Sunnova Announces Appointment of Robyn Liska as Interim Chief Financial Officer and Provides Financial Strategy Update

Sunnova Energy International Inc. (“Sunnova” or the “Company”), an industry-leading adaptive energy services company, today announced a series of strategic actions to support its ongoing efforts to stabilize the Company’s financial foundation and position the business for long-term success.

To steward the Company into this next chapter, Sunnova appointed Robyn Liska as interim Chief Financial Officer, effective March 31, 2025. In this role, Liska will serve as a core part of Sunnova’s leadership team, advancing the Company’s go-forward financial and operational strategy alongside CEO Paul Mathews. Liska brings a strong track record of strategic financial leadership, capital markets and energy policy expertise, and deep industry insights to Sunnova, with more than 15 years of experience across the energy and renewables sectors.

Previously, Liska served as an Executive Director in J.P. Morgan’s Power and Renewables Investment Banking division, a Director in Bank of America’s Energy and Clean Power Equity Capital Markets group, and an Associate Director in UBS’s Global Power & Renewables group. With proven experience advising high-growth energy companies through periods of transformation, including advising the Company on previous transactions, the Board of Directors believes that Liska’s appointment will enhance Sunnova’s financial agility and strategic planning capabilities. Liska succeeds Eric M. Williams, who stepped down as Executive Vice President and Chief Financial Officer, effective March 30, 2025.

“Robyn has deep industry knowledge and a proven record of driving financial transformation,” said Paul Mathews, Sunnova Chief Executive Officer. “Her expertise will be invaluable as we continue to work to stabilize our foundation, sharpen our execution, and position Sunnova to succeed in today’s evolving solar energy market. I look forward to partnering closely with Robyn to build a stronger, leaner, and more agile Sunnova for the future.”

“This is a defining moment for Sunnova, and I’m honored to help lead the Company through its next chapter,” said Liska. “There is important work to be done, and I’m proud to join a strong leadership team that is moving with clarity and purpose to enhance Sunnova’s financial position and lay a foundation for near-term cash generation and long-term value creation. I look forward to working closely with Paul, the Board, and the Sunnova team to deliver results with discipline, transparency, and purpose.”
