I think the best approach would be to announce a dividend policy where they spend $2.5M on dividends every quarter.
Subject to conditions and developments, they could then either increase the dividend, or add a share buyback program later.
Because the thing is, if the stock rallies to $10 for some reason, then they would want to do share buybacks. More cash dividends don't add value at that stage.
If they present a plan like this, the market will be impressed. But they have to start with the quarterly cash dividends. They can do it now, or soon. We don't even need a $20M package.
Then, review the situation 6 months from now. Either increase dividends, or add share buybacks.
