Deltic Announces Preliminary Third Quarter 2016 Results

EL DORADO, AR – Deltic Timber Corporation (NYSE-DEL) announced today that net income for the third quarter of 2016 was $1.5 million, $.12 a share, compared to net income of $.1 million for the third quarter of 2015. The improved results were primarily due to increased operating income from Deltic’s Manufacturing segment, resulting from an increased average sales price for lumber, combined with a lower per-unit manufacturing cost for the medium density fiberboard (“MDF”) sold during the third quarter of 2016; partially offset by increased Corporate general and administrative expense for incentive plan cost and professional fees. For the first nine months of 2016, net income was $6.1 million, $.50 a share, compared to net income of $2.8 million, $.22 a share for the first nine months of 2015. Net cash provided by operating activities for 2016’s third quarter was $8.3 million, compared to $9 million in the third quarter of 2015. For the nine months ended September 30, 2016, net cash provided by operating activities was $28.3 million compared to $23.6 million for the first nine months of 2015.

Commenting on the results, “Deltic delivered another solid quarter of operating and financial results driven by its exceptional asset base and people,” said interim President and Chief Executive Officer, D. Mark Leland. “We continued to capitalize on an improved lumber market while maintaining our market share. Average sales price on lumber sales in the Manufacturing segment was 17 percent higher when compared to this time last year. In addition, both operating and financial performance at our MDF plant continued to improve as a result of our team’s successful efforts to reduce unscheduled downtime and associated unplanned maintenance expense. Progress continues on the new small-log line at our Ola Mill and it is expected to be operational in December, allowing us to optimize smallwood harvested in our plantation thinning operations. We harvested more pine sawtimber during the third quarter and are on track to achieving our annual harvest plan in the Woodlands segment. Even though the pine

pulpwood harvest increased 41%, prices have softened. In our Real Estate segment, we continued to close on the sale of new lots developed in 2016. On October 19, we offered 45 lots for sale in Chenal Valley and they were all put under contract with builders, and are scheduled to close before year-end. We are currently developing additional lots in our Wildwood Place development, and plan to offer them for sale either later this year or early in 2017.”

The Woodlands segment reported operating income of $4.1 million for the third quarter of 2016, compared to $4.5 million in 2015’s third quarter. The pine sawtimber harvest in the third quarter of 2016 was 188,643 tons, a five percent increase from the 179,376 tons harvested during the third quarter of 2015. The average per-ton sales price for pine sawtimber in 2016’s third quarter was $28, a four percent increase from the $27 per ton received during the third quarter of 2015. During the third quarter of 2016, Deltic harvested 129,122 tons of pine pulpwood, a 41 percent increase when compared to 2015’s third quarter harvest of 91,905 tons. The average per-ton sales price received for the pine pulpwood harvested in the third quarter of 2016 was $7, a decrease of 22 percent when compared to $9 per ton for the third quarter of 2015. The total increase in the harvest volume for pine sawtimber and pulpwood was mainly due to the timing of Deltic’s annual harvest plan, the mix of timber on the tracts that were being harvested, ongoing pine plantation thinning activity, and good logging conditions in the Company’s operating region. Oil and gas lease rental and royalty income totaled $.4 million in the third quarter of 2016 versus $.7 million for the same period of 2015. The decrease was primarily due to lower natural gas prices received for the Company’s royalty share of gas production, combined with the impact of declining natural gas production from aging existing gas wells and a lack of new drilling activity due to the low natural gas prices. During the current quarter, Deltic had no sales of timberland, compared to sales of 2 acres of non-strategic timberland at an average sales price of $4,300 per acre in 2015’s third quarter.

The Manufacturing segment reported operating income of $5.7 million for the third quarter of 2016, compared to $2 million in 2015’s third quarter. The increase was primarily due to a higher average sales price for lumber, partially offset by the impact of an increased cost for the logs used as raw material in Deltic’s sawmills that resulted from rising pine sawtimber prices. MDF operations experienced reduced unscheduled maintenance downtime and related unplanned maintenance expenses during the third quarter of 2016, resulting in a lower average per-unit manufacturing cost for the MDF produced. During

the third quarter of 2016, the Company’s sawmills sold 69.6 million board feet of lumber, compared to sales of 71.2 million board feet during the third quarter of 2015. The average lumber sales price was $376 per thousand board feet in the third quarter of 2016, a 17 percent increase from the $321 per thousand board feet reported in the third quarter of 2015. In the third quarter of 2016, Deltic sold 26 million square feet of MDF, a two percent increase when compared to sales of 25.5 million square feet in the third quarter of 2015. The average sales price of MDF during 2016’s third quarter was $561 per thousand square feet, compared to the average sales price of $557 per thousand square feet sold in the third quarter of 2015. During the current-year third quarter, the Company continued to manage the number of operating hours in its manufacturing facilities in its ongoing effort to match production of both lumber and MDF with market demand, and will continue to do so in future periods.

The Real Estate segment reported an operating loss of $.2 million for the third quarter of both 2016 and 2015. There were 25 residential lots sold in the third quarter of 2016 versus 34 lots sold in 2015’s third quarter. Due to the mix of residential lots sold, the current quarter’s average per-lot sales price was $70,000 compared to an average sales price of $62,700 per lot in the third quarter of 2015. There were no sales of commercial acreage during either 2016’s or 2015’s third quarter.

Corporate operating expense was $5.4 million in the third quarter of 2016 compared to $3.7 million for the third quarter of 2015. The increase was due to higher general and administrative expenses, primarily incentive plan expenses and professional fees. Interest expense was $2.2 million in the third quarter of 2016 compared to $1.9 million in the third quarter of 2015. The increase was mainly due to a higher debt level resulting from borrowings during the fourth quarter of 2015 and the first quarter of 2016 to fund both a portion of capital expenditures and share repurchases, combined with the impact of a higher weighted-average interest rate on the debt outstanding. Income tax expense in 2016’s third quarter was $.9 million for the period compared to $.1 million in the prior-year’s third quarter. The increase was the result of higher pretax income, partially offset by a benefit of a lower effective income tax rate due to gains from timber harvesting activity being taxed at a capital gains rate for the year of 2016.

Capital expenditures were $14.8 million in 2016’s third quarter and $33.8 million for the first nine months of 2016. Capital expenditures for the corresponding periods of 2015 were $11.1 million and

$25.1 million, respectively. There were timberland acquisition expenditures of $.5 million in the third quarter of 2016, while there were $1.2 million of such expenditures in the first nine months of 2016. For the corresponding periods of 2015, there were no timberland acquisition expenditures and $.6 million, respectively.

For the first nine months of 2016, the pine sawtimber harvest was 598,024 tons compared to 600,390 tons during the same period of 2015, while the average pine sawtimber sales price of $28 per ton increased $1 per ton from the prior-year period. The pine pulpwood harvest for the first nine months of 2016 increased 29 percent, to 392,520 tons, when compared to 304,037 tons in the first nine months of 2015. The average sales price for pine pulpwood sold in the first nine months of 2016 was $8 per ton, compared to $10 per ton in the prior year. Oil and gas lease rental and royalty income were $1.1 million in the first nine months of 2016 versus $2.8 million in the first nine months of 2015. Sales of timberland for 2016’s first nine months totaled 9 acres at an average sales price of $4,400 per acre, while in the same period of 2015 Deltic sold 60 acres for an average per-acre sales price of $2,400. Lumber sales volume increased nine percent, from 194.4 million board feet in 2015 to 211.1 million board feet in the first nine months of 2016, while the average sales price for lumber increased six percent, from $341 per thousand board feet in 2015 to $362 per thousand board feet for the first nine months of 2016. MDF sales volume was 79.7 million square feet in 2016’s first nine months, a 10 percent increase from 72.4 million square feet sold in the same period of 2015, while the average sales price for MDF decreased from $565 per thousand square feet for the first nine months of 2015 to $556 per thousand square feet for the same period in 2016. During the first quarter of 2015, there was a fire at the Company’s MDF plant that caused production downtime at the MDF facility and resulted in a decreased sales volume for the first nine months of 2015. Residential lot sales for the first nine months of 2016 totaled 53 lots at an average sales price per lot of $79,900, compared to 48 lots at $63,900 per lot for the same period of 2015. The Company sold 10.8 acres of commercial real estate at an average of $152,500 per acre during the first nine months of 2016 while there were no commercial acreage sales in the first nine months of 2015.

Concerning the outlook for the fourth quarter and year of 2016, Mr. Leland stated, “We currently anticipate the pine sawtimber harvest to be 135,000 to 165,000 tons and 733,000 to 763,000 tons, respectively. Finished lumber production and sales volume are estimated at 65 to 75 million board feet

for the fourth quarter and 276 to 286 million board feet for the year. MDF sales volumes for the fourth quarter and year of 2016 are forecast to be 20 to 30 million square feet and 100 to 110 million square feet, respectively. Actual sales volumes for both finished lumber and MDF are dependent upon market conditions. Residential lot sales are projected to be 50 to 70 lots and 103 to 123 lots for the fourth quarter and year of 2016, respectively. Commercial acreage within Chenal Valley continues to receive interest from potential buyers, even so it is difficult for the Company to predict the timing of closings of any commercial real estate transactions due to their highly uncertain nature, volatility, and the significant number of factors related to any sale. The financial results for the fourth quarter of 2016 will also include a one-time, pretax expense of approximately $3 million related to the recent retirement of Ray C. Dillon as Deltic’s President and CEO, inclusive of the cash payment made to him upon his retirement and of the financial impact of vesting the equity grants previously awarded to him.”
