Re: Operating Engineers Construction Industry and Miscellaneous Pension Fund v. Pioneer Natural Resources Company, C.A. No. 2024-0101-SEM
Dear Counsel:
This letter opinion resolves Plaintiff’s exceptions to Senior Magistrate Molina’s
Final Report dated January 16, 2025 (the “Final Report”).1
I. BACKGROUND
I have reviewed this matter de novo, as I must,2 but I adopt Senior Magistrate
Molina’s clear and thorough statement of the factual background.3 The abbreviated
version of the facts is that Scott Sheffield founded Defendant Pioneer Natural
Resources in the late 1990s and was its CEO through 2023.4 Pioneer was a Delaware

corporation that explored for, developed, and produced oil, natural gas liquids, and
gas in West Texas.5 On October 10, 2023, ExxonMobil and Pioneer executed a merger
agreement, under which ExxonMobil agreed to acquire Pioneer in an all-stock
transaction valued at approximately $59.5 billion.6 Pioneer filed its proxy statement
with the SEC on January 8, 2024,7 and Pioneer’s stockholders approved the merger
on February 7, 2024.8 ExxonMobil announced that it had completed the acquisition
on May 3, 2024.9
Before the acquisition, Plaintiff Operating Engineers Construction Industry
and Miscellaneous Pension Fund beneficially owned Pioneer stock.10 In response to
the announcement of the transaction, Plaintiff served a demand to inspect Pioneer’s
books and records pursuant to Section 220 of the Delaware General Corporation
Law.11 The demand sought to investigate potential breaches of fiduciary duty by
Pioneer’s senior management and directors in connection with the merger.12
Plaintiff’s theory of possible wrongdoing is that Sheffield misled the Pioneer
Board of Directors in connection with its consideration of the merger. Pioneer had

announced Sheffield’s retirement on April 26, 2023.13 By August 2023, the Board was
considering two possible transactions: Pioneer’s acquisition of Party A; and
ExxonMobil’s acquisition of Pioneer.14 Of those two possibilities, only the deal with
ExxonMobil would trigger Sheffield’s change-in-control benefits.15 Plaintiff alleges
that Sheffield was improperly incentivized to pursue the acquisition by ExxonMobil
over the acquisition of Company A for that reason.16
In response to the Section 220 demand, Pioneer produced many hundreds of
pages of documents including Board minutes, materials presented to the Board by
Pioneer’s management and advisors, memoranda sent to the Board by Pioneer
management, engagement letters and relationship disclosures from the Board’s
financial advisors, and D&O questionnaire responses.17
Plaintiff filed this action in advance of the stockholder vote to preserve
standing.18 After Pioneer’s initial production, Plaintiff continued to seek emails and
text messages between Sheffield and ExxonMobil’s CEO and Executive Chair, Darren

identified in the Pre-Trial Order.19
At trial, in addition to pointing out Sheffield’s possible conflicts and leading
role in the merger negotiations, Plaintiff relied on a May 2, 2024 FTC Consent Order
to bolster its bid for emails and texts. According to the FTC complaint, Sheffield had
“campaigned to organize anticompetitive coordinated output reductions between and
among U.S. crude oil producers, and others, including the Organization of Petroleum
Exporting Countries (‘OPEC’).”20 The FTC asserted that Sheffield’s “sustained and
long-running strategy to coordinate output reductions” included his use of “text
messages” to “discuss[] crude oil market dynamics, pricing, and output.”21
In her Final Report, Senior Magistrate Molina ruled in favor of Pioneer. She
concluded that Plaintiff had failed to adequately allege a credible basis for possible
wrongdoing.22 She further concluded that Plaintiff had failed to demonstrate that
requested emails and text messages were necessary and essential, even if Plaintiff
had carried its burden to demonstrate a proper purpose.23

Plaintiff filed exceptions to the Final Report, which the parties fully briefed. 24

II. ANALYSIS
On exceptions, Plaintiff argues that the Senior Magistrate erred by concluding
that Plaintiff failed to meet the credible basis requirement. Plaintiff also argues that
the Senior Magistrate erred in setting the scope of inspection.
Plaintiff has met the credible basis requirement, in my view. A plaintiff must
demonstrate a credible basis to investigate possible wrongdoing, but the Delaware
Supreme Court described that standard as the “lowest possible burden of proof.”26 To
meet it, a stockholder need not prove that the wrongdoing “actually occurred” 27 nor
show that wrongdoing is even “probable.”28 Any such requirement “would completely
undermine the purpose of Section 220 proceedings, which is to provide shareholders
the access needed to make that determination in the first instance.”29 To state a

credible basis, a stockholder need only establish by a preponderance of the evidence
that there is a credible basis to suspect a possibility of wrongdoing.30 Given the
details in the demand and facts presented at trial, Plaintiff exceeded this low bar.
And the Senior Magistrate acknowledged whether Plaintiff had stated a credible
basis presented a “close call.”31
Although Plaintiff has met the credible basis requirement, it is not entitled to
additional documents, because I reach the same conclusion as the Senior Magistrate
as to scope.
Because this action was filed before the General Assembly amended Section
220 to import a new legal regime,32 decades of carefully crafted judge-made law
govern this scope analysis.
Under the prior regime, “[w]hen tailoring the production order, the court must
balance the interests of the stockholder and the corporation.”33 Delaware courts
struck this balance by limiting a stockholder-plaintiff’s inspection to those records
“essential and sufficient” to his stated purpose and by placing the burden of proof on
30 See AmerisourceBergen, 2020 WL 132752, at *6; see also Seinfeld, 909 A.2d at 118
(holding that a Section 220 plaintiff need only allege a “‘credible basis’ from which a court can infer that mismanagement, waste or wrongdoing may have occurred” (emphasis added)). 31 Final Report at 19:12–13.
32 See Del. S.B. 21, 153d Gen. Assem. (2025), codified at 8 Del. C. § 220.
33 AmerisourceBergen, 2020 WL 132752, at *24 (citing Sec. First Corp. v. U.S. Die
Casting & Dev. Co., 687 A.2d 563, 569 (Del. 1997)). C.A. No. 2024-0101-SEM July 28, 2025 Page 7 of 9
the stockholder.34 The essential-and-sufficient standard requires that, “where a § 220
claim is based on alleged corporate wrongdoing, and assuming the allegation is
meritorious, the stockholder should be given enough information to effectively
address the problem, either through derivative litigation or through direct contact
with the corporation’s directors and/or stockholders.”35
In the taxonomy of books and records, there are “Formal Board Materials,”
“Informal Board Materials,” and “Officer-Level Materials.”36 The scope of stockholder
inspection is typically limited to Formal Board Materials. As the Delaware Supreme
Court has explained, where “a company observes traditional formalities, such as
documenting its actions through board minutes, resolutions, and official letters, it
will likely be able to satisfy a Section 220 petitioner’s needs solely by producing those
books and records.”37
But a stockholder can inspect Informal Board Materials and Officer-Level
Materials if the stockholder “demonstrate[s] a need for broader inspection.”38 A

stockholder can demonstrate a need by, for example, showing a discrepancy between
public disclosures and Board materials or by showing that the Formal Board
Materials do not provide details as to key events.39
Here, Plaintiff has failed to identify the foothold needed to inspect beyond the
Formal Board Materials. Plaintiff contends that Sheffield “withheld key information
from the Board,” but Plaintiff does not specify what that key information might be.40
Plaintiff suggests that Sheffield had developed a “pattern” of discussing material
price terms with Woods without the Board’s permission, pointing to the Consent
Order as a reason to be suspicious of his use of text messages.41 But a fiduciary’s
allegedly ill-advised texts sent in one context does not entitle a stockholder to inspect
that fiduciary’s text for all purposes.
As the Senior Magistrate observed, the produced Board materials are
extensive.42 The mere possibility that some additional details might exist in informal
communications does not render those documents “necessary and essential” to
39 See, e.g., Palantir Techs., 203 A.3d at 742 (finding non-emails insufficient where
the defendant “did not honor traditional corporate formalities . . . and had acted through email in connection with the same alleged wrongdoing that [the plaintiff] was seeking to investigate”). 40 Compl. ¶ 33.

understanding the Board’s decision-making.43 Plaintiff argues that its demand for
electronic communications was “narrowly circumscribed,” 44 and that is a fair
description of Plaintiff’s request. But Plaintiff has not demonstrated that even this
targeted scope is necessary under the circumstances.

I overrule Plaintiff’s exceptions and adopt the Magistrate’s Final Report.
