Executive Commentary:

Allen L. Shiver, president and chief executive officer, said, “Our team delivered an outstanding second quarter, with both of our operating segments posting top- and bottom-line growth. In our core markets, new products combined with our enhanced brand strategy brought consumers to our brands and improved margins. In our expansion markets, we continue to gain share with Wonder, Nature’s Own, and our other proven brands. Retail sales of our two largest cake brands, Tastykake and Mrs. Freshley’s, both posted growth, driven by the appeal of new products and expanded distribution.

“During the quarter, we also saw the benefit of our operational initiatives. Across a majority of our bakeries we realized improved manufacturing efficiencies, which, when combined with reduced input prices, drove margin expansion this quarter. This quarter, profitability at Lepage returned to more normalized levels, which also contributed to the strong margins in our DSD segment.

“Bringing a new bakery online can be challenging, but because of our experienced team’s hard work, the start up at our Lenexa, Kansas DSD segment bakery went very smoothly. Kansas City and other Midwestern expansion markets are key to our growth strategy, and with capacity closer to these markets we can better serve our independent distributors and consumers.

Shiver continued, “The record results we report today are the result of hard work from the entire Flowers team to deliver value to shareholders. Looking ahead, we have significant momentum as we continue to execute our strategy. To grow sales and attract consumers, we intend to innovate our product portfolio and leverage our strong brands. To increase margins, we will improve efficiencies and reduce our costs. And finally, we continue to seek out strategic acquisition opportunities in order to expand our brand portfolio and geographic footprint.”

DSD Segment Commentary

Of the total DSD segment sales increase, pricing/mix increased 0.7% and volume increased 1.4%. Branded retail sales were strong, primarily due to volume increases in white and soft variety breads. The increase in branded retail sales was partially offset by decreases in store branded retail due to exiting certain store branded business in the second half of fiscal 2014. The non-retail and other category posted solid volume growth, driven primarily by foodservice.

EBITDA and adjusted EBITDA margin for the DSD segment increased as a percentage of sales due to lower ingredient costs, improved manufacturing efficiencies, and cost-saving initiatives; partially offset by higher distribution costs.

Warehouse Segment Commentary

Of the Warehouse segment’s sales increase, pricing/mix increased 1.4%, while volume decreased 1.1%. Improved price/mix drove the increase in branded retail sales, and the improvement in store brand retail sales was primarily the result of higher store brand cake sales. The decision to exit the lower-margin, non-retail tortilla business in the second half of 2014 drove the decrease in the non-retail and other category.

Indicating the improved mix of business, EBITDA margin for the Warehouse segment increased as a percentage of sales primarily due to the exit from the non-retail tortilla business in the second half of fiscal 2014 and lower ingredient costs, partially offset by higher workforce-related and packaging costs.

Consolidated Results Commentary

As compared to the prior year second quarter, consolidated EBITDA and adjusted EBITDA increased. Unallocated corporate expenses were elevated during the quarter primarily due to higher consulting and legal expenses, and lower pension income; partially offset by lower stock-based compensation expense.

Interest expense declined due to lower outstanding debt balances, while a higher notes receivable balance drove an increase in interest income. Income tax expense as a percentage of pre-tax income increased slightly.

During the quarter, the company adjusted its estimate of the fair value of certain properties held for sale and identified a production line to be closed in the third quarter. As a result of these actions, the company recognized asset impairment charges during the quarter totaling $2.3 million.

Cash Flow

During the quarter, cash flow from operating activities was $97.5 million, capital expenditures were $20.6 million, and dividends paid were $30.5 million. During the quarter, the company paid down debt by $11.3 million.

Dividend

The board of directors will review the dividend at its next regularly scheduled meeting. Any action taken will be announced following that meeting.

Information Regarding Non-GAAP Financial Measures

The company prepares its consolidated financial statements in accordance with U.S. Generally Accepted Accounting Principles (GAAP). However, from time to time, the company may present in its public statements, press releases and SEC filings, non-GAAP financial measures such as, EBITDA, adjusted EBITDA, adjusted EBITDA margin, adjusted net income, adjusted net income per diluted share, adjusted EBIT, adjusted EBIT margin and gross margin excluding depreciation and amortization to measure the performance of the company and its operating divisions.

EBITDA is used as the primary performance measure in the company’s 2014 Omnibus Equity and Incentive Compensation Plan. The company defines EBITDA as earnings from continuing operations before interest, income taxes, depreciation, amortization and income attributable to non-controlling interest. The company believes that EBITDA is a useful tool for managing the operations of its business and is an indicator of the company’s ability to incur and service indebtedness and generate free cash flow. Furthermore, pursuant to the terms of our credit facility, EBITDA is used to determine the company’s compliance with certain financial covenants. The company also believes that EBITDA measures are commonly reported and widely used by investors and other interested parties as measures of a company’s

operating performance and debt servicing ability because EBITDA measures assist in comparing performance on a consistent basis without regard to depreciation or amortization, which can vary significantly depending upon accounting methods and non-operating factors (such as historical cost). EBITDA is also a widely-accepted financial indicator of a company’s ability to incur and service indebtedness.

Adjusted EBITDA, adjusted EBITDA margin, adjusted net income, adjusted net income per diluted common share exclude additional costs that we consider important to present to investors. These include, but are not limited to, the costs of closing a plant or costs associated with acquisition-related activities. We believe that financial information excluding certain transactions not considered to be part of the ongoing business improves the comparability of earnings results. We believe investors will be able to better understand our earnings results if these transactions are excluded from the results. These non-GAAP financial measures are measures of performance not defined by accounting principles generally accepted in the United States and should be considered in addition to, not in lieu of, GAAP reported measures. None of these non-GAAP measures should be considered an alternative to (a) income from operations or net income (loss) as a measure of operating performance; (b) cash flows provided by operating, investing and financing activities (as determined in accordance with GAAP) as a measure of the company’s ability to meet its cash needs; or (c) any other indicator of performance or liquidity that has been determined in accordance with GAAP. Our method of calculating EBITDA, adjusted EBITDA, adjusted EBITDA margin, adjusted net income, adjusted net income per diluted common share, and may differ from the methods used by other companies, and, accordingly, may not be comparable to similarly titled measures used by other companies.

Gross margin excluding depreciation and amortization is used as a performance measure to provide additional transparent information regarding our results of operations on a consolidated and segment basis. Changes in depreciation and amortization are separately discussed and include depreciation and amortization for materials, supplies, labor and other production costs and operating activities. Presentation of gross margin includes depreciation and amortization in the materials, supplies, labor and other production costs according to GAAP. Our method of presenting gross margin excludes the depreciation and amortization components, as discussed above. This presentation may differ from the methods used by other companies and may not be comparable to similarly titled measures used by other companies.

The reconciliations attached provide a reconciliation of our net income, the most comparable GAAP financial measure to EBITDA, adjusted EBITDA and adjusted net income, a reconciliation of adjusted EBITDA to cash flow from operations, a reconciliation of our gross margin excluding depreciation and amortization to GAAP gross margin, a reconciliation of net income per diluted common share to adjusted net income per diluted common share and reconciliations of operating income (EBIT) to EBITDA by segment.
