Orbiting a G-type star every $\\sim100$ days, the Saturn-mass exoplanet TOI-199 b ($T_{\\rm eq}=350$ K) is one of the most favorable low-temperature gas giants for atmospheric study. Here, we present its transmission spectrum from a single transit observed with JWST's NIRSpec G395M mode. Despite lower-than-nominal precision due to a pointing misalignment, the spectrum reveals the presence of CH$_4$ (Bayes factor of $\\sim$700 in a cloudy atmosphere), corresponding to a metallicity of ","authors_text":"Aaron Bello-Arufe, Armen Tokadjian, David K.
