Alterra IOS Secures $400 Million Refinancing From Truist Bank and KeyBank Across 99-Property Portfolio
Alterra IOS has closed a $400 million refinancing with lenders Truist Bank Bank and KeyBank, the Philadelphia-based industrial outdoor storage company announced July 13, 2026. The transaction covers a portfolio of 99 properties across 27 markets, totaling 551 usable acres and nearly 2.1 million square feet of accompanying warehouse space.
Pledge-of-Equity Structure Enables Portfolio-Level Financing
The financing employs a pledge-of-equity structure in place of traditional property-level mortgages, according to the announcement. That approach allows the transaction to operate at the portfolio level rather than requiring individual mortgage instruments on each of the 99 assets, enabling a single financing to span the company's multi-market footprint.
Truist Bank and KeyBank served as joint lenders on the transaction. The deal was announced as a refinancing, suggesting the proceeds retire existing debt on the portfolio rather than fund new acquisitions.
Portfolio Scope: 99 IOS Properties in 27 Markets
The collateral pool underlying the financing consists of 99 industrial outdoor storage properties. The portfolio totals 551 usable acres and is accompanied by nearly 2.1 million square feet of warehouse space, according to the company. The properties are distributed across 27 markets, reflecting a geographically diversified platform.
Industrial outdoor storage properties typically serve uses including truck parking, fleet storage, equipment yards, and contractor yards. The portfolio-level financing structure consolidates exposure under a single credit facility rather than managing individual property loans.
Transaction Context
The refinancing is structured as a pledge of equity rather than a conventional mortgage. No additional financial terms, including interest rate, maturity date, or loan-to-value metrics, were disclosed in the announcement.
The transaction was originated from Philadelphia, Pennsylvania, where Alterra IOS is headquartered. Alterra IOS describes itself as an industrial outdoor storage platform. KeyBank is headquartered in Cleveland, Ohio, and Truist Bank is headquartered in Charlotte, North Carolina.
