Growth, as the source summarises it

RSK Group may be growing as it is actively seeking significant funding and pursuing an aggressive acquisition strategy. The company is seeking £500 million in preferred equity to fund its growth initiatives, indicating a substantial investment in its future development. Additionally, RSK Group has recently acquired Australia's largest heritage specialist, expanding its international footprint and capabilities in the environmental consulting sector. The company has also expanded its Australian operations with another acquisition, further demonstrating its commitment to growth in the CleanTech and environmental consulting industries.
