Insights

Securities Counsel

Correction to registration fee table; no substantive offering change.

This supplement amends the Calculation of Registration Fee table to include 280,958 shares omitted from the prior prospectus supplement. The filing explicitly limits the change to the fee table and states that no other parts of the prospectus supplement or accompanying prospectus are altered.

Because the amendment is clerical and confined to the fee calculation, material investor rights, proceeds treatment, and offering mechanics are unchanged per the text; stakeholders should see this as an administrative correction.
