Methodology WHAT IS THE UK GENDER PAY GAP REPORT? The Gender Pay Gap Reporting (GPGR) legislation requires employers in the UK with 250 or more employees to publish calculations every year showing the pay gap between their employees who identify as men and women. WHAT DOES THE UK GENDER PAY GAP MEASURE? The UK Gender Pay Gap is a basic calculation of the percentage di昀昀erence between average hourly earnings for men and women, regardless of the work they do. Earnings include base pay, allowances and any other bonus and incentive pay paid 6 April 2022 - 5 April 2023. The Gender Bonus Gap is the percentage di昀昀erence in all incentive pay received by men and women in the 12 months up to April 2023, including bonuses and sales commission payments. WHAT ISN’T MEASURED? The pay gap is not a measurement of equal pay. It is one basic measure across all jobs, not a measure of the di昀昀erences in pay between men and women within the same job type. 05

Understanding the Data Mimecast provides di昀昀erential Compensation Packages for those in Senior Roles by o昀昀ering competitive Bonus and Equity packages that encourage strong performance and employee retention amongst critical leadership positions. Roles that require strong technical expertise also attract higher pay in order to attract the best talent in an ever-growing competitive landscape. With a higher proportion of men than women occupying Senior positions and Technical Roles at Mimecast, our opportunity to reduce our gender pay gaps lies heavily in the hiring and retention of women in these areas across the business. Additionally, the gender balance in the Go-To-Market Function has been predominantly male, further contributing to the di昀昀erence in earning potential by gender. We are working closer with our female employees to support their progress and help them improve their career longevity in sales roles. 08

Further, for Director-level and above roles, Mimecast leverages a Future Builders Program where members of our Employee Resource Groups participate in the interview process.

Mimecast UK Gender Pay Gap Report 2023 Conclusion Looking ahead... “We have seen real progress this year in the promotion of women into senior positions in Mimecast and areas where we have closed the pay gap. We have also seen DEI become front and centre of how we hire, promote and retain our employees as leaders and managers truly see the value of having a diverse workforce. However, there is always more to do to close gender gaps, promote women in Mimecast and celebrate the richness of diversity. The UK Leadership Team has seen a change in Leadership and even more emphasis placed on equity in managing employees. This team Pippa Gray is accountable and plays an active role in making Mimecast a place where Senior HR Director women can thrive and build an inclusive future for all, leaning into our MIMECAST recruitment, talent and performance programmes to hire, promote and reward women. I’m encouraged by the participation of our Mimecasters to actively lean into conversations about gender, equity and biases and to be vocal in ensuring fairness of policy and process. I continue to learn so much from them, which helps me ensure I can better support our employees and create meaningful change toward a more diverse and just workplace. “ "To align with UK government reporting requirements, data in this report refers to the traditional sex categories of male and female. Mimecast respects that gender is on a non-binary spectrum and reporting in this manner should not be interpreted as our position on this. I con昀椀rm that our data has been calculated according to the requirements of The Equality Act 2010 (Gender Pay Gap Information) Regulations 2017.” 13
