+We are making it easier to view and manage all subsidiaries of a parent company directly from the Codat Portal.
+
+<!--truncate-->
+
+## What's new?
+
+On **April 30, 2026**, we are adding a new **Subsidiaries** view to parent companies in the [Codat Portal](https://app.codat.io). When you open a parent company, you will see a dedicated Subsidiaries page that lists all of its child companies in one place, with the same controls you already use on the top-level Companies page.
+
+![Subsidiaries view for a parent company](/img/updates/260430-subsidiaries-page.gif)
+
+We are introducing the following improvements:
+
+- New **Subsidiaries** sidebar item is added to any company that has subsidiaries, with a count indicator showing how many child companies it has.
+- Dedicated subsidiaries table reuses the familiar Companies table, including search, sort, connection-status filter, and infinite scroll.
+- Edit, delete, and link actions are available directly from each subsidiary row, matching the behavior on the top-level Companies page.
+
+These improvements apply to all parent companies in the Portal and complement the [hierarchical company table](/blog/multi-entity-portal-update) we shipped earlier this year.
+
+## Who is this relevant for?
+
+This update benefits all customers who manage multi-entity companies, and is especially useful for enterprise clients working with deep parent–child hierarchies who need to drill into a specific parent and manage its subsidiaries without losing context.
+
+## How to get started?
+
+No action is required to benefit from this update. Open any parent company in the [Codat Portal](https://app.codat.io) from **April 30, 2026** and select **Subsidiaries** in the sidebar to view its child companies.
