Executive TL;DR
BlackRock closed Q3 2026 with $15.5 trillion in AUM, $205 billion of quarterly net inflows and 11% annualized organic base fee growth.
Adjusted EPS of $15.93 rose 38%, with about 75% of the gain from operations and about 24% from a swing in nonoperating income.
Adjusted operating margin of 47.8% already sits above the 45% through-the-cycle goal set for 2030.
Investors in the HPS Corporate Lending Fund requested about 11.5% of shares in Q3 against a 5% quarterly limit, the clearest stress point in the portfolio.
Q4 brings seasonal iShares strength, at least $550 million of buybacks and a Humana joint venture closing.

BlackRock delivered the strongest quarter in its history, and one line of the results hides the most useful detail. Adjusted EPS jumped 38%, but about $1.07 of the $4.38 increase came from a $233 million swing in nonoperating income that included gains on minority stakes in Circle and Securitize.
Remove that swing and operating income still grew 27% on 19% revenue growth, with a 47.8% margin. Few firms managing $15.5 trillion can post those numbers.
Durability deserves the most scrutiny. Private credit redemptions, higher long-term yields and a GAAP income statement bent by acquisition accounting all sit beside the growth story, and this fundamental analysis puts a number on each one.
Let’s begin.

How the Platform Earns Its Fees
Base fees and securities lending revenue reached $6.0 billion in Q3, which is 78% of total revenue. The remaining 22% comes from performance fees ($630 million), technology services and subscriptions ($588 million), distribution fees ($414 million) and advisory and other revenue ($84 million).
iShares ETFs hold $6.36 trillion, or 41% of AUM, and generate 46% of base fee and securities lending revenue. Non-ETF index mandates hold 28% of AUM yet contribute only 6% of those fees.
Private markets show the sharpest gap. They represent 2% of AUM and 11% of base fee and securities lending revenue.

The Acquisition Stack and Leadership
Three deals reshaped the firm in eighteen months. Global Infrastructure Partners (GIP) joined in October 2024, Preqin followed in March 2025 for about £2.5 billion in cash, and HPS closed on July 1, 2025.
The HPS deal added $165 billion of client AUM on day one and carried total consideration of about $12.2 billion net of cash acquired. Part of the price was paid in Subco units, and 7.6 million remain outstanding.
CFO Martin Small told investors that Q3 was the first comparable quarter since the HPS close. That makes the 38% EPS growth rate a cleaner read on the combined platform than any prior quarter.
