UNITED STATES LIME & MINERALS REPORTS
RECORD SECOND QUARTER 2006 RESULTS

Dallas, Texas, July 27, 2006 — United States Lime & Minerals, Inc. (NASDAQ: USLM) today reported record second quarter 2006 results: Revenues increased to $31,934,000 from $21,582,000 in the comparable prior year quarter, an increase of $10,352,000, or 48.0%. Revenues from the Company’s lime and limestone operations increased $9,242,000, or 42.8%, in the second quarter 2006 compared to the comparable 2005 quarter, including $4,275,000 of revenues from the Company’s St. Clair (Oklahoma) operations acquired at the end of 2005. For the six months ended June 30, 2006, revenues increased to $60,231,000 from $41,354,000 for the comparable period 2006, an increase of $18,877,000, or 45.6%. Revenues from the Company’s lime and limestone operations increased $17,189,000, or 41.6%, including $9,060,000 of revenues from the St. Clair operations. Revenues from the Company’s natural gas interests totaled $1,110,000 and $1,688,000 in the second quarter and first half 2006, respectively.

The Company reported net income of $4,343,000 ($0.69 per share diluted) in the second quarter 2006 compared to net income of $2,909,000 ($0.49 per share diluted) in the second quarter 2005, an increase of $1,434,000, or 49.3%. For the first six months 2006, the Company’s net income before cumulative effect of change in accounting principle increased to $7,190,000 ($1.15 per share diluted), compared to net income of $4,404,000 ($0.74 per share diluted) during the comparable 2005 period, an increase of $2,786,000, or 63.3%. Net income for the first half 2006 included a reduction of $550,000 ($0.09 per share diluted) for the cumulative effect of change in accounting principle, reflecting the write off of deferred stripping costs ($740,000, less $190,000 income tax benefit), as now required by EITF Issue No. 04-6. After giving effect for this change in accounting principle, the Company reported net income of $6,640,000 ($1.06 per share diluted) for the six months ended June 30, 2006, compared to net income of $4,404,000 ($0.74 per share diluted) for the first half 2005, an increase of $2,236,000, or 50.8%. The Company recognized stock-based compensation expense related to stock options in accordance with SFAS 123(R) of $172,000 ($130,000, or $0.02 per share diluted, net of income tax benefit) in the second quarter 2006 and $217,000 ($175,000, $0.03 per share diluted, net of income tax benefit) in the first half 2006.

The Company’s gross profit was $8,401,000 for the second quarter 2006, compared to $5,764,000 for the comparable 2005 quarter, an increase of $2,637,000, or 45.7%. For the first half 2006, gross profit was $14,797,000 compared to $10,153,000 for the comparable 2005 period, an increase of $4,644,000, or 45.7%. Included in gross profit for the 2006 second quarter and first half were $830,000 and $1,332,000, respectively, from the Company’s natural gas interests and $347,000 and $938,000, respectively, from the St. Clair operations. The increases in revenues and gross profit from lime and limestone operations were primarily due to average price increases for the Company’s products of approximately 8.5% and 8.3% in the second quarter and first half 2006, respectively, compared to the comparable 2005 periods and increased sales volumes from the Company’s Arkansas plant, as well as the revenues and gross profit from the St. Clair operations.

“Lime demand from our steel customers remained strong during the second quarter and is continuing into the third quarter,” said Timothy W. Byrne, President and Chief Executive Officer. “Even with a decline of approximately $1.35 per MCF in average natural gas prices received during the second quarter compared to the first quarter, we are pleased to report that our natural gas production volumes more than doubled resulting in a 65% increase in gross profit from our natural gas interests compared to the first quarter 2006,” Mr. Byrne added. “The construction schedule for the third kiln in Arkansas has slipped slightly, primarily due to slow equipment delivery and a shortage of skilled labor to construct the kiln. We currently anticipate bringing it on line this fall.”

The Company’s natural gas interest revenues were from its 20% royalty and 20% working interests in four gas wells drilled pursuant to the Company’s oil and gas lease covering its Johnson County, Texas property, which is located in the Barnett Shale Formation. The fourth well began production in early June 2006. The

Company is participating in two additional wells with completion expected in the third quarter 2006. Under the lease agreement, the operator is required to continually develop the lease properties. The Company currently intends to participate in additional wells expected to be drilled during 2006 and thereafter, but cannot predict the number that will be drilled or their results.
