When a Public Company Buys Another, Does the Purchasing Company's Stock Typically Drop?

The acquisition of one company by another can be a complex and multifaceted process. While some acquisitions can lead to significant strategic benefits for the purchasing company, others may not meet the desired outcomes. This article delves into the typical impact on the stock prices of purchasing companies following an acquisition, drawing from existing literature and practical observations.

The Typical Impact on Stock Prices

The notion that the purchasing company's stock price typically drops after acquiring another company is a common misconception. Let's explore some of the scenarios in which this could occur and others where the stock price might rise.

Synergies and Strategic Benefits

The purchasing company's stock price may rise if the acquired company directly and immediately adds synergies to the purchasing company. This can involve several strategies:

Enters New Business Segments: The acquired company can introduce the purchasing company to new markets or products that complement its existing portfolio. Negotiates Lower Costs: Vertical integration can help lower costs for the purchasing company by streamlining supply chains or production processes. Brings New Technologies: Acquiring a company known for its technological innovations can help the purchasing company stay competitive and drive future growth. Expands Product Portfolio: Adding a new product line from the acquired company can diversify the purchasing company's offerings and increase overall revenue.

These strategic benefits can lead to increased shareholder value, often resulting in a rise in the purchasing company's stock price.

Contingent Liabilities and Deeper Integration Risks

However, there are instances where the purchasing company's stock price may drop in the aftermath of an acquisition. This can happen due to several factors:

Excessive Purchase Price: Sometimes, the acquiring company pays more than what the acquired company is truly worth. Required Cultural Changes: Enforcing major business and cultural changes on the acquired company can lead to cultural conflicts and ultimately undermine the acquired company's success. Top Talent Exits: Key employees in the acquired company may leave due to financial incentives or a mismatch in company culture, leading to a loss of valuable expertise. Strained Business Models: If the acquiring company attempts to enter a new, significantly different business, they might lack the necessary understanding to ensure the acquired company's continued success.

These challenges can result in poor financial performance in the short term, causing the purchasing company's stock price to drop.

Stock Split and Share Issuances

In some scenarios, the purchasing company's stock price may not directly drop but instead, the number of shares issued by the company increases. This can be due to a share swap deal:

Resolution at Board Meeting: The board of the purchasing company may pass a resolution offering its shares to shareholders of the acquired company as part of a swap deal. Reduction in Acquired Company's Shares: The number of shares of the acquired company is reduced, and more shares of the purchasing company are issued. Potential Price Impact: While the share price may fall temporarily due to an increase in the number of freely tradable shares, this effect is usually short-lived as the acquired company's shareholders sell their holding.

Conclusion

Acquisitions can have varying impacts on the stock prices of purchasing companies, and it's crucial to evaluate each situation carefully. Understanding the strategic benefits, potential risks, and unique aspects of each acquisition can help investors and stakeholders make informed decisions.
