Express Scripts/Medco

Express Scripts, Inc., announced an agreement to buy Medco Health Solutions, Inc., for $29.1 billion on July 21 in a deal that would create the largest pharmacy benefits manager in the United States. The buyer will pay $28 in cash and 0.81 Express Scripts shares for each Medco share, consideration worth about $71.36, which reflects a 28 percent premium to the target’s closing price on the day before the deal was announced.

The major hurdle to the deal’s completion will likely be regulatory scrutiny from the Federal Trade Commission. The merger would leave Express Scripts with only one large independent competitor, CVS Care­mark Corporation, but insurers and large companies could also opt to manage drug prescriptions themselves rather than rely on Express Scripts or CVS. For example, UnitedHealthCare Group currently uses Medco but will bring its pharmacy benefits in-house next year.

Express Scripts and Medco hope to close the transaction in the first half of 2012 pending approvals from the FTC, other regulators, and both sets of shareholders.

BHP Billiton / Petrohawk

BHP Billiton is paying a hefty premium to expand its shale gas production business in the United States with its agreement to buy Petrohawk Energy Corporation for $12.1 billion in cash and another $3 billion in assumed debt. At $38.75 per Petrohawk share, the deal came at a 65 percent premium to the target’s closing price on July 14, the day the deal was announced.

BHP, a mining company whose two corporate entities are listed in London and Melbourne, just entered shale gas in February, when it struck a $4.75 billion deal to buy shale assets in Arkansas from Chesapeake Energy Corporation. BHP and Petrohawk hope to close their transaction in the third quarter of this year pending approvals from Petrohawk shareholders and regulators.

Google / Motorola Mobility

Google Inc. lost out to Apple Inc. and Microsoft Inc. in the bidding for Nortel Networks Corporation’s patents in June. But seven weeks later, Google struck a deal that will give it not only 17,000 patents related to smartphone technology but also the capacity to manufacture the phones. The Internet search giant agreed on August 15 to pay $12.5 billion in cash for Motorola Mobility Holdings, Inc. At $40 per target share, the deal comes at a 64 percent premium to the target’s closing price on August 12, the last trading day before the deal was announced. The price validated the decision of Motorola, Inc., to split into Motorola Mobility and Motorola Solutions, Inc., a division announced in 2008 and completed in January. While Motorola Mobility makes Droid smartphones and the Xoom tablet, Motorola Solutions focuses on communications products and services for businesses and governments. The Droid devices run Google’s Android mobile operating system, which Google also licenses to other device manufacturers. Google says it will run Motorola Mobility as a separate division, though the long-term effect on the device market on other Android licensees is unclear. Google and Motorola Mobility hope to close the deal early next year pending approvals from Motorola shareholders and regulators in the United States and abroad.

HP / Autonomy

Almost a decade ago, Hewlett-Packard Company made a large bet on personal computers with the $25 billion acquisition of Compaq Computer Corp. HP walked away from that bet, but made another large one on August 17, when the tech giant announced that it hoped to sell or spin off its PC division and agreed to buy enterprise software company Autonomy Corporation plc for $10.8 billion in cash.

HP currently derives less than 3 percent of its revenues from software.

HP will pay $42.11 per Autonomy share, a 64 percent premium to the target’s closing price on August 17. HP shareholders panned the deal; the buyer’s shares fell by 22 percent on the news, which amounted to a $14 billion decline in the company’s market capitalization. The companies hope to close the deal by the end of the year pending approvals from regulators and Autonomy shareholders.
