UPDATE: Bionano Genomics prices $200 million underwritten stock offering at a discount of $6 a share

Bionano Genomics Inc.
BNGO,
+8.42%
priced a $200 million underwritten stock offering announced late Tuesday at a discount of $6 a share, selling 33.3 million shares. The stock closed Tuesday at an alltime high of $9.14. The genome sequencing company’s shares have gained 662% in the last 12 months on little news flow, and trading volumes have been active in recent sessions. Bionano previously sold 29 million shares at $3.05 a share less than two weeks ago. The stock fell 22% in premarket trade to reflect the dilutive effect of the offering. Oppenheimer was sole bookrunner on the deal with BITG acting as lead manager and Ladenburg Thalmann and Maxim Group acting as co-managers. Underwriters have a 30-day option to purchase another 5 million shares at the offering price. Bionano shares traded for less than $1 for much of 2020, before prices shot higher just before the end of the year despite no public announcements about changes at the genome-analysis company, which lost nearly $30 million on sales of $4.5 million in the first nine months of 2020.
