“The Offer and withdrawal rights expired as scheduled at
12:00 midnight, New York City time, at the end of the day on September 30, 2020. The Depositary has advised Purchaser that, as of the Expiration Time, 100,595,118 Shares were validly tendered and not validly withdrawn pursuant to the Offer,

Guaranteed Delivery had been received for 5,761,554 Shares, representing approximately 4.5 percent of then outstanding Shares on a fully-diluted basis. As the Minimum Condition and each of the other Offer Conditions have been satisfied,
Purchaser has accepted for payment all Shares that were validly tendered and not validly withdrawn pursuant to the Offer.
Following the
expiration of the Offer and acceptance for payment of the Shares validly tendered and not validly withdrawn pursuant to the Offer, on October 1, 2020, Johnson & Johnson, Momenta and Purchaser consummated the Merger pursuant to the
terms of the Merger Agreement in accordance with Section 251(h) of the DGCL, without a vote on the adoption of the Merger Agreement by Momenta stockholders, with the separate corporate existence of Purchaser ceasing and Momenta continuing as
the surviving corporation in the Merger under the name “Momenta Pharmaceuticals, Inc.”, thereby becoming a wholly owned subsidiary of Johnson & Johnson.

the Offer or (c) Shares owned by any stockholders who have properly and validly demanded their appraisal rights in compliance with Section 262 of the DGCL) was converted into the right to receive the Offer Price, without interest and less
any required withholding taxes. The Shares will be delisted from the Nasdaq Global Select Market and will be deregistered under the Exchange Act.
