ACME UNITED REPORTS

FIRST QUARTER 2026 FINANCIAL RESULTS

SHELTON, CT – April 23, 2026 – Acme United Corporation (NYSE American: ACU) today announced that net sales for the quarter ended March 31, 2026 were $52.3 million compared to $46.0 million for the quarter ended March 31, 2025, an increase of 14%. Excluding incremental sales resulting from the acquisition of the assets of My Medic on January 15, 2026, comparable sales increased 6%.

Net income was $1.0 million, or $0.24 per diluted share, for the quarter ended March 31, 2026, compared to $1.7 million, or $0.41 per diluted share, for the comparable period last year, a decrease of 40% in net income and 41% in diluted earnings per share. This decrease was due to higher cost of sales and increased operating expenses primarily as a result of higher tariff-related costs and investments in enhanced quality assurance protocols at the Med-Nap facility, together with rising employee healthcare expenses. Tariff expenses were recognized during the first quarter as the company sold inventory that had been subject to higher tariff rates imposed in 2025.

The recently acquired My Medic business, which sells tactical, trauma and emergency response products directly to consumers, contributed to sales growth, with minimal impact on earnings in the first quarter. As a direct-to-consumer seasonal business, My Medic is expected to generate the majority of its profitability in the fourth quarter.

Chairman and CEO, Walter C. Johnsen said, “While we experienced higher costs of sales and operating expenses in the first quarter, the impact was magnified due to the seasonality of our business, which traditionally has lower sales in the first quarter. We are actively working to improve profitability. We just moved into our new Spill Magic facility in Tennessee- in the process lowering expenses and providing room to expand;

consolidated one of our sites in Canada; and are continuing to install automation throughout our facilities. My Medic, which has annual sales of $19 million, offers many compelling growth and cost saving opportunities. We are expanding My Medic’s retail distribution while also leveraging Acme United’s strong purchasing network to reduce costs, cutting overhead, and consolidating functions. Importantly, the expenses incurred for the enhanced quality assurance protocols at the Med-Nap facility were one-time, non-recurring expenses.”

Mr. Johnsen continued, “We have been proactively purchasing additional inventory in preparation for product shortages and cost increases resulting from the conflict in Iran. To date, we have added approximately $10 million of incremental orders for delivery in the second and third quarters and are carefully evaluating additional purchases.”

Mr. Johnsen concluded, “Acme United has extensive experience with supply chain challenges, and I am confident that our team will address them successfully. I also believe the investments we have been making in expanding Acme United’s business lines, technology, and capacity will continue to strengthen our Company.”

For the first quarter of 2026, net sales in the U.S. segment increased 12% compared to the same period in 2025 due to increased sales of first aid and medical products and additional sales resulting from the acquisition of My Medic.

European net sales for the first quarter of 2026 increased 32% in U.S. dollars and 19% in local currency compared to the first quarter of 2025 due primarily to higher ecommerce sales and additional sales resulting from the acquisition of the line of cutting and sharpening products in Germany on October 1, 2025.

Net sales in Canada for the first quarter of 2026 increased 16% in U.S. dollars and 11% in local currency compared to the same period in 2025 due to higher sales of first aid products.

Gross margin was 39.7% in the first quarter of 2026 versus 39.0% in the comparable period last year.

The Company’s bank debt less cash as of March 31, 2026 was $38.6 million compared to $27.2 million as of March 31, 2025. During the twelve-month period ended March 31, 2026, the Company paid approximately $14.6 million for the acquisition of the assets of My Medic ($18.7 million purchase price less $4.1 million of holdbacks), distributed approximately $2.4 million in dividends on its common stock and purchased the cutting and sharpening line of products in Germany for approximately $1.6 million. Additionally, the Company generated approximately $14.2 million in free cash flow, before the purchase for cash of a new $6.0 million manufacturing and distribution facility in Tennessee in July 2025 to expand the Company’s Spill Magic business.
