The statement is directly confirmed by a credible source (Reuters), which reports that the HCOB Flash France Composite PMI Output Index fell to 48.4 in September, explicitly 'marking a five-month low'. The specific PMI figures are corroborated by another source (Trading Economics). While one source (CNBC) reports different figures and an 'eight-month low', it is an outlier compared to the corroborating evidence.
