AMSTERDAM (1 February 2023) - Core Laboratories N.V. (NYSE: "CLB") ("Core", "Core Lab", or the "Company") reported fourth quarter 2022 revenue of $127,600,000. Core’s operating income was $15,600,000, with diluted earnings per share ("EPS") of $0.14, all in accordance with U.S. generally accepted accounting principles ("GAAP"). The financial results for the fourth quarter of 2022 include a non-cash adjustment of $1,900,000, decreasing stock compensation expense associated with performance share awards that vested during the quarter. Operating income, ex-items, a non-GAAP financial measure, was $14,700,000, yielding operating margins of 12%, and EPS, ex-items, of $0.20. A full reconciliation of non-GAAP financial measures is included in the attached financial tables.

For 2022, Core’s revenue of $489,700,000 increased 4% from the prior year. Core’s full-year revenue was adversely impacted by the devaluation of the Euro and British Pound when translated into U.S. dollars. Using a constant U.S. dollar exchange rate, 2022 revenue would have been approximately $12,800,000 higher. In addition, Core’s 2022 revenue was also adversely impacted by the Russia-Ukraine conflict. Across Core’s European, Russian and Ukrainian operations, activity declined due to disruptions in crude-oil trading patterns, causing the Company’s crude-oil assay and derived product testing revenue and product sales to decline in excess of $10,000,000 year-over-year. The combined impact of these currency fluctuations and geopolitical factors adversely impacted 2022 revenue by approximately $22,800,000 year-over-year, substantially offsetting international growth in other regions.

Core’s CEO, Larry Bruno stated, “First, our thoughts remain with our Ukrainian employees and their families during the on-going conflict. Despite the challenges posed by currency and geopolitical conflict, Core's

results during the fourth quarter of 2022 displayed continued positive momentum, as we achieved sequential improvement in revenue, operating income, operating margins and EPS, with strong incremental margins. These improvements translated into higher free cash flow (“FCF”), which enabled the Company to decrease net debt by $11,700,000 or 7%, sequentially. Core remains intently focused on executing against its key financial and operational strategies, including 1) reducing debt and strengthening our balance sheet, as well as 2) consistently pursuing efficiencies and the introduction of new technologies. For 2023, Core sees the continuation of a multi-year recovery cycle for the oil and gas industry led by improvement in both onshore and offshore client activity across our global operations, although the Russia-Ukraine conflict continues to create volatility and uncertainties to growth prospects in Europe, Russia and Ukraine."

Voluntary Delisting from Euronext and Redomestication to the United States

On 4 November 2022, Core Lab announced its decision to voluntarily delist its shares from Euronext Amsterdam, and the last trading day for the Company’s shares on the Euronext was 2 December 2022. The Company’s shares continue to trade on the New York Stock Exchange under the symbol “CLB”.

Following the delisting of the shares, on 17 January 2023, Core Lab announced plans to reorganize the Company’s corporate structure, resulting in the redomestication of the parent company from the Netherlands to the United States (the “Redomestication”). The Company and its Board believes that the Redomestication will enhance shareholder value over the long-term through simplifying the corporate structure, improving operational efficiencies and reducing administrative costs. The Redomestication, if approved by the Company's shareholders, will change the Company’s jurisdiction of organization from the Netherlands to the State of Delaware.

Benefits of the Redomestication include: (i) a reduction in the corporate footprint and regulatory requirements associated with preparing duplicative audited financial statements and other reporting obligations, (ii) improved efficiencies and opportunities in the Company’s corporate treasury, cash management, risk management and tax functions, and (iii) a simplified and more efficient tax structure.

Reservoir Description

Reservoir Description operations are closely correlated with trends in international and offshore activity levels, with approximately 80% of revenue sourced from projects originating outside the U.S. Reservoir Description revenue in the fourth quarter of 2022 was $78,100,000, down slightly sequentially and year-over-year. Geopolitical sanctions that became effective during the fourth quarter of 2022, further disrupted trading patterns of crude oil and derived products in Europe, Russia and Ukraine. As a result, the demand for laboratory services in the fourth quarter of 2022 was adversely impacted, offsetting revenue growth in other international regions. Operating income for the fourth quarter of 2022 on a GAAP basis was $6,800,000, while operating income, ex-items, was $6,000,000, yielding operating margins of 8%.

Reservoir Description revenue for 2022 was adversely impacted by the devaluation of the Euro and British Pound when translated into U.S. dollars. Using a constant U.S. dollar exchange rate, Reservoir Description 2022 revenue would have been approximately $12,000,000 higher. For 2022, revenue was also adversely impacted by the Russia-Ukraine conflict, declining over $9,000,000 compared to 2021. Combined, these

two factors adversely impacted Reservoir Description 2022 revenue by approximately $21,000,000, substantially offsetting international growth in other regions.

During the fourth quarter of 2022, under the direction of a South American National Oil Company, Core Lab conducted a series of Enhanced Oil Recovery (“EOR”) and flow assurance studies for a multi-well onshore program using CO2-rich injection gases. The studies determined the impact of blending these CO2-rich gases with reservoir fluids and provided the basis for advanced equation-of-state modelling. While defining the gas injection parameters for a successful field application are critical to improving crude oil recoveries, operators must simultaneously mitigate the flocculation of asphaltenes that result from CO2 injection, and which, can erase such gains. CO2 injection projects reflect a globally expanding interest in EOR and Carbon Capture and Storage technologies. When properly evaluated with rigorous laboratory testing, injecting CO2 into hydrocarbon-bearing subsurface formations can simultaneously improve oil recovery and reduce CO2 emissions.

Also, during the fourth quarter of 2022, Core received both reservoir fluid and reservoir rock samples from Talos Energy Inc.’s Deepwater Gulf of Mexico Lime Rock and Venice prospects. Leveraging Core’s experience with prior successful Gulf of Mexico drilling campaigns, the Company was able to quickly implement laboratory analytical protocols to fast-track results and evaluate reservoir potential within days of receiving the samples. The analytical results provided key reservoir parameters including: 1) an assessment of the pore system and fluid flow properties of these high-quality sandstone strata, 2) measurement of the crude oil and natural gas saturations in the recovered rocks, and 3) determination of key reservoir fluid properties such as the gas-oil ratio, and with the composition of the hydrocarbons. Talos’ experts incorporated these parameters into their assessment of the commercial viability of these prospects. Core’s proprietary high pressure, high temperature, full visualization Pressure-Volume-Temperature technologies, along with the Company's extensive database of producing reservoirs in the Gulf of Mexico, helped Talos in this successful drilling 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 projects across the globe, posted fourth quarter 2022 revenue of $49,400,000, increasing over 5% sequentially and 10% year-over-year. Operating income on a GAAP basis was $7,900,000, while operating income, ex-items, was $7,700,000, yielding operating margins of 16% and sequential incremental margins, ex-items, in excess of 100%. In addition, Core’s proprietary diagnostic services grew over 22% sequentially and 17% year-over-year.

During the fourth quarter of 2022, a U.S.-based operating company expressed the need to overcome injectivity challenges in their saltwater disposal wells. Cost-effective disposal of produced frac fluid is critical to the financial success of unconventional resources. Reservoir modeling determined that to optimize injection efficiencies, 14 zones dispersed across a 1,700 ft lateral wellbore needed to be perforated simultaneously in an over-balanced pressure configuration. Core Lab provided a customized solution for this challenging technical problem by combining its proprietary Pulse Wave™ Tubular Conveyed System with its proprietary HERO® Hard Rock energetics. Pulse Wave™ uses a unique energy transfer technology that can trigger multiple, unevenly-spaced perforating guns in a single downhole trip, eliminating the need for inert spacer guns between live guns to create a continuous communication string.

Eliminating the need for spacer guns reduces material cost and significantly reduces the rig time required to deploy the system. The HERO® Hard Rock energetic technology uses an advanced, patented, liner material technology that yields debris-free perforations, while also providing deep penetration and more effective flow efficiencies in hard rock formations. By employing Pulse Wave™ technology, the client saved over 30% on the cost of consumables, in addition to reduced rig time. The HERO® Hard Rock energetics created communication across each perforating interval, enabling the operator to establish the desired injection rate, which was double that of similar wells completed using conventional wireline perforating technologies.

Liquidity, Free Cash Flow and Dividend

Core continues to focus on maximizing FCF, a non-GAAP financial measure defined as cash from operations less capital expenditures. For the fourth quarter of 2022, cash from operations was $13,200,000 and capital expenditures were $2,000,000, yielding FCF of $11,200,000. Core’s free cash will continue to be returned to its shareholders through the Company’s regular quarterly dividend as well as being focused towards reducing long-term debt.

During the fourth quarter of 2022, Core’s net debt was reduced by $11,700,000, which also reduced the Company’s leverage ratio to 2.29 as of 31 December 2022, down from 2.42 at the end of third quarter of 2022. The Company will continue applying free cash towards reducing debt until the Company reaches its target leverage ratio (calculated as total net debt divided by trailing twelve months adjusted EBITDA) of 1.5 times or lower.

On 26 October 2022, Core’s Board of Supervisory Directors ("Board") announced a quarterly cash dividend of $0.01 per share of common stock, which was paid on 28 November 2022 to shareholders of record on 7 November 2022. Dutch withholding tax was deducted from the dividend at a rate of 15%.

On 1 February 2023, the Board approved a cash dividend of $0.01 per share of common stock payable on 6 March 2023 to shareholders of record on 13 February 2023. 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 promotes capital efficiency and is 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 Core Lab's ROIC improved to 7.2%.

Industry and Core Lab Outlook and Guidance

Looking forward into 2023, Core sees crude-oil macro fundamentals continuing to support a multi-year recovery cycle for the oil and gas industry. Crude-oil demand for 2023, as forecast by the International Energy Agency in January 2023, is projected to increase by 1.9 million barrels per day (“mbpd”) to a record 101.7 mbpd as consumption in China grows along with the reopening of its economy. As crude-oil demand is projected to exceed pre-COVID levels, crude-oil supply is projected to tighten. Production growth continues to face constraints due to prolonged underinvestment in many regions around the globe and the natural decline of production from existing fields. As a result, Core Lab expects operators to expand their upstream spending plans for 2023 by mid-teens compared to 2022. This supports Core's outlook for continued improvement in international onshore and offshore activity, with projects emerging and underway, most notably across the Middle East, Latin America and West Africa regions.

Turning to the U.S., Core sees similar challenges with crude-oil supply which should require increased spending by operators to grow and replace production. While operators remain focused on capital discipline, 2023 forecasts indicate their U.S. upstream spending will increase approximately 15% year-over-year.

As customary, Core expects typical sequential seasonal industry patterns will cause activity in the first quarter of 2023 to decline in some regions. As such, Core anticipates Reservoir Description first quarter 2023 revenue to be down low to mid-single digits, sequentially. Continued volatility with crude-oil trading patterns may impact Core’s Reservoir Description segment’s international growth within its Russian, Ukrainian and European operations. Production Enhancement segment revenue is estimated to be up mid-single digits as U.S. land activity is projected to recover from normal seasonal declines experienced at year-end.

Core projects first quarter 2023 revenue to range from $125,000,000 to $129,000,000 and operating income of $11,500,000 to $14,500,000, yielding operating margins of approximately 10%. EPS for the first quarter of 2023 is expected to be $0.14 to $0.19.

The Company’s first quarter 2023 guidance is based on projections for underlying operations and excludes gains and losses in foreign exchange. First quarter 2023 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 7.2% is defined by Bloomberg as Net Operating Profit After Tax ("NOPAT") of $26.8 million divided by Average Total Invested Capital ("Average TIC") of $372.9 million where NOPAT is defined as GAAP net income before non-controlling 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 the average of beginning and ending periods' GAAP stockholders' equity plus the sum of net long-term debt, lease liabilities, allowance for credit losses, net of deferred taxes, and income taxes 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.
