FOR IMMEDIATE RELEASE

IES Holdings Reports Fiscal 2018 Fourth Quarter and Year-End Results

HOUSTON — December 7, 2018 — IES Holdings, Inc. (or “IES” or the “Company”) (NASDAQ: IESC) today announced financial results for the quarter and year ended September 30, 2018.

Fourth Quarter and Fiscal Year 2018 Highlights

Management Commentary

Robert Lewey, President, stated, “We are pleased with our fiscal 2018 results and our prospects for 2019. We increased revenue, gross profit and operating income as compared to fiscal 2017, and in particular we experienced continued improvements in each of our segments during the second half of the year. Looking forward, we are entering 2019 with $482 million in backlog, an increase of 46% compared to the prior year, and believe that the capital we reinvested into our segments and completed acquisitions have us well-positioned to execute on this backlog, increase our market share and continue to capitalize on opportunities available to all four of our segments.”

Mr. Lewey continued, “During fiscal 2018, we largely focused on organic growth and execution. In our Infrastructure Solutions segment, the strength of our balance sheet allowed us to capture market share from underperforming and undercapitalized competitors. Margins and backlog improved within our Commercial & Industrial segment as the impact of winding down the underperforming Denver and Roanoke locations is largely behind us. Our Residential and Communications segments were both strengthened this year through the acquisitions of Electrical Contractors North and Azimuth Communications, respectively. Despite challenges in each of our segments with commodity prices and labor constraints, we have been successful in keeping up with increasing customer demand, while selectively increasing bid margins and increasing market share.”

Tracy McLauchlin, Chief Financial Officer, added, “During the year we invested $22 million in working capital in support of accelerating growth, $7 million in bolt-on acquisitions, and $2 million to repurchase our common stock. We believe that our strong balance sheet and available liquidity, as well as expected cash flow from both our legacy and acquired businesses, will support our growth strategy.”

Ms. McLauchlin continued, “During the fourth quarter of fiscal 2018 we recorded a $1.9 million charge in our Commercial & Industrial segment related to a litigation settlement on a multi-year project. Lastly, although our results during the year were impacted by the federal tax reform enacted in December 2017 and the recording of a non-cash charge of $31.3 million as a write-down of our net deferred tax assets and liabilities, this will not affect our continued use of our net deferred tax assets to reduce our net cash tax exposure and further support our growth.”

Net Operating Loss Carryforwards

The Company estimates that it has available Net Operating Loss Carryforwards (NOLs) for U.S. federal income tax purposes of approximately $355 million at September 30, 2018, including approximately $133 million resulting from the additional amortization of personal goodwill. The Company’s common stock is subject to a Rights Plan dated November 8, 2016, which is intended to assist in limiting the number of 5% or more owners of the Company’s common stock and thereby reduce the risk of a possible “change of ownership” under Section 382 of the Internal Revenue Code of 1986, as amended. Any such “change of ownership” under these rules would limit or eliminate the ability of the Company to use its existing NOLs for federal income tax purposes. There is no guarantee that the Rights Plan will achieve the objective of preserving the value or realization of the NOLs.

Stock Buyback Plan

The Company’s Board of Directors has authorized and previously announced a stock repurchase program for purchasing up to 1.5 million shares of our common stock from time to time. During the fiscal year ending September 30, 2018, the Company repurchased 100,627 shares at an average price of $15.41 per share. The Company had 724,804 shares remaining under its stock repurchase authorization at September 30, 2018.

Non-GAAP Financial Measures and Other Adjustments

This press release includes adjusted net income attributable to IES and, in the non-GAAP reconciliation table included herein, adjusted net income before taxes and adjusted earnings per share attributable to IES Holdings, Inc., each of which are financial measures not calculated in accordance with generally accepted accounting principles in the U.S. (“GAAP”). Management believes that these measures provide useful information to our investors by distinguishing certain nonrecurring events such as litigation settlements or noncash events such as our valuation allowances release and write-down of our net deferred tax assets, and that these measures, when reconciled to net income attributable to IES, which is the most directly comparable GAAP measure, help our investors to better identify underlying trends in the operations of our business and facilitate easier comparisons of our financial performance with prior and future periods and to our peers. Non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information calculated in accordance with GAAP. Investors are encouraged to review the reconciliation of these non-GAAP measures to their most directly comparable GAAP financial measures. A reconciliation of these non-GAAP financial measures to GAAP results has been provided in the financial tables included in this press release.

For further details on the Company’s financial results, please refer to the Company’s annual report on Form 10-K for the fiscal year ended September 30, 2018, to be filed with the Securities and Exchange Commission (“SEC”) by December 7, 2018, and any amendments thereto.
