Abstract

Indonesia's telecommunications industry faces complex dynamics due to digital transformation and strategic mergers among operators. This research aims to analyze historical revenue patterns of PT Indosat Ooredoo Hutchison Tbk for the 2020-2024 period and project 2025 revenue using the least square method. Secondary data was obtained from official company financial reports verified through multiple sources. Least square analysis was applied with 2022 established as the base year to facilitate mathematical calculations. Research findings reveal consistent revenue growth trends from IDR 27.93 trillion (2020) to IDR 55.89 trillion (2024), with a significant 49% surge in 2022 post-merger. The obtained regression equation is Y = 42,636,389 + 7,576,289X, yielding a 2025 revenue projection of IDR 65.37 trillion, representing 17% growth compared to the previous year. These findings indicate successful merger synergies in creating sustainable growth momentum. Strategic implications demonstrate the necessity for optimizing digital infrastructure investments, expanding market segmentation, and enhancing operational efficiency to achieve projection targets. This research provides practical contributions for corporate strategic decision-making and proves the effectiveness of quantitative methods in telecommunications industry financial planning
