Kyivstar Group Ltd. reported that it issued a press release on May 28, 2026, and furnished that announcement to the SEC on Form 6-K the same day. The filing identifies the release as Exhibit 99.1, dated May 28, 2026. The provided filing text does not include the body of the press release, so the specific corporate development announced in the release cannot be confirmed from the document text supplied. The HTML filename references a “CFO transition,” but the filing itself does not provide the details of any executive change, effective date, successor, resignation, appointment, or related employment terms. The report was signed on behalf of Kyivstar Group Ltd. by Boris Dolgushin, who is listed as Chief Financial Officer. Kyivstar’s principal executive office is identified as being in the Dubai International Financial Centre in the United Arab Emirates. No securities transactions, insider share purchases or sales, option exercises, vesting events, share counts, prices, transaction codes, or post-transaction ownership amounts are reported in the text provided. The significance of the filing is that Kyivstar, a foreign private issuer reporting on Form 20-F, used Form 6-K to furnish a contemporaneous corporate press release to U.S. investors, but the substantive announcement is contained in Exhibit 99.1, which is not included in the supplied document text.
