AMSTERDAM (2 February 2022) - Core Laboratories N.V. (NYSE: "CLB US" and Euronext Amsterdam: "CLB NA") ("Core", "Core Lab", or the "Company") reported fourth quarter 2021 revenue of $125,100,000. Core’s operating income was $14,200,000, yielding operating margins of 11%, with earnings per diluted share (“EPS”) of $0.06, all in accordance with U.S. generally accepted accounting principles ("GAAP"). EPS, ex-items, a non-GAAP financial measure, was $0.20. Income tax expense in the fourth quarter of 2021 was elevated primarily due to significant fluctuations in foreign currency exchange rates. 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, “The fourth quarter of 2021 reflected the improvement in business landscape for Core Lab, led by year-over-year international revenue growth of over 14%. The Company recorded its highest revenue and EPS since the first quarter of 2020. At the same time, Core further strengthened its balance sheet, with the Company’s leverage ratio improving to the lowest level in seven quarters and approaching pre-pandemic levels. For 2022, we expect to see continued improvement in global market dynamics, particularly for Reservoir Description which takes longer to respond to inflections in market conditions compared to our Production Enhancement segment. Over the course of 2021, Core continued to roll out new products and services in key strategic geographic regions, positioning the Company for improving opportunities in both the U.S. and international markets. However, we anticipate typical seasonal declines in activity as we start the new year, and there are still short-term pandemic-related headwinds, as the sharp increase in virus cases in late 2021 has continued into early 2022. This has impacted operations through a combination of government-imposed lockdowns, delays in client projects and overtime costs to cover quarantine requirements among Core Lab staff. Fortunately, the

recent COVID-19 illnesses experienced by our staff have largely been mild and of short duration, and we anticipate fewer COVID-related impacts as the year unfolds.”

Reservoir Description

Reservoir Description operations are closely correlated with trends in international and offshore activity levels, with approximately 80% of revenue sourced from outside the U.S. Reservoir Description revenue in the fourth quarter of 2021 was $80,100,000, up 2% sequentially. Operating income for the fourth quarter of 2021 on a GAAP basis was $7,200,000, while operating income, ex-items, was $7,100,000, down 17% sequentially, yielding operating margins, ex-items, of 9%. Cost of operations in the fourth quarter of 2021 increased due to restoration of employee salary costs and continued operational inefficiencies associated with the global pandemic.

During the fourth quarter of 2021, Core began the initial work on a large, long-planned, reservoir evaluation project in the Middle East. This significant project had been delayed by local government-imposed shutdowns related to the COVID-19 pandemic. In 2019 and early 2020, Core Lab invested to expand analytical capabilities in the host country to service this extensive coring program and other emerging opportunities. The analytical program on this multi-well, conventional reservoir project will employ the full range of basic and advanced rock properties capabilities, including Core Lab proprietary methods and technologies. Work on this project will grow over the next few quarters and continue throughout 2022 and into 2023.

Also, during the fourth quarter of 2021, demand for subsurface evaluation services to support the oil and gas industry’s energy transition and decarbonization efforts continued to grow. As the quarter unfolded, Core Lab launched several client-directed laboratory analytical projects relating to Carbon Capture and Storage (“CCS”). Coordination and planning efforts are underway with a number of U.S. and international companies on projects aimed at evaluating potential sites for CO2 sequestration. Core Lab’s role in these projects is to evaluate the geologic, petrophysical and engineering aspects of the rocks and formation fluids, all critical inputs into modeling and identifying the subsurface risks unique to each potential sequestration site. During the quarter, Core Lab initiated a core evaluation program for an applied technology company on 180 feet of conventional core and associated sidewall cores from a potential sequestration site in Illinois, U.S. Core’s initial laboratory analytical program is needed to assess the reservoir and seal rock properties, and will also be used to form the foundation for determining the storage capacity of the stratigraphic target. As the project progresses, Core will utilize its advanced rock and fluid analytical technologies to refine the client's understanding of this carbon sequestration opportunity and how to optimize CO2 injection methodologies.

Another emerging opportunity associated with energy transition involves leveraging Core’s proprietary, legacy portfolio of geological studies and fluid property datasets on conventional reservoirs and seal rock. Datasets, accessible through Core’s proprietary database platform, RAPIDTM, are proving invaluable to operators evaluating potential CCS sites in onshore and offshore Miocene and Oligocene reservoirs along the U.S. Gulf Coast. These legacy studies, originally conducted to evaluate hydrocarbon reservoirs, provide critical data for reconnaissance, benchmarking, and risk reduction ahead of new coring projects for CCS site assessment.

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 fourth quarter 2021 revenue of $45,000,000, up 15% sequentially. While sequential financial performance was strong, growth opportunities were somewhat constrained during the quarter due to longer lead times in the supply chain and short supply of certain raw materials. Operating income on a GAAP basis was $7,000,000, while operating income, ex-items, was $7,100,000, up 43% sequentially. The improvement of fourth quarter 2021 operating margins to 16%, expanding 310 basis points sequentially, was underpinned by gains in manufacturing efficiencies, strong international sales, and continued market penetration of the Company's pre-assembled GoGun® and Oriented GoGun®.

During the fourth quarter of 2021, Core Lab was approached by an operator conducting business in the Austin Chalk and Eagle Ford Formations to provide expertise when performing completions in smart wells. Smart wells, also referred to as “intelligent wells”, utilize fiber optic cables attached to the outer wall of the casing, along with downhole sensors and valves which are run and cemented in place during the well completion. These sensors relay real time data through the fiber optic cable to the surface, allowing the operator to optimize production rates and make critical decisions on fracking, well spacing, and artificial lift programs. Following installation of the fiber optics, the well must still be perforated to create communication between the wellbore and the formation. These perforations are required for both frac stimulation and subsequent production. Precise alignment of the perforating system is critical to ensure that the fiber optic cables are not cut when the energetics are triggered. Cutting the cables would lead to a loss of communication with the down-hole sensors and valves. The operator selected Core's proprietary Zero180™ Oriented Perforating System with Core’s HERO® PerFRAC charges for these smart wells. This perforating system and energetic design provides the most accurate oriented system available in the industry, yielding an advantage over competitive products whenever smart wells are being constructed. Core’s expertise supported the completion of over 50 stages without damage to the downhole smart well components.

Core continues to innovate solutions for evaluating well completions and reducing well costs. During the fourth quarter of 2021, Core's completion diagnostic services were called upon by multiple operators in the deepwater Gulf of Mexico to provide a more efficient approach in identifying the top of cement on intermediate depth casing strings. Traditionally, the top of cement is determined by running cement bond logs, a time-consuming and costly process. Core's completion diagnostic engineers, in conjunction with two major deepwater operators, developed a technique by which the top of the cement is marked with Core's proprietary SpectraStim™ tracers. These tracers allow the operators to log the interval with their Logging While Drilling tools, thus eliminating the rig time and expense of running a separate cement bond log. The total cost savings realized by the operators were in excess of $150,000 per casing string. This application has now extended from two intermediate casing strings for the two original operators, to tracing three, and potentially four, intermediate casing strings. To date, this technology and resulting operational efficiency has been adopted by six deepwater operators.

Free Cash Flow and Dividend

During the fourth quarter of 2021, Core continued to generate free cash flow (“FCF”), with cash from operations of $7,200,000 and capital expenditures of $4,800,000, yielding FCF of $2,400,000. As revenue and business activities increase, Core's investment in working capital is also expected to increase. Capital expenditures for the fourth quarter of 2021 also include $1,000,000 associated with repairs of damaged facilities which are covered by insurance. Core’s free cash will continue to be returned to its shareholders via the Company’s regular quarterly dividend and opportunistic share repurchases, as well as being applied towards reducing long-term debt.

On 27 October 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 29 November 2021 to shareholders of record on 8 November 2021. Dutch withholding tax was deducted from the dividend at a rate of 15%.

On 2 February 2022, the Board approved a cash dividend of $0.01 per share of common stock payable in the first quarter of 2022. The first quarter dividend will be payable on 7 March 2022, to shareholders of record on 14 February 2022. 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.

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. Bloomberg’s calculations using the latest comparable data available indicate that Core Lab's ROIC of 9.8% is one of the highest for all major companies in the oilfield service Comp Group.

Industry and Core Lab Outlook and Guidance

The global crude-oil market continues to tighten, as demand for crude oil continues to approach pre-COVID levels, resulting in noticeable increases to crude-oil commodity prices. Current crude-oil commodity prices may also drive a higher level of investment, and urgency, in international offshore crude-oil development projects in 2022 and beyond. These crude-oil market fundamentals are reflected in the gradual increase in the international rig count, with more oilfield equipment coming under contract and expanded capital spending plans for 2022. Core sees this as a leading indicator of a growing international cycle.

With Core Lab having more than 70% of its revenue exposed to international activity, both business segments remain active on international projects. As additional field development projects emerge, wells need to be drilled and reservoir rock and fluid sampled before Reservoir Description more fully participates in the cycle. As pandemic disruptions abate, the expansion of international developments provides growth

opportunities for both segments into 2022 and beyond, with a particular focus on the South Atlantic Margin, Latin America, and the Middle East.

For the first quarter of 2022, Core Lab expects lower client activity due to seasonality. The seasonal pattern typically results in a decline in first quarter revenue by mid-single digits. The projected decline in first quarter revenue is slightly less pronounced, compared to historical trends, as the Company expects momentum in U.S. land activity to continue. As such, Core anticipates typical seasonal effects to impact the first quarter of 2022, with first quarter revenue down low to mid-single digits, sequentially.

Core projects first quarter 2022 revenue to range from $117,000,000 to $122,000,000 and operating income of $11,900,000 to $14,000,000, yielding operating margins of approximately 11%. EPS for the first quarter of 2022 is expected to be approximately $0.16 to $0.20.

The Company’s first quarter 2022 guidance is based on projections for underlying operations and excludes gains and losses in foreign exchange. First quarter 2022 guidance also assumes an effective tax rate of 20%.

Non-GAAP Information

Management believes that the exclusion of certain income and expenses enables it to evaluate more effectively the Company's operations period-over-period and to identify operating trends that could otherwise be masked by the excluded Items. For this reason, management uses certain non-GAAP measures that exclude these Items; and believes that this presentation provides a clearer comparison with the results reported in prior periods. The non-GAAP financial measures should be considered in addition to, and not as a substitute for, the financial results prepared in accordance with GAAP, as more fully discussed in the Company's financial statements and filings with the Securities and Exchange Commission.

Return on Invested Capital

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

ROIC of 9.8% is defined by Bloomberg as Net Operating Profit After Tax ("NOPAT") of $36.1 million divided by Average Total Invested Capital ("Average TIC") of $368.5 million where NOPAT 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 tax effect on income before interest and tax expense. Average TIC is defined as average of beginning and ending periods' 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.

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.
