SHELTON – The energy-as-a-service provider Budderfly has closed on a $100 million expansion of its corporate debt facility with Nuveen Energy Infrastructure Credit, bringing the total corporate facility to $200 million and a total investment in excess of $300 million by Nuveen EIC including project debt facilities.
This latest investment reflects the continued expansion of Budderfly’s relationship with Nuveen and builds on an initial $100 million corporate debt facility established in May 2025. In total, Budderfly has access to more than $1.1B in capital
“Budderfly has demonstrated strong execution and a differentiated ability to deliver infrastructure modernization at scale,” said Don Dimitrievich, head of Nuveen Energy Infrastructure Credit. “Our increased commitment reflects confidence in the company’s performance, its proven business model, and the significant opportunity to deploy capital into solutions that provide both compelling financial returns and tangible value for customers.”
Since first partnering in 2024, Nuveen has steadily increased its commitment to Budderfly and participates in both corporate and project financing facilities, supporting the company’s rapid growth and platform scaling. This builds on a series of recent financings, including the expansion of Budderfly’s project debt facilities to $550 million.
“Nuveen’s continued investment is a powerful validation of our model and the growing demand for energy infrastructure solutions in the commercial sector,” said Al Subbloie, Budderfly CEO. “With this expanded facility, we are accelerating deployment at a time when businesses are actively seeking ways to reduce costs, improve operational resilience, and modernize their infrastructure.
“Our ability to scale is underpinned by strong financial performance, including achieving positive EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization) in 2025, and this additional capital enables us to build on that momentum.”
Budderfly will use the additional capital to scale its turnkey energy infrastructure model, helping businesses modernize aging facilities, reduce operating costs, and improve energy performance with no upfront investment. Through long-term service agreements, Budderfly invests in and manages comprehensive infrastructure that includes critical systems like HVAC, lighting, refrigeration, controls, and water technologies.
Budderfly’s platform serves a broad range of industries, including restaurants, retail, healthcare, and manufacturing, delivering measurable cost savings and operational improvements to customers while generating predictable, long-term cash flows.
