FOR IMMEDIATE RELEASE

IES Holdings Reports Fiscal 2019 First Quarter Results

First Quarter 2019 Highlights

Management Commentary

Robert Lewey, President, stated, “Our strong first quarter operating results, reflected by the significant 217% increase in operating income compared with the same period a year ago, demonstrates the focused execution of our strategy. In particular, our Communications segment benefitted from strong demand for its technology infrastructure services and excellent project execution, which is highlighted by robust revenue and operating margin increases. As we have grown we have also been successful in leveraging our SG&A expenses, especially at corporate, with consolidated SG&A as a percentage of revenue decreasing to 13.2%. Looking forward, we expect to see continued profitable growth from our backlog of $538 million, which is up $201 million from a year ago, reflecting strong demand and a positive outlook across our markets. We remain optimistic that we will build upon these results with continuing improvement in our operating performance.”

Tracy McLauchlin, Chief Financial Officer, added, “Our strong balance sheet and free cash flow allow us to execute a balanced capital allocation strategy that includes reinvesting in our businesses, strategic acquisitions, and opportunistic share repurchases. During the quarter we repurchased 46,133 shares for $0.7 million on the open market and continue to opportunistically repurchase our stock at attractive levels. We also reinvested $13 million in the form of working capital during the quarter in support of our continued 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 first quarter of fiscal 2019, the Company repurchased 46,133 shares at an average price of $16.08 per share. The Company had 678,671 shares remaining under its stock repurchase authorization at December 31, 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 quarterly report on Form 10-Q for the fiscal quarter ended December 31, 2018, to be filed with the Securities and Exchange Commission (“SEC”) by February 5, 2019, and any amendments thereto.
