NGP ETP invests in companies that provide technology-related products and services across the energy spectrum. Our objective is to partner with dynamic management teams to enhance the growth of businesses and create value. Leveraging our extensive industry and transaction experience, we actively participate in developing robust working relationships with our portfolio companies without micromanaging.
We look for companies with strong and experienced management teams that have developed compelling business plans and identified sizeable market opportunities. Our focus is on businesses with commercial products or services that have existing revenue and a significant competitive advantage. We also provide capital to businesses to facilitate acquisitions or consolidation strategies. Our typical equity investment ranges between $5 million and $20 million per company, although we have led investment rounds of up to $100 million. NGP ETP's investments can take the form of either growth or buyout capital. Our growth capital investments typically represent a minority, non-control position, with proceeds used to fund a company's strategic plan. Our buyout capital investments typically represent a majority control position through the acquisition of equity from existing shareholders and can be accompanied by the use of leverage for EBITDA positive businesses.
Our preference is to lead transactions and invest in North American companies, although we take an opportunistic view on our sector and are always open to hearing from high-quality management teams that believe our firm can add unique value to their story.
