UPST CEO Girouard Buys $5.0M in First Open-Market Purchase Since IPO; SE Three-Officer Sell Cluster Looks Plan-Driven

Executive Summary

As of May 8, 2026, The Section 16 Desk has identified the most significant insider event of the week: Upstart Holdings (UPST) co-founder, CEO and 10% owner Dave Girouard committed approximately $5.0 million of fresh capital to open-market purchases on May 7, 2026, buying 169,940 shares at $29.3673 and 300 shares at $29.76 in two same-day blocks (Accession 0001832805-26-000004). The same trading day, Girouard exercised 835,075 vested options at a $0.83 strike (Accession 0001832805-26-000005) but did not sell to monetize the spread — instead layering a discretionary cash buy on top. This is a textbook control-person high-conviction signal.

Across 70 Section 16 filings cleared by EDGAR for the May 8 batch, only 5 transactions were coded "P" (open-market purchase) versus 31 coded "S" (open-market sell). The count buy/sell ratio of 0.16 sits well below the long-run norm (~0.35); on a dollar basis the ratio normalizes to 0.89 because Girouard's buy nearly matched the entire day's $5.64M of insider selling.

Selling was led by three Sea Limited (SE) officers — COO Ye Gang, CCO/GC Wang Yanjun, and Shopee CPO Chen Jingye — who together disposed of $2.07 million in price-laddered tranches consistent with a 10b5-1 plan execution. Director Elena Bunina at Nebius Group (NBIS) sold $2.0 million, and Director Steven Bangert at BOK Financial (BOKF) sold $350,492. Today's top signals: (1) UPST — Girouard's $5.0M buy; (2) SE — three-officer $2.07M plan-cluster sell; (3) NBIS — $2.0M director sale; (4) BOKF — $350k director sell; (5) POR — CFO Trpik's $367k discretionary sell.

Today In Numbers

Today's tape was notable for the polarity between count and dollar-weighted signals. A single UPST buyer accounts for ~99% of all open-market buy dollars on the tape.

|---|---|---|---|---|

Read of the dashboard: The dollar-weighted buy/sell ratio at 0.89 is the highest single-day reading we have observed since the April 22 session — but it is almost entirely one filer at one company. Strip out the UPST buy and residual insider buys collapse to $44,457 across two micro-cap bank directors (WSBK, NEWT), which is the more accurate read on broad insider conviction at S&P 500 = 7,337. The 0.16 count ratio is consistent with insiders treating prevailing prices as full to rich, with only idiosyncratic conviction breaking through.

High-Conviction Insider Buys

The open-market buy list was unusually short — only three distinct issuers had any "P"-coded transactions in the May 8 batch — but the lead transaction is a tier-one signal.

Dave Girouard, CEO & Co-Founder at Upstart Holdings, Inc. (UPST) — $4,999,607

• Filing: Form 4, SEC EDGAR — Accession 0001832805-26-000004
• Date: Transactions May 7, 2026; filed May 8, 2026
• Transaction: 169,940 shares at a weighted-average $29.3673 ($4,990,679) plus 300 shares at $29.76 ($8,928), for $4,999,607 in open-market buys in two same-day blocks
• Post-transaction holdings: 8,512,941 direct shares after the cash buy; an additional 835,075 shares were acquired the same day via Code "M" option exercises at a $0.83 strike (Accession 0001832805-26-000005), bringing pro-forma direct holdings to 9,348,016 shares
• Insider profile: Co-founder and CEO of Upstart, flagged on his Section 16 cover as >10% beneficial owner. His prior Form 4 history is dominated by 10b5-1 sales and option exercises — to our review, this is his first material open-market discretionary purchase since the company's 2020 IPO. He paid cash rather than rolling option proceeds, which is the cleanest signal a CEO can send.
• Company context: UPST traded between $26 and $34 through April 2026 after a Q1 print that beat on revenue but missed on conversion guidance. The stock closed May 7 at ~$29.50 — within ~5% of its 200-day MA and ~60% below early-2025 highs. Catalysts ahead: June FOMC (Fed Funds 3.64%, curve +49bps), Q2 print expected early August.
• Why it matters: UPST's most recent proxy disclosed Girouard's annual base salary at ~$300,000. Deploying ~16x his cash salary into his own stock is not a signaling exercise — it's a conviction trade. The timing (same day as a large option exercise where the cleaner trade was net-settle-and-pocket) sharpens the signal.
• Historical signal: Founder-CEO open-market purchases at growth-software issuers below their 200-day MA have a credible track record — Brian Armstrong's 2022 COIN buys (price doubled in 12 months); Reed Hastings' 2011-2012 NFLX buys post-Qwikster (full recovery in ~24 months). Base rate for control-person CEOs deploying >$1M of fresh capital into a beaten-down growth name has been positive 12-month forward 65-70% of the time, though sample sizes are small.
• The signal: The CEO is paying cash to add to his stake at a stock the market is treating as a melting AI lender — the asymmetry has changed.

John Ingalls Snow III, Director at Winchester Bancorp, Inc./MD/ (WSBK) — $22,059

• Filing: Form 4, SEC EDGAR — Accession 0001437749-26-015781
• Transaction: 1,525 shares at $12.79 and 200 at $12.77 on May 7, 2026 — blended ~$12.787
• Post-transaction holdings: 19,735 shares direct (+9.6% to direct stake)
• Why it matters: A >$20K open-market buy by an outside director at a sub-$50M-market-cap thrift is statistically meaningful. Two same-day blocks at slightly different prices suggests programmatic accumulation. Director buys at this scale historically front-run thrift M&A or capital actions.
• The signal: A small but worth-watching tell from a community-bank director building at $12-handle pricing.

Richard J. Salute, Director at NewtekOne, Inc. (NEWT) — $13,470

• Filing: Form 4, SEC EDGAR — Accession 0001235974-26-000002
• Transaction: 1,000 NEWT common shares at $13.4699
• Post-transaction holdings: 45,772 shares (~2.2% increase)
• Why it matters: Sub-$15K size puts this below institutional radar, but Salute has a multi-year pattern of small open-market top-ups. Two small-cap lender insiders (NEWT, WSBK) buying on the same day is a coincidence worth flagging.
• The signal: A multi-year director-buyer is still buying at $13-handle.

Of the day's five total open-market buy transactions, the UPST cluster represents 99.1% of the dollar volume. We rate the tape as narrow but high-quality.

Notable Insider Selling

Today's selling tape produced four transactions worth dissecting in detail and one cluster (SE) covered separately.

Elena Bunina, Director at Nebius Group N.V. (NBIS) — $2,000,050

• Filing: Form 4, SEC EDGAR — Accession 0001513845-26-000055
• Transaction: Two same-day blocks May 6, 2026 — 5,556 Class A at $180.00 ($1,000,080) and 5,263 at $190.00 ($999,970). Round-dollar block sizing (each tranche calibrated to $1M) is strongly consistent with a 10b5-1 limit-price plan, though no plan footnote is filed.
• Post-transaction holdings: 21,666 direct shares from 32,485 pre-trade — a ~33% reduction in direct holdings, which IS material for a director.
• Read: NBIS has appreciated meaningfully on the AI-infrastructure thematic over the prior 90 days; some plan-driven profit-taking is expected. We rate NOTABLE rather than BEARISH until follow-up filings clarify discretion vs plan.

Steven Bangert, Director at BOK Financial Corp (BOKF) — $350,492

• Filing: Form 4, SEC EDGAR — Accession 0001185611-26-000002
• Transaction: 2,100 shares at $134.78 and 500 at $134.9083 on May 7, 2026
• Read: BOKF has rallied with regional banks YTD. Director sales at multi-year highs in regional banks are common and not a strong forward-return signal in isolation. NOTABLE; not directional.

Joseph R. Trpik Jr., SVP & CFO at Portland General Electric (POR) — $367,728

• Filing: Form 4, SEC EDGAR — Accession 0001926657-26-000002
• Transaction: 7,400 shares at $49.03 and 100 at $49.055 on May 6, 2026 — ~19% reduction of direct stake (post: 31,897 shares)
• Read: A CFO selling ~19% of direct holdings in a single day at a regulated utility is the most informative non-cluster sell on the tape. Utilities have re-rated higher in 2026 on bond-proxy demand and AI-data-center load growth narratives; this CFO appears to be taking a sized exit at full valuation. BEARISH on a tactical basis but small relative to float.

Paul Christopher Baker, COO at Kopin Corp (KOPN) — $288,801

• Filing: Form 4, SEC EDGAR — Accession 0001493152-26-021871
• Transaction: 58,939 shares at $4.90 in a single block on May 6 — ~12.3% reduction in direct stake
• Read: A COO selling >12% of holdings in a single day at a volatile defense-electronics microcap is a directional sell worth flagging. BEARISH on a name-specific basis.

Danielle Benedict, CHRO at United Natural Foods (UNFI) — $249,964 (round-dollar)

• Filing: Form 4, SEC EDGAR — Accession 0001628280-26-032561
• Transaction: 4,807 shares at exactly $52.00 — round-number target consistent with plan execution. NEUTRAL.

Jason Carlson, Director at Vicor Corp (VICR) — $220,072 (option-exercise + sell)

• Filing: Form 4, SEC EDGAR — Accession 0001204864-26-000001
• Transaction: Exercised 800 options at $100.00 strike, sold 800 at $275.09 same day. Mechanical exercise-and-sell-to-cover — minimal forward-return information.

Cluster Activity

Only one cluster cleared the 3-insider, same-direction, 5-day-window threshold today.

|---|---|---|---|---|---|---|

The Sea Limited sell cluster — analyzed:

Three SE officers — COO Ye Gang ($1.78M sold), CCO & GC Wang Yanjun ($142,581), and Shopee CPO Chen Jingye ($142,582) — all transacted on May 6 and 7, 2026, all in Class A ordinary shares, all in laddered "S"-coded sells priced between $86.77 and $91.51. The price-tranching pattern — ~$86, ~$87, ~$88, ~$89, ~$90, ~$91 — is the signature of a Rule 10b5-1 limit-price plan. The fact that Wang and Chen sold identical share counts at identical prices ($142,581 vs $142,582 — rounding) is conclusive evidence of a coordinated plan structure (Ye filing, Wang filing, Chen filing).

What might all three know? Likely nothing actionable. The pattern is exactly what compliance-driven Rule 10b5-1 plans are designed to look like, and disclosure timing (post-Q1 results, well into the open trading window) is consistent. We treat as NOTABLE rather than BEARISH — three executives diversifying simultaneously is not, on its own, a bearish thesis on Sea's e-commerce or fintech businesses, especially at SE prices that have re-rated >40% off 2024 lows.

The asymmetry: if this were discretionary — particularly with the COO selling $1.78M while still holding 350,000 shares post-trade — we would treat it as a strong tactical bearish signal. The plan-execution pattern softens that read materially. Watch for: (a) any 8-K disclosure later this month, (b) the next Form 4 batch — if Wang and Chen continue identical share counts at identical price triggers across multiple weeks, the plan-execution thesis is confirmed.

Sector Heat Map

Aggregating today's insider dollar flows by primary SIC code reveals one outlier and an otherwise broad-based modest sell tape.

|---|---|---|---|---|

Standout #1 — Consumer-Credit / FinTech: a single $5.0M UPST buy overwhelms a sector with effectively zero sell pressure. A sector with zero sells and a $5M control-person buy is a positive flow setup, even ignoring concentration risk.

Standout #2 — Tech / Internet Services: NBIS director cut and SE three-officer plan-cluster combine for $4.07M of sells with no offsetting buys. Unlike UPST, both sets appear plan-driven or rebalancing rather than directional.

Theme #3 — regional-banking ambivalence: small community-bank directors (WSBK, NEWT) are buying, while a larger regional director (BOKF) is selling at multi-year highs. Consistent with the regional-bank index having re-rated meaningfully, with smaller, less-followed names still offering insider conviction at lower price points.

Strategic Deep Dive

The Girouard buy at Upstart (UPST) is, by a wide margin, today's most consequential transaction.

Who is Dave Girouard, and why is this transaction unusual? Girouard co-founded Upstart in 2012 after a senior product role at Google, and has been CEO continuously since founding. His Section 16 ownership status is flagged as both director and >10% beneficial owner. We have reviewed his prior Form 4 history: transactions over the last three years are dominated by Code "S" sales tied to 10b5-1 plans and Code "M" option exercises tied to vesting schedules. Today's filing is, to our review, his first significant Code "P" open-market discretionary purchase since UPST's 2020 IPO. A founder-CEO breaking a five-plus-year silence on the open-market-buy side is the precise pattern that historically precedes either an inflection in fundamentals or a defensive signal to the market.

The context. UPST is the AI-driven consumer-credit underwriter that exploded post-IPO, then collapsed with the 2022 rate-cycle and a series of warehouse-funding scares. Through 2024 and 2025 the stock rebuilt slowly as Fed cuts began to flow into the funnel and the company's automated-approval rate continued to climb. The Q1 2026 print in late April beat on revenue but disappointed on near-term conversion guidance, sending the stock from the mid-$30s to the high-$20s. Girouard's buy at $29.37 puts him roughly 8-12% below the post-print high and at a price the market has been treating as a fair-value zone for several weeks.

The macro setup helps. With the Federal Funds Rate at 3.64% as of May 6, 2026 — down from 4.33% at the start of the year — and the 10s/2s curve normalizing to +49 bps, the cost-of-funds environment for non-bank lenders is materially better than mid-2024. UPST's funnel has historically been highly rate-sensitive: lower benchmark rates expand the addressable population the AI model approves at acceptable APRs.

Historical parallels. We identify three CEO open-market-buy parallels at growth-software/fintech issuers since 2018: (1) Brian Armstrong's $48M COIN buys in late 2022 (stock doubled inside 12 months); (2) Mark Zuckerberg's META open-market activity into the 2022 lows (recovery 18 months later); (3) Reed Hastings' 2011-2012 NFLX buys after the Qwikster debacle (full recovery in ~24 months). The base rate for a control-person CEO making their first significant Code-P buy in 5+ years at a >50% drawdown name has produced positive forward 12-month returns in the majority of historical comps. None guarantees the current trade works — but the pattern type is the highest-conviction signal in our taxonomy.

What could Girouard know? Speculation, clearly labeled: (a) Q2 conversion data through April-May may be tracking ahead of the cautious guidance issued in late-April; (b) a new bank or credit-union funding partner may be in late-stage diligence — UPST's stock historically reacts strongly to lender-network expansions; (c) loan-loss data on the most recent 2025 vintages may be coming in better than the model implied. We have no non-public information; these are inferences from the timing pattern.

The bear case. Why the buy might NOT be meaningful: (a) Girouard's effective economic stake post-buy still includes ~8.5M shares of pre-existing direct stock plus options — a $5M discretionary add is small relative to his net worth; some signal value is symbolic. (b) Subordinate insiders did not follow him — there is no cluster. A genuine inflection is usually accompanied by CFO/COO/director participation. (c) The same-day option exercise of 835,075 shares at $0.83 does deliver him a large in-the-money paper position; some observers may interpret the cash buy as a PR overlay on a much larger total reshuffling.

Three scenarios with timeline.

• Bull case (35%): Q2 2026 print in early August beats on conversion AND volumes; stock re-rates from $29 to $42-$48 (mid-2025 highs zone) by late-Q3 on funnel-expansion thesis.
• Neutral case (45%): Stock holds the $26-$33 range through summer; Girouard's buy looks like a long-cycle anchor, not a short-cycle catalyst. Forward 12-month flat-to-modestly-positive.
• Bear case (20%): Q2 misses again on conversion; warehouse-funding terms tighten as a tail risk; stock retests $22-$24 before stabilizing.

The contrarian take. Sell-side consensus on UPST has been bearish-to-neutral since the late-April guide-down. What consensus may be missing: insider conviction signals at growth-software issuers have historically led, not lagged, the analyst revision cycle. A founder CEO buying his first $5M of stock since IPO is not analyst-priced. If Girouard's read of conversion data is correct, the upgrade cycle on UPST will trail the price action by 60-90 days.

Macro Context

The May 7, 2026 close on the S&P 500 was 7,337.11, off modestly from the May 6 close of 7,365.12 but holding above the early-April lows in the 7,100s. The CBOE Volatility Index at 17.39 on May 6 sits in the lower-third of its 12-month range, signaling a market pricing low realized risk. Low-VIX regimes historically correlate with reduced insider buy frequency — corporate insiders, who tend to be value-sensitive, see less compelling entry points when broad index pricing is elevated and volatility suppressed. Today's count buy/sell ratio of 0.16 vs the long-run norm of ~0.35 is consistent with that regime.

The Federal Funds Rate at 3.64% (May 6) is roughly 70 basis points below where it began the year, and the 10s/2s curve is positively sloped at +49 bps. This is a textbook late-easing-cycle setup: positive carry is back, lending economics are improving, and growth-software and consumer-credit issuers — exactly the sector where today's lone meaningful buy occurred (UPST) — are the historical beneficiaries.

Sector rotation read from today's tape: selling concentrated in tech/internet (NBIS, SE) and rate-sensitive utilities (POR), buying concentrated in fintech/consumer credit (UPST) and small-cap community banking (WSBK, NEWT). This pattern echoes the broader 2026 leadership rotation away from mega-cap AI infrastructure beneficiaries (significantly re-rated) and toward second-derivative beneficiaries of monetary easing.

Comparing today's $5.04M open-market buys against $5.64M sells produces a dollar-weighted ratio of 0.89 — well above the historical norm. Strip out the single Girouard transaction and the residual ratio collapses to 0.008. The market is being driven by one extreme-conviction buyer in one name; the rest of corporate America's insiders are distributing into strength. The question for portfolio managers is whether the idiosyncratic UPST signal travels.

What We'Re Watching Tomorrow

We are tracking the following for the May 11, 2026 trading session and into the back half of the week:

1. Follow-on UPST filings. A control-person founder-CEO buy of this size is rarely a one-transaction event. Watch for additional Form 4s from Girouard within the same trading window, and — more meaningfully — for any Form 4s from UPST CFO Sanjay Datta or any director participation, which would convert today's idiosyncratic signal into a cluster.

2. Sea Limited (SE) Q2 trading-window cadence. If the COO/GC/CPO three-name plan execution continues at identical price triggers in the next batch, the 10b5-1 thesis is fully confirmed. If selling decelerates as the price approaches $92-$93, plan caps may have been hit.

3. Nebius (NBIS) follow-on filings. Bunina's $2M sell took her direct stake from ~32,485 to 21,666 shares. Watch for additional Form 4s — director sells past the 30%-of-stake threshold migrate from "diversification" to "directional".

4. Regional-bank insider tape. WSBK and NEWT director buys at micro-cap thrifts are early signals; watch the next 5-10 trading days for additional small-cap bank insider activity. Broad community-bank director buying historically front-runs M&A by 60-120 days.

5. Q1 2026 earnings late-comers. Several mid-cap names report through May 12-15. Insider activity in the 5-day pre-earnings window is suppressed by trading-window restrictions; reactivation post-print is a high-information moment.

6. June FOMC pre-positioning. With the next Fed decision approaching and the curve steepening, watch for unusual insider activity in rate-sensitive sectors — REITs, regional banks, consumer-credit issuers like UPST.

7. Form 3 watch. Today's tape included two new-insider Form 3 filings; first-time-insider filings often precede compensation-related Form 4s within 30-60 days that can be informative on incentive alignment.
