TIGO files a notice to sell 11,500 common shares related to restricted stock vesting under a registered plan, with an apparent filing date of 02/27/2026.
The entry lists two vesting events of 7,267 shares (01/01/2026) and 4,233 shares (01/01/2025). The excerpt also shows a sale of 1,860 common shares on 12/29/2025 for $102,281.40.
Millicom International Cellular S.A. reports a very strong Q4 and full-year 2025, highlighted by record profitability and cash generation. Full-year revenue was $5.8 billion, essentially flat year-on-year, but operating profit rose to $1.6 billion and net profit attributable to owners surged to $1.3 billion, mainly helped by a $741 million gain on the $975 million Lati tower portfolio sale.
Service revenue grew organically 2.8% in 2025 and 5.2% in Q4, while Adjusted EBITDA increased 11.4% to $2.75 billion, lifting operating cash flow to $2.03 billion and equity free cash flow to $916 million. The balance sheet expanded as total assets reached $17.3 billion and debt and financing rose to $6.9 billion, though management states leverage remained below 2.5x.
Millicom also executed several strategic moves, including acquisitions in Uruguay and Ecuador, and later agreed to acquire remaining shares in Tigo Colombia and Telefónica’s controlling stake in Coltel, plus a joint deal for Telefónica’s Chile operations. The company adopted amended IAS 21, recording a $188 million negative equity adjustment, and entered 2026 targeting at least $900 million of equity free cash flow and year-end leverage around 2.5x.
Atlas Investissement SAS and related parties report beneficial ownership of 70,470,018 common shares, or 42.2%, of Millicom International Cellular S.A. This percentage is based on 167,092,668 shares outstanding as of October 31, 2025. The amendment also discloses a Call Option Agreement among NJJ Cactus SAS, Millicom Spain, S.L. and Celtel Chile, S.L. tied to the acquisition of Telefonica Moviles Chile S.A. Millicom Spain receives a call option exercisable during two 30-day periods after the fifth and sixth anniversaries of the Target’s purchase, with the price payable in cash and newly issued Millicom shares determined by a volume-weighted average price.
Millicom International Cellular S.A. is acquiring Telefonica’s Chilean business through a jointly controlled vehicle owned 51% by NJJ and 49% by Millicom. Telefonica will receive an initial closing payment of $50 million, plus potential earn-out payments of up to $150 million tied to structural value creation and paid from the acquired company’s cash flows.
The acquired business’s debt and transaction obligations are explicitly non-recourse to Millicom, and the business will not be consolidated in Millicom’s financial statements during joint ownership. At closing, Telefonica must contribute CLP 79 billion (about $92 million) to support payments and balance sheet stability.
Millicom will operate the Chilean business from day one and apply its regional playbook, while preserving its balance sheet through this partnership structure. Millicom holds call options in years five and six post-closing to acquire NJJ’s stake at a 10% discount to Millicom trading multiples, with a mirror option for NJJ if Millicom does not exercise, reinforcing long-term strategic positioning in Chile and South America.

The filing discloses new secured equity financing arrangements. On November 12, 2025, Atlas entered into four master agreements for prepaid forwards and equity swaps with major banks, together constituting an approximately USD 800 million transaction secured by pledges over Atlas’s TIGO shares and including margin call mechanisms. The stated purpose is to refinance the Senior Facilities Agreement and pay related costs; any excess cash may be used for working capital. The disclosure notes these transactions do not require the purchase of any Common Shares by Atlas or the counterparties.
Millicom (TIGO) announced a final resolution of a DOJ investigation involving historical improper payments by its Guatemalan subsidiary, Comunicaciones Celulares S.A. (Comcel), from a period when Millicom lacked operational control. The matter is being resolved through a deferred prosecution agreement that will remain in place for two years and does not require a corporate monitor.
Financial terms include a $60 million fine and forfeiture of $58.2 million in approximate benefits. The fine reflects a 50 percent discount off the bottom end of the U.S. Sentencing Guidelines range, which the company attributes to its 2015 voluntary self-disclosure, extensive cooperation, and remediation. Millicom will report to DOJ on its compliance program during the term of the DPA. The company emphasized that it strengthened compliance after gaining full ownership of Comcel in 2021 and has since exited personnel involved in misconduct.

Millicom (Tigo) completed its USD 380 million acquisition of Telefónica’s telecommunications operations in Ecuador, advancing its South America strategy. The deal adds a new, dollarized market with stable fundamentals and strong demand for digital services.
