<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in">On October 10, 2023, ADC Therapeutics SA (the &ldquo;Company&rdquo;)
received a notice from the New York Stock Exchange (&ldquo;NYSE&rdquo;) that the Company is not in compliance with the continued listing
minimum price criteria set forth in Section 802.01C of the NYSE Listed Company Manual, which requires listed companies to maintain an
average closing share price of at least $1.00 over a consecutive 30 trading-day period. In accordance with Section 802.01C of the NYSE
Listed Company Manual, the Company has a period of six months from receipt of the notice to regain compliance with the continued listing
minimum price criteria. The notice has no immediate impact on the listing of the Company&rsquo;s common shares, which will remain listed
and traded on the NYSE during this period, subject to the Company&rsquo;s compliance with the other continued listing requirements. The
Company can regain compliance at any time during the six-month cure period if on the last trading day of any calendar month during the
cure period the Company&rsquo;s common shares have a closing share price of at least $1.00 and an average closing share price of at least
$1.00 over the 30 trading-day period ending on the last trading day of that month. The Company has notified the NYSE of its intent to
cure the deficiency, which may include, if necessary, effecting a reverse share split, subject to board and shareholder approval. There
can be no assurance that the Company will be able to regain compliance with NYSE&rsquo;s continued listing minimum price criteria or remain
in compliance with other continued listing requirements or that the Company&rsquo;s common shares will continue to be listed on the NYSE.</P>
