beneficial ownership financial

"The Reporting Person disclaims beneficial ownership of the reported 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 its pecuniary interest therein"

director by deputization regulatory

"may be deemed to be a director by deputization of the Issuer"

indirect ownership financial

"The reported securities are held directly by Sumitomo Mitsui Banking Corporation"
