2011 Outlook Provided

WOODLAND PARK, N.J.--(BUSINESS WIRE)--January 27, 2011--Cytec Industries Inc. (NYSE: CYT) announced today net earnings for the fourth quarter 2010 of $48.0 million or $0.95 per diluted share on net sales of $700 million. Included in the quarter are several special items that total $6.1 million of net income after-tax or $0.12 per diluted share and are outlined further in this release. Excluding these special items, net earnings were $41.9 million or $0.83 per diluted share.

Net earnings for the fourth quarter of 2009 were $9.8 million or $0.20 per diluted share on net sales of $648 million. Included in the quarter were several special items that totaled $24.6 million of net expense after-tax or $0.50 per share and are outlined further in this release. Excluding these special items, net earnings were $34.4 million or $0.70 per diluted share.

Shane Fleming, Chairman, President and Chief Executive Officer commented, “Earnings per share, excluding special items, increased almost 20% versus the same period in 2009. Our segment results were varied with Engineered Materials having a strong quarter as selling volumes were significantly higher across the commercial aerospace sector. Coating Resins selling volumes were flat with the prior period but raw material costs were up sharply and despite implementing significant price increases we were unable to fully recover the higher costs.”

Cytec Coating Resins sales increased 6% to $348 million; operating earnings decreased to $3.9 million.

In Coating Resins, overall selling volumes were flat as we experienced seasonal destocking in our industrial coatings markets in the fourth quarter 2010, particularly in Europe, versus restocking in the fourth quarter 2009. Selling prices increased by 9% and the impact of exchange rates decreased sales by 3%.

Operating earnings of $3.9 million were down versus operating earnings of $17.6 million in the fourth quarter of 2009. This was principally due to raw material cost increases of approximately $40.6 million not fully covered by selling price increases as well as reduced manufacturing production levels.

Cytec Additive Technologies sales increased 7% to $65 million; operating earnings increased to $8.8 million.

In Additive Technologies selling volumes were up by 6% versus the fourth quarter 2009 due to higher demand for our differentiated technologies globally. Selling prices increased by 2% and the impact of exchange rates decreased sales by 1%.

Operating earnings of $8.8 million were up significantly compared to the $4.2 million in the fourth quarter of 2009 mainly as a result of higher selling volumes and improved plant capacity utilization.

Cytec In Process Separation sales increased by 1% to $81 million; operating earnings decreased to $13.3 million.

In Process Separation selling volumes were down by 1% versus the fourth quarter 2009 and selling prices increased by 2%.

Operating earnings of $13.3 million were lower versus operating earnings of $15.2 million in the prior year quarter, mainly as a result of a less favorable product mix.

Cytec Engineered Materials sales increased by 15% to $206 million; operating earnings increased to $28.2 million.

In Cytec Engineered Materials, selling volumes increased by 15% compared to the prior year period, primarily due to improved demand related to new programs in the large commercial transport sector. Selling prices increased by 1% and the impact of exchange rates reduced sales by 1%.

Operating earnings of $28.2 million were up versus $22.8 million in the fourth quarter of 2009, mainly as a result of higher selling volumes and increased production levels. These benefits were partially offset by higher manufacturing and selling and technical service costs added as a result of the increasing demand levels and investment in growth programs.

Discontinued Operations

In the fourth quarter 2010 we committed to a plan to divest the Building Block Chemicals business and are in active discussions with a potential buyer. As a result, financial results in the segment are reported as discontinued operations excluding continuing costs that will remain as part of Cytec. For the three and twelve months ended December 31, 2010 continuing costs previously allocated to Building Block Chemicals but now included as part of corporate and unallocated were $1.5 and $6.3 million, respectively.

Shane Fleming, Chairman, President and Chief Executive Officer commented, “With an outstanding performance in 2010, it is an appropriate time to divest the business. The divestiture would allow us to put more attention and resources on our core growth platforms of Engineered Materials, In Process Separations and Waterborne and Radcure Coating Resins, focusing on organic growth and possible bolt-on acquisitions. Removing the high cyclicality of sales of this capital intensive commodity business from our business portfolio will also reduce the impact of its volatility to our earnings.”

The following covers Building Block Chemicals sales and earnings on the basis prior to being classified as discontinued operations. Sales were $150.6 million up 45% in the fourth quarter 2010 versus $103.9 million in the same period 2009 with higher selling volumes of 11% and selling prices increased by 34%. Operating earnings increased to $9.2 million due to the higher selling volumes and selling prices which more than offset higher raw material costs of approximately $32 million.

Special Items

In the fourth quarter of 2010 a number of special items were recorded that resulted in net pre-tax charges of $5.8 million ($6.1 million net benefit on an after-tax basis or $0.12 per diluted share) as follows:

• Included in Corporate and Unallocated, principally in manufacturing cost of sales, are pre-tax net restructuring charges of $1.1 million ($0.7 million after-tax or $0.01 per diluted share).
• Included in Other Income/Expense is a pre-tax charge of $4.7 million ($2.9 million after-tax or $0.06 per diluted share) related to an increase in environmental liabilities at two inactive locations for a change in estimate for operating and maintenance costs.
• Included in income tax expense is a benefit of $9.7 million or $0.19 per diluted share related to the reversal of deferred tax valuation allowances in two international entities.

In the fourth quarter of 2009 a number of special items were recorded that resulted in a net pre-tax charge of $36.7 million ($24.6 million after-tax or $0.50 per diluted share) as follows:

• Included in Corporate and Unallocated, principally in manufacturing cost of sales, is a pre-tax charge of $1.5 million ($0.8 million after-tax or $0.02 per diluted share) associated with various restructuring initiatives across Specialty Chemicals, Engineered Materials, and Corporate operations.
• Included in Corporate and Unallocated in General and Administrative is a net pre-tax charge of $5.2 million ($3.5 million after-tax or $0.07 per diluted share) related to the aforementioned restructuring initiatives.
• Included in Corporate and Unallocated, in manufacturing cost of sales is a pre-tax non-cash charge of $19.7 million ($15.6 million after-tax or $0.32 per diluted share) mainly due to accelerated depreciation of plant assets at the recently shutdown facility in Spain.
• Included in Corporate and Unallocated, a pre-tax asset impairment charge of $4.3 million ($3.4 million after-tax or $0.07 per diluted share) related to the write down of the land at our closed facility in Spain to its estimated fair value.
• Included in other income/(expense) is a net pre-tax non-cash loss of $12.2 million ($9.1 million after-tax or $0.18 per diluted share) associated with a settlement of an existing pension plan in an international jurisdiction. Also included in other income/expense is a pre-tax gain of $6.2 million ($3.8 million after-tax or $0.08 per diluted share) related to a legal settlement.
• Included in income tax expense is a benefit of $4.0 million or $0.08 per diluted share related to a favorable tax adjustment for an audit settlement in an international jurisdiction.

Income Tax Expense

Income tax benefit for the fourth quarter of 2010 was $7.0 million, compared with a tax benefit of $0.7 million in the fourth quarter of 2009. Included in income tax expense for the fourth quarter of 2010 is the aforementioned special item tax benefit of $9.7 million. This is related to the reversal of deferred tax valuation allowances for two international entities as revisions to the current and estimated future earnings for these entities now make the realization of such deferred tax assets more likely than not. Also included in income tax expense are discrete tax benefits of $3.5 million or $0.07 per diluted share mostly related to the favorable resolution of several prior year international tax matters. In addition, the fourth quarter results reflect a tax benefit of approximately $2.0 million or $0.04 per diluted share related to the cumulative tax catch-up on the first nine months of 2010 resulting from the December 17^th passage of the U.S. Tax Relief, Unemployment Insurance Reauthorization and Job Creating Act of 2010. The overall underlying estimated annual tax rate for the fourth quarter of 2010 was approximately 30.5% versus the underlying estimated annual tax rate in the fourth quarter of 2009 of 29.3%.

Cash Flow

David Drillock, Vice President and Chief Financial Officer commented, “Cash flow provided by operating activities was $97 million for the fourth quarter 2010 and our full year cash flow from operations was $279 million. During the quarter excellent progress continued related to our working capital initiative.” The following working capital amounts exclude Building Block Chemicals. Trade accounts receivable decreased by $26 million and days outstanding of approximately 49 days were down 2 days versus the end of the third quarter of 2010. Inventory decreased by $46 million and days on hand of approximately 66 days was reduced by 9 days versus the third quarter of 2010. Accounts payable decreased by $32 million in the quarter and days payable outstanding of approximately 48 days decreased by 5 days versus the third quarter of 2010. Mr. Drillock added, “We believe the overall gains made from the working capital initiative are sustainable going forward. As a result of this and many other efforts to improve cash flow during 2010, our cash balance at year end was $383 million versus $262 million at year end 2009.

“Capital spending of continuing operations for the quarter was $38 million with approximately 30% of the spending attributable to Engineered Materials, and 70% to Specialty Chemical segments. Capital spending for the full year 2010 was $116 million and our expectation for capital spending for the full year 2011 is to be in a range of $170 million to $190 million with the bulk of the increase related to manufacturing capacity expansions in the Engineered Materials segment.”

Capital spending of the discontinued Building Block Chemicals segment was approximately $7 million for the quarter and $15 million for the full year.

Debt was reduced by $18 million in the quarter and the overall debt balance is now $648 million versus $686 million at year end 2009.

Stock Buyback/Dividend Increase

The Company’s Board of Directors has approved the resumption of our stock buyback program, which has $44 million remaining on its current authorization, and also approved an additional stock buyback authorization of $150 million.

In addition, the Board of Directors approved an increase in the dividend level to $0.1250 from its prior level of $0.0125 and is effective with the first payment in February 2011. The quarterly cash dividend of $0.1250 per share of common stock is payable on February 25, 2011 to shareholders of record as of February 10, 2011. This restores the dividend to its level prior in April 2009 when the dividend was reduced due to the uncertain economic conditions at that time.

Mr. Drillock commented, “We entered 2010 with an excellent cash position provided from our working capital initiative and continued our good cash flow generation in 2010. This led us to resume our stock buyback program including the additional authorization, and increase our dividend back to prior levels. This is a clear indication of the Board of Director’s confidence in our future as well as our commitment to increasing the value of Cytec to our shareholders and employees.”

2011 Outlook

Mr. Fleming commented, “Looking forward to 2011, we are forecasting overall demand improving for our specialty chemical and materials segments. For our Specialty Chemical segments, Asia and Latin America will be higher growth with modest growth expected in North America and Europe. Raw material volatility remains a concern, particularly in our Coating Resins segment. In Engineered Materials, demand continues to improve in the commercial aircraft sectors, although growth in new programs will be less than originally anticipated. With the pending sale of Building Block Chemicals expected to be completed in the first quarter, we will compare our adjusted diluted earnings per share guidance to the continuing operations diluted earnings per share amounts in 2010. Our guidance for 2011 full year adjusted diluted earnings per share is a range of $3.15 to $3.50 on sales of $2.9 to $3.0 billion which compares to sales of $2.7 billion and adjusted diluted earnings per share from continuing operations in 2010 of $2.99. Our guidance by segment follows.”

In Coating Resins, the recovery of demand in the global industrial coatings market continues at a slow rate, with most of the growth expected in the Asia Pacific region. Cytec will continue to penetrate the emerging markets with our more environmentally friendly technologies. We estimate that global selling volumes in 2011 will improve approximately 5% over 2010 levels across the product lines. The forecast assumes higher raw material costs which we expect to offset with higher selling prices. Taking all the above into account, sales are projected to be in a range of $1.50 to $1.52 billion versus sales of $1.42 billion in 2010 and operating earnings are expected to be in a range of $70 million to $80 million for this segment, up from the 2010 operating earnings of $69 million.

In Additive Technologies, market acceptance of our technologically differentiated products continues to increase, particularly in Asia. Overall, Additive Technologies selling volumes are expected to improve slightly over 2010, with volume increases partially offset by the exit of discontinued lower margin products. We are planning to expand our capacity later this year to handle the demand increases related to our polymer additives products which will allow further volume growth in 2012. Taking this into account, sales are projected to be in a range of $260 million to $280 million versus sales of $259 million in 2010 and operating earnings are projected to be in a range of $37 million to $40 million for this segment, a modest increase versus 2010 operating earnings of $37 million.

The long-term trend of infrastructure builds in emerging markets continues to favor the In Process Separation segment driving increased demand for both the mining and phosphine chemicals product lines. Market acceptance of Cytec’s new products continues, particularly in the copper, alumina and newly targeted industrial mineral markets. Expectations are for full year sales to be in a range of $320 million to $330 million compared to sales of $292 million in 2010 and for full year operating earnings to be in a range of $60 million to $70 million, up from the 2010 operating earnings of $55 million.

In Engineered Materials, the secular trend of higher levels of composite usage across the aerospace market remains intact and there continues to be a large number of growth opportunities, not only in the U.S., but internationally as well. For 2011, the expectation is for an approximate 8% increase in overall selling volumes driven primarily by increases in the large commercial and the business and regional jet sectors partially offset by decreases in the military sector as production on the F-22 program winds down and the Joint Strike Fighter is in the early stages of ramp up. Taking this into account, full year sales for 2011 are projected to be in a range of $825 million to $845 million compared to sales of $774 in 2010 and operating earnings are expected to be in a range of $130 to $140 million for this segment, up from 2010 operating earnings of $116 million.

The guidance for Corporate and Unallocated is an operating expense of approximately $16 to $18 million for the year, Other Expense is forecasted to be approximately $4 million, and interest expense, net, is expected to be between $37 and $39 million. The forecast for the underlying annual tax rate for ongoing operations is expected to be in a range of 30.5% to 32.5%.

In closing, Mr. Fleming commented, “I am extremely pleased and proud of the people of Cytec for the successful execution of our important improvement initiatives in 2010 and the realignment of our portfolio to focus on our growth businesses. While there are still uncertainties ahead in 2011, these efforts will enable us to better leverage future sales growth into stronger earnings and cash flow, real evidence of which was demonstrated in 2010. We are in a great position to deliver our growth strategy of bringing high-performance product and application technologies to market that create value for our customers and will deliver increasing value and returns for our shareholders.”
