Spirax Finance Chief Exits RS Group Board Amid Scrutiny on Engineering Firm’s Stock Performance

The finance chief of the FTSE 100 manufacturing giant Spirax has officially stepped down from the board of RS Group. Louisa Burdett, who took up her role at the Cheltenham-headquartered engineering firm earlier in 2024, formally left her non-executive director position at the London-listed industrial distributor on January 31. She had been a fixture on the FTSE 250 company’s board since 2017, chairing the audit committee and bringing extensive expertise in commercial finance, risk management, and mergers and acquisitions. Before joining Spirax, Burdett built a formidable resume across the British corporate landscape. Her previous stints include chief financial officer roles at Croda International, Meggitt, Optos, and the Financial Times Group, alongside a tenure as group finance director for Victrex.

Global Footprint

Her current employer, Spirax Group, operates on a massive scale. Operating across 68 countries with a workforce of around 10,000 staff, the manufacturer runs 30 production plants worldwide. The business itself is divided into three core divisions: steam thermal, electric thermal, and fluid technology. Yet despite this robust operational footing, the company’s performance on the stock market paints a slightly more complicated picture for investors looking for reliable returns.

Market Performance and Volatility

While Spirax-Sarco shares have technically grown over the past decade, recent market analysis suggests the stock might actually be acting as a drag on investor portfolios. Over a ten-year period, the firm’s shares posted a net gain of 67.8 percent, which translates to a somewhat modest average annual return of 6.8 percent. To put that into perspective, an initial investment of €10,000 a decade ago would be worth approximately €16,780 today.

Financial analysts now classify the investment risk associated with the stock as remarkably high, citing a loss ratio of 2.97. When stacked against top-tier market ‘champions’—which have averaged around 17 percent in annual growth over the same timeframe with significantly fewer price drops—Spirax has notably underperformed. Ultimately, the engineering giant has struggled to deliver the consistent price premiums and downside protection that hallmark the most reliable long-term investments.
