• DigitalBridge will acquire ArcLight Capital Partners for up to $1.05 billion, combining two specialist infrastructure platforms with assets representing more than $150 billion.
• ArcLight brings major power infrastructure exposure, including more than 70 GW of generation assets and 48,000 miles of electric and gas transmission and storage infrastructure.
• The deal reflects rising investor focus on AI’s power needs, as data centers, electrification and reshoring place new pressure on energy systems.

DigitalBridge Moves Deeper Into Power Infrastructure

DigitalBridge Group will acquire ArcLight Capital Partners in a deal worth up to $1.05 billion. The agreement creates a larger alternative asset management platform focused on power, AI and digital infrastructure.

Under the terms, DigitalBridge will pay a base purchase price of $650 million. A further $400 million may be paid through contingent consideration.

DigitalBridge is a global digital infrastructure investment manager. ArcLight is one of North America’s leading specialist investors in power and electric infrastructure. Combined, the two platforms represent more than $150 billion in assets.

For investors, the deal points to a deeper shift in infrastructure markets. Compute growth, data center expansion, electrification and reshoring are lifting demand for reliable power. Grid capacity, capital markets and permitting systems are now under greater strain.

Completion depends on the previously announced acquisition of DigitalBridge by an affiliate of SoftBank Group. The ArcLight transaction will not change the terms or consideration payable under the SoftBank acquisition.

ArcLight Brings Large-Scale Power Expertise

Founded in 2001, ArcLight has built one of North America’s largest private power generation portfolios and development pipelines.

Since inception, the firm has owned, controlled or operated more than 70 GW of generation assets. Its platform has also managed 48,000 miles of electric and gas transmission and storage infrastructure. Those assets represent more than $90 billion of enterprise value.

Across its business, ArcLight combines strategy, technical development, operations and commercial execution. The company also has an 85-person power development organization with a pipeline of more than 15 GW.

That capability adds a critical layer to DigitalBridge’s digital infrastructure platform. Data centers and hyperscale networks no longer depend only on capital, land and connectivity. Reliable energy, delivered at scale and with regulatory credibility, is becoming just as important.

“Digital infrastructure is a specialist business, and ArcLight has operated with that same philosophy in power infrastructure for more than two decades, building deep expertise across power, renewables, batteries, transmission, and midstream infrastructure,” said Marc Ganzi, Chief Executive Officer of DigitalBridge. “AI is rewiring the global power equation, accelerating investment across generation, transmission, and behind-the-meter infrastructure.”

AI Growth Is Changing Infrastructure Finance

AI demand is reshaping capital allocation across data centers, power generation, transmission, storage and behind-the-meter infrastructure.

SoftBank Group’s wider position in technology and AI adds another layer to the deal’s strategic logic. Once SoftBank’s acquisition of DigitalBridge is completed, ArcLight will operate as a distinct business within the DigitalBridge platform.

New investment solutions are expected to support power and digital infrastructure development across North America and global markets. Priority areas could include compute infrastructure, grid-linked generation, batteries, transmission assets and energy systems for large-load customers.

“I founded ArcLight in 2001, as one of the first dedicated power infrastructure investment platforms, and more than two decades later we are taking another significant step toward building a platform for the growing convergence of power, AI, and digital infrastructure,” said Mr. Revers, Founder of ArcLight. “As demand for compute, connectivity, and electrification continues to accelerate, we believe the next phase of infrastructure investing will increasingly require integrated expertise across both power and digital infrastructure.”

Power Becomes The Digital Economy’s Bottleneck

For C-suite leaders and infrastructure investors, the message is clear. Digital expansion now depends on power strategy.

AI infrastructure, manufacturing reshoring and electrification are placing new pressure on energy systems. That pressure creates openings for asset managers with development capability, regulatory experience and long-term customer relationships.

“Meeting the power demands of AI infrastructure, reshoring, and electrification is a generational opportunity. Power has become the critical bottleneck for digital infrastructure buildout, and solving it takes expertise and dedicated people,” said Mr. Acconcia, Managing Partner of ArcLight. “We’ve built 25 years of technical knowledge, regulatory relationships, and operational depth in electrification infrastructure.”

ArcLight To Remain Separately Managed

ArcLight will operate as a separately managed business within DigitalBridge. Its investment processes, risk management approach and limited partner commitments will remain in place.

After completion, Daniel Revers will become Vice Chairman of DigitalBridge. Angelo Acconcia will remain Managing Partner of ArcLight and continue leading the firm day to day. Jake Erhard, currently a Partner at ArcLight, will become Senior Partner.

Customary closing conditions still apply. These include regulatory approvals, required limited partner consents and completion of the SoftBank acquisition. DigitalBridge said the merger agreement will be filed with the SEC.

Barclays is acting as financial advisor and sole committed financing provider to DigitalBridge. Morgan Stanley & Co. is serving as financial advisor to ArcLight.

For global infrastructure markets, the deal places power at the center of the AI investment cycle. It also shows how climate, energy security and digital competitiveness are becoming part of the same capital allocation conversation.
