Founded in 1958 as the Society of Independent Gasoline Marketers of America (SIGMA), SIGMA has become a fixture in the motor fuel marketing industry. After more than fifty years of leadership, SIGMA is the national trade association representing the most successful, progressive, and innovative fuel marketers and chain retailers in the United States and Canada. From the outset, the association has served to further the interests of both the branded and unbranded segment of the industry while providing information and services to members.
SIGMA’s approximately 260 corporate members command nearly 50 percent of the petroleum retail market, selling approximately 80 billion gallons of motor fuel each year. These member companies operate throughout the United States and Canada.
SIGMA’s benefits to member companies include government relations representation before Congress and the Administration, a wide variety of publications and timely mailings, as well as legal advice. The association holds meetings throughout the year to allow marketers and fuel suppliers to meet one-on-one and to give members a chance to participate in informative educational sessions. Leadership of the organization is provided by volunteers from SIGMA’s member companies, giving the association the advantage of advice from some of the most well-respected entrepreneurs in the nation.
SIGMA’s policies and operating procedures are determined by its members through the Board of Directors and volunteer committees.
Regular membership in SIGMA is available to companies involved in motor fuel retailing or wholesaling that are not owned by a refiner. Associate membership is open to other companies directly related to the manufacture or sale of motor fuels. In addition, Associate membership is available to companies that offer financial services, fuel transport services, and fleet card services.
SIGMA member companies have long been recognized, both within and outside the industry, as the most aggressive, innovative, and price competitive segment of petroleum marketers.
