<P STYLE="color: #595959; font: 10pt Vale Sans,sans-serif; margin: 0; text-align: justify; text-indent: 0in">In response to the Official
Letter referenced above, attached to this reply, Vale S.A. (&ldquo;Vale&rdquo; or the &ldquo;Company&rdquo;) hereby provides the following
clarifications regarding the news article published on the Valor Econ&ocirc;mico newspaper&rsquo;s website on October 31, 2025, titled
&ldquo;It is likely we will pay extraordinary dividends soon, says Vale&rsquo;s management&rdquo;, which contains the following information:</P>

<P STYLE="color: #595959; font: 10pt Vale Sans,sans-serif; margin: 0; text-align: justify; text-indent: 0in">&nbsp;</P>

<P STYLE="color: #595959; font: 10pt Vale Sans,sans-serif; margin: 0 0 0 35.4pt; text-align: justify; text-indent: 0in">&ldquo;<B>It is

<P STYLE="color: #595959; font: 10pt Vale Sans,sans-serif; margin: 0 0 0 35.4pt; text-align: justify; text-indent: 0in">Market stability
creates conditions to consider extraordinary dividends, says Vale&rsquo;s Executive Vice President of Finance, Marcelo Bacci</P>

<P STYLE="color: #595959; font: 10pt Vale Sans,sans-serif; margin: 0 0 0 35.4pt; text-align: justify; text-indent: 0in">Marcelo Bacci,
Vale&rsquo;s Executive Vice President of Finance, stated this Friday (31) that it is likely the company will announce the payment of extraordinary
dividends &lsquo;soon.&rsquo;</P>

<P STYLE="color: #595959; font: 10pt Vale Sans,sans-serif; margin: 0 0 0 35.4pt; text-align: justify; text-indent: 0in">&lsquo;We cannot
anticipate the decision right now, because there are still things we need to [know], but it is likely that we will announce extraordinary
dividends soon,&rsquo; said Bacci during a conference call with analysts regarding the third quarter results.</P>

<P STYLE="color: #595959; font: 10pt Vale Sans,sans-serif; margin: 0 0 0 35.4pt; text-align: justify; text-indent: 0in">According to the
executive, market stability creates conditions to consider extraordinary dividends, and the company&rsquo;s cash flow is performing better
than expected.</P>

<P STYLE="color: #595959; font: 10pt Vale Sans,sans-serif; margin: 0 0 0 35.4pt; text-align: justify; text-indent: 0in">Company monitors
possible changes in dividend regulation</P>

<P STYLE="color: #595959; font: 10pt Vale Sans,sans-serif; margin: 0 0 0 35.4pt; text-align: justify; text-indent: 0in">Also during the
conference call, Marcelo Bacci stated that the company is monitoring possible changes in dividend regulation. He made the comment in response
to a question about potential changes in taxation. Currently, Bill No. 1,087/25 is being processed in the Senate, after being approved
by the House of Representatives.</P>

<P STYLE="color: #595959; font: 10pt Vale Sans,sans-serif; margin: 0 0 0 35.4pt; text-align: justify; text-indent: 0in">Regarding dividends,
Bill No. 1,087/25 proposes a 10% Withholding Income Tax (IRRF) on amounts exceeding R$50,000 per month per beneficiary, regardless of
the number of payments made during the month.</P>

<P STYLE="color: #595959; font: 10pt Vale Sans,sans-serif; margin: 0 0 0 35.4pt; text-align: justify; text-indent: 0in">Bacci emphasized
that the immediate impact on the company, should the bill be approved and come into effect, should be &lsquo;minimal.&rsquo; The executive
explained that the company&rsquo;s dividend policy provides for payments via interest on equity (JCP), which reduces the impact.&rdquo;</P>

<P STYLE="color: #595959; font: 10pt Vale Sans,sans-serif; margin: 0; text-align: justify; text-indent: 0in">&nbsp;</P>

<P STYLE="color: #595959; font: 10pt Vale Sans,sans-serif; margin: 0; text-align: justify; text-indent: 0in">Initially, we emphasize that
the changes proposed by the Draft Law No. 1,087/25 (<I>Projeto de Lei &ndash; PL n&deg; 1.087/25</I>) are public, and not only Vale but
also other companies have been monitoring the matter and discussing its impacts, as well as possible alternatives. In this context, it
is natural for the Company&rsquo;s management to consider a possible extraordinary distribution of dividends in light of the potential
effects of changes in the rules regarding dividend taxation.</P>

<P STYLE="color: #595959; font: 10pt Vale Sans,sans-serif; margin: 0; text-align: justify; text-indent: 0in">Furthermore, we clarify that
Vale has historically approved the distribution of dividends in the last months of each year, provided that the results recorded during
the year allow for such distribution. For example, in the fiscal years of 2024, 2023, and 2022, dividend distributions were approved in
the months of November, October, and December, respectively.</P>

<P STYLE="color: #595959; font: 10pt Vale Sans,sans-serif; margin: 0; text-align: justify; text-indent: 0in">&nbsp;</P>

<P STYLE="color: #595959; font: 10pt Vale Sans,sans-serif; margin: 0; text-align: justify; text-indent: 0in">In this context, the statement
made by the Executive Vice President of Finance and Investor Relations merely aimed to clarify that, considering the proposed changes
in dividend taxation and the Company&rsquo;s results for the period, it is expected that the Company will approve the distribution of
extraordinary dividends in the near future. This would be in line with Vale&rsquo;s recent history and, therefore, anticipated by the
market. This is evidenced by the absence of any atypical oscillation in the price of the Company&rsquo;s common shares (VALE3), considering
the opening and closing prices on October 31, 2025, the date of the earnings conference.</P>

<P STYLE="color: #595959; font: 10pt Vale Sans,sans-serif; margin: 0; text-align: justify; text-indent: 0in">&nbsp;</P>

<P STYLE="color: #595959; font: 10pt Vale Sans,sans-serif; margin: 0; text-align: justify; text-indent: 0in">It should also be noted that
the reference to &ldquo;extraordinary&rdquo; dividends relates to the fact that Vale has already distributed, in the current fiscal year,
the minimum shareholder remuneration amount provided for in its Shareholder Remuneration Policy, which was fulfilled with the interest
on equity payment approved on July 31 and paid on September 4, 2025.</P>

<P STYLE="color: #595959; font: 10pt Vale Sans,sans-serif; margin: 0; text-align: justify; text-indent: 0in">&nbsp;</P>

<P STYLE="color: #595959; font: 10pt Vale Sans,sans-serif; margin: 0; text-align: justify; text-indent: 0in">It is worth recalling that
the possibility of the Company distributing extraordinary dividends during the second half of the year was highlighted during the presentation
of the Company&rsquo;s second quarter 2025 results, when it was clarified that, should iron ore prices remain within the observed range
at the time, there could be opportunity for additional payments to shareholders.</P>

<P STYLE="color: #595959; font: 10pt Vale Sans,sans-serif; margin: 0; text-align: justify; text-indent: 0in">&nbsp;</P>

<P STYLE="color: #595959; font: 10pt Vale Sans,sans-serif; margin: 0; text-align: justify; text-indent: 0in">Nonetheless, we clarify that
any potential distribution of extraordinary dividends would be subject to the necessary approvals in accordance with the Company&rsquo;s
governance procedures. For this reason, during the earnings conference, the CFO made it clear that it would not be possible to anticipate
any decision on the matter. In fact, there is no decision by the Company&rsquo;s Board of Directors regarding the potential declaration
of extraordinary dividends, the amount to be paid, or the payment date. Therefore, there is no requirement to disclose a Material Fact,
as per item XVI, Sole Paragraph of Article 2 of CVM Resolution No. 44/2021.</P>

Vale management,&quot; containing the following information:</FONT></TD></TR></TABLE>

Market stability creates conditions to consider extraordinary dividends, says Vale&rsquo;s Executive Vice President of Finance, Marcelo
Bacci</P>

<P STYLE="color: #595959; font: 10pt Vale Sans,sans-serif; margin: 0 0 0 19.5pt; text-align: justify; text-indent: -0.5pt">Vale&rsquo;s
Executive Vice President of Finance, Marcelo Bacci, stated this Friday (31) that it is likely the company will announce &ldquo;soon&rdquo;
the payment of extraordinary dividends. &ldquo;We cannot anticipate the decision now, because there are more things we need [to know],
but it is likely that we will have extraordinary dividends announced soon,&rdquo; said Bacci, in a conference call with analysts about
the third quarter results. According to the executive, market stability creates conditions for considering extraordinary dividends, and
the company&rsquo;s cash flow is performing better than expected.</P>

<P STYLE="color: #595959; font: 10pt Vale Sans,sans-serif; margin: 0 0 0 19.5pt; text-align: justify; text-indent: -0.5pt">The company
is monitoring possible changes in dividend regulation. Also during the conference call, Marcelo Bacci stated that the company is monitoring
possible changes in dividend regulation. He made the comment in response to a question about possible changes in taxation. Currently,
Bill 1,087/25 is being processed in the Senate, after being approved by the House of Representatives. Regarding dividends, Bill 1,087/25
provides for a 10% Withholding Income Tax (IRRF) on amounts above R$ 50,000 per month per beneficiary, regardless of the number of payments
in the month. Bacci emphasized that the immediate impact for the company, should the matter be approved and come into effect, should be
&ldquo;minimal.&rdquo; The executive explained that the mining company&rsquo;s dividend policy provides for payment via interest on equity
(JCP), which reduces the impact.</P>
