Abstract We present High-Level Science Products (HLSPs) containing light curves from MIT's Quick-Look Pipeline (QLP) from the second year of Transiting Exoplanet Survey Satellite (TESS’) first Extended Mission (Sectors 40–55; 2021 July–2022 September). In total, 12.2 million per-sector light curves for 5.7 million unique stars were extracted from 10 minutes cadence Full-Frame Images (FFIs) and are made available to the community. As in previous deliveries, QLP HLSPs include both raw and detrended flux time series for all observed stars brighter than TESS magnitude T = 13.5 mag. Starting in Sector 41, QLP also produces light curves for select fainter M dwarfs. QLP has provided the community with one of the largest sources of FFI-extracted light curves to date since the start of the TESS mission.
