CARPENTER TECHNOLOGY REPORTS THIRD QUARTER

FISCAL YEAR 2021 RESULTS

PHILADELPHIA – April 29, 2021 – Carpenter Technology Corporation (NYSE: CRS) (the “Company”) today announced financial results for the fiscal third quarter ended March 31, 2021. For the quarter, the Company reported a net loss of $40.5 million, or $0.84 loss per diluted share. Excluding special items, adjusted loss per diluted share was $0.54 for the quarter.

“Our third quarter results were in-line with our expectations as we continue to weather near-term volume headwinds, as we had anticipated,” said Tony R. Thene, President and CEO of Carpenter Technology. “While current conditions remain challenging, we have recently completed multiple contract extensions in the Medical, Transportation and Aerospace and Defense end-use markets. We remain in close engagement with our customers and during the quarter began to see initial signs of recovery in some areas of our Aerospace and Defense end-use market. In addition, we continued to capitalize on solid demand in the Transportation end-use market and we benefited from signs of improving demand conditions in our Medical end-use market. We finished the quarter in a strong financial position with total liquidity of $538.8 million, including $244.2 million of cash on hand.”

“Looking ahead, we believe end-use market conditions will continue to improve as we move through calendar year 2021. The long-term outlook across our end-use markets remains strong and we are well positioned in each with critical material solutions to address our customers’ complex needs. We have deepened our customer relationships and continue to believe we will emerge from the pandemic a stronger company. Our core business is centered on delivering mission-critical material solutions and has been for over 130 years. Our investments in additive manufacturing and electrification capabilities further strengthen our sustainable long-term growth profile.”

Financial Highlights

Net sales for the third quarter of fiscal year 2021 were $351.9 million compared with $585.4 million in the third quarter of fiscal year 2020, a decrease of $233.5 million (negative 40 percent), on 39 percent lower volume. Net sales excluding surcharge were $298.1 million, a decrease of $196.9 million (negative 40 percent) from the same period a year ago.

Operating loss was $40.0 million compared to operating income of $58.7 million in the prior year period. Adjusted operating loss excluding special items was $29.7 million in the recent third quarter. Special items excluded from adjusted operating loss in the current quarter include restructuring and asset impairment charges, including inventory write-downs, of $7.6 million related to ongoing actions to reduce cost and narrow focus for the Additive business and $2.7 million of costs associated with COVID-19. These COVID-19 costs principally consist of direct incremental operating costs including outside services to execute enhanced cleaning protocols, additional personal protective equipment, isolation pay for production employees potentially exposed to COVID-19 and various operating supplies necessary to maintain the operations while keeping employees safe against possible exposure in the Company’s facilities.

Other expense, net was $8.3 million in the third quarter of fiscal year 2021, compared to $3.9 million in the third quarter of fiscal year 2020. The current quarter’s results include an $8.9 million non-cash settlement accounting charge associated with the Company’s largest qualified pension plan.

Cash provided from operating activities in the third quarter of fiscal year 2021 was $3.8 million, compared to $72.3 million in the same quarter last year. Free cash flow in the third quarter of fiscal year 2021 was negative $24.5 million, compared to positive $13.0 million in the same quarter last year. The decrease in operating cash flow primarily reflects the impact of lower earnings relative to the same quarter a year ago. This was partially offset by lower capital expenditures of $18.6 million in the third quarter of fiscal year 2021 compared to $49.7 million in the same quarter last year.

Total liquidity, including cash and available credit facility borrowings, was $538.8 million at the end of the third quarter of fiscal year 2021. This consisted of $244.2 million of cash and $294.6 million of available borrowings under the Company’s recently amended and extended secured credit facility.

The Company has two reportable segments, Specialty Alloys Operations (“SAO”) and Performance Engineered Products (“PEP”).

The SAO segment is comprised of Carpenter’s major premium alloy and stainless steel manufacturing operations. This includes operations performed at mills primarily in Reading and Latrobe, Pennsylvania and surrounding areas as well as South Carolina and Alabama.

The PEP segment is comprised of the Company’s differentiated operations. This segment includes the Dynamet titanium business, the Carpenter Additive business and the Latrobe and Mexico distribution businesses. Effective July 1, 2020, the Company’s Carpenter Powder Products business was merged into the Carpenter Additive business. The Amega West business was also part of the PEP segment however the business was divested during the quarter ended September 30, 2020. The businesses in the PEP segment are managed with an entrepreneurial structure to promote flexibility and agility to quickly respond to market dynamics. It is our belief this model will ultimately drive overall revenue and profit growth. The pounds sold data above for the PEP segment includes only the Dynamet and Additive businesses.

Corporate costs are comprised of executive and director compensation, and other corporate facilities and administrative expenses not allocated to the segments. Also included are items that management considers not representative of ongoing operations and other specifically identified income or expense items.

The service cost component of net pension expense, which represents the estimated cost of future pension liabilities earned associated with active employees, is included in the operating results of the business segments. The residual net pension expense is comprised of the expected return on plan assets, interest costs on the projected benefit obligations of the plans, and amortization of actuarial gains and losses and prior service costs and is included in other income (expense), net.

NON-GAAP FINANCIAL MEASURES

(in millions, except per share data)

(Unaudited)

Management believes that removing the impact of raw material surcharge from operating margin provides a more consistent basis for comparing results of operations from period to period, thereby permitting management to evaluate performance and investors to make decisions based on the ongoing operations of the Company. In addition, management believes that excluding the impact of special items from operating margin is helpful in analyzing the operating performance of the Company, as these items are not indicative of ongoing operating performance. Management uses its results excluding these amounts to evaluate its operating performance and to discuss its business with investment institutions, the Company’s board of directors and others.

Management believes that (loss) earnings per share adjusted to exclude the impact of the special items is helpful in analyzing the operating performance of the Company, as these items are not indicative of ongoing operating performance. Management uses its results excluding these amounts to evaluate its operating performance and to discuss its business with investment institutions, the Company’s board of directors and others.

Management believes that the free cash flow measure provides useful information to investors regarding the Company’s financial condition because it is a measure of cash generated which management evaluates for alternative uses.
