Inclusion recognizes commitment to advancing women in the workplace

MADISON, Wis. – January 16, 2019 – Alliant Energy is one of 230 companies worldwide selected for the 2019 Bloomberg Gender-Equality Index (GEI), which distinguishes companies committed to transparency in gender reporting and advancing women’s equality. The GEI includes firms from 10 sectors headquartered across 36 countries.

“Alliant Energy places great value on diversity and is pleased to be included in the Bloomberg Gender-Equality Index,” said Alliant Energy Chairman and CEO Patricia Kampling. “We are only successful if we create a workplace where all people feel like they belong.”

Bloomberg’s standardized reporting framework offers public companies the opportunity to disclose
information on how they promote gender equality across four separate areas – company statistics,
policies, community engagement, and products and services. Reporting companies that score above a globally established threshold, based on the extent of disclosures and the achievement of best-in-class statistics and policies, are included in the GEI.

The Bloomberg gender reporting framework is voluntary and has no associated costs. The GEI is a
reference index. All public companies can submit data to Bloomberg. Those with a security listed on a U.S. exchange and a market capitalization of $1 billion or greater are eligible for index inclusion.
