BIO-key International, Inc. provided earnings guidance for the fiscal 2021. The company currently expect full year revenues to range between $8 million and $12 million, with possible upside related to the pace of African contracts, which remain difficult to project. The mid-point of this range would represent growth of more than 250% over fiscal 20220 revenue and approximately 150% over fiscal 2020 second half revenue annualized, as the second half included the full benefit of PortalGuard acquisition.
