Integrys Energy Group, Inc.
Termination of Stock Investment Plan
Q&A

Q1: When the merger closes, what will happen to the shares that I hold in the Stock Investment Plan and/or dividend reinvestment plan/DRIP/DRP?

A: Under the terms of the merger agreement with Wisconsin Energy, the Stock Investment Plan (Plan) will be terminated effective June 10, 2015, prior to the merger effective date.  Once the Plan is terminated, no further purchase right under the Stock Investment Plan will be granted to Plan participants.  The employee payroll deduction for share purchases will be stopped prior to the merger effective date.

We will deliver to you book-entry (direct registration) shares for any whole shares credited to your account under the Plan.  We will make a cash payment for any fractional shares credited to your account under the Plan.  The Plan administrator, American Stock Transfer, will roll-up all of the fractional shares for all Plan participants and sell the accumulated full shares in the open market.  The sale price obtained in the open market is used to determine your cash payment in lieu of fractional shares.

Q2: Why is the Stock Investment Plan being terminated?
A: Under the terms of the merger agreement with Wisconsin Energy, the company is required to terminate the Stock Investment Plan prior to the close of the merger.  In order to meet this requirement and to provide Plan participants with timely notice, the Plan is being terminated effective June 10, 2015.

Q3: As an employee of the company, I am able to purchase company stock without a commission through the Stock Investment Plan.  This is a benefit of being an employee of the company.  If you agreed not to change employee benefits for one year; how is it possible that you are discontinuing payroll deduction for the purposes of purchasing shares without a commission?

A: The Stock Investment Plan is not considered to be an employee benefit plan.  See the Benefits page of PowerNet for more information on our employee benefit plans.  We are required to terminate the Stock Investment Plan under the terms of the merger agreement with Wisconsin Energy.  In addition, please see Q&A 4 and Q&A 5 regarding your option to join Wisconsin Energy’s Stock Plus Investment Plan following the merger effective date.

Q4: When the Stock Investment Plan is terminated, how will this affect the shares held in my ESOP?

A: The termination of the Stock Investment Plan is separate and distinct from the ESOP, and the termination of the Stock Investment Plan will have no effect on the shares you hold in your ESOP.

Q5: I currently reinvest my dividends to purchase additional shares of Integrys common stock.  Will I have that option with the new company, WEC Energy Group?

A: Similar to the way that you are used to reinvesting your dividends through our Stock Investment Plan, Wisconsin Energy offers their Stock Plus Investment Plan.  The Stock Plus Investment Plan provides a convenient way to purchase WEC stock and reinvest dividends.  You will have the option to join Wisconsin Energy’s Stock Plus Investment Plan.
If you have questions on the Wisconsin Energy Stock Plus Investment Plan, please contact Computershare Shareowner Services at 800-558-9663 for assistance.
Q6: I purchase shares of stock through payroll deduction.  Will WEC’s Stock Plus Investment Plan allow me to purchase company stock through payroll deduction?

A: No.  However, an automatic investment option is available.  Under this option, you may elect to have funds withdrawn from your checking or savings account at a qualified financial institution once a month for investment in the plan as optional cash investments.

Q7: Why did I receive a dividend check for the June 19, 2015 dividend payment?  I am signed up for dividend reinvestment.

A: Under the terms of the merger agreement, the Stock Investment Plan will be terminated effective June 10, 2015, prior to the merger effective date.  Dividend reinvestment occurs through the Stock Investment Plan.  As a result, the June 19, 2015 dividend will be paid in cash to shareholders.
