Insights

Institutional Ownership Analyst

Holds and reports sub‑5% passive ownership by advisory accounts.

The filing lists 607,252 shares (4.8%) under shared voting and dispositive power for advisory Accounts managed by Sit Investment Associates and its subsidiary Sit Fixed Income Advisors II. The 12,708,275 shares outstanding as of December 31, 2025 is used to calculate the percent.

Ownership is reported under Schedule 13G/A with a Rule 13d-4 disclaimer; this signals passive/advisory reporting rather than an active acquisition. Subsequent filings would show any change in percent held.

Compliance/Regulatory Specialist

Filing follows passive investor disclosure norms and includes the Rule 13d-4 disclaimer.

The registrants state shared voting and dispositive authority over the shares held by client Accounts and explicitly disclaim beneficial ownership under Rule 13d-4. The cover pages show the percent calculation basis.

From a compliance angle, this amendment updates ownership figures and preserves the passive reporting status; any future change in voting/investment power would require amended disclosure.

Schedule 13G/A regulatory

"Amendment No. 1 to a 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.
