AMSTERDAM, July 28, 2021 /PRNewswire/ -- Core Laboratories N.V. (NYSE: "CLB US" and Euronext Amsterdam: "CLB NA") ("Core", "Core Lab", or the "Company") reported second quarter 2021 revenue of $118,700,000. Core's operating income was $12,800,000, with earnings per diluted share ("EPS") of $0.17, all in accordance with U.S. generally accepted accounting principles ("GAAP"). Operating income, ex-items, a non-GAAP financial measure, was $13,200,000, yielding operating margins of 11% and EPS, ex-items, of $0.18. Year-over-year and sequential financial improvements are attributed to a continuation of U.S. onshore activity growth and market penetration, along with an improving landscape for Core's international operations. A full reconciliation of non-GAAP financial measures and year-over-year comparisons are included in the attached financial tables.

Core's CEO, Larry Bruno stated, "During the second quarter of 2021, the Company saw increased revenue, increased EBITDA, increased free cash flow and increased EPS. At the same time, Core continued to execute on its strategic financial objectives by reducing net debt and improving its leverage ratio compared to the first quarter. Core's revenue growth improved sequentially, outpacing the rig count in both North America and internationally. Reservoir Description, having greater international exposure, did face some continuing pandemic-related headwinds during the quarter. Core's Production Enhancement segment exceeded sequential top and bottom-line expectations, with U.S. energetic sales nicely outpacing the growth in completions. Core remains optimistic regarding the remainder of 2021, as activity in North America progresses and international activity builds momentum."

Reservoir Description

Reservoir Description operations are heavily exposed to international and offshore activity levels, with approximately 80% of its revenue sourced from outside the U.S., where reservoir rock, reservoir fluid and derived product samples originate from international projects. Reservoir Description revenue in the second quarter of 2021 was $78,300,000, up 2.3% sequentially. Operating income for the second quarter of 2021 on a GAAP basis was $7,300,000, while operating income, ex-items, was $7,500,000, down 26.5% sequentially, yielding operating margins, ex-items, of 9.6%. While Reservoir Description revenue increased sequentially, the segment's performance fell below the Company's second quarter 2021 projections. Operating income and operating margins for the quarter were negatively impacted as the Company is in the process of restoring temporary cost reduction measures previously put in place. The segment continued to face project delays related to the pandemic; client activity and project advancement in many international markets, including parts of Europe, South America, the Middle East and Asia-Pacific regions were impacted by government-enacted policies to mitigate COVID-19 transmission.

During the second quarter of 2021, Core Lab, under the direction of Reconnaissance Energy Africa Ltd ("ReconAfrica"), was engaged to provide laboratory analyses on conventional cores from exploratory wells in the Kavango Basin, Northeastern Namibia. The laboratory program for this project is leveraging a number of proprietary and patented technologies, such as Core Lab's Reservoir Applied Petrophysical Integrated Data Zoom (RAPIDZoom™) services to assess rock properties and identify prospective reservoir targets over a thick interval of predominantly marine strata. RAPIDZoom™ allows the scientists involved in the project to collaboratively examine the core samples at high resolution, revealing details on lithology, texture and stratigraphic relationships, all while working from remote locations. The analytical program on these Kavango Basin cores also includes Core's proprietary, native-state electrical properties laboratory testing, which allows for both improved calibration of downhole electric logs and expedited oil-in-place assessments. Core Lab is very pleased to be assisting the technical experts at ReconAfrica in their evaluation of potential reservoirs in this expansive, onshore sedimentary basin.

Client adoption of Core's proprietary digital innovations that leverage the Company's unparalleled database of global reservoirs also expanded during the second quarter of 2021. Under the direction of Carnarvon Petroleum Limited in Australia, Core Lab employed its Advanced Rock Typing (ART™) technology, one of Core's latest and most advanced digital and artificial intelligence ("AI") offerings. The robust AI-based model provided Carnarvon with analog petrophysical and engineering parameters on drill cuttings samples from the WA-521-P exploration well on the Northwest Shelf of Australia. Drill cuttings are millimeter-scale, irregularly-shaped fragments of rock produced by the cutting action of the drill bit. Drill cuttings are not suitable for many of the traditional laboratory measurements that require larger, more uniformly-shaped samples. In the absence of conventional core samples, Core Lab used AI technologies to predict important reservoir properties from the drill cuttings, until such time that conventional core can be obtained for traditional laboratory testing protocols. The advanced insights into reservoir quality provided by ART™ were utilized by Carnarvon Petroleum Limited to de-risk geological uncertainties in their offshore Labyrinth project. At the forefront of digitization innovations for more than two decades, Core continues to develop and introduce transformative digital technologies, such as ART™, which leverage Core's proprietary databases. Core is pleased to be assisting Carnarvon in their reservoir evaluation program.

Production Enhancement

Production Enhancement operations, which are focused on complex completions in unconventional, tight-oil reservoirs in the U.S., as well as conventional offshore projects across the globe, posted second quarter 2021 revenue of $40,500,000, up 27% sequentially, exceeding the Company's second quarter 2021 projections. Core's proprietary energetic product sales and diagnostic services, in both U.S. and international markets, experienced growth and market penetration. Operating income on a GAAP basis was $3,800,000, while operating income, ex-items, was $3,900,000, up 114.3% sequentially. Operating margins were 9.5% for the second quarter of 2021, expanding 380 bps sequentially.

During the second quarter of 2021, Core Lab saw growing market acceptance of its innovative, proprietary Pulse Wave™ Tubular Conveyed System. Pulse Wave™ uses a unique energy transfer technology to trigger multiple, unevenly-spaced perforating guns in a single downhole trip. Traditionally, operators place a series of inert guns between live guns to create a continuous communicating string. This is a time-intensive process, requiring multiple down hole trips. These types of configurations can lead to extended rig times and may have low reliability. In the second quarter of 2021, a client expressed a need to complete a horizonal well, with predetermined, unevenly-spaced stages, with an aim to optimize injection efficiencies. Utilizing the Pulse Wave™ system, perforating guns were loaded with up to 20 perforating charges per gun, with intervals varying from 125 to 284 feet between each live gun. By using Pulse Wave™ to sequentially trigger the live guns, the system eliminated the need for hard-wired, gun-to-gun connections, and thus multiple potential failure points. The perforation operation was performed as planned and resulted in the client saving over 30% on the cost of consumables, in addition to reduced rig time. The client was very satisfied with the high reliability and effectiveness of the Pulse Wave™ System; they are making plans to expand the use of Pulse Wave™ for future injection wells, and potentially for re-perforating existing producing wells. Pulse Wave™ is just one of many Core Lab technologies that were developed by its internal team of energetic product experts. Core's internal pipeline of new technology offerings is a cornerstone of the Company's success and a credit to Core's dedicated, innovative staff.

Also, during the second quarter of 2021, Core's completion diagnostic services were on display. Core's PackScan^® technology was used in an offshore South Atlantic margin development project to assess the effectiveness of an open-hole, horizontal gravel pack. In offshore environments, operators often complete wells using a gravel pack. The goal is to gravel pack the screen annular space in order to stabilize the formation and control the entry of formation fines during production. The traditional method for assessing the competence of gravel packs is a standard density log to identify annular voids or formation intrusion. To better assess the quality of the gravel pack, Core deployed its proprietary, high-resolution PackScan^® tool to identify even minor gravel pack anomalies. The interpreted PackScan^®log enabled the operator to make critical decisions as to whether to bring the well on aggressively, so as to accelerate production, or slowly, so as to prevent a screen failure. Core's PackScan^® log identified a void in the annular pack that would have led to screen erosion and ultimately a failure of the completion. After reviewing the PackScan^® log, Core's diagnostic engineers recommended the operator bring the well onto production at a lower rate, to enable the annular void to be filled in from the ample reserve gravel that was emplaced above the producing interval. Based on Core's recommendation, by using this data-driven approach, the client decided to bring the well's production at a reduced rate, minimizing the risk of a very expensive completion failure.

Free Cash Flow and Dividend

Core continues to focus on generating free cash flow ("FCF"), a non-GAAP financial measure defined as cash from operations less capital expenditures. For the second quarter of 2021, cash from operations was $9,500,000 and capital expenditures were $2,900,000, yielding FCF of $6,600,000, marking another quarter in the Company's long history of generating positive FCF.

For the second quarter of 2021, after funding the quarterly dividend, free cash was accumulated on the balance sheet, reducing net debt by $5,800,000 or 3.2%, and bringing Core's leverage ratio down to 2.18 as of 30 June 2021. Core will use excess free cash towards retiring some of its long-term debt which is maturing 30 September 2021 and continue its strategy of reducing the Company's leverage ratio.

On 21 April 2021, Core's Board of Supervisory Directors ("Board") announced a quarterly cash dividend of $0.01 per share of common stock, which was paid on 18 May 2021 to shareholders of record on 3 May 2021. Dutch withholding tax was deducted from the dividend at a rate of 15%.

On 28 July 2021, the Board approved a cash dividend of $0.01 per share of common stock payable in the third quarter of 2021. The third quarter dividend will be payable on 24 August 2021, to shareholders of record on 9 August 2021. Dutch withholding tax will be deducted from the dividend at a rate of 15%.

Return On Invested Capital

The Board and the Company's Executive Management continue to focus on strategies that maximize return on invested capital ("ROIC") and FCF, factors that have high correlation to total shareholder return. Core's commitment to an asset-light business model and disciplined capital stewardship promote capital efficiency and are designed to produce more predictable and superior long-term ROIC.

Global events in 2020 created adverse effects which triggered significant asset impairments for goodwill, intangible assets, inventory and other fixed assets, which further distort underlying financial performance and performance metrics, such as ROIC. The Board has established an internal performance metric of demonstrating superior ROIC performance relative to the oilfield service companies listed as Core's Comp Group by Bloomberg, as the Company continues to believe superior ROIC will result in higher total return to shareholders. As of 30 June 2021, Core Lab's ROIC was 9.9% as calculated using the Bloomberg formula and is expected to continue to improve in future periods.

Industry and Core Lab Outlook and Guidance

For the remainder of 2021, Core will continue to execute its strategic plan with a focus on generating FCF and reducing net debt, while maximizing ROIC. Additionally, as part of Core's 2021 strategic focus, the Company will continue to invest in targeted, client-driven technologies that aim to both solve problems and capitalize on Core's growth opportunities. The Company remains well-positioned to meet the needs of its clients, with ample liquidity to invest in its global capabilities. These capabilities include Core's expanding proprietary databases, along with innovations in AI and machine learning, which are the foundation of Core's transformative digital technologies.

With the rapid onset of COVID-19 variants and continued market disruptions, the pace of economic reopening has slowed; however, Core remains optimistic about its growth opportunities throughout the remainder of 2021, as the momentum for international crude-oil markets continues to build and U.S. activity continues to moderately progress. Strong crude-oil commodity prices, the lack of investment in international and offshore crude-oil developments, and increasing crude-oil demand continue to support a recovery of the energy industry over the mid to long term. These crude-oil market circumstances are resulting in an increase in the international rig count and heavy oilfield equipment coming under contract, which are leading indicators of a growing international cycle. With Core Lab having more than 70% of its revenue exposed to international activity, the Company remains active on international projects. As additional field development projects emerge, wells need to be drilled and reservoir rock and fluid sampled before Reservoir Description realizes a revenue opportunity. Expansion of the international market provides growth opportunities for the Company into the second half of 2021 and beyond, with a particular focus on the South Atlantic Margin, Mexico, and the Middle East.

Considering the improvement in international activity and with U.S. land activity projected to grow modestly from second quarter 2021 levels, Core projects third quarter revenue to range from $122,000,000 to $126,000,000 and operating income of $14,000,000 to $15,000,000, yielding operating margins of approximately 12% with incremental margins, ex-items, of 20% to 25%. As stated during the second quarter outlook in April 2021, as employee costs are reinstated into the Company's cost structure, incremental margins will be temporarily impacted. Once these costs are fully restored, Core expects its historical incremental margin performance or better. EPS for the third quarter of 2021 is expected to modestly improve to approximately $0.19 to $0.21.

In summary, Core Lab sees activity levels and financial performance improving throughout the remainder of 2021. Core's growth opportunities are directly related to existing long-term projects returning to normal workflows, as well as expanding client activity and new market penetration, particularly internationally.

The Company's third quarter 2021 guidance is based on projections for underlying operations and excludes gains and losses in foreign exchange. Third quarter 2021 guidance also assumes an effective tax rate of 20%.

Return on Invested Capital

Return on Invested Capital ("ROIC") is presented based on our belief that this non-GAAP measure is useful information to investors and management when comparing our profitability and the efficiency with which we have employed capital over time relative to other companies. ROIC is not a measure of financial performance under GAAP and should not be considered as an alternative to net income.

ROIC is defined by Bloomberg as Net Operating Profit (Loss) ("NOP") less Cash Operating Tax ("COT") divided by Total Invested Capital ("TIC"), where NOP is defined as GAAP net income before minority interest plus the sum of income tax expense, interest expense, and pension expense less pension service cost and COT is defined as income tax expense plus the sum of the change in net deferred taxes, and the tax effect on interest expense and TIC is defined as GAAP stockholder's equity plus the sum of net long-term debt, lease liabilities, allowance for doubtful accounts, net balance of deferred taxes, and income tax payable.

The Board has established an internal performance metric of demonstrating superior ROIC performance relative to the oilfield service companies listed as Core's Comp Group by Bloomberg. As of 30 June 2021, Core's calculation of ROIC using Bloomberg's formula, as described above, was 9.9%.

Free Cash Flow

Core uses the non-GAAP measure of free cash flow to evaluate its cash flows and results of operations. Free cash flow is an important measurement because it represents the cash from operations, in excess of capital expenditures, available to operate the business and fund non-discretionary obligations. Free cash flow is not a measure of operating performance under GAAP, and should not be considered in isolation nor construed as an alternative consideration to operating income, net income, earnings per share, or cash flows from operating, investing, or financing activities, each as determined in accordance with GAAP. Free cash flow should not be considered a measure of liquidity. Moreover, since free cash flow is not a measure determined in accordance with GAAP and thus is susceptible to varying interpretations and calculations, free cash flow as presented may not be comparable to similarly titled measures presented by other companies.
