PRESS RELEASE

MWV Reports Fourth Quarter and Full-Year 2013 Results

Fourth Quarter Highlights:

RICHMOND, Va., January 29, 2014—MeadWestvaco Corporation (NYSE: MWV), a global leader in packaging and packaging solutions, reported increased sales and earnings for the fourth quarter of 2013 on a continuing operations basis compared to the prior year. Growth in targeted packaging and specialty chemicals markets, as well as improved pricing and operational performance, drove the better results. The company continued to gain share with food and beverage brand owners and grew volumes in higher value dispensing solutions, including gains in medical plastics, fragrance pumps and personal care dispensers. Sales and earnings growth in the Industrial segment was driven by higher pricing and the sustained achievement of targeted productivity goals, while the Specialty Chemicals segment continued to see steady growth across its offerings for the global asphalt, oilfield and activated carbon markets.

“The revenue and earnings improvement we saw this quarter is the result of solid commercial and operational execution across each of our businesses,” said John A. Luke, Jr., chairman and chief executive officer, MWV. “Our growth strategy has generated momentum in targeted packaging and specialty chemicals markets. We are now focused on accelerating profitability, with actions designed to reduce complexity, realign our corporate infrastructure and focus participation strategies and investments on the highest return opportunities. We are confident that we will see great progress in each of these areas, leading to higher earnings and cash flow this year.”

Fourth Quarter and Full-Year Comparison

Sales from continuing operations in the fourth quarter of 2013 were $1.32 billion, up 3 percent from 2012. Income from continuing operations attributable to the company in the fourth quarter of 2013 was $213 million or $1.18 per share, compared to a loss of $5 million or $0.02 per share in 2012.

Fourth Quarter Segment Results

Following is a summary of fourth quarter 2013 results by business segment. All comparisons of the results for the fourth quarter of 2013 are with the fourth quarter of 2012 on a continuing operations basis.

Food & Beverage

In the Food & Beverage segment, sales were $748 million in the fourth quarter of 2013 compared to $744 million in the fourth quarter of 2012. Profit was $61 million in the fourth quarter of 2013 compared to $53 million in the fourth quarter of 2012.

Modest sales growth was led by gains in targeted food and tobacco markets. Food packaging sales were driven by gains with major brand owners in a range of applications, including frozen food and club store packaging and strong gains in liquid packaging. Tobacco paperboard sales were strong across all regions. Beverage sales were down modestly, with strong sales in emerging markets and continued gains with large strategic soft drink and beer customers offset by declines in market volumes across the developed markets.

Profit performance in the fourth quarter of 2013 versus the prior year was largely driven by volume growth, improved operating productivity and deflation in energy and certain raw materials. Compared to the third quarter of 2013, the segment realized solid pricing and product mix gains.

Home, Health & Beauty

In the Home, Health & Beauty segment, sales were $182 million in the fourth quarter of 2013 compared to $180 million in the fourth quarter of 2012. Profit was $4 million in the fourth quarter of 2013 compared to break-even results in the fourth quarter of 2012. The 2013 results include a $3 million charge related to certain asset write-downs; earnings for the segment were $7 million excluding this adjustment.

The segment had strong gains in higher value home and garden, beauty and skin care, fragrance, and medical dispensing solutions across all regions. Growth in these areas was partially offset by the exit of the Brazilian folding carton business at the end of the third quarter, as the company repurposes this facility. The repurposing of the Brazilian business is expected to be largely completed in the first quarter of 2014. In the fourth quarter of 2013, sales of the segment’s dispensing solutions in Brazil grew 41 percent. As previously announced, the company is also continuing to pursue an exit from the beauty and personal care folding carton operation in Europe through a sale of the business.

Profit performance reflects volume growth in targeted dispensing markets and improved operating productivity. These gains were partially offset by wage and input cost inflation (plastic resin), as well as costs related to the planned exits of the beauty and personal care folding carton businesses in Europe and Brazil. In the fourth quarter, costs for these actions totaled $2 million.

Industrial

In the Industrial segment, sales were $146 million in the fourth quarter of 2013 compared to $118 million in the fourth quarter of 2012. Profit was $18 million in the fourth quarter of 2013 compared to $9 million in the fourth quarter of 2012.

Overall sales growth was driven by price improvement across targeted Brazilian packaging markets and revenue benefits from the addition of the industrial packaging materials business in India, Ruby Macons. During the quarter, the segment continued to realize increased prices in the Brazilian market to offset labor and input cost inflation. Overall volumes in Brazil were up modestly, as gains in high-quality paper sales more than offset lower corrugated box sales. Corrugated box sales declined due to pricing actions the segment took to offset inflation and the sale of the Feira de Santana box plant in the third quarter of 2013. Sales were also impacted by unfavorable foreign currency exchange.

Profit growth primarily reflects increased pricing, as well as significantly improved productivity in the Brazilian operation. In the fourth quarter, the segment consistently ran its expanded Brazilian operation at designed capacity levels, resulting in improved fixed cost absorption and the elimination of third-party paper purchases in its corrugated box operations. These benefits were partially offset by wage and input cost inflation, unfavorable foreign currency exchange, as well as by the absence of certain one-time, value-added tax items that benefited the fourth quarter of 2012.

Specialty Chemicals

In the Specialty Chemicals segment, sales were $234 million in the fourth quarter of 2013 compared to $232 million in the fourth quarter of 2012. Profit was $53 million in the fourth quarter of 2013 compared to $42 million in the fourth quarter of 2012.

The sales increase was led by solid volume growth in targeted pine chemicals markets and revenue benefits from the addition of the acquired Brazilian pine chemicals business. The segment continued to penetrate the higher value pine chemicals end markets and had solid volumes in asphalt, publication inks and oilfield chemicals. Carbon technologies volumes increased as global automobile manufacturers continued to increase production in response to strong global demand. These gains were partially offset by lower pricing in more standard product lines and unfavorable foreign currency exchange.

Profit performance mainly reflects improved operating productivity. Solid volume levels across targeted pine chemicals and carbon solutions, lower maintenance expense and contributions from operational excellence initiatives drove the productivity improvement. Segment profit also benefited from deflation in energy and contribution from the acquired Brazilian business. Earnings also benefited from nonrecurring gains related to certain insurance settlements. These benefits were partially offset by lower pricing in more standard product lines and unfavorable foreign currency exchange.

Community Development and Land Management

With the successful completion of the sale of the company’s forestland assets to Plum Creek Timber Company, Inc., the Community Development and Land Management segment’s principal activities are now focused on maximizing the value of the remaining 109,000 development acres located in the Charleston, S.C. area. As such, the results of the segment currently reflect the operating expenses related to the ramp-up of the development business.

Sales on a continuing operations basis for the Community Development and Land Management segment were $6 million in both the fourth quarter of 2013 and 2012. A loss of $4 million was reported in the fourth quarter of 2013 compared to a loss of $3 million in the fourth quarter of 2012.

Actions to Accelerate Earnings and Cash Flow Improvement

The company recently announced a new program to generate increased earnings and cash flow. The program will deliver annual pretax savings of $100 to $125 million by the end of 2015, with at least $75 million to be realized in 2014. Free cash flow (cash flow after capital expenditures) also will increase by at least $100 million in 2014 from higher after-tax earnings and a $50 million reduction in capital expenditures to approximately $350 million. Key elements of the margin improvement program include:

Other Items

On December 6, 2013, the sale of the company’s forestry and certain minerals-related businesses was completed, resulting in the recognition of a pretax gain of $780 million. The current and prior year earnings of these businesses, as well as the gain, are presented as a discontinued operation on an after-tax basis. These businesses were previously reported within the Community Development and Land Management segment.

During the fourth quarter of 2013, the company used $131 million of the proceeds from the forestland sale to repurchase approximately 3.75 million shares of common stock. Also as part of the use of the forestland sale proceeds, the company repaid $210 million of indebtedness.

Savings associated with the company’s cost reduction initiative announced in April 2013 were $43 million for full-year 2013. The company remains on track to achieve $75 million in cumulative savings from this initiative by the end of 2014. These savings are incremental to the $75 million of savings to be delivered in 2014 from the company’s new margin improvement program.

In the fourth quarter of 2013, total pretax input costs of energy, raw materials and freight were flat compared to the fourth quarter of 2012 on a continuing operations basis.

In the fourth quarter of 2013, the pretax impact on earnings from foreign currency exchange was flat compared to the fourth quarter of 2012 on a continuing operations basis.

Cash flow provided by operating activities from continuing operations improved to $194 million in the fourth quarter of 2013 compared to $178 million in the fourth quarter of 2012. Cash flow provided by operating activities from continuing operations improved to $358 million for full-year 2013 compared to $220 million for full-year 2012.

Capital spending from continuing operations declined to $169 million in the fourth quarter of 2013 compared to $172 million in the fourth quarter of 2012. Capital spending from continuing operations declined to $506 million for full-year 2013 compared to $654 million for full-year 2012. These declines primarily reflect lower investment related to the company’s expansion in Brazil, which was substantially completed in 2012.

Capital spending is expected to be approximately $350 million in 2014.

The company’s U.S. qualified retirement plans remain overfunded, and management does not anticipate any required regulatory funding contributions to such plans in the foreseeable future.

Outlook

For the first quarter of 2014, earnings excluding special items are expected to be well above last year. The principal factors driving the expected improvement are:
