DLH Holdings Corp. provided revenue guidance for the fourth quarter of 2023. The preliminary estimate of revenue for the fiscal 2023 fourth quarter is approximately $100 million versus $67.2 million in the prior-year period.

The increase was primarily driven by contributions from GRSi. The company's legacy contract portfolio grew moderately to offset the completion of short-term contracts associated with the COVID-19 pandemic response in fiscal 2022.
