US & Canada acquisition timeline
Three waves of M&A built today's North American footprint. The first set is now deeply group-embedded; the most recent set is where founder-transition risk — and opportunity — lives.
US market profile
The US is the centre of gravity.
Where £800m+ of group revenue livesNorth America accounts for 53% of Diploma's revenue — the single largest geography by some distance. Eight US-headquartered operating companies sit inside the group, with the biggest concentrations in Controls (Windy City Wire alone is 20% of group) and Seals (the two Hercules entities plus VSP).
Diploma's CHRO Donna Catley has publicly signalled that the US is one of the targeted growth markets for talent investment, and the group's first-ever graduate programme launched in October 2025 across the US and UK.
Why this matters for hiring
The decentralised model means MDs are pivotal. Diploma has been refreshing the MD cohort — external hires plus internal promotions — and rebuilding the layers underneath (business CFOs, HR leaders, sales leadership) to support succession.

02 · Hiring Philosophy & Our MandateWhat Diploma is hiring for — and what we're helping solve.
How Diploma's talent thesis shapes our brief for VSP Technologies and the US bench.
Diploma's talent thesis (CHRO commentary)
MDs are the pivot.
The decentralised model puts the MD at the centre — strategy delivery, agility, customer focus all flow from the seat. Group has reset the MD remuneration framework specifically to attract and retain top operating leaders.
Refreshing the cohort.
External hires combined with internal promotions to build succession. The group has built up the layers underneath the MDs — business CFOs, HR leaders, sales leadership — precisely so the next President is already in seat.
US is named as a target market.
Targeted analysis of key markets — the US explicitly — for talent-pool access aligned with growth strategy. First-ever graduate programme launched Oct 2025 across US and UK.
DE&I targets are public.
40% women in Top 150 by FY30 (currently 32%, up from 20% in FY19). Ethnicity target for senior leadership by FY27. 50% of Executive Team have a diverse characteristic.
The succession lens
Why FDs and CDs matter most.
Identified by Diploma as the two roles most likely to step up to PresidentDiploma's working hypothesis — reflected in the structure of the group's recent leadership refresh — is that Finance Directors and Commercial Directors are the two seats most likely to feed the future President bench. Some current Presidents are previous owners who came with the acquisitions; others are newly appointed under Diploma. The succession picture depends on knowing which is which and what the internal & external bench looks like under each.
2009–2018 saw no US / Canada operating-company acquisitions (group focus was on European specialist distribution bolt-ons). 2022 was similarly a UK / European year. The three buckets above therefore map cleanly to the US / Canada M&A waves.
Our mandate
What Solutions Driven is delivering
Scope of the Diploma engagement- Corporate portrait — Diploma at group, sector and division level. Established baseline above.
- Operating-company deep-dives — identify the President, FD and CD at each US business, cross-reference tenure with the acquisition date, flag previous-owner vs newly-appointed.
- External commercial & finance leadership bench — passive bench within commutable radius of each Diploma site; full named pool surfaces in later phases.
- Future business-leadership identification — the President-ready bench at the $30–$200M revenue band that fits Diploma's MD model.
- M&A churn signals — events likely to release passive talent (Flexitallic/Michelin close, Garlock strike, etc.).

VSP within the Diploma group
Where it sits in NA SealsVSP is one of three sister businesses in the NA Seals sector under CEO Neil Yazdani. Hercules OEM (Minneapolis) and Hercules Aftermarket (Clearwater FL + Louisville KY) are the other two.
Headcount trajectory
+15.7% YoY · most aggressive of NA Seals21 net adds over the last twelve months — the strongest growth signal in the NA Seals sector. The controller seat just rotated (Fontaine, Oct 2025) so the FD search window is 12-24 months out, not immediate.

Compensation benchmarks — Richmond VA + national mfg
Base salary ranges by role & location
BLS OEWS-anchored · refreshed May 2026 · 14 rolesTypical bonus & LTI overlay
Industrial mfg / distribution normsLTI patterns differ by parent
PE-backed competitors (Lamons / Flexitallic legacy) use MIP or phantom-equity pools of 0.25–1.0%. Public-co subsidiaries like Diploma and Enpro / Garlock use RSUs or cash-settled LTI — typically smaller at sub-co leader level. That means VSP cannot win FD / CD candidates on equity upside alone; the comp pitch has to lean on parent stability, FTSE governance and cross-Diploma mobility instead.

Lateral / sideways mover pool by site
Candidates already sitting at FD or CD level in a peer business — available to move sideways into the equivalent VSP seat without a promotion event. Naturally a smaller pool than step-up.

SStrengths · The CVP

"Come for the autonomy, stay for the stability."
VSP is a strong proposition for ambitious mid-tier FD/CD candidates who want a top-table seat in a stable, founder-led, FTSE-backed business after Tier-1 churn or PE fatigue. While the Tier-1 rivals (Garlock, John Crane, Lamons, Flexitallic) carry larger comp ceilings, VSP's competitive edge lies elsewhere: positioning, succession storytelling (the Tyler Ragsdale internal-rise narrative), and the cross-Diploma career-portability story are the levers that win this market.
The Michelin / Flexitallic close (Apr 2026) opens a 6-12 month window of disrupted Houston / Webster talent — this is the most actionable signal to lean into right now.
