Claro to acquire Desktop S.A. for R$4bn as Claro NXT bets on fiber dominance in Sao Paulo

Claro Telecom Participacoes S.A., the Brazilian operating subsidiary of Mexican telecom giant America Movil (BMV: AMX; NYSE: AMX), has signed a definitive agreement to acquire a 73.01% controlling stake in Desktop S.A. (B3: DESK3), one of Sao Paulo state’s largest independent fiber internet service providers. The transaction values Desktop at R$4.0 billion enterprise value, or approximately $753 million, with the equity consideration landing at R$2.41 billion after netting out R$1.58 billion in debt as of September 2025, implying a per-share price of R$20.82. The deal marks a decisive chapter in Brazil’s ongoing fiber consolidation and positions Claro to meaningfully close the gap with Telefonica Brasil’s Vivo, the incumbent leader in the state of Sao Paulo. H.I.G. Capital, the Miami-based alternative investment manager with $74 billion in assets under management, is the vendor, exiting an investment that took Desktop from roughly 150,000 subscribers to over 1.2 million across more than 200 cities.

Why is Claro acquiring Desktop S.A. and what does this mean for Claro’s fiber broadband strategy in Brazil?

The strategic logic is straightforward and the market pressure behind it substantial. Claro is the leading broadband operator in Brazil by total subscriber count, holding roughly 20% of the overall fixed broadband market. But when the comparison narrows to pure fiber-optic infrastructure, the picture changes. Claro’s fiber-only market share sits at approximately 6.6%, against Vivo’s 15% and even Desktop’s 3%, according to data cited by BTG Pactual in its analysis of the transaction. That gap matters because hybrid fiber-coaxial networks, which still form a significant portion of Claro’s infrastructure base, are broadly considered a generation behind pure fiber in terms of speed, reliability, and upgrade potential.

Desktop’s footprint is precisely the kind of pure-fiber asset Claro cannot quickly replicate organically. The company’s network spans over 58,000 kilometers across the state of Sao Paulo, passing approximately 4.8 million homes in more than 200 cities, with the vast majority concentrated in interior Sao Paulo rather than the capital. Claro holds a 28% share in Sao Paulo state, but Vivo dominates at 31% overall and 42% in fiber-only terms. In the 198 cities where Desktop operates, the combined entity is expected to emerge as the market leader, making this acquisition as much about geography as about subscriber count.

How does the Claro and Desktop fiber deal reshape competitive dynamics against Vivo and regional ISPs in Brazil?

The competitive consequences extend well beyond the Claro-Vivo rivalry. Brazil’s broadband sector has been undergoing rapid consolidation driven by the proliferation of small and mid-size fiber ISPs, many of which were built on private equity capital during the infrastructure investment wave of the early 2020s. Desktop was the most prominent publicly listed example, having completed Brazil’s first ISP initial public offering on the B3 exchange in February 2021 under H.I.G.’s stewardship. Its acquisition by a large integrated operator signals that the consolidation cycle is moving from small regional players into the tier just below national scale, a shift that will likely accelerate M&A interest in other mid-size ISPs across Brazil.

Vivo, for its part, had its own opportunity to make this move. Telefonica Brasil was reported to have been in negotiations to acquire Desktop as recently as 2024, with those discussions ultimately stalling over concerns about network overlap. That decision now looks costly in competitive terms, as Claro’s successful acquisition hands the rival operator a ready-made fiber scale advantage in Sao Paulo interior markets where Vivo was already facing insurgent pressure from regional ISPs. The window for Vivo to respond with a comparable fiber-native acquisition in Sao Paulo has narrowed considerably.

What are the regulatory hurdles facing the Claro acquisition of Desktop and when is the deal likely to close?

The transaction is subject to approval from two Brazilian regulatory bodies: the Conselho Administrativo de Defesa Economica, Brazil’s competition authority, and the Agencia Nacional de Telecomunicacoes, the sector regulator. A shareholder extraordinary general meeting at Desktop will also be required. The deal has historically attracted regulatory scrutiny in Brazil’s telecom sector, given the concentration dynamics involved, but the relatively distinct geographic footprint of Desktop in interior Sao Paulo, combined with the continued presence of Vivo and numerous regional competitors in those markets, should reduce the likelihood of a protracted antitrust review.

Once the acquisition closes, Claro will be required to file an offer for the remaining publicly traded shares through a mandatory tender offer, or OPA under Brazilian capital markets rules, triggered by the change of control. Minority shareholders holding the 26.99% of Desktop not covered by the initial transaction will be entitled to sell at a price no lower than the R$20.82 per share paid to H.I.G. and the other controlling shareholders. This process effectively sets the stage for Desktop’s full delisting from the B3, which has become a recurring pattern as private equity-backed ISPs move from public markets back into integrated operator ownership.

How did H.I.G. Capital build Desktop into a fiber platform worth R$4 billion from its initial investment?

H.I.G. Capital’s exit crystallises what has been a well-executed private equity value-creation thesis in a high-growth emerging market sector. When H.I.G. acquired Desktop, the company served approximately 150,000 subscribers. By the end of 2025, that figure had grown to over 1.2 million, an increase of roughly 700%, delivered through a combination of organic network expansion and ten strategic acquisitions. The subscriber base growth was matched by geographic expansion from a narrow initial footprint to coverage of more than 200 cities across Sao Paulo state, supported by a fiber network that grew to over 58,000 kilometers.

H.I.G. also backed Desktop’s 2021 initial public offering on the B3, positioning it as the first publicly listed ISP in Brazil and providing a liquidity pathway and valuation benchmark that ultimately supported the current exit. Fernando Marques Oliveira, H.I.G.’s Managing Director and Head of Latin America, described the result as demonstrating the firm’s hands-on growth acceleration approach. The transaction delivers a strong financial outcome for H.I.G. investors and underlines the appetite among global alternative asset managers for Brazil’s digital infrastructure build-out, even as macroeconomic volatility, currency risk, and regulatory complexity remain persistent features of the operating environment.

What does the Desktop acquisition signal about America Movil’s broadband investment priorities across Latin America?

For America Movil, this transaction fits within a broader strategic posture of shoring up fixed broadband infrastructure across its Latin American footprint, where wireless remains the dominant revenue driver but fixed services are gaining increasing strategic importance. America Movil operates across more than 20 countries with over 300 million wireless subscribers, but its fixed broadband position has historically been weaker relative to its mobile dominance in key markets. Brazil, as the largest economy in Latin America, represents a critical battleground, and the Desktop acquisition reflects a willingness to deploy meaningful capital to close infrastructure gaps rather than rely solely on organic network investment.

America Movil reported strong fourth-quarter 2025 results, with revenue growth of 5.3% year over year excluding currency movements, and free cash flow increasing substantially to approximately MXN 58 billion for the full year. That financial position provides meaningful capacity to absorb a $753 million acquisition without material strain on the balance sheet. The company is also preparing for its Q1 2026 earnings on April 28, 2026, which will be the first quarterly report to include commentary on the Desktop deal’s strategic rationale from management.

How did Desktop stock price react to the Claro acquisition announcement and what does the OPA mean for shareholders?

Desktop’s shares delivered their strongest single-session move since the company’s 2021 listing, surging 23.26% to R$17.75 on the day following the announcement, after closing at R$14.40 the previous Friday. At the intraday peak, DESK3 rose approximately 25%. The reaction reflects a combination of deal certainty premium and relief among investors who had watched acquisition discussions surface and stall on multiple occasions over the preceding 18 months, including the earlier reported approach by Telefonica Brasil’s Vivo.

Despite the sharp move, DESK3 still traded at a meaningful discount to the R$20.82 OPA floor at close, reflecting the residual uncertainty around regulatory approvals and the timeline for the mandatory tender offer process. Shareholders who hold through the OPA should receive at minimum the R$20.82 transaction price, representing a premium of approximately 44.5% over the pre-announcement close. America Movil’s NYSE-listed ADR (AMX) was trading at approximately $25.39 as of March 25, 2026, up around 2.54% on the day, within a 52-week range of $13.10 to $26.16. The stock has recovered strongly from its 52-week low, though analysts at UBS raised their price target to $30 in late February, suggesting the market may not yet have fully priced in America Movil’s accelerating cash flow and ongoing portfolio strengthening.

What execution and integration risks does Claro face in absorbing Desktop’s fiber network and subscriber base?

The operational integration challenge is real and should not be underestimated. Desktop has built its subscriber base and network primarily in interior Sao Paulo cities, many of which have different competitive dynamics than the metropolitan areas where Claro’s infrastructure is most mature. Migrating over 1.2 million subscribers onto Claro’s systems, harmonising service offerings, and rationalising back-office functions across a geographically dispersed fiber network will take time and management bandwidth. There is also a customer retention risk during the transition period, as subscribers in smaller interior markets tend to be more sensitive to service disruption and may face competitive approaches from regional ISPs looking to capitalise on post-acquisition uncertainty.

The technology integration dimension adds another layer of complexity. Claro’s legacy HFC network infrastructure requires a different management and maintenance approach than Desktop’s pure-fiber platform. While the long-term direction of the combined entity is clearly toward fiber, the process of aligning network management systems, investment planning cycles, and field operations teams across two distinct infrastructure types is a multi-year programme. Claro will need to demonstrate disciplined capital allocation through the integration phase to justify the R$4 billion enterprise value and sustain the competitive momentum the transaction is intended to deliver.

Key takeaways: What the Claro and Desktop S.A. deal means for Brazil’s fiber broadband sector and investors

• Claro Telecom Participacoes S.A. is acquiring a 73.01% controlling stake in Desktop S.A. (B3: DESK3) for R$2.41 billion in equity value, at R$20.82 per share, within a R$4 billion enterprise value transaction backed by parent America Movil (NYSE: AMX).
• The deal is strategically driven by Claro’s need to close a significant fiber-only infrastructure gap: Claro holds only 6.6% fiber broadband market share nationally versus Vivo’s 15%, despite leading on total fixed broadband subscribers.
• Desktop’s 58,000-kilometer pure-fiber network across 200-plus cities in interior Sao Paulo gives Claro market leadership in those specific cities upon closing, a position that would have taken years and significant capital to build organically.
• Telefonica Brasil’s Vivo had earlier passed on acquiring Desktop over network overlap concerns, a decision that now cedes competitive ground in Sao Paulo interior markets to a strengthened Claro.
• H.I.G. Capital’s exit marks a strong private equity outcome, having grown Desktop from 150,000 to over 1.2 million subscribers through ten acquisitions and organic expansion, culminating in the first Brazilian ISP IPO in 2021.
• DESK3 shares surged 23.26% on announcement day, closing at R$17.75, with a 44.5% premium to pre-deal close embedded in the R$20.82 OPA floor price to be offered to remaining minority shareholders.
• Regulatory clearance from CADE and Anatel is required, followed by a mandatory OPA under CVM rules for the remaining 26.99% of shares, with Desktop likely to be fully delisted from the B3 post-transaction.
• The deal accelerates Brazil’s mid-tier ISP consolidation narrative, signalling that large integrated operators are moving up the acquisition curve from small regional players toward nationally significant fiber assets.
• America Movil (AMX) enters the transaction from a position of strengthened financials, having reported an 80% increase in free cash flow in 2025 and carrying analyst price targets as high as $30, with UBS upgrading the stock to Buy in late February 2026.
• Integration execution risk is real: harmonising Desktop’s pure-fiber platform with Claro’s hybrid HFC legacy network, retaining subscribers during the transition, and maintaining service quality across a geographically dispersed interior Sao Paulo footprint will be the key operational tests for Claro’s management over the next 18 to 24 months.
