Yes, I think the logic holds for horizontal mergers too, especially when the companies are similar in size and operate in the same market. High strategic interdependence often means shared customers, overlapping operations, and a need for unified branding and systems—so full integration makes sense.
That said, the most challenging part is often cultural integration. Even when companies look similar on paper, differences in leadership style, decision-making, or internal norms can derail progress. Aligning people and processes without losing momentum or morale is where the real risk lies.
Curious to hear how others have navigated this—especially in peer-to-peer integrations.
