Lexicon Announces Pricing of $85.0 Million Public Offering and Concurrent Private Placement

THE WOODLANDS, Texas, July 28, 2022 (GLOBE NEWSWIRE) -- Lexicon Pharmaceuticals, Inc. LXRX ("Lexicon") today announced the pricing of its previously announced underwritten public offering of 16,843,600 shares of its common stock, par value $0.001 (the "Common Stock"). The shares of Common Stock are being offered at a public offering price of $2.50 per share. All of the shares are being offered by Lexicon. The gross proceeds from the public offering are expected to be approximately $42.1 million, before deducting underwriting discounts and commissions and other offering expenses. In addition, Lexicon has granted the underwriters a 30-day option to purchase up to an additional 2,526,540 shares of Common Stock (the "Option Shares") at the public offering price, less underwriting discounts and commissions. The public offering is expected to close on or about August 1, 2022, subject to the satisfaction of customary closing conditions.

Lexicon currently intends to use the net proceeds that it will receive from the public offering and the concurrent private placement, together with its existing cash and cash equivalents and short-term investments, for (i) funding pre-commercial and commercial launch activities for sotagliflozin in heart failure; (ii) funding continued development of sotagliflozin in heart failure and LX9211 in neuropathic pain; and (iii) working capital and other general corporate purposes.

Citigroup and Piper Sandler are acting as joint book-running managers for the public offering.

In addition to the shares being sold in the underwritten public offering, Lexicon has agreed to sell 17,156,400 shares of its Common Stock to raise gross proceeds of approximately $42.9 million in a concurrent private placement at $2.50 per share to one or more affiliates (the "Private Placement Purchasers") of Invus, L.P., Lexicon's largest stockholder. The Private Placement Purchasers will have the option to purchase, on a pro rata basis, up to an additional 2,573,460 shares of Common Stock at the public offering price of $2.50 per share to the extent the underwriters exercise their option to purchase the Option Shares. The sale of these shares of Common Stock will not be registered under the Securities Act of 1933, as amended (the "Securities Act"). The concurrent private placement is also scheduled to close on August 1, 2022, subject to the satisfaction of customary closing conditions. The closing of the underwritten public offering is not conditioned on the closing of the concurrent private placement.
