(Commission File No. 001-36463)

The following are excerpts from the 2020 Sustainability Report (the “Report”) of Pioneer Natural Resources Company (the “Company” or “Pioneer”). The excerpts contain only those portions of the Report relating to the proposed acquisition of Parsley Energy, Inc. by Pioneer:

Letter from the CEO, p. ii

During the drafting of this year’s report, we announced the acquisition of Parsley Energy (Parsley). Like Pioneer, Parsley shares a commitment to ESG matters and demonstrates impressive environmental performance. Parsley is a Permian pure-play company, and a large portion of its operating footprint is contiguous to Pioneer’s, which is expected to allow the combined company to realize both operational and environmental synergies. Minimizing air emissions is a shared priority for Pioneer and Parsley – and Pioneer is committed to continue being a leader among U.S. oil and gas producers after the companies are combined.

As I have stated publicly on many occasions, flaring of associated natural gas is a “black eye” for the industry in the Permian Basin. We are committed to ending “routine” flaring in the Permian by 2030 in conjunction with the World Bank’s recommendation. We aspire to reach this goal by 2025. As part of this commitment, Pioneer will only bring an oil well onto production when it is connected to a midstream partner’s sales pipeline for the associated natural gas. Pioneer continues to be a leader in this area with a flaring intensity rate of less than one percent. Beginning with a 2019 baseline, Pioneer is establishing aggressive targets for reductions in our GHG emissions, methane emissions and flaring intensities for the next 10 years, taking into account the addition of Parsley’s assets.

Letter from the Chairman, p. iii

As Scott mentioned in his letter, 2020 has proved to be a challenging year for the oil and gas industry. Nevertheless, Pioneer continues to excel – drilling the best wells in the Permian Basin, maintaining a strong balance sheet and returning capital to our investors – and we have done so in alignment with stakeholder expectations on ESG matters. Our combination with Parsley will allow us to continue to deliver best-in-class operational and ESG performance for decades to come. While Scott focused on the tremendous progress Pioneer continues to make on environmental issues, I will address Pioneer developments in both social and governance matters.

Target Setting, pp. vi-vii

Pioneer has set Emissions Targets aligned with the TCFD’s criteria for target-setting, for our operated assets, from a 2019 emissions baseline, to:

Limit our annual flaring intensity to less than 1% including Parsley Energy assets by year-end 2022

Our Company, p. 1

On October 20, 2020, Pioneer and Parsley Energy, Inc. announced an agreement under which Pioneer will acquire all of the outstanding shares of Parsley in an all-stock transaction valued at approximately $7.6 billion. Following closing of the acquisition, Pioneer will hold approximately 960,000 net acres in the Permian Basin and will be the premier independent operator in the basin.

Emissions Targets, p. 19

Pioneer has established four GHG emissions-related targets aligned with the TCFD’s criteria for target setting. We have committed to the following long-term targets for our operated assets, from a full-year 2019 emissions baseline to:

 

•

Limit our annual production flaring intensity to less than 1% of our natural gas produced (while striving to bring Parsley assets to this level by year-end 2022)
