The broader German small-cap benchmark SDAX, where SMA Solar is a constituent according to the same ad-hoc-news report, also advanced on September 17, 2026, so the stock’s 0.9 percent gain roughly tracked a firmer market backdrop while still lagging its own earlier highs. Per the ad-hoc-news overview, the company’s market capitalization was around EUR 1.9 billion at the EUR 55.80 closing level as of September 17, 2026, offering additional context for the session move in relation to the company’s size.
Factory opening shapes today’s view
The main driver behind the latest session’s advance was the formal opening of SMA Solar’s new Gigawatt Factory production site at its headquarters in Niestetal near Kassel on September 17, 2026, an event that the company and several media outlets highlighted as a major strategic step. As the German broadcaster FFH reported on September 17, 2026, SMA Solar officially inaugurated the Gigawatt Factory, describing it as a key facility for the energy transition. In a separate report on the same date, MarketScreener noted that SMA invested about EUR 80 million in the new plant and aims for more than 60 gigawatts of annual production capacity at full load, underscoring the scale of the project. An English-language session wrap at ad-hoc-news explicitly linked the 0.9 percent rise in SMA Solar stock on September 17, 2026 to investor response to the Gigawatt Factory opening.
Heading into today’s session on September 18, 2026, the new factory remains the central focus for SMA Solar’s equity story, as markets weigh how the additional capacity and the roughly EUR 80 million investment can support future revenue and earnings. MarketScreener pointed out that, alongside the factory news, investors still have in view the company’s latest quarterly figures for the period ended June 30, 2026, where SMA Solar reported earnings per share of EUR 2.14 compared with EUR -1.38 a year earlier, even as revenue edged down to around EUR 345.69 million from EUR 357.15 million.ad-hoc-news That mix of stronger profitability, slightly lower revenue and significant new capacity investment frames expectations for SMA Solar stock today, even though no specific new company events or scheduled releases for September 18, 2026 are highlighted in the latest investor-relations and media coverage.
