Neenah Reports Record Results in 2015 Second Quarter

E.P.S. of $0.97 up 8% versus prior year

ALPHARETTA, GEORGIA — August 5, 2015 — Neenah Paper, Inc. (NYSE:NP) today reported 2015 second quarter results.

Second Quarter Highlights

·Record earnings per diluted share of $0.97 increased 8 percent compared with adjusted earnings per share of $0.90 in 2014. Adjusted E.P.S. in 2014 excluded $0.02 for acquisition and restructuring costs.

·Record operating income of $27.9 million, up 5 percent from prior year adjusted operating income of $26.6 million. Adjusted operating income in 2014 excluded $700,000 of acquisition and restructuring costs.

·Consolidated sales of $224 million, down 3 percent but up 4 percent on a constant currency basis. Organic and acquisition-driven growth in Technical Products offset by translation impact from a weaker euro and lower Fine Paper and Packaging shipments.

·Record free cash flow (cash from operations less capital spending) of $33 million.

·Dividend paid at increased quarterly rate of $0.30/share.

·Acquisition of FiberMark completed on August 1, 2015 and expected to accelerate growth in premium packaging and related Technical Products markets.

“Adjusted earnings” is a non-GAAP measure and is used to improve comparability of year-on-year results. Adjusted figures are reconciled to GAAP later in this release.

“Our businesses performed well in the quarter, delivering record earnings and cash flows. In Technical Products, impressive organic growth was boosted by last year’s filtration acquisition, and Fine Paper and Packaging continues to deliver very attractive financial returns.” said John O’Donnell, Chief Executive Officer. “It’s a testament to the strength of our teams that they can deliver these record results while at the same time completing a thorough diligence and successful execution of the FiberMark acquisition.  We are now focused on integration and excited by the capabilities FiberMark brings to accelerate growth in premium packaging and performance materials. Our balance sheet remains strong, providing future flexibility and the ability to optimize capital deployment among high-returning organic investments, value-adding acquisitions and increasing cash returns to shareholders.”

Quarterly Consolidated Results

Income Statement

Consolidated net sales of $224.1 million in the second quarter of 2015 were down 3 percent compared with $230.4 million in the second quarter of 2014. Volume growth in Technical Products and a higher value mix and selling prices in both segments were offset by currency translation, which reduced consolidated sales by 7 percent or $15 million due to a weaker euro, as well as lower Fine Paper & Packaging shipments.

Selling, general and administrative (SG&A) expense was $20.8 million in the second quarter of 2015 and compared with $20.4 million in the second quarter of 2014.

Operating income of $27.9 million in 2015 increased 5 percent compared with adjusted operating income of $26.6 million in the second quarter of 2014. Prior year adjusted operating income excluded $0.7 million for restructuring and acquisition costs mostly related to Technical Products. Income growth in 2015 resulted from a higher value mix, improved selling prices and lower input costs that more than offset increased SG&A and negative impacts of currency translation and higher manufacturing costs.

Net interest expense of $2.8 million in the second quarter of 2015 decreased slightly from $2.9 million in the second quarter of 2014.

The effective income tax rate of 33 percent in the second quarter of 2015 compared with 35 percent in the second quarter of 2014. The year to date rate of 35 percent in 2015 reflects a Federal manufacturing deduction now available following consumption of net operating losses.

Cash Flow and Balance Sheet

Cash provided from operations in the second quarter of 2015 was $39.4 million compared with $37.1 million in the second quarter of 2014. Increased cash generation in 2015 resulted primarily from increased earnings.

Capital spending of $6.9 million in the second quarter of 2015 compared with $4.8 million in the prior year period. Spending in 2015 will exceed prior year primarily due to an investment in transportation filtration capacity to support growth in the Americas by repurposing an existing fine paper machine.

Debt as of June 30, 2015 was $215.5 million compared to $223.2 million at March 31, 2015 and $234.3 million on December 31, 2014. Cash and equivalents as of June 30, 2015 were $78.0 million compared with $58.8 million as of March 31, 2015 and $72.6 million as of December 31, 2014. On August 1, 2015, the FiberMark acquisition was financed using $80 million of cash and $43 million of debt drawn against the Company’s existing revolving credit agreement.

Quarterly Segment Results

Technical Products net sales of $119.0 million increased 2 percent compared with prior year sales of $116.9 million. The growth in sales resulted from increased volumes (including the acquisition), a higher value product mix and increased selling prices, partly offset by unfavorable currency effects. Sales on a constant currency basis grew 15 percent (4 percent excluding the acquisition), led by gains in transportation and other filtration markets and in labels.

Operating income of $15.3 million in the second quarter of 2015 increased 12 percent compared with prior year adjusted income of $13.7 million. In 2014, adjusted operating income included approximately $0.5 million for restructuring costs. Higher operating income in 2015 resulted from volume growth (including the acquisition), improved net selling prices, and lower input costs. These items were only partly offset by currency impacts.

Fine Paper & Packaging net sales were $98.3 million in the second quarter of 2015, down 8 percent compared with a record $106.6 million in the prior year. Higher selling prices and an improved mix were offset by a 10 percent volume decrease. Volume declines reflected decreased large volume shipments of lower value non-branded products, as well as impacts from customer consolidation. These items were partly offset by good performance in premium packaging and retail sales.

Operating income of $17.3 million in the second quarter of 2015 was unchanged from the prior year. Benefits from higher net prices, a more profitable mix, and lower input costs were able to offset impacts due to reduced volumes.

Unallocated Corporate and Other includes unallocated corporate costs and results from certain non-premium paper grades. Unallocated corporate costs in the second quarter of 2015 were $4.8 million compared with $4.5 million in prior year period. In 2015, sales of non-premium paper grades were $6.8 million, with operating income of $0.1 million, compared with sales in 2014 of $6.9 million and an operating loss of $0.1 million.

Year to Date

Year-to-date net sales of $452.3 million in 2015 decreased 1 percent compared with $455.5 million in 2014. The decreased revenues resulted from a $29 million (6 percent) negative impact due to currency translation that offset volume-driven growth in Technical Products and improved pricing and mix in both segments.

Operating income of $56.7 million in 2015 increased 16 percent compared with $48.9 million in 2014 and resulted from growth in sales volume, a more favorable mix and higher selling prices, lower input costs and the absence of $1.0 million of restructuring and acquisition costs. Partly offsetting these items were unfavorable currency translation and higher SG&A and mill costs.

Net income from continuing operations was $33.0 million in 2015 compared with $28.2 million in 2014. Increased income in 2015 resulted primarily from higher operating income. Year to date earnings per diluted common share of $1.92 increased 16 percent from $1.66 in 2014. After excluding costs for restructuring in 2014, earnings per share increased 14 percent to $1.92 in 2015, compared with adjusted earnings per share of $1.69 in the prior year-to-date period.

Cash provided by operating activities of $44.5 million for the six months ended June 30, 2015 was $7.4 million lower than the prior year period.  Increases in cash from operations in 2015 due to higher operating income and lower pension contributions were offset by differences in working capital and higher cash tax payments in 2015. Working capital differences included increased amounts in 2015 due to higher sales and a favorable one-time item in 2014 for changes in terms for certain vendors.

Year-to-date capital spending of $12.6 million compared with $9.1 million in the prior year. Higher spending in 2015 is primarily a result of the U.S. filtration capacity project.
