ADP Informed By Pershing That It Wants Five Seats on 10-Member Board and CEO Change; ADP Board Rejects Pershing's Request to Extend Director Nomination Deadline

ROSELAND, NJ -- (Marketwired) -- 08/04/17 -- ADP (NASDAQ: ADP) today issued the following statement regarding ADP's recent communications from Pershing Square Capital Management that Pershing is seeking effective control of ADP through five Board seats at ADP's 2017 Annual Meeting as well as a CEO change.

"Pershing first contacted ADP on August 1, and William Ackman said it beneficially owns 8% of ADP, largely in derivatives. Mr. Ackman requested that ADP extend the August 10 deadline for nomination of directors by 30 to 45 days and said he planned to nominate five directors, including himself, to ADP's 10-member Board. He also said CEO Carlos Rodriguez should be replaced."

"ADP is open to constructive input from our shareholders, and our Board respects the right of shareholders to nominate directors. However, ADP has a clearly defined Board nomination process, and the 2017 deadline for director nominations has been public for nearly a year. The Board has unanimously determined that it is not in the best interests of ADP or its other shareholders to accede to Pershing Square's last-minute request for an extension."

"Since Carlos Rodriguez became CEO nearly six years ago, ADP's total shareholder return of 202%1 is well in excess of the S&P 500 TSR of 128%2 -- and is many multiples of Pershing's TSR of 29%3."

"ADP has a strong and independent Board, including four new directors who have joined since 2014: Michael Gregoire, CEO of CA Technologies; Peter Bisson, former global leader of McKinsey's High Tech Practice; William Ready, EVP and Chief Operating Officer of PayPal; and Sandra Wijnberg, Executive Advisor and former Partner of Aquiline Holdings. These directors have deep expertise in technology, operations and finance and provide important perspective on advancing ADP's global strategy."

"We believe our current Board has an effective balance of leadership continuity and fresh perspectives that will help us to continue this strong track record of delivering value to shareholders while successfully executing on our 'All in on HCM' strategy."

Morgan Stanley & Co. is acting as financial advisor and Paul, Weiss, Rifkind, Wharton & Garrison LLP is acting as legal advisor to ADP.

1 Market data is intraday on July 27, prior to rumors of Pershing Square's investment in ADP; ADP TSR of 202% assumes shareholders have held their CDK shares since it was spun off from ADP on October 1, 2014 and all ADP and CDK dividends have been reinvested; if CDK were valued as a dividend at the spinoff date and reinvested in ADP, ADP TSR is 190%.
2 Market data as of close on July 26; S&P 500 returns also include dividends.
3 Pershing Square L.P. returns from January 1, 2012 through December 31, 2016.
