(ATLANTA — October 9, 2013) — Zep Inc. (NYSE: ZEP), a leading consumable chemical packaged goods company that manufactures a wide variety of high-performance maintenance and cleaning chemicals, today reported financial results for the three-month and twelve-month periods ended August 31, 2013.

“This quarter was about delivering on near-term commitments while laying the foundation for future growth,” said John K. Morgan, Chairman, President and Chief Executive Officer of Zep Inc.  “We achieved our sales projections for the fourth quarter, generated significant free cash flow and de-levered the balance sheet following our most recent acquisition.  We achieved all of this while progressing with a restructuring program that we believe will significantly enhance both the abilities of our selling organizations and the efficiency of our supply chain operations,” continued Mr. Morgan.

Net Sales grew 6.1% in the fourth fiscal quarter of 2013 to $182.2 million, due to better than expected promotional activity at retailers and the inclusion of Zep Vehicle Care, which added $16.2 million to net sales.  Gross profit margin in the fourth fiscal quarter of 2013 increased 130 basis points to 46.8% compared to the prior year, primarily due to improved channel mix resulting from the inclusion of Zep Vehicle Care in the current year results.  EBITDA decreased $3.9 million to $11.8 million primarily due to the $5.2 million restructuring charge, partially offset by the inclusion of Zep Vehicle Care EBITDA in the current year.  Adjusted EBITDA, which excludes the fourth quarter restructuring charge, increased $1.3 million to $16.9 million, representing an Adjusted EBITDA margin of 9.3%.  In the fourth fiscal quarter, the company generated $28.5 million of free cash flow and was able to reduce net debt by $29.2 million to $207.5 million and to reduce its leverage ratio to 3.31x, which is consistent with managements’ fiscal year-end goals.

We continue to execute plans for a variety of complexity-reduction activities, including facilities consolidation, process simplification, product-line and customer rationalization and headcount reductions related to such activities.  During the fourth quarter of fiscal 2013, we recorded a $5.2 million restructuring charge in connection with these efforts and expect to record $1 million to $2 million in additional charges during the next few quarters.  We continue to believe these actions will result in annualized cost savings ranging from $8 million to $12 million, and that we remain on target to realize approximately $9 million of these savings during fiscal 2014.

Net Sales in fiscal 2013 increased 5.5% to $689.6 million, finishing at the high end of our previously announced range of $685-$690 million.  Net sales growth was driven primarily by $55.2 million of acquisition-related revenue and $5.4 million of price, partially offset by $19.4 million of organic volume declines and $5.2 million as a result of two fewer selling days in fiscal 2013.  Gross profit margin for fiscal 2013 increased 110 basis points to 47.1% primarily due to favorable channel mix resulting from the inclusion of Zep Vehicle Care in the current year.  Adjusted EBITDA increased $3.5 million to $57.1 million for an Adjusted EBITDA margin of 8.3%.  Free cash flow increased $33.7 million to $38.0 million, producing $1.69 of free cash flow per diluted share.

“Fiscal 2013 was filled with both opportunities and challenges.  I’m proud of the way our associates have risen to the occasion and created numerous prospects for growth.  Over the next several quarters, execution against our near-term strategies will be absolutely critical,” said Mr. Morgan.  “In 2014, we will improve profitability by focusing on cost-control, complexity reduction and completing the integration of Zep Vehicle Care while continuing to invest in product innovation and our sales pipeline.  In doing so, I’m confident we will continue to reduce debt and position the business for profitable growth,” Mr. Morgan concluded.

A variety of other risks and uncertainties could cause our actual results to differ materially from the anticipated results or other expectations expressed in our forward-looking statements.

The unaudited consolidated financial statements presented in accordance with accounting principles generally accepted in the United States (“GAAP”) are supplemented by a table of adjusted operating results, which includes non-GAAP financial information that is referenced in this press release, which includes EBITDA, adjusted EBITDA and free cash flow and free cash flow per share.  This non-GAAP financial information is provided to enhance the user’s overall understanding of our financial performance.
