(July 28, 2026) – Hubbell Incorporated (NYSE: HUBB) today reported operating results for the second quarter ended June 30, 2026. "Hubbell delivered strong performance in the second quarter, with double digit growth in sales, adjusted operating profit and adjusted earnings per share" said Gerben Bakker, Chairman, President and CEO. Mr. Bakker continued, "Our strong positions in attractive end markets, as well as continued execution on our strategy, are demonstrated by our strong second quarter and first half financial results. Megatrends in grid modernization, load growth and datacenter investment drove 10% organic growth in the second quarter, with visible demand strength across utility and electrical markets. Operationally, we are managing inflation effectively through price and productivity actions while investing in capacity expansion to serve our customers in high growth areas and deploying capital to further upgrade our portfolio in high growth and margin areas within our core." Mr. Bakker concluded, "Strong first half order trends provide visibility to our second half outlook, and we are increasing our full year outlook to reflect double digit growth in organic sales, adjusted operating profit and adjusted earnings per share at the midpoint of our range." 1

SECOND QUARTER FINANCIAL HIGHLIGHTS The comments and year-over-year comparisons in this segment review are based on second quarter results in 2026 and 2025. Utility Solutions segment net sales in the second quarter of 2026 increased 10% to $1,026 million compared to $936 million reported in the second quarter of 2025. Organic net sales increased approximately 6% in the quarter compared to the second quarter 2025. Grid Infrastructure net sales increased approximately 12% and Grid Automation net sales increased approximately 1%. Segment operating income in the second quarter of 2026 was $234 million, or 22.8% of net sales, compared to $218 million, or 23.3% of net sales, in the same period of 2025. Adjusted operating income was $263 million, or 25.6% of net sales, in the second quarter of 2026as compared to $239 million, or 25.5% of net sales, in the same period of the prior year. Changes in operating income and operating margin were primarily due to volume growth, the impact of acquisitions and favorable price and productivity, partially offset by higher cost inflation, raw material costs and tariffs. Electrical Solutions segment net sales in the second quarter of 2026 increased 25% to $686 million compared to $549 million reported in the second quarter of 2025. Organic net sales increased 18% in the quarter, while acquisitions added 6.5%. Segment operating income in the second quarter of 2026 was $115 million, or 16.7% of net sales, compared to $118 million, or 21.5% of net sales, in the same period of 2025. Adjusted operating income was $146 million, or 21.2% of net sales, in the second quarter of 2026as compared to $124 million, or 22.5% of net sales, in the same period of the prior year. Changes in operating income and operating margin were driven primarily by volume growth, the impact of acquisitions and favorable price realization and productivity, partially offset by higher cost inflation, raw material costs, tariffs and restructuring investment. Adjusted diluted EPS in the second quarter 2026 excluded $0.56 of amortization of acquisition-related intangible assets and $0.44 of transaction, integration, and separation costs. Adjusted diluted EPS in the second quarter 2025 excluded $0.36 of amortization of acquisition-related intangible assets and $0.01 of transaction, integration, & separation costs. 3

During the second quarter, the Company acquired all of the issued and outstanding equity of NSI Electrical Buyer, Inc. ("NSI Industries"), a leading provider of electrical fittings, connectors, components and wire management products, for approximately $3.0 billion, using 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. Net cash provided by operating activities was $250 million in the second quarter of 2026 versus net cash provided by operating activities of $261 million in the 2025 period. Free cash flow was $213 million in the second quarter of 2026 versus $221 million in the comparable period of 2025. 4

SUMMARY & OUTLOOK For the full year 2026, Hubbell anticipates total sales growth of 16-18% including organic sales growth of 9-11%. Hubbell expects 2026 GAAP diluted earnings per share in the range of $17.25 to $17.55 and adjusted diluted earnings per share (“Adjusted EPS”) in the range of $20.25 to $20.55. For the full year, Adjusted EPS excludes amortization of acquisition-related intangible assets, which the Company expects to be approximately $2.50 per share, and transaction, integration, and separation costs, which the Company expects to be approximately $0.50 per share. The Company believes Adjusted EPS is a useful measure of underlying performance in light of our acquisition strategy. The diluted earnings per share and Adjusted EPS ranges are based on an adjusted tax rate of 22.0% to 22.5% and include approximately $20 million of anticipated restructuring and related investment. The Company expects full year 2026 free cash flow conversion of approximately 90% on adjusted net income. 5

NON-GAAP DEFINITIONS References to "adjusted" operating measures exclude the impact of certain costs, gains or losses. Management believes these adjusted operating measures provide useful information regarding our underlying performance from period to period and an understanding of our results of operations without regard to items we do not consider a component of our core operating performance. Adjusted operating measures are non-GAAP measures, and include adjusted operating income, adjusted operating margin, adjusted net income attributed to Hubbell Incorporated, adjusted net income available to common shareholders, adjusted earnings per diluted share, and Adjusted EBITDA. These non-GAAP measures exclude, where applicable: • Amortization of all intangible assets associated with our business acquisitions, including inventory step-up amortization associated with those acquisitions. The intangible assets associated with our business acquisitions arise from the allocation of the purchase price using the acquisition method of accounting in accordance with Accounting Standards Codification 805, “Business Combinations.” These assets consist primarily of customer relationships, developed technology, trademarks and tradenames, and patents, as reported in Note 6—Goodwill and Other Intangible Assets, under the heading “Total Definite-Lived Intangibles,” within the Company’s audited Consolidated Financial Statements set forth in its Annual Report on Form 10-K for fiscal year ended December 31, 2025. The Company believes that the exclusion of these non-cash expenses because we believe it (i) enhances management’s and investors’ ability to analyze underlying business performance, (ii) facilitates comparisons of our financial results over multiple periods, and (iii) provides more relevant comparisons of our results with the results of other companies as the amortization expense associated with these assets may fluctuate significantly from period to period based on the timing, size, nature, and number of acquisitions. Although we exclude amortization of these acquired intangible assets and inventory step-up from our non-GAAP results, we believe that it is important for investors to understand that revenue generated, in part, from such intangibles is included within revenue in determining adjusted net income attributable to Hubbell Incorporated. 11
Page 12
• Transaction, integration, and separation costs associated with our business acquisitions and divestitures. The effect that acquisitions and divestitures may have on our results can fluctuate significantly based on the timing, size, and number of transactions, and therefore result in significant volatility in the costs to complete transactions and integrate or separate the businesses. Transaction costs are primarily professional services and other fees incurred to complete the transactions recognized within operating income, as well as $7.2 million of bridge financing costs in connection with the transactions recognized within interest expense. Integration and separation costs are the internal and external incremental costs directly relating to these activities for the acquired or divested business. The acquisition and integration of NSI, DMC Power and the acquisitions and disposition completed by the Company in the fourth quarter of 2023 resulted in a significant increase in transaction, integration and separation costs. As a result, we believe excluding such costs relating to these transactions provides useful and more comparable information for investors to better assess our operating performance from period to period. • Gains or losses on disposition of a business. The Company excludes these gains or losses because we believe they enhance management's and investors' ability to analyze underlying business performance and facilitates comparisons of our financial results over multiple periods. In the second quarter of 2025 the Company recognized a $0.4 million pre-tax loss on the disposition of a product line in the Electrical Solutions segment. • Income tax effects of the above adjustments, which are calculated using the statutory tax rate, taking into consideration the nature of the item and the relevant taxing jurisdiction, unless otherwise noted. Adjusted EBITDA is a non-GAAP measure that excludes the items noted above and also excludes the Other income (expense), net, Interest expense, net, and Provision for income taxes captions of the Condensed Consolidated Statement of Income, as well as depreciation and amortization expense. Net debt (defined as total debt less cash and investments) to total capital is a non-GAAP measure that we believe is a useful measure for evaluating the Company's financial leverage and the ability to meet its funding needs. Free cash flow is a non-GAAP measure that we believe provides useful information regarding the Company's ability to generate cash without reliance on external financing. In addition, management uses free cash flow to evaluate the resources available for investments in the business, strategic acquisitions and further strengthening the balance sheet. 12
Page 13
In connection with our restructuring and related actions, we have incurred restructuring costs as defined by U.S. GAAP, which are primarily 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. We also incur restructuring-related costs, which are costs associated with our business transformation initiatives, including the consolidation of back-office functions and streamlining our processes, and certain other costs and gains associated with restructuring actions. We refer to these costs on a combined basis as "restructuring and related costs", which is a non-GAAP measure. Organic net sales, a non-GAAP measure, represents Net sales according to U.S. GAAP, less Net sales from acquisitions and divestitures during the first twelve months of ownership or divestiture, respectively, less the effect of fluctuations in Net sales from foreign currency exchange. The period-over-period effect of fluctuations in Net sales from foreign currency exchange is calculated as the difference between local currency Net sales of the prior period translated at the current period exchange rate as compared to the same local currency Net sales translated at the prior period exchange rate. We believe this measure provides management and investors with a more complete understanding of the underlying operating results and trends of established, ongoing operations by excluding the effect of acquisitions, dispositions and foreign currency, as these activities can obscure underlying trends. When comparing Net sales growth between periods excluding the effects of acquisitions, business dispositions and currency exchange rates, those effects are different when comparing results for different periods. For example, because Net sales from acquisitions are considered inorganic from the date we complete an acquisition through the end of the first year following the acquisition, Net sales from such acquisitions are reflected as organic net sales thereafter. There are limitations to the use of non-GAAP measures. Non-GAAP measures do not present complete financial results. We compensate for this limitation by providing a reconciliation between our non-GAAP financial measures and the respective most directly comparable financial measure calculated and presented in accordance with GAAP. Because non-GAAP financial measures are not standardized, it may not be possible to compare these financial measures with other companies’ non-GAAP financial measures having the same or similar names. These financial measures should not be considered in isolation from, as substitutes for, or alternative measures of, reported GAAP financial results, and should be viewed in conjunction with the most comparable GAAP financial measures and the provided reconciliations thereto. We believe, however, that these non-GAAP financial measures, when viewed together with our GAAP results and related reconciliations, provide a more complete understanding of our business. We strongly encourage investors to review our consolidated financial statements and publicly filed reports in their entirety and not rely on any single financial measure. 13
Page 14
Reconciliations of each of these non-GAAP measures to the most directly comparable GAAP measure can be found in the tables below. When we provide our expectations for organic net sales, adjusted effective tax rate, adjusted diluted EPS and free cash flow on a forward-looking basis, a reconciliation of the differences between the non-GAAP expectations and the corresponding GAAP measures (expected net sales, effective tax rate, diluted EPS and net cash flows provided by operating activities) generally is not available without unreasonable effort due to potentially high variability, complexity and low visibility as to the items that would be excluded from the GAAP measure in the relevant future period, such as unusual gains and losses, fluctuations in foreign currency exchange rates, the impact and timing of potential acquisitions and divestitures, certain financing costs, and other structural changes or their probable significance. The variability of the excluded items may have a significant, and potentially unpredictable, impact on our future GAAP results. 14
