AI Analysis · Q4 2025

Rush Island Management's $1.60B Q4 2025 13F is a dedicated real-estate investment trust portfolio that doubled its AUM from $754M in one quarter and expanded its holding count from 10 to 17 by adding nine new REIT names across every major property category. Essex Property Trust, NNN REIT, UDR, Federal Realty, Realty Income, Americold Realty, Acadia Realty Trust, National Storage Affiliates, and SmartStop Self Storage all entered at meaningful size — collectively representing $715M of new capital deployment. The two positions sold were Lineage Inc (a cold-storage logistics company) and Hut 8 (a crypto miner), both of which had been anomalous in a REIT-only framework. The portfolio'sprior core — SBA Communications, Healthcare REIT, Ventas, Kilroy Realty, and First Industrial — was held or increased, with SBA Communications receiving a $45.4M addition at the largest weight. The remaining holdings span apartments, industrial, net-lease retail, self-storage, healthcare facilities, and tower infrastructure.

At $227.8M and 14.2%, SBA Communications is the portfolio's largest position. It was increased 24.8% in shares and $45.4M in value, confirming Broadwood's conviction in the wireless tower and communications-infrastructure REIT. SBA is the most defensible REIT asset class: tower leases are long-duration, rent escalators are fixed or inflation-linked, and the carrier tenants have little choice but to pay. The addition to SBA during an interest-rate-sensitive quarter signals that Broadwood views tower REITs as a high-cash-flow, low-capital-expenditure shelter from real-estate volatility.
