3.75% Convertible Notes

On May 11, 2023, we issued $373.8 million aggregate principal amount of our 3.75% Convertible Notes. The 3.75% Convertible Notes bear interest at a rate of 3.75% per annum payable semiannually in arrears on May 15 and November 15 of each year, beginning on November 15, 2023 and mature on May 15, 2028, unless earlier converted, redeemed or repurchased. Prior to the close of business on the business day immediately preceding November 15, 2027, the 3.75% Convertible Notes will be convertible at the option of the holders only upon the occurrence of certain events and during certain periods. Thereafter, the 3.75% Convertible Notes will be convertible at the option of the holders at any time until the close of business on the second scheduled trading day immediately preceding the maturity date.

The initial conversion rate applicable to the 3.75% Convertible Notes is 21.6807 shares of Granite common stock per $1,000 principal amount of the 3.75% Convertible Notes, which is equivalent to an initial conversion price of approximately $46.12 per share of Granite common stock, subject to adjustment if certain events occur. Upon conversion, we will pay or deliver, as the case may be, cash, shares of Granite common stock or a combination of cash and shares of Granite common stock, at our election. In addition, upon the occurrence of a “fundamental change” as defined in the indenture governing the 3.75% Convertible Notes, holders may require us to repurchase for cash all or any portion of their 3.75% Convertible Notes at a fundamental change repurchase price equal to 100% of the principal amount of the 3.75% Convertible Notes to be repurchased plus any accrued and unpaid interest to, but excluding, the fundamental change repurchase date. If certain corporate events that constitute a “make-whole fundamental change” as set forth in the indenture governing the 3.75% Convertible Notes occur prior to the maturity date of the 3.75% Convertible Notes 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 3.75% Convertible Notes in connection with such event or notice of redemption.

We will not be able to redeem the 3.75% Convertible Notes prior to May 20, 2026. On or after May 20, 2026, we have the option to redeem for cash all or any portion of the 3.75% Convertible Notes if the last reported sale price of our common stock is equal to or greater than 130% of the conversion price for a specified period of time at a redemption price equal to 100% of the principal amount of the 3.75% Convertible Notes to be redeemed, plus any accrued but unpaid interest to, but excluding, the redemption date. In addition, as described in the indenture governing the 3.75% Convertible Notes, certain events of default including, but not limited to, bankruptcy, insolvency or reorganization, may result in the 3.75% Convertible Notes becoming due and payable immediately.

The net proceeds from the sale of the 3.75% Convertible Notes were approximately $364.4 million, after deducting the initial purchasers’ discount. We used approximately $53.0 million of the net proceeds from the offering to pay the cost of the Capped Call Transactions (as described below). In addition, we used approximately $198.8 million of the net proceeds and issued 1,390,500 shares of Granite common stock in exchange for approximately $198.7 million aggregate principal amount of our 2.75% Convertible Notes concurrent with the offering in separate and individually negotiated transactions. We also received 1,390,516 shares from bond option counterparties for the exercise of our bond hedge, corresponding to the portion of the 2.75% Convertible Notes that were exchanged, and used approximately $13.2 million of the net proceeds to pay the cost of terminating the portion of the existing warrant transactions that correspond to the 2.75% Convertible Notes exchanged.

Capped Call Transactions

In May 2023, we entered into capped call transactions (the "Capped Call Transactions") in connection with the offering of the 3.75% Convertible Notes. The Capped Call Transactions are expected generally to reduce the potential dilution to Granite’s common stock upon conversion of the 3.75% Convertible Notes and/or offset any cash payments Granite is required to make in excess of the principal amount of converted 3.75% Convertible Notes, as the case may be. If, however, the market price per share of Granite’s common stock, as measured under the terms of the Capped Call Transactions, exceeds the cap price of the Capped Call Transactions, there would nevertheless be dilution and/or there would not be an offset of such cash payments, in each case, to the extent that such market price exceeds the cap price of the Capped Call Transactions.

The cap price of the Capped Call Transactions will initially be $79.83 per share, which represents a premium of 125% over the last reported sale price of Granite’s common stock of $35.48 per share on the New York Stock Exchange on May 8, 2023, and is subject to certain adjustments under the terms of the Capped Call Transactions.

2.75% Convertible Notes

The 2.75% Convertible Notes were issued in November 2019 in an aggregate principal amount of $230.0 million, with an interest rate of 2.75% and a maturity date of November 1, 2024, unless earlier converted, redeemed or repurchased. The 2.75% Convertible Notes are convertible at the option of the holders prior to the close of business on the business day before May 1, 2024 only during certain periods and upon the occurrence of certain events. After May 1, 2024, the 2.75% Convertible Notes will be convertible at the option of the holders at any time until the close of business on the second scheduled trading day immediately preceding the maturity date. The conversion rate applicable to the 2.75% Convertible Notes is 31.7776 shares of Granite common stock per $1,000 principal amount of 2.75% Convertible Notes, which is equivalent to a conversion price of approximately $31.47 per share of Granite common stock. Upon conversion, we will pay or deliver, as the case may be, cash, shares of Granite common stock or a combination of cash and shares of Granite common stock, at our election. In addition, upon the occurrence of a “make-whole fundamental change” as defined in the indenture governing the 2.75% Convertible Notes prior to the maturity date of the 2.75% Convertible Notes or if the Company delivers a notice of redemption, we will, in certain circumstances, increase the conversion rate for a holder that elects to convert its 2.75% Convertible Notes in connection with such a make-whole fundamental change or notice of redemption.

We have the option to redeem for cash all or any portion of the 2.75% Convertible Notes if the last reported sale price of our common stock is equal to or greater than 130% of the conversion price for a specified period of time at a redemption price equal to 100% of the principal amount of the 2.75% Convertible Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. Upon the occurrence of a “fundamental change” as defined in the indenture governing the 2.75% Convertible Notes, holders may require us to repurchase for cash all or any portion of their 2.75% Convertible Notes at a price equal to 100% of the principal amount of the 2.75% Convertible Notes to be repurchased plus any accrued and unpaid interest to, but excluding, the fundamental change repurchase date. In addition, as described in the indenture governing the 2.75% Convertible Notes, certain events of default including, but not limited to, bankruptcy, insolvency or reorganization, may result in the 2.75% Convertible Notes becoming due and payable immediately.

At September 30, 2023, $31.3 million remained outstanding of our 2.75% Convertible Notes.

Credit Agreement

In June 2022, we entered into the Credit Agreement which matures on June 2, 2027. The Credit Agreement is a $350.0 million senior secured, five-year revolving facility (the “Revolver”), including an accordion feature allowing us to increase borrowings up to the greater of (a) $200.0 million and (b) 100% of twelve-month trailing consolidated EBITDA, subject to lender approval. The Credit Agreement includes a $150.0 million sublimit for letters of credit ($75.0 million for financial

letters of credit) and a $20.0 million sublimit for swingline loans. In May 2023, we entered into Amendment No. 1 to the Credit Agreement (the "Amendment"). The Amendment amended the Credit Agreement to, among other things, permit the Company to exchange its 2.75% Convertible Notes for cash and shares of its common stock and to clarify that (i) the issuance of the 3.75% Convertible Notes was permitted under the terms of the Credit Agreement and (ii) that a Swap Contract (as defined in the Credit Agreement) does not include any Permitted Call Spread Transaction (as defined in the Credit Agreement).

As of September 30, 2023, the total unused availability under the Credit Agreement was $330.8 million, resulting from $19.2 million in issued and outstanding letters of credit and nothing drawn under the Revolver. The letters of credit had expiration dates between November 2023 and December 2026.

The Credit Agreement contains certain affirmative and restrictive covenants, and customary events of default. The financial covenants include a maximum Consolidated Leverage Ratio (as defined in the Credit Agreement) and a minimum Consolidated Interest Coverage Ratio (as defined in the Credit Agreement). As of September 30, 2023, we were in compliance with the covenants in the Credit Agreement.

Debt Issuance Costs

During the three and nine months ended September 30, 2023, we recorded $0.6 million and $3.0 million, respectively, of amortization related to debt issuance costs. This included $1.7 million of accelerated amortization of debt issuance costs associated with the 2.75% Convertible Notes that were repaid and are included in the loss on debt extinguishment for the nine months ended September 30, 2023. We also capitalized $10.0 million in third party offering costs related to the issuance of the 3.75% Convertible Notes for the nine months ended September 30, 2023. These debt issuance costs will be amortized over the expected life of the 3.75% Convertible Notes.

During the three and nine months ended September 30, 2022, we recorded $0.3 million and $1.0 million, respectively, of amortization related to debt issuance costs.
