UNITED STATES LIME & MINERALS DECLARES REGULAR QUARTERLY

CASH DIVIDEND AND REPORTS THIRD QUARTER 2014 RESULTS

Dallas, Texas, October 29, 2014 - United States Lime & Minerals, Inc. (NASDAQ: USLM) today reported third quarter 2014 results:  Revenues increased to $39.1 million from $36.9 million in the comparable 2013 quarter, an increase of $2.2 million, or 5.9%.  Revenues from the Company’s lime and limestone operations in the third quarter 2014 increased $2.4 million, or 6.6%, to $37.9 million from $35.5 million in the comparable 2013 quarter, while revenues from its natural gas interests decreased $0.2 million, or 13.1%, to $1.2 million from $1.4 million in the comparable prior year quarter.  For the nine months ended September 30, 2014, revenues increased to $114.4 million from $103.7 million in the comparable 2013 period, an increase of $10.8 million, or 10.4%.  Revenues from the Company’s lime and limestone operations in the first nine months 2014 increased $10.9 million, or 11.0%, to $110.2 million from $99.3 million in the comparable 2013 period, while revenues from its natural gas interests decreased $0.1 million, or 2.4%, to $4.2 million from $4.3 million in the comparable prior year period.

The increase in lime and limestone revenues in the 2014 periods, compared to the comparable 2013 periods, resulted from increased sales volumes to the Company’s construction, oil and gas services and industrial customers, compared to the comparable 2013 periods.  In addition, in the first nine months 2014, a portion of the increase in lime and limestone sales volumes resulted from lime sales to another lime producer for delivery to its customers, which sales primarily occurred in the second quarter 2014 and ceased in August 2014.  Also, prices realized for the Company’s lime and limestone products in the 2014 periods increased slightly, compared to the comparable 2013 periods.

Production volumes from the Company’s natural gas interests in the third quarter 2014 totaled 209 thousand MCF, sold at an average price of $5.84 per MCF, compared to 239 thousand MCF, sold at an average price of $5.87 per MCF, in the comparable 2013 quarter.  Production volumes in the first nine months 2014 from natural gas interests totaled 641 thousand MCF, sold at an average price of $6.57 per MCF, compared to the first nine months 2013 when 751 thousand MCF was produced and sold at an average price of $5.75 per MCF.  The Company’s average price per MCF for the first nine months 2014 was higher than the average price for the comparable 2013 period primarily due to increases in natural gas prices in the first six months 2014.

The Company’s gross profit was $9.9 million in the third quarter 2014, compared to $9.1 million in the comparable 2013 quarter, an increase of $0.8 million, or 8.5%. Gross profit in the first nine months 2014 was $28.9 million, an increase of $4.5 million, or 18.6%, from $24.4 million in the first nine months 2013.

Included in gross profit in the third quarter and first nine months 2014 were $9.3 million and $26.6 million, respectively, from the Company’s lime and limestone operations, compared to $8.4 million and $22.4 million, respectively, in the comparable 2013 periods.  The increased gross profit for the Company’s lime and limestone operations in the third quarter and first nine months 2014 resulted primarily from the increased revenues discussed above.

Gross profit from the Company’s natural gas interests was $0.6 million and $2.3 million in the third quarter and first nine months 2014, respectively, compared to $0.7 million and $1.9 million, respectively, in the comparable 2013 periods.

The Company reported net income of $5.4 million ($0.97 per share diluted) in the third quarter 2014, compared to net income of $4.8 million ($0.86 per share diluted) in the third quarter 2013, an increase of $0.6 million, or 13.3%.  In the first nine months 2014, net income increased by $3.5 million, or 28.5%, to $15.6 million ($2.80 per share diluted), compared to $12.2 million ($2.19 per share diluted) in the first nine months 2013.

“We are pleased that increased sales volumes for our lime and limestone products resulted in increased revenues in this year’s third quarter, compared to the third quarter 2013,” said Timothy W. Byrne, President and Chief Executive Officer.  “However, we remain concerned about the consistent availability of truck transportation to deliver our products to our customers on a timely basis,” Mr. Byrne added.

Dividend

The Company also announced today that its Board of Directors has declared a regular quarterly cash dividend of $0.125 (12.5 cents) per share on the Company’s common stock. This dividend is payable on December 18, 2014 to shareholders of record at the close of business on November 28, 2014.
