BOSTON PROPERTIES LTD PARTNERSHIP 8-K

What Happened
Boston Properties Ltd Partnership (filed by BXP, Inc. and the Partnership) announced on March 6, 2026 that it filed a new automatic shelf registration (Form S-3) and related prospectus supplements to commence a new $1.0 billion "at‑the‑market" (ATM) equity offering program. The new $1.0B program replaces a prior $600 million ATM program that was scheduled to expire on May 17, 2026. The registration also covers (i) up to 152,905 shares issuable if previously issued Partnership common units are redeemed and (ii) resale by certain selling stockholders of up to 13,252,000 shares issuable upon exchange of the Partnership’s 2.00% Exchangeable Senior Notes due 2030.

Key Details

• Filing date: March 6, 2026; new Form S-3 replaces prior shelf expiring May 17, 2026.
• Offering size and term: up to $1.0 billion of common stock may be sold over a period of up to three years; Company has no obligation to sell any shares.
• Sales mechanics: offering can be conducted as "at‑the‑market" sales, negotiated trades or block trades under a Sales Agreement with multiple sales agents and may include forward sale transactions (Master Forward Confirmations) that can be settled in shares or cash.
• Fees: Sales agents’ compensation will not exceed 2.0% of gross proceeds; forward sellers’ commission (reflected as a reduced forward price) will not exceed 2.0% (subject to agreement terms).

Why It Matters
This filing gives Boston Properties flexible, near‑term authority to raise equity capital (up to $1.0B) if management chooses to do so. For investors, that means potential future dilution if shares are sold under the ATM program or via forward transactions, but also increased financial flexibility for the company’s capital needs. The company is not required to sell any shares; actual issuance will depend on market conditions, stock price, capital needs and management decisions.
