Question

Aron: S3 filing showed number of shares held by Blackstone as of Feb 27. Could the S3 filing already accounts for the sales completed on March 17?

Excellent question. Let me cross-reference the numbers precisely.

S-3 filing (as of February 27, 2026) — Blackstone holdings by entity:

Entity S-3 Shares (Feb 27) (page 6) Form 4 Shares Sold (Mar 17) Form 4 Remaining S-3 minus Form 4 Sold
ML-1 906,717 181,344 725,373 725,373 ✓
ML-2 12,475,943 2,495,189 9,980,754 9,980,754 ✓
ML-3 2,025,363 405,073 1,620,290 1,620,290 ✓
ML-4 5,404,511 1,080,903 4,323,608 4,323,608 ✓
ML-5 16,394,804 3,278,961 13,115,843 13,115,843 ✓
ML-6 147,871 29,575 118,296 118,296 ✓
ML-7 32,291 6,459 25,832 25,832 ✓
Total 37,387,500 7,477,504 29,909,996 29,909,996

The answer is no — the S-3 does NOT already account for the March 17 sales.

The math is perfectly clean. Every entity's S-3 share count (Feb 27) minus the Form 4 sale (Mar 17) equals the Form 4 post-transaction remaining balance exactly. This means Blackstone held 37,387,500 shares as of February 27, and the 7,477,504 shares were sold after that date.

But here's what's critical: Each entity sold exactly 20% of its holdings. Check:

Every single entity sold exactly 20% pro rata. This is a coordinated, systematic liquidation — not opportunistic selling. The forward contract was structured to dispose of precisely one-fifth of Blackstone's remaining position across all seven fund vehicles simultaneously.

The timeline picture:

  1. Blackstone entered the forward contract (likely weeks/months before March 17)
  2. The financial institution hedged during this period (selling into the market)
