According to the Complaint, the Company made false and misleading
statements to the market. Alta Mesa and Kingfisher were touted as
“superior quality” and “[w]orld [c]lass” assets compared to other oil &
gas companies. In fact, the Company faced serious operational setbacks.
Other major oil companies had moved assets away from the region that
Alta Mesa operates in. The Company made a series of corrective
disclosures, with the final disclosure occurring on February 25, 2019,
when the Company announced a delay in the release of its 2018 financial
results. Over the course of these corrective disclosures, Alta Mesa
stock lost 95% of its value. When the market learned the truth about
Alta Mesa, investors suffered damages.
