Convertible Note Hedge Transactions

In connection with the public offering of 2.75% Convertible Senior Notes due 2022 (the “Notes”) by Horizon Global Corporation (the “Company”), on January 26, 2017, and in connection with the full exercise of the Notes underwriters’ over-allotment option, on January 27, 2017, the Company entered into convertible note hedge transactions (the “Convertible Note Hedge Transactions”) with respect to its common stock, par value $0.01 per share (the “Common Stock”), with each of JPMorgan Chase Bank, National Association, London Branch, Wells Fargo Bank, National Association and Bank of America, N.A. (collectively, the “Counterparties”), affiliates of three of the underwriters in the Company’s public offering of the Notes and recent public offering of Common Stock. The Company paid an aggregate premium of approximately $29.0 million to the Counterparties for the Convertible Note Hedge Transactions. The Convertible Note Hedge Transactions cover, subject to anti-dilution adjustments substantially similar to those contained in the Notes, approximately 5.0 million shares of Common Stock, the same number of shares initially underlying the Notes. The Convertible Note Hedge Transactions are exercisable upon conversion of the Notes and will expire upon the maturity of the Notes, unless earlier exercised or terminated.

The Convertible Note Hedge Transactions are expected to reduce the potential dilution upon conversion of the Notes and/or offset any cash payments the Company is required to make in excess of the principal amount of converted Notes, as the case may be, in the event that the market price per share of the Common Stock, as measured under the terms of the Convertible Note Hedge Transactions, is greater than the strike price of the Convertible Note Hedge Transactions, which initially corresponds to the conversion price of the Notes. The Convertible Note Hedge Transactions are subject to anti-dilution adjustments substantially similar to those applicable to the conversion rate of the Notes.

Aside from the initial payment of a premium to the Counterparties under the Convertible Note Hedge Transactions, the Company is not required to make any cash payments to the Counterparties under the Convertible Note Hedge Transactions.

The Convertible Note Hedge Transactions are separate transactions, entered into by the Company with the Counterparties, and are not part of the terms of the Notes. Holders of the Notes will not have any rights with respect to the Convertible Note Hedge Transactions.

Warrants

In addition, concurrently with entering into the Convertible Note Hedge Transactions, on January 26, 2017 and January 27, 2017, the Company separately entered into warrant transactions (the “Warrants”), whereby the Company sold to the Counterparties warrants to acquire, collectively, subject to anti-dilution adjustments, approximately 5.0 million shares of Common Stock at an initial strike price of $29.60 per share. The Company received aggregate proceeds of approximately $21.5 million from the sale of the Warrants to the Counterparties. The Warrants were sold in private placements to the Counterparties pursuant to an exemption from the registration requirements of the Securities Act of 1933 afforded by Section 4(a)(2) of such act.

If the market price per share of the Common Stock, as measured under the Warrants, exceeds the strike price of the Warrants, the Warrants could have a dilutive effect with respect to the Common Stock.

The Warrants are subject to either adjustment or termination upon the occurrence of specified extraordinary events affecting the Company, including merger events and, tender offers and the announcement thereof, as well as nationalization, insolvency or delisting involving the Company. In addition, the Warrants are subject to certain specified additional disruption events that may give rise to a termination of the Warrants, including changes in law, insolvency filings and hedging disruptions.

The Company’s initial payment of a premium to the Counterparties under the Convertible Note Hedge Transactions is partially offset by the receipt of a premium under the Warrants. Upon exercise of the Convertible Note Hedge Transactions, the Company may receive a net share settlement (notwithstanding that the Company

settles the Notes in shares of Common Stock), a combination of shares and cash or cash only (where the Company is settling conversions of the Notes in cash only). Settlement upon exercise of the Warrants generally will be in the form of net share settlements, whereby the Counterparties will receive shares of Common Stock with a value equal to the excess of their current market price over the strike price of the Warrants. The Company will not receive any proceeds if the Warrants are exercised.

The Warrants are separate transactions, entered into by the Company with the Counterparties, and are not part of the terms of the Notes or the Convertible Note Hedge Transactions. Holders of the Notes will not have any rights with respect to the Warrants.

The Counterparties and/or certain of their affiliates are lenders under the Company’s asset-based lending facility (the “ABL Facility”) and the Company’s term loan (the “Term B Loan”). Bank of America, N.A. is the agent for the lenders and a lender under the ABL Facility. JPMorgan Chase Bank, N.A. is the administrative agent and lender under the Term B Loan.    

The foregoing description of the Convertible Note Hedge Transactions and the Warrants is qualified in its entirety by reference to the full text of the related agreements, which are filed as Exhibits 10.1 through 10.12 to this Current Report on Form 8-K and are incorporated herein by reference.
