Business Acquisitions

2026 Acquisition

On June 9, 2026 (the "NSI Industries Closing Date"), the Company acquired all of the issued and outstanding equity of NSI Electrical Buyer, Inc., a Delaware corporation ("NSI Industries") for $3.0 billion, net of cash acquired, subject to customary adjustments related to cash, indebtedness, working capital and transaction expenses. NSI Industries is a leading provider of electrical fittings, connectors, components and wire management products. NSI Industries has been added to the Electrical Solutions segment. NSI Industries has complementary product offerings that enhance Hubbell's Electrical Solutions portfolio, and fits with our long-term strategy to grow our offering of critical infrastructure solutions to our core electrical and utility customers. We have recognized intangible assets of $1,856.0 million and goodwill of $1,288.7 million as a result of the acquisition. The intangible assets will be amortized over a weighted average period of approximately 25 years.

The Company financed the acquisition of NSI Industries with net proceeds from borrowings under a new unsecured term loan facility in an aggregate principal amount of $900 million, the issuance of $1.9 billion aggregate principal amount of senior notes and issuances of commercial paper.

We determined the preliminary fair values of the customer relationships intangible assets using a multi-period excess earnings method. The significant assumptions used in determining the preliminary fair values of the customer relationships intangible assets included revenue growth rates, gross margin, operating margin, attrition rate, tax rate and discount rate. We determined the preliminary fair values of trade name and backlog intangible assets using an income approach. Accordingly, the fair value measurement of the customer relationships intangible assets, trade name, and backlog intangible assets are classified in Level 3 of the fair value hierarchy.

The NSI Industries acquisition has been accounted for as business combination and resulted in the recognition of goodwill. The goodwill relates to a number of factors implied in the purchase price, including the future earnings and cash flow potential of the business as well as the complementary strategic fit and resulting synergies that such business acquisition brings to the Company’s existing operations. For tax purposes, $58.3 million of the NSI Industries historical goodwill is deductible. The incremental goodwill created as a result of the acquisition is not deductible for tax purposes.

Preliminary Allocation of Consideration Transferred to Net Assets Acquired

The following table presents the preliminary determination of the fair values of identifiable assets acquired and liabilities assumed from the Company's 2026 acquisition of NSI Industries (in millions).

The final determination of the fair value of certain assets and liabilities will be completed within the applicable one year measurement period as required by FASB ASC Topic 805, “Business Combinations.” As the Company finalizes the fair values of assets acquired and liabilities assumed, additional purchase price adjustments may be recorded during the measurement period.

Fair value estimates are based on a complex series of judgments about future events and uncertainties and rely heavily on estimates and assumptions. The judgments used to determine the estimated fair value assigned to each class of assets acquired and liabilities assumed, as well as asset lives, can materially impact the Company's results of operations and financial position. The finalization of the purchase accounting assessment may result in a change in the valuation of assets acquired and liabilities assumed and may have a material impact on the Company's results of operations and financial position.


Accounts receivable	$	162.2
Inventories	120.1
Other current assets	5.2
Property, plant and equipment	60.5
Other non-current assets	34.9
Intangible assets	1,856.0
Accounts payable	(19.2)
Other accrued liabilities	(63.1)
Deferred tax liabilities, net	(405.8)
Other non-current liabilities	(31.4)
Goodwill	1,288.7
Total Estimate of Consideration Transferred, Net of Cash Acquired	$	3,008.1

The purchase price allocation to identifiable intangible assets acquired for the 2026 acquisition is as follows (in millions, except useful life amounts):


	Estimated Fair Value		Weighted Average Estimated Useful Life
Patents, tradenames and trademarks	$	65.0	20
Customer relationships	$	1,780.0	25
Backlog	$	11.0	1
Total	$	1,856.0

Customer relationships intangible assets acquired are amortized using an accelerated method that reflects the pattern in which economic benefits of the intangible assets are consumed and results in higher amortization in the earlier years of the asset's useful life.

Supplemental Pro-forma Data

The results of operations for the 2026 acquisition have been included in the Company’s consolidated financial statements for the period subsequent to the completion of the acquisition on the NSI Industries Closing Date. The NSI Industries acquisition contributed sales of approximately $35.4 million and operating income was not material for the period from the NSI Industries Closing Date through June 30, 2026.

The following supplemental pro-forma information presents consolidated results as if the acquisition had been completed on January 1, 2025. Following that approach, for the purpose of the pro-forma results presented in the tables below, certain costs incurred by the Company during 2026 have been reclassified into the pro-forma 2025 period. The following table summarizes the pro forma adjustments to increase or (decrease) reported results to arrive at the pro-forma results.



	Three Months Ended June 30,				Six Months Ended June 30,
(in millions)	2026		2025		2026		2025
Transaction costs incurred in 2026	$	21.1	$	—	$	21.1	$	(21.1)
Intangible amortization and inventory step up	$	(5.4)	$	(15.5)	$	(15.8)	$	(38.7)
Interest expense	$	(20.5)	$	(27.7)	$	(48.2)	$	(57.0)

The unaudited financial information in the table above reflects additional amortization that would have been recorded assuming the fair value adjustments for intangible assets have been applied starting on January 1, 2025. Additionally, these amounts reflect adjustments for additional interest expense that would have been incurred, as a result of incurring debt for the acquisition over the periods in the pro forma financial information. Transaction costs related to the NSI Industries acquisition that were incurred during the three months ended June 30, 2026 are reflected in the six months ended June 30, 2025, due to the timing of the transaction.

The pro-forma results were calculated by combining the results of the Company with the stand-alone results of the acquisition for the pre-acquisition periods, as described above:


	Three Months Ended June 30,				Six Months Ended June 30,
(in millions)	2026		2025		2026		2025

The supplemental pro-forma financial information does not reflect the actual performance of the 2026 acquisition in the periods presented and does not reflect the potential realization of cost savings relating to the integration of the acquisition with Hubbell. Further, the pro-forma data should not be considered indicative of the results that would have occurred if the acquisition and related financing had been consummated on January 1, 2025, nor are they indicative of future results.

2025 Acquisitions

In the first quarter of 2025, the Company acquired all of the issued and outstanding equity of Alliance USAcqCo 2, Inc., a Delaware Corporation (“Ventev”) for approximately $73 million, net of cash acquired. Ventev is a leading manufacturer and provider of a complete ecosystem of solutions to power, protect, and connect wireless networks. The Ventev business has been added to the Electrical Solutions segment. We have recognized intangible assets of $34.5 million and goodwill of $40.0 million as a result of the acquisition. The $34.5 million of intangible assets consists primarily of customer relationships and trade names and will be amortized over a weighted average period of approximately 17 years.

In the third quarter of 2025, the Company acquired all of the issued and outstanding equity of Nicor, Inc., a Texas corporation ("Nicor") for approximately $56 million, net of cash acquired. Nicor designs and manufactures water metering endpoint solutions to integrate and optimize advanced metering infrastructure networks. Such solutions include polymer meter box lids and covers. Nicor has been added to the Utility Solutions segment. We have recognized intangible assets of $18.6 million and goodwill of $31.4 million as a result of the acquisition. The $18.6 million of intangible assets consists primarily of customer relationships and a trade name and will be amortized over a weighted average period of approximately 18 years.

On October 1, 2025, the Company acquired all of the issued and outstanding equity of Power Rose Acquisition, Inc., a Delaware corporation ("Power Rose" and together with its subsidiaries, "DMC Power") for approximately $827 million, net of cash acquired. DMC Power is a provider of swaged connection systems and tooling for utility substation and transmission markets. DMC Power has been added to the Utility Solutions segment. We have recognized intangible assets of $364.0 million and goodwill of $471.8 million as a result of the acquisition. The $364.0 million of intangible assets consists primarily of $290.0 million of customer relationships, with the remaining $74.0 million consisting of developed technology, trade names and backlog. The intangible assets will be amortized over a weighted average period of approximately 21 years.

The Company financed the acquisition of DMC Power with net proceeds from borrowings under a new unsecured term loan facility in the aggregate principal amount of $600.0 million and issuances of commercial paper.

We determined the preliminary fair values of the customer relationships intangible assets using a multi-period excess earnings method. The significant assumptions used in determining the preliminary fair values of the customer relationships intangible assets included revenue growth rates, gross margin, attrition rate, and discount rate. We determined the preliminary fair values of the developed technology, trade name and backlog intangible assets using an income approach. Accordingly, the fair value measurement of the customer relationships intangible assets, developed technology, trade name, and backlog intangible assets are classified in Level 3 of the fair value hierarchy.

These business acquisitions have been accounted for as business combinations and have resulted in the recognition of goodwill. The goodwill relates to a number of factors implied in the purchase price, including the future earnings and cash flow potential of the business as well as the complementary strategic fit and resulting synergies that such business acquisition brings to the Company’s existing operations. The goodwill related to the Ventev, Nicor and DMC Power acquisitions is not deductible for tax purposes.

Accounting Policies [Abstract]

Basis of Presentation

The accompanying unaudited Condensed Consolidated Financial Statements of Hubbell Incorporated (“Hubbell”, the “Company”, “registrant”, “we”, “our” or “us”, which references include its divisions and subsidiaries) have been prepared in accordance with generally accepted accounting principles (“GAAP”) for interim financial information. Accordingly, they do not include all of the information and footnotes required by United States of America (“U.S.”) GAAP for audited financial statements. In the opinion of management, all adjustments consisting only of normal recurring adjustments considered necessary for a fair statement of the results of the periods presented have been included. Operating results for the six months ended June 30, 2026 are not necessarily indicative of the results that may be expected for the full year ending December 31, 2026.

The balance sheet at December 31, 2025 has been derived from the audited financial statements at that date but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements.

For further information, refer to the audited consolidated financial statements and footnotes thereto included in the Hubbell Incorporated Annual Report on Form 10-K for the year ended December 31, 2025.

International Emergency Economic Powers Act ("IEEPA") Tariffs

On February 20, 2026, the U.S. Supreme Court issued a ruling in Learning Resources, Inc. v. Trump invalidating certain tariffs previously imposed under the IEEPA. On April 20, 2026, the U.S. Customs and Border Protection (CBP) launched a system to process IEEPA tariff refund claims and the Company submitted claims for IEEPA tariffs that have been previously paid. Based on these actions, the Company may be eligible for refunds of certain tariffs paid during 2025 and the first quarter of 2026.

The Company has elected to use a gain contingency model to account for recoveries of previously paid IEEPA tariffs, in accordance with ASC 450-30 "Gain Contingencies". Under this model, a gain contingency is not recognized in the financial statements until the gain is realized or realizable. Tariff recoveries are reflected as a reduction of cost of goods sold for inventory that has already been sold. Subsequent to June 30, 2026, the Company received refunds for IEEPA tariffs previously paid totaling approximately $30 million, including an immaterial amount of interest. As of June 30, 2026 these amounts were not deemed to be realized or realizable and, accordingly, these amounts were not recognized in the condensed consolidated financial statements for the period ending June 30, 2026.

Supplier Finance Program Obligations

Payment Services Arrangements

The Company has ongoing agreements with financial institutions to facilitate the processing of vendor payables. Under these agreements, the Company pays the financial institution the stated amount of confirmed invoices from participating suppliers on their original maturity date. The terms of the vendor payables are not affected by vendors participating in these agreements. As a result, the amounts owed are presented as accounts payable in the Company’s Condensed Consolidated Balance Sheets, of which $107.1 million and $95.5 million was outstanding at June 30, 2026 and December 31, 2025, respectively. Either party may terminate the agreements with 30 days written notice. Cash flows under the program are reported in operating activities in the Company’s Condensed Consolidated Statements of Cash Flows.

Commercial Card Program

In 2021, the Company entered into an agreement with a financial institution that allows participating suppliers to receive payment for outstanding invoices through a commercial purchasing card sponsored by a financial institution. The Company is required to settle such outstanding invoices through a consolidated payment to the financial institution 15 days after the commercial card billing cycle. The Company receives the benefit of extended payment terms and a rebate from the financial institution. Either party may terminate the agreement with 60 days written notice. The amount outstanding to the financial institution is presented as short-term debt in the Company’s Condensed Consolidated Balance Sheets, of which, $1.7 million and $2.1 million was outstanding at June 30, 2026 and December 31, 2025, respectively. Cash flows under the program are reported in financing activities in the Company’s Condensed Consolidated Statements of Cash Flows.

Recently Issued Accounting Pronouncements Not Yet Adopted

In November 2024, the FASB issued ASU 2024-03, “Disaggregation of Income Statement Expenses (DISE),” which requires additional disclosure of the nature of expenses included in the income statement. The standard requires disclosures about specific types of expenses included in the expense captions presented on the face of the income statement as well as disclosures about selling expenses. The ASU is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. The requirements are required to be adopted prospectively with the option for retrospective application. The Company is assessing the impact of adopting this standard on its financial statements and disclosures.

In September 2025, the FASB issued ASU 2025-06, "Targeted Improvements to the Accounting for Internal-Use Software", which modernizes the accounting for software costs. The ASU is effective for public entities for fiscal years beginning after December 15, 2027, and interim periods for fiscal years beginning after December 15, 2027. The Company is assessing the impact of adopting this standard on its financial statements and disclosures.

In October 2025, the FASB issued ASU 2025-10, "Accounting for Government Grants Received by Business Entities", which establishes the accounting for business entities on the recognition, measurement, presentation, and disclosure of government grants. The ASU is effective for public entities for fiscal years beginning after December 15, 2028, and interim periods for fiscal years beginning after December 15, 2029. The Company is assessing the impact of adopting this standard on its financial statements and disclosures.

Stock-Based Compensation

6 Months Ended

Jun. 30, 2026

Share-Based Payment Arrangement [Abstract]

Stock-Based Compensation

As of June 30, 2026, the Company had various stock-based awards outstanding which were issued to executives and other key employees. The Company recognizes the grant-date fair value of all stock-based awards to employees over their respective requisite service periods (generally equal to an award’s vesting period), net of estimated forfeitures. A stock-based award is considered vested for expense attribution purposes when the employee’s retention of the award is no longer contingent on providing subsequent service. For those awards that vest immediately upon retirement eligibility, the Company recognizes compensation cost immediately for retirement-eligible individuals or over the period from the grant date to the date retirement eligibility is achieved, if less than the stated vesting period.

The Company’s long-term incentive program for awarding stock-based compensation includes a combination of restricted stock, stock appreciation rights (“SARs”), and performance shares of the Company’s common stock pursuant to the Hubbell Incorporated Incentive Award Plan (the “Award Plan”). Under the Award Plan, the Company may authorize up to 10.3 million shares of common stock to settle awards of restricted stock, performance shares, or SARs. The Company issues new shares to settle stock-based awards. During the three months ended March 31, 2026, the Company's grant of stock-based awards included restricted stock, SARs and performance shares. There were no material awards granted during the three months ended June 30, 2026.

Each of the compensation arrangements is discussed below.

Restricted Stock

The Company issues various types of restricted stock, of which the restricted stock awards are considered outstanding at the time of grant, as the award holders are entitled to dividends and voting rights. Unvested restricted stock awards are considered participating securities when computing earnings per share. Restricted stock unit award holders are not entitled to dividends or voting rights until settlement. Restricted stock grants are not transferable and are subject to forfeiture in the event of the recipient's termination of employment prior to vesting.

Restricted Stock Awards Issued to Employees - Service Condition

Restricted stock awards that vest based upon a service condition are expensed on a straight-line basis over the requisite service period. These awards generally vest either in three equal installments on each of the first three anniversaries of the grant date or on the third-year anniversary of the grant date. The fair value of these awards is measured by the average of the high and low trading prices of the Company’s common stock on the most recent trading day immediately preceding the grant date (“measurement date”).

In February 2026, the Company granted 25,422 restricted stock awards with a fair value per share of $517.58.

Restricted Stock Units Issued to Employees - Service Condition

Restricted stock units that vest based upon a service condition are expensed on a straight-line basis over the requisite service period. These awards generally vest in three equal installments on each of the first three anniversaries of the grant date. The fair value of these awards is measured by the average of the high and low trading prices of the Company’s common stock on the measurement date reduced by the present value of dividends expected to be paid during the requisite service period.

In February 2026, the Company granted 1,013 restricted stock units with a fair value per share of $501.47.

Stock Appreciation Rights

SARs grant the holder the right to receive, once vested, the value in shares of the Company's common stock equal to the positive difference between the grant price, as determined using the mean of the high and low trading prices of the Company’s common stock on the measurement date, and the fair market value of the Company’s common stock on the date of exercise. This amount is payable in shares of the Company’s common stock. SARs vest and become exercisable in three equal installments during the first three years following the grant date and expire ten years from the grant date.

In February 2026, the Company granted 50,881 SAR awards. The fair value of each SAR award was measured using the Black-Scholes option pricing model.

The following table summarizes the weighted-average assumptions used in estimating the fair value of the SARs granted during February 2026:

Grant Date

Expected Dividend Yield

Expected Volatility

Risk Free Interest Rate

Expected Term

Weighted Avg. Grant Date Fair Value of 1 SAR

February 2026

1.2%

24.9%

3.6%

4.8 years

$126.81

The expected dividend yield was calculated by dividing the Company’s expected annual dividend by the average stock price for the past three months. Expected volatilities are based on historical volatilities of the Company’s stock for a period consistent with the expected term. The expected term of SARs granted was based upon historical exercise behavior of SARs. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for the expected term of the award.

Performance Shares

Performance shares represent the right to receive a share of the Company’s common stock subject to the achievement of certain market or performance conditions established by the Company’s Compensation Committee and measured over a three-year period. Partial vesting in these awards may occur after separation from the Company for retirement eligible employees. Shares are not vested until approved by the Company’s Compensation Committee.

Performance Shares - Market Condition

In February 2026, the Company granted 6,831 performance shares that will vest subject to a market condition and service condition through the performance period. The market condition associated with the awards is the Company's total shareholder return (“TSR”) compared to the TSR generated by the companies that comprise the S&P Capital Goods 900 index over a three year performance period. Performance at target will result in vesting and issuance of the number of performance shares granted, equal to a 100% payout. Performance below or above target can result in issuance in the range of 0%-200% of the number of shares granted. Expense is recognized irrespective of the market condition being achieved.

The fair value of the performance share awards with a market condition for the 2026 grants was determined based upon a lattice model.

The following table summarizes the related assumptions used to determine the fair values of the performance share awards with a market condition granted during February 2026:

Grant Date

Stock Price on Measurement Date

Dividend Yield

Expected Volatility

Risk Free Interest Rate

Expected Term

Weighted Avg. Grant Date Fair Value

February 2026

$517.58

1.1%

32.1%

3.4%

2.9 years

$689.16

Expected volatilities are based on historical volatilities of the Company’s and members of the peer group's stock over the expected term of the award. The risk free interest rate is based on the U.S. Treasury yield curve in effect at the time of the grant for the expected term of the award.

Performance Shares - Performance Condition

In February 2026, the Company granted 13,903 performance shares that will vest subject to an internal Company-based performance condition and service requirement.

Fifty percent of these performance shares granted will vest based on Hubbell’s compounded annual growth rate of Net sales as compared to that of the companies that comprise the S&P Capital Goods 900 index. Fifty percent of these performance shares granted will vest based on achieved adjusted operating profit margin performance as compared to internal targets. Each of these performance conditions is measured over the same three-year performance period. The cumulative result of these performance conditions can result in a number of shares earned in the range of 0%-200% of the target number of shares granted.

The fair value of the award is measured based upon the average of the high and low trading prices of the Company's common stock on the measurement date reduced by the present value of dividends expected to be paid during the requisite service period. The Company expenses these awards on a straight-line basis over the requisite service period and based on an assessment of the performance achieved to date. The weighted average fair value per share was $501.47 for the awards granted during February 2026.

•Segment Net sales comprise sales to unaffiliated customers - inter-segment and inter-area sales are not significant and are eliminated in consolidation.

•Segment operating income consists of Net sales less operating expenses, including total corporate expenses, which are generally allocated to each segment on the basis of the segment's percentage of consolidated Net sales. Interest expense and investment income and other expense, net have not been allocated to segments as these items are centrally managed by the Company.

•General corporate assets not allocated to segments are principally cash, prepaid pensions, investments and deferred taxes. These assets have not been allocated as they are centrally managed by the Company.

Revenue

Revenue from Contract with Customer [Abstract]

Revenue

The Company recognizes revenue when performance obligations identified under the terms of contracts with its customers are satisfied, which generally occurs, for products, upon the transfer of control in accordance with the contractual terms and conditions of the sale. The majority of the Company’s revenue associated with products is recognized at a point in time when the product is shipped to the customer, with a relatively small amount of transactions, primarily in the Utility Solutions segment, recognized upon delivery of the product at the destination.

The Company also has performance obligations, primarily within the Utility Solutions segment, that are recognized over time due to the customized nature of the product and the Company's enforceable right to receive payment for work performed to date in the event of a cancellation. The Company uses an input measure to determine the extent of progress towards completion of the performance obligation, which the Company believes best depicts the transfer of control to the customer. Under this method, revenue recognition is primarily based upon the ratio of costs incurred to date compared with estimated total costs to complete.

Revenue from service contracts and post-shipment performance obligations is approximately one percent of total annual consolidated net revenue and those service contracts and post-shipment obligations are primarily within the Utility Solutions segment. Revenue from service contracts and post-shipment performance obligations is recognized when or as those obligations are satisfied. The Company primarily offers assurance-type standard warranties that do not represent separate performance obligations and on occasion will separately offer and price extended warranties that are separate performance obligations for which the associated revenue is recognized over-time based on the extended warranty period. The Company records amounts billed to customers for reimbursement of shipping and handling costs within revenue. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for as fulfillment costs and are included in cost of goods sold. Sales taxes and other usage-based taxes are excluded from revenue.

Certain of our businesses require a portion of the transaction price to be paid in advance of transfer of control. Advance payments are not considered a significant financing component as they are received less than one year before the related performance obligations are satisfied. In addition, in the Utility Solutions segment, certain businesses offer annual maintenance service contracts that require payment at the beginning of the contract period. These payments are treated as a contract liability and are classified in Other accrued liabilities in the Condensed Consolidated Balance Sheets. Once control transfers to the customer and the Company meets the revenue recognition criteria, the deferred revenue is recognized in the Condensed Consolidated Statements of Income. The deferred revenue relating to the annual maintenance service contracts is recognized in the Condensed Consolidated Statements of Income on a straight-line basis over the expected term of the contract.

The following table presents disaggregated revenue by business group. In September 2025, we internally reorganized certain businesses within our Electrical Solutions segment. The re-organization streamlines the organization and aligns the organization to better serve our customers. This change had no impact to our reportable segments. In conjunction with this change, prior period amounts have been reclassified to conform to the current organizational structure.

Contract Balances

Our contract liabilities consist of advance customer payments for products as well as deferred revenue on service obligations and extended warranties. Deferred revenue is included in Other accrued liabilities in the Condensed Consolidated Balance Sheets.

Contract liabilities were $158.7 million as of June 30, 2026 compared to $174.6 million as of December 31, 2025. The $15.9 million decrease in our contract liabilities balance was primarily due to the recognition of $75.1 million in revenue related to amounts that were recorded in contract liabilities at January 1, 2026 partially offset by a $59.2 million net increase in current year deferrals primarily due to timing of advance payments on certain orders. The ending balance of contract assets as of June 30, 2026 and December 31, 2025, was $66.4 million and $48.2 million, respectively, with the increase being driven by revenue recognized in excess of billings. Credit losses recognized on our receivables and contract assets were immaterial for the three and six months ended June 30, 2026.

- Definition

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer. Excludes insurance and lease contracts.

2026 Term Loan

On May 15, 2026, the Company entered into a Term Loan Agreement (the "2026 Term Loan Agreement") with a syndicate of lenders and JPMorgan Chase Bank, N.A., as administrative agent. On June 8, 2026, the Company borrowed $900 million under the 2026 Term Loan Agreement (the "2026 Term Loan") on an unsecured basis to finance a portion of the purchase price of the NSI Industries acquisition. The 2026 Term Loan was made in a single borrowing and will be due and payable on June 8, 2029. The 2026 Term Loan bears interest based on the Term SOFR Rate (as defined in the 2026 Term Loan Agreement), plus an applicable interest addition based on Hubbell's credit ratings. The interest rate on the 2026 Term Loan as of June 30, 2026 was 4.65%. Hubbell also paid to the lenders certain customary fees in connection with the 2026 Term Loan Agreement.

The 2026 Term Loan Agreement contains representations and warranties and affirmative and negative covenants customary for an unsecured financing of this type, as well as a financial covenant requiring that, as of the last day of each fiscal quarter, the ratio of total indebtedness to total capitalization shall not be greater than 65%. The Company was in compliance with this covenant as of June 30, 2026.

2025 Term Loan

On September 29, 2025, the Company entered into a Term Loan Agreement (the "2025 Term Loan Agreement") with a syndicate of lenders and JPMorgan Chase Bank, N.A., as administrative agent. On October 1, 2025, the Company borrowed $600 million under the 2025 Term Loan Agreement (the "2025 Term Loan") on an unsecured basis to finance the majority of the purchase price of the DMC Power acquisition. The 2025 Term Loan was made in a single borrowing and will be due and payable on September 29, 2028. The 2025 Term Loan bears interest based on the Term SOFR Rate (as defined in the 2025 Term Loan Agreement), plus an applicable interest addition based on Hubbell's credit ratings. The interest rate on the 2025 Term Loan as of June 30, 2026 was 4.68%. Hubbell also paid to the lenders certain customary fees in connection with the 2025 Term Loan Agreement.

The 2025 Term Loan Agreement contains representations and warranties and affirmative and negative covenants customary for an unsecured financing of this type, as well as a financial covenant requiring that, as of the last day of each fiscal quarter, the ratio of total indebtedness to total capitalization shall not be greater than 65%. The Company was in compliance with this covenant as of June 30, 2026.

2025 Credit Facility

On March 25, 2025, the Company, as borrower, and each foreign subsidiary borrower from time to time party thereto (collectively, the “Foreign Subsidiary Borrowers”) entered into a five-year credit agreement with a syndicate of lenders and JPMorgan Chase Bank, N.A., as administrative agent, that provides for a $1.0 billion committed unsecured revolving credit facility (the “Revolving Credit Agreement”). The obligations of the Foreign Subsidiary Borrowers (if any) under the Revolving Credit Agreement are guaranteed by the Company.

Commitments under the Revolving Credit Agreement may be conditionally increased to an aggregate amount not to exceed $1.5 billion. The Revolving Credit Agreement includes a $50.0 million sub-limit for the issuance of letters of credit. The sum of the dollar amount of loans and letters of credit to the Foreign Subsidiary Borrowers under the Revolving Credit Agreement may not exceed $100.0 million.

The interest rate applicable to borrowings under the Revolving Credit Agreement is either (i) the alternate base rate (as defined in the Revolving Credit Agreement) or (ii) the term SOFR rate (as defined in the Revolving Credit Agreement) plus an applicable margin based on the Company's credit ratings.

All revolving loans outstanding under the Revolving Credit Agreement will be due and payable on March 25, 2030. The Revolving Credit Agreement provides for up to two one-year maturity extensions. As of June 30, 2026, the credit facility was undrawn.

The Revolving Credit Agreement contains a sole financial covenant requiring that, as of the last day of each fiscal quarter, the ratio of total indebtedness to total capitalization shall not be greater than 65%. The Company was in compliance with this covenant as of June 30, 2026.

Restructuring Costs and Other

Restructuring and Related Activities [Abstract]

Restructuring Costs and Other

In the three and six months ended June 30, 2026, we incurred costs for restructuring actions initiated in 2026 as well as costs for restructuring actions initiated in prior years. Our restructuring actions are associated with cost reduction efforts that include the consolidation of manufacturing and distribution facilities, as well as workforce reductions. Restructuring costs include severance and employee benefits, asset impairments, accelerated depreciation, as well as facility closure, contract termination and certain pension costs that are directly related to restructuring actions. These costs are predominantly settled in cash from our operating activities and are generally settled within one year, with the exception of asset impairments, which are non-cash.

Standard Product Warranty Disclosure [Abstract]

Guarantees

The Company records a liability equal to the fair value of guarantees in accordance with the accounting guidance for guarantees. When it is probable that a liability has been incurred and the amount can be reasonably estimated, the Company accrues for costs associated with guarantees. The most likely costs to be incurred are accrued based on an evaluation of currently available facts and, where no amount within a range of estimates is more likely, the minimum is accrued. As of June 30, 2026 and December 31, 2025, the fair value and maximum potential payment related to the Company’s guarantees were not material.

The Company offers product warranties that cover defects on most of its products. These warranties primarily apply to products that are properly installed, maintained and used for their intended purpose. The Company accrues estimated warranty costs at the time of sale. Estimated warranty expenses, recorded in cost of goods sold, are based upon historical information such as past experience, product failure rates, or the estimated number of units to be repaired or replaced. Adjustments are made to the product warranty accrual as claims are incurred, additional information becomes known, or as historical experience indicates.

Changes in the accrual for product warranties during the six months ended June 30, 2026 and 2025 are set forth below (in millions):


	2026		2025
BALANCE AT JANUARY 1, (a)	$	34.0	$	41.7
Provision	5.9		6.4
Expenditures/payments/other	(6.4)		(6.9)
BALANCE AT JUNE 30, (a)	$	33.5	$	41.2

(a) Refer to Note 7 – Other Accrued Liabilities and Note 8 – Other Non-Current Liabilities for a breakout of short-term and long-term warranties.

Future amortization expense associated with these intangible assets is estimated to be $83.8 million for the remainder of 2026, $172.1 million in 2027, $172.8 million in 2028, $173.1 million in 2029, $169.9 million in 2030, and $166.1 million in 2031. The Company amortizes intangible assets with definite lives using either an accelerated method that reflects the pattern in which economic benefits of the intangible assets are consumed and results in higher amortization in the earlier years of the assets' useful lives, or using a straight line method. Approximately 94% of the gross value of definite-lived intangible assets follows an accelerated amortization method.

The Company completed its annual goodwill impairment test as of April 1, 2026. For each of the Company's reporting units, the Company elected to utilize the quantitative goodwill impairment testing process, as permitted by the accounting guidance, by comparing the estimated fair value of the reporting units to their carrying values. If the estimated fair value exceeds its carrying value, no impairment exists.

Goodwill impairment testing requires judgment, including the identification of reporting units, assigning assets and liabilities to reporting units and determining the fair value of each reporting unit. Significant judgment is required to estimate the fair value of reporting units, including estimating future cash flows, determining appropriate discount rates and other assumptions, including assumptions about secular economic and market conditions. The Company uses internal discounted cash flow models to estimate fair value. These cash flow estimates are derived from historical experience, third party end market data, and future long-term business plans and include assumptions of future sales growth, gross margin, operating margin, terminal growth rate, and the application of an appropriate discount rate. Significant changes in these estimates and assumptions could materially affect the determination of fair value and/or goodwill impairment for each reporting unit. The Company believes that its estimated aggregate fair value of its reporting units is reasonable when compared to the Company's market capitalization on the valuation date.

As of April 1, 2026, the impairment testing resulted in implied fair values for each reporting unit that significantly exceeded such reporting unit's carrying value, including goodwill. The Company did not have any reporting units with zero or negative carrying amounts.

The Company completed its annual impairment test of indefinite-lived intangible assets as of April 1, 2026. For the 2026 test, the Company elected to utilize the quantitative impairment testing process as permitted in the accounting guidance, by comparing the estimated fair value of the indefinite-lived intangible assets to their carrying values. If the estimated fair value of the indefinite-lived intangible assets exceeds their carrying value, no impairment exists. The estimated fair value was determined utilizing an income approach (relief from royalty method). Significant judgment is required to estimate the fair value of the indefinite-lived intangible assets, including assumptions for future revenues, discount rates, royalty rates, and other assumptions, including assumptions about secular economic and market conditions. Significant changes in these estimates and assumptions could affect the determination of fair value and/or impairment for each indefinite-lived intangible asset. As of April 1, 2026, the impairment testing resulted in estimated fair values for each indefinite-lived intangible asset that significantly exceeded the carrying values and there were no indefinite-lived intangible assets at risk of failing the quantitative impairment test.

Earnings Per Share [Abstract]

Earnings Per Share

The Company computes earnings per share using the two-class method, which is an earnings allocation formula that determines earnings per share for common stock and participating securities. Service-based and performance-based restricted stock awards granted by the Company are considered participating securities, as these awards contain a non-forfeitable right to dividends.

The following table sets forth the computation of earnings per share for the three and six months ended June 30, 2026 and 2025 (in millions, except per share amounts):

Accounting Policies [Abstract]
Basis of Presentation	The accompanying unaudited Condensed Consolidated Financial Statements of Hubbell Incorporated (“Hubbell”, the “Company”, “registrant”, “we”, “our” or “us”, which references include its divisions and subsidiaries) have been prepared in accordance with generally accepted accounting principles (“GAAP”) for interim financial information. Accordingly, they do not include all of the information and footnotes required by United States of America (“U.S.”) GAAP for audited financial statements. In the opinion of management, all adjustments consisting only of normal recurring adjustments considered necessary for a fair statement of the results of the periods presented have been included. Operating results for the six months ended June 30, 2026 are not necessarily indicative of the results that may be expected for the full year ending December 31, 2026. The balance sheet at December 31, 2025 has been derived from the audited financial statements at that date but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements. For further information, refer to the audited consolidated financial statements and footnotes thereto included in the Hubbell Incorporated Annual Report on Form 10-K for the year ended December 31, 2025.
Supplier Finance Program Obligations	Supplier Finance Program Obligations Payment Services Arrangements The Company has ongoing agreements with financial institutions to facilitate the processing of vendor payables. Under these agreements, the Company pays the financial institution the stated amount of confirmed invoices from participating suppliers on their original maturity date. The terms of the vendor payables are not affected by vendors participating in these agreements. As a result, the amounts owed are presented as accounts payable in the Company’s Condensed Consolidated Balance Sheets, of which $107.1 million and $95.5 million was outstanding at June 30, 2026 and December 31, 2025, respectively. Either party may terminate the agreements with 30 days written notice. Cash flows under the program are reported in operating activities in the Company’s Condensed Consolidated Statements of Cash Flows. Commercial Card Program In 2021, the Company entered into an agreement with a financial institution that allows participating suppliers to receive payment for outstanding invoices through a commercial purchasing card sponsored by a financial institution. The Company is required to settle such outstanding invoices through a consolidated payment to the financial institution 15 days after the commercial card billing cycle. The Company receives the benefit of extended payment terms and a rebate from the financial institution. Either party may terminate the agreement with 60 days written notice. The amount outstanding to the financial institution is presented as short-term debt in the Company’s Condensed Consolidated Balance Sheets, of which, $1.7 million and $2.1 million was outstanding at June 30, 2026 and December 31, 2025, respectively. Cash flows under the program are reported in financing activities in the Company’s Condensed Consolidated Statements of Cash Flows.
Recently Issued Accounting Pronouncements Not Yet Adopted	Recently Issued Accounting Pronouncements Not Yet Adopted In November 2024, the FASB issued ASU 2024-03, “Disaggregation of Income Statement Expenses (DISE),” which requires additional disclosure of the nature of expenses included in the income statement. The standard requires disclosures about specific types of expenses included in the expense captions presented on the face of the income statement as well as disclosures about selling expenses. The ASU is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. The requirements are required to be adopted prospectively with the option for retrospective application. The Company is assessing the impact of adopting this standard on its financial statements and disclosures. In September 2025, the FASB issued ASU 2025-06, "Targeted Improvements to the Accounting for Internal-Use Software", which modernizes the accounting for software costs. The ASU is effective for public entities for fiscal years beginning after December 15, 2027, and interim periods for fiscal years beginning after December 15, 2027. The Company is assessing the impact of adopting this standard on its financial statements and disclosures. In October 2025, the FASB issued ASU 2025-10, "Accounting for Government Grants Received by Business Entities", which establishes the accounting for business entities on the recognition, measurement, presentation, and disclosure of government grants. The ASU is effective for public entities for fiscal years beginning after December 15, 2028, and interim periods for fiscal years beginning after December 15, 2029. The Company is assessing the impact of adopting this standard on its financial statements and disclosures.

Fair Value Measurement

Fair Value Disclosures [Abstract]

Fair Value Measurement

Financial Instruments

Financial instruments which potentially subject the Company to significant concentrations of credit loss risk consist of trade receivables, cash equivalents and investments. The Company grants credit terms in the normal course of business to its customers. Due to the diversity of its product lines, the Company has an extensive customer base, including electrical distributors and wholesalers, electric utilities, equipment manufacturers, electrical contractors, telecommunication companies and retail and hardware outlets. As part of its ongoing procedures, the Company monitors the credit worthiness of its customers. Bad debt write-offs have historically been minimal. The Company places its cash and cash equivalents with financial institutions and limits the amount of exposure in any one institution.

At June 30, 2026, our accounts receivable balance was $1,150.9 million, net of allowances of $17.0 million. During the six months ended June 30, 2026, our allowances increased by approximately $3.1 million.

Investments

At June 30, 2026 and December 31, 2025, the Company had $82.1 million and $78.4 million, respectively, of available-for-sale municipal debt securities. These investments had an amortized cost of $82.0 million and $78.0 million, respectively. No allowance for credit losses related to our available-for-sale debt securities was recorded for the six months ended June 30, 2026 or June 30, 2025. As of June 30, 2026 and December 31, 2025, the unrealized losses attributable to our available-for-sale debt securities were $0.4 million and $0.4 million, respectively. The fair value of available-for-sale debt securities with unrealized losses was $30.4 million at June 30, 2026 and $20.5 million at December 31, 2025.

The Company also had trading securities of $34.9 million at June 30, 2026 and $32.5 million at December 31, 2025 that are carried on the balance sheets at fair value. Unrealized gains and losses associated with available-for-sale debt securities are reflected in Accumulated other comprehensive loss, net of tax, while unrealized gains and losses associated with trading securities are reflected in the Condensed Consolidated Statements of Income.

Fair value measurements

Fair value is defined as the amount that would be received for selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The FASB fair value measurement guidance established a fair value hierarchy that prioritizes the inputs used to measure fair value. The three broad levels of the fair value hierarchy are as follows:

Level 1 – Quoted prices (unadjusted) in active markets for identical assets or liabilities.

Level 2 – Quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly.

Level 3 – Unobservable inputs for which little or no market data exists, therefore requiring a company to develop its own assumptions.

(a) Money market funds are reflected in Cash and cash equivalents in the Condensed Consolidated Balance Sheets.

(b)Time deposits are reflected in current and long-term investments depending on their maturity date in the Condensed Consolidated Balance Sheets.

(c) Forward exchange contracts-Assets are reflected in Other current assets in the Condensed Consolidated Balance Sheets.

(d) Forward exchange contracts-(Liabilities) are reflected in Other accrued liabilities in the Consolidated Balance Sheets.

The methods and assumptions used to estimate the Level 2 fair values are as follows:

Forward exchange contracts – The fair value of forward exchange contracts is based on quoted forward foreign exchange prices at the reporting date.

Available-for-sale municipal bonds classified in Level 2 – The fair value of available-for-sale investments in municipal bonds is based on observable market-based inputs, other than quoted prices in active markets for identical assets.

Deferred compensation plans

The Company offers certain employees the opportunity to participate in non-qualified deferred compensation plans. A participant’s deferrals are invested in a variety of participant-directed debt and equity mutual funds that are classified as trading securities. The Company purchased $2.6 million and $3.1 million of trading securities related to these deferred compensation plans during each of the six months ended June 30, 2026 and 2025, respectively. As a result of participant distributions, the Company sold $2.9 million of these trading securities during the six months ended June 30, 2026 and $3.3 million during the six months ended June 30, 2025. The unrealized gains and losses associated with these trading securities are directly offset by the changes in the fair value of the underlying deferred compensation plan obligation.

Long-Term Debt

As of June 30, 2026 and December 31, 2025, the carrying value of long-term debt, net of unamortized discount and debt issuance costs, was $4,803.9 million and $2,036.3 million, respectively. The estimated fair value of the long-term debt as of June 30, 2026 and December 31, 2025 was $4,776.5 million and $2,008.3 million, respectively, using quoted market prices in active markets for similar liabilities (Level 2).
