A DECADE OF DIVERGENCE: FINANCIAL RATIO ANALYSIS AND TWO-WAY ANOVA EVIDENCE FROM INDIAN TELECOMMUNICATIONS COMPANIES (FY 2013–14 TO FY 2022–23)

Abstract

This paper presents a comprehensive longitudinal and comparative financial performance analysis of four major Indian telecommunications operators — Bharti Airtel Limited, Tata Teleservices, Mahanagar Telephone Nigam Limited (MTNL), and Reliance Jio Infocomm — over the ten-year period from FY 2013–14 to FY 2022–23. Eighteen financial ratios spanning four analytical categories — profitability, capital structure, working capital management, and asset activity — are computed from audited annual reports and subjected to Two-Way Analysis of Variance (ANOVA) to determine whether observed inter-company and inter-year differences are statistically significant. The ANOVA results demonstrate that the Company effect is statistically significant in 17 of 18 ratios (at p < 0.05), while the Year effect is significant in only 1 of 18 ratios, indicating that firm-specific structural attributes — legacy cost structures, capital structure decisions, spectrum portfolios, and workforce models — are the dominant determinants of financial performance variation in the sector, rather than macroeconomic or regulatory cycles. Reliance Jio emerges as the clear financial performance leader by FY 2022–23, with a Gross Profit Ratio of 39.50%, ROCE of 20.18%, EBITDA margin of 59.8%, and an Interest Coverage Ratio of 4.46 — the only operator satisfying the benchmark ICR threshold of 2.0. Bharti Airtel demonstrates a robust recovery from AGR-induced distress, while MTNL exhibits unidirectional financial deterioration across all metrics throughout the study period. The paper concludes with theoretical implications grounded in the DuPont Decomposition Framework, Agency Theory, and the Resource-Based View of the firm.
