Ulta Beauty (NASDAQ:ULTA) recently shocked investors by reducing its full-year growth expectations. The spa and beauty products retailer said it sees sluggish sales and falling profitability for a second straight year, rather than the modest rebound it had predicted just a few months ago.

In a conference call with analysts, CEO Mary Dillon and her team explained the reasoning behind the downgrade while noting that their positive long-term outlook hasn't changed. Below are a few highlights from that presentation.

A good quarter -- with a big exception

The Ulta Beauty team delivered another quarter of solid top line performance, gross margin expansion and double-digit earnings growth.

The fiscal second quarter wasn't bad. In fact, revenue rose at about the same pace as in previous quarters, with rising customer traffic supporting a 6% increase in comparable-store sales. The expanding store base allowed overall sales to rise 12% compared to 13% last quarter. Profitability was also healthy, with gross profit margin ticking up to 36.4% of sales from 36% a year ago.

Yet executives noted a worsening of demand in the core cosmetics segment that makes up about half of its business and delivers its highest-margin sales. That niche didn't stabilize, as management had predicted it would, but instead fell further into negative territory. "After several years of very strong performance," Dillon said, "growth in the makeup category has been decelerating over the last two years and recently turned negative."

Innovation is to blame

The most recent cycle of innovation has just not driven [new makeup] behaviors, resulting in a soft cycle for the cosmetics category as innovation and newness brought to the market has not driven the expected growth.
-- Dillon

Management noted that Ulta is winning market share across its product niches, including in the core makeup category. However, the latest products released by major makeup brands aren't resonating with customers as strongly as they have in recent years. New launches aren't sparking additional application rituals and techniques, so the overall industry has started declining. Ulta is optimistic that a rebound will eventually occur in this consumer staple niche, but likely not in 2019.

Adjusting expectations

It has become apparent to us that we will not see the improvement we had expected in prestige makeup and we will likely also see moderation in the mass makeup sales trend. As a result, we have lowered our sales and gross margin expectations for the second half of the year.
-- CFO Scott Settersten

Ulta's original 2019 growth outlook assumed rebounding demand in the makeup category during the second half of the year. That boost isn't looking likely, given the current trends, so executives rolled back their guidance. Specifically, the company now sees comps rising by between 4% and 6% for the year rather than the 6% to 7% prior range. Operating margin is now on track to decline for the second straight year rather than rebound slightly.

Part of that earnings shortfall is due to the demand challenges, but the rest is driven by continued aggressive investments in things like store remodels and the build-out of Ulta's e-commerce abilities. Executives see no reason to scale back on these long-term investments during what they believe is just a temporary growth issue for the wider makeup industry.
