Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION Unless otherwise indicated, “we,” “us” and “our” mean SPX Technologies, Inc. and its consolidated subsidiaries (“SPX”). We prepared the condensed consolidated financial statements pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim reporting. As permitted under those rules and regulations, certain footnotes or other financial information normally required by accounting principles generally accepted in the United States (“GAAP”) can be condensed or omitted. The financial statements represent our accounts after the elimination of intercompany transactions and, in our opinion, include the adjustments (consisting only of normal and recurring items) necessary for their presentation. Unless otherwise indicated, amounts provided in these Notes pertain to continuing operations only (see Note 3 for information on discontinued operations). We account for investments in unconsolidated companies where we exercise significant influence but do not have control using the equity method. In determining whether we are the primary beneficiary of a variable interest entity (“VIE”), we perform a qualitative analysis that considers the design of the VIE, the nature of our involvement and the variable interests held by other parties to determine which party has the power to direct the activities of the VIE that most significantly impact the entity’s economic performance, and which party has the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. All of our VIE’s are immaterial, individually and in aggregate, to our condensed consolidated financial statements. Merger and Consummation of Holding Company Reorganization As of August 15, 2022, SPX Technologies, Inc. (the “Company”) is the successor registrant pursuant to Rule 12g-3(a) under the Securities Exchange Act of 1934, as amended, to SPX Corporation (“Legacy SPX”) as a result of the completion on August 15, 2022 of a holding company reorganization (the “Holding Company Reorganization”) effected as a merger of Legacy SPX with and into SPX Merger, LLC, a subsidiary of the Company. Each share of Legacy SPX’s common stock, par value $0.01 per share, issued and outstanding immediately prior to the consummation of the Holding Company Reorganization was automatically converted into an equivalent corresponding share of the Company’s common stock having the same designations, rights, powers and preferences and the qualifications, limitations and restrictions as the corresponding share of Legacy SPX common stock being converted. Accordingly, upon consummation of the Holding Company Reorganization, Legacy SPX stockholders became stockholders of the Company. The terms “SPX,” “we” and “our” include Legacy SPX for periods prior to the consummation of the Holding Company Reorganization as the context requires. Divestiture of Asbestos Liabilities and Certain Assets On November 1, 2022, we divested three wholly-owned subsidiaries that hold asbestos liabilities and certain assets, including related insurance assets, to Canvas Holdco LLC (“Canvas”), an entity formed by a joint venture of Global Risk Capital LLC and an affiliate of Premia Holdings Ltd. In connection with the divestiture (the “Asbestos Portfolio Sale”), the divested subsidiaries have agreed to indemnify us and our affiliates for their asbestos-related liabilities, which encompassed all of our consolidated asbestos-related liabilities and contingent liabilities immediately prior to the divestiture. These indemnification obligations are not subject to any cap or time limitation. As a result of this transaction, the Company divested all obligations with respect to pending and future asbestos claims relating to these matters. The board of managers of the divested subsidiaries each received a solvency opinion from an independent advisory firm that the divested subsidiaries were solvent after giving effect to the Asbestos Portfolio Sale. The agreement for the Asbestos Portfolio Sale contains customary representations and warranties with respect to the divested subsidiaries, the Company, and Canvas. Pursuant to the agreement, the Company and Canvas will each indemnify the other for breaches of representation and warranties or breaches of covenants, subject to certain limitations as set forth in the agreement. Refer to Note 15 for additional details. Acquisition of Cincinnati Fan On December 15, 2021, we completed the acquisition of Cincinnati Fan & Ventilator Co., Inc. (“Cincinnati Fan”), a leader in engineered air movement solutions, including blowers and critical exhaust systems. W e purchased Cincinnati Fan for cash consideration of $145.2, net of (i) cash acquired of $2.5 and (ii) an adjustment to the purchase price received during the second quarter of 2022 related to acquired working capital of $0.4. The post acquisition operating results of Cincinnati Fan are reflected within our HVAC reportable segment. Acquisition of ITL On March 31, 2022, we completed the acquisition of International Tower Lighting, LLC ( “ ITL ” ), a leader in the design and manufacture of highly-engineered Aids to Navigation systems, including obstruction lighting for telecommunications towers, wind turbines and numerous other terrestrial obstructions. We purchased ITL for cash consideration of $40.4, net of (i) cash acquired of $1.1 and (ii) an adjustment to the purchase price received during the third quarter of 2022 related to acquired working capital of $1.4. The post-acquisition operating results of ITL are reflected within our Detection and Measurement reportable segment. Acquisition of TAMCO On April 3, 2023, we completed the acquisition of T. A. Morrison & Co. Inc. ( “TAMCO” ), a market leader in motorized and non-motorized dampers that control airflow in large-scale specialty applications in commercial, industrial, and institutional markets . We purchased TAMCO for cash consideration of $125.5, inclusive of an adjustment to the purchase price of $0.2 paid during the third quarter of 2023 related to acquired working capital and net of cash acquired of $1.0. The post-acquisition operating results of TAMCO are reflected within our HVAC reportable segment. Acquisition of ASPEQ On June 2, 2023, we completed the acquisition of ASPEQ Heating Group ( “ASPEQ”), a leading provider of electrical heating solutions to customers in industrial and commercial markets. We purchased ASPEQ for cash consideration of $421.8, net of cash acquired of $0.9. The purchase price is subject to adjustment based upon the final calculation of working capital and cash as of the date of acquisition. The post-acquisition operating results of ASPEQ are reflected within our HVAC reportable segment. The assets acquired and liabilities assumed in the TAMCO and ASPEQ transactions have been recorded at estimates of fair value as determined by management, based on information available and assumptions as to future operations and are subject to change, primarily for the final assessment and valuation of certain income tax amounts. Other Preparing financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. Actual results could differ from these estimates. The unaudited information included in this Quarterly Report on Form 10-Q should be read in conjunction with the consolidated financial statements contained in our Annual Report on Form 10-K for the year ended December 31, 2022 (“our 2022 Annual Report on Form 10-K”). Interim results are not necessarily indicative of full year results. We establish actual interim closing dates using a fiscal calendar, which requires our businesses to close their books on the Saturday closest to the end of the first calendar quarter, with the second and third quarters being 91 days in length. Our fourth quarter ends on December 31. The interim closing dates for the first, second and third quarters of 2023 are April 1, July 1, and September 30, compared to the respective April 2, July 2, and October 1, 2022 dates. We had one less day in the first quarter of 2023 and will have one more day in the fourth quarter of 2023 than in the respective 2022 periods. It is not practicable to estimate the impact of the one less day on our consolidated operating results for the nine months ended September 30, 2023, when compared to the consolidated operating results for the respective 2022 period. Correction of Prior-Year Classification and Disclosure During the fourth quarter of 2022, we concluded that, although the assessment of our reportable segments was performed using the appropriate measures as defined by the Segment Reporting Topic of the Accounting Standards Codification (“Codification”), the disclosure of operating income for each of our reportable segments (“Segment Income”) was not consistent with the measure used by our Chief Operating Decision Maker (“CODM”) when evaluating the results of, or allocating resources to, our reportable segments. We previously disclosed that Segment Income was determined before considering impairments and special charges, long-term incentive compensation, certain other operating income/expense, and other indirect corporate expenses. Our CODM also excludes the impact of intangible asset amortization, inventory step-up charges, and certain other acquisition-related costs from Segment Income. Accordingly, Segment Income, as presented in Note 6, now excludes all of the items noted above. This change had no impact to the amounts previously presented in our condensed consolidated statements of operations for the three and nine months ended October 1, 2022. Although the impact of this change to previously disclosed Segment Income is not material, we revised the prior-year presentation to be consistent with the current-year disclosure. The impact of this change on the Segment Income previously presented for the three and nine months ended October 1, 2022 is summarized below: Three months ended October 1, 2022 Nine months ended October 1, 2022 As Previously Presented Effect of Change Current Presentation As Previously Presented Effect of Change Current Presentation Income: HVAC reportable segment $ 30.9 $ 2.2 $ 33.1 $ 71.7 $ 10.3 $ 82.0 Detection and Measurement reportable segment 25.7 4.6 30.3 63.2 13.9 77.1 Total income for reportable segments 56.6 6.8 63.4 134.9 24.2 159.1 Corporate expense 17.2 — 17.2 50.2 — 50.2 Acquisition related costs (1) — 0.1 0.1 — 1.1 1.1 Long-term incentive compensation expense 2.1 — 2.1 7.7 — 7.7 Amortization of intangible assets — 6.7 6.7 — 23.1 23.1 Special charges, net — — — 0.1 — 0.1 Other operating expense, net — — — 1.0 — 1.0 Consolidated operating income $ 37.3 $ — $ 37.3 $ 75.9 $ — $ 75.9 ___________________________ (1) Represents additional “Cost of products sold” related to the step-up of inventory (to fair value) acquired in connection with the ITL acquisition of $0.1 and $1.1 during the three and nine months ended October 1, 2022, respectively.

Accounting Standards Update and Change in Accounting Principle [Abstract]
NEW ACCOUNTING PRONOUNCEMENTS	NEW ACCOUNTING PRONOUNCEMENTS The following is a summary of new accounting pronouncements that apply or may apply to our business. The London Interbank Offered Rate (“LIBOR”) was discontinued on June 30, 2023. In an effort to address the various challenges created by such discontinuance, the Financial Accounting Standards Board (“FASB”) issued three amendments to existing guidance, Accounting Standards Update (“ASU”) No. 2020-04, No. 2021-01, and No. 2022-06, Reference Rate Reform. The amended guidance is designed to provide relief from the accounting analysis and impacts that may otherwise be required for modifications to agreements (e.g., loans, debt securities, derivatives, etc.) necessitated by the reference rate reform. It also provides optional expedients to enable companies to continue to apply hedge accounting to certain hedging relationships impacted by the reference rate reform. Application of the guidance in the amendments is optional, is only available in certain situations, and is only available for companies to apply until December 31, 2024. In conjunction with entering into an amended and restated credit agreement on August 12, 2022, we adopted this guidance with no material impact on our condensed consolidated financial statements.

Acquisitions and Discontinued Operations [Abstract]
AQUISITIONS AND DISCONTINUED OPERATIONS	ACQUISITIONS AND DISCONTINUED OPERATIONS Acquisition of ASPEQ As indicated in Note 1, on June 2, 2023, we completed the acquisition of ASPEQ for $421.8, net of cash acquired of $0.9. We financed the acquisition with available cash and borrowings under our senior credit facilities. The assets acquired and liabilities assumed have been recorded at preliminary estimates of fair value as determined by management, based on information currently available and on current assumptions as to future operations and are subject to change upon completion of the acquisition method of accounting. Final determination of the fair values of certain assets and liabilities will be completed within the measurement period of up to one year from the acquisition date, as permitted under GAAP. The following is a summary of the recorded preliminary fair values of the assets acquired and liabilities assumed for ASPEQ as of June 2, 2023: Assets acquired: Current assets, including cash and equivalents of $0.9 $ 42.1 Property, plant and equipment 10.6 Goodwill 168.9 Intangible assets 246.1 Other assets 1.3 Total assets acquired 469.0 Current liabilities assumed 11.3 Non-current liabilities assumed (1) 35.0 Net assets acquired $ 422.7 ___________________________ (1) Includes net deferred income tax liabilities and other liabilities of $34.0 and $1.0, respectively. The identifiable intangible assets acquired consist of customer relationships, trademarks, technology, and customer backlog of $142.3, $51.5, $47.8, and $4.5, respectively, with such amounts based on a preliminary assessment of the related fair values. We expect to amortize the customer relationships, technology, and customer backlog assets over 12.0, 16.0, and 1.0 years, respectively, with the trademarks acquired being indefinite lived. We acquired gross receivables of $18.0, which had a fair value at the acquisition date of $17.9 based on our estimates of cash flows expected to be recovered. The qualitative factors that comprise the recorded goodwill include expected market growth for ASPEQ’s existing operations, increased volumes achieved by selling ASPEQ’s products through existing SPX sales channels, procurement and operational savings and efficiencies, and various other factors. We expect none of the goodwill described above to be deductible for tax purposes. We recognized revenues and net losses for ASPEQ of $26.0 and $0.8, and $34.6 and $1.3, respectively, for the three and nine months ended September 30, 2023 with the net loss impacted by charges during the three and nine months ended September 30, 2023 of (i) $6.7 and $9.4, respectively, associated with amortization of the various intangible assets mentioned above and (ii) $2.5 and $3.6, respectively, associated with the excess fair value (over historical cost) of inventory acquired which has been subsequently sold. During the nine months ended September 30, 2023, we incurred acquisition-related costs for ASPEQ of $5.1, which have been recorded to “Selling, general and administrative” within our condensed consolidated statements of operations and “Corporate expense” within consolidated operating income in Note 6. The following unaudited pro forma information presents our results of operations for the three and nine months ended September 30, 2023 and October 1, 2022, respectively, as if the acquisition of ASPEQ had taken place on January 1, 2022. The unaudited pro forma financial information is not intended to represent or be indicative of our consolidated results of operations that would have been reported had the acquisition been completed as of the date presented, and should not be taken as representative of our future consolidated results of operations. The pro forma results include estimates and assumptions that management believes are reasonable; however, these results do not include any anticipated cost savings or expenses of the planned integration of ASPEQ. These pro forma results of operations have been prepared for comparative purposes only and include additional interest expense on the borrowings required to finance the acquisition, additional depreciation and amortization expense associated with fair value adjustments to the acquired property, plant and equipment and intangible assets, adjustments to reflect charges associated with acquisition-related costs and charges associated with the excess fair value (over historical cost) of inventory acquired and subsequently sold as if they were incurred during the first quarter of 2022, and the related income tax effects. Three months ended Nine months ended September 30, 2023 October 1, 2022 September 30, 2023 October 1, 2022 Revenues $ 448.7 $ 397.0 $ 1,319.0 $ 1,108.8 Income from continuing operations 39.8 9.0 118.6 23.5 Net income (loss) (16.3) (0.4) 63.9 6.4 Income from continuing operations per share of common stock: Basic $ 0.87 $ 0.20 $ 2.61 $ 0.52 Diluted $ 0.85 $ 0.20 $ 2.55 $ 0.51 Net income (loss) per share of common stock: Basic $ (0.36) $ (0.01) $ 1.40 $ 0.14 Diluted $ (0.35) $ (0.01) $ 1.37 $ 0.14 Other Acquisitions As indicated in Note 1, on March 31, 2022 and April 3, 2023, we completed the acquisitions of ITL and TAMCO, respectively. The pro forma effects of these acquisitions are not material to our condensed consolidated results of operations. Sale of Transformer Solutions Business On October 1, 2021, we completed the sale of SPX Transformer Solutions, Inc. which is reported as a discontinued operation for all periods presented. During the first quarter of 2022, we agreed to the final adjustment of the purchase price which resulted in a payment to the buyer of $13.9 and an increase to the gain on sale of $0.2 . Wind-Down of DBT Business We completed the wind-down of our DBT Technologies (PTY) LTD (“DBT”) business after ceasing all operations, including those related to two large power projects in South Africa — Kusile and Medupi, in the fourth quarter of 2021. As a result of completing the wind-down plan, we are reporting DBT as a discontinued operation for all periods presented. As previously disclosed, DBT had asserted claims against the remaining prime contractor on the large projects, Mitsubishi Heavy Industries Power — ZAF (f.k.a. Mitsubishi-Hitachi Power Systems Africa (PTY) LTD) (“MHI”), of approximately South African Rand 1,000.0 (or $52.1) and MHI had asserted, or issued letters of intent to claim for, alleged damages against DBT. Although it was reasonably possible that some loss may have been incurred in connection with these claims (which totaled approximately South African Rand 2,815.2 or $146.5), we were unable to estimate the potential loss or range of potential loss associated with these claims due to the (i) lack of support provided by MHI for these claims; (ii) complexity of contractual relationships between the end customer, MHI, and DBT; (iii) legal interpretation of the contract provisions and application of South African law to the contracts; and (iv) unpredictable nature of any dispute resolution processes that have occurred or may occur in connection with these claims. Although we have experienced success in enforcing and defending our rights through the dispute resolution process over the past few years (including the matters mentioned below), we have invested, and would have continued to invest, significant management and financial resources to defend and pursue these matters. On September 5, 2023, DBT and SPX entered into an agreement with MHI to resolve all claims between the parties with respect to the two large power projects in South Africa (the “Settlement Agreement”). The Settlement Agreement provides for full and final settlement and mutual release of all claims between the parties with respect to the projects, including any claim against SPX Technologies, Inc. as guarantor of DBT's performance on the projects. It also provides that the underlying subcontracts are terminated and all obligations of both parties under the subcontracts have been satisfied in full. In connection with the Settlement Agreement, we incurred a charge, net of tax, of $54.2 during the three months ended September 30, 2023. The charge included the write-off of $15.2 in net amounts due from MHI. Such charge is included in “Loss from discontinued operations, net of tax” for the three and nine months ended September 30, 2023. Prior to the Settlement Agreement, on February 22, 2021, a dispute adjudication panel issued a ruling in favor of DBT against MHI related to costs incurred in connection with delays on two units of the Kusile project. In connection with the ruling, DBT received South African Rand 126.6 (or $8.6 at the time of payment). This ruling was subject to final and binding arbitration in this matter. In March 2023, an arbitration tribunal upheld the decision of the dispute adjudication panel. As a result, the South African Rand 126.6 (or $6.8) was recorded as income during the quarter ended April 1, 2023, with such amount recorded within “Loss on disposition of discontinued operations, net of tax.” Additionally, in June 2023, the arbitration tribunal ruled DBT was entitled to recover $1.3 of legal costs incurred related to the arbitration. Such amount was recorded to “Loss on disposition of discontinued operations, net of tax” during the second quarter of 2023 with the cash payment received during the nine months ended September 30, 2023. Additionally, in May 2023, a separate arbitration tribunal ruled DBT was entitled to recover $5.5 of legal costs incurred related to a prior arbitration hearing. Such amount was recorded to “Loss on disposition of discontinued operations, net of tax” during the second quarter of 2023 with the cash payment received during the nine months ended September 30, 2023. The assets and liabilities of DBT have been included within “Assets of DBT and Heat Transfer” and “Liabilities of DBT and Heat Transfer,” respectively, on the condensed consolidated balance sheets as of September 30, 2023 and December 31, 2022. The major line items constituting DBT ’ s assets and liabilities as of September 30, 2023 and December 31, 2022 : September 30, 2023 December 31, 2022 ASSETS Cash and equivalents $ 1.1 $ 9.3 Accounts receivable, net 4.9 7.6 Other current assets 3.8 6.5 Property, plant and equipment: Buildings and leasehold improvements 0.2 0.2 Machinery and equipment 0.6 0.7 0.8 0.9 Accumulated depreciation (0.7) (0.8) Property, plant and equipment, net 0.1 0.1 Other assets — 19.1 Total assets of DBT $ 9.9 $ 42.6 LIABILITIES Accounts payable (1) $ 25.8 $ 1.4 Contract liabilities 2.0 3.6 Accrued expenses 7.4 22.0 Other long-term liabilities 4.1 4.6 Total liabilities of DBT $ 39.3 $ 31.6 ___________________________ (1) Includes DBT's remaining obligation under the Settlement Agreement to make a payment to MHI of South African Rand 480.9 (or $25.0 at September 30, 2023), due in September 2024. In connection with this remaining obligation, we entered into a foreign currency forward contract which we are accounting for as a fair value hedge. Refer to Note 13 for additional details. Wind-Down of the Heat Transfer Business We completed the wind-down of our SPX Heat Transfer (“Heat Transfer”) business in the fourth quarter of 2020. As a result of completing the wind-down plan, we are reporting Heat Transfer as a discontinued operation for all periods presented. The assets and liabilities of Heat Transfer have been included within “Assets of DBT and Heat Transfer” and “Liabilities of DBT and Heat Transfer,” respectively, on the condensed consolidated balance sheets as of September 30, 2023 and December 31, 2022. The major line items constituting Heat Transfer’s assets and liabilities as of September 30, 2023 and December 31, 2022 are shown below: September 30, 2023 December 31, 2022 ASSETS Other current assets $ 0.3 $ 0.2 Other assets 0.1 0.1 Total assets of Heat Transfer $ 0.4 $ 0.3 LIABILITIES Accounts payable $ 0.1 $ 0.1 Accrued expenses 0.1 0.1 Total liabilities of Heat Transfer $ 0.2 $ 0.2 Changes in estimates associated with liabilities retained in connection with a business divestiture (e.g., income taxes) may occur. As a result, it is possible that the resulting gains/losses on these and other previous divestitures may be materially adjusted in subsequent periods. For the three and nine months ended September 30, 2023 and October 1, 2022, results of operations from our businesses reported as discontinued operations were as follows: Three months ended Nine months ended September 30, 2023 October 1, 2022 September 30, 2023 October 1, 2022 DBT (1) Loss from discontinued operations $ (69.2) $ (5.7) $ (68.6) $ (14.2) Income tax benefit 13.2 0.8 14.1 2.3 Loss from discontinued operations, net (56.0) (4.9) (54.5) (11.9) All other (2) Loss from discontinued operations (0.1) (6.0) (0.2) (6.9) Income tax benefit — 1.5 — 1.7 Loss from discontinued operations, net (0.1) (4.5) (0.2) (5.2) Total Loss from discontinued operations (69.3) (11.7) (68.8) (21.1) Income tax benefit 13.2 2.3 14.1 4.0 Loss from discontinued operations, net $ (56.1) $ (9.4) $ (54.7) $ (17.1) ___________________________ (1) Loss for the three and nine months ended September 30, 2023 resulted primarily from the charge, and related income tax impacts, recorded in connection with the Settlement Agreement referred to above and legal costs incurred in connection with the various dispute resolution matters. This loss for the nine months ended September 30, 2023 was partially offset by the arbitration awards received, which are discussed above. Loss for the three and nine months ended October 1, 2022 resulted primarily from net legal costs, and related income tax impacts, incurred in connection with various dispute resolution matters related to the two large power projects. (2) Loss for the three and nine months ended September 30, 2023 resulted primarily from revisions to liabilities retained in connection with prior dispositions. Loss for the three and nine months ended October 1, 2022 resulted primarily from asbestos-related charges and revisions to liabilities, including income tax liabilities, retained in connection with prior dispositions. Net cash used in discontinued operations for the nine months ended September 30, 2023 related primarily to (i) cash payments of $25.3 made by DBT to MHI during the three months ended September 30, 2023 in connection with the Settlement Agreement, (ii) disbursements of $14.5 for professional fees and support costs incurred principally in connection with the claims resolved by the Settlement Agreement, and (iii) local taxes of $3.8 paid in South Africa, which we subsequently recovered during the fourth quarter of 2023, partially offset by recovery of legal costs we were awarded in arbitration

Revenue from Contract with Customer [Abstract]
REVENUES FROM CONTRACTS	REVENUES FROM CONTRACTS Disaggregated Revenues We disaggregate revenue from contracts with customers by major product line and based on the timing of recognition for each of our reportable segments, as we believe such disaggregation best depicts how the nature, amount, timing, and uncertainty of our revenues and cash flows are affected by economic factors, with such disaggregation presented below for the three and nine months ended September 30, 2023 and October 1, 2022: Three months ended September 30, 2023 Reportable Segments HVAC Detection and Measurement Total Major product lines Package and process cooling equipment and services, and engineered air movement solutions $ 170.8 $ — $ 170.8 Boilers, electrical heating, and ventilation 118.4 — 118.4 Underground locators, inspection and rehabilitation equipment, and robotic systems — 65.9 65.9 Communication technologies, aids to navigation, and transportation systems — 93.6 93.6 $ 289.2 $ 159.5 $ 448.7 Timing of Revenue Recognition Revenues recognized at a point in time $ 271.3 $ 130.7 $ 402.0 Revenues recognized over time 17.9 28.8 46.7 $ 289.2 $ 159.5 $ 448.7 Nine months ended September 30, 2023 Reportable Segments HVAC Detection and Measurement Total Major product lines Package and process cooling equipment and services, and engineered air movement solutions $ 502.4 $ — $ 502.4 Boilers, electrical heating, and ventilation 307.4 — 307.4 Underground locators, inspection and rehabilitation equipment, and robotic systems — 199.0 199.0 Communication technologies, aids to navigation, and transportation systems — 263.0 263.0 $ 809.8 $ 462.0 $ 1,271.8 Timing of Revenue Recognition Revenues recognized at a point in time $ 747.6 $ 386.2 $ 1,133.8 Revenues recognized over time 62.2 75.8 138.0 $ 809.8 $ 462.0 $ 1,271.8 Three months ended October 1, 2022 Reportable Segments HVAC Detection and Measurement Total Major product lines Package and process cooling equipment and services, and engineered air movement solutions $ 134.5 $ — $ 134.5 Boilers, electrical heating, and ventilation 93.3 — 93.3 Underground locators, inspection and rehabilitation equipment, and robotic systems — 61.5 61.5 Communication technologies, aids to navigation, and transportation systems — 81.2 81.2 $ 227.8 $ 142.7 $ 370.5 Timing of Revenue Recognition Revenues recognized at a point in time $ 212.2 $ 117.1 $ 329.3 Revenues recognized over time 15.6 25.6 41.2 $ 227.8 $ 142.7 $ 370.5 Nine months ended October 1, 2022 Reportable Segments HVAC Detection and Measurement Total Major product lines Package and process cooling equipment and services, and engineered air movement solutions $ 381.8 $ — $ 381.8 Boilers, electrical heating, and ventilation 257.8 — 257.8 Underground locators, inspection and rehabilitation equipment, and robotic systems — 194.1 194.1 Communication technologies, aids to navigation, and transportation systems — 197.9 197.9 $ 639.6 $ 392.0 $ 1,031.6 Timing of Revenue Recognition Revenues recognized at a point in time $ 588.1 $ 331.2 $ 919.3 Revenues recognized over time 51.5 60.8 112.3 $ 639.6 $ 392.0 $ 1,031.6 Contract Balances Our customers are invoiced for products and services at the time of delivery or based on contractual milestones, resulting in outstanding receivables with payment terms from these customers (“Contract Accounts Receivable”). In some cases, the timing of revenue recognition, particularly for revenue recognized over time, differs from when such amounts are invoiced to customers, resulting in a contract asset (revenue recognition precedes the invoicing of the related revenue amount) or a contract liability (payment from the customer precedes recognition of the related revenue amount). Contract assets and liabilities are generally classified as current. On a contract-by-contract basis, the contract assets and contract liabilities are reported net within our condensed consolidated balance sheets. Our contract balances consisted of the following as of September 30, 2023 and December 31, 2022: Contract Balances September 30, 2023 December 31, 2022 Change Contract Accounts Receivable (1) $ 301.5 $ 259.9 $ 41.6 Contract Assets 33.4 23.9 9.5 Contract Liabilities - current (66.8) (52.8) (14.0) Contract Liabilities - non-current (2) (3.8) (4.7) 0.9 Net contract balance $ 264.3 $ 226.3 $ 38.0 ___________________________ (1) Included in “Accounts receivable, net” within the accompanying condensed consolidated balance sheets. (2) Included in “Other long-term liabilities” within the accompanying condensed consolidated balance sheets. T he $38.0 in crease in our net contract balance from December 31, 2022 to September 30, 2023 was due primarily to revenue recognized during the period, partially offset by cash payments received from customers during the period as well as the inclusion of net contract assets acquired with the ASPEQ and TAMCO acquisitions. During the three and nine months ended September 30, 2023, we recognized revenues of $4.9 and $35.5, respectively, related to our contract liabilities at December 31, 2022. Performance Obligations As of September 30, 2023, the aggregate amount allocated to remaining performance obligations was $210.8. We expect to recognize revenue on approximately 76% and 89% of remaining performance obligations over the next 12 and 24 months, respectively, with the remaining recognized thereafter.

Segment Reporting [Abstract]
INFORMATION ON REPORTABLE SEGMENTS	INFORMATION ON REPORTABLE SEGMENTS We are a global supplier of highly specializ ed, engineered solutions with operations in 15 countries and sales in over 100 countries around the world. We have aggregated our operating segments into the following two reportable segments: HVAC and Detection and Measurement. The factors considered in determining our aggregated segments are the economic similarity of the businesses, the nature of products sold or services provided, production processes, types of customers, distribution methods, and regulatory environment. In determining our reportable segments, we apply the threshold criteria of the Segment Reporting Topic of the Codification. Segment Income is determined before considering, if applicable, impairment and special charges, long-term incentive compensation, certain other operating income/expense, other indirect corporate expenses, intangible asset amortization expense, inventory step-up charges, and certain other acquisition-related costs. This is consistent with the way our CODM evaluates the results of each segment. HVAC Reportable Segment Our HVAC reportable segment engineers, designs, manufactures, installs and services package and process cooling products and engineered air movement solutions for the HVAC industrial and power generation markets, as well as boilers and electrical heating and ventilation products for the residential and commercial markets. The primary distribution channels for the segment’s products are direct to customers, independent manufacturing representatives, third-party distributors, and retailers. The segment serves a customer base in North America, Europe, and Asia. Detection and Measurement Reportable Segment Our Detection and Measurement reportable segment engineers, designs, manufactures, services, and installs underground pipe and cable locators, inspection and rehabilitation equipment, robotic systems, transportation systems, communication technologies, and aids to navigation. The primary distribution channels for the segment’s products are direct to customers and third-party distributors. The segment serves a global customer base, with a strong presence in North America, Europe, Africa and Asia. Corporate Expense Corporate expense generally relates to the cost of our Charlotte, North Carolina corporate headquarters. Financial data for our reportable segments for the three and nine months ended September 30, 2023 and October 1, 2022 are presented below: Three months ended Nine months ended September 30, 2023 October 1, 2022 September 30, 2023 October 1, 2022 Revenues: HVAC reportable segment $ 289.2 $ 227.8 $ 809.8 $ 639.6 Detection and Measurement reportable segment 159.5 142.7 462.0 392.0 Consolidated revenues $ 448.7 $ 370.5 $ 1,271.8 $ 1,031.6 Income: HVAC reportable segment $ 58.3 $ 33.1 $ 161.2 $ 82.0 Detection and Measurement reportable segment 33.3 30.3 89.2 77.1 Total income for reportable segments 91.6 63.4 250.4 159.1 Corporate expense 13.0 17.2 44.2 50.2 Acquisition-related and other costs (1) 2.9 0.1 5.0 1.1 Long-term incentive compensation expense 3.4 2.1 10.0 7.7 Amortization of intangible assets 14.6 6.7 32.4 23.1 Special charges, net — — — 0.1 Other operating expense, net — — — 1.0 Consolidated operating income $ 57.7 $ 37.3 $ 158.8 $ 75.9 ___________________________ (1) Represents certain acquisition-related costs incurred of $2.9 and $5.0 during the three and nine months ended September 30, 2023, respectively, and $0.1 and $1.1 during the three and nine months ended October 1, 2022, respectively, including additional “Cost of products sold” related to the step-up of inventory (to fair value) acquired in connection with the ASPEQ acquisition of $2.5 and $3.6 during the three and nine months ended September 30, 2023, respectively, and the ITL acquisition of $0.1 and $1.1 during the three and nine months ended October 1, 2022, respectively.

In connection with the acquisitions of TAMCO and ASPEQ, which have definite-lived intangible assets as noted above, we updated our estimated annual amortization expense related to intangible assets to approximately $44.0 for the full year 2023 and $46.0 for 2024 and each of the four years thereafter. At September 30, 2023 , the net carrying value of intangible assets with determinable lives consisted of $343.0 in the HVAC reportable segment and $125.1 in the Detection and Measurement reportable segment. At September 30, 2023, trademarks with indefinite lives consisted of $156.5 in the HVAC reportable segment and $63.3 in the Detection and Measurement reportable segment. We review goodwill and indefinite-lived intangible assets for impairment annually during th e fourth quarter in conjunction with our annual financial planning process, with such testing based primarily on events and circumstances existing as of the end of the third quarter. In addition, we test goodwill for impairment on a more frequent basis if there are indications of potential impairment. In reviewing goodwill and indefinite-lived intangible assets for impairment, we initially perform a qualitative analysis. If there is an indication of impairment, we then perform a quantitative analysis. A significant amount of judgment is involved in determining if an indication of impairment has occurred between annual testing dates. Such indication may include: a significant decline in expected future cash flows; a significant adverse change in legal factors or the business climate; unanticipated competition; and a more likely than not expectation of selling or disposing all, or a portion, of a reporting unit. During the fourth quarter of 2022, we performed a quantitative analysis on the goodwill of our Cincinnati Fan reporting unit. The Cincinnati Fan analysis indicated that the fair value of its net assets exceeded the related carrying value by less than 10%. A change in assumptions used in Cincinnati Fan’s quantitative analysis (e.g., projected revenues and profit growth rates, discount rates, industry price multiples, etc.) could result in the reporting unit’s estimated fair value being less than the carrying value. If Cincinnati Fan is unable to achieve its current financial forecast, we may be required to record an impairment charge in a future period related to its goodwill. As of September 30, 2023, Cincinnati Fan’s goodwill totale d $54.8. We perform our annual trademarks impairment testing during the fourth quarter, or on a more frequent basis, if there are indications of potential impairment. The fair value of our trademarks is based on applying estimated royalty rates to projected revenues, with resulting cash flows discounted at a rate of return that reflects current market conditions (fair value based on unobservable inputs - Level 3, as defined in Note 17)

Retirement Benefits [Abstract]
EMPLOYEE BENEFIT PLANS	EMPLOYEE BENEFIT PLANSOn February 17, 2022, we transferred our existing liability under the SPX Postretirement Benefit Plans (the “Plans”) for a group of participants with retiree life insurance benefits to an insurance carrier for consideration payable to the insurance carrier of $10.0. Of this consideration, $9.0 was paid during the first quarter of 2022, with the remainder paid in the second quarter of 2022. This transaction resulted in a settlement charge of $0.7 recorded to “Other income (expense), net” during the first quarter of 2022. In addition, and in connection with this transfer, we remeasured the assets and liabilities of the Plans as of the transfer date, which resulted in a benefit of $0.4 recorded to “Other income (expense), net” for the three months ended April 2, 2022. Participants in the SPX U.S. Pension Plan (the “U.S. Plan”) are eligible to elect a lump-sum payment option in lieu of a future pension benefit. During the first half of 2022, $10.0 was paid to participants who elected lump-sum payments. This triggered a plan settlement which resulted in a charge to “Other income (expense), net” of $2.3 during the second quarter of 2022. In addition, we remeasured assets and liabilities of the U.S. Plan at the settlement date, which resulted in an actuarial loss of $1.5 recorded to “Other income (expense), net” for the three months ended July 2, 2022. Additional settlements by the U.S. Plan during the quarter ended October 1, 2022 resulted in a charge to “Other income (expense), net” of $2.0. We also remeasured the assets and liabilities of the U.S. Plan as of October 1, 2022, which resulted in an actuarial loss of $0.4 recorded to “Other income (expense), net” during the three months ended October 1, 2022. Net periodic benefit (income) expense for our pension and postretirement plans include the following components: Domestic Pension Plans Three months ended Nine months ended September 30, October 1, September 30, October 1, Interest cost $ 3.3 $ 2.9 $ 9.9 $ 7.5 Expected return on plan assets (2.2) (2.0) (6.6) (6.2) Settlement and actuarial losses (1) — 2.4 — 6.2 Net periodic pension benefit expense $ 1.1 $ 3.3 $ 3.3 $ 7.5 ___________________________ (1) For the three months ended October 1, 2022, consists of a settlement loss of $2.0 and an actuarial loss of $0.4.

Debt Disclosure [Abstract]
INDEBTEDNESS	INDEBTEDNESS The following summarizes our debt activity (both current and non-current) for the nine months ended September 30, 2023: December 31, Borrowings Repayments Other (6) September 30, Revolving loans (1) $ — $ 551.3 $ (455.0) $ — $ 96.3 Term loans (2)(3) 244.3 300.0 — (1.1) 543.2 Trade receivables financing arrangement (4) — 81.0 (49.0) — 32.0 Other indebtedness (5) 2.5 0.2 (0.6) 0.3 2.4 Total debt 246.8 $ 932.5 $ (504.6) $ (0.8) 673.9 Less: short-term debt 1.8 130.1 Less: current maturities of long-term debt 2.0 14.0 Total long-term debt $ 243.0 $ 529.8 ___________________________ (1) While not due for repayment until August 2027 under the terms of our senior credit agreement, we classify within current liabilities the portion of the outstanding balance that we believe will be repaid over the next year, with such amount based on an estimate of cash that is expected to be generated over such period. The revolving loan facility was utilized as the initial funding mechanism for the TAMCO and ASPEQ acquisitions and was partially repaid with the funds borrowed on the Incremental Term Loan (see additional discussion below). (2) As noted below, we amended our senior credit agreement on April 21, 2023, with the amendment making available an incremental term loan facility (“Incremental Term Loan”) in the amount of $300.0. The proceeds from the Incremental Term Loan were primarily used to fund the acquisition of ASPEQ. (3) The term loans are repayable in quarterly installments equal to 0.625% of the balance of $545.0, beginning in December 2023 and in each of the first three quarters of 2024, and 1.25% during the fourth quarter of 2024, all quarters of 2025 and 2026, and the first two quarters of 2027. The remaining balances are payable in full on August 12, 2027. Balances are net of unamortized debt issuance costs of $1.8 and $0.7 at September 30, 2023 and December 31, 2022, respectively. (4) Under this arrangement, we can borrow, on a continuous basis, up to $60.0, as available. Borrowings under this arrangement are collateralized by eligible trade receivables of certain of our businesses. At September 30, 2023, we had $18.0 of available borrowing capacity under this facility after giving effect to outstanding borrowings of $32.0. (5) Primarily includes balances under a purchase card program of $1.8 and $1.8 and finance lease obligations of $0.6 and $0.7 at September 30, 2023 and December 31, 2022, respectively. The purchase card program allows for payment beyond the normal payment terms for goods and services acquired under the program. As this arrangement extends the payment of these purchases beyond their normal payment terms through third-party lending institutions, we have classified these amounts as short-term debt. (6) “Other” includes the capitalization and amortization of debt issuance costs. During the second quarter of 2023 we capitalized $1.3 of debt issuance costs associated with the Incremental Term Loan. Senior Credit Facilities On April 21, 2023 (the “Incremental Amendment Effective Date”), we entered into an Incremental Facility Activation Notice (the “Incremental Amendment”) with Bank of America, N.A., as administrative agent (the “Administrative Agent”), and the lenders party thereto, which amends the Amended and Restated Credit Agreement, dated as of August 12, 2022 (as amended, the “Credit Agreement”), among the Company, the lenders party thereto, Deutsche Bank AG, as foreign trade facility agent, and the Administrative Agent. The Incremental Amendment provides for an Incremental Term Loan in the aggregate amount of $300.0, which was available in up to three drawings (subject to customary conditions) from the Incremental Amendment Effective Date to October 18, 2023. The proceeds of the Incremental Term Loan were available to be used to finance, in part, permitted acquisitions, to pay related fees, costs and expenses and for other lawful corporate purposes. The Incremental Term Loan will mature on August 12, 2027. We may voluntarily prepay the Incremental Term Loan, in whole or in part, without premium or penalty. In June 2023, we borrowed $300.0 under the Incremental Term Loan in connection with the ASPEQ acquisition. The interest rate applicable to the Incremental Term Loan is, at our option, equal to either (x) an alternate base rate (the highest of (a) the federal funds effective rate plus 0.50%, (b) the prime rate of Bank of America, N.A., and (c) the one-month Term SOFR rate plus 1.00%) or (y) the Term SOFR rate for the applicable interest period plus 0.10%, plus, in each case, an applicable margin percentage, which varies based on the Company’s Consolidated Leverage Ratio (defined in the Credit Agreement generally as the ratio of consolidated total debt (excluding the face amount of undrawn letters of credit, bank undertakings or analogous instruments and net of unrestricted cash and cash equivalents) at the date of determination to Consolidated EBITDA for the four fiscal quarters ended most recently before such date). SPX may elect interest periods of one three commitments for the Incremental Term Loan, payable quarterly at a per annum rate which also varies based on the Company’s Consolidated Leverage Ratio. The commitment fee rate and interest rate margins for the Incremental Term Loan are as follows: Consolidated Leverage Ratio Commitment Fee Term SOFR Loans ABR Loans Less than 2.00 to 1.0 0.225 % 1.500 % 0.500 % Greater than or equal to 2.00 to 1.0 but less than 3.00 to 1.0 0.250 % 1.625 % 0.625 % Greater than or equal to 3.00 to 1.0 0.275 % 1.875 % 0.875 % The Incremental Term Loan is guaranteed by certain domestic material subsidiaries of the Company and secured by a first priority pledge and security interest in 100% of the capital stock of our domestic subsidiaries or the domestic subsidiary guarantors and 65% of the voting capital stock (and 100% of the non-voting capital stock) of material first-tier foreign subsidiaries, all subject to certain exceptions and on a pari passu basis with the other credit facilities under the Credit Agreement. A detailed description of our remaining senior credit facilities under the Credit Agreement is included in our 2022 Annual Report on Form 10-K. At September 30, 2023, we had $392.9 of available borrowing capacity under our revolving credit facilities, after giving effect to borrowings under the domestic revolving loan facility of $96.3 and $10.8 reserved for outstanding letters of credit. In addition, at September 30, 2023, we had $9.7 of available issuance capacity under our foreign credit instrument facilities after giving effect to $15.3 reserved for outstanding letters of credit. The weighted-average interest rate of outstanding borrowings under the Credit Agreement was approximately 7.0% at September 30, 2023. At September 30, 2023, we were in compliance with all covenants of the Credit Agreement. In connection with an August 2022 amendment of the Credit Agreement, we recorded charges of $1.1 to “Loss on amendment/refinancing of senior credit agreement” related to the write-off of unamortized deferred financing costs totaling $0.7 and transaction costs of $0.4. Additionally, $1.5 of fees paid in connection with the August 2022 amendment were capitalized, with $1.2 related to our revolving loans and $0.3 related to the term loan.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE FINANCIAL INSTRUMENTS	DERIVATIVE FINANCIAL INSTRUMENTS Interest Rate Swaps We maintain interest rate swap agreements (“Swaps”) that have a remaining notional amount of $221.9, cover the period through November 202 4, and effectively convert this portion of the borrowings under our senior credit facilities to a fixed rate of 1.077%, plus the applicable margin. We have designated, and are accounting for, our Swaps as cash flow hedges. As of September 30, 2023 and December 31, 2022 , the unrealized gain, net of tax, recorded in accumulated other comprehensive income ( “ AOCI ”) was $8.1 and $11.0, respectively. In addition, the fair value of our Swaps was $10.8 (with $9.6 recorded as a current asset and $1.2 as a non-current asset) as of September 30, 2023 , and $14.7 (with $8.7 recorded as a current asset and $6.0 as a non-current asset) as of December 31, 2022 . Changes in the fair value of our Swaps are reclassified into earnings, as a component of interest expense, when the forecasted transaction impacts earnings. Currency Forward Contracts We manufacture and sell our products in a number of countries and, as a result, are exposed to movements in foreign currency exchange rates. Our objective is to preserve the economic value of non-functional currency-denominated cash flows and to minimize the impact of changes as a result of currency fluctuations. Our principal currency exposures relate to the South African Rand, British Pound Sterling, and Euro. From time to time, we enter into forward contracts to manage the exposure on contracts with forecasted transactions denominated in non-functional currencies and to manage the risk of transaction gains and losses associated with assets/liabilities denominated in currencies other than the functional currency of certain subsidiaries (“FX forward contracts”).

Long-Term Incentive Compensation Long-term incentive compensation awards may be granted to certain eligible employees or non-employee directors. A detailed description of the awards granted prior to 2023 is included in our 2022 Annual Report on Form 10-K. Awards granted on March 1 , 2023 to executive officers and other members of senior management were comprised of performance stock units (“PSU’s”), stock options, and time-based restricted stock units (“RSU’s”), while other eligible employees were granted PSU’s and RSU’s. The PSU’s are eligible to vest at the end of a three-year performance period, with performance based on the total return of our stock over the three-year performance period against a peer group within the S&P 600 Capital Goods Index. Stock options and RSU’s vest ratably over the three-year period subsequent to the date of grant.

CONTINGENT LIABILITIES AND OTHE

CONTINGENT LIABILITIES AND OTHER MATTERS	9 Months Ended
CONTINGENT LIABILITIES AND OTHER MATTERS	Sep. 30, 2023
Commitments and Contingencies Disclosure [Abstract]
CONTINGENT LIABILITIES AND OTHER MATTERS	CONTINGENT LIABILITIES AND OTHER MATTERS General Numerous claims, complaints and proceedings arising in the ordinary course of business have been asserted or are pending against us or certain of our subsidiaries (collectively, “claims”). These claims relate to litigation matters (e.g., class actions, derivative lawsuits and contracts, intellectual property and competitive claims), environmental matters, product liability matters (which, prior to the Asbestos Portfolio Sale, were predominately associated with alleged exposure to asbestos-containing materials), and other risk management matters (e.g., general liability, automobile, and workers’ compensation claims). Additionally, we may become subject to other claims of which we are currently unaware, which may be significant, or the claims of which we are aware may result in our incurring significantly greater loss than we anticipate. While we (and our subsidiaries) maintain property, cargo, auto, product, general liability, environmental, and directors’ and officers’ liability insurance and have acquired rights under similar policies in connection with acquisitions that we believe cover a significant portion of these claims, this insurance may be insufficient or unavailable (e.g., in the case of insurer insolvency) to protect us against potential loss exposures. Also, while we believe we are entitled to indemnification from third parties for some of these claims, these rights may be insufficient or unavailable to protect us against potential loss exposures. Our recorded liab ilities related to these matters, primarily associated with environmental matters, totaled $37.1 and $39.5 at September 30, 2023 and December 31, 2022, respectively. Of these amounts, $30.1 and $30.8 are included in “Other long-term liabilities” within our condensed consolidated balance sheets at September 30, 2023 and December 31, 2022 , respectively, with the remainder included in “Accrued expenses.” The liabilities we record for these matters are based on a number of assumptions, including historical claims and payment experience. While we base our assumptions on facts currently known to us, they entail inherently subjective judgments and uncertainties. As a result, our current assumptions for estimating these liabilities may not prove accurate, and we may be required to adjust these liabilities in the future, which could result in charges to earnings. These variances relative to current expectations could have a material impact on our financial position and results of operations. Asbestos Matters As indicated in Note 1, we completed the Asbestos Portfolio Sale on November 1, 2022, which resulted in the divestiture of three wholly-owned subsidiaries that hold asbestos liabilities and certain assets, including related insurance assets. As a result of this transaction, the Company divested all obligations with respect to pending and future asbestos claims relating to these subsidiaries. During the nine months ended October 1, 2022, our payments for asbestos-related claims, net of respective insurance recoveries of $27.7, were $20.2. During the three and nine months ended October 1, 2022, we recorded charges for asbestos-related matters of $21.7 and $24.0, respectively, with $16.5 and $18.8, respectively, recorded to continuing operations and the remainder to discontinued operations. Of such charges, $21.7 (continuing operations - $16.5 and discontinued operations - $5.2) resulted from a ruling by a North Carolina trial court, during the third quarter of 2022, that certain excess insurance carriers associated with our asbestos product liability matters are not required to cover the costs of defending suits that are dismissed without an indemnity payment. Large Power Projects in South Africa Overview - Since 2008, DBT had been executing on two large power projects in South Africa (Kusile and Medupi), on which it has completed its scope of work. During that time, the business environment surrounding these projects was difficult, as DBT, along with many other contractors on the projects, experienced delays, cost over-runs, and various other challenges associated with a complex set of contractual relationships among the end customer, prime contractors, various subcontractors (including DBT and its subcontractors), and various suppliers. Since substantial completion of the works, DBT’s remaining responsibilities related largely to resolution of various claims, primarily between itself and MHI, the remaining prime contractor. As noted below, SPX and DBT entered into a Settlement Agreement with MHI during the third quarter of 2023. Prior to the Settlement Agreement, DBT had asserted claims against MHI of approximately South African Rand 1,000.0 (or $52.1 ) and MHI had asserted, or issued letters of intent to claim for, alleged damages against DBT. Although it was reasonably possible that some loss may have been incurred in connection with these claims (which totaled approximately South African Rand 2,815.2 or $146.5 ), we were unable to estimate the potential loss or range of potential loss associated with these claims due to the (i) lack of support provided by MHI for these claims; (ii) complexity of contractual relationships between the end customer, MHI, and DBT; (iii) legal interpretation of the contract provisions and application of South African law to the contracts; and (iv) unpredictable nature of any dispute resolution processes that may have occurred in connection with these claims. Prior to the Settlement Agreement, DBT had experienced success in enforcing its rights through dispute resolution processes, including favorable arbitration rulings during 2023 related to awards for (i) costs incurred in connection with delays on the Kusile project of South African Rand 126.6 (or $6.8 ) during the first quarter of 2023 and (ii) recovery of legal costs related to arbitration proceedings of $6.8 during the second quarter of 2023, with such amounts recorded within “Loss on disposition of discontinued operations, net of tax.” There were no rulings or awards during the third quarter of 2023. Resolution of Remaining Prime Contractor Claims - We have invested, and would have continued to invest, significant management and financial resources to defend and pursue these matters. On September 5, 2023, SPX Technologies and DBT entered into the Settlement Agreement with MHI to affect the negotiated resolution of all outstanding claims between the parties with respect to the large power projects. The Settlement Agreement provides for full and final settlement and the mutual release of all claims between the parties with respect to the projects, including any claim against SPX Technologies, Inc. as guarantor of DBT’s performance on the projects. Refer to Note 3 for additional details. Claim against Surety - On February 5, 2021, DBT received payment of $6.7 on bonds issued in support of performance by one of DBT’s subcontractors. The subcontractor maintains a right to seek recovery of such amount and, thus, the amount received by DBT has not been reflected in our condensed consolidated statements of operations. Claim for Contingent Consideration Related to ULC Robotics (“ULC”) Acquisition In connection with our acquisition of ULC in September 2020, the seller of ULC was eligible for additional cash consideration of up to $45.0 upon achievement of certain operating and financial performance milestones. During the third quarter of 2021, we concluded that the operational and financial performance milestones noted above were not achieved and, thus, no amount is due to the seller. On August 23, 2022, the seller of ULC initiated a breach-of-contract lawsuit against us in the United States District Court for the Eastern District of New York claiming that it is entitled to a portion of the additional cash consideration linked to certain operating performance milestones totaling $15.0. SPX has numerous defenses against this claim and, thus, we do not believe we have a probable loss associated with the claim. Litigation Matters We are subject to other legal matters that arise in the normal course of business. We believe these matters are either without merit or of a kind that should not have a material effect, individually or in the aggregate, on our financial position, results of operations or cash flows; however, we cannot assure you that these proceedings or claims will not have a material effect on our financial position, results of operations or cash flows. Environmental Matters Our operations and properties are subject to federal, state, local and foreign regulatory requirements relating to environmental protection. It is our policy to comply fully with all applicable requirements. As part of our effort to comply, we have a comprehensive environmental compliance program that includes environmental audits conducted by internal and external independent professionals, as well as regular communications with our operating units regarding environmental compliance requirements and anticipated regulations. Based on current information, we believe that our operations are in substantial compliance with applicable environmental laws and regulations, and we are not aware of any violations that could have a material effect, individually or in the aggregate, on our business, financial condition, and results of operations or cash flows. We had liabilities for site investigation and/or remediation at 17 sites that we own or control, or formerly owned and controlled, as of September 30, 2023 and December 31, 2022. In addition, while we believe that we maintain adequate accruals to cover the costs of site investigation and/or remediation, we cannot provide assurance that new matters, developments, laws and regulations, or stricter interpretations of existing laws and regulations will not materially affect our business or operations in the future. Our environmental accruals cover anticipated costs, including investigation, remediation, and maintenance of clean-up sites. Our estimates are based primarily on investigations and remediation plans established by independent consultants, regulatory agencies and potentially responsible third parties. Accordingly, our estimates may change based on future developments, including new or changes in existing environmental laws or policies, differences in costs required to complete anticipated actions from estimates provided, future findings of investigation or remediation actions, or alteration to the expected remediation plans. It is our policy to revise an estimate once the revision becomes probable and the amount of change can be reasonably estimated. We generally do not discount our environmental accruals and do not reduce them by anticipated insurance recoveries. We take into account third-party indemnification from financially viable parties in determining our accruals where there is no dispute regarding the right to indemnification. In the case of contamination at offsite, third-party disposal sites, as of September 30, 2023 and December 31, 2022, we have been notified that we are potentially responsible and have received other notices of potential liability pursuant to various environmental laws at 9 sites, at which the liability has not been settled and all of which have been active in the past few years. These laws may impose liability on certain persons that are considered jointly and severally liable for the costs of investigation and remediation of hazardous substances present at these sites, regardless of fault or legality of the original disposal. These persons include the present or former owners or operators of the site and companies that generated, disposed of or arranged for the disposal of hazardous substances at the site. We are considered a “de minimis” potentially responsible party at most of the sites, and we estimate that our aggregate liability, if any, related to these sites is not material to our condensed consolidated financial statements. We conduct extensive environmental due diligence with respect to potential acquisitions, including environmental site assessments and such further testing as we may deem warranted. If an environmental matter is identified, we estimate the cost and either establish a liability, purchase insurance or obtain an indemnity from a financially sound seller; however, in connection with our acquisitions or dispositions, we may assume or retain significant environmental liabilities, some of which we may be unaware. The potential costs related to these environmental matters and the possible impact on future operations are uncertain due in part to the complexity of government laws and regulations and their interpretations, the varying costs and effectiveness of various clean-up technologies, the uncertain level of insurance or other types of recovery, and the questionable level of our responsibility. We record a liability when it is both probable and the amount can be reasonably estimated. In our opinion, after considering accruals established for such purposes, the cost of remedial actions for compliance with the present laws and regulations governing the protection of the environment are not expected to have a material impact, individually or in the aggregate, on our financial position, results of operations or cash flows. Self-insured Risk Management Matters We are self-insured for certain of our workers’ compensation, automobile, product and general liability, disability and health costs, and we believe that we maintain adequate accruals to cover our retained liability. Our accruals for risk management matters are determined by us, are based on claims filed and estimates of claims incurred but not yet reported, and generally are not discounted. We consider a number of factors, including third-party actuarial valuations, when making these determinations. We maintain third-party stop-loss insurance policies to cover certain liability costs in excess of predetermined retained amounts. This insurance may be insufficient or unavailable (e.g., because of insurer insolvency) to protect us against loss exposures.

INCOME AND OTHER TAXES

INCOME AND OTHER TAXES	Sep. 30, 2023
Income Tax Disclosure [Abstract]
INCOME AND OTHER TAXES	INCOME AND OTHER TAXES Uncertain Tax Benefits As of September 30, 2023 , we had gross unrecognized tax be nefits of $2.4 (net unrecognized tax benefits of $2.4). All of these net unrecognized tax benefits would impact our effective tax rate from continuing operations if recognized. We classify interest and penalties related to unrecognized tax benefits as a component of our income tax provision. As of September 30, 2023, gross accrued interest totaled $1.3 (net accrued interest of $1.2). As of September 30, 2023, we had no accrual for penalties included in our unrecognized tax benefits. Based on the outcome of certain examinations or as a result of the expiration of statutes of limitations for certain jurisdictions, we believe that within the next 12 months it is reasonably possible that our previously unrecognized tax benefits could decrease by up to $1.0. The previously unrecognized tax benefits relate to a variety of tax matters including transfer pricing and various state matters. Other Tax Matters For the three months ended September 30, 2023, we recorded an income tax provision of $12.4 on $48.1 of pre-tax income from continuing operations, resulting in an effective rate of 25.8%. This compares to an income tax benefit for the three months ended October 1, 2022 of $2.5 on $10.0 of pre-tax income from continuing operations, resulting in an effective rate of (25.0)%. The most significant items impacting the income tax provision for the third quarter of 2023 are (i) $0.8 of foreign withholding tax, and (ii) $0.3 of excess tax benefits associated with stock-based compensation awards that vested and/or were exercised during the period. The most significant item impacting the income tax benefit for the third quarter of 2022 was a tax benefit of $4.2 related to the release of valuation allowances recognized against certain deferred tax assets as we now expect these deferred tax assets to be realized. For the nine months ended September 30, 2023, we recorded an income tax provision of $31.5 on $144.6 of pre-tax income from continuing operations, resulting in an effective rate of 21.8%. This compares to an income tax provision for the nine months ended October 1, 2022 of $4.5 on $49.1 of pre-tax income from continuing operations, resulting in an effective rate of 9.2%. The most significant items impacting the income tax provision during the first nine months of 2023 and 2022 were (i) $1.8 and $4.2, respectively, of tax benefit related to the release of valuation allowances recognized against certain deferred tax assets as we now expect these deferred tax assets to be realized, (ii) $1.7 and $0.7, respectively, of excess tax benefits associated with stock-based compensation awards that vested and/or were exercised during the period, and (iii) $1.2 and $0.7, respectively, of tax benefits related to revisions to liabilities for uncertain tax positions. We perform reviews of our income tax positions on a continuous basis and accrue for potential uncertain positions when we determine that an uncertain position meets the criteria of the Income Taxes Topic of the Codification. Accruals for these uncertain tax positions are recorded in “Income taxes payable” and “Deferred and other income taxes” in the accompanying condensed consolidated balance sheets based on the expectation as to the timing of when the matters will be resolved. As events change and resolutions occur, these accruals are adjusted, such as in the case of audit settlements with taxing authorities. U.S. Federal income tax returns are subject to examination for a period of three years after filing the return. We are not currently under examination by the Internal Revenue Service and believe any contingencies in open years are adequately provided for. State income tax returns generally are subject to examination for a period of three to five years after filing the respective tax returns. The impact on such tax returns of any federal changes remains subject to examination by various states for a period of up to one year after formal notification to the states. We regularly have various state income tax returns in the process of examination. We believe any uncertain tax positions related to these examinations have been adequately provided for. We regularly have various foreign income tax returns under examination. We believe that any uncertain tax positions related to these examinations have been adequately provided for. An unfavorable resolution of one or more of the above matters could have a material impact on our financial position, results of operations, or cash flows in the quarter and year in which an adjustment is recorded or the tax is due or paid. As audits and examinations are still in process, the timing of the ultimate resolution and any payments that may be required for the above matters cannot be determined at this time.

FAIR VALUE

FAIR VALUE	9 Months Ended
FAIR VALUE	Sep. 30, 2023
Fair Value Disclosures [Abstract]
FAIR VALUE	FAIR VALUE Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In the absence of active markets for the identical assets or liabilities, such measurements involve developing assumptions based on market observable data and, in the absence of such data, internal information consistent with what market participants would use in a hypothetical transaction that occurs at the measurement date. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our market assumptions. Preference is given to observable inputs. These two types of inputs create the following fair value hierarchy: • Level 1 — Quoted prices for identical instruments in active markets. • Level 2 — Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable. • Level 3 — Significant inputs to the valuation model are unobservable. There were no changes during the periods presented to the valuation techniques we use to measure asset and liability fair values on a recurring or nonrecurring basis. There were no transfers between the three levels of the fair value hierarchy for the periods pres ented. Valuation Methods Used to Measure Fair Value on a Non-Recurring Basis Contingent Consideration for Sensors & Software and Enterprise Control Systems Acquisitions — In connection with the acquisition of Sensors & Software in 2020, the sellers were eligible for additional cash consideration of up to $3.7 , with payment of such contingent consideration dependent upon the achievement of certain milestones. Such contingent consideration totaled $1.3, and was paid during the quarter ended April 2, 2022. In connection with the acquisition of Enterprise Control Systems Ltd. in 2021, the seller was eligible for additional cash consideration of up to $15.2 , with payment of such contingent consideration dependent upon the achievement of certain milestones. During the first and second quarters of 2022, we concluded the probability of achieving the financial performance milestones had lessened due to a delay in the execution of certain large orders. Thus, during the quarters ended April 2, 2022 and July 2, 2022, we reduced the fair value/liability by $0.9 and $0.4, respectively, with such amounts recorded to “Other operating expense, net.” The estimated fair value of such contingent consideration was $0.0 at September 30, 2023 and December 31, 2022 as we determined no additional cash consideration was due to the seller. Goodwill, Indefinite-Lived Intangible and Other Long-Lived Assets — Certain of our non-financial assets are subject to impairment analysis, including long-lived assets, indefinite-lived intangible assets and goodwill. We review the carrying amounts of such assets whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable or at least annually for indefinite-lived intangible assets and goodwill. Any asset impairment would result in the asset being recorded at its fair value. Valuation Methods Used to Measure Fair Value on a Recurring Basis Derivative Financial Instruments — Our financial derivative assets and liabilities include interest rate swaps and FX forward contracts, valued using valuation models based on observable market inputs such as forward rates, inte rest rates, our own credit risk and the credit risk of our counterparties, which comprise investment-grade financial institutions. Based on these inputs, the derivative assets and liabilities are classified within Level 2 of the valuation hierarchy. We have not made any adjustments to the inputs obtained from the independent sources. Based on our continued ability to enter into forward contracts, we consider the markets for our fair value instruments active. We primarily use the income approach, which uses valuation techniques to convert future amounts to a single present amount. As of September 30, 2023, there has been no significant impact to the fair value of our derivative liabilities due to our own credit risk, as the related instruments are collateralized under our senior credit facilities. Similarly, there has been no significant impact to the fair value of our derivative assets based on our evaluation of our counterparties’ credit risks. Equity Security — We estimate the fair value of an equity security that we hold utilizing a practical expedient under existing guidance, with such estimated fair value based on our ownership percentage applied to the net asset value as provided quarterly by the investee. The value is updated annually, during the first quarter, based on the investee ’s most recent audited financial statements. During the three and nine months ended September 30, 2023 and October 1, 2022 , we re corded gains (losses) of $0.0 and $(7.4), respectively, and $3.6 and $(3.0), respectively, to “Other income (expense), net” to reflect the change in the estimated fair value of the equity security. As of September 30, 2023 and December 31, 2022, the equity security had an estimated fair value of $39.4 and $35.8, respectively. Indebtedness and Other — The estimated fair value of our debt instruments as of September 30, 2023 and December 31, 2022 approximated the related carrying values due primarily to the variable market-based interest rates for such instruments.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	We prepared the condensed consolidated financial statements pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim reporting. As permitted under those rules and regulations, certain footnotes or other financial information normally required by accounting principles generally accepted in the United States (“GAAP”) can be condensed or omitted. The financial statements represent our accounts after the elimination of intercompany transactions and, in our opinion, include the adjustments (consisting only of normal and recurring items) necessary for their presentation. Unless otherwise indicated, amounts provided in these Notes pertain to continuing operations only (see Note 3 for information on discontinued operations).
Variable Interest Entity	We account for investments in unconsolidated companies where we exercise significant influence but do not have control using the equity method. In determining whether we are the primary beneficiary of a variable interest entity (“VIE”), we perform a qualitative analysis that considers the design of the VIE, the nature of our involvement and the variable interests held by other parties to determine which party has the power to direct the activities of the VIE that most significantly impact the entity’s economic performance, and which party has the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. All of our VIE’s are immaterial, individually and in aggregate, to our condensed consolidated financial statements. Merger and Consummation of Holding Company Reorganization As of August 15, 2022, SPX Technologies, Inc. (the “Company”) is the successor registrant pursuant to Rule 12g-3(a) under the Securities Exchange Act of 1934, as amended, to SPX Corporation (“Legacy SPX”) as a result of the completion on August 15, 2022 of a holding company reorganization (the “Holding Company Reorganization”) effected as a merger of Legacy SPX with and into SPX Merger, LLC, a subsidiary of the Company. Each share of Legacy SPX’s common stock, par value $0.01 per share, issued and outstanding immediately prior to the consummation of the Holding Company Reorganization was automatically converted into an equivalent corresponding share of the Company’s common stock having the same designations, rights, powers and preferences and the qualifications, limitations and restrictions as the corresponding share of Legacy SPX common stock being converted. Accordingly, upon consummation of the Holding Company Reorganization, Legacy SPX stockholders became stockholders of the Company. The terms “SPX,” “we” and “our” include Legacy SPX for periods prior to the consummation of the Holding Company Reorganization as the context requires. Divestiture of Asbestos Liabilities and Certain Assets On November 1, 2022, we divested three wholly-owned subsidiaries that hold asbestos liabilities and certain assets, including related insurance assets, to Canvas Holdco LLC (“Canvas”), an entity formed by a joint venture of Global Risk Capital LLC and an affiliate of Premia Holdings Ltd. In connection with the divestiture (the “Asbestos Portfolio Sale”), the divested subsidiaries have agreed to indemnify us and our affiliates for their asbestos-related liabilities, which encompassed all of our consolidated asbestos-related liabilities and contingent liabilities immediately prior to the divestiture. These indemnification obligations are not subject to any cap or time limitation. As a result of this transaction, the Company divested all obligations with respect to pending and future asbestos claims relating to these matters. The board of managers of the divested subsidiaries each received a solvency opinion from an independent advisory firm that the divested subsidiaries were solvent after giving effect to the Asbestos Portfolio Sale. The agreement for the Asbestos Portfolio Sale contains customary representations and warranties with respect to the divested subsidiaries, the Company, and Canvas. Pursuant to the agreement, the Company and Canvas will each indemnify the other for breaches of representation and warranties or breaches of covenants, subject to certain limitations as set forth in the agreement. Refer to Note 15 for additional details.
Use of Estimates	Preparing financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. Actual results could differ from these estimates. The unaudited information included in this Quarterly Report on Form 10-Q should be read in conjunction with the consolidated financial statements contained in our Annual Report on Form 10-K for the year ended December 31, 2022 (“our 2022 Annual Report on Form 10-K”). Interim results are not necessarily indicative of full year results.
Fiscal Period	We establish actual interim closing dates using a fiscal calendar, which requires our businesses to close their books on the Saturday closest to the end of the first calendar quarter, with the second and third quarters being 91 days in length. Our fourth quarter ends on December 31. The interim closing dates for the first, second and third quarters of 2023 are April 1, July 1, and September 30, compared to the respective April 2, July 2, and October 1, 2022 dates. We had one less day in the first quarter of 2023 and will have one more day in the fourth quarter of 2023 than in the respective 2022 periods. It is not practicable to estimate the impact of the one less day on our consolidated operating results for the nine months ended September 30, 2023, when compared to the consolidated operating results for the respective 2022 period.
New Accounting Pronouncements	NEW ACCOUNTING PRONOUNCEMENTS The following is a summary of new accounting pronouncements that apply or may apply to our business. The London Interbank Offered Rate (“LIBOR”) was discontinued on June 30, 2023. In an effort to address the various challenges created by such discontinuance, the Financial Accounting Standards Board (“FASB”) issued three amendments to existing guidance, Accounting Standards Update (“ASU”) No. 2020-04, No. 2021-01, and No. 2022-06, Reference Rate Reform. The amended guidance is designed to provide relief from the accounting analysis and impacts that may otherwise be required for modifications to agreements (e.g., loans, debt securities, derivatives, etc.) necessitated by the reference rate reform. It also provides optional expedients to enable companies to continue to apply hedge accounting to certain hedging relationships impacted by the reference rate reform. Application of the guidance in the amendments is optional, is only available in certain situations, and is only available for companies to apply until December 31, 2024. In conjunction with entering into an amended and restated credit agreement on August 12, 2022, we adopted this guidance with no material impact on our condensed consolidated financial statements.
Inventories, Net	Inventories include material, labor and factory overhead costs and are reduced, when necessary, to estimated net realizable values.
Goodwill and Other Intangible Assets	We review goodwill and indefinite-lived intangible assets for impairment annually during th e fourth quarter in conjunction with our annual financial planning process, with such testing based primarily on events and circumstances existing as of the end of the third quarter. In addition, we test goodwill for impairment on a more frequent basis if there are indications of potential impairment. In reviewing goodwill and indefinite-lived intangible assets for impairment, we initially perform a qualitative analysis. If there is an indication of impairment, we then perform a quantitative analysis. A significant amount of judgment is involved in determining if an indication of impairment has occurred between annual testing dates. Such indication may include: a significant decline in expected future cash flows; a significant adverse change in legal factors or the business climate; unanticipated competition; and a more likely than not expectation of selling or disposing all, or a portion, of a reporting unit. During the fourth quarter of 2022, we performed a quantitative analysis on the goodwill of our Cincinnati Fan reporting unit. The Cincinnati Fan analysis indicated that the fair value of its net assets exceeded the related carrying value by less than 10%. A change in assumptions used in Cincinnati Fan’s quantitative analysis (e.g., projected revenues and profit growth rates, discount rates, industry price multiples, etc.) could result in the reporting unit’s estimated fair value being less than the carrying value. If Cincinnati Fan is unable to achieve its current financial forecast, we may be required to record an impairment charge in a future period related to its goodwill. As of September 30, 2023, Cincinnati Fan’s goodwill totale d $54.8. We perform our annual trademarks impairment testing during the fourth quarter, or on a more frequent basis, if there are indications of potential impairment. The fair value of our trademarks is based on applying estimated royalty rates to projected revenues, with resulting cash flows discounted at a rate of return that reflects current market conditions (fair value based on unobservable inputs - Level 3, as defined in Note 17)
Currency Forward Contracts	Currency Forward Contracts We manufacture and sell our products in a number of countries and, as a result, are exposed to movements in foreign currency exchange rates. Our objective is to preserve the economic value of non-functional currency-denominated cash flows and to minimize the impact of changes as a result of currency fluctuations. Our principal currency exposures relate to the South African Rand, British Pound Sterling, and Euro.
Potential Uncertain Positions	We perform reviews of our income tax positions on a continuous basis and accrue for potential uncertain positions when we determine that an uncertain position meets the criteria of the Income Taxes Topic of the Codification. Accruals for these uncertain tax positions are recorded in “Income taxes payable” and “Deferred and other income taxes” in the accompanying condensed consolidated balance sheets based on the expectation as to the timing of when the matters will be resolved. As events change and resolutions occur, these accruals are adjusted, such as in the case of audit settlements with taxing authorities. U.S. Federal income tax returns are subject to examination for a period of three years after filing the return. We are not currently under examination by the Internal Revenue Service and believe any contingencies in open years are adequately provided for. State income tax returns generally are subject to examination for a period of three to five years after filing the respective tax returns. The impact on such tax returns of any federal changes remains subject to examination by various states for a period of up to one year after formal notification to the states. We regularly have various state income tax returns in the process of examination. We believe any uncertain tax positions related to these examinations have been adequately provided for. We regularly have various foreign income tax returns under examination. We believe that any uncertain tax positions related to these examinations have been adequately provided for. An unfavorable resolution of one or more of the above matters could have a material impact on our financial position, results of operations, or cash flows in the quarter and year in which an adjustment is recorded or the tax is due or paid. As audits and examinations are still in process, the timing of the ultimate resolution and any payments that may be required for the above matters cannot be determined at this time.
Fair Value	Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In the absence of active markets for the identical assets or liabilities, such measurements involve developing assumptions based on market observable data and, in the absence of such data, internal information consistent with what market participants would use in a hypothetical transaction that occurs at the measurement date. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our market assumptions. Preference is given to observable inputs. These two types of inputs create the following fair value hierarchy: • Level 1 — Quoted prices for identical instruments in active markets. • Level 2 — Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable. • Level 3 — Significant inputs to the valuation model are unobservable. Goodwill, Indefinite-Lived Intangible and Other Long-Lived Assets — Certain of our non-financial assets are subject to impairment analysis, including long-lived assets, indefinite-lived intangible assets and goodwill. We review the carrying amounts of such assets whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable or at least annually for indefinite-lived intangible assets and goodwill. Any asset impairment would result in the asset being recorded at its fair value. Valuation Methods Used to Measure Fair Value on a Recurring Basis Derivative Financial Instruments — Our financial derivative assets and liabilities include interest rate swaps and FX forward contracts, valued using valuation models based on observable market inputs such as forward rates, inte rest rates, our own credit risk and the credit risk of our counterparties, which comprise investment-grade financial institutions. Based on these inputs, the derivative assets and liabilities are classified within Level 2 of the valuation hierarchy. We have not made any adjustments to the inputs obtained from the independent sources. Based on our continued ability to enter into forward contracts, we consider the markets for our fair value instruments active. We primarily use the income approach, which uses valuation techniques to convert future amounts to a single present amount. As of September 30, 2023, there has been no significant impact to the fair value of our derivative liabilities due to our own credit risk, as the related instruments are collateralized under our senior credit facilities. Similarly, there has been no significant impact to the fair value of our derivative assets based on our evaluation of our counterparties’ credit risks.

Schedule of Discontinued Operations	The following is a summary of the recorded preliminary fair values of the assets acquired and liabilities assumed for ASPEQ as of June 2, 2023: Assets acquired: Current assets, including cash and equivalents of $0.9 $ 42.1 Property, plant and equipment 10.6 Goodwill 168.9 Intangible assets 246.1 Other assets 1.3 Total assets acquired 469.0 Current liabilities assumed 11.3 Non-current liabilities assumed (1) 35.0 Net assets acquired $ 422.7 ___________________________ (1) Includes net deferred income tax liabilities and other liabilities of $34.0 and $1.0, respectively. The following unaudited pro forma information presents our results of operations for the three and nine months ended September 30, 2023 and October 1, 2022, respectively, as if the acquisition of ASPEQ had taken place on January 1, 2022. The unaudited pro forma financial information is not intended to represent or be indicative of our consolidated results of operations that would have been reported had the acquisition been completed as of the date presented, and should not be taken as representative of our future consolidated results of operations. The pro forma results include estimates and assumptions that management believes are reasonable; however, these results do not include any anticipated cost savings or expenses of the planned integration of ASPEQ. These pro forma results of operations have been prepared for comparative purposes only and include additional interest expense on the borrowings required to finance the acquisition, additional depreciation and amortization expense associated with fair value adjustments to the acquired property, plant and equipment and intangible assets, adjustments to reflect charges associated with acquisition-related costs and charges associated with the excess fair value (over historical cost) of inventory acquired and subsequently sold as if they were incurred during the first quarter of 2022, and the related income tax effects.

The revolving loan facility was utilized as the initial funding mechanism for the TAMCO and ASPEQ acquisitions and was partially repaid with the funds borrowed on the Incremental Term Loan (see additional discussion below). (2) As noted below, we amended our senior credit agreement on April 21, 2023, with the amendment making available an incremental term loan facility (“Incremental Term Loan”) in the amount of $300.0. The proceeds from the Incremental Term Loan were primarily used to fund the acquisition of ASPEQ. (3) The term loans are repayable in quarterly installments equal to 0.625% of the balance of $545.0, beginning in December 2023 and in each of the first three quarters of 2024, and 1.25% during the fourth quarter of 2024, all quarters of 2025 and 2026, and the first two quarters of 2027. The remaining balances are payable in full on August 12, 2027. Balances are net of unamortized debt issuance costs of $1.8 and $0.7 at September 30, 2023 and December 31, 2022, respectively. (4) Under this arrangement, we can borrow, on a continuous basis, up to $60.0, as available. Borrowings under this arrangement are collateralized by eligible trade receivables of certain of our businesses. At September 30, 2023, we had $18.0 of available borrowing capacity under this facility after giving effect to outstanding borrowings of $32.0. (5) Primarily includes balances under a purchase card program of $1.8 and $1.8 and finance lease obligations of $0.6 and $0.7 at September 30, 2023 and December 31, 2022, respectively. The purchase card program allows for payment beyond the normal payment terms for goods and services acquired under the program. As this arrangement extends the payment of these purchases beyond their normal payment terms through third-party lending institutions, we have classified these amounts as short-term debt. (6) “Other” includes the capitalization and amortization of debt issuance costs. During the second quarter of 2023 we capitalized $1.3 of debt issuance costs associated with the Incremental Term Loan.
