UNITED STATES LIME & MINERALS REPORTS SECOND QUARTER 2024

RESULTS AND DECLARES REGULAR QUARTERLY CASH DIVIDEND

Dallas, Texas, July 31, 2024 - United States Lime & Minerals, Inc. (NASDAQ: USLM) today reported second quarter 2024 results: The Company’s revenues in the second quarter 2024 were $76.5 million, compared to $74.0 million in the second quarter 2023, an increase of $2.6 million, or 3.5%. For the first six months 2024, the Company’s revenues were $148.2 million, compared to $140.8 million in the first six months 2023, an increase of $7.5 million, or 5.3%. Lime and limestone revenues were $76.3 million in the second quarter 2024, compared to $73.7 million in the second quarter 2023, an increase of $2.6 million, or 3.5%. For the first six months 2024, lime and limestone revenues were $147.7 million, compared to $140.2 million in the first six months 2023, an increase of $7.5 million, or 5.3%. The increase in revenues in the second quarter and first six months 2024, compared to the comparable 2023 periods, resulted from increases in average selling prices for the Company’s lime and limestone products, partially offset by decreased sales volumes. The decreases in sales volumes in the second quarter and first six months 2024, compared to the comparable 2023 periods, were principally due to decreased demand from the Company’s construction customers, partially offset by increased demand from its industrial and roof shingle customers.

The Company’s gross profit was $34.8 million in the second quarter 2024, compared to $27.1 million in the second quarter 2023, an increase of $7.7 million, or 28.3%. The Company’s gross profit was $65.4 million in the first six months 2024, compared to $51.1 million in the first six months 2023, an increase of $14.3 million, or 28.0%. The Company’s lime and limestone gross profit was $34.8 million in the second quarter 2024, compared to $27.1 million in the second quarter 2023, an increase of $7.7 million, or 28.4%. The Company’s lime and limestone gross profit in the first six months 2024 was $65.5 million, compared to $51.2 million in the first six months 2023, an increase of $14.3 million, or 28.0%. The increases in gross profit in the second quarter and first six months 2024, compared to the comparable 2023 periods, resulted primarily from the increased revenues discussed above.

Selling, general and administrative (“SG&A”) expenses were $4.9 million in the second quarter 2024, compared to $4.3 million in the second quarter 2023, an increase of $0.6 million, or 13.0%. SG&A expenses were $9.7 million in the first six months 2024, compared to $8.5 million in the first six months 2023, an increase of $1.3 million, or 14.9%. The increases in SG&A expenses in the 2024 periods were primarily due to increased personnel expenses, including stock-based compensation.

Other (income) expense, net was $2.8 million and $5.3 million in the second quarter and first six months 2024, compared to $1.8 million and $3.3 million in the second quarter and first six months 2023, reflecting increases of $1.0 million and $2.0 million, respectively. The increases in other (income) expense, net in the second quarter and first six months 2024 were primarily due to interest earned on higher average balances of cash and cash equivalents.

The Company reported net income of $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, compared to $19.7 million ($0.69 per share diluted) and $36.8 million ($1.29 per share diluted) in the second quarter and first six months 2023, reflecting increases of $6.3 million, or 32.2%, and $11.7 million, or 31.7%, respectively. Comparative period per-share amounts have been retroactively adjusted to reflect the Company’s July 12, 2024 5-for-1 stock split discussed below.

“In the second quarter 2024, we experienced reduced demand from our construction customers as heavier than usual rainfalls contributed to the delay of construction projects in the south-central United States,” said Timothy W. Byrne, President and Chief Executive Officer. “Looking ahead, we expect improved demand from our construction customers will come with improved weather conditions,” Mr. Byrne added.

Stock Split

On July 12, 2024, the Company effected a 5-for-1 split of its common stock in the form of a stock dividend of four additional shares of common stock for each share outstanding to shareholders of record at the close of business on June 21, 2024. All share and per share information throughout this News Release has been retroactively adjusted to reflect the stock split.

Dividend

The Company announced today that the Board of Directors has declared a regular quarterly cash dividend of $0.05 per share on the Company’s common stock. This dividend is payable on September 13, 2024 to shareholders of record at the close of business on August 23, 2024.
