Exhibit 99.1 Brett A. Cope, Powell’s Chairman and Chief Executive Officer, stated, “Commercial momentum across our key end markets continues to accelerate as Powell was awarded a record $934 million of new orders in the quarter and reported a book-to-bill ratio of 3.0x. Activity levels across Oil and Gas, Electric Utility and Commercial and Industrial end markets have remained very robust, highlighted in this most recent quarter by our previously announced mega data center order with a value in excess of $400 million, as well as two additional megaorders; one within the LNG end market that approximated $60 million and the other a Petrochemical order for roughly $75 million. The Powell team also continues to focus on strong project execution as we deliver our record backlog, demonstrated by a strong gross margin performance of 30.6%.” Third Quarter Fiscal 2026 Results Revenues totaled $312 million, an increase of 9% compared to $286.3 million in the prior year, and a sequential increase of 5% compared to $296.6 million in the second quarter of Fiscal 2026. The growth compared to the prior year was driven by higher revenue levels from the Commercial & Other Industrial market, which grew 54%, as well as from the Electric Utility market, which grew 18%. This was partially offset by lower revenue within the Petrochemical market, which declined 49%. Gross profit of $95.3 million, or 30.6% of revenue, increased 8% compared to $87.9 million, or 30.7% of revenue, in the prior year and increased sequentially by 8% compared to $87.9 million, or 29.6% of revenue in the second quarter of Fiscal 2026. The increases in gross profit were primarily driven by higher volume levels and a continued strong and stable pricing environment. New orders totaled $934 million compared to $362 million in the prior year and $490 million in the second quarter of Fiscal 2026. The increases were driven by improved bookings predominantly within the Commercial & Other Industrial, Oil & Gas, and Petrochemical markets. During the quarter, the Company was awarded three mega orders; one for a data center with a value exceeding $400 million related to a behind-the- meter design of on-site generation assets, a Petrochemical order with a value of approximately $75 million in the fertilizer industry, and a LNG order with a value of approximately $60 million to support the liquefaction and export of LNG along the U.S. Gulf Coast. Backlog totaled $2.4 billion as of June 30, 2026, an increase of 69% compared to $1.4 billion as of June 30, 2025, and a sequential increase of 35% compared to $1.8 billion as of March 31, 2026.

Exhibit 99.1 Net income of $52.2 million, or $1.42 per diluted share, increased 8% compared to $48.2 million, or $1.32 per diluted share in the prior year. The increase was the result of higher revenues coupled with strong gross margins during the quarter. Net income in the quarter increased sequentially by 14% compared to $45.9 million, or $1.25 per diluted share in the second quarter of Fiscal 2026. On April 2, 2026, Powell effected a three-for-one forward split of our common stock and proportionately increased the number of authorized common stock from 30,000,000 to 90,000,000. Each shareholder of record as of the close of trading on March 20, 2026 (the “Record Date”) received, after the close of trading on April 2, 2026, two additional shares for every one share held on the Record Date. Trading began on a split-adjusted basis at market open on April 6, 2026. OUTLOOK Commenting on the Company’s expectations for the remainder of Fiscal 2026, Cope added, “The outlook for each of our core end markets are highly favorable, supported by durable and diverse demand drivers, including the continuation of U.S. LNG in the global energy landscape, growth in utility generation coupled with ongoing grid strengthening initiatives, as well as increasing demand to support data centers and related AI capacity demand. We anticipate activity across each of our core markets will remain robust. Our near-to-midterm focus remains on ensuring that Powell is adequately positioned to address these thematic, secular tailwinds driving the growing demand for electrical distribution equipment and custom, engineered-to-order solutions.” Michael Metcalf, Powell’s Chief Financial Officer, commented, “Our strong project execution levels, combined with our growing backlog and its overall composition across our core end markets, make us confident that Powell will deliver another very strong year of financial results as we close out Fiscal 2026 and look ahead to Fiscal 2027. We expect that gross margins will maintain levels consistent to the trailing twelve months, while prudently adding capacity to support the acceleration in our backlog. The expansion of our Jacintoport fabrication yard is expected to be completed by the close of Fiscal 2026, and we anticipate production to ramp up as we leverage this additional capacity to support recent core industrial project awards. We are also evaluating greenfield capacity expansions incremental to our added leased capacity in Houston and Ohio, while prioritizing adequate returns and ensuring the optimal manufacturing footprint for Powell over the long term.” (1) (1) (1) (3) (3)
