Associate Q&A

1. Why are we doing this?

I’ve been preparing you for this idea for a number of months now – even before we began talking with BNC Bank. Just in case you missed it, review my blog on our growth strategy. I specifically laid out the targets for where we want to go (Charlotte, Raleigh, Charleston, Atlanta, etc.) and how we plan to get there.

This merger represents a huge opportunity for our company to expand into six of the nine markets we targeted. I want to be sure you understand where we are headed as a company. While the vision is expanding, the values and strategy remain the same. We want to:

• Create a cool company filled with associates who share our values.

• Take Pinnacle’s unique brand and excellent client experience to other urban, fast-growing markets in the Southeast.

• Ensure our independence and reward our associates personally by producing a strong shareholder return.

2. What’s the next step? When will the two companies combine?

Contingent on, among other things, regulatory and shareholder approvals, we anticipate closing the merger in the third quarter of 2017. That will technically complete the financial combination of the two firms.

Based on these projections, the system conversion would take place in 4Q 2017 or early 2018. It is at the time of the system conversion that BNC’s brand, signage, etc. will become Pinnacle’s.

3. What does this do to our 2017 incentive plan?

There will be no impact to our 2017 incentive plan. Any non-recurring expenses associated with the merger will be isolated. We’ll talk more at the all-associate meeting on Tuesday.

4. Will this result in any changes to Pinnacle’s compensation or benefits plans?

The merger will have no impact on Pinnacle’s compensation or incentive plans. In addition, you should not expect any degradation or major changes to your existing benefit plans.

5. Will there be any office closures?

There are none planned in our legacy markets. BNC leadership will review the branch distribution in their markets and make decisions. We anticipate some office closures will occur as a result of their review.

6. Will any current Pinnacle associates be eliminated as a result of the consolidation?

No.    

7. What are Pinnacle’s plans for adding infrastructure to support this rapid growth in staff?

With this acquisition we are adding nearly twice as many offices, two-thirds the assets and nearly doubling the associate base.

I recognize this is a lot of growth. One of our priorities is to increase profitability and productivity. We recognize that to achieve the growth we desire, we will need to add associates in operational areas to support the growth. We will be sure to approach that thoughtfully and work with leaders to understand the impacts.

8. How much internal focus will integration require?

Hugh Queener will once again lead an implementation team in the complete planning and execution of this project. He will name a cross-functional group of Pinnacle associates to participate on that team.

While this will be a monumental undertaking for our operating staff, it is expected to have only modest impact on our client contact associates, enabling the continued rapid growth of our companies. I hope you’ve experienced that with our other mergers.

Areas like systems support, operations, training, communications and others will be heavily involved in ensuring the integration is a success. Please be mindful of this as you interact with these teams. Remember, we all win together and lose together. Support your fellow associates and offer your partnership to get this done.

9. Do BNC and Pinnacle share the same credit discipline?

Like Pinnacle, BNC has strong credit quality and client selection. We expect the integration of our credit cultures to be relatively smooth.

10. How will the firm’s leadership be affected by the merger?

One of the differentiating aspects of Pinnacle’s culture has been our flat organizational structure and access to leadership. To that end, key leaders at BNC Bank, including CEO Rick Callicutt and CFO David Spencer, will continue with the combined company with primary responsibility for the Carolinas and Virginia. We hope to retain key leaders in all BNC markets.

There are a few changes we will make to support a larger organization. There is minimum impact to associates. Here’s what it looks like:

• My role will shift somewhat. When we did our latest book club – The One Thing – I asked each book club leader to poll their attendees on what they thought my “one thing” should be. As always there is never just one answer, but I could boil all the answers down into one key function – guiding the strategy, mission, vision and values for our company. In order to do this across a much larger organization, I will have to be somewhat less involved in managing day-to-day activities in each market and depend on key leaders.

• Rob McCabe will lead the Tennessee market. Rob has agreed to assume leadership for Tennessee. This means that market leaders in Tennessee will report to Rob.

• Rick Callicutt will lead the Carolinas and Virginia. Rick is a strong leader with a great track record for performance. I’m confident in his ability to lead his team in executing the Pinnacle strategy and integrating the culture in his markets.

• Key functions will continue to support the company as a whole including finance, operations, human resources, etc.

11. As we get bigger and more spread out, will we have to stop doing some of the things that have become Pinnacle traditions – like the summer picnic or the anniversary party?

Several of us have already been thinking about how we manage these things across a larger organization. I hope to release our 2017 calendar of events soon. I anticipate we will have several events each year within each market (picnic, baseball games, etc.) as well as an opportunity for everyone in the market to get together and celebrate (anniversary party). We will also consider what a company-wide event might entail.

It will likely be a challenge to get associates from Charleston together with associates from Memphis. However, we will look for opportunities to engage people across markets in getting to know one another better.

Ultimately, we remain committed to the fun and celebratory environment that we have built.
