Best ASX growth shares to buy now?

Investors who want to build long-term wealth should consider buying and holding the following 2 ASX growth stocks because both businesses have scalable business models and strong long-term earnings growth opportunities.

Sigma Healthcare Limited (ASX: SIG) 

Sigma Healthcare Limited is one of the strongest ASX growth stocks to buy and hold because it is bound to benefit a lot from fast international expansion supported by favourable healthcare industry trends.
The company in 1H26 reported very strong financial performance as revenue rose 14.9% year-on-year to $5.5 billion while normalised EBIT increased 18.7% to $582.9 million and normalised NPAT climbed 19.2% to $392.0 million compared with the prior corresponding period.

Operational efficiency also improved during the half because EBIT margins expanded by 34 basis points to 10.6% while EPS grew 19.4% due to scale benefits and disciplined cost management.
Chemist Warehouse branded stores in Australia recorded sales growth of 17.2% during the period while like-for-like sales increased 15% which highlights the strong demand for the company’s value-focused pharmacy retail model across the domestic market.

International operations also showed strong momentum as network sales increased 24.5% and the company expanded its footprint to 97 stores with additional store openings planned for 2H26.
The owned and exclusive label business is a major strength for Sigma because sales rose 15.7% and more than 400 new products were launched during 1H26. Chemist Warehouse branded store sales rose 16.6% during the first seven weeks of the second half.

The company by FY29 aims to achieve around $100 million per annum in synergies. Sigma also maintains a conservative balance sheet with net debt to EBITDA of only 0.6x while strong operating cash flows can support future growth initiatives and expansion opportunities without heavy financial pressure.

Life360, Inc. (ASX: 360) 

Life360, Inc is one of the most attractive ASX growth stocks to buy and hold because the company has a combination of rapid user expansion with higher monetisation and a massive long-term opportunity in the global family safety market.

The stock is currently down nearly 44% year-to-date which has pushed valuation levels into a much more attractive range while the current market capitalisation is $4.52 billion.

Life360 during Q1’26 reported revenue of US$143.1 million which represented a strong 38% year-on-year increase while adjusted EBITDA rose to US$17.1 million with a 12% margin.
The platform now has around 97.8 million monthly active users across more than 180 countries while paying circles have almost reached 3 million.

Management also stated that international markets are significantly underpenetrated especially across Europe and Rest of World regions which are still at an early stage of adoption and could provide a very large runway for future subscriber and member growth.
The company is rapidly expanding across additional monetisation categories such as advertising, pet tracking, digital safety and financial services while the recently announced Uber integration may further improve the family super-app ecosystem.

Another major positive development was the announcement of a US$225 million multi-year share repurchase program because it reflects management’s confidence in the durability of the long-term cash generation potential and balance sheet strength after twelve straight quarters of positive operating cash flow.
