Apco Reports Second-Quarter Results

Apco Oil and Gas International Inc. (NASDAQ:APAGF) today announced that for the three and six-month periods ended June 30, 2013, it generated unaudited net income attributable to Apco of $13.5 million and $23.5 million, or $0.46 and $0.80 per share, compared with net income of $12.7 million and $22.8 million, or $0.43 and $0.77 per share for the same periods in 2012.

Net income for the quarter and year-to-date periods was higher than the same periods in 2012 as the benefits of higher operating revenues were partially offset by the combination of greater costs and operating expenses, lower equity income from Argentine investment, and higher income tax expense.

Total operating revenues increased by $8.8 million and $14.0 million during the second quarter and first six months of 2013 compared with the same periods in 2012. Sales revenues from Apco’s Colombian operations and benefits realized from the Oil Plus hydrocarbon subsidy program in Argentina were the primary drivers of higher operating revenues experienced in 2013.

Total sales volumes applicable to Apco’s consolidated interest on a barrel of oil equivalent (BOE) basis were 4 percent higher than second-quarter 2012 and 2 percent higher than the first six months of 2012.

Total costs and operating expenses for the quarter and the six months increased by $6.6 million and $8.9 million, respectively, primarily the result of higher production and lifting costs, depreciation expense, selling and administrative expense, and higher foreign exchange losses. The year-to-date period also benefited from lower exploration expense compared with 2012.

The second quarters of 2013 and 2012 benefited from one-time credits to other income attributable to farm-outs of part of the company’s working interests in properties in Colombia and Argentina.

Apco also experienced lower equity income from its 40.72 percent interest in Petrolera Entre Lomas S.A. (Petrolera). During the second quarter and first six months of 2013, the impact of lower operating revenues and higher operating costs contributed to a decrease of $1.4 million and $4.3 million in equity income from Argentine investment compared with the comparable periods in 2012.

2013 Capital Program and Operational Update

During the first six months of 2013, capital expenditures of $27.6 million attributable to Apco’s consolidated interests were invested primarily in development and exploration drilling in Neuquén basin properties and exploration drilling in Colombia.

Apco participated in the drilling of 13 development wells and two exploration wells in the Neuquén basin in the first six months of the year. An additional four wells were in various stages of drilling and completion at the end of the second quarter.

In Colombia, Apco participated in the drilling of two wells in the Llanos 32 block. The Bandola-1 well was put on production in April and had a favorable impact on revenues in the second quarter. The second well was determined to be unproductive.

Additional activities in the first six months included the acquisition of 3D seismic information in the Coirón Amargo block in Argentina and the Llanos 32 block in Colombia.

In July of 2013, Apco received the remaining governmental approval of its agreements with the province of Tierra del Fuego to extend the term of the company’s three concessions by the ten years provided for by Argentine hydrocarbon law. The ten-year extensions for all three concessions run through August 17, 2026.

Under the extensions, Apco and its partners agreed to pay a total bonus of $5 million and spend $49 million for future exploitation and exploration. In addition, the provincial production tax increases from the current level of 12 percent to 15 percent and could increase up to a maximum of 17.5 percent depending on future increases in product price realizations.

“We are pleased to announce approval of our extension agreements for our properties in the province of Tierra del Fuego,” said Michael Kyle, Apco’s president and chief operating officer.

“The extension agreements extend the reserve life of our properties and allow for a continued stream of investments while supporting future employment for local residents. Negotiations for the extension of the portion of the Entre Lomas concession in the province of Río Negro are advancing and we hope to have an approved agreement this year,” Kyle added.
