Noncontrolling interests relate to the interests in BPLP not owned by BXP and interests in consolidated property partnerships not wholly-owned by the Company. As of June 30, 2025, the noncontrolling interests in BPLP consisted of the following:

During the six months ended June 30, 2025, 116,204 OP Units were presented by the holders for redemption (including an aggregate of 13,038 OP Units issued upon conversion of LTIP Units, 2012 OPP Units and MYLTIP Units) and were redeemed by BXP in exchange for an equal number of shares of Common Stock.

At June 30, 2025, BPLP had outstanding the 2023 - 2025 MYLTIP Units. Prior to the end of the respective three-year performance period for each plan, holders of MYLTIP Units are entitled to receive per unit distributions equal to one-tenth (10%) of the regular quarterly distributions payable on an OP Unit, but will not be entitled to receive any special distributions. After the three-year performance period for each plan has ended, (1) the number of MYLTIP Units, both vested and unvested, that MYLTIP award recipients have earned, if any, based on the establishment of a performance pool, will be entitled to receive distributions in an amount per unit equal to distributions, both regular and special, payable on an OP Unit and (2) with respect to the 2023 - 2025 MYLTIP Units, the Company will make a “catch-up” cash payment on the MYLTIP Units that are ultimately earned in an amount equal to the regular and special dividends, if any, declared during the performance period on a number of shares of Common Stock equal to the number of 2023 - 2025 MYLTIP Units that are earned, less the distributions actually paid during the performance period on all of the awarded 2023 - 2025 MYLTIP Units.

On January 31, 2025, the three-year measurement period for the Company’s 2022 MYLTIP awards ended and, based on BXP’s absolute and relative TSR performance, the final payout was determined to be 59% of target, or an aggregate of approximately $5.4 million (after giving effect to employee separations). As a result, an aggregate of 177,919 2022 MYLTIP Units that had been previously granted were automatically forfeited.


Record Date	Payment Date	Distributions per OP Unit and LTIP Unit	Distributions per MYLTIP Unit
June 30, 2025	July 31, 2025	$0.98	$0.098
March 31, 2025	April 30, 2025	$0.98	$0.098
December 31, 2024	January 30, 2025	$0.98	$0.098

June 28, 2024	July 31, 2024	$0.98	$0.098
March 28, 2024	April 30, 2024	$0.98	$0.098
December 29, 2023	January 30, 2024	$0.98	$0.098

A holder of an OP Unit may present the OP Unit to BPLP for redemption at any time (subject to covenants agreed upon at the time of issuance of OP Units to particular holders that may restrict such redemption right for a period of time, generally one year from issuance). Upon presentation of an OP Unit for redemption, BPLP must redeem the OP Unit for cash equal to the then value of a share of Common Stock of BXP. BXP may, in its sole discretion, elect to assume and satisfy the redemption obligation by paying either cash or issuing one share of Common Stock. Based on the last reported price of a share of Common Stock on the New York Stock Exchange of $67.47 per share on June 30, 2025, the value of the OP Units (other than OP Units owned by BXP), and LTIP Units (including the 2012 OPP Units and 2013 - 2022 MYLTIP Units), assuming in each case that all conditions had been met for the conversion thereof, had all of such units been redeemed at June 30, 2025 was approximately $1.3 billion.

The noncontrolling interests in property partnerships consist of the outside equity interests in ventures that are consolidated with the financial results of the Company because the Company exercises control over the entities that own the properties. The equity interests in these ventures that are not owned by the Company, totaling approximately $2.0 billion and $1.9 billion at June 30, 2025 and December 31, 2024, respectively, are included in Noncontrolling Interests—Property Partnerships on the accompanying Consolidated Balance Sheets (See Note 14).
