Roche and Spark Therapeutics, Inc. announce extension of tender offer for shares of Spark Therapeutics, Inc. to December 16, 2019

Roche (SIX: RO, ROG; OTCQX: RHHBY) and Spark Therapeutics, Inc. (NASDAQ: ONCE) (“Spark”) today announced that Roche has extended the offering period of its previously announced tender offer to purchase all of the outstanding shares of common stock (the “Shares”) of Spark for USD 114.50 per Share, net to the seller thereof in cash, without interest and subject to any withholding taxes required by applicable law and upon the terms and subject to the conditions set forth in the Offer to Purchase dated March 7, 2019 (as it may be amended and supplemented from time to time, the “Offer”).

Pursuant to the Agreement and Plan of Merger, dated as of February 22, 2019, by and among Roche Holdings, Inc., 022019 Merger Subsidiary, Inc., and Spark (as amended, the “Merger Agreement”), the Offer, which was previously scheduled to expire at 5:00 p.m., New York City time, on Tuesday, December 10, 2019, has been extended until 5:00 p.m., New York City time, on Monday, December 16, 2019, unless it is extended further under the circumstances set forth in the Merger Agreement. All terms and conditions of the Offer shall remain unchanged during the extended period.

The Offer was extended to provide additional time for the U.S. Federal Trade Commission (the “FTC”) and the UK Competition and Markets Authority (the “CMA”) to complete their previously disclosed reviews of Roche’s pending acquisition of Spark. The parties remain committed to the transaction and are working cooperatively and expeditiously with the FTC and the CMA.

Citibank, N.A., the depository for the Offer, has advised Roche that, as of 5:00 p.m., New York City time, on December 6, 2019, approximately 5,732,593 Shares of Spark (none of which were tendered by notice of guaranteed delivery) had been validly tendered and received, and not validly withdrawn, pursuant to the Offer, representing approximately 14.9% of Spark’s outstanding Shares. Stockholders who have already tendered their Shares of Spark do not have to re-tender their Shares or take any other action as a result of the extension of the expiration date of the Offer.

Closing of the tender offer is conditioned upon customary closing conditions, including the expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act, and there being validly tendered and received, and not validly withdrawn, a majority of the outstanding Spark Shares. As previously disclosed by Roche and Spark, Roche notified its pending acquisition of Spark to the UK Competition and Markets Authority (the “CMA”) on 18 October 2019. CMA’s Phase 1 review period is scheduled to end on December 16, 2019.

About Spark Therapeutics

Spark Therapeutics is a fully integrated, commercial company committed to discovering, developing and delivering gene therapies. The company challenges the inevitability of genetic diseases, including blindness, haemophilia, lysosomal storage disorders and neurodegenerative diseases.

Founded in March 2013 as a result of the technology and know-how accumulated over two decades at Children’s Hospital of Philadelphia (CHOP), Spark Therapeutics’ investigational therapies have the potential to provide long-lasting effects, dramatically and positively changing the lives of patients with conditions where no, or only palliative, therapies exist. Greater understanding of the human genome and genetic abnormalities have allowed Spark Therapeutics’ scientists to tailor investigational therapies to patients suffering from very specific genetic diseases. This approach holds great promise in developing effective treatments to a host of inherited diseases.

Spark Therapeutics is headquartered in Philadelphia, Pennsylvania.
