Unisys Corporation Announces Pricing of $190 Million Private Offering of Convertible Senior Notes

BLUE BELL, Pa., March 9, 2016 – Unisys Corporation (NYSE: UIS) (“Unisys”) announced today the pricing of $190 million aggregate principal amount of Convertible Senior Notes due 2021 (the “notes”) through a private offering to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended. Unisys granted the initial purchasers an option to purchase up to an additional $28.5 million in aggregate principal amount of the notes on the same terms and conditions, solely to cover over-allotments, if any. The offering size was increased to $190 million from the previously announced amount of $150 million, and the option granted to the initial purchasers was increased to $28.5 million from the previously announced amount of $22.5 million. The sale of the notes is expected to close on March 15, 2016, subject to customary closing conditions.

The notes will be Unisys’ senior unsecured obligations. The notes will bear interest at a rate of 5.50% per year until maturity, payable semiannually in arrears on March 1 and September 1 of each year, beginning on September 1, 2016. The conversion rate will initially be 102.4249 shares of Unisys common stock per $1,000 principal amount of notes (equivalent to an initial conversion price of approximately $9.76 per share of common stock), which represents an approximately 22.5% conversion premium over the last reported sale price of $7.97 per share of Unisys’ common stock on The New York Stock Exchange on March 9, 2016. Upon any conversion, Unisys will settle its conversion obligation in cash, shares of its common stock, or a combination of cash and shares of its common stock, at its election.

Unisys intends to use the net proceeds from the offering of the notes: (i) for general corporate purposes, which may include funding cost reduction and savings initiatives, obligations under its defined benefit pension plans, investments in next-generation services and technologies and repaying existing debt and (ii) to pay the cost of the capped call transactions described below.

In connection with the pricing of the notes, Unisys intends to enter into privately negotiated capped call transactions with the initial purchasers and/or affiliates of the initial purchasers (the “hedge counterparties”). The capped call transactions will cover, subject to customary anti-dilution adjustments, the number of shares of Unisys’ common stock that will initially underlie the notes. The capped call transactions are expected to reduce potential dilution to Unisys’ common stock and/or offset potential cash payments Unisys is required to make in excess of the principal amount upon any conversion of notes. If the initial purchasers exercise their option to purchase additional notes, Unisys may enter into additional capped call transactions with the hedge counterparties.

In connection with establishing their initial hedges of the capped call transactions, Unisys expects that the hedge counterparties and/or their affiliates will enter into various derivative transactions with respect to Unisys’ common stock and/or purchase shares of Unisys’ common stock or other Unisys securities in secondary market transactions concurrently with or shortly after the pricing of the notes, including with certain investors in the notes. These activities could have the effect of increasing, or reducing the size of any decline in, the market price of Unisys’ common stock or the notes at that time.

In addition, Unisys has been advised by the hedge counterparties that the hedge counterparties and/or their affiliates may modify their hedge positions by entering into or unwinding various derivative transactions with respect to Unisys’ common stock and/or by purchasing or selling Unisys’ common stock or other Unisys securities in secondary market transactions prior to the maturity of the notes (and are likely to do so during any observation period related to a conversion of notes).

The notes and Unisys common stock issuable upon the conversion of the notes, if any, have not been registered under the Securities Act of 1933, as amended, or the securities laws of any other jurisdiction and may not be offered or sold absent registration or an applicable exemption from registration requirements.

This news release is neither an offer to sell nor a solicitation of an offer to buy any of these securities nor shall there be any sale of these securities in any state or jurisdiction in which such an offer, solicitation or sale would be unlawful prior to the registration or qualification under the securities laws of any such state or jurisdiction.
