Exhibit 99.1

   LSB INDUSTRIES, INC. REPORTS RESULTS FOR THE QUARTER ENDED MARCH 31, 2006,
          AND DATE FOR CONFERENCE CALL TO DISCUSS FIRST QUARTER RESULTS

    OKLAHOMA CITY, May 8 /PRNewswire-FirstCall/ -- LSB Industries, Inc. (Amex:
LXU), reported net income before preferred stock dividends of $2.6 million for
the three months ended March 31, 2006.

    Results for three months ended March 31, 2006
    ---------------------------------------------

    Net sales from continuing operations for the three months ended March 31,
2006 and 2005 were $111.7 million and $86.7 million, respectively, an increase
of $25.0 million or 28.9%.

    For the three months ended March 31, 2006, the Company reported net income
of $2.6 million before preferred stock dividends. After deducting dividend
requirements for preferred stocks the 2006 net income applicable to common stock
was $2.0 million or $.12 per share fully diluted. For the quarter ended March
31, 2005, net income was $1.4 million. After deducting dividend requirements for
preferred stocks, which were not declared or paid, the 2005 net income
applicable to common stock was $.9 million, or $.06 per share fully diluted.

    Commenting on results Barry Golsen, President of LSB, made the following
comments:

    Both of our businesses reported higher sales in the first quarter 2006
compared to the first quarter of 2005.

    Our Climate Control Business continued to grow in sales and profitability.
Sales were up 33% to $47.2 million. Operating income increased to $5.6 million,
up from $2.4 million in 2005.

    Incoming orders were strong. The backlog of confirmed customer orders as of
March 31, 2006 was $70.2 million as compared to $56.2 million at December 31,
2005. Our Climate Control Business is increasing its manufacturing capacity to
accommodate its current increased level of business.

    Our Chemical Business' net sales were $62.5 million compared to $49.9
million, an increase of 25% compared to the same quarter in 2005. Operating
income was $1.4 million compared to $1.6 million in the first quarter 2005.

    The first quarter 2006 operating results of the three separate facilities
that comprise our Chemical Business varied considerably. The Baytown, Texas and
El Dorado, Arkansas operating results for the first quarter of 2006 were
significantly improved over 2005. On the other hand, the Cherokee, Alabama
facility reported an operating loss of $1.6 million in the first quarter of 2006
compared to an operating income of $.6 million for the same period last year.



    The significant swing in results at Cherokee was related to disruption at
the plant caused by the sudden and record climb in natural gas costs beginning
in August 2005, primarily due to the hurricanes in the US Gulf. Cherokee
suspended production in December 2005 and did not resume production until mid
January 2006, and then only at two-thirds normal production rates. Natural gas
prices continued to be well above historical averages throughout the first
quarter of 2006.

                              LSB Industries, Inc.
                     Notes to Unaudited Financial Highlights
                   Three Months Ended March 31, 2006 and 2005
                                   (unaudited)

Note 1:   Beginning in October 2004 and continuing into June 2005, the Chemical
          Business' results were adversely affected as a result of the loss of
          production due to a mechanical failure of one of the four nitric acid
          plants at the El Dorado Facility. The plant was restored to normal
          production in June 2005. For the three months ended March 31, 2006, we
          realized insurance recoveries of $554,000 relating to business
          interruption insurance claims which are recorded as a reduction to
          cost of sales.

Note 2:   Included in non-operating other income net for the first three months
          of 2005 is $1.1 million in insurance proceeds net of benefit
          obligations recognized from certain key man life insurance policies
          upon the death of one of the Company's executives.

Note 3:   Net income applicable to common stock is computed by adjusting net
          income by the amount of preferred stock dividends. Basic net income
          per common share is based upon net income applicable to common stock
          and the weighted average number of common shares outstanding during
          each period. Diluted income per share is based on net income
          applicable to common stock plus preferred stock dividend requirements
          on preferred stock assumed to be converted, if dilutive, and interest
          expense including amortization of debt issuance costs, net of income
          taxes, on convertible debt assumed to be converted and the weighted
          average number of common shares and dilutive common equivalent shares
          outstanding, if any, and the assumed conversion of dilutive
          convertible securities outstanding, if any.

Note 4:   During the first quarter of 2006, the Board of Directors declared a
          dividend of $.10 per share on the Company's $3.25 Convertible
          Exchangeable Class C Series 2 Preferred Stock, a $.31 per share
          dividend on the Company's Non-Cumulative Preferred Stock, and a $.37
          per share dividend on the Company's Series B 12% Cumulative,
          Convertible Preferred Stock. These dividends were paid on March 15,
          2006 to shareholders of record on February 15, 2006. These dividends
          have been declared on a pro-rata basis. These dividends do not reduce
          the amount of previously accrued unpaid dividends.

Note 5:   Information about the Company's operations in different industry
          segments for the three months ended March 31, 2006 and 2005 is

Notes:

    Gross profit by industry segment represents net sales less cost of sales.
Gross profit classified as "Other" relates to industrial machinery and
components.

    Our chief operating decision makers use operating income (loss) by industry
segment for purposes of making decisions which include resource allocations and
performance evaluations.

    Operating income (loss) by industry segment represents gross profit by
industry segment less selling, general and administrative expenses ("SG&A")
incurred by each industry segment plus other income and other expense
earned/incurred by each industry segment before general corporate expenses and
other business operations, net. General corporate expenses and other business
operations, net consist of unallocated portions of gross profit, SG&A, other
income and other expense.

    General corporate expenses and other business operations, net are not
allocated to our Climate Control and Chemical Businesses since these items are
not included in the operating results reviewed by our chief operating decision
makers for purposes of making decisions as discussed above.
