The importance of making the right strategic decisions about business development has now become universal for both Russian and foreign companies. At the same time, the level of uncertainty is growing in relation to the factors that determine the parameters of the directions of development. In such a situation, the role of models, with the help of which it is possible to justify the choice of strategies, seriously increases. This article presents the author's typology of strategies as a basis for building such models at the next stages of the study. The empirical research base includes data on 2904 mergers and acquisitions in the electricity industry from 1999 to 2019. The author's method of typologizing integration and diversification strategies based on an analysis of the industry affiliation of companies using the NAICS 2017 index is proposed. The practical significance of the study lies in the possibility of using the type of strategy as a factor influencing the choice of corporate strategies by predicting the parameters of mergers and acquisitions.
