Item 1.01. Entry into a Material Definitive Agreement.

On October 2, 2018, Kala Pharmaceuticals, Inc. (the “Company”) entered into an underwriting agreement (the “Underwriting Agreement”) with J.P. Morgan Securities LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated and Jefferies LLC acting as the representatives of the several underwriters named therein (collectively, the “Underwriters”), relating to an underwritten public offering of 7,500,000 shares (the “Underwritten Shares”) of the Company’s common stock, par value $0.001 per share (the “Common Stock”), being sold by the Company. The offering price of the Underwritten Shares to the public is $8.25 per share, and the Underwriters agreed to purchase the Underwritten Shares from the Company pursuant to the Underwriting Agreement at a price of $7.755 per share. After underwriting discounts and commissions and estimated offering expenses, the Company expects to receive net proceeds from the offering of the Underwritten Shares of approximately $57.7 million. Under the terms of the Underwriting Agreement, the Company has granted the Underwriters an option, exercisable for 30 days, to purchase up to an additional 1,125,000 shares of Common Stock (the “Option Shares” and together with the Underwritten Shares, the “Shares”) at the public offering price less the underwriting discounts and commissions.

The Shares will be issued pursuant to a shelf registration statement on Form S-3 that the Company filed with the Securities and Exchange Commission (the “SEC”) on August 20, 2018 (File No. 333-226748) and declared effective by the SEC on August 27, 2018. A prospectus supplement relating to the offering has been filed with the SEC. The closing of the offering is expected to take place on October 5, 2018, subject to customary closing conditions.
