In short

Across the third quarter, individual employee compensation averaged over $322,000, driven largely by $1.1 billion in equity awards. Workforce expenses reached $4.8 billion over the first nine months of 2026, making up just 15% of the firm's $33.2 billion in revenue compared to outpacing sales in 2023.
