As of August 31, 2025, the Company held borrowings under two separate agreements as detailed below.

Note Purchase and Private Shelf Agreement

The Company holds borrowings under its Note Purchase and Private Shelf Agreement, as amended (the “Note Agreement”) by and among the Company, PGIM, Inc. (“Prudential”), and certain affiliates and managed accounts of Prudential (the “Note Purchasers”). As of August 31, 2025, the Company had outstanding balances on its series A, B and C notes issued under this Note Agreement.

The Note Agreement was most recently amended on April 30, 2024 (the “Fourth Amendment”). The Fourth Amendment permitted the Company to enter into an amendment to its revolving credit agreement with Bank of America, N.A. and also included certain conforming amendments to the credit agreement, including the revision of financial and restrictive covenants.

Credit Agreement

On April 30, 2024, the Company and certain subsidiaries of the Company, entered into a Second Amended and Restated Credit Agreement with Bank of America, N.A. (the “Credit Agreement”). The Credit Agreement modified certain terms and conditions of the Company’s previous Amended and Restated Agreement dated March 16, 2020 (as amended on September 30, 2020, and November 29, 2021), and extended the maturity date for the revolving credit facility from

September 30, 2025 to April 30, 2029. Borrowings under the Credit Agreement will be used for the Company’s various operating, investing and financing needs.

The Company’s Credit Agreement with Bank of America, N.A. consists of a revolving commitment for borrowing by the Company up to $125.0 million and with a sublimit from $95.0 million for WD-40 Company Limited, a wholly owned operating subsidiary of the Company for Europe, India, the Middle East and Africa. The Company’s index rate under the Credit Agreement for U.S. Dollar borrowings is the Secured Overnight Financing Rate as administered by the Federal Reserve Bank of New York.

Short-term and long-term borrowings under the Company’s Credit Agreement and Note Agreement consisted of the following (in thousands):

(1)The Company has the ability to refinance any draw under the line of credit with successive short-term borrowings through the maturity date. Outstanding draws for which management has the ability and intent to refinance with successive short-term borrowings for a period of at least twelve months are classified as long-term. As of August 31, 2025, $21.0 million of this facility was classified as long-term and was entirely denominated in Euros. As of August 31, 2024, $20.0 million of this facility was classified as long-term and was denominated in Euros and Pounds Sterling; $7.8 million was classified as short-term and was denominated in U.S. Dollars. Euro and Pound Sterling denominated draws fluctuate in U.S. Dollars from period to period due to changes in foreign currency exchange rates.

(2)Principal payments are required semi-annually in May and November of each year in equal installments of $0.4 million through May 15, 2032, resulting in $0.8 million classified as short-term. The remaining outstanding principal in the amount of $8.4 million will become due on November 15, 2032.

(3)Interest on notes is payable semi-annually in May and November of each year with no principal due until the maturity date.

Both the Note Agreement and the Credit Agreement contain representations, warranties, events of default and remedies, as well as affirmative, negative and other financial covenants customary for these types of agreements. These covenants include, among other things, certain limitations on the ability of the Company and its subsidiaries to incur indebtedness, create liens, dispose of assets, make investments, declare, make or incur obligations to make certain restricted payments, including payments for the repurchase of the Company’s capital stock and enter into certain merger or consolidation transactions. The Credit Agreement includes, among other limitations on indebtedness, a $125.0 million limit on other unsecured indebtedness.

Each agreement also includes a most favored lender provision which requires that any time any other lender has the benefit of one or more financial or operational covenants that is different than, or similar to, but more restrictive than those contained in its own agreement, those covenants shall be immediately and automatically incorporated by reference to the other lender’s agreement. Both the Note Agreement and the Credit Agreement require the Company to adhere to the same financial covenants. For the financial covenants, the definition of consolidated EBITDA includes the add back of non-cash stock-based compensation to consolidated net income when arriving at consolidated EBITDA. The terms of the financial covenants are as follows:

•The consolidated leverage ratio cannot be greater than three and a half to one. The consolidated leverage ratio means, as of any date of determination, the ratio of (a) consolidated funded indebtedness as of such date to (b) consolidated EBITDA for the most recently completed four fiscal quarters.

•The consolidated interest coverage ratio cannot be less than three to one. The consolidated interest coverage ratio means, as of any date of determination, the ratio of (a) consolidated EBITDA for the most recently completed four fiscal quarters to (b) consolidated interest charges for the most recently completed four fiscal quarters

As of August 31, 2025, the Company was in compliance with all debt covenants under both the Note Agreement and the Credit Agreement.
