F1's overall income rose from $1827m in 2018 to $2022m last year, and after posting losses of $37m in 2017 and $68m in 2018 the group logged a profit of $17m.

The increased revenue meant that the recent fall in the income paid to the 10 teams has been reversed at a time when discussions over a new Concorde Agreement for 2021 and beyond are still ongoing.

The teams earned $966m between them in 2016, which dropped to $919m in 2017 and then $913m in 2018. In 2019 they shared a pot of $1012m.

F1's improved performance was led by a boost in primary revenue, derived from broadcast fees (38%), sponsorship (15%) and race hosting fees (30%), although the latter element actually performed worse in 2019.

Liberty explained F1's performance in its main areas of business thus: "Broadcast revenue increased in the fourth quarter and full year due to contractual rate increases, partially offset by the impact of weaker foreign exchange rates.

"Advertising and sponsorship revenue was relatively flat in the fourth quarter, and advertising and sponsorship revenue grew in the full year due to revenue from new sponsorship agreements.

"Growth in these revenue streams was partially offset by a decline in race promotion revenue in both the fourth quarter and full year.

"The fourth quarter decline in race promotion revenue was primarily due to the renewal terms of one contract, and the full year decline was driven by the impact of renewal terms of two contracts and weaker prevailing foreign exchange rates."

Liberty said that income grew in its non-primary streams, including digital media.

It noted: "Other F1 revenue increased in the fourth quarter and full year 2019 driven by increases in digital media revenue, higher Paddock Club attendance, increased revenue from other event-based activities and higher sales of equipment, parts and maintenance to F2 and F3 teams."

Liberty also acknowledged that F1's costs rose in 2019. The payments to teams, which are considered the main cost, are related to the overall income levels and "the associated impact on variable elements of team payments."

Other costs rose "due to various technical initiatives, the continued further development and delivery of digital and social media products and platforms, increased costs related to the sale of equipment, parts, maintenance and other services provided to F2 and F3 teams and higher FIA fees."

F1 CEO Chase Carey was bullish regarding future prospects for the company.

"F1 continues to benefit from the investments made in the business over the past few years," he said. "We see this in the strong financial results, viewership, attendance and engagement. 2020 marks the 70th anniversary of the sport, which will provide further momentum."

Liberty president and CEO Greg Maffei noted: "F1 produced exceptional financial results, added viewers and grew race attendance."

Alongside the financial numbers Liberty noted that in 2019 aggregate race attendance rose by 2% to 4.2m, social media followers rose 33% to 24.9m, and cumulative TV viewers were up 9% to 1.9bn.
