<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">Gerdau S.A. (the &ldquo;Company&rdquo;
or &ldquo;we&rdquo;) evaluated the current product lines of its consolidated group and determined that it manufactures products which
contain metals derived from minerals defined as &ldquo;Conflict Minerals,&rdquo; which include tantalum, tin, tungsten and gold. Tungsten
is used by us in the production of some special steel bars that we produce in Brazil.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">The Company conducted a reasonable
country of origin inquiry based on the OECD Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and
High-Risk Areas (Second Edition, OECD 2012) reasonably designed to determine whether any of the conflict minerals we use originated in
the Democratic Republic of the Congo or an adjoining country. We requested and received written responses from each of our suppliers (smelters,
refiners and distributors, as the case may be) of tungsten using the format of the questionnaire template developed by the Electronic
Industry Citizenship Coalition and Global e-Sustainability Initiative. We do not purchase raw ore or unrefined conflict minerals and we
make no direct purchases in the Democratic Republic of Congo or adjoining countries as defined in the instructions to Form&nbsp;SD (collectively,
&ldquo;Covered Countries&rdquo;).</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">The Company&rsquo;s ability
to make reliable determinations about the source of Conflict Minerals in its products depends upon various factors, including, but not
limited to, (i)&nbsp;the respective due diligence efforts of its direct suppliers and their supply chain, together with their willingness
to provide the requested information, representations and certifications to the Company, and (ii)&nbsp;the ability of the entities involved
in the Company&rsquo;s supply chain to make determinations consistent with nationally or internationally recognized standards, including
the OECD Guidance.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">Based on the written responses
received to our reasonable country of origin inquiry and, as appropriate, other communications with our suppliers, which in each case
we consider reliable, we have concluded that the tungsten we purchase through our supply chain does not come from the Covered Countries.
