10. Liberty Energy Inc. (NYSE:LBRT)
Liberty Energy grew its share prices by 24.49 percent week-on-week to hit a new all-time high, as investors gobbled up its shares after a strong earnings performance and an upbeat outlook amid ongoing supply disruptions.
On Friday alone, the stock soared to its highest price of $33.15 before trimming gains to finish the session just up by 1.30 percent at $32.74 apiece.
In an earnings call earlier in the week, Liberty Energy Inc. (NYSE:LBRT) said that it was able to grow its net income for the first three months by 12 percent to $22.5 million from $20.1 million in the same period last year. Revenues broke past the $1 billion level, finishing at $1.02 billion or 4 percent higher than the $977 million year-on-year.
CEO Ron Gusek pointed to the “unprecedented oil and gas supply disruptions” as among the factors that buoyed its growth, with lingering supply challenges expected to continue benefiting Liberty Energy Inc. (NYSE:LBRT) and its counterparts in North America.
“Over time, this dynamic may support structural tailwinds for North America, as global consumers reevaluate energy supply chains and diversify sourcing, with greater reliance on US and Canadian-sourced oil and refined product supply,” the energy firm said.
“As the markets weigh rising concerns over physical oil and gas supply shortages against potential ceasefire implications, North American [exploration and production] companies are evaluating a range of macroeconomic scenarios. The recent rise in oil prices is well above early-year expectations, now driving substantially better E&P economics with greater potential for increased free cash flow generation,” it added.
