    SUMMARY **
    Medicaid
    The panel affirmed the district court’s summary
    judgment in favor of the Director of the California
    Department of Health Care Services in an action brought by
    private   ambulance      companies,     challenging    the
    reimbursement rate for their transportation of patients
    covered by Medi-Cal, the California Medicaid program.
    The reimbursement rate is set by DHCS pursuant to state
    statutes and regulations that have been approved by the
    Centers for Medicare and Medicaid Services, the federal
    agency that administers the Medicaid program on behalf of
    the Department of Health and Human Services. The
    ambulance companies alleged that their constitutional rights
    were violated because they received only 20 cents in
    reimbursement for every dollar that they spent to transport
    Medi-Cal patients.
    The panel affirmed the district court’s summary
    judgment on the ambulance companies’ claim under the
    Takings Clause. The panel held that the ambulance
    companies lacked a constitutionally protected property
    interest in a particular reimbursement rate, but the
    mandatory-care provision of Cal. Health & Safety Code
    § 1317(d) implicated a constitutionally protected property
    right. The panel held that § 1317(d) did not effect a
    regulatory taking because, under the Penn Central test, the
    ambulance companies did not establish that the statute had

    more than a negligible economic impact on them, nor that it
    interfered with their investment-backed expectations, and
    they did not provide evidence as to the character of the
    government action at issue.
    The panel held that the ambulance companies did not
    establish a due process claim regarding DHCS’s failure to
    ensure that Medi-Cal reimbursement rates kept pace with
    their costs because they lacked a constitutionally protected
    interest in any particular reimbursement rate. Under the
    rational-basis standard, the ambulance companies did not
    establish an equal protection violation regarding a
    supplemental-reimbursement program that favors public
    over private providers. The ambulance companies also did
    not establish a claim under the Contract Clause or the
    Dormant Commerce Clause.
    The panel held that there was no procedural error in the
    district court’s grant of summary judgment, and it declined
    to address claims omitted from the operative complaint.

    OPINION
    GILMAN, Circuit Judge:
    California law requires ambulance companies to provide
    emergency medical transportation irrespective of a patient’s
    ability to pay. To at least partially offset the cost of
    providing such transportation, California has an established
    reimbursement rate for those companies voluntarily enrolled
    as providers with the state’s Medicaid program (Medi-Cal)
    when they transport Medi-Cal patients. The relevant
    reimbursement rate is set by California’s Department of
    Health Care Services (DHCS) pursuant to state statutes and
    regulations that have been approved by the Centers for
    Medicare and Medicaid Services (CMS), the federal agency
    that administers the Medicaid Program on behalf of the
    Department of Health and Human Services.
    At the heart of this case is the Plaintiffs’ complaint that
    private ambulance companies receive only 20 cents in
    reimbursement for every dollar that they spend to transport
    Medi-Cal patients, a shortfall that they contend violates their
    constitutional rights. After discovery, DHCS moved for
    summary judgment, which the district court granted on all
    counts. The court held that the Plaintiffs had failed to
    produce sufficient evidence to sustain any of their claims.
    For the reasons set forth below, we AFFIRM the judgment
    of the district court.
    6         SIERRA MED. SERVS. ALLIANCE V. KENT
    I. BACKGROUND
    A. Factual background
    1. Federal Medicaid program
    Medicaid is a state-administered program financed
    jointly by the federal and state governments that provides
    healthcare coverage to low-income Americans.                See
    42 U.S.C. §§ 1396 et seq. The percentage of the program’s
    costs that the federal government covers varies by state, with
    poorer states receiving a greater share of federal dollars. See
    42 U.S.C. § 1396d(b). For the fiscal years in question,
    California bore half the cost of covering its Medicaid
    population. See 80 Fed. Reg. 73,781, tbl. 1 (Nov. 25, 2015).
    A state can satisfy its share of Medicaid spending both
    through direct appropriations to state and local Medicaid
    agencies and by certified Medicaid expenditures incurred by
    other state and local agencies. 42 C.F.R. § 433.51(a), (b).
    In exchange for receiving their allotment of federal
    funds, states design and administer Medicaid State Plans that
    must comply with federal Medicaid law. See 42 U.S.C.
    § 1396a. CMS can remedy a state’s noncompliance with
    federal Medicaid law by withholding future funding.
    42 U.S.C. § 1396c; Armstrong v. Exceptional Child Ctr.,
    Inc., 
    135 S. Ct. 1378
    , 1385 (2015) (“[T]he sole remedy
    Congress provided for a State’s failure to comply with
    Medicaid’s requirements . . . is the withholding of Medicaid
    funds by the Secretary of Health and Human Services.”).
    2. Medi-Cal
    Entities that enroll as Medi-Cal providers are entitled to
    reimbursement for the services that they provide to the
    program’s beneficiaries.       Cal. Welf. & Inst. Code
    SIERRA MED. SERVS. ALLIANCE V. KENT                  7
    § 14019.3(c), (g). The Medi-Cal statute stipulates that
    “payment received from the state in accordance with Medi-
    Cal fee structures shall constitute payment in full” for
    services provided. 
    Id. § 14019.3(d).
    And when providers
    enroll in the program, they must sign a Medi-Cal Provider
    Agreement that contains a condition to the same effect. Cal.
    Welf. & Inst. Code § 14043.2(a); Cal. Code Regs. tit. 22,
    §§ 51000.45, 51200(a), 51501(b); DHCS, Medi-Cal
    Provider Agreement (DHCS 6208) 5-6 (2017),
    http://files.medi-cal.ca.gov/pubsdoco/Publications/
    masters-other/provappsenroll/02enrollment_DHCS6208.pdf
    (“[P]ayment received from DHCS in accordance with Medi-
    Cal fee structures shall constitute payment in full . . . .”).
    DHCS administers Medi-Cal, and its responsibilities
    include setting reimbursement rates for covered services.
    Cal. Welf. & Inst. Code §§ 10740, 14105(a). In 2003, the
    agency adopted Attachment 4.19-B to California’s State
    Plan, which sets forth a “methodology” for DHCS to
    “establish[] payment rates.” State Plan Under Title XIX of
    Social Security Act: California, attach. 4.19-B, at 1,
    http://www.dhcs.ca.gov/formsandpubs/laws/Documents/Sta
    te_Plan_Attachment_4.19B_1–5.pdf. The procedures set
    forth in Attachment 4.19-B require DHCS to “develop[] . . .
    an evidentiary base or rate study” to guide its rate setting, to
    solicit public input by “present[ing] . . . the proposed rate at
    a public hearing,” and to determine a final reimbursement
    rate “based on” the aforementioned evidence and public
    input. 
    Id. 3. Reimbursement
           for       emergency        ground-
    transportation services
    Ambulance companies that operate in California must
    provide emergency services to any “person . . . in danger of
    loss of life[] or serious injury or illness” regardless of his or
    8         SIERRA MED. SERVS. ALLIANCE V. KENT
    her ability to pay. Cal. Health & Safety Code § 1317(a), (d).
    Those ambulance companies that are enrolled as Medi-Cal
    providers are entitled to at least partial reimbursement—
    $118.20 for a one-way ride—for the services that they
    provide when they transport patients who are insured
    through Medi-Cal. Cal. Welf. & Inst. Code §§ 14019.3(c),
    (g), 14132(i); Cal. Code Regs. tit. 22, § 51527. According
    to the Plaintiffs, that reimbursement accounts for only 20%
    of the actual cost that they incur to transport Medi-Cal
    beneficiaries, causing them $60 million in annual losses.
    DHCS has not promulgated new reimbursement rates for
    medical-transportation services since adopting Attachment
    4.19-B in 2003. Instead, reimbursement rates that predate
    the Attachment remain in effect. See Cal. Code. Regs. tit.
    22, § 51527. DHCS adopted those reimbursement rates in
    1984 and has amended them several times, most recently in
    2002. 
    Id. As required
    by California’s Administrative
    Procedure Act, DHCS held public hearings and provided an
    opportunity for public comment before enacting § 51527
    and each amendment thereto.            Cal. Govt. Code
    §§ 11346.45, .6. One of the Plaintiffs in this case—the
    California Ambulance Association—participated in those
    hearings. (A more extensive discussion of the regulation’s
    history is found in Sierra Med. Servs. All. v. Douglas, No.
    B220443, 
    2011 WL 985520
    , at *2–*3 (Cal. Ct. App. Mar.
    22, 2011) (unpublished).)
    California makes supplemental reimbursement available
    to publicly owned providers of emergency-medical ground
    transportation (e.g., local fire departments) for up to the
    actual cost incurred to transport Medi-Cal beneficiaries, but
    not to private providers like the Plaintiffs. Cal. Welf. & Inst.
    Code § 14105.94.         Recently, California adopted an
    additional supplemental-reimbursement program (without
    SIERRA MED. SERVS. ALLIANCE V. KENT                 9
    repealing the existing one) that is available to both private
    and public providers of emergency-medical transportation.
    See 
    id. §§ 14129–14129.7.
    B. Procedural background
    The Plaintiffs filed this action in the United States
    District Court for the Central District of California. The
    operative complaint alleges violation of the Fifth
    Amendment’s        Takings     Clause,     the   Fourteenth
    Amendment’s Due Process Clause, the Commerce Clause,
    and the Contract Clause of the United States Constitution.
    Plaintiffs also allege that the reimbursement program
    violates the Equal Protection Clause of the Fourteenth
    Amendment because public providers of emergency-
    transportation services are eligible for supplemental Medi-
    Cal reimbursement that is unavailable to private ambulance
    companies.
    Three of the Plaintiffs were involved in a prior state court
    action, which was on appeal when this case was filed. See
    Sierra Med. Servs. All., 
    2011 WL 985520
    , at *1, *3. The
    district court held that those plaintiffs could assert only an
    equal protection claim, because the remaining claims were
    barred by res judicata. Those Plaintiffs have not appealed
    that ruling.
    DHCS filed its motion for summary judgment in this
    case after the close of discovery, along with a request (to
    which the Plaintiffs objected) that the court take judicial
    notice of several items, including excerpts of California’s
    State Medicaid Plan, state legislation and legislative
    documents, materials from DHCS’s website, administrative
    records from the public hearings surrounding the adoption
    and amendment of the Medi-Cal reimbursement rate for
    medical-transportation services, and the California Court of
    10        SIERRA MED. SERVS. ALLIANCE V. KENT
    Appeal’s unpublished decision in the related case of Sierra
    Medical Services Alliance v. Douglas.
    The Plaintiffs opposed DHCS’s motion for summary
    judgment, but, before the motion was fully briefed, the
    district court stayed proceedings in light of the Supreme
    Court’s consideration of a petition for writ of certiorari in
    another case challenging Medi-Cal’s reimbursement rates.
    See Managed Pharmacy Care v. Sebelius, 
    716 F.3d 1235
    (9th Cir. 2013), cert. denied, 
    134 S. Ct. 900
    (2014) (mem.).
    After the Supreme Court denied certiorari in that case, the
    district court lifted its stay, reopened discovery for a four-
    month period, and granted the Plaintiffs permission to file a
    second opposition to DHCS’s motion for summary
    judgment, which they did after conducting additional
    discovery. After hearing argument, the district court granted
    DHCS’s motion.
    II. ANALYSIS
    A. Standard of review
    We review de novo a district court’s grant of summary
    judgment. Smith v. Clark Cty. Sch. Dist., 
    727 F.3d 950
    , 954
    (9th Cir. 2013). “Summary judgment is appropriate only if,
    taking the evidence and all reasonable inferences drawn
    therefrom in the light most favorable to the non-moving
    party, there are no genuine issues of material fact and the
    moving party is entitled to judgment as a matter of law.”
    Furnace v. Sullivan, 
    705 F.3d 1021
    , 1026 (9th Cir. 2013)
    (quoting Torres v. City of Madera, 
    648 F.3d 1119
    , 1123 (9th
    Cir. 2011)). A genuine dispute of material fact exists “if the
    evidence is such that a reasonable jury could return a verdict
    for the nonmoving party.” Anderson v. Liberty Lobby, Inc.,
    
    477 U.S. 242
    , 248 (1986). Where, as here, the party moving
    for summary judgment is not the party that bears the burden
    SIERRA MED. SERVS. ALLIANCE V. KENT                11
    of proof at trial, it may secure summary judgment by
    “‘showing’—that is, pointing out to the district court—that
    there is an absence of evidence to support the nonmoving
    party’s case.” See Celotex Corp. v. Catrett, 
    477 U.S. 317
    ,
    325 (1986).
    B. Preliminary matters
    At the outset, we will briefly address two procedural
    issues raised by the Plaintiffs on appeal. First, the Plaintiffs
    argue that the district court erred by entering judgment for
    DHCS on purely legal grounds instead of sifting through
    what the Plaintiffs contend are contrary factual assertions.
    The Plaintiffs, however, apparently misapprehend the nature
    of Rule 56 of the Federal Rules of Civil Procedure. That
    Rule “mandates the entry of summary judgment, after
    adequate time for discovery and upon motion, against a party
    who fails to make a showing sufficient to establish existence
    of an element to that party’s case, and on which that party
    will bear the burden of proof at trial.” 
    Celotex, 477 U.S. at 322
    .
    This litigation languished in the federal district court for
    five years, and not one, but two discovery deadlines elapsed
    before the court rendered judgment on DHCS’s motion. If,
    as the court found and as DHCS argues on appeal, the record
    lacks evidence upon which the Plaintiffs can sustain their
    claims, then the court properly entered judgment for DHCS.
    Second, the Plaintiffs object to DHCS’s submission of
    several public records in conjunction with its motion for
    summary judgment. But the district court’s opinion does not
    refer to any of those records, and most of them are readily
    accessible on government websites. The exceptions are the
    California Court of Appeal’s unpublished opinion in Sierra
    Medical Services Alliance v. Douglas and the exhibits from
    12        SIERRA MED. SERVS. ALLIANCE V. KENT
    the parties’ Joint Appendix in that case. There is no basis
    for the Plaintiffs to credibly claim that they were unfamiliar
    with the latter two items, however, because three of the
    Plaintiffs were themselves parties to the state-court case.
    C. Claims not raised below
    We also note that the Plaintiffs raise two substantive
    claims on appeal that do not appear in their amended
    complaint, which means that the district court had no
    opportunity to render judgment on those claims. One of
    these is the Plaintiffs’ renewal of the Supremacy Clause
    claim that they quite intentionally excluded from their
    operative, first amended complaint. As stated in their
    motion to amend, the Plaintiffs amended their initial
    complaint based on the “belie[f] that their Constitutional
    claims were stronger than their section (a)(3)(A)/Supremacy
    Clause claim.”
    The Plaintiffs waived a Supremacy Clause claim by
    omitting it from the operative complaint. See Lacey v.
    Maricopa County, 
    693 F.3d 896
    , 928 (9th Cir. 2012)
    (holding that “claims [that are] voluntarily dismissed” are
    “waived if not repled” in an amended complaint”). And
    even if the Plaintiffs could renew their Supremacy Clause
    claim, the Supreme Court’s relatively recent decision in
    Armstrong v. Exceptional Child Center, Inc., 
    135 S. Ct. 1378
    (2015), defeats it. 
    Id. at 1383
    (“[T]he Supremacy Clause is
    not the ‘source of any federal rights,’ and certainly does not
    create a cause of action.” (quoting Golden State Transit
    Corp. v. Los Angeles, 
    493 U.S. 103
    , 107 (1989))).
    Also absent from the Plaintiffs’ operative complaint is
    the argument that several different sections of the Medicaid
    statute allow for private causes of action. One of the
    sections—42 U.S.C. § 1396a(a)(30)(A)—was the statutory
    SIERRA MED. SERVS. ALLIANCE V. KENT              13
    basis for their abandoned Supremacy Clause claim. The
    Plaintiffs have never before asserted claims based on the
    other Medicaid provisions, and therefore, in the absence of
    exceptional circumstances not present here, they are
    precluded from raising those provisions for the first time on
    appeal. Fed. Ins. Co. v. Union Pac. R.R. Co., 
    651 F.3d 1175
    ,
    1178 (9th Cir. 2011).
    D. Takings Clause
    Of the claims that do appear in the Plaintiffs’ amended
    complaint, the most plausible is their Takings Clause claim,
    which we will now address. The Fifth Amendment’s
    Takings Clause prohibits the taking of “private property . . .
    for public use, without just compensation.” U.S. Const.
    amend. V. A Takings Clause claim requires proof that the
    plaintiff “possesses a ‘property interest’ that is
    constitutionally protected.” Turnacliff v. Westly, 
    546 F.3d 1113
    , 1118 (9th Cir. 2008) (quoting Schneider v. Cal. Dep’t
    of Corr., 
    151 F.3d 1194
    , 1198 (9th Cir. 1998)).
    The district court held that the Plaintiffs lack a
    constitutionally protected property interest. In doing so, it
    relied on Managed Pharmacy Care v. Sebelius, 
    716 F.3d 1235
    (9th Cir. 2013), in which this court held that “[b]ecause
    participation in Medicaid is voluntary, . . . providers do not
    have a property interest in a particular reimbursement rate.”
    
    Id. at 1252.
    The Plaintiffs respond by arguing that “[e]ven if . . .
    [they] don’t have a property right in Medicaid
    reimbursement rates, . . . their ambulances, equipment,
    wages, supplies, insurance, goodwill, and ambulatory-
    service and employment contracts . . . are also property
    rights at issue.” But, as the district court noted, the Medi-
    Cal program does not compel the Plaintiffs to furnish those
    14        SIERRA MED. SERVS. ALLIANCE V. KENT
    resources for public use.           The program provides
    compensation at predetermined rates only to those providers
    that voluntarily choose to participate.
    A separate statute, however, requires providers to render
    their emergency services “without first questioning the
    patient or any other person as to his or her ability to pay.”
    Cal. Health & Safety Code § 1317(d). This mandatory-care
    provision does not stipulate what, if any, compensation that
    providers are entitled to receive when they render services to
    Medi-Cal patients or to anyone else. It states only that “after
    the services are rendered,” “the patient or his or her legally
    responsible relative or guardian shall execute an agreement
    to pay” for the services “or otherwise supply insurance or
    credit information.” 
    Id. The district
    court did not analyze whether § 1317(d)
    effects a taking because it held that the Plaintiffs did not
    “identify, much less assert a takings claim against, the statute
    or regulation which obligates them to provide” emergency-
    transportation services without respect to the patient’s ability
    to pay. To the contrary, however, the Plaintiffs do reference
    the mandatory-care provision, albeit obliquely, in their
    amended complaint by alleging that they
    are required by law to respond to all
    emergency calls and provide emergency
    treatment and transportation to every Medi-
    Cal client that requests emergency assistance.
    [They] cannot choose to decline to treat or
    transport . . . Medi-Cal clients or even
    identify them prior to treatment or transport
    [in order] to have the option of declining to
    treat or transport them.
    SIERRA MED. SERVS. ALLIANCE V. KENT              15
    And the Plaintiffs’ appellate briefing refers to the
    compulsory effect of § 1317(d) on several occasions. These
    references to the mandatory-care provision are sufficient to
    show that the Plaintiffs intended to rely upon § 1317(d) as
    part of their Takings Clause claim.
    The district court also read Managed Pharmacy Care for
    the proposition that “providers cannot state a takings claim
    even when they are under a legal obligation to provide care.”
    But Managed Pharmacy Care’s holding is narrower and
    more nuanced. The provision at issue in that case prohibits
    nursing facilities that are enrolled as Medi-Cal providers
    from withdrawing from the program until all of their
    “Medi-Cal patients . . . are: (1) transferred to another
    facility; (2) appropriately discharged; or (3) lose
    entitlements to Medi-Cal benefits.” California Hospital
    Association v. Douglas, No. CV 11-9078 CAS (MANx),
    
    2011 WL 6820229
    at *10 & n.18 (C.D. Cal. Dec. 28, 2011),
    rev’d sub nom. Managed Pharmacy Care v. Sebelius, 
    716 F.3d 1235
    (9th Cir. 2013). By contrast, § 1317(d) applies to
    all emergency-medical-transportation providers, whether or
    not they enroll as Medi-Cal providers. And if the Plaintiffs
    unenrolled as Medi-Cal providers, the provision would
    continue to apply to them indefinitely, not for just a
    transitional period of time. Those material differences,
    along with the Plaintiffs’ property interest in their
    ambulances, equipment, wages, supplies, insurance,
    goodwill, and ambulatory-service and employment
    contracts, rather than the reimbursement rate per se, make
    Managed Pharmacy Care inapposite. Accordingly, the
    district court erred in concluding that the Plaintiffs lack a
    constitutionally protected property right upon which
    California law intrudes.
    16        SIERRA MED. SERVS. ALLIANCE V. KENT
    Because of our determination that §1317(d) implicates
    the Plaintiffs’ constitutionally protected property, we must
    next examine whether the provision effects a taking. “The
    paradigmatic taking requiring just compensation is a direct
    government appropriation or physical invasion of private
    property.” Lingle v. Chevron U.S.A. Inc., 
    544 U.S. 528
    , 537
    (2005). But a so-called “regulatory taking” can also occur
    where “government regulation of private property . . . [is] so
    onerous that its effect is tantamount to a direct appropriation
    or ouster.” 
    Id. If §
    1317(d) effects a taking, it is a regulatory
    one because DHCS does not directly appropriate the
    Plaintiffs’ ambulances or other personal property through
    the mandatory-care provision. DHCS instead regulates how
    the Plaintiffs can use their property.
    Although real property is the traditional realm of takings
    law, the Fifth Amendment also protects against the taking of
    personal property without just compensation. Horne v.
    Dep’t of Agric., 
    135 S. Ct. 2419
    , 2426 (2015) (“Nothing in
    the text or history of the Takings Clause, or our precedents,
    suggests that the rule is any different when it comes to
    appropriation of personal property.”). And voluntary
    participation in a market that is subject to regulation does not
    defeat a takings claim. See 
    id. at 2430–31
    (holding that
    raisin farmers’ voluntary decision to participate in the raisin
    market did not defeat their takings claim against the
    Department of Agriculture’s raisin-reserve requirement).
    Accordingly, § 1317(d) has the potential to effect a
    regulatory taking even though the Plaintiffs could avoid the
    regulation by simply ceasing to operate as ambulance
    companies.
    The Supreme Court has set forth an “ad hoc, factual
    inquir[y]” for determining whether a regulation amounts to
    a taking. Penn Centr. Transp. Co. v. City of New York,
    SIERRA MED. SERVS. ALLIANCE V. KENT              17
    
    438 U.S. 104
    , 124 (1978). This inquiry analyzes (1) “[t]he
    economic impact of the regulation on the claimant,” (2) “the
    extent to which the regulation has interfered with distinct
    investment-backed expectations,” and (3) “the character of
    the government action.” 
    Id. California’s mandatory-care
    provision constitutes a temporary restriction on Plaintiffs’
    use of their property, so this balancing test applies. See
    Loretto v. Teleprompter Manhattan CATV Corp., 
    458 U.S. 419
    , 435 n.12 (1982).
    This presents an insurmountable obstacle to the Plaintiffs
    because they failed to produce sufficient evidence in support
    of their takings claim under Penn Central. Starting with the
    economic-impact factor, the record simply shows that the
    Plaintiffs operate at a loss when they serve Medi-Cal
    patients. But evidence of red ink generated by serving this
    one segment of California’s population tells us nothing about
    the overall economic impact of § 1317(d). When pressed on
    this point at oral argument, counsel was unable to identify
    any relevant record evidence.           Due to the record’s
    deficiencies, we have no way of knowing the losses that the
    Plaintiffs in the present case incur as a result of § 1317(d).
    Section 1317(d) might in fact have no more than a
    negligible effect on the Plaintiffs’ bottom line, depending on
    the amount of revenue that the Plaintiffs recoup by
    transporting non-Medi-Cal patients. In the analogous case
    of Franklin Memorial Hospital v. Harvey, 
    575 F.3d 121
    (1st
    Cir. 2009), for example, a hospital brought a Takings Clause
    challenge to a Maine regulation that required it to provide
    free, medically necessary, inpatient- and outpatient-hospital
    services to residents whose incomes are at or below 150% of
    the federal poverty level. 
    Id. at 123–24
    (citing Me. Code R.
    §§ 1.01(A), 1.02(C)). Although the regulation caused the
    hospital to provide free care at an annual cost of hundreds of
    18        SIERRA MED. SERVS. ALLIANCE V. KENT
    thousands of dollars, the First Circuit concluded that the
    regulation did not amount to a regulatory taking, 
    id. at 129,
    and noted that the amount of free care that the hospital
    actually provided pursuant to the regulation equaled only
    0.51% of the hospital’s gross revenue, 
    id. at 124.
    The record is similarly lacking when it comes to the
    Plaintiffs’ investment-backed expectations, the second Penn
    Central factor. They have not identified any distinct
    expectations that they had when they entered the emergency-
    transportation market, let alone provided evidence that
    § 1317(d) has interfered with those expectations. Nor have
    the Plaintiffs provided evidence or raised any arguments as
    to the the character of the government action, the third Penn
    Central factor.
    Section 1317(d) also does not fit into either category of
    per se regulatory takings identified by the Supreme Court. It
    does not require the Plaintiffs “to sacrifice all economically
    beneficial uses” of their property, Lucas v. S.C. Coastal
    Council, 
    505 U.S. 1003
    , 1019–20 (1992) (emphasis in
    original), because neither § 1317(d) nor Medi-Cal places any
    limit on the rates that the Plaintiffs can charge to
    non-Medi-Cal patients.        And it does not constitute
    “permanent      physical     occupation       authorized   by
    government,” Loretto v. Teleprompter Manhattan CATV
    Corp., 
    458 U.S. 419
    , 422, 426 (1982), because the Plaintiffs
    also transport non-Medi-Cal patients.
    In sum, the Plaintiffs have not carried their burden of
    producing evidence upon which “a reasonable jury could
    return a verdict” in their favor. See Anderson v. Liberty
    Lobby, Inc., 
    477 U.S. 242
    , 248 (1986). The district court
    therefore did not err in entering judgment in DHCS’s favor
    on the Takings Clause claim.
    SIERRA MED. SERVS. ALLIANCE V. KENT              19
    E. Due Process Clause
    Unlike the Plaintiffs’ Takings Clause claim, which
    involves a statutory provision separate and apart from the
    Medi-Cal statutes and regulations, the Plaintiffs’ procedural
    and substantive due process claims are directed exclusively
    at DHCS’s failure to ensure that Medi-Cal reimbursement
    rates have kept pace with the Plaintiffs’ costs.
    Due process claims, like Takings Clause claims, require
    a “showing of a liberty or property interest protected by the
    Constitution.” Wedges/Ledges of Cal., Inc. v. City of
    Phoenix, 
    24 F.3d 56
    , 62 (9th Cir. 1994). As discussed above,
    the Plaintiffs voluntarily participate in Medi-Cal and
    therefore have no constitutionally protected interest in any
    particular Medi-Cal reimbursement rate (as opposed to a
    constitutionally protected interest in their ambulances and
    other personal property). See Managed Pharmacy Care v.
    Sebelius, 
    716 F.3d 1235
    , 1252 (9th Cir. 2013). Their due
    process claims are therefore without merit.
    F. Equal Protection Clause
    The Plaintiffs concede that their Equal Protection claim
    must be analyzed under a rational-basis standard. (Although
    California’s adoption of a new program in 2017 that offers
    supplemental reimbursement for the transportation of Medi-
    Cal patients, see Cal. Welf. & Inst. Code §§ 14129 14129.7,
    could muddle this analysis, the new program appears to
    complement rather than replace the supplemental-
    reimbursement program that is the focus of the Plaintiffs’
    equal protection claim. See 
    id. § 14105.94.)
    And DHCS has
    offered a perfectly reasonable justification for a
    supplemental-reimbursement program that favors public
    over private providers: payments to public providers count
    toward the state’s share of Medicaid dollars, whereas
    20        SIERRA MED. SERVS. ALLIANCE V. KENT
    payments to private providers do not. See 42 C.F.R.
    § 433.51(a), (b). Steering more Medi-Cal spending toward
    public providers is therefore in the state’s fiscal interest.
    Accordingly, the supplemental-reimbursement program
    survives rational-basis review.        See FCC v. Beach
    Commc’ns, Inc., 
    508 U.S. 307
    , 313 (1993) (“[A] statutory
    classification that neither proceeds along suspect lines nor
    infringes fundamental constitutional rights must be upheld
    against equal protection challenge if there is any reasonably
    conceivable state of facts that could provide a rational basis
    for the classification.”).
    G. Contract Clause
    A Contract Clause claim requires proof that (1) a
    contractual relationship with the state exists, (2) “a change
    in law” has occurred that “impairs that contractual
    relationship,” and (3) “the impairment is substantial.” Univ.
    of Haw. Prof’l Assembly v. Cayetano, 
    183 F.3d 1096
    , 1101–
    02 (9th Cir. 1999) (quoting Seltzer v. Cochrane, 
    104 F.3d 234
    , 236 (9th Cir. 1996)). The Plaintiffs allege that DHCS’s
    failure to issue updated reimbursement rates substantially
    impairs their contracts with cities, counties, and special
    districts that name them as the exclusive or semi-exclusive
    providers of emergency-medical-transportation services for
    the localities.
    But this is an objection to legislative inaction, not to a
    “change in law.” See 
    id. at 1101
    (quoting 
    Selzter, 104 F.3d at 236
    ). Moreover, the Plaintiffs have identified no explicit
    or even implicit term in their contracts with localities that
    DHCS has substantially impaired. Their Contract Clause
    claim therefore fails.
    SIERRA MED. SERVS. ALLIANCE V. KENT                21
    H. Dormant Commerce Clause
    This brings us to the Plaintiffs’ final cause of action, the
    one based on the so-called Dormant Commerce Clause, an
    implicit aspect of the Commerce Clause that “denies the
    States the power unjustifiably to discriminate against or
    burden the interstate flow of articles of commerce.” Rocky
    Mountain Farmers Union v. Corey, 
    730 F.3d 1070
    , 1087
    (9th Cir. 2013) (quoting Or. Waste Sys., Inc. v. Dep’t of
    Envtl. Quality of State of Or., 
    511 U.S. 93
    , 98 (1994)). On
    appeal, the Plaintiffs argue for the first time that the
    supplemental reimbursements available to public providers
    discriminate against out-of-state private providers, which
    they never pleaded in their amended complaint. And even if
    their amended complaint had alleged that the supplemental-
    reimbursement program violates the Dormant Commerce
    Clause, the relevant comparison would be between in-state
    and out-of-state public providers. Because none of the
    Plaintiffs are out-of-state public providers, they have no
    standing to challenge the supplemental reimbursements on
    Dormant Commerce Clause grounds. See Warth v. Seldin,
    
    422 U.S. 490
    , 499 (1975) (“[T]he plaintiff generally must
    assert his own legal rights and interests, and cannot rest his
    claim to relief on the legal rights or interests of third
    parties.”). Accordingly, their Dormant Commerce Clause
    claim is without merit.
    III. CONCLUSION
    For all of the reasons set forth above, we AFFIRM the
    judgment of the district court.
