The reverse stock split was implemented by the Company in connection with its application to uplist the Company’s common stock to a national exchange. The reverse stock split is intended to fulfill the stock price requirements for initial listing on a national exchange.

As a result of the reverse stock split, every two hundred pre-split shares of common stock outstanding and authorized will automatically combine into one new share of common stock without any action on the part of the shareholders.

No fractional shares will be issued in connection with the reverse stock split. Any fractional shares of common stock resulting from the reverse stock split will be rounded up to the nearest whole post-split share and no shareholders will receive cash in lieu of fractional shares. The reverse stock split will also apply to common stock issuable upon the conversion of Arch’s outstanding convertible notes and the exercise of Arch’s outstanding warrants, restricted stock units, and stock options, with adjustments to the conversion prices and exercise prices thereof as required by the terms of those securities.

On September 29, 2022, the Company’s shareholders approved the reverse stock split and granted the Company’s board of directors discretionary authority to select a ratio for the split ranging from 1-for-100 to 1-for-200 as well as the increase in authorized shares by 300%.
