Issue rendering semi-transparent additive particles on transparent

I’m having an issue involving rendering a scene with additive particles on a transparent background. When I render on a solid black background it works as it does in the viewport. When I switch the film to transparent, the viewport looks fine but the render comes out completely transparent. Here’s my node setup for the additive particles: Anyone know what’s causing this?
