Key Recommendation Rationale – Sell at GBX 1,340.00

• Resistance near Current levels: ABDP’s stock price crossed the Support (S1) which was stated in the previous report on 26 September 2025 therefore, there could be a possibility that the stock might consolidate or decline from the current levels, considering overstretched valuation. Considering the market conditions and the price action, it is prudent to exit from the stock.

• Organic Revenue Growth Stagnation: Revenue grew only 3% in FY2025, falling short of the 10% target, as a strong H1 was offset by a H2 decline. This volatility, driven by timing-dependent orders in Simulation, indicates susceptibility to customer capital expenditure delays and undermines predictable growth.

• Margin Expansion Driven by Non-Recurring Mix, Not Sustainable Efficiency: The 210bps margin improvement to 20.3% was partly fueled by a favorable revenue mix not expected to recur. This suggests core, sustainable operational improvements alone may not support further near-term margin expansion, raising questions about the quality of this performance.

Conclusion

Revenue growth stagnated at 3%, far below the 10% target, due to volatile, timing-dependent orders in H2. The significant margin improvement to 20.3% was partially driven by a non-recurring favorable revenue mix, raising concerns about the sustainability of core operational efficiency gains and the predictability of future profitable growth.

For conducting the valuation, the following peers have been considered: Journeo PLC (LSE: JNEO), Transense Technologies PLC (LSE: TRT), etc.

Given its current trading levels, the recent strategic investments and partnerships, relative valuation, and associated risks, it is prudent to exit the stock at the current levels. Hence, a ‘Sell’ recommendation is given on the stock at the Current Market Price of GBX 1,340.00 as of 09 December 2025, 08:04 AM, GMT.
