History
A dormant biotech shell became an Appalachian gas producer in 2011, expanded through partner-funded ventures and debt, then sold its core business in 2020 and went private.
2006-2010: A shell with one asset
The company began this story as The St. Lawrence Seaway Corporation, a shell whose only asset was a stake in a drug-development venture, T3 Therapeutics. In June 2006 it withdrew its audited accounts for the year to March 2005 after finding it had wrongly accounted for its share of T3's research spending. The restated loss per share widened from 18 cents to 27 cents.
Control changed in 2007. Under a deal with merchant bank Bernard Zimmerman & Company, Zimmerman became chairman and chief executive. The deal closed on 31 August 2007, and the company reincorporated in Delaware. Zimmerman ended up with 14.5% of the shares. In January 2010 the company sold its T3 stake back to the venture for $100,000, which left an empty listed shell.
2011-2015: Nytis and the gas business
In early 2011 the shell agreed to merge with Nytis Exploration (USA) Inc. of Denver, a gas producer. The merger closed on 14 February 2011. Nytis holders received 47,000,003 new shares, about 99% of the company, and no cash was used. Yorktown Energy Partners' funds V and VI held a combined 75.5%, and Cadent Energy Partners' RBCP fund held 17.2%. Patrick McDonald became chairman and chief executive, and Kevin Struzeski chief financial officer. The business had interests in about 433 gross (176 net) producing wells and about 349,000 gross acres in the Illinois and Appalachian Basins.
The new company's ambitions soon ran ahead of its funding. A $29.6 million purchase of gas properties in eastern Kentucky and West Virginia from The Interstate Natural Gas Company, agreed the day the merger closed, had to be split into two closings because financing was not ready. In mid-2011 Carbon raised $30 million: 44.4 million shares at $0.45, plus $10 million of Series A preferred bought by Yorktown Energy Partners IX. That completed the purchase on 29 June, after $765,000 net in extension payments because the financing took longer than expected. The company renamed itself Carbon Natural Gas Company.
After that, Carbon chose to sell down interests rather than borrow. In September 2012 Liberty Energy paid $3.66 million for a 40% working interest in Kentucky leases and agreed to carry part of the drilling cost. In June 2014 Carbon paid Cadent's RBCP fund $0.40 a share for all 8,153,777 of its shares, about $3.3 million, and cancelled them. In October 2014 Nytis and Liberty agreed to sell the rights below the base of the Clinton Formation to an unnamed buyer, with Nytis's share of the cash about $12 million. A preliminary closing followed in December, with title defects to be cured within 75 days.
2016-2018: Ventures and a big buyout
The share count shown for the end of 2015 (about 5.4 million) is far below the end-2014 figure (about 107 million). The sources do not explain the difference, and the one-for-twenty consolidation that took effect on 15 March 2017 postdates it, so the figures should be treated with caution.
In October 2016 Carbon bought 2,334 producing Appalachian gas wells and more than 900 miles of gathering line from EXCO Resources and the BG Production companies for just $9 million. It refinanced into a new four-year, $100 million revolver from LegacyTexas Bank.
In 2017 it began growing through ventures funded by outside investors. Carbon California Company, formed in February, had $22 million of equity and up to $35 million of notes, and bought Ventura Basin assets. Carbon took 17.8% and the manager's role for no cash. In April came Carbon Appalachian Company, with $100 million of commitments. Carbon put in $2 million for 2%, and could earn up to a further 20% once the outside investors cleared their return hurdle. In August the Appalachian venture bought $21.5 million of West Virginia gas properties, and Carbon raised its commitment to $23.6 million, or 26.5%.
In April 2018 Yorktown Energy Partners XI put $5 million into new convertible preferred stock. A warrant exercise had lifted Carbon's stake in the California venture to 54%, so its $43 million Ventura Basin purchase from Seneca Resources, completed in May, was consolidated onto Carbon's own books. Carbon then agreed to buy out Old Ironsides Energy's 73.5% of the Appalachian venture. It closed on 31 December 2018, for $33 million in cash plus about $25 million of Carbon's own 10% five-year notes. The credit facility was rewritten into a $500 million-limit revolver plus a $15 million term loan.
2019-2020: Debt, sale and going private
The debt soon bit. In August 2019, eight months after the buyout, the lenders gave limited waivers for loan breaches. They required $3 million of liquidity, no bills running past 90 days, and sales of non-core assets. A second round in February 2020 cut the borrowing base from $75 million to $73 million, with further cuts scheduled through May.
On 7 April 2020 Carbon agreed to sell its entire Appalachian and Illinois Basin business to Diversified Gas & Oil for $110 million plus up to $15 million contingent. Yorktown's funds approved it by written consent, so no shareholder vote was needed. The sale closed on 26 May at a base cash price of $99.2 million. Carbon repaid and cancelled its bank facility and scheduled repayment of the $25.1 million of Old Ironsides notes. Mark Pierce and Kevin Struzeski left, staying on as consultants at $25,000 a month. In July the remaining California business needed its own waivers from its Prudential lenders.
On 16 July 2020 Carbon opened a going-private process through a reverse stock split. Shareholders approved a 4-for-1 reverse split on 22 October, and the charter amendment was filed in Delaware on 26 October. The company deregistered its securities on 27 October, ending its SEC reporting. As of 6 November 2020, the split awaited notice of its effective date from FINRA, and the filings do not state what, if anything, holders were paid. Whether the $15 million contingent payment was ever earned is also not known from the record.
