Why is Ab Dynamics stock sliding today?

Ab Dynamics stock fell 5.1% to trade at 754.5p after the company published its full-year FY 2026 results this morning, revealing a broad-based deterioration in financial performance driven by challenging conditions across the global automotive industry.

Revenue declined 12% to £91.6 million from £104.2 million the prior year, while adjusted operating profit fell 18% to £18.3 million and adjusted diluted EPS dropped 21% to 60.3 pence — with statutory operating profit down a steeper 38%.

The sharpest pain was felt in the Testing Products segment, where revenue fell 21%, reflecting weak demand from OEMs — particularly in Europe — as well as the non-recurrence of a large North American robot delivery that had boosted the prior year. The effective tax rate also rose to 23.5% from 19.2%, further compressing earnings.

On the earnings call, CFO designate Ed Haycock acknowledged it was "a disappointing year" while pointing to the maintained 20% operating margin, an 80-basis-point improvement in gross margin, a 10% dividend increase, and a £31 million order book as evidence of underlying resilience.

Management guided FY 2027 adjusted operating profit in line with current expectations, though cautioned that cost savings from FY 2026 are expected to largely reverse as investment in innovation and sales resumes.

The broader UK market provided no shelter for the stock’s decline, with the FTSE 100 rising approximately 0.8% and the AIM All-Share also gaining around 0.8% on the day, supported by a rally in mining stocks.

AB Dynamics therefore underperformed its domestic market significantly, reflecting the company-specific nature of today’s selling pressure rather than any macro headwind.

The combination of a steep revenue miss versus the prior year, a 38% collapse in statutory operating profit, rising tax rates, and cautious forward commentary on overhead costs proved sufficient to override the positives of dividend growth and margin resilience, pushing the stock toward its 52-week low of 718p and well below its 52-week high of 1,350p.
