

Interactive Brokers Group, Inc. earned a return on equity of 5% in FY25. Its lowest yearly reading on file was 3% in FY21. On its assets, every $100 earned about $2.28, before the effect of borrowing. For a lender the balance sheet is the business, so the return on equity and on assets have to be read together.

Two numbers rate a bank: ROE, what it earns on shareholders’ money, and ROA, what it earns on all its assets. An ROE above about 13 to 15% is healthy; below that, net worth grows slowly.

That return is below the level a bank needs to grow its net worth quickly, which helps explain why its multiple is where it is.
