The US Defence Department has completed a comprehensive re-evaluation of its US$10 billion JEDI cloud computing contract proposals and determined that Microsoft's submission still represents the best value for the government.
Despite the reaffirmed award, the result of a comprehensive re-evaluation by the US Department of Defence (DoD), the contract remains on hold after a judge in February granted Amazon's request to temporarily halt the deal from moving forward.
Amazon, which has argued the contract process reflected undue influence from President Donald Trump, said on Friday it would "not back down in the face of targeted political cronyism or illusory corrective actions, and we will continue pursuing a fair, objective, and impartial review."
The company called the Pentagon's "re-evaluation nothing more than an attempt to validate a flawed, biased, and politically corrupted decision" and said in the last review it "offered a lower cost by several tens of millions of dollars"
Amazon, which had been seen as a front-runner to win the contract, filed a lawsuit in November weeks after the contract was awarded to Microsoft. Trump has publicly derided Amazon head Jeff Bezos and repeatedly criticized the company.
Amazon closed down 2.2 per cent.
Microsoft said it appreciated "that after careful review, the DoD confirmed that we offered the right technology and the best value. We’re ready to get to work."
The Joint Enterprise Defense Infrastructure Cloud (JEDI) contract could reach as much as US$10 billion and is part of a broader digital modernisation of the Pentagon aimed at making it more technologically agile.
The Amazon lawsuit said the 2019 Pentagon decision was full of "egregious errors", which it suggested were a result of "improper pressure from Trump, who launched repeated public and behind-the-scenes attacks" to steer the contract away from Amazon to harm Bezos.
As well as deriding the Amazon head, Trump has accused the Washington Post newspaper, owned by Bezos, of unfair coverage.
Defense Secretary Mark Esper has rejected that there was bias and said the Pentagon made its choice fairly.
