SEATTLE, June 17, 2026 (GLOBE NEWSWIRE) -- Adaptive Biotechnologies Corporation (“Adaptive Biotechnologies”) (Nasdaq: ADPT) today announced the pricing of its offering of
The notes will be senior, unsecured obligations of Adaptive Biotechnologies. The notes will not bear regular interest, and the principal amount of the notes will not accrete. The notes will mature on July 1, 2031, unless earlier repurchased, redeemed or converted. Before April 1, 2031, noteholders will have the right to convert their notes only upon the occurrence of certain events. From and including April 1, 2031, noteholders may convert their notes at any time at their election until the close of business on the second scheduled trading day immediately before the maturity date. Adaptive Biotechnologies will settle conversions by paying or delivering, as applicable, cash, shares of its common stock or a combination of cash and shares of its common stock, at Adaptive Biotechnologies’s election. The initial conversion rate is 41.48 shares of common stock per
The notes will be redeemable, in whole or in part (subject to certain limitations), for cash at Adaptive Biotechnologies’s option at any time, and from time to time, on or after July 1, 2029 and on or before the 40th scheduled trading day immediately before the maturity date, but only if the last reported sale price per share of Adaptive Biotechnologies’s common stock exceeds
If a “fundamental change” (as defined in the indenture for the notes) occurs, then, subject to a limited exception, noteholders may require Adaptive Biotechnologies 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 special interest and additional interest, if any, to, but excluding, the applicable repurchase date.
Adaptive Biotechnologies estimates that the net proceeds from the offering will be approximately
In connection with the pricing of the notes, Adaptive Biotechnologies has been advised that J. Wood Capital Advisors LLC (“JWCA”), Adaptive Biotechnologies’s financial advisor with respect to the offering, has agreed to purchase approximately
In connection with the pricing of the notes, Adaptive Biotechnologies entered into privately negotiated capped call transactions with one or more of the initial purchasers or their affiliates or one or more other financial institutions (the “option counterparties”). The capped call transactions will cover, subject to anti-dilution adjustments substantially similar to those applicable to the notes, the number of shares of Adaptive Biotechnologies’s common stock underlying the notes. If the initial purchasers exercise their option to purchase additional notes, then Adaptive Biotechnologies expects to enter into additional capped call transactions with the option counterparties.
The cap price of the capped call transactions will initially be
The capped call transactions are expected generally to reduce the potential dilution to Adaptive Biotechnologies’s common stock upon any conversion of the notes and/or offset any potential cash payments Adaptive Biotechnologies is required to make in excess of the principal amount of converted notes, as the case may be, upon conversion of the notes. If, however, the market price per share of Adaptive Biotechnologies’s common stock, as measured under the terms of the capped call transactions, exceeds the cap price of the capped call transactions, there would nevertheless be dilution and/or there would not be an offset of such potential cash payments, in each case, to the extent that such market price exceeds the cap price of the capped call transactions.
In connection with establishing their initial hedges of the capped call transactions, the option counterparties or their respective affiliates expect to enter into various derivative transactions with respect to Adaptive Biotechnologies’s common stock and/or purchase shares of Adaptive Biotechnologies’s common stock concurrently with or shortly after the pricing of the notes. This activity, as well as the JWCA Purchase, could increase (or reduce the size of any decrease in) the market price of Adaptive Biotechnologies’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 Adaptive Biotechnologies’s common stock and/or purchasing or selling Adaptive Biotechnologies’s common stock or other securities of Adaptive Biotechnologies in secondary market transactions following the pricing of the notes and prior to the maturity of the notes (and (x) are likely to do so during any observation period related to a conversion of notes or following any repurchase of notes by Adaptive Biotechnologies in connection with any fundamental change and (y) may do so following any repurchase of notes by Adaptive Biotechnologies other than in connection with any fundamental change). This activity, as well as the JWCA Purchase, could also cause or avoid an increase or decrease in the market price of Adaptive Biotechnologies’s common stock or the notes, which could affect the 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 number of shares and value of the consideration that noteholders will receive upon conversion of the notes.
As described above, Adaptive Biotechnologies intends to use a portion of the net proceeds of the offering to repurchase shares of its common stock concurrently with the pricing of the offering in privately negotiated transactions. These repurchases, and any other repurchases of shares of Adaptive Biotechnologies’s common stock, may increase, or reduce the size of a decrease in, the trading price of Adaptive Biotechnologies’s common stock, and repurchases executed concurrently with the pricing of the offering may have affected the initial terms of the notes, including the initial conversion price.
The offer and sale of the notes and any shares of 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 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.
