indirect controlling shareholder financial

"holds these shares indirectly through an indirect controlling shareholder of the issuer"

pecuniary interest financial

"disclaims beneficial ownership of such shares except to the extent of his pecuniary interest"

beneficial ownership financial

"shall not be deemed an admission of beneficial ownership of all of the reported shares"

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.

Section 16 regulatory

"for purposes of Section 16 or for any other purpose"

Section 16 is a U.S. securities law rule that governs the trading and disclosure obligations of company insiders — typically officers, directors and large shareholders — to promote transparency and deter unfair profit-taking. It requires insiders to publicly report their stock trades and allows companies or the issuer to reclaim quick, short-term profits from certain insider trades, like a scoreboard and a refund policy that help investors see and limit possible insider advantage.

Remarks:

This Form 3/A (this "Amendment") amends the Form 3 filing dated Marh 18, 2026 (the "Original Form 3"), which inadvertently overstated the reporting person's indirect ownership of the issuer's preferred shares. The preferred shares indirectly owned by the reporting person, as reported in this Amendment, reflects the correct amount and forms of ownership of all preferred shares indirectly owned by the reporting person as of the filing date of the Original Form 3.
