BofA Initiates SigmaRoc with 'Buy' Rating on Lime Pricing and M&A Outlook

BofA Securities initiated coverage of European lime producer SigmaRoc on Wednesday with a “Buy” rating and a 162 pence price target, forecasting significant upside based on the company's pricing strength in the lime market and its potential for further acquisitions.

The price target implies a 27.4% upside from SigmaRoc's share price of 127.20 pence, as cited in the note. BofA's analysts project an 11% compound annual growth rate (CAGR) in earnings per share (EPS) for the company between fiscal 2025 and 2028.

Analyst's Thesis

The bank's valuation is based on a discounted cash flow (DCF) model and the potential for future deals. Key components of the target price include:

• 142 pence derived from a DCF valuation, which assumes an 11.5% weighted average cost of capital (WACC) and 2% terminal growth.
• An additional 20 pence attributed to potential M&A activity, adding 14% to the base valuation.

BofA's EBIT forecasts are 2% above consensus for fiscal 2027 and 4% above for fiscal 2028. The bank also anticipates revenues will be 2% to 3% higher than consensus estimates for both years, driven by pricing, volume recovery, and acquisition synergies.

Pricing Power and Volume Recovery

Ad

Lime, which accounts for 71% of SigmaRoc’s revenue, is a key driver of the positive outlook. BofA highlighted that U.S. producer-price data shows lime prices have historically risen at a 6% annualized rate since 2000. The bank expects SigmaRoc to sustain annual price increases of 3% to 5%.

Analysts also noted a positive shift in demand, with underlying volumes rising 1% in the first half of the year—the first increase since 2022. This recovery is supported by German infrastructure stimulus, European steel tariffs, and improving construction activity, according to the report.

Acquisition Strategy and Valuation

BofA expects SigmaRoc to pursue up to £175 million in bolt-on acquisitions, with potential cost synergies of 20% to 30%. Recent deals are forecast to contribute 40% of EBIT growth in fiscal 2027, while future acquisitions could add another 3% to 5% to annual EPS growth.

The bank projects SigmaRoc's leverage will fall below its target range of 1.5-to-2 times by fiscal 2027, creating about £140 million in capacity for M&A. SigmaRoc currently trades at approximately 7.2 times its estimated fiscal 2026 enterprise value to EBITDA (EV/EBITDA). BofA pointed to Martin Marietta’s acquisition of Lhoist’s North American lime business at a 15 times EV/EBITDA multiple as a valuation benchmark for scaled assets in the sector.
