[Urgent Purchase · Final Offer] Solar Panels & Battery Storage Systems Confirmed for Significant Price Increase After April 1, 2026! Place Your Order Now for Up to ~9% Cost Savings! TO: All Customers Considering the Purchase of Solar Panels and Battery Storage Systems Dear Sir or Madam, As we welcome the new year, we extend our warmest greetings and wish your esteemed company continued prosperity. We sincerely thank you for your ongoing patronage and support. Due to rapid changes in the export market environment, we are issuing this urgent notice and purchase recommendation. To maximize your cost benefits, SEAFOREST strongly advises you to place your order immediately and ensure shipment is completed by April 1, 2026. [Background Requiring Urgent Action: Triple Factors Driving Cost Surges] The solar panel and battery storage system market is currently experiencing a sharp rise in manufacturing and export costs due to the following unavoidable factors: Global Surge in Raw Material Prices: Prices for key raw materials of solar panels and battery storage systems have skyrocketed, driving up manufacturing costs. Appreciation of the Chinese Yuan (CNY) Exchange Rate: The stronger CNY has increased import costs in Japanese Yen terms. Phased Elimination of Chinese Government Export Tax Rebate Policy (The Most Critical Factor): After April 1, 2026: Export tax rebate for solar panels will be reduced from 9% to 0% (complete elimination). Rebate for battery storage systems will be reduced from 9% to 6%. After January 1, 2027: Rebate for battery storage systems is expected to be further reduced, moving towards complete elimination. The combined effect of these factors means that for orders placed after April 1st, a real purchase cost increase of approximately 9% for solar panels and about 3% for battery storage systems is unavoidable.

2026 New Year Greetings and Continuing Our Partnership With the arrival of the new year, Sea Forest Trading (SEA FOREST) has officially commenced operations. We would like to extend our heartfelt gratitude to all our partners and clients for your support thus far, and we look forward to your continued collaboration and partnership in the year ahead. Together, let us deepen our cooperation and explore new possibilities in the field of energy storage. I. 2025 Global Power Battery Market: The Dawn of the TWh Era and Structural Transformation According to data from SNE Research, the global installed capacity of power batteries from January to November 2025 exceeded 1 TWh (1,046 GWh) for the first time, representing a year-on-year increase of 32.6%. Three key trends have emerged in the market: the strengthening dominance of Chinese companies, the rise of lithium iron phosphate (LFP) technology, and the expansion of competition into energy storage and globalization. II. Key Analysis: Chinese Companies Leading, Market Structure Reshaped (I) Chinese Companies Take the Lead Across the Board Six Chinese companies occupy spots in the TOP 10, with a combined market share of 69.4%. The top two players, CATL and BYD, account for 54.9% of the market. Many Chinese companies achieved growth rates exceeding 70%, far surpassing the market average. (II) Technological Shift Toward Lithium Iron Phosphate The cost-effectiveness of LFP batteries has accelerated their global adoption, particularly in the Chinese market. International automakers are rapidly adopting this technology, reshaping supply chains. Japanese and Korean companies that have long focused on ternary batteries are struggling to maintain market share. (III) Evolving Competitive Landscape: Energy Storage as the Second Growth Driver The rapid expansion of energy storage demand has prompted top companies to accelerate their "power battery + energy storage" dual-strategy. Competition is shifting from production capacity expansion to comprehensive capabilities, including technology, customer portfolio, and global operations. III. January–November 2025 Global Power Battery Installed Capacity TOP 10 CATL - China | The undisputed global leader BYD - China | Advantages in vertical integration and LFP technology LG Energy Solution (LGES) - South Korea | Leading Korean company, facing growth pressure CALB - China | Maintaining a strong position, continuing to expand Panasonic - Japan | Leading in technology and quality, with challenges in cost competitiveness Gotion High-tech - China | Over 70% growth, accelerating internationalization EVE Energy - China | Over 70% growth, advancing in both power and energy storage Samsung SDI - South Korea | Declining market share, facing business transformation pressure SVOLT - China | Over 70% growth, cobalt-free batteries gaining attention SK On - South Korea | Facing intensified competition and market share pressure Regional Comparison: Chinese Companies: Six companies in the...

Ford Terminates $80 Billion Partnership, Pivots with Massive Investment into the Energy Storage Arena 1. Event Overview: A Strategic Shift in Focus Ford has ended its battery joint venture with SK On and announced a $20 billion investment to retool production lines for energy storage. This strategic shift highlights the growing importance of the storage sector and reflects deeper industry transformation. 2. Industry Trend: Energy Storage Becomes a Key Battleground for Cross-Sector Giants The global lithium battery energy storage market continues to grow rapidly, with installations up approximately 68% year-over-year in the first three quarters of 2025. Driven by policy support and market demand, energy storage has attracted at least 22 listed companies from diverse sectors, including automotive and solar. 3. Core Drivers: Technology Synergy and New Demand Scenarios Automakers leverage their battery expertise and mass-production capabilities, providing a natural advantage in energy storage. Meanwhile, emerging applications like AI data centers are fueling explosive demand—a single 100MW data center can require 450–800 MWh of storage. U.S. energy storage additions from 2026–2027 are projected to exceed 120 GWh. 4. Challenges and Risks: Price Competition and Market Consolidation Despite strong prospects, the industry faces intense pricing pressure. The global average price for energy storage systems fell about 31% year-over-year in 2025. Nearly one-third of system integrators operate at a loss, with over 40% of smaller players exiting the market. 5. Industry Impact: From Product Competition to Ecosystem Rivalry Chinese companies lead in battery cell production, but the entry of global giants is shifting competition from hardware sales to integrated “manufacturing + software + service” ecosystems. Technology and comprehensive solutions are becoming key differentiators. 6.
