On May 24, 2017, Quintiles IMS Holdings, Inc. (the “Company”) entered into an underwriting agreement (the “Underwriting Agreement”) with Morgan Stanley & Co. LLC (the “Underwriter”) and certain selling stockholders named therein (the “Selling Stockholders”). Pursuant to the Underwriting Agreement, the Selling Stockholders agreed to sell 10,571,003 shares of the Company’s common stock, $0.01 par value per share (the “Common Stock”), to the Underwriter at a price of $84.01 per share. Also pursuant to the Underwriting Agreement, the Company purchased from the Underwriter 3,571,003 shares of the Common Stock that were sold by certain Selling Stockholders in the offering, at a per-share purchase price equal to the per-share purchase price paid by the Underwriter to the Selling Stockholders, resulting in an aggregate purchase price of approximately $300 million (the “Repurchase”). The Repurchase was funded with cash on hand and borrowings from the Company’s revolving credit facility.

The Underwriting Agreement contains customary representations, warranties, and covenants of the Company and also provides for customary indemnification by each of the Company, the Selling Stockholders, and the Underwriter against certain liabilities and customary contribution provisions in respect of those liabilities.

The sale of the Common Stock by the Selling Stockholders was made pursuant to the Company’s Registration Statement on Form S-3 (Registration No. 333-218209), including a final prospectus supplement dated May 24, 2017 to the prospectus contained therein dated May 24, 2017, filed by the Company with the Securities and Exchange Commission pursuant to Rule 424(b)(7) under the Securities Act of 1933, as amended. The sale of the Common Stock closed on May 31, 2017.

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