Diploma stock closed at 7,485 pence on the London Stock Exchange on September 21, 2026, up 2.89 percent from the previous close. The move followed Ad-hoc-News coverage dated September 22, 2026, of JPMorgan's upgrade and revised price target.

JPMorgan raises target 43.2 percent

According to Ad-hoc-News on September 22, 2026, JPMorgan raised its Diploma target to 8,250 pence from 5,760 pence and upgraded the shares to Overweight from Neutral. The 2,490 pence increase equals 43.2 percent, while the revised target stands 765 pence above the September 21 closing price.

The upgraded view gives the stock a defined valuation reference, but the target remains a broker estimate rather than a company forecast. Diploma supplies specialist controls, seals and life sciences equipment, with the business spread across industrial, medical and aerospace-related applications.

Business mix spans three divisions

A September 23, 2026 business overview lists revenue of GBP 940 million from Controls, GBP 454 million from Seals and GBP 253 million from Life Sciences. The same overview puts Diploma's market capitalization at GBP 10.2 billion, making the Controls division the largest of the three reported revenue streams.

The division figures add to GBP 1.647 billion and show why the mix matters for valuation: Controls represents about 57.1 percent of the stated divisional revenue, while Life Sciences represents about 15.4 percent. These figures are divisional context dated September 23, 2026, not a substitute for a consolidated reporting-period result.
