Hello, as you know, I’m Ward Nye, Chief Executive Officer of Martin Marietta Materials.
I want to take this opportunity to speak directly with you, our colleagues and employees, about a very exciting step we’ve taken.
Martin Marietta has made a public proposal to combine with Vulcan Materials Company. If this transaction is completed, we’ll create a company that will be the leading global aggregates producer – and an enduring American champion.
We believe this is a phenomenal opportunity to bring together two American companies with complementary footprints and assets.
Together, we can create an even stronger company, well positioned to compete now and in the future.
We would have greater scale and efficiencies that will enable us to deliver enhanced products and services to customers.
Financially, the combined company would be one of the strongest in the industry with the ability to make important investments.
As a result, we foresee greater growth opportunities – and value – for virtually everyone associated with our companies.
As you know, these last few years have been challenging for our nation and industry. We have experienced the most trying recession since the Great Depression.
But we should be proud that Martin Marietta has been one of the best performing companies in the industry for a variety of reasons, a major one being each and every one of you — at all levels and throughout this company.
Our disciplined approach to cost management and operational efficiency has enabled us to remain financially stable, invest in our business and continue to deliver a shareholder dividend. Just as important

to our long-term success, is our ability to identify growth opportunities and respond proactively to market dynamics.
As we look to the future, combining Martin Marietta and Vulcan makes excellent industrial and financial sense. We believe it is the best path for the employees and shareholders of both companies and the communities in which we both operate.
It is our hope and expectation that over the long-term, the strategic combination will lead to greater opportunities for advancement and growth for both sets of employees as we merge our cultures and our operations.
The combined company would be headquartered in Raleigh, with a strong presence in Vulcan’s home town of Birmingham, Alabama. The Martin Marietta Board has asked me to continue on as the President and CEO of the combined company, and as part of our proposal Vulcan’s CEO, Don James, would be chairman of the board.
We hope that Vulcan, with the support and encouragement of its shareholders, will negotiate with us to achieve a mutually agreed upon combination of our companies.
We’ve taken a number of steps so that Vulcan shareholders, many of whom are also our shareholders, can send a strong message to their Board that they want our proposal to be fairly and objectively considered.
We’ll keep you posted when there are significant developments. You can also refer to the website that we’ve set up at www.aggregatesleader.com for information about our proposal.
So, what can you do to help us achieve success in this transaction? Stay focused on working safely so we can continue achieving world-class levels of safety and striving for our goal of zero incidents. Stay focused on operational excellence so we can continue performing at the highest level. Your performance is the very foundation supporting this strategic move.
If this transaction doesn’t work out, we’ll continue to be one of the best performing companies in the industry and we will continue to pursue attractive opportunities to grow our business.
We do think a combination with Vulcan is an exceptional opportunity for both companies, and we’re going to do everything we can to make this transaction happen.
Your support will be a great strength for Martin Marietta, and for me personally throughout this process.
As always, I thank you for everything you do for Martin Marietta and please have very safe and productive day.
