October 25, 2024

BRISTOL, Conn., - Barnes Group Inc. (NYSE: B), a global provider of highly engineered products, differentiated industrial technologies, and innovative solutions, today reported financial results for the third quarter of 2024.

“In the third quarter, despite ongoing production delays from aircraft manufacturers, our Aerospace OEM business generated extraordinarily strong orders in anticipation of a future industry re-ramp. Meanwhile, our Aerospace aftermarket business continues to deliver robust performance on strong top-line growth. With the MB Aerospace integration and synergies progressing ahead of plan, we are delivering on our strategy to scale Aerospace and transform Barnes," said Thomas J. Hook, President and Chief Executive Officer of Barnes. “Over the last eighteen months, we have taken numerous actions to unlock the underlying value of Barnes by growing Aerospace, simplifying Industrial, investing in our businesses, and streamlining costs. Collectively, these actions have helped to position us for long-term profitable growth and led to outside interest in Barnes. As such, we are excited about our pending acquisition by Apollo Funds.”

Barnes to be Acquired by Apollo Funds

As announced on October 7, 2024, Barnes has entered into a definitive agreement to be acquired by funds managed by affiliates of Apollo Global Management, Inc. (NYSE: APO) (“Apollo”) (the “Apollo Funds”) in an all-cash transaction that values Barnes at an enterprise value of approximately $3.6 billion. Under the terms of the agreement, Barnes shareholders will receive $47.50 per share in cash. The transaction is subject to customary closing conditions, including approval by Barnes shareholders and receipt of required regulatory approvals. The transaction is expected to close in the first quarter of 2025.

Third Quarter 2024 Highlights

Sales of $388 million were up 7% versus the same quarter a year ago, with organicgrowth of 4%. The net beneficial impact of acquisition and divestiture related sales was approximately 3%, while foreign exchange increased sales by approximately 1%.

Adjusted operating income of $47.9 million increased 23% and adjusted operating margin of 12.3% increased 150 bps. Adjusted operating income excludes restructuring and transformation-related charges of $3.8 million, additional costs related to the sale of Associated Spring and Hänggi of $1.7 million, and MB Aerospace short-term purchase accounting adjustments of $0.6 million. Adjusted EBITDA was $76.9 million, up 16% from a year ago and adjusted EBITDA margin was 19.8%, up 140 bps.

Interest expense was $19.6 million, down 14% from $22.8 million a year ago due to last year’s one-time bridge financing fees of $9.5 million that were included in interest expense, offset in part by higher average borrowings from the purchase of MB Aerospace and a higher average interest rate given the recapitalization of the Company’s debt structure.

The Company's effective tax rate for the third quarter of 2024 was 110% driven by a $7.4 million tax provision related to the Income Inclusion Rule under Pillar Two which significantly reduces the benefit of tax holidays especially in Malaysia, a Canadian discrete tax item of $3.0 million, and the non-deductibility of transaction costs associated with the Company’s pending sale to Apollo Funds impacting tax by $1.6 million.

Net loss was $2.1 million, or -$0.04 per share, compared to a net loss of $21.7 million, or -$0.43 per share in the prior year. On an adjusted basis, net income per share of $0.09 was down 53% from $0.19. Adjusted net income per share excludes $0.06 of restructuring and transformation-related charges, a $0.03 adjustment to the loss on sale of Associated Spring and Hänggi, $0.03 of income tax effects on non-deductible merger costs, and $0.01 of MB Aerospace short-term purchase accounting adjustments.

Year-to-date cash provided by operating activities was $49.8 million versus $71.0 million a year ago. The decrease from the prior year was primarily due to an increase in working capital and divestiture related income tax payments. Capital expenditures of $41.8 million year-to-date increased $4.4 million over the prior year, driven by investments related to the Company’s restructuring program and investments for growth. Year-to-date free cash flow, adjusted for the tax payments related to the divestiture, was $20.4 million.

Segment Performance

Aerospace

Third quarter sales in the Aerospace segment were $232 million, up 49%. Organic sales increased 9%, and acquisition related sales added 39%. Aerospace original equipment manufacturing (“OEM”) sales increased 38%, while aftermarket sales increased 67%. On an organic basis, OEM sales decreased 1% and aftermarket sales increased 27%. Segment operating profit was $35.3 million versus $3.6 million a year ago. Adjusted operating profit of $36.3 million was up 55%, while adjusted operating margin increased 70 bps to 15.7%. Adjusted operating profit excludes restructuring and transformation related charges of $0.4 million and MB Aerospace short-term purchase accounting adjustments of $0.6 million. Adjusted operating profit benefited from the contribution of higher organic sales volumes, inclusive of pricing, the contribution of MB Aerospace sales, and positive productivity, partially offset by the amortization of long-term acquired intangibles. Aerospace adjusted EBITDA was $55.9 million, up 52%, and adjusted EBITDA margin was 24.1%, up 60 bps from a year ago.

Aerospace OEM backlog ended the third quarter at $1.80 billion, up 19% sequentially from June 2024 on a strong book-to-bill of 2.9 times.

Industrial

Third quarter sales in the Industrial segment were $156 million, down 24% primarily due to the sale of the Associated Spring and Hänggi businesses. On an organic basis, sales were up 1% from a year ago. Operating profit was $6.5 million versus $6.4 million in the prior year. Adjusted operating profit was $11.6 million, down 26%, and adjusted operating margin was 7.4%, down 20 bps. The lower adjusted operating profit reflects divested profits from the sale of the Associated Spring and Hänggi businesses and lower productivity, partially offset by positive pricing. Adjusted operating profit excludes restructuring and transformation-related charges of $3.4 million and additional costs related to the sale of Associated Spring and Hänggi of $1.7 million. Adjusted EBITDA was $21.6 million, down 25% from a year ago, and adjusted EBITDA margin was 13.9%, down 20 bps.

Leverage

Barnes’ “Net Debt to EBITDA” ratio, as defined in our credit agreements, was 3.35 times on September 30, 2024, down from 3.48 times on June 30, 2024.

Canceled Third Quarter 2024 Earnings Call and Suspension of Guidance

Given the pending acquisition of Barnes by Apollo Funds, the Company will not be conducting a third quarter 2024 conference call and webcast. In addition, Barnes is suspending its financial guidance for the full year 2024.

Non-GAAP Financial Measures

The financial statements included within this press release are prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP” or “U.S. GAAP”). The Company provides additional information with respect to certain non-GAAP financial measures, which include organic sales growth, adjusted operating profit, adjusted operating margin, adjusted EBITDA, adjusted EBITDA margin, adjusted EPS and Free Cash Flow. While these financial measures do not constitute U.S. GAAP measures, nor are they a substitute for U.S. GAAP measures, we believe they provide useful information to investors in understanding the ongoing operating performance of the Company. Investors should consider non-GAAP measures in addition to, not as a substitute for, or as superior to, measures of financial performance prepared in accordance with U.S. GAAP. Tables reconciling non-GAAP to GAAP financial measures, including forward looking outlook information, are presented at the end of this press release. The Company believes that these non-GAAP measures provide useful information to investors:

•Organic sales growth represents the total reported sales increase within the Company’s ongoing businesses less the impact of foreign currency translation and acquisitions/divestitures completed in the preceding twelve months. Management believes that organic sales growth provides an indication of baseline revenue performance and growth.

•Adjusted operating profit, adjusted operating margin and adjusted EPS provide an indication of our baseline profit performance. Management believes that these metrics are useful to investors as they exclude items that do not reflect our ongoing results.

•Adjusted EBITDA and Adjusted EBITDA margin provide adjusted earnings before interest, income tax, depreciation and amortization. Through acquisitions, the Company has incurred significant amortization expense (acquired intangible assets) and additional interest expense from debt-funded acquisitions. Management believes these financial metrics are useful to investors as they exclude the impact of these items.

•Free Cash Flow is defined by the Company as net cash provided by operating activities less capital expenditures. The Company believes that the free cash flow metric represents a measure of cash generated by business operations that can be used to invest in future growth, pay dividends, repurchase stock and reduce debt. This metric can also be used to evaluate the Company's ability to generate cash flow from business operations and the impact that this cash flow has on the Company's liquidity.

Notes:

(1) The Company defines free cash flow as net cash provided by operating activities less capital expenditures. In 2024, net cash provided by operating activities was negatively impacted by $12.5 million of estimated income tax payments related to the pre-tax gain related to the sale of the Associated Spring™ and Hänggi™ businesses (the "Businesses"). The proceeds from the sale are reflected in investing activities. The Company believes that the free cash flow metric is useful to investors and management as a measure of cash generated by business operations that can be used to invest in future growth, pay dividends, repurchase stock and reduce debt. This metric can also be used to evaluate the Company's ability to generate cash flow from business operations and the impact that this cash flow has on the Company's liquidity.

Notes:

(1) The Company has excluded the following from its "as adjusted" financial measurements for 2024: 1) charges related to restructuring/reduction in force actions at certain businesses and transformation related costs (consulting/professional fees related to business and portfolio transformation initiatives), 2) a pre-tax gain related to the divestiture of the Businesses, including $5.4M reflected within operating profit ($1.7 million of costs related to the divestiture in the third quarter), $1.5M reflected within other expense, net ($0.0 million in the third quarter) and a $23.7M charge reflected within income taxes ($0.0 million in the third quarter), 3) shareholder advisory costs, 4) short-term purchase accounting adjustments related to its MB Aerospace acquisition, 5) acquisition costs related to the acquisition of MB Aerospace, including $1.6M reflected within interest expense ($0.0 million in the third quarter), 6) goodwill impairment charge recorded in the second quarter of 2024 related to the Automation reporting unit, and 7) income tax effects of non-deductible merger costs. The Company has excluded the following from its "as adjusted" financial measurements for 2023: 1) charges related to restructuring/reduction in force actions at certain businesses and business transformation costs (consulting fees related to transformation initiatives), including $41.0M reflected within operating profit ($13.2 million in the third quarter) and ($1.1M) reflected within other expense (income), net ($0.0 million in the third quarter), 2) acquisition transaction costs related to the acquisition of MB Aerospace, including $11.4M reflected within operating profit ($7.8 million in the third quarter) and $9.6M reflected within interest expense, and 3) short-term purchase accounting adjustments related to its MB Aerospace acquisitions, including $8.0M all reflected within operating profit in the third quarter. The tax effects of the restructuring related actions, acquisition related actions, and shareholder advisory costs were calculated based on the respective tax jurisdictions and ranged from approximately 15% to approximately 30%. The goodwill impairment charge did not have a tax effect as it is not deductible for book purposes. Management believes that these adjustments provide the Company and its investors with an indication of our baseline performance excluding items that are not considered to be reflective of our ongoing results. Management does not intend results excluding the adjustments to represent results as defined by GAAP, and the reader should not consider it as an alternative measurement calculated in accordance with GAAP, or as an indicator of the Company's performance. Accordingly, the measurements have limitations depending on their use.
