Consolidated Table - Highlights

¹ Adjusted EBITDA is calculated from net income
(loss) plus depreciation and amortization, income taxes, net financial income, income from investments, income from other operating income/expenses
and includes the proportional 37.49% share of EBITDA of the jointly owned subsidiary MRS Logística.
² The Adjusted EBITDA Margin is calculated as
Adjusted EBITDA divided by Management Net Revenue.
³ Adjusted Net
Debt and Adjusted Cash/Availabilities consider 37.49% of MRS, in addition to not considering Forfaiting and Drawn Risk operations.
Consolidated Results
| · | Net Revenues totaled
R$ 12,026 million in 4Q24, which represents growth of 8.7% when compared to the previous quarter and mainly reflects a better price realization
in mining amid the recovery of the Platts price. In addition, the steel segment continued to show solid commercial activity, with a 10.4%
increase in sales volume compared to 4Q23, contributing positively to the increase in revenues in the period. In 2024, Net Revenue totaled
R$ 43,687 million, which corresponds to an annual reduction of 3.9%, reflecting the reduction in the average iron ore price over the year.
|
| · | Cost of Goods Sold (COGS)
totaled R$ 8,243.1 million in 4Q24, down 1.1% on the previous quarter, reflecting cost reductions in the steel and cement segments.
In 2024, COGS totaled R$ 31,991 million, which represents a reduction of 4.4% in relation to the previous year and mainly reflects the
lower quantity of iron ore purchases from third parties. |
| · | In turn, Gross Profit in
4Q24 reached R$ 3,783 million, an increase of 38.4% over the previous quarter, with a Gross Margin of 31.5%, which corresponds to a solid
increase of 6.8 p.p. over the previous quarter. This higher profitability reflects strong revenue growth in mining, with greater cost
control in steel and cement. In 2024, Gross Profit was R$ 11,697 million with a Gross Margin of 26.8%, an increase of 0.4 p.p. compared
to the previous year. |
| · | Selling, general and administrative
expenses totaled R$ 1,608 million in 4Q24 and were 5.9% lower than in the previous quarter, but 32.6% higher when compared to the
same period of last year. This quarter-on-quarter drop mainly reflects the seasonality of the mining operation, while the year-on-year
increase is the result of greater dynamism in the cement sector. In 2024, Selling, General and Administrative Expenses reached
R$ 6.309 million, which represents an increase of 40.5% when compared to the same period of last year. |
| · | In 4Q24, the group of Other
Revenues and Operating Expenses recorded a negative balance of R$ 1,016 million, which corresponds to an increase of R$ 650 million
over the previous quarter. This impact was driven by the effect of hedge accounting, in line with the schedule of exports designated to offset the exchange rate variation of debts, as
well as extraordinary effects, including tax expenses from dividends received abroad and inventory losses. In 2024, the set of Other Revenues
and Operating Expenses was negative by R$ 1,565 million, representing a reduction of 40.6% compared to 2023, reflecting the positive balance
of hedge operations. |

 | 4Q24 AND 2024 RESULTS |
| |
| · | In turn, the Financial Result
was negative by R$ 1,262 million in 4Q24, which represents a reduction of 34.6% in relation to the previous quarter and reflects the
drop in financial expenses due to the positive impact of the exchange rate variation on investments abroad. In the year, the Financial
Result was negative by R$ 5,814 million, an increase of 40.1% due to the impact of the increase in interest on financial expenses, as
well as the negative effect of the devaluation of Usiminas shares. |

| · | The Equity Result recorded
another good performance in 4Q24, reaching R$ 134 million, which corresponds to an increase of 8.9% compared to 3Q24, as a result of the
high performance that MRS has been able to achieve in recent quarters, in addition to the positive effect that the improved environment
in the steel industry has had on Panatlântica's results. In the year, the equity result was positive at R$ 448 million, which corresponds
to a growth of 27.7% when compared to 2023. |

| · | In the fourth quarter of 2024,
CSN recorded a net loss of R$ 85 million, an improvement of 88.7% on the previous quarter, reflecting the strong operating result
recorded in the period. This performance was offset by the still high volume of financial expenses and the higher incidence of taxes.
In 2024, the company recorded a net loss of R$ 1.5 billion, which contrasts with the net profit of R$ 402.6 million recorded in the previous
year and reflects the worsening commodity prices seen throughout 2024, as well as the increase in financial expenses. |

Adjusted EBITDA

*The Company discloses its adjusted EBITDA excluding the participation
in investments and other operating income (expenses) as it believes that they should not be considered in the calculation of recurring
operating cash generation.
| · | In 4Q24, Adjusted EBITDA
reached R$ 3,335.0 million, with an Adjusted EBITDA margin of 26.8% or 7.1 p.p. higher than in the previous quarter. This improved
performance is the result of a combination of higher realized prices in mining and cement, as well as a substantial improvement in the
steel segment. As a result, even in a seasonally weaker quarter and with a higher incidence of rainfall, it was possible to see EBITDA
46.0% higher than in 3Q24, also helping to highlight all the operational excellence that the company has been able to generate in recent
quarters. In the year, adjusted EBITDA reached R$ 10.2 billion, with an adjusted EBITDA margin of 22.4% or 2.9 p.p. below the previous
year as a consequence of the lower price of iron ore seen throughout the year, in addition to all the pressure that the increase in import
penetration brought to the steel segment in 2024. |
Adjusted EBITDA (R$ million) and
Adjusted EBITDA Margin (%)

¹ The Adjusted EBITDA Margin is calculated by
dividing Adjusted EBITDA by Adjusted Net Revenue, which takes into account CSN Mineração's 100% stake in consolidation
and 37.49% in MRS.

Adjusted Cash Flow
Adjusted Cash Flow in 4Q24 was negative at R$ 1,748.0
million, which represents a 77.3% worsening in relation to the previous quarter, even with the operational improvement seen in the period.
This result reflects the impact of financial expenses due to the exchange rate variations and the higher level of investments made, which
is typical for this time of the year.
4Q24 Adjusted Cash Flow¹ (R$ million)
¹ The concept of adjusted cash flow is calculated
from Adjusted EBITDA, subtracting EBITDA of Jointly Controlled Companies, CAPEX, Income Tax, Financial Result and changes in Assets and
Liabilities², excluding the effect of the Glencore advance.
² Adjusted Working Capital is made up of the
variation in Net Working Capital, plus the variation in long-term asset and liability accounts and disregarding the net variation in Income
Tax and Social Security.
Indebtedness
On 12/31/2024, consolidated net debt reached R$ 35,704
million, with the leverage indicator measured by the Net Debt/EBITDA LTM ratio reaching 3.49x, which represents an increase of 15 basis
points compared to the previous quarter. This higher indebtedness recorded in the period is a direct consequence of the impact of the
exchange rate variation on the dollar debt, which ended up offsetting not only the operational improvement in the quarter, but also all
the efforts made by the company to strengthen its cash flow through the sale of a significant stake in CSN Mineração. In
this sense, excluding the one-off effect of the exchange rate variation on the result, leverage in 4Q24 would have been 3.24x. Nevertheless,
CSN remains firm in its commitment to reduce leverage over the course of 2025 and the improvement in results recorded at the end of 2024
is an important indicator that the outlook remains stronger for the coming quarters. In addition, the company continues to make progress
on capital recycling projects within the group as an alternative way of injecting liquidity and reinforcing cash. Lastly, CSN maintained
its policy of carrying a high level of cash, which reached the record volume of R$ 24.9 billion this quarter.
¹Net
Debt / EBITDA: Debt is calculated using the final dollar of each period and net debt and EBITDA are calculated using the average dollar
of the period.

CSN continues to be very active in its goal of extending
its amortization period, with a focus on long-term operations. Among the main operations in 4Q24, the company raised funds and refinanced
some bilateral contracts with amortization flows between 2027 and 2029.
Amortization Schedule (R$ Million)

¹ IFRS: consider stake in MRS (37.49%).
² Gross Debt/Management Net Debt considers stake in MRS (37.49%),
without accrued interest.
3 Average time after completion of the Liability Management
Plan.
FX Exposure
The net foreign exchange exposure accumulated in
the 4Q24 consolidated balance sheet was US$ 1,073 million, as shown in the table below, in line with the company's policy of minimizing
the impact of exchange rate volatility on results. The Hedge Accounting adopted by CSN correlates the projected flow of exports in dollars
with future debt maturities in the same currency. As a result, the exchange rate variation of the dollar debt is temporarily recorded
in shareholders' equity and is taken to the income statement when the dollar revenues from these exports occur.

Investments
A total of R$ 2,058 million was invested on 4Q24,
which is 57.2% higher than in the previous quarter and 29.2% more than in the same period in 2023. This movement is a direct result of
progress in the infrastructure construction of P15 in mining and the improvements made in the melt shop, sintering and modernization of
operations at UPV. In addition, it is important to note that CSN traditionally concentrates its investments at the end of the year and
that the total invested in 2024 (R$ 5,527 million) was in line with the guidance projected for the year. Finally, it is worth noting that
investments in capacity expansion, such as those seen now in 4Q24, will be dominant over the coming quarters, replacing a lower need for
maintenance Capex.
CAPEX (R$ Million)

Net Working Capital
Net Working Capital applied to the business
was R$ 2,412 million in 4Q24, further advancing on the solid result recorded in the previous quarter, which reflects the increase in accounts
receivable due to the operational improvement and increase in the iron ore price, in addition to the reduction in the supplier line, given
the adjustment of the forfaiting lines.
The calculation of net working capital applied to
the business excludes the advance on prepayment contracts, as shown in the table below:

¹ Other NWC Assets: Considers
advances and other accounts receivable.
² Other NWC Liabilities:
Considers other accounts payable, dividends payable, taxes paid in installments and other provisions.
³ Inventories: Does not
take into account the effect of the provision for inventory losses. Warehouse stock balances are not taken into account when calculating
the SME.
Financial Operations
With the ongoing objective of extending the amortization
term and focusing on long-term operations and the local capital market, on November 5, 2024, the Company issued its 16th simple
debentures in the total amount of R$ 500 million, with the objective of investing in infrastructure.
In addition, one of its subsidiaries, Companhia Estadual
de Energia Elétrica - CEEE-G, issued on January 27, 2025, the 3rd issue of simple debentures in the total amount of
R$ 1.2 billion, also with the aim of investing in infrastructure.

Steel Results
According to the World Steel Association (WSA), global
crude steel production totaled 1,883.9 million tons (Mt) in 2024, a practically stable level compared to 2023, with production in India,
Turkey and Vietnam managing to offset a stronger slowdown seen in North American (-4.2%), Russian (-4.2%) and Asia and Oceania (-1.0%).
China, which accounted for 53.4% of total global
annual production, saw an 1.7% drop in production compared to 2023, but still maintained a high utilization rate of its blast furnaces.
On the other hand, this slowdown in domestic demand has caused concern on the part of the local government and encouraged new stimulus
packages, such as those announced at the end of September, in an attempt to regain momentum in the real estate sector. It can also be
seen that the drop in the pace of steel production in China is much less pronounced than had been feared and has been sustained by other
sectors of the economy, such as the automotive industry, industry in general and larger volumes destined for export.
At the other end of the spectrum, India, Turkey and
Brazil showed growth in production compared to last year, with volumes reaching 149.6 thousand tons (+6.3%), 36.9 thousand tons (+9.4%)
and 33.7 million tons (+5.3%), respectively.
Brazilian steel production continues to heat up,
driven by the operational normalization of local producers and greater steel consumption by sectors such as the automotive industry, the
yellow line (buses, trucks, etc.), agricultural machinery and infrastructure projects.
OPERATIONAL AND SALES PERFORMANCE
CSN's steel production is continuing its recovery
process and 2024 was the best year since 2022, reaching a level of 3,786 thousand tons produced, which represents growth of 14.9% compared
to last year. This growth comes shortly after the scheduled maintenance stoppages carried out in the sintering area of the Presidente
Vargas Plant (UPV), once again reinforcing normalization and efficiency with the resumption of work.
In 4Q24, CSN's Steel Production at UPV registered
963 thousand tons, a 3.2% lower performance compared to 3Q24, but in line with the seasonality of the period. In the annual comparison,
the fourth quarter of 2024 showed growth of 7.8%, underlining all the operational normalization.
Following the same trend of records for the year,
laminate production reached 3,474 thousand tons in 2024, the best figure since 2022, with a growth of 11.9% compared to the previous year.
Long steel production, on the other hand, recorded
its best marks since 2019 when production began by the CSN Group, reaching an annual production volume of 239 thousand tons and a quarterly
volume of 66 thousand tons, with a growth of 13.7% when compared to previous periods.

Sales Volume (Kton) - Steel Industry

Total sales in 4Q24 amounted to 1,175 thousand tons,
a small increase of 0.8% compared to the previous quarter, which demonstrates the strength of the company's commercial activity in overcoming
the negative seasonality of the period. When compared to the same period in 2023, sales increased by 10.4%, a performance in line with
the strong apparent consumption of the domestic market, which accounted for the sale of 876 thousand tons of steel products, representing
a massive annual growth of 15.0%. All this performance reinforces the assertive commercial strategy adopted by CSN, as well as the continued
upturn in industrial activity with higher steel consumption. In the foreign market, sales totaled 299 thousand tons in 4Q24, in line with
3Q24 and 1.1% below the same quarter of the previous year, with 2 thousand tons being exported directly and 297 thousand tons sold by
subsidiaries abroad, of which 66 thousand tons by LLC, 162 thousand tons by SWT and 69 thousand tons by Lusosider.
When looking at annual sales volume, 2024 stood out
as the best year for sales since 2022, totaling 4,551 thousand tons, a significant growth of 9.2% compared to 2023. This performance was
driven by the recovery of the domestic market, which recorded 3,273 thousand tons sold (+12.2%), in addition to the 2.4% growth in sales
to foreign markets. The advance in the foreign market was sustained by the increase in sales at international subsidiaries, with LLC reaching
311 thousand tons (+4.5%) and SWT totaling 652 thousand tons (+9.6%).
In
terms of total sales volume, the main highlight in 4Q24 was the Distribution segment, with a 2.1 p.p. increase compared to the volume
sold in the previous quarter, reaching 34.7% of total volume. In turn, the General Industry segment (16.2%) was the segment that lost
the most share of sales due to seasonality and greater commercial activity in the other segments. When comparing total sales volume in
4Q24 with 4Q23, the Construction segment fell by 2.3 p.p. to 18.8%, followed by Packaging, which fell by 1.3 p.p. to 7.8%. When comparing
2024 with 2023, there were significant recoveries in General Industry (2.1 p.p.) and Distribution (1.1 p.p.), but falls in the Auto (-0.3
p.p.) and Packaging (-2.3 p.p.) segments. |
|
According to ANFAVEA (the National Association of
Motor Vehicle Manufacturers), car production in 2024 reached 2,549 thousand units, up 9.7% on the previous year. This performance was
mainly driven by the production of heavy vehicles, which grew by 41.9% in production and 15.7% in sales.
Looking at data from the Brazil Steel Institute (IABr),
crude steel production in 2024 reached 33.7 Mton, a performance 5.3% higher than in 2023. Apparent Consumption was 25.9 Mton, an increase
of 8.3% year-on-year.

And the Steel Industry Confidence Indicator (ICIA)
for December was 50.1 points, still above the 50-point dividing line, reflecting solid confidence in the domestic market's prospects for
the coming months.
According to IBGE data, the production of household
appliances for the month of December 2024 registered an increase of 19.1% compared to the previous year, which reinforces the resumption
of the white goods sector after the weak performances seen in 2022 and 2023.
· | | Net Revenues
in Steel reached R$ 6,163 million in 4Q24, a performance 2.0% higher than in 3Q24 and 9.0% higher than in the same period
of the previous year, reflecting the strong commercial performance recorded in the period by managing to break the seasonality with volume
and price growth. In 2024, Net Revenue totaled R$ 23,179 million and was 2.0% higher than in 2023. |
· | | The average
price in 4Q24 reached R$ 4,988/ton, a reduction of 3.2% when compared to the previous quarter, with the foreign market being solely
responsible for the 14.2% drop in the average ticket for the period, with the worsening of the international market more than offsetting
the currency devaluation seen in the period. The performance of the average price on the domestic market grew by 0.8%, driven mainly
by the readjustments in long steel. In the year, the Average Price was R$ 4,987/ton, which represents a reduction of 6.8% when compared
to 2023, still reflecting the pressure of imported steel on the Brazilian market. |
· | | In turn, the Slab
Cost in 4Q24 reached R$3,510/ton, an increase of 4.3% compared to the previous quarter, reflecting the increase in the cost
of imported raw materials due to the strong currency devaluation recorded in the period. In 2024, the Slab Cost reached R$ 3,457/ton,
or a reduction of 9.1% compared to the previous year, reflecting a greater dilution of fixed costs and less pressure from raw material
prices. |
· | | Steelmaking's
Adjusted EBITDA reached R$ 656 million in 4Q24, 68.8% higher than in 3Q24, with an Adjusted EBITDA Margin of 10.6%, or
4.2 p.p. higher than in the previous quarter. In the year-on-year comparison, the increase is even more significant, with the EBITDA
margin expanding by 4.9 p.p.. This was the first time in the year that the segment's EBITDA margin reached double-digit profitability,
which reinforces the gradual recovery that the segment experienced throughout the year, with increased production, sales and lower expenses.
In 2024, the steel segment's Adjusted EBITDA reached R$ 1,603 million, with an Adjusted EBITDA Margin of 6.9%, which represents a reduction
of 1.1 p.p. compared to 2023. If we look at the outlook for 2025, we can see that this recovery in results continues with a favorable
trend, with steel consumption maintaining a positive pace, while it is already possible to see stronger price dynamics. |

Adjusted EBITDA and EBITDA Margin - Steel Industry

Mining Results
4Q24 was a period marked by a strong pace of iron
ore production despite the negative seasonality in Brazil, with the start of the rainy season. Shipments at Brazilian ports registered
the best quarterly result in the last 4 years, in addition to record shipments at some of the main Australian export terminals, accumulating
high volumes of port inventories in China. However, various economic stimulus measures made by the Chinese government have helped to keep
iron ore demand hot, resulting in an increase in capacity utilization at Chinese steel mills. In this scenario, iron ore had an average
price of US$ 103.4/dmt (Platts, Fe62%, N. China), 3.7% higher than the average for 3Q24 (US$ 99.7/dmt), but 9.3% lower than that recorded
in 4Q23 (US$ 128.30/dmt).
After the spikes in freight prices seen in 3Q24 (average
of US$ 26.67/t), the cost of the BCI-C3 (Tubarão-Qingdao) maritime route fell by 19% in 4Q24, registering an average of US$ 21.62/t.
This dynamic is in line with the lower volume of iron ore and bauxite shipped in the period and in line with the natural seasonality of
the rainy season in Brazil.

| |
· | | Iron Ore Production
(including purchases from third parties) reached a volume of 11,002 thousand tons in 4Q24, a decline of 3.8% compared to the third
quarter of 2024, but in line with the seasonal rainfall characteristic of the end of the year and with the volume recorded in 4Q23. When
looking at the year 2024, iron ore production (including purchases from third parties) was 41,997 thousand tons, meeting the guidance
published by the company and only 1.5% lower than in 2023, which reflects the strategy adopted throughout the year of prioritizing
margin over volume, with a lower volume of iron ore purchases from third parties. Overall, it can be said that 2024 was a very important
period in the Company's history, with several operational records in cargo handling and the highest volume of own production since 2019,
which demonstrates the solid efficiency of the operation and all the logistical excellence that CSN has been able to achieve. |
Sales Volume - Mining (thousand tons)

· | | Sales volume,
in turn, was 10,731 thousand tons in 4Q24, 9.7% below the volume recorded in the third quarter of 2024, which is in line with the
impact of the rains on the pace of production. Compared to 4Q23, there was also a 3.7% drop in the pace of sales, despite the increase
in shipments during the period, reflecting the lower volume recorded on the domestic market. In 2024, the sales volume was 42,552 thousand
tons, in line with 2023. Another important highlight in 2024 was the record number of tons shipped at TECAR terminal, which allowed the
company not to depend on third-party ports, helping to reduce logistics costs and maximize results. |
· | | Adjusted Net
Revenue totaled R$ 3,933 million in 4Q24, a performance 31.6% higher than that recorded in the third quarter of the year, as a exclusively
result of better price realization with the resumption of Platts and the positive effect of cargoes with exposure to future quotation
periods, helping to offset the reduction in volume. Unit Net Revenue was US$ 61.71 per ton in 4Q24, up 34.5% on the previous
quarter, as a result of the recovery in the iron ore average price and a lower demerit of the exported product. In 2024, Adjusted
Net Revenue totaled R$ 13,093 million, a performance 23.6% below that recorded in 2023, the sole result of the downward curve in
the iron ore price, despite the results presented throughout the year, with the growth in own production. |
· | | In turn, mining's
Cost of Goods Sold was R$ 2,193 million in 4Q24, an increase of 4.7% on the previous quarter, due to the higher
volume of purchases. C1 cost reached US$ 20.4/t in 4Q24, up 6.3% on the previous quarter, reflecting the lower dilution of fixed
costs due to the lower volume. In 2024, mining's Cost of Goods Sold totaled R$ 8,202 million, a performance 17.4% lower than that
recorded in 2023, as a result of the sharp reduction in the volume of purchases, which reflects the strategy of prioritizing unit margin. |
· | | Adjusted EBITDA
reached R$ 1,972 million in 4Q24, with a quarterly Adjusted EBITDA margin of 50.1%, representing strong growth of 12.6 p.p. over
the previous quarter. This greater profitability is the exclusive consequence of the recovery in prices, coupled with the solid operating
results achieved in the period. In 2024, adjusted EBITDA from mining was R$ 5.8 billion, with an adjusted EBITDA margin of 44.3%, which
represents a drop of 1.5 p.p. compared to the previous year even with a 9.3% drop in the iron ore average price, which demonstrates all
the operational excellence recorded in the period. |

Cement Results
According to the National Union of the Cement Industry
(SNIC), the real estate market continued to heat up in the second half of the year, even with all the pressures of high interest rates,
which shows a still poignant dynamism with new launches being announced, especially in the Minha Casa, Minha Vida segment . 2024 ended
with a cement sales volume 3.4% higher than the previous year, reaching 64.7 million tons and highlighting all the resilience that the
civil construction and infrastructure sectors have shown.
In 4Q24, sales volume fell by 3.9%, which is in line
with the seasonal nature of the period, with fewer working days and a higher incidence of rain. On the other hand, when we look at the
sales volume for 2024, we see a total of 13,524 thousand tons sold, which represents an increase of 5.9% on the previous year and
underscores the assertive strategy adopted to make the most of the logistics modal and distribution centers to enter new markets, gain
market share and capture synergy gains.

 | 4Q24 AND 2024 RESULTS |
| |
· | | Net Revenue
amounted to R$ 1,177 million in 4Q24, a decrease of 7.5% when compared to the previous quarter, which reflects the seasonality of
the end of the year with fewer working days and an increase in the incidence of rain. On the other hand, when compared to the same period
of last year, Revenue growth was 8.0%, with a stronger volume of sales observed in the period. In 2024, Net Revenue grew by 5.7% to R$
4,766 million, reflecting not only greater commercial activity, but also the entire strategy to advance in the chain of products with
greater added value. |
· | | Cement COGS
in 4Q24 was 11.1% lower than in the previous quarter, which is in line with the seasonality of commercial activity and optimization
of raw material costs. In the year to date, Cost of Goods Sold reached R$ 3,384 million, 7.1% down on the previous year, reflecting the
progress made in capturing synergies and the greater dilution of fixed costs. |
· | | As a result, Adjusted
EBITDA grew by 10.4% compared to the previous quarter, reaching R$ 386 million in 4Q24 and with an EBITDA margin of 32.8%, which
represents a new milestone for CSN's cement segment after the incorporation of the assets acquired in 2022 and reinforces not only the
efficiency of the operation, but also all the success with capturing synergies. In 2024, Adjusted EBITDA reached R$ 1,361 million, a
growth of 39.5% compared to 2023 and with an EBITDA Margin of 28.5%. The combination of an excellent commercial pace, cost control and
operational efficiency is what makes CSN a company that is increasingly well positioned in the cement market and ready to capture the
opportunities that still lie ahead in the Brazilian market. |
Energy Results
Net Revenue reached R$ 163 million in 4Q24,
up 7.9% on 3Q24, while Adjusted EBITDA was R$ 39 million, with an Adjusted EBITDA Margin of 24.1%. This performance reflects
a 16.0 p.p. reduction in profitability in the period due to higher costs earned in the operation as a result of the normalization of operational
activities after the weather event in Rio Grande do Sul. In 2024, Net Revenue was R$ 521 million, while Adjusted EBITDA reached R$ 143
million with an Adjusted EBITDA Margin of 27.4% in 2024, which represents growth of 1.1 p.p. in relation to the previous year even with
all the adversities seen in the period.
Logistics Results
In 4Q24, the Logistics segment was affected by lower
shipments in both rail and port due to the seasonality of the period. As a result, Total Net Revenue was R$ 758 million, which is 15.0%
down on the previous quarter. Adjusted EBITDA was R$ 305 million, a reduction of 28.9% when compared to 3Q24, and 12.9% against the previous
year. However, even with a 7.8 p.p. drop in the Adjusted EBITDA Margin, profitability remained at very high levels (40.3% in 4Q24). In
relation to 2024, the segment's performance was exceptional, with Adjusted EBITDA reaching R$ 1,527 million and an Adjusted EBITDA margin
of 47.1%, with the segment becoming increasingly representative on the consolidated result.
In the case of Railway Logistics, Net Revenue
reached R$ 668 million in 4Q24, with Adjusted EBITDA of R$ 278 million and an Adjusted EBITDA Margin of 40.9%. In comparison
with 3Q24, revenue fell by 15.8%, with Adjusted EBITDA 28.8% lower.
In Port Logistics, Sepetiba Tecon shipped
1,308 thousand tons of steel products in 2024, as well as 135 thousand containers, 58 thousand tons of general cargo and 658 thousand
tons of bulk cargo. In comparison with the same period in the previous year, the company increased its shipments and, as a result, Net
Revenue from the port segment was 35.4% higher, reaching R$ 353 million. Adjusted EBITDA was also positively impacted, reaching
R$ 130 million in 2024, with an Adjusted EBITDA Margin of 36.9%, or 16.5 p.p. higher than in 2023.

ESG – Environmental, Social & Governance
ESG PERFOMANCE –CSN GROUP
Since the beginning of 2023, CSN has adopted
a new format for disclosing its ESG actions and performance, making its performance in ESG indicators available on an individualized basis.
The new model allows stakeholders to have quarterly access to key results and indicators and to monitor them in an effective and even
more agile way. Access can be made through the results center of CSN's IR website: https://ri.csn.com.br/informacoes-financeiras/central-de-resultados/.
The information included in this release has
been selected based on its relevance and materiality to the company. Quantitative indicators are presented in comparison with the period
that best represents the metric for monitoring them. Thus, some are compared with the same quarter of the previous year, and others with
the average of the previous period, ensuring a comparison based on seasonality and periodicity. In addition, it is important to highlight
that the ESG Performance Report also incorporates the performance indicators of CSN Cimentos' new assets, acquired in 2022, so that some
absolute indicators will undergo significant changes when compared to the previous period.
More detailed historical data on CSN's performance
and initiatives can be found in the 2023 Integrated Report, released in May 2024 (https://esg.csn.com.br/nossa-empresa/relatorio-integrado-gri).
The review of ESG indicators occurs annually for the closing of the Integrated Report, so the information contained in the quarterly releases
is subject to adjustments resulting from this process.
It is also possible to monitor CSN's ESG performance
in an agile and transparent manner, on our website, through the following electronic address: https://esg.csn.com.br.
