Tesco Share Price: Headed For Another Decade High?

Tesco's share price has reached decade highs, bolstered by significant market share gains to a record 28.4% and reaccelerated sales growth. Ahead of its interim results, the market anticipates an upgrade to the lower bound of its FY25 adjusted EBIT guidance, as initial concerns over labor costs and competition from ASDA have largely dissipated. While strong H1 revenue is expected, the analyst projects adjusted EBIT slightly below consensus, with further stock appreciation contingent on beating expectations and a narrower, higher full-year guidance. However, much of the future growth is considered priced in, suggesting limited upside from a valuation standpoint without sustained margin expansion.

Analysis

Tesco (LON:TSCO) is approaching its interim results from a position of strength, with its share price at decade highs, underpinned by significant operational momentum. The company has expanded its market share by 0.7% to a record 28.4%, according to Kantar, and reaccelerated sales growth to 7.7%. Initial full-year adjusted EBIT guidance of £2.7-£3.0 billion, which was considered conservative, is now widely expected to be upgraded at the lower bound by at least £100 million. This optimism stems from the dissipation of earlier concerns, as the competitive threat from ASDA has failed to materialize, evidenced by ASDA's 18 consecutive months of negative sales. For the upcoming H1 results, strong revenue growth is anticipated across the UK (+6.1%) and Ireland (+7.2%), though projected adjusted EBIT of £1.52 billion is slightly below market consensus of £1.56 billion and the prior year's £1.65 billion. Despite this strong performance, further share price appreciation is contingent on beating consensus and, more critically, providing upwardly revised guidance. However, the potential for a significant guidance upgrade is viewed as unlikely due to macroeconomic uncertainties such as the Budget and potential tax hikes. The prevailing view is that much of the positive outlook is already priced into the stock, suggesting limited valuation upside without further evidence of sustained margin expansion and market share growth.

Key Decisions for Investors

• Given the stock's run to decade highs, investors should recognize that a failure to at least meet consensus earnings expectations could trigger a near-term price correction.
• The primary catalyst for further upside is an upgrade to full-year guidance; specifically, a narrowing of the adjusted EBIT range to above £2.80 billion would be a strong bullish signal, though it is not the base-case expectation.
• With strong performance largely priced in, consider that valuation may be stretched, and look for evidence of sustained margin expansion and continued market share gains in coming months before increasing exposure.
• Monitor management commentary on consumer resilience, particularly any signs of trading up to higher-margin private label lines like 'Tesco Finest', as this is a key indicator for future margin health.
