or &ldquo;Gerdau&rdquo;) announces an investment plan in Minas Gerais amounting to R$6 billion over the next five years, which includes
modernization, technological updating and expansion projects at its sites in the state. The investment, which reinforces the company&rsquo;s
commitment to the state&rsquo;s sustainable, economic and social development, will create over 6,000 new direct and indirect jobs.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">The investments are divided into three fronts:
growth, technological updating and diversification, with improving environmental practices a basic principle incorporated across all projects.
The plan, which involves all regions where Gerdau has operations, will benefit dozens of municipalities in the state of Minas Gerais and
focus on steel production, mining, renewable energy generation and forest cultivation.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">Two important investments to expand steel production
will be made in Ouro Branco, where the company&rsquo;s main production unit is located. The unit&rsquo;s annual production capacity of
hot-rolled coils will expand by 250,000 tons/year, with commercial startup slated for early 2024. Gerdau also is expanding the production
of structural profiles by 500,000 tons/year, which represents a doubling of current capacity, with startup estimated for 2025. The expansion
projects are part of Gerdau&rsquo;s mission of continuing to meet the growing demand from the sectors that consume these products in Brazil
and Latin America.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">&ldquo;The new production capacity of hot-rolled
coils will enable us to continue delivering steel products with higher added value to our clients. Meanwhile, the production expansion
in structural profiles, a segment that we have pioneered in Brazil since 2000, is aligned with our strategy to develop the metallic construction
segment, which will leverage productivity in the building, industrial and infrastructure sectors,&rdquo; said Marcos Faraco, vice-president
at Gerdau.</P>

includes not only the Ouro Branco Unit, but also its plants located in the municipalities of Bar&atilde;o de Cocais, Divin&oacute;polis

its base of renewable eucalyptus forests, expanding them by 20% to support the production of charcoal, a so-called bioreducer used in
steel production to substitute fossil-based coal. Gerdau already has a forest base in Minas Gerais that includes eucalyptus plantations
and preservation areas covering 250,000 hectares in dozens of municipalities, which enables its steel production operations to register

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">Another investment in the plan to improve the
sustainability and diversification of Gerdau's business involves developing a photovoltaic complex in the municipality of Brasil&acirc;ndia
de Minas, located in northern Minas Gerais state. Gerdau and Shell Brasil signed a cooperation agreement that establishes the basic principles
for negotiating and creating a joint venture. With installed capacity of 190MWdc, the Aquarii Complex will supply a portion of its clean
energy to Gerdau's steel mills, while the balance will be sold on the free market through Shell's energy trading arm, starting as from
2024.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">&ldquo;We began our long history of trust and
partnership with Minas Gerais 32 years ago, and since then have always worked to ensure sustainable and integrated operations across the
state. This new investment plan represents an important advance in our long-term strategy, which sees in Gerdau's long and flat steel
production units in Minas Gerais a large growth platform for the coming years,&rdquo; concluded Faraco.</P>
