PHI Inc., a Lafayette-based helicopter company, reported its 2015 profit slumped to $26.9 million, or $1.72 per share, compared with $32.7 million, or $2.08 per share in 2014.

The profit at the company’s oil and gas segment fell to $41.3 million, less than half the $100.6 million in 2014. The lower profits were primarily the result of fewer aircraft under contract and fewer flight hours.

PHI’s air medical segment saw its profit climb to $55.8 million, compared with $46.8 million a year ago.
