Exhibit 4.23    Edwards Group plcs Executive Annual Bonus Scheme 2012  CEO & CFO  Scheme Objective  The Companys Executive Annual Bonus Scheme FY2012 is designed to reward a high performance culture by providing a clear link between the Companys performance and pay and by aligning your bonus payment to the Companys overall business achievements.  Bonus Structure:  ·80% based on Company Financial performance, 20% based on functional performance ·100% of bonus paid annually ·Introduction of an EBITDA Margin threshold to trigger the functional performance and annual payment element  This year, 80% of your bonus opportunity will be based on the Companys financial performance. The remaining 20% will be based on functional performance assessed by reference to the functional performance targets you have agreed with Remco and which are aligned to the Company corporate scorecard.  Your annual bonus opportunity is as follows:  Threshold Bonus Opportunity (% of base salary)

35
%On Target Bonus Opportunity (% of base salary)

70
%Maximum Bonus Opportunity (% of base salary)

91
%  The bonus scheme will run from 1 January 2012 to 31 December 2012.  Financial Element  The financial element will account for 80% of the bonus opportunity and will be based on the followingthree financial measures:  ·The Companys EBITDA ·The Companys EBITDA Margin ·The Companys Operating Cash Flow  Each measure is discreet and equally weighted, based upon the Companys financial priorities, and set out in the table below:  1

£115.0m  At the end of the year, a bonus payment will be made in respect of each financial measure if the target for that measure has been met. Payments will normally be made in the second month after the close of the year (due to confidentiality and financial reporting requirements)  ·At the end of Q4, if the full year performance targets are met, then you will receive 80% of your annual bonus opportunity. This payment would normally be made in March 2013. ·There is also the potential to receive higher bonus payments (up to a maximum of 30% of your target bonus) by over-achieving against the targets. The maximum level of stretch bonus payment would be triggered by achieving the Maximum target detailed in the table above.  Incremental bonus would be paid on a straight line basis for performance between the target and the maximum target. ·If none of the financial targets have been met through the year but the EBITDA Margin threshold target has been met this would then trigger a cumulative payment of 50% of the annual payment including the functional performance element.  Functional Performance Element  At the end of the year, if the EBITDA Margin target is met, this will trigger a 100% payment pot for the functional performance element.  It is your responsibility to set and agree your functional performance targets with the Remco which are aligned to the Company corporate scorecard. At the end of the year, you will be given a Functional Performance Score (based on performance against your agreed functional performance targets) which will be used to determine any payment within the final 20% of the bonus opportunity.  The Functional Performance Score will be translated into a factor to be used in your bonus calculation as per the table to the right.  Achievement of the threshold target for EBITDA margin will trigger a 50% payment pot for the functional performance element.  Performance between the threshold level and the target level EBITDA margin will be calculated on a straight line basis to calculate the payment pot.  The fifth payment is capped at a 100% payment pot maximum and an assessment of the relevant functional performance score may adjust this upwards or downwards.  Functional   Performance   Score

The individual fifth payment will be calculated by multiplying the Functional Performance Factor, the 20% weighting and the On Target Bonus Opportunity percentage, as per the example below (which assumes a Functional Performance Score of 125):  Functional    Performance    Factor  =1.08

15.12%  Any payment related to the functional performance element will normally be made in March 2013.  If the threshold EBITDA Margin target is not met the Board may at its discretion authorise payment of the functional performance element.  How does the scheme work?  Payments related to the financial element will only be triggered in respect of each individual financial measure if the target for each such individual financial measure is achieved at the end of the year. No payments will be made for measures below target. Subject to the achievement of these targets, you will receive payment on or around March 2013.  Payment related to the functional performance element can only be triggered if at the end of the year, the EBITDA Margin performance metric exceeds the Threshold level.  The table below sets out an illustration of your on target bonus opportunity - as a percentage of base salary - and demonstrates how the scheme will operate.  Metric

20.0%  At the end of each quarter, a bonus payment will be made in respect of each financial measure if the target for that measure has been met. Payments will normally be made in the second month after the close of the quarter (due to confidentiality and financial reporting requirements)  ·If Q1 performance targets are met, you will receive 15% of your annual target bonus opportunity in May 2012. ·At the end of Q2, if the first 6 months performance targets are met, you will receive an additional 15% of your annual target bonus opportunity in August 2012 ·At the end of Q3, if the first 9 months performance targets are met, you will receive a further 15% of your annual target bonus opportunity in November 2012 ·Throughout the financial year, there is also the potential to receive higher bonus payments (up to a maximum of 30% of your target bonus) by over-achieving against the targets. The maximum level of stretch bonus payment would be triggered by achieving the Maximum target detailed in the table above.  Incremental bonus would be paid on a straight line basis for performance between the target and the maximum target. ·At the end of Q4, if full year performance targets are met, then a true up will be made for the year  which essentially means that any quarters where the targets were missed will be paid at the appropriate full year achievement level.  This payment would normally be made in March 2013. ·If none of the financial targets have been met through the year but the EBITDA Margin threshold target has been met this would then trigger a payment of 50% of the annualised elements of the bonus  the functional performance element (normally worth a potential 20%) and the non-quarterly financial performance element (also normally worth a potential 20%)  7


Functional Performance Element  At the end of the year, if the EBITDA Margin target is met, this will trigger a 100% payment pot for the functional performance element.  It is your responsibility to set and agree your functional performance targets with the CEO which are aligned to the Company corporate scorecard. At the end of the year, you will be given a Functional Performance Score (based on performance against your agreed functional performance targets) which will be used to determine any payment within the final 20% of the bonus opportunity.  The Functional Performance Score will be translated into a factor to be used in your bonus calculation as per the table to the right.  Achievement of the threshold target for EBITDA margin will trigger a 50% payment pot for the functional performance element.  Performance between the threshold level and the target level EBITDA margin will be calculated on a straight line basis to calculate the payment pot.
