Oct 25 (Reuters) - Australia's Ampol Ltd (ALD.AX) forecast record full-year earnings and posted a threefold jump in quarterly profit on Tuesday, as strong demand for refined products pushed up refining margins at the country's biggest fuel supplier.
Its shares, however, sank more than 9%, as its third-quarter net profit missed Jefferies' estimate, amid the company warning of further market volatility.
"The market volatility experienced year to date is expected to continue in the period ahead."
The company's quarterly net profit on a replacement cost basis, which excludes the impact of inventory and foreign exchange changes, was A$102.5 million ($64.70 million), significantly missing Jefferies' estimate of A$199 million.
Refining margin at the Queensland refinery was $15.46 per barrel, significantly higher than $6.76 per barrel a year ago, but below the $32.96 a barrel in the prior quarter.
