Pulp sales in the period totaled 426 thousand tons, the second highest volume
since the startup of the Puma Unit. Fluff pulp sales were a new record.

Total cash cost per ton, excluding the effects of maintenance shutdown, was
R$3,042/ton in the quarter, decreasing 3% and 6%, respectively, from 3Q22
and 2Q23.

Adjusted EBITDA per ton in the paper and packaging business grew 7% in the
first nine months of 2023 compared to the same period last year.

São Paulo, October 25, 2023 – Klabin, Brazil's largest producer and exporter of
packaging paper and sustainable solutions in paper packaging, the country’s only
producer to offer solutions in hardwood, softwood and fluff pulp, has reported adjusted
EBITDA (Earnings Before Interest, Tax, Depreciation and Amortization) of R$1.352
billion in the third quarter of 2023, an increase of 1% from the previous quarter and
41% lower than in the same period in 2022. In the first nine months of 2023, adjusted
EBITDA/ton from the paper and packaging business was R$1,824 per ton, up 7% from
the same period last year.

Total sales volume (excluding wood) in the third quarter was 967 thousand tons, driven
mainly by the pulp segment, which registered the second highest sales volume since
the operational startup of the Puma Unit in Paraná. This performance was the result of
Klabin’s geographic flexibility and its unique product portfolio, backed by record fluff
sales.

Cash cost, excluding the effects of maintenance shutdown, stood at R$3,042/ton in
3Q23, down 3% year on year and 6% from the previous quarter, reflecting Klabin’s
efforts to pursue increasingly greater efficiency in its operations.
Klabin’s performance in the third quarter of 2023 amid a market scenario that continues
to be challenging underscores the resilience of its integrated, diversified and flexible
business model.
