Abstract: In this paper, we investigate whether a firm can enhance the effect of its R&D spending on its current market value and future profitability through technology-oriented M&As. On the basis of an analysis of 1,879 M&As, we find that when a technology firm acquires another technology firm, the magnitude of the stock price response to the R&D spending of an acquirer increases by 107% in the year of the M&A. In contrast, we find no such increase in the stock price response to the R&D spending of a non-technology acquirer. We also find that technology acquirers are more successful in converting their R&D spending into positive future profitability than non-technology acquirers. Our results are robust for different alternative specifications of our model and when various firm differences are controlled for.
