HARRISBURG, Pa., Jan. 31, 2005 (PRIMEZONE) -- Worldwide industrial services and products company Harsco Corporation (NYSE:HSC) today reported record fourth quarter and full-year 2004 results from continuing operations.
Fourth quarter 2004 diluted EPS from continuing operations was a record $0.84, up 35 percent from $0.62 in the fourth quarter of 2003. Fourth quarter income from continuing operations was a record $35.0 million, compared with $25.7 million last year, an increase of 36 percent. Fourth quarter sales totaled $711 million, also a record, and up 26 percent from sales of $564 million in the same period last year. Positive foreign currency translation contributed $25 million to 2004's fourth quarter sales and $1.6 million to pre-tax income.
For the full year 2004, income from continuing operations was $113.5 million, or $2.73 diluted earnings per share, both records, compared with income from continuing operations of $87.0 million, or $2.12 per share in 2003, an increase in income and diluted EPS of 31 percent and 29 percent, respectively. Sales for the full year 2004 reached a record $2.5 billion, an increase of 18 percent from last year's sales of $2.1 billion. Positive foreign currency translation contributed approximately $109 million to sales in 2004 and $5.4 million to pre-tax income.
Income from discontinued operations in 2004 was $7.7 million after-tax, or $0.18 per diluted share, principally reflecting the previously reported favorable settlement of the Federal Excise Tax (FET) dispute, from which the Company received a cash payment refund of approximately $12.5 million in the fourth quarter of 2004. Income from discontinued operations in 2003 was $5.2 million, or $0.13 per diluted share, principally from the Company's reassessment of its litigation reserve in the FET matter, as previously reported. Including discontinued operations, full year 2004 net income was $121 million or $2.91 per diluted share, compared with net income of $92.2 million or $2.25 per diluted share in 2003.
Commenting on the Company's results, Harsco Chairman, President and Chief Executive Officer Derek C. Hathaway said, "Our strong fourth quarter performance completed a year in which record operating results in sales, income, EPS and cash flows were achieved, reflecting the successful execution of our strategies for growing our Mill Services business, and improved operating results from other business units, particularly the positive contribution of our international Access Services business and the significant turnaround of our industrial grating business. We enter 2005 having established a clear platform for Harsco's continued growth, armed with a strong balance sheet, growing cash flows and broad-based market opportunities.
"Much of this growth will come from our own internal investments, augmented by targeted acquisitions, and funded by our historically strong operating cash flows. Harsco's growth and investment will be accomplished under our formal Economic Value Added (EVA(r)) discipline, which we successfully implemented three years ago. The EVA culture is pervasive throughout Harsco, creating a direct link to shareholder value by incorporating return and profit measures into a single metric and ensuring accountability for stockholder capital. This is evidenced not only by our record 2004 operating results but also by our significant EVA increases in each of the past two years."
Fourth Quarter Business Review
Mill Services
Sales in the fourth quarter increased by more than 20 percent to $274 million from $227 million in last year's fourth quarter. Organic growth was responsible for $33 million of the increase, or approximately 14 percent, while positive foreign currency translation contributed $14 million, or approximately 6 percent. Operating income for the quarter rose 33 percent to $30.4 million, up from $22.8 million in the same period last year. Positive foreign currency translation increased operating income by approximately $1.5 million. Operating margins improved by 110 basis points to 11.1 percent from 10.0 percent in the fourth quarter last year. Performance benefited from a combination of higher steel production at mills serviced, new contract signings, and the Company's six-sigma efficiency improvements and other ongoing cost reduction initiatives.
Entering 2005, the Company reaffirms its positive outlook for the Mill Services segment. Contract backlogs remain strong and additional new contract signings should add to this strength. The Company will continue to focus on growing this business and intends to dedicate a significant portion of its cash flows towards this strategic objective. Through its six-sigma and EVA initiatives, the Company also expects further incremental margin improvement in 2005 and beyond.
Access Services
Fourth quarter sales increased 19 percent to $189 million from $159 million last year. Organic sales growth contributed $20 million, or approximately 13 percent, and positive foreign currency translation increased sales by nearly $10 million, or approximately 6 percent. Operating income increased 21 percent to $13.3 million, from $11.0 million in the fourth quarter of 2003. Positive foreign currency translation contributed approximately $0.5 million to operating income in the quarter. Operating margins increased by 10 basis points to 7.0 percent from 6.9 percent in last year's fourth quarter.
The quarter's improved operating performance in this segment continued to be led by growth from international operations, with overall performance ahead of last year's fourth quarter in the Middle East, the United Kingdom, Eastern Europe, and Canada.
The outlook for the Access Services segment in 2005 continues to improve, with increased non-residential spending and industrial maintenance activity expected in the Company's major markets, continued development of newer markets in Eastern Europe and Australia, and further market penetration from new products.
Engineered Products and Services ("All Other")
Sales in the fourth quarter increased 60 percent to $154 million from $96 million last year. Operating income increased to $14.0 million, up 19 percent from $11.8 million in the fourth quarter of last year. Positive foreign currency translation in the quarter increased sales by approximately $0.7 million, and operating income by $0.2 million. Operating margins decreased to 9.1 percent from 12.3 percent in the prior year's fourth quarter, as increased commodity costs, particularly steel, led to higher cost of sales compared with last year.
The quarter's improved results were led by higher sales, income and margins from Harsco Track Technologies. As expected, HTT delivered a significant number of units in the quarter, principally to international customers. Also reporting improved sales, income and margins in the quarter was the Company's Reed Minerals business. Margins for IKG declined due to higher commodity costs. While the two other businesses in this group, Patterson-Kelley and Air-X-Changers, reported higher sales in the quarter, income was down for each as higher costs resulted in lower margins.
The outlook for the Engineered Products and Services group in 2005 remains positive. Improved results should again be led by the Harsco Track Technologies unit as it further penetrates its domestic and international markets with additional equipment sales and contract services. The moderating commodity costs expected in 2005 compared with 2004 should positively affect margins for this group.
Gas Technologies
Sales in the fourth quarter were up 15 percent to $94 million from $82 million last year. Operating income of $3.6 million was down 23 percent from last year's $4.7 million. Operating margins declined from 5.7 percent in the fourth quarter of 2003 to 3.8 percent in this year's fourth quarter. The effect of foreign currency translation was not material. As expected, income and margins were negatively impacted in the quarter by higher commodity costs, particularly steel, compared with last year's fourth quarter.
Looking ahead to 2005, the outlook for the Gas Technologies segment is positive. Product backlogs continue to improve, commodity costs are expected to moderate, international operations continue to perform well, and future benefits are expected from new product introductions. Measurable improvements in sales, income and margins are expected in 2005, particularly after the first quarter. Results for the first quarter are expected to be down in comparison with the first quarter of 2004, when results were favorably affected by accelerated purchasing of propane tanks by customers, in advance of anticipated price increases resulting from higher steel costs.
Liquidity, Capital Resources and Other Matters
Net cash provided by operating activities for the full year 2004 was a record $270 million, compared with $263 million in 2003. Cash used by investing activities was $210 million, compared with $145 million in the prior year, primarily due to increased capital expenditures for organic growth.
On a cash flow basis, debt was reduced by approximately $22 million in 2004, but due to the strengthening of major currencies against the U.S. dollar, particularly the British pound sterling and the euro, the translated balance sheet reflects a $12 million increase in debt, to $626 million. The Company's debt-to-capital ratio declined by 350 basis points to 40.6 percent in 2004, a continued improvement from the 44.1 percent at the end of 2003 and 49.8 percent at the end of 2002.
The effective income tax rate from continuing operations for the fourth quarter and full year 2004 was 26.4 percent and 28.6 percent, respectively, compared with 30.9 percent and 30.7 percent in the corresponding periods last year. The decrease in the 2004 fourth quarter tax rate is due primarily to a one-time benefit of approximately $1.5 million, or $.04 per diluted share, resulting from The American Job Creation Act of 2004, signed by President Bush in October 2004. The Act includes foreign tax credit relief for certain dividends paid by joint venture entities. The Company estimates that its effective tax rate from continuing operations in 2005 will be approximately 31 percent.
The success of the Company-wide EVA financial and operational initiative was clearly evident during 2004 with the achievement of a substantial improvement in EVA, including improvements from six of the Company's nine operating units over the prior year. Further improvements in EVA are expected in 2005 and beyond.
Outlook
Underpinned by its global industrial services businesses, the Company expects continued growth into 2005 and beyond. The overall outlook for each of the Company's business units is encouraging. Supported by strong levels of cash flow, the Company expects to make further growth investments in new long-term, high renewal-rate services contracts for the Mill Services business and for growth in the Access Services and Track Technologies rail services businesses. The Company will also continue to give consideration to sensible bolt-on acquisitions to further enhance its industrial services growth and increase EVA.
Based on foreign currency exchange rates as of mid-January 2005, the Company is refining its 2005 guidance for diluted EPS from continuing operations to $3.05 - $3.15 from the previous guidance given in early December of $3.00 - $3.10 per diluted share. This reflects an increase of 12-15 percent over 2004's diluted EPS from continuing operations of $2.73. Any further significant weakening or strengthening of the U.S. dollar against the foreign currencies of the countries in which the Company does business could have a further effect on 2005 results.
With regard to the first quarter of 2005, the Company expects its earnings from continuing operations to be in the range of $0.45 - $0.49 per diluted share, an increase of approximately 10-20 percent compared with $0.41 per diluted share in the first quarter of last year. The first quarter is historically the slowest quarter of the year for the Company due to seasonal factors and the impact that severe weather can have on a number of its operations.
