better than Q4 with sequential revenue increases. With what we know today, we anticipate revenue and earnings to improve each quarter throughout 2022. We remain differentiated by our service line diversity, forward-leaning technology, geographic diversity, and balanced commodity exposure. The shift of our top-line revenue derivation towards completion tools and technology over the last several years has significantly reduced the capital and labor needs of the Company to generate earnings growth. We have proven our ability to grow earnings while emerging from a downturn and believe our asset-light business model will enable us to capitalize on an improving market environment.”
