Item 1.01 Entry into a Material Definitive Agreement

On June 18, 2026, Centrus Energy Corp. (the “Company”) entered into a Seventh Amendment to the Section 382 Rights Agreement (the “Seventh Amendment”), which amends the Section 382 Rights Agreement, dated as of April 6, 2016 (the “Rights Agreement”), by and among the Company and Computershare Trust Company, N.A. and Computershare Inc., as rights agent, as previously amended by (i) the First Amendment to the Rights Agreement dated as of February 14, 2017; (ii) the Second Amendment to the Rights Agreement dated as of April 3, 2019; (iii) the Third Amendment to the Rights Agreement dated as of April 13, 2020; (iv) the Fourth Amendment to the Rights Agreement dated as of June 16, 2021; (v) the Fifth Amendment to the Rights Agreement dated as of June 20, 2023; and (vi) the Sixth Amendment to the Rights Agreement dated as of May 28, 2024. The Seventh Amendment was approved by the Board of Directors of the Company (the “Board”) on March 10, 2026, and approved by the Company’s stockholders at the Company’s annual meeting of the stockholders held on June 18, 2026.

The Seventh Amendment (a) extends the Final Expiration Date (as defined in the Rights Agreement) from June 30, 2026 to June 30, 2029 and (b) increases the purchase price for each one one-thousandth (1/1000th) of a share of the Company’s Series A Participating Cumulative Preferred Stock, par value $1.00 per share, from $160.38 to $1,143.95 in light of the increase in the trading price of the Company’s Class A common stock since the adoption of the Fifth Amendment.

The Seventh Amendment was not adopted as a result of, or in response to, any effort to acquire control of the Company. The Seventh Amendment has been adopted in order to preserve for the Company’s stockholders the long-term value of the Company’s net operating loss carry-forwards for United States federal income tax purposes and other tax benefits.
