At 5:00 p.m. New York City time, on

Parent and Purchaser expect to complete the acquisition of SC on January 31, 2022 by consummating
the Merger pursuant to the Merger Agreement without a meeting of SC’s stockholders in accordance with Section 251(h) of the DGCL. At the Merger Effective Time, each outstanding Share (other than Shares owned by SC, any of its subsidiaries,

interest and subject to deduction for any required withholding taxes.
As a result of the Merger, the Shares will be delisted and will
cease to trade on the NYSE. Parent and SC intend to take steps to cause the termination of the registration of the Shares under the Exchange Act and suspend all of SC’s reporting obligations under the Exchange Act as promptly as practicable.
On January 28, 2022, Parent issued a press release announcing the expiration and results of the Offer. A copy of the press release
is attached as Exhibit (a)(5)(ii) hereto and is incorporated herein by reference.
