I think due to the disclosure of the pricing agreement this is exactly what gives A2 a good bump. Previously there hadn't been any disclosure around the terms, so validation A2 have the bargaining power should reinforce to investors that margins are locked in and if anything will increase. When they referred to increasing scale this might've been hinting at better terms with suppliers.
If you take out the noise SM1 looks pretty attractive given the growth plan is still on track.
