Investment Banking Services

We arrange capital through private placements and underwritings, provide general strategic advisory services for companies and projects, and execute merger, divestiture, acquisition, and corporate development transactions.

We have specialized in the use of tax-exempt and taxable bonds to optimize the debt structure and equity returns of companies, developers, and shareholders seeking non/limited recourse project financing.

Capital Raising-Advisory and Structuring

We raise capital, including equity, mezzanine, subordinated and senior debt, and non/limited recourse financing vehicles for growth and project capital and recapitalizations.

We have closed transactions ranging from basic to highly complex and structured, but in all cases we work to raise the most value added capital for our client’s business strategy.
We maintain a deep and broad set of relationships with potential capital providers, and we are continuously developing new relationships to expand our domestic and international network.
Our relationships include: strategic partners, venture capitalists, private equity firms, family and multi-family offices, hedge funds, and money managers.
We arrange fixed and variable rate bond financing placed with insurance companies, mutual funds, other institutional investors.
We also arrange bank financing from local, regional, and money – center banks including loans, derivative products, and letters of credits.

We also assist companies in the preparation and execution of strategic bankruptcy and/or re-capitalization plans.

Strategic Advisory

We provide independent advice for the development and commercialization of disruptive clean and sustainable technologies.

Mergers and Acquisitions/Corporate Development

We provide advisory services supporting mergers and acquisitions including: strategy development, target identification, valuation, due diligence, and financing.

We assist in the development of corporate strategic plans, identification of strategic alternatives, and potential partners, and execution of agreements for joint ventures, supply, off-take, and other forms of alliances.

With extensive experience in the cleantech and sustainable infrastructure sectors, we have gained an appreciation of what it takes to execute a successful strategic transaction.
