The losses were an improvement on 2023, with Turnberry recording a loss of £1.7 million that year and Trump International a loss of £1.4 million.
In his report on Turnberry, Eric Trump, 41, said the revenue increase was driven by luxury travel groups and leisure visitors to the coastal hotel and spa, while the golf business, where rates can top £1000 for a round, “outperformed”.
He said: “Ownership remains steadfastly committed to their vision for the property and confidently foresees a positive fiscal improvement as the investment activities flow through in the medium and longer term.”
Trump visited the Aberdeenshire site in July to open a new course there.
The first Trump Aberdeenshire course opened in 2012 following a long and often controversial planning process with local opposition centred around the impact on the landscape.
Trump bought Turnberry in 2014 from the Dubai-based Leisurecorp in a deal which was reported to be worth around $60 million at the time.
The Open was last held on the Ailsa course in 2009 with Stewart Cink narrowly holding off a challenge from Tom Watson.
A petition against Turnberry hosting The Open in the future attracted more than 56,000 signatures in July.

Despite having been launched in May, it picked up a head of steam when Trump visited Scotland.
R&A officials have met with Eric to discuss the major returning to Turnberry.
R&A chief executive Mark Darbon has said there are “big logistical issues” with the tournament being held at the venue with the number of spectators having spiked considerably in recent years.
Sarah Malone, the executive vice president at Trump International Scotland, said: “Trump Turnberry and Trump International Scotland saw substantial revenue growth across all income streams in 2024 and attained their highest ever annual turnovers.
“Both businesses have also benefited from major capital investments to further expand and enhance their top-world-ranked golf courses and leisure facilities.”
