CHICAGO, ILLINOIS, March 9, 2019 — XMS Capital Partners, LLC (“XMS”), a global, independent financial services firm focused on providing M&A, corporate advisory and asset management services, announced that it served as independent financial advisor to Exact Sciences Corporation (NASDAQ: EXAS). Exact Sciences announced that it priced its underwritten public offering of 0.3750% convertible senior notes due 2027 (the “Notes”) and upsized the offering from $600 million to $650 million aggregate principal amount.

The Notes will be senior unsecured obligations of the Company and will bear interest at a rate of 0.3750% per annum. Interest on the Notes will be payable semi-annually in arrears on March 15 and September 15 of each year, beginning September 15, 2019. The Notes will be convertible into cash, shares of the Company’s common stock (and, if applicable, cash in lieu of any fractional share), or a combination thereof, at the Company’s election. The initial conversion rate will be 8.9554 shares of the Company’s common stock per $1,000 principal amount of Notes, which is equivalent to an initial conversion price of approximately $111.6645 per share. The Notes will mature on March 15, 2027, unless earlier converted or repurchased in accordance with their terms prior to such date, and may not be redeemed by the Company prior to maturity. Prior to September 15, 2026, the Notes will be convertible only upon the occurrence of certain events and during certain periods, and thereafter, until the close of business on the second scheduled trading day immediately preceding the maturity date.

The offering is expected to close on March 8, 2019, subject to customary closing conditions. Concurrently with this offering, in separate transactions, the Company expects to enter into agreements with certain holders of its 1.0% Convertible Senior Notes due 2025 (the “2025 Notes”) to exchange an aggregate of approximately $493.4 million of the outstanding principal amount of the 2025 Notes for consideration consisting of (1) an aggregate amount of approximately $493.3 million in cash and (2) an aggregate amount of approximately 2.16 million shares of the Company’s common stock. The terms of such agreements have been or will be individually negotiated and will depend on the market price of the Company’s common stock and the trading price of the 2025 Notes at the time such agreements are entered into. The cash portion of such consideration will be funded from net proceeds from this offering. The Company may also exchange or induce conversions of the 2025 Notes following completion of this offering and may fund such exchanges or conversions with the proceeds of this offering. The Company intends to use the remaining net proceeds of this offering for general corporate and working capital purposes.

XMS served as the independent financial advisor to Exact Sciences in connection with this offering.
