Greenstone Partners, as the Exclusive Investment Advisor, is pleased to present the opportunity to acquire the 100% fee-simple interest in 1841 Centre Point Circle (the “Property” / “Investment”), a 34,370-square-foot single-tenant net-leased life sciences laboratory located in Naperville, Illinois. The Property is fully leased to CellCarta Biosciences, a global contract research organization serving pharmaceutical and biotechnology companies backed by Arsenal Capital Partners, a leading New York-based private equity firm focused on building healthcare and industrial growth platforms.

CellCarta recently expanded its footprint to encompass the entire premises, increasing its physical commitment to the Property and further strengthening one of its two U.S. laboratory locations. With 15 years of remaining lease term and 3% annual rent increases, the Investment provides durable, growing cash flow backed by a specialized life sciences user. Over $2.6 million has recently been invested into the Property to accommodate the tenant’s highly specialized lab environment. The investment into the space would make a relocation extremely expensive, disruptive and intensive to replicate elsewhere. The tenant sits within the rapidly expanding life sciences sector, which continues to benefit from strong pharmaceutical demand, increased investment in clinical research, and the continued shift toward precision medicine.

Located in Naperville, one of the Midwest’s most desirable and highly ranked suburban communities, the Property benefits from a premier DuPage County location with access to an affluent population base, exceptional amenities, and a deep healthcare ecosystem. Naperville was ranked the #1 Best City to Live in America by Niche in 2026, while DuPage County is Illinois’ second-largest county by population with more than 930,000 residents, providing the Investment with both scale and long-term demand drivers. The immediate area is supported by strong household economics, including a 1-mile average household income of $150,000 and a 1-mile median home value of $497,000, reinforcing the quality and stability of the surrounding market. Ownership also benefits from DuPage County’s comparatively favorable commercial tax environment relative to Cook County, enhancing after-tax economics in one of Chicago’s strongest suburban markets.
