Greenbacker Taps Former Co-CEO David Sher for Strategic Consultant Role

David Sher will continue supporting fundraising and investment efforts through mid-2027 under the new agreement.

Consulting role begins as executive tenure ends

Greenbacker Renewable Energy is entering its next phase with a familiar name still in the mix. David Sher, who steps down as Co-CEO on December 31, 2025, has signed on as a consultant. His focus: helping the firm raise capital and source new investment opportunities.

The agreement kicks in right after his departure and runs through July 1, 2027. It’s built around performance. Sher will support Greenbacker’s fundraising and origination efforts and, in return, may receive up to 5% of net revenue from each stream—funds raised or approved deals originated. Total compensation is capped at $2 million.

Rather than a one-size-fits-all structure, individual engagement letters will define how and when Sher gets paid. That gives Greenbacker the flexibility to align incentives with specific outcomes, and gives Sher a clear path to contribute meaningfully over the next 18 months.

Flexible structure with potential for extension

If needed, the agreement can be ended early under certain conditions. There’s also room for an extension if both sides agree. The company plans to include the full Consultant Agreement in its next Form 10-K.

This move keeps momentum going. Sher’s knowledge of Greenbacker’s investor base and pipeline positions him to step in quickly and provide targeted support. As the company continues to expand its footprint in clean energy and sustainable infrastructure, having a former senior leader engaged in a defined role may help accelerate key initiatives without missing a beat.
