75 words by Mike Chang

In the news release announcing his departure as CEO of Alpha & Omega Semiconductor Ltd., Mike Chang received praise.

In the announcement of the leadership change, Mike Chang said 75 words.

“With great confidence and pleasure”

Mike Chang stated: “It has been a tremendous privilege to serve as Chief Executive Officer of AOS, and I am very proud of the many successes and accomplishments since the inception of our company. It is with great confidence and pleasure that I now turn the chief executive position to Stephen, who has already demonstrated his leadership skills and business acumen since his appointment as AOS’s President two years ago, leading AOS to achieve record revenues and profitability.”

Over the past 12 months, 27% of all outgoing CEOs remained silent in the departure announcement, according to data compiled by exechange. Departing CEOs who did make a statement said an average of 109 words. The longest statement was 382 words. The shortest statement was 23 words. Leadership transitions in which departing CEOs provide conspicuously short, excessively long or no explanations for their move are statistically associated with elevated pressure and show an increased incidence of Push-out Scores above the critical threshold of 5. In contrast, leadership changes are statistically associated with low pressure when departing CEOs speak more about their successors than their successes.

32% of CEOs are forced out or fired

When CEO departures are announced, exechange determines the Push-out Score on a scale of 0 to 10 to assess how likely it is that the chief executive was pushed out or felt pressure to leave the position, with 0 being most likely a voluntary move and 10 being most likely a forced exit. Anything over a 5 indicates that there are valid reasons to believe an executive may have been pushed out.

Of the 324 CEO departures in the Russell 3000 Index evaluated over the past 12 months (December 8, 2021, to December 7, 2022), the average Push-out Score was 5.6, according to exechange data. References to conduct issues, disagreements and irregularities lead to the highest Push-out Scores. When time with family, performance issues or personal reasons were cited as departure reasons, the average Push-out Scores were also significantly elevated.

Around 32% of the CEO departure events from the past 12 months received Push-out Scores of 8 or higher.

In other words, in the past 12 months, three in 10 departing CEOs were forced out or fired.

Pressure in the information technology sector well above the critical threshold

Some industries are under generally higher pressure than others, and CEOs are feeling the strain. In the past 12 months, the communication, health care and consumer staples sectors showed the highest average Push-out Scores. By contrast, pressure on CEOs was lowest in the real estate, financials and industrials sectors, as measured by average Push-out Scores.

In the information technology sector, which includes Alpha & Omega Semiconductor Ltd., the average Push-out Score over the past 12 months was 6.2, which is well above the critical threshold of 5.

In the information technology sector, 19 exiting CEOs received Push-out Scores of 8 or higher over the past 12 months, indicating that they were most likely forced out or faced strong pressure to step down.
