Item 1. Security and Issuer
The class of equity security to which this statement on Schedule 13D
relates is the common stock (the "Securities") of Pioneer Natural Resources
Company, a Delaware corporation (the "Issuer"). The Issuer has its principal
executive offices located at 5205 N. O'Connor Blvd., Suite 200, Irving, Texas
75039.
Item 2. Identity and Background
Subparagraphs (a), (b), and (c). This statement is being filed by
Southeastern Asset Management, Inc. ("Southeastern"), an investment advisor
registered with the Securities & Exchange Commission under the Investment
Advisers Act of 1940, as amended. The address of its principal office is 6410
Poplar Avenue, Suite 900, Memphis, Tennessee 38119. Southeastern serves as an
investment advisor to various individual clients, institutions(including
qualified retirement plans), endowment funds and to Longleaf Partners Fund, a
series of Longleaf Partners Funds Trust, a registered investment company
organized as a Massachusetts business trust and having three series or
portfolios. Longleaf Partners Fund, which is joint filer of this Schedule 13D,
may be reached c/o Southeastern Asset Management, Inc., 6410 Poplar Avenue,
Suite 900, Memphis, Tennessee 38119.
The Securities of the Issuer reported in Item 5 herein were acquired
on behalf of the investment advisory clients of Southeastern Asset Management,
Inc., including Longleaf Partners Fund, under sole or shared discretionary
authority granted Southeastern. None of the Securities are owned by or on
behalf of Southeastern or by any of its directors or officers, or any Trustees
or officers of Longleaf.
This statement is also being filed by Mr. O. Mason Hawkins, Chairman of
the Board and Chief Executive Officer of Southeastern, in the event he could be
deemed to be an indirect beneficial owner of the Securities reported by
Southeastern through the exercise of voting control and/or dispositive power
over the Securities as the result of his official positions or ownership of
voting securities of Southeastern. Neither Southeastern nor Mr. Hawkins owns
any Securities for its or his own account and each disclaims beneficial
interest in any of the Securities reported herein.
(d) During the last five years, neither Southeastern nor Longleaf
Partners Fund, nor Mr. Hawkins has been convicted in any criminal proceeding.
(e) During the last five years, neither Southeastern nor Longleaf
Partners Fund, nor Mr. Hawkins has been a party to any civil or administrative
proceeding involving any alleged violations of any securities laws except as
follows: in February 2004, Southeastern and Longleaf Partners Small-Cap Fund
were named in a Complaint filed by The MONY Group, Inc. (MONY) in the US
District Court for the Southern District of New York alleging that Southeastern
and the Small-Cap Fund had violated Sections 14(a) and 13(d) of the Securities
Exchange Act of 1934 with respect to their activities opposing the acquisition
of MONY by AXA Financial. MONY obtained an injunction against Southeastern and
the Small-Cap Fund enjoining distribution of a duplicate copy of MONY's proxy
card, a strategy Southeastern and the Small-Cap Fund's legal counsel had first
reviewed with the SEC's Division of Corporate Finance and received verbal
assurance that such a strategy was permitted if certain conditions were
satisfied. Even though Southeastern and the Small-Cap Fund satisfied the
conditions outlined by the SEC, in light of the injunction, neither of them
actually sent a duplicate of MONY's proxy card. At a May 18, 2004 meeting, MONY
shareholders approved the acquisition by AXA, and MONY subsequently dismissed
their lawsuit against Southeastern and the Small-Cap Fund with prejudice.
(f) Southeastern is a corporation organized and existing under the
laws of the State of Tennessee; Longleaf Partners Funds Trust, of which
Longleaf Partners Fund is a series, is a Massachusetts business trust. Mr.
Hawkins is a citizen of the United States. The names, business addresses, and
principal occupations of each director and executive officer of Southeastern,
and each Trustee of Longleaf Partners Fund are set forth in Schedule I.
Item 3. Source and Amount of Funds or Other Consideration
The respective investment advisory clients of Southeastern used
approximately $628,377,393 in the aggregate to purchase the Securities reported
in this filing. All assets used to purchase Securities were assets of these
respective clients and none were assets of Southeastern. In addition, none of
the proceeds used to purchase the Securities were provided through borrowings
of any nature.
Item 4. Purpose of Transaction
The Securities reported in this filing have been purchased and held
for investment purposes on behalf of client accounts over which Southeastern
has either sole or shared discretionary investment or voting power. The
Securities are reported by Southeastern and by Mr. O. Mason Hawkins, Chairman
of the Board and Chief Executive Officer in the event that either should be
deemed to be a member of a group under Section 13(d)(3) or the beneficial
owner of these Securities under the provisions of subparagraph (b)of Rule
13d-3 under the Securities Exchange Act of 1934. Beneficial ownership on the
part of Southeastern and Mr. Hawkins as members of a group or as beneficial
owners is expressly disclaimed, as permitted by Rule 13d-4. All purchases of
Securities were made for investment purposes only, in the ordinary course of
business of Southeastern as a registered investment advisor. Southeastern may
purchase additional Securities on behalf of clients in the future, or may
sell all or a part of the current holdings of the Securities.
Southeastern is engaged in the business of investment management of
its clients' assets and pursues an investment philosophy of identifying
undervalued situations and acquiring positions in undervalued companies on
behalf of its clients. In pursuing this investment philosophy, Southeastern
analyzes the operations, capital structure and markets of companies in which
its clients invest and continuously monitors the business operations of such
companies through analysis of financial statements and other public documents,
through discussions with knowledgeable industry observers, and with management
of such companies, often at management's invitation.
Southeastern qualifies as an institution which may elect to file
securities ownership reports required by the Securities Exchange Act of 1934 on
Schedule 13G and, as a routine matter, Southeastern utilizes Schedule 13G for
its reporting of the ownership positions held by its investment advisory
clients. As the result of investment analysis or the occurrence of events,
Southeastern may desire to participate in discussions with the particular
portfolio company's management or with third parties about significant matters
in which Southeastern may suggest possible courses of action to assist in
building corporate intrinsic value per share or to cause the Company's true
economic value to be recognized. In such situations, Southeastern may elect to
convert a filing on Schedule 13G to a filing on Schedule 13D in order to be
more active in corporate governance and management matters, and to have the
ability to enter into discussions with third parties concerning proposed
corporate transactions of a significant nature.
On March 18, 2009, Southeastern entered into a letter agreement (the
"Letter Agreement") with the Issuer regarding changes to its Board of Directors.
A copy of the Letter Agreement has been filed by the Issuer as Exhibit 10.1 to
its Form 8-K filed March 19, 2009, and is incorporated herein by reference.
Southeastern has recommended three persons to serve as Directors pursuant to the
Letter Agreement, and will continue to work with the Issuer to accomplish their
election (or, if applicable, their appointment) before the deadline set forth
in the Letter Agreement.
In order to maintain the flexibility to discuss various alternatives,
including any of the actions or transactions enumerated in clauses a through j
of Item 4 of Schedule 13D, with the Issuer's management, Board of Directors
and/or with third parties, Southeastern is maintaining its filing on Schedule
13D. Southeastern intends to discuss with management, the Board, as well as
various third parties opportunities to maximize the value of the company for
all shareholders.
Item 5. Interest In Securities Of The Issuer
(a) The aggregate number and percentage of Securities to which this
Schedule 13D relates is 22,854,957 shares of the common stock of the Issuer,
constituting approximately 19.8% of the 115,616,236 shares outstanding.

(b) Southeastern generally has the sole power to dispose of or to
direct the disposition of the Securities held for discretionary accounts of its
investment clients, and may be granted the sole power to vote or direct the
vote of such Securities; such powers may be retained by or shared with the
respective clients for shared or non-discretionary accounts. Shares held by
any Series of Longleaf Partners Funds Trust are reported in the "shared"
category.
(c) Purchase or sale transactions in the Securities during the past
sixty days are disclosed on Schedule II.
(d) The investment advisory clients of Southeastern have the sole
right to receive and, subject to notice, to withdraw the proceeds from the sale
of the Securities, and the sole power to direct the receipt of dividends from
any of the Securities held for their respective accounts. Such clients may
also terminate the investment advisory agreements without penalty upon
appropriate notice. Southeastern does not have an economic interest in any of
the Securities reported herein.
(e) Not applicable.
Item 6. Contracts, Arrangements, Understandings or
Relationships with Respect to Securities of the Issuer
The powers of disposition with respect to Securities owned by
discretionary private accounts of Southeastern are established in written
investment advisory agreements between clients and Southeastern, which are
entered into in the normal and usual course of the business of Southeastern
as a registered investment advisor and which are generally applicable to all
securities purchased for the benefit of each such discretionary private
account. There are no special or different agreements relating to the
Securities of the Issuer.
The written investment advisory agreements with clients generally do
not contain provisions relating to borrowing of funds to finance the
acquisition of the Securities, acquisition of control, transfer of securities,
joint ventures, or any of the other transactions listed in the instructions to
Item 7 of Schedule 13D other than voting of proxies. In connection with
voting, Southeastern may be allowed or directed to vote the proxies received
by accounts classified as "discretionary" or "shared" accounts; such authority
is generally retained by the clients for accounts classified as "non-
discretionary".
On March 18, 2009, Southeastern entered into a letter agreement (the "Letter
Agreement") with the Issuer regarding changes to its Board of Directors. A copy
of the Letter Agreement has been filed by the Issuer as Exhibit 10.1 to its
Form 8-K filed March 19, 2009, and is incorporated herein by reference.

Asset Management, Inc. and Longleaf Partners Fund. Schedule II. Transactions

Southeastern and Longleaf Partners Small-Cap Fund were named in a Complaint
filed by The MONY Group, Inc. (MONY) in the US District Court for the Southern
District of New York alleging that Southeastern and the Small-Cap Fund had
violated Sections 14(a) and 13(d) of the Securities Exchange Act of 1934 with
respect to their activities opposing the acquisition of MONY by AXA Financial.
MONY obtained an injunction against Southeastern and the Small-Cap Fund
enjoining distribution of a duplicate copy of MONY's proxy card, a strategy
Southeastern and the Small-Cap Fund's legal counsel had first reviewed with
the SEC's Division of Corporate Finance and received verbal assurance that
such a strategy was permitted if certain conditions were satisfied. Even
though Southeastern and the Small-Cap Fund satisfied the conditions outlined
by the SEC, in light of the injunction, neither of them actually sent a
duplicate of MONY's proxy card. At a May 18, 2004 meeting, MONY shareholders
approved the acquisition by AXA, and MONY subsequently dismissed their lawsuit
against Southeastern and the Small-Cap Fund with prejudice.
