Elanco Animal Health Inc. priced shares for its initial public offering above the estimated range late Wednesday. The animal drug company, which is being spun off from Eli Lilly & Co. , priced shares at $24 a piece. Earlier in the month, Elanco had estimated shares in the $20 to $23 range. Under current pricing, Elanco hopes to raise up to $1.74 billion on an offering of 62.9 million shares with an added 9.4 million to underwriters to cover over-allotments. Following the IPO, Lilly expects to keep an 82.3% stake in Elanco, or 80.2% if over-allotment shares are sold.
