This research aimed to examine the effect of a Promotion strategy on the brewery company's performance. To achieve the study's objective, the researcher applied descriptive and explanatory research designs using a mixed-methods approach. For the research, both first-hand and second-hand sources of information were gathered. This research involved 310 employees of Ethiopia's brewery companies who completed questionnaires to obtain data. The study used simple random sampling. Using SPSS version 21.00, descriptive statistical methods, such as mean and standard deviation, and inferential statistical techniques, such as correlation and multiple regression analysis, were used to analyze the questionnaire data. According to the findings of this research, promotion strategy has a statistically significant and strong positive relationship with organizational performance. Moreover, the Promotion mix strategy and company performance have a strong positive and statistically significant association (r =.78.8, P < 0.01), and the promotion strategy explains 62 per cent of the variances in organizational performance substantially. The marketing department should develop a clear message and identify its target customers. The messaging should be updated regularly, and free items should be offered on weekends. The Promotion's goal should also serve as a reminder. The companies should use sales promotion, public relations, and direct marketing. Finally, promotional strategies should be connected to product planning, pricing, and distribution. This is because the uniqueness and price competitiveness of the product might impact Promotion. As a result, Promotion must be consistent with the other components of the marketing mix.
