The chief executive officer of Charlotte-based EnPro Industries Inc. saw an 18 percent decrease in compensation in 2018, according to a form filed with the Securities and Exchange Commission Wednesday.

Stephen E. Macadam, CEO and president of the company, received about $4.6 million in total compensation in 2018, down from the $5.6 million he made in 2017.

Macadam’s base salary remained nearly unchanged, but he earned over $950,000 less in his non-equity incentive plan compensation.

This compensation category increased to over $2.6 million for the CEO in 2017 from about $721,000 in 2016, but fell from 2017 to 2018.

Macadam will be retiring from the company on July 29 and will be succeeded by current COO Marvin Riley.

The current CEO will serve as vice chairman to help with the transition of the company’s leadership until the end of February 2020, following which he will resign from the board as well.

EnPro is an international manufacturer, specializing in high-performance products.

The company’s stock is trading at $66.96 Wednesday afternoon, down 32 cents from the closing price of $67.28 Tuesday.
