(Unaudited,
except for December 31, 2005)

Note 1  Interim Financial Statements

The interim financial information included herein is unaudited; however, such information reflects all adjustments which are, in the opinion of
management, necessary for a fair presentation of the Companys financial position, results of operations, and cash flows for the interim periods. All such adjustments are of a normal, recurring nature. The results of operations for the first
nine months of the year are not necessarily indicative of the results of operations which might be expected for the entire year.

The
financial statements in Deltics 2005 annual report on Form 10-K include a summary of significant accounting policies of the Company and should be read in conjunction with this Form 10-Q. Certain prior period amounts have been reclassified to
conform with the 2006 presentation format.

Note 2  Impact of Recently Effective Accounting Pronouncements

The Company adopted Statement of Financial Accounting Standards (SFAS) No. 123 (R), Share-Based Payment, effective January 1, 2006.
(For additional information regarding the adoption of SFAS No. 123 (R), see Note 4  Stock-Based Compensation.)

In March 2006,
the Financial Accounting Standards Board (FASB) issued SFAS No. 156, Accounting for Services of Financial Assets. This statement amends SFAS No. 140, Accounting for Transfers and Servicing of Financial Assets and
Extinguishments of Liabilities. The effective date of SFAS No. 156 is generally as of the start of the first fiscal year beginning after September 15, 2006. The Company does not expect the adoption of SFAS No. 156 to have a material
effect on its consolidated financial statements.

In June 2006, the FASB issued Interpretation No. 48, Accounting for Income Tax
Uncertainties. This interpretation prescribes a recognition threshold and measurement attribute for the financial statement recognition measurement of a tax position taken or expected to be taken in a tax return. The effective date of FASB
Interpretation No. 48 is generally as of the start of the first fiscal year beginning after December 15, 2006. The Company does not expect the adoption of FASB Interpretation No. 48 to have a material effect on its consolidated
financial statements.

In September 2006, the FASB issued SFAS No. 157, Fair Value Measurements. This statement applies when other
accounting pronouncements require fair value measurements; it does not require new fair value measurements. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007, and interim periods
within those years. The Company does not expect the adoption of SFAS No. 157 to have a material effect on its consolidated financial statements.

In September 2006, the FASB issued SFAS No. 158, Employers Accounting for Defined Benefit Pension and Other Postretirement Plans, an amendment of FASB Statements No. 87, 88, 106, and 132 (R). The
effective date of SFAS No. 158 is for fiscal years ending after December 15, 2006. The Company will be required to use the prospective transition method upon adoption. The Company plans to adopt the provisions of SFAS No. 158 as of
the fiscal year ending December 31, 2006, and the measurement date provisions as of December 31, 2008. Had SFAS No. 158 been in effect for the year ended December 31, 2005, the Company would have shown a liability for pension
funding of $5,063,000 net of incremental taxes and a reduction in the Accumulated Other Comprehensive Income portion of Stockholders Equity of $5,063,000.

In September of 2006, the SEC staff issued Bulletin No. 108, Considering the Effects of Prior Year Misstatements in Current Year Financial Statements. The effective date to apply the provisions of
Staff Accounting Bulletin (SAB) No. 108 is no later than the annual financial statements for Deltics first fiscal year ending after November 15, 2006. SAB No. 108 was issued in

Note 4  Stock-Based Compensation

Deltic currently has a stock incentive plan that allows the Company to grant (1) stock options, (2) restricted stock and restricted units,
(3) performance units, and (4) other stock-based awards to executives, other key employees, and nonemployee directors. This plan replaced the Companys previous stock incentive plan in 2002. No further awards will be made under the
previous plan. These plans are discussed in more detail in Note 13  Incentive Plans in Deltics 2005 annual report on Form 10-K.

On January 1, 2006, the Company adopted SFAS No. 123 (R), which requires companies to account for share-based payment transactions using a fair value-based method and recognize the related expense in the results of operations.
Prior to the adoption of SFAS No. 123 (R), as permitted by SFAS No. 123, Deltic accounted for share-based payments to employees using the recognition and measurement principles of the Accounting Principles Boards Opinion
(APB) No. 25, Accounting for Stock Issued to Employees, and the related interpretations in accounting for those plans. Share-based employee compensation expense was accrued for the intrinsic value, if any, of stock options or
restricted stock granted over the applicable vesting periods using the straight-line method. Options granted by the Company have an exercise price equal to the market value of the underlying common stock on the date of grant. SFAS No. 123
(R) allowed companies to choose one of two transition methods: (1) the modified prospective transition method or (2) the modified retrospective method. The Company chose to use the modified prospective transition methodology and,
accordingly, Deltic has not restated the results of prior periods.

Note 4  Stock-Based Compensation (cont.)

Under the fair value recognition provisions of SFAS No. 123 (R), stock-based compensation cost is estimated at the grant date based on the fair value
of the award and is recognized as expense over the requisite service period of the award. For valuation of stock options granted subsequent to the adoption of SFAS No. 123 (R), Deltic elected to use a binomial model to estimate fair value. The
fair value of restricted stock awards is determined by reference to the fair market value of the Companys common stock on the date of grant. For restricted stock performance units subsequent to Deltics adoption of SFAS No. 123 (R),
the Monte Carlo simulation is being used to estimate fair value. For all awards subsequent to the adoption of SFAS No. 123 (R), the Company will recognize compensation cost on a straight-line basis over the requisite service period.

Determination of the appropriate fair value model and related assumptions requires estimates of stock price volatilities, forfeiture rates, and
expected option terms. The expected volatility rates are estimated based on the historical and implied volatilities of Deltics common stock. The expected option term represents the average time that options that ultimately vest are expected to
be outstanding and is based on the vesting provisions and historical exercise, cancellation, and expiration patterns. The Company estimates pre-vesting forfeitures when recognizing compensation based on historical rates and forward-looking factors.
These assumptions will be updated at least on an annual basis and on an interim basis if significant changes to the assumptions are warranted.

Deltic issues restricted stock performance units whose vesting is contingent upon meeting certain financial performance goals based upon the Companys total stockholder return compared to the total return of a Paper and Forest Products
Index (the Index) selected by the Compensation Committee and calculated by Standard and Poors. Determining the appropriate amount to expense is based on likelihood of achievement of the stated goals and requires judgement,
including forecasting future financial results. This estimate is revised periodically based on the probability of achieving the required performance targets and adjustments are made as appropriate. The cumulative impact of any revision is reflected
in the period of change. If the financial performance goals are not met, no compensation cost is required and any previously recognized compensation cost is reversed.

The adoption of SFAS No. 123 (R) had an impact on the Companys results of operations. The Consolidated Statement of Income for the three months and nine months ended September 30, 2006, included
$306,000 and $901,000, respectively, of stock-based compensation expense reflected in General and Administrative Expenses.

SFAS
No. 123 (R) requires the benefits of tax deductions in excess of recognized compensation cost to be reported as a financing cash flow, rather than as an operating cash flow as required under APB 25 and related interpretations. This
requirement increased net financing cash flows, rather than net operating cash flows, for the nine months ended September 30, 2006 by $496,000. The cumulative effect related to outstanding restricted stock awards as of December 31, 2005,
which are not expected to vest based on an estimate of forfeitures, was not material.

Assumptions for the 2006 and 2005 valuation of stock
options and restricted stock performance units consisted of the following:

Note 4  Stock-Based Compensation (Cont.)

The expected volatility rate was estimated based on equal weighting of the historical volatility of Deltic common stock over the nine-year trading life
and the implied volatilities of Deltic common stock. The expected term was estimated based on the Companys historical experience of exercise, cancellation, and expiration patterns. The risk-free interest rates are based on the rate for U.S.
Treasury zero coupon bonds over the term of the option. The expected dividend yield is Deltics average dividend yield from 2002 to 2005.

The pre-vesting forfeiture rate used for the nine months ended September 30, 2006, was 4.5 percent, which was based on historical rates and forward-looking factors. As required under SFAS No. 123 (R), over time the Company will
adjust the estimated forfeiture rate to agree with actual experience.

For the three months and nine months ended September 30, 2005,

(MDF) plant near El Dorado, Arkansas, during 1998.

Prior to August 26, 2004, the Company had agreed to a contingent equity
contribution agreement with Del-Tin Fiber and the group of banks from whom Del-Tin Fiber had obtained its $89,000,000 credit facility. Under this agreement, Deltic and the other 50 percent owner of the joint venture had agreed to fund any deficiency
in contributions to either Del-Tin Fibers required sinking fund or debt service reserve, up to a cumulative total of $17,500,000 for each owner. In addition, each owner had committed to a production support agreement, under which each owner
had agreed to make support obligation payments to Del-Tin Fiber to provide, on the occurrence of certain events, additional funds for payment of debt service until the plant was able to successfully complete a minimum production test. Both owners
had also agreed, in a series of one-year term commitments, to fund any operating working capital needs until the facility was able to consistently generate sufficient funds to meet its cash requirements.

Note 6  Investment in Del-Tin Fiber (cont.)

On August 26, 2004, Del-Tin Fiber refinanced its existing long-term debt by entering into a credit agreement consisting of a letter of credit and
term loan with multiple lending institutions. The funds provided from this credit agreement were used, together with the existing balance in Del-Tin Fibers debt service reserve and bond sinking fund accounts, to redeem $60,000,000 of its
$89,000,000 industrial revenue bonds. Under the new credit agreement, the lenders, on September 1, 2004, loaned Del-Tin Fiber $30,000,000, repayable over five years in equal quarterly installments, beginning December 31, 2004, and issued
on Del-Tin Fibers behalf, a letter of credit in the amount of $29,689,000 to support the remaining industrial revenue bonds originally issued in 1998 by Union County, Arkansas. Concurrent with this event, on August 26, 2004, Deltic
executed a guarantee agreement in connection with the refinancing of the debt of Del-Tin Fiber. Under Deltics guarantee agreement, Deltic unconditionally guarantees the due and punctual payment of 50 percent ($23,500,000 at September 30,
2006) of Del-Tins obligations under its credit agreement. This new credit agreement of Del-Tin Fiber fully replaces Del-Tin Fibers prior credit facility, resulting in Deltics previous contingent equity contribution agreement of
$17,500,000, the production support agreement, and the need for the series of one-year operating working capital commitments being fully extinguished.

The Company has adopted the provisions of FASB Interpretation No. 45, Guarantors Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others, an
interpretation of FASB Statements No. 5, 57 and 107 and a rescission of FASB Interpretation No. 34 (FIN 45). In accordance with FIN 45, Deltic estimated the fair value of its guarantee of Del-Tin Fibers credit agreement
to be $3,450,000 and included this non-cash amount in the Companys Consolidated Balance Sheet as a long-term liability with an offsetting increase in the Companys investment in Del-Tin Fiber. Deltic is reducing this liability
systematically over the life of the credit agreement, as the Company is released from risk under the guarantee. Simultaneously, the offsetting amount which represents the difference between the Companys recorded investment in Del-Tin Fiber and
its underlying equity in the net assets of the joint venture is being amortized over the same period as the guarantee. The amortization of the guarantee and the basis difference are netted for purposes of financial reporting and result in no net
income statement effect. At September 30, 2006, Deltics unamortized balance related to the value of the guarantee was $2,070,000.

The financial position for Del-Tin Fiber as of the balance sheet dates and results of operations for the periods ended September 30 consisted of the following:

For the nine months ended September 30, 2006 and 2005, the Company recorded $3,924,000 and
$1,814,000 in mineral lease bonus receipts, which were recorded in cash flows provided by operating activities. Of this amount, $859,000 and $383,000 were included in cash flows provided by changes in operating working capital other than cash for
the nine months ended 2006 and 2005, respectively, and $2,784,000 and $1,353,000 were included in cash flows provided by other operating activities for the nine months ended 2006 and 2005, respectively.

Note 11  Income Taxes

Income tax expense was
$3,314,000 for the third quarter of 2006 and $8,000 for the third quarter of 2005, resulting in effective income tax rates of 35 percent and zero percent for the 2006 and 2005 periods respectively. The lower income tax expense during the third
quarter of 2005 was due to an income tax benefit created by the impact of the reversal of a $1,686,000 estimated valuation allowance related to accumulated state net operating loss carryforwards. In 2005, based on projections of increased future
taxable income, it was more likely than not that the future benefits of those state net operating losses would be utilized in their entirety. The non-cash income tax benefit resulting from the reversal of that estimated valuation allowance amounted
to $1,096,000, $.09 per share, for the third quarter of 2005. Before recording the reduction in the valuation allowance, the Companys effective income tax rate for the third quarter of 2005 was 34 percent. The lower effective tax rate for the
third quarter of 2005, when compared to the third quarter of 2006, was due to lower effective rates for state income taxes in the third quarter of 2005.

Income tax expense was $7,484,000 for the first nine months of 2006 and $4,836,000 for the first nine months of 2005, resulting in effective income tax rates of 37 percent and 28 percent for the 2006 and 2005 periods
respectively. The reduction in income tax expense during the first nine months of 2005 was due to an income tax benefit created by the impact of the reversal of a $2,612,000 estimated valuation allowance related to accumulated state net operating
loss carryforwards. The non-cash income tax benefit resulting from the reversal of this estimated valuation allowances amounted to $1,697,000, $.14 per share, for the first nine months of 2005. Before recording that reduction in the valuation
allowance, the Companys effective income tax rate for the first nine months of 2005 was 38 percent.

Note 12  Contingencies

During 2004, the Company disclosed its plans for a 1,170-acre, 187 lot, upscale residential development, The Ridges at Nowlin Creek, on a portion of Deltics large land holdings located west of Little Rock,
Arkansas. A portion of the development is located within the watershed of Lake Maumelle, a principal source of drinking water for the City of Little Rock. On September 19, 2005, the local water utility filed a petition in the Circuit Court of
Pulaski County, Arkansas, to condemn that portion of the development within the lakes watershed, and deposited $3,830,000 as its estimate of just compensation for the land taken. The utility has subsequently amended the legal description of
the land it seeks to condemn and has raised its estimate of just compensation to $5,100,000. The condemned property, as amended, includes 99 lots, parts of an additional 20 lots, proposed access to seven lots, and approximately 40 acres of watershed
land that is not a part of The Ridges at Nowlin Creek.

Upon application by Deltic, on October 11, 2005, the utilitys initial
deposit of $3,830,000 was transferred into the Companys bank account. Deltic has initiated proceedings to have a jury determine the true amount of just compensation for the lands, as well as bringing before the Court a challenge to the
propriety of the action. The court hearing regarding Deltics challenge to the propriety of the action is scheduled to begin in December 2006, with the trial as to the proper amount of just compensation anticipated for 2007, should the
propriety of the action be upheld. Under Arkansas statutes, as interpreted by its courts, condemnation proceedings of this nature by a municipal utility, do not vest fee simple title to the land, until the utility pays the final judgement of just
compensation in the case. Should the utility decide not to pay the final judgement, possession and full title is returned to Deltic and the utility is liable for damages during the period Deltic is dispossessed of its property and legal fees.

Due to this contingent component of the transaction, no gain will be recorded in the Companys Consolidated Statement of Income unless
fee simple title of the property is transferred from the Company. As a result of the October 11, 2005 deposit of the $3,830,000 into Deltics bank account, a long-term deferred revenue liability equal to these cash proceeds received are
included in the Companys Consolidated Balance Sheet in Other Noncurrent Liabilities ended September 30, 2006.

Item 2. Managements Discussion and Analysis of Financial Condition and Results of Operations

Executive Overview

The Company recorded net income of $6.3 million for the third quarter of 2006 compared to $3.3 million for the same period of 2005.
Deltics Woodlands segment provided $4.6 million in operating income during the third quarter. The Companys Mills segment reported an operating loss of $3.6 million in 2006s third quarter, compared to income of $1.7 million in the
corresponding quarter of 2005. Finished lumber sales prices continued to decline in the third quarter of 2006, and the price per thousand board feet (MBF) dropped $80, or 21 percent, to $294. Lumber sales volumes decreased from 64.9 MBF
in the third quarter of 2005 to 63.2 MBF for the same period in 2006. This reduction in sales is due to the elimination of an operating shift at the Companys Ola Mill and scheduled outages for capital improvements at the Ola and Waldo Mills
during the third quarter of 2006. The Real Estate segment earned $11 million in operating income for the third quarter of 2006, compared to $.4 million for the same quarter of 2005. Commercial sales provided a $10.7 million margin in the third
quarter compared to no commercial sales for the same period of 2005. Residential lot sales totaled 23 lots, a decrease of eight when compared to the third quarter of 2005. The average lot price of $104,300 increased $21,700 per lot, or 26 percent,
due primarily to sales mix. Deltic owns a 50 percent interest in Del-Tin Fiber L.L.C., and Deltics share of the joint ventures income for the third quarter of 2006 was $1.5 million compared to $.1 million for the same period in 2005.

Deltic is primarily a wood products producer operating in a commodity-based business environment, with a major diversification in real
estate development. This environment is affected by a number of factors, including general economic conditions, interest rates, imports, foreign exchange rates, housing starts, residential repair and remodeling, commercial construction, industry
capacity and production levels, the availability of raw material, and weather conditions. During the second half of 2005 and first part of 2006, the Federal Reserve steadily increased the Federal Funds Rate in an effort to gradually slow economic
growth and hold inflation in check. These increases, as well as other inflationary factors, have slowed housing starts in 2006. Consequently, the high demand and pricing levels for softwood lumber products experienced during 2004 and 2005 have been
declining to near 10 year record lows for some dimensions during 2006. Given its relative size and the nature of most commodity markets, the Company has little or no control over pricing levels for its wood. Therefore, the Company will continue to
focus on increasing efficiencies and reducing controllable manufacturing cost. Sales of real estate are affected by general economic conditions and interest rates, specifically as such factors are manifested in the Companys operating area of
central Arkansas. The economic conditions, volume of housing inventory, and mortgage interest rates have impacted the housing market causing a reduction in Deltics residential lot sales for 2006.

For the third quarter of 2006, pine sawtimber harvest levels decreased 37,876 tons, to 121,636 tons, when compared to the third quarter of 2005. Pine
sawtimber harvest levels for the nine months ending September 30, 2006 increased one percent, to 489,358 tons, when compared to the same period of last year; however, the Company plans to keep 2006s total pine sawtimber harvest volume
comparable to the level in 2005. Ultimately, the Companys ability to sell pine sawtimber at acceptable prices in the future will be dependent upon the size or existence of markets for manufactured lumber and other wood products. Activities to
sell timberland identified as having a higher and better use or as being non-strategic remain in place. However, Deltic continues to consider these sales only to the extent that the returns on these transactions meet increased expectations.
Timberland designated as higher and better use consists of tracts with market values that exceed the lands worth as a timber growing platform. Non-strategic timberland consists primarily of tracts too small to allow efficient timber
management, those geographically isolated from other Company fee lands, and acreage otherwise not deemed strategic to Deltics operations or growth.

Recent advances in technology and increased pricing levels for natural gas have resulted in the economic viability of expanded natural gas exploration within the state of Arkansas. One current area of activity, known
as the Fayetteville Shale Play, is an unconventional natural gas reservoir spread across multiple Arkansas counties. During the first nine months of 2006, Deltic leased natural gas drilling rights on approximately 11,000 net mineral
acres within the boundaries of the Fayetteville Shale Play area as

currently defined by the Arkansas Oil & Gas Commission. When combined with similar leases from 2005, the total net mineral acres leased to-date is
just over 26,000 acres. The Company has leased most of its net mineral acres within the Fayetteville Shale Play, as currently defined by the Arkansas Oil & Gas Commission. The ultimate benefit to Deltic from these mineral leases is
contingent on the successful extraction and sale of natural gas from the area.

The Mills segment has encountered a declining lumber
market which caused the average sales price per MBF to decrease $80, or 21 percent, to $294 in the third quarter of 2006, from the third quarter 2005 average of $374 per MBF. The average sales price for the first nine months of 2006 is down $44 per
MBF from the corresponding period in 2005 to an average of $333 per MBF. In response to lower prices and decreased demand, management has eliminated an operating shift at the Ola Mill. The Ola Mill is undergoing the final step of a capital upgrade
program, which management believes will help the mills future operations by maximizing hourly productivity levels with the smaller log size available as raw material for this mill. The Company remains pleased with the Waldo Mills
improved efficiencies and lower operating costs per MBF when compared to the first nine months of 2005. As with any commodity market, the Company expects the historical volatility of lumber prices to continue in the future. The Company continues to
anticipate that a significant percentage of logs supplied to both of its sawmills will come from strategically located Company fee timberlands.

The Real Estate segment closed the sale of 23 residential lots during the third quarter, a reduction of eight residential lots when compared to the same quarter in 2005. The average sales price per lot increased 26 percent when compared to
the same quarter last year. The reported average sales price for residential lots for a specific period is dependent upon the mix of lot sales in that period. Deltics lot development plans provide for a mix of lot offerings that represent most
real estate market segments for planned communities. Sales activity levels for the Companys real estate developments are affected by economic conditions that influence the level of housing starts in the central Arkansas region, including
general economic conditions, the volume of housing inventory, and interest rates. As previously mentioned, slower economic growth and higher mortgage interest rates in 2006 have lowered the demand for residential lots in the Companys Chenal
Valley development. Appropriately, planned capital expenditures for residential lot development have been reduced for 2006, and the Company does not plan to develop any additional lots within Chenal Valley in 2006 or 2007. The Company sold 10 lots
within the Chenal Valley development during the third quarter of 2006 versus 28 lots during the same period in 2005. There are currently 242 lots available within the Chenal Valley development as of September 30, 2006. In Deltics other
two active developments, Red Oak Ridge and Chenal Downs, a total of 13 lots were sold during the third quarter of 2006 versus three lots during the same period of 2005. There are 69 developed lots in Red Oak Ridge and 16 in Chenal Downs uncommitted
as of September 30, 2006. Chenal Downs is fully developed and Deltic does not plan to develop any additional lots within Red Oak Ridge in 2006 or 2007. Future annual development activity will be dependent upon the demand for the Companys
residential lots.

During 2004, the Company disclosed plans for a 1,170-acre, 187 lot, upscale residential development, The Ridges at
Nowlin Creek, on a portion of its land holdings located within the Highway 10 growth corridor west of Chenal Valley. A portion of the development is located within the watershed of Lake Maumelle, a principal source of drinking water for Little Rock.
Due to this environmentally sensitive locale, the Companys plans include the best management practices using the most modern and proven methods to create a low-impact development in order to protect water quality in the lake. Even though the
local water utility has commissioned the preparation of a new watershed management plan, which supposedly will reflect current scientific principles that would likely be compatible with the Companys low-impact development plans, in 2005, the
utility filed its petition in the Circuit Clerk of Pulaski County, Arkansas, to condemn that portion of the development within the lakes watershed, and deposited its estimate of just compensation for the land taken. The condemned property
includes all of 99 lots, parts of an additional 20 lots, and proposed access to seven lots as well as approximately 40 acres not within the development. Deltic has initiated proceedings to have a jury determine the true amount of just compensation
for the taking of the lands, as well as bringing before the Court a challenge to the propriety of the action. The trial regarding the propriety of the condemnation is scheduled to begin in December, 2006. Under Arkansas statutes, as interpreted by
its courts, condemnation proceedings of this nature by a municipal utility do not vest fee simple title to the land until the utility pays the final judgement of just compensation determined in the case. Should the utility decide not to

pay the final judgement, possession and full title is returned to Deltic and the utility is liable for damages during the period Deltic is dispossessed of
its property, in addition to legal costs incurred by the landowner. The commencement of this action has caused activities at the Ridges at Nowlin Creek development to be postponed pending the outcome of the action. Depending upon the outcome of this
litigation, the Company will need to further assess the viability of proceeding with development of lots at the Ridges at Nowlin Creek. (For further discussion, refer to Note 12 to the consolidated financial statements.)

The Real Estate segment closed the sale of 52.81 acres of commercial property at an average per acre sales price of $246,300 during the third quarter of
2006 compared to no sales during the same period of 2005. Of the 52.81 acres sold during third quarter, approximately 38 acres were sold to an affiliate of RED Development, LLC for development of The Promenade at Chenal, an upscale
lifestyle shopping center. Although commercial real estate sales activity is by nature less predictable than residential activity, the development of The Promenade at Chenal is expected to increase interest in the Companys
additional 135 acres of commercial-zoned property adjacent to the site.

Operating results for Del-Tin Fiber are affected by the overall
medium density fiberboard (MDF) market and the plants operating performance. Del-Tin has benefited from an increase in the overall MDF market price and has continued to successfully increase its percentage of higher priced
thin-board production. The plant has also been able to maintain the operating performance improvement from prior years. For the third quarter of 2006, Deltics share of Del-Tin Fibers net income was $1.5 million compared to $.1 million in
the third quarter of 2005.

Consolidated

The $3 million increase in net income was the result of increased operating income from Deltics Real Estate segment and improved results at Del-Tin
Fiber, partially offset by decreased operating income from Deltics Woodlands and Mills segments and increased income tax expense.

Operating income increased $4.6 million. The Woodlands segment decreased $1.4 million due primarily to a decreased pine sawtimber harvest level and a decreased average per ton sawtimber price. Deltics Mills segment operations
decreased $5.3 million due primarily to reduced sales prices for lumber. The Real Estate segments operating income increased $10.6 million due primarily to commercial acreage sales. Corporate operating expense decreased by $.1 million.

Total net sales decreased $1.6 million, which was mainly driven by decreased sales volume and
lower average sales prices for pine sawtimber, hardwood sawtimber, and hardwood pulpwood, partially offset increases in sales volume for pine pulpwood, lease income, and freight revenue. The reduction in pine sawtimber sales volume was due to the
Companys decision to accelerate the harvest level in the first half of the year when prices were stable in anticipation of downward pressure from a weakened lumber market, and to harvest less in the second half of the year. Operating income
decreased by $1.4 million due to the decrease in net sales combined with increases in freight expense and cost of fee timber harvested, partially offset by a $.8 million reduction in cull timber removal expense due to a delay in the start of the
cull timber removal program in 2006, as a result of a shortage of qualified application contractors.

decreased $1.4 million to $5.4 million. The decrease was due to decreases in both the volume and price of logs coming into Deltics sawmills from the Companys fee timberlands. Logs supplied by the Woodlands segment to the Companys
sawmills are transferred at prices that approximate market.

Equity in Del-Tin Fiber

For the third quarter of 2006, equity in Del-Tin Fiber increased $1.4 million. The increase in income was due primarily to an increased average sales
price and to an increase in the percentage of higher priced thin-board production.

Income Taxes

The Companys effective income tax rate was 35 percent in the 2006 period, while there was virtually no income tax expense for the same period in
2005. The low amount of income tax expense during the third quarter of 2005 was due to the impact of an income tax benefit created by a reversal of the estimated valuation allowance related to accumulated state net operating loss carryforwards.
Based on the 2005 projections of increased future taxable income, it was more likely than not that the future benefits of those state net operating losses would be utilized in their entirety. Before recording the reduction in the valuation
allowance, the Companys effective income tax rate for the third quarter of 2005 was 34 percent. The increase in this effective tax rate when compared to the prior year period was due to lower effective rates for state income taxes in the 2005
period.

Consolidated

The $.4 million increase in net income was the result of increased operating income for the Woodlands and Real Estate segments and improved results at Del-Tin Fiber, partially offset by reduced operating income for
the Mills segment, increased Corporate operating expense, and increased income tax expense.

Operating income decreased $.1 million. The
Woodlands segment increased by $.1 million primarily due to increased lease income and decreased cull timber removal expense due to timing, partially offset by increased cost of fee timber harvested. The Mills segment decreased $9.1 million due
mainly to a 12 percent decrease in average lumber sales price. Real Estate operating income increased $8.2 million primarily due to increased commercial acreage sales. Corporate operating expense increased $.7 million due to higher legal fees and
incentive plan expense.

revenue and lease income. Operating income increased $.1 million primarily due to the increase in net sales combined with a $.8 million reduction in cull timber removal expense, partially offset by increased cost of fee timber harvested.

Total net sales decreased $6.6 million, or seven percent, due to a 12 percent lower average lumber
sales price, being partially offset by a five percent increase in sales volume. Total operating income for the Mills declined $9.1 million due to the decrease in net sales combined with the cost to produce the additional volume of lumber sold.

Total net sales increased $9.8 million primarily due to the increase in commercial acres sold,
partially offset by the reduction in the number of residential lots sold. Real Estate operating income increased $8.2 million due primarily to the same factors impacting net sales.

Corporate

The increase in operating
expense for Corporate functions of $.7 million was due to increased general and administrative expenses for legal fees and incentive plan expense related to the adoption of SFAS No. 123 (R).

Eliminations

Intersegment sales of timber from Deltics Woodlands to the Mills segment increased $.7 million to $18.1 million. The increase was mainly due to a higher average price for logs coming into Deltics sawmills
from Company fee timberlands. Logs supplied by the Woodlands segment to the Companys sawmills are transferred at prices that approximate market.

Equity in Del-Tin Fiber

For the first nine months of 2006, equity in Del-Tin Fiber was $2.7 million,
an improvement of $2.6 million over the same period last year. In 2005, Del-Tin experienced a profitable second quarter which was essentially offset by first quarter losses reported by the joint venture, as the facilitys first quarter 2005
operations were hindered by a temporary production curtailment caused by a fire sustained at the plant.

Additional selected financial and
statistical data for Del-Tin Fiber is shown in the following table.



|                                |  |                                 |       |      |

|Net sales (millions of dollars) |  | $                               | 52.7  |      | 40.7 
|Finished production (MMSF)      |  |                                 | 114.6 |      | 101.1
|Board sales (MMSF)              |  |                                 | 116.3 |      | 99.7

Average sales price increased 11 percent due to the improvements in the MDF market, changes in the
plants product mix to include a greater percentage of thin board, and to an increase in premium-grade production.

Income Taxes

The effective income tax rate was 37 percent and 28 percent in the 2006 and 2005 periods, respectively. The lower effective income tax
rate for the first nine months of 2005 was due to the impact of an income tax benefit created by a reversal of the estimated valuation allowance related to accumulated state net operating loss carryforwards. Based on projections of increased future
taxable income in 2005, it was more likely than not that the future benefits of those state net operating losses would be utilized in their entirety. Before recording the reduction in the valuation allowance, the Companys effective income tax
rate for the first nine months of 2005 was 38 percent.

Liquidity and Capital Resources

Cash Flows and Capital Expenditures

Net cash provided by operating activities totaled $42.4 million for the first nine months of 2006 compared to $29.6 million for the same period in 2005. Changes in operating working capital, other than cash and cash equivalents, provided
cash of $12.6 million in the 2006 period and $2 million in 2005. The Companys accompanying Consolidated Statements of Cash Flows identify other differences between net income/(loss) and cash provided by operating activities for each reporting
period.

The net change in purchased stumpage inventory to be utilized in the Companys sawmill operations
required cash of $1 million in 2006 and provided $2 million in 2005. The Company made advances to Del-Tin Fiber of $2.1 million and received cash distributions of $2.9 million, for net receipts of $.8 million during the current period, compared to
net advances to Del-Tin of $1.9 million for the corresponding period of 2005. In 2006, Deltic made repayments of debt of $4.5 million and had no borrowings. In 2005, Deltic borrowed $11.5 million and made repayments of debt of $14.7 million. Deltic
paid dividends on common stock of $2.8 million during the current period, slightly higher than the $2.5 million dividend payments in 2005. In 2006, proceeds from stock option exercises amounted to $1.9 million, an increase of $.5 million when
compared to 2005. In 2006, the Company adopted SFAS 123 (R), which requires the benefits of tax deductions in excess of recognized compensation cost to be reported as a financing cash flow, rather than as an operating cash flow as required under APB
25 and related interpretations. This amount was $.5 million during the 2006 period. For the 2005 period, cash outflows for other-net financing activities consisted primarily of deferred debt issuance costs capitalized during the third quarter; there
were none in 2006.

Financial Condition

Working capital totaled $12.1 million at September 30, 2006, and $7.0 million at December 31, 2005. Deltics working capital ratio at September 30, 2006, was 1.63 to 1, compared to 1.57 to 1 at the
end of 2005. Cash and cash equivalents at the end of the third quarter of 2006 were $18.1 million compared to $1.6 million at the end of 2005. During the first nine months of 2006, total indebtedness of the Company decreased $4.5 million to $70
million. Deltics long-term debt to stockholders equity ratio was .330 to 1 at September 30, 2006, compared to .376 to 1 at year-end 2005.

Liquidity

The primary sources of the Companys liquidity are internally generated funds,
access to outside financing, and working capital. The Companys current strategy for growth continues to emphasize its timberland acquisition program, in addition to expanding lumber production as market conditions allow and developing real
estate at Chenal Valley, Red Oak Ridge and the currently suspended Ridges at Nowlin Creek.

In December 2000, the Companys Board of
Directors authorized a stock repurchase program of up to $10 million of Deltic common stock. As of September 30, 2006, the Company had expended $2.1 million under this program, with the purchase of 96,206 shares at an average cost of $22.34 per
share; no shares have been purchased in 2006 under this program. In its two previously completed repurchase programs, Deltic purchased 479,601 shares at an average cost of $20.89 and 419,542 shares at a $24.68 per share average cost, respectively.

Off-Balance Sheet Arrangements, Contractual Obligations, and Commitments

Prior to August 26, 2004, the Company had agreed to a contingent equity contribution agreement with Del-Tin Fiber and the group of banks from whom
Del-Tin Fiber had obtained its $89 million credit facility. Under this agreement, Deltic and the other 50 percent owner of the joint venture had agreed to fund any deficiency in contributions to either Del-Tin Fibers required sinking fund or
debt service reserve, up to a cumulative total of $17.5 million for each owner. In addition, each owner had committed to a production support agreement, under which each owner had agreed to make support obligation payments to Del-Tin Fiber to
provide, on the occurrence of certain events, additional funds for payment of debt service until the plant was able to successfully complete a minimum production test. Both owners had also agreed, in a series of one-year term commitments, to fund
any operating working capital needs until the facility was able to consistently generate sufficient funds to meet its cash requirements.

On August 26, 2004, Del-Tin Fiber refinanced its existing long-term debt by entering into a credit agreement consisting of a letter of credit and term loan with multiple lending institutions. The funds provided from this credit
agreement were used, together with the existing balance in Del-Tin Fibers debt service reserve and bond sinking fund accounts, to redeem $60 million of its $89 million industrial revenue bonds. Under the new credit agreement, the lenders, on
September 1, 2004, loaned Del-Tin Fiber $30 million which will be repayable over five years in equal quarterly installments, beginning December 31, 2004, and issued on Del-Tin Fibers behalf, a letter of credit in the amount of $29.7
million to support the remaining industrial revenue bonds originally issued in 1998 by Union County, Arkansas. Concurrent with this event, on August 26, 2004, Deltic executed a guarantee agreement in connection with the refinancing of the debt
of Del-Tin Fiber. Under Deltics guarantee agreement, Deltic unconditionally guarantees the due and punctual payment of 50 percent ($23.5 million at September 30, 2006) of Del-Tins obligations under its credit agreement. This credit
agreement of Del-Tin Fiber fully replaces Del-Tin Fibers prior credit facility, resulting in Deltics previous contingent equity contribution agreement of $17.5 million, the production support agreement, and the one-year commitment being
fully extinguished.

The Company has adopted the provisions of FASB Interpretation (FIN) No. 45, Guarantors
Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others, an interpretation of FASB Statements No. 5, 57 and 107 and a rescission of FASB Interpretation No. 34. In accordance with FIN
45, Deltic initially estimated the fair value of its guarantee of Del-Tin Fibers credit agreement to be $3.5 million and included this non-cash amount in the Companys Consolidated Balance Sheet as a long-term liability with an offsetting
increase in the Companys investment in Del-Tin Fiber. Deltic is reducing this liability systematically over the life of the credit agreement, as the Company is released from risk under the guarantee. At September 30, 2006, Deltics
unamortized balance related to the value of the guarantee was $2.1 million.

The Company has both funded and unfunded noncontributory
defined benefit retirement plans that cover the majority of its employees. The plans provide defined benefits based on years of service and final average salary. Deltic also has other postretirement benefit plans covering substantially all of its
employees. The health care plan is contributory with participants contributions adjusted as needed; the life insurance plan is noncontributory. (For information about material assumptions underlying the accounting for these plans and other
components of the plans, refer to Note 12 to the consolidated financial statements included in the Companys 2005 annual report on Form 10-K.)

Outlook

Deltics management believes that cash provided from its operations and the amount available under its credit facility will be sufficient to meet its
expected cash needs and planned expenditures, including those of the Companys continued timberland acquisition and stock repurchase programs, additional advances to Del-Tin Fiber, and capital expenditures, for the foreseeable future.

Critical Accounting Policies and Estimates

Critical accounting policies are defined as those that are reflective of significant judgements and uncertainties and potentially result in materially different results under different assumptions and conditions. The Company has prepared
its consolidated financial statements in conformity with accounting principles generally accepted in the United States, which require management to make estimates and assumptions that affect the reported amounts in these financial statements and
accompanying notes. Actual results could differ from those estimates under different assumptions or conditions. The Company has disclosed its critical accounting policies in its 2005 annual report on Form 10-K, and this disclosure should be read in
conjunction with this Form 10-Q. There have been no changes in these identified critical policies, nor have there been any initially adopted accounting policies having a material impact on reported financial results.

Outlook

Pine sawtimber harvest levels are expected to be 80,000 to 90,000 tons in the fourth quarter of 2006 and 565,000 to 575,000 tons for the year. Finished lumber production and sales volume will continue to be subject to market conditions, and

changed significantly from that set forth under the caption Quantitative and Qualitative Disclosures About Market Risk, in Item 7A of Part II of its 2005 annual report on Form 10-K. Those disclosures should be read in conjunction

Based on their evaluation as of September 30, 2006, the Chief Executive
Officer and Chief Financial Officer of the Company have concluded that the Companys disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934) are effective to ensure that the
information required to be disclosed by the Company in the reports that it files or submits under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms.

Changes in Internal Control Over Financial Reporting

Deltics management, with the Chief Executive Officer and Chief Financial Officer, have evaluated any changes in the Companys internal control over financial reporting that occurred during the

control over financial reporting.
