4 terms

open-market purchase financial

"transaction_action": "open-market purchase""

An open-market purchase is when an investor or a company buys shares on a public stock exchange at the going market price, rather than through a private deal. It matters to investors because these purchases change how many shares are available, can push the stock price up or signal confidence from large buyers, and often affect per-share metrics like earnings—think of it like someone buying lots of apples off a grocery shelf, reducing supply and potentially raising the price.

restricted stock units financial

"Restricted stock units granted under the HF Sinclair Corporation Amended"

Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.

Long Term Incentive Plan financial

"under the HF Sinclair Corporation Amended and Restated 2020 Long Term Incentive Plan"

A long term incentive plan is a company program that awards executives and key employees bonuses—often in stock, options, or cash—only if the business meets multi-year performance goals. It links management pay to company results—like tying a coach’s bonus to a team’s multi-season record—so investors monitor it for how leaders are motivated, potential share dilution, and signals about the company’s long-term priorities.

weighted average price financial

"The price reported is a weighted average price."

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.
