What is an acquisition?

An acquisition is where one corporation purchases another company by acquiring some or all of the company’s shares or assets. An acquisition allows the acquiring company to build its capacity, resources and skills by taking control of the acquired company’s strengths.

For example:

The largest acquisition in history: Mannesman & Vodafone Air Touch PLC

eBay acquired Skype in 2005 for $2.6 billion

Microsoft then acquired Skype for $8.5 billion in 2011

Successful Mergers & Acquisitions: Lessons From History

Mergers and acquisitions have occurred as long as companies have existed, providing an opportunity for expansion, entry to new markets and an exit strategy for owners and founders.

These are the biggest mergers and acquisitions examples from around the world since 1900.

1. Reducing competition

Year: 1901

Andrew Carnegie founded Carnegie Steel Company. Elbert H Gary founded Federal Steel Company. In 1900, Charles M Schwab became president of the Carnegie Company and approached Gary with the idea of a massive consolidation. With the help of J.P. Morgan, they brought the United States Steel Corporation, Federal Steel Company and National Steel Company under the Carnegie Company.

Key takeaway: This merger consolidated the steel industry, reducing competition and expanding the Carnegie Company to become the first billion-dollar corporation in American history.

2. Expanding capability into new markets

Year: 1915

Midvale Steel Co acquired Worth Brothers and Remington Arms Co in a $100,000,000 Concern, reportedly making 2,000,000 rifles and issuing $55,000,000 stock for companies combined.

Key takeaway: This merger reduced competition by acquiring Worth Brothers Company and expanded Midvale Steel’s capabilities into the manufacture of firearms.

3. Increasing business capacity and improving customer experience

Year: 1928

The great utilities merger of the 1920s, the purchase of Brooklyn Edison by Consolidated Gas created economies for the distribution of light and power to millions of New Yorkers. The deal also increased Edison Power’s Kilowatt capacity on the railways.

Key takeaway: This merger to consolidate energy companies enabled efficiencies in light and power distribution and increased capacity with the integration of infrastructure. Energy company acquisitions are still relevant today to stay competitive in the market.

4. Exiting a company and consolidating infrastructure

Year: 1930

Purchased out of bankruptcy in 1902, the San Joaquin Light and Power Corporation was acquired by the Great Western Power Company in 1924, and subsequently sold to the Pacific Gas and Electric Company in 1930 in exchange for stock to consolidate utilities in Northern and Central California.

Key takeaway: Energy companies that regularly reinvent through mergers and acquisitions remain relevant to changing customer needs.

5. Facing or avoiding a legal challenge to an acquisition

Year: 1949

In 1949 Pan American Airways acquired American Export Airlines (AOA). On May 17, 1950, the United States Civil Aeronautics Board (CAB) ruled against the merger on the basis that the transfer of certificates to provide airline services in particular regions and certificates to transfer assets were not approved. President Harry S. Truman overturned the decision, and AOA merged into what would become Pan American's Atlantic Division on September 25, 1950.

Year: 1989

In 1988, RJR Nabisco was purchased by Kohlberg Kravis Roberts & Co in what was at the time the largest leveraged buyout in history. In 1999, due to concerns about tobacco lawsuit liabilities, the tobacco business was spun off into a separate company, and RJR Nabisco was renamed Nabisco Holdings Corporation.

Key takeaway: Thorough due diligence can help to ensure that all licences, insurance and legal documentation are in place before an acquisition, allowing the combined companies to focus on integration.

6. Effective stakeholder engagement strategies smooth the merger process

Year: 1969

On January 1, 1969, Atlantic Richfield Company acquired oil/gas exploration company Sinclair Oil in a $3.7 billion deal, which was the largest in the industry's history at the time. Stockholders of both companies approved the merger in special meetings held in New York and Philadelphia.

Year: 1959

Stockholders of both companies approved the merger of Sylvania Electric Products, Inc., into the General Telephone Corporation. The combined companies adopted the name General Telephone and Electronics Corporation.

Key takeaways: Clear and effective communication with stakeholders at the right point in time can ensure all parties are informed to make timely decisions.

7. Expert advice facilitates the first unsolicited cross-border acquisition of a German company

Year: 2000

On February 4, 2000, Vodafone AirTouch PLC acquired Mannesmann AG for more than US $190 billion, in a deal that reshaped the mobile telecom marketplace. At the time, the cross-border transaction was the largest merger in history. Vodafone Airtouch PLC engaged Goldman Sachs, which created the world’s largest telecom provider, as a financial advisor throughout the transaction. It was also unique in being an unsolicited acquisition of a German company, which was unprecedented.

Key takeaway: Seek expert financial advice from an industry leader to confidently execute complex acquisitions.

8. Changing technology outpaces an acquisition strategy

Year: 2000

America Online Inc. (AOL) acquired Time Warner Inc. for some $182 billion in stock and debt. The result was a $350 billion mega-corporation, AOL Time Warner. However, within a few months, a recession hit, the dot-com bubble burst, and the AOL-Time Warner deal was dubbed “the worst merger in history.”

Key takeaway: Sometimes even the experts don’t predict the pace of new technology adoption, resulting in an investment that doesn’t pay off.

9. Access to new markets means meeting regulatory requirements in each jurisdiction

Year: 2015

In a long-awaited deal and reportedly the third-largest acquisition in history (largest ever in Britain), AB InBev acquired SABMiller. Combining two of the world’s leading beer companies, the merged company Newbelco divested key brands to comply with anti-trust law.

Key takeaway: Following complex merger negotiations and court settlements, once combined the new company divested key brands to meet regulator concerns about maintaining fair competition.

10. Divestiture may be required before a merger

In a deal that closed on 28 February 2022 following 2 years of negotiation, S&P Global purchased IHS Markit in a definitive all-stock deal for around $44 billion. Before the transaction could be completed, IHS Markit sold Base Chemicals to NewsCorp to alleviate concerns about fair competition.

Key takeaway: Divestiture may be required before a merger is allowed to ensure compliance with merger laws. Engaging with the regulators during the merger is key to meeting all legal requirements in each market.

11. An acquisition can ensure relevance and enable advances in technology

Year: 2023

Broadcom (the continuing company from the 2016 Avago Technologies and Broadcom merger) acquired VMWare for $69 billion in a cash and stock transaction. Continuing as VMWare, Broadcom expands its offering with enterprise software focusing on multi-cloud services for apps and virtualisation technology, building on its existing semiconductor and connectivity chip capabilities to address complex technological requirements.

Key takeaway: A smart acquisition of complementary technology can power up a company to advance its services and meet ever-changing customer demands in competitive markets.

Top 3 powerful mergers and acquisitions and why they were successful

Preserving a healthy company culture: Disney, Pixar & Marvel

Mass media conglomerate Disney found enormous success with two very famous acquisitions; first, of animation heavyweight Pixar, then Marvel Entertainment.

Walt Disney Co. acquired Pixar in 2006 for $7.4 billion and has since seen tremendous success with films like WALL-E, Finding Dory and Toy Story 3 – each of which has generated billions of dollars in revenue for the company.

One of the main reasons for the success of this acquisition was the access it gave Disney to Pixar’s advanced animation technology. By keeping Pixar’s culture distinct, Disney was able to generate significant value without destroying what made Pixar unique or successful.

Shortly after, Disney acquired Marvel Entertainment, paying $4 billion for the entertainment company in 2009. With a highly lucrative string of Marvel films premiering at the box office since then, they have already made their money back – with more to come, no doubt.

Seeing potential in unknown software

In 2005, Google purchased the relatively unknown Android, a mobile startup that had been founded only a few years prior. While the exact sum is undisclosed, it’s estimated that the deal was worth approximately $50 million - a fraction of the $130 million Google spent on acquisitions that year. Google spent $1.65 billion purchasing YouTube just over a year later.

Android gave Google the mobile operating system (OS) it needed to compete with the likes of Apple and Microsoft in the growing mobile market and expand its reach far beyond desktops.

Android has easily been Google’s most successful acquisition; when it comes to smartphones, their estimated market share is a whopping 85% (IDC).

Be inspired: Smaller M&A deals create more long-term value

Horizontal mergers benefit investors with a better return on capital.

Exxon Corp. and Mobil Corp. - the first and second largest oil producers in the United States announced their merger in 1998, closing the deal in just 282 days. The megadeal closed at $80 billion, with investors quite literally quadrupling their money in the process. Both brands continued to exist, with no noticeable change for motorists.

Successful mergers and acquisitions with Ansarada

With an unparalleled understanding of the requirements of modern deals, Ansarada provides software that keeps everything in one secure location, allowing you to concentrate on the finer details of the merger or acquisition process. Here are just two examples out of the many deals we’ve helped to facilitate:

1. PBL Media Ltd

In 2006, an Ansarada Data Room was used to facilitate the $5 billion recapitalisation of James Packer’s company, PBL Media Limited. The deal saw the media giant sell half of its media assets, including the Nine television network, to private equity investors. The move allowed the company to ‘bankroll its ambitions in gaming and capitalise on the federal government’s changes to media ownership laws’ (Australian Financial Review).

2. Westpac and St. George

In early 2008, Westpac and St. George banks outlined their intention to merge, and the deal was approved by shareholders and the Australian Federal Court in November of the same year. The combined entity was valued at over $66 billion in the megamerger executed in Ansarada’s Virtual Data Room.
