Development Milestone financial

"in connection with the first Development Milestone payment"

License Agreement regulatory

"as defined in Section 6.2(a) of the License Agreement"

A license agreement is a contract where the owner of intellectual property, technology, a brand, or other rights gives another party permission to use those assets under specified conditions, usually for fees, royalties or other payments. For investors it matters because such deals create or limit predictable revenue streams, affect profit margins, transfer legal and commercial risk, and can determine how quickly a company can grow — like renting out a patented tool to earn steady income while keeping ownership.

broker commission financial

"transferred by the Reporting Person to LifeSci Advisors, LLC as broker commission"

beneficially owned financial

"Reflects 2,857,480 shares of Common Stock beneficially owned"

Beneficially owned describes securities or assets where a person has the economic rights and control—such as the right to receive dividends and to direct voting—even if legal title is held in another name. Think of it like having the keys and using a car that’s registered to someone else: you get the benefits and make decisions. Investors care because beneficial ownership reveals who truly controls value and voting power, affecting corporate decisions and takeover dynamics.
