19 July 2019capital raising announcement▼ BadMajor

Raised $2.25 million selling 8,653,846 shares at $0.26 through H.C. Wainwright, with matching Series A warrants at $0.35. The same investors' May 2016 warrants, which still had until November 2021 to run at $0.75, were swapped one-for-one for 4.5 million new warrants at $0.35 - a repricing rather than a rescue of expiring paper, and further dilution on top of the placement.

What it means for a shareholder

8.7m new shares at US$0.260 to raise about US$2.3m. That's 8.1% dilution: every existing holder's slice gets 8.1% smaller. If you held US$1,000 of shares (3,846 at the issue price), your slice goes from 0.00392% to 0.0036% of the company. To keep it you'd need 339 more shares - about US$88 at the issue price.
