DigiCo Infrastructure REIT (ASX: DGT)
According to a note out of Bell Potter, its analysts have retained their buy rating on this data centre company's shares with a trimmed price target of $3.35. The broker highlights that DigiCo announced its FY 2026 result last week with its underlying EBITDA of $126.6 million slightly above expectations. And while guidance for FY 2027 EBITDA came in below estimates, it believes a material capex spend and customer letters of intent points to earnings ramping up in FY 2028 as billing comes on line. It believes this should support a growing dividend. In addition, with its shares still trading at a deep discount to their net tangible assets, Bell Potter sees a lot of value in them. The DigiCo share price ended the week at $2.53.
Goodman Group (ASX: GMG)
A note out of Macquarie reveals that its analysts have retained their outperform rating and $35.40 price target on this industrial property company's shares. This follows the release of an FY 2026 result that revealed operating earnings marginally ahead of consensus estimates. Once again, while its guidance for FY 2027 was a touch short of expectations, the broker appears confident it can outperform this and is expecting a double-digit three-year earnings compound annual growth rate. So, with its shares trading at a discount to its long-run PE ratio, Macquarie thinks now could be the time to buy. The Goodman share price was fetching $27.27 at Friday's close.
Megaport Ltd (ASX: MP1)
Analysts at Morgans have upgraded this network services company's shares to a buy rating with a $25.00 price target. According to the note, Megaport delivered both FY 2026 earnings and FY 2027 guidance that were above market expectations. This reflects record network and compute growth. And while there are minor balance sheet concerns, Morgans believes the company will end FY 2027 with surplus liquidity of nearly $600 million. Outside this, it highlights that deals already contracted suggest that EBITDA will lift 3 times in FY 2027 and then more than double in FY 2028. The Megaport share price ended the week at $18.38.
