NextGen Healthcare Announces Proposed Convertible Senior Notes Offering

REMOTE-FIRST COMPANY/NEW YORK—(BUSINESS WIRE)—Oct. 27, 2022—NextGen Healthcare, Inc. (Nasdaq: NXGN), a leading provider of innovative, cloud-based healthcare technology solutions, today announced its intention to offer, subject to market and other conditions, $200,000,000 aggregate principal amount of convertible senior notes due 2027 (the “notes”) in a private offering to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”). NextGen Healthcare also expects to grant the initial purchasers of the notes an option to purchase, for settlement within a period of 13 days from, and including, the date the notes are first issued, up to an additional $30,000,000 principal amount of notes.

The notes will be senior, unsecured obligations of NextGen Healthcare, will accrue interest payable semi-annually in arrears and will mature on November 15, 2027, unless earlier repurchased, redeemed or converted. Noteholders will have the right to convert their notes in certain circumstances and during specified periods. NextGen Healthcare will settle conversions in cash and, if applicable, shares of its common stock.

The notes will be redeemable, in whole or in part (subject to certain limitations), for cash at NextGen Healthcare’s option at any time, and from time to time, on or after November 20, 2025 and before the 61st scheduled trading day immediately before the maturity date, but only if the last reported sale price per share of NextGen Healthcare’s common stock exceeds 130% of the conversion price for a specified period of time. The redemption price will be equal to the principal amount of the notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date.

If certain corporate events that constitute a “fundamental change” occur, then, subject to a limited exception, noteholders may require NextGen Healthcare to repurchase their notes for cash. The repurchase price will be equal to the principal amount of the notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the applicable repurchase date.

The interest rate, initial conversion rate and other terms of the notes will be determined at the pricing of the offering.

NextGen Healthcare expects to use up to $50 million of the net proceeds from the offering to repurchase shares of its common stock concurrently with the pricing of the offering in privately negotiated transactions effected through one of the initial purchasers or its affiliate. NextGen Healthcare intends to use the remainder of the net proceeds for general corporate purposes. The concurrent repurchases of shares of NextGen Healthcare’s common stock described above may result in NextGen Healthcare’s common stock trading at prices that are higher than would be the case in the absence of these repurchases, which may result in a higher initial conversion price for the notes NextGen Healthcare is offering.
