The number of shares offered rose significantly, though, from an originally planned total of 7.27 million. The additional 1.7 million shares more than makes up for the lower price. The underwriters have a 30-day over-allotment option of 1.35 million shares. All the shares are being offered by Enphase, not by any individual owners.
