Unless otherwise indicated, all amounts are in Canadian dollars.

"I am encouraged with our first quarter results with sales at $126.2 million, supported by continued growth in our defence sales which mitigated softness in the civil sector as well as head winds coming from foreign exchange. I am confident that we can deliver stronger throughput as our production system is continuing to adapt to the changes we made over the past year," said Martin Brassard, President and CEO of Héroux-Devtek.

"We continue to see the future with prudent optimism given our diversified product portfolio and the flexibility we can derive from our strong financial position. Once the civil aerospace market recovers, we will be ready to absorb the resulting growth within our current production structure," added Mr. Brassard.

FIRST QUARTER RESULTS

Consolidated sales decreased 1.7% to $126.2 million, from $128.3 million last year. Lower foreign exchange rates, particularly for the U.S. dollar, negatively impacted sales by $9.5 million, or 7.4%, compared to the corresponding quarter in Fiscal 2021.

Excluding the impact of foreign exchange rate fluctuations, defence sales were up 21.5%, while civil sales decreased 19.0%. The increase in defence sales mainly resulted from the ramp-up of deliveries under the Boeing F-18 and Sikorsky CH-53K programs, as well as by higher aftermarket demand. The decrease in civil sales is mainly related to lower demand due to the COVID-19 pandemic, whose impact had not fully materialized in the first quarter of Fiscal 2021.

Gross profit for the quarter grew from $20.5 million last year to $21.6 million, mainly as a result of the positive effect of the Corporation's restructuring initiatives on its cost structure, partially offset by the negative impact of foreign exchange fluctuations. As a percentage of sales, gross profit grew from 16.0% to 17.1%.

Operating income grew to $10.8 million, or 8.6% of sales, compared to $1.4 million, or 1.1% of sales last year, which reflected $6.0 million of restructuring charges. Adjusted EBITDA, which excludes non-recurring items, stood at $20.0 million, or 15.9% of sales, compared with $18.4 million, or 14.3% of sales, a year ago.

Earnings per share grew from a loss of $0.04 last year to earnings of $0.19 in the first quarter this year, as a result of the same factors as those presented above. Adjusted EPS reached $0.19 in the first quarter, up from $0.09 last year.

FINANCIAL POSITION

Cash flows related to operating activities reached $18.2 million in the first quarter, up from $15.5 million last year, mainly as a result of higher adjusted EBITDA.

As at June 30, 2021, net debt stood at $148.0 million, down from $157.5 million as at March 31, 2021. The decrease in net debt during the three-month period is mainly related to cash flow generation net of cash allocated to the Normal Course Issuer Bid.

NORMAL COURSE ISSUER BID

In May 2021, the Corporation announced the approval by the Toronto Stock Exchange of its Normal Course Issuer Bid (NCIB), under which Héroux-Devtek has the right to purchase for cancellation, from May 25,

2021, to May 24, 2022, a maximum of 2,412,279 common shares, representing, as of May 12, 2021, 10% of the public float of 24,122,794 common shares.

As of August 9, 2021, Héroux-Devtek has purchased and cancelled a cumulative 672,827 common shares for a cash consideration of $11.9 million, representing a weighted average price of $17.69 per share.
