Strategic Advisory for Energy & Infrastructure
Marathon Capital Partners is a leading independent investment bank delivering M&A, capital markets, and strategic advisory services to companies shaping the future of energy, infrastructure, and sustainable technology.
About the Firm
Built for the Complexity of Energy Markets
Marathon Capital Partners provides independent, conflict-free investment banking advisory to energy and infrastructure companies, institutional investors, and project developers. Our senior bankers have spent decades executing complex transactions across conventional and renewable energy, power infrastructure, data centers, and emerging sustainable technologies.
We operate as a dedicated, senior-led team — every engagement is staffed by experienced professionals who understand the technical, regulatory, and financial dimensions of the energy transition. Our independence allows us to deliver advice solely in the interest of our clients, without the competing obligations of a balance sheet or proprietary trading desk.
Headquartered in downtown Chicago, at 120 South Riverside Plaza, Marathon Capital Partners serves as a trusted advisor to developers, sponsors, utilities, and strategic acquirers navigating an evolving energy landscape across North America and globally.
Independence
No proprietary capital, no conflicting interests. Every recommendation serves one constituency — our client.
Sector Depth
Our bankers carry deep domain expertise across energy, infrastructure, and sustainable technology — not generalist coverage repackaged for the sector.
Senior Engagement
Principals lead every transaction from origination through close. We do not delegate to junior-heavy deal teams.
What We Do
Advisory Services
Six integrated advisory capabilities spanning the full capital structure and transaction lifecycle for energy and infrastructure assets.
Mergers & Acquisitions
Sell-side and buy-side M&A advisory for energy companies, infrastructure platforms, and project portfolios. We manage competitive auction processes, negotiate definitive agreements, and structure transactions to optimize value across complex regulatory and tax environments.
Equity Capital Markets
Raise growth and development equity from institutional investors, infrastructure funds, pension capital, and family offices. We structure and place equity for greenfield development, platform buildouts, and growth-stage energy companies.
Debt Capital Markets
Arrange project finance, construction financing, term debt, and tax equity for energy and infrastructure projects. Our team structures financings that align with project cash flows, development timelines, and sponsor return requirements.
Tax Credit Advisory
Structure and monetize federal and state tax incentives — including ITC, PTC, and transferable tax credits under the Inflation Reduction Act — to maximize after-tax project returns and reduce the cost of capital for clean energy investments.
Offtake Advisory
Negotiate and structure power purchase agreements (PPAs), virtual PPAs, hedge structures, and energy supply contracts that underpin asset valuations and project financability.
Energy Transition Advisory
Strategic advisory for companies and investors positioning around the energy transition — including market entry analysis, competitive positioning, decarbonization strategy, and identification of acquisition and partnership targets in emerging technology verticals.
