Key Terms

Schedule 13G/A, Beneficial ownership, Sole/Shared Voting Power

3 terms

Schedule 13G/A regulatory

"Amendment No. 3 ) Exponent Inc Common Stock"

A Schedule 13G/A is an amended public filing with the U.S. securities regulator that updates a previous Schedule 13G, disclosing when an individual or group holds a substantial (typically over 5%) stake in a company and is claiming a passive, non‑controlling intent. Investors monitor these updates because rising or falling holdings can signal changing confidence, potential future moves, or shifts in voting power — like watching a public ledger where large shareholders quietly adjust their positions.

Beneficial ownership regulatory

"Amount beneficially owned: 3,886,546 (b) Percent of class: 7.9 %"

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.

Sole/Shared Voting Power regulatory

"Sole Voting Power 2,839,655.00 Shared Voting Power 1,042,670.00"
