– Proceeds to be used to repurchase or repay 2026 convertible notes prior to or at maturity –
– Offering to include buyback of common stock –
The Notes will be general senior unsecured obligations of PTC and will accrue interest payable semiannually in arrears. The Notes will mature on June 15, 2031, unless earlier converted, repurchased or redeemed. Upon conversion, PTC will pay or deliver, as the case may be, cash, shares of its common stock or a combination of cash and shares of its common stock, at PTC's election. The interest rate, initial conversion rate and other terms of the Notes will be determined at the time of pricing of the Offering.
PTC expects to use net proceeds from the Offering for repurchases of a portion of its
In connection with the concurrent share repurchase described above, PTC expects to repurchase shares of its common stock sold short by initial investors in the Offering in privately negotiated transactions effected with or through one of the initial purchasers or its affiliate at a purchase price per share expected to be equal to the closing price per share of PTC's common stock on the pricing date of the Offering. These repurchases could increase (or reduce the size of any decrease in) the market price of PTC's common stock or the Notes. This activity could affect the market price of PTC's common stock prior to, concurrently with or shortly after the pricing of the Notes, and could result in a higher effective conversion price for the Notes.
PTC may repurchase for cash a portion of the 2026 Notes concurrently with the Offering pursuant to one or more separate and individually negotiated transactions with one or more holders of the 2026 Notes (each, a "concurrent note repurchase transaction"). The terms of each concurrent note repurchase transaction will depend on a variety of factors, including the market price of PTC's common stock and the trading price of the 2026 Notes at the time of the repurchase, if any. No assurance can be given as to how much, if any, of the 2026 Notes will be repurchased or the terms on which they will be repurchased. This press release is not a notice of redemption or an offer to repurchase the 2026 Notes, and the Offering of the Notes is not contingent upon the repurchase of any of the 2026 Notes.
In connection with any repurchase of the 2026 Notes, PTC expects that holders of the 2026 Notes who agree to have their 2026 Notes repurchased may enter into or unwind various derivatives with respect to PTC's common stock and/or purchase shares of PTC's common stock concurrently with or shortly after the pricing of the Notes. In particular, PTC expects that many holders of the 2026 Notes employ a convertible arbitrage strategy with respect to the 2026 Notes and have a short position with respect to PTC's common stock that they would close out through purchases of PTC's common stock and/or the unwinding of various derivatives with respect to PTC's common stock, as the case may be, in connection with PTC's repurchase of the 2026 Notes, if any. This activity could increase (or reduce the size of any decrease in) the market price of PTC's common stock, which may also affect the trading price of the Notes at that time and could result in a higher effective conversion price of the Notes. PTC cannot predict the magnitude of such market activity or the overall effect it will have on the price of the Notes or PTC's common stock.
The offer of Notes will be made only by means of a private offering memorandum. The offer and sale of the Notes and any shares of PTC's common stock issuable upon conversion of the Notes have not been, and will not be, registered under the Securities Act or any other securities laws, and the Notes and any such shares cannot be offered or sold except pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and any other applicable securities laws.
This press release does not constitute an offer to sell, or the solicitation of an offer to buy, the Notes or any shares of PTC's common stock issuable upon conversion of the Notes, nor will there be any sale of the Notes or any such shares, in any state or other jurisdiction in which such offer, sale or solicitation would be unlawful.
