Check the appropriate box below if the Form 8-K is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions:

Carpenter Technology Corporation announced today that it will change its reportable segments, beginning with its fiscal second quarter results, to align with a new operating model in which its integrated steel mill operations will be managed distinctly from the collection of other differentiated business unit operations. Initially, there will be two reportable segments, Specialty Alloys Operations (“SAO”) and Performance Engineered Products (“PEP”). Once the Company completes its acquisition of Latrobe Specialty Metals, Latrobe will become a third reportable segment. Previously, the Company’s reportable segments consisted of Premium Alloys Operations (PAO), Advanced Metals Operations (AMO) and Emerging Ventures.

The SAO segment will be comprised of Carpenter’s major premium alloy and stainless steel manufacturing operations. This includes operations performed at mills primarily in Reading, Pennsylvania and the surrounding area, South Carolina, and the new premium products manufacturing facility being built in Limestone County, Alabama. The combined assets of the SAO operations will be managed in an integrated manner to optimize efficiency and profitability across the total system.

The PEP segment will be comprised of Carpenter’s differentiated operations. This includes the Dynamet titanium business, the Carpenter Powder Products (CPP) business, and the Amega West business. The businesses in the PEP segment will be managed with an entrepreneurial structure to promote speed and flexibility, and drive overall revenue and profit growth.

The Latrobe segment, effective upon closing the acquisition, will provide initial management focus on successfully integrating the business into Carpenter, and visibility into the business performance of this operation. As this business becomes integrated with Carpenter, its results will likely be reported within the SAO business segment sometime in the future.

In conjunction with the segment reporting changes, Carpenter will also make a few modifications to its supplemental end-use market and product class reporting.

For end-use market reporting, Aerospace end-use market sales will be broadened to incorporate Aerospace and Defense. Industrial and Consumer end-use market sales will be combined as Industrial and Consumer. The Automotive end-use market will be broadened to Transportation to reflect sales in non-automotive markets like marine. All distribution businesses sales will be reported as a separate end-use market called Distribution. The table below reflects the current and revised end-use market breakout.

For product class reporting, sales of powder metal products will be broken out and a new category of Alloy and Tool Steels will be added. The changes are intended to better segregate growth areas of premium products such as high temperature nickel-based special alloys, titanium products and powder metals, while also reflecting the anticipated product classes and businesses gained through the Latrobe acquisition. The table below reflects the current and revised product class categories

The recast historical financial information contained in Exhibits 99.1, 99.2, 99.3 and 99.4 to this Form 8-K does not represent a restatement of previously issued financial statements and has no impact on the Company’s historical consolidated financial position, results of operations or cash flows. The information contained in Exhibits 99.1, 99.2, 99.3 and 99.4 shall not be deemed to be incorporated by reference into any registration statement or other document pursuant to the Securities Exchange Act of 1933, as amended.

Net Sales Excluding Surcharge Revenues

This report includes discussions of net sales as adjusted to exclude the impact of raw material surcharges, which represents a financial measure that has not been determined in accordance with U.S. GAAP. We present and discuss this financial measure because management believes removing the impact of raw material surcharges from net sales provides a more consistent basis for comparing results of operations from period to period.

Forward-Looking Statements

These forward-looking statements are subject to risks and uncertainties that could cause actual results to differ from those projected, anticipated or implied.

Any of these factors could have an adverse and/or fluctuating effect on Carpenter’s results of operations.
