to the satisfaction or waiver of the conditions set forth in the Merger Agreement, Atlas Merger Sub Corp, a Delaware corporation and

August 16, 2024, ARCA issued a press release announcing that its Board of Directors has declared a special cash dividend to its stockholders
in connection with the Merger (the &#8220;<span style="text-decoration: underline">Special Dividend</span>&#8221;). The Special Dividend, which ARCA estimates to be $1.59 per
share of ARCA&#8217;s common stock, will be payable in cash to the stockholders of record as of August 26, 2024. The exact amount of
the Special Dividend will be calculated pursuant to the Merger Agreement and based on ARCA&#8217;s reasonable, good faith approximation
of the amount by which ARCA&#8217;s net cash, as determined  prior to the closing of the Merger, will
exceed $5,000,000. Total actual distribution of the amount of the Special Dividend could be higher or lower than $1.59 per share and
the estimate for amount to be distributed to stockholders could change. The payment date in respect of the Special Dividend is scheduled
for August 28, 2024.</span></p>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">The Special Dividend, which ARCA estimates will be $1.59 per share
of ARCA&rsquo;s common stock, will be payable in cash to the stockholders of record as of August 26, 2024. The exact amount of the Special
Dividend will be calculated pursuant to the Merger Agreement and based on ARCA&rsquo;s reasonable, good faith approximation of the amount
by which ARCA&rsquo;s net cash, as determined prior to the closing of the Merger, will exceed $5,000,000.
Total actual distribution of the amount of the Special Dividend could be higher or lower than $1.59 per share and the estimate for amount
to be distributed to stockholders could change. The payment date in respect of the Special Dividend is scheduled for August 28, 2024.</P>

ARCA stockholders of the Merger, which ARCA&rsquo;s stockholders will consider and vote upon at the special meeting of ARCA stockholders
scheduled for 9:00 a.m. MT on August 22, 2024. Closing of the Merger is expected to occur on August 29, 2024 assuming
that the transaction is approved by ARCA&rsquo;s stockholders and the satisfaction or waiver of all conditions under the Merger Agreement.</P>
