These new RSU grants are scheduled to vest in one year, in three years, or over three years, depending on the terms of each grant, with vesting dependent on service requirements for all awards and market-based conditions for certain awards. Each RSU grant will potentially result in the future issuance of one share of the Company’s common stock if the vesting conditions are satisfied; however, RSUs with market-based vesting conditions could vest at rates between 50% and 200%. Under the 2021 BlueLinx Holdings, Inc. 2021 Long-Term Incentive Plan as of June 28, 2025, a net of 273,941 shares of the Company’s common stock remain available for future issuances of equity-based compensation awards.
