The food and drug retail industry is large and dynamic, characterized by intense competition among a collection of local, regional and national participants. In addition to new entrants to the market, we face strong competition from existing supercenters, other brick and mortar food and/or drug retailers, club stores, dollar and discount stores, grocery outlets, online retailers and distributors, specialty and niche supermarkets, drug stores, general merchandisers, wholesale stores, convenience stores, natural food stores, farmers' markets, local chains and stand-alone stores that cater to the individual cultural preferences of specific neighborhoods, restaurants, catering companies and home delivery and meal solution companies. Shifts in the competitive landscape, consumer preference or market share may have an adverse effect on our profitability and results of operations.
As a result of consumers' growing desire to shop online, we also face increasing competition from both our existing competitors that have incorporated the internet as a direct-to-consumer channel and online providers that sell grocery products. Although we have accelerated the expansion of our digital business to offer our customers the ability to shop online for both home delivery and Drive Up & Go curbside pickup, there is no assurance that these online initiatives will continue to be successful. In addition, these initiatives may have an adverse impact on our profitability because of lower gross margins or greater operating costs to compete.
Our ability to attract customers is dependent, in large part, upon a combination of channel preference, location, store conditions, quality, price, service, convenience and selection and our ability to leverage existing and emerging digital technologies. In each of these areas, other companies compete with us and may successfully attract our customers by matching or exceeding what we offer or by providing greater shopping convenience or better offerings. In recent years, many of our competitors have aggressively added locations and adopted a multi-channel approach to marketing and advertising. Our responses to competitive pressures, such as additional promotions, increased advertising, additional capital investment including for development of our digital offerings and retail media network, could adversely affect our profitability and cash flow. We cannot guarantee that our competitive response will succeed in increasing or maintaining our share of retail food sales.
An increasingly competitive industry and inflation and deflation in the prices of certain foods have made it difficult for food retailers to achieve positive identical sales growth on a consistent basis. We and our competitors have attempted to maintain or grow our respective share of retail food sales through capital and price investment, increased promotional activity and new and remodeled stores, creating a more difficult environment to consistently increase year-over-year sales. Some of our primary competitors are larger than us, have greater financial resources available to them or sell a diversified mix of non-food products, and, therefore, may be able to devote greater resources to grow their share of retail food sales or offset lower food margins with higher-margin non-food products. Price investment by our competitors has also adversely affected our operating margins.
Our continued success to effectively compete in the food retail industry is dependent upon our ability to control operating expenses, replicating competitor capabilities, making appropriate investments, managing product and labor costs in an increasingly competitive labor market and health care and pension costs stipulated by our collective bargaining agreements. Several of our primary competitors are larger than we are, or are not subject to collective bargaining agreements, allowing them to more effectively leverage their fixed costs or more easily reduce operating expenses. Changes in our product mix also may negatively affect our profitability. Our inability to adequately control and prevent shrink has impacted our results of operations and could impact our results of operations in the future. Failure to accomplish our objectives could impair our ability to compete successfully and adversely affect our profitability. Profit margins in the food retail industry are low. In order to increase or maintain our profit margins, we develop operating strategies to increase revenues, increase gross margins and reduce costs, such as new marketing programs, new advertising campaigns, productivity improvements, shrink-reduction initiatives, distribution center efficiencies, manufacturing efficiencies, energy efficiency programs and other similar strategies. Our failure to achieve forecasted revenue growth, gross margin improvement or cost reductions could have a material adverse effect on our profitability and operating results.
