If Shareholder is available

To be short - I’m from Sodali & Co. and I’m calling since you’re a shareholder of an Innovator ETF. As you may already know, Innovator has entered into an agreement to be acquired by Goldman Sachs. Shareholders are being asked to vote their shares to approve a new advisory agreement and an expanded board. Do you have 30 seconds to cast your vote? This will stop all outreach.

If Yes:

The Board of Trustees recommends a vote in FAVOR of the proposals. Would you like to vote along with their recommendation?

IF YES:

If we identify any additional accounts before the meeting, would you like to vote them the same way as today?
