CMS ENERGY ANNOUNCES FIRST QUARTER EARNINGS OF $0.75 PER SHARE
AND REAFFIRMS ADJUSTED EARNINGS GUIDANCE OF
$1.74 TO $1.78 PER SHARE

JACKSON, Mich., April 24, 2014 — CMS Energy announced today reported net income of $204 million, or $0.75 per share, for the first quarter of 2014, compared to reported net income of $144 million, or $0.53 per share, for the same quarter of 2013.  Adjusted (non-Generally Accepted Accounting Principles) net income for the first quarter for both years was the same as reported amounts.

CMS Energy reaffirmed its guidance for 2014 adjusted earnings of $1.74 to $1.78 per share.  This is consistent with the company’s long-term plan of 5 percent to 7 percent annual earnings per share growth.

First quarter results reflect execution of its business plan and the effects of extreme cold weather which increased natural gas deliveries and electric sales, compared to more normal first quarter weather in 2013.  The company is reinvesting proceeds from higher cold weather sales into the business with a continued focus on the environment, safety, reliability, and customer service.

John Russell, CMS Energy’s president and chief executive officer, said that CMS Energy’s principal subsidiary, Consumers Energy’s substantial investments in its natural gas infrastructure improved the system performance.

“Despite near record cold and snow this winter, our gas customers received safe and reliable supply.  This performance underscores that our long-term strategy to expand and strengthen our gas distribution, transmission and storage system is paying off for our customers,” Russell said.

The first quarter was the coldest in Michigan in 50 years and Consumers Energy’s total gas deliveries were 23 percent above plan.  The company’s natural gas storage system helped protect customers from winter price spikes by providing steady supplies and predictable costs, Russell noted.  Consumers Energy has one of the largest gas storage systems in the country with the highest level of deliverability at 4 billion cubic feet per day.

“We’ve invested more than $355 million in recent years to expand and strengthen our natural gas system. The system was tested this winter and it delivered.”

Looking forward, Russell said another example of the company’s plan to invest in its gas system is the $120 million 24-mile Southwest Michigan pipeline project.  Scheduled for

fourth quarter operation, the project completes a 90-mile dual gas transmission pipeline corridor, which will increase value, reliability and safety for Consumers Energy’s 1.7 million natural gas customers.  The project is creating 175 jobs.

Economic indicators in Consumers Energy’s Michigan service territory continue to point to good recovery and job growth.  Several industries have announced expansion projects and electric sales to industrial customers are expected to grow by about 2 percent per year. Michigan has experienced six consecutive months of jobs growth and the state’s seasonally adjusted unemployment rate is now the lowest since the second quarter of 2008.

Consumers Energy is supporting the state’s economic recovery through its commitment to increase by $1 billion its purchase of Michigan-made goods and services over five years, from 2011-2016, as part of Pure Michigan Business Connect.  This is in addition to the more than $2 billion the company spends each year in Michigan.

Other quarterly highlights include the company’s announcement to purchase, with plans to close the transaction in late 2015, a 540 megawatt natural gas plant in its hometown of Jackson, Michigan to largely replace seven older coal plants, and a new program to purchase renewable energy from anaerobic digesters operated primarily by Michigan farmers.

CMS Energy (NYSE: CMS) is a Michigan-based company that has an electric and natural gas utility, Consumers Energy, as its primary business and also owns and operates independent power generation businesses.
