Introduction

As previously disclosed, West Corporation, a Delaware corporation (the “Company” or “West”), entered into an Agreement and Plan of Merger (the “Merger Agreement”), dated as of May 9, 2017, with Mount Olympus Holdings, Inc., a Delaware corporation (“Parent”), and Olympus Merger Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of Parent (“Merger Sub”). On October 10, 2017 (the “Closing Date”), upon the terms and subject to the conditions set forth in the Merger Agreement and in accordance with the applicable provisions of the General Corporation Law of the State of Delaware, Merger Sub merged with and into the Company with the Company surviving as a wholly-owned subsidiary of Parent (the “Merger”). Parent is an affiliate of certain funds (the “Apollo Funds”) managed by affiliates of Apollo Management VIII, L.P.

The description of the Merger Agreement and related transactions (including, without limitation, the Merger) in this Form 8-K does not purport to be complete and is subject, and qualified in its entirety by reference to the full text of the Merger Agreement which is attached as Exhibit 2.1 to the Company’s Current Report on Form 8-K filed with the Securities and Exchange Commission (the “SEC”) on May 10, 2017 and incorporated herein by reference.

Item 2.01 Completion of Acquisition or Disposition of Assets.

On October 10, 2017, Parent completed the acquisition of the Company. Pursuant to the Merger Agreement, at the effective time of the Merger (the “Effective Time”), each share (a “Share”) of common stock of the Company, par value $0.001 per Share (“Company Common Stock”), issued and outstanding immediately prior to the Effective Time (other than (i) Shares held by stockholders of the Company who had properly exercised and perfected appraisal rights under Delaware law and (ii) Shares that were held in the treasury of the Company or owned of record by any wholly-owned subsidiary of the Company, Parent or any wholly-owned subsidiary of Parent (clauses (i) and (ii), the “Excluded Shares”)) was cancelled and extinguished and automatically converted into the right to receive $23.50 in cash, without interest (the “Merger Consideration”), subject to applicable tax withholding.

In addition, with respect to all outstanding options, stock unit awards and restricted stock awards under the Company’s equity plans, as a result of the Merger, at the Effective Time of the Merger:

For any stock unit awards that are subject to performance-based vesting conditions, the number of Shares subject to such awards that are earned based on performance were deemed to have been satisfied at 100% of the target level. In addition, any notional Shares accrued under the Company’s deferred compensation plan have been valued based on the Merger Consideration and notionally reinvested in one or more other “measurement funds” as defined under the deferred compensation plan.

The total amount of funds used to complete the Merger and related transactions and pay related fees and expenses was approximately $5.2 billion, which was funded through a combination of equity contributions from the Apollo Funds, cash of the Company and proceeds from the debt financing transactions.

In connection with the closing of the Merger, the Company notified the NASDAQ Global Select Market (“NASDAQ”) on October 10, 2017 that the certificate of merger has been filed with the State of Delaware and that, at the Effective Time, each Share (other than the Excluded Shares) was cancelled and extinguished and automatically converted into the right to receive Merger Consideration without interest thereon, subject to applicable tax withholding. In addition, the Company requested that NASDAQ delist the Company Common Stock after market close on October 10, 2017, and, as a result, trading of Company Common Stock on NASDAQ was suspended as of approximately 4:00 p.m., New York time, on October 10, 2017. The Company also requested NASDAQ to file with the SEC a notification of removal from listing and registration on Form 25 with the SEC to effect the delisting of the Company Common Stock from NASDAQ and the deregistration of the Company Common Stock under Section 12(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The Company intends to file with the SEC a Form 15 requesting the termination of registration of the Company Common Stock under Section 12(g) of the Exchange Act and the suspension of reporting obligations under Sections 13 and 15(d) of the Exchange Act.
