ASX shares with long-term growth plans may be some of the most attractive investments on the ASX because they could become much larger during that time.

Some companies are tapping into long-term trends like ageing demographics, while others may be able to lengthen their growth runways by expanding overseas.

The Wilson Asset Management (WAM) team have revealed some of the most compelling businesses in the WAM Capital Limited (ASX: WAM) portfolio, which are expected to grow significantly in the coming years.   

Some of the next ASX blue-chip shares may be up-and-coming companies like the ones below.

Tuas Ltd (ASX: TUA)

The first stock I'll talk about is Tuas, a telco that owns and operates a mobile network and provides telecommunication services in Singapore.

A few years ago, the Singapore-based business was spun out of TPG Telecom Ltd (ASX: TPG) and has been rapidly growing ever since.

WAM noted that the recent FY24 result revealed mobile subscriptions in Singapore continued to surpass analyst expectations.

In FY24, Tuas reported revenue increased 36% year over year thanks to a 28.6% increase in subscribers to 1.05 million. The telco revealed that operating profit (EBITDA) increased 60% year over year, thanks to a rise in the EBITDA margin from 36% in FY23 to 42% in FY24. WAM was pleased to see that operating margins continued to improve.

The investment team explained why they are confident about the ASX share's future:

Tuas is a significant disrupter to the telecommunications market, and we view that recent launch of broadband and enterprise services as increasing Tuas' total addressable market, and in time see its potential entry into Malaysia or Indonesia.

Regis Healthcare Ltd (ASX: REG)

The other ASX share that WAM highlighted is Regis Healthcare, a residential aged care specialist and retirement village provider.

The fund manager noted the company had a positive September after the government announced an update to aged care funding, which will see increased funding for operators in the industry.

WAM believes the higher level of funding will "encourage the development of more beds and provide greater subsidies per patient."

It was highlighted by Wilson Asset Management that the government plans to review the sector's accommodation supplement and pricing which have "fallen short of medium house price growth."

Regis also recently announced that it is acquiring two high-quality residential aged care facilities, which is part of the ASX share's strategy to broaden its footprint in premium homes.

WAM concluded its positive view of the aged care operator with the following:

We believe Regis Healthcare is the best placed pure-play listed aged care provider in Australia and it should continue benefiting from an ageing population, additional government funding and strategic growth initiatives.
