Xerium Reports Q1 2017 Results

Highlights

Youngsville, NC - (BUSINESS WIRE) - May 1, 2017 - Xerium Technologies, Inc. (NYSE:XRM), a leading, global provider of industrial consumable products and services, today reported first quarter 2017 financial results.

Clifford Pietrafitta, Chief Financial Officer said, “We are pleased to see the effects of our repositioning efforts taking hold through improved volume and lower costs. During the first quarter of 2017, sales diversification and momentum from new products led to strong performance with 4.3% growth over the prior year. Higher sales combined with operational excellence program results led to an 11.0% improvement in adjusted EBITDA, while our order patterns remained strong and outpaced sales during the period.”

Pietrafitta continued, “Production levels improved during Q1 as our debottlenecking actions took effect. We are also pleased to report that during the quarter we shipped our first forming fabric from our new Machine Clothing manufacturing complex in Kunshan, China.

Q1 Financial Highlights:

Q1 net sales were $119.9 million, an increase of 5.5% year-over-year on a constant currency basis (see Table 1). The increase was driven by a constant currency sales increase of 9.8% in roll covers and 2.8% in machine clothing. Order patterns during the quarter remained strong with $128.0 million of orders and a quarter-end backlog of $181 million.

Q1 2017 gross profit was $47.5 million, or 39.6% of net sales, compared to $43.5 million, or 37.9% of net sales, in Q1 2016. Machine clothing gross margin improved to 42.9% in Q1 2017 from 40.1% in Q1 2016. The increase in gross profit margin was primarily due to production efficiencies, partially offset by negative currency effects. Rolls and service gross margin improved slightly to 34.6% in Q1 2017 from a gross margin of 34.2% in Q1 2016.

SG&A expenses (including Selling, G&A and R&D expenses) were $30.1 million, or 25.1% of net sales, in Q1 2017 versus $29.2 million, or 25.4% of net sales, in Q1 2016. The increase in SG&A expenses was due to incremental overhead costs related to the Spencer Johnston acquisition.

Q1 2017 basic loss per share was $(0.18) versus Q1 2016 of $(0.09). Basic adjusted earnings per share (see Table 3) were $0.06 in Q1 2017 compared to $0.07 in Q1 2016 as a result of higher interest, partially offset by improved operations.

GAAP income from operations in the first quarter of 2017 was $14.3 million, or 11.9% of sales, up $2.7 million, or 23.6% compared to Q1 2016. Q1 2017 adjusted EBITDA improved to $26.6 million, or 22.2% of net sales, compared to $23.9 million, or 20.8% of net sales in 2016, an increase of 15.8% on a constant currency, operational basis (see Table 2). The increase was driven by higher sales and operational efficiencies. In addition to interest, taxes, depreciation and amortization, adjusted EBITDA excludes expenses related to the Company’s restructuring activities, plant start-up costs, stock-based compensation, foreign currency gains and losses and non-recurring expenses. For a full reconciliation, refer to Table 4.

Cash taxes were $2.0 million in Q1 2017. Cash taxes are primarily impacted by income the Company earns in tax paying jurisdictions relative to income it earns in non tax-paying jurisdictions, primarily the United States.

Net cash used in operating activities was $(7.2) million and free cash flow was $(12.3) million (see Table 5) during the first quarter of 2017 as a result of a $23.6 million semi-annual bond interest payment, combined with a temporary build of inventory primarily related to the launch of the Kunshan, China forming fabric production start-up and production debottlenecking and expansion activities.

Net debt was $524.9 million at the end of Q1 2017 compared to $511.7 million at the end of Q4 2016. The Company’s net debt leverage ratio is 5.4x (see Table 6). The Company plans to utilize its free cash flow to pay down debt and de-lever over the remainder of its debt maturities.

2017 Outlook

As disclosed previously, the Company has repositioned its business to focus on growing end markets and geographies. These efforts have included the introduction of approximately 90 new products, the opening or acquisition of 4 facilities, the closure of 8 facilities, and the conversion of much of the Company’s equipment from graphical product set-ups over to non-graphical, growing product set-ups.

As previously reported, third party outlooks of the Company’s underlying markets indicate that a large number of new machines will be installed, especially in China, and that new machine startups are now outpacing machine closures by a 2 to 1 margin. Our Q1 results support this assessment.

With an improving market environment and the expected impact of repositioning programs, the Company expects 2017 full-year adjusted EBITDA to approximate 2016 levels, or be modestly higher. In addition, the Company expects 2017 free cash flow to be modestly lower than the prior year, as higher cash interest and negative currency impacts will not be fully offset by improved operational cash flow. Given this outlook, the Company is well positioned to execute against its 4 year, $100 million debt pay down program and naturally grow its business.

NON-GAAP FINANCIAL MEASURES

This press release includes measures of performance that differ from the Company’s financial results as reported under generally accepted accounting principles (“GAAP”). Management of the Company uses supplementary non-GAAP measures, including Adjusted EBITDA, Free Cash Flow, Net Debt and Adjusted EPS, internally to assist in evaluating its liquidity and financial and operational performance. Therefore, the Company believes these non-GAAP measures may also be useful to investors and financial analysts. Adjusted EBITDA and Free Cash Flow are specifically used in evaluating the ability to service indebtedness and to fund ongoing capital expenditures. Net Debt presents a view of the overall change in leverage from quarter to quarter. Adjusted EPS excludes certain items the Company does not believe to be indicative of on-going business trends in order to better analyze historical and future business trends on a consistent basis. Adjusted EBITDA, Free Cash Flow, Net Debt and Adjusted EPS should not be considered in isolation or as a substitute for net income (loss), net cash (used in) provided by operating activities, total debt or net income (loss) per share.

For additional information regarding non-GAAP financial measures and a reconciliation of such measures to the most comparable financial measures under GAAP, please see the applicable tables within this press release. In addition, the information in this press release should be read in conjunction with the corresponding exhibits, financial statements and footnotes contained in our Annual Report on Form 10-K for the year ended December 31, 2016 filed with the Securities and Exchange Commission on March 1, 2017 and our presentation that will accompany our conference call.

NET SALES

Table 1 summarizes Q1 net sales and the effect of currency translation rates. Change Excluding Currency is calculated taking the difference between Q1 2017 net sales at Q1 2016 FX rates (in US dollars) less Q1 2016 reported net sales

ADJUSTED EBITDA

Table 2 summarizes Q1 adjusted EBITDA and the effect of currency translation rates. Change Excluding Currency is calculated taking the difference between Q1 2017 adjusted EBITDA at Q1 2016 FX rates (in US dollars) less Q1 2016 reported adjusted EBITDA.

BASIC ADJUSTED EARNINGS PER SHARE

Table 3 represents a reconciliation of basic net loss per share to basic adjusted earnings per share for the three months ended March 31, 2017 and 2016:

EBITDA AND ADJUSTED EBITDA

EBITDA is defined as net income (loss) before interest expense, income tax provision (benefit) and depreciation (including non-cash impairment charges) and amortization.

“Adjusted EBITDA” means, with respect to any period, the total of (A) the consolidated net income for such period, plus (B) without duplication, to the extent that any of the following were deducted in computing such consolidated net income (loss) for such period: (i) provision for taxes based on income or profits, including, without limitation, federal, state, provincial, franchise and similar taxes, including any penalties and interest relating to any tax examinations, (ii) consolidated interest expense, (iii) consolidated depreciation and amortization expense, (iv)

reserves for inventory in connection with plant closures, (v) consolidated operational restructuring costs, (vi) noncash charges resulting from the application of purchase accounting, including push-down accounting, (vii) non-cash expenses resulting from the granting of common stock, stock options, restricted stock or restricted stock unit awards under equity compensation programs solely with respect to common stock, and cash expenses for compensation mandatorily applied to purchase common stock, (viii) non-cash items relating to a change in or adoption of accounting policies, (ix) non-cash expenses relating to pension or benefit arrangements, (x) expenses incurred as a result of the repurchase, redemption or retention of common stock earned under equity compensation programs solely in order to make withholding tax payments, (xi) amortization or write-offs of deferred financing costs, (xii) any non-cash losses resulting from mark to market hedging obligations (to the extent the cash impact resulting from such loss has not been realized in such period), (xiii) foreign currency losses and (xiv) other non-cash losses or charges (excluding, however, any non-cash loss or charge which represents an accrual of, or a reserve for, a cash disbursement in a future period), minus (C) without duplication, to the extent any of the following were included in computing consolidated net income (loss) for such period, (i) foreign currency gains and (ii) non-cash gains with respect to the items described in clauses (vi), (vii), (ix), (xi), (xii) and xiv (other than, in the case of clause (xiv), any such gain to the extent that it represents a reversal of an accrual of, or reserve for, a cash disbursement in a future period) of clause (B) above and (iii) provisions for tax benefits based on income or profits. Notwithstanding the foregoing, Adjusted EBITDA, as defined and calculated below, may not be comparable to similarly titled measurements used by other companies.

Consolidated net income (loss) is defined as net income (loss) determined on a consolidated basis in accordance with GAAP; provided, however, that the following, without duplication, shall be excluded in determining consolidated net income (loss): (i) any net after-tax extraordinary or non-recurring gains, losses or expenses (less all fees and expenses relating thereto), (ii) the cumulative effect of changes in accounting principles, (iii) any fees and expenses incurred during such period in connection with the issuance or repayment of indebtedness, any refinancing transaction or amendment or modification of any debt instrument, in each case and (iv) any cancellation of indebtedness income. Table 4 provides a reconciliation from net income (loss), which is the most directly comparable GAAP financial measure, to EBITDA and Adjusted EBITDA.

Adjusted EBITDA Definition Modification

During the 4^th quarter of 2016, the Company modified its definition of Adjusted EBITDA to exclude foreign exchange gains and losses from this non-GAAP measure. This change enhances investor insight into the Company’s operational performance. In previous filings, Q1 2016 Adjusted EBITDA was stated at $24.0 million based on the definition previously used.

FREE CASH FLOW

Table 5 summarizes free cash flow which is defined as net cash (used in) provided by operating activities less capital expenditures plus proceeds from disposals of property and equipment.

NET DEBT

Table 6 summarizes net debt which is defined as GAAP total debt less cash and deferred financing fees and net debt leverage which is defined as net debt divided by trailing twelve month Adjusted EBITDA.
