DOVER ANNOUNCES APERGY INVESTOR DAY AND FILING OF FORM 10 REGISTRATION STATEMENT FOR PLANNED SPIN-OFF

Apergy Investor Day to be Held on April 3, 2018 

Separation from Dover Remains On-Track for Completion in Early May 2018

DOWNERS GROVE, Ill., March 26, 2018 - Dover (NYSE: DOV) announced today that Apergy Corporation ("Apergy") will host its first Investor Day on Tuesday, April 3, 2018, in New York City. Apergy has also filed its Form 10 registration statement with the U.S. Securities and Exchange Commission ("SEC") in connection with the previously announced spin-off from Dover. The filing is a key step in Dover's plan to separate Apergy into a standalone public company, which is on track for completion in early May 2018.

The filing contains important information on the businesses, financial position and results of Apergy. The filing will be updated with additional information in subsequent amendments as further information on the transaction is finalized prior to separation. Additional information on the financial and operational performance and strategy of Apergy will be provided at Apergy's April 3, 2018, Investor Day, which will be held in New York City, beginning at 1:00 pm ET.  The presentation will be available live to all interested parties via webcast. The webcast can be accessed on Dover's website, dovercorporation.com, and Apergy's website, apergy.com. The live webcast will begin at 1:00 p.m. ET on April 3, 2018. A replay of the webcast will be available for six months on both dovercorporation.com and apergy.com.

"We are very excited about our inaugural Apergy Investor Day and look forward to discussing our promising future," said Sivasankaran "Soma" Somasundaram, President and Chief Executive Officer of Dover's Energy segment, who will become President and Chief Executive Officer of Apergy. "The filing of the Form 10 represents an important milestone in the process toward establishing Apergy as an independent, publicly-traded company. With our differentiated technology, leading brands and superior customer service, Apergy will be well-positioned to deliver significant benefits to our stakeholders."

The separation remains subject to certain customary conditions, including, among others, assurance that the spin-off of Apergy will be tax-free to Dover and U.S. shareholders, the effectiveness of appropriate filings with the SEC and final approval by Dover`s Board of Directors.  Approval by Dover's shareholders is not required for completion of the separation.

The registration statement is accessible by searching for filings by Apergy Corporation (CIK: 1723089) on the SEC's Edgar reporting system, which can be found at http://www.sec.gov/edgar/searchedgar/companysearch.html.
