Appen Ltd (ASX: APX)
The Appen share price is down 14% to $5.65. This follows weakness in the tech sector, concerns over demand from social media customers, and a broker note out of Citi. The latter has seen the broker warn investors that Appen's first half earnings could fall short of estimates. It also has concerns over management's expectation for a big jump in revenue in the second half.
EML Payments Ltd (ASX: EML)
The EML share price is down 22% to 93 cents. Investors have been selling this payments company's shares following news that the Central Bank of Ireland has not approved the remediation programme for its European operations. The bank identified "shortcomings" in components of the programme, principally the sequencing and approach taken to the risk assessment of its distributors, corporates and customers.
Imugene Limited (ASX: IMU)
The Imugene share price is down 9% to 23.2 cents. This morning this biotech company released its quarterly update and revealed an operating cash outflow of $10.15 million. Though, the company remains in a strong financial position with a cash balance of approximately $100 million.
Nanosonics Ltd (ASX: NAN)
The Nanosonics share price is down 8% to $4.24. This follows the release of the infection prevention company's business update this morning. Although that update revealed sales ahead of consensus estimates, the lack of commentary around costs appears to have spooked investors. There are concerns that the company's margins could be crunched by its sales model transition in North America.
