2021 Bond Issuance

On April 15, 2021, on behalf of Gevo NW Iowa RNG, LLC, the Iowa Finance Authority ("the "Authority") issued $68,155,000 of its non-recourse Solid Waste Facility Revenue Bonds (Gevo NW Iowa RNG, LLC Renewable Natural Gas Project), Series 2021 (Green Bonds) (the "2021 Bonds") for NW Iowa RNG. The bond proceeds are being used as a source of construction financing alongside equity from the Company. The bonds were issued under a Trust Indenture dated as of April 1, 2021 (the "Indenture") between the Authority and Citibank, N.A. as trustee (the "Trustee"). The 2021 Bonds mature April 1, 2042. They initially bear interest at 1.50% per annum during the Initial Term Rate Period, (as defined in the Indenture) payable semi-annually on January 1 and July 1 of each year. The bonds are supported by a $71.2 million irrevocable direct pay letter of credit (the "Letter of Credit"), which expires April 4, 2024 (unless terminated earlier), and was issued by Citibank, N.A. The Trustee will draw sufficient amounts on the Letter of Credit to pay the principal and interest until the first mandatory tender date of April 1, 2024. The bonds are callable and re-marketable on or after October 1, 2022. If the bonds have not been called and re-marketed by the first mandatory tender date the Trustee may draw on the Letter of Credit to repay the bonds in their entirety at the purchase price. Gevo deposited $71.2 million with Citibank, N.A. as restricted cash to secure any amounts drawn under the Letter of Credit. As of March 31, 2022, no amounts have been drawn under the Letter of Credit.

Gevo anticipates re-marketing the 2021 Bonds in the fall of 2022 under revised terms that will include a long-term maturity date and be non-recourse to Gevo. Upon a successful remarketing, Gevo anticipates that the Letter of Credit, the associated reimbursement agreement and the associated pledge of cash will be terminated, with a concurrent release of the restricted cash securing the Letter of Credit.

The 2021 Bonds were issued at a premium of $0.8 million, and debt issuance costs were $3.0 million. The bond debt is classified as long-term debt and is presented net of the premium and issuance costs, which are being amortized over the life of the bonds using the interest method. As of March 31, 2022, the premium balance, and debt issuance cost net of amortization were $0.6 million and $2.1 million, respectively.

Restricted cash and cash equivalents. The Company’s restricted cash and restricted cash equivalents consists of unused proceeds from the issuance of the 2021 Bonds, and are restricted for the purpose of constructing NW Iowa RNG projects as well as amounts pledged and assigned to Citibank, N.A. in its capacity as provider of the Letter of Credit as collateral for the reimbursement obligations of Gevo.

The proceeds from issuance of the 2021 Bonds are maintained by the Trustee under the Indenture and are released to the Company only to pay costs of the construction of NW Iowa RNG. The Company has used $53.0 million for the project. As of March 31, 2022, unused bond proceeds of $15.2 million are included in restricted cash classified as current since the proceeds will be distributed within 12 months. We expect all construction invoices will be received and paid, and the remaining unused bond proceeds will be released to reimburse Gevo by the end of the second quarter of 2022.

As of March 31, 2022, $71.2 million is held in restricted cash as collateral for the Letter of Credit. The Company is entitled to receive interest income on the restricted cash.
