Diploma shares (LON:DPLM) experienced a significant surge this morning, climbing 2.55% following a double upgrade from a prominent analyst, that came with a hefty price target hike. The positive sentiment reflects growing confidence in the company's financial health and strategic direction.
The stock's upward move this morning is primarily attributed to RBC Capital analyst Andrew Brooke's revised outlook. Brooke upgraded Diploma from Underperform to Outperform, simultaneously increasing the price target from 4,500 GBp to 6,000 GBp.
This bullish stance is underpinned by the assessment that Diploma represents “one of the safest growth names” within its peer group, particularly given the perceived limited value opportunities elsewhere in the market. This endorsement has resonated strongly, contributing to the increased buying pressure observed in early trading. Year-to-date, the stock has already delivered a return of 26.21%, underscoring its robust performance.
This positive momentum builds upon a series of favorable developments for Diploma in recent months. Berenberg Bank, on September 11, raised its price target to GBX 6,350 from GBX 5,750, reiterating a Buy rating. This upgrade propelled the stock to a new 52-week high, reaching GBX 5,565 during that trading session.
Concurrently, Jefferies Financial Group adjusted its price target upward from GBX 4,500 to GBX 5,200, assigning a Hold rating, a more conservative view but still indicative of recognized growth potential. Earlier in the year, JPMorgan Chase & Co. also revised its price target, increasing it from GBX 4,370 to GBX 4,420 while maintaining a Neutral rating. These successive upgrades collectively paint a picture of increasing analyst confidence in Diploma's prospects.
The upward revisions in analyst expectations are supported by the company's strong financial performance. In its half-year results reported on May 20, 2025, Diploma showcased a 14% increase in revenue, reaching £728.5 million, and a 25% surge in adjusted operating profit to £156.9 million for the period ending March 31, 2025. This impressive performance led the company to upgrade its full-year guidance, primarily driven by robust organic revenue growth of 9%, the successful integration of acquisitions, and effective operational leverage.
Further solidifying this trend, Diploma announced a strong Q3 performance on July 17, 2025, prompting an upgrade to its full-year organic growth forecast from 8% to 10%. The company also strategically invested approximately £39 million in acquiring Haagensen A/S, enhancing its Seals capability in Denmark, and Alpha Laboratories, marking its entry into the UK In Vitro Diagnostics market. These strategic moves are expected to contribute to future growth and market expansion.
However, not all recent news has been unequivocally positive. On August 14, 2025, Diploma announced the resignation of its Chief Financial Officer, Chris Davies, due to personal behavior inconsistent with the company's leadership standards. While this news initially created some uncertainty, the swift appointment of Wilson Ng, the Group Financial Controller, as Acting CFO helped to mitigate concerns. The company has reiterated that its financial guidance remains unchanged, reassuring markets of its stability.
Looking ahead, Diploma's ability to sustain its organic growth momentum, successfully integrate its recent acquisitions, and navigate the CFO transition will be critical factors influencing its future performance. The analyst upgrades suggest a belief that the company is well-positioned to capitalize on its strengths and deliver continued growth. The stock's recent gap up reflects the market's positive reaction to these developments, suggesting a bullish outlook for Diploma PLC. The increased price targets set by analysts like those at RBC Capital provide a clear benchmark for potential future gains, contingent on the company's continued execution of its strategic objectives.
