Industrial companies often complement organic growth opportunities with value creating M&A. The rationale for acquisitions may include scale, new technologies, and attractive assets in a multi-industry portfolio of businesses.

The top industrial companies have demonstrated discipline by returning cash to shareholders after exhausting organic and inorganic investment opportunities. For example, Atlas Copco has paid $9 billion in regular dividends over the past 10 years, and on three occasions has paid special dividends worth a cumulative $3.3 billion.

Strategic use of financial leverage

Long lived assets and strong competitive advantages allows for the comfortable use of modest leverage to boost returns. Re-leveraging with debt to maintain a constant capital structure is often used to enhance cash flows and returns to equity holders. The strength of business models and competitive advantages can also provide firepower to flex debt levels higher to seek to capitalize on inorganic opportunities. For example, DSV has used leverage to make highly accretive acquisitions the past several years.
