5 terms

Disposition to issuer regulatory

"transaction code description: Disposition to issuer"

reincorporation merger regulatory

"effective time of the reincorporation merger between Webster and Webster Virginia"

A reincorporation merger is a corporate action where a company creates or uses a new legal entity in a different jurisdiction and merges the old company into it, effectively changing its legal “home.” For investors it matters because the new legal address can alter taxes, shareholder rights, regulatory requirements and listing rules—think of it like a household moving to a new state where different laws and costs apply; the move can change paperwork, investor protections and potential long‑term value.

American Depositary Shares financial

"receive from Banco Santander 2.0548 Banco Santander American Depositary Shares"

American depositary shares (ADSs) are a way for investors in the United States to buy shares of foreign companies without dealing with international markets directly. They represent ownership in a foreign company's stock and are traded on U.S. stock exchanges, making it easier for American investors to buy, sell, and own parts of companies from around the world.

Transaction Agreement regulatory

"Disposed of pursuant to the transaction agreement dated February 3, 2026"

A transaction agreement is a legal contract that lays out the terms and steps for a specific business deal—such as a merger, acquisition, asset sale, financing, or securities purchase. It defines what each party must do, what is being exchanged, conditions that must be met, and how disputes are handled. For investors it matters because this document determines the rights, timing, risks, and potential payments they can expect from the deal, much like a recipe and schedule that guides a complex group project.

beneficially owns regulatory

"the reporting person no longer beneficially owns, directly or indirectly, any shares"

Beneficially owns means a person or entity enjoys the economic benefits and control of a security even if the legal title or registration is held in another name. Think of it like having the keys and profits from a car that is registered to a friend: you use it, benefit from it, and make decisions about it even though the official paperwork lists someone else. For investors, this matters because it reveals who truly controls shares, affects voting power, potential conflicts of interest, and regulatory disclosure obligations.
