On April 10, 2017, IES Holdings, Inc., a Delaware corporation (“IES” or the “Company”), entered into the Second Amended and Restated Credit and Security Agreement (the “Amended Credit Agreement”), by and among the Company, each of the other borrowers and guarantors named therein and Wells Fargo Bank, National Association.

Pursuant to the Amended Credit Agreement, the Company’s maximum revolver amount increased from $70 million to $100 million, and the maturity date of the revolving credit facility was extended from August 9, 2019 to August 9, 2021. The Amended Credit Agreement also modified the Company’s financial covenants by, among other items, implementing a new covenant that requires the Company to maintain a minimum EBITDA (as defined in the Amended Credit Agreement) that will be tested quarterly on a trailing twelve month basis; increasing the minimum liquidity requirement applicable to the Company from 12.5% to 30% of the maximum revolver amount; raising the Company’s required fixed charge coverage ratio (the “FCCR”) to 1.1:1.0 from 1.0:1.0; and requiring that the FCCR be tested quarterly regardless of the Company’s liquidity levels. In addition, the Amended Credit Agreement modified the amount available under the revolving credit facility by increasing the availability related to progress-billed receivables that may be included in the Company’s borrowing base from $25 million to $40 million, while reducing the credit on these receivables from 80% to 75%.

The Amended Credit Agreement also eliminated provisions related to the structured overadvance amount and early termination premium, increased the aggregate cap on Company investments in certain securities from $10 million to $20 million, and permitted the Company to invest up to $10 million of that amount in non-marketable securities, provided for the inclusion of certain real estate in the borrowing base, and allowed for a one time increase in restricted payments to permit the Company to make stock repurchases in connection with satisfaction of employee tax withholding obligations on performance-based phantom stock due to vest in 2018. The Amended Credit Agreement continues to contain other customary affirmative, negative and financial covenants as well as events of default.

The representations and warranties of the borrowers party to the Amended Credit Agreement were made only for purposes of that agreement and as of specific dates therein and were solely for the benefit of the lender party thereto. The Amended Credit Agreement is a contractual document that establishes and governs the legal relations among the parties thereto and is not intended to be a source of factual, business, or operational information about the Company or its subsidiaries. The representations and warranties made by the borrowers party to the Amended Credit Agreement may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors. Accordingly, investors and security holders should not rely on such representations and warranties as characterizations of the actual state of facts or circumstances.

The foregoing description of the Amended Credit Agreement does not purport to be complete and is qualified in its entirety by reference to the Amended Credit Agreement, which is attached hereto as Exhibit 10.1 and incorporated herein by reference.

Certain statements in this Current Report on Form 8-K may be deemed “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934, all of which are based upon various estimates and assumptions that the Company believes to be reasonable as of the date hereof.

These statements involve risks and uncertainties that could cause the Company’s actual future outcomes to differ materially from those set forth in such statements. Such risks and uncertainties include, but are not limited to, the ability of our controlling shareholder to take action not aligned with other shareholders; the possibility that certain tax benefits of our net operating losses may be restricted or reduced in a change in ownership; the potential recognition of valuation allowances on net deferred tax assets; the inability to carry out plans and strategies as expected, including our inability to identify and complete acquisitions that meet our investment criteria in furtherance of our corporate strategy; competition in the industries in which we operate, both from third parties and former employees, which could result in the loss of one or more customers or lead to lower margins on new projects; fluctuations in operating activity due to downturns in levels of construction, seasonality and differing regional economic conditions; and our ability to successfully manage projects, as well as other risk factors discussed in this document and in the Company’s annual report on Form 10-K for the year ended September 30, 2016. You should understand that such risk factors could cause future outcomes to differ materially from those experienced previously or those expressed in such forward-looking statements.
