FAQ

What insider transactions did FOSTER L B CO (FSTR) report for Sean M. Reilly?

The filing reports two tax-withholding dispositions of common stock by Controller Sean M. Reilly, totaling 1,048 shares at $31.63 per share. These arose from restricted stock vesting under long-term incentive plans, rather than open-market buying or selling activity.

Why were FSTR shares disposed of in Sean M. Reilly’s Form 4/A filing?

Shares were disposed of to pay taxes on vesting restricted stock awards. Footnotes state the shares were withheld to satisfy tax liabilities tied to long-term incentive plan awards, a common administrative mechanism rather than a discretionary open-market sale of L.B. Foster stock.

How many FSTR shares were involved in the February 2026 tax-withholding transactions?

The transactions involved 686 shares of common stock on February 14, 2026 and 362 shares on February 13, 2026. Both were priced at $31.63 per share and classified as tax-withholding dispositions related to vesting restricted stock awards.

What is Sean M. Reilly’s FSTR share ownership after the reported transactions?

What long-term incentive awards are mentioned in the FSTR Form 4/A footnotes?

Footnotes reference performance restricted stock units from the 2023–2025 and 2024–2026 Long Term Incentive Plans. They state 6,614 units and 859 units respectively, which will settle after performance periods end, following Compensation Committee certification of results.

Why was this FOSTER L B CO Form 4/A filed as an amendment?

The Form 4/A was filed to correct the number of shares previously reported as withheld for taxes on restricted stock vesting under the 2023–2025 LTIP. A footnote explains the amendment adjusts the earlier count of tax-withheld shares from that prior award.
