United Rentals VP Talking Points

THE NEWS

•

On December 16, 2011, United Rentals announced that it has reached an agreement to acquire RSC Holdings in a cash-and-stock transaction currently valued at $18.00 per share, or a total enterprise value of $4.2 billion, including $2.3 billion of net debt. The deal is expected to close in the first half of 2012, after receiving the necessary approvals.

•

Two respected businesses will be combined to create a new, best-in-class equipment rental company. It is an unprecedented milestone in the equipment rental industry.

•

By joining forces, United Rentals and RSC are bringing together a wealth of best practices and talent. The two companies have a lot of respect for each other. They share a similar philosophy of customer service, safety and commitment to excellence.

•

RSC is very well regarded for having a well-managed fleet, extensive customer support resources and a strong geographic presence. Currently, RSC services the industrial and construction markets with $2.7 billion of equipment and approximately 440 rental locations. They primarily operate in the United States, but have a presence in Canada as well.

THE WHY

•

The deal creates the leading North American equipment rental company, with greater scale, stronger growth prospects and more opportunity for operational efficiencies.

•

The new United Rentals will have a broad geographic footprint, with nearly 1,000 branches across the U.S. and Canada, and the largest, most versatile fleet in the industry.

•

The expansion should accelerate United Rentals’ growth with larger customers who operate nationally and multi-regionally.

•

RSC’s industrial base, added to our own, will make it easier to manage the business for less volatility in future cycles.

•

The timing is ideal:

	•		We should receive even more benefit from the trend toward rental penetration.
	•		Our construction end markets are projected to begin a modest recovery.

NEXT STEPS

•

It is business as usual between now and the closing. For now, nothing changes.

•

Our strategy for capturing business is still exactly the same. Sales calls, quotations and other customer situations should be handled the same way they are handled now, according to our company’s objectives for rate management, fleet management, customer service and margin improvement.

•

There will be no immediate changes to employee responsibilities. The top priority is to continue to provide customers with consistent, seamless support of the highest quality. Ultimately, we believe that the deal will translate into significant opportunities for employees of both companies.

•

Salaries and benefits will remain unchanged through December 31, 2012. Whatever you elected for 2012 will remain in effect for the full year. The company still intends to do a merit increase in 2012.

•

For our salespeople, there will be no change to the incentives, commissions and bonus structure we originally intended for 2012, although the sales opportunities themselves may change during the course of the year. The 2012 structure will be communicated in early January, as it is each year.

•

Both United Rentals and RSC provide strong and very similar compensation, healthcare and employee benefit programs. Our company will be very careful in selecting the best programs for 2013 forward, and will communicate on this topic so employees are well aware of any future developments.

•

At this early date, there is no timeline for future decisions on how merging of the operations may affect individual employees or branches. As soon as a timeline is available, you’ll hear about it.

•

Our company has a proven track record of successfully integrating businesses by identifying the best practices and talents of the companies we acquire. Obviously there is more overlap of operations in some areas than others, and those situations will be looked at carefully on a one-by-one basis. Certain areas may have no changes at all. You can be assured that no wholesale decisions will be made. United Rentals values each of its employees and will use the fairest possible process in cases where selections must be made.

•

Management will do its best to keep employees informed as much as possible every step of the way. We already have a culture of openness and strong channels of communication. That’s not going to change. If anything, these channels will be used more frequently in anticipation of our expanded employee base.

•

Customers will be watching us closely during the transition. We need to meet every expectation. Our employees will play a critical role in ensuring the success of this venture.
