KOOP BRYAN J 4

What Happened

• Bryan J. Koop, Executive Vice President of BXP, received a grant of 13,143 LTIP units (derivative award) on January 30, 2026. The reported per‑unit acquisition price is $0.25, for a total reported value of $3,286.
• This was an award (code A) of limited partnership units, not an open‑market purchase or sale of common stock.

Key Details

• Transaction date: 2026-01-30; Filing date (Form 4): 2026-02-02 (timely filing).
• Instrument: LTIP Units (limited partnership units issued under Boston Properties’ equity incentive program); reported acquisition price $0.25 per unit; total reported value $3,286.
• Shares/units owned after transaction: not specified in the filing.
• Footnote highlights:
  • F1: LTIP Units are units of limited partnership interest in Boston Properties Limited Partnership (BPLP). They can, under certain tax/accounting conditions, be converted into Common OP Units, which in turn may be redeemed for cash equal to the fair market value of a BXP share or exchanged (at the issuer’s election) for one share of common stock. LTIP Units have no expiration date.
  • F2: The 13,143 LTIP Units vest in four equal annual installments beginning January 15, 2027.

Context

• This is a grant of long‑term incentive units rather than an immediate equity purchase or sale. Such awards are standard executive compensation and vest over time; they do not represent immediately tradable common stock until conversion/redemption occurs.
• Because the award vests over four years, any future sale or conversion would be disclosed in later filings. The award itself is factual compensation disclosure and should not be interpreted as a near‑term trading signal.
