~~Amendment~~On toApril 8, ~~Revolving~~2026, ~~Credit~~the ~~Facility~~Company issued a press release announcing its third quarter results, which provided detail not included in previously issued reports. A copy of the press release is furnished with this Current Report on Form 8-K as Exhibit 99.1.

OnItem ~~February 27, 2026, RPM International Inc~~9.01 (the “Company”) and certain of its subsidiaries amended the Company’s revolving credit facility by entering into a Seventh Amendment to Credit Agreement (the “Credit Agreement Amendment”) with the lenders named therein (the “Revolving Credit Facility Lenders”) and PNC Bank, National Association, as administrative agent for the Revolving Credit Facility Lenders, which amends the Credit Agreement dated as of October 31, 2018 (as amended, the “Credit Agreement”)Exhibits.

The Credit Agreement Amendment extends the term of the Credit Agreement for five years, until February 27, 2031. Pursuant to the Credit Agreement Amendment, U.S. Dollar revolving loans will bear interest at either the base rate or term SOFR rate (or in the case of swingline loans, the daily simple SOFR rate), at the Company’s option, plus a spread determined by the Company’s debt rating. Foreign currency loans will bear interest at either a daily simple RFR rate, term RFR rate or Eurocurrency rate plus, in each case, a similar spread. At the closing of the Credit Agreement Amendment, the applicable spread for (a) base rate loans was 0.0% per annum, with possible future spreads ranging from 0.0% to 0.30% per annum, and (b) term SOFR rate, daily simple SOFR rate, daily simple RFR rate, term RFR rate and Eurocurrency rate loans was 1.00% per annum, with possible future spreads ranging from 0.785% to 1.30% per annum. The Credit Agreement Amendment also provides for a facility fee based on the aggregate outstanding commitments at an initial rate of 0.125% per annum, which, like the interest rate spreads, is subject to adjustment thereafter based on the Company’s debt rating, with possible future rates ranging from 0.09% to 0.20% per annum.


Exhibit Number		Description

99.1		Press Release of the Company, dated April 8, 2026, announcing the Company’s third quarter results.

104		Cover Page Interactive Data File (embedded within the Inline XBRL document)

The Credit Agreement contains customary covenants, including but not limited to, limitations on the Company’s ability, and in certain instances, its subsidiaries’ ability, to incur liens or sell or transfer all or substantially all of its assets. Additionally, the Company may not permit its leverage ratio (defined as the ratio of consolidated total indebtedness (less unencumbered cash and cash equivalents) to consolidated EBITDA for the four most recent fiscal quarters) as at the end of any fiscal quarter to exceed 3.75 to 1.0. The Credit Agreement Amendment eliminated the interest coverage ratio financial covenant.

Upon the occurrence of certain events of default, our obligations under the Credit Agreement may be accelerated. Such events of default include payment defaults under the Credit Agreement, covenant defaults, payment defaults under other material indebtedness (other than under the Credit Agreement), certain ERISA defaults, change of control and other customary events of default.

The description contained herein of the Credit Agreement Amendment is qualified in its entirety by reference to the full text of the Credit Agreement Amendment, which will be filed as an exhibit to the Company’s Quarterly Report on Form 10-Q for the quarterly period ending February 28, 2026, and is incorporated herein by reference.
