Eco Wave Power Reports Strong December 2025Wave Energy Performance at Jaffa Port, Reinforcing Scalability of Its Wave Energy Technology

Tel Aviv, Israel – (Newsfile Corp. –January 12, 2026) – Eco Wave Power Global AB (NASDAQ: WAVE) (“Eco Wave Power” or the “Company”), a global leader in onshore wave energy technology, is pleased to report strong wave energy production performance at its EWP-EDF One wave energy project at Jaffa Port, Israel, during December 2025.

Since the beginning of 2025, the EWP-EDF One system at Jaffa Port has maintained zero downtime, with stable operation recorded in wave conditions of 1 meter and above. During December 2025, over approximately 12 days characterized by moderate wave heights ranging between 1 and 2 meters, the project produced over 2,000 kWh of clean, renewable electricity.

These results further demonstrate the system’s ability to generate energy reliably under real-world sea conditions and provide valuable operational data supporting the continued advancement of wave energy technology.

The EWP-EDF One project at Jaffa Port is a pilot-scaledemonstration array, consisting of a limited number of small-scale floaters, designed primarily to validate continuous operation, system robustness, and real-world energy production under varying sea conditions. The strong performance recorded during December 2025 confirms the scalability potential of Eco Wave Power’s proprietary technology and supports the Company’s transition toward larger, commercial-scale deployments.

Future commercial projects are planned to utilize larger floaters and a significantly higher number of units, a configuration expected to materially enhance energy capture, improve capacity factors, and deliver a substantially more powerful and stable production profile compared to pilot installations. These results reinforce the role of wave energy as a predictable and complementary renewable energy source in suitable coastal locations.

Eco Wave Power’s continued success at Jaffa Port highlights the Company’s commitment to advancing wave energy from demonstration to commercial application, while systematically collecting performance data to optimize future project designs.

In parallel with its activities in Israel, Eco Wave Power continues to expand its global footprint. In September 2025, the Company successfully launched and inaugurated itswave energy project at AltaSea in the Port of Los Angeles, developed in collaboration with Shell MRE, following the receipt of all required regulatory approvals, including a federal license from the U.S. Army Corps of Engineers. In addition, Eco Wave Power continues to advance projects in Taiwan, in collaboration with I-KE, in India- in collaboration with Fortune500 Bharat Petroleum, and in Portugal, where the Company is preparing to deploy its largest installation to date, using its proprietary technology in one of Europe’s most dynamic marine energy environments.

“We are very encouraged by the performance of our EWP-EDF One project at Jaffa Port during December 2025,” said Inna Braverman, CEO and Founder of Eco Wave Power. “While this system is a pilot installation, it continues to deliver important real-world performance data that directly informs our commercial designs. As we scale to larger floaters and expanded arrays, we expect to unlock a significantly stronger production profile and move wave energy closer to large-scale commercial deployment.”

Eco Wave Power’s innovative wave energy systems are designed to be efficient, scalable, and environmentally responsible, offering a sustainable alternative to conventional power generation. With projects operational and under development across multiple geographies, the Company continues to demonstrate that ocean waves can play an important role in building a resilient and diversified renewable energy future.
