We are registering the offer and sale of the securities described above to satisfy certain
registration rights we have granted. Our registration of the securities covered by this prospectus does not mean that the Selling Stockholders will offer or sell any of the securities. The Selling Stockholders may offer and sell the securities
covered by this prospectus in a number of different ways and at varying prices. Additional information on the Selling Stockholders, and the times and manner in which they may offer and sell the securities under this prospectus, is provided under

The Common Stock is listed on the Nasdaq
Capital Market under the symbol DTI. On August 29, 2023, the closing price of the Common Stock was $4.02 per share.
The shares of Common Stock being offered for resale pursuant to this prospectus by the Selling Stockholders represent the large majority
(approximately 85.6%) of the shares of Common Stock outstanding as of August 30, 2023 (assuming the issuance of all 1,761,570 shares of Common Stock subject to Options covered by this prospectus). The sale of all such shares, or the perception
that these sales could occur, could result in a significant decline in the public trading price of the shares of Common Stock. Even if the current trading price of the Common Stock is at or significantly below $10.00 per share, the price at which
the ROC Units (as defined herein) were issued in the ROC IPO (as defined herein), certain of the Selling Stockholders, including holders of Founder Shares, Exchange Shares (as defined herein) and shares of Common Stock issuable upon exercise of
certain outstanding Options and Alberto Pontonio (an affiliate of ROC Holdings), may have an incentive to sell because they will still profit on sales due to the lower price at which they purchased their shares compared to the public stockholders.
See Risk Factors Risks Related to Ownership of the Common Stock Sales of substantial amounts of Common Stock in the public markets, or the perception that such sales could occur, could reduce the price that the Common Stock
might otherwise attain. The shares being offered for resale in this prospectus represent a substantial percentage of the outstanding Common Stock, and the sales of such shares, or the perception that these sales could occur, could cause the market
price of the Common Stock to decline significantly. Additionally, certain Selling Stockholders, including holders of Founder Shares, Exchange Shares and shares of Common Stock issuable upon exercise of certain outstanding Options and
Alberto Pontonio (an affiliate of ROC Holdings), may experience a positive rate of return on the sale of their shares covered by this prospectus even if the market price per share of Common Stock is below $10.00 per share, while the public
stockholders may not experience a similar rate of return on the securities they purchased due to differences in the purchase prices and the current trading price. See Risk Factors Risks Related to Ownership of the Common
Stock Certain Selling Stockholders can earn a positive return on their investment, even if other stockholders experience a negative rate of return on their investment in DTIC.
We are an emerging growth company, as that term is defined under the federal securities laws and, as such, are subject to certain
reduced public company reporting requirements.
