The stock of Denver-CO-based Liberty Oilfield Services Inc. LBRT has lost around 16.4% since its second-quarter earnings announcement on Jul 27. The company’s worse-than-expected top and bottom-line performance and investor scepticism, fuelled by the prevailing industry supply chain challenges and management’s unwillingness to deploy additional capacity, triggered the negative reaction.What Did Liberty Oilfield’s Earnings Unveil?Liberty Oilfield Services reported second-quarter 2021 loss per share of 29 cents, wider than the Zacks Consensus Estimate of a loss of 12 cents. The underperformance reflects higher operating expenses, which soared to $617.3 million from $161.9 million in the second quarter of 2020.However, the bottom line compared favorably with the year-ago quarter’s loss of 55 cents due to strong execution and contribution from the onshore hydraulic fracturing business in the United States and Canada that the company acquired from Schlumberger SLB in January.Total revenues came in at $581.3 million, below the Zacks Consensus Estimate of $595 million, but surged from the year-ago level of $88.4 million.The second-quarter adjusted EBITDA was $36.6 million against the prior-year quarter loss of $8.3 million. Meanwhile, Liberty’s fleet count most likely stayed around the low 30s throughout the quarter. Liberty Oilfield Services Inc.
