On October 14, 2020, the Company entered into a senior secured credit facility which was amended on February 23, 2021 (the “First Amendment”) and again on February 26, 2021 (the “Second Amendment”). The senior secured facility consisted originally of (i) a $575 million senior secured 7-year term loan facility (the “Term Loan Facility”) and (ii) a $150 million senior secured 5-year revolving credit facility (the “Revolving Credit Facility” and, together with the Term Loan Facility, the “Senior Secured Credit Facility”). The First Amendment, in the case of Eurocurrency borrowings, lowered the London interbank offered rate floor to 50 basis points from 100 basis points and lowered the applicable margin to 325 basis points from 400 basis points per annum. The Second Amendment increased the borrowing capacity of the Revolving Credit Facility from $150 million to $200 million.

The outstanding balance on the Term Loan Facility was $312.5 million and $326.8 million as of December 31, 2022 and 2021, respectively. The balance of the Term Loan Facility is presented in the accompanying consolidated balance sheets, net of debt discount and issuance costs of $19.1 million and $23.3 million at December 31, 2022 and 2021, respectively.

Under the Revolving Credit Facility, the Company had no outstanding balance as of both December 31, 2022 and 2021, $38.8 million and $13.6 million in standby letters of credit as of December 31, 2022 and 2021, respectively, and availability of $161.2 million and $186.4 million as of December 31, 2022 and 2021, respectively.

Terms and Conditions of the Senior Secured Credit Facility

Interest Rates

The interest rates applicable to the loans under the Term Loan Facility equal, at our option, either, (i) in the case of ABR borrowings, the highest of (a) the Federal Funds Rate as of such day plus 50 basis points, (b) the prime rate and (c) the adjusted LIBOR rate as of such day for a deposit in U.S. dollars with a maturity of one month plus 100 basis points, provided that in no event shall the ABR be less than 150 basis points, plus, in each case, the applicable margin of 300 basis points per annum; or (ii) in the case of Eurocurrency borrowings, the greater of (a) the LIBOR for the relevant currency, adjusted for statutory reserve requirements, and (b) 100 basis points, plus, in each case, the applicable margin of 400 basis points per annum. Pursuant to the First

Amendment, (i) the applicable margin (a) with respect to ABR borrowings was reduced to 225 basis points and (b) with respect to Eurocurrency borrowings was reduced to 325 basis points and (ii) the LIBOR floor referred to in clause (ii)(b) above was reduced from 100 to 50 basis points. Applicable interest rate at December 31, 2022 was 7.94%

The interest rates applicable to the loans under the Revolving Facility equal, at our option, either, (i) in the case of ABR borrowings, the highest of (a) the Federal Funds Rate as of such day plus 50 basis points, (b) the prime rate and (c) the adjusted LIBOR rate as of such day for a deposit in U.S. dollars with a maturity of one month plus 100 basis points, provided that in no event shall the ABR be less than 150 basis points, plus, in each case, the applicable margin of 225 basis points per annum; or (ii) in the case of Eurocurrency borrowings, the greater of (a) the London interbank offered rate for the relevant currency, adjusted for statutory reserve requirements, and (b) 50 basis points, plus, in each case, the applicable margin of 325 basis points per annum.

Prepayments and Amortization

The Term Loan Facility amortizes in equal quarterly installments in aggregate annual amounts equal to 1.00% per annum of the original principal amount of the loans funded thereunder. There is no scheduled amortization under the Revolving Credit Facility.

Loans under the Revolving Credit Facility may be voluntarily prepaid in whole, or in part, in each case without premium or penalty. Loans under the Term Loan Facility may be voluntarily prepaid in whole, or in part, in each case without premium or penalty (other than a 1% premium with respect to prepayments on account of certain “repricing events,” subject to exceptions, occurring within 12 months of the closing date of the Senior Secured Credit Facility).

Additionally, the Term Loan Facility requires an annual excess cash flow calculation, for which the prescribed formula did not result in requiring the Company to make an advance principal payment for the year ended December 31, 2022.

Restrictive Covenants and Other Matters

The Revolving Credit Facility includes a springing financial maintenance covenant that is tested on the last day of each fiscal quarter if the outstanding loans and certain other credit extensions under the Revolving Credit Facility exceed 35% of the aggregate amount of commitments thereunder, subject to customary exclusions and conditions. If the financial maintenance covenant is triggered, the first lien net leverage ratio will be tested for compliance not to exceed 7.10 to 1.00. As of December 31, 2022, the Company was in compliance with all the required covenants.

The Senior Secured Credit Facility also contains affirmative and negative covenants customary for financings of this type, including covenants that restrict our incurrence of indebtedness and liens, dispositions, investments, acquisitions, restricted payments, and transactions with affiliates. The Senior Secured Credit Facility also includes customary events of default, including the occurrence of a change of control.

Guarantees and Security

The obligations under the Senior Secured Credit Facility are guaranteed by ATI Investment Sub, Inc. and its wholly owned domestic subsidiaries other than certain immaterial subsidiaries and other excluded subsidiaries. The obligations under the Senior Secured Credit Facility are secured by a first priority security interest in substantially all of the future property and assets of the guarantor and the borrower, Array Tech, Inc. (f/k/a Array

Technologies, Inc.), including accounts receivable, inventory, equipment, general intangibles, intellectual property, investment property, other personal property, material owned real property, cash and proceeds of the foregoing.

Convertible Debt

Convertible debt consisted of the following (in thousands):

	December 31,
	2022		2021
1.00% Convertible Senior Notes	$	425,000	$	425,000
Unamortized discount and issuance costs	(11,248)		(13,137)
1.00% Convertible Senior Notes, net	$	413,752	$	411,863

On December 3, 2021 and December 9, 2021, the Company completed a $425.0 million private offering ($375 million and $50 million, respectively), of its 1.00% Convertible Senior Notes due 2028, resulting in proceeds of $413.3 million ($364.7 million and $48.6 million, respectively) after deducting the original issue discount of 2.75%. The Convertible Notes were issued pursuant to an indenture, dated December 3, 2021, between the Company and U.S. Bank National Association, as trustee (the “Indenture”).

For the year ended December 31, 2022, interest expense related to the Convertible Notes was $6.1 million, of which, $4.2 million was contractual interest and of $1.9 million was amortization of debt discount and issuance costs. Interest expense for the year ended December 31, 2021 was $0.4 million, of which, $0.3 million was contractual interest and $0.1 million amortization of debt discount and issuance costs. The discount and issuance costs will be amortized over the life of the debt using the effective interest rate of 1.5%.

The Convertible Notes are senior unsecured obligations of the Company that mature on December 1, 2028, unless earlier converted, redeemed, or repurchased. The Convertible Notes bear interest at a rate of 1.00% per year, payable semiannually in arrears on June 1 and December 1 of each year, beginning on June 1, 2022.

The Convertible Notes were not convertible during the year ended December 31, 2022 and none have been converted to date. As the average market price of the Company’s common stock has not exceeded the exercise price since inception, there was no dilutive impact to earnings per share for the year ended December 31, 2022.

Redemption

At any time prior to the close of business on the business day immediately preceding June 1, 2028, the Convertible Notes are convertible at the option of the holders only under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on March 31, 2022 (and only during such calendar 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 calendar quarter is greater than or equal to 130% of the conversion price then in effect 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 the Company’s common stock and the conversion rate for the Convertible Notes on each such trading

day; (3) if the Company calls such Convertible Notes for redemption, at any time prior to the close of business on the second scheduled trading day immediately preceding the redemption date, but only with respect to the Convertible Notes called (or deemed called) for redemption; or (4) upon the occurrence of specified corporate events as described in the Indenture. On or after June 1, 2028 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders of the Convertible Notes may convert all or any portion of their Convertible Notes at any time regardless of the foregoing circumstances. Upon conversion of the Convertible Notes, the Company will pay cash up to the aggregate principal amount of the Convertible Notes to be converted and pay or deliver, as the case may be, cash, shares of the Company’s common stock or a combination of cash and shares of the Company’s common stock, at the Company’s election, in respect of the remainder, if any, of the Company’s conversion obligation in excess of the aggregate principal amount of the Convertible Notes being converted.

The Company may redeem (an “Optional Redemption”) for cash all or any portion of the Convertible Notes, at its option, on or after December 6, 2025, if the last reported sale price of the Company’s common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which the Company provides notice of redemption at a redemption price equal to 100% of the principal amount of the Convertible Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. If the Company redeems less than all the outstanding Convertible Notes, at least $100 million aggregate principal amount of Convertible Notes must be outstanding and not subject to redemption as of the date of the relevant notice of redemption. No sinking fund is provided for the Convertible Notes.

The conversion rate for the Convertible Notes was initially 41.9054 shares of the Company’s common stock per $1,000 principal amount of the Convertible Notes, which was equivalent to an initial conversion price of approximately $23.86 per share of common stock or 10.1 million shares of common stock. The initial conversion price of the Convertible Notes represented a premium of approximately 32.5% to the last reported sale price of the Company’s common stock on the Nasdaq Global Market on November 30, 2021. The conversion rate for the Convertible Notes is subject to adjustment under certain circumstances in accordance with the terms of the Indenture. In addition, following certain corporate events that occur prior to the maturity date of the Convertible Notes or if the Company delivers a notice of redemption in respect of the Convertible Notes, the Company will, under certain circumstances, increase the conversion rate of the Convertible Notes for a holder who elects to convert its Convertible Notes (or any portion thereof) in connection with such a corporate event or convert its Convertible Notes called (or deemed called) for redemption during the related Redemption Period (as defined in the Indenture), as the case may be.

If the Company undergoes a Fundamental Change (as defined in the Indenture), holders may require, subject to certain conditions and exceptions, the Company to repurchase for cash all or any portion of their Convertible Notes at a Fundamental Change Repurchase Price (as defined in the Indenture) equal to 100% of the principal amount of the Convertible Notes to be repurchased, plus accrued and unpaid interest, to, but excluding, the Fundamental Change Repurchase Date (as defined in the Indenture).

The Indenture includes customary covenants and sets forth certain events of default after which the Convertible Notes may be declared immediately due and payable and sets forth certain types of bankruptcy or insolvency events of default involving the Company or certain of its subsidiaries after which the Convertible Notes become automatically due and payable.

Capped Calls

In connection with the issuances of the Convertible Notes, the Company paid $52.9 million, in aggregate, to enter into Capped Call Option Agreements to reduce the potential dilution to holders of the Company’s common stock after a conversion of the Convertible Notes. Specifically, upon the exercise of the capped call instruments issued pursuant to the agreements (the “Capped Calls”), the Company would receive shares of its common stock equal to approximately 17.8 million shares (a) multiplied by (i) the lower of $36.0200 or the then-current market price of its common stock, less (ii) the applicable exercise price, and (b) divided by the then-current market price of its common stock. The results of this formula are that the Company would receive more shares as the market price of its common stock exceeds the exercise price and approaches the cap, which was initially $36.0200 per share.

Consequently, if the Convertible Notes are converted, then the number of shares to be issued by the Company would be effectively partially offset by the shares of common stock received by the Company under the Capped Calls as they are exercised. The formula above would be adjusted in the event of certain specified extraordinary events affecting the Company, including a merger; a tender offer; nationalization, insolvency or delisting of the Company’s common stock; changes in law; failure to deliver; insolvency filing; stock splits, combinations, dividends, repurchases or similar events; or an announcement of certain of the preceding actions.

The Company can also elect to receive the equivalent value of cash in lieu of shares of common stock upon settlement, except in certain circumstances. The Capped Calls expire on December 1, 2028 and terminate upon the occurrence of certain extraordinary events such as a merger, tender offer, nationalization, insolvency, delisting, event of default, a change in law, failure to deliver, an announcement of certain of these events, or an early conversion of the Convertible Notes. Although intended to reduce the net number of shares of common stock issued after a conversion of the Convertible Notes, the Capped Calls were separately negotiated transactions, are not a part of the terms of the Convertible Notes, and do not affect the rights of the holders of the Convertible Notes. The Capped Calls meet the criteria for equity classification because they are indexed to the Company’s common stock and the Company has discretion to settle the Capped Calls in shares or cash. As a result, the amount paid for the Capped Calls was recorded as a reduction to additional paid-in capital. The Capped Calls are excluded from the calculation of diluted net income (loss) per share attributable to common stockholders as their effect is antidilutive.

The Company made a tax election to integrate the Convertible Notes and the Capped Calls. The accounting impact of this tax election makes the Capped Calls deductible as original issue discount interest for tax purposes over the term of the note, and results in a $10.8 million deferred tax asset recorded as an adjustment to additional paid-in capital on the consolidated balance sheets as of December 31, 2022.

Other Debt

In connection with the STI Acquisition, the Company assumed the debt obligations of STI outstanding with various local banking and credit institutions (“Other Debt”). As of December 31, 2022, the total outstanding balance on these debt obligations was $52.0 million, of which, approximately $20.3 million is subject to fixed interest rates ranging from 0.55% to 4.52%. The remaining $31.7 million is subject to variable interest rates ranging from 1.99% to 3.96%. Total interest expense for Other Debt in 2022 was $2.4 million.
