    ORDER AND JUDGMENT *
    Before HOLMES, EBEL, and MATHESON, Circuit Judges.
    Plaintiff-Appellant Magdelene Lucero appeals from the district court’s
    order granting summary judgment to Defendant-Appellee Sandia Corporation,
    d/b/a Sandia National Laboratories (“Sandia”), on Ms. Lucero’s age
    discrimination and national-origin discrimination claims. For the following
    reasons, we affirm the judgment of the district court.
    *
    This order and judgment is not binding precedent, except under the
    doctrines of law of the case, res judicata, and collateral estoppel. It may be cited,
    however, for its persuasive value consistent with Federal Rule of Appellate
    Procedure 32.1 and Tenth Circuit Rule 32.1.
    I
    A
    Ms. Lucero was born in 1950 and her national origin is Hispanic. After
    graduating from highschool, Ms. Lucero began work at Sandia as a secretarial
    trainee in 1968. She rose through the ranks and, in April 2000, she became a
    member of the technical staff in Sandia’s Safeguards and Security center. Ms.
    Lucero is now retired from Sandia.
    Ms. Lucero sued Sandia, alleging, inter alia, that, during certain years
    between September 2003 and June 2008, her performance ratings (which were one
    factor affecting her annual raises) were lower than the performance ratings of
    other similarly situated employees. She alleges that this was the result of
    discrimination based on her age and national origin by her immediate manager at
    the time, Joe Sandoval. Mr. Sandoval is half Hispanic and half German.
    To determine individual raises, Sandia uses a computer program that takes
    into account many factors, including each employee’s performance rating, each
    employee’s pre-raise salary compared to the salaries of her peers, and the total
    pool of money that Sandia will allot to employee raises for a particular year. At
    Sandia, the performance rating is called the Value of Contribution (“VOC”)
    rating. There are only five possible VOC ratings. The current ratings are
    “Outstanding Contributor,” “Full Contributor–High,” “Full Contributor–Meets
    Expectations,” “Full Contributor–Low,” and “Not Fully Contributing.” J.A., Vol.
    -2-
    I, at 273 (Dist. Ct. Mem. Op. & Order, filed Jan. 3, 2011) (capitalization altered).
    Before 2006, the categories were “Outstanding Contribution,” “Full
    Contribution,” and “Not Fully Contributing.” 
    Id. at 273 n.1
    (capitalization
    altered).
    Managers determine employee VOC ratings. In doing so, they are
    constrained by the need to adhere to a curve. For each rating, a manager must
    follow certain guidelines that define the acceptable percentage of his or her
    employees that may receive that rating. For example, a manager may award no
    more than twenty-five percent of her employees a rating of “Outstanding
    Contributor,” and that ratio must be rounded down (in other words, “whether a
    manager oversees four or seven employees, he may award only one ‘outstanding
    contributor’ rating in a given year”). 
    Id. at 273. The
    VOC is the only input into the computer program that an employee’s
    direct supervisor controls, and it is the only input that Ms. Lucero claims is the
    product of discrimination, i.e., Ms. Lucero does not allege that any other factor
    influencing her raise was the product of discrimination, or that Sandia’s computer
    program, used to convert all of the inputs into a raise amount, is itself
    discriminatory. “At no point did [Mr.] Sandoval or any other individual manager
    decide the amount of [Ms.] Lucero’s raise.” 
    Id. at 274. As
    Ms. Lucero’s immediate manager from September 2003 through June
    2008; however, Mr. Sandoval assigned Ms. Lucero VOC ratings for 2004, 2005,
    -3-
    2006 and 2007. In 2004, he gave her an “Outstanding Contributor” rating and for
    the remaining three years gave her some form of “Full Contributor” rating.
    Nonetheless, Ms. Lucero alleges that Mr. Sandoval discriminated against her in
    making these VOC assignments and that it had an adverse effect on her
    employment. Because of the allegedly discriminatory assignments, Ms. Lucero
    contends that she received smaller raises. And because she received smaller
    raises, according to Ms. Lucero, she was barred from being promoted for three
    years, from 2006 through 2008, due to Sandia’s polices, which tied promotion
    eligibility to a comparative wage assessment—that is, to a determination of how
    an employee’s salary measured up (by certain percentages) to the average wage of
    other Sandia employees in her peer group.
    B
    On October 9, 2008, Ms. Lucero filed a charge with the Equal Employment
    Opportunity Commission (“EEOC”), alleging discrimination on the basis of her
    age and national origin. 1 The EEOC mailed a Notice of Right to Sue to Ms.
    1
    Significantly, in initiating her lawsuit, Ms. Lucero described in her
    filings the substance of the EEOC charge. Ms. Lucero filed, but did not
    immediately serve, her original complaint. Rather, “she exercised her right to
    amend her complaint without leave of court by filing her First Amended
    Complaint.” Dist. Ct. Doc. No. 77, at 2 (Mem. Op. & Order, filed Aug. 5, 2010);
    see Fed. R. Civ. P. 15(a)(1) (discussing amendment “as a matter of course”). As
    relevant here, in her First Amended Complaint, Ms. Lucero indicated that in her
    Title VII discrimination charge before the EEOC, she alleged discrimination “on
    the basis of race/national origin.” J.A., Vol. I, at 11 (First Amend. Compl. for
    (continued...)
    -4-
    1
    (...continued)
    Damages Due to Discrimination in Employment Based on Race/National Origin &
    Age Discrimination, filed Sept. 24, 2009). And the First Amended Complaint
    purportedly sought relief under Title VII for those (non-age) forms of
    discrimination. See 
    id. (noting that “[t]his
    action is brought [under Title VII] to
    remedy discrimination on the basis of race/national origin”).
    Under Title VII, however, race and national origin are distinct bases upon
    which to rest a discrimination charge. 42 U.S.C. § 2000e-2(a)(1) (making it
    unlawful “to discriminate against any individual . . . because of such individual’s
    race . . . or national origin” (emphasis added)); see Deravin v. Kerik, 
    335 F.3d 195
    , 201 (2d Cir. 2003) (noting that claims of race discrimination and national-
    origin discrimination are “conceptually distinct” (quoting Dixit v. City of N.Y.
    Dep’t of Gen. Servs., 
    972 F. Supp. 730
    , 734 (S.D.N.Y. 1997)) (internal quotation
    marks omitted)); see also Jefferies v. Harris Cnty. Cmty. Action Ass’n, 
    615 F.2d 1025
    , 1032 (5th Cir. 1980) (“The use of the word ‘or’ [in 42 U.S.C. § 2000e-2(a)]
    evidences Congress’ intent to prohibit employment discrimination based on any
    or all of the listed characteristics.” (emphasis added)).
    That said, we do recognize that, at least in certain factual contexts, the
    demarcation line separating the two forms of discrimination may be quite faint or
    virtually indiscernible. See 
    Deravin, 335 F.3d at 201
    (“However, courts have also
    recognized that race and national origin discrimination claims may substantially
    overlap or even be indistinguishable depending on the specific facts of a case.”);
    cf. Daemi v. Church’s Fried Chicken, 
    931 F.2d 1379
    , 1387 n.7 (10th Cir. 1991)
    (“We are cognizant, however, that often the line between national origin
    discrimination claims under Title VII and racial discrimination claims under
    § 1981 is ‘not a bright one.’” (quoting Saint Francis Coll. v. Al-Khazraji, 
    481 U.S. 604
    , 614 (1987) (Brennan, J., concurring))). Indeed, in her First Amended
    Complaint, Ms. Lucero seems to have viewed the two distinct forms of
    discrimination as essentially conterminous relative to Sandia’s alleged treatment
    of her. However, Ms. Lucero was granted leave to file a second amended
    complaint, see Dist. Ct. Doc. No. 77, at 9, and in that document, Ms. Lucero
    clarified that her EEOC charge only related to discrimination “on the basis of
    national origin and age.” J.A., Vol. I, at 123 (Second Amend. Compl. for
    Damages Due to Discrimination in Employment Based on National Origin & Age
    Discrimination, filed Aug. 11, 2010) (emphasis added). She further indicated that
    her lawsuit under Title VII related to only national-origin discrimination. 
    Id. at (continued...) -5-
    Lucero on June 23, 2009. On September 18, 2009, Ms. Lucero filed her original
    complaint in the district court asserting those same discrimination claims, plus
    several others. After the district court granted in part Sandia’s motion to dismiss
    and after Ms. Lucero declined to pursue some of her claims, all that remained on
    summary judgment were Ms. Lucero’s claims that the size of her raises and
    1
    (...continued)
    122 (noting that “[t]his action is brought [under Title VII] to remedy
    discrimination on the basis of national origin”).
    We address this matter here because Ms. Lucero’s initial conflation in her
    First Amended Complaint of the two forms of discrimination (i.e., discrimination
    on the grounds of race and national origin) appears to have contributed to a
    limited but noteworthy instance of imprecision in the district court’s summary-
    judgment analysis of her Title VII claim. Because it may engender some
    confusion, we point it out. Specifically, the district court’s analysis treats the
    terms “race” and “national origin” as essentially synonymous and uses them
    alternatively throughout its order, in some places referring to the Title VII claim
    as relating to national-origin discrimination and, in other places, referring to it as
    pertaining to race discrimination. Compare J.A., Vol. I, at 272 (noting that “the
    issues that remain before the Court are whether the raises in Plaintiff’s pay, as
    well as the restructuring of her job in 2008, were the result of discrimination
    based on Plaintiff’s age and national origin” (emphasis added)), with 
    id. at 275 (noting
    that “all that remain are [Ms. Lucero’s] claims that her raises and the
    reorganization of her job were the product of discrimination based on race and
    age” (emphasis added)). Perhaps reflecting her view that the two forms of
    discrimination are in practical terms—if not strictly legal ones—essentially
    conterminous under the circumstances of her case, Ms. Lucero has not objected to
    the district court’s summary-judgment analysis on this ground. However,
    consistent with her Second Amended Complaint, Ms. Lucero has confirmed in her
    appellate brief that her Title VII claim relates only to national-origin
    discrimination. See Aplt. Corrected Opening Br. at 3 (“This [a]ppeal contends
    that the Court engaged in error when it dismissed via summary judgment
    Appellant’s claims of age discrimination under the [Age Discrimination in
    Employment Act], and of national origin discrimination under Title VII.”).
    -6-
    certain changes in her job responsibilities were the product of discrimination
    based on age and on national origin. 2
    Recognizing that Ms. Lucero’s case rested on circumstantial evidence, the
    district court evaluated her claims under McDonnell Douglas Corp. v. Green, 
    411 U.S. 792
    (1973). The disputed issues were whether Ms. Lucero had suffered an
    adverse employment action and whether she was treated less favorably than
    similarly situated employees who were not in her protected classes.
    Regarding the allegedly discriminatory raises, the district court determined
    that Ms. Lucero failed to meet her prima facie burden under McDonnell Douglas.
    The court explained that
    in order to meet her prima facie burden, [Ms.] Lucero must
    demonstrate that there were in fact other similarly situated . . .
    employees outside her protected class who received higher raises.
    This includes more than merely identifying such allegedly
    similarly situated individuals, but also providing “evidence of
    2
    Although Ms. Lucero has made other claims against Sandia during
    the course of this lawsuit, including on appeal, the sole issue that remains after
    oral argument relates to the size of the raises she received (which were based in
    part on her performance ratings). See Oral Arg. at 12:21–12:32. Notably, at oral
    argument, Ms. Lucero abandoned her appeal of the district court’s summary-
    judgment ruling on her claim that she was discriminated against when the
    Safeguards and Security center was reorganized and her job responsibilities were
    changed. See Oral Arg. at 11:57–12:32. Consequently, as the case is currently
    postured, we need not review the district court’s decision to exclude from
    consideration “a sham issue of fact” allegedly presented in Ms. Lucero’s affidavit.
    J.A., Vol. I, at 282; see Franks v. Nimmo, 
    796 F.2d 1230
    , 1237 (10th Cir. 1986).
    The alleged “sham issue” was “whether the reorganization of the [Safeguards and
    Security center] resulted in an adverse employment action,” J.A., Vol. I, at 280,
    and that issue currently is not before us on appeal, see Oral Arg. at 11:41–12:32.

    their performance, training, education or skills.”
    J.A., Vol. I, at 278 (citation omitted) (quoting Amro v. Boeing Co., 
    232 F.3d 790
    (10th Cir. 2000)). The district court determined that because Ms. Lucero had
    provided no evidence “comparing [Ms.] Lucero’s performance, education, skills,
    and accomplishments . . . to those of other [members of the technical staff]
    outside the protected class who received higher ratings and higher raises than she
    received,” Ms. Lucero “[could not] demonstrate that she was indeed ‘similarly
    situated’ to the other employees.” 
    Id. at 279. The
    court also held that Ms. Lucero “failed to meet her prima facie burden
    to show that her raises amounted to an adverse employment action,” because,
    according to the court, “the evidence shows that in each year from 2003 to 2008,
    she received a raise that was within the range of raises given to her peers.” 
    Id. The court reasoned,
    “This hardly supports an inference that any of [Ms.] Lucero’s
    raises constituted an adverse employment action, especially absent any evidence
    comparing her performance, education, and skills to those outside the protected
    class who received higher raises.” 
    Id. at 280. Having
    determined that Ms. Lucero had not met her burden on the
    “similarly situated” and “adverse employment action” elements of her prima facie
    case, the court nevertheless proceeded to address the two remaining steps of the
    McDonnell Douglas analysis. It found that Sandia had articulated a legitimate,
    non-discriminatory reason for Ms. Lucero’s lesser raises, and that the “evidence
    -8-
    of a legitimate, nondiscriminatory reason is undisputed.” 
    Id. at 284. Finally,
    the
    court determined that Ms. Lucero “failed to come forward with evidence that
    Sandia’s explanation of her raises was mere pretext” for unlawful discrimination.
    
    Id. at 285. The
    district court granted Sandia’s summary-judgment motion in its
    entirety.
    Ms. Lucero timely filed this appeal, and the only issue before us is whether
    the district court properly entered summary judgment against Ms. Lucero on her
    age and national-origin claims related to her allegedly discriminatory raises.
    II
    A
    We review the district court’s order granting summary judgment de novo,
    and we draw all reasonable inferences in favor of the nonmoving party—in this
    case, Ms. Lucero. See Trentadue v. Integrity Comm., 
    501 F.3d 1215
    , 1226 (10th
    Cir. 2007). “[S]ummary judgment is appropriate ‘if the movant shows that there
    is no genuine dispute as to any material fact and the movant is entitled to
    judgment as a matter of law.’” Morris v. City of Colo. Springs, 
    666 F.3d 654
    , 660
    (10th Cir. 2012) (quoting Fed. R. Civ. P. 56(a)).
    Ms. Lucero’s only remaining claims of discrimination are that she received
    lower raises than the younger, non-Hispanic coworkers, because of her age and
    national origin. Under the Age Discrimination in Employment Act (“ADEA”), it
    is unlawful for an employer to “discriminate against any individual with respect
    -9-
    to [her] compensation . . . because of such individual’s age,” 29 U.S.C. §
    623(a)(1), if that individual is forty or older, 
    id. § 631(a) (“The
    prohibitions in
    this chapter shall be limited to individuals who are at least 40 years of age.”); see
    8 Lex K. Larson, Employment Discrimination § 120.01, at 120-2 (2d ed. 2011)
    (noting that the ADEA “forbids age discrimination in employment of persons at
    least forty years of age” and generally there is “no longer an upper age for
    protection”). Likewise, under Title VII, it is an unlawful employment practice for
    an employer “to discriminate against any individual with respect to [her]
    compensation . . . because of such individual’s . . . national origin.” 42 U.S.C.
    § 2000e–2(a)(1); see, e.g., Khalik v. United Air Lines, 
    671 F.3d 1188
    , 1192 (10th
    Cir. 2012); Zamora v. Elite Logistics, Inc., 
    478 F.3d 1160
    , 1164 (10th Cir. 2007)
    (en banc).
    Here, there is an absence of direct evidence of discrimination. Rather, Ms.
    Lucero has attempted to prove discrimination through circumstantial evidence
    under the McDonnell Douglas framework, which is properly employed in
    analyzing such evidence under both Title VII and the ADEA. See McDonnell
    
    Douglas, 411 U.S. at 802
    (Title VII); Simmons v. Sykes Enters., Inc., 
    647 F.3d 943
    , 947 (10th Cir. 2011) (ADEA).
    Ms. Lucero carries the initial burden of establishing a prima facie case of
    age or national-origin discrimination. See McDonnell 
    Douglas, 411 U.S. at 802
    .
    -10-
    Only if Ms. Lucero can make out her prima facie case does the burden shift to
    Sandia to articulate some legitimate, nondiscriminatory reason for its actions. See
    
    id. In order to
    prove her case through circumstantial evidence, Ms. Lucero must
    show that she was “given a lesser raise[] than other similarly situated non-
    protected class employees.” 
    Amro, 232 F.3d at 798
    .
    “[W]hether employees are similarly situated—i.e., whether they are ‘similar
    in all material respects,’—is a fact-intensive inquiry, and what facts are material
    will vary depending on the case.” Hawn v. Exec. Jet Mgmt., Inc., 
    615 F.3d 1151
    ,
    1157 (9th Cir. 2010) (citation omitted) (quoting Nicholson v. Hyannis Air Serv.,
    Inc., 
    580 F.3d 1116
    , 1125 (9th Cir. 2009)); accord Good v. Univ. of Chi. Med.
    Ctr., 
    673 F.3d 670
    , 675 (7th Cir. 2012) (“To determine whether a plaintiff’s
    co-worker was similarly situated for purposes of this analysis, a court must make
    a ‘flexible, common-sense’ evaluation of the relevant factors.” (quoting Henry v.
    Jones, 
    507 F.3d 558
    , 564 (7th Cir. 2007))). Compare Moran v. Selig, 
    447 F.3d 748
    , 755–56 (9th Cir. 2006) (holding that the plaintiffs—white baseball
    players—had failed to establish a prima facie case of disparate treatment under
    Title VII because the African-American baseball players they used as comparators
    were not similarly situated; the African-American baseball players had been
    excluded from playing in the Major Leagues on account of their race, and it was
    primarily this material difference that prompted Major League Baseball to
    provide a benefit to African-American players that was not available to white
    -11-
    players), with McGuinness v. Lincoln Hall, 
    263 F.3d 49
    , 54–55 (2d Cir. 2001)
    (holding that the plaintiff had established a prima facie case of discrimination
    under Title VII where both she and a male comparator had been fired, and she
    alleged discrimination in the amount of severance that she received, because she
    had “established that she and [the male comparator] held positions of roughly
    equivalent rank . . . , that [they] were fired at roughly the same time, that the
    decisions with respect to the severance were both made at the highest levels of the
    company, and that [the comparator] received considerably more money in
    severance”).
    Here, Ms. Lucero has failed to establish her prima facie case, and summary
    judgment was warranted on that ground. Our decision in Amro is particularly
    instructive. We explained the plaintiff’s failing in Amro as follows:
    [Mr. Amro] asserts that his pay raise was less than the raises
    received by 92% of the engineers in his classification. However,
    he fails to demonstrate that there were in fact other similarly
    situated engineers outside his protected class who received higher
    raises. After carefully reviewing the record, we agree with the
    district court that “although [Mr. Amro] has identified others who
    allegedly are similarly situated engineers, he has not provided
    any evidence of their performance, training, education or skills.
    [Mr. Amro’s] own opinion that his performance is excellent does
    not raise a fact question as to how his performance compares to
    others.” Amro [v. Boeing Co., 
    65 F. Supp. 2d 1170
    , 1186 (D.
    Kan. 1999)]; see also Jones v. Denver Post Corp., 
    203 F.3d 748
    ,
    754 (10th Cir. 2000) (“‘It is the manager’s perception of the
    employee’s performance that is relevant, not plaintiff’s
    subjective evaluation of his own relative performance.’”)
    (quoting Furr v. Seagate Tech., Inc., 
    82 F.3d 980
    , 988 (10th Cir.
    -12-
    1996)). In essence, Mr. Amro alleges “[t]he simple fact that [he]
    did not receive as high a raise as [he] feels he is worth.” Murphy
    v. Yellow Freight Sys., Inc., 
    832 F. Supp. 1543
    , 1550 (N.D. Ga.
    1993). That is 
    insufficient. 232 F.3d at 798
    (first and fourth alterations added). 3 As in Amro, Ms. Lucero has
    failed to provide any evidence that the comparators that she has put forth are
    similarly situated, much less evidence that she and those comparators were
    similar in all material respects. More specifically, Ms. Lucero has provided no
    evidence regarding the training, education, or skills of the Sandia employees who
    received higher raises. Mr. Sandoval’s testimony underscores the significance of
    this failing of proof. Mr. Sandoval explained in his deposition that Ms. Lucero’s
    co-workers included employees who “were all doing unique kinds of activities,”
    and that Ms. Lucero was, in some years, “competing [for VOC ratings] against
    some very highly technical people doing very highly technical work.” J.A., Vol.
    I, at 164 (Dep. of Joseph Sandoval, taken Mar. 31, 2010). In 2005, for example,

    A panel of our court reached a similar conclusion in a non-
    precedential decision. See Welder v. Univ. of Okla. Bd. of Regents,

    table case) (affirming the district court’s order granting summary judgment on the
    plaintiff’s claim that “the University discriminated against her by paying her a
    lower salary than male professors in her College,” because “the evidence d[id] not
    show that plaintiff was similarly-situated to any male who received higher pay”);
    see also Taher v. Wichita State Univ., 
    526 F. Supp. 2d 1203
    , 1219 (D. Kan. 2007)

    he had not established that any other employees to whom the defendant had given
    higher pay raises were similarly situated).

    Id. at 163. And
    others had master’s degrees in
    business administration and one had a master’s degree in national security. Ms.
    Lucero (who only possessed a highschool diploma) failed to offer proof that she
    was similarly situated to those or other Sandia employees.
    At bottom, Ms. Lucero’s assertion of a viable prima facie case (regarding
    the similarly situated component) rests solely on an alleged concession made by
    Sandia that the other members of the technical staff of Ms. Lucero’s workgroup
    were similarly situated. Sandia attached as an exhibit to its motion for summary
    judgement information regarding all of the members of the technical staff of the
    Safeguards and Security center, including their performance ratings, ages, races,
    salaries, and raises from 2003 through 2008. In its filings, Sandia referred to the
    other members of the technical staff as Ms. Lucero’s “peers.” For example,
    Sandia averred that Ms. Lucero’s “salary increases and [VOC ratings] were
    commensurate with those of her peers.” J.A., Vol. I, at 37–38 (Def.’s Mot. for
    Summ. J., filed July 12, 2010) (referring to the compensation data for all of the
    members of the technical staff in the Safeguards and Security center); see also 
    id. at 44 (“[Ms.
    Lucero’s] raises were not out of step with her peers[’].”
    (capitalization altered)); 
    id. at 44–45 (“The
    lowest raise for [Ms. Lucero’s] peer
    group [in September 2007] was 1.3%.”); 
    id. at 45 (“Only
    three of twelve peers
    -14-
    received larger raises than [Ms. Lucero] did [in September 2008] . . . .”). 4
    In response to Sandia’s motion for summary judgment, Ms. Lucero pointed
    to the data provided by Sandia to show that she received lower raises than her
    younger, non-Hispanic counterparts. Regarding the purported concession, she
    wrote in a footnote: “Sandia cannot argue that [Ms. Lucero’s] comparisons are not
    with ‘similarly situated employees’ because Sandia identified Plaintiff’s ‘peers’
    as the [members of the technical staff], and [Ms. Lucero’s] comparison tables are
    exclusively based on [the salary information in Sandia’s exhibit].” 
    Id. at 149 n.7
    (Pl.’s Resp. to Sandia’s Mot. for Summ. J., filed Aug. 23, 2010) (emphasis
    altered).
    Ms. Lucero now claims that because Sandia relied on the data regarding the
    other members of the technical staff in an effort to show that Ms. Lucero was not
    treated less favorably than younger, non-Hispanic employees, Sandia has
    conceded that the other members of the technical staff were—in the eyes of the
    law—similarly situated. Sandia vigorously contests the notion that it made such a
    concession.
    4
    Furthermore, in discussing Ms. Lucero’s now-withdrawn First
    Amendment claim, Sandia wrote: “[T]he relevant context is [Ms. Lucero’s] raises
    when viewed against those of her similarly-situated peers who did not engage in
    the same sort of speech as [Ms. Lucero]. Some of [Ms. Lucero’s] raises—as well
    as her overall salary—were as great as or greater than her peers who did not raise
    safety concerns.” J.A., Vol. I, at 52.
    -15-
    Sandia essentially argues that it used the term “peers” in referring to the
    other members of the technical staff because they constituted the conceivable
    possible universe of employees from which Ms. Lucero might endeavor to
    identify similarly situated employees to establish her prima facie case. And, by
    “showing that [Ms.] Lucero was not disadvantaged in comparison with her co-
    workers [i.e., her peers],” Aplee. Br. at 13, who were not members of an age or
    national-origin protected group, Sandia sought to demonstrate a proof deficiency
    of Ms. Lucero’s prima facie case and to shift the burden to her on summary
    judgment (as the non-movant) to come forward with sufficient evidence—in
    particular, evidence that she was treated less favorably than similarly situated
    non-protected employees. This line of argument, insists Sandia, “was not a
    concession that [Ms.] Lucero’s peers [i.e., the other members of the technical
    staff] were similarly situated to her.” 
    Id. at 11. In
    other words, reasons Sandia,
    it was not conceding that Ms. Lucero actually could successfully identify
    similarly situated comparators—as that concept is understood in our
    precedent—(among the other members of the technical staff or otherwise), but
    instead it was just “shift[ing] the burden onto [Ms.] Lucero to show that she
    possessed [all] necessary evidence.” 
    Id. at 12. In
    our view, Sandia has the more cogent position in this dispute, and we
    reject Ms. Lucero’s concession claim. In doing so, we acknowledge that Sandia’s
    summary-judgment briefing was not a model of clarity. For example, Sandia did
    -16-
    not expressly explain its rationale in using the term “peers” (even though it could
    be gleaned with some attention from the substance and context of its argument),
    and it cited our decision in Johnson v. Weld County, 
    594 F.3d 1202
    (10th Cir.
    2010), which at best is only remotely related to the similarly situated prima facie
    matter. Indeed, in Johnson, we “assume[d] without deciding” that plaintiff had
    established her prima facie 
    case. 594 F.3d at 1211
    . However, at least one thing
    was pellucid from Sandia’s summary-judgment briefing: Sandia was not relieving
    Ms. Lucero of her burden to establish that she was treated less favorably than
    similarly situated comparators. In this regard, Sandia threw down the gauntlet in
    patent terms, stating that “[Ms. Lucero] could not establish that she was treated
    less favorably than younger or non-Hispanic Sandians who were similarly situated
    to herself.” Aplee. Br. at 11. 5 At that juncture, it was incumbent upon Ms.
    5
    Even if we were willing to accept (which we are not) that Ms. Lucero
    could have reasonably believed that Sandia conceded in its summary-judgment
    filing that the other members of the technical team were similarly situated to her
    under the law—and thus relieved her of the proof burden on that element of her
    prima facie case—Sandia’s reply brief would have bluntly disabused her of that
    notion. In its summary-judgment reply brief, Sandia stated that “it is [Ms.
    Lucero’s] burden at this stage to demonstrate that similarly situated employees
    were treated more favorably. This is not simply a matter of pointing out non-
    Hispanics or younger people who received larger raises. It involves establishing
    that these individuals are similar to [Ms. Lucero] in ways that influence raises.”
    J.A., Vol. I, at 198 (Def.’s Reply in Supp. of Mot. for Summ. J., filed Sept. 14,
    2010). Reviewing the overall substance of its argument, Sandia clearly and
    unequivocally controverted its alleged “concession”—by pointing out that the
    similarly situated burden of proof fell on Ms. Lucero; by citing Amro; and by
    concluding that Ms. Lucero “has not established a prima facie case of dissimilar
    (continued...)
    -17-
    Lucero to ascertain the legal requirements for similarly situated comparators and
    identify fellow employees (presumably other members of the technical staff) that
    qualified under those legal requirements. This she did not do.
    In sum, because Ms. Lucero has failed to provide any evidence that she was
    treated differently from any similarly situated employees, who were not in
    protected classes based on age or national origin, she has failed to make out a
    prima facie case of discrimination. Accordingly, her claim fails on the first step
    of the McDonnell Douglas burden-shifting analysis. On this ground, we affirm
    the district court’s summary-judgment ruling in favor of Sandia.

    Id. Even if at
    no other time, when she received Sandia’s reply brief,
    Ms. Lucero was on clear notice that Sandia did not concede—and had not
    conceded—that Ms. Lucero’s fellow members of the technical staff were similarly
    situated. At that point, if Ms. Lucero truly felt she had been misled, she was
    obliged to take whatever protective steps were necessary to place before the court
    evidence to support the similarly situated component of her prima facie case (e.g.,
    seeking leave to file a surreply).

    Ms. Lucero also filed with us an unopposed motion to seal what she
    called her “Brief-in-Chief.” Pl.’s Unopposed Mot. to Place Her Brief-in-Chief
    Under Seal at 1 (filed Apr. 8, 2011). The subject of her motion—i.e., the Brief-
    in-Chief—had been filed on April 4, 2011. Ms. Lucero represented to this Court
    that the brief contained “certain evidence . . . which had been placed under seal at
    the District Court and which should not be made available for public disclosure.”

    clerk’s office of our court provisionally granted the motion, pending our final
    determination. Although we sound a cautionary note, we ultimately grant the
    motion to seal.
    “A party seeking to file court records under seal must overcome a
    presumption, long supported by courts, that the public has a common-law right of
    access to judicial records.” Eugene S. v. Horizon Blue Cross Blue Shield of N.J.,
    
    663 F.3d 1124
    , 1135 (10th Cir. 2011). Accordingly, “the parties must articulate a
    real and substantial interest that justifies depriving the public of access to the
    records that inform our decision-making process.” Helm v. Kansas, 
    656 F.3d 1277

    “take the necessary steps to correct the matter in her Corrected
    Brief-in-Chief when it is filed.” 
    Id. at 2. Our
    clerk’s office provisionally granted
    this motion to seal, pending our final determination of the matter. Ms. Lucero did
    file a corrected opening brief, which the clerk’s office substituted for her initial
    Brief-in-Chief. The clerk’s office purged the latter document from its files.
    Accordingly, the original Brief-in-Chief is no longer available in any form to the
    public in the files of this court. Therefore, we DENY the motion to seal as moot.
    To avoid any confusion, we further note that on the cover of Ms. Lucero’s
    corrected brief, she mistakenly stated that it should be filed under seal subject to
    the provisional sealing order of our clerk’s office, which in fact only related to
    the initial Brief-in-Chief. The clerk’s office followed Ms. Lucero’s lead and
    mistakenly filed the corrected brief under seal. At the close of oral argument, the
    parties suggested that the corrected opening brief should be treated as a public
    document. See Oral Arg. 32:40–59, 34:42–46. The clerk’s office subsequently
    confirmed that this brief was sealed in error and clarified in its records that the
    corrected opening brief is publicly accessible.

    8A Charles Alan Wright, et al., Federal Practice & Procedure § 2042, at 234 (3d
    ed. 2010) (“The strongest arguments for access apply to materials used as the
    basis for a judicial decision of the merits of the case, as by summary judgment.”);
    see also Brown & Williamson Tobacco Corp. v. FTC, 
    710 F.2d 1165
    , 1177 (6th
    Cir. 1983) (“Throughout our history, the open courtroom has been a fundamental
    feature of the American judicial system. Basic principles have emerged to guide
    judicial discretion respecting public access to judicial proceedings. These
    principles apply as well to the determination of whether to permit access to
    information contained in court documents because court records often provide
    important, sometimes the only, bases or explanations for a court’s decision.”).
    In their joint motion, by way of justification, the parties simply stated,
    “The documents in Volume II of the Corrected Joint Appendix consist of
    documents that were filed under seal in the district court pursuant to a court
    order.” Joint Mot. to File Vol. II of Corrected J.A. Under Seal at 2 (filed Apr. 18,
    2011). The parties included with the motion a copy of the district court’s one-
    page sealing order, in which the court summarily noted that it was sealing
    evidence with Ms. Lucero’s date of birth and evidence with confidential
    information.
    At the outset, in light of the well-settled presumption against denying
    -20-
    public access to judicial documents, we feel obliged to underscore that parties
    should not routinely or reflexively seek to seal materials upon which they
    predicate their arguments for relief, particularly dispositive relief such as
    summary judgment. Furthermore, a district court’s decision to seal certain
    pleadings or evidence certainly is not controlling with respect to our independent
    determination to maintain the same items under seal on appeal. Accordingly,
    parties would be well advised to affirmatively offer justifications for the
    continued sealing of materials. This did not happen here: the parties sole
    proffered justification for sealing Volume II of the Corrected Joint Appendix was
    that the district court had elected to seal the items that were in that volume.
    Nonetheless, to better assess the merits of the pending motion to seal
    Volume II, we have taken the initiative of reviewing certain filings in the district
    court related to the sealing question. They reveal that the documents sought to be
    sealed contain confidential information relating to Sandia’s personnel and
    business practices—in particular its method of determining compensation and the
    actual compensation of certain nonparty employees. As the district court noted in
    describing one such sealed document in its summary-judgment ruling, it contains
    detailed information regarding the name, age, ethnicity, salary,
    VOC rating, base pay, and non-base pay of each of the other
    [members of the technical staff] in [Ms.] Lucero’s organization
    from 2003 to 2008, as well as information regarding how well
    each of them was compensated as compared with the private
    market for individuals with similar skills, and the rate at which
    -21-
    each was compensated compared to Sandia peers.
    J.A., Vol. I, at 278 n.4. Further, in Volume II, there is an excerpt from the
    transcript of Ms. Lucero’s deposition, in which she gives the exact date of her
    birth. 7
    In light of our investigation of the merits of the pending motion to seal, we
    conclude that the parties’ confidentiality concerns are sufficiently weighty that
    Volume II of the Corrected Joint Appendix should remain under seal. See
    Sorenson Commc’ns, Inc. v. FCC, 
    659 F.3d 1035
    , 1041 n.4 (10th Cir. 2011)
    (making orders to seal the parties’ briefs and a portion of the joint appendix
    permanent “to protect confidential information relating to [the defendant’s]
    finances and business practices”). Therefore, we maintain the seal imposed
    provisionally by our clerk’s office with respect to Volume II of the Corrected
    Joint Appendix. 8
    7
    The federal rules provide protections against the public disclosure of
    more than the year of birth. See, e.g., Fed. R. Civ. P. 5.2(a)(2); Fed. R. App. P.
    25(a)(5).

    In contrast to the documents themselves contained in Volume II, we
    note that we would not have shied away from disclosures of the information
    contained in the documents, if it had proved necessary for our disposition of this
    appeal. Compare Qwest Corp. v. FCC, --- F.3d ----, 
    2012 WL 3156451

    Because Ms. Lucero has failed to make out a prima facie case of

    Appendix.

    (...continued)
    district court has adopted the findings of a sealed pre-sentence report, it is
    appropriate (i.e., necessary) to address those findings, in order to resolve
    challenges to the district court’s sentencing decisions). The public’s interest in
    access to the grounds for judicial decision-making would have warranted at least
    that much. Indeed, the district court followed such a course in its summary-
    judgment ruling—disclosing limited information in sealed documents that was
    necessary to its ruling, including general information regarding Sandia’s
    personnel data. See J.A., Vol. I, at 278 n.4 (“Due to the private nature of such
    information [in sealed documents], the Court will discuss the data generally but
    will not refer to any of those individuals by name.”). The parties have not
    objected to the district court’s approach, and they would be hard-pressed to do so.
    Benefitting from the district court’s very limited general disclosures of
    information in the sealed documents, in resolving the issues in this appeal, we
    have felt no need to make further disclosures of information found in the sealed
    documents, and we have endeavored scrupulously not to do so.
