RALEIGH, N.C., Oct. 19, 2026 /PRNewswire/ — Cardinal Infrastructure Group, Inc., (NASDAQ: CDNL) (“Cardinal” or the “Company”) today announced that it has entered into an amendment to its previously announced agreement to acquire Hughes Brothers Construction Inc. (“Hughes Brothers”), a leading Central Florida heavy civil and site development contractor.

The amended agreement maintains the $357.5 million purchase price and changes the consideration to 60% cash and 40% Cardinal Class A common stock, from 50% of each previously. Hughes Brothers’ owners will receive approximately $214.5 million in cash and 5,255,420 shares of Cardinal Class A common stock, based on an issue price of $27.21 per share.

The amendment also revises the earnout so that the sellers will be eligible to receive up to a maximum of $162.5 million based on Hughes Brothers adjusted EBITDA for the 12 months ending June 30, 2027, payable 60% in cash and 40% in stock. At the maximum, the earnout would include up to approximately 2,388,827 additional shares at the issue price of $27.21 per share.

Cardinal expects the acquisition to be immediately accretive to adjusted EBITDA per share. Hughes Brothers generated an adjusted EBITDA margin¹ of 25% on revenue of $220 million for the 12 months ended June 30, 2026, and its current backlog of approximately $350 million provides visibility into future revenue and profitability. The acquisition establishes a scaled platform in the fast-growing Central Florida market and supports Cardinal’s strategy to build the Southeast’s premier site development platform.

The transaction is still expected to close in the fourth quarter of 2026, subject to regulatory approvals and customary closing conditions. The cash consideration will be funded through cash on hand and borrowings under Cardinal’s existing credit facility.

Important Information for Investors and Stockholders

Non-GAAP Measures

This press release includes a discussion of Adjusted EBITDA and Adjusted EBITDA margin, which are “non-GAAP” financial measures as defined in Regulation G under the Securities Exchange Act of 1934. Cardinal and Hughes Brothers report financial results in accordance with U.S. generally accepted accounting principles (“GAAP”) but believe that certain non-GAAP financial measures provide useful supplemental information to investors regarding the underlying business trends and performance of their respective ongoing operations and is useful for period-over-period comparisons of those operations. Non-GAAP measures should be used in addition to, and not in lieu of, results prepared in conformity with GAAP.

The following table provides a reconciliation of Hughes Brothers net income to EBITDA, and adjusted EBITDA to adjusted EBITDA margin for the 12 months ended June 30, 2026:

Cardinal is not able to provide the most directly comparable GAAP financial measure, or a quantitative reconciliation thereto, for the forward-looking guidance of estimated Adjusted EBITDA Margin without unreasonable effort due to the inherent uncertainty and difficulty in predicting the timing and amount of certain items, including but not limited to amortization of intangible assets and depreciation, which may be significant and difficult to project with a reasonable degree of accuracy, as the allocation of purchase price to intangible assets and property and equipment has not yet been performed. Because these adjustments are inherently variable and uncertain and depend on various factors that are beyond Cardinal’s control, Cardinal is also unable to predict their probable significance. The variability of these items could have an unpredictable, and potentially significant, impact on Cardinal’s future GAAP financial results.
