Insights

Institutional Ownership Analyst

Joint disclosure shows concentrated institutional holdings near 5–6% each.

The filing lists three related reporting persons with overlapping positions: Westchester, Virtus, and The Merger Fund. Each holds between 625,033 and 680,000 shares, with shared voting/dispositive arrangements reflecting adviser/sub-adviser relationships.

Key dependencies include the 11,500,000 shares outstanding as of March 16, 2026 anchor and the reporting persons' allocation of sole versus shared powers; subsequent filings would show any material changes to these percentages.

Corporate Governance Specialist

Shared control among adviser entities suggests coordinated reporting, not independent block holders.

The disclosure explains that Virtus is adviser to the funds and Westchester is sub-adviser, which accounts for overlapping shared voting and dispositive power entries. The Merger Fund’s holdings are included within the adviser aggregates.

Investors reviewing governance should note the joint filing structure and that voting power is largely shared, as specified in the ownership table.

4 terms

beneficially owned regulatory

"Amount beneficially owned: Westchester Capital Management, LLC: 680,000"

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.

shared dispositive power regulatory

"Shared Dispositive Power 646,288.00"

CUSIP market

"CUSIP Number(s): G86880104"

A CUSIP is a nine-character alphanumeric code that uniquely identifies a U.S. or Canadian financial security—such as a stock, bond, or fund share—like a Social Security number for an investment. It matters to investors because brokers, exchanges and record-keepers use the CUSIP to match trades, track ownership, settle transactions and pull accurate records, reducing errors and ensuring money and securities go to the right place.

Schedule 13G regulatory

"This statement is being filed jointly by the following"

A Schedule 13G is a formal document that investors file with the government when they acquire a large ownership stake in a company, usually for investment purposes rather than control. It helps keep the public informed about who owns significant parts of a company's shares, which can influence how the company is managed and how investors make decisions. Filing this schedule is important for transparency and understanding the ownership landscape of publicly traded companies.
