Rathbones Group (LSE:RAT) Could Be 21% Undervalued On Integration Synergy Hopes

New director appointment and completed integration reshape the story

Rathbones Group (LSE:RAT) has brought Michelle Sylvia Scrimgeour onto its board as a director, shortly after completing the Investec Wealth & Investment integration that management links to planned margin improvements.

Rathbones Group’s recent appointment and the completed Investec Wealth & Investment integration arrive after a year where the share price return is down 16.5% year to date, even though the 3 year total shareholder return is up 23.4%. This suggests recent momentum has faded while longer term holders have still seen gains.

Rathbones Group shares have fallen this year while analyst targets and intrinsic value models sit meaningfully higher. The next step is to see where fair value really clusters between that trading price and the spread of estimates.

Most Popular Narrative: 21% Undervalued

Rathbones Group last closed at £15.98 while the most followed narrative pegs fair value closer to £20.12, so the gap between price, analyst expectations and intrinsic value models is doing most of the heavy lifting in this story.

The completion of the Investec Wealth & Investment (IW&I) integration unlocks significant scale advantages and operational synergies, providing a tangible opportunity to improve operating margins. Management expects these efficiencies to result in a 28% margin by Q4 2026 (from 25.4%), with full synergy benefit (~£60m annualized) set to be realized by the end of 2025. The remaining upside (target 30%) is described as dependent on organic growth in AUM and advice revenues.

See why 6 investors see Rathbones Group as 21% undervalued.

Result: Fair Value of £20.12 (UNDERVALUED)

Still, margin pressure from lower fee products and the risk that integration synergies arrive slower than expected could quickly weaken the bullish narrative around Rathbones Group.

Another View: Rathbones Group Through The P/E Lens

While Rathbones Group screens as undervalued against an internal fair value of £27.52, its P/E of 13.6x tells a different story. That multiple sits above the UK Capital Markets industry at 12.1x and above peer averages at 10.4x, yet is close to a fair ratio of 13.8x. For investors weighing margin ambitions against richer peer comparisons, the question is whether this gap signals a cushion or a thin margin for error.
