I think it is a bullish sign.

1) I am a holder of RVX.WT and RVX.WT.A

I have the chance during a month to exercice these warrants at 1.33 instead of 2.05 or 4.60 respectively.

If the stock price is lower than 1.33 why would I do that? I could buy the shares on the market and keep my warrants.

2) It is during a small window. Decice now or never. So no prolonged option.

3) Its after the last embargo and the new webcast

4) It doesnt change the number of the fully diluted share count which as an impact on a potential buyout price per share.
