After the PCA, a panel probit regression model was used to analyze delisting determinants. This aimed to predict delisting likelihood by examining 20 non-financial variables from PCA and nine macroeconomic determinants. Data from 2000 to 2023 included 302 delisted and 302 still listed companies. The dependent variable was listing status, classified as delisted (1) or remained listed (0). The results include initial model outcomes, stepwise elimination of insignificant determinants, and the final model’s results.
4.2.1. Results Form the Initial Model and Stepwise Ellimination of Insignificant Variables
The comprehensive model in
Table 12 includes all 29 determinants. Analysis shows several determinants significantly impact delisting probability, with p-values less than 0.05. Some variables have even stronger significance with p-values below 0.001, emphasizing their critical role in predicting delisting. These findings highlight the combined influence of non-financial and macroeconomic determinants, providing a robust framework for understanding and mitigating delisting probabilities. A 10% p-value threshold was not used to minimize Type I errors, ensuring robustness and reliability (Baltagi et al., 2016).
The Pseudo-R
2 value of 0.82 (see
Table 13) signifies strong explanatory power, indicating that the model accounts for approximately 82% of the variability in delisting probability (Mullahy, 2016). Additionally, the Wald chi-square statistic of 378.13, with a p-value of less than 0.001, confirms the combined relevance of the predictors included in the model (Baltagi et al., 2016).
As shown in
Table 12, four non-financial determinants were strongly related to predicting the probability of delisting: governance transparency and independence (p-value < 0.001, coefficient = -0.19), chairperson qualification (p-value = 0.031, coefficient = 0.074), company longevity and listing duration (p-value < 0.001, coefficient = -0.18), and number of analyst recommendations (p-value < 0.001, coefficient = -0.26). These findings suggest that improvements in these areas decrease the probability of delisting.
Furthermore, four macroeconomic determinants were significant: inflation (p-value = 0.033, coefficient = -0.11), repo rate (p-value < 0.001, coefficient = 0.028), credit extensions (p-value < 0.001, coefficient = -0.078), and unemployment rates (p-value < 0.001, coefficient = 0.039). Higher inflation and increased credit availability were associated with a lower delisting probability, while higher interest and unemployment rates were linked to a higher delisting probability. These findings are supported by literature such as Campbell et al. (2008), Donker et al. (2009), and Matadeen (2017), which emphasize the complex interplay between financial stability, economic conditions, and firm performance in determining delisting risks. However, our research shows an interconnectedness between non-financial determinants and macroeconomic variables in relation to delistings as well.
After the initial model, a stepwise elimination of insignificant variables was employed to refine the multivariate model. This process involved repeated regressions, removing the least significant variable, and refitting the model. This continued until only significant variables remained. Stepwise elimination was chosen for its efficiency in refining the model without compromising its integrity. Cross-validation techniques were used to ensure robustness (Mullahy, 2016). This methodical approach streamlined the model, highlighting essential determinants and enhancing predictive accuracy and interpretability.
4.2.1. Final Panel Probit Regression Results
After the stepwise elimination of insignificant variables, the final multivariate model is shown in
Table 14. It includes three additional determinants compared to the comprehensive model in
Table 12: ’ownership diffusion component’, ’institutional influence’, and ’real economic activity’ through the measure of electricity generation and distribution within South Africa.
The Pseudo-R
2 value of 0.79 indicates strong explanatory power, accounting for approximately 79% of the variability in delisting probability (Mullahy, 2016). This reflects the model’s effectiveness in capturing key determinants of delisting. Additionally, the Wald chi-square statistic of 341.62, with a p-value of less than 0.001, confirms the overall significance of the model, indicating that the predictors collectively have a significant impact on delisting probability (see
Table 15).
Several key non-financial variables are significant in predicting the probability of delisting, as shown in
Table 14. These include ’governance transparency and independence’, ’ownership diffusion component’, ’institutional influence’, ’chairperson qualification’, ’company longevity and listing duration’, ’number of analyst recommendations’, ’inflation’, ’repo rate’, ’credit extensions’, ’unemployment rate’, and real economic activity measures by electricity generation and distribution within South Africa. The significant non-financial and macroeconomic delisting determinants from the final model are discussed below.
First, the composition of the governing body, particularly in terms of governance transparency and independence, is a significant factor influencing delisting. This includes the percentage of independent directors, whether the chairperson is an independent non-executive director, and the Bloomberg governance disclosure score. With a p-value of < 0.001 and an estimated coefficient of -0.12, higher governance transparency and independence are linked to a lower probability of delisting. Companies with more independent directors and an independent chairperson are less likely to delist, showcasing the stabilizing effect of robust governance practices. This is supported by literature, including Anderson & David (2003) and Jensen & Meckling (1976), which emphasize the importance of strong governance in reducing agency costs and enhancing company value and investor confidence.
Agency theory underscores the role of independent directors in aligning management and shareholder interests by enhancing board oversight and reducing agency costs (Jensen & Meckling, 1976). Stakeholder theory suggests that good governance builds trust and confidence among all stakeholders, crucial for long-term viability (Mahajan et al., 2023). Empirical studies, such as Hsu & Wu (2014), further support these findings, highlighting that firms with more independent directors experience lower financial distress and delisting risks.
Diffused ownership, referred to as the ’ownership diffusion component’, is another crucial determinant for delisting from our model. This includes the percentage of public shareholders and individual investors. Though initially not significant, it emerged as important in the final analysis with a p-value of 0.020 and an estimated coefficient of -0.15 (see
Table 14). Greater ownership diffusion, characterized by more public shareholders and individual investors, lowers the likelihood of delisting. This broader base reduces the risks of concentrated control and enhances stability, promoting balanced governance (Boot et al., 2006). This finding is supported by literature such as Djerbi & Anis (2015), which highlights the benefits of dispersed ownership in reducing agency costs and improving corporate governance.
In this regard, agency theory suggests that diverse ownership structures mitigate conflicts of interest between management and shareholders, increasing scrutiny and accountability, and reducing delisting risks (Donaldson & Davis, 1991). Stakeholder theory also values diffused ownership, as it demonstrates inclusiveness and responsiveness to a broader range of interests, enhancing trust and confidence. Empirical studies, like those by Boot et al. (2006) and Donker et al. (2009), validate that diffused ownership leads to more effective monitoring, better corporate outcomes, and lower delisting risks.
We also found institutional investors to play a crucial role in reducing the probability of delisting. This determinant, labelled ’institutional influence’, is measured by the percentage of institutional investors and has a p-value of 0.008 with a coefficient of -0.16 (see
Table 14). The negative coefficient suggests that a higher percentage of institutional investors is associated with a lower probability of delisting, as their stability and oversight could enhance corporate governance and strategic decision-making. Agency theory highlights that institutional investors help monitor management and reduce agency costs, ensuring that management acts in shareholders’ best interests. Signaling theory adds that their presence signals market confidence, thereby reducing delisting risks (Connelly et al., 2011). Empirical studies, including those by (Renneboog et al., 2007; Ting et al., 2008), support the importance of institutional investors in improving governance and reducing agency conflicts. However, we view high institutional ownership can sometimes lead to delisting if these investors push for strategic moves like mergers or buyouts to maximize shareholder value.
The biographical information of board members, specifically the ’chairperson qualification’, is another significant determinant. This determinant examines whether the chairperson holds a postgraduate or professional qualification, with a p-value of 0.021 and a coefficient of 0.071 (see
Table 14). The positive coefficient suggests that higher qualifications for the chairperson are associated with a slightly increased probability of delisting. Highly qualified chairpersons may identify strategic opportunities for mergers, acquisitions, or corporate restructuring that could lead to delisting. They may also be more inclined towards transformative strategies that, although beneficial in the long run, could cause temporary instability. Agency theory explains that a well-qualified chairperson can reduce agency costs by effectively monitoring management and ensuring alignment with shareholder interests. However, these qualifications could also empower the chairperson to initiate corporate changes, like delisting, if perceived to benefit the company and its shareholders. Signaling theory posits that the chairperson’s qualifications signal the company’s commitment to high standards of governance and strategic leadership, enhancing investor confidence.
The final model also identified ‘company longevity and listing duration’ to be a critical determinant in predicting the probability of delisting. With a p-value of 0.004 and an estimated coefficient of -0.14 (see
Table 14), this factor shows that longer company longevity and extended listing duration correlate with a lower probability of delisting. Established companies benefit from accumulated experience, strong stakeholder relationships, and resilient operational frameworks, which contribute to their enduring presence on the exchange. Literature, such as (Kot, 2011), supports this, highlighting that older companies with a prolonged market presence tend to have more stable financial performance and better adaptability to market changes, thus reducing delisting risk. Agency theory suggests that older, well-established companies have mature governance structures that align management’s actions with shareholders’ interests, reducing financial distress and delisting likelihood. Stakeholder theory emphasizes the importance of strong relationships with stakeholders, fostering trust and confidence, which contributes to corporate stability and lower delisting risks. Signaling theory proposes that long-established companies send positive signals to the market about their stability and reliability. A lengthy listing duration indicates that a company has successfully navigated various market conditions, signaling to investors that it is well-managed and capable of sustaining its market presence. Bonding theory posits that companies with a long history on the exchange build strong relationships and reputations, fostering stakeholder loyalty and long-term commitment, which act as safeguards against delisting.
Empirical studies further reinforce this finding. Sanger & Peterson (1990) suggest that older companies benefit from more stable cash flow and diversified operations, enhancing their resilience to market fluctuations. Doidge et al. (2017) note that companies with extended listing durations exhibit lower volatility. Bessler et al. (2022) indicate that company age positively correlates with reduced bankruptcy risks.
Another significant determinant is analyst recommendations, particularly the number of analysts recommending a company’s shares. With a p-value of < 0.001 and an estimated coefficient of -0.16, this factor shows that more analyst recommendations are significantly associated with a lower probability of delisting (see
Table 14). Positive analyst coverage boosts company visibility, investor confidence, and market perception, thus reducing delisting risks (Mehran & Peristiani, 2010). This increased confidence enhances the company’s visibility and attractiveness to investors, thus lowering delisting likelihood. Analysts’ scrutiny holds management accountable, reducing agency costs and delisting risks (Lins et al., 2002).
On the macroeconomic front, the final model identifies five significant macroeconomic predictors of delisting probability: inflation, the repo rate, credit extensions, unemployment rate, and real economic activity (see
Table 14). Compared to the initial model, these factors remained significant, with real economic activity, represented by electricity generation and distribution, emerging as an additional key factor.
The CPI has a p-value of 0.014 and an estimated coefficient of -0.098 (see
Table 14). This suggests that higher inflation rates are linked to a lower probability of delisting. Inflation can drive economic activity, increase nominal revenues, and lessen real debt burdens, contributing to financial stability and supporting better financial planning and corporate governance (Garcia & Liu, 1999).
The repo rate shows a p-value of <0.001 and a coefficient of 0.023 (see
Table 14). Higher interest rates increase the probability of delisting by raising borrowing costs and straining financial resources, impacting strategic decision-making and company performance (J. R. Macey & O’Hara, 2002).
Measured by year-on-year percentage change, credit extensions have a p-value of <0.001 and a coefficient of -0.097. Increased credit availability reduces delisting probability by supporting financial stability and growth, promoting long-term corporate stability.
The unemployment rate in South Africa has a p-value of 0.011 and a coefficient of 0.025 (see
Table 14). Higher unemployment rates increase delisting probability, reflecting broader economic challenges that affect companies and investor confidence.
Measured through year-on-year percentage change in electricity generation and distribution, real economic activity has a p-value of <0.001 and a coefficient of -0.089 (see
Table 14). Higher economic activity reduces delisting probability, fostering corporate stability and investor confidence.
Interestingly, while GDP was not a significant predictor, real economic activity measured through electricity usage was, suggesting it as a more immediate indicator of economic activity within South Africa. Local macroeconomic variables like CPI, interest rates, credit extensions, unemployment rates, and real economic activity are crucial in influencing delisting risks, offering a clearer understanding of delisting decisions within the South African context.
