The aggregate maturities of long-term debt for the five years subsequent to May 31, 2021 are as follows: fiscal 2022 — $1.4 million; fiscal 2023 — $701.5 million; fiscal 2024 — $340.2 million; fiscal 2025 — $0.5 million; fiscal 2026 — $0.3 million and thereafter $1,350.9 million. Additionally, at May 31, 2021, we had unused lines of credit totaling $1.2 billion.

Our available liquidity, including our cash and cash equivalents and amounts available under our committed credit facilities, stood at $1,457.1 million at May 31, 2021. Our debt-to-capital ratio was 57.8% at May 31, 2021, compared with 66.8% at May 31, 2020.

During the quarter ended November 30, 2018, we replaced our previous $800.0 million revolving credit agreement, which was set to expire on December 5, 2019, with a $1.3 billion unsecured syndicated revolving credit facility (the “Revolving Credit Facility”), which expires on October 31, 2023. The Revolving Credit Facility includes sublimits for the issuance of swingline loans, which are comparatively short-term loans used for working capital purposes and letters of credit. The aggregate maximum principal amount of the commitments under the Revolving Credit Facility may be expanded upon our request, subject to certain conditions, up to $1.5 billion. The Revolving Credit Facility is available to refinance existing indebtedness, to finance working capital and capital expenditures, and for general corporate purposes.

The Revolving Credit Facility requires us to comply with various customary affirmative and negative covenants, including a leverage covenant (i.e., Net Leverage Ratio) and interest coverage ratio, which are calculated in accordance with the terms as defined by the Revolving Credit Facility. On April 30, 2020, we amended both our Revolving Credit Facility and the New Credit Facility (see “Term Loan Facility Credit Agreement” section below for further details) to allow the maximum permitted Net Leverage Ratio to be increased from 3.75 to 1.0 to 4.25 to 1.0 for four consecutive fiscal quarters following notice to the Administrative Agent on or before June 30, 2021 and the payment of a ten basis point fee (“Increased Net Leverage Ratio Period”). Such increase is in addition to any increase requested by us in the maximum permitted Net Leverage Ratio following a Material Acquisition (any acquisition for which the aggregate consideration is $100.0 million or greater). During an Increased Net Leverage Ratio Period, the Euro-Rate Spread on loans under the Revolving Credit Facility shall be increased to 1.75% and the Base Rate Spread shall be 0.75% until the first day of the month following the Increased Net Leverage Ratio Period; provided, however, if at any time during an Increased Net Leverage Ratio, all three rating agencies rate the Company as non-investment grade, the Euro-Rate Spread shall be 2.0% and the Base Rate Spread shall be 1.0% in each case until earlier of the first day of the month after the Increased Net Leverage Ratio or the date on which at least one rating agency rates us as investment grade. As of May 31, 2021, we have not provided any notice to the Administrative Agent to trigger this provision. Furthermore, no such notice was provided, subsequent to the balance sheet date, on or before June 30, 2021, and as such, this provision has lapsed.

Under the terms of the leverage covenant, we may not permit our leverage ratio for total indebtedness to consolidated EBITDA for the four most recent fiscal quarters to exceed 3.75 to 1.0. During certain periods and per the terms of the Revolving Credit Facility, this ratio may be increased to 4.25 to 1.0 in connection with certain “material acquisitions,” or under the Increased Net Leverage Ratio Period. The acquisition of Ali Industries, LLC which occurred on September 1, 2020 and qualified as a “material acquisition,” which enables us to request an increase in the maximum permitted Net Leverage Ratio covenant. We provided such notice to our Administrative Agent during our second quarter of fiscal 2021, and therefore, our Net Leverage Ratio covenant has been increased to 4.25 to 1.0 through August 31, 2021. The minimum required consolidated interest coverage ratio for EBITDA to interest expense is 3.50 to 1. The interest coverage ratio is calculated at the end of each fiscal quarter for the four fiscal quarters then ended using EBITDA as defined in the Revolving Credit Facility.

As of May 31, 2021, we were in compliance with all financial covenants contained in our Revolving Credit Facility, including the leverage and interest coverage ratio covenants. At that date, our leverage ratio was 2.17 to 1, while our interest coverage ratio was 12.24 to 1. Our available liquidity under our Revolving Credit Facility stood at $960.4 million at May 31, 2021.

Our access to funds under our Revolving Credit Facility is dependent on the ability of the financial institutions that are parties to the Revolving Credit Facility to meet their funding commitments. Those financial institutions may not be able to meet their funding commitments if they experience shortages of capital and liquidity or if they experience excessive volumes of borrowing requests within a short period of time. Moreover, the obligations of the financial institutions under our Revolving Credit Facility are several and not joint and, as a result, a funding default by one or more institutions does not need to be made up by the others.

On May 9, 2014, we entered into a $200.0 million accounts receivable securitization facility (the “AR Program”) which was subsequently amended on May 22, 2020 to a maximum availability of $250.0 million and an extended facility termination date of May 21, 2021. On March 18, 2021, we amended the AR Program to a maximum availability of $250 million during all borrowing periods

and an extended facility termination date of May 21, 2024. The AR Program was entered into pursuant to (1) a second amended and restated receivables sales agreement, dated as of May 9, 2014, and subsequently amended on August 29, 2014; November 3, 2015; December 31, 2016; March 31, 2017; and June 5, 2020 (the “Sale Agreement”), among certain of our subsidiaries (the “Originators”), and RPM Funding Corporation, a special purpose entity (the “SPE”) whose voting interests are wholly owned by us, and (2) an amended and restated receivables purchase agreement, dated as of May 9, 2014 and subsequently amended on February 25, 2015 and May 2, 2017, May 22, 2020 and March 18, 2021 (the “Purchase Agreement”), among the SPE, certain purchasers from time to time party thereto (the “Purchasers”), and PNC Bank, National Association as administrative agent.

Under the Sale Agreement, the Originators may, during the term thereof, sell specified accounts receivable to the SPE, which may in turn, pursuant to the Purchase Agreement, transfer an undivided interest in such accounts receivable to the Purchasers. Once transferred to the SPE, such receivables are owned in their entirety by the SPE and are not available to satisfy claims of our creditors or creditors of the originating subsidiaries until the obligations owing to the participating banks have been paid in full. We indirectly hold a 100% economic interest in the SPE and will, along with our subsidiaries, receive the economic benefit of the AR Program. The transactions contemplated by the AR Program do not constitute a form of off-balance sheet financing and will be fully reflected in our financial statements.

The maximum availability under the AR Program is $250.0 million. Availability is further subject to changes in the credit ratings of our customers, customer concentration levels or certain characteristics of the accounts receivable being transferred and, therefore, at certain times, we may not be able to fully access the $250.0 million of funding available under the AR Program. As of May 31, 2021, there was no outstanding balance under the AR Program, which compares with the maximum availability on that date of $250.0 million.

The interest rate under the Purchase Agreement is based on the Alternate Base Rate, LIBOR Market Index Rate, one-month LIBOR or LIBOR for a specified tranche period, as selected by us, plus in each case, a margin of 0.85%. In addition, as set forth in an Amended and Restated Fee Letter, dated March 18, 2021 (the “Fee Letter”), the SPE is obligated to pay a monthly unused commitment fee to the Purchasers based on the daily amount of unused commitments under the Agreement, which ranges from 0.30% to 0.50% based on usage. The AR Program contains various customary affirmative and negative covenants and also contains customary default and termination provisions.

Our failure to comply with the covenants described above and other covenants contained in the Revolving Credit Facility section above could result in an event of default under that agreement, entitling the lenders to, among other things, declare the entire amount outstanding under the Revolving Credit Facility to be due and payable. The instruments governing our other outstanding indebtedness generally include cross-default provisions that provide that, under certain circumstances, an event of default that results in acceleration of our indebtedness under the Revolving Credit Facility will entitle the holders of such other indebtedness to declare amounts outstanding immediately due and payable.

On October 23, 2012, we sold $300 million aggregated principal amount of 3.45% Notes due 2022. The net proceeds of $297.7 million from this offering were used to repay short-term borrowings outstanding under our revolving credit facility.

On February 21, 2020, we and our subsidiary, RPM Europe Holdco B.V. (formerly “RPM New Horizons Netherlands, B.V”). (the “Foreign Borrower”), entered into an unsecured syndicated term loan facility credit agreement (the “New Credit Facility”) with the lenders party thereto and PNC Bank, National Association, as administrative agent for the lenders. The New Credit Facility provides for a $300 million term loan to us and a $100 million term loan to the Foreign Borrower (together, the “Term Loans”), each of which was fully advanced on the closing date. The Term Loans mature on February 21, 2023, with no scheduled amortization before that date, and the Term Loans may be prepaid at any time without penalty or premium. We agreed to guarantee all obligations of the Foreign Borrower under the New Credit Facility. The proceeds of the Term Loans were used to repay a portion of the outstanding borrowings under our revolving credit facility. During fiscal 2021, the New Credit Facility was amended to replace RPM New Horizons Netherlands, B.V. with RPM Europe Holdco B.V.

The Term Loans will bear interest at either the base rate or the Eurodollar Rate, at our option, plus a spread determined by our debt rating. We, and the Foreign Borrower, have entered into multicurrency floating to fixed interest rate swap agreements that effectively fix interest payment obligations on the entire principal amount of the Term Loans through their maturity at (a) 0.612% per annum on our Term Loan, and (b) 0.558% per annum on the Foreign Borrower’s Term Loan.

The New Credit Facility contains customary covenants, including but not limited to, limitations on our ability, and in certain instances, our subsidiaries’ ability, to incur liens, make certain investments, or sell or transfer assets. Additionally, we may not permit (i) our consolidated interest coverage ratio to be less than 3.5 to 1.0, or (ii) our leverage ratio (defined as the ratio of total indebtedness, less unencumbered cash and cash equivalents in excess of $50 million, to consolidated EBITDA for the four most recent fiscal quarters) to exceed 3.75 to 1.0. Upon notification to the lenders, however, the maximum permitted leverage ratio can be relaxed to 4.25 to 1.0 for a one-year period in connection with certain material acquisitions. In addition, the agreement was amended on April 30, 2020 to allow the maximum permitted Net Leverage Ratio to be increased to 4.25 to 1 during certain periods (refer to the “Revolving Credit Agreement”). As noted in the “Revolving Credit Agreement” above, we provided notice to our Administrative Agent during our second quarter of fiscal 2021, and therefore, our Net Leverage Ratio covenant has been increased to 4.25 to 1.0 through August 31, 2021. The covenants contained in the New Credit Facility are substantially similar to those contained in our Revolving Credit Facility. See “Revolving Credit Agreement” above for details on our compliance with all significant financial covenants at May 31, 2021.

On March 2, 2017, we issued $50.0 million aggregate principal amount of 5.250% Notes due 2045 (the “2045 Notes”) and $400.0 million aggregate principal amount of 3.750% Notes due 2027 (the “2027 Notes”). The 2045 Notes are a further issuance of the $250 million aggregate principal amount of 5.250% Notes due 2045 initially issued by us on May 29, 2015. Interest on the 2045 Notes is payable semiannually in arrears on June 1st and December 1st of each year at a rate of 5.250% per year. The 2045 Notes mature on June 1, 2045. Interest on the 2027 Notes is payable semiannually in arrears on March 15th and September 15th of each year, at a rate of 3.750% per year. The 2027 Notes mature on March 15, 2027. The indenture governing this indebtedness includes cross-acceleration provisions. Under certain circumstances, where an event of default under our other instruments results in acceleration of the indebtedness under such instruments, holders of the indebtedness under the indenture are entitled to declare amounts outstanding immediately due and payable.

On February 27, 2019, we closed an offering for $350.0 million aggregate principal amount of 4.550% Notes due 2029 (the “2029 Notes”). The proceeds from the 2029 Notes were used to repay a portion of the outstanding borrowings under our revolving credit facility and for general corporate purposes. Interest on the 2029 Notes accrues from February 27, 2019 and is payable semiannually in arrears on March 1^st and September 1^st of each year, beginning September 1, 2019, at a rate of 4.550% per year. The 2029 Notes mature on March 1, 2029. The indenture governing this indebtedness includes cross-acceleration provisions. Under certain circumstances, where an event of default under our other instruments results in acceleration of the indebtedness under such instruments, holders of the indebtedness under the indenture are entitled to declare amounts outstanding immediately due and payable.

On December 20, 2017, we closed an offering for $300.0 million aggregate principal amount of 4.250% Notes due 2048 (the “2048 Notes”). The proceeds from the 2048 Notes were used to repay $250.0 million in principal amount of unsecured 6.50% senior notes due February 15, 2018, and for general corporate purposes. Interest on the 2048 Notes accrues from December 20, 2017 and is payable semiannually in arrears on January 15^th and July 15^th of each year, beginning July 15, 2018, at a rate of 4.250% per year. The 2048 Notes mature on January 15, 2048. The indenture governing this indebtedness includes cross-acceleration provisions. Under certain circumstances, where an event of default under our other instruments results in acceleration of the indebtedness under such instruments, holders of the indebtedness under the indenture are entitled to declare amounts outstanding immediately due and payable.
