Megaport (ASX:MP1) retail raise closes 105% subscribed as the AI dilution debate settles

Retail take-up above entitlement is a rare vote of confidence in the AI pivot

Megaport (ASX:MP1) has closed the retail leg of its A$827m entitlement offer with the kind of result that quietly settles an argument. The retail component raised A$308m at A$14.30 per new share, and applications came in at roughly A$323m including the top up facility. That is a take-up rate of about 105%.

For a raise this large, that number matters more than it looks. Retail shareholders had every reason to sit this one out. It is Megaport’s second major capital raise in about 18 months, dilutes the register by roughly 32%, and lands at a 13.9% discount to the pre-announcement close.

Instead, retail leaned in. Applications under the top up facility ran hot enough that Megaport had to scale them back to about 81% of what was requested, and refund around A$14m.

Existing shareholders have looked at the four AI contracts worth A$458.9m, the US$252m GPU Pool commitment, and the pro forma A$662.9m group ARR, and decided the growth story is worth another cheque. That is not proof the strategy works, but it removes the funding overhang that has weighed on this stock since early June.

The 105% take-up is the real signal, not the headline dollar figure

Retail entitlement offers rarely clear above 100% when the stock is trading near the offer price and the dilution is material. When they do, it tells you something about how the register reads the pipeline.

Of the A$308m raised, about A$246m came from shareholders taking up their base entitlement and a further A$77m came through the top up facility. A meaningful portion of the retail base not only participated, but actively asked for more stock than they were entitled to.

In our view, that is the most useful data point in the announcement. The institutional leg was already 99% subscribed. Retail conviction at 105% is the confirmation that both ends of the register have accepted the AI compute pivot as the story from here.

The funding question is now closed. The execution question is wide open

With the retail leg settled, Megaport has the full A$827m in hand. That covers the A$369.5m of capex tied to the four new AI contracts, the A$350m GPU Pool commitment, and leaves a buffer for the debt-funded expansion CFO Leticia Dorman flagged in June.

Megaport is now on the hook for utilisation risk on the GPU Pool for the first time, with management guiding to a 16 to 22 month payback at optimal usage. The four contracted deals only start generating revenue from 2027.

Our concern is timing. Between now and when those contracts ramp, the market will judge Megaport on GPU Pool utilisation and quarterly Compute ARR growth. Any slip on those data points and the dilution argument comes straight back.

The Investors Takeaway for Megaport

With retail closing at 105% take-up, Megaport arguably has the strongest shareholder mandate it has ever had to run a capital-heavy AI infrastructure strategy. The register has voted twice inside 18 months to back the pivot, and the second vote came at a materially larger cheque.

From here, the debate moves off funding and onto execution. GPU Pool utilisation and whether Compute ARR continues to compound will drive the stock through the second half of 2026. Our previous coverage of the June raise walked through the strategic logic in detail at stocksdownunder.
