BOSTON BEER REPORTS

FIRST QUARTER 2014 RESULTS

BOSTON, MA (4/30/14) — The Boston Beer Company, Inc. (NYSE: SAM) reported first quarter 2014 net revenue of $183.8 million, an increase of $47.9 million, or 35%, over the same period last year, mainly due to core shipment growth of 32%. Net income for the first quarter was $8.3 million, or $0.62 per diluted share, an increase of $1.4 million, or $0.11 per diluted share, from the first quarter of 2013. This increase was primarily due to shipment increases, partially offset by increased investments in advertising, promotional and selling expenses and the impact of a favorable federal income tax settlement of $0.06 per diluted share in the first quarter of 2013.

Highlights of this release include:

Jim Koch, Chairman and Founder of the Company, commented, “I am pleased that The Boston Beer Company achieved record depletions in the quarter and that Samuel Adams Boston Lager, our flagship beer, has continued to grow as we celebrate our 30^th anniversary. In the first quarter, we introduced our new spring seasonal, Samuel Adams Cold Snap and I was excited that Cold Snap was well received by drinkers, retailers and wholesalers. Late in the first quarter, we had a smooth transition from Cold Snap to our Summer Seasonal, Samuel Adams Summer Ale, now in its nineteenth year and still one of my favorites. During the quarter, we initiated our national rollout of Samuel Adams Rebel IPA, a West Coast style IPA brewed with hops from the Pacific Northwest. It

continues to receive great support from distributors and on and off-premise retailers. I am particularly pleased with the early success of Rebel IPA that we believe three months into our national launch is already among the top three selling IPAs according to off-premise scan data, and we are still building distribution. We are happy with the health of our brand portfolio and remain positive about the future of craft beer.”

Martin Roper, the Company’s President and CEO stated; “In the first quarter, our depletions growth benefited from the strength in our Samuel Adams, Angry Orchard and Twisted Tea brands. The Samuel Adams brand benefited from our 30^th Anniversary celebration, the rollout of Rebel IPA and the strength of our Seasonal beers. Our brands also benefited from increased brand support, including increased media spend, expansion of our sales force, and other brand support investments. We are planning continued increases in investments in advertising, promotional and selling expenses behind existing brands in an attempt to maintain the momentum, as well as in innovation, commensurate with the opportunities and the increased competition that we see. We do not expect that the depletions growth rates we experienced in the first quarter will be maintained for the remainder of the year, as we face tougher comparables and the first quarter benefit from new product launches is unlikely to be replicated during the balance of 2014. Accordingly, we have not increased our estimated full year 2014 depletion growth rate.”

Mr. Roper went on to say, “Our supply chain performance improved during the quarter, but still remains below our expectations. The high demand levels, unseasonal weather and planned shutdowns for maintenance and efficiency improvements caused us to experience higher operational and freight costs than we had originally expected. While our growth continues to challenge us operationally, we have improved our service level to our distributors and decreased our product shortages. Projects at the breweries to add capacity in preparation for peak volumes later this year are starting to be commissioned and we expect most to be fully operational during the second quarter. Compared to this time last year, we will have significantly increased our brewing, packaging and shipping capabilities and our tank capacity at our Pennsylvania Brewery and our Cincinnati Brewery. Given the opportunities that we see, we expect a continued high level of brand investment and capital investment as we pursue growth and innovation. We are prepared to forsake the earnings that may be lost as a result of these investments in the short term, as we pursue long term profitable growth.”

1st Quarter 2014 Summary of Results

Depletions grew 34% from the comparable 13-week period in the prior year, primarily due to depletion increases across our Angry Orchard^®, Samuel Adams^® and Twisted Tea^® brands.

Core shipment volume was approximately 835,000 barrels, a 32% increase compared to the first quarter of the prior year.

The Company believes wholesaler inventory levels at March 29, 2014 were at appropriate levels. Inventory at wholesalers participating in the Freshest Beer Program at March 29, 2014 was unchanged in terms of days of inventory on hand when compared to March 30, 2013. The Company has over 65% of its volume on the Freshest Beer Program and it believes participation in the Program could reach between 70% and 75% of its volume by the end of 2014.

Gross margin decreased to 49% compared to 50% in the first quarter of 2013. The margin decrease was a result of product mix effects, increases in brewery processing costs, and increases in customer program and incentive costs, which were only partially offset by price increases.

Advertising, promotional and selling expenses were $17.8 million higher than costs incurred in the first quarter of 2013. The increase was primarily a result of increased investments in media advertising, point of sale and local marketing, increased costs for additional sales personnel and commissions, and increased freight to distributors due to higher volumes.

General and administrative expenses increased $1.2 million compared to the first quarter of 2013, primarily due to increases in salary and benefit costs and consulting expenses.

The Company expects that its March 29, 2014 cash balance of $28.0 million, together with its future operating cash flows and the $150.0 million line of credit, will be sufficient to fund future cash requirements.

Depletion estimates

Year-to-date depletions through the 16 weeks ended April 19, 2014 are estimated by the Company to be up approximately 33% from the comparable period in 2013.

Fiscal 2014 Outlook

The Company has left unchanged its projected 2014 earnings per diluted share of between $6.00 and $6.40. The Company’s actual 2014 earnings per share could vary significantly from the current projection. Underlying the Company’s current projection are the following estimates and targets:

About the Company

The Boston Beer Company began in 1984 with a generations-old family recipe that Founder and Brewer Jim Koch uncovered in his father’s attic. Inspired and unafraid to challenge conventional thinking about beer, Jim brought the recipe to life in his kitchen. Pleased with the results of his work, Jim decided to sample his beer with bars in Boston in the hopes that drinkers would appreciate the complex, full-flavored beer he brewed fresh in America. That beer was aptly named Samuel Adams Boston Lager^®, in recognition of one of our nation’s great founding fathers, a man of independent mind and spirit. Little did Jim know at the time, Samuel Adams Boston Lager would soon become a catalyst of the American craft beer revolution.

Today, The Boston Beer Company brews more than 50 styles of beer. It relentlessly pursues the development of new styles and the perfection of classic beers by searching the world for the finest ingredients. Using the traditional four vessel brewing process, the Company often takes extra steps like dry-hopping, barrel-aging and a secondary fermentation known as krausening. The Company has also pioneered another revolution, the ‘extreme beer’ movement, where it seeks to challenge drinker’s perceptions of what beer can be. The Boston Beer Company has been committed to elevating the image of American craft beer by entering festivals and competitions around the globe, and is one of world’s most awarded breweries at international beer competitions. As an independent company, brewing quality beer remains its single focus. Although Samuel Adams^® beer is America’s largest-selling craft beer, it accounts for only one percent of the U.S. beer market. The Boston Beer Company will continue its independently-minded quest to brew great beer and to advocate for the growth of craft beer across America. In addition to Samuel Adams beers and the other craft brands brewed by Alchemy & Science, its craft brew incubator, the Company also brews Twisted Tea^® and Angry Orchard^® hard cider.
