BlackRock (BLK) Q3 2026 Earnings: Adjusted Margin Rises to 47.8%

BlackRock (BLK) reported third-quarter 2026 earnings for the period ended September 30, 2026, in an 8-K earnings release and on its earnings call on October 14, 2026, and both its adjusted operating margin and the quality of its client inflows came in above the prior baseline [1][2]. Coming into the quarter, four questions mattered: whether the adjusted operating margin could move beyond 45.9%, whether inflows could hold the fee rate, whether private markets could turn fundraising into fee revenue, and whether technology subscriptions could sustain low- to mid-teens growth. The first two were confirmed this quarter, while private markets and technology were mixed. Taken together, growth and margin expansion came mainly from public-market scale, rising markets and inflows into higher-fee ETFs, while private-markets expansion remains at the fundraising and deployment stage.

BlackRock is an asset manager with $15.5 trillion of client assets at the end of the third quarter [1]. It runs iShares ETFs, private-markets investing and the Aladdin investment technology platform, and it earns most of its revenue as base fees charged on client assets; in 2025, base fees and securities lending revenue made up about 79% of total revenue [3]. Management's 2030 goal is for private markets and technology together to contribute more than 30% of revenue [2].

Adjusted operating margin rose to 47.8%

BlackRock's adjusted operating margin moved past the 47% high it reached in 2021, and it also expanded after excluding performance fees. The adjusted operating margin was 47.8% in the third quarter, compared with 44.6% a year earlier and 45.9% in the second quarter [1]. Excluding performance fees and related compensation, the margin was 48.6%, up 230 basis points year over year [2].

The margin expanded because revenue grew faster than expenses. Revenue used for the margin calculation rose about 18.7% year over year, while adjusted expense rose 14%, including 12% growth in compensation and 6% growth in G&A [1][2]. Management reiterated its outlook for a mid-single-digit increase in full-year G&A [2]. Performance fees rose $114 million year over year, largely from a single hedge fund whose annual performance period ends in the third quarter, so the margin including performance fees is elevated [1].

Part of the earnings-per-share growth is less repeatable. Adjusted diluted EPS was $15.93, up 38% year over year and faster than the 27% growth in adjusted operating income [1]. The gap came mainly from $164 million of nonoperating investment gains, most of them noncash marks on BlackRock's minority stakes in Securitize and Circle [2]. The GAAP operating margin was 30.0%, held down by a $564 million change in the fair value of contingent consideration that is tied to BlackRock's share price [1]. BlackRock repurchased $550 million of shares in the third quarter, and management anticipates repurchasing at least $550 million in the fourth quarter [2].

Organic base fee growth accelerated to 11%

The quality of client inflows held BlackRock's fee rate. Net inflows were $205 billion in the third quarter, and annualized organic base fee growth was 11%, compared with 8% in the second quarter [1][2]. This measure strips out market movements and captures only the base fee growth from new client money; it has now been at or above 8% for five consecutive quarters [2].

Inflows concentrated in products priced above the firm's average fee. ETFs took in $135 billion, including $41 billion into precision ETFs and $22 billion into active ETFs, while institutional index products had $27 billion of net outflows concentrated in low-fee index equities [2]. On an equivalent day count basis, the annualized effective fee rate was approximately flat compared with the second quarter [2]. Base fees and securities lending revenue were $6.036 billion, up 19.6% year over year and broadly in line with the roughly 19% rise in average AUM [1]. Revenue growth therefore came mainly from a larger asset base, and the fee rate did not rise meaningfully year over year.

Private markets and technology: capital is growing faster than revenue

BlackRock's private-markets capital is growing, but fee revenue has not kept pace. Private markets had $15.3 billion of net inflows in the third quarter, $68 billion of gross fundraising over the last twelve months and $96 billion of AUM not yet earning fees [1][4]. With HPS now a full year inside the comparison base, private-markets base fees were $668 million, up only 2.3% year over year, and private-markets performance fees fell 36% [1]. Management did not update cumulative progress toward its $400 billion fundraising target this quarter [2]. Technology services and subscription revenue grew 14% year over year, but annual contract value, the leading indicator for that revenue, slowed from 15% growth in the second quarter to 12% [1][2].

Conclusion

The third quarter strengthened the case for BlackRock's growth and profit conversion, and shareholder returns proceeded as guided. Operating leverage has shown up in the recurring fee business, but this round of expansion was driven mainly by public markets, which does not match the path of raising the revenue share of private markets and technology. The 11% growth rate benefited from strong markets and elevated client activity, and management treats 6% to 8% as the sustainable range [2]. The next tests are whether the margin excluding performance fees keeps expanding year over year after performance fees fall back, whether the $96 billion of assets not yet earning fees starts generating fees within one or two quarters, and whether annual contract value growth returns to 13% or higher.
