Bulls say / Bears say
Diploma delivered 15% organic growth in the first nine months and raised FY26 guidance again, now targeting 14% organic growth, a 26.5% operating margin and about 42% operating-profit growth. Repeated upgrades suggest current trading is running ahead of earlier expectations. (Investegate)
The first-half results showed strong operating leverage and cash generation: adjusted operating profit rose 33%, the margin reached 24.5%, free cash flow was £110.7m and leverage was 0.8 times EBITDA. This gives Diploma financial flexibility to keep investing while maintaining attractive returns. (Diploma PLC, Investegate)
Diploma’s buy-and-build strategy is adding another growth engine: acquisitions announced so far are expected to add 6% to reported growth, while the completed CDM deal creates a US interconnect platform with exposure to defence. Management also reports a healthy pipeline and significant balance-sheet capacity for further deals. (Investegate)
Growth is uneven across the portfolio. Controls is benefiting from favourable conditions and double-digit growth, but Life Sciences remains in challenging markets, leaving the group more dependent on continued strength in its industrial and technical businesses. (Investegate)
Management has warned that margins are near the top end and should moderate next year, while interest costs have risen as acquisition activity increased. That could make future profit growth less powerful even if revenue remains healthy. (Barchart, The Lincolnian Online)
