The filing lists 1,093,338.54 shares as beneficially owned and classifies the position as ownership of 5 percent or less. This form is a passive disclosure used by large investment managers.

Cash‑flow treatment and trading intent are not stated in the excerpt; subsequent filings could clarify voting or disposition authority if material changes occur.

Compliance / SEC Filings Specialist

The amendment confirms standard Schedule 13G reporting and references a 13d-1(k)(1) agreement.

Item responses show sole dispositive power of 1,093,338.54 shares and sole voting power of 1,091,535 on the cover lines. The schedule includes Exhibit 99 and a Power of Attorney reference for signature authority.

Schedule 13G/A regulatory

"Amendment No. 5 and header identifying 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.

beneficially owned regulatory

"Item 4(a) Amount beneficially owned: 1093338.54"

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.

13d-1(k)(1) agreement regulatory

"Please see Exhibit 99 for 13d-1(k)(1) agreement"

sole dispositive power regulatory

"Sole Dispositive Power 1,093,338.54"

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.
