Esperion Announces Private Offering of $200.0 Million of Convertible Senior Subordinated Notes

Esperion Announces Private Offering of $200.0 Million of

Convertible Senior Subordinated Notes

ANN ARBOR, Mich., November 10, 2020 (GLOBE NEWSWIRE) --

Esperion (NASDAQ: ESPR) today announced its intention to offer, subject to market conditions and other factors, $200.0 million

aggregate principal amount of Convertible Senior Subordinated Notes due 2025 (the "notes") in a private offering (the

"offering") to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended

(the "Securities Act"). In connection with the offering, Esperion also expects to grant the initial purchasers of

the notes an option to purchase, for settlement within a 13-day period beginning on, and including, the date on which the notes

are first issued, up to an additional $30.0 million aggregate principal amount of the notes.

The notes will be senior unsecured obligations of Esperion that

are subordinated in right of payment to indebtedness, obligations and other liabilities under Esperion's revenue interest

purchase agreement, the revenue interests issued pursuant to such agreement, and any refinancing of the foregoing. Interest on

the notes will be payable semi-annually in arrears. The notes will be convertible under certain circumstances into cash, shares

of Esperion's common stock or a combination thereof, at Esperion's election. The notes will mature on November 15,

2025, unless earlier converted, redeemed or repurchased. The interest rate, conversion rate and other terms of the notes are to

be determined upon pricing of the offering.

In connection with the pricing of

the notes, Esperion expects to enter into privately negotiated capped call transactions with one or more of the initial purchasers

of the notes or their respective affiliates and/or other financial institutions (the "option counterparties"). The

capped call transactions are expected generally to reduce potential dilution to Esperion's common stock upon conversion of

any notes and/or offset any potential cash payments Esperion is required to make in excess of the principal amount of converted

notes, as the case may be, with such reduction and/or offset subject to a cap. If the initial purchasers of the notes exercise

their option to purchase additional notes, Esperion expects to enter into additional capped call transactions with the option counterparties.

In connection with establishing their

initial hedges of the capped call transactions, Esperion expects that the option counterparties or their respective affiliates

will purchase shares of Esperion's common stock and/or enter into various derivative transactions with respect to Esperion's

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 Esperion's common stock or the notes at that time.

In addition, the option counterparties

or their respective affiliates may modify their hedge positions by entering into or unwinding various derivatives with respect

to Esperion's common stock and/or purchasing or selling Esperion's common stock or other securities of Esperion in

secondary market transactions following the pricing of the notes and prior to the maturity of the notes (and are likely to do so

on each exercise date for the capped call transactions, which are expected to occur on each trading day during the 40 trading day

period beginning on the 41st scheduled trading day prior to the maturity date of the notes, or following any termination of any

portion of the capped call transactions in connection with any repurchase, redemption or early conversion of the notes). This activity

could also cause a decrease or avoid an increase in the market price of Esperion's common stock or the notes, which could

affect the ability of noteholders to convert the notes and, to the extent the activity occurs following conversion or 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.

In connection with the pricing of

the notes, Esperion also expects to enter into a prepaid forward stock purchase transaction (the "prepaid forward")

with one of the initial purchasers of the notes or its affiliate (the "forward counterparty"), pursuant to which Esperion

will purchase approximately $50.0 million of its common stock (based on the last reported sale price of Esperion's common

stock on the pricing date), for settlement on the date that is the maturity date of the notes, subject to any early settlement,

in whole or in part, of the prepaid forward. The prepaid forward is intended to facilitate privately negotiated transactions by

which investors in the notes will be able to hedge their investment.

In connection with establishing its

initial hedge of the prepaid forward, Esperion expects that the forward counterparty or its affiliate will enter into one or more

derivative transactions with respect to Esperion's common stock with purchasers of the notes concurrently with or after the

pricing of the notes. The prepaid forward is intended to allow investors to establish short positions that generally correspond

to (but may be greater than) commercially reasonable initial hedges of their investment in the notes. In the event of such greater

initial hedges, investors may offset such greater portion by purchasing Esperion's common stock on the day of pricing of

the notes. Facilitating investors' hedge positions by entering into the prepaid forward, particularly if investors purchase

Esperion's common stock on the pricing date, could increase (or reduce the size of any decrease in) the market price of Esperion's

common stock and effectively raise the initial conversion price of the notes.

In addition, the forward counterparty or its affiliate may modify

its hedge position by entering into or unwinding one or more derivative transactions with respect to Esperion's common stock

and/or purchasing or selling the common stock or other securities of Esperion in secondary market transactions at any time following

the pricing of the notes and prior to the maturity of the notes. These activities could also cause or avoid an increase or a decrease

in the market price of Esperion's common stock or the notes.

Esperion intends to use a portion of the net proceeds from the

offering to pay the cost of the capped call transactions and to finance the prepaid forward. Esperion intends to use the remainder

of the net proceeds from the offering for general corporate purposes, including potential in-licensing opportunities. If the option

granted to the initial purchasers to purchase additional notes is exercised, Esperion expects to use a portion of the net proceeds

from the sale of additional notes to enter into additional capped call transactions. Esperion expects to use the remaining net

proceeds for general corporate purposes as described above.

The notes will only be offered to qualified institutional buyers

pursuant to Rule 144A under the Securities Act. Neither the notes nor the shares of Esperion's common stock potentially

issuable upon conversion of the notes, if any, have been, or will be, registered under the Securities Act or the securities laws

of any other jurisdiction, and unless so registered, may not be offered or sold in the United States except pursuant to an applicable

exemption from such registration requirements.

This announcement is neither an offer to sell nor a solicitation

of an offer to buy any of these securities and shall not constitute an offer, solicitation or sale in any jurisdiction in which

such offer, solicitation or sale is unlawful.
