The venue recorded a turnover of just over £13m for the previous 12 month period.
ACC, which includes the BT Convention Centre and Echo Arena, said that it had welcomed 655,032 people through its doors for events including the Liberal Democrat party conference, and congresses for the British Dental Association and NHS Confederation.
Bob Prattey, ACC’s chief executive, said: "To experience an increase in turnover in the current climate is extremely encouraging, not only for ACC Liverpool but for the entire city region which benefits from our visitors and the events which we stage to the tune of £100m each year."
The venue is also taking its PR function in-house with the appointment of Nicky Hunter as PR and communications manager. She was previously senior account manager at agency Paver Smith.
