ESSENDANT REPORTS SECOND QUARTER 2018 RESULTS

DEERFIELD, Ill., July 26, 2018 – Essendant Inc. (NASDAQ: ESND), a leading national distributor of workplace items, today announced financial results for the second quarter ended June 30, 2018 as follows:

Second Quarter 2018 Summary

“Our second quarter results give us confidence that our strategy is working,” said Ric Phillips, President and Chief Executive Officer of Essendant.  “Our efforts to drive sales growth in key channels began to offset the decline from national resellers.  Our cost reduction efforts are successfully ramping, and our restructuring program continues to deliver expected results.  We expect to deliver an annualized run rate of cost savings over $50 million by 2020, with more than half of those savings realized this year.  In connection with our previously announced merger with Genuine Parts Company’s S.P. Richards business, we filed an amended Form S-4 last week and continue to work toward closing the merger by the end of the year.”

Reconciliation of Non-GAAP Financial Measures

Adjusted Gross Profit, Adjusted Operating Expenses, Adjusted Operating Income,

Adjusted Net Income, Adjusted Diluted Earnings Per Share, Adjusted EBITDA, and Free Cash Flow

The Non-GAAP table below presents Adjusted Gross Profit, Adjusted Operating Expenses, Adjusted Operating Income, Adjusted Net Income, Adjusted Diluted Earnings per Share, Adjusted EBITDA and Free Cash Flow for the three and six months ended June 30, 2018 and 2017 (in thousands, except per share data). These non-GAAP measures exclude certain non-recurring items and exclude other items that do not reflect the Company’s ongoing operations and are included to provide investors with useful information about the financial performance of our business. The presented non-GAAP financial measures should not be considered in isolation or as substitutes for the comparable GAAP financial measures. The non-GAAP financial measures do not reflect all of the amounts associated with our results of operations as determined in accordance with GAAP, and these non-GAAP financial measures should only be used to evaluate our results of operations in conjunction with the corresponding GAAP financial measures.

In order to calculate the non-GAAP measures, management excludes the following items to the extent they occur in the reporting period, to facilitate the comparison of current and prior year results and ongoing operations, as management believes these items do not reflect the underlying cost structure of our business. These items can vary significantly in amount and frequency.

Restructuring actions were taken in the three and six months ended June 30, 2018 that included facility consolidations, workforce reductions and product assortment refinements.

In the six months ended June 30, 2017, the Company recorded goodwill impairment which resulted from declines in sales, earnings and market capitalization.

In the three and six months ended June 30, 2018, these were charges related to transformational expenses, including potential merger, acquisition and equity investment transactions, and a gain reflecting receipt of payment on notes receivable reserved in 2015. In the three and six months ended June 30, 2017, other actions included litigation and transformational expenses.

Adjusted Gross Profit, adjusted operating expenses and adjusted operating income. Adjusted gross profit, adjusted operating expenses and adjusted operating income provide management and our investors with an understanding of the results from the primary operations of our business by excluding the effects of items described above that do not reflect the ordinary expenses and earnings of our operations. Adjusted gross profit, adjusted operating expenses and adjusted operating income are used to evaluate our period-over-period operating performance as they are more comparable measures of our continuing business. These measures may be useful to an investor in evaluating the underlying operating performance of our business.

Adjusted net income and adjusted diluted earnings per share. Adjusted net income and adjusted diluted earnings per share provide a more comparable view of our Company’s underlying performance and trends than the comparable GAAP measures. Net (loss) income and diluted (loss) earnings per share are adjusted for the effect of items described above that do not reflect the ordinary earnings of our operations.

Adjusted earnings before interest, taxes, depreciation and amortization (EBITDA). Adjusted EBITDA is helpful in evaluating our operating performance and is used by management for various purposes, including as a measure of performance and as a basis for strategic planning and forecasting. Net (loss) income is adjusted for the effect of interest and other expenses, net, taxes, depreciation and amortization and stock-based compensation expense. Management believes that adjusted EBITDA is also commonly used by investors to evaluate operating performance between competitors because it helps reduce variability caused by differences in capital structures, income taxes, stock-based compensation accounting policies, and depreciation and amortization policies.

Free cash flow. Free cash flow is useful to management and our investors as it is a measure of the Company’s liquidity. It provides a more complete understanding of factors and trends affecting our cash flows than the comparable GAAP measure. Net cash provided by operating activities and net cash used in investing activities are aggregated and adjusted to exclude the impact of acquisitions and equity investments, net of cash acquired and divestitures.

Outlook. Adjusted diluted earnings per share and free cash flow are non-GAAP measures. A quantitative reconciliation of non-GAAP guidance to the corresponding GAAP information is not available because the non-GAAP guidance excludes certain GAAP information that is uncertain and difficult to predict. The adjusted diluted earnings per share guidance excludes impacts in the three and six months ended June 30, 2018 of $0.25 and $1.88 per share, respectively, related to restructuring charges, transformational expenses and a payment on notes receivable reserved in 2015. Actual amounts appear in the non-GAAP table included later in this section. For the remainder of the year, the factors that will be excluded are currently unknown due to the level of unpredictability and uncertainty associated with these items, but may include actions such as future restructuring charges, transformational expenses and cash flow impacts of equity investments.
