Three key important performance measures of the Wireless Telecommunication industry are ARPU, Subscriber growth and Churn rate as they will provide insights into the firm's operational performance and future development prospects in a highly saturated market in the US. ARPU (average revenue per unit) ARPU shows the firm's capability in resource utilization by maximizing profits and minimizing costs, especially in a highly saturated and intensely competitive like Wireless Telecommunications market in the US where the profits have been plateaued (Investopedia, 2022; Simply Wall St, 2023). Higher ARPU are synonymous with having favored and competent performances (Acro Media, 2022). Hence, by examining firms ARPU, we will be able to arrive at conclusions on more effective strategies in the US highly competitive Wireless Telecommunications market. Subscriber growth Future growth of Wireless Telecommunications firms depends on its customer base (Investopedia, 2022). By examining Subscriber growth, we can observe whether the firm’s offerings are meeting customer demands (Matther, Orf, 2022). We believe that subscriber growth would act as an effective tool to envisage the firm’s possibilities in a highly mature and customer-centric market like the US Wireless Telecommunications market (DANO, 2022). Churn rate The churn rate is a metric that measures the number of subscribers that cancel their subscriptions (Investopedia, 2022). A low churn rate is ideal. Companies with high subscriber growth rate may even have relatively high churn rate, therefore it is important to take churn rate into account as it defines and limits the largest size the firm can achieve (Payal, 2021). Companies ranking: We decided to rank the five firms in each of the chosen performance metrics then finalize the ranking by considering its Average score. As for ARPU and Subscriber growth, the higher the figures are, the higher the ranking, whereas for the churn rate, the lower it is, the higher the ranking. The final rankings of the five firms are derived according to the average score, the lower the average, the higher ranking.
