History
Bronco Drilling went public in 2005, bought rigs aggressively, survived a failed 2008 buyout, and was acquired by Chesapeake Energy for $11.00 a share in 2011.
2005-2006: Listing and a rig-buying spree
Bronco Drilling set out in 2005 to build a land drilling rig fleet. Its first step was a stock market flotation in August 2005. It sold 5,865,000 shares at $17.00 (5,715,000 of them new shares from Bronco, 150,000 from its controlling stockholder), raising about $90.4 million for the company. It used the money to repay loans, including $13.2 million to Theta Investors, LLC, which had funded the Strata acquisition, and $22.2 million to General Electric Capital Corporation.
Purchases followed quickly. In September 2005 Bronco agreed to buy Thomas Drilling Co.'s assets for $68 million cash, and Eagle Drilling's rigs and equipment for $50 million. The Eagle deal closed on October 3, 2005. A $50.0 million term loan from Merrill Lynch Capital, of which $43.0 million was drawn at once, helped fund the buying. In October 2005 a second share offering of 3,500,000 shares at $23.00 was priced, with about $50.0 million earmarked to repay Thomas-related borrowings. In December Bronco agreed to buy six rigs from Big A Drilling for $16.3 million cash plus shares, closing in January 2006. That month it also signed a revolving credit facility of up to $150 million with Fortis Capital Corp. A third offering in March 2006 priced 3,000,000 shares at $22.75, with Bronco selling 1,700,000 to repay borrowings. Each raising diluted existing holders.
2007-2008: Diversifying and a failed sale
The record is quiet through 2006 after March. In January 2007 Bronco bought Eagle Well Services, Inc. for $2.5 million cash, 1,070,390 shares and assumed debt. It brought 31 workover rigs (used to maintain existing wells) and was described as the first step in diversifying beyond contract drilling. In November 2007 a subsidiary agreed to take a 25% stake in Challenger Limited of the Isle of Man, in exchange for six rigs and $5 million cash.
In January 2008 Bronco agreed to be bought by Allis-Chalmers Energy for about $437.8 million, or $16.33 a share. In June the terms were changed to $200.0 million cash plus 16,846,500 Allis-Chalmers shares, worth $18.25 per Bronco share. In August the deal was called off because Bronco's stockholders were unlikely to approve it. Bronco paid Allis-Chalmers $4.5 million. In September 2008 it replaced its Fortis facility with a new revolver of up to $150 million, maturing in 2013.
2009-2010: Mexico and shrinking
In September 2009 Bronco sold 60% of a new Mexican rig venture, Bronco MX, to Carso Infraestructura y Construccion for US$30.0 million, keeping 40% after contributing six rigs, with three more to follow. It also replaced the Fortis revolver with a $75 million revolver from Banco Inbursa and gave Inbursa a three-year warrant over up to 5,440,770 shares at $6.50 to $7.50. In February 2010 Inbursa waived compliance with the debt-to-EBITDA limit (a test of debt against earnings) through the quarter ended June 30, 2010. The filing did not say why.
In September 2010 Bronco auctioned substantially all of its discontinued well servicing business and six drilling rigs for expected net proceeds of about $20.8 million, and sold two more rigs for about $6.5 million. The money was meant to pay down the Inbursa revolver.
2011: Sale to Chesapeake
On April 15, 2011 Chesapeake Energy, through its subsidiary Nomac Acquisition, agreed to buy Bronco for $11.00 cash per share, about $315 million including debt, working capital and warrants. Third Avenue Management and Inmobiliaria Carso, together holding about 32%, committed to tender their shares. The board unanimously backed the deal, and a $13 million termination fee applied in certain cases.
Shareholder lawsuits followed, growing to ten, alleging the price was too low. In May the Delaware parties agreed in principle to settle: the window in which a termination fee could be owed shortened from 12 to 9 months, extra disclosures were promised and the offer was extended to May 31. The settlement needed court approval, and the final court outcome was not stated. The US antitrust waiting period ended early on May 2.
The tender offer expired June 3 with about 24,959,224 shares tendered, around 86.7% of those outstanding. Chesapeake then used a top-up option to buy 63,550,899 new shares, passing 90%, and completed a short-form merger without a shareholder vote on June 6. Remaining shares became $11.00 cash, except for holders properly exercising appraisal rights. The Inbursa warrant was cashed out for $21,763,080, and the Inbursa credit agreement was repaid and ended. As of June 2011, Bronco was an indirect wholly owned Chesapeake subsidiary, delisted from NASDAQ, and it deregistered with the SEC on June 16, 2011.
