Item 7.01

Regulation FD Disclosure.

On May 19, 2026 (the “Call Notice Date”), Granite Construction Incorporated (the “Company”) announced that it called the outstanding $273.3 million aggregate principal amount of the Company’s 3.75% Convertible Senior Notes due 2028 (the “2028 Notes”) for redemption on August 10, 2026. Holders of the 2028 Notes may surrender their 2028 Notes for conversion at any time before the close of business on August 6, 2026. The Company elected to settle conversions on or after the Call Notice Date and through the close of business on August 6, 2026 by paying cash up to $2,617.40 per $1,000 principal amount of the 2028 Notes to be converted and delivering shares of the Company’s common stock, par value $0.01 per share, in respect of the remainder, if any, of the conversion obligation in excess thereof. In accordance with the terms of the Indenture, dated as of May 11, 2023, between the Company and Wilmington Trust, National Association (the “Indenture”), pursuant to which the 2028 Notes were issued, settlement amounts due to holders of the 2028 Notes that validly convert their 2028 Notes before the close of business on August 6, 2026 will be determined by the Company over an observation period consisting of the 50 consecutive trading days beginning on, and including, May 27, 2026 (the “Observation Period”).

The Company has determined that a Market Disruption Event (as defined in the Indenture) occurred on each of July 9 and July 10, 2026, and, accordingly, neither July 9 nor July 10, 2026 are trading days for purposes of the Observation Period. As a result, the Company expects that the Observation Period that began on May 27, 2026 will run through, and include, August 10, 2026 (excluding, for the avoidance of doubt, July 9 and July 10, 2026), subject to any future Market Disruption Events that may occur. The Company expects to settle the conversion of 2028 Notes validly surrendered for conversion in connection with the redemption on August 12, 2026, in accordance with the terms of the Indenture.

Forward-Looking Statements

Any statements contained in this Current Report on Form 8-K that are not based on historical facts, including statements about the Observation Period and the settlement of conversions of the 2028 Notes constitute forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements are identified by words such as “expects,” “estimates,” “intends,” “plans,” “potential,” “may,” “will,” “could,” “would” and the negatives thereof or other comparable terminology or by the context in which they are made. These forward-looking statements are based on management’s current beliefs, assumptions and estimates. These expectations may or may not be realized. Some of these expectations may be based on beliefs, assumptions or estimates that may prove to be incorrect. In addition, the Company’s business and operations involve numerous risks and uncertainties, many of which are beyond the Company’s control, which could result in the Company’s expectations not being realized or otherwise materially affect the Company’s business, financial condition, results of operations, cash flows and liquidity. Such risks and uncertainties include, but are not limited to, those described in greater detail in the Company’s filings with the Securities and Exchange Commission, particularly those described in the Company’s Annual Report on Form 10-K and Quarterly Reports on Form 10-Q.

Due to the inherent risks and uncertainties associated with the Company’s forward-looking statements, the reader is cautioned not to place undue reliance on them. The reader is also cautioned that the forward-looking statements contained herein speak only as of the date of this Current Report on Form 8-K and, except as required by law, the Company undertakes no obligation to revise or update any forward-looking statements for any reason.
