Form 144 regulatory

"Filer Information | | | 144: Filer Information"

Form 144 is a document that investors must file with the government when they plan to sell a large number of shares of a company's stock. It helps ensure transparency so everyone knows how many shares are being sold and when, which can impact the stock's price.

broker assisted cashless exercise financial

"5000 | 08/03/2026 | Broker assisted cashless exercise"

performance share award financial

"02/05/2026 | Vesting of performance share award | Alkermes plc."

A performance share award is a type of executive or employee pay that grants company stock only if predefined performance goals are met over a set period. Think of it as a bonus paid in shares—similar to a savings payout that arrives only if certain targets are hit—so it aligns management incentives with company results and can affect future share count and shareholder value. Investors watch these awards because they influence executive behavior, potential dilution of shares, and signals about expected performance.

restricted stock unit awards financial

"02/23/2026 | Vesting of restricted stock unit awards"

Restricted stock unit awards are company promises to deliver a specific number of shares to employees or service providers in the future once conditions—such as staying with the company for a set time or meeting performance targets—are met. They matter to investors because when the promises convert into actual shares they increase the total share count and can reduce earnings per share, while also aligning recipients’ interests with stock performance much like deferred pay that turns into ownership if goals are met.

equity compensation plan financial

"Granted as part of issuer equity compensation plan"

A plan by which a company gives employees, directors or contractors ownership or the right to buy ownership in the company through stock, options or similar awards — think of promising slices of the company pie as part of someone's pay. It matters to investors because these awards can change the number of shares outstanding, affect reported profits and influence management’s decisions; large or generous plans can dilute existing holders and alter incentives over time.
