Lam Research Corporation (LRCX) — Earnings Preview

1. Earnings Preview

Key Takeaway: The setup into LRCX’s June quarter print is constructive — consensus sits below the midpoint of guidance on revenue and EPS, creating a low bar — but the stock has already sold off sharply from its June highs, meaning the market is pricing in execution risk rather than a beat, and the single biggest swing factor is whether management raises its WFE outlook above $140B and provides a bullish 2027 framework.

Bar: Consensus revenue of ~$6.69B sits essentially at the midpoint of guidance ($6.60B ± $400M), while consensus EPS of ~$1.70 is modestly above the guided midpoint of $1.65 ± $0.15 — a bar that is neither demanding nor particularly low, but one that Lam has cleared in each of the last several quarters by beating the top end of its own range. The bar is beatable given the company’s track record of conservative guidance.

Guidance/Tone: Management’s posture has been emphatically bullish since the April 22 print, when it raised the 2026 WFE outlook to $140B with an upside bias, guided June-quarter revenue to a record $6.6B, and explicitly stated that second-half revenues would exceed first-half. No post-earnings guidance revision has been issued, so the April call remains the baseline. The tone has not shifted — if anything, peer commentary from ASML (July 15) and KLAC (July 28) has reinforced the demand environment.

Estimate Trajectory: Consensus revenue for the June quarter has drifted modestly higher since the April print ($6.654B on May 1 to $6.690B today), and FY2027 EPS estimates have risen from $7.91 to $8.16 over the same period — a steady upward revision trend that tracks with management’s bullish commentary and peer read-throughs. Revisions are moving with guidance, not diverging, suggesting the gap between consensus and guidance represents cushion rather than risk.

Stock Setup: LRCX has dramatically underperformed since its June 30 peak of ~$433, falling ~38% to ~$270 as of July 29 — a move driven almost entirely by multiple compression (NTM P/E contracted from ~50x to ~35x over the past month) rather than estimate cuts. The stock is now trading at a meaningful discount to its recent range, suggesting the market has already priced in significant risk. A clean beat-and-raise could catalyze a sharp re-rating.

Wildcard: The single biggest wildcard is the WFE outlook update and 2027 framework. KLAC raised its WFE estimate to the “low $150B range” for 2026 (from $140B+) and cited a consensus 2027 WFE view of ~$190B on its July 28 call — if Lam adopts similar language and provides an updated long-term financial model (which management committed to doing later in 2026), the stock could re-rate sharply higher. Conversely, any softening on China or gross margin trajectory would be a negative surprise.

2. KPIs & Consensus Expectations

Key Takeaway: Consensus sits at or just above the midpoint of guidance on all key metrics, creating a low-to-moderate bar that Lam has consistently cleared. Revenue and EPS are the primary swing factors; gross margin trajectory (guided ~50.5%) will be closely watched given management’s commentary that near-term mix headwinds from large-customer concentration will keep margins roughly flat through year-end.

Table 2 — Beat/Miss History (Last 8 Quarters — Top 2 KPIs: Revenue & Operating EPS)

Pattern: Lam has beaten consensus on both revenue and operating EPS in each of the last 8 consecutive quarters, with EPS beats consistently larger than revenue beats (averaging ~5–8% vs. ~2%). This reflects a pattern of conservative guidance and strong operating leverage. Source: Visible Alpha Consensus and Actuals Data.

3. Guidance & Commentary Evolution

Key Takeaway: Guidance has not been formally revised since the April 22 earnings call, but management’s tone has been consistently bullish. No post-earnings 8-K or conference update has changed the numbers; the June-quarter guidance issued on April 22 remains the operative baseline. Peer commentary (ASML, KLAC) since then has reinforced the demand environment.

4. Guidance vs. Estimate Revision Tracker

Key Takeaway: Estimates have drifted modestly higher since the April 22 print on both the June quarter and FY2027, tracking management’s bullish tone. FY2027 EPS has risen ~3.2% since the post-print baseline, reflecting growing conviction in the multi-year WFE upcycle. Estimates are tracking with guidance, not diverging — the gap between consensus and guidance midpoints represents cushion, not risk.

Source: Visible Alpha Consensus and Actuals Data. Post-earnings baseline uses consensus as of April 29, 2026 (approximately 5 trading days after the April 22 print). FY2027 corresponds to Lam’s fiscal year ending June 2027 (VA label FY2027).

Commentary: The steady upward drift in FY2027 estimates (+3.6% on EPS since the post-print baseline) reflects growing sell-side conviction in the multi-year WFE upcycle, consistent with KLAC’s July 28 commentary pointing to a consensus 2027 WFE view of ~$190B. Near-term (FQ4) estimates have been more stable, moving only +0.5–0.8% — appropriate given the explicit guidance range provided by management.

5. Stock Performance

Key Takeaway: LRCX surged ~63% from the April 22 earnings date to its June 30 peak (~$433), dramatically outperforming SOXX (+48%) and SPY (+5%) — driven almost entirely by multiple expansion on WFE upgrade enthusiasm. Since June 30, the stock has reversed sharply (-38% to ~$270 as of July 29), with the selloff driven by multiple compression (NTM P/E from ~50x to ~35x) rather than estimate cuts, creating a potentially attractive entry point ahead of the print.

LRCX vs. SOXX vs. S&P 500 — Indexed to 100 at April 22, 2026 (Last Earnings Date). Sector ETF: iShares Semiconductor ETF (SOXX). Source: Yahoo Finance / Stock Price Data.

Performance Summary (April 22 – July 29, 2026): LRCX +1.5% (indexed: 101.5) vs. SOXX +13.8% (indexed: 113.8) vs. SPY +4.2% (indexed: 104.2). LRCX dramatically outperformed through June 30 (indexed ~163 vs. SOXX ~148 vs. SPY ~105), then reversed sharply in July as the stock gave back its premium. The 12-month performance decomposition shows that the trailing 12-month gain of +178% was driven by ~51% multiple expansion and ~127% earnings growth — but the 1-month reversal of -29% was driven almost entirely by multiple compression (-31%), with estimates essentially unchanged. This suggests the selloff is sentiment/valuation-driven rather than fundamental, and a strong print could catalyze a re-rating.

6. Peer Commentary & Read-Throughs (Last 60 Days)

Key Takeaway: Peer commentary from AMAT, ASML, and KLAC over the past 60 days is uniformly bullish on the WFE demand environment, with all three companies raising outlooks and citing accelerating AI-driven investment in leading-edge logic, DRAM, and advanced packaging — all core Lam markets. KLAC’s July 28 WFE upgrade to ~$150B (from $140B+) is the most directly actionable read-through, as it was issued the day before LRCX’s print and implies Lam may similarly raise its WFE outlook. Note: KLAC’s July 28 commentary was issued the same day as this preview; it addresses KLAC’s forward outlook and 2027 expectations, making it a valid forward-looking read-through.

Methodology Note: Only commentary issued May 29 – July 28, 2026 that addresses the peer’s then-current or future reporting period, or longer-term outlook, is included below. Backward-looking commentary limited to a completed quarter’s results is excluded.

Teradyne (TER) — Q2 2026 Earnings, July 28, 2026

Teradyne reported robust Q2 2026 results on July 28, with EPS of $2.47 (vs. consensus $2.04) and revenue of $1.33B (vs. consensus $1.22B), driven by AI-related semiconductor testing demand. Q3 2026 guidance was issued at revenue of $1.2–1.3B and EPS of $1.85–2.15, well above consensus of $1.46. While Teradyne’s semiconductor test business is distinct from Lam’s etch/deposition focus, the strong beat-and-raise confirms that AI-driven semiconductor demand is broad-based and accelerating across the equipment ecosystem — a positive read-through for LRCX’s June-quarter setup.

7. Material News & Developments

Key Takeaway: The most important development since the April 22 earnings call is the KLAC WFE upgrade to ~$150B on July 28, which implies Lam may similarly raise its 2026 WFE outlook above $140B on the July 29 call — a potential catalyst for re-rating. The sharp stock selloff driven by ASML/China DUV headlines (July 27–28) has created a potentially attractive entry point.

• July 28, 2026 — KLAC Raises WFE Estimate to ~$150B: KLA Corporation reported FQ4 2026 results and raised its 2026 WFE estimate (including advanced packaging) to the “low $150B range,” up from prior $140B+. CEO Rick Wallace cited “unprecedented visibility from customers” and guided for “significant growth in calendar 2027,” with a consensus 2027 WFE view of ~$190B. This is the most directly actionable read-through for LRCX’s July 29 call. Implication: LRCX may raise its own WFE outlook from $140B to $145–150B+, which would be a positive catalyst.
• July 27–28, 2026 — ASML/China DUV Selloff: Reports emerged that a Chinese state-backed firm has begun mass-producing DUV immersion lithography machines, triggering a sharp selloff in semiconductor equipment stocks. ASML fell ~8% and LRCX fell to ~$270 from its recent range of $300–350. J.P. Morgan analyst Sandeep Deshpande characterized the ASML selloff as “seems disproportionate” and “sentiment-driven.” Implication: The selloff appears to be a sentiment/macro event rather than a fundamental change to LRCX’s business; Lam’s etch/deposition tools are not directly threatened by Chinese DUV competition.
• July 15, 2026 — ASML Raises Full-Year Guidance: ASML reported Q2 2026 results with revenue of €9.3B (vs. consensus €8.8B) and raised full-year 2026 guidance to €43–45B (from €36–40B). CEO Christophe Fouquet cited “continuous, very strong demand” and announced plans to increase EUV capacity by 30% in 2027. Implication: ASML’s guidance raise well above all Street estimates confirms the WFE demand environment is stronger than expected — positive for LRCX’s June-quarter results.
• July 8, 2026 — LRCX Announces June-Quarter Conference Call: Lam Research announced its June-quarter financial results conference call for July 29, 2026 at 5:00 PM ET. No pre-announcement or guidance revision was issued alongside the announcement.
• June 25, 2026 — AMAT DRAM & Advanced Packaging Master Class: Applied Materials hosted a master class covering DRAM and advanced packaging technology roadmaps. Key takeaways: DRAM WFE expected to be >2x NAND for the foreseeable future; advanced packaging revenue to exceed $2B in 2026 (>50% growth); panel-level packaging 2–3 years from high volume but equipment selections happening now. Implication: Validates LRCX’s DRAM SAM expansion thesis and panel-level packaging positioning.
• May 2026 — LRCX Opens Panel-Level Packaging Center of Excellence (Salzburg, Austria): Lam opened its Panel-Level Packaging Center of Excellence in Salzburg, Austria (built on the 2022 Semsysco acquisition), signaling a strategic commitment to lead the industry transition from wafer-based to panel-based advanced packaging. Management confirmed active shipments of panel-level solutions. Implication: Positions LRCX ahead of the panel inflection that AMAT and KLAC both identified as a major multi-year growth driver.
• May 14, 2026 — AMAT FQ2 2026 Earnings — Semi Equipment Growth >30%: Applied Materials raised its semiconductor equipment growth outlook to >30% for calendar 2026, citing customers finding new clean room space and increasing orders. Guided H2 2026 equipment revenue at ~$14.5–15B. Implication: Consistent with LRCX’s WFE upgrade to $140B; validates the H2 2026 acceleration thesis.
• April 22, 2026 — LRCX FQ3 2026 Earnings (Baseline): Record revenue of $5.84B (+24% YoY), record EPS of $1.47 (above top of guidance range). June-quarter guidance of $6.60B revenue and $1.65 EPS well above Street expectations. WFE outlook raised to $140B with upside bias. CSBG delivered first-ever $2B+ quarter. Management committed to updating long-term financial model later in 2026.
