1H2019 Results Highlights

•

Net revenues in 1H19 decreased 27%, from R$709 million in 1H18 to R$518 million in 1H19. The 41% decrease in net revenues from Public Collection was as a result of scope and price reductions in some of our public collection contracts. This negative impact reflected increased competition in bidding processes for renewal of public collection contracts and aggressive price discounting, resulting in the loss of contracts and the renewal of others at lower prices and margins. In particular, the re-zoning of São Paulo into six separate parcels for urban cleaning in June 2018 had a significant negative impact as it resulted in material price and scope reductions under the extended temporary contract under which we provided services.

•

Net Income in the first half of 2019 was a loss of R$93 million compared to a loss of R$125 million in the same period of last year. This decrease was attributable to our losses in Public Collection contract services.

•

Adjusted EBITDA decreased 50% to R$91 million in 1H19, compared to R$182 million in 1H18 with a margin of 18% in 1H19 compared to 26% in 1H18. This reflects, among other factors, increased competition in bidding for new public collection contracts.

First Half of 2018 and 2019 Results

Revenues by Segment


Net Revenues (in R$ million)	1H2018		1H2019		Chg.
Collection & Cleaning Services		451		288		-36%
Public		404		237		-41%
C&I		47		51		9%
Landfills		218		194		-11%
Environmental Services		13		1		-92%
Valuey Recovery		27		35		30%
Total		709		518		-27%

Revenues in 1H19 were R$518 million, a 27% decrease in comparison with net revenues of R$709 million in 1H18.

Revenue from Collection & Cleaning Services decreased by R$163 million or 36% mainly as a result of scope and price reductions in some of our public collection contracts starting in the second quarter of 2018. This negative impact reflected increased competition in bidding processes for renewal of public collection contracts and aggressive price discount, resulting in the loss of contracts and the renewal of others at lower prices and margins.

Revenue from our Landfills segment decreased R$24 million or 11%, reflecting the end of our Catanduva landfill operational contract and volume losses at our Itapevi landfill, where we limited current volume while we invested to increase future capacity, as well as at our Tremembé and Feira de Santana landfills.

Revenue from our Environmental Services segment decreased by R$12 million or 92% due to a strategic decision to discontinuation these kinds of services.

Revenue from our Value Recovery segment increased by R$8 million or 30% primarily due to our new RDF plant (D-MRF) (refused-derived fuel) in Paulinia becoming operational.

Operating Costs

Cost of services decreased R$96 million or 19%, from R$495 million in 1H18 to R$399 million in 1H19.

Adjusted Gross Margin, which we calculate as Net Revenues minus Adjusted Operating Costs divided by Net Revenues, in 1H19 dropped 3 percentage points from 85% to 82%.

Operating Expenses

Operating expenses decreased R$56 million or 35%, from R$162 million in 1H18 to R$106 million in 1H19.

Excluding non-recurring events detailed in Table A annexed hereto, Adjusted Operating Expenses decreased 11%, from R$103 million in the first half of 2018 to R$92 million in the first half of 2019.

Adjusted EBITDA and Net Result

For those reasons identified above, our Net Result in 1H19 was a loss of R$93 million compared to a loss of R$125 million in 1H18.

Adjusted EBITDA decreased 35% to R$91 million in the first half of 2019, primarily as a result of the loss of revenue. Adjusted EBITDA Margin, which we calculate as Adjusted EBITDA divided by Net Revenues, was 18% in the first half of 2019, down from 26% in 1H18.

2019 Full-Year Outlook

We currently anticipate that revenues for the full year 2019 will decrease approximately 30% compared with 2018 and that Adjusted EBTDA margins will be around 20% for 2019. Severance payments for the employees of the terminated public collection contracts and the restructuring of our overheads will be a substantial burden on the results for 2019.

We remain confident that Estre is operationally well-positioned to succeed as a landfill company in the waste management industry in Brazil. There is a long runway of underserved demand and we believe we are uniquely positioned to service that demand through our culture of compliance and our history of operational excellence.

Financially our future depends heavily on our ability to sell various operational parts of our company to create additional liquidity to overcome our present liquidity bottlenecks and also heavily depends on the successful renegotiations of our outstanding debts. As previous reported, we have hired Alvarez & Marsal to assist the corporation in these negotiations.
