About Sergio

Seasoned executive and investment banker with 20 years spanning senior C-suite leadership (Interim CEO, CFO,
CSO) and elite M&A advisory (Lazard, G5 Partners) — an unusually complete perspective on strategy, capital
allocation and operational transformation.

Exceptional stakeholder communicator: built productive relationships with boards, CEOs, regulators (BACEN),
lenders and advisors across Brazil and 20 countries. Now seeking a senior executive mandate — CEO, CFO or
CSO — where strategic, financial and operational depth can drive transformational value creation.

    January 2023 - September 2023 (8 months)
    São Paulo, State of São Paulo, Brazil
    – Transitioned to Ame Digital by shareholder mandate as CFO/CSO — with a path to CEO — to reposition it as Americanas' flagship fintech, modeled on the Mercado Pago / Mercado Livre dynamic: a high-growth, standalone financial services business embedded in the Americanas ecosystem.
    – Americanas' Chapter 11 filing interrupted this repositioning mandate, requiring an immediate pivot: from strategic growth planning to making Ame financially viable as a fully standalone entity over a 24–36 month horizon.
    – Elevated to Interim CEO: redefined the business model — prioritised and discontinued units by contribution margin, growth potential and funding requirements; identified and launched new revenue streams; designed a talent retention plan.
    – Operational Turnaround: c. 50% workforce reduction; delivered positive net income and positive operating cash flows within the year.
    – Finance Architecture: designed ALM, transitioned from IFRS to Central Bank accounting standards, built a new FP&A function, launched a Business Intelligence unit, restructured treasury and compliance.
    – Regulatory: led constructive dialogue with BACEN throughout Chapter 11 for renewal of SCFI, IP and SEP fintech licences.

    RETAIL (LARGE RETAILERS)
    March 2021 - January 2023 (1 year and 10 months)
    São Paulo, State of São Paulo, Brazil
    Brazil's leading omnichannel retail and e-commerce ecosystem (~USD 10bn market cap). – Reported directly to the CEOs with a dotted line to the Chairman; managed a team of 10 across M&A, strategy and innovation. Designed and led the Group's external growth strategy — structured as a strategic investment holding that deployed capital raised on public markets (equity follow-ons, bond issuances) to build a diversified portfolio of adjacent businesses.
    – Built the corporate development function end-to-end: team, investment thesis, origination processes, due diligence frameworks, execution playbooks, post-acquisition synergy tracking and portfolio monitoring. Established advisory board-like governance structures for key portfolio companies, responsible for overseeing business evolution, synergy extraction and strategic milestones.
    – Investment philosophy: acquire without integrating — each portfolio company retained its entrepreneurial DNA, talent, brands and capabilities, while benefiting from the Americanas ecosystem (customer base, data, distribution, liquidity). Strategic objective: build Ame Digital as Americanas' financial services arm, replicating the Mercado Pago / Mercado Livre model.
    – Landmark corporate transaction: USD 10bn merger of Lojas Americanas with B2W, creating Americanas S.A., Brazil's leading omnichannel retailer (Jun. 2021). Portfolio: 15+ investments executed across Retail (Hortifruti, USD 500m), Fintech (Nexoos, Bit Capital), Consumer (Grupo Uni.Co), Technology (Skoob) and Energy (Vem JV with Vibra Energia).
