* The calculation is based on 42,904,381 shares of Common
Stock of WEX outstanding as of August 1, 2017, according to information set forth in WEX’s 2017Q2 10Q.
Information in respect of each Warburg Pincus Reporting Person
(as such term is defined in Amendment No. 1) is given solely by such Warburg Pincus Reporting Person, and no Warburg Pincus Reporting
Person has responsibility for the accuracy or completeness of information supplied by any other Warburg Pincus Reporting Person.
This Amendment No. 2 to Schedule 13D (this “
Amendment
No. 2
”) amends and supplements the Original Schedule 13D and Amendment No. 1 to Schedule 13D filed with the SEC on May
3, 2017 (the Amendment No. 1”) (the Original Schedule 13D and Amendment No. 1, together with Amendment No. 2, the “
Schedule
13D
”). The Schedule 13D relates to the shares of Common Stock of WEX
, wh
i
c
h
h
as its
pr
i
n
cipal
executive office at 97 Darling Avenue, South Portland, Maine 04106. This Amendment No. 2 constitutes an “exit filing”
for the Warburg Pincus Reporting Persons who, based on the transactions described below,
will
no longer be the beneficial owner of more than five percent of Common Stock of WEX
. All capitalized terms used but not defined
herein shall have the meanings ascribed to such terms in the Schedule 13D.
|
Item 4.
|
Purpose of Transaction
|
This Amendment No. 2 amends and restates
Item 4 of the Schedule 13D in its entirety as follows:
The Sellers acquired 4,011,672 shares of Common
Stock of WEX in partial consideration for the sale of Mustang Topco and WP Blocker in the Acquisition and, following consummation
of the Acquisition, certain of the Sellers contributed their shares of Common Stock of WEX to Mustang Holdco in exchange for units
of that entity. The Warburg Pincus Reporting Persons beneficially own the Common Stock of WEX as an investment. Subject to the
limitations described below in this Item 4, the Warburg Pincus Reporting Persons from time to time may decide to increase or decrease
their investment in WEX through transfers of shares of Common Stock of WEX or other capital stock of WEX in open market or private
transactions or otherwise. The timing and amount of any such increase or decrease may depend upon the price and trading volume
of shares of Common Stock of WEX, subsequent developments affecting WEX, WEX’s business and prospects, other investment and
business opportunities available to the Warburg Pincus Reporting Persons, general stock market and economic conditions, tax considerations
and other factors the Warburg Pincus Reporting Persons consider relevant. Pursuant to the Purchase Agreement, James C. Neary, was
also appointed to Class II of WEX’s board of directors (the “
Board
”) and the Compensation Committee thereof,
effective as of July 5, 2016.
On February 14, 2017, Mustang Holdco was succeeded by Mustang Holdco
II, which received the 3,850,810 shares of Common Stock of WEX previously held by Mustang Holdco for no additional consideration.
The 4,011,672 shares of Common Stock of WEX reported in the Schedule 13D as beneficially owned by the Warburg Pincus Reporting
Persons (as such term was defined therein) included 160,862 shares of Common Stock of WEX beneficially owned by third parties (the
“
Other Holders
”). On February 14, 2017, such shares were distributed to the Other Holders for no additional
consideration. Such shares are now directly held by the Other Holders, and no Warburg Pincus Reporting Person (as such term is
defined in this Amendment No. 2 and in the Schedule 13D), either directly or indirectly, holds such shares as of February 14, 2017.
On May 1, 2017, Mustang Holdco II sold 1,283,603 shares of Common
Stock of WEX at a price of $101.50 per share in an offering pursuant to Rule 144 under the Securities Act of 1933, as amended (the
“
Securities Act
”). As a result of such sale, the Warburg Pincus Reporting Persons beneficially owned 2,567,207
shares of Common Stock of WEX, representing approximately 5.98% of the outstanding Common Stock of WEX.
On August 14, 2017, Mustang Holdco II sold 2,390,000 shares of Common
Stock of WEX at a price of $102.25 per share in an offering pursuant to Rule 144 under the Securities Act. As a result of such
sale, the Warburg Pincus Reporting Persons beneficially own 177,207 shares of Common Stock of WEX, representing approximately less
than 1% of the outstanding Common Stock of WEX.
The information set forth in Item 3 of the Schedule
13D is hereby incorporated by reference in this Item 4.
The Investor Rights Agreement
As a condition to the closing of the Acquisition,
on July 1, 2016, WEX, the Sellers, WP Lexington II, WP XI Lexington-A, WP XI Lexington Partners-A, WP Co-Invest LLC, and certain
other members of Mustang Holdco entered into an investor rights agreement (the “
Investor Rights Agreement
”).
In connection with its receipt of shares of Common Stock of WEX from Mustang Holdco , Mustang Holdco II entered into a joinder
to the Investor Rights Agreement on February 14, 2017, which was attached as Exhibit 99.2 to the Amendment No. 1 and is incorporated
herein by reference. The Investor Rights Agreement sets forth certain agreements, including with respect to governance matters,
the exercise of registration rights, transfer restrictions, standstill restrictions and certain other matters.
The following is a description of the material
terms of the Investor Rights Agreement:
Board Representation.
Pursuant to the
Purchase Agreement and under the terms of the Investor Rights Agreement, WEX is obligated to cause one representative designated
by the Sellers and certain affiliates of WP LLC to whom the Sellers have transferred their shares in accordance with the terms
of the Investor Rights Agreement (“
WP
”), subject to certain qualifications, to be appointed to Class II of the
Board (any such director designated by WP, a “
WP Representative
”) and as a member of the Compensation Committee
or the Corporate Governance Committee, as agreed by WEX and WP in good faith. At each meeting of the stockholders of WEX at which
directors of WEX are to be elected and at which the WP Representative’s term expires, the Board will nominate and recommend
for election one WP Representative and will use its reasonable best efforts to cause such WP Representative to be elected as a
director. Upon the vacancy of a WP Representative, the Board will appoint another WP Representative to fill such vacancy. The WP
Representative will have the right to the same compensation, indemnification, advancement of expenses, insurance coverage, reimbursement
and other perquisites as other directors and will have customary rights to information and notice as other directors. The WP Representative
will resign and WEX’s obligations with respect to the appointment and nomination of such WP Representative will terminate
when the Board, by majority vote, requests the resignation of such WP Representative and the shares of Common Stock of WEX beneficially
owned by WP have had a market value of less than $200 million for 20 consecutive trading days (the “
Standstill Termination
Date
”).
Registration Rights.
The Investor Rights
Agreement provides WP with certain demand registration rights, including shelf registration rights, in respect of the Common Stock
of WEX held by them, subject to certain conditions. In addition, WP has piggyback rights with respect to certain registrations
of Common Stock of WEX. WEX is required to pay the expenses, other than underwriting discounts and commissions and transfer taxes,
associated with any registration of shares of Common Stock of WEX pursuant to the Investor Rights Agreement.
Transfer Restrictions
. The Investor Rights
Agreement prohibits any transfers of (x) any shares of Common Stock of WEX acquired pursuant to the Purchase Agreement and held
by WP until December 28, 2016 and (y) more than one-third of such shares of Common Stock of WEX until July 1, 2017, except, in
both cases, transfers (i) to certain permitted transferees, (ii) to another party pursuant to a tender offer, exchange offer, merger,
consolidation or other similar transaction recommended by the Board to the stockholders of WEX or (iii) in connection with any
merger, business combination or mandatory share exchange approved by the stockholders of WEX, subject to certain conditions and
exceptions. Parties to the Investor Rights Agreement also agreed not to transfer any shares of Common Stock of WEX for a certain
period of time in connection with certain offerings of equity securities of WEX.
Standstill Restrictions
. The Investor
Rights Agreement provides that, subject to certain exceptions, from July 1, 2016 until the Standstill Termination Date or earlier
material breach by WEX of any of its obligations under the Investor Rights Agreement, WP and WP LLC may not (without WEX’s
prior written consent) (1) acquire beneficial ownership of any shares of Common Stock of WEX if, after
such acquisition, WP LLC, WP and certain of their respective affiliates
would beneficially own, in the aggregate, a number of shares of Common Stock of WEX equal to ten percent (10%) or more of the number
of outstanding shares of Common Stock of WEX; (2) make or participate, directly or indirectly, in any solicitation of proxies or
otherwise seek to advise or influence any person or entity (other than a permitted transferee of WP) with respect to the voting
of any voting securities of WEX; (3) form, join or in any way participate in a “group” as defined in Section 13(d)(3)
of the Exchange Act (other than with other permitted transferees of WP) with respect to any voting securities of WEX; and (4) publicly
disclose any intention, plan or arrangement that is prohibited by or inconsistent with the foregoing.
The foregoing summary of the Investor Rights
Agreement is not intended to be complete and is qualified in its entirety by reference to the full text of the Investor Rights
Agreement, attached hereto as
Exhibit 2
, and incorporated herein by reference. The disclosure set forth in Item 3
of the Original Schedule 13D is incorporated herein by reference.
Additional Disclosure
Except as otherwise set forth herein, none of
the Warburg Pincus Reporting Persons nor, to their knowledge, any person listed in Schedule I to the Amendment No. 1 or in Schedule
I to the Original Schedule 13D, has any plans or proposals which relate to or would result in any transaction, event or action
enumerated in paragraphs (a) through (j) of Item 4 of the instructions to Schedule 13D.
Subject to the terms of the Investor Rights
Agreement, the Warburg Pincus Reporting Persons reserve the right to formulate other plans or make proposals which relate to or
would result in a transaction, event or action enumerated in paragraphs (a) through (j) of Item 4 of the instructions to Schedule
13D with respect to WEX, and take action in connection therewith, including a disposition of all or a portion of their investment
in WEX. Subject to the terms of the Investor Rights Agreement, the Warburg Pincus Reporting Persons may, at any time, reconsider
and change their plans or proposals relating to the foregoing with respect to WEX.
