Insights
Dimensional reports a sub-5% passive stake through client Funds, a routine disclosure for large managers.
The filing lists 1,956,477 shares representing 4.8% of Heritage Financial's common stock as of 03/31/2026. Voting and dispositive powers are exercised in Dimensional's advisory role for pooled Funds.
Because the stake is below 5% per-fund thresholds and Dimensional disclaims beneficial ownership, this is a standard Section 13 filing reflecting asset-management positions; it is not a corporate-control signal.

"Amendment No. 1) Heritage Financial Corp/WA 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 ownershipfinancial
"Amount beneficially owned: 1,956,477 ** see Note 1 **"
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.
investment adviserregulatory
"Dimensional Fund Advisors LP, an investment adviser registered under Section 203"
An investment adviser is a person or firm that professionally manages money and gives recommendations about buying, selling, or holding investments. Like a financial coach or guide, they have a legal duty to act in a client's best financial interest, so their advice, fees and potential conflicts can directly affect returns and risk — making their role important for investors who want informed, accountable help with portfolios.
