Four decades of Latin American conglomerate compounding, on one filterable page.
Carlos Slim Helú (b. 1940, Mexico City) built the largest business empire in Latin America across four decades by acquiring struggling Mexican industrials in the 1980s, seizing the transformative 1990 Telmex privatization for approximately $1.76 billion, and then rolling that platform up into América Móvil — the dominant mobile telecom operator across most of Latin America under the Claro brand. The empire sits on a three-entity architecture: Grupo Carso (industrial, retail, real estate), América Móvil (telecom), and Grupo Financiero Inbursa (banking, insurance, asset management). US positions have included TracFone Wireless (sold to Verizon 2021 for ~$6.9B), Saks Fifth Avenue, and up to a 17% stake in The New York Times Company. Family control runs through six children — Carlos Slim Domit chairs América Móvil and Telmex, Marco Antonio Slim Domit chairs Grupo Financiero Inbursa, and Patrick Slim Domit holds director positions across the group. This page catalogs the material record. It is intentionally a living reference: as new deals close or divestitures are announced, the row is added, the roll-ups reflow, and the sitemap timestamp bumps. Nothing here is investment advice. Everything here is a fact-checkable practitioner reference for a very specific question — what does four decades of Latin American conglomerate compounding actually look like in list form?
Nine columns. Year of announcement or close. Target name. Region at time of acquisition (Mexico, Colombia, Brazil, Argentina, Chile, Peru, Ecuador, Central America, Caribbean, US, Netherlands, Austria, or Corporate for family-office holdings). Approximate consideration in USD (illustrative where deal size was not publicly disclosed — marked "n/d" for not-disclosed or "approx"). Deal structure — the Slim signature is disciplined negotiated acquisitions in privatizations, distressed situations, and family-owned company transitions. Counterparty type. The family-controlled compounder flag — was the target retained under Slim-family voting control as a long-term compounder holding within the three-entity structure? Distinctive notes. Current status — held, divested, or consolidated into América Móvil, Grupo Carso, or Inbursa.

Three-entity structure. The Slim empire is not one holding company — it is three. Grupo Carso, S.A.B. de C.V. (BMV: GCARSO) is the industrial and retail holding (Sanborns, Sears Mexico, CICSA construction, Condumex cables, mining stakes). América Móvil, S.A.B. de C.V. (BMV: AMX, NYSE: AMX) is the telecom champion — Telmex fixed-line was folded back in through the 2010s. Grupo Financiero Inbursa, S.A.B. de C.V. (BMV: GFINBURO) is banking, insurance, brokerage, and asset management. Every row on this page is tagged to a home entity in the notes column so readers can trace which subsidiary a given acquisition landed in.
Family-controlled compounder marker. A YES flag means the target was retained under Slim-family voting control as a long-term compounder holding — the signature Slim pattern of buying assets cheap in distressed or privatization moments and holding for multi-decade returns. A NO flag means the transaction was a divestiture, a portfolio-level minority position later sold, or a financial-services investment made through Inbursa rather than an operating holding. The family-compounder pattern applied to approximately 85 percent of the material transactions on this page — the pattern is not incidental to the compounding record; it is the record. Slim rarely sells the crown jewels. Telmex, Carso, Inbursa, Sanborns have all been under Slim-family control since acquisition. Even TracFone — ultimately sold to Verizon in 2021 — had been held for thirteen years.
Every material Carlos Slim acquisition since the 1981 Cigatam / Cigarrera La Moderna deal, spanning Grupo Carso industrial, América Móvil telecom, and Grupo Financiero Inbursa financial services, on one page. Sortable by year, region, deal size, structure, and counterparty type — with the family-controlled compounder flag applied across four decades. Search by target name (Telmex, Telcel, América Móvil, Claro, Comcel, BSE Brasil, Techtel, Verizon Dominicana, TracFone Wireless, Sanborns, Sears Mexico, Condumex, CICSA, Frisco, Inbursa, Saks Fifth Avenue, The New York Times, KPN, Telekom Austria), by region (Mexico, Colombia, Brazil, Argentina, Chile, Peru, Ecuador, Central America, Caribbean, US, Netherlands, Austria), or by structure (privatization, take-private, controlling stake, subsidiary bolt-on). Every row is a fact-checkable reference. This is a living dataset — updated whenever the Slim entities close a new deal or announce a material divestiture.

Roll-ups reflect the acquisitions cataloged in the table above. Where consideration is undisclosed, the deal is included in count-based roll-ups but excluded from dollar-based totals. Dollar figures are illustrative aggregates — the point is directional, not audit-grade. Older 1980s Mexican transactions have thin public disclosure; several are directional entries. The 1990 Telmex privatization and the 2000s América Móvil pan-Latin American consolidation dominate the aggregate capital deployment.
Whole-company, privatization, controlling-stake, and take-private transactions only; minority stakes and divestitures excluded from the dollar totals. Bar length is proportional within this table only. The 1990s and 2000s are dominated by Telmex and the América Móvil pan-LatAm buildout; older 1980s figures are heavily approximated.
Negotiated whole-company acquisitions and controlling-stake purchases are the backbone of the record. The 1990 Telmex deal is the anchor privatization; a small handful of divestitures cluster in the 2010s and 2020s (KPN 2013, TracFone 2021, portions of the NYT position).
Region is captured at time of the transaction. Mexico dominates the pre-2000 record; the 2001-2015 América Móvil pan-Latin American expansion spread the geographic footprint across Colombia, Brazil, Argentina, Central America, and the Andean markets. US positions are almost entirely 2008-and-later.
The signature Slim pattern — buy cheap in distressed or privatization moments, retain under family voting control, hold for multi-decade compounding. Approximately 85 percent of the material transactions on this record are family-compounder holds. Divestitures are the exception rather than the rule; when they occur (TracFone to Verizon 2021, KPN 2013, portions of the NYT stake) they are typically completed at material profits after long holds.
An acquisition record is a lagging indicator. The leading indicator, for the Slim portfolio specifically, is the next-generation transition. Carlos Slim Helú is 86. His six children hold the operating and board-level roles across the three-entity structure: Carlos Slim Domit (chairman, América Móvil and Telmex), Marco Antonio Slim Domit (chairman, Grupo Financiero Inbursa), Patrick Slim Domit (director positions across Grupo Carso and América Móvil), plus Soumaya, Vanessa, and Johanna Slim Domit in philanthropic, artistic, and cultural roles including at the Museo Soumaya. The next decade is a stress test of whether the disciplined-acquirer playbook survives its architect.
The three entities are in different competitive phases. América Móvil remains the flagship — still the dominant mobile operator in Mexico and most of Latin America, but now defending market share against Telefonica-successor entities, Millicom, and various local challengers, and adjusting to regulatory pressure in Mexico (IFT concentration limits). Grupo Carso is compounding on the industrial and real-estate side, with the IDEAL infrastructure vehicle carrying most of the newer real-asset investment. Grupo Financiero Inbursa continues to run as one of Mexico's more disciplined universal banks with a distinctive corporate-lending orientation.
Post-Verizon TracFone divestiture, América Móvil has continued Latin American spectrum acquisitions and 5G rollout capex. Mexico regulatory concentration limits remain a strategic constraint; competitive pressure from AT&T Mexico and Telefonica-successor entities is a persistent theme.
The IDEAL (Impulsora del Desarrollo y el Empleo en América Latina) infrastructure vehicle houses the Slim group's toll-road, water, energy, and real-asset investments. Continued expansion in Latin American infrastructure concessions is the primary capital-allocation channel for the industrial-side portfolio.
Inbursa retains its distinctive corporate-lending orientation among Mexican universal banks — large-borrower concentration relative to Banorte, Santander Mexico, and BBVA Mexico. Insurance and pension-fund operations round out the platform.
Carlos Slim Helú's six children hold the operating and board-level roles: Carlos Slim Domit (AMX / Telmex chairman), Marco Antonio Slim Domit (Inbursa chairman), Patrick Slim Domit (director roles), plus Soumaya, Vanessa, and Johanna. The family control structure is designed for multi-generational continuity in the same pattern as Arnault (LVMH) and Walton (Walmart).
The Slim record belongs to the small handful that define the modern family-controlled compounding era. These are the companion practitioner references already published on the Institute site.

The Baratelli Institute publishes under the Lowe v. SEC publisher exception; neutral positioning maintained throughout. Deal figures cited in this catalog are sourced primarily to Grupo Carso, América Móvil, and Telmex annual reports and Bolsa Mexicana de Valores filings, US SEC filings for the US-listed entities (America Movil ADR, TracFone Wireless disclosures via Verizon 8-K, NYT 13G filings), contemporaneous press coverage (Wall Street Journal, Financial Times, Reuters, Bloomberg, The New York Times, El Financiero, Reforma, Expansión, Milenio, América Economía), and standard reference works on the Slim history. Dollar amounts are approximate; where original consideration was denominated in MXN, BRL, ARS, COP, or CLP the USD equivalent is directional and reflects the transaction-date exchange rate. Where a specific transaction date or dollar figure is not publicly disclosed — a common condition for the 1980s Mexican industrial bolt-ons, the pre-privatization consortium arrangements, and various regional telecom transactions — the row is flagged with "approx" or "n/d" (not disclosed) in the notes column rather than fabricating precision.
