Argo Infrastructure acquires UGI propane assets in Hawaiʻi to expand energy resiliency and non-utility gas supply

Argo Infrastructure Partners has moved to deepen its energy footprint in the Hawaiian Islands through the acquisition of propane storage and delivery assets from AmeriGas Propane, L.P., a subsidiary of UGI Corporation (NYSE: UGI). The transaction is being executed through Isle Gas, a wholly owned subsidiary of AMF Hawaiʻi Investment Holdings, LLC, a portfolio company managed by the New York-based infrastructure fund Argo Infrastructure Partners.

The transaction covers approximately 750,000 gallons of propane storage spread across multiple locations and a fleet of delivery vehicles. These assets serve residential and commercial customers across four key Hawaiian markets—Oʻahu, Hawaiʻi Island, Maui, and Kauaʻi. The deal is expected to be finalized in the third quarter of 2025.

Both Isle Gas and Hawaiʻi Gas, which currently delivers propane to nearly 34,000 non-utility customers, are controlled by Argo through its infrastructure fund vehicles. Upon completion, Hawaiʻi Gas will provide the operational backbone for Isle Gas, ensuring continuity of service for transitioning customers.

Why is Argo Infrastructure acquiring UGI’s propane distribution assets in Hawaiʻi and what does it include?

The strategic asset purchase from AmeriGas includes non-utility propane infrastructure essential for off-grid energy supply in Hawaiʻi’s geographically fragmented environment. With limited natural gas access across islands, propane remains a key fuel source for residential heating, cooking, and commercial energy applications in remote and semi-urban areas.

This acquisition involves four main elements: 1) the 750,000-gallon propane storage capacity across undisclosed but operational sites, 2) a delivery fleet actively engaged in inter-island service logistics, 3) non-utility customer contracts across four territories, and 4) integration into an existing service ecosystem led by Hawaiʻi Gas.

The move allows Argo Infrastructure Partners to consolidate overlapping propane distribution capabilities under a vertically integrated platform—reducing operational redundancies while scaling asset-backed coverage across the islands.

How does this acquisition support energy reliability and sustainability across the Hawaiian Islands?

Institutional investors and infrastructure-focused analysts suggest this transaction enhances long-term energy resiliency in Hawaiʻi, where power diversification and decentralized fuel access are considered essential due to frequent weather disruptions, high import dependency, and inter-island logistical challenges.

Jason Zibarras, Managing Partner and Founder of Argo Infrastructure Partners, underscored the platform-building nature of the acquisition, stating that the deal supports “a more resilient and energy-efficient future” in Hawaiʻi.

Through this acquisition, Argo can align Isle Gas with the established operational safety, reliability, and resilience frameworks already in place at Hawaiʻi Gas, while expanding service capabilities to reach thousands of legacy AmeriGas customers.

For a state with ambitious renewable energy mandates and evolving energy needs, Argo’s strategic move is viewed as strengthening the intermediary infrastructure that will be necessary during Hawaiʻi’s transitional decades toward net-zero targets.

What are the financial and institutional motivations behind Argo’s continued investment in Hawaiʻi’s propane infrastructure?

As of the second quarter of 2025, Argo Infrastructure Partners manages over USD 6.25 billion in assets and focuses on long-duration infrastructure investments with strong community and service linkages. Key sectors include regulated utilities, renewable energy platforms, and logistics infrastructure.

While financial terms of the acquisition have not been disclosed, infrastructure investors often place premium valuations on energy storage and distribution assets in geographies with high logistics complexity and reliable demand baselines—both present in Hawaiʻi’s off-grid propane market.

According to institutional sentiment indicators, stable non-utility energy demand, a favorable regulatory backdrop for clean energy transition, and the relative scarcity of scalable assets in the Pacific region likely factored into Argo’s decision to deepen its commitment to Hawaiʻi’s gas ecosystem.

Through AMF and its managed vehicles, Argo has built a resilient platform anchored by Hawaiʻi Gas, whose history dates back to 1904. The addition of Isle Gas strengthens this portfolio, positioning Argo as a central energy operator across regulated and non-regulated market segments in the state.

What operational synergies and transition strategies are expected following the acquisition closing?

Following the close of the transaction in Q3 2025, existing AmeriGas customers in Hawaiʻi will transition to Isle Gas service under the operational purview of Hawaiʻi Gas. Alicia Moy, President of AMF and CEO of Hawaiʻi Gas, indicated that the process will be seamless, with a strong emphasis on customer continuity, safety, and service quality.

“We are committed to making this a smooth transition process for AmeriGas customers as they move to Isle Gas, providing them with continued safe, reliable, and excellent service,” Moy stated.

Operational synergies are expected to emerge from centralized logistics, shared technical expertise, and pooled procurement and maintenance functions. Moreover, Argo intends to invest additional capital and deploy specialized infrastructure know-how to modernize and maintain the acquired assets.

With these reinforcements, analysts anticipate that Isle Gas could enhance service reliability, reduce delivery lag times, and better withstand supply chain shocks or natural disasters, particularly in remote service areas like rural Maui or Kauaʻi.

How does this deal align with Hawaiʻi’s climate goals and energy policy framework?

Hawaiʻi has one of the most aggressive climate and renewable energy targets in the United States, aiming for 100% renewable electricity by 2045 under the Hawaiʻi Clean Energy Initiative. While propane is a fossil fuel, its role as a transitional energy source is seen as critical—especially for backup generation, off-grid heating, and industrial processes where electrification timelines remain long.

By reinforcing propane storage and distribution, Argo and AMF are helping stabilize the current energy ecosystem while longer-term electrification and hydrogen-based alternatives continue to mature.

Institutional observers also highlight that the AMF platform’s governance structure is closely aligned with ESG principles. The emphasis on resilience, continuity, and modernization across its infrastructure holdings reflects growing investor demand for impact-focused yet commercially viable energy investments.

As Alicia Moy noted, AMF’s acquisition will enable “continued focus on energy efficiency, resiliency, and sustainability consistent with Hawaiʻi’s climate objectives,” ensuring the deal supports rather than detracts from the state’s broader energy vision.

What is the future outlook for Argo Infrastructure’s energy platform in the Pacific region?

Looking forward, analysts expect Argo Infrastructure Partners to continue expanding its presence in Hawaiʻi and potentially other Pacific geographies where infrastructure gaps align with the firm’s long-horizon, essential-service investment strategy.

Given its success in integrating Hawaiʻi Gas and launching AMF-managed affiliates like Isle Gas, Argo could pursue further acquisitions in renewable storage, microgrid development, or hydrogen transport infrastructure—areas where energy needs and policy incentives are converging.

For institutional investors, the platform represents a model of embedded infrastructure with consistent returns, modest regulatory risk, and clear ESG-aligned operational themes.

As Argo completes this propane-focused asset acquisition, it is solidifying its position as not just a financial investor, but an operationally active energy stakeholder in Hawaiʻi’s evolving utility and non-utility landscape.
