GLOBAL CRISES IMPACTING DUE DILIGENCE INVESTIGATION MARKETCOVID-19 IMPACT

Due Diligence Investigation Market Had a Negative Effect Due to Supply Chain Disruption During COVID-19 Pandemic

The global COVID-19 pandemic has been unprecedented and staggering, with the market experiencing lower-than-anticipated demand across all regions compared to pre-pandemic levels. The sudden market growth reflected by the rise in CAGR is attributable to the market’s growth and demand returning to pre-pandemic levels.

In the beginning, it could be seen that the due diligence investigation market share was affected negatively by the COVID-19 pandemic as the business activities of the globe came to a halt and financial markets became uncertain. The demand of the due diligence services was negatively affected as many M&A transactions, investment deals, and corporate expansions were delayed or binned. Lockdowns and associated travel limitations also prevented onsite investigations, face-to-face interviews and onsite audit, all important parts of conventional due diligence. Organizational issues lay in the fact that it had difficulties in obtaining relevant data or documentation available with target companies particularly in cross-border situations. Furthermore, legal teams and departments were too busy with regulatory updates related to the pandemic, which left them with little time to focus on dealing and corporate assessments. The venture capital and the private equity industry would also pursue a much less aggressive investing strategy, postponing investment rounds and purchases. Consequently, service providers faced revenue loss and deferrals of projects in the first quarters of the observed pandemic. Nevertheless, the scenario could later result in a change of due diligence execution, where there will be an even greater rise in the digitization of efforts, remote evaluation approaches, and online verification systems. Although the immediate effects were disruptive, the pandemic has led to the increased speed of digital adoption and underlined the use of proactive risk assessment, which will change the future of due diligence services.
