UNITED STATES LIME & MINERALS REPORTS THIRD QUARTER 2015 RESULTS

AND DECLARES REGULAR QUARTERLY CASH DIVIDEND

Dallas, Texas, October 28, 2015 - United States Lime & Minerals, Inc. (NASDAQ: USLM) today reported third quarter 2015 results:  Revenues in the third quarter 2015 were $37.0 million, compared to $39.1 million in the comparable prior year quarter, a decrease of $2.0 million, or 5.2%.  Revenues from the Company’s lime and limestone operations in the third quarter 2015 decreased $1.4 million, or 3.7%, to $36.5 million from $37.9 million in the comparable 2014 quarter, while revenues from its natural gas interests decreased $0.6 million, or 52.6%, to $0.6 million from $1.2 million in the comparable prior year quarter.  For the nine months ended September 30, 2015, revenues were $99.5 million, compared to $114.4 million in the comparable 2014 period, a decrease of $14.9 million, or 13.0%.  Revenues from the Company’s lime and limestone operations in the first nine months 2015 decreased $12.6 million, or 11.5%, to $97.6 million from $110.2 million in the comparable 2014 period, while revenues from its natural gas interests decreased $2.3 million, or 53.7%, to $2.0 million from $4.2 million in the comparable prior year period.

The decrease in lime and limestone revenues in the third quarter 2015, compared to the third quarter 2014, resulted primarily from decreased sales volumes of the Company’s lime and limestone products due to decreased demand, principally from its oil and gas services and steel customers due to decreased drilling activities and decreased steel production, respectively, partially offset by increased demand from its construction customers.  The decrease in lime and limestone revenues in the nine months ended September 30, 2015, compared to the comparable 2014 period, resulted primarily from decreased demand from the Company’s oil and gas services, steel, industrial and construction customers.  Prices realized for the Company’s lime and limestone products in the 2015 periods were slightly higher compared to the 2014 periods.

Production volumes from the Company’s natural gas interests in the third quarter 2015 totaled 177 thousand MCF, sold at an average price of $3.25 per MCF, compared to 209 thousand MCF, sold at an average price of $5.84 per MCF, in the comparable 2014 quarter.  Production volumes in the first nine months 2015 from natural gas interests totaled 548 thousand MCF, sold at an average price of $3.56 per MCF, compared to the first nine months 2014 when 641 thousand MCF was produced and sold at an average price of $6.57 per MCF.  The Company’s 2015 average prices per MCF were lower than the prior year’s average prices primarily due to decreases in natural gas and natural gas liquids prices.

The Company’s gross profit was $10.4 million in the third quarter 2015, compared to $9.9 million in the comparable 2014 quarter, an increase of $0.5 million, or 4.9%. Gross profit in the first nine months 2015 was $23.2 million, a decrease of $5.7 million, or 19.6%, from $28.9 million in the first nine months 2014.

Included in gross profit in the third quarter and first nine months 2015 were $10.3 million and $22.8 million, respectively, from the Company’s lime and limestone operations, compared to $9.3 million and $26.6 million, respectively, in the comparable 2014 periods.  The increased gross profit in the third quarter 2015, compared to the third quarter 2014, resulted primarily from lower energy costs as well as less discretionary outside contractor stripping costs in the Company’s quarries, partially offset by the decreased revenues discussed above.  The decreased gross profit for the Company’s lime and limestone operations in the first nine months 2015 resulted primarily from the decreased revenues discussed above.

Gross profit from the Company’s natural gas interests decreased to $47 thousand and $0.4 million in the third quarter and first nine months 2015, respectively, from $0.6 million and $2.3 million, respectively, in the comparable 2014 periods.  The decreased gross profit for the Company’s natural gas interests resulted primarily from the decreased revenues discussed above.

Interest expense in the third quarter 2015 decreased $0.3 million, compared to the third quarter 2014, primarily as a result of the company’s repayment of the $15.4 million then-outstanding balance of its term loans in the second quarter 2015.  Interest expense decreased $0.2 million in the first nine months 2015 compared to the first nine months 2014 primarily as a result of the repayment of debt, partially offset by the cost to repurchase of the Company’s interest rate hedges in the second quarter 2015.

During the second quarter 2015, the Company terminated the Corson Pension Plan, which required a cash payment of $0.2 million and resulted in a second quarter expense of $0.9 million ($0.6 million, net of tax benefit), included in other (income) expense, net for the first nine months 2015, that was previously included in accumulated other comprehensive loss.  As a result of the termination of the Corson Plan, the Company will not have to make any future contributions to the Plan.

The Company reported net income of $5.7 million ($1.01 per share diluted) in the third quarter 2015, compared to net income of $5.4 million ($0.97 per share diluted) in the third quarter 2014, an increase of $0.3 million, or 4.6%.  In the first nine months 2015, net income decreased by $5.0 million, or 32.2%, to $10.6 million ($1.89 per share diluted), compared to $15.6 million ($2.80 per share diluted) in the first nine months 2014.

“With the greatly improved weather conditions in the third quarter 2015 compared to the first two quarters, we were pleased to see demand from our construction customers rebound,” said Timothy W. Byrne, President and Chief Executive Officer.  “However, we continue to see reduced demand from our oil and gas services and steel customers compared to last year,” 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, 2015 to shareholders of record at the close of business on November 27, 2015.
