manufacturing facility, which resulted in the recording of a one-time gain of $339,520. It also highlights the Company’s progress in managing cost pressures and stabilizing operations in a difficult environment. Looking ahead, we remain focused on improving profitability through a combination of targeted customer engagement, pricing strategies, and operational efficiencies. However, we recognize that industry headwinds including inflation, supply chain complexity, and changing customer demand patterns may continue to affect our near-term financial performance.
Fastener segment sales were $6,433,949 for the three months ended September 30, 2025 compared to $5,927,316 for the three months ended September 30, 2024, an increase of $506,633, or 8.5%. Fastener segment sales were $18,990,136 for the nine months ended September 30, 2025 compared to $19,560,720 for the nine months ended September 30, 2024, a decline of $570,584, or 2.9%. The automotive sector is the primary market for our fastener segment products, and sales to automotive customers were $4,228,502 for the three months ended September 30, 2025 compared to $3,578,390 for the three months ended September 30, 2024, an increase of $650,112, or 18.2%. Sales to automotive customers were $11,876,239 for the nine months ended September 30, 2025 compared to $13,050,096 for the nine months ended September 30, 2024, a decline of $1,173,857, or 9.0% primarily due to a slowdown in North American vehicle production and continued volatility across the Midwest automotive manufacturing sector. Industry-wide production fell sharply in January 2025, leading to reduced order volumes from key original equipment manufacturers. In addition, elevated interest rates and ongoing economic uncertainty contributed to softer consumer demand, prompting inventory adjustments and cautious procurement behavior among our automotive customers. In contrast, fastener segment sales to non-automotive customers, including those in the construction and electronics industries, were $2,205,447 for the three months ended September 30, 2025 compared to $2,348,926 for the three months ended September 30, 2024, a decrease of $143,479, or 6.1%, and $7,113,897 for the nine months ended September 30, 2025 compared to $6,510,624 for the nine months ended September 30, 2024, an increase of $603,273, or 9.3%, reflecting the successful execution of a strategic pivot by our sales team. In response to softening demand in the automotive sector, the sales team proactively expanded outreach to customers in industrial, construction, and consumer goods markets, which are segments that have historically demonstrated more stable demand profiles amid broader economic headwinds.
Assembly equipment segment sales were $926,335 for the three months ended September 30, 2025 compared to $1,042,605 for the three months ended September 30, 2024, a decrease of $116,270, or 11.2%. Assembly equipment segment sales were $2,913,861 for the nine months ended September 30, 2025 compared to $3,321,859 for the nine months ended September 30, 2024, a decrease of $407,998, or 12.3%. Both automotive and non-automotive assembly equipment sales decreased in this segment. These declines reflect timing-related factors in customer purchasing cycles as well as project delays stemming from cautious capital investment trends across multiple industries. Although sales declined year-over-year, the assembly equipment gross margin increased by $715,056 during the year-to-date period. This margin expansion reflects the Company’s ongoing efforts to enhance operational efficiency and reduce its cost structure, with the consolidation of the Albia operations into the Tyrone manufacturing facility yielding meaningful cost savings through streamlined workflows, increased capacity utilization, and reduced overhead.

The decrease was primarily attributable to lower interest income earned on short-term investments, which declined due to a reduction in the average balance of such investments during the current period. Other income for the nine months ended September 30, 2025 was $356,302 compared to $102,570 for the nine months ended September 30, 2024, an increase of $253,732 primarily driven by the sale of the Albia manufacturing facility which resulted in the recording of a one-time gain of $339,520.
