Building Leadership Capability
For Halma

STOIX has made 32 appointments across Halma’s group functions and operating companies, from building M&A and integration teams to appointing CFOs, Presidents, General Managers and Chief Commercial Officers globally.

The relationship has grown through personal referrals and recommendations within the group, earned through the quality of delivery. Leaders who first encountered Rory McDermott and STOIX as candidates returned when they needed to build their own teams.

Two of those relationships, with Hannah Younger and Lionel Aillerie, illustrate the approach behind five appointments in Healthcare M&A, integration and divestments.

The Brief

Hannah Younger needed to build out the Healthcare sector’s M&A capability. Three different appointments would strengthen deal execution, origination and strategy through market insight. Each called for its own expertise, with the combined team helping her broaden the sector’s approach to acquisition-led growth. 

Lionel Aillerie was establishing the team and processes supporting integration and divestments. He needed additional capacity and people who could understand the practical work of bringing businesses into the group. His remit also required flexibility across integration and divestment projects. 

The Challenge

Understanding Halma’s operating model was central to both assignments. Technical experience had to be considered alongside how someone would work within the business, build relationships and fit the leader’s team. Lionel described the importance of recognising who would feel comfortable in that environment and who might struggle, even with a strong CV. 

For his senior appointment, the combination was particularly demanding: accounting depth, M&A exposure, curiosity and a genuine interest in the work. Finding people with both the relevant experience and the motivation to apply it made the available pool narrow. 

Our Solution

Both relationships began with Rory working with Hannah and Lionel as candidates. Their experience of the process informed their decision to return to STOIX when they needed to hire. 

Hannah valued the empathy, accessibility and communication she had experienced herself. She wanted prospective team members to receive the same thoughtful treatment. STOIX developed a detailed understanding of each role’s profile and intended contribution, then used its M&A knowledge and relationships across the UK, Europe and US to build relevant shortlists. 

For Lionel, understanding the culture and his way of working helped the team assess candidates beyond their experience on paper. Video introductions added another perspective. He described reconsidering people whose CVs alone might not have secured an interview, because the videos revealed more of the person behind the application. 

When the initial shortlist did not produce an appointment, STOIX returned to the search. The team ultimately identified someone with experience of both integration and divestments, allowing Lionel to deploy that capability across either type of project. He subsequently returned to STOIX for a more junior appointment.

The Result

Five appointments strengthening Healthcare M&A, integration and divestments

STOIX helped Hannah make three appointments and Lionel make two, strengthening their teams’ expertise and capacity. Hannah reports that all three of her hires are thriving. Together, they have increased market coverage, generated more off-market acquisition prospects and helped develop a more structured approach to M&A, including standard ways of working and continuous improvement. At the time of the interview, Lionel’s senior hire had made a positive early impression, was building relationships across the business and had begun work on a divestment. Lionel highlighted the quality of their questions and the strong working relationship they were developing. A subsequent junior appointment added further capacity. Both relationships began with a candidate experience that gave Hannah and Lionel the confidence to entrust STOIX with building their own teams. Those five appointments form part of the wider 32-hire relationship across Halma.

“STOIX have been critical to accelerating our ability to grow through M&A. We’ve been able to increase our coverage, generate more off market deal prospects and become a bit more sophisticated in terms of how we approach M&A.”

“Rory really understands the culture, what is it that is going to make someone potentially successful and what is it that on the other hand could make someone look right on paper but that raises a question about their fit with the company. ”
