And this quarter, we strengthened our position even further. We secured a new $15 million program to deliver advanced materials critical to engine performance for a major commercial space customer. This is a meaningful win and a clear signal of the trust customers place in Materion to support their most demanding missions. Q2 was an exceptional quarter. I'm incredibly proud of what our people have accomplished. Their commitment and hard work were evident across the board and were instrumental in delivering our outstanding results. I'm excited about the trajectory that we're on and look forward to what's next. With that, I'll turn the call over to Shelly to walk through the financial details.
Thanks, Dougal, and good morning, everyone. During my comments, I will reference the slides posted on our website this morning, starting on slide 11. In the second quarter, value-added sales, which exclude the impact of pass-through precious metal costs, were a record $308.2 million, up 15% from the prior year and up 18% sequentially. This year-over-year increase was driven by our highest quarterly aerospace and defense sales and significant growth seen across semiconductor, industrial, energy, and telecom and data center. Additionally, as Jewel mentioned, all three of our businesses delivered double-digit year-over-year sales growth, highlighting the strong performance seen across the company. Adjusted earnings per share were a record $1.90, up 39% from the prior year, and up 50% sequentially. Turning to slide 12, adjusted EBITDA was a record $71.8 million, or 23.3% of value-added sales, an increase of 29% year-over-year with 250 basis points of margin expansion. This increase was driven by higher volume and favorable price mix and strong operational performance, along with the benefit of some one-time items. Moving to slide 13, let me review second quarter results by business segment. Starting with performance materials, value-added sales are $190 million in the quarter, up 13% year-over-year and up 36% sequentially. This year-over-year increase was driven by significant growth across the aerospace and defense, telecom and data center, energy and semiconductor and markets. In addition to market strength, the strong sequential increase was driven by new business initiatives and the return to a normalized level of clad strip sales. adjusted EBITDA was 48.3 million or 25.4 percent of value-added sales up 16 percent compared to the prior year period with 80 basis points of margin expansion this increase was driven by higher volume and strong price mix sequentially adjusted EBITDA was up 70 percent with 500 basis points of margin expansion looking out at the second half of 2026 we expect continued top-line momentum supported by accelerating order book activity across most of our end markets, led by space, defense, and semiconductor. Turning to slide 14, electronic materials delivered another exceptional quarter. Value-added sales were $87.4 million, up 15% year-over-year, driven by continued strength in semiconductor, as AI adoption fuels high demand for semiconductor chips and data storage devices, complemented by the benefit of new business wins. We delivered a record-adjusted EBITDA of $28 million, or 32% of value-added sales, up 57% year-over-year, with nearly 900 basis points of margin expansion. This marks the fifth consecutive quarter of expanded margins in EM. These outstanding results reflect the higher volume, favorable price mix, and strong operational performance, along with the impact of new business and benefits from the cost optimization work done over the last few years. For the remainder of 2026, we expect to see additional top-line improvement driven by increasing demand from the semiconductor market and continued contributions from new business.
