2 Various statements in this announcement, including those that express a belief, expectation, or intention, as well as those that are not statements of historical fact, are forward-looking statements. 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. Forward-looking statements are generally accompanied by words such as “anticipate,” “believe,” “estimate,” “expect,” “intend,” “likely,” “may,” “objective,” “outlook,” “plan,” “project,” “possible,” “potential,” “should,” “unlikely” or other words that convey the uncertainty of future events or outcomes. The forward-looking statements in this announcement speak only as of the date of this announcement. 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 beyond our control. No forward-looking statement can be guaranteed, and actual results may differ materially from those projected. Forward-looking statements in this announcement 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.

5 ▪ T&D primarily consists of small to medium-sized projects, with some larger High Voltage Direct Current (HVDC) transmission projects. We execute routine maintenance work under long-term Master Service Agreements (MSAs). Strong, long- term drivers are expected to continue to increase T&D spending. ▪ The core markets we serve in C&I remain active, with multiple growth drivers and notable strength in data center and transportation opportunities. ▪ Reshoring of manufacturing continues to create opportunities in our markets, and we believe both MYR Group business segments are well positioned to benefit from this. ▪ AI is driving growth in data centers and power demand. Data centers have been an important and growing end market for our C&I segment for a long time, while new interconnections, substations and infrastructure upgrades to data centers present additional opportunities for our T&D segment. ▪ Strong balance sheet with $650M in availability under our $890M credit facility and debt to LTM EBITDA leverage of 0.63x. Management believes our strong balance sheet will enable us to meet our working capital needs, support organic growth, pursue acquisitions, and opportunistically repurchase shares.

21 Demonstrated Strong Long-Term Execution Reconciliation of Non-GAAP Measures Note: EBITDA is not recognized under GAAP and does not purport to be an alternative to net income as a measure of operating performance 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 basis. 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 depreciation schedules when comparing our measures to our peers’ measures. Free cash flow is not recognized under GAAP and does not purport to be an alternative to net income attributable to MYR Group Inc., cash flow from operations or the change in cash on the balance sheet. Management views free cash flow as a measure of operational performance, liquidity, and financial health.
