(a) During 2020, Griffon issued, at par, $1,000,000 of 5.75% Senior Notes due 2028 (the “Senior Notes”). Proceeds from the Senior Notes were used to redeem $1,000,000 of 5.25% Senior Notes due in 2022. In connection with the issuance and exchange of the Senior Notes, Griffon capitalized $16,448 of underwriting fees and other expenses incurred, which is being amortized over the term of such notes. During 2022, Griffon purchased $25,225 of Senior Notes in the open market at a weighted average discount of 91.82% of par, or $23,161. As of June 30, 2026, outstanding Senior Notes due totaled $974,775; interest is payable semi-annually on March 1 and September 1.

The Senior Notes are senior unsecured obligations of Griffon guaranteed by certain domestic subsidiaries, and subject to certain covenants, limitations and restrictions. The Senior Notes were registered under the Securities Act of 1933, as amended (the "Securities Act") via an exchange offer. The fair value of the Senior Notes approximated $972,338 on June 30, 2026 based upon quoted market prices (Level 1 inputs). At June 30, 2026, $3,366 of underwriting fees and other expenses incurred remained to be amortized.

(b) On January 24, 2022, Griffon amended and restated its Credit Agreement (the "Credit Agreement") to provide for a new $800,000 Term Loan B facility, due January 24, 2029, in addition to the revolving credit facility (the "Revolver") provided for under the Credit Agreement. The Term Loan B facility was issued at 99.75% of par value. Additionally, during 2024 Griffon further amended its Credit Agreement to favorably reprice the Term Loan B facility. The amendment reduced the margin above Secured Overnight Financing Rate ("SOFR") by 0.25%, eliminated the credit spread adjustment and reduced the SOFR floor from 0.50% to 0%.

The Term Loan B bears interest at the Term SOFR rate plus a spread of 2.00% (5.66% as of June 30, 2026). The Term Loan B facility continues to require nominal quarterly principal payments of $2,000, potential additional annual principal payments based on a percentage of excess cash flow and certain secured leverage thresholds and a final balloon payment due at maturity. Term Loan B borrowings may generally be repaid without penalty. Once repaid, Term Loan B borrowings may not be reborrowed. The Term Loan B facility is subject to the same affirmative and negative covenants that apply to the Revolver (as described below), but is not subject to any financial maintenance covenants. Term Loan B borrowings are secured by the same collateral that secures borrowings under the Revolver, on an equal and ratable basis. The fair value of the Term Loan B facility approximated $285,000 on June 30, 2026 based upon quoted market prices (Level 1 inputs).

During the nine months ended June 30, 2026, Griffon prepaid $158,000 of the aggregate principal amount outstanding under the Term Loan B facility, in addition to the required principal payments of $6,000. In connection with this prepayment Griffon recognized a $1,389 loss on debt extinguishment, $1,250 related to the write-off of underwriting fees and other expenses and $138 of the original issue discount. Since the inception of the loan, Griffon has prepaid $483,000 aggregate principal amount of the Term Loan B, which permanently reduced the outstanding balance. As of June 30, 2026, the Term Loan B outstanding balance was $285,000. At June 30, 2026, remaining capitalized fees and original issue discount were $2,086 and $230, respectively.

Subsequent to June 30, 2026, Griffon voluntarily repaid in full the outstanding principal balance under the Term Loan B of $285,000 and satisfied all of the Company's outstanding obligations under the Term Loan B credit agreement. In connection with this prepayment, after recording the July monthly amortization of both the capitalized fees and original issue discount, Griffon wrote-off the remaining capitalized fees and original issue discount of $2,018 and $223, respectively.

On August 1, 2023, Griffon amended and restated the Credit Agreement to increase the maximum borrowing availability under the Revolver from $400,000 to $500,000 and extend the maturity date of the Revolver from March 22, 2025 to August 1, 2028. In the event the Senior Notes are not repaid, refinanced, or replaced prior to December 1, 2027, the Revolver will mature on December 1, 2027. The amendment also modified certain other provisions of the Credit Agreement, including increasing the letter of credit sub-facility under the Revolver from $100,000 to $125,000 and increasing the customary accordion feature from a minimum of $375,000 to a minimum of $500,000. The Revolver also includes a multi-currency sub-facility of $200,000.

Borrowings under the Revolver may be repaid and re-borrowed at any time. Interest is payable on borrowings at either a SOFR, Sterling Overnight Index Average ("SONIA") or base rate benchmark rate, plus an applicable margin, which

adjusts based on financial performance. Griffon's SOFR loans accrue interest at Term SOFR plus a credit adjustment spread and a margin of 1.75% (5.51% at June 30, 2026); SONIA loans accrue interest at SONIA Base Rate plus a credit adjustment spread and a margin of 1.75% (5.51% at June 30, 2026); and base rate loans accrue interest at prime rate plus a margin of 0.75% (7.50% at June 30, 2026).

At June 30, 2026, under the Credit Agreement, there was $15,000 in outstanding borrowings on the Revolver; outstanding standby letters of credit were $12,652; and $472,348 was available, subject to certain loan covenants, for borrowing at that date.

The Revolver has certain financial maintenance tests including a maximum total leverage ratio, a maximum senior secured leverage ratio and a minimum interest coverage ratio, as well as customary affirmative and negative covenants and events of default. The negative covenants place limits on Griffon's ability to, among other things, incur indebtedness, incur liens, and make restricted payments and investments. Both the Revolver and Term Loan B borrowings under the Credit Agreement are guaranteed by Griffon’s material domestic subsidiaries and are secured, on a first priority basis, by substantially all domestic assets of the Company and the guarantors.
