Millicom's Q2 Script: Pretend Last Quarter's Forty Percent Miss Was a Typo
Millicom International Cellular S.A. (TIGO) reports second-quarter 2026 earnings tomorrow, August 6, before market open, with analysts expecting $0.54 per share. The Latin American telecom operator faces a critical test after delivering wildly inconsistent results over the past year, swinging from a 43% beat to a 38% miss. With the stock trading near its highs and analyst sentiment deteriorating, investors will scrutinize whether management can sustain the momentum from its Colombian acquisition integration while maintaining profitability.
Part 1: Earnings Preview
Millicom International Cellular S.A. operates mobile and fixed-line telecommunications networks across Latin America, serving markets in Central America and South America with mobile, cable, and digital services. The company has been integrating a major Colombian acquisition while navigating competitive pressures and currency headwinds in its core markets.
TIGO reports second-quarter 2026 results tomorrow, August 6, before market open. Analysts expect earnings of $0.54 per share on revenue of approximately $2.12 billion. The company most recently reported first-quarter earnings of $0.97 per share, which beat estimates by 9% but represented a significant deceleration from the prior quarter's blowout performance.
Compared to the same quarter last year when TIGO earned $0.51 per share, the consensus implies modest 6% year-over-year growth. However, this muted outlook masks significant underlying volatility in the business.
Three key themes define this earnings story:
Colombian Integration Execution: Following its transformative acquisition in Colombia, investors are watching whether Millicom can maintain the operational leverage CEO Ramos emphasized last quarter. The company achieved record Q1 equity free cash flow of $225 million while posting 35.5% adjusted EBITDA growth, but integration costs pressured margins. The critical question is whether management can sustain these cash generation levels while completing the integration.
Revenue Growth Sustainability: Organic service revenue grew 4.9% in Q1, but the company faces a challenging comparison as it laps the Colombian acquisition anniversary. With analysts projecting 55% year-over-year revenue growth for Q2, the market is pricing in continued strong top-line momentum. Any deceleration could trigger concerns about competitive dynamics in key markets.
Profitability Trajectory: The consensus estimate of $0.54 represents a sharp decline from Q1's $0.97, raising questions about seasonal patterns and margin pressure. Management's ability to balance growth investments with profitability will be crucial, especially given the wide analyst estimate range from $0.37 to $0.70.
Analyst commentary ahead of the release reflects cautious optimism tempered by execution concerns. While the company's guidance for Q2 EPS of $0.70 and Q3 of $0.85 signals management confidence, the recent deterioration in analyst sentiment—with one analyst downgrading to Strong Sell in the past month—suggests growing skepticism about the sustainability of recent outperformance.
Part 2: Historical Earnings Performance
Millicom's earnings track record over the past four quarters reveals extreme volatility that should give investors pause. The company has alternated between significant beats and misses, with no consistent pattern of execution.
In Q2 2025, TIGO missed estimates by 6%, delivering $0.51 versus the expected $0.54. The following quarter brought a dramatic 38% miss, with actual earnings of $0.34 falling far short of the $0.55 consensus. Q4 2025 marked a sharp reversal with a massive 43% beat—$1.50 versus $1.05 expected—only to be followed by a more modest 9% beat in Q1 2026 at $0.97 against $0.89 estimates.
This erratic pattern suggests either significant challenges in forecasting the business or genuine operational volatility stemming from the Colombian acquisition integration, currency fluctuations, and competitive pressures across Latin American markets. The wide swings make it particularly difficult to handicap tomorrow's results with confidence, as the company has demonstrated it can both dramatically exceed and badly miss expectations within the span of consecutive quarters.
| Quarter | EPS Estimate | EPS Actual | Surprise % | Beat/Miss |
|---|---|---|---|---|
| Jun 2025 | $0.54 | $0.51 | -5.56% | Miss |
| Sep 2025 | $0.55 | $0.34 | -38.18% | Miss |
| Dec 2025 | $1.05 | $1.50 | +42.86% | Beat |
| Mar 2026 | $0.89 | $0.97 | +8.99% | Beat |

Part 2.1: Price Behavior Around Earnings
TIGO reports before market open, meaning Day 0 captures the first full trading session reaction while Day +1 reflects follow-through momentum.
| Earnings Date | Day 0 Move | Day 0 Range | Day +1 Move | Day +1 Range |
|---|---|---|---|---|
| 2026-05-12 | +$1.63 (+2.08%) | $11.72 (14.93%) | +$1.85 (+2.31%) | $3.08 (3.84%) |
| 2026-02-26 | +$3.98 (+5.97%) | $4.78 (7.16%) | +$2.21 (+3.13%) | $3.99 (5.65%) |
| 2025-11-06 | +$1.73 (+3.76%) | $2.84 (6.17%) | -$0.28 (-0.59%) | $1.16 (2.43%) |
| 2025-08-07 | +$3.03 (+7.59%) | $4.29 (10.73%) | -$0.92 (-2.14%) | $0.94 (2.18%) |
| 2025-05-08 | +$0.24 (+0.71%) | $4.08 (12.01%) | +$0.59 (+1.72%) | $1.48 (4.32%) |
| 2025-02-27 | -$0.71 (-2.55%) | $1.87 (6.71%) | -$0.87 (-3.20%) | $0.63 (2.32%) |
| 2024-11-07 | -$0.46 (-1.71%) | $0.70 (2.59%) | +$0.73 (+2.76%) | $0.66 (2.50%) |
| 2024-08-02 | +$1.32 (+5.36%) | $0.39 (1.58%) | -$0.67 (-2.58%) | $0.40 (1.54%) |
| Avg Abs Move | 3.71% | 7.74% | 2.30% | 3.10% |
Historical price behavior around earnings shows TIGO typically delivers significant volatility, with an average absolute Day 0 move of 3.71% and an average intraday range of 7.74% on earnings day. The Day +1 follow-through averages 2.30% with a 3.10% range.
The most recent earnings on May 12, 2026, produced a relatively muted reaction with a 2.08% Day 0 gain despite the earnings beat, followed by 2.31% Day +1 appreciation. However, earlier reports triggered much larger swings—the August 2025 report saw a 7.59% Day 0 surge, while February 2026 delivered a 5.97% pop. The pattern suggests TIGO can move sharply in either direction depending on the magnitude of the surprise and forward guidance, with initial reactions sometimes extending into the following session.
Part 2.2: Options Market Expected Move
| Metric | Value |
|---|---|
| Expiration Date | 08/21/26 (DTE 16) |
| Expected Move | $10.12 (11.02%) |
| Expected Range | $81.68 to $101.91 |
| Implied Volatility | 73.19% |
The options market is pricing an 11.02% expected move for the August 21 expiration, significantly higher than the 3.71% average historical Day 0 move. This elevated implied volatility suggests options traders are anticipating a larger-than-typical reaction to tomorrow's results, possibly reflecting uncertainty around the Colombian integration progress and the wide range of analyst estimates.
Part 3: What Analysts Are Saying
Analyst sentiment on TIGO has deteriorated recently, with the consensus rating standing at 3.00 (Hold) compared to 3.29 a month ago. The current breakdown shows 2 Strong Buy ratings, 3 Hold ratings, and 2 Strong Sell ratings among 7 analysts covering the stock—notably, one analyst downgraded to Strong Sell in the past month.
The average price target of $86.90 implies approximately 5% downside from the current price of $91.79, a bearish signal heading into earnings. However, the wide target range from a low of $52.40 to a high of $100.00 reflects significant disagreement among analysts about the company's valuation and prospects.
The shift in sentiment appears driven by concerns about the sustainability of recent outperformance and questions about whether the Colombian acquisition can deliver the promised synergies without continued margin pressure. The fact that the mean target sits below the current stock price suggests the analyst community believes much of the positive integration story is already priced in, leaving limited upside unless management delivers a significant positive surprise tomorrow.
Part 4: Technical Picture
The Barchart Technical Opinion rates TIGO as an 80% Buy signal, down from 88% last week and 100% a month ago, indicating weakening momentum as the stock approaches earnings.
Timeframe Analysis:
- Short-term (50% Buy): Moderate buy signal suggests near-term momentum has cooled considerably from recent highs
- Medium-term (100% Buy): Strong buy signal indicates the intermediate trend remains firmly positive despite recent softness
- Long-term (100% Buy): Strong buy signal reflects solid uptrend over the extended timeframe, supported by the stock's position well above longer-term moving averages
Trend Characteristics: The combination of Strong strength with Weakest direction suggests TIGO remains in a technically sound uptrend but is experiencing its most significant loss of momentum in recent months, creating a more uncertain setup heading into the earnings catalyst.
The stock trades at $91.79, below its 5-day ($93.92), 10-day ($94.56), and 20-day ($95.67) moving averages, indicating recent weakness. However, TIGO remains above its 50-day ($91.30), 100-day ($85.63), and 200-day ($71.27) moving averages, confirming the longer-term uptrend remains intact.
| Period | Value | Period | Value |
|---|---|---|---|
| 5-Day MA | $93.92 | 50-Day MA | $91.30 |
| 10-Day MA | $94.56 | 100-Day MA | $85.63 |
| 20-Day MA | $95.67 | 200-Day MA | $71.27 |
The technical picture presents a mixed setup for earnings. While the stock maintains a solid position above all major long-term moving averages—trading 29% above its 200-day—the recent pullback below short-term averages and deteriorating momentum indicators suggest some profit-taking ahead of the report. The 50-day moving average at $91.30 now serves as immediate support, with the stock trading just 0.5% above that level. Given the options market's expectation of an 11% move and the stock's recent loss of momentum, the technical setup appears cautiously positioned rather than supportive, with traders seemingly reducing exposure ahead of what could be a volatile reaction to results.
