Sustainability & Renewable Resources

Financing sustainable renewable resource projects and infrastructure presents complex challenges. Sperry offers comprehensive advisory services for sustainable infrastructure projects including financial feasibility analysis, credit evaluation of feedstock and off-take agreements and other critical path contracts in preparation for bond issuance, and equity solicitation. Opportunities for public-private partnerships utilizing a broad spectrum of financing tools, including taxable and tax-exempt debt, federal and state grants and loan guarantees, and stakeholder equity are thoroughly reviewed for suitability by our advisory teams.


Sperry principals have experience advising infrastructure projects for:
