Note 14. Long-Term Debt

3.00% Senior Convertible Notes due 2025

On June 2, 2020, we issued $175.0 million in aggregate principal amount of 3.00% Convertible Senior Notes due 2025 (the “Notes”), including the initial purchasers’ exercise in full of their option to purchase an additional $25.0 million principal amount of the Notes, between us and U.S. Bank National Association, as trustee (the “Trustee”), in a private offering to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended. The net proceeds from the issuance of the Notes were $169.8 million after deducting transaction costs.

The Notes are senior, unsecured obligations and will accrue interest payable semiannually in arrears on June 1 and December 1 of each year at a rate of 3.00% per year. The Notes will mature on June 1, 2025, unless earlier converted, redeemed, or repurchased. The Notes are convertible into cash, shares of our common stock or a combination of cash and shares of our common stock, at our election. As of December 31, 2022, the if-converted value of the Notes was $88.3 million less than its principal amount.

A holder of Notes may convert all or any portion of its Notes at its option at any time prior to the close of business on the business day immediately preceding March 1, 2025 only under the following circumstances: (1) during any fiscal quarter commencing after the fiscal quarter ending on September 30, 2020 (and only during such fiscal quarter), if the last reported sale price of our common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding fiscal quarter is greater than or equal to 130% of the conversion price on each applicable trading day; (2) during the five business day period after any ten consecutive trading day period (the “measurement period”) in which the “trading price” per $1,000 principal amount of Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of our common stock and the conversion rate on each such trading day; (3) if we call such Notes for redemption, at any time prior to the close of business on the business day immediately preceding the redemption date; or (4) upon the occurrence of specified corporate events. On or after March 1, 2025 until the close of business on the second scheduled trading day immediately preceding the maturity date, a holder may convert all or any portion of its Notes at any time, regardless of the foregoing.

The conversion rate will initially be 26.7271 shares of our common stock per $1,000 principal amount of Notes (equivalent to an initial conversion price of approximately $37.42 per share of our common stock). The conversion rate is subject to adjustment in some events but will not be adjusted for any accrued and unpaid interest. In addition, following certain corporate events that occur prior to the maturity date or if we deliver a notice of redemption, we will, in certain circumstances, increase the conversion rate for a holder who elects to convert its Notes in connection with such a corporate event or convert its Notes called for redemption in connection with such notice of redemption, as the case may be.

We may not redeem the Notes prior to June 5, 2023. We may redeem for cash all or any portion of the Notes, at our option, on a redemption date occurring on or after June 5, 2023 and on or before the 31st scheduled trading day immediately before the maturity date, if the last reported sale price of our common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive), including the trading day immediately preceding the date on which we provide notice of redemption, during any 30 consecutive trading day period ending on, and including, the trading day immediately preceding the date on which we provide notice of redemption at a redemption price equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. No sinking fund is provided for the Notes.

On October 1, 2022, we adopted ASU 2020-06 based on a modified retrospective transition method. No prior-period information has been retrospectively adjusted. After the adoption of ASU 2020-06, the Notes are no longer bifurcated into a separate liability and equity component. The Notes are accounted for as a single liability. As of December 31, 2022, the carrying amount of the Notes was $172.2 million, net of unamortized issuance costs of $2.8 million. The issuance costs related to the Notes are being amortized to interest expense over the contractual term. Refer to Note 2 - Significant Accounting Policies for the impact of our adoption.

As of December 31, 2022 and September 30, 2022, the carrying amount of the equity component, net of taxes and transaction costs, was $0 and $14.4 million, respectively.

The conditional conversion feature of the Notes was not triggered during the three months ended December 31, 2022. As of December 31, 2022, the Notes were not convertible. As of this Quarterly Report, no Notes have been converted by the holders. Whether any of the Notes will be convertible in future quarters will depend on the satisfaction of one or more of the conversion conditions in the future. If one or more holders elect to convert their Notes at a time when any such Notes are convertible, unless we elect to satisfy our conversion obligation by delivering solely shares of our common stock (other than paying cash in lieu of delivering any fractional share), we would be required to settle a portion or all of our conversion obligation through the payment of cash, which could adversely affect our liquidity.

Senior Credit Facilities

On June 12, 2020 (the “Financing Closing Date”), we entered into a Credit Agreement, by and among the Borrower, the lenders and issuing banks party thereto and Wells Fargo Bank, N.A., as administrative agent (the “Credit Agreement”), consisting of a four-year senior secured term loan facility in the aggregate principal amount of $125.0 million (the “Term Loan Facility”). The net proceeds from the issuance of the Term Loan Facility were $123.0 million. We also entered into a senior secured first-lien revolving credit facility in an aggregate principal amount of $50.0 million (the “Revolving Facility” and, together with the Term Loan Facility, the “Senior Credit Facilities”), which may be drawn on in the event that our working capital and other cash needs are not supported by our operating cash flow. As of December 31, 2022, there were no amounts outstanding under the Revolving Facility.

On December 17, 2020 (the “Amendment No. 1 Effective Date”), we entered into Amendment No. 1 to the Credit Agreement (“Amendment No. 1"). Amendment No. 1 extended the scheduled maturity date of the revolving credit and term facilities from June 12, 2024 to April 1, 2025.

Amendment No. 1 revised certain interest rates in the Credit Agreement. Following delivery of a compliance certificate for the first full fiscal quarter after the Amendment No. 1 Effective Date, the applicable margins for the revolving credit and term facilities is subject to a pricing grid based upon the net total leverage ratio as follows (i) if the net total leverage ratio is greater than 3.00 to 1.00, the applicable margin is LIBOR plus 3.00% or ABR plus 2.00%; (ii) if the net total leverage ratio is less than or equal to 3.00 to 1.00 but greater than 2.50 to 1.00, the applicable margin is LIBOR plus 2.75% or ABR plus 1.75%; (iii) if the net total leverage ratio is less than or equal to 2.50 to 1.00 but greater than 2.00 to 1.00, the applicable margin is LIBOR plus 2.50% or ABR plus 1.50%; (iv) if the net total leverage ratio is less than or equal to 2.00 to 1.00 but greater than 1.50 to 1.00, the applicable margin is LIBOR plus 2.25% or ABR plus 1.25%; and (v) if the net total leverage ratio is less than or equal to 1.50 to 1.00, the applicable margin is LIBOR plus 2.20% or ABR plus 1.00%. As a result of Amendment No. 1, the applicable LIBOR floor was reduced from 0.50% to 0.00%.

In addition, the quarterly commitment fee required to be paid based on the unused portion of the revolving facility is subject to a pricing grid based upon the net total leverage ratio as follows (i) if the net total leverage ratio is greater than 3.00 to 1.00, the unused line fee is 0.500%; (ii) if the net total leverage ratio is less than or equal to 3.00 to 1.00 but greater than 2.50 to 1.00, the unused line fee is 0.450%; (iii) if the net total leverage ratio is less than or equal to 2.50 to 1.00 but greater than 2.00 to 1.00, the unused line fee is 0.400%; (iv) if the net total leverage ratio is less than or equal to 2.00 to 1.00 but greater than 1.50 to 1.00, the unused line fee is 0.350%; and (v) if the net total leverage ratio is less than or equal to 1.50 to 1.00, the unused line fee is 0.300%.

Through the fiscal quarter ending December 31, 2022, we are obligated to make quarterly principal payments in an aggregate amount equal to 1.25% of the original principal amount of the Term Loan Facility. From the fiscal quarter ending March 31, 2023 and for each fiscal quarter thereafter, we are obligated to make quarterly principal payments in an aggregate amount equal to 2.50% of the original principal amount of the Term Loan Facility, with the balance payable at the maturity date thereof.

The Credit Agreement contains certain affirmative and negative covenants customary for financings of this type that, among other things, limit our and our subsidiaries’ ability to incur additional indebtedness or liens, to dispose of assets, to make certain fundamental changes, to designate subsidiaries as unrestricted, to make certain investments, to prepay certain indebtedness and to pay dividends, or to make other distributions or redemptions/repurchases, in respect of our and our subsidiaries’ equity interests. In addition, the Credit Agreement contains financial covenants, each tested quarterly, (1) a net secured leverage ratio of not greater than 3.25 to 1.00; (2) a net total leverage ratio of not greater than 4.25 to 1.00; and (3) minimum liquidity of at least $75 million. The Credit Agreement also contains events of default customary for financings of this type, including certain customary change of control events. As of December 31, 2022, we were in compliance with all Credit Agreement covenants.

On November 22, 2022 (the "Amendment No. 2 Effective Date"), we entered into Amendment No. 2 to the Credit Agreement ("Amendment No. 2"). Amendment No. 2 modified certain financial covenants between the fiscal quarter ended March 31, 2023 to the fiscal quarter ended December 31, 2023 (the "covenant adjustment period"). During the covenant adjustment period, each tested quarterly, we are required to maintain (1) a net secured leveraged ratio of not greater than 4.25 to 1.00; (2) minimum liquidity of at least $125 million; and (3) aggregate capital expenditures less than $7.5 million. The net total leverage ratio will be waived during the covenant adjustment period. At the conclusion of the covenant adjustment period, the original financial covenants will resume.

Amendment No. 2 was accounted for a debt modification, and therefore, $0.4 million of the refinancing fees paid directly to the lender were recorded as deferred debt issuance costs, and $0.1 million of the refinance fees paid to third parties were expensed in the period.

Amendment No. 2 revised certain interest rates in the Credit Agreement. The applicable margins for the revolving credit and term facilities is subject to a pricing grid based upon the net total leverage ratio as follows (i) if the net total leverage ratio is greater than 3.00 to 1.00, the applicable margin is SOFR plus 10 basis point credit spread adjustment plus 3.00% or ABR plus 2.00%; (ii) if the net total leverage ratio is less than or equal to 3.00 to 1.00 but greater than 2.50 to 1.00, the applicable margin is SOFR plus 10 basis point credit spread adjustment plus 2.75% or ABR plus 1.75%; (iii) if the net total leverage ratio is less than or equal to 2.50 to 1.00 but greater than 2.00 to 1.00, the applicable margin is SOFR plus 10 basis point credit spread adjustment plus 2.50% or ABR plus 1.50%; (iv) if the net total leverage ratio is less than or equal to 2.00 to 1.00 but greater than 1.50 to 1.00, the applicable margin is SOFR plus 10 basis point credit spread adjustment plus 2.25% or ABR plus 1.25%; and (v) if the net total leverage ratio is less than or equal to 1.50 to 1.00, the applicable margin is SOFR plus 10 basis point credit spread adjustment plus 2.20% or ABR plus 1.00%. During the covenant adjustment period, and until the delivery of a compliance certificate for the first full fiscal quarter after the covenant adjustment period, the applicable margin will be SOFR plus 10 basis point credit spread adjustment plus 3.00% or ABR plus 2.00%.

For the three months ended December 31, 2021, the interest rate was LIBOR plus 2.25%. Prior to the Amendment No. 2 Effective Date, the interest rate was LIBOR plus 2.25%. From the Amendment No. 2 Effective Date until the quarter ended December 31, 2022, the interest rate was SOFR plus a credit spread adjustment of 10 basis points plus 2.25%. Total interest expense relating to the Senior Credit Facilities for the three months ended December 31, 2022 and 2021 was $1.9 million and $0.9 million, respectively. Amounts reflect the coupon and accretion of the discount.
