(the \"Company”) held a special meeting\nof stockholders (the \"Special Meeting”) on April 30, 2026. At the Special Meeting, the Company’s stockholders approved\nthe proposal to grant discretionary authority to the Company’s Board of Directors (the “Board”) to amend the Company’s\nAmended and Restated Certificate of Incorporation, as amended to date (the \"Charter”), in order to effect reverse stock splits\nof all of the outstanding shares of its issued and outstanding common stock, par value $0.00001 (the \"Common Stock”), at a\nratio in the range of one-for-two (1:2) to one-for-ten (1:10) at any time prior to the one-year anniversary date of the Special Meeting,\nwith such ratio to be determined by the Board, provided that the Company shall not effect reverse stock splits that, in the aggregate,\nexceed 1-for-100 (the \"Reverse Stock Split Proposal”).\n\n \n\nOn\nMay 8, 2026, the Board determined to fix a reverse stock split ratio of its Common Stock of 1-for-10 (the \"Reverse Stock Split”).\nOn May 20, 2026, the Company expects to file an amendment to its Charter with the Secretary of State of the State of Delaware (the “Amendment”)\nto effect the Reverse Stock Split. The Reverse Stock Split will become effective in accordance with the terms of the Amendment at 12:01\na.m. Eastern Time on May 21, 2026 (the \"Effective Time”). The Company’s Common Stock will begin trading on a split-adjusted\nbasis when the Nasdaq Stock Market opens on May 21, 2026 under the symbol ONCO, under a new CUSIP number, 68237Q 401. The Reverse Stock\nSplit is primarily intended to bring the Company into compliance with The Nasdaq Stock Market, LLC’s rule on minimum bid price requirements.\n\n \n\nAt\nthe Effective Time, every 10 (ten) shares of the Company’s issued and outstanding Common Stock will convert automatically into one\n(1) issued and outstanding share of Common Stock, with no corresponding reduction in the number of authorized shares of Common Stock,\nand without any change in the par value per share. Stockholders holding shares through a brokerage account will have their shares automatically\nadjusted to reflect the 1-for-10 Reverse Stock Split. It is not necessary for stockholders holding shares of the Common Stock in certificated\nform to exchange their existing stock certificates for new stock certificates of the Company in connection with the Reverse Stock Split,\nalthough stockholders may do so if they wish.\n\n \n\nThe Reverse Stock Split will\naffect all stockholders uniformly and will not alter any stockholder’s percentage interest in the Company’s equity, except\nto the extent that the Reverse Stock Split would result in a stockholder owning a fractional share. No fractional shares will be issued\nin connection with the Reverse Stock Split. Stockholders who would otherwise be entitled to receive a fractional share will instead receive\na cash payment (without interest) equal to such fraction multiplied by the closing sale price per share of the Common Stock on The Nasdaq\nCapital Market at the close of business on the date prior to the effective date of the Reverse Stock Split, or May 20, 2026 (with such\nclosing sale price being adjusted to give effect to the Reverse Stock Split). The Reverse Stock Split will reduce the number of outstanding\nshares of the Company’s common stock from approximately 11.4 million to approximately 1.14 million.\n\n \n\nProportional adjustments will\nbe made to the number of shares of Common Stock issuable upon exercise or conversion of the Company’s equity awards, convertible\npreferred stock and warrants, as well as the applicable exercise price. Stockholders with shares in brokerage accounts should direct any\nquestions concerning the Reverse Stock Split to their broker; all other stockholders may direct questions to the Company’s transfer\nagent, Continental Stock Transfer & Trust Company, at 212-509-4000.\n\n \n\nThe\nforegoing description of the Amendment does not purport to be complete and is qualified in its entirety by reference to the full text\nof the Amendment, which is filed as Exhibit 3.1 to this Current Report on Form 8-K and incorporated by reference herein.\n\n \n\n1"}
