CREDIT FACILITY AND LONG-TERM DEBT

CONVERTIBLE NOTES

Convertible Notes

On September 17, 2019, the Company issued $86.25 million aggregate principal amount of 3.750% Convertible Senior Notes due 2026 (the "Notes"), which included the exercise in full of an $11.25 million purchase option, to certain financial institutions as the initial purchasers of the Notes (the "Initial Purchasers"). The Notes are senior unsecured obligations of the Company. The Notes were issued pursuant to an Indenture, dated September 17, 2019 (the “Indenture”), between the Company and U.S. Bank National Association, as trustee.

The net proceeds from the sale of the Notes were approximately $83.7 million after deducting the initial purchasers’ discounts and the offering expenses payable by the Company. The Company used approximately $12.8 million of the net proceeds from the Notes to repay all outstanding indebtedness on its existing Credit Facility with JPMorgan Chase Bank, N.A., and an additional $2.0 million to fully fund a cash collateralized, letter of credit facility under a new Credit Facility. The Company subsequently terminated the Credit Facility with JPMorgan Chase Bank, N.A. on December 31, 2019. The Company expects to use the remainder of the net proceeds from the sale of the Notes to fund our intended expansion efforts, including through acquisitions of complementary businesses or technologies or other strategic transactions, and for working capital and other general corporate purposes.

The Notes are senior unsecured obligations of the Company and will rank senior in right of payment to any of our indebtedness that is expressly subordinated in right of payment to the Notes; equal in right of payment to any of our unsecured indebtedness that is not so subordinated; effectively junior in right of payment to any of our secured indebtedness to the extent of the value of assets securing such indebtedness; and structurally junior to all indebtedness and other liabilities (including trade payables) of our subsidiaries.

The Company pays interest on the Notes semiannually in arrears at a rate of 3.750% per annum on March 15 and September 15 of each year. The Notes are convertible based upon an initial conversion rate of 11.5434 shares of the Company’s common stock per $1,000 principal amount of Notes (equivalent to a conversion price of approximately $86.63 per share of common stock). The Notes would convert in full into 995,618 shares of common stock based on the initial conversion rate. The conversion rate will be subject to standard anti-dilution adjustments upon the occurrence of certain events but will not be adjusted for accrued and unpaid interest. The interest rate on the Notes may be increased by up to 0.50% upon the occurrence of certain events of default or non-timely filings until such matter has been cured.

The Indenture includes customary covenants, but no financial or operating covenants or restrictions on the payments of dividends, the incurrence of indebtedness or the issuance or repurchase of securities, and sets forth certain events of default and certain types of bankruptcy or insolvency events of default involving the Company after which the Notes become automatically due and payable. The Company can settle any conversions of the Notes in cash, shares of the Company’s common stock or a combination thereof, with the form of consideration determined at the Company’s election. The Company intends to settle the principal value of the Notes in cash and issue shares of the Company’s common stock to settle the intrinsic value of the conversion feature. There can be no guarantee, however, that any settlement will be affected by the Company as currently intended, and the timing and other factors of any settlement, many of which may be outside the Company's control, could impact the actual amounts to be settled in either cash or common stock.

The Notes will mature on September 15, 2026, unless earlier repurchased, redeemed or converted. Prior to March 15, 2026, holders may convert all or a portion of their Notes only under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on December 31, 2019 (and only during such calendar quarter), if the last reported sale price of the Company’s 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 on each applicable trading day; (2) during the 5 business day period after any 5 consecutive trading day period (the "Notes measurement period") in which the trading price per $1,000 principal amount of Notes for each trading day of the Notes 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 on each such trading day; (3) with respect to any Notes called for redemption by the Company, at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date; or (4) upon the occurrence of specified corporate events. On and after March 15, 2026 until the close of business on the scheduled trading day immediately preceding the maturity date, holders may convert their

Notes at any time, regardless of the foregoing circumstances. Holders of Notes who convert their Notes in connection with a notice of a redemption or a make-whole fundamental change (each as defined in the Indenture) may be entitled to a premium in the form of an increase in the conversion rate of the Notes.

The Company may not redeem the Notes prior to September 20, 2023. On or after September 20, 2023, the Company may redeem for cash all or part of the Notes if the last reported sale price of the Company’s common stock equals or exceeds 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 the redemption. The redemption price will be 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest, if any. No sinking fund is provided for the Notes.

Upon the occurrence of a fundamental change (as defined in the Indenture), holders may require the Company to repurchase all or a portion of their Notes for cash at a price equal to 100% of the principal amount of the Notes to be repurchased plus any accrued but unpaid interest to, but excluding, the fundamental change repurchase date.

In accounting for the issuance of the Notes prior to the adoption of ASU 2020-06, the Company initially separated the Notes into liability and equity components. The carrying amount of the liability component was calculated by measuring the fair value of a similar liability that does not have an associated convertible feature. The carrying amount of the equity component, representing the conversion option, which does not meet the criteria for separate accounting as a derivative as it is indexed to the Company's own stock, was determined by deducting the fair value of the liability component from the par value of the Notes. The difference between the principal amount of the Notes and the liability component represented the debt discount, which was recorded as a direct deduction from the related debt liability in the Consolidated Balance Sheet and amortized to interest expense using the effective interest method over the term of the Notes. The effective interest rate of the Notes was 15.3% per annum prior to adopting ASU 2020-06. The equity component of the Notes was approximately $39.5 million, net of allocated issuance costs of $1.5 million. The Company allocated transaction costs related to the Notes using the same proportions as the proceeds from the Notes. Transaction costs attributable to the liability component were recorded as a direct deduction from the related debt liability in the Consolidated Balance Sheet and amortized to interest expense over the term of the Notes, and transaction costs attributable to the equity component were netted with the equity component in shareholders’ equity.

In addition, the Company determined that the additional interest that could be due to the holders of the Notes upon an event of default or non-timely filing represented an embedded derivative feature that should be bifurcated from the Notes. The Company concluded that the fair value of this embedded derivative feature was de minimis upon the issuance of the Notes and at December 31, 2022.

The Company early adopted ASU 2020-06, effective January 1, 2021, which simplifies the accounting for certain convertible instruments. Under the new standard, qualifying convertible debt is accounted for as a single liability measured at its amortized cost, as long as no other features require bifurcation and recognition as derivatives. As a result of ASU 2020-06, the Company's cash interest expense is not impacted, however, the Company's non-cash interest accretion is limited to the amortization of debt issuance costs under ASC 835-30. The new effective interest rate of the Notes post-adoption is 4.35%. The Company also reversed the conversion feature amount recorded in APIC and reversed the difference in non-cash interest expense via retained earnings.

During the years ended December 31, 2022 and 2021, no portion of the Notes was converted and the liability was classified as long-term debt on the Company's Consolidated Balance Sheet as of December 31, 2022.

The following table summarizes the net carrying amount of the Notes as of December 31, 2022 (in thousands):

	December 31, 2022		December 31, 2021
Principal amount of the Notes	$	86,250	$	86,250
Unamortized debt discount	(1,783)		(2,216)
Net carrying amount	$	84,467	$	84,034

Interest expense related to the Notes is comprised of the amortization of debt discount and debt issuance costs and the contractual coupon interest as follows (in thousands):

	Year Ended December 31,
	2022		2021		2020
Interest expense related to contractual coupon interest2	$	3,234	$	3,755	$	3,234
Interest expense related to amortization of debt discount1	434		415		3,111
Total interest expense	$	3,668	$	4,170	$	6,345

1 Immaterial out of period error correction of non-cash interest identified and recorded during the fourth fiscal quarter of 2020.

2The year ended December 31, 2021 includes $0.5 million of additional interest expense related to the restrictive legend on the Notes. The legend was removed as of December 31, 2021 and the Notes will not accrue additional interest in future periods.

As of December 31, 2022, the remaining period over which the unamortized discount will be amortized is 3.8 years.

The estimated fair value of the Notes was $89.1 million and $194.3 million as of December 31, 2022 and 2021, respectively, determined through consideration of quoted market prices in less active markets. The fair value measurement is classified as Level 2 in the fair value hierarchy, which is defined in ASC 820 as inputs other than quoted prices in active markets that are either directly or indirectly observable. Based on our closing stock price of $62.16 on December 31, 2022, the if-converted value did not exceed the aggregate principal amount of the Notes.
