Aerie Pharmaceuticals Upsizes and Prices Private Offering of $275 Million 1.50% Convertible Senior Notes Due 2024

Durham, NC, September 4, 2019 – (BUSINESS WIRE) – Aerie Pharmaceuticals, Inc. (NASDAQ: AERI), an ophthalmic pharmaceutical company focused on the discovery, development and commercialization offirst-in-class therapies for the treatment of patients with open-angle glaucoma, retinal diseases and other diseases of the eye today announced that it has priced $275 million aggregate principal amount of its 1.50% convertible senior notes due 2024 (the “notes”). The offering was increased to $275 million aggregate principal amount of notes from the previously announced offering size of $250 million aggregate principal amount of notes. The notes are being sold in a private offering to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended. Aerie has also granted the initial purchasers of the notes a13-day option to purchase up to an additional $41.25 million aggregate principal amount of the notes. The sale of the notes is expected to close on September 9, 2019, subject to customary closing conditions.

The notes will be senior, unsecured obligations of Aerie, and will bear interest at a rate of 1.50% per annum, payable semi-annually in arrears. The notes will mature on October 1, 2024 unless they are redeemed, repurchased or converted prior to such date. Prior to April 1, 2024, the notes will be convertible at the option of holders only during certain periods and upon satisfaction of certain conditions. On and after April 1, 2024, the notes will be convertible at the option of the holders at any time until the close of business on the second scheduled trading day immediately preceding the maturity date. Upon conversion, the notes may be settled in shares of Aerie common stock, cash or a combination thereof, at Aerie’s election.

Aerie may redeem all or any portion of the notes, at its option, on or after October 3, 2022 (and, in the case of a partial redemption, no later than the 50th scheduled trading day immediately before maturity), at a cash redemption price equal to 100% of the principal amount of the notes to be redeemed, plus any accrued and unpaid interest to, but excluding the redemption date, if the last reported sale price of Aerie common stock has been at least 130% of the conversion price then in effect for a specified period of time ending on the trading day immediately before the date the notice of redemption is sent.

Holders of notes may require Aerie to repurchase their notes upon the occurrence of certain events that constitute a fundamental change under the indenture governing the notes at 100% of their principal amount, plus any accrued and unpaid interest to, but excluding, the date of repurchase. In connection with certain corporate events or if Aerie calls any note for redemption, it will, under certain circumstances, be required to increase the conversion rate for holders who elect to convert their notes in connection with such corporate event or notice of redemption.

The notes will have an initial conversion rate of 40.0400 shares of common stock per $1,000 principal amount of notes, which will be subject to customary anti-dilution adjustments in certain circumstances. This represents an initial conversion price of approximately $24.98 per share, which represents a premium of approximately 35% to the $18.50 last reported share price of Aerie common stock on the Nasdaq Global Market on September 4, 2019.

Aerie estimates that the net proceeds from the offering will be approximately $266.1 million (or approximately $306.3 million if the initial purchasers exercise their option to purchase additional notes in full) after deducting the initial purchasers’ discount and estimated offering expenses payable by Aerie. Aerie intends to use approximately $28.6 million of the net proceeds from the offering of the notes to pay the cost of the capped call transactions described below. If the initial purchasers exercise their option to purchase additional notes, Aerie intends to use a portion of the net proceeds from the sale of the additional notes to pay the cost of entering into additional capped call transactions. Aerie expects to pay approximately $6.5 million in termination fees and expenses in connection with the termination of its existing senior secured credit facility. Aerie expects to use the remainder of the net proceeds from the offering of the notes for general corporate purposes, including to fund its commercialization programs in United States for both Rhopressa^® and Rocklatan^®, its clinical, regulatory and commercialization efforts beyond United States, further development of other potential pipeline opportunities, including activities to support execution of its retina programs, evaluating possible uses of its existing proprietary portfolio of molecules beyond ophthalmology, its external business development efforts and its manufacturing activities, including the operation of its own manufacturing plant in Ireland.

In connection with the pricing of the notes, Aerie has entered into privately negotiated capped call transactions with certain of the initial purchasers of the notes and/or their respective affiliates (the “capped call counterparties”). The capped call transactions are expected generally to reduce potential dilution to Aerie common stock upon conversion of the notes and/or offset the potential cash payments that Aerie could be required to make in excess of the principal amount of any converted notes upon conversion thereof, with such reduction and/or offset subject to a cap based on the cap price. The cap price of the capped call transaction is initially $37.00 per share of Aerie common stock, representing a premium of 100% above the last reported sale price of $18.50 per share of Aerie common stock on September 4, 2019, and is subject to certain adjustments under the terms of the capped call transactions. If the initial purchasers exercise their option to purchase additional notes, Aerie expects to enter into additional capped call transactions with the capped call counterparties that are expected generally to offset potential dilution and/or potential cash payments relating to additional notes issued upon exercise of the option to purchase additional notes.

In connection with establishing their initial hedges of the capped call transactions, the capped call counterparties have advised Aerie that they and/or their respective affiliates expect to enter into various derivative transactions with respect to Aerie common stock and/or purchase Aerie common stock concurrently with, or shortly after, the pricing of the notes. This activity could increase (or reduce the size of any decrease in) the market price of Aerie common stock or the notes at that time.

In addition, the capped call counterparties and/or their respective affiliates may modify their hedge positions by entering into or unwinding various derivatives with respect to Aerie common stock and/or purchasing or selling Aerie common stock, the notes or other of Aerie’s securities or instruments (if any) in secondary market transactions following the pricing of the notes and prior to the maturity of the notes (and are likely to do so during any observation period related to a conversion of a note or following any issuance of a notice of redemption with respect to the notes). This activity could affect the market price of Aerie common stock or the notes, which could affect noteholders’ ability to convert the notes and, to the extent the activity occurs during any observation period related to a conversion of notes, it could affect the amount and value of the consideration that noteholders will receive upon conversion of such notes.

This announcement is neither an offer to sell nor a solicitation of an offer to buy any of these securities (including the shares of Aerie common stock, if any, into which the notes are convertible) and shall not constitute an offer, solicitation or sale in any jurisdiction in which such offer, solicitation or sale is unlawful. Any offers of the notes (and the shares of Aerie common stock, if any, into which the notes are convertible) will be made only to qualified institutional buyers pursuant to Rule 144A promulgated under the Securities Act of 1933, as amended, by means of a private offering memorandum.

The offer and sale of the notes and any shares of Aerie common stock issuable upon conversion of the notes have not been registered under the Securities Act of 1933, as amended, or any state securities laws, and the notes and any such shares may not be offered or sold in the United States absent registration or an applicable exemption from such registration requirements.
