BRAMPTON, ONT. --  

Canada's largest grocer believes it will see "financial pressure" in the future as customers' shopping habits change and costs rise during the COVID-19 pandemic.

Loblaw Companies Ltd. saw a recent spike in sales much like Canada's other large grocers -- Metro Inc. and Empire Co. Ltd. -- as customers stockpiled food in preparation to spend more time at home and eat out less often.

The company's first quarter "was a tale of 14 days," president Sarah Davis told a conference call with analysts Wednesday after Loblaw, which owns Loblaws grocery stores and the Shoppers Drug Mart chain, , released its quarterly earnings report.

Loblaw saw "a rush to retail" after the coronavirus was declared a pandemic, she said, noting customer count and basket size quadrupled and e-commerce traffic tripled.

Chief financial officer Darren Myers said during the two weeks ended March 21 that Loblaw saw grocery store sales grow about 44 per cent. Pharmacy sales grew 26 per cent, while pharmacy front-store sales jumped 42 per cent.

Loblaw estimates the pandemic generated an incremental $751 million in revenue during the quarter, he said.

The positives were partially offset by increased operating costs related to the coronavirus, which started ramping up near the end of the first quarter.

"It is very difficult to predict how sales will evolve," said Myers, noting the company expects, for example, possible decreases in discretionary spend categories.

"Since the beginning of the second quarter, we've experienced a pronounced change in the trajectory of our sales."

During the first five weeks of the second quarter, food sales grew about 10 per cent, he said, but drug sales declined about six per cent.

The company is also seeing declines in its clothing, general merchandise and beauty categories, which are "all relatively high-margin parts of our business," Davis said.

General merchandise and apparel were negative in the last two weeks of the first quarter, she said, and continue to be so in most weeks of the second quarter to date with apparel experiencing a larger drop.

Those drops comes as COVID-related costs continue.

Loblaw is spending about $90 million every four weeks on efforts to keep its stores safe for customers and employees, on temporary wage increases and other measures, Myers said.

"It's incredibly hard for us to predict the future after all this," he said when asked how much of those cleaning, extra staffing hours and other costs Loblaw expects to become embedded permanently in its operations.

"I would say these are temporary costs right now that we expect to continue through the pandemic, but it's too difficult for any of us to predict what happens afterwards."Loblaw expects those costs to hit more heavily in its second quarter.

A bright spot for the company has been a tripling of demand for its e-commerce services, which includes both store pickup and home delivery options. The company's online apparel, beauty and pharmacy businesses are all up, she said.

Loblaw did not expect this level of demand for two or three years, said Davis.

The company worked to scale its ability to fulfil so many more orders by enhancing its technology, increasing labour hours and more.

Customers did experience delays due to the increased demand, she said, especially in major centres.

The average wait time is now six days, she said, with plans to get back to a daily turnaround time.

"We've been adding capacity as fast as we can in order to get back to that."

While it's "difficult to anticipate precisely how our business will change in any emerging new normal," executive chairman Galen Weston said the company believes "that online grocery shopping will retain a significant proportion of the current sales penetration."

He also noted more customers responding to digital promotion strategies and adopting digital health-care services as possible customer trends Loblaw expects will accelerate substantially from the time before the pandemic.

The company reported a first-quarter profit attributable to common shareholders of $240 million or 66 cents per share for the 12-week period ended March 21. That compared with a profit of $198 million or 53 cents per share in the same quarter last year.

Revenue totalled $11.8 billion, up from nearly $10.7 billion in the first quarter of 2019.

Food retail same-stores sales rose 9.6 per cent, while drug retail same-store sales climbed 10.7 per cent as pharmacy same-store sales rose 10.6 per cent and front store same-store sales gained 10.7 per cent.

On an adjusted basis, Loblaw said it earned $352 million or 97 cents per share, up from $290 million or 78 cents per share a year earlier.
