     This Amendment No. 2 to the Schedule 13D supplements the information set
forth in the Schedule 13D filed by the Reporting Persons with the United
States Securities and Exchange Commission (the "SEC"), as amended from time
to time (the "Schedule 13D"), relating to the Common Stock, nominal value
$0.001 per share (the "Common Stock") of Bioverativ Inc., a Delaware
Corporation (the "Issuer"). The address of the principal executive offices of
the Issuer is 225 2nd Avenue, Waltham, MA 02451. Capitalized terms contained
herein but not otherwise defined shall have the meanings ascribed to such
terms in the Schedule 13D.

     The information set forth in response to each separate Item below shall
be deemed to be a response to all Items where such information is relevant.
The Schedule 13D is hereby supplementally amended as follows:

Item 5.    Interest in Securities of the Issuer

       (a) and (b).  Set forth below is the beneficial ownership of shares of
Common Stock of the Issuer for each person named in Item 2.  Shares reported
as beneficially owned by ValueAct Master Fund are also reported as
beneficially owned by (i) ValueAct Management L.P. as the manager of each
such investment partnership, (ii) ValueAct Management LLC, as General Partner
of ValueAct Management L.P., (iii) ValueAct Holdings, as the sole owner of
the limited partnership interests of ValueAct Management L.P. and the
membership interests of ValueAct Management LLC and as the majority owner of
the membership interests of VA Partners I and (iv) ValueAct Holdings GP, as
General Partner of ValueAct Holdings.  Shares reported as beneficially owned
by ValueAct Master Fund are also reported as beneficially owned by VA
Partners I, as General Partner of ValueAct Master Fund.  VA Partners I,
ValueAct Management L.P., ValueAct Management LLC, ValueAct Holdings and
ValueAct Holdings GP also, directly or indirectly, may own interests in one
or more than one of the partnerships from time to time.  Unless otherwise
indicated below, by reason of such relationship ValueAct Master Fund is
reported as having shared power to vote or to direct the vote, and shared
power to dispose or direct the disposition of, such shares of Common Stock,
with VA Partners I (only with respect to ValueAct Master Fund), ValueAct
Management L.P., ValueAct Management LLC, ValueAct Holdings and ValueAct
Holdings GP.

     As of the date hereof, the Reporting Persons may be deemed to be the
beneficial owner of 4,079,892 shares of Common Stock, representing
approximately 3.8% of the Issuer's outstanding Common Stock. All percentages
set forth in this Schedule 13D are based upon the Issuer's reported
108,159,852 outstanding shares of Common Stock as of May 1, 2017 as reported
in the Issuer's Form 10-Q for the quarterly period ended March 31, 2017.

     (c) The following table sets forth all transactions with respect to
shares of Common Stock effected in the previous sixty days to this Schedule
13D by the Reporting Persons, inclusive of any transactions effected through
4:00 p.m., New York City time, on July 17, 2017. Except as otherwise noted
below, all such transactions were purchases (or sales) of shares of Common
Stock effected in the open market.
