Exhibit 99.1

CACI Announces $250 Million

Accelerated Share Repurchase Agreement

Reston, Va., [January 30, 2023] – CACI International Inc (NYSE: CACI), a leading provider of expertise and technology to government enterprise and mission customers, announced today that it has entered into an accelerated share repurchase agreement (ASR) to repurchase $250 million of common stock under its previously announced $750 million share repurchase authorization. This equates to approximately 845,000 shares at the closing price on January 27, 2023, representing approximately 3.6% of CACI’s outstanding common stock. On January 31, 2023, CACI will receive an initial delivery of approximately 675,000 shares, with the final number of shares to be repurchased under the ASR based on the average of the daily volume-weighted average prices of CACI common stock during the repurchase period, less a discount and subject to adjustments pursuant to the terms of the ASR agreement. The company anticipates that all repurchases under the ASR will be completed by the end of August 2023.

Given the execution of this repurchase agreement, CACI now expects fiscal year 2023 interest expense to be between $80 and $85 million and the diluted weighted average share count to be approximately 23.5 million. Given the timing of the ASR in our fiscal year, we are reiterating our prior adjusted net income and adjusted earnings per share guidance. We expect the additional interest expense to be contained within our current adjusted net income range, and the impact of additional interest on adjusted EPS to be offset by the lower diluted weighted average share count.
