On January 25, 2021, the Company entered into the Second Amendment to the Amended and Restated Credit Agreement dated December 19, 2017, which increased the senior secured revolving loan facility from $500,000 to $850,000 and extended the maturity date from December 18, 2022 to November 15, 2025 (the “Credit Facility”). In connection with the Second Amendment, certain lenders exited the Credit Facility. The Company performed an extinguishment versus modification assessment on a lender‑by‑lender basis resulting in the write‑off of unamortized debt issuance costs of $353 and the capitalization of fees paid to lenders and third parties of $3,577. Debt issuance costs are amortized to interest expense through the maturity date of November 15, 2025.

On June 22, 2021, the Company entered into the Third Amendment to the Credit Facility, which increased the aggregate amount of approved convertible debt to permit the issuance and sale of additional convertible senior notes. See the section titled “—Convertible Senior Notes—2027 Notes” below.

In addition to the senior secured revolving loan facility, the Credit Facility also provides up to $50,000 of letters of credit and other incremental borrowings subject to availability, including a $85,000 multi‑currency swing‑line sub‑facility and a $200,000 incremental “accordion” sub‑facility. The Company had $150 of letters of credit and surety bonds outstanding as of September 30, 2021 and December 31, 2020. As of September 30, 2021 and December 31, 2020, the Company had $781,996 and $253,850 available under the Credit Facility.

Under the Credit Facility, the Company may make either Euro currency or non‑Euro currency interest rate elections. Interest on the Euro currency borrowings bear a base interest rate of LIBOR plus a spread ranging from 125 basis points (“bps”) to 225 bps as determined by the Company’s net leverage ratio. Under the non‑Euro currency elections, Credit Facility borrowings bear a base interest rate of the highest of (i) the prime rate, (ii) the overnight bank funding effective rate plus 50 bps, or (iii) LIBOR plus 100 bps, plus a spread ranging from 25 bps to 125 bps as determined by the Company’s leverage ratio. In addition, a commitment fee for the unused Credit Facility ranges from 20 bps to 30 bps as determined by the Company’s net leverage ratio.

Borrowings under the Credit Facility are guaranteed by all of the Company’s first tier domestic subsidiaries and are secured by a first priority security interest in substantially all of the Company’s and the guarantors’ U.S. assets and 65% of the stock of their directly owned foreign subsidiaries. The Credit Facility contains both affirmative and negative covenants, including maximum leverage ratios. As of September 30, 2021 and December 31, 2020, the Company was in compliance with all covenants in its Credit Facility debt agreements.

The agreement governing the Credit Facility contains customary events of default, including, without limitation, payment defaults, breaches of representations and warranties, covenants defaults, cross-defaults to certain other indebtedness in excess of $50,000, certain events of bankruptcy and insolvency, judgment defaults in excess of $10,000, failure of any security document supporting the Credit Facility to be in full force and effect, and a change of control.

Voluntary prepayments of amounts outstanding under the Credit Facility, in whole or in part, are permitted at any time, so long as the Company gives notice as required by the Credit Facility. However, if prepayment is made with respect to a LIBOR‑based loan and the prepayment is made on a date other than an interest payment date, the Company must pay customary breakage costs.

On January 26, 2021, the Company completed a private offering of $690,000 of 0.125% convertible senior notes due 2026. The 2026 Notes were issued pursuant to an indenture, dated as of January 26, 2021, between the Company and Wilmington Trust, National Association, as trustee (the “2026 Trustee”) (the “2026 Indenture”). Interest will accrue from January 26, 2021 and will be payable semi‑annually in arrears in cash on January 15 and July 15 of each year, with the first payment due on July 15, 2021. The 2026 Notes will mature on January 15, 2026, unless earlier converted, redeemed or repurchased. The Company incurred $18,055 of expenses in connection with the 2026 Notes offering consisting of transaction costs. The Company used $25,530 of the net proceeds from the sale of the 2026 Notes to pay the premiums of the capped call options described further below, and approximately $250,500 to repay outstanding indebtedness under the Credit Facility and to pay related fees and expenses. The Company used the remainder of the net proceeds from the sale of the 2026 Notes for general corporate purposes and towards funding certain acquisitions, including Seequent (see Note 4).

Prior to October 15, 2025, the 2026 Notes will be convertible at the option of the holder only under the following circumstances: (1) during any calendar quarter (and only during such quarter) commencing after the calendar quarter ending on June 30, 2021, if the last reported sale price per share of the Company’s Class B Common Stock exceeds 130% of the conversion price for each of at least 20 trading days, whether or not consecutive, during the 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter; (2) during the five consecutive business days immediately after any ten consecutive trading day period (such ten consecutive trading day period, the “measurement period”) in which the trading price per $1 principal amount of 2026 Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price per share of the Company’s Class B Common Stock on such trading day and the conversion rate on such trading day; (3) upon the occurrence of certain corporate events or distributions on the Company’s Class B Common Stock, as described in the 2026 Indenture; and (4) if the Company calls the 2026 Notes for redemption. On or after October 15, 2025 until 5:00 p.m., New York City time, on the second scheduled trading day immediately before the maturity date, the 2026 Notes will be convertible at the option of the holder at any time.

The Company will settle conversions by paying or delivering, as applicable, cash, shares of the Company’s Class B Common Stock or a combination of cash and shares of the Company’s Class B Common Stock, at the Company’s election, based on the applicable conversion rate. The initial conversion rate is 15.5925 shares of the Company’s Class B Common Stock per $1 principal amount of 2026 Notes, which represents an initial conversion price of approximately $64.13 per share, and is subject to adjustment as described in the 2026 Indenture. If a “make-whole fundamental change” (as defined in the 2026 Indenture) occurs, then the Company will, in certain circumstances, increase the conversion rate for a specified period of time.

The Company will have the option to redeem the 2026 Notes in whole or in part at any time on or after January 20, 2024 and on or before the 40th scheduled trading day immediately before the maturity date if the last reported sale price per share of the Company’s Class B common stock exceeds 130% of the conversion price on (1) each of at least 20 trading days, whether or not consecutive, during any 30 consecutive trading days ending on, and including, the trading day immediately before the date the Company sends the related redemption notice; and (2) the trading day immediately before the date the Company sends such notice. The redemption price will be equal to the principal amount of the 2026 Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date.

Upon a fundamental change (as defined in the 2026 Indenture), holders may, subject to certain exceptions, require the Company to purchase their 2026 Notes in whole or in part for cash at a price equal to the principal amount of the 2026 Notes to be purchased, plus accrued and unpaid interest, if any, to, but excluding, the fundamental change repurchase date (as defined in the 2026 Indenture). In addition, upon a Make‑Whole Fundamental Change (as defined in the 2026 Indenture), the Company will, under certain circumstances, increase the applicable conversion rate for a holder that elects to convert its 2026 Notes in connection with such Make‑Whole Fundamental Change. No adjustment to the conversion rate will be made if the stock price in such Make‑Whole Fundamental Change is either less than $44.23 per share or greater than $210.00 per share. The Company will not increase the conversion rate to an amount that exceeds 22.6090 shares per $1 principal amount of 2026 Notes, subject to adjustment. The 2026 Indenture also contains a customary merger covenant.

Under the 2026 Indenture, the 2026 Notes may be accelerated upon the occurrence of certain customary events of default. If certain bankruptcy and insolvency‑related events of default with respect to the Company occur, the principal of, and accrued and unpaid interest on, all of the then outstanding 2026 Notes shall automatically become due and payable. If any other event of default occurs and is continuing, the 2026 Trustee by notice to the Company, or the holders of the 2026 Notes of at least 25% in principal amount of the outstanding 2026 Notes by notice to the Company and the 2026 Trustee, may declare the principal of, and accrued and unpaid interest on, all of the then outstanding 2026 Notes to be due and payable. Notwithstanding the foregoing, the 2026 Indenture provides that, to the extent the Company elects, the sole remedy for an event of default relating to certain failures by the Company to comply with reporting covenant in the 2026 Indenture consists exclusively of the right to receive additional interest on the 2026 Notes.

As discussed in Note 2, the Company early adopted ASU 2020‑06 as of January 1, 2021 and concluded the 2026 Notes will be accounted for as debt, with no bifurcation of the embedded conversion feature. Transaction costs were recorded as a direct deduction from the related debt liability in the consolidated balance sheet and are amortized to interest expense using the effective interest method over the term of the 2026 Notes. The effective interest rate for the 2026 Notes is 0.658%.

The 2026 Notes are the Company’s senior, unsecured obligations that rank senior in right of payment to the Company’s future indebtedness that is expressly subordinated to the 2026 Notes, rank equally in right of payment with the Company’s existing and future senior unsecured indebtedness that is not so subordinated (including the Company’s 2027 Notes, see the section titled “—2027 Notes” below), effectively subordinated to the Company’s existing and future secured indebtedness (including obligations under the Company’s senior secured credit facilities), to the extent of the value of the collateral securing such indebtedness, and structurally subordinated to all existing and future indebtedness and other liabilities (including trade payables and preferred equity (to the extent the Company is not a holder thereof)) of the Company’s subsidiaries. The 2026 Notes contain both affirmative and negative covenants. As of September 30, 2021, the Company was in compliance with all covenants in the 2026 Notes.

In connection with the pricing of the 2026 Notes, the Company entered into capped call options with certain of the initial purchasers or their respective affiliates and certain other financial institutions. The Company incurred $150 of expenses in connection with the capped call options. The capped call options are expected to reduce potential dilution to the Company’s Class B Common Stock upon any conversion of 2026 Notes and/or offset any cash payments the Company is required to make in excess of the principal amount of converted notes, as the case may be, with such reduction and/or offset subject to a cap. The cap price of the capped call options is initially $72.9795 per share, which represents a premium of 65% above the last reported sale price per share of the Company’s Class B Common Stock on the Nasdaq Global Select Market on January 21, 2021 and is subject to customary adjustments under the terms of the capped call options.

The capped call options were entered into in conjunction with the issuance of the 2026 Notes, however, they are legally separate agreements that can be separately exercised, with the receipt of shares under the capped call options having no effect on the 2026 Notes, and are legally detachable. As the capped call options are both legally detachable and separately exercisable from the 2026 Notes, the Company accounts for the capped call options separately from the 2026 Notes. The capped call options are indexed to the Company’s own common stock and classified in stockholders’ equity. As such, the premiums paid for the capped call options have been included as a net reduction to Additional paid-in capital in the consolidated balance sheet.

On June 28, 2021, the Company completed a private offering of $575,000 of 0.375% convertible senior notes due 2027. The 2027 Notes were issued pursuant to an indenture, dated as of June 28, 2021, between the Company and Wilmington Trust, National Association, as trustee (the “2027 Trustee”) (the “2027 Indenture”). Interest will accrue from June 28, 2021 and will be payable semi‑annually in arrears in cash on January 1 and July 1 of each year, with the first payment due on January 1, 2022. The 2027 Notes will mature on July 1, 2027, unless earlier converted, redeemed or repurchased. The Company incurred $15,065 of expenses in connection with the 2027 Notes offering consisting of transaction costs. As of September 30, 2021, $375 of the transaction costs were recorded in Accounts payable in the consolidated balance sheet. The Company used $25,875 of the net proceeds from the sale of the 2027 Notes to pay the premiums of the capped call options described further below, and $536,062 to repay outstanding indebtedness under the Credit Facility and to pay related fees and expenses.

Prior to April 1, 2027, the 2027 Notes will be convertible at the option of the holder only under the following circumstances: (1) during any calendar quarter (and only during such quarter) commencing after the calendar quarter ending on September 30, 2021, if the last reported sale price per share of the Company’s Class B Common Stock exceeds 130% of the conversion price for each of at least 20 trading days, whether or not consecutive, during the 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter; (2) during the five consecutive business days immediately after any ten consecutive trading day period (such ten consecutive trading day period, the “measurement period”) in which the trading price per $1 principal amount of 2027 Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price per share of the Company’s Class B Common Stock on such trading day and the conversion rate on such trading day; (3) upon the occurrence of certain corporate events or distributions on the Company’s Class B Common Stock, as described in the 2027 Indenture; and (4) if the Company calls the 2027 Notes for redemption. On or after April 1, 2027 until 5:00 p.m., New York City time, on the second scheduled trading day immediately before the maturity date, the 2027 Notes will be convertible at the option of the holder at any time.

The Company will settle conversions by paying or delivering, as applicable, cash, shares of the Company’s Class B Common Stock or a combination of cash and shares of the Company’s Class B Common Stock, at the Company’s election, based on the applicable conversion rate. The initial conversion rate is 12.0153 shares of the Company’s Class B Common Stock per $1 principal amount of 2027 Notes, which represents an initial conversion price of approximately $83.23 per share, and is subject to adjustment as described in the 2027 Indenture. If a “make-whole fundamental change” (as defined in the 2027 Indenture) occurs, then the Company will, in certain circumstances, increase the conversion rate for a specified period of time.

The Company will have the option to redeem the 2027 Notes in whole or in part at any time on or after July 5, 2024 and on or before the 40th scheduled trading day immediately before the maturity date if the last reported sale price per share of the Company’s Class B common stock exceeds 130% of the conversion price on (1) each of at least 20 trading days, whether or not consecutive, during any 30 consecutive trading days ending on, and including, the trading day immediately before the date the Company sends the related redemption notice; and (2) the trading day immediately before the date the Company sends such notice. The redemption price will be equal to the principal amount of the 2027 Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date.

Upon a fundamental change (as defined in the 2027 Indenture), holders may, subject to certain exceptions, require the Company to purchase their 2027 Notes in whole or in part for cash at a price equal to the principal amount of the 2027 Notes to be purchased, plus accrued and unpaid interest, if any, to, but excluding, the fundamental change repurchase date (as defined in the 2027 Indenture). In addition, upon a Make‑Whole Fundamental Change (as defined in the 2027 Indenture), the Company will, under certain circumstances, increase the applicable conversion rate for a holder that elects to convert its 2027 Notes in connection with such Make‑Whole Fundamental Change. No adjustment to the conversion rate will be made if the stock price in such Make‑Whole Fundamental Change is either less than $61.65 per share or greater than $325.00 per share. The Company will not increase the conversion rate to an amount that exceeds 16.2206 shares per $1 principal amount of 2027 Notes, subject to adjustment. The 2027 Indenture also contains a customary merger covenant.

Under the 2027 Indenture, the 2027 Notes may be accelerated upon the occurrence of certain customary events of default. If certain bankruptcy and insolvency‑related events of default with respect to the Company occur, the principal of, and accrued and unpaid interest on, all of the then outstanding 2027 Notes shall automatically become due and payable. If any other event of default occurs and is continuing, the 2027 Trustee by notice to the Company, or the holders of the 2027 Notes of at least 25% in principal amount of the outstanding 2027 Notes by notice to the Company and the 2027 Trustee, may declare the principal of, and accrued and unpaid interest on, all of the then outstanding 2027 Notes to be due and payable. Notwithstanding the foregoing, the 2027 Indenture provides that, to the extent the Company elects, the sole remedy for an event of default relating to certain failures by the Company to comply with reporting covenant in the 2027 Indenture consists exclusively of the right to receive additional interest on the 2027 Notes.

As discussed in Note 2, the Company early adopted ASU 2020‑06 as of January 1, 2021 and concluded the 2027 Notes will be accounted for as debt, with no bifurcation of the embedded conversion feature. Transaction costs were recorded as a direct deduction from the related debt liability in the consolidated balance sheet and are amortized to interest expense using the effective interest method over the term of the 2027 Notes. The effective interest rate for the 2027 Notes is 0.864%.

The 2027 Notes are the Company’s senior, unsecured obligations that rank senior in right of payment to the Company’s future indebtedness that is expressly subordinated to the 2027 Notes, rank equally in right of payment with the Company’s existing and future senior unsecured indebtedness that is not so subordinated (including the Company’s 2026 Notes), effectively subordinated to the Company’s existing and future secured indebtedness (including obligations under the Company’s senior secured credit facilities), to the extent of the value of the collateral securing such indebtedness, and structurally subordinated to all existing and future indebtedness and other liabilities (including trade payables and preferred equity (to the extent the Company is not a holder thereof)) of the Company’s subsidiaries. The 2027 Notes contain both affirmative and negative covenants. As of September 30, 2021, the Company was in compliance with all covenants in the 2027 Notes.

In connection with the pricing of the 2027 Notes, the Company entered into capped call options with certain of the initial purchasers or their respective affiliates and certain other financial institutions. The Company incurred $50 of expenses in connection with the capped call options, which were recorded in Accounts payable in the consolidated balance sheet as of September 30, 2021. The capped call options are expected to reduce potential dilution to the Company’s Class B Common Stock upon any conversion of 2027 Notes and/or offset any cash payments the Company is required to make in excess of the principal amount of converted notes, as the case may be, with such reduction and/or offset subject to a cap. The cap price of the capped call options is initially $95.5575 per share, which represents a premium of 55% above the last reported sale price per share of the Company’s Class B Common Stock on the Nasdaq Global Select Market on June 23, 2021 and is subject to customary adjustments under the terms of the capped call options.

The capped call options were entered into in conjunction with the issuance of the 2027 Notes, however, they are legally separate agreements that can be separately exercised, with the receipt of shares under the capped call options having no effect on the 2027 Notes, and are legally detachable. As the capped call options are both legally detachable and separately exercisable from the 2027 Notes, the Company accounts for the capped call options separately from the 2027 Notes. The capped call options are indexed to the Company’s own common stock and classified in stockholders’ equity. As such, the premiums paid for the capped call options have been included as a net reduction to Additional paid-in capital in the consolidated balance sheet.
