UNITED STATES LIME & MINERALS REPORTS FIRST QUARTER 2026

RESULTS AND DECLARES REGULAR QUARTERLY CASH DIVIDEND

Dallas, Texas, April 29, 2026 - United States Lime & Minerals, Inc. (NASDAQ: USLM) today reported first quarter 2026 results: The Company’s revenues in the first quarter 2026 were $87.8 million, compared to $91.3 million in the first quarter 2025, a decrease of $3.4 million, or 3.7%. The decrease in revenues in the first quarter 2026, compared to the first quarter 2025, resulted primarily from decreased sales volumes, principally due to decreased demand from the Company’s construction, oil and gas services, and roof shingle customers, partially offset by increased demand from the Company’s steel customers. During the first quarter 2026, the Company caught up on most of the weather-related shipping interruptions that resulted from the January winter storm.

The Company’s gross profit was $41.8 million in the first quarter 2026, compared to $46.2 million in the first quarter 2025, a decrease of $4.4 million, or 9.5%. The decrease in gross profit in the first quarter 2026, compared to the first quarter 2025, resulted primarily from the decrease in revenues discussed above and higher fuel and transportation costs.

Selling, general and administrative (“SG&A”) expenses were $6.0 million in the first quarter 2026, compared to $6.3 million in the first quarter 2025, a decrease of $0.3 million, or 4.7%. The decrease in SG&A expenses in the first quarter 2026, compared to the first quarter 2025, was primarily due to decreased personnel expenses, including stock-based compensation.

Other (income) expense, net was $3.2 million income in the first quarter 2026, compared to $3.1 million income in the first quarter 2025, an increase of $0.1 million, primarily due to interest earned on higher average balances of cash and cash equivalents.

The Company reported net income of $30.6 million ($1.06 per share diluted) in the first quarter 2026, compared to $34.1 million ($1.19 per share diluted) in the first quarter 2025, a decrease of $3.5 million, or 10.4%.

“Although we experienced our first revenue decrease against the comparable prior-year quarter since the COVID pandemic began in 2020, we remain optimistic about the balance of the year, including as it pertains to demand from our construction customers,” said Timothy W. Byrne, President and Chief Executive Officer. “We are also pleased with the progress on the new kiln project at our Texas facility and anticipate it will start up this summer,” Mr. Byrne added.

Dividend

The Company announced today that the Board of Directors has declared a regular quarterly cash dividend of $0.06 per share on the Company’s common stock. This dividend is payable on June 12, 2026 to shareholders of record at the close of business on May 22, 2026.
