UNITED STATES DISTRICT COURT EASTERN DISTRICT OF MICHIGAN SOUTHERN DIVISION ANGELA STINGLEY,

Plaintiff, Case Number 24-12114 v. Honorable David M. Lawson

HOLCIM (U.S.) INC.,

Defendant. ________________________________________/

OPINION AND ORDER GRANTING DEFENDANT’S MOTION FOR SUMMARY JUDGMENT AND DISMISSING AMENDED COMPLAINT WITH PREJUDICE Plaintiff Angela Stingley was hired by defendant Holcim (U.S.) as a senior tax analyst in May 2023. She was fired in April 2024 allegedly for performance issues. Stingley, however, says that race and gender played a role in the decision to terminate her, and she filed a complaint (later amended) alleging unlawful discrimination and retaliation under 42 U.S.C. § 1981, Title VII of the Civil Rights Act of 1964, and Michigan’s Elliott-Larsen Civil Rights Act. After the discovery period closed, the defendant filed the present motion for summary judgment. The Court heard oral argument on August 13, 2026. The plaintiff has offered evidence to establish a prima facie case, but because she has not offered sufficient evidence to create a material fact question about whether the defendant’s lawful reasons for firing her were a pretext for discrimination or retaliation, the Court will grant the motion and dismiss the case. I. The parties agree on the basic chronology and context of this employment dispute. Defendant Holcim (U.S.) Inc. (a/k/a “Amrize”) states on its public website that it is “a global leader in innovative and sustainable building solutions,” engaged in the business of “enabling greener cities, smarter infrastructure and improving living standards around the world,” with their primary services being the delivery of designs and building materials for large scale commercial and infrastructure projects, both in the United States and in other global markets. See Holcim (U.S.) / Amrize Company Profile, https://amrize.com/us/en/amrize-homepage.html (last visited Sept. 15, 2026).

Plaintiff Angela Stingley is a 56-year-old African-American woman. She was hired by the defendant as a Senior Tax Analyst on May 22, 2023 and began work on June 20, 2023, reporting to Eric Beaupre, Holcim’s Senior Manager of US Indirect Tax. Her duties included reviewing corporate tax returns, assessing the taxability of “various projects” undertaken by the company, and responding to queries submitted via email to a departmental “Tax Mailbox.” Initially, Beaupre assigned Stingley to “use tax” determinations, which involved assessing whether items bought by the company were subject to local use taxes (i.e., sales tax). The parties dispute whether the plaintiff performed these and other duties in a satisfactory manner. Her performance record is discussed later. What is not disputed, however, is that after Stingley filed a complaint with the human resources department about Beaupre’s conduct in January 2024, and after she received an

unfavorable performance review from Beaupre in that same month, Vickie Hurst, Holcim’s Head of Indirect Tax, took over as Stingley’s supervisor. On February 29, 2024, Hurst put Stingley on a Performance Improvement Plan (“PIP”), which stated that Holcim would consider terminating her employment if Stingley failed to improve her work performance to address deficiencies listed in the PIP within 30 days. Letter dated February 29, 2024, ECF No. 18-12, PageID.439-40. Hurst attested that Stingley “failed to show significant improvement on the performance issues identified in her PIP,” and that as a result Hurst “made the decision to terminate Ms. Stingley’s employment . . . effective April 5, 2024.” Vickie Hurst decl., ECF No. 18-21, PageID.495. When she was hired, the plaintiff executed a “Confidentiality Agreement,” which provided that she “[understood] and agree[d] that [she] may only use Confidential Information (defined below) for purposes of carrying out [her] job duties for Holcim, and . . . may not otherwise make use of or disclose any such information during or after termination of [] employment with Holcim

without the express written consent of the General Counsel of Holcim.” Confidentiality Agreement, ECF No. 18-5, PageID.405. “Confidential Information” is defined in the agreement to “include[] all of the Company’s trade secrets it currently has or may acquire, confidential and proprietary information, and all other non-public information and data of or about the Company and its business, written or otherwise, including, but not limited to . . . any non-public prices, discounts, commissions, costs, purchasing information, supplier or vendor information, earnings . . . business plans . . . [and] other business arrangements, as well as . . . work product [the employee] create[s] in rendering services for the Company.” Ibid. Stingley further acknowledged that “[a]ny documents containing Confidential Information, whether prepared by [her] or furnished by Holcim, must be returned to Holcim at the Company’s request or no later than 24 hours after

termination of [her] employment,” and that she “may not make or retain copies of such documents.” Ibid. However, the agreement also states: “Nothing in this Agreement is intended to prohibit [the employee] from sharing Confidential Information if required by law or administrative agency process, or to prohibit [her] from engaging in protected concerted activity.” Id. at 406. The foregoing facts are uncontested. The parties do not see eye to eye, however, on some of the other facts in the record. The defendant highlights evidence indicating that the plaintiff was not performing up to expectations. For her part, the plaintiff testified at her deposition that the first meeting she had with Beaupre in August 2023 did not go well. She admitted that when assigned to perform use tax assessments, she “would review what the previous [tax analyst] did for that same purchase and use that assessment,” and Beaupre “immediately said no, you can't do that,” and “[y]ou need to do your due diligence because we found out that using information another tax employee used is hurting us on audits.” Angela Stingley dep., ECF No. 18-2, PageID.367. Stingley agreed that

“[j]ust copying what someone did [in] a prior month isn’t acceptable” when making use tax determinations. Id. at 369. But Stingley testified that during the meeting Beaupre went on to “attack her character,” by saying, “You are a senior analyst with all this experience and you’re telling me that you don’t know how to do this. You should be able to do this. You are a senior analyst.” Id. at 371. In response to Beaupre’s criticism, the plaintiff rose from her seat, “looked at the door,” and gestured indicating that she “want[ed] to get out of [the office],” and then left the room and returned to her desk. Id. at 371-72. She was upset and felt she had been treated unfairly by Beaupre because she had only been with the company for a few weeks and he had “ignored [her] for the first few weeks [she] was there,” then criticized her competence “as if [she] had worked for the company for a year” and had experience and familiarity with the business on par
