In addition, the Company announced that in the subscription offering that ended on June 15, 2021, the Company received orders in excess of the adjusted maximum of the offering range. Accordingly, 27,772,500 shares of the Company’s common stock are expected to be sold in the offering at a price of $10.00 per share. The Company will also contribute 750,000 shares of common stock and $1.5 million in cash to Blue Foundry Charitable Foundation, Inc.
