&lt;p style="font: 9pt/115% Times New Roman, Times, Serif; margin: 0 7.5pt 0 0; text-align: justify"&gt;The TANAKA Growth Fund gained 37.0%
for its fiscal 2025 ending November 30&lt;sup&gt;th&lt;/sup&gt; compared with gains of 16.8% for the Wilshire 2500 Growth index and 15.0% for the
S&amp;amp;P 500. Mega Cap Tech and Artificial Intelligence continued to dominate market leadership during the year, and while the Fund benefited
from holdings aligned with the AI infrastructure cycle, much of our outperformance was driven by small- and mid-cap stock picks in areas
such as Health Care, Energy, Gold, and Critical Minerals. Performance was broad-based with three holdings up over 200%, eight up more
than 40%, and ten up more than 20% during the fiscal year.&lt;/p&gt;

&lt;p style="font: 9pt/115% Times New Roman, Times, Serif; margin: 0 7.5pt 0 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 9pt/115% Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Two mid-cap Biotech stock picks were among the Fund&#x2019;s top contributors,
benefiting from strong commercial drug sales and positive clinical trial developments. Several metals and mining-related positions also
contributed meaningfully to results, including a Gold producer that benefited from higher gold prices and the start-up of a new mine,
Uranium holdings that gained amid rising demand for nuclear power, and a Critical Minerals company that secured large government and
commercial contracts and is expanding its production capabilities. Our core Semiconductor and Semi Capital Equipment companies continued
to play important roles in the AI infrastructure buildout while our Warehouse Automation holding remains a strong example of the productivity
and cost efficiencies enabled by AI adoption. Partially offsetting these gains was a decline in an inverse S&amp;amp;P 500 ETF used as a
market hedge, which we subsequently sold as markets recovered from the spring tariff-driven correction. In addition, one of our small-cap
Biotech companies lagged following a clinical trial disruption, and our Consumer Staples and Financials positions underperformed the
market as investor focus remained concentrated in Technology and AI.&lt;/p&gt;

&lt;p style="font: 9pt/115% Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 9pt/115% Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;As we enter the new year, our investment approach
remains unchanged: focusing on companies with identifiable company-specific growth drivers that may be less dependent on broader market
or macroeconomic conditions. We believe the continued growth of passive investing and increased market concentration are contributing
to meaningful disconnects between stock prices and underlying fundamentals, particularly outside of Large Cap Technology. In our view,
this environment creates a favorable backdrop for active investors like us to research and identify high-quality companies across sectors
and market capitalizations that may be overlooked despite attractive long-term prospects.&lt;/p&gt;
