KBS Real Estate Investment Trust III, Inc. is a real estate investment trust that focuses on acquiring and managing core office properties throughout the United States. As of December 31, 2025, the company owned 12 office properties and held an equity investment in a Singapore real estate investment trust representing 16.5% of the trust’s outstanding units, which had a fair value of approximately $46.8 million. The company conducts its business through its operating partnership, KBS Limited Partnership III, and depends on its advisor, KBS Capital Advisors, for asset management, disposition, marketing, investor relations and administrative services. KBS Capital Advisors owns 20,857 shares of the company’s common stock. KBS Real Estate Investment Trust III, Inc. has no paid employees and seeks to maximize long term value for its stakeholders through active portfolio management, disciplined capital allocation and a focus on generating stable cash flows from lease contracts.

The company’s primary source of revenue is rental income generated from leasing its office properties to tenants. In addition, it receives regular cash distributions from its equity investment in the Singapore real estate investment trust, which supplement the rental cash flow. Proceeds from occasional property sales or refinancing transactions may also contribute to overall revenue, although the core business model relies on recurring lease payments. The company’s revenue stream is therefore anchored in stable long term lease contracts and periodic distributions from its real estate related investment. Interest income from cash reserves and other incidental sources constitute a minor portion of total revenue.

The company operates through the following segments.

• Real Estate Properties: This segment encompasses the acquisition, leasing, management and disposition of the company's 12 office properties located across the United States, as well as the oversight of its equity investment in the Singapore real estate investment trust. Activities include conducting hold sell analyses, negotiating lease agreements, managing tenant relationships, executing capital improvements and monitoring market conditions for value enhancement. The segment also involves coordinating with the advisor to develop exit strategies for each asset and to satisfy debt related obligations such as loan paydowns and property sales required under loan agreements.

KBS Real Estate Investment Trust III, Inc. operates in a highly competitive U. S. commercial real estate sector where it competes with other REITs, pension funds, insurance companies, investment funds, partnerships and developers for acquisition, disposition and tenant retention. Many of these competitors possess substantially greater financial resources, enabling them to accept higher risk levels and offer more aggressive rental concessions. This competitive environment can exert pressure on the company’s ability to maintain or increase rental rates and to attract or retain tenants in its office properties. In addition, the prevailing high interest rate environment and limited availability of debt financing increase the cost of capital and constrain refinancing options. The company also faces challenges stemming from evolving work from home trends, which have affected demand for office space in certain markets such as the greater San Francisco Bay Area. Despite these headwinds, KBS Real Estate Investment Trust III, Inc. seeks to differentiate itself through a diversified tenant base, active asset management via its advisor and a disciplined approach to capital recycling and value enhancement. The company’s focus on core office properties and its long term investment horizon are intended to provide stability amid market volatility.

The company’s tenant base consists of a diverse mix of office occupants spanning industries such as professional services, technology, finance, healthcare and other sectors. As of December 31, 2025, the top 10 tenants accounted for approximately 30% of total annualized base rent, indicating a balanced exposure across multiple occupants. Lease expirations occur throughout the year, with certain assets experiencing lower demand due to evolving work from home trends and macroeconomic conditions. The company actively monitors tenant industries and strives to maintain a diversified portfolio to reduce reliance on any single tenant or sector. In addition, the firm seeks to retain existing tenants through responsive property management and competitive lease terms while pursuing selective asset sales to optimize portfolio value. Overall, the tenant profile reflects a broad array of corporate users that contribute to the stability of the rental income stream.
