RILEY, Chief Judge.

      Thomas Nash filed suit against Optomec, Inc., alleging the company fired him
on account of his age in violation of the Minnesota Human Rights Act (MHRA),
Minn. Stat. §§ 363A.01, et seq. The district court1 granted Optomec’s motion for

      1
      The Honorable Richard H. Kyle, United States District Judge for the District
of Minnesota.
summary judgment, finding Nash failed to establish a prima facie case of age
discrimination, and even if he had, there was insufficient evidence to suggest the
lawful reason Optomec gave for its decision was pretext for an underlying unlawful
motive. Nash appeals, see 28 U.S.C. § 1291 (appellate jurisdiction), and we affirm.

I.      BACKGROUND
        In fall 2011, Nash enrolled in the nanoscience technology program at Dakota
County Technical College (Dakota Tech). Some time later, Nash and his classmates
toured Optomec’s advanced applications lab in St. Paul, Minnesota, which develops
3-D printing systems. Nash needed to complete an internship in order to finish his
program, and after the tour, he decided to pursue one with Optomec. Two interviews
later, John Lees, Optomec’s then-49-year-old Vice President of Engineering, offered
Nash a full-time paid internship for the summer and fall of 2013. The offer did not
contain any guarantee of post-internship employment, nor did either party have that
understanding. Nash was 54 years old when he was offered and accepted the position.

        During his tenure at Optomec, Nash’s duties included taking measurements,
recording data, and operating and maintaining the lab equipment. Nash performed
these duties alongside three interns: Travis Evans, Chenxing Pei, and Dan Bakke, each
of whom was an engineering student at the University of Minnesota and in his early
twenties.2 Nash claims Lees began exhibiting a “pattern of preference” for these
younger interns almost immediately. According to Nash, he received the “cold
shoulder” from Lees, while Evans was sent on expenses-paid work trips and Pei made
$2 more per hour than he did. Notably, neither Pei nor Bakke were ever sent on work
trips, and Evans and Bakke both made $16 per hour just as Nash.



      2
       Evans began working for Optomec before Nash did, and became an engineer
with the company after his internship ended. Pei was hired shortly after Nash, and left
in December 2013. Bakke began his internship in January 2014, and accepted
employment elsewhere after his internship ended in August 2014.

                                         -2-
       Nash’s internship ended in December 2013. Despite believing he was treated
less favorably than his peers, Nash described his experience positively in post-
internship reports to Dakota Tech. Nash also felt he was “very well prepared” for the
internship and gave himself high marks in various performance-related categories for
his self-assessment. In comparison, the district court accurately summarized
Optomec’s evaluation of Nash as “fairly tepid.” Though commending his spreadsheet
skills and “much appreciated discipline and rigor,” Lees noted that tasks requiring
“physical skill or dexterity” were difficult for Nash and “[u]nderstanding and
troubleshooting systems [was] also a bit beyond him.” Lees expressed his belief that
“[p]revious interns had more learning potential.”

       When Nash received his associates degree from Dakota Tech he immediately
inquired about a permanent position with Optomec. Lees spoke with John Wright, an
engineer at Optomec, about the idea of hiring Nash. Wright, age 52, echoed Lees’s
concerns: Nash “wasn’t a particularly skilled technician” and “required very specific
instructions and step-by-step instructions on how to complete a task.” But despite
Wright’s criticism and his own apprehension, Lees offered Nash a full-time position.
Nash, now 55 years old, accepted and began work as an at-will employee in January
2014.

        As Optomec’s lone full-time lab technician, Nash worked on several projects
over the following months that he claims demonstrated his hard work, value, and skill.
 Still, according to Nash, Lees continued to treat the younger interns more favorably
in many of the same ways he had during Nash’s internship. For example, Evans
continued to be sent on work trips that “gave him troubleshooting and teamwork
experiences not offered to Nash.” Nash felt “humiliated” when Lees “went to great
lengths to highlight his concern to other employees” about Bakke’s exposure to
hazardous chemicals after a lab spill in April 2014. Lees expressed no such concern
about Nash’s exposure despite the fact Nash, not Bakke, led the cleanup effort.



                                         -3-
        As Nash’s concerns were apparently mounting, so too were Optomec’s. By
May 2014, Nash had amassed a considerable amount of experience, but his abilities
had not grown like Wright and Lees had hoped. According to Wright, Nash “did well
at following explicit instructions, but when you asked him to step back and maybe
look at things []holistically, he struggled with putting that all together.” Lees agreed,
and believed “[Nash] was not—not progressing beyond the kind of basic lab
skills. . . . [S]ome of the issues with his performance were not getting better.” Nash’s
struggles with troubleshooting and critical thinking were an even bigger problem
when Lees began to look ahead: “The business was growing. There was going to be
a need to support more customers. We needed just a higher level of functionality
across the board on the team.” This realization led Lees to change his views as to
what he wanted from lab technicians—he now considered it “a way to bring people
into the technology” in hopes they would “grow and progress beyond that point.” To
Lees, Nash had not exhibited the capacity to “take it to that next level.” Lees shared
his concerns with David Ramahi, Optomec’s Chief Executive Officer, who left the
decision up to Lees, but encouraged him to “be decisive and take action.”

       Lees fired Nash on June 6, 2014, less than six months after he had hired him.
Lees told Nash the decision “was not performance related,” but that the company was
going in a “different direction.” The parties dispute exactly what happened next, yet
both sides agree Nash was upset and the situation became tense as Nash complained
about the lack of warning and claimed he was being discriminated against. A few
days later, Nash exercised his right under Minnesota law to request a letter from
Optomec explaining why he was fired. See Minn. Stat. § 181.933, subdiv. 1. In its
response, Optomec noted Nash’s performance was “satisfactory in terms of
performing more menial tasks,” but ultimately explained he “unfortunately [did] not
possess the full breadth of skills required to successfully meet the challenges required
of [his] position,” like independent troubleshooting.




                                          -4-
       Nash filed an administrative charge with the Minnesota Department of Human
Rights, which found no probable cause to believe unlawful discrimination occurred
and issued him a right-to-sue letter. Nash filed suit against Optomec for age
discrimination in violation of Minn. Stat. § 363A.08, subdiv. 2(2).3 After discovery,
the district court granted Optomec’s motion for summary judgment, deciding Nash
failed to establish his prima facie case under the familiar McDonnell Douglas burden-
shifting analysis. The district court bolstered its decision by finding that even if Nash
could satisfy his initial burden, “Optomec has proffered a legitimate,
nondiscriminatory reason” and there was insufficient evidence “to create a genuine
issue of fact as to pretext.” Nash appeals.

II.    DISCUSSION
       “We review the district court’s grant of summary judgment de novo and may
affirm on any basis supported by the record.” Tenge v. Phillips Modern Ag Co., 

, 906 (8th Cir. 2006). We view the evidence in the light most favorable to
Nash, see Torgerson v. City of Rochester, 

, 1042 (8th Cir. 2011) (en
banc), and will affirm the dismissal only if “there is no genuine dispute as to any
material fact,” Fed. R. Civ. P. 56(a). But if the record taken as a whole “‘could not
lead a rational trier of fact to find for [Nash], there is no genuine issue for trial’” and
summary judgment was proper. 

(quoting Ricci v.
DeStefano, 

, 586 (2009)).

          The MHRA prohibits an employer from discharging an employee “because
of . . . age.” Minn. Stat. § 363A.08, subdiv. 2(2). With few exceptions, “[w]e analyze
MHRA claims using the same standards we apply to claims under the federal Age




      3
       Nash brought this action in state court, but Optomec—a Delaware corporation
with its principal place of business in New Mexico—removed the case to federal
court. See 28 U.S.C. § 1332(a)(1) (diversity jurisdiction); 

(removal).

                                           -5-
Discrimination in Employment Act [(ADEA)].”4 Chambers v. Travelers Cos., 

, 566 (8th Cir. 2012). See generally 29 U.S.C. §§ 621, et seq. Optomec
provided a non-discriminatory reason for firing Nash and “[t]he record was fully
developed in the district court . . . so we may turn directly to the question whether
[Nash] has presented sufficient evidence to raise a genuine issue for trial on the
ultimate question of age discrimination vel non.” Noreen v. PharMerica Corp., 

, 992 (8th Cir. 2016).

       We begin by noting our agreement with the district court that “[t]he fact that
Evans and Bakke might have assumed Nash’s duties for a short time does not suggest
that age played a part in Nash’s termination.” Although replacement by substantially
younger employees may allow for an inference of discrimination, the “important
datum” is the age of Nash’s permanent replacement, Lewis v. St. Cloud State Univ.,

, 1136-37 (8th Cir. 2006), and here there simply was none. Even if we
accept Nash’s position that his duties went exclusively to Evans and Bakke—which
requires ignoring Nash’s admission that he does not know who assumed his duties and
Wright’s (age 52) testimony that he had to “pick up” most of them—such workload
redistribution was temporary. That Nash was terminated around the time Evans and
Bakke returned to full-time status does not change the fact their internships were
scheduled to (and indeed, did) end in August 2014.

      Moving on, the overarching reason Optomec gave for firing Nash was that he
lacked the skill set and potential Optomec wanted from lab technicians to account for

      4
       One possible exception relates to Nash’s ultimate burden under the MHRA.
Optomec calls for the but-for standard applicable to ADEA plaintiffs. See, e.g., Rahlf
v. Mo-Tech Corp., 

, 636-37, 636 n.2 (8th Cir. 2011). Nash counters that
MHRA plaintiffs need only show age was a “motivating factor.” See, e.g., Noreen v.
PharMerica Corp., 

, 992-94 (8th Cir. 2016). The district court took the
prudent approach by applying the “less-stringent ‘motivating factor’ standard,” and
we will do the same because we agree Optomec is entitled to summary judgment
under either standard.

                                         -6-
the company’s anticipated growth. Nash argues this explanation has “no basis in fact”
because his shortcomings (e.g., independent troubleshooting) were not part of his job
description or ever asked of him. This argument misses the point. As the district
court recognized, it was the company’s “vision for the future of the lab technician
position, and Nash’s inability to fit that vision, that led to his dismissal.” We are not
convinced by Nash’s suggestion that this is a “similar situation” to Gaworski v. ITT
Commercial Finance Corp., 

, 1110 (8th Cir. 1994), where we questioned
the employer’s claim that it fired the plaintiff for inferior computer skills. There, the
employer did not tell the plaintiff that it considered computer skills “‘critical’” even
though the plaintiff had demonstrated an “ability to grasp new concepts” and the
employer admitted that, if asked, the plaintiff probably could have learned the
computer system. 

Optomec noted from the very beginning and
throughout litigation its belief both that Nash lacked the ability to adequately
troubleshoot issues and that he exhibited little ability to progress and acquire new
skills. There is no evidence to suggest Optomec failed to notify Nash—an at-will
employee and not entitled to any advance warning under company policy—of his
alleged deficiencies “for fear that he might correct them.” Ryther v. KARE 11, 

, 841 (8th Cir. 1997) (en banc). To the contrary, Optomec hired Nash despite
these shortcomings in hopes that he would correct them, but he did not.

        Nash next argues Optomec changed its explanation in a way that suggests an
underlying discriminatory animus. It is true an employer’s shifting explanation can
be probative of discriminatory motive, but our case law is clear the change must be
“‘substantial.’” Johnson v. Securitas Sec. Servs. USA, Inc., 

, 613 (8th
Cir. 2014) (en banc) (quoting Bone v. G4S Youth Servs. LLC, 

, 957 (8th
Cir. 2012)). Nash tries to construct a “substantial difference” by contrasting Lees’s
initial statement that the decision “was not performance related” with the subsequent
letter from Optomec’s corporate counsel explaining Nash lacked “the full breadth of
skills required to successfully meet the challenges required” of his position. We do
not consider this a substantial change when, as here, various employees explain or

                                          -7-
elaborate on the decision to fire the plaintiff in ways that are slightly different, but
nonetheless consistent with the overall reason stated by the employer. See 

satisfied every explanation in the record fits with the general notion that, although
Nash’s performance was “satisfactory in terms of performing more menial tasks,”
Optomec believed he lacked the skills or capacity to “grow” alongside the company
and fill their anticipated needs.

       Nash also contends Lees exhibited favoritism towards the younger interns, but
the district court’s well-reasoned opinion correctly characterized Nash’s evidence as
“‘weak and not probative of discrimination.’” (Quoting Pivirotto v. Innovative Sys.,
Inc., 

, 359 (3d Cir. 1999)). True, Nash was never afforded the
opportunity to travel on Optomec’s behalf as Evans was, but neither was Pei or Bakke,
and there is no reason to discredit the unrebutted testimony that Lees sent Evans
because of his superior experience, skill, and success with previous trips. Cf.

(noting instances of alleged disparate treatment are only
probative if the comparators are “similarly situated in all relevant respects—a rigorous
standard” (internal quotation marks omitted)). In his deposition, Lees justified Pei’s
higher pay rate on the basis “[h]e was an outstanding student and an exceptional
young engineer.” Nash clings to Lees’s use of “young,” but “young” could be
synonymous with “new,” and we consider this to be a textbook example of a “stray
remark” unrelated to the decisional process. See Twymon v. Wells Fargo & Co., 

, 933-34 (8th Cir. 2006). The district court was correct to disregard the other
“trivial matters,” such as the chemical spill and the perceived “cold shoulder.” See
Sprenger v. Fed. Home Loan Bank of Des Moines, 

, 1113 (8th Cir.
2001) (“[W]e hesitate to rely on isolated comments as proof of bias lest the law
become a ‘general civility code.’” (citation omitted) (quoting Oncale v. Sundowner
Offshore Servs., Inc., 

, 80 (1998))).

      We are similarly unconvinced by Nash’s other arguments. Nash points to
instances where Lees criticized him for “physical dexterity issues,” an “inability to

                                          -8-
think on his feet,” and “stubbornness” to suggest Lees harbored ageist stereotypes that
motivated his decision. However unlike the cases Nash cites, see, e.g., Hilde v. City
of Eveleth, 

, 1005-06 (8th Cir. 2015) (retirement age), these statements
are generic workplace criticisms used to explain many terminations regardless of the
employee’s age. That these comments were not directed at the younger interns does
not suggest they were age-based, but only that Lees did not think these issues
similarly plagued their performance. Nash also suggests he is entitled to a favorable
inference because neither Lees nor Wright immediately denied his allegations of age
discrimination at the termination meeting. The two cases Nash cites to support this
proposition—Baxter v. Palmigiano, 

, 316-20 (1976), and National
Acceptance Co. of America v. Balthalter, 

, 926-30 (7th Cir. 1983)—were
both rooted in Fifth Amendment principles that are not applicable here. Allowing for
any sort of adverse inference would be unsupported by law and seemingly require
employers to risk further escalation of an already tense situation by engaging with a
distressed employee upon termination. We think it unwise to create such a rule.

       Whatever small amount of combined probative value the above-described
evidence has is eroded when we apply two well-established presumptions to the
undisputed facts at hand. First, it is significant that Nash was hired and fired “‘within
a relatively short period of time.’” Arraleh v. County of Ramsey, 

, 976
(8th Cir. 2006) (quoting Herr v. Airborne Freight Corp., 

, 363 (8th Cir.
1997)); accord Haigh v. Gelita USA, Inc., 

, 470 (8th Cir. 2011) (“‘We
have noted it is unlikely a supervisor would hire an older employee and then
discriminate on the basis of age, and such evidence creates a presumption against
discrimination.’” (quoting Fitzgerald v. Action, Inc., 

, 877 (8th Cir.
2008))); Lowe v. J.B. Hunt Transp., Inc., 

, 175 (8th Cir. 1992) (“It is
simply incredible, in light of the weakness of plaintiff’s evidence otherwise, that the
company officials who hired him at age fifty-one had suddenly developed an aversion
to older people less than two years later.”). Second, the fact Lees himself was only
five years younger than Nash when he made the decision both to hire and fire Nash

                                          -9-
also “run[s] counter to any reasonable inference of discrimination based on age.”
Rothmeier v. Inv. Advisers, Inc., 

, 1337 (8th Cir. 1996); see also 

n.3; 

.

       Nash attempts to avoid these presumptions by arguing they do not apply to
MHRA claims, but “[t]he Minnesota Supreme Court has held time and again that
MHRA claims are to be construed in accordance with federal precedent. We see no
reason why the Minnesota Supreme Court would deviate from federal precedent
now.” 

(citation omitted) (applying these presumptions
to both the ADEA and MHRA). Nash also suggests such presumptions are improper
under Tolan v. Cotton, 572 U.S. ____, 

(2014), and 

, but this argument does not move the needle. Those cases merely remind
us that we are not to credit Optomec’s version of disputed facts, see Tolan, 572 U.S.
at ____, 134 S. Ct. at 1868, or treat motions for summary judgment more harshly in
the employment-discrimination context, see 

. See
generally Fed. R. Civ. P. 56(a). Here it is undisputed that Nash was hired to be an
intern (age 54), hired permanently (age 55), and fired (age 55), all by the similarly
aged Lees and all events occurring within less than a year. Looking to these facts and
applying these presumptions does not run contrary to Rule 56, Tolan, or Torgerson.
Cf. Buytendorp v. Extendicare Health Servs., Inc., 

, 836 (8th Cir. 2007)
(noting “[w]e need not ignore undisputed facts” at the summary judgment stage).



III.   CONCLUSION
       We conclude Nash failed to present sufficient evidence to raise a genuine issue
for trial as to whether Optomec discriminated against him on the basis of age.
Therefore, we affirm.
