Will GPC report material one-time charges in 2026 beyond the disclosed $225-250M transformation costs?

Q1 delivered the first post-announcement print without a kitchen-sink escalation. The $59M restructuring is inside the $225-250M transformation framework and $75M total pretax includes separation-related costs that also fall inside the ongoing program. This is important because the Q4 2025 'kitchen-sink' thesis predicted continued cleanup charges — Q1 2026 rejects that pattern. Three quarters remain, during which separation execution, potential impairments, or legal/settlement charges could still surface. But the first quarter's cleanliness materially reduces the prior (0.55). Downward adjustment to ~0.40.

Q1 was clean on the one-time-charge axis — restructuring inside plan, no fresh impairments, pension termination already in 2025. However, the threshold is >$50M pretax in any single quarter across Q2-Q4 2026, and material items can emerge: separation-related legal/banking/professional fees (which management explicitly noted are NOT in the $100-150M dis-synergy/stand-alone range), further First Brands reserve adjustments, potential Iran-related demand/inventory write-downs, and restructuring 'true-ups.' Separation mechanics typically produce one-time costs in the quarters closest to the actual separation (Q1 2027). Slight downward revision from 0.55 to 0.43 reflecting Q1 clean print but preserving separation-execution risk.

The strongest signal from Q1 2026 is what DID NOT happen: no new impairments, no new legal reserves, no pension true-ups, no First Brands re-expansion. Only the disclosed transformation program is driving one-time costs. Management's language has shifted from 'kitchen-sink' framing to disciplined execution within plan. Three quarters remain but the absence of new items after nearly five months since Q4 2025 argues the charges were genuinely one-time. Probability drops below 0.40. Main upside risk: separation legal/banking fees land in a single quarter above $50M, which management explicitly flagged as excluded from the $100-150M range.

Q1 2026 print was clean: restructuring inside guidance, no new impairments. This meaningfully reduces the Fugazi Filter's kitchen-sink thesis. However, the $50M pretax threshold is easy to hit if any single quarter sees concentrated separation expenses. With 3 quarters of disclosure remaining and separation execution intensifying into 2027 completion, odds of at least one $50M+ one-off surfacing remain meaningful. Downward from 0.55 to 0.42.

The kitchen-sink narrative was tested in Q1 and lost evidence. The Q1 $75M pretax is disclosed inside the $225-250M transformation envelope. Separation legal/banking/advisor fees are the remaining lumpy-quarter risk. Three quarters to resolution — probability mechanically decays as clean quarters accumulate. Lowering to 0.40.

Q1's absence of new one-time items is the material signal. Q2's $10-20M Iran overlay is already in guidance and not a one-time item. Separation execution could generate lumpy advisor/legal fees in Q3/Q4. Balance of evidence favors NO but with meaningful residual risk, so 0.41.

Q1 was clean. But separation costs in future quarters could easily exceed $50M in any single quarter. Lean below 0.50.

No fresh kitchen-sink items in Q1 reduces probability. But separation legal/banking fees remain a credible lumpy risk. 0.41.

Q1 clean but separation-execution quarters (Q3/Q4 2026 into Q1 2027) could still generate >$50M one-time charges. 0.42.
