open-market sale financial
"transaction_action: "open-market sale" for common share dispositions"
An open-market sale is when a shareholder sells existing shares directly on a public exchange to any willing buyer, rather than through a private deal. Think of it like putting goods on a busy market stall where price is set by supply and demand; for investors it matters because such sales increase available supply, can put short-term downward pressure on the stock price, and signal changes in liquidity or investor confidence.
Non-Qualifed Stock Options (Right to Buy) financial
"security_title: "Non-Qualifed Stock Options (Right to Buy)" in derivative entries"
weighted average price financial
"footnote states "The price reported is a weighted average price" for sales"
Weighted average price is the average price of a security where each trade or component is counted according to its size, so bigger trades pull the average more than smaller ones. Think of it like calculating the average cost of a grocery haul where items you bought more of have greater influence on the final per-item cost. Investors use it to understand the true average price paid or received, judge execution quality, and compare trading performance against market movement.
Worthington Steel, Inc. 2023 Long Term Incentive Plan financial
"footnotes note options were granted under the "Worthington Steel, Inc. 2023 Long Term Incentive Plan""
non-qualified stock option financial
"footnotes repeatedly describe each award as a "non-qualified stock option""
A non-qualified stock option (NSO) is a contract that lets an employee or service provider buy company shares at a fixed price for a set period, like a voucher to purchase stock later at today’s price. It matters to investors because exercising NSOs creates ordinary income for the holder and can increase share count, affecting a company’s earnings and ownership mix; think of it as a future sale that can dilute existing shareholders and has immediate tax consequences for the recipient.
