Rhea-AI Filing Summary

FOSTER L B CO EVP & CFO William M. Thalman reported equity award activity involving performance stock units and common shares.

As part of this event, 817 common shares were disposed of at $31.54 per share to cover tax withholding, characterized as a payment of tax liability by delivering securities rather than an open-market sale.
