18 Shareholder Presentation, March 2012 Vulcan’s Profit Enhancement Plan Adds Significant Value That Belongs to Vulcan Shareholders

19 Shareholder Presentation, March 2012 Vulcan’s Profit Enhancement Plan Creates Significant Value, Which Belongs to Vulcan’s Shareholders . Vulcan’s standalone opportunity is significant: 2011 Restructuring Initiative and Profit Enhancement Plan deliver $155 million of incremental EBITDA — Completed $55 million in savings actions from 2011 restructuring initiatives — Recently-announced Profit Enhancement Plan to realize an additional $100 million in run rate savings by mid 2013 . Vulcan’s Profit Enhancement Plan creates realistic operating efficiencies and cost savings within a credible timeframe, without incurring the costs and risks of a transaction with Martin Marietta — This independently-created value belongs to Vulcan’s shareholders . The Plan is driven by an experienced leadership team that successfully completed Vulcan’s 2011 Restructuring Initiative . Wall Street analysts have applauded the Plan, raising their 2012 EBITDA projections by 15% and share price targets by 25% . Under Martin Marietta’s proposal, our shareholders would realize only some of Martin’s vaguely defined synergies, which confuse “true synergies” with Vulcan’s ongoing cost improvement efforts — Martin Marietta is counting our cost savings as their “synergies”

Developed function-specific plans and identified cross-cutting initiatives that affect multiple functions . Identified additional ways to streamline activities in support functions with the help of the new ERP system

23 Shareholder Presentation, March 2012 Wall Street Research Analysts Agree that Vulcan’s Profit Enhancement Plan Will Create Value for our Shareholders...  Realistic and Achievable Targets . “In our opinion, management’s EBITDA target [$500 MM in FY12E] is realistic and achievable in light of $75 MM in anticipated cost savings...In light of announced cost saving initiatives and potential upside from related productivity enhancements, we believe that VMC has multiple different levers that it can pull in order to achieve its financial targets.” (RBC, 17-Feb-2012) . “...we think VMC has the wherewithal and, more important, the incentive, to hit its target” (Longbow, 17-Feb- 2012) High Impact . “Cost saves make a big difference. VMC is really going after costs, projecting $100MM of savings (in place by mid-2013) on top of the $55MM already put in place.” (Sterne Agee, 16-Feb-2012) . “Big Strides in the Right Direction: Management also announced a slew of new initiatives including another $100 MM round of cost saving measures; $500 MM of non-core asset sales; and the possibility of increasing the dividend.” (RBC, 17-Feb-2012) Increased Operating Leverage . “We like the steps taken to lower costs throughout the operation and improve efficiencies which should increase operating leverage through 2012.” (Morgan Keegan, 17-Feb-2012) . “If VMC is right, we could see a strong bounce in the aggregates margins from the combination of big-time cost cutting and higher volumes.” (Sterne Agee, 16-Feb-2012) Material EBITDA Growth Trajectory . “In our view, the eventual realization of at least $150+MM in annual cost savings should support material EBITDA growth during the next 3 years even in the absence of a volume recovery.” (RBC, 17-Feb-2012) . “Given recently implemented cost savings measures, the company guided to peak EBITDA (including FRK) on 25% less peak volumes. This would imply $1.3B in EBITDA on 220M tons of demand, or a 50% increase from 2011 volume levels of 143M tons. Our normalized volume forecast in 2015 assumes $1B in EBITDA on 180M tons of demand suggesting that VMC’s guidance is largely obtainable.” (Longbow, 17-Feb-2012) Note: See Important Disclosure Notes—Additional Information. Permission to use quotations neither sought nor obtained

24 Shareholder Presentation, March 2012  ...and Have Raised their Earnings Estimates and Price Targets to Reflect the Benefits of the Plan Increased Margin Outlook . “In our opinion, the company’s substantial upside leverage to a recovery has been enhanced by management’s cost saving initiatives and productivity enhancements. Accordingly, we believe that a 6% increase in shipments from FY11A to FY13E would result in EBITDA per ton increasing by 29% from $2.97 to $3.83 during the same period.” (RBC, 17-Feb-2012) Raising Estimates . “We are raising our estimates for Vulcan to reflect the benefits of its cost savings initiatives that are expected to carry into 2012, 2013 and beyond...Our EBITDA assumptions for 2012 and 2013 are now $500.5 million and $564.0 million compared to $416.5 million and $556.0 million, respectively.” (D.A. Davidson, 17-Feb-2012) . “Following these results and a recent meeting with management, we are raising our 2012 EBITDA from $409 million to $466 million ($0.61 EPS loss to a $0.35 loss), reflecting nascent signs of momentum in VMC’s core aggregates business (volume up 3%, price up 1% in 4Q) and cost cutting initiatives underway. (KeyBanc, 21-Feb- 2012) . “As a result of the better-than-expected 4Q report as well as the company’s cost savings initiatives and a slightly better macro outlook, we are raising our estimates on VMC. For FY2012, our EPS estimate goes from ($0.67) to ($0.26) and our EBITDA estimate goes from $409MM to $484MM. For FY2013, our EPS estimate goes from $0.01 to $0.62 and our EBITDA estimate goes from $561MM to $659MM.” (Sterne Agee, 16-Feb-2012) Higher Price Targets . “Last Thursday (16 February) Vulcan announced better than expected Q4 results, a $100m Profit Enhancement Program which will fully contribute in 2014, and that it was targeting $500m of divestments by the end of 2012. In our view this significantly increases the value of Vulcan shares. We are therefore increasing our mid-cycle based price target from $51 to $61 and retaining our Buy rating.” (Jefferies, 20-Feb-2012) Note: See Important Disclosure Notes—Additional Information.

32 Shareholder Presentation, March 2012 Martin Marietta’s Claims are Self-Serving and Ignore the Facts MLM’s Claims The Facts “Shareholders will benefit from the skills and experience of the respected Martin Marietta management team.”(1) • Martin Marietta lacks any relevant experience acquiring and integrating public companies. Martin Marietta also lacks experience integrating any company of Vulcan’s size. In fact, the largest acquisition the company has ever undertaken was less than $300 million, which occurred prior to Ward Nye joining Martin Marietta. • Under current management’s leadership, Martin Marietta has underperformed the industry in price growth • Vulcan’s management team has created a substantially more profitable aggregates business “[Vulcan says the] DOJ will follow a mechanistic radius approach in determining which assets will be required to be divested in a combination... This is nothing more than scare tactics, with no basis in reality.” (2) • In its IR presentation dated January 5, 2012, Vulcan illustrated the amount of aggregates transported from Vulcan facilities within radii of 20, 40, 60 miles of a Martin Marietta facility • The second request from DOJ was fully consistent with Vulcan’s illustrations, which clearly was not a scare tactic • In fact, the DOJ request was more comprehensive than the request received by Vulcan in the Florida Rock deal, reflecting a substantially greater degree of overlapping operations and potential divestitures • DOJ Request: • The amount of aggregates shipped from Vulcan facilities to locations within distances of 20 to beyond 200 miles of a Martin Marietta facility • The amount of asphalt concrete shipped from Vulcan facilities to locations within distances of 10 to beyond 60 miles of a Martin Marietta facility • The amount of ready mix concrete shipped from Vulcan facilities to locations within distances of 5 to beyond 30 miles of a Martin Marietta facility In announcing MLM’s timing agreement with the DOJ, MLM said, “...the HSR review process relating to our proposed combination with Vulcan can be concluded on a timely basis.”(3) • The HSR review process for the proposed combination will be anything but timely. Timing agreements typically extend the review period by three to four months. Martin Marietta’s timing agreement extends the review period by seven months (DOJ often seeks to push this date back even further), and includes the provision that “Martin Marietta will not seek to close the transaction prior to mid-August” if a consent order is not reached. (3) • Timing agreements sometimes obligate the DOJ to have its final recommendation done by a certain date, but Martin Marietta only states that the DOJ commits to “discuss resolution of any antitrust concerns in an effort to reach agreement.” (3) • “This is a long time horizon for a timing agreement, providing more evidence that Vulcan officials have been right to warn shareholders that Martin's bid faces serious antitrust issues and, even if they can be worked out in a way that still preserves the value of the transaction, will take a long time to resolve.”- The Deal, Feb. 14, 2012(4) (1) MLM’s S-4 filed on December 12, 2011 (2) MLM January 10, 2012 Transcript pg. 5 (3) MLM’s Press Release Issued on February 14, 2012 (4) See Important Disclosure Notes – Additional Information.

Thus, they should not be considered as an alternative to any earnings measure defined by GAAP. We present these metrics for the convenience of investment professionals who use such metrics in their analysis, and for shareholders who need to understand the metrics we use to assess performance. The investment community often uses these metrics as indicators of a company's ability to incur and service debt. We use cash gross profit, EBITDA and other such measures to assess the operating performance of our various business units and the consolidated company. We do not use these metrics as a measure to allocate resources or as liquidity measures. Reconciliations of these metrics to their nearest GAAP measures are presented below:
