(the &#8220;Company&#8221;) filed a Certificate of Amendment to its Restated Certificate of Incorporation (the &#8220;Charter Amendment&#8221;) with the Secretary of State of the State of Delaware to effect a <span style="white-space:nowrap"><span style="white-space:nowrap">1-for-20</span></span> reverse stock split (the &#8220;Reverse Stock Split&#8221;) of the Company&#8217;s common stock, par value $0.001 per share (the &#8220;Common Stock&#8221;), effective April&#160;21, 2025 at 5:00 p.m., Eastern Time (the &#8220;Effective Time&#8221;). The Company&#8217;s Common Stock began trading on a split-adjusted basis on The Nasdaq Global Select Market at the commencement of trading on April&#160;22, 2025 under the Company&#8217;s existing trading symbol &#8220;MCRB&#8221;. The new CUSIP number for the Common Stock following the Reverse Stock Split is 81750R 201. </p> <p style="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">As previously reported, at its Annual Meeting of Stockholders held on April&#160;10, 2025, and upon the recommendation of the Company&#8217;s Board of Directors (the &#8220;Board&#8221;), the Company&#8217;s stockholders approved amendments to the Restated Certificate of Incorporation to effect a reverse stock split of the Common Stock at a ratio ranging from any whole number between <span style="white-space:nowrap"><span style="white-space:nowrap">1-for-5</span></span> and <span style="white-space:nowrap"><span style="white-space:nowrap">1-for-50,</span></span> as determined by the Board in its discretion. On April&#160;10, 2025, the Board approved a final Reverse Stock Split ratio of <span style="white-space:nowrap"><span style="white-space:nowrap">1-for-20</span></span> and abandoned all other reverse stock split amendments at different ratios. </p> <p style="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">As a result of the Reverse Stock Split, at the Effective Time, every 20 shares of the Company&#8217;s issued and outstanding shares of Common Stock immediately prior to the Effective Time, were automatically converted, without any action on the part of the holder thereof, into one validly issued, fully-paid and <span style="white-space:nowrap">non-assessable</span> share of Common Stock, subject to the treatment of fractional shares as described below. The Charter Amendment did not affect the number of authorized shares of Common Stock or the par value of each share of Common Stock. </p> <p style="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">No fractional shares of Common Stock will be issued as a result of the Reverse Stock Split.
