Spinoff Stock Distribution

What happened to my BLUE shares? How many do I own of each company?
  • Upon distribution, you received one share of 2seventy bio (TSVT) common stock for every three shares of bluebird bio (BLUE) common stock that you held as of October 19, 2021, the record date for the distribution.
  • You still hold the same number of shares of BLUE common stock as you held prior to the distribution.
What happened to fractional shares of TSVT common stock that resulted from application of the distribution ratio?
  • Fractional shares are in the process of being liquidated and distributed by American Stock Transfer & Trust, LLC, the distribution agent, as cash to the holders of those fractional shares, subject to applicable tax withholding.
What are the material U.S. federal income tax consequences of the distribution?
  • Completing the spin as a tax-free transaction was an important priority to bluebird bio and 2seventy bio.
  • It was a condition to the distribution that bluebird bio receive a private letter ruling from the IRS and an opinion from Goodwin Procter LLP, both satisfactory to bluebird bio’s board of directors and both continuing to be valid, together confirming that the distribution, together with certain related transactions, subject to certain caveats, generally is tax-free for U.S. federal income tax purposes under Sections 355 and 368(a)(1)(D) of the Internal Revenue Code of 1986, as amended (the Code).
  • If the distribution, together with certain related transactions, qualifies as tax-free for U.S. federal income tax purposes under Sections 355 and 368(a)(1)(D) of the Code, then for U.S. federal income tax purposes, no gain or loss will be recognized by you and no amount will be included in your income upon receipt of shares of TSVT common stock pursuant to the distribution. You will, however, recognize gain or loss for U.S. federal income tax purposes with respect to cash received in lieu of a fractional share of TSVT common stock.
  • You should consult your own tax advisor as to the particular consequences of the distribution to you, including the applicability and effect of any U.S. federal, state and local tax laws, as well as non-U.S. tax laws. For more information regarding the material U.S. federal income tax consequences of the distribution and for information regarding the types of investors subject to special rules to whom the above may not apply, please see the Form 10 filed by 2seventy bio and declared effective by the Securities and Exchange Commission on October 18, 2021.
If I sold my shares of BLUE common stock after the record date but before the distribution date, did I receive the dividend?
  • Not if BLUE shares were sold on the “regular way” trading market (i.e., under the BLUE ticker). If you traded BLUE shares on the regular way market, you traded your BLUE shares away together with the accompanying right to receive TSVT shares in the distribution.
  • However, if you sold your BLUE shares on the “ex-distribution” trading market (i.e., under the BLUEV ticker), you traded your BLUE shares without the accompanying right to receive TSVT shares in the distribution.
  • There was also a “when issued” trading market for TSVT shares (i.e., under the TSVTV ticker). The when-issued market was simply a market for only the right to receive TSVT shares in the distribution, uncoupled from BLUE shares. People who owned BLUE shares as of the record date had the ability to trade the right to receive TSVT shares in the when-issued market.
  • The ex-distribution and when-issued trading markets were suspended as of market closing on November 4, 2021, the distribution date.
Did I receive a dividend if I bought shares after the record date but before the distribution date?
  • Yes, if you purchased shares of BLUE common stock on the “regular way” trading market.
  • No, if you purchased shares of BLUE common stock on the “ex-distribution” trading market.
How do I determine my adjusted tax basis in bluebird and 2seventy related to the effects of the 2seventy distribution?
  • Please click here for a copy of the completed Form 8937 that includes a general summary regarding the application of certain U.S. federal income tax laws and regulations relating to the effects of the TSVT Distribution on the tax basis of BLUE stock and the allocation of tax basis between the stock of BLUE and TSVT following the TSVT Distribution. The information contained herein does not constitute tax advice and does not purport to be complete or to describe the consequences that may apply to particular categories of shareholders. Neither BLUE nor TSVT provides tax advice to its shareholders. You are urged to consult your own tax adviser regarding the particular consequences of the TSVT Distribution to you, including the applicability and effect of all U.S. federal, state and local, and foreign tax laws.
