FORT COLLINS, Colo., Sept. 16, 2015—Advanced Energy Industries, Inc. (Nasdaq:AEIS) today announced a formalized capital deployment strategy. Over the past several quarters, Advanced Energy has embarked on a strategic transformation to build a strong model around its core precision power business. An integral part of this model is the company's strong cash generating capabilities and current balance sheet. In keeping with the company's overall objectives, the capital deployment strategy is centered on increasing shareholder value by investing in long-term growth opportunities and making distributions to shareholders.

Advanced Energy's capital deployment strategy encompasses the following:

1. organic investments to grow its market leadership in semiconductor applications, expand into industrial markets and increase its geographic presence;
    
2. acquisitions to increase the company's total addressable market with a particular focus on industrial products and applications;
    
3. share repurchases to meaningfully reduce share count over time; and
    
4. a more flexible capital structure that may include debt instruments to fund key investments.

Overall, the company aspires to deploy approximately 70% of its future free cash flow to organic investments and acquisitions and 30% to share repurchases.

"Today's announcement is a key component in our broader strategy to effectively deploy our cash," said Yuval Wasserman, President and CEO of Advanced Energy. "Our differentiated business model continues to drive significant profitability and cash flow generation, allowing us the flexibility to pursue organic and inorganic initiatives to grow and diversify revenue, add to earnings per share growth and enhance capital returns. This program reaffirms our confidence in the long-term opportunity for AE and our ability to provide the best return to our shareholders."

The company also announced today that its Board of Directors has authorized it to repurchase up to $150 million of its common stock over the next 30 months. Purchases under the program may be made from time-to-time in the public or private markets, through block trades, Rule 10b5-1 trading plans or other available means and may include the use of derivative contracts and structured and accelerated share repurchase agreements. There is no minimum number of shares to be repurchased under the program, and it may be suspended or discontinued at any time. As of June 30, 2015, the company had approximately $183 million in cash and marketable securities and approximately 41 million common shares outstanding.
