Common Units Representing Limited Partner Interests financial

"Title of Class of Securities: Common Units Representing Limited Partner Interests"

beneficial owner financial

"Delek Services is the record and beneficial owner of 10,462,963 Common Units"

A beneficial owner is the person who ultimately owns or controls a financial asset or property, even if their name isn't directly on official documents. Think of it like someone who secretly holds the keys to a safe deposit box—others may appear to have access, but the true owner is the one who benefits from what's inside. Identifying beneficial owners helps ensure transparency and prevent illegal activities like money laundering or fraud.

Common Unit Purchase Agreement financial

"pursuant to that certain Common Unit Purchase Agreement (the "Purchase Agreement") dated as of February 24, 2025"

Asset Purchase Agreement financial

"pursuant to an asset purchase agreement dated January 30, 2026, by and between Delek and the Issuer"

An asset purchase agreement is a legal contract in which a buyer agrees to buy specific assets and contracts of a business rather than buying the company’s stock or ownership. It matters to investors because it determines exactly what is being bought and what liabilities stay behind — like buying the furniture and equipment from a store but not the building or past debts — which affects the deal’s value, taxes and future risk exposure.

Schedule 13D regulatory

"If the filing person has previously filed a statement on Schedule 13G to report the acquisition"

A Schedule 13D is a legal document that investors file with regulators when they buy a large enough stake in a company to potentially influence its management or decisions. It provides details about the investor’s intention, ownership stake, and plans, helping other investors understand who is gaining control and what their motives might be.

Percent of class financial

"Percent of class represented by amount in Row (11) 63.0 %"

Percent of class is the portion of a specific category of securities—such as a company’s common shares, preferred shares, or a bond series—that takes part in or approves a corporate action (vote, consent, tender, etc.). Investors watch this number because it reveals how much support or opposition exists within that particular shareholder group; like counting how many members of a club back a proposal, it can determine whether a plan passes or how influence is distributed.
