Solaria Energía y Medio Ambiente (SLR) is no longer just a solar company. While it remains a leader in Iberian photovoltaic technology, the company is undergoing a transformation by diversifying into the high-demand world of AI and data infrastructure.

The stock has staged a dramatic recovery, currently trading around €18/share. CEO Arturo Diaz-Tejeiro recently highlighted that the company is “extremely excited” about its new data center division, which leverages Solaria’s existing grid connections and land bank.

With over 4.4 GW of capacity currently under construction or connected, Solaria is transforming into a diversified energy powerhouse.

What the Model Says for SLR Stock

We evaluated Solaria’s potential by looking out to December 2029, factoring in the capital-intensive nature of its transition into batteries and data centers.

Using a forecast of 27.3% Revenue Growth (CAGR) and robust 67.3% Operating Margins, our model projects a target price of €21.39 by late 2027.

This assumes an Exit P/E Multiple of 12.7x, reflecting its transition toward a more stable, utility-like earnings profile.

Our Valuation Assumptions

TIKR’s Valuation Model lets you plug in your own assumptions for a company’s revenue growth, operating margins, and P/E multiple, and calculates the stock’s expected returns.

Here’s what we used for SLR stock:

1. Revenue Growth: 27.3%

27.3% Solaria is in hyper-growth, aiming for 3 GW of solar capacity by end-of-2025 and a massive 9 GW by 2027. Beyond solar, the company is pivoting into AI data centers and battery storage (BESS) using existing grid connections.

The company expects momentum from its Generia division, which offers land and grid solutions for AI companies seeking sustainable energy. This diversification creates a high-margin recurring revenue stream independent of power price volatility.

2. Operating Margins: 67.3%

Solaria maintains industry-leading margins through an in-house model that manages every stage from land acquisition to grid connection. This integration allows for record-low CapEx, such as battery storage costing just €75,000 per MWh.

Long-term Power Purchase Agreements (PPAs) support margin maintenance by locking in prices and insulating the company from price volatility. Predictability allows the company to fund massive expansion through cash flow and efficient project finance.

Management targets sustainable margins by remaining the lowest-cost developer while scaling high-margin data center verticals.

3. Exit P/E Multiple: 12.7x

SLR stock currently trades at multiples reflecting hyper-growth, though our model assumes a transition toward a stable “green utility” valuation.

We maintain an Exit P/E of 12.7x, providing a significant margin of safety for investors as the company matures its pipeline.

Dominant Iberian grid access and a vertically integrated model should support attractive valuations as AI infrastructure begins to scale.

Different scenarios through 2029 highlight the impact of Solaria’s strategic pivot (these are estimates, not guaranteed returns):

  • Low Case: If construction delays occur or battery margins underperform → (3.2%) annual return.
  • Mid Case: If the company successfully scales its data center and storage units → 3.6% annual return.
  • High Case: If Solaria becomes the leader in Iberian solar + battery integration → 10.0% annual return.
