Brand image strategy affects brand equity after M&A

Abstract
Purpose: The purpose of this study is to examine the relationship between the variance of two brand images and dimensions of brand equity after M&A, especially when the acquirer‐dominant is affiliated to a weak brand image and the acquired one has a stronger brand image.Design/methodology/approach: In total, 409 responses were collected through random sampling from an internet survey platform in Taiwan (weak image differences were gathered from 209 respondents and strong image differences were gathered from 200 respondents).Findings: This study uses an experimental design to discuss how the variance of two brand images (this study uses two kinds of M&A: a company with an inferior brand image acquires one with a superior or average brand image) affects the acquirer's brand equity (perceived quality, brand association, and brand loyalty). This study also examines how brand equity of an acquired brand changes after M&A. Results from the MANOVA and paired‐sample t‐test methods show that the greater the perceived differences between acquirers and acquired brands, the more the brand equity of the acquirer will increase. In addition, all the dimensions of brand equity for the brand with a superior image decrease significantly.Originality/value: Few studies have evaluated the brand image effect of an M&A from a marketing perspective. The contribution is to help managers understand whether the acquirer should preserve the obtained brand and focus on increasing brand equity of the acquired brand to avoid the loss of customer loyalty.
