DENVER & MONTREAL--(BUSINESS WIRE)--May 3, 2011--Molson Coors Brewing Company (NYSE: TAP; TSX) today reported 4.4 percent higher net sales, a 33.2 percent increase in net income from continuing operations, and a 17.1 percent increase in underlying after-tax income for the first quarter 2011, driven by positive pricing and continued cost reductions.

Molson Coors president and chief executive officer Peter Swinburn said, “In the first quarter, our company increased underlying after-tax earnings 17 percent and expanded margins significantly, despite continuing challenges from sluggish core-market economies, weak industry volume and accelerating global commodity inflation. While we faced particularly difficult volume comparisons in Canada as we cycled last year’s Vancouver Winter Olympics, our volume trends in the U.S., U.K. and International improved versus recent quarters. Equally important, the strength of our brands drove positive pricing and net sales growth across our company. We also continued to exceed our cost reduction goals, which provided resources to invest in our brands, grow earnings and generate cash. Continuing to deliver strong earnings growth in the face of substantial headwinds bodes well for our ability to perform even better when economic and industry conditions improve.

“These results reflect progress against our three growth pillars of maximizing the value of our core markets, expanding our exposure to emerging markets, and taking advantage of smart M&A opportunities. We have a strong team focused on growing this business, realizing our vision of becoming a top global brewer in profitability, and delivering long-term value to our shareholders.”

Cost Savings Highlights

In the first quarter 2011, the Company delivered $10 million of Resources for Growth Two (RFG2) cost reductions.

MillerCoors achieved $23 million in synergies in the quarter. MillerCoors has delivered $528 million in synergies since beginning operations on July 1, 2008, surpassing the original commitment to deliver $500 million by June 30, 2011. MillerCoors also delivered incremental cost savings of $6 million in the quarter. Molson Coors’ 42 percent share of these synergies and incremental cost savings was $12 million in the quarter.

Effective Tax Rate

The Company’s first quarter effective tax rate was 16 percent on a reported basis and 17 percent on an underlying basis. The Company estimates that its full-year 2011 effective tax rate will be in the range of 17 percent to 21 percent on an underlying basis, assuming no further changes in tax laws.

Pension Update

The Company now anticipates contributing about $60 million of cash to its defined-benefit pension plans this year, including its portion of MillerCoors and Canada joint venture contributions, down from $386 million in 2010. Total-company pension expense is expected to be approximately $60 million in 2011, $18 million lower than last year.

1^st Quarter Business Segment Results

Following are the Company’s first quarter 2011 results by business segment:

Canada Business

Canada underlying pretax income in local currency decreased 7.7 percent⁽³⁾. Increased net pricing and overhead reductions were more than offset by mid-single-digit volume declines and input inflation. In U.S. dollars, Canada underlying earnings decreased 3.2 percent to $54.4 million in the quarter, which reflects a $1 million benefit from a 6 percent year-over-year strengthening in the Canadian dollar versus the U.S. dollar.

Canada sales-to-retail (STRs) for the quarter decreased 6.9 percent. Continued volume gains from our new brands, including the expansion of Molson M into Ontario and Western Canada, Keystone Lager into Ontario and Molson Canadian 67 into Quebec, were more than offset by declines in established brands. These declines were driven by the cycling of last year’s Winter Olympics, continued economic pressures and additional competitive promotional activity. These factors resulted in a mid-single-digit STR decline for Coors Light and a low-double-digit decline for Molson Canadian.

Canadian beer industry STRs decreased an estimated 5.8 percent in the first quarter, driven by the same factors.

Canada sales volume was 1.7 million hectoliters in the quarter, down 5.9 percent. Net sales per hectoliter increased 1.8 percent in local currency, driven by net pricing on our key brands that delivered a 3 percent increase, approximately one-third of which was offset by sales mix.

Cost of goods sold per hectoliter increased 3.1 percent in local currency in the quarter, driven by a 3 percent increase related to higher commodity, fuel and distribution costs, more than a third of which was offset by cost savings. In addition, fixed cost deleverage related to lower volume drove a 1.5 percent increase.

Marketing, general and administrative expenses decreased 4.9 percent in local currency due to lower overhead expenses and the release of an indirect tax reserve.

United States Business (MillerCoors)⁽⁴⁾

Molson Coors underlying U.S. segment pretax income increased 7.6 percent to $101.8 million in the quarter, due to strong MillerCoors results.

MillerCoors Operating and Financial Highlights

MillerCoors underlying net income for the quarter, excluding special items, increased 8.7 percent to $236 million, driven by positive pricing, favorable brand mix, continued strong cost management, and a one-time payment from a third party.

MillerCoors domestic STRs declined 1.4 percent due to continued industry headwinds. This represents an improved STR trend versus the previous five quarters. Domestic sales-to-wholesalers (STWs) declined 2.5 percent.

Domestic net revenue per hectoliter increased 2.1 percent, driven primarily by front-line pricing and brand mix, partially offset by increased costs associated with planned cross-merchandising programs. Total company net revenue per hectoliter, including contract brewing and company-owned distributor sales, increased 2.6 percent.

Cost of goods sold per hectoliter increased 1.2 percent, due to higher freight and fuel costs, which were partially offset by synergies and other cost savings.

Marketing, general and administrative costs decreased 1.3 percent, due to the one-time receipt of $14 million from a third party.

Depreciation and amortization expenses in the quarter were $71.5 million, and additions to tangible and intangible assets totaled $89.2 million.

United Kingdom Business

U.K. underlying pretax income more than doubled to $4.6 million in the quarter, driven by a decrease in defined-benefit pension expense and higher pricing, partly offset by lower volumes and higher cost of goods sold. Although the British Pound appreciated approximately 4 percent versus the U.S. dollar, this change had no significant effect on U.K. pretax income.

U.K. owned-brand STRs decreased 1.6 percent, adversely impacted by Easter moving into the second quarter 2011 versus the first quarter in 2010, partly offset by the benefit of adding the Modelo and Sharp’s brands this year. Market share increased slightly in the quarter, with total U.K. beer industry volume decreasing approximately 4 percent.

Net sales per hectoliter of owned brands increased 10 percent in local currency, driven by positive pricing and sales mix in the quarter, with about half the change due to the addition of the Modelo brands.

Cost of goods sold per hectoliter of owned brands increased 13 percent in local currency, with two-thirds of the change due to the addition of the Modelo brands, along with higher-cost channel mix, fixed-cost deleverage from lower volumes, and input cost inflation, partly offset by lower pension expense.

Marketing, general and administrative expense was unchanged in local currency, due to implementation costs for a new UK enterprise information system, which was offset by $3.8 million lower pension expense this year.

International and Corporate

The underlying pretax loss for International and Corporate was $62.3 million in the quarter, a 5.3 percent decrease. Approximately $7.5 million of the loss related to the International group, with the balance driven by Corporate MG&A and interest expense.

The Company’s International business grew volume more than 45 percent, driven by the addition of the Si’hai brands in China and growth of Coors Light in Latin America and China. Marketing, general and administrative expense for International was $15.2 million in the quarter, an increase of $3.6 million, due to increased marketing, sales and other investments in our priority international markets.

Corporate marketing, general and administrative expense was $28.3 million in the quarter, a decrease of $5.1 million, driven by lower expense this year related to implementing cost-savings initiatives.

Corporate net interest expense was $28.3 million, an increase of $2.1 million compared to a year ago, due primarily to foreign currency movements.

In the quarter, Corporate other income of $2.3 million was driven by foreign currency movements and a gain on the settlement of Foster’s total-return swaps and related financial instruments.

Special and Other Non-Core Items

The following special and other non-core items have been excluded from underlying pretax earnings.

During the quarter, the Company had special items that netted to zero, composed primarily of Canadian early retirement incentive expenses of $2.7 million, largely offset by the release of a non-income-related tax reserve of $2.5 million in the U.K.

Other non-core items totaled a $0.6 million net pretax gain, primarily due to a $0.8 million non-core gain related to the Foster’s total-return swaps and related financial instruments, partially offset by a $0.2 million environmental reserve.

During the quarter, MillerCoors reported special charges totaling $1.4 million, primarily related to relocation costs associated with the joint venture integration. This equates to $0.6 million at Molson Coors’ 42 percent economic ownership share.

⁽²⁾ The Company calculates non-GAAP underlying income by excluding special and other non-core items from the nearest U.S. GAAP earnings measure, net income from continuing operations attributable to MCBC. To calculate underlying income in the first quarter of 2011, the Company excluded non-core gains, losses and expenses, particularly related to changes in the value of the Company’s Foster’s cash-settled total-return swap, and an environmental reserve, (as well as special items netting to zero pretax). For further details, please see the section “Special and Other Non-Core Items”, along with tables for reconciliations to the nearest U.S. GAAP measures.

⁽³⁾ Note that local currency results for Canada exclude the $1.7 million negative impact of foreign currency hedges in Other (Expense) Income, net, in the first quarter of 2011, and a $1.4 million negative impact in the first quarter of 2010, as it is meaningful to consider those hedges only when viewing the Canada segment in U.S. dollars.

Reconciliations to Nearest U.S. GAAP Measures

Pretax and after-tax underlying income should be viewed as a supplement to, not a substitute for, our results of operations presented on the basis of accounting principles generally accepted in the United States. Our management uses underlying income as a measure of operating performance to assist in comparing performance from period to period on a consistent basis; as a measure for planning and forecasting overall expectations and for evaluating actual results against such expectations; and in communications with the board of directors, stockholders, analysts and investors concerning our financial performance. We believe that underlying income performance is used by and is useful to investors and other users of our financial statements in evaluating our operating performance because it provides them with an additional tool to evaluate our performance without regard to items such as special items, which can vary substantially from company to company depending upon accounting methods and book value of assets and capital structure.
