UNITED STATES LIME & MINERALS REPORTS FIRST QUARTER 2015 RESULTS AND DECLARES REGULAR QUARTERLY CASH DIVIDEND

Dallas, Texas, April 29, 2015 - United States Lime & Minerals, Inc. (NASDAQ: USLM) today reported first quarter 2015 results: Revenues in the first quarter 2015 decreased to $30.1 million from $36.7 million in the first quarter 2014, a decrease of $6.6 million, or 18.1%. Revenues from the Company's lime and limestone operations in the first quarter 2015 decreased $5.7 million, or 16.2%, to $29.4 million from $35.1 million in the comparable 2014 quarter, while revenues from its natural gas interests decreased $0.9 million, or 57.2%, to $0.7 million from $1.6 million in the comparable prior year quarter.
The decrease in lime and limestone revenues in the first quarter 2015, compared to the first quarter 2014, resulted from decreased sales volumes of the Company's lime and limestone products, primarily as a result of decreased demand principally from its construction, steel, oil and gas services and industrial customers, partially offset by a slight increase in prices realized for its lime and limestone products in the 2015 quarter, compared to the 2014 quarter. The decreased demand from the Company's construction customers in the first quarter 2015, compared to the first quarter 2014, was primarily due to inclement weather conditions, compared to the favorable weather conditions experienced in first quarter 2014, as well as the increased construction demand in the first quarter 2014 that had resulted from the postponement of certain construction projects from the fourth quarter
2013 to the first quarter 2014. The decreased demand from the Company's steel customers in the first quarter
2015 was due to decreased steel production, while the decreased demand in the period from its oil and gas services customers was due to the ongoing reduced drilling activities resulting from the recent declines in oil and gas
prices.
Production volumes from the Company's natural gas interests in the first quarter 2015 totaled 187 thousand
MCF, sold at an average price of $3.75 per MCF, compared to 218 thousand MCF, sold at an average price of
$7.52 per MCF, in the comparable 2014 quarter. The Company's average price per MCF in the first quarter 2015 was lower than its average price in the first quarter 2014 primarily due to decreases in natural gas prices.
The Company's gross profit was $5.9 million in the first quarter 2015, compared to $8.6 million in the first quarter 2014, a decrease of $2.7 million, or 31.5%. Included in gross profit for the 2015 quarter was $5.7 million from the Company's lime and limestone operations, compared to $7.7 million in the comparable 2014 quarter. The decreased gross profit for the Company's lime and limestone operations in the first quarter 2015, compared to the first quarter 2014, resulted primarily from the decreased revenues discussed above. Gross profit from the Company's natural gas interests decreased to $0.2 million in the first quarter 2015, from $0.9 million in the comparable 2014 quarter, primarily due to the decrease in revenues discussed above.
The Company reported net income of $2.4 million ($0.42 per share diluted) in the first quarter 2015, compared to net income of $4.5 million ($0.80 per share diluted) in the first quarter 2014, a decrease of $2.1 million, or 47.4%.
'We had unusually persistent adverse weather in the 2015 quarter, including ice and snow storms and rain, compared to the first quarter 2014,' said Timothy W. Byrne, President and Chief Executive Officer. 'Although we expect demand from our construction customers to return to more normal levels for the remainder of 2015, we also expect demand from our steel and oil and gas services customers to continue to be lower than last year's levels,' Mr. Byrne added.
