Copa Holdings CPA is scheduled to report first-quarter 2021 earnings on May 5, after market close.The Zacks Consensus Estimate for first-quarter loss has narrowed to $2.21, from $2.31, 60 days ago. Let’s take a look at the factors that are expected to have influenced the company’s performance in the March quarter.Improvement in air-travel demand in Latin America is expected to reflect in Copa Holdings’ passenger revenues. The Zacks Consensus Estimate for first-quarter passenger revenues indicates a 23.6% rise from the fourth-quarter 2020’s reported number. However, since travel demand continues to lag the pre-pandemic levels, the consensus mark for passenger revenues shows a 68.2% decline from the first-quarter 2020’s reported figure.With this anticipated decline in passenger revenues, the company’s top line is likely to have been significantly affected when compared on a year-over-year basis. The company anticipates total revenues for the first quarter to be in the range of $170-$200 million. The Zacks Consensus Estimate for the same is pegged at $187.93 million, indicating a drop of 68.4% from the year-ago period’s reported number. However, the same suggests an 18.5% improvement from the fourth-quarter 2020 reported figure.In response to the tepid demand, the airline reduced its capacity significantly. The Zacks Consensus Estimate for capacity, measured in available seat miles/ASMs, hints at a 53.3% plunge from the year-ago quarter’s reported level. The company estimates its first-quarter 2021 capacity to be around 40% of the 2019 levels.Copa Holdings, S.A. Price and EPS Surprise Copa Holdings, S.A. price-eps-surprise | Copa Holdings, S.A.
