Appen’s trading update
On Wednesday 10 May, Appen shares nosedived 28% after flagging a softer-than-expected start to FY23 and guided towards a “materially lower” first half.
The company also announced plans to accelerate cost reduction plans, targeting approximately $36 million in savings in FY23-24. These cost reductions plans would result in one-off costs of approximately $4-5 million.
Appen had $27 million in cash at the end of April but the business was not profitable in FY22 – logging a steep $22.8 million loss compared to a $40.6 million profit in FY21.
One week later, the company announced a $60 million capital raising at a 19.6% discount to its previous close. Appen said the funds would be used to provide “balance sheet flexibility and support general working capital requirements to support Appen’s return to profitability.”
Appen was down as much as 17% on Wednesday, marking another massive win for shorters.

Winners and losers
Winner #1: Vulcan raised $109 million at a 17.2% discount Friday 5 May, which triggered a 16.4% selloff on the day. The decline in short interest may reflect some covering/profit taking.
Winner #2: Best & Less received a lowball takeover offer of $1.89 per share from BB Family International Trust – which already had a 16.45% stake in the company. This offer price was 4% lower than where the stock was trading. Over the next few days, the stock would progressively fall towards the lowball offer price.
Loser #1: Kogan shares rallied as much as 30% between 20 April and 5 May, after a third quarter FY23 trading update noted significantly corrected inventory levels but still-subdued sales activity.
