Insights

Institutional Ownership Analyst

T. Rowe Price reports an 11.8% stake in Lattice Semiconductor

The filing shows 16,083,095 shares beneficially owned with 15,860,828 shares carrying sole voting power. This is a large passive holding disclosure typical for investment managers reporting under Schedule 13G/A rather than an active acquisition filing.

Pay attention to subsequent amendments or Forms if voting or disposition powers change; the filing itself contains a denial that the filer is the beneficial owner.

Compliance Counsel

Amendment and denial language reflect standard fiduciary reporting practice

The document is an amended Schedule 13G reporting ownership and includes an express statement denying beneficial ownership. Such language is common when an investment manager reports holdings while disclaiming beneficial ownership claims.

Future filings may clarify any shifts in voting/dispositive power; current cash‑flow treatment is not part of this disclosure.

Schedule 13G/A regulatory

"Amendment No. 3) 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 regulatory

"Amount beneficially owned: 16083095 (b) Percent of class: 11.8 %"

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 16,083,095.00"

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.

sole voting power regulatory

"Sole Voting Power 15,860,828.00"

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.
