The owner of Long Island City’s One Court Square — which Amazon was committed to calling home before its sudden about-face — is close to inking a deal with a replacement tenant, according to a new report.

Savanna, the company that owns the 52-story, 1.4 million-square-foot tower, is set to lease up to 500,000 square feet to health care company Centene Corporation, Crains New York reported.

Amazon left Savanna in the lurch in February when it abruptly reneged on a $3 billion deal to bring its HQ2 to Queens.

The e-tail giant was set to lease a bulk of the behemoth complex — 1 million square feet — following current longtime tenant Citigroup’s departure.

Last year, St. Louis-based Centene — which provides affordable health care plans and is the largest Medicaid-managed care provider in the nation — acquired health care company Fidelis in Queens for nearly $4 billion, prompting its soon-to-be deal with Savanna, according to Crains.

Centene could relocate Fidelis, which has been peddling health plans to New York state for nearly three decades, from its current space in Rego Park to One Court Square, a source told Crains.
