The forward - looking statements may include projections and estimates concerning the timing and success of specific projects and our future production, revenue, income, capital spending, segment improvements and investments.

The forward - looking statements in this communication speak only as of the date of this communication; we disclaim any obligation to update these statements (unless required by securities laws), and we caution you not to rely on them unduly. We have based these forward - looking statements on our current expectations and assumptions about future events. While our management considers these expectations and assumptions to be reasonable, they are inherently subject to significant business, economic, competitive, regulatory and other risks, contingencies and uncertainties, most of which are difficult to predict and many of which are bey ond our control. No forward - looking statement can be guaranteed and actual results may differ materially from those projected. Forward - looking statements in this communication should be evaluated together with the many uncertainties that affect MYR Group’s business, particularly those mentioned in the risk factors and cautionary statements in Item 1A of MYR Group’s most recent Annual Report on Form 10 - K, and in any risk factors or cautionary statements contained in MYR Group’s Quarterly Reports on Form 10 - Q or Current Reports on Form 8 - K. │ Page 2 Investor Presentation │ AUGUST │ ©2018 MYR GROUP INC.

EBITDA RECONCILIATION │ Page 21 Investor Presentation │ AUGUST │ ©2018 MYR GROUP INC. Company Overview │ Strategy │ Market Overview │ Financial Performance │ Investment Outlook │ Appendix Note: LTM diluted weighted average shares outstanding were determined by adding the average shares reported for the last four quart ers and dividing by four. EBITDA is not recognized under GAAP and does not purport to be an alternative to net income as a measure of operating perform anc e or to net cash flows provided by operating activities as a measure of liquidity. EBITDA is a component of the debt to EBITDA covenant that we must report to our bank on a quarterly bas is. In addition, management considers EBITDA a useful measure because it eliminates differences which are caused by different capital structures as well as different tax rates and depreci ati on schedules when comparing our measures to our peers’ measures.
