SECOND-QUARTER 2026 RESULTS

Net sales for the quarter were $613.9 million, compared to $431.7 million in the prior year period. Value-added sales were $308.2 million for the quarter, up 15% from the prior year period driven by the highest quarterly aerospace & defense sales with significant growth seen across semiconductor, industrial, energy and telecom & data center end markets.

Operating profit for the quarter was $51.7 million and net income was $38.8 million, or $1.84 per diluted share, compared to operating profit of $36.8 million and net income of $25.1 million, or $1.21 per share, in the prior year period.

Excluding special items4, adjusted EBITDA was at an all-time quarterly high of $71.8 million, a quarterly record of 23.3% of value-added sales, compared to $55.8 million or 20.8% of value-added sales in the prior year period. The record adjusted EBITDA and margin was driven by higher volume, strong price/mix and operational performance, as well as some favorable one-time items.

Adjusted net income was $40.1 million excluding acquisition amortization, or $1.90 per diluted share, compared to $1.37 per share in the prior year period.

OUTLOOK

Our first half results combined with increasing backlog and strong order rate momentum improves our confidence in delivering record full-year results. We now expect mid-teens top-line growth and are raising our full-year adjusted earnings per share guidance to $6.80 to $7.20, a 30% increase from prior year at the midpoint.

ADJUSTED EARNINGS GUIDANCE

It is not possible for the Company to identify the amount or significance of future adjustments associated with potential insurance and litigation claims, legacy environmental costs, acquisition and integration costs, certain income tax items, or other non-routine costs that the Company adjusts in the presentation of adjusted earnings guidance. These items are dependent on future events that are not reasonably estimable at this time. Accordingly, the Company is unable to reconcile without unreasonable effort the forecasted range of adjusted earnings guidance for the full year to a comparable GAAP range. However, items excluded from the Company's adjusted earnings guidance include the historical adjustments noted in Attachments 4 through 8 to this press release.
