Chairman Yasir Al-Rumayyan and minority owner Jamie Reuben were among the PIF delegation that flew into the North East for the annual gathering at Matfen Hall in Northumberland, which covered on-pitch performance, infrastructure plans, and summer recruitment strategy.
Howe gave a presentation to the group on Thursday and came away encouraged by the level of backing directed his way despite a difficult season that has left Newcastle United 14th in the Premier League.
Speaking to BBC Sport ahead of the home fixture against Brighton, Howe said the ownership's ambition remained firm.
"The desire is unchanged. It's to try and get to the top of the Premier League, to try and consistently win as many trophies as possible. I don't think that will change while the PIF are our owners."
An announcement is expected imminently on a new state-of-the-art training ground, with PIF understood to have approved capital investment of up to £100 million on the project. CEO David Hopkinson described the initiative as essential to matching world-class ambition with world-class infrastructure.
The future of St James' Park is also under active consideration. The club are weighing whether to expand the existing stadium or build a new ground entirely, with the decision framed around closing a significant revenue gap on the league's highest-earning clubs.
"There are very exciting times ahead for the club, regardless of what happens short-term. The long-term vision is clearly there," Howe said.
He acknowledged the conversations with ownership were challenging in parts but said the support for his position was genuine.
"I was pleased by the level of support given to me, but of course still understanding how football works and knowing we need to get results."
Newcastle's stated ambition is to be consistently challenging for the Premier League title and trophies by 2030. A season spent in the bottom half of the table has made that target harder to reach, but the ownership have shown no signs of scaling back their vision.
