Email from Mark Ruelle to all Westar employees

Everyone:

As we mentioned last week, with the bidding process behind us, we are able to keep you more up to date on the transaction in which Great Plains Energy will acquire Westar. For clarification, Great Plains owns KCP&L. We’ll be using these two names interchangeably as we move forward, as Great Plains is just the holding company for KCPL, which is essentially their entire business.

I’m hopeful we’ve answered many of your questions in the last few days. And I know that as you have time to reflect or visit with friends and families, new questions emerge. Next week, we plan to launch a central site on ePower for updates on merger-related items. While we’ve said it’s “business as usual,” we also know that you’re interested in progress and how this all affects you. We may not have all the answers right now, but we want to keep you updated and share what we can as soon as we can. Watch for that link in the next few days.

Until then, here are a few questions Terry Bassham, Chairman, President and CEO of Great Plains, and I received when we visited with many of you last week.

The question on everyone’s mind is how does the announcement affect me and my job? As we said at all meetings last week, we believe natural attrition and retirements (which equal about five percent turnover annually at each company) will allow us to achieve the cost savings needed to make the new, larger company successful. With a company this size, that will add up to 10s and even hundreds of millions of dollars over time. Yes, some of those cost savings will come through staffing changes or consolidations. It’s too early to know specifics – that will come with the integration planning during the next several months. KCP&L is proud of its record of not having resorted to layoffs in the past to meet its objectives, and I know they’d like to sustain that practice. However, we all know that life provides few guarantees, So, for additional assurance we negotiated for them to adopt our existing non-union severance plan, and even expand it to fill in some gaps, such as might exist with employees who have short tenure with Westar. (For employees covered by the collective bargaining agreement, of course, that contract still holds.) It’s a formula based on your specific circumstances, so it would be different for each employee, but, for example would also include any prorated portions of STI as well as value for medical, dental, and visions plans. Our HR team is finalizing the plan and we will be circulating more details soon.

A great question asked was “what’s the name of the company I’ll work for?” I’m paraphrasing of course, but Terry talked about the need to have the combined company operate under one name – one brand. That way, customers in Wichita, Salina, Kansas City, Topeka or Marshall, Missouri, have confidence in seeing the same name on our vehicles, hardhats, etc., and knowing it stands for exceptional customer service, safety, and reliability. Equally important is that employees feel part of one team. What that name is hasn’t been determined, and will be part of the integration process.

Perhaps you’ve also read headlines about shareholder lawsuits. It’s not unusual for legal firms, many of whom specialize in class-action litigation, to claim terms are “unfair” to shareholders. We believe these lawsuits are without merit, but, unfortunately, they are part of the process in most business transactions. We negotiated terms very good for shareholders, and will manage the lawsuits just as we’ll manage our path forward to approvals.

Earlier today, the Missouri Public Service Commission met to decide whether they will exert jurisdiction over the transaction, similar to what we know exists in Kansas already. They put off the decision for a few weeks. Should they decide they have jurisdiction, then that body’s approval, too, would be required. Worse case is just another regulatory hurdle to manage.

When one company buys another, sometimes analysts like one side better than the other. Nobody expects everyone to be happy – so don’t be surprised to see reports on financial web and news sites that question the value, the approach and the strategy. This, too, is normal and part of the process. Both investor relations teams continually visit with the financial community so questions are answered and terms are better understood. It’s also quite normal for the stock price of the acquirer (Great Plains ticker symbol: GXP) to trade down after an acquisition announcement. It also makes sense for Westar to trade higher, in anticipating of getting a premium when the deal closes. Both have happened as expected.

There are several milestones ahead, including integration planning, which – at a high level – identifies our combined differences, similarities and best approaches to adopt for the new company. The goal is to make us better. John Bridson, SVP, Generation and Power Marketing, will serve as Westar’s integration co-lead, working closely with KCP&L’s co-lead, Steven P. Busser, Vice President, Risk Management and Controller. John is an exceptional choice given his existing working relationship with KCP&L with our jointly owned power plants (LaCygne, Wolf Creek and Jeffrey). John epitomizes our core values, and will continue leading the Generation and Power Marketing groups in addition to the integration work ahead. We anticipate integration activities will kick off in earnest following the July 4th holiday. We’ve already heard from many employees who want to serve on integration committees and we thank you for your interest and engagement. In fact, we anticipate we’ll have more employees raise their hands for integration than what is required. So if you’re not selected, please don’t think we don’t want your ideas. And we will need everyone’s continued focus on delivering the safe, reliable electricity for our customers with a “business as usual” approach until our merger is complete. My thanks and congratulations to John for accepting this important assignment for our future.

As I said last week, I again thank you for all you’re doing to stay focused on keeping the lights on. Summer weather will heat up during the next few days, so please stay safe and hydrated.

Sincerely,

Mark
