3-Statement LBO Stub Period Adjustment

How would you adjust a 3-statement LBO (including B/S) for a mid-year transaction? 

Let's assume:

• Fiscal year: Jan-25 to Dec-25
• Transaction date: Jun-25
• Currently the model is an annual model (i.e. FY24 and FY25)

Would you:

• Roll forward the Dec-24 B/S to Jun-25 by essentially multiplying all cashflows by 50% e.g.:
  • Only account for 50% of Net Income
  • Assume only 50% of investments (e.g. Capex, NWC changes etc.) occur
  • Only 50% of D&A occurs
  • i.e. only 50% of the net cash generated
• Use the mid-year Jun-25 B/S to transact-off (i.e. for EV - EqV Bridge, S&U)
• Adjust the mid-year Jun-25 B/S for LBO impacts to get a PF Jun-25 B/S (e.g. debt refinancing, goodwill, equity write-off, capitalised financing fees etc.)
• Roll forward the PF Jun-25 B/S to Dec-25
• Resume annual model

How would you adjust the debt schedules? Would you:

• Assuming transaction mid-year at Jun-25, only 50% of the annual debt amortisation and interest expense would be accounted for?

For returns analysis, that's pretty clear to me. 

Any guidance would be much appreciated! Thanks!
