Buenos Aires, May 8, 2018 – Loma Negra, (NYSE: LOMA; BYMA: LOMA), (“Loma Negra” or the “Company”), the leading cement producer in Argentina, today announced results for the three-month period ended March 31, 2018.

1Q18 Key Highlights

§	Cement, masonry & lime sales volume in Argentina up 9.5% YoY reflecting continued market growth

§	Net revenue up 41.6% YoY to Ps.4,534 million (US$230 million) driven by volume and favourable price environment.

§	Adjusted EBITDA up 40.6% YoY to Ps.1,166 million (US$59 million). Adjusted EBITDA margin of 25.7%, remaining almost flat.

§	The Cement, Masonry, and Lime segment in Argentina posted a 52.1% YoY increase in Adjusted EBITDA with Adjusted EBITDA margin expanding 207 basis points to 28.7%

§	Net Debt /LTM Adjusted EBITDA ratio of 0.53x from 1.48x in 1Q17 and 0.30x in 4Q17

Commenting on the financial and operating performance for the first quarter of 2018, Sergio Faifman, Loma Negra’s Chief Executive Officer, noted: "We reported solid results in the first quarter, with volume and revenue growth principally driven by continued momentum in public infrastructure and private construction in Argentina reflecting ongoing economic growth.”

“Loma Negra’s cement, masonry and lime segment in Argentina, our core business, posted a 9.5% year-on-year increase in volumes during 1Q18. Volume growth, along with positive price environment resulted in Adjusted EBITDA for this segment increasing 52% during the period achieving a margin expansion of 207 basis points. On a consolidated basis, Consolidated Adjusted EBITDA margin remains almost unchanged.”

“For the remainder of the year, we are confident that we will continue to see healthy dynamics in our markets with increasing demand for cement and concrete, although at slower rates following the significant recovery experienced in the prior year, supporting our expansion plans. We are also making headway in the expansion of our L’Amali plant that will add to capacity as well as drive profitability gains.”

Railroad	MM Tn	1.17	1.23	-4.9%
Aggregates	MM Tn	0.29	0.23	22.9%

Supported by continued momentum in private construction and infrastructure and reflecting the Company’s balanced approach of growing the topline while preserving gross margins, sales volumes of cement, masonry and lime in Argentina were up 9.5% YoY reaching 1.58 million tons in 1Q18. Sales volumes in Paraguay fell 5.2% in the period to 0.14 million tons compared with an 8% decline for the industry, due to a slow start to the year. As a result, consolidated total sales volumes of cement, masonry and lime for the quarter increased 8.1% YoY to 1.72 million tons.

Concrete volumes in Argentina, increased 44.8% YoY to 0.25 million m³driven by continued robust growth in public infrastructure in the Company’s markets - the city of Buenos Aires and Greater Buenos Aires and the city of Rosario, province of Santa Fe.

Aggregate volumes were up 22.9% YoY to 0.29 million tons, benefiting from strong demand. The new crusher is already mounted and began operations in April which contributed to alleviate capacity constraints and is anticipated to double production capacity of aggregates once it’s fully operational. By contrast, sales volumes at Loma Negra’s railroad subidiary, Ferrosur, declined 4.9% to 1.17 million tons mostly due to lower transported volumes of third-party aggregates.

Net Revenues

Net revenue increased 41.6% to Ps.4,534 million in 1Q18, from Ps.3,202 million in the year-ago quarter, principally reflecting strong growth in Argentina – mainly in the Cement, masonry and lime segment and the Concrete segment.

Cement, masonry and lime revenues in Argentina were up 41.1% YoY, to Ps.3,400 million driven by both higher volumes and price increases. Revenues in Paraguay rose 23.1%, reaching Ps.346 million in the quarter as the 5.2% YoY decline in volume was more than compensated by the depreciation of the Argentine peso.

Concrete revenues in Argentina, rose 96.5% YoY to Ps.707 million reflecting volume growth and increased prices. In addition, Railroad revenues increased 22.9% to Ps.441 million despite lower volumes, while Aggregate revenues were up 31.3% reaching Ps.68 million during the period.

Cost of sales rose 43.1% YoY to Ps.3,233 million in 1Q18, as a result of cost inflation, greater sales volume, and a higher share of Concrete sales. Cost of sales in the quarter was also impacted by a temporary increase in supply costs.

As a result, Gross profit increased 38.0% YoY reaching Ps.1,301 million in 1Q18 from Ps.943 million in 1Q17, with gross margin contracting 74 basis points YoY to 28.7%. While Gross profit margin in the Cement, masonry and lime segment in Argentina increased 221 basis points in the period, this improvement was more than offset mostly by robust growth in the lower-margin Concrete segment and lower transported volumes in the Railroad segment.

Selling and Administrative Expenses

Selling and administrative expenses (SG&A) in the first quarter of 2018 rose 21.7% YoY in absolute values to Ps.327 million, from Ps.269 million in 1Q17. As a percentage of revenues, SG&A declined 118 basis points to 7.2% in 1Q18 from 8.4% in the year-ago period mainly driven by higher cost dilution along with a reduction in the effective sales tax rate.

Adjusted EBITDA & Margin

Table 4: Adjusted EBITDA Reconciliation & Margin
(amounts expressed in millions of pesos, unless otherwise noted)
	Three-months ended March 31,
	2018	2017	% Change
Adjusted EBITDA reconciliation:
Net profit	549	399	37.4%
(+) Financial interest, net	15	114	-86.8%
(+) Income tax expense	213	184	15.7%
(+) Depreciation and amortization	189	155	21.5%
(+) Exchange rate differences	109	(87)	n/a
(+) Other financial expenses, net	26	24	11.9%
(+) Tax on debits and credits to bank accounts	65	40	62.1%
Adjusted EBITDA	1,166	829	40.6%
Adjusted EBITDA Margin	25.7%	25.9%	-18 bps

Adjusted EBITDA increased 40.6% year-over-year in 1Q18 to Ps.1,166 million, driven principally by continued growth in volumes and prices.

Adjusted EBITDA Margin, in turn, showed a slight decline of 18 basis points to 25.7%, from 25.9% in 1Q17, reflecting the strong growth of Concrete revenues during the period.

The Cement segment in Argentina, which represented 84% of the consolidated adjusted EBITDA in 1Q18, reported a 52.1% YoY increase in Adjusted EBITDA reaching Ps.975 million with Adjusted EBITDA margin expanding by 207 basis points during the period.

Adjusted EBITDA for the Cement segment in Paraguay was up 22.9% YoY, to Ps.150 million, with Adjusted EBITDA margin relatively flat at 43.4%. In addition, while the Concrete segment posted 19.3% increase in Adjusted EBITDA reaching Ps.15 million, the margin contracted 138 basis points mostly as a result of a temporary increase in the supply cost of raw materials.

By contrast, Adjusted EBITDA for the Railroad segment declined 46.4% to Ps.22 million in 1Q18, with Adjusted EBITDA margin contracting to 4.9% from 11.3% in the year-ago quarter reflecting lower dilution of fixed costs given a decline in transported volumes of aggregates.

Finance Costs, Net

During 1Q18, total finance costs, net increased by 197.7% YoY, or Ps.100 million, reaching a net cost of Ps.151 million, mainly due to foreign exchange differences.

The Company reported a foreign exchange loss of Ps.109 million in 1Q18, as a result of the 7.3% peso depreciation as compared to an Ps.87 million gain in 1Q17 when the peso appreciated 3.0%.

Financial income, in turn increased by Ps.104 million reflecting a higher cash balance, while financial expenses rose by Ps.8 million.

Net Profit and Net Profit Attributable to Owners of the Company

For 1Q18, Loma Negra reported Net Profit of Ps.549 million, up 37.4% from Ps.399 million in the year-ago period. The effective tax rate declined to 28% in 1Q18 from 32% in 1Q17, as a result of the adjustment in deferred taxes in Argentina from the recent Tax Reform which reduced the income tax rate from 35% to 30% in 2018 and 2019, and to 25% thereafter.

Net Profit Attributable to Owners of the Company for the quarter increased 48.6% YoY, or Ps.172 million, to Ps.526 million. During 1Q18, the Company reported earnings per common share of Ps.0.88 and earnings per ADR of Ps.4.41, compared with earnings per share of Ps.0.63 and earnings per ADR of Ps.3.13 in 1Q17.

Definitions

Adjusted EBITDA is calculated as net profit plus financial interest, net plus income tax expense plus depreciation and amortization plus exchange rate differences plus other financial expenses, net plus tax on debits and credits to bank accounts. Loma Negra believes that excluding tax on debits and credits to bank accounts from its calculation of Adjusted EBITDA is a better measure of operating performance when compared to other international players.

Net Debt is calculated as borrowings less cash and cash equivalents.
