text: On 25 May 2016, CSKA Sofia won the 2015–16 Bulgarian Cup, becoming the first third-division club to record such an achievement. In the final, CSKA defeated Montana 1–0 to lift the cup for the 20th time in club history.
  On 27 May 2016, the legal firm that represented PFC Chavdar Etropole, "PFC Chavdar EAD", was renamed to "PFC CSKA-1948 AD". On 6 June 2016, the legal firm which representedb Litex Lovech, "PFC Litex-Lovech AD", was renamed to "PFC CSKA-Sofia EAD", in order for the club to use PFC Litex Lovech's professional license to apply for the reformed First League, with "PFC CSKA-1948 AD" being written in as its owner. The shift was made because the old legal firm, "PFC CSKA AD", was not issued a professional license, and later went bankrupted and ceased operations as of 9 September 2016. Litex Lovech later began playing in the Third League, taking the place of Botev Lukovit.
  Following a series of unfavourable results in the championship, Hristo Yanev resigned as head coach. The following week, the son of former Romanian football legend Anghel Iordănescu, Edward Iordănescu, was appointed as head coach. However, on 27 November, following a 1–1 home draw against Vereya, he resigned as head coach.
  In September 2017, the club officially announced a sponsorship with Mtel, the largest telecommunications company in Bulgaria. A sponsorship contract was also signed with Bulgarian online gambling company WinBet.
