Insights

Institutional Ownership Analyst

Large passive position disclosed: 16,243,449 shares (11.9% of class).

The filing lists 16,243,449 shares as the amount beneficially owned and 16,203,117 as sole voting power. This indicates substantial voting influence and dispositive capacity recorded in the amendment's ownership table.

Because the statement expressly denies beneficial ownership, the economic/strategy interpretation is limited; subsequent filings or registrant disclosures may clarify whether holdings are managed on behalf of separate accounts.

Governance & Proxy Advisor

Schedule 13G/A regulatory

"Amendment No. 5 ) LATTICE SEMICONDUCTOR CORP 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 financial

"Amount beneficially owned: 16243449 (b) Percent of class: 11.9 %"

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 dispositive power regulatory

"Sole Dispositive Power 16,243,449.00"

Sole dispositive power is the exclusive legal authority to decide what happens to a security — for example, whether to sell, transfer, or retain shares — without needing anyone else’s permission. Investors care because it signals who truly controls the economic outcome of an investment: like holding the only key to a safe, the holder can realize gains or losses and may trigger regulatory reporting, insider rules, or influence over corporate ownership.
