Stock Option financial

"security titled "Stock Option" relating to IMMUNIC common stock"

A stock option is a contract that gives you the right to buy or sell a company's stock at a specific price within a certain time frame. People use them to potentially make money if the stock's price moves favorably or to protect against losses. It's like holding a coupon that can be used to buy or sell stock at a set price later on.

beneficial ownership regulatory

"the Reporting Person disclaims beneficial ownership of the securities"

Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.

pecuniary interest financial

"except to the extent of his pecuniary interest therein, if any"

economic benefit financial

"obligated to transfer the economic benefit, if any, received upon the sale"

Section 16 of the Securities Exchange Act of 1934 regulatory

"for purposes of Section 16 of the Securities Exchange Act of 1934"

A provision of federal securities law that requires company insiders—directors, officers and large shareholders—to publicly report their stock holdings and trades and to surrender any “short-swing” profits from purchases and sales within a six-month window. It acts like a rule that forces leaders to announce their trades and prevents quick buy-sell windfalls, giving investors transparency into insider activity and reducing opportunities for unfair gain.
