Albany International Reports Second-Quarter 2025 Results

ROCHESTER, N.H.--(BUSINESS WIRE)--July 30, 2025 — Albany International Corp. (NYSE:AIN) today reported operating results for its second quarter of 2025, which ended June 30, 2025.

"Overall, I am encouraged with our progress this year. Our business segment leaders are performing well as they restructure, invest and strengthen their operations. Our second quarter financial results lagged our expectations, but the performance was largely impacted by certain timing and operational issues and we are confident in our recovery," said President and CEO, Gunnar Kleveland.

"In Machine Clothing, despite some second quarter timing and market headwinds, the business delivered expected returns on the lower volume and showed growth from the first quarter. AEC delivered strong sequential quarter growth and continues to accelerate its disciplined long-term operational strategy" concluded Kleveland.

For the second quarter ended June 30, 2025: •Net revenues were $311 million, down 6.2%, or 7.4% after adjusting for currency translation, when compared to the prior year. MC's net revenues decreased 6.5%, which was primarily driven by reduced demand in Asia and unplanned equipment downtime in one of our production facilities. AEC's net revenues decreased 5.7%, primarily driven by reductions on certain commercial and space programs, which was partially offset by higher revenues on CH-53K and other programs. •Gross profit of $98 million was 13.2% lower than the $112 million reported for the same period of 2024; overall gross margin decreased 260 basis points primarily due to changes in the estimated profitability of long-term contracts at AEC. •Selling, General, and Administrative (SG&A) expenses were $59 million, slightly higher than prior yea
