Common Stock Returns around Farmout Announcements in the Oil and Gas Industry

Abstract

We examine market reactions to farmout agreements, a common form of strategic alliance undertaken by oil and gas explorers internationally. Using an Australian sample of 722 farmout agreements announced during the 1990–2016 period, we find that farmout announcements generate a positive cumulative average abnormal return of 3.60% for farmors and 1.90% for farminees over a 3-day event window. Cross-sectional analysis of farmors’ event returns provides results consistent with the resource pooling hypotheses. We also find that farmors’ announcement returns are sensitive to the underlying oil price volatility, consistent with the real options view of farmout arrangements.
