beneficial ownership financial

"The information required by this Item 4(a) is set forth in Row 9..."

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.

Mandatory Convertible Preferred Stock financial

"Shares issuable upon conversion of the Company's 7.00% Series A Mandatory Convertible Preferred Stock"

A mandatory convertible preferred stock is a type of investment that pays regular income like a preferred share but is designed to automatically turn into a set number of common shares at a future date, much like a timed coupon that becomes company ownership. It matters to investors because it combines a near-term income stream with a guaranteed future increase in the company’s share count, which can dilute existing owners and change earnings-per-share and voting balance.

Depositary Shares financial

"Preferred Stock represented by depositary shares (the "Depositary Shares")"

Depositary shares are tradable certificates that represent a fractional piece of a larger security held by a third-party bank, like owning a slice of a single big pie instead of the whole pie. They let companies issue and investors buy smaller, more affordable portions of preferred stock or other instruments; holders usually receive proportional dividends and market pricing similar to ordinary shares, but may have limited voting rights and different liquidity or tax implications, which can affect income and resale value.

sole voting power financial

"5 | Sole Voting Power 8,805,130.00 6 | Shared Voting Power 33,379,848.00"

Sole voting power is the exclusive right to cast votes attached to a shareholder’s stock without needing approval from anyone else. Like holding the only remote control for a TV, it lets that holder decide corporate matters such as board members, mergers, and policy changes, making it important to investors because it concentrates control and can strongly influence a company’s strategy and the value of its shares.

dispositive power financial

"Sole Dispositive Power 8,805,130.00 8 | Shared Dispositive Power 33,379,848.00"

Dispositive power is the authority to decide the final outcome of an asset, legal claim, contract, or corporate action — in effect the power to dispose of or resolve something. For investors it matters because whoever holds that authority can determine who gets paid, who controls an asset or vote, and how risks and returns are allocated; think of it like holding the key that lets you lock in the winner or loser in a deal.
