Insights

SEC Compliance Specialist

Filing is a routine Schedule 13G/A joint ownership disclosure under passive/investor reporting rules.

The amendment reports shared voting and dispositive power over 1,000,000 shares (4.3%) using the issuer's stated outstanding share count as of March 27, 2026. The filing includes the customary disclaimer that the Reporting Persons "disclaim beneficial ownership" except for pecuniary interest.

Timing and thresholds matter for reporting class changes; subsequent filings would be required if ownership crosses the 5% passive threshold or changes character.

Corporate Governance Analyst

Shared voting/dispositive power is shown but ownership remains under 5% per the issuer's outstanding count.

The report shows shared voting and dispositive power of 1,000,000 shares for each Reporting Person, which the filing ties to the Master Fund relationship. The joint filing statement is signed by Robin Shah.

Stake size (4.3%) is below common 5% passive thresholds that trigger different disclosure forms; holder intent and any change in control are not stated here.

shared voting power regulatory

"Shared Voting Power 1,000,000.00"

Shared voting power occurs when two or more parties jointly have the right to vote or decide how a block of company shares is cast, like co-owners who must agree before moving a piece of furniture. Investors care because who controls voting rights affects board elections, major corporate decisions and takeover outcomes, and shared control can alter regulatory disclosures and the practical influence any holder has over a company’s direction and value.

beneficially owned regulatory

"Amount beneficially owned: Tenor Capital Management Company, L.P. - 4.3%"

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.

Schedule 13G/A regulatory

"Form type: SCHEDULE 13G/A"

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.
