Insights

Institutional Ownership Analyst

BlackRock reports an 8.7% stake in Alexandria REIT held across reporting business units.

The Schedule 13G/A shows 15,113,497 shares beneficially owned as of 03/31/2026, with voting and dispositive powers concentrated in BlackRock business units. This reflects passive/large‑holder reporting rather than an active control filing.

Key dependencies include whether ownership changes in future amendments; subsequent filings will show increases or disposals that could alter leverage or activist risk.

Schedule 13G/A regulatory

"Amendment No. 18 to Schedule 13G/A reporting ownership"

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.

Beneficially owned regulatory

"Amount beneficially owned: 15113497"

Beneficially owned describes securities or assets where a person has the economic rights and control—such as the right to receive dividends and to direct voting—even if legal title is held in another name. Think of it like having the keys and using a car that’s registered to someone else: you get the benefits and make decisions. Investors care because beneficial ownership reveals who truly controls value and voting power, affecting corporate decisions and takeover dynamics.

Dispositive power regulatory

"Sole power to dispose or to direct the disposition of: 15113497"

Dispositive power is the authority to decide the final outcome of an asset, legal claim, contract, or corporate action — in effect the power to dispose of or resolve something. For investors it matters because whoever holds that authority can determine who gets paid, who controls an asset or vote, and how risks and returns are allocated; think of it like holding the key that lets you lock in the winner or loser in a deal.
