UNITED STATES LIME & MINERALS REPORTS SECOND QUARTER 2025

RESULTS AND DECLARES REGULAR QUARTERLY CASH DIVIDEND

Dallas, Texas, July 30, 2025 - United States Lime & Minerals, Inc. (NASDAQ: USLM) today reported second quarter 2025 results: The Company’s revenues in the second quarter 2025 were $91.5 million, compared to $76.5 million in the second quarter 2024, an increase of $15.0 million, or 19.6%. For the first six months 2025, the Company’s revenues were $182.8 million, compared to $148.2 million in the first six months 2024, an increase of $34.5 million, or 23.3%. The increases in revenues in the second quarter and first six months 2025, compared to the comparable 2024 periods, resulted from increases in sales volumes of the Company’s lime and limestone products, principally to the Company’s construction, environmental, and steel customers, and increases in average selling prices for the Company’s lime and limestone products.

The Company’s gross profit was $41.9 million in the second quarter 2025, compared to $34.8 million in the second quarter 2024, an increase of $7.1 million, or 20.3%. The Company’s gross profit in the first six months 2025 was $88.0 million, compared to $65.4 million in the first six months 2024, an increase of $22.6 million, or 34.5%. The increases in gross profit in the second quarter and first six months 2025, compared to the comparable 2024 periods, resulted primarily from the increases in revenues discussed above.

Selling, general and administrative (“SG&A”) expenses were $6.2 million in the second quarter 2025, compared to $4.9 million in the second quarter 2024, an increase of $1.3 million, or 26.8%. SG&A expenses were $12.5 million in the first six months 2025, compared to $9.7 million in the first six months 2024, an increase of $2.7, million or 28.0%. The increases in SG&A expenses in the second quarter and first six months 2025, compared to the comparable 2024 periods, were primarily due to increased personnel expenses, including stock-based compensation.

Other (income) expense, net was $3.1 million and $6.2 million income in the second quarter and first six months 2025, compared to $2.8 million and $5.3 million income in the second quarter and first six months 2024, reflecting increases of $0.3 million and $0.9 million, respectively. The increases in other (income) expense, net for the second quarter and first six months 2025, compared to the comparable 2024 periods, were primarily due to interest earned on higher average balances of cash and cash equivalents.

The Company reported net income of $30.8 million ($1.07 per share diluted) and $64.9 million ($2.26 per share diluted) in the second quarter and first six months 2025, compared to $26.1 million ($0.91 per share diluted) and $48.5 million ($1.69 per share diluted) in the second quarter and first six months 2024, reflecting increases of $4.8 million, or 18.3%, and $16.4 million, or 33.9%, respectively.

“We are pleased with the Company’s strong financial performance in the second quarter 2025. Demand from our construction customers remained solid,” said Timothy W. Byrne, President and Chief Executive Officer.
