| Abstract | ||
| Forecasting using time series analysis is an important process in both academic and commercial fields, which can be applied to solve many problems of real predictions through data analysis. Time series in studying and analyzing the annual data of a group of telecommunications companies (Asia Cell, Zain, Jordan Telecom) due to the high accuracy and flexibility of this model in financial analysis, and standing on the results through the use of time series, as the research dealt with a sample of (3) companies during a time series extending from (2012-2021), The variables were also measured quantitatively and statistically analyzed, as well as the sub-hypotheses were tested using the T-test. The research concluded that it is possible to predict future revenues and the expenditure ratio for the period (2022-2024) through actual analysis, as these values showed consistency with their counterparts in the original time series.
