Ann: DroneShield completes $2.55 million placement, page-18

What would they be 'buying' though?

Droneshield have minimal sales, customer base, intellectual property, or assets, and are running at a loss of approx $5 million a year.

It's possible someone might try to buy or merge with Droneshield of course, if for no other reason than to simply say they're in the anti-UAS sector, but that would be after the stock crashes in 6 months, when continued lack of sales forces DRO to do another CR to pay for operating costs (just like they are now, again), and SP drops low enough to make it a sensible buy.
