Metso Outotec is committed to building a Tier-1 company with strong focus on growth and profitability. In the future, we continue to implement our four top priorities that are common for all our businesses and address the interests of our stakeholders: financial performance, customer success, sustainability and performance culture. As the integration of Metso and Outotec has now been completed, our focus has shifted more towards growth and customer success.
Our target in the integration of Metso and Outotec was to realize EUR 120 million of annual pre-tax run-rate cost synergies by the end of 2021 and EUR 150 million of annual revenue run-rate synergies by the end of 2022. The synergy results were achieved by the end of 2021, with EUR 142 million of cost synergies and EUR 110 million of revenue already recognized in sales in 2021 and EUR 115 million in order backlog to be recognized in 2022. Going forward, our focus is on continually improving financial performance across all our businesses.
When it comes to customer success, it is at the core of our strategy. We want to support our customers to succeed and succeed together with them. Our aim is to better leverage our strong aftermarket presence globally. We have already implemented a key account management model to provide excellent service for our global and market area key customers, as well as improved our distribution management model in the Aggregates segment.
