On February 4, 2016, Quotient Ltd. (the “Company” or “we”, “us” and “our”) entered into an underwriting agreement (the “Underwriting Agreement”) with J.P. Morgan Securities LLC (the “Underwriter”) in connection with the public offering, issuance and sale by us of 4,444,445 of our ordinary shares of no par value per share, at the public offering price of $9.00, less the underwriting discount, pursuant to an effective registration statement on Form S-3 (File No. 333-206026) and a related prospectus supplement (the “Prospectus Supplement”) filed with the Securities and Exchange Commission. Under the terms of the Underwriting Agreement, we have granted the Underwriter an option, exercisable for 30 days from the date of the Prospectus Supplement, to purchase up to 666,666 additional ordinary shares from us at the public offering price, less the underwriting discount.

We expect to receive net proceeds from the offering of approximately $36.9 million, or approximately $42.5 million if the Underwriter exercises its option to purchase additional shares in full, after deducting the underwriting discount and estimated offering expenses payable by us.

The offering is expected to close on or about February 10, 2016, subject to the satisfaction of customary closing conditions. The Underwriting Agreement contains customary representations, warranties and agreements by the Company, conditions to closing, indemnification obligations of the Company and the Underwriter, including for liabilities under the Securities Act of 1933, as amended, and termination provisions.

The above description of the Underwriting Agreement is qualified in its entirety by reference to the Underwriting Agreement, a copy of which is filed as Exhibit 1.1 hereto and is incorporated herein by reference.

Set forth below is a list of Exhibits included as part of this Current Report.
