Millicom International Cellular S.A. reported strong top-line expansion for the six months ended June 30, 2026. Revenue reached $4,164 million, up 52.3% year-on-year, with service revenue of $3,900 million, driven by consolidation of Coltel in Colombia, the 2025 acquisitions in Ecuador and Uruguay, and currency appreciation. Adjusted EBITDA rose to $1,866 million (up 46.8%), and operating profit was $877 million. Net cash from operating activities increased to $1,301 million, while equity free cash flow excluding divestitures grew to $552 million.
Despite this, net profit attributable to owners declined to $218 million (EPS $1.30) from $869 million, reflecting the absence of last year’s $604 million Lati gain, higher depreciation and amortization, increased net financial expenses of $516 million, and a $32 million goodwill impairment in Costa Rica. Total assets rose to $20,679 million, with net debt of $8,075 million and leverage at 2.73x. Based on the stronger cash generation, Millicom raised its 2026 equity free cash flow guidance to around $1.1 billion and lowered its year-end leverage target to below 2.5x. Shareholders approved a $3.00-per-share dividend, and the board later authorized an additional interim dividend of $1.50 per share for early 2027. Management also notes employment-related proceedings in Guatemala and a new, more volatile FX regime in Bolivia as key uncertainties, while the independent auditor’s review concluded the interim financial statements comply with IAS 34.
MILLICOM INTERNATIONAL CELLULAR SA director Blanca Trevino de Vega reported a small equity grant and related tax withholding in common shares. She received 1,420 common shares as a grant or award at a stated price of $0.00 per share, increasing her direct holdings to 14,447 shares.
On the same date, 284 common shares were withheld by the issuer solely to satisfy tax obligations incurred upon the transfer, with a reference price of $73.92 per share used for valuation. This withholding was not an open‑market sale and represents a routine, non‑market adjustment tied to the equity award.
MILLICOM INTERNATIONAL CELLULAR SA director Justine Dimovic had 1,420 common shares granted as equity compensation and 284 shares withheld for taxes. The 284-share entry is coded as a sale but the issuer explains it only withheld shares to satisfy tax obligations on the transfer, using a reference price of $73.92 per share. After these transactions, Dimovic directly holds 8,562 common shares.
Millicom International Cellular SA director Bruce Churchill reported equity compensation activity involving the company’s common shares. On 20 May 2026, he received a grant of 1,420 common shares, recorded at no cash price. In connection with this award, the issuer withheld 284 common shares to satisfy tax obligations incurred upon transfer, based on a reference value of $73.92 per share. After these transactions, Churchill directly holds 26,729 common shares of Millicom.
MILLICOM INTERNATIONAL CELLULAR SA director Maria Teresa Arnal reported a compensation-related share grant combined with tax withholding. She received 1,420 Common Shares as a grant or award, while 284 Common Shares were withheld by the issuer solely to cover tax obligations on the transfer.
Following these transactions, she directly holds 14,163 Common Shares. Because the 284-share disposition was tax withholding rather than an open-market sale, the activity mainly reflects routine equity compensation rather than a discretionary trade in the company’s stock.
