Integrys Energy Group, Inc. Reports Fourth Quarter 2013 Earnings

Introduces 2014 Guidance Range for Diluted Earnings Per Share - Adjusted of $3.50 to $3.75

Chicago – February 26, 2014 – Integrys Energy Group, Inc. (NYSE: TEG) recognized earnings on a Generally Accepted Accounting Principles (GAAP) basis and an adjusted basis as follows:

	Quarter Ended December 31		Year Ended  December 31
	2013	2012	2013	2012
GAAP earnings (millions)	$131.6	$68.0	$351.8	$281.4
GAAP diluted earnings per share	$1.63	$0.86	$4.39	$3.55
Adjusted earnings (millions) *	$79.5	$70.2	$282.9	$258.4
Diluted earnings per share – adjusted*	$0.99	$0.89	$3.53	$3.26

Adjusted earnings exclude the effects of certain items that are not comparable from one period to the next.

FOURTH QUARTER RESULTS

Earnings for the fourth quarter increased $63.6 million on a GAAP basis and $9.3 million on an adjusted basis from 2012 to 2013. The increase in adjusted earnings was driven by the utility segments.

Adjusted earnings at the natural gas utility segment increased $11.4 million quarter over quarter. One of the main drivers of the increase was a rate increase at The Peoples Gas Light and Coke Company that was effective in June 2013. This rate increase included recovery of increased natural gas distribution costs. The other main driver of the increase in adjusted earnings was an increase in sales volumes driven by the impact of weather. In 2012, weather was unusually warm in the natural gas utilities' service territories and the majority of the natural gas utilities did not have the benefit of weather-related decoupling accruals to offset the negative impact of weather. Financial incentives earned by Minnesota Energy

Resources for achieving certain conservation improvement program goals also contributed to the increase in adjusted earnings.

An increase in adjusted earnings at the electric utility segment also contributed to the consolidated increase. The main driver of the electric utility increase was a retail electric rate increase at Wisconsin Public Service Corporation effective January 1, 2013.

A decrease in adjusted earnings at Integrys Energy Services, Inc. partially offset the increases at the utility segments. The decrease at Integrys Energy Services was mainly due to increased operating costs driven by the expansion of the residential and small commercial customer business.

EARNINGS FORECAST

Integrys Energy Group’s guidance range for 2014 diluted earnings per share on a GAAP basis is $4.10 to $4.35. This guidance assumes the availability of generation units and normal weather conditions for the rest of the year. Integrys Energy Group is not estimating the impact of derivative and inventory fair value accounting activities for 2014. The company's guidance range for 2014 diluted earnings per share – adjusted is $3.50 to $3.75.

Diluted Earnings Per Share – Adjusted

and Weather Impacts

Diluted Earnings Per Share Information (Non-GAAP Information)

We prepare financial statements in accordance with accounting principles generally accepted in the United States (GAAP). In addition, we disclose and discuss diluted earnings per share (EPS) – adjusted and adjusted earnings (loss), which are non-GAAP measures. Management uses these measures in its internal performance reporting and for reports to the Board of Directors. We disclose these measures in our quarterly earnings releases, on investor conference calls, and during investor conferences and related events. Management believes that diluted EPS – adjusted and adjusted earnings (loss) are useful measures for providing investors with additional insight into our operating performance. These measures allow investors to better compare our financial results from period to period, as they eliminate the effects of certain items that are not comparable. This additional information is not meant to be considered in isolation or as a substitute for our results of operations prepared and presented in conformance with GAAP. Tax impacts are calculated using the applicable combined federal and state statutory rate modified for any attributable permanent tax effect and/or tax credit.
