Millicom International Cellular (TIGO) is trading higher as the market focuses on its upcoming dividend catalyst. Corporate filings and dividend trackers show an April 8, 2026 ex-dividend date, with an April 15, 2026 payment date for a $1.25-per-share installment tied to Millicom’s previously announced special interim dividend plan.

When a stock approaches its ex-dividend date, incremental demand can appear from dividend-focused investors and short-term traders seeking to capture the payment. That dynamic can support shares into the ex-date, though the stock price often adjusts downward by roughly the dividend amount on or shortly after the ex-dividend date, all else equal.

Separately, a recent amended Schedule 13D/A disclosed that Atlas Investissement increased the maximum amount available under secured equity financing by about $190 million, a structure that can be used to support additional share purchases over time. The disclosure has been circulating as a supportive technical backdrop alongside the dividend setup. (stocktitan.net)

Key near-term dates are April 8, 2026 (ex-dividend) and April 15, 2026 (payment). Traders will also watch for follow-through volume after the ex-date and any additional large-holder filings that could confirm continued demand. (cdn.financialreports.eu)
