Altor divests its shares in TGS-NOPEC Geophysical Company ASA


Nov 27 2019

Altor Fund IV (“Altor”) has, following the close of trading at the Oslo Stock Exchange yesterday, divested its entire shareholding in TGS-NOPEC Geophysical Company ASA (“TGS”) through an accelerated book building process.

The transaction marks the exit of Altor’s contrarian investment in Spectrum ASA (“Spectrum”) at year-end 2014 based on the investment thesis that the company could accelerate its strategic agenda during the downcycle in the oil service sector.

Altor has worked actively with Spectrum through the cycle on several strategic and operational initiatives. “Spectrum has invested aggressively through the cycle at record low data acquisition costs, which has positioned the company to capitalize on the counter-cyclical investments in the years to come. Further on, Spectrum has over the last years established a strong strategic position in the South Atlantic, which uniquely positioned the company for a strategic merger with TGS” says Pål Stampe, Partner at Altor and former Chairman of the Board at Spectrum.

The transaction was announced over the Oslo Stock Exchange on November 27th 2019
