@hainc capital allocation is always an interesting discussion, because I think we can all agree that it is the most important job a management team has yet we can't assess how well they have done until many years down the track. For LBL in particular I would rank your five options as 5,1,3,4,2 (debt would be higher but for LBL the debt on the balance sheet is their lease obligations).
However we know LBL has handbrakes on their organic re-investment, primarily access to skilled labour. There is no point bringing on new customers or expanding your factories if you can't find the employees to perform the work. Because of that, I think M&A takes on a heightened importance because it would be unlikely to see LBL organically expand into a new geography given the time required to scale up their employee base. We have seen this as they have acquired in Vic, Qld, WA and soon to be US rather than choosing to grow organically. SA was an organic expansion many years ago, but that had the beneficiary of being close to a key customer who underpinned the new factory.
So far I think LBL's M&A track record has been good, though Gateway will be the first real test given the size and the minority interest. Having spoken to management they raved about the Gateway business and team and strongly believe in the synergies they can drive for both businesses.
Looking past LBL and talking capital allocation in general although it can be hard to assess how today's capital allocation will be viewed in the future, I am always pleased to speak to management teams who at least approach it thoughtfully. I remember talking to Vance at XRF many years ago when they were expanding into Europe through their German office and it was an insightful conversation on how they were measuring/forecasting the operating losses of the segment and assessing that against the projected steady state operating profits. From memory the office had cumulative operating losses of $3-4m, and in FY22 reported a profit before tax of $450k. Unfortunately we didn't get the profit explicitly broken out in FY23, though revenue grew from $5.5m to $7.3m so it likely did a profit before tax of $1-2m and would now be generating a very tidy return on upfront invested capital.
However not all management teams are as thoughtful if you push them on the returns on capital of loss making segments or ventures. They can usually tell you what they expect a business to earn as it scales, but very few assess that against the dollars being invested to achieve that, and even worse you see a lot of sunk cost fallacies where management teams will continue to proceed with uneconomical projects because they have already invested significant money into it.
