    NIEMEYER, Circuit Judge:
    NTE Carolinas II, LLC (“NTE” 1), a power company based in St. Augustine, Florida,
    sued Duke Energy Corporation (“Duke” 2), a power company based in Charlotte, North
    Carolina, alleging that Duke had monopoly power in the wholesale power market in the
    Carolinas and willfully maintained that power through anticompetitive conduct to exclude
    NTE from the market, in violation of § 2 of the Sherman Act. See 
    15 U.S.C. §§ 2
    , 15. In
    particular, NTE presented evidence in the district court that Duke devised a plan to ensure
    that NTE, its only serious competitor, would not have the opportunity to compete for the
    business of Fayetteville, North Carolina, the only major wholesale customer whose long-
    term contract with Duke was expiring soon enough to allow NTE to compete for its
    business.
    The district court granted Duke’s motion for summary judgment, in which Duke
    argued that the conduct that NTE imputed to Duke constituted legitimate competition in
    seeking to retain Fayetteville’s business and that none of the actions on which NTE relied
    was unlawful. While the court concluded that there was a question of fact on whether Duke
    had monopoly power, it also concluded as a matter of law that Duke did not engage in
    anticompetitive conduct but rather legitimate competition to retain Fayetteville’s business.
    NTE will be used as shorthand to refer collectively to NTE Carolinas II, LLC;

    The record in this case is large, and it contains much evidence related to Duke’s
    conduct in response to NTE’s competitive efforts. While we recognize that much of
    Duke’s conduct can be understood to be legitimate competitive conduct, as well explained
    by very able counsel, we also have found much from which a jury could conclude that
    Duke’s actions were illegitimate anticompetitive conduct that violated § 2 of the Sherman
    Act, also as well explained by very able counsel. Because genuine disputes of material
    fact exist, we vacate the district court’s summary judgment and remand for further
    proceedings.
    We also order that, on remand, the case be assigned to a different judge. In an act
    of caution, the district judge in this case initially recused himself because of the appearance
    of one of his former law partners on behalf of Duke. But he was reassigned the case a
    couple of years later after the “conflict” abated, and he then declined to recuse himself on
    NTE’s motion, determining that his earlier recusal had not been necessary. We conclude,
    as most courts have, that once a judge recuses himself from a case, he should remain
    recused from that case, even though his recusal may not have originally been required.
    I
    After Duke filed an answer to NTE’s operative antitrust complaint, the parties
    engaged in extensive discovery, creating a substantial record, which included detailed and
    complex expert witness reports. Duke then filed a motion for summary judgment based on
    that record. While the district court concluded that genuine questions of material fact
    remained on whether Duke had monopoly power, it concluded that NTE failed to show
    4
    USCA4 Appeal: 22-2168       Doc: 93         Filed: 08/05/2024      Pg: 5 of 54
    that Duke had engaged in “improper exclusionary conduct harming competition.” Duke
    Energy Carolinas, LLC v. NTE Carolinas II, LLC, 
    608 F. Supp. 3d 298
    , 317 (W.D.N.C.
    2022). Identifying five distinct courses of conduct claimed by NTE to have been part of
    Duke’s anticompetitive scheme, the district court addressed each course independently,
    found that each was not unlawful by itself, and concluded that “[a]dding up several
    instances of lawful conduct [could not] total unlawful conduct.” 
    Id. at 319
    ; see also 
    id.
     at
    319–28. The court accordingly granted summary judgment to Duke.
    Because one issue raised is whether the record reveals genuine issues of material
    fact, we find it appropriate to recite the record in some detail.
    A
    The summary judgment record shows the following:
    NTE, as an independent power producer (“IPP”), generates power at power plants,
    but it does not own transmission lines and therefore cannot, with its own resources, transmit
    the energy it produces to wholesale customers. Thus, NTE must rely on the transmission
    networks owned by other energy companies to transmit electricity over power lines to
    its wholesale customers, typically municipalities. J.A. 4455; FERC, Energy Primer:
    A Handbook of Energy Market Basics 47 (2020). To facilitate such access, the Federal
    Energy Regulatory Commission (“FERC”) requires utilities to share their transmission
    networks with competitors. See generally Promoting Wholesale Competition Through
    Open Access Non-Discriminatory Transmission Services by Public Utilities, 
    61 Fed. Reg. 21540
     (May 10, 1996).
    5
    USCA4 Appeal: 22-2168      Doc: 93        Filed: 08/05/2024     Pg: 6 of 54
    In 2014, NTE began construction of a new combined-cycle natural gas facility in
    Kings Mountain, North Carolina. See J.A. 4616. To transmit electricity in the Carolinas,
    however, it needed to use the transmission lines of Duke, a longtime monopolist holding
    more than 90% of the wholesale power market in the region. J.A. 4481. Duke is a
    vertically integrated power company, meaning that it owns both power plants and
    transmission lines and serves both wholesale and retail customers. In accordance with
    FERC regulations requiring interconnection, Duke and NTE entered into a standard
    interconnection agreement, with Duke providing NTE access to its transmission network
    so that NTE could sell power from its Kings Mountain plant. While NTE thus entered
    Duke’s service area, Duke at first had little concern about its presence as a competitor,
    inasmuch as NTE’s Kings Mountain plant was a relatively small generator. Duke’s Vice
    President of Wholesale Power Sales remarked at the time that he “[thought] it [was] very
    doubtful that the threat [of Duke customers switching to NTE] [was] real.” J.A. 4830.
    Duke’s view of NTE changed over the following year, however, as Duke began to
    realize that NTE was successfully attracting Duke customers. See J.A. 5047 (Duke email
    stating that NTE winning Winterville was a “total surprise”). In October 2014, Duke
    executives asked their subordinates to keep them briefed on NTE’s development plans.
    J.A. 4832–33. In January 2015, Duke’s internal briefing reports showed that “[s]tand-alone
    combined cycle plants” like NTE’s “offer less expensive energy than Duke Energy system
    average rates for the foreseeable future, along with lower capacity prices.” J.A. 4881. In
    short, the combined-cycle plants that NTE was in the business of building were more cost-
    6
    USCA4 Appeal: 22-2168      Doc: 93         Filed: 08/05/2024     Pg: 7 of 54
    efficient than Duke’s own plants. See J.A. 4471–72. Duke then recognized that it
    “[couldn’t] chase the price competition and earn a reasonable return.” J.A. 4888.
    When NTE opened its Kings Mountain plant, Duke customers, too, took note of
    NTE’s new offerings. For example, in October 2015, a representative of a wholesale
    customer informed Duke that it was signing a Letter of Intent to buy electricity from NTE
    due to the savings that NTE offered, explaining:
    The issue with my towns is cost. We are in an area of the state where wages
    have stagnated and making ends meet is incredibly difficult for many folks.
    Duke’s offer, over the long term, was simply uneconomic.
    J.A. 5060. Eventually, Duke lost a total of nine of its customers to NTE selling electricity
    from its Kings Mountain plant. J.A. 4618. Yet, during that same time, it lost only one
    customer to a competitor other than NTE. See J.A. 4659.
    Despite NTE’s cleaner, more efficient power generators, Duke recognized that it
    had an advantage by reason of its long-term wholesale power supply contracts with its
    customers, which spanned 20 years and required several years’ notice of termination. See,
    e.g., J.A. 2545 (10-year notice period); J.A. 5235 (7-year notice period). These long-term
    contracts, which were common in the Southeast energy markets, decreased the risk that a
    Duke wholesale customer would switch to a new entrant provider of electricity like NTE.
    As a consequence, such contracts limited opportunities for new entrants such as NTE to
    compete for customers and thus to gain economies of scale. But Duke identified one
    contract that was set to expire soon enough for Duke to worry about losing a major
    customer’s business to NTE — the City of Fayetteville, which provided a peak demand
    load for electricity of approximately 500 MW. See J.A. 2847, 5086.
    7
    USCA4 Appeal: 22-2168      Doc: 93         Filed: 08/05/2024     Pg: 8 of 54
    Fayetteville had been a Duke customer for more than 100 years, and, at the time that
    NTE began its attempt to win Fayetteville’s business, Fayetteville and Duke were operating
    under a 20-year agreement that they had entered into in 2012 (“2012 Power Supply
    Agreement”). J.A. 4453, 6719. Under the 2012 Power Supply Agreement, Fayetteville
    agreed to buy power from Duke until June 30, 2032. But in the Agreement, Fayetteville
    retained the right to terminate the Agreement as of July 1, 2024, upon notice to Duke given
    by June 30, 2017 — a deadline that Duke extended to 2019 and later to 2020. J.A. 906–
    07, 2845, 3463. Duke not only sold Fayetteville electrical power, but, under a separate
    contract, it also purchased excess power from Fayetteville that was produced at
    Fayetteville’s Butler Warner plant. J.A. 2848. That plant was, however, very inefficient,
    made up of eight gas or oil combustion turbine generating units and one combined-cycle
    steam turbine unit. See J.A. 3683, 4942. In theory, Duke could sell the excess power
    generated at the Butler Warner plant to other customers. J.A. 1188; see also Response Br.
    at 9 (“Duke . . . bought excess power produced by Fayetteville’s power plant, which Duke
    could potentially sell to other customers”).
    In 2016, in light of NTE’s success with its King Mountain plant, Duke’s internal
    reports observed that “[b]ut for NTE customers,” Duke’s “portfolio [was] stable.” J.A.
    5086. Duke’s internal reports additionally projected that Duke’s rates would remain much
    higher than NTE’s through at least 2025, J.A. 5071, and that Duke’s “[c]ompetitive
    disadvantage [was] not going away soon,” J.A. 5086. NTE’s competitive advantage
    prompted Duke to recognize that Fayetteville, which had been providing Duke with $100
    million in annual net revenue, was its “[l]argest customer risk.” J.A. 5086. And in the
    8
    USCA4 Appeal: 22-2168      Doc: 93         Filed: 08/05/2024     Pg: 9 of 54
    months thereafter, Duke continued to report internally that NTE was its “biggest threat,”
    J.A. 4700, listing Duke’s relative inefficiency as a major factor for why Duke was, in its
    words, “not competitive,” J.A. 7273.
    NTE did indeed then have plans to build additional power plants in the Carolinas.
    But key to its plans for expansion was the rare opportunity — because of the terms of
    Fayetteville’s agreement with Duke — to compete for Fayetteville’s business. Thus, in
    2016, NTE announced its plan to build a second plant, the Reidsville Energy Center, which
    could serve Fayetteville. That plant would have a capacity of approximately 475 MW and
    would be a natural gas combined-cycle electric generation plant. J.A. 4466. To bring the
    Reidsville plant online, however, NTE needed to attract not only wholesale customers who
    were not already locked into long contracts, but especially a large wholesale customer such
    as Fayetteville.
    Because NTE was an IPP, it also needed to enter into an interconnection agreement
    with Duke to have access to Duke’s transmission lines for its Reidsville plant. So, in
    November 2017, again in accordance with FERC regulations, NTE and Duke entered into
    a standard interconnection agreement for the Reidsville plant (“the Reidsville
    Interconnection Agreement”). See J.A. 418–504; see also Standardization of Generator
    Interconnection Agreements and Procedures, Order No. 2003, 
    104 FERC ¶ 61,103
     (2003).
    Under this pro forma interconnection agreement, NTE agreed to pay Duke $58,917,362 to
    build the interconnection infrastructure for the Reidsville plant, and once the lines were
    built, Duke would own those transmission lines and charge NTE to use them. J.A. 465,
    491. The contract required NTE to make “security payments” — payments made in
    9
    USCA4 Appeal: 22-2168      Doc: 93         Filed: 08/05/2024     Pg: 10 of 54
    advance of incurred costs — for Duke’s construction work on a schedule fixed by the
    agreement. J.A. 467, 575.
    A few months after Duke and NTE entered into the Reidsville Interconnection
    Agreement, NTE persuaded three of Duke’s wholesale customers to buy power from NTE
    — McCormick, South Carolina; City of Camden, South Carolina; and Western Carolina
    University, J.A. 5395, 5989, 6071. These were significant wins for NTE. Camden, for
    example, had been a Duke customer for more than 70 years. J.A. 5476.
    As Duke continued to lose customers to NTE, Duke’s competitive concerns
    intensified. In 2017, Duke projected its all-in costs to be 30 percent higher than NTE’s
    costs for its new combined-cycle plants. J.A. 1806. In March 2018, at an all-hands
    meeting, Duke’s wholesale power segment warned that Duke’s systems were “no longer
    competitive,” although it observed that the “[p]roblem [was] mitigated by [the] long-term
    nature of [its] contracts.” J.A. 5388. Duke’s data showed that its average system cost was
    well above the cost for combined-cycle plants, such as NTE’s. J.A. 5389. In light of these
    efficiency concerns, Duke internally identified the retention of Fayetteville’s future
    business as its “biggest upcoming battle.” J.A. 5390.
    Later that spring, Duke officials sent internal emails regarding Camden’s decision
    to move its business to NTE. J.A. 5476. They also discussed a desire to keep Fayetteville
    from issuing a “Request for Proposal” (“RFP”) — a mechanism that customers use to invite
    bidders to make proposals in response to specific requests for service — to provide it with
    options for the supply of wholesale power for the years after it could terminate its
    agreement with Duke in 2024. J.A. 5476. In those emails, Duke officials recognized that
    10
    USCA4 Appeal: 22-2168      Doc: 93          Filed: 08/05/2024     Pg: 11 of 54
    “[o]ther than Fayetteville, [they] [did] not have any other contracts in the Carolinas at risk
    for several years.” J.A. 5476. The Vice President of Wholesale Power Sales informed
    other Duke officials that Fayetteville “ha[d] committed to give [Duke] an opportunity to
    modify [its] contract to meet [Fayetteville’s] needs before they go out for an RFP.” J.A.
    5476. A few months later, a Duke report indicated that its “[p]rimary proposal objectives”
    in its talks with Fayetteville “[were] to avoid RFP and retain [Fayetteville’s] load.” J.A.
    7297. To meet these goals, Duke identified an opportunity to make Fayetteville an offer
    that Duke’s competitors could not match, in part by modifying Duke’s current long-term
    contract with Fayetteville, the 2012 Power Supply Agreement. It noted, “Formula rate
    discount prior to 2024 provides value other competitors can’t offer.” J.A. 7297 (emphasis
    added).
    While Duke recognized that it “need[ed] the NTE train to stop,” NTE continued to
    attract attention with its superior efficiency. J.A. 5733. In December 2018, Stantonsburg’s
    mayor reported that a “9 percent rate cut will make Christmas a bit brighter for our
    citizens,” thanks to switching from Duke to NTE. J.A. 5894. That same month, Duke
    again projected that “the delta” — i.e., the differential — between Duke’s system costs and
    NTE’s “[was] 25 to 30 percent.” J.A. 4484.
    Despite Duke’s concern with NTE’s competition, NTE and Duke continued to
    operate under the terms of the Reidsville Interconnection Agreement throughout 2018, and
    by January 2019, NTE had paid Duke $1.6 million in security payments, as required by the
    schedule set forth in the Agreement. J.A. 575, 2019. In February of that year, however,
    Duke changed the routine payment practice. It sent NTE an email stating that it was
    11
    USCA4 Appeal: 22-2168      Doc: 93        Filed: 08/05/2024     Pg: 12 of 54
    implementing a new payment program, and NTE “should wait and send their payments per
    the instructions on the invoice, instead of just wiring it in” in accordance with the
    Agreement’s schedule. J.A. 5891–92. Only days later, Duke officials exchanged emails
    discussing its hope to “get [Fayetteville] wrapped up and [p]ut it to bed and ruin NTE’s
    plans” for the Reidsville plant. J.A. 5906. When March 1, 2019, came around — the day
    that NTE would have owed Duke a security payment under the Reidsville Interconnection
    Agreement — Duke did not send an invoice. Accordingly, in compliance with Duke’s
    instructions, NTE did not wire Duke the security payment then due. J.A. 4764–67.
    At the same time that Duke failed to send NTE invoices, it again circulated internal
    reports showing that Duke was unable to compete with NTE on efficiency: “Duke energy
    rate of ~$60-65/MWh compares unfavorably against IPPs (e.g. NTE) with offers of ~$40-
    45/MWh. Duke Energy capacity charges of ~$18/kw-month far exceed NTE’s $8/kw-
    month.” J.A. 5927. Duke continued to recognize in its internal reporting that, although
    “[m]ost wholesale contracts continue another 12-15yrs,” “Fayetteville” was the exception.
    J.A. 5927.
    Despite its relative inefficiency, Duke made a highly attractive, multi-faceted offer
    to Fayetteville, which amounted in the aggregate to a discount of $325 million for
    Fayetteville and which was unprecedented. J.A. 577, 4586. First, Duke agreed to provide
    Fayetteville with a $30/kW-year discount on its existing arrangement with Fayetteville
    from January 2021 to June 2024, which was worth approximately $42 million to
    Fayetteville. J.A. 4415. It agreed to give Fayetteville this massive discount on the rates
    set forth in its 2012 Power Supply Agreement with Fayetteville — something no other
    12
    USCA4 Appeal: 22-2168      Doc: 93         Filed: 08/05/2024     Pg: 13 of 54
    competitor could offer — but it required as a condition that Fayetteville begin to pay Duke
    more for its electricity after 2024, indeed more than NTE would have charged Fayetteville.
    J.A. 577–78, 4414–4416, 6224–27. Duke labeled this two-part discount-now increase-later
    strategy as “blend-and-extend,” and it later admitted that the strategy would enable Duke
    to charge customers like Fayetteville “higher prices than offered by the competition”
    beginning in 2024. J.A. 4663–64. And as the last part of its proposal to Fayetteville, Duke
    agreed to quadruple the price it paid for the excess power it bought from Fayetteville’s
    Butler Warner plant — increasing its purchase price from $50/kW-year to $197.82/kW-
    year. J.A. 4418–19. One Duke employee acknowledged regarding this proposal that Duke
    would pay more to Fayetteville under this arrangement than it would have to pay at market
    for the same power. J.A. 4419. Thus, under this multi-faceted proposal, Fayetteville would
    in the immediate term save money, not because Duke was more efficient, but in part
    because Duke could offer a large discount on the years during which Fayetteville was
    already locked into Duke’s services and it could provide Fayetteville with a large profit on
    Butler Warner purchases.
    After receiving Duke’s proposal, Fayetteville considered its options, hiring a
    consultant group to help it decide whether it should renew its contract with Duke or issue
    an RFP and potentially buy its electricity elsewhere, such as from NTE. Fayetteville’s
    consultants compared Duke’s offer to what it projected NTE’s would be. The consultants’
    report noted that Duke was able to cut below NTE’s rates by (1) offering a substantial
    discount on Fayetteville’s current contract and (2) offering to pay far more for energy
    coming from Fayetteville’s Butler Warner plant. J.A. 6226–27. When listing the benefits
    13
    USCA4 Appeal: 22-2168      Doc: 93         Filed: 08/05/2024     Pg: 14 of 54
    of sticking with Duke, the consultants first highlighted that Duke’s offer “provide[d]
    savings prior to 2024.” J.A. 6233. While NTE would offer a lower price for electricity
    than would be provided after the potential termination of Fayetteville’s contract with Duke
    in 2024, NTE’s offer would come with its own risks. The consultants noted disadvantages
    to doing business with NTE, including an increased potential for “cost volatility” and
    NTE’s higher credit risk. J.A. 6230.
    Subsequently, in May 2019, Fayetteville and Duke signed a Letter of Intent,
    reflecting Fayetteville’s tentative decision to renew its 2012 Power Supply Agreement with
    Duke in light of what appeared to be an attractive offer. J.A. 1391–92.
    Meanwhile, NTE was originally required to make another security payment to Duke
    under the Reidsville Interconnection Agreement on May 1, 2019. J.A. 575. But, as with
    the March 1 security payment, Duke again did not send NTE an invoice, and NTE, in
    accordance with Duke’s instructions, did not make the payment. J.A. 4764–67.
    Later that month, on May 15, 2019, NTE exercised its contractual right under the
    Reidsville Interconnection Agreement to suspend work on the construction of the
    transmission lines facility. J.A. 447, 6239. Such suspensions were common in the
    industry, and NTE’s suspension was explicitly permitted by the Reidsville Interconnection
    Agreement, which allowed NTE “to suspend at any time” so long as NTE paid Duke “for
    all reasonable and necessary costs” incurred “prior to the suspension.” J.A. 447. NTE had
    decided to suspend the Reidsville Interconnection Agreement to create some flexibility in
    its development timeline. J.A. 1493.
    14
    USCA4 Appeal: 22-2168       Doc: 93         Filed: 08/05/2024     Pg: 15 of 54
    Nonetheless, Duke interpreted NTE’s suspension and nonpayment of the security
    payments as a breach of the Reidsville Interconnection Agreement, and Duke therefore
    sent NTE a notice of breach by a letter dated May 22, 2019. J.A. 3865–68. In the letter,
    Duke also demanded payment of the security amounts for which it had not invoiced NTE.
    Duke’s letter stated that Duke had in fact sent invoices earlier, but Duke later admitted that
    that statement was false. J.A. 4764. The day Duke sent its letter, a Duke official discussing
    NTE’s suspension remarked to another, “breach! breach! punt em!” J.A. 6364.
    Important to NTE, when an IPP suspends a standard interconnection agreement,
    such suspension is not supposed to affect its placement in the queue for interconnection
    with transmission lines. FERC requires energy providers like Duke to publish information
    about their transmission capacity to industry participants and the general public through
    the online Open Access Same-Time Information System (“OASIS”). See Real-Time
    Information Networks & Standards of Conduct; Notice of Proposed Rulemaking, 
    60 Fed. Reg. 66182
    , 66188 (proposed Dec. 21, 1995) (OASIS provides “information between
    customers and providers regarding available products and desired services”); 
    18 C.F.R. § 37.2
    . And an IPP’s listing in an OASIS queue informs the public (including potential
    customers) that the IPP would be capable of transmitting the electricity it produced. Thus,
    if an IPP’s interconnection project is listed as “canceled” on an OASIS queue, that signals
    to the public — including customers and investors — that the IPP is unable to transmit its
    power.
    Duke previously had an arrangement with an independent monitor who was charged
    with the detection and reporting of anticompetitive conduct in the transmission and
    15
    USCA4 Appeal: 22-2168      Doc: 93         Filed: 08/05/2024     Pg: 16 of 54
    interconnection process, including misconduct on the OASIS queue. J.A. 4468–69. But
    Duke terminated that arrangement in March 2019, leaving it with those responsibilities.
    J.A. 4468–69.
    Duke was aware that NTE’s OASIS queue placement mattered to NTE and that it
    would be advantageous to Duke if NTE’s Reidsville project was not on track to rise to the
    top of the interconnection queue. Indeed, soon after NTE provided Duke notice of its
    suspension, a Duke official asked another, “[D]oes this mean you get to kick NTE
    Reidsville out of the queue?” J.A. 6246.
    During the summer of 2019, Duke and NTE disputed the consequences of NTE’s
    suspension under the terms of the Reidsville Interconnection Agreement, and in June 2019,
    Duke sent NTE a formal notice of default. J.A. 3870. NTE disputed that it had breached
    the agreement or defaulted in any manner, but it offered to pay Duke for the costs that it
    had incurred on the Reidsville project and for the reasonable and necessary costs caused
    by the suspension. J.A. 3874–75. Duke then sent a second notice of default and now
    demanded security payments, stating that it had earlier sent NTE invoices. J.A. 3878–81.
    Later, however, Duke again admitted that such statement was false. J.A. 4766.
    During the same period when Duke was attempting to end its arrangement with
    NTE, it also was ironing out its proposal to retain Fayetteville’s business. And in a “White
    Paper” directed to Duke’s Transaction & Risk Committee, the CEO, and the Board of
    Directors to justify the new Fayetteville proposal, Duke officials reported that “[i]f the
    environment remains as competitive as it is today . . . when [Duke’s wholesale] customers
    are ready to negotiate extensions (likely 5 years before expiration), then [Duke] will also
    16
    USCA4 Appeal: 22-2168      Doc: 93          Filed: 08/05/2024     Pg: 17 of 54
    have to offer them alternative, more competitive solutions to retain the business.” J.A.
    2847. The White Paper reported further that the “structure” of its multi-part offer to
    Fayetteville — including both the retroactive discount and Duke’s increased purchase price
    for power from the Butler Warner plant — would allow it “to retain [Fayetteville’s]
    significant load as well as retain approximately 60% of [Fayetteville’s] contribution
    towards fixed costs starting in 2024 and beyond.” J.A. 2847. Also in the White Paper, the
    Duke officials disclosed a plan to shift the cost of the discount it had offered Fayetteville
    back to its wholesale customers and to its retail customers in years to come. J.A. 2851,
    6614. Under the “best case” scenario, officials explained, Duke would cross-subsidize its
    lower rate starting in June 2024 by raising rates on these other customers, as Duke expected
    to lose $100 million on the Fayetteville deal. J.A. 2851. That “best case” scenario did not
    account for the $42 million decrease in total revenues caused by the retroactive discount
    on the charged rate from January 2021 to June 2024. J.A. 2851; see also J.A. 7003.
    On September 6, 2019, Duke unilaterally terminated the Reidsville Interconnection
    Agreement with NTE. J.A. 3894–97. While the terms of that agreement required Duke to
    notify FERC prior to any termination, Duke did not do so. J.A. 435. Later that same
    month, Duke also listed the Reidsville project as “canceled” in its OASIS queue, effectively
    “punt[ing]” NTE to the end of the line. J.A. 714, 6364. Duke did this at a time when
    NTE’s lenders were “crystal clear that the[ir] ability to finance the Reidsville project ha[d]
    everything to do with ensuring that the [Interconnection Agreement] [was] intact.” J.A.
    4529.
    17
    USCA4 Appeal: 22-2168       Doc: 93        Filed: 08/05/2024    Pg: 18 of 54
    Then, within days, Duke’s Board of Directors passed a resolution approving the new
    Fayetteville arrangement, considering the retroactive discounts to the 2012 Power Supply
    Agreement and increased payment on the Butler Warner agreement “collectively.” J.A.
    7070. And accordingly, in November 2019, while NTE’s Reidsville project was still listed
    as “canceled” in Duke’s OASIS queue, Duke and Fayetteville formally executed a new
    agreement (the “2019 Power Supply Agreement”). J.A. 911. Fayetteville signed the
    agreement without issuing an RFP to consider other offers, including NTE’s. After
    execution of the 2019 Power Supply Agreement, Duke submitted it to FERC. J.A. 3518–
    27, 3853. But it only submitted that agreement alone, which provided for the discount it
    was offering Fayetteville as a wholesale customer of electricity, and not its agreement to
    buy power back from Fayetteville’s Butler Warner plant at a quadrupled rate. J.A. 4414,
    4295–96. Duke determined internally that it “[did] not need to file the Butler Warner
    [power supply agreement] extension at FERC,” and therefore concluded that that portion
    of its agreement with Fayetteville would not pose a “[f]ederal [r]egulatory [r]isk.” J.A.
    6727.
    NTE did not seek to intervene in the FERC proceeding initiated by Duke’s filing of
    the 2019 Power Supply Agreement.         See J.A. 2359; see also 
    18 C.F.R. § 385.206
    (permitting “[a]ny person” to “file a complaint seeking [FERC] action against any other
    person alleged to be in contravention” of a law administered by the agency); 
    18 C.F.R. § 385.214
     (providing a mechanism for a person to intervene as a party in a FERC action);
    
    18 C.F.R. § 385.211
     (allowing “[a]ny person” to object to a rate filing with FERC). And
    18
    USCA4 Appeal: 22-2168      Doc: 93         Filed: 08/05/2024      Pg: 19 of 54
    on January 22, 2020, FERC approved Duke’s new selling rates, and the 2019 Power Supply
    Agreement took effect shortly thereafter. J.A. 3480–82.
    Without the hope of competing for Fayetteville’s business to justify its Reidsville
    plant, NTE’s expansion effort lost force. In November 2019, one of NTE’s business
    partners informed NTE that “Reidsville sounds like a good project . . . but we can’t make
    any commitment until the interconnection issues are resolved.” J.A. 843. Even so, NTE
    sought to move forward with the project, and it applied to the North Carolina Utilities
    Commission for a permit needed to construct the Reidsville plant. See J.A. 7162. Such
    applications rarely attracted outside involvement and were routinely granted. J.A. 4624.
    Duke, however, petitioned to intervene before the State Commission to assert that NTE
    had breached the Reidsville Interconnection Agreement and to suggest that NTE would fail
    to meet its construction goals “apparently due to a lack of financing and insufficient
    wholesale customers to justify the need for [Reidsville].” J.A. 516–17, 4293. At that time,
    however, Duke knew that NTE had won the business of some of Duke’s own customers,
    such as the City of Camden. J.A. 5476.
    In November 2019, NTE petitioned FERC, pursuant to 
    18 C.F.R. § 385.207
    (a)(2),
    for review of Duke’s unilateral termination of the Reidsville Interconnection Agreement,
    and in May 2020, FERC issued an opinion concluding that Duke’s termination was
    unlawful. J.A. 562–64. The parties, however, disagree as to the effect of FERC’s order. 3
    3
    At the parties’ request, FERC “d[id] not address the merits of any breach of
    contract claim concerning the Reidsville [Interconnection Agreement],” but it granted
    NTE’s petition “in part, by confirming [FERC’s] exclusive jurisdiction over the
    19
    USCA4 Appeal: 22-2168      Doc: 93        Filed: 08/05/2024     Pg: 20 of 54
    When FERC issued its decision, Duke still had the Reidsville project listed as “canceled”
    in its OASIS queue. Having already secured Fayetteville’s business, Duke corrected the
    OASIS queue and NTE’s placement on it after FERC’s decision issued. See J.A. 1634.
    Duke then also sent an invoice to NTE accounting for the actual costs of NTE’s
    suspension. 4 J.A. 3913–18.
    According to NTE, Duke’s actions “destroyed” “the value of the Reidsville project,”
    leaving Duke’s customers with no choice but to pay Duke’s higher rates. J.A. 4604, 4754.
    This litigation followed.
    B
    The day that Duke unilaterally terminated the Reidsville Interconnection Agreement
    — September 6, 2019 — it also sued NTE in North Carolina state court for breach of the
    agreement. J.A. 348. NTE removed the action to federal court and filed a counterclaim
    termination of conforming [interconnection agreements], clarifying a transmission
    provider’s responsibility to file a notice of termination with [FERC] when terminating a
    conforming [interconnection agreement] over an interconnection customer’s objection, and
    providing guidance on [electric quarterly reports] and OASIS postings.” J.A. 562. NTE
    says that “FERC agreed with NTE . . . that Duke’s unilateral termination of NTE’s
    agreement was unlawful,” Opening Br. at 19, whereas Duke counters that FERC
    “concluded that its approval was required to terminate, but made clear that it was not
    addressing the merits of the parties’ contract dispute,” suggesting that FERC “granted
    NTE’s petition (with Duke’s assent) [merely] in order ‘to remove uncertainty regarding the
    termination provisions in the’ Interconnection Agreement,” Response Br. at 12–13.
    4
    The district court stated that “these allegedly due payments were ultimately
    invoiced to NTE in the Summer of 2019.” Duke Energy Carolinas, 608 F. Supp. 3d at 312
    (citing J.A. 3863–68). Our de novo review of the record, however, shows that those
    summer 2019 invoices were for security payments, and Duke had sent no invoices for
    actual costs until July 2020. J.A. 3913–18.
    20
    USCA4 Appeal: 22-2168      Doc: 93         Filed: 08/05/2024     Pg: 21 of 54
    alleging that Duke had monopolized or attempted to monopolize the Carolinas wholesale
    energy market, in violation of § 2 of the Sherman Act, 
    15 U.S.C. §§ 2
    , 15. J.A. 347–416.
    NTE also alleged that Duke had violated North Carolina’s Unfair and Deceptive Trade
    Practices Act, 
    N.C. Gen. Stat. § 75-1.1
    (a); had breached the Reidsville Interconnection
    Agreement; and was liable for common law unfair competition. J.A. 408–11
    The case was assigned to U.S. District Judge Kenneth Bell. When, however, one of
    his former partners at the Virginia law firm of McGuire Woods LLP appeared as counsel
    for Duke, Judge Bell recused himself pursuant to a prophylactic policy he had adopted after
    becoming a judge for cases in which lawyers from his former firm appeared.
    Consequently, the court clerk reassigned the case to another judge, noting on the docket
    that “conflict” was the ground for doing so. The other judge presided over the case well
    into discovery until he also developed a conflict. Then, roughly two years after the case
    had been assigned to Judge Bell, it was reassigned to him, who had in the interim
    abandoned his prophylactic recusal policy. NTE filed a motion to disqualify Judge Bell
    under the principle that “once recused, a judge cannot resume authority over a case, not
    even to rescind an erroneously entered recusal order or because the conflict originally
    requiring the recusal has resolved.” J.A. 248. Judge Bell denied NTE’s motion, concluding
    that his prior recusal “did not reflect a considered ‘recusal.’” J.A. 343. He thus remained
    on the case.
    Following discovery, Duke filed a motion for summary judgment. Duke argued that
    NTE’s antitrust claims should be dismissed because NTE had failed to present evidence
    sufficient to show both that Duke held monopoly power in a relevant market and that Duke
    21
    USCA4 Appeal: 22-2168      Doc: 93         Filed: 08/05/2024      Pg: 22 of 54
    had engaged in illegal exclusionary conduct. NTE challenged Duke’s arguments based on
    the sufficiency of evidence it produced to prove its claims. It also argued that disputes of
    material facts precluded summary judgment, as a reasonable jury could find that Duke had
    monopoly power and that it had engaged in exclusionary conduct by taking actions that
    would be irrational but for their tendency to harm NTE. NTE argued that it could
    demonstrate, among other things, that Duke lost millions of dollars to stop NTE from
    competing for Fayetteville’s business; that it failed to inform FERC of the full extent of
    the discount it had offered Fayetteville; that it had unlawfully terminated the Reidsville
    Interconnection Agreement; that it had falsely published that the Reidsville project was
    “canceled” in its OASIS queue; and that it made false statements about NTE to the North
    Carolina Utilities Commission.
    In an opinion dated June 24, 2022, the district court granted summary judgment to
    Duke on NTE’s antitrust and unfair competition counterclaims.            See Duke Energy
    Carolinas, 
    608 F. Supp. 3d 298
    . While the court found a triable issue as to whether Duke
    had or was likely to achieve monopoly power, it concluded that NTE had not demonstrated
    that Duke had engaged in anticompetitive or exclusionary conduct. In reaching that
    conclusion, the court divided NTE’s allegations into discrete challenges to assess whether
    each individually amounted to an antitrust violation, addressing particularly: (1) Duke’s
    termination of the Reidsville Interconnection Agreement as a “refusal to deal” or “denial
    of an essential facility,” (2) Duke’s renewal offer to Fayetteville as “predatory pricing” or
    “fraud on FERC,” (3) Duke’s filing of its breach-of-contract lawsuit against NTE as
    “sham” litigation, (4) Duke’s erroneous OASIS posting as “defamation,” and (5) Duke’s
    22
    USCA4 Appeal: 22-2168      Doc: 93         Filed: 08/05/2024      Pg: 23 of 54
    intervention before the North Carolina Utility Commission as an additional exclusionary
    act. 
    Id. at 318
    . The court applied separate tests as relevant to each subject, found each of
    them lawful, and declined to consider the acts taken as a whole. See 
    id. at 319
    . The court
    accordingly held that NTE’s Sherman Act claims failed as a matter of law because
    “[a]dding up several instances of lawful conduct cannot total unlawful conduct” — “[i]n
    simple mathematical terms, 0 + 0 = 0.” 
    Id.
     The court also granted summary judgment to
    Duke on NTE’s state law claims of unfair competition. 
    Id.
     at 328–32.
    As for the parties’ breach of contract claims against each other, the district court
    denied summary judgment. 608 F. Supp. 3d at 332–36. The parties, however, then settled
    those claims.
    From the district court’s orders dated December 8, 2021 and June 24, 2022, NTE
    filed this appeal, challenging the denial of its motion to recuse Judge Bell and the grant of
    Duke’s motion for summary judgment on NTE’s Sherman Act claim. We address first
    NTE’s antitrust claim.
    II
    The summary judgment standard, which is on duty in this case, allows a case to be
    resolved before and without a trial when there is no genuine dispute of material fact and
    the moving party is entitled to judgment as a matter of law. Fed. R. Civ. P. 56(a). The
    court’s role in ruling on such a motion is not to assess the truth of any fact alleged or to
    weigh facts, as would a jury in finding facts, but only to determine whether facts are
    disputed and whether the disputed facts are material. See Tekmen v. Reliance Standard
    23
    USCA4 Appeal: 22-2168       Doc: 93         Filed: 08/05/2024      Pg: 24 of 54
    Life Ins. Co., 
    55 F.4th 951
    , 959 (4th Cir. 2022); Anderson v. Liberty Lobby, Inc., 
    477 U.S. 242
    , 249 (1986). In reviewing a summary judgment, we apply the same standard that the
    district court was required to apply and review the judgment de novo. W.C. English, Inc.
    v. Rummel, Klepper & Kahl, LLP, 
    934 F.3d 398
    , 402–03 (4th Cir. 2019).
    In this case, the district court entered summary judgment in favor of Duke on NTE’s
    antitrust claim, thus requiring us to determine whether material facts relevant and necessary
    to the judgment were disputed and, if not, whether the undisputed facts, taken in the light
    most favorable to NTE, entitled Duke to judgment on NTE’s § 2 claim.
    Section 2 of the Sherman Act provides in relevant part:
    Every person who shall monopolize, . . . or combine or conspire with any
    other person or persons, to monopolize any part of the trade or commerce
    among the several States, or with foreign nations, shall be deemed guilty of
    a felony . . . .
    
    15 U.S.C. § 2
    . And a plaintiff may bring a civil action when “injured in his business or
    property by reason of anything forbidden in [§ 2].” Id. § 15(a).
    The Supreme Court has held that the purpose of this law is not to protect
    competitors, but rather to safeguard the competitive process itself, ultimately for the benefit
    of consumers. See Spectrum Sports, Inc. v. McQuillan, 
    506 U.S. 447
    , 458–59 (1993). To
    that end, it has required that a plaintiff, to be successful on a § 2 claim, must satisfy two
    essential elements: (1) that the defendant “possess[ed] . . . monopoly power in the relevant
    market,” United States v. Grinnell Corp., 
    384 U.S. 563
    , 570 (1966), and (2) that the
    defendant willfully acquired or maintained that power through anticompetitive conduct, as
    24
    USCA4 Appeal: 22-2168      Doc: 93          Filed: 08/05/2024     Pg: 25 of 54
    opposed to gaining its monopoly status “as a consequence of a superior product, business
    acumen, or historic accident,” 
    id. at 571
    .
    The first element is not at issue in this appeal. Duke does not challenge the district
    court’s conclusion that a reasonable jury could find that Duke has or is likely to achieve
    monopoly power in the relevant market, given Duke’s “durably high market share,” which
    stands “at or approaching 90%.” Duke Energy Carolinas, 608 F. Supp. 3d at 315–17. But
    the second element is at issue — whether Duke maintained its power through
    anticompetitive conduct, i.e., conduct intended to “exclude rivals on some basis other than
    efficiency.” Aspen Skiing Co. v. Aspen Highlands Skiing Corp., 
    472 U.S. 585
    , 605 (1985)
    (quoting R. Bork, The Antitrust Paradox 138 (1978)).
    A monopolist does not violate § 2 by offering a superior product, service, or lower
    prices, as such conduct is procompetitive and thus increases consumer welfare. Similarly,
    a monopolist does not violate § 2 even if it attracts customers by a subpar or overly
    expensive product, as “business acumen” or “historic accident” could explain such fortune.
    Grinnell Corp., 
    384 U.S. at 571
    . Rather, a monopolist violates § 2 when it “use[s] [its]
    monopoly power ‘to foreclose competition, to gain a competitive advantage, or to destroy
    a competitor.’” Eastman Kodak Co. v. Image Tech. Servs., Inc., 
    504 U.S. 451
    , 482–83
    (1992) (quoting United States v. Griffith, 
    334 U.S. 100
    , 107 (1948)).
    To begin, we address the parties’ disagreement over the proper analysis of Duke’s
    conduct. NTE alleges that Duke engaged in several, simultaneous courses of conduct that
    combined to thwart NTE from bringing a more efficient powerplant online and ultimately
    from competing with Duke in the Carolinas wholesale power market. It argues that the
    25
    USCA4 Appeal: 22-2168      Doc: 93          Filed: 08/05/2024     Pg: 26 of 54
    district court erroneously “compartmentalized” the various aspects of Duke’s
    anticompetitive conduct and asked whether each one, independently, was unlawful.
    Opening Br. at 4, 25, 27. NTE maintains that, in approaching the record in this manner,
    the court failed to apply the correct legal standard, which required it to take account of all
    the conduct holistically and determine its effect on potential competition in the relevant
    market. It observes that in compartmentalizing Duke’s conduct for analysis, the district
    court included no discussion of the alleged anticompetitive consequences of Duke’s
    campaign as a whole — namely, reduced consumer choice, higher prices in the long term,
    and market foreclosure. Under the correct approach, it claims, the facts presented show
    that consumers were denied the choice of purchasing wholesale power from someone other
    than Duke.
    Defending the district court’s approach, Duke argues that we must reject NTE’s
    holistic approach because the Supreme Court has set forth specific tests for various kinds
    of conduct, such as refusals to deal and predatory pricing, which it argues are involved
    here, and that NTE flunks each test. Duke maintains that “NTE cannot string together a
    series of acts — all lawful in themselves under the relevant tests — and claim that the
    whole is more than the sum of the parts.” Response Br. at 46–47.
    In the context of the allegations in this case, we agree with NTE. It is foundational
    that alleged anticompetitive conduct must be considered as a whole. Section 2 focuses on
    anticompetitive conduct, not on court-made subcategories of that conduct. To be sure,
    when anticompetitive conduct is alleged to be typical predatory pricing, refusing to deal,
    price fixing, or dividing markets, as but examples, the case law has developed tests for
    26
    USCA4 Appeal: 22-2168      Doc: 93          Filed: 08/05/2024     Pg: 27 of 54
    analyzing such claims. See Novell, Inc. v. Microsoft Corp., 
    731 F.3d 1064
    , 1072 (10th Cir.
    2013). In cases where the alleged conduct falls within such well-defined categories, the
    method relied on by the district court — that 0 + 0 = 0 — is a proper approach. See, e.g.,
    Pac. Bell Tel. Co. v. linkLine Commc’ns, Inc., 
    555 U.S. 438
    , 449 (2009) (observing that
    the presented “price-squeeze claim” focused on “retail prices — where there [was] no
    predatory pricing — and the terms of dealing — where there [was] no duty to deal” and
    evaluating the plaintiffs’ claim under those two relevant tests).
    But anticompetitive conduct comes in many different forms that cannot always be
    categorized. See Conwood Co. v. U.S. Tobacco Co., 
    290 F.3d 768
    , 783–84 (6th Cir. 2002).
    Thus, when a court is faced with allegations of a complex or atypical exclusionary
    campaign, the individual components of which do not fit neatly within pre-established
    categories, its application of such specific conduct tests would prove too rigid. This is
    because “the means of illicit exclusion, like the means of legitimate competition, are
    myriad.” Verizon Commc’ns Inc. v. L. Offs. of Curtis V. Trinko, LLP, 
    540 U.S. 398
    , 414
    (2004) (cleaned up); see also Viamedia, Inc. v. Comcast Corp., 
    951 F.3d 429
    , 453 (7th Cir.
    2020) (“The fact that categories of conduct here [refusals to deal and tying] are
    conceptually related and may overlap should not cause confusion if we stay focused on the
    underlying inquiry: the conduct ‘must harm the competitive process and thereby harm
    consumers’” (quoting United States v. Microsoft Corp., 
    253 F.3d 34
    , 58 (D.C. Cir. 2001)
    (en banc))).

    Thus, when a plaintiff alleges that a scheme or course of conduct was
    anticompetitive, the scheme or conduct must be considered as alleged, not in manufactured
    subcategories. As Justice Holmes explained,
    The constituent elements . . . are enough to give to the scheme a body and,
    for all that we can say, to accomplish it. Moreover, whatever we may think
    of them separately, when we take them up as distinct charges, they are
    alleged sufficiently as elements of the scheme. It is suggested that the several
    acts charged are lawful, and that intent can make no difference. But they are
    bound together as the parts of a single plan. The plan may make the parts
    unlawful.
    Swift & Co. v. United States, 
    196 U.S. 375
    , 396 (1905). While that case was before the
    Court under § 1 of the Sherman Act, the principle also applies in the context of § 2. As the
    Supreme Court expressed in Continental Ore Co. v. Union Carbide & Carbon Corp.,
    
    370 U.S. 690
     (1962), it is a misapplication of antitrust doctrine for a court to treat a
    plaintiff’s allegations of anticompetitive conduct “as if they were five completely separate
    and unrelated lawsuits,” effectively “tightly compartmentalizing the various factual
    components and wiping the slate clean after scrutiny of each.” 
    Id.
     at 698–99. Just as the
    “character and effect of a conspiracy are not to be judged by dismembering it and viewing
    its separate parts, but only by looking at it as a whole,” 
    id. at 699
     (cleaned up), so too must
    a firm’s exclusionary efforts be considered in their totality, see Grinnell Corp., 
    384 U.S. at 576
     (affirming a judgment against a monopolist whose exclusionary campaign included
    anticompetitive restrictive agreements, pricing practices, and acquisitions). Indeed, a
    leading antitrust treatise likewise promotes the view that, in particular, exclusionary
    conduct alleged under § 2 must be considered holistically:
    28
    USCA4 Appeal: 22-2168      Doc: 93          Filed: 08/05/2024     Pg: 29 of 54
    In a monopolization case conduct must always be analyzed “as a whole.” A
    monopolist bent on preserving its dominant position is likely to engage in
    repeated and varied exclusionary practices. Each one viewed in isolation
    might be viewed as de minimis or an error in judgment, but the pattern gives
    increased plausibility to the claim.
    Phillip E. Areeda & Herbert Hovenkamp, Antitrust Law ¶ 310c7 (4th and 5th eds. 2024).
    Of course, we recognize that “care must be taken lest . . . illegality be inferred from
    procompetitive conduct.” Areeda & Hovenkamp, supra, ¶ 310c7. The easier cases are
    those in which individual practices are each independently unlawful, and so they naturally
    remain unlawful when considered together. The more challenging cases, however, are
    those in which the question is “whether two or more practices, while lawful individually,
    can be aggregated into a series or pattern capable of sustaining a Sherman Act § 2 offense.”
    Id. While such cases may be uncommon and challenging, they are not categorical
    impossibilities, for “aggregation is appropriate” when individual acts are all “part of the
    same scheme to perpetuate dominance or drive the plaintiff from the market.” Id. Thus,
    while courts must not dismember the individual acts of an exclusionary campaign when
    those acts are interconnected, they also must take care not to aggregate acts that are
    procompetitive to produce only a semblance of an exclusionary effect when considered
    together.
    With these principles in hand, we turn to NTE’s claim that it presented sufficient
    evidence to show that Duke engaged in anticompetitive conduct in the maintenance of its
    monopoly power in the relevant market based on the combined effect of two main
    components — Duke’s interference with NTE’s effort to obtain Fayetteville’s business and
    Duke’s disruption of NTE’s interconnection efforts. While we discuss these components
    29
    USCA4 Appeal: 22-2168      Doc: 93         Filed: 08/05/2024      Pg: 30 of 54
    separately because of the complex factual allegations related to each, we recognize that
    NTE claims them to be part of a singular, coordinated anticompetitive effort. And,
    ultimately, therefore, we conclude that they must be taken as alleged, considered as part of
    a single campaign to foreclose competition in the Carolinas wholesale power market.
    A
    NTE argues that Duke’s conduct in connection with its offer to Fayetteville to
    supply wholesale power to the municipality after 2024 was irrational and anticompetitive,
    designed only to exclude NTE from competition.
    When NTE announced its plans to construct the Reidsville plant, Duke identified
    Fayetteville as its “[l]argest customer risk,” noting that otherwise, given the long terms of
    its prior supplier agreements, its “portfolio [was] stable,” other than the customers it had
    already lost to NTE in 2019. J.A. 5086. Duke’s risk with respect to Fayetteville existed
    because its 2012 Power Supply Agreement with Fayetteville allowed Fayetteville to move
    its future business away from Duke, beginning in 2024. As alleged by NTE, Duke thus
    engaged in conduct to shore up Fayetteville and to exclude NTE, not for rational business
    reasons but to exclude competition.
    Duke’s take on these events is that Duke simply engaged in healthy competition. It
    “competed for Fayetteville by lowering its prices.”       Response Br. at 55.      It argues
    accordingly that NTE’s challenge to its Fayetteville offer must be viewed through the strict
    lens of a predatory pricing theory and that NTE has not shown that it could win under such
    theory. Lowering prices to retain customers is simply old-fashioned competition, and NTE
    30
    USCA4 Appeal: 22-2168        Doc: 93              Filed: 08/05/2024   Pg: 31 of 54
    did not show, according to Duke, that (1) Duke’s pricing was “below an appropriate
    measure of its . . . costs,” Brooke Group Ltd. v. Brown & Williamson Tobacco Corp.,
    
    509 U.S. 209
    , 222 (1993) and (2) there was a “dangerous probability[] of [Duke] recouping
    its investment in below-cost prices,” 
    id. at 224
    , which are the elements of a predatory
    pricing claim.
    Agreeing with Duke, the district court applied this analysis to find that Duke’s
    pricing under its 2019 Power Supply Agreement with Fayetteville was above Duke’s
    average variable costs, which, the court determined, was the appropriate measure. Duke
    Energy Carolinas, 608 F. Supp. 3d at 325–26.
    NTE argues that its challenge to Duke’s conduct was not simply based on predatory
    pricing but on a larger scope of anticompetitive conduct, maintaining more broadly that
    “the structure of Duke’s offer was exclusionary,” a contention that the district court
    overlooked altogether. Opening Br. at 50. As NTE explains it, “[t]he key structural feature
    of blend-and-extend was massive discounts and rebates conditioned on a long-term renewal
    agreement with Duke even though NTE’s rates in the renewal period — the only period
    NTE could bid for — were lower than Duke’s.” 
    Id.
     It also notes that the massive discounts
    included an agreement by Duke to purchase excess power from Fayetteville’s Butler
    Warner plant at extraordinarily high prices — above market. Thus, NTE argues that the
    district court should have considered the overall structure of Duke’s multi-faceted renewal
    offer, which NTE compares more to exclusive dealing or tying, and that the “[r]igid price-
    cost tests are . . . inapt.” Id. at 51.
    31
    USCA4 Appeal: 22-2168      Doc: 93        Filed: 08/05/2024     Pg: 32 of 54
    Because the predatory pricing approach argued by Duke focuses only on the pricing
    levels in the 2019 Power Supply Agreement, even though the extent of its massive
    discounts and NTE’s challenge both reach more broadly, we agree with NTE that the
    predatory pricing analysis cannot fully account for the more comprehensive conditions of
    Duke’s blend-and-extend strategy and the Butler Warner offering. Duke’s full offer instead
    was roughly akin to a “package discount,” such as is described by the Third Circuit:
    The anticompetitive feature of package discounting is the strong incentive it
    gives buyers to take increasing amounts or even all of a product in order to
    take advantage of a discount aggregated across multiple products. In the
    anticompetitive case, which we presume is in the minority, the defendant
    rewards the customer for buying its product B rather than the plaintiff’s B,
    not because defendant’s B is better or even cheaper. Rather, the customer
    buys the defendant’s B in order to receive a greater discount on A, which the
    plaintiff does not produce. In that case the rival can compete in B only by
    giving the customer a price that compensates it for the foregone A discount.
    LePage’s Inc. v. 3M, 
    324 F.3d 141
    , 155 (3d Cir. 2003) (quoting Areeda & Hovenkamp,
    supra, ¶ 794). In the case before us, B would refer to the product of electric power that
    both Duke and NTE sought to provide to Fayetteville after 2024, when Fayetteville could
    terminate its 2012 Power Supply Agreement with Duke. A would be the pre-2024 product
    of electric power that Duke alone could sell to Fayetteville under its 2012 Power Supply
    Agreement. And, we can say, even more inculpatory of Duke’s conduct, that A also
    includes Duke’s purchase of excess electric power from Fayetteville’s Butler Warner plant,
    again which NTE could not offer. Due to its superior efficiency, NTE would have offered
    Fayetteville a better price than Duke on B, but it was unable to offer A. Duke, meanwhile,
    rewarded Fayetteville for purchasing its more-expensive power beginning in 2024 by
    bundling that price with the massive retroactive discount on the 2012 Power Supply
    32
    USCA4 Appeal: 22-2168      Doc: 93         Filed: 08/05/2024     Pg: 33 of 54
    Agreement and the very attractive terms for purchasing excess power from the Butler
    Warner plant.
    NTE presented evidence that this packaging structure of Duke’s offer was
    anticompetitive in at least three respects. First, the blend-and-extend strategy hindered a
    new entrant’s ability to compete on the basis of efficiency with Duke for Fayetteville’s
    business after 2024. A chart produced in one of NTE’s expert reports illustrates this
    foreclosure:

    J.A. 4487. As shown in the chart, the structure of Duke’s offer was such that, even if NTE
    could offer Fayetteville a better price on power after 2024, it was severely disadvantaged
    because, as a result of the 2012 Power Supply Agreement, only Duke could provide a
    33
    USCA4 Appeal: 22-2168      Doc: 93          Filed: 08/05/2024     Pg: 34 of 54
    discount on pre-2024 prices — discounts made not for the purpose of providing a superior
    product, but for the purpose of cutting out a more efficient competitor for future years.
    Second, NTE presented evidence that Duke designed this strategy with the intent of
    foreclosing any new entrant from ever competing with it as the incumbent monopolist on
    the merits. According to Duke, its blend-and-extend strategy enabled Duke to charge
    customers “higher prices than offered by the competition” once the contract subject to the
    retroactive discount expired — here, the 2019 Power Supply Agreement. J.A. 4663–64.
    As Duke’s future prices increased, so too would the attractiveness increase of any
    retroactive discount Duke later provided under its blend-and-extend strategy. The higher
    Duke set its prices, the more flexibility it would enjoy to cut those prior prices through a
    conditional retroactive discount — returning a portion of its monopoly prices to customers
    without actually competing on efficiency grounds against new entrants. This strategy
    would permit Duke to perpetually lock out upstart competitors like NTE with well-timed
    discounts without seriously threatening its bottom line long term. While it is true that
    Duke’s wholesale rates were subject to FERC approval and that monopoly rents may well
    fall beyond the scope of what FERC would deem reasonable, see 16 U.S.C. § 824d, a jury
    could find that Duke’s blend-and-extend strategy was designed to charge consumers up to
    the limit while impeding market entry by more efficient producers. Looked at in this light,
    a factfinder could conclude that Duke’s offer did not reflect true price competition, but
    rather was designed to avoid such competition.
    Third, NTE presented evidence that the structure of the offer was anticompetitive in
    that it was designed expressly to “shift” the cost of the massive discount “back to retail and
    34
    USCA4 Appeal: 22-2168      Doc: 93         Filed: 08/05/2024      Pg: 35 of 54
    wholesale customers.”     J.A. 4421.     This strategy was similar but not identical to
    “recoupment” under a traditional predatory pricing framework. In a classic predatory-
    pricing scheme, the monopolist waits to recoup the losses it incurred by pricing a particular
    product below cost by raising its prices after the monopolist succeeds at excluding its rival
    from competing on the same product. Duke’s internal documents tell of a plan instead to
    raise prices on other of Duke’s wholesale and retail customers to make up for the profit it
    lost on the Fayetteville deal. See J.A. 6725, 6760, 6980, 7013. Duke’s projected best-case
    scenario “assumed the difference in fixed costs no longer recovered from [Fayetteville] due
    to average 190 MW monthly billing demand credit (approximately $40 million) shift back
    to retail and wholesale customers, with a 1.5-year delay in retail recovery.” J.A. 6725.
    This evidence is material because a discount forsaking some amount of profits by itself is
    not anticompetitive — lower prices, of course, enhance consumer welfare — but cross-
    subsidization can produce anticompetitive consequences, as some customers make up for
    the discount by paying higher prices. Duke’s own documents, paired with NTE’s experts’
    discussions of their anticompetitive effects, leave open a genuine factual dispute as to
    whether the structure of Duke’s Fayetteville offer was designed to cut out a more efficient
    competitor at consumers’ expense. See J.A. 4422, 4488–89. And that factual dispute
    precludes summary judgment.
    Duke argues that NTE’s challenge to the structure of Duke’s offer to renegotiate its
    existing contract with Fayetteville was “forfeited,” as NTE did not present the argument to
    the district court. Response Br. at 36. It also argues that NTE’s challenge is, in any event,
    35
    USCA4 Appeal: 22-2168       Doc: 93         Filed: 08/05/2024      Pg: 36 of 54
    “wrong,” because Brooke Group’s two-prong test must be applied to NTE’s exclusionary-
    pricing argument. Id. We find both arguments unpersuasive.
    First, NTE did make the argument below, at least in substance. Its expert gave his
    opinion that the structure of Duke’s offer was exclusionary — that Duke’s blend-and-
    extend strategy was an “exclusionary retroactive discount,” which had two features, a
    “retroactive discount and a form of deferred rebate pricing.” J.A. 4486. He explained that,
    “when a monopolist charges above a competitive price, that leaves a margin above
    competitive costs[, and] [if] the contract also has a substantial prior notice period, that
    allows the incumbent to offer a discount on the old contract and thereby exclude more
    efficient competitors.” J.A. 4486. Furthermore, in its summary judgment briefing below,
    NTE argued that the conditionality of Duke’s offer was exclusionary — “a ‘retroactive
    discount’ or rebate on an existing contract can be predatory when offered by a firm with
    market power.” J.A. 4383. And Duke recognized that NTE had argued that its “retroactive
    discount” was exclusionary in its summary judgment reply brief but argued that “[a]ny
    such claim must satisfy Brooke Group.” J.A. 7322. The record thus shows that NTE did
    not forfeit its challenge to the structure of Duke’s Fayetteville bid.
    Second, Duke argues again on appeal that NTE’s challenge to its retroactive
    discount is still precluded by Brooke Group’s holding addressing predatory pricing.
    Because Brooke Group does not provide a one-size-fits-all analytic framework for
    assessing exclusionary pricing allegations, we reject Duke’s argument that it provided the
    only applicable analysis. This is shown, for instance, by the Third Circuit’s decision in
    LePage’s Inc. v. 3M. The plaintiff in that case, a competitor in the transparent tape market,
    36
    USCA4 Appeal: 22-2168      Doc: 93         Filed: 08/05/2024     Pg: 37 of 54
    alleged that 3M had used a range of exclusionary tactics to maintain its monopoly power,
    including targeted discounts, exclusive dealing arrangements, discriminatory rebates, and
    promotional allowances. See LePage’s, 324 F.3d at 144–45.            Recognizing that the
    “relevant inquiry is the anticompetitive effect of 3M’s exclusionary practices considered
    together,” id. at 162, the court rejected 3M’s argument that each aspect of its conduct
    should be reviewed individually, and it affirmed a § 2 verdict against 3M, observing that
    the “jury had before it evidence of the full panoply of 3M’s exclusionary conduct, including
    both the exclusive dealing arrangements and the bundled rebates,” id. at 154. Rather than
    strictly applying Brooke Group, the Third Circuit thus considered 3M’s interrelated
    strategies, assessing that 3M’s foreclosure of the market was “caused by exclusive dealing
    practices [and] was magnified by [its] discount practices.” Id. at 159. It remains true that
    “[n]othing in any of the Supreme Court’s opinions in the decade[s] since the Brooke Group
    decision suggest[s] that the opinion overturned decades of Supreme Court precedent that
    evaluated a monopolist’s liability under § 2 by examining its exclusionary, i.e., predatory,
    conduct.” Id. at 152; accord ZF Meritor, LLC v. Eaton Corp., 
    696 F.3d 254
    , 277 (3d Cir.
    2012) (holding that “the rule of reason is the proper framework” for assessing whether
    conditional rebates on long-term contracts are anticompetitive because “price-cost test
    cases are inapposite” when “price itself was not the clearly predominant mechanism of
    exclusion”).
    Because we conclude that disputed facts persist regarding whether the structure of
    Duke’s offer was exclusionary, we need not assess whether the price level of the 2019
    37
    USCA4 Appeal: 22-2168       Doc: 93          Filed: 08/05/2024      Pg: 38 of 54
    Power Supply Agreement between Duke and Fayetteville, standing alone, amounted to a
    violation of § 2 under a strict predatory pricing theory of liability.
    But even if we were to focus on a strict predatory pricing theory, a factual dispute
    would remain as to whether Duke’s pricing was indeed predatory. Duke argues that it
    “stood to make $60 million profits from its Fayetteville bid, which was plainly the right
    business decision.” Response Br. at 20. But NTE’s expert calculated that Duke’s offer fell
    below its average system cost, which in this case converges with its marginal cost. J.A.
    4488–89. This could be an appropriate measure in markets with extremely high fixed costs
    and very low variable costs, as is characteristic of the wholesale power market. 5 See
    Areeda & Hovenkamp, supra, ¶ 786 (“[A] common characteristic of public utilities is
    extremely high fixed costs accompanied by very low variable costs. As a result, the
    average variable cost test . . . may give the public utility defendant too much leeway”).
    And we further note that Duke’s amici, in arguing that we should not adopt average total
    cost as the appropriate measure for gauging predation here, fail to account both for the high
    fixed costs associated with the wholesale electricity market and the fact that the price cut
    in this case resulted in the exclusion of a more efficient rival. Economics Professors Amici

    A fixed cost does not vary with output levels; a variable cost does. Average
    variable costs are the sum of variable costs divided by output. Average total costs are the
    sum of fixed and variable costs divided by output. See Areeda & Hovenkamp, supra,

    down from competitor pressure by keeping prices no lower than the average system cost”
    and reasoning that “[n]aturally, price competition can result in exclusion of less efficient
    rivals,” which does not harm consumers (emphasis added)). The parties’ experts dispute
    whether the $60 million that Duke earned from Fayetteville in its renewal contract is
    properly considered “profit” or is rather a partial recovery of its marginal costs. 6 And that
    price-cost allocation dispute should be given to the factfinder to resolve. See Greenville
    Publ’g Co. v. Daily Reflector, Inc., 
    496 F.2d 391
    , 397–98 (4th Cir. 1974).
    Duke also argues, again relying on the application of a strict predatory pricing
    analysis, that the “filed-rate” doctrine bars NTE’s challenge to Duke’s Fayetteville renewal
    offer, because FERC approved the 2019 Power Supply Agreement, deeming the rate “just
    and reasonable.” 16 U.S.C. § 824d(a). Furthermore, Duke argues, this is especially so
    here because NTE had the opportunity to intervene in FERC’s review of the 2019 Power
    Supply Agreement but did not do so. See 
    18 C.F.R. §§ 385.206
    , 385.211, 385.214. To be
    sure, the filed-rate doctrine forecloses a private suit for damages based on a claim that a
    “rate submitted to, and approved by, [a federal regulator] was the product of an antitrust
    violation.” Square D Co. v. Niagara Frontier Tariff Bureau, Inc.,

    deposition of NTE’s expert witness cited by the district court, the expert stated that under
    the “current contract, not . . . the renewal,” Duke would recover $90 million “towards fixed
    costs above variable or marginal costs,” and he did not agree that Duke’s revenues under
    the renewal contract contributed $90 million to fixed costs above variable or marginal
    costs. J.A. 7426.

    behind filing rates is that it prevents regulated firms from deviating from their published
    rates, and thus prevents discriminatory rates. Regulating rates is thus designed to protect
    customers who pay the filed rates, but not competitors who are not the intended
    beneficiaries of such a scheme. Recognizing this, the majority of courts of appeals have
    held that the filed-rate doctrine does not apply to preclude competitor suits. See Cost Mgmt.

    supra, ¶ 247c (“We agree with those decisions refusing to apply Keogh to competitor
    suits”).
    The record in this case demonstrates well why the filed-rate doctrine is ill suited for
    this competitor suit. For one, the 2019 Power Supply Agreement that Duke filed with
    FERC informed FERC only of the retroactive discount and the new rate that it agreed to
    charge Fayetteville upon renewal of the contract. Duke’s filing did not reveal either its
    cross-subsidization plan or its Butler Warner buy-back agreement, even though its
    generous pricing on that contract was an integral piece of its Fayetteville offer. Because
    Duke did not provide FERC with material aspects of its arrangement with Fayetteville,
    FERC was not invited to scrutinize the structure of Duke’s offer, which is what NTE
    maintains is the foundation of its exclusionary character. Additionally, FERC also was not
    asked to consider the exclusionary effects of Duke’s pricing structure; it determined only
    that Duke’s pricing level as revealed in the 2019 Power Supply Agreement fell within
    40
    USCA4 Appeal: 22-2168      Doc: 93         Filed: 08/05/2024        Pg: 41 of 54
    FERC’s zone of reasonableness. The limited scope of FERC’s review of Duke’s offer thus
    precludes application of the filed-rate doctrine to NTE’s exclusionary pricing allegations.
    At bottom, while Duke argues that its Fayetteville renewal offer was procompetitive
    because it lowered prices, that view is myopic in light of NTE’s claims and supporting
    evidence about the overall structure of Duke’s offer. Because a factual dispute exists
    concerning whether the structure and price level of Duke’s offer, taken together, had the
    effect of foreclosing a more efficient rival from competing, we cannot agree with Duke
    that, as a matter of law, its conduct was procompetitive.
    The record is thus sufficient to support a finding that Duke’s blend-and-extend
    strategy, coupled with its Butler Warner agreement, independently produced
    anticompetitive effects. Even so, NTE alleged that Duke’s Fayetteville strategy was but
    one prong of its alleged campaign to keep NTE from building its Reidsville plant. NTE
    alleged that there was another prong involving Duke’s additional efforts to ensure that
    NTE’s potential customers and investors did not view NTE as a viable contender in the
    Carolinas wholesale power market. We now turn to that alleged prong.
    B
    The second prong of Duke’s campaign, as NTE has alleged, was Duke’s
    interference with NTE’s effort to connect its Reidsville plant to Duke’s transmission lines,
    which included disrupting NTE’s placement in Duke’s OASIS queue and interfering with
    its application to the North Carolina Utilities Commission. Because this aspect of Duke’s
    41
    USCA4 Appeal: 22-2168       Doc: 93          Filed: 08/05/2024       Pg: 42 of 54
    conduct somewhat resembles a refusal to deal, that is the framework through which the
    parties discuss Duke’s conduct.
    Typically, firms have no duty to deal with their competitors, although in “limited
    circumstances . . . a firm’s unilateral refusal to deal with its rivals can give rise to antitrust
    liability.” linkLine, 555 U.S at 448. Applying the established principles applicable to
    refusals to deal, Duke notes that NTE needed to show (1) that both NTE and Duke, as
    competitors, were engaged in a voluntary course of dealing, and (2) that Duke refused to
    sell its goods or services to NTE on the same terms as it would to others, citing Trinko,
    540 U.S. at 408–09. It argues that NTE failed to make that showing.
    While NTE agrees that those conditions are sufficient, it argues that they are not
    necessary to establishing antitrust liability. The “ultimate test” remains whether Duke
    refused to deal in order to exclude a rival on a basis other than efficiency. Opening Br. at
    49.
    The leading case concerning refusal to deal with a competitor is Aspen Skiing, where
    the Supreme Court upheld a jury verdict against a dominant ski resort that had cut a smaller
    rival out of a joint venture to sell multiarea ski tickets. 472 U.S. at 590–94. The dominant
    ski resort failed to persuade the jury that its refusal to continue the joint ticket arrangement
    “was justified by any normal business purpose.” Id. at 608. Instead, the jury credited the
    smaller rival’s evidence of predation, which included, among other evidence, “statements
    made by the officers or agents of the company” and “evidence that the conduct was not
    related to any apparent efficiency.” Id. at 608 n.39 (cleaned up). In those circumstances,
    the Court identified the dominant firm’s termination of the prior voluntary course of
    42
    USCA4 Appeal: 22-2168       Doc: 93         Filed: 08/05/2024      Pg: 43 of 54
    dealing and refusal to sell at a retail price as sufficient conditions for establishing § 2
    liability. The main lesson of Aspen Skiing is that “it is fair to characterize [a monopolist’s]
    behavior as predatory” “[i]f [it] has been attempting to exclude rivals on some basis other
    than efficiency.” Id. at 605 (cleaned up).
    In a subsequent § 2 case arising between parties in a regulated market, the Supreme
    Court applied the principles of Aspen Skiing. See Trinko, 540 U.S. at 408–11. The Trinko
    plaintiff was an AT&T customer who claimed that Verizon delayed fulfilling its rivals’
    interconnection requests “as part of an anticompetitive scheme” to disincentivize
    customers from moving to Verizon’s rivals, “thus impeding the [rivals’] ability to enter
    and compete” in the local telephone services market. Id. at 404. The Telecommunications
    Act of 1996 required Verizon to share its network with competitors, and the Trinko plaintiff
    alleged that Verizon breached that duty and that such breach violated § 2 of the Sherman
    Act. Id. at 401. After holding that the Telecommunications Act did not preclude the
    plaintiff’s antitrust claim, the Court considered whether the challenged activity “violate[d]
    pre-existing antitrust standards,” including those articulated in Aspen Skiing. Id. at 407.
    But the Court distinguished Trinko from Aspen Skiing on two grounds. First, Aspen Skiing
    involved “[t]he unilateral termination of a voluntary (and thus presumably profitable)
    course of dealing suggest[ing] a willingness to forsake short-term profits to achieve an
    anticompetitive end.” Id. at 409. By contrast, the interconnection service Verizon was
    required to offer its rivals was not profitable to it. See id. Second, “the [Aspen Skiing]
    defendant’s unwillingness to renew the ticket even if compensated at retail price revealed
    a distinctly anticompetitive bent.” Id. By contrast, interconnection to Verizon’s own
    43
    USCA4 Appeal: 22-2168      Doc: 93         Filed: 08/05/2024     Pg: 44 of 54
    system was not something that Verizon had offered at retail price, and its “reluctance to
    interconnect at the cost-based rate of compensation,” as provided for in the
    Telecommunications Act, revealed “nothing about dreams of monopoly.” Id. The Trinko
    record contained no evidence that Verizon had abandoned a profitable deal for the purpose
    of undermining competition, and so the Court concluded that Verizon’s behavior did not
    fall within “a recognized antitrust claim under [the] Court’s existing refusal-to-deal
    precedents.” Id. at 410. Accordingly, the Court concluded that the plaintiff’s complaint
    failed to state a claim under the Sherman Act. Id. at 416.
    An important distinction between Aspen Skiing and Trinko is that Trinko — like the
    case now before us — involved a regulated market. Even so, the Trinko Court did not
    adopt a rule that unlawful refusals to deal were impossible in regulated markets. Instead,
    it instructed that “the existence of a regulatory structure designed to deter and remedy
    anticompetitive harm” was an important “factor” in an antitrust analysis because the
    existence of such a regime can lessen the need for antitrust enforcement by courts.
    540 U.S. at 412.
    Trinko’s statement that the presence of regulatory oversight is only an important
    “factor” in any antitrust analysis confirmed prior Supreme Court precedents that
    recognized that § 2 liability can arise in regulated markets. See, e.g., New York v. FERC,
    
    535 U.S. 1
    , 9 n.6 (2002). Indeed, in Otter Tail Power Co. v. United States, where the
    refusal to deal involved the wholesale power market, the Court rejected Otter Tail’s
    contention that “by reason of the Federal Power Act it [was] not subject to antitrust
    regulation with respect to its refusal to deal.” 
    410 U.S. 366
    , 372 (1973). The Court
    44
    USCA4 Appeal: 22-2168      Doc: 93         Filed: 08/05/2024     Pg: 45 of 54
    affirmed a district court judgment against Otter Tail for unlawfully refusing either to sell
    or transmit wholesale power to newly established municipal power distribution systems.
    
    Id.
     at 368–71. The municipalities had purchased Otter Tail’s distribution services before
    building their own competing systems, at which point Otter Tail refused to sell them
    wholesale power. 
    Id. at 371
    . Although Otter Tail had no prior course of dealing with the
    municipality distribution systems, the Supreme Court recognized that Otter Tail’s “refusals
    to sell at wholesale or to wheel were solely to prevent municipal power systems from
    eroding its monopolistic position.” 
    Id. at 378
    . At the time, the Federal Power Commission
    — FERC’s predecessor — “ha[d] the authority to compel involuntary interconnections,”
    but “[o]nly if a power company refuse[d] to interconnect voluntarily.” 
    Id. at 373
    . Indeed,
    the Commission had compelled interconnection for one of the municipal power systems in
    Otter Tail, 
    id. at 371
    , and yet the Court still found that Otter Tail’s refusal to deal was
    unlawful. Otter Tail thus made clear that “[a]ctivities which come under the jurisdiction
    of a regulatory agency nevertheless may be subject to scrutiny under the antitrust laws.”
    
    Id. at 372
    .
    In this case, if a jury were to resolve all factual disputes in NTE’s favor, it could
    reach the conclusion that Duke, like the defendant in Aspen Skiing, “[forsook] short-term
    profits to achieve an anticompetitive end” by unilaterally terminating the Reidsville
    Interconnection Agreement. Trinko, 540 U.S. at 409. A reasonable jury could find that
    Duke put NTE in the position of appearing to have breached its agreement with Duke,
    thereby giving Duke a justification to upset NTE’s placement in Duke’s OASIS queue.
    NTE’s apparent breach and lack of interconnection ability, in turn, would ensure that
    45
    USCA4 Appeal: 22-2168       Doc: 93        Filed: 08/05/2024     Pg: 46 of 54
    Fayetteville would not issue an RFP to NTE, thereby ultimately stalling it from bringing
    its Reidsville plant online.
    In this formulation of facts, FERC’s regulatory oversight would not foreclose
    antitrust liability. It is true that, as in Trinko, Duke only offered NTE interconnection
    services because it was compelled to do so by statute, and therefore the parties’ dealing
    was not voluntary. But the Reidsville Interconnection Agreement was profitable to Duke,
    a fact Duke does not dispute. Once NTE paid Duke $59 million to build the transmission
    infrastructure, Duke would own the infrastructure, and it would then provide transmission
    services at FERC-approved rates. See 
    18 C.F.R. § 2.22
    . Thus, in terminating that
    relationship, Duke forewent a profitable arrangement. Trinko emphasized that foregoing a
    “presumably profitable” course of dealing was one reason why the refusal to deal in Aspen
    Skiing, unlike that in Trinko itself, was anticompetitive. 540 U.S. at 409. Duke, however,
    observes that it “stood to gain ‘short-term profits’ and ‘infrastructure upgrades’ from the
    Interconnection Agreement with NTE . . . only if NTE actually paid its bills.” Response
    Br. at 31. Yet, a reasonable jury could find that Duke actually instructed NTE not to pay
    those bills and ultimately walked NTE into an apparent breach of the Reidsville
    Interconnection Agreement. Moreover, it could find that Duke sacrificed short-term profits
    as part of its concerted efforts to keep NTE from expanding its footprint in the Carolinas.
    The record includes evidence from which a jury could find that Duke sought out an
    opportunity to terminate its agreement with NTE in order to keep NTE from bringing the
    Reidsville plant online and to avoid having to compete with NTE on the merits because
    Duke believed it was at a “competitive disadvantage” efficiency-wise, which was “not
    46
    USCA4 Appeal: 22-2168      Doc: 93         Filed: 08/05/2024     Pg: 47 of 54
    going away soon.” J.A. 5086. Indeed, some evidence indicated that Duke was eager for
    NTE to “breach!” so that Duke could “punt em!” from the queue. J.A. 6364. Although
    the district court did not consider such evidence in its opinion, “the record in this case
    comfortably supports an inference that the monopolist made a deliberate effort to
    discourage its customers from doing business with its smaller rival,” Aspen Skiing,
    
    472 U.S. at 610
    , as Duke questioned whether it could “kick Reidsville out of the queue,”
    J.A. 6246, even when doing so would require Duke itself to terminate a profitable deal.
    In short, we conclude that a reasonable jury could find that Duke’s unilateral
    termination of the Reidsville Interconnection Agreement and attendant disruption of NTE’s
    place in the OASIS queue was anticompetitive conduct.
    Relying on Trinko, Duke nonetheless argues that FERC’s regulatory purview over
    its interconnection agreements forecloses NTE’s ability to complain of an antitrust refusal
    to deal. But Trinko has a more limited effect. As discussed above, in enforcing the
    Telecommunications Act of 1996, the Federal Communications Commission’s role was
    “to eliminate the monopolies.” Trinko, 540 U.S. at 415 (cleaned up). The Trinko Court
    thus observed that the Commission’s “complex regime for monitoring and enforcement”
    made it an “effective steward of the antitrust function.” Id. at 401, 413. In contrast here,
    however, FERC’s enforcement of the Federal Power Act, while aimed to promote
    competition in the market, is not designed specifically to eradicate existing monopolies.
    And, in any event, the timing of the events in this case shows that FERC’s ability to play
    any antitrust-enforcement function was limited.        Duke unilaterally terminated the
    Reidsville Interconnection Agreement in September 2019 and promptly thereafter listed
    47
    USCA4 Appeal: 22-2168       Doc: 93          Filed: 08/05/2024      Pg: 48 of 54
    NTE’s status in its OASIS queue as “canceled.” J.A. 714. Listing NTE’s status as
    “canceled” signaled to potential customers and investors that the Reidsville project would
    not move forward. And once NTE was apparently out of the picture, Duke and Fayetteville
    finalized the 2019 Power Supply Agreement. NTE did petition FERC for review of Duke’s
    unilateral termination, but by the time FERC issued an opinion agreeing with NTE, the
    damage had already been done — NTE had lost the opportunity to compete on efficiency
    grounds for an anchor customer, Fayetteville, and Fayetteville then became locked into a
    new contract with Duke for years into the future. NTE’s recourse at that point could not
    lie with FERC but with the courts. In short, FERC’s regulatory oversight, even as
    exercised, did not diminish the likelihood of significant antitrust harm because FERC was
    not timely presented with the full range of alleged anticompetitive conduct.
    Regarding NTE’s claim that Duke interfered with its efforts to interconnect with
    Duke’s transmission line, Duke asserts that it had good reasons for terminating the
    Reidsville Interconnection Agreement and canceling NTE’s position in its OASIS queue.
    Of course, if that were a true fact, Duke would not be liable for violating § 2 under a refusal-
    to-deal theory. But accepting Duke’s business justifications as fact at this stage of the
    litigation would require resolving factual disputes in favor of Duke, in violation of the
    applicable standards for summary judgment. While Duke maintains that it “stopped
    dealing with NTE only when NTE stopped paying,” Response Br. at 27, NTE presented
    evidence that it stopped paying on the Reidsville Interconnection Agreement only at
    Duke’s request.
    48
    USCA4 Appeal: 22-2168      Doc: 93         Filed: 08/05/2024      Pg: 49 of 54
    At bottom, the facts of record support a potential finding that Duke timed its
    unilateral termination of the Reidsville Interconnection Agreement to achieve
    anticompetitive ends. And we need not determine, as a matter of law, whether, if those
    facts are believed, such conduct in isolation amounted to a § 2 violation under a refusal-to-
    deal theory of liability. Rather, we recognize NTE’s claim that this conduct was but a part
    of a larger scheme. As NTE has shown, the interconnection dispute occurred during the
    very same time that Duke designed its retroactive rebate for Fayetteville to keep it from
    issuing an RFP.      On NTE’s telling of the facts, the two prongs were executed
    simultaneously and to the same effect. As a synthetic consequence, NTE could not compete
    to secure an anchor customer for its Reidsville plant, thus depriving it of any practical
    ability to bring the more efficient plant to market. Such foreclosure to competition is
    precisely what § 2 seeks to proscribe.
    C
    In discussing the two prongs of Duke’s conduct, we have pointed to material
    disputed facts — both in NTE’s claims and Duke’s responses — which are sufficient to
    preclude summary judgment at this stage of the proceedings. Upon resolution of those
    disputed facts, a jury might well conclude that Duke’s conduct was simply good, old-
    fashioned competition, which, in the end, favors the consumers of electric power in the
    relevant market. On the other hand, the factfinder might just as well conclude that Duke
    saw a more efficient competitor in NTE and acted, through a broad range of anticompetitive
    conduct in various contexts, to eliminate that competition, to the detriment of consumers.
    49
    USCA4 Appeal: 22-2168       Doc: 93             Filed: 08/05/2024   Pg: 50 of 54
    The facts supporting the parties’ conflicting positions, we conclude, are fairly disputed and
    therefore require a trial to resolve.
    And there are numerous more particular examples. For instance, as discussed at
    length, Duke asserts that it “competed for Fayetteville by lowering its prices,” Response
    Br. at 55 (citing J.A. 4188–89), but NTE asserts that “Duke offered such a massive discount
    that NTE could not win the Fayetteville contract even though it produced power more
    efficiently,” Opening Br. at 53, and that Duke planned to recoup its lowered prices after
    pushing NTE out of the market. And as we have also discussed, Duke asserts that it
    terminated the Reidsville Interconnection Agreement only after NTE breached and that it
    simply tried to recover the money NTE owed, Response Br. at 55 (citing J.A. 4180–81),
    but NTE asserts that Duke unilaterally terminated the Reidsville Interconnection
    Agreement for a pretextual reason — Duke instructed NTE not to pay until it received an
    invoice, held off on sending invoices, demanded payments that NTE did not yet owe, and
    then terminated at the time when NTE needed the contract intact in order to compete for
    Fayetteville’s business, Opening Br. at 18 (citing J.A. 3894–97). Duke asserts that it
    reported the status of the Reidsville project as required by FERC regulations and promptly
    updated its terminology from “canceled” or “terminated” to “suspended” when it was
    informed that it had erroneously categorized NTE’s project status as terminated in its
    OASIS queue, Response Br. at 55 (citing J.A. 4190–91), but NTE asserts that Duke’s
    motivation for misidentifying the suspension as a termination was, in Duke’s own words,
    to “kick NTE Reidsville out of the queue” in order to “stop” the “NTE train,” Opening Br.
    at 13 (quoting J.A. 5733); id. at 49 (quoting J.A. 6246). Duke asserts that it innocently
    50
    USCA4 Appeal: 22-2168       Doc: 93          Filed: 08/05/2024      Pg: 51 of 54
    intervened in state regulatory proceedings when NTE sought a permit for its Reidsville
    plant and that NTE “failed to disclose . . . that NTE . . . defaulted under the [Interconnection
    Agreement],” Response Br. at 55 (citing J.A. 517), but NTE asserts that “Duke falsely
    asserted to the [state agency] (among other things) that NTE lacked customers, even though
    the City of Camden had already notified Duke that it was moving its business to NTE,”
    Opening Br. at 20 (citing J.A. 515–19). Duke asserts that it “brought a meritorious contract
    claim” to recover the money NTE owed, Response Br. at 55 (citing J.A. 4189–90, 4207),
    but NTE asserts that the Duke’s suit for breach of contract was a “sham” and that it settled
    with Duke on that claim without admitting liability, Reply Br. at 5 (citing J.A. 4207).
    Alongside those disputes, NTE has presented evidence that Duke’s conduct was
    deliberate in that Duke consciously sought to exclude NTE from the relevant market
    because it was as a more efficient rival and Duke’s efforts produced that effect. See
    Grinnell Corp., 
    384 U.S. at 571
    . NTE presented evidence addressing the mens rea of
    Duke’s conduct, suggesting that it amounted to anticompetitive malice. That evidence
    bolsters our conclusion that the case is trial worthy, as we have recognized that “summary
    procedures should be used sparingly in complex antitrust litigation where motive and intent
    play leading roles.” Dickson v. Microsoft Corp., 
    309 F.3d 193
    , 212 (4th Cir. 2002) (quoting
    Poller v. Columbia Broadcasting Sys., 
    368 U.S. 464
    , 473 (1962)).
    In these circumstances, we conclude that many genuine disputes of material fact
    persist in this case, and accordingly we vacate the district court’s summary judgment and
    remand for further proceedings.

    III
    Finally, NTE contends that if we vacate the district court’s order, we should remand
    the case to a different district judge, as its motion to recuse Judge Bell under 
    28 U.S.C. § 455
    (a) should have been granted. Indeed, NTE argues that Judge Bell’s refusal to recuse
    himself serves as an independent ground to vacate the summary judgment.
    After this case was assigned to Judge Bell, a partner from his former law firm
    appeared in the case in December 2019 on behalf of Duke. At the time, Judge Bell had in
    place a standing prophylactic policy, adopted when he ascended the bench, to recuse
    himself from cases involving lawyers from his former firm, and in accordance with that
    policy, the clerk of court reassigned the case to another judge, recording the reason on the
    docket as “conflict.”
    Almost two years later, in October 2021, the judge to whom the case had been
    reassigned developed a conflict himself, and the case was then reassigned to Judge Bell
    who had by then abandoned his initial prophylactic policy. Nonetheless, NTE filed a
    motion that Judge Bell recuse himself, arguing that once a judge has recused himself in a
    case, he should not later return to that case, regardless of whether the original recusal was
    necessary or whether the original conflict had been resolved. Judge Bell denied the motion,
    concluding that his prior withdrawal “did not reflect a considered ‘recusal,’” J.A. 343, and
    NTE has appealed that order.
    Judicial partiality or bias is a fundamental and structural procedural error. See Neder
    v. United States, 
    527 U.S. 1
    , 8 (1999). And accordingly, Congress has provided that even
    if a judge’s “impartiality might reasonably be questioned,” he should recuse himself from
    52
    USCA4 Appeal: 22-2168      Doc: 93         Filed: 08/05/2024        Pg: 53 of 54
    the proceeding. 
    28 U.S.C. § 455
    (a). Indeed, even the appearance of partiality requires
    recusal.
    Judge Bell, when newly appointed, responded with appropriate sensitivity to the
    rule by recusing himself from cases in which lawyers from his former firm appeared. But
    such a prophylactic rule needed to serve only a limited, albeit sufficient, amount of time to
    create a clearly perceived distance from his former firm.
    No one contends that Judge Bell acted inappropriately when he disqualified himself
    initially, nor does anyone contend that Judge Bell acted inappropriately when he abandoned
    the initial prophylactic recusal policy. Rather, the question presented here is whether a
    judge, once he recuses himself from a case, can return to the same case later if
    circumstances have changed such that he no longer perceives himself to have a conflict or
    an appearance of one.
    For good reasons, especially for the appearance of impartiality, we have held that
    once a judge is recused, the judge is “out of service insofar as that case is concerned” and
    that he “should take no action which would possibly affect the outcome of [the] case.”
    Arnold v. Eastern Air Lines, Inc., 
    712 F.2d 899
    , 904–05 (4th Cir. 1983) (en banc)
    (discussing whether a majority of “active judges” had voted to hear a case en banc). Such
    a brightline rule can be applied with ease and promotes the goal of ensuring public
    confidence in the impartiality of the judicial process. It also accords with the practices
    adopted by several other jurisdictions, which have implemented a “once recused, always
    recused” rule. See United States v. O’Keefe, 
    128 F.3d 885
    , 891 (5th Cir. 1997) (holding
    that a judge who recused himself after granting the defendant a new trial should not have
    53
    USCA4 Appeal: 22-2168      Doc: 93         Filed: 08/05/2024      Pg: 54 of 54
    ruled on a motion for reconsideration); El Fenix de P.R. v. M/Y JOHANNY, 
    36 F.3d 136
    ,
    141 (1st Cir. 1994) (holding that a judge who has recused himself cannot reconsider the
    order of recusal); Moody v. Simmons, 
    858 F.2d 137
    , 143 (3d Cir. 1988) (holding that a
    judge should not have continued to enter non-ministerial orders after announcing his
    intention to disqualify himself because his daughter worked for one of the parties).
    In this case, because Judge Bell had previously recused himself for a potential
    conflict, prudence instructs that he should not have reentered the case, even after what the
    docket identified as a “conflict” had been resolved. See, e.g., O’Keefe, 
    128 F.3d at 891
    (“Once a judge recuses himself from a case, the judge may take no action . . . even when
    recusal is improvidently decided”); El Fenix, 36 F.3d at 141–42 (observing there was “no
    authority for” the proposition that “an improvident recusal order may be revisited by the
    recused judge”). That rule serves the judicial process well, and we adhere to it.
    But, to be clear, we do not find that Judge Bell acted inappropriately in recusing
    himself in the first instance, nor do we find that he did not allow sufficient time to pass
    before abandoning his initial policy. Rather, we simply apply our precedent that eliminates
    gray areas, public confusion, and any question about the integrity of the judicial process.
    *      *      *
    For the reasons given, we vacate the district court’s June 24, 2022 summary
    judgment order and remand to a different district judge for further proceedings.
    IT IS SO ORDERED.
