Rule 10b5-1 trading plan regulatory

"Shares sold pursuant to a Rule 10b5-1 trading plan adopted by the reporting person."

A Rule 10b5-1 trading plan is a pre-arranged schedule that allows company insiders to buy or sell stock at specific times, even if they have inside information. It helps prevent accusations of unfair trading by making these transactions look planned and transparent, rather than sneaky or illegal.

unitized stock fund financial

"share equivalents held by the reporting person in the unitized stock fund included in the Ameren Corporation Savings Investment Plan"

dividend equivalents financial

"Amount includes 573 accrued dividend equivalents acquired during the first quarter of 2026"

Payments tied to employee or contractor equity awards that mirror the cash dividends paid on the company’s stock; they give the holder the same economic benefit as owning the shares without transferring actual shares—often paid in cash or additional award units when the award becomes payable. Investors care because these payments affect a company’s compensation costs, cash flow and potential share dilution, and they signal how management is being rewarded and aligned with shareholders.

restricted stock units financial

"dividend reinvestment feature of restricted stock units granted under the issuer's 2022 Omnibus Incentive Compensation Plan"

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.

Omnibus Incentive Compensation Plan financial

"restricted stock units granted under the issuer's 2022 Omnibus Incentive Compensation Plan"

An omnibus incentive compensation plan is a single, flexible program that lets a company grant different kinds of pay — such as cash bonuses, stock options, restricted stock, or performance awards — to employees, executives and directors. Investors care because the plan affects how much ownership can be given away (dilution), how much the company spends on pay, and whether executives’ goals are aligned with shareholders, much like a menu that decides what rewards staff can pick and how costly they are.
