Interest on the Senior Notes is payable quarterly in arrears on January 31, April 30, July 31 and October 31 of each year to the holders of record at the close of business on the immediately preceding January 15, April 15, July 15 and October 15, respectively. The Senior Notes are senior unsecured obligations of the Company and rank equal in right of payment with the Company’s existing and future senior unsecured indebtedness. The Senior Notes trade on the Nasdaq Global Select Market under the symbol “GREEL.”
The Company may redeem the Senior Notes for cash in whole or in part at any time (i) on or after October 31, 2023 and prior to October 31, 2024, at a price equal to 102% of their principal amount, plus accrued and unpaid interest to, but excluding, the date of redemption, (ii) on or after October 31, 2024 and prior to October 31, 2025, at a price equal to 101% of their principal amount, plus accrued and unpaid interest to, but excluding, the date of redemption, and (iii) on or after October 31, 2025 and prior to maturity, at a price equal to 100% of their principal amount, plus accrued and unpaid interest to, but excluding, the date of redemption.

During 2025, the Company completed a series of public tender/exchange offers, pursuant to which the Company repurchased $15.0 million in aggregate principal amount of the Senior Notes for a total of $5.7 million in cash and exchanged an additional $5.0 million in aggregate principal amount of the Senior Notes for $2.3 million in aggregate principal amount of the New Notes.
The Company concluded the privately negotiated exchanges and the public tender/exchange offers met the definition of a troubled debt restructuring under ASC 470-60, Troubled Debt Restructurings by Debtors, as the Company was experiencing financial difficulties and the creditors granted a concession. The adjusted carrying value of the Senior Notes and New Notes (collectively the “Notes”) exceeded the undiscounted cash flows of the Notes, and therefore, the Company wrote down the carrying value of the Notes to the undiscounted future cash flows of the Notes and recognized a gain on troubled debt restructuring of $11.9 million for the year ended December 31, 2025. Basic and diluted earnings per share for the year ended December 31, 2025 were increased by $0.78 and $0.77, respectively, as a result of these gains.
During 2025, the Company paid $0.7 million in cash to repurchase an aggregate of $1.1 million principal amount of its Senior Notes in open market transactions. The Company recognized a gain on extinguishment of debt of $0.4 million as a result of such open market repurchases.
Following the conclusion of the privately negotiated exchanges, public tender/exchange offers and open market repurchases, the Company had $36.7 million in aggregate principal amount of the Senior Notes outstanding, along with $3.1 million of capitalized contractual interest payments, and $2.3 million in aggregate principal amount of New Notes outstanding, along with $1.0 million of capitalized contractual interest payments.

The New Notes are senior unsecured obligations of the Company and rank equal in right of payment with the Company’s existing and future senior unsecured indebtedness.

The Company may redeem the New Notes for cash in whole or in part at any time (i) on or after July 31, 2026 and prior to July 31, 2027, at a price equal to 102% of their principal amount, plus accrued and unpaid interest to, but excluding, the date of redemption, (ii) on or after July 31, 2027 and prior to July 31, 2028, at a price equal to 101% of their principal amount, plus accrued and unpaid interest to, but excluding, the date of redemption, and (iii) on or after July 31, 2028 and prior to maturity, at a price equal to 100% of their principal amount, plus accrued and unpaid interest to, but excluding, the date of redemption.

About Debt Disclosures

Debt disclosures detail a company's borrowing structure — the types of instruments, interest rates, maturity schedule, and covenant restrictions that define its financial obligations and flexibility. This section is essential for assessing refinancing risk, interest rate exposure, and the margin of safety against financial distress.

Key signals: the maturity schedule reveals concentration risk — large maturities within 1-2 years during tight credit markets can force dilutive refinancing or asset sales. Compare the fair value of debt against carrying amount to gauge whether the market views the company's credit risk differently than the balance sheet suggests. Watch covenant compliance disclosures for tightening cushions, especially leverage and interest coverage ratios. Variable-rate debt exposure quantifies sensitivity to interest rate changes. Secured versus unsecured mix affects recovery rates and future borrowing capacity. Compare net debt-to-EBITDA against industry peers and covenant limits to assess financial health.
