Alterra Lands $400M IOS Portfolio Refi

Alterra IOS has received $400 million in refinancing for a 99-property industrial outdoor storage portfolio. Truist Financial Corp. and KeyBank provided the financing.

The portfolio spans 551 usable acres and approximately 2.1 million square feet across 27 states, including California, Florida, Georgia, North Carolina and Texas.

Truist provided $225 million of the financing, while KeyBank contributed the remaining $175 million. The refinancing was structured using an equity pledge framework rather than traditional asset-level mortgages.

“This demonstrates the continued institutionalization of the IOS sector,” Scott Whittle, chief financial officer at Alterra IOS, told Commercial Property Executive. “As the IOS market has grown and matured, lenders have become increasingly comfortable underwriting diversified IOS portfolios and providing scalable financing solutions.”

He explained that the equity pledge structure reduced legal and administrative complexity while preserving flexibility for acquisitions and dispositions. Whittle added that the company expects the structure to remain an important financing tool as its platform continues to grow.

Two properties included in the portfolio are 1125 South Legacy View St. in Salt Lake City and 8800 NE Parvin Road in Kansas City, Mo, Whittle said.

This is not the first time Truist has provided financing to Alterra. Last year, the bank partnered with Bank of Montreal on a $343.6 million refinancing secured by 64 IOS properties across 22 states.

The new refinancing brings Alterra’s total debt commitments across its IOS platform to more than $2 billion, including financing for Alterra IOS Venture II and Venture III. Whittle said the refinancing also provides additional flexibility to support Alterra’s acquisition strategy over the next two years. As of the second quarter of 2026, Alterra owns more than 495 properties across 39 states.

Large capital flows to Alterra IOS

The latest refinancing continues Alterra’s strategy of securing institutional capital to support its expanding IOS platform. In March, PGIM provided Alterra with $103 million for the acquisition of a 23-asset portfolio across 18 markets. It was the first time PGIM provided financing to the company.

Last October, Blue Owl also partnered with Alterra for its first investment in the industrial outdoor storage sector with a $150 million loan for Venture III, which totaled $925 million in equity commitments.

Most recently, Blackstone Real Estate Debt Strategies issued a $244 million note for the acquisition of 37 properties across 165 usable acres and 806,000 square feet. The company also utilized an equity pledge framework for that structure.
