UNITED STATES LIME & MINERALS REPORTS SECOND QUARTER 2016

RESULTS AND DECLARES REGULAR QUARTERLY CASH DIVIDEND

Dallas, Texas, July 28, 2016 - United States Lime & Minerals, Inc. (NASDAQ: USLM) today reported second quarter 2016 results:  Revenues in the second quarter 2016 were $32.9 million, compared to $32.5 million in the comparable prior year quarter, an increase of $0.4 million, or 1.3%.  Revenues from the Company’s lime and limestone operations in the second quarter 2016 increased $0.6 million, or 1.9%, to $32.4 million from $31.8 million in the comparable 2015 quarter, while revenues from its natural gas interests decreased $0.2 million, or 24.9%, to $0.5 million from $0.7 million in the comparable prior year quarter.  For the six months ended June 30, 2016, revenues were $66.5 million, compared to $62.5 million in the comparable 2015 period, an increase of $4.0 million, or 6.3%.  Revenues from the Company’s lime and limestone operations in the first six months 2016 increased $4.4 million, or 7.2%, to $65.5 million from $61.1 million in the comparable 2015 period, while revenues from its natural gas interests decreased $0.4 million, or 31.8%, to $0.9 million from $1.4 million in the comparable prior year period.

The increases in lime and limestone revenues in the second quarter and first six months 2016, as compared to last year’s comparable periods, resulted primarily from increased sales volumes of the Company’s lime and limestone products due to increased demand, principally from its construction customers, partially offset by reduced demand from its oil and gas services customers. In both the 2016 and 2015 second quarters, demand from the Company’s construction customers was adversely impacted due to numerous days of rainfall during each of the quarters.  Prices realized for the Company’s lime and limestone products in the second quarter 2016 were slightly lower compared to the second quarter 2015 and slightly higher in the first six months 2016 compared to the first six months 2015. 

Production volumes from the Company’s natural gas interests in the second quarter 2016 totaled 157 thousand MCF, sold at an average price of $3.21 per MCF, compared to 183 thousand MCF, sold at an average price of $3.66 per MCF, in the comparable 2015 quarter.  Production volumes in the first six months 2016 from natural gas interests totaled 318 thousand MCF, sold at an average price of $2.95 per MCF, compared to the first six months 2015 when 371 thousand MCF was produced and sold at an average price of $3.70 per MCF.  The Company’s 2016 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 $7.2 million in the second quarter 2016, compared to $7.0 million in the comparable 2015 quarter, an increase of $0.2 million, or 3.3%. Gross profit in the first six months 2016 was $15.1 million, an increase of $2.2 million, or 17.2%, from $12.9 million in the first six months 2015.

Included in gross profit in the second quarter and first six months 2016 were $7.2 million and $15.2 million, respectively, from the Company’s lime and limestone operations, compared to $6.8 million and $12.5 million, respectively, in the comparable 2015 periods.  The increased gross profit for the Company’s lime and limestone operations in the second quarter and first six months 2015 resulted primarily from the increased revenues discussed above and an increase in the rate at which non-cash depletion expense was recorded in the 2016 periods.    

Gross profit from the Company’s natural gas interests decreased to losses of $4 thousand and $0.1 million in the second quarter and first six months 2016, respectively, from profits of $0.2 million and $0.4 million, respectively, in the comparable 2015 periods.  The decreased gross profit for the Company’s natural gas interests resulted primarily from the decreased revenues discussed above.

Interest expense decreased $0.5 million and $0.8 million in the second quarter and first six months 2016, respectively, compared to the comparable 2015 periods.  The decreases in interest expense resulted from the Company’s

repayment of the $15.4 million then-outstanding balance of its term loans in May 2015 and the Company’s repurchase of the related interest rate hedges in the second quarter 2015. 

During the second quarter 2015, the Company also 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, that was previously included in accumulated other comprehensive loss.  As a result of the termination of the Corson Pension Plan, the Company will not have to make any future contributions to the Plan.

The Company reported net income of $3.7 million ($0.66 per share diluted) in the second quarter 2016, compared to net income of $2.6 million ($0.46 per share diluted) in the second quarter 2015, an increase of $1.1 million, or 44.1%.  In the first six months 2016, net income increased $2.8 million, or 57.5%, to $7.8 million ($1.39 per share diluted), compared to $4.9 million ($0.88 per share diluted) in the first six months 2015. 

 “We are pleased that the increased demand for our lime and limestone products from our construction customers that began in the last half of 2015 continued into the first half 2016, although demand and pricing from our other customers remain a challenge,” said Timothy W. Byrne, President and Chief Executive Officer.
