Quarterly Financial Information – Unaudited

In the opinion of management, the following unaudited quarterly data for the fiscal years ended September 30, 2018 and October 1, 2017 reflect all adjustments necessary for a fair statement of the results of operations.

As a result of the TCJA, we reduced our deferred tax liabilities and recorded a one-time deferred tax benefit of approximately $14.7 million in the first quarter of fiscal 2018. In the third quarter of fiscal 2018, we recognized losses of $3.4 million related to the divestiture of our non-core utility field services operations and other non-core assets. We settled a claim related to a fixed-price construction project completed in fiscal 2014 and recognized a reduction in revenue of $10.6 million and a related loss in operating income of $12.5 million in the fourth quarter of fiscal 2018.
