If there was new financing they would have needed to announce it.
If the additional shares were the conversion of PRE PRODUCTION financing they could wait to include it as part of the 10-K.
By the way, if it was conversion of old financing, the timing would be under the control of the note holder and not PCFG management. The conversion terms were previously announced. The numbers match both in the number of share that debt could pay for at the current price, and the maximum shares they would be allowed to buy(just under 5% of the company).
