Deltic Announces Fourth Quarter and Year of 2006 Results

EL DORADO, AR — President and Chief Executive Officer, Ray C. Dillon, of Deltic Timber Corporation (NYSE-DEL) announced today that financial results for the fourth quarter of 2006 were a loss of $2 million, $.16 a share. These results compare to net income of $2.3 million, $.19 a share, in the corresponding 2005 quarter. The decrease in fourth quarter results was due primarily to a reduction in average realization for lumber combined with reduced residential and commercial real estate sales activity. For the year of 2006, net income totaled $11.3 million, $.91 a share, compared to $14.5 million, $1.18 a share, for the twelve months ended December 31, 2005.

Commenting on the results, Mr. Dillon stated, “The Company’s fourth quarter financial results were negatively affected by the continued slowdown in the housing market in the U.S. due primarily to increased interest rates and the resulting decrease in lumber consumption and prices. The Company’s financial results for the year of 2006 were respectable considering the difficult economic conditions that existed for our businesses throughout the year. Also, there were several significant highlights during 2006 that bear noting. Among these were: (1) our ability to maintain stable prices for our pine sawtimber despite the weakening lumber market, accomplished by adjusting the planned timing of the annual harvest volume, (2) the sale of almost 55 acres of premium commercial real estate property at a pretax margin of $11.2 million, (3) a record level of activity and residential lot sales in our Red Oak Ridge real estate development in Hot Springs, Arkansas, (4) a record year of financial performance at Del-Tin Fiber, our 50-percent joint venture to manufacture medium density fiberboard, and (5) improved efficiencies in the manufacturing process at our sawmills that enabled our Mills segment to produce positive cash flow for the year, despite the dismal lumber market.”

The Woodlands segment earned $2.9 million in the fourth quarter of 2006 compared to $3 million for the same period of 2005. The Company’s pine sawtimber harvest increased from 86,688 tons in the prior-year quarter to 90,958 tons in 2006’s fourth quarter. Average pine sawtimber price was $41 per ton for both reporting periods. Seasonal silviculture expenses amounted to $.8 million in the fourth quarter of 2006 versus $.1 million in the prior-year fourth quarter due to timing of these projects.

Deltic’s Mills segment reported a loss of $3.2 million in the fourth quarter of 2006 compared to a loss of $.2 million in the corresponding quarter of 2005. Finished lumber average sales price decreased $60 per thousand board feet to $287, and lumber sales volume decreased 32 percent when compared to 2005’s fourth quarter of 49.6 million board feet, primarily due to a reduction in operating hours in reaction to market conditions.

The Company’s Real Estate segment earned $1 million in the fourth quarter of 2006, which compares to $5.8 million for the same period of 2005. Results for 2006 included a sale of 2.1 acres of commercial property for $298,700 per acre, while 4.72 commercial acres were sold for an average of $1,011,500 per acre during the prior-year fourth quarter. Residential lot sales for the fourth quarter of 2006 decreased by 57 to 34, while the average lot price increased, due to sales mix, by $15,600 to $85,800 per lot, when compared to the fourth quarter of 2005.

Corporate operating expense was $3.4 million for 2006’s fourth quarter, which compares to $3.7 million for the corresponding period of 2005. Deltic’s equity in Del-Tin Fiber was income of $.2 million for the fourth quarter of 2006 compared to a loss of $.1 million for the same period in 2005. Interest expense for the fourth quarter of 2006 decreased $.5 million from 2005’s fourth quarter, to $1 million, as the Company has begun to capitalize interest related to its real estate development operations upon the adoption of the Securities and Exchange Commission’s recently issued Staff Accounting Bulletin No. 108. Since this adoption is required to be effective as of January 1, 2006, Deltic’s financial results for the first nine months of 2006 have been appropriately adjusted from the amounts previously reported.

Capital expenditures were $4.3 million for 2006’s fourth quarter and $27.8 million for the year of 2006. For the corresponding periods of 2005, capital expenditures totaled $8 million and $33.2 million, respectively.

For the year of 2006, the pine sawtimber harvest level was 580,316 tons compared to 581,242 tons for 2005. Average pine sawtimber price of $45 per ton was unchanged from the prior-year period. Finished lumber average sales price decreased $45, or 12 percent, from $369 per thousand board feet to $324. Lumber sales decreased 13.3 million board feet to 262.7 million. Residential lot sales for the current year totaled 116 lots at an average price of $103,800 per lot versus 2005’s sales of 249 lots at $78,600 per lot.

During 2006, 54.91 acres of commercial property were sold for $248,400 per acre, while 5.71 acres were sold for $945,800 per acre in 2005. Deltic’s equity in Del-Tin Fiber was income of $2.9 million for 2006, compared to essentially breakeven results in 2005. In 2005, the Company realized a non-cash income tax benefit of $1.7 million, created by a reversal of the valuation allowance related to accumulated state net operating loss carryforwards.

Regarding the outlook for the first quarter and year of 2007, Mr. Dillon noted, “We currently anticipate the pine sawtimber harvest to be 150,000 to 175,000 tons and 570,000 to 585,000 tons, respectively. Finished lumber production and sales volumes are estimated at 65 to 75 million board feet for the first quarter and 270 to 285 million for the year, but these volumes are dependent upon market conditions. Residential lot sales are projected at 10 to 20 lots and 100 to 120 lots for the first quarter and year of 2007, respectively.”
