M&A Commentary and Trend Analysis Today's Tech/Comm M&A drivers are different than those at the height of the IT spending boom and the stock market bubble. In the current period of low earnings and restrictive capital markets, companies are inclined to improve profit margins and capital efficiency. We believe these conditions form the principal drivers of Tech/Comm M&A today: 1) back to core competencies, 2) consolidation, and 3) bargain hunting.
