UNITED STATES LIME & MINERALS DECLARES QUARTERLY CASH DIVIDEND

AND REPORTS FOURTH QUARTER AND FULL-YEAR 2013 RESULTS

Dallas, Texas, January 29, 2014 - United States Lime & Minerals, Inc. (NASDAQ: USLM) today reported fourth quarter and full-year 2013 results:  Revenues in the fourth quarter 2013 decreased to $30.1 million from $31.9 million in the fourth quarter 2012, a decrease of $1.8 million, or 5.6%.  Revenues from the Company’s lime and limestone operations in the fourth quarter 2013 decreased $1.5 million, or 5.1%, to $28.7 million from $30.2 million in the comparable 2012 quarter, while revenues from its natural gas interests decreased $0.2 million, or 13.6%, to $1.4 million from $1.7 million in the comparable prior year quarter.  For full-year 2013, revenues decreased to $133.8 million from $138.5 million in 2012, a decrease of $4.8 million, or 3.4%.  Revenues from the Company’s lime and limestone operations for full-year 2013 decreased $3.4 million, or 2.6%, to $128.0 million from $131.4 million in 2012, while revenues from its natural gas interests decreased $1.4 million, or 19.1%, to $5.8 million from $7.1 million in the prior year.

The decrease in lime and limestone revenues in the fourth quarter 2013 as compared to the fourth quarter 2012 resulted primarily from decreased sales volumes of the Company’s lime and limestone products as a result of decreased demand from its construction customers due to inclement weather conditions in the 2013 quarter compared to favorable weather conditions in the comparable 2012 quarter. The decrease in lime and limestone revenues in full-year 2013, compared to 2012, resulted primarily from decreased demand, principally  from the Company’s steel customers, partially offset by increased sales volumes to the Company’s construction and environmental customers and a slight increase in prices realized for the Company’s lime and limestone products in 2013, compared to 2012.

Production volumes from the Company’s natural gas interests for the fourth quarter 2013 totaled 233 thousand MCF, sold at an average price of $6.20 per MCF, compared to 284 thousand MCF, sold at an average price of $5.89 per MCF, in the comparable 2012 quarter.  Production volumes for full-year 2013 from natural gas interests totaled 983 thousand MCF, sold at an average price of $5.86 per MCF, compared to 2012 when 1.2 BCF was produced and sold at an average price of $5.74 per MCF.  The Company’s average prices per MCF exceeds average natural gas prices because the Company’s natural gas contains liquids.  The Company’s average prices per MCF in the 2013 periods were higher than its prices in the prior year’s comparable periods due to the increases in natural gas prices, partially offset by lower prices for natural gas liquids.

The Company’s gross profit was $6.4 million in the fourth quarter 2013, compared to $8.1 million in the comparable 2012 quarter, a decrease of $1.7 million, or 20.8%. For full-year 2013, gross profit was $30.8 million, a decrease of $2.6 million, or 7.9%, from $33.4 million in 2012.

Included in gross profit for the fourth quarter and full-year 2013 were $5.5 million and $27.9 million, respectively, from the Company’s lime and limestone operations, compared to $7.3 million and $29.5 million, respectively, in the comparable 2012 periods.  The decreased gross profit for the Company’s lime and limestone operations in the 2013 periods resulted primarily from the decreased sales volumes and revenues discussed above and increased costs of revenues due to production inefficiencies, resulting from the inclement weather conditions.

Gross profit from the Company’s natural gas interests increased to $1.0 million for the fourth quarter, from $0.9 million, in the comparable 2012 quarter, primarily due to a reduction in depletion expense in the fourth quarter 2013 because of an increase in the Company’s natural gas reserves as of December 31, 2013 resulting from the increase in the average natural gas price for 2013, compared to the average natural gas price for 2012.  This was partially offset by the decrease in revenues in the 2013 quarter discussed above.  The decrease in gross profit for the full-year 2013 from the Company’s natural gas interests resulted from the

decrease in revenues discussed above.  No new wells were drilled in 2013 or are currently being drilled.  The Company cannot predict the number of additional wells that ultimately will be drilled, if any, or their results.

The Company reported net income of $2.6 million ($0.47 per share diluted) in the fourth quarter 2013, compared to net income of $3.8 million ($0.68 per share diluted) in the fourth quarter 2012, a decrease of $1.2 million, or 30.7%.  For full-year 2013, the Company’s net income decreased by $1.6 million, or 9.9%, to $14.8 million ($2.66 per share diluted), from $16.4 million ($2.87 per share diluted) in 2012.

The Company also announced today that the Board of Directors has declared a quarterly cash dividend of $0.125 (12.5 cents) per share on the Corporation’s common stock. This dividend, which represents a cash dividend of $0.50 (50 cents) per share on an annualized basis, is payable March 20, 2014, to shareholders of record at the close of business on February 28, 2014.

“Inclement weather in the fourth quarter 2013 resulted in a significant decline in construction demand for our lime and limestone products,” said Timothy W. Byrne, President and Chief Executive Officer. “However, we believe this demand was merely postponed until 2014 as our customers’ projects are still underway.”  Mr. Byrne added, “We are pleased that we continue to generate significant cash flows from our operations and that our balance sheet remains strong, enabling us to pay quarterly dividend distributions to our shareholders.”
