(ATLANTA — July 10, 2014) — 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 and nine-month periods ended May 31, 2014.

“I am proud of what the team has accomplished in terms of bringing in new business.  Revenue growth was 0.6% in total, 2.1% on a same number of selling days basis and 4.7% when excluding 2.6% of revenue eliminated as a result of complexity reduction activities implemented late in fiscal 2013,” said John K. Morgan, Chairman, President and Chief Executive Officer of Zep Inc.

Morgan continued, “We are making excellent progress on our business continuity plan execution as we recover from the incident at our aerosol production facility, but realize this will create some uncertainty with respect to our future operational and financial results.  We are communicating with our customers and working to minimize disruptions in the supply of aerosol products.  We continue to believe our insurance will cover the majority of the costs associated with this incident, including business interruption; however we expect the timing of expenditures and insurance recovery to be misaligned.”

Net sales in the quarter were $187.0 million.  The 0.6% increase was the net result of growth in most of our targeted strategic end-markets offset by the expected impact of our complexity reduction initiative, decreases in other institutional and industrial end-markets and one less selling day.

Gross profit margin in the second quarter of fiscal 2014 was 46.5% or 20 basis points lower than the comparable quarter of fiscal 2013 due to increased raw material input costs and channel mix, partially offset by pricing actions.  Selling, distribution and administrative expenses were $0.4 million lower than last year on a reported basis and would have been $2.2 million, or 2.9% lower, if not for the addition of $0.5 million of incremental California legal costs in the current period and a favorable $1.4 million legal recovery in the third fiscal quarter of last year.  Additionally, unexpected increases in freight impacted selling, distribution and administrative expense in the current quarter.

“While we are encouraged by recent sales results, we believe that continuing sales pipeline success may only partially offset the fire-related sales losses potentially resulting in revenue declines in some or all of the next four quarters,” continued Morgan.  “We invested in a number of initiatives over the past year that started to deliver results in the most recent quarter.  Had it not been for the incident, we expected these initiatives to continue to gain traction in the fourth quarter and beyond.  However, we are now focused on implementing our business continuity plan with an eye on mitigating the impact of disruption, and believe that the returns on recent investments may be delayed as we manage through the recovery period.”

During the third quarter of fiscal 2014, management recorded a non-cash impairment of $5.7 million for the loan to Zep Inc.’s innovation partner as a result of their failure to make a scheduled principal payment and future uncertainty over recoverability of the loan.

In addition, we or our executive officers on our behalf, may from time to time make forward-looking statements in reports and other documents that are filed with the SEC or in connection with oral statements made to the press, potential investors or others.

Our forward-looking statements are subject to certain risks and uncertainties that could cause actual results, expectations, or outcomes to differ materially from our historical experience as well as management’s present expectations or projections. These risks and uncertainties include, but are not limited to:

·                  impact of the fire on financial results;

·                  economic conditions in general;

·                  the cost or availability of raw materials;

·                  pricing;

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. A number of those risks are discussed in Part I, “Item 1A. Risk Factors” of our Annual Report on Form 10-K for the fiscal year ended August 31, 2013 and in Part II “Item 1A, Risk Factors” of our Quarterly Report on Form 10-Q for the quarter ended May 31, 2014.

Further, forward-looking statements speak only as of the date they are made, and management undertakes no obligation to update publicly any of them in light of new information or future events.

The unaudited consolidated financial statements presented in accordance with accounting principles generally accepted in the United States (“GAAP”) are supplemented by a table that reconciles EBITDA, adjusted EBITDA, adjusted earnings per diluted share and adjusted cash earnings per diluted share, which are non-GAAP financial information that are referenced in this press release, to the nearest GAAP measure.  This non-GAAP financial information is provided to enhance the user’s overall understanding of our financial performance. Specifically, management believes that EBITDA, adjusted EBITDA, adjusted earnings per diluted share and adjusted cash earnings per diluted share may provide additional information with respect to our performance or ability to meet our future debt service obligations, capital expenditures and working capital requirements.  This non-GAAP financial information should be considered in addition to, and not as a substitute for, or superior to, results prepared in accordance with GAAP.  Moreover, this non-GAAP information may not be comparable to EBITDA, adjusted EBITDA, adjusted earnings per diluted share or adjusted cash earnings per diluted share reported by other companies because the items that affect net earnings that we exclude when calculating EBITDA, adjusted EBITDA, adjusted earnings per diluted share and adjusted cash earnings per diluted share may differ from the items taken into consideration by other companies.
