Press Releases of normal companies are crisp and clear, nothing "implied". They also don't hide the price of the transaction, the name of the investor, the amount invested and the conditions for future investment.
"a restricted stock purchase directly from the company at market rate" seems to imply common shares, since there is no market for preferred shares. But it is a valid question that will presumably be answered in the filings in relatively short order.
The company does not sell preferred shares for any price to anyone. How a person can even draw that assumption from reading that press release is anyone's guess.
