Priorities:

Growth: following a period of optimization and strategic investment, the Company is on the cusp of a step change in profitability:

• Strategic investments are estimated to add approximately $1.8bn to EBITDA14,15 growth by the end of 2026. New projects expected to be commissioned in 2024 include: the cold rolling mill complex at Vega, additional capacity at Serra Azul mine and Barra Mansa (all in Brazil); the first phase of new Electrical Steels capacity in Europe; the first iron ore concentrate in Liberia; 1GW of renewable power capacity in India; and the new EAF at AMNS Calvert (US). In addition, the expansion of the AMNS India Hazira plant to ~15Mt capacity (Phase 1A) is progressing well and on track for completion in 2026 with Phase 1B Hazira capacity expansion to 20Mt planned; plans for expansion to 24Mt (including 1.5Mt long capacity) under preparation
• Decarbonized steel solutions: Existing capabilities in low-carbon metallics and EAF steel-making provide a unique competitive advantage as we offer an increasingly broad range of low-carbon intensity steel products to our customers. Our XCarb®   recycled and renewably12 produced steel continues to resonate with our customers, most recently exemplified by contracts to supply Vestas and Schneider Electric. Our DRI/EAF projects are progressing through FEED; we have signed contracts for a new 1.1Mt EAF at Gijon which will decarbonize the Long business in Spain, allowing for production of rails and quality wire rods; and a signed Letter of Intent with EDF for a long-term agreement to supply low carbon emissions power for our key French operations
• Progressive capital allocation: The Company’s defined capital allocation and return policy is working well, allowing the Company to develop and significantly grow its earnings capacity whilst consistently rewarding shareholders. The Board proposes to increase the annual base dividend to shareholders from $0.44/sh in FY 2023 to $0.50/sh (to be paid in 2 equal installments in June 2024 and December 2024), subject to the approval of shareholders at the 2024 AGM. In addition, the Company will continue to return a minimum 50% of post-dividend FCF to shareholders through its share buyback programs

Financial highlights (on the basis of IFRS1):

Commenting, Aditya Mittal, ArcelorMittal Chief Executive Officer, said:

“In October last year we committed to commissioning an independent 3rd party global audit of all our safety related practices and actions. This audit is now underway and I am determined its findings and recommendations, combined with the considerable efforts we are already implementing across the Group, will make us a safer and ultimately accident free company. Every employee in ArcelorMittal is aligned in this goal.

“Turning to our financial performance, our results for the full year reflect the benefits of the structural improvements we have made to our cost base, asset portfolio and balance sheet in recent years. Despite the operating environment becoming increasingly challenging as the year progressed, our profitability per tonne is healthy and well above long-term averages. This highlights the enhanced sustainability we have built into the business, enabling us to generate healthy cash flow to invest for future growth and return attractive levels of capital to our shareholders.

"Looking ahead, there are early signs of a more constructive industry backdrop. This, alongside the progress we are making with our portfolio of strategic growth projects - several of which will complete this year - means the Company will continue to take important steps forward in its drive to be a stronger, more profitable, and of course safer, Company."

Safety and sustainable development

Health and safety

Performance in 2023 was severely impacted by the tragic Kostenko mine accident on October 28, 2023.

In December 2023, ArcelorMittal launched an independent 3rd party global audit that will look at every aspect of the Company’s health and safety practices across the Group. ArcelorMittal's employees are united in their determination to become a zero fatality workplace and this audit will complement the considerable effort already being implemented across the organization to achieve this aim.

The Company-wide audit of safety practices by dss+ has now commenced and will support our pathway to zero serious injuries and fatalities. Recommendations are due to be published in September 2024 and the audit will cover:

• A comprehensive Fatality Prevention Standards audit for the 3 main occupational risks (crushed by vehicle, crushed by moving machinery & fall from height) leading to serious injuries and fatalities.
• Expert input into the CTO-led process risk management safety system that will include audits of its highest priority countries and assets (including strategic JVs).
• Assessment of all health and safety systems, processes, structures, capabilities, governance and assurance processes.

Own personnel and contractors – Lost Time Injury Frequency rate

Sustainable development highlights:

• In Spain, on November 28, 2023, ArcelorMittal announced that contracts have been signed to build a new 1.1Mt EAF in Gijon. Once the EAF is operational (1H 2026), the site will be able to switch to producing low carbon-emissions steel for the long products sector, rails and wire rods, making the site highly competitive, in particular for sectors with stringent carbon criteria for public procurement contracts.
• In France, on January 15, 2024, a Letter of Intent was signed with EDF for the long-term supply of low carbon electricity to its French steelmaking sites in Dunkirk and Fos-sur-Mer (subject to final approvals for the DRI/EAF project in Dunkirk).
• ArcelorMittal has seen increasing demand for its low carbon steel – XCarb® recycled and responsibly produced steel.
  • On November 15, 2023, Schneider Electric and ArcelorMittal announced a partnership to supply XCarb® recycled and renewably produced steel for Schneider Electric’s electrical cabinets and enclosures.
  • On January 16, 2024, Vestas and ArcelorMittal announced a low carbon partnership and the first project will use XCarb® recycled and renewably produced heavy plate steel for an offshore wind farm, built by Baltic Power in Poland.
• In India, AM/NS India published their Climate Action report and are targeting a reduction in their emissions intensity of 20% by 2030 (from 2021 levels).
• Over the course of 2023, ArcelorMittal has also progressed renewable projects in Argentina, India and Brazil, announced plans to build an industrial- scale direct electrolysis plant (Volteron™) and has been advancing smart carbon projects in Ghent and Dunkirk (Carbon Capture and Storage pilots and the Steelanol plant).
• Following the sale of the Company's assets in Kazakhstan (which represented approximately 16.5% of the Group's scope 1 and scope 2 carbon emissions), the Company no longer owns and operates coal mines.

Analysis of results for the twelve months ended December 31, 2023 versus results for the twelve months ended December 31, 2022

Sales for 12M 2023 decreased by -14.5% to $68.3 billion as compared with $79.8 billion for 12M 2022, primarily due to -13.5% lower average steel selling prices as shipments were relatively stable.

Impairment charges (other than related to the sale of operations in Kazakhstan) for 12M 2023 amounted to $0.1 billion, relating to the Long business of ArcelorMittal South Africa as compared to an impairment charge of $1.0 billion in 12M 2022 related to ArcelorMittal Kryvyi Rih (Ukraine).

Following the sale of the Company's steel and mining operations in Kazakhstan, the Company recorded a $0.9 billion non-cash impairment charge (including $0.2 billion goodwill), and recorded $1.5 billion cumulative translation losses (previously recorded against equity) through the profit and loss.

Operating income for 12M 2023 of $2.3 billion was lower as compared to $10.3 billion in 12M 2022 primarily driven by negative price-cost effect (predominantly on account of -13.5% lower average steel selling prices), impairment charges and impact on disposal of Kazakhstan operations as discussed above.

Income from associates, joint ventures and other investments (excluding impairment) for 12M 2023 was stable at $1.2 billion as compared to $1.3 billion for 12M 2022 supported by higher contributions from AMNS India and Chinese investees.

Impairment of associates, joint ventures and other investments amounted to $1.4 billion for 12M 2023, and related to the impairment of the Company’s investment in Acciaierie d'Italia (ADI) following downward revisions to the expected future cash flows.

ArcelorMittal’s net income for 12M 2023 was $919 million as compared to $9,302 million for 12M 2022. Adjusted net income9 for 12M 2023 was $4.9 billion as compared to $10.6 billion for 12M 2022.

ArcelorMittal’s basic earnings per common share for 12M 2023 was $1.09, as compared to $10.21 for 12M 2022. Adjusted basic earnings per common share (excluding impairment charges and impact on disposal of Kazakhstan operations)9 for 12M 2023 was $5.78 as compared to $11.65 for 12M 2022.

Analysis of results for 4Q 2023 versus 3Q 2023

Sales in 4Q 2023 were -12.4% lower at $14.6 billion as compared to $16.6 billion in 3Q 2023 impacted by lower average steel selling prices (-5.1%) and lower steel shipment volumes (-3.0%).

Impairment charges (other than related to the sale of operations in Kazakhstan) for 4Q 2023 amounted to $0.1 billion related to the Long business of ArcelorMittal South Africa.

Following the sale of the Company's steel and mining operations in Kazakhstan the Company recorded a $0.9 billion non-cash impairment charge (including $0.2 billion goodwill) and recorded $1.5 billion cumulative translation losses (previously recorded against equity) through the profit and loss.

Operating loss for 4Q 2023 was $2.0 billion as compared to an operating income of $1.2 billion in 3Q 2023. The operating loss in 4Q 2023 was impacted by the impairment and impact on disposal of Kazakhstan operations (as discussed above), and also reflected a decline in steel spreads (primarily due to a decline in steel prices) and lower steel shipments.

Income from associates, joint ventures and other investments (excluding impairments) for 4Q 2023 was lower at $188 million as compared to $285 million in 3Q 2023, primarily due to lower contributions from European investees.

Impairments of associates, joint ventures and other investments were $1.4 billion for 4Q 2023, and related to the impairment of the Company’s investment in Acciaierie d'Italia (ADI) following downward revisions to the expected future cash flows.

ArcelorMittal recorded net loss in 4Q 2023 of $2,966 million as compared to a net income of $929 million in 3Q 2023. Adjusted net income9 in 4Q 2023 was $982 million as compared to $929 million in 3Q 2023.

Analysis of segment operations

NAFTA

* NAFTA steel shipments include slabs sourced by the segment from Group companies (mainly the Brazil segment) and sold to the Calvert JV (eliminated in the Group consolidation). These shipments can vary between periods due to slab sourcing mix and timing of vessels. 4Q'23 432kt, 3Q'23 393kt, 4Q'22 272kt, 12M'23 1,660kt and 12M'22 1,173kt

Sales in 4Q 2023 decreased by -7.7% to $2.9 billion, as compared to $3.2 billion in 3Q 2023 primarily on account of lower average steel selling prices (-9.1%) offset in part by higher steel shipments (+2.5%).

Operating income in 4Q 2023 decreased by -46.3% to $280 million as compared to $520 million in 3Q 2023, due to a negative price-cost effect, primarily due to lower average steel selling prices.

EBITDA in 4Q 2023 of $437 million was -32.2% lower as compared to $645 million in 3Q 2023, primarily due to a negative price-cost effect, resulting primarily from lower average steel selling prices.

Brazil10

Since its consolidation on March 9, 2023, ArcelorMittal Pecém has performed strongly, achieving full nameplate production and capturing synergies of ~$0.1 billion, double the pre-acquisition forecast.

Sales in 4Q 2023 decreased by -23.9% to $2.7 billion as compared to $3.6 billion in 3Q 2023, primarily due to a -8.6% decrease in average steel selling prices and translation impacts from the devaluation of the Argentinian peso.

Operating income in 4Q 2023 of $171 million was -58.6% lower as compared to $414 million in 3Q 2023 primarily due to a negative price-cost effect and the devaluation of the Argentinian peso as discussed above.

EBITDA in 4Q 2023 decreased by -50.4% to $248 million as compared to $501 million in 3Q 2023 due to negative price-cost effect and the negative impact of Argentinian peso devaluation (approximately $80 million).

Europe

Europe segment crude steel production decreased by -11.3% to 6.6Mt in 4Q 2023 as compared to 7.5Mt in 3Q 2023 impacted by a reline of BF#A at Gent (Belgium) and planned maintenance of BF#2 at Bremen (Germany) both of which restarted in early December 2023 and coupled with production cuts at BF1 in Fos (France). Steel shipments were stable in 4Q 2023 as compared to 3Q 2023 primarily due to continued weak apparent demand driven by destocking and construction-related demand.

Sales in 4Q 2023 declined by -10.2% to $8.0 billion, as compared to $8.9 billion in 3Q 2023, primarily due to -4.4% decrease in average steel selling prices.

Operating income in 4Q 2023 of $11 million as compared to operating income of $160 million in 3Q 2023 mainly due to a negative price-cost effect.

EBITDA in 4Q 2023 of $336 million decreased by -28.9% as compared to $473 million in 3Q 2023, mainly due to a negative price-cost effect.

ACIS

On December 7, 2023, the Company completed the sale of its Kazakhstan operations.

On a scope adjusted basis, i.e. excluding Kazakhstan, crude steel production in 4Q 2023 was 0.9Mt, a decrease of -23.1% as compared 3Q 2023 due to maintenance work at ArcelorMittal South Africa. On a scope adjusted basis steel shipments in 4Q 2023 were 0.9Mt, a decrease of -8.1% as compared to 3Q 2023.

Sales in 4Q 2023 declined by -13.7% to $1.2 billion as compared to $1.4 billion in 3Q 2023, primarily due to lower steel shipments, resulting primarily from the disposal of the Kazakhstan operations on December 7, 2023 as mentioned above.

Impairment charges for 4Q 2023 (other than related to the sale of Kazakhstan operations) amounted to $0.1 billion, relating to the Long business of ArcelorMittal South Africa and the impact on disposal of Kazakhstan operations was a loss of $2.4 billion6. The Company is to receive $1.0 billion aggregate proceeds from the sale; consideration of $536 million has been received and a further $450 million is to be received in four equal installments starting 2Q 2024 (with sovereign fund guarantees).

Operating loss in 4Q 2023 of $2,689 million (impacted by impairment and the impact on disposal of Kazakhstan operations) compared to $92 million in 3Q 2023.

EBITDA loss was $84 million in 4Q 2023 as compared to $21 million in 3Q 2023 primarily due to lower steel shipments and average steel selling prices.

Mining

Note: Mining segment comprises iron ore operations of ArcelorMittal Mines Canada (AMMC) and ArcelorMittal Liberia.

Operating income in 4Q 2023 was -1.7% lower at $270 million as compared to $275 million in 3Q 2023.

EBITDA in 4Q 2023 of $339 million was +2.1% higher as compared to $332 million in 3Q 2023, due to higher iron ore reference prices (+12.8%) offset in part by lower iron ore shipments (-4.1% due in part to the impact of a rail bridge failure in Liberia in early November 2023 as well as lower production at AMMC due to maintenance), higher freight costs and lower quality premia.

Joint ventures

ArcelorMittal has investments in various joint ventures and associate entities globally. The Company considers the Calvert (50% equity interest) and AMNS India (60% equity interest) joint ventures to be of particular strategic importance, warranting more detailed disclosures to improve the understanding of their operational performance and value to the Company.

Calvert

Calvert EBITDA during 4Q 2023 of $90 million represented a -14.6% decline as compared to $105 million in 3Q 2023 primarily due to a weaker mix with a lower percentage of higher margin automotive shipments and higher maintenance costs.

AMNS India

AMNS India achieved record crude steel production in December 2023 reaching 8.1Mt run-rate (close to 8.6Mt capacity debottlenecking target).

The CGL4 line was commissioned in 4Q 2023 which allowed for the launch of the Magnelis product (renewables and solar products) into the market.

EBITDA during 4Q 2023 of $499 million was -6.4% lower as compared to $533 million in 3Q 2023, including a lower impact from natural gas hedges.

Outlook

As anticipated, apparent demand conditions are now showing signs of improvement as the destocking phase reaches maturity. Despite continued headwinds to real demand, World ex-China apparent steel consumption ("ASC") in 2024 is expected to grow by +3.0% to +4.0% as compared to 2023.

ArcelorMittal expects the following demand dynamics by key region:

• In the US, although real demand growth is expected to remain lackluster due to the lagged impact of higher interest rates, the destocking that impacted apparent demand in 2023 is not expected to continue in 2024. As a result, apparent steel consumption of flat products is expected to grow by +1.5% to +3.5%;
• In Europe, whilst the Company assumes a marginal decline in real demand, mainly construction, the destocking that impacted apparent demand in 2023 is not expected to continue in 2024. As a result, apparent demand for flat products is expected to improve, with growth within a range of +2.0% to +4.0%;
• In Brazil, the Company expects a gradual rebound in real steel consumption to support an ASC growth within a range of +0.5% to +2.5%;
• In India, the Company expects another strong year with apparent steel consumption growth within the range of +6.5% to +8.5%;
• In China, economic growth is expected to weaken. Despite continued weakness in real estate, the impact of announced stimulus is expected to support offsetting demand growth from infrastructure spending. As a result, steel consumption is expected to be relatively stable/slightly positive (+0% to +2%).

The Company remains positive on the medium/long-term steel demand outlook and, supported by its strong position remains focused on executing its strategy of growth with capital returns.

Capex in 2024 is expected to remain within the $4.5-$5.0 billion range (of which $1.4-$1.5 billion is expected as strategic growth capex).

New segmentation and incorporating the result from investments in associates, joint ventures and other investments into EBITDA from January 1, 2024

Going forward we will report EBITDA including our share of JV and associates net income in order to more fully reflect our growth exposures. EBITDA will be defined as operating income (loss) plus depreciation, impairment charges, exceptional items and income from associates, JV and other investments (excluding impairment charges and exceptional items, if any, of such associates, joint ventures and other investments). The following changes will be made to the Company's segment reporting:

• The NAFTA segment will be renamed "North America", a core growth region for the ArcelorMittal Group;
• "India and JVs” will be reported separately as a segment, reflecting the share of net income of AMNS India, VAMA and Calvert as well as the other associates, joint ventures and other investments. India is a high growth vector of the Group and our assets have strategic advantages to grow in line with the market and increase profitability;
• "Sustainable Solutions" segment will be composed of a number of high-growth, niche, capital light businesses playing an important role in supporting climate action (including renewables, special projects and construction business) which are currently reported within the Europe segment, which will be reported separately;
• Following the sale of the Company’s operations in Kazakhstan, the remaining parts of the former ACIS segment will be assigned to an “Others” segment; and
• No changes to the "Brazil" and "Mining" segments.

These changes will be applied as from January 1, 2024, and will be presented with the earnings release for the first quarter of 2024. The Company will in due course publish historical comparative information for modelling purposes.

ArcelorMittal also presents adjusted net income(loss) and adjusted basic earnings per share as it believes these are useful measures for the underlying business performance excluding impairment items, exceptional items. The definition of adjusted net income has been revised as for EBITDA to split out the impairment charges and exceptional items of the Kazakhstan disposal for the same reason as for EBITDA and also to clarify that impairment charges and exceptional items of associates, joint ventures and other investments are excluded from this alternative performance measure. The Company’s guidance as to additional EBITDA estimated to be generated from certain projects, free cash flow, cash taxes and its working capital release (or the change in working capital included in net cash provided by operating activities) for 2023 is based on the same accounting policies as those applied in the Company’s financial statements prepared in accordance with IFRS. ArcelorMittal is unable to reconcile, without unreasonable effort, such guidance to the most directly comparable IFRS financial measure, due to the uncertainty and inherent difficulty of predicting the occurrence and the financial impact of items impacting comparability. For the same reasons, ArcelorMittal is unable to address the significance of the unavailable information. Non-GAAP financial/alternative performance measures should be read in conjunction with, and not as an alternative to, ArcelorMittal's financial information prepared in accordance with IFRS.
2. LTIF refers to lost time injury frequency rate equals lost time injuries per 1,000,000 worked hours, based on own personnel and contractors. LTIF figures: 12M 2023 0.92 and 12M 2022 0.70.
3. ROE refers to "Return on Equity" which is calculated as trailing twelve-month adjusted net income (excluding impairment charges and exceptional items) attributable to equity holders of the parent divided by the average equity attributable to the equity holders of the parent over the period. 2023 ROE of 8.9% ($4.9 billion / $54.4 billion). 2022 ROE of 20.3% ($10.6 billion / $52.3 billion).
4. Equity book value per share is calculated as the Equity attributable to the equity holders of the parent divided by diluted number of shares at the end of the period. 4Q 2023 total equity of $54.0 billion divided by 819 million shares outstanding equals $66/sh. 3Q 2023 total equity of $55.4 billion divided by 838 million diluted shares outstanding equals $66/sh.
5. Impairment charge for 12M 2023 (excluding that related to the sale of operations in Kazakhstan) amounted to $0.1 billion, related to the Long business of ArcelorMittal South Africa. Impairment charge of $1.0 billion in 12M 2022 related to ArcelorMittal Kryvyi Rih (Ukraine).
6. Exceptional items for 12M 2023 (excluding that related to the sale of operations in Kazakhstan) were nil. Exceptional items for 12M 2022 of $0.3 billion included non-cash inventory related provisions partially offset by gains related to the acquisition of the Hot Briquetted Iron (‘HBI’) plant in Texas and the settlement of a claim by ArcelorMittal for a breach of a supply contract. Following the sale of the Company's steel and mining operations in Kazakhstan the Company recorded a $0.9 billion non-cash impairment charge (including $0.2 billion goodwill), and recorded $1.5 billion cumulative translation losses (previously recorded against equity) through the Consolidated Statements of Operations.
7. FY 2022 FCF of $6.4 billion ($10.2 billion net cash provided by operating activities less capex of $3.5 billion less minority dividends of $0.3 billion).
8. September 30, 2020, was the inception date of the ongoing share buyback programs.

10. On March 9, 2023, ArcelorMittal announced that following receipt of customary regulatory approvals it has completed the acquisition of Companhia Siderúrgica do Pecém (‘CSP’) in Brazil for an enterprise value of approximately $2.2 billion. CSP has since been renamed ArcelorMittal Pecém and is a world-class operation, producing high-quality slab at a globally competitive cost. Its facility, located in the state of Ceará in northeast Brazil was commissioned in 2016. It operates a three million tonne capacity blast furnace and has access via conveyors to the Port of Pecém, a large-scale, deep-water port located 10 kilometers from the plant. The acquisition offers significant operational and financial synergies and brings with it the potential for further expansions, such as the option to add primary steelmaking capacity (including direct reduced iron) and rolling and finishing capacity. Given its location, ArcelorMittal Pecém also presents an opportunity to create a new low-carbon steelmaking hub, capitalizing on the state of Ceará’s ambition to develop a low-cost green hydrogen hub in Pecém.
11. Company has repurchased 45.4 million shares during 12M 2023 including 26.3 million shares from the current 85 million share buy back program.
12. XCarb® is designed to bring together all of ArcelorMittal’s reduced, low and zero-carbon products and steelmaking activities, as well as wider initiatives and green innovation projects, into a single effort focused on achieving demonstrable progress towards carbon neutral steel. Alongside the new XCarb® brand, we have launched three XCarb® initiatives: the XCarb® innovation fund, XCarb® green steel certificates and XCarb® recycled and renewably produced for products made via the Electric Arc Furnace route using scrap. The Company is offering green steel using a system of certificates (XCarb® green certificates). These will be issued by an independent auditor to certify tonnes of CO2 savings achieved through the Company’s investment in decarbonization technologies in Europe. Net-zero equivalence is determined by assigning CO2 savings certificates equivalent to CO2 per tonne of steel produced in 2018 as baseline. The certificates will relate to the tonnes of CO2 saved in total, as a direct result of the decarbonization projects being implemented across a number of its European sites.
13. On December 19, 2018, ArcelorMittal signed a $5.5 billion Revolving Credit Facility ("RCF"), with a five-year maturity plus two one-year extension options. During the fourth quarter of 2019, ArcelorMittal executed the option to extend the facility to December 19, 2024 for an available amount of $5.4 billion. After the extension the remaining $0.1 billion remained with a maturity of December 19, 2023 and has hence expired. In December 2020, ArcelorMittal executed the second option to extend the facility, and the new maturity is now extended to December 19, 2025. On April 30, 2021, ArcelorMittal amended its $5.5 billion RCF to align with its sustainability and climate action strategy. On December 20, 2022, the RCF was amended as part of the transition from Libor to risk free rates. Loans in USD are now based on Term SOFR instead of Libor. As of December 31, 2023, the $5.4 billion revolving credit facility was fully available.
14. Estimate of additional contribution to EBITDA, based on assumptions once ramped up to capacity and assuming prices/spreads generally in line with the averages of the 2015-2020 period. The $1.8 billion total also includes the expected share of net income from key strategic growth projects in AMNS India and Calvert (US).
15. New segmentation from January 1, 2024: In order to better reflect the business profile and external understanding of its geographical and market exposures, the Company will going forward refer to EBITDA (defined as operating income (loss) plus depreciation, impairment items and exceptional items and income from associates, joint ventures and other investments (excluding impairments and exceptional items if any, of associates, joint ventures and other investments). The following changes will be made to the Company's reporting: a) The NAFTA segment will be renamed "North America", a core growth region for the ArcelorMittal Group; b) "India and JVs” will be reported separately as a segment, reflecting the share of net income (excluding impairment charges) of AMNS India, VAMA and Calvert as well as the other associates, joint ventures and other investments. India is a high growth vector of the Group and we believe our assets have strategic advantages to grow in line with the market and increase profitability; c) "Sustainable Solutions" segment will be composed of a number of high-growth, niche, capital light businesses playing an important role in supporting climate action (including renewables, special projects and construction business) which are currently reported within the Europe segment, will be reported separately; d) Following the sale of the Company’s operations in Kazakhstan, the remaining parts of the former ACIS segment will be assigned to an “Others” segment; and e) No changes to the "Brazil" and "Mining" segments. These changes will be applied as from January 1, 2024 and will be presented with the earnings release for the first quarter of 2024. The Company will in due course publish historical comparative information for modelling purposes.
16. Impairments of associates, joint ventures and other investments were $1.4 billion for 12M 2023, and relate to the impairment of the Company’s investment in Acciaierie d'Italia (ADI) following downward revisions to the expected future cash flows.
17. Production: all production of the hot strip mill including processing of slabs on a hire work basis for ArcelorMittal Group entities and third parties, including stainless steel slabs. Shipments: including shipments of finished products processed on a hire work basis for ArcelorMittal Group entities and third parties, including stainless steel products. EBITDA of Calvert presented here on a 100% basis as a stand-alone business and in accordance with the Company's policy, applying the weighted average method of accounting for inventory.
18. Net cash provided by operating activities in 4Q 2023 was $3,328 million, and includes a working capital release of $2,470 million as compared to an investment of $269 million, driven primarily by lower accounts receivable (due to lower prices and lower volumes, including the impact of normal seasonality at year end), and lower inventories (primarily due to reduced inventory volumes). The Company released a total of $1,604 million in working capital in the calendar year 2023.
19. Excluding impact on disposal of Kazakhstan operations.
