Mr Hedges, originally from Exeter, was arrested at Dubai Airport as he tried to leave the country on May 5.
The court ruling in Abu Dhabi drew forceful condemnation from the United Kingdom, with Prime Minister Theresa May expressing her deep concern and disappointment and vowing to take the case to the highest levels.
Sulaiman Hamid Almazroui told a press conference in London on Friday that his government was considering the appeal and would respond in due course but he defended the process under which Matthew Hedges was convicted.
Mr Hunt said he has seen "absolutely no evidence" to support claims Mr Hedges was spying when he visited Dubai earlier this year, and he threatened "serious diplomatic consequences" if he is not freed.
The oil-rich Gulf state said yesterday that Hedges can still appeal the verdict or request "presidential clemency".
Matthew Hedges, 31, was seen for the first time in five months as he appeared in court on Wednesday, and said he had expressed suicidal thoughts because jail conditions have caused him severe anxiety and panic attacks. "We live in a risky neighbourhood and national security must be a top priority", said Almazroui, adding that everyone had the right to request a pardon.

"They were stepping on eggshells instead of taking a firm stance", she said.
Hedges' case is proving to be a test of the UK's global power.
He said he had held a contructive conversation on Thursday with his UAE counterpart Sheikh Abdullah Bin Zayed. "This is something I feel they failed to do throughout really", she said.
The UAE statement said Hedges was convicted after "compelling and powerful evidence was presented in court".
Hedges was arrested after an Emirati man reported him to police for "asking sensitive questions about some sensitive departments" and "seeking to gather classified information on the UAE", The Guardian reported.
She said: "He has assured me that he and his team are doing everything in their power to get Matt free and return him home to me".
"The British government must take a stand now for Matthew, one of their citizens", Tejada told the Guardian.
A family representative said Mr Hedges was held in solitary confinement for over five and a half months, during which his "mental and physical health seriously deteriorated".
