Explanatory Note
On October 16, 2014, PTC Therapeutics, Inc., a Delaware corporation
(the "Issuer") announced the closing of an underwritten public offering
(the "Offering") of 3,000,000 shares of its Common Stock, $0.001 par value
per share (the "Common Stock"). This Amendment No. 1 ("Amendment No. 1")
to the Schedule 13D, filed with the SEC on July 3, 2013 on behalf of the
following (collectively, the "Reporting Persons"): (1) Brookside Capital
Partners Fund, L.P., a Delaware limited partnership ("Partners Fund"),
whose sole general partner is Brookside Capital Investors, L.P., a
Delaware limited partnership ("Brookside Investors"), whose sole
general partner is Brookside Capital Management, LLC, a Delaware
limited liability company ("Brookside Management"); and (2) Brookside
Capital Trading Fund, L.P., a Delaware limited partnership
("Trading Fund"), whose sole general partner is Brookside Capital
Investors II, L.P., a Delaware limited partnership ("Brookside
Investors II"), whose sole general partner is Brookside Management
(the "Original Schedule 13D"), is filed to reflect the percentage change
in the Reporting Persons' beneficial ownership as a result of the Offering
and the purchases made by the Trading Fund described in Item 4 of this
Amendment No. 1. This Amendment No. 1 amends and supplements the Original
Schedule 13D only to the extent provided herein and all other items in the
Original Schedule 13D remain unchanged.
Item 4. Purpose of Transaction
Item 4 is hereby amended and supplemented to add the following:
The Trading Fund made seven purchases from November 18, 2013 through
February 13, 2014, totaling 528,692 shares of Common Stock from the
Issuer for an aggregate purchase price of $12,082,350.29
(before fees and expenses) ("Additional Purchases") and one sale on
October 15, 2014, totaling 102,392 shares of Common Stock from the
Issuer ("Sale"). Following the Additional Purchases and subsequent
Sale, the Reporting Persons hold, in aggregate, 2,759,633 shares of
Common Stock.
The purpose of the Additional Purchases described above is for
investment purposes and the Additional Purchases were made in the
ordinary course of business and were not made for the purpose of acquiring
control of the Issuer.
Item 5. Interest in Securities of the Company
Item 5 is amended and restated in its entirety as follows:
(a) - (c) The information contained on the cover pages to this Schedule
13D/A is hereby incorporated herein by reference. As reported in the

(the "2014 Prospectus"), there are 33,102,647 shares of Common Stock
outstanding following the Offering. The Trading Fund beneficially owns

outstanding Common Stock, and the Partners Fund beneficially owns 1,083,333
shares of Common Stock, representing 3.27% of the Issuer's outstanding
Common Stock. Collectively, the Reporting Persons beneficially own
2,759,633 shares of Common Stock, representing 8.34% of the Issuer's
outstanding Common Stock.
Brookside Investors, as the sole general partner of the Partners Fund,
may be deemed to share voting and dispositive power with respect to 1,083,333
shares of Common Stock currently held by the Partners Fund, representing 3.27%
of the shares of the Issuer's outstanding Common Stock. Brookside Investors II,
as the sole general partner of the Trading Fund, may be deemed to share voting
and dispositive power with respect to 1,676,300 shares of Common Stock
currently held by the Partners Fund, representing approximately 5.06% of the
Issuer's outstanding Common Stock. The filing of this Statement shall not be
construed as an admission that Brookside Investors and Brookside Investors II
are, for the purpose of Section 13(d) of the Exchange Act, the beneficial
owners of such shares held by the Partners Fund and the Trading Fund.
Brookside Management, as the sole general partner of Brookside Investors
and Brookside Investors II, may be deemed to share voting and dispositive power
with respect to 2,759,633 shares of Common Stock currently held by the Partners
Fund and the Trading Fund, representing 8.34% of the shares of Common Stock
outstanding. The filing of this Statement shall not be construed as an
admission that Brookside Management is, for the purpose of Section 13(d) of
the Exchange Act, the beneficial owner of such shares held by the Partners
Fund and the Trading Fund.
(d) Except as otherwise described in this Item 5, no one other than the
Partners Fund and the Trading Fund has the right to receive, or the power
to direct the receipt of, dividends from, or the proceeds from the sale of,
any of the securities of the Issuer beneficially owned by the
