The men were survivors of the Liberian-flagged Eternity C, one of two commercial vessels sunk within days of each other in the Red Sea in July.
The Houthis released a video of the attack on the ship at the time, saying they had "rescued" an unspecified number of the crew and taken them to a safe location.
The Philippines' foreign ministry said it had received word from Oman that the "nine Filipino seafarers of the ill-fated M/V Eternity C, held hostage by the Houthis in the Red Sea, will be released".
The statement, which credited the efforts of the Omani government, said the men would first be transferred from Yemen's rebel-held capital of Sanaa to Oman before returning home.
A foreign affairs spokesman declined to provide a timeline for the release or say if it was bound by any conditions.
The July sinkings of the Eternity C and Magic Seas broke a months-long lull in Houthi attacks on Red Sea shipping, which began after the start of the Gaza war in October 2023.
The attacks, which the Houthis say target Israel-linked shipping in solidarity with the Palestinians, have prompted many firms to avoid a route that normally carries about 12 percent of global trade.
Filipino sailors make up as much as 30 percent of the world's commercial shipping force.
The nearly $7 billion they sent home in 2023 accounted for about a fifth of remittances sent to the archipelago nation.
