The impact of enterprise application integration on stock prices

Enterprise application integration (EAI) technologies are critical to functionally integrate diverse corporate computer systems, and as such may be expected to have a positive effect on business value. The purpose of this paper is to examine the market reaction to announcements of EAI investments as a surrogate for investor perceived business value of such technology.

An event study approach is used with 81 announcements of EAI investments between 1998 and 2005, taken from Lexis‐Nexis database.

The results suggest that investors do not always receive EAI investments positively, especially if the announcements are from financially distressed companies and if market conditions are unfavorable.

Limitations include the possibility of confounding events, possible bias in the identified announcements, and our focus on EAI technology only. Future research may try to better account for confounding events, identify a more comprehensive list of relevant announcements, and also look at other technologies.

Managers should not view EAI technology as a panacea for organizational problems. Financial markets mostly respond negatively to EAI announcements when the announcing company is perceived as an investment risk or the announcement is released during bear market conditions.

This study expands the existing body of knowledge on IT contribution to market value. The focus on EAI technology allows for better comparison of results and testing of hypotheses. Also new is the finding that perceived company risk as well as market conditions play an important role in the reaction to IT investment announcements.
