    SUMMARY **
    Antitrust Law
    The panel reversed the district court’s summary
    judgment in favor of CenterPoint Energy Services, Inc.
    (“CES”), a natural gas company, in a class action alleging
    that ten large natural gas companies colluded to fix retail
    natural gas prices in Wisconsin.
    CES was a wholly owned subsidiary of Reliant Energy,
    Inc. The plaintiff class alleged that certain Reliant entities –
    including CES – conspired with other natural gas
    conglomerates to fix retail natural gas prices.
    The panel held that Copperweld Corp. v. Independence
    Tube Corp., 
    467 U.S. 752
     (1984), supported the following
    rule: a wholly-owned subsidiary that engaged in coordinated
    activity in furtherance of the anticompetitive scheme of its
    parent and/or commonly owned affiliates is deemed to
    engage in such coordinated activity with the purposes of the
    single “economic unit” of which it was a part.
    The panel held that plaintiffs raised a triable issue of
    CES’s anticompetitive intent. Specifically, the panel held
    that: plaintiffs submitted evidence that Reliant’s “economic
    unit” had an anticompetitive purpose during the class period;
    such anticompetitive “purpose” could sustain liability under
    the federal Sherman Act with or without an additional
    finding of knowledge; and Reliant’s alleged illegal purposes
    are imputed to CES’s coordinated activities.

    has been prepared by court staff for the convenience of the reader.
    ARANDELL V. CENTERPOINT ENERGY SERVS.                3
    The panel held that plaintiffs’ evidence was sufficient to
    raise a triable issue of whether CES knowingly acted to
    further the alleged price-fixing scheme. The panel further
    held that any knowledge of the alleged price-fixing scheme
    that CES’s directors and officers acquired while
    concurrently acting as directors or officers of the other
    Reliant companies was imputable to CES as a matter of
    Wisconsin law.
    The panel held that plaintiffs submitted sufficient
    evidence to raise a genuine issue under the Sherman Act –
    and Wisconsin Statute § 133.03(1) – as to whether CES
    participated in coordinated activity in furtherance of the
    alleged inter-enterprise price-fixing conspiracy.

    OPINION
    BEA, Circuit Judge:
    Here we have a wholly owned subsidiary company
    which sold natural gas to Plaintiffs. It asserts that it acted
    innocently and without knowledge of its parent company’s
    price-fixing scheme, which had pumped up the price of that
    gas. Yes, the subsidiary company sold the gas at prices
    previously rigged by the parent, and yes, the subsidiary sent
    the profits back to the parent. But the subsidiary asserts there
    is no evidence that it knew the prices were inflated or that it
    had the purpose to carry out the price-fixing scheme. Under
    Wisconsin antitrust law, can the subsidiary be liable to
    Plaintiffs? Because Supreme Court precedent establishes
    that “a parent and a wholly owned subsidiary always have a
    ‘unity of purpose’” and thus act as a “single enterprise”
    whenever they engage in “coordinated activity,”
    Copperweld Corp. v. Indep. Tube Corp., 
    467 U.S. 752
    (1984) (emphasis added), we conclude that it can.
    I. BACKGROUND
    Most consumers of natural gas in North America are
    individuals or small businesses who buy their gas from local
    utility companies.       However, some larger and more
    sophisticated businesses bypass their local utility and
    purchase gas directly from the companies that sell gas to the
    local utilities. These large commercial customers enter
    contracts to buy agreed-upon quantities of gas and take
    delivery via high-volume gas pipelines. While these
    contracts typically specify the quantity to be delivered, the
    price is typically left to be determined by reference to the
    market price at the time of delivery, as reported in the latest
    price index published by a designated trade publication. For
    example, a contract might provide that the price of a delivery
    ARANDELL V. CENTERPOINT ENERGY SERVS.                              5
    of natural gas would be “the Inside FERC index plus $x.”
    Such contracts to purchase gas on the cash market and take
    physical delivery of natural gas are referred to as “physical”
    contracts (as opposed to financial or “futures” contracts). 1
    In the early 2000s, natural gas prices rose dramatically,
    due in part to manipulative trading practices of some of the
    nation’s largest natural gas conglomerates. In March 2003,
    the Federal Energy Regulatory Commission (FERC)
    published a report on “whether and, if so, the extent to which
    California and Western energy markets were manipulated
    during 2000 and 2001.” See FERC, Final Report on Price
    Manipulation in Western Markets: Fact-Finding
    Investigation of Potential Manipulation of Electric and
    Natural Gas Prices, at ES-1 (Mar. 2003), available at
    https://www.ferc.gov/legal/maj-ord-reg/land-docs/PART-I-
    3-26-03.pdf (“FERC Final Report”). The report “found
    significant market manipulation” by gas marketing
    companies such as Enron, for example. 
    Id.
     at ES-1–ES-2.
    In particular, FERC discovered widespread “efforts to
    manipulate price indices compiled by trade publications”
    1
    To protect against the risk that the price of natural gas will increase
    before the delivery date, many sophisticated gas purchasers seek to
    “hedge” by purchasing natural gas futures contracts—standardized
    contracts for the sale and purchase of natural gas at a specific price in the
    future—which are resolved financially (i.e., by selling the contractual
    interest for cash or otherwise liquidating the gas interest) rather than by
    taking delivery of gas. A properly executed hedging strategy negates
    any loss or gain on the physical purchase due to changes in the price of
    gas, as the physical gas customer stands in the position of a natural gas
    seller for purposes of the futures contract. Ideally, the “buy” position on
    the physical contract and the “sell” position on the futures contract
    counterbalance each other so that the physical gas purchaser is left with
    a net cost for natural gas equal to the price of natural gas at the time it
    entered the physical gas contract.

    primarily through “[r]eporting of false data” to the trade
    publications, “wash trading,” 2 and a trading activity known
    as “churning.” 3 
    Id.
     at ES-1–ES-5. The report determined
    that energy trading companies had few, if any, internal
    controls in place to ensure the accuracy of the data reported
    to trade publications. FERC Final Report at III-3.
    Ultimately, the report found that price manipulation was a
    substantial cause of “[d]ysfunctions in the natural gas
    market” which led to “extraordinary” increases in gas prices
    in 2000 and 2001. 
    Id.
     at ES-1.
    Various plaintiff groups filed class-action lawsuits
    around the country, in both state and federal courts, and
    alleged that natural gas traders manipulated the price of
    natural gas by reporting false information to price indices
    published by trade publications and engaging in wash sales.
    See In re W. States Wholesale Nat. Gas Antitrust Litig.,

    A “wash trade” is “a prearranged pair of trades of the same good
    between the same parties, involving no economic risk and no net change
    in beneficial ownership. These trades expose the parties to no monetary
    risk and serve no legitimate business purpose.” Such trades were alleged
    to have “exaggerated market demand for natural gas and thus
    manipulate[d] natural gas prices.”
    3
    “Churning” is “a pattern of natural gas purchases and sales”
    wherein (a) the gas marketing companies “both bought and sold during
    the trading interval, so that the trades largely offset each other,”
    (b) “gross trading volume greatly exceeded net trading volume,” and
    (c) the companies “made a relatively large number of consecutive
    purchases and/or sales in a short amount of time, often being the only
    buyer and/or seller during the burst of transactions.” “Churning”
    allegedly enabled the companies to “artificially manipulate the day’s
    average price by initially buying (which raised the prices), and then
    selling (which brought prices back down).”

    were eventually consolidated into a multi-district litigation
    proceeding in the District of Nevada, In re W. States
    Wholesale Nat. Gas Antitrust Litig., MDL No. 1566 (the
    “MDL”); see also In re W. States, 715 F.3d at 727. The
    MDL includes the instant action.
    Plaintiffs (collectively known in the MDL below as the
    “Arandell Plaintiffs”) filed this action in Wisconsin state
    court on December 15, 2006, on behalf of a proposed class
    of “all industrial and commercial purchasers of natural gas”
    who purchased natural gas “for their own use or
    consumption . . . in Wisconsin” between January 1, 2000,
    and October 31, 2002 (the “Class Period”). The defendants
    are ten large natural gas companies, including certain of their
    subsidiaries and affiliates, who allegedly colluded to fix
    retail natural gas prices in Wisconsin. The action was
    removed on the basis of diversity jurisdiction to the Western
    District of Wisconsin on February 9, 2007. On June 29,
    2007, the case was transferred to the MDL in the District of
    Nevada.
    This appeal is from the district court’s grant of summary
    judgment to one defendant in the Arandell case, CenterPoint
    Energy Services, Inc. (“CES”). 4 CES sold natural gas and
    related services to commercial and industrial customers in
    Wisconsin during the Class Period. From January 1, 2000,
    to August 31, 2002 (33 of the 34 months in the Class Period),
    CES was a wholly owned subsidiary of Reliant Energy, Inc.
    4
    Like the parties’ briefs, we refer to CenterPoint Energy Services
    by its current name. However, CES was known as Retail Energy Retail,
    Inc. during the Class Period.

    (“Old Reliant”). 5 Within the Reliant family of companies,
    CES dealt primarily with Reliant Energy Services, Inc.
    (“RES” and together with Old Reliant and the other Reliant
    co-defendants collectively “Reliant”), a commonly owned
    affiliate during most of the Class Period.6 Reliant has
    admitted to engaging in wash trades during the Class Period
    and has reached settlements with several government
    agencies regarding its manipulative trading practices during
    that time.
    In this action, Plaintiffs alleged that certain Reliant
    entities—including CES, Old Reliant, and RES—conspired
    with other natural gas conglomerates to fix retail natural gas
    prices in Wisconsin. Plaintiffs further alleged that CES in
    particular sold natural gas in Wisconsin at prices that were
    artificially inflated as a result of the price-fixing conspiracy
    between Reliant and other, non-Reliant co-conspirators.
    Plaintiffs alleged two causes of action under Wisconsin’s
    5
    From January 1, 2000, to August 31, 2002, CES was a wholly
    owned subsidiary of Reliant Energy Resources Corp., which, in turn, was
    a wholly owned subsidiary of Old Reliant.
    6
    During the Class Period, Old Reliant was in the process of
    restructuring its business pursuant to a plan filed with the Texas Public
    Utility Commission as required by Texas law. From January 1, 2000, to
    January 1, 2001 (the first year of the Class Period), CES and RES were
    both wholly owned subsidiaries of RERC, which was itself wholly
    owned by Old Reliant. The first phase of the restructuring was
    completed on January 1, 2001 (one year into the Class Period). After
    January 1, 2001, Old Reliant owned 83% of RES (through a new
    company, Reliant Resources Inc.), while CES remained wholly owned
    (through RERC). Reliant completed the restructuring one month before
    the end of the Class Period. As of September 30, 2002, the restructuring
    of Old Reliant resulted in two independent, publicly traded companies:
    Reliant Resources, Inc. (“New Reliant”), which owned RES, and
    CenterPoint Energy, Inc., which owned CES.
    ARANDELL V. CENTERPOINT ENERGY SERVS.                  9
    antitrust statutes, seeking (1) a declaratory judgment that
    certain natural gas contracts made during the Class period
    are void under Wisconsin Statute § 133.14, and (2) treble
    damages for violations of Wisconsin Statute § 133.03, which
    provides that “[e]very contract, combination in the form of
    trust or otherwise, or conspiracy, in restraint of trade or
    commerce is illegal.”
    In the MDL, the district court granted CES’s motion for
    summary judgment against the Plaintiffs’ Third Amended
    Complaint (“TAC”). CES argued that it was entitled to
    summary judgment because it was “not alleged to have
    engaged in any anticompetitive activity or other wrongdoing
    in or directed to Wisconsin,” but rather it was alleged only
    to have been affiliated with RES and to have sold gas to
    Wisconsin consumers. The district court agreed that
    Plaintiffs had not raised a genuine issue of material fact
    sufficient to support a verdict or judgment under Wisconsin
    Statute § 133.03(1) because there was “no evidence” that
    CES knowingly “participated in a conspiracy or direct acts
    in restraint of trade.” In particular, the court ruled that there
    was no evidence that CES “knowingly” engaged in swaps
    “in conspiracy with RES” for “the purpose of increasing the
    price of natural gas,” or that CES “knew that RES or others
    were engaged in such behavior.”
    On appeal, Plaintiffs summarized their case against CES
    as follows:
    CES (formerly a Reliant company) made an
    essential contribution to the Reliant
    companies’ coordinated price-fixing efforts.
    Each Reliant company played a necessary
    role. The Reliant trading company (RES)
    inflated retail natural gas prices through
    manipulative trading and false reporting of
    10      ARANDELL V. CENTERPOINT ENERGY SERVS.
    sales data to publishers of benchmark price
    indices. RES then sold gas at inflated prices
    to CES, the Reliant sales subsidiary. CES
    resold the overpriced gas to Wisconsin
    businesses, collected millions of dollars in
    overcharges at the expense of the class
    members, and funneled the revenues from
    these sales to the Reliant parent. The officers
    and directors of the Reliant parent
    orchestrated this scheme, directing RES to
    manipulate retail prices and instructing CES
    to send its illegal profits to the Reliant parent.
    Plaintiffs argue the district court erred in: (1) determining
    that Plaintiffs needed to produce evidence that CES
    intentionally conspired with RES to inflate gas prices in
    order to raise a triable issue, (2) failing to consider record
    evidence that CES purposely or knowingly furthered the
    alleged inter-enterprise conspiracy by selling gas at rigged
    prices and channeling the proceeds to Old Reliant, and
    (3) granting summary judgment without considering the
    Plaintiffs’ Rule 56(d) motion for additional discovery.
    II. DISCUSSION
    We review the district court’s grant of summary
    judgment de novo. Kaiser Cement Corp. v. Fischbach &
    Moore, Inc., 
    793 F.2d 1100
    , 1103 (9th Cir. 1986). “[T]he
    court’s ultimate inquiry is to determine whether the ‘specific
    facts’ set forth by the nonmoving party, coupled with
    undisputed background or contextual facts, are such that a
    rational or reasonable jury might return a verdict in its favor
    based on that evidence.” T.W. Elec. Serv., Inc. v. Pac. Elec.
    Contractors Ass’n, 
    809 F.2d 626
    , 631 (9th Cir. 1987). For
    purposes of summary judgment, CES does not contest the
    ARANDELL V. CENTERPOINT ENERGY SERVS.                11
    substance of Plaintiffs’ evidence that one or more of the
    other Reliant entities successfully conspired with non-
    Reliant entities to manipulate gas prices during the Class
    Period, or that CES bought gas from RES and sold it to
    consumers in Wisconsin during the Class Period. Therefore,
    the question before the court is whether Plaintiffs submitted
    sufficient evidence to raise triable issues as to (1) whether
    CES had the requisite intent and purpose to restrain trade,
    and (2) whether CES did in fact act to further the alleged
    conspiracy. We address each in turn.
    A. Anticompetitive Intent
    Wisconsin courts’ interpretation of Wisconsin Statute
    § 133.03 “is controlled by federal court decisions under the
    Sherman Act.” Ford Motor Co. v. Lyons, 
    405 N.W.2d 354
    ,
    367 (Wis. Ct. App. 1987). Section 1 of the Sherman Act
    provides that “[e]very contract, combination . . . , or
    conspiracy, in restraint of trade or commerce among the
    several States, or with foreign nations, is declared to be
    illegal.” 
    15 U.S.C. § 1
    . A defendant may be held “liable
    under § 1 of the Sherman Act if that person . . . [acted] either
    with the knowledge that the . . . [action] would have
    unreasonable anticompetitive effects or with the purpose of
    producing those effects.” United States v. Bailey, 
    444 U.S. 394
    , 404–05 (1980). Plaintiffs argue that the evidence
    submitted below established that CES purposely participated
    in the price-fixing scheme because, as a wholly owned
    subsidiary of Reliant during the Class Period, CES is deemed
    to have shared the intent of the commonly owned Reliant
    conspirators. Plaintiffs also argue that they submitted
    evidence showing overlap among the directors and managers
    of CES, on one hand, and the alleged Reliant conspirators,
    on the other—creating a genuine issue of material fact as to
    12      ARANDELL V. CENTERPOINT ENERGY SERVS.
    whether CES knowingly participated in the price-fixing
    scheme.
    1. Purpose
    Plaintiffs argue that, contrary to the district court’s
    decision, Wisconsin antitrust law did not require them to
    prove “that CES knowingly engaged ‘in [a] conspiracy with
    RES . . . with the purpose of increasing the price of natural
    gas” to create a triable issue as to CES’s liability. According
    to Plaintiffs, the “Copperweld doctrine”—named for the
    U.S. Supreme Court case Copperweld Corp. v.
    Independence Tube Corp., 
    467 U.S. 752
     (1984)—
    establishes that “the Reliant Defendants that participated in
    price-fixing (CES, RES, and REI) acted as a single
    enterprise, with a shared intent.” Copperweld—like all
    federal antitrust precedents—is applicable to claims under
    Wisconsin Statute § 133.03. Lyons, 
    405 N.W.2d at 367
    (adopting and following Copperweld as a matter of
    Wisconsin law).
    In Copperweld, the plaintiff alleged that Copperweld and
    its wholly owned subsidiary, Regal Tube Co. (“Regal”),
    conspired to prevent a former Regal employee from
    competing with Regal by threatening to sue prospective
    customers and financers of the former employee’s new
    business. 
    Id.
     at 755–58. A jury found that Copperweld and
    Regal violated Section 1 of the Sherman Act, and the
    Seventh Circuit affirmed. Id. at 758. The Supreme Court
    reversed. Id. at 777. Rejecting “the so-called ‘intra-
    enterprise conspiracy’ doctrine,” which permitted Section 1
    liability between commonly owned companies, id. at 759,
    the Court held that “the coordinated activity of a parent and
    its wholly owned subsidiary must be viewed as that of a
    single enterprise for purposes of § 1” because “[a] parent and
    its wholly owned subsidiary have a complete unity of
    ARANDELL V. CENTERPOINT ENERGY SERVS.                      13
    interest,” id. at 771. Therefore, a parent company and its
    wholly owned subsidiary “are incapable of conspiring with
    each other for purposes of § 1 of the Sherman Act.” Id. at
    777. As relevant here, the Copperweld doctrine establishes
    that “[w]here there is substantial common ownership, . . .
    individual firms function as an economic unit and are
    generally treated as a single entity.” Freeman v. San Diego
    Ass’n of Realtors, 
    322 F.3d 1133
    , 1147–48 (9th Cir. 2003).
    The district court was correct that, for antitrust purposes,
    CES did not conspire with RES; under Copperweld, it was
    incapable of doing so as a matter of law. But Plaintiffs’
    theory of the case is that CES was part of a “single entity”—
    including both RES (a commonly owned company) and Old
    Reliant (its parent)—which “intentionally colluded with
    other, non-Reliant conspirators to manipulate natural gas
    prices and profit from this manipulation.” 7 Therefore, they
    argue, the district court should have found that as a matter
    of law it was “not possible for CES to have a different reason
    than [Old Reliant] and RES for participating in these
    efforts.”
    Although the Plaintiffs’ application of the principles laid
    out in Copperweld is novel, we must agree. The Supreme
    Court stated in Copperweld that a parent and its wholly
    owned subsidiary “always have a ‘unity of purpose or a
    common design.’ They share a common purpose whether or
    not the parent keeps a tight rein over the subsidiary.”
    Copperweld, 
    467 U.S. at 771
     (emphasis added); see also
    Freeman, 
    322 F.3d at
    1147–48 (“Where there is substantial
    7
    For purposes of summary judgment, CES does not contest the
    substance of the evidence that Reliant successfully conspired with the
    other (non-Reliant) defendants and co-conspirators to manipulate retail
    gas prices.
    14     ARANDELL V. CENTERPOINT ENERGY SERVS.
    common ownership, . . . individual firms function as an
    economic unit and are generally treated as a single entity.”).
    The Supreme Court could have hardly made this point more
    explicit:
    The coordinated activity of a parent and its
    wholly owned subsidiary must be viewed as
    that of a single enterprise for purposes of § 1
    of the Sherman Act. A parent and its wholly
    owned subsidiary have a complete unity of
    interest. Their objectives are common, not
    disparate; their general corporate actions are
    guided or determined not by two separate
    corporate consciousnesses, but one. They are
    not unlike a multiple team of horses drawing
    a vehicle under the control of a single driver.
    With or without a formal “agreement,” the
    subsidiary acts for the benefit of the parent,
    its sole shareholder.
    . . . [I]n reality a parent and a wholly owned
    subsidiary always have a “unity of purpose or
    a common design.” They share a common
    purpose whether or not the parent keeps a
    tight rein over the subsidiary; the parent may
    assert full control at any moment if the
    subsidiary fails to act in the parent’s best
    interests.
    Copperweld, 
    467 U.S. at
    771–72 (emphases added). This
    premise led the Supreme Court to conclude that a parent
    cannot conspire with its subsidiary, but it also leads
    inescapably to the corollary conclusion that, for antitrust
    purposes, it is legally impossible for firms within a single
    “economic unit” to act together in furtherance of the same
    ARANDELL V. CENTERPOINT ENERGY SERVS.                      15
    price-fixing scheme for independent and distinct purposes.
    True, Copperweld decided only that a parent and its wholly
    owned subsidiary could not conspire with each other for
    purposes of Section 1 of the Sherman Act, but “[a]s a general
    rule, the principle of stare decisis directs us to adhere not
    only to the holdings of our prior cases, but also to their
    explications of the governing rules of law.” Miller v.
    Gammie, 
    335 F.3d 889
    , 900 (9th Cir. 2003) (quoting Cty. of
    Allegheny v. ACLU Greater Pittsburgh Chapter, 
    492 U.S. 573
    , 668 (1989) (Kennedy, J., concurring in part and
    dissenting in part)).        From the Supreme Court’s
    “explications” in Copperweld, the corollary proposed by
    Plaintiffs necessarily follows: If “a parent and a wholly
    owned subsidiary always have a ‘unity of purpose’” and act
    as a “single enterprise” whenever they engage in
    “coordinated activity,” then a subsidiary such as CES as a
    matter of law cannot innocently advance an anticompetitive
    scheme (here, by selling gas at prices rigged by Reliant and
    distributing the profits to Reliant) for a legitimate business
    purpose, while its parent and sister companies purposely
    advance the very same scheme (here, by rigging the prices
    upstream) for an illegal, anticompetitive purpose.
    The Tenth Circuit, so far the only Court of Appeals
    squarely to consider such an application of Copperweld,
    recently reached the same conclusion in Lenox MacLaren
    Surgical Corp. v. Medtronic, Inc., 
    847 F.3d 1221
     (10th Cir.
    2017). There, the district court had granted summary
    judgment to the defendant on claims under Section 2 of the
    Sherman Act. 8 
    Id.
     at 1229–30. The plaintiff in Lenox argued
    8
    Lenox dealt with a claim under Section 2 of the Sherman Act.
    847 F.3d at 1229. Section 2 provides that “[e]very person who shall
    monopolize, or attempt to monopolize, or combine or conspire with any
    other person or persons, to monopolize any part of the trade or commerce
    16       ARANDELL V. CENTERPOINT ENERGY SERVS.
    that “its burden of establishing any individual defendant’s
    liability required showing only that the defendant’s conduct
    played a ‘role’ in the overall anticompetitive scheme
    perpetrated by the enterprise as a whole.” Id. at 1230. The
    Tenth Circuit panel agreed. It held that, under Copperweld,
    the plaintiff did not need to prove that “‘specific Defendants’
    independently satisfied each necessary element of the
    claims,” because “in a single-enterprise situation, it is the
    affiliated corporations’ collective conduct—i.e., the conduct
    of the enterprise they jointly compose—that matters; it is the
    enterprise which must be shown to satisfy the elements of a
    [Section 2] claim.” Id. at 1236 (emphasis in original).
    Therefore, the Tenth Circuit panel concluded that the
    plaintiff “advanced a viable, if somewhat unusual, antitrust
    theory.” Id. at 1230. Ultimately, the court granted summary
    judgment to the defendants on the basis of claim preclusion.
    Id. at 1239. One of the companies in the “single entity”
    identified by the court had previously won a final judgment
    on the merits on claims based on the same underlying events.
    See id. at 1239–40. Applying the plaintiffs’ Copperweld
    theory, claims against other defendants in the “single entity”
    were thus precluded. Id. at 1239.
    Defendants cannot have the Copperweld doctrine both
    ways. It would be inconsistent to insist both (1) that two
    affiliates are incapable of conspiring with each other for
    purposes of Section 1 of the Sherman Act because they
    “always” share a “unity of purpose,” and (2) that one affiliate
    may escape liability for its own conduct—conduct necessary
    to accomplish the illegal goals of the scheme—by
    among the several States, or with foreign nations, shall be deemed guilty
    of a felony.” 
    15 U.S.C. § 2
    . However, the Tenth Circuit panel based its
    holding on Copperweld, a Section 1 case, which it held to apply equally
    to Section 2 cases. Id. at 1234.
    ARANDELL V. CENTERPOINT ENERGY SERVS.               17
    disavowing the anticompetitive intent of the other, even
    where the two acted together. See id. at 1236 (finding that
    Copperweld “forecloses” a result that would allow
    sophisticated companies to evade Section 2 liability by
    spreading anticompetitive schemes over multiple affiliates).
    In sum, Copperweld supports the following rule: A wholly
    owned subsidiary that engages in coordinated activity in
    furtherance of the anticompetitive scheme of its parent
    and/or commonly owned affiliates is deemed to engage in
    such coordinated activity with the purposes of the single
    “economic unit” of which it is a part.
    Here, Plaintiffs submitted evidence that the Reliant
    “economic unit” had an anticompetitive purpose during the
    Class Period. Such anticompetitive “purpose” can sustain
    liability under the Sherman Act with or without an additional
    finding of “knowledge,” Bailey, 
    444 U.S. at
    404–05; United
    States v. U.S. Gypsum Co., 
    438 U.S. 422
    , 446 (1978) (stating
    that requiring proof of both knowledge and purpose for
    liability under Section 1 of the Sherman Act would be
    “unnecessarily cumulative”). Therefore, because the Reliant
    enterprise’s alleged illegal purposes are imputed to CES’s
    coordinated activities, the district court erred in granting
    summary judgment on the basis that Plaintiffs failed to raise
    a triable issue of CES’s intent.
    2. Knowledge
    Furthermore, Plaintiffs’ evidence was sufficient to raise
    a triable issue of whether CES knowingly acted to further the
    alleged price-fixing scheme. Plaintiffs submitted evidence
    of substantial overlap, during the Class Period, between the
    directors and officers of CES, on one hand, and the directors
    and officers of Old Reliant, RES, and other commonly
    owned Reliant entities. For example, it is undisputed that
    (1) Marc Kilbride was the Treasurer for CES from 2000 to
    18     ARANDELL V. CENTERPOINT ENERGY SERVS.
    2002, and also the Treasurer for RES in 2000 and for RERC
    from 2000 to 2003, (2) David M. McClanahan served as the
    Chairman of CES’s board of directors in 2002, after having
    served as the President and sole director of RERC from 2001
    to 2002, and (3) Hugh Rice Kelly was the Corporate
    Secretary for CES in 2000, General Counsel and Corporate
    Secretary to Old Reliant from 2000 to 2001, and then the
    Corporate Secretary for RES in 2002. Plaintiffs’ evidence
    shows a network of fast-revolving doors connecting the
    boardrooms and executive offices of CES and the other
    Reliant companies.
    Any knowledge of the alleged price-fixing scheme that
    CES’s directors and officers acquired while concurrently
    acting as directors or officers of the other Reliant companies
    is imputable to CES as a matter of Wisconsin law. Suburban
    Motors of Grafton, Inc. v. Forester, 
    396 N.W.2d 351
    , 355
    (Wis. Ct. App. 1986) (“The general rule is well established
    that a corporation is charged with constructive knowledge,
    regardless of its actual knowledge, of all material facts of
    which its officer or agent receives notice or acquires
    knowledge while acting in the course of his employment
    within the scope of his authority, even though the officer or
    agent does not in fact communicate his knowledge to the
    corporation.” (quoting 3 W. Fletcher, Cyclopedia of the Law
    of Private Corporations § 790 (rev. perm. ed. 1975)
    (footnotes omitted and alteration in original))). Plaintiffs
    submitted evidence that Reliant traders engaged in
    manipulative trade practices at the direction of Reliant
    management. Plaintiffs also submitted evidence that such
    manipulative practices were a matter of common knowledge
    within Reliant. Drawing all rational inferences in favor of
    Plaintiffs, these facts permit a reasonable finding that CES’s
    directors or officers acquired knowledge of Reliant’s
    manipulative trading practices while concurrently serving as
    ARANDELL V. CENTERPOINT ENERGY SERVS.                       19
    directors or officers of other Reliant companies. T.W. Elec.,
    
    809 F.2d at 631
     (holding that “[i]nferences must . . . be
    drawn in the light most favorable to the nonmoving party”
    so long as “it is ‘rational’ or ‘reasonable’ and otherwise
    permissible under the governing substantive law”). Because
    such knowledge would be imputed to CES as a matter of
    Wisconsin law, Plaintiffs raised a genuine issue of material
    fact as to CES’s knowledge of the alleged price-fixing
    scheme.
    B. Anticompetitive Acts
    We next consider whether there was a genuine issue of
    material fact as to whether CES acted to further the alleged
    price-fixing conspiracy. As Plaintiffs admit, Copperweld
    speaks only of a “unity of purpose,” 
    467 U.S. at 771
    (emphasis added). It does not supply a theory of unbounded
    vicarious liability for the acts of legally distinct entities.
    Rather, Copperweld states that commonly-owned-but-
    legally-distinct entities are considered a “single entity” for
    antitrust purposes where they engage in “coordinated
    activity.” 9 See 
    467 U.S. at 771
     (“The coordinated activity
    of a parent and its wholly owned subsidiary must be viewed
    as that of a single enterprise for purposes of § 1 of the
    Sherman Act.” (emphasis added)). Thus, a subsidiary shares
    the purposes and intentions of the parent when it acts in
    9
    This distinction provides a bright-line limit on an antitrust
    plaintiff’s recovery from a particular defendant. While a “veil-piercing,
    alter ego, or respondeat superior theory” might render a defendant
    separately and individually liable for any conduct of its corporate
    affiliates, Plaintiffs’ theory seeks to hold CES liable only for its own
    alleged anticompetitive acts. See Lenox, 847 F.3d at 1237. Therefore,
    any recovery from an affiliate under Plaintiffs’ Copperweld corollary
    would be limited to damages caused by anticompetitive conduct
    attributable to that affiliate.
    20       ARANDELL V. CENTERPOINT ENERGY SERVS.
    coordination with the parent, but Copperweld does not
    support holding a subsidiary liable for the parent’s
    independent conduct. See Lenox, 847 F.3d at 1237
    (“[A]lthough we agree that [the plaintiff] was entitled to
    pursue its § 2 claims against Defendants as a single
    enterprise, and to prove those claims based on the actions of
    the enterprise as a whole, [the plaintiff] was still required to
    come forward with evidence that each defendant
    independently participated in the enterprise’s scheme, to
    justify holding that defendant liable as part of the
    enterprise.”). As with any antitrust defendant, Plaintiffs
    must put forth evidence that CES engaged in anticompetitive
    conduct. 10
    To be liable on a Section 1 claim, a defendant must have
    conspired (or agreed or combined, etc.) to restrain trade. “It
    is not necessary to find an express agreement, either oral or
    written, in order to find a conspiracy, but it is sufficient that
    10
    The cases cited by CES merely apply this distinction, and thus
    they are not contrary to Plaintiffs’ “single entity” theory. See In re Ins.
    Brokerage Antitrust Litig., 
    618 F.3d 300
    , 341 n.44 (3d Cir. 2010) (noting
    the defendant subsidiaries were not alleged to have actually participated
    in the alleged bid-rigging scheme); Mitchael v. Intracorp, Inc., 
    179 F.3d 847
    , 857 (10th Cir. 1999) (rejecting “single enterprise” theory “[i]n the
    absence of any specific evidence of coordinated activity” and
    distinguished on this basis in Lenox, 847 F.3d at 1234); Acuity Optical
    Labs., LLC v. Davis Vision, Inc., No. 14-cv-03231, 
    2016 WL 4467883
    ,
    at *9 (C.D. Ill. Aug. 23, 2016) (finding no “actual evidence” of
    “coordinated activity”); Vollrath Co. v. Sammi Corp., No. CV 85-820
    MRP,
    1989 WL 201632
    , at *20–21 (C.D. Cal. Dec. 20, 1989) (finding no
    evidence of an inter-enterprise conspiracy and thus no actionable
    conspiracy under Copperweld); cf. Am. Needle, Inc. v. Nat’l Football
    League, 
    560 U.S. 183
    , 195–96 (2010) (holding that separately owned
    NFL teams were not a “single entity” under Copperweld). Cases
    addressing veil-piercing, alter-ego, and respondeat-superior theories are
    likewise inapposite.
    ARANDELL V. CENTERPOINT ENERGY SERVS.                21
    a concert of action be contemplated and that defendants
    conform to the arrangement.” Esco Corp. v. United States,
    
    340 F.2d 1000
    , 1008 (9th Cir. 1965). “[A]ny conformance
    to an agreed or contemplated pattern of conduct will warrant
    an inference of conspiracy.” 
    Id.
     Therefore, CES’s alleged
    contributions to the conspiracy (selling gas to Wisconsin
    consumers at the inflated prices and disbursing the profits to
    Reliant), would be adequate circumstantial evidence of
    conspiracy, if proved, to permit a finding of liability.
    This conclusion comports with ordinary conspiracy
    principles.      “While particularly true of price-fixing
    conspiracies, it is well recognized law that any conspiracy
    can ordinarily only be proved by inferences drawn from
    relevant and competent circumstantial evidence, including
    the conduct of the defendants charged.” 
    Id. at 1007
    . Thus,
    even in the criminal context, the government “need show
    neither direct contact nor explicit agreement among all of the
    alleged conspirators.” United States v. Reese, 
    775 F.2d 1066
    , 1071 (9th Cir. 1985). Nor must the government show
    “that each defendant or all defendants must have participated
    in each act or transaction.” Esco, 
    340 F.2d at 1006
    .
    Involvement “in but two of ten allegedly conspirational [sic]
    situations does not absolve [a defendant] from participation
    in the entire conspiracy if its involvement in the two was
    unlawful and knowingly and purposely performed.” 
    Id. at 1008
    . Nor can a single defendant “join a continuing
    conspiracy long after others have commenced it, or partially
    carried it out, and thereby claim immunity either for his
    actions, or for those of others taking place before or after his
    active participation, as long as he remains an active
    participant.” 
    Id. at 1006
     (emphasis added and citation
    omitted). In sum, CES may be held liable for its own acts in
    purposeful and knowing furtherance of the alleged inter-
    enterprise price-fixing conspiracy, if proven.
    22        ARANDELL V. CENTERPOINT ENERGY SERVS.
    The remaining question is whether Plaintiffs submitted
    sufficient evidence to raise a genuine issue as to whether
    CES in fact participated in coordinated activity in
    furtherance of the alleged inter-enterprise price-fixing
    conspiracy. 11 Plaintiffs submitted evidence that, during the
    Class Period, CES sold gas at rigged prices and then
    distributed the proceeds up to its parent’s coffers. CES does
    not deny that it sold gas it purchased from RES to consumers
    in Wisconsin.12 Plaintiffs also submitted evidence that the
    profits from CES’s natural gas sales “rolled up” to Reliant
    and its shareholders, and that Reliant would report those
    distributions as revenues in its consolidated financial
    reports.
    This evidence suffices to create a triable issue of liability
    under the Sherman Act, and thus it suffices under Wisconsin
    Statute § 133.03(1) as well. Crediting Plaintiffs’ evidence,
    CES’s role was essential to securing the benefit of the other
    Reliant defendants’ price-fixing (at least in Wisconsin), and
    CES’s acts were the immediate cause of Plaintiffs’ injuries.
    T.W. Elec., 
    809 F.2d at 631
     (“If the nonmoving party
    produces direct evidence of a material fact, the court may not
    assess the credibility of this evidence nor weigh against it
    any conflicting evidence presented by the moving party.”).
    In selling gas at rigged prices and distributing the inflated
    11
    Again, for purposes of summary judgment, CES does not contest
    the substance of Plaintiffs’ evidence that one or more Reliant companies
    successfully conspired with non-Reliant defendants and co-conspirators
    to manipulate the prices of gas sold by CES during the Class Period. See
    FERC Final Report at ES-5 (describing churning by Reliant in 2000 and
    2001).
    12
    The parties dispute how much gas CES sold in Wisconsin, how
    much money CES received for that gas, and how much of that gas came
    from RES. These are issues for the trier of fact.
    ARANDELL V. CENTERPOINT ENERGY SERVS.               23
    profits to its parent, CES helped to carry out the inter-
    enterprise conspiracy with the other gas companies (just as
    Reliant allegedly carried out the conspiracy by reporting
    sham sales to the trade publications). CES’s role was not
    only helpful to the conspirators, it was crucial: Until CES
    sold the gas to consumers, the rigged and inflated prices
    were not passed on to buyers outside of the Reliant economic
    unit and there was no gain to the Reliant enterprise. Cf.
    United States v. Socony-Vacuum Oil Co., 
    310 U.S. 150
    , 253
    (1940) (noting that an alleged antitrust conspiracy “would
    fail” if the conspirators could not charge higher prices to the
    “jobbers and consumers”). “[T]he conspiracy contemplated
    and embraced, at least by clear implication, sales to . . .
    consumers . . . at the enhanced prices. The making of those
    sales supplied part of the ‘continuous cooperation’ necessary
    to keep the conspiracy alive.” 
    Id.
    CES argues that “sales to Wisconsin customers were
    unnecessary for RES to profit from the alleged conspiracy”
    because “RES would accrue any purported benefit of
    increased prices once RES’s sale occurred—whether to CES
    or any other customer.” But this argument ignores
    Copperweld’s instruction to treat RES and CES as part of a
    “single entity.” CES’s and RES’s respective balance sheets
    may have changed when CES bought gas from RES, but the
    Reliant enterprise did not benefit until Reliant gas was sold
    to someone outside the enterprise. Reliant could not profit
    by moving cash from its right pocket to its left.
    CES’s critical contributions to the conspiracy, if proved,
    would permit a rational factfinder to find that CES joined the
    conspiracy. Because CES is deemed to have engaged in this
    coordinated activity with the alleged illegal purpose of its
    affiliates, Plaintiffs have raised a triable issue of CES’s
    liability under Wisconsin antitrust law. Accordingly, the

    district court’s grant of summary judgment is reversed.
    Because we reverse the district court’s grant of summary
