Projects such as this are comliated, and like most big projects, the announced timelines for completion and operation are a collection of best case assumptions. Financing. Contracts. Sale and purchase agreements. Approvals from necessary third parties. Approvals by government(s). Nothing different was to be expected for NFE, a project where many pieces have to come together. As a result, a timeline will be extended whenever one of the best cast assumptions fails to deliver. Golar is another case where expected timelines did not become reality and the company paid the price. NFE is rather different in that there is less risk to completion of a project with Mexico than there is with, say, Nigeria or Madagascar. Or even, one could argue, less risk than dealling with states of the northeastern US, leftist courts or Biden's woke minions.
As far as the big dividend, that was a surprise but my assumption was that it represented a promise to Apollo in return for them taking a major stake. The company never explained the basis for the big dividend. Today, I am about breakeven with NFE, counting the dividends and continue to hold for future income.
