Gregg Williams Buy
1,587,301 shares
$1,999,999
@ $1.26
Significance 5/10

Director Gregg Williams buys 1,587,301 shares of VANI at $1.26, now trading 42.7% below 52-week high; 5th VANI purchase in 3 months amid unprofitability.

Gregg Williams, a director at Vivani Medical, purchased 1,587,301 shares at $1.26 for $1,999,999.26, expanding his holdings to 34,531,785 shares (+4.8% net change). This marks the fifth documented insider purchase at VANI in a three-month window (five prior trades at this ticker ranging from 2026-02-15 to 2026-04-15), suggesting persistent accumulation. However, the underlying fundamentals present a significant concern: the company reported zero revenue in the latest quarter and a net loss of $6,780,000 over the most recent full fiscal year, with a current market cap of $94,858,614.40. Williams's prior VANI purchases have shown mixed results—his same-ticker history at VANI shows 1 of 5 prior trades were well-timed at the 90-day mark, and his more recent measurable outcomes were negative (90d returns of -7.1% and -4.0%), contrasting with his cross-ticker track record of a 58.82% win rate. The stock currently trades at $1.10, down 42.7% from its 52-week high of $1.92, raising questions about whether the director's continued buying reflects conviction in an operational turnaround or reflects the stock's depressed absolute price level.

@ $1.07
Significance 4/10

Director Williams Gregg purchases 1,575,231 shares at blended $1.07 (2 transactions) as VANI stock trades -34.8% from 52-week high.

Director Williams Gregg executed 2 separate purchases totaling 1,575,231 shares for $1,683,334.66, increasing his holdings from 29,781,952 to 31,357,183 shares (+5.3%). The buys occurred at $1.03 and $1.26 per share on 2026-03-15, at a blended average of $1.07, while current price stands at $1.22—a position $0.19 above the weighted transaction average but -34.8% below the 52-week high of $1.87. The company reported $0.00 revenue in the latest quarter and net income of $-6,530,000.00, with annual revenue declining -100.0% year-over-year and a market cap of $89,001,726.70. At the same ticker (VANI), Gregg's prior 5 purchases showed mixed results: one measurable 90-day outcome (from 2026-01-27) registered -15.5%, with timing analysis showing 0 of 0 prior buys at this ticker well-timed at the 90-day mark, suggesting no pattern of advantageous entry timing for VANI specifically. His broader cross-ticker track record shows 20 prior buys with a 73.33% 90-day win rate, but this ticker-specific history diverges sharply from his overall record.

Significance 5/10

Director Williams Gregg purchases 1.87M shares (1,866,492) for $2.0M at blended $1.06 avg, expanding stake to 29.78M shares

Director Williams Gregg executed 2 separate purchases totaling 1,866,492 shares for $1,983,333.49 on 2026-02-15, increasing his holdings by 6.7%. The acquisitions occurred at prices ($1.03 and $1.26) near or at the current market level of $1.26, which sits 32.6% below the 52-week high of $1.87. Gregg's cross-ticker track record shows strong historical performance (20 prior buys with 86.67% 90-day win rate and +21.5% average 90-day return), but his same-ticker activity at VANI spans only recent weeks with mixed near-term results and no 90-day measurable outcomes yet. The company is unprofitable (full-year net income of $-6,530,000) with zero latest-quarter revenue and a 100% year-over-year revenue decline, creating a high-risk fundamental backdrop that contrasts with the insider's historical trading success on other securities.

@ $1.48
Significance 6/10

Director Williams Gregg purchased 1,351,351 shares of VANI at $1.48 on 2026-01-27, adding $2.0M to a 27.92M-share position in unprofitable biotech.

Williams Gregg, a director of Vivani Medical, increased his stake by 1,351,351 shares (+5.1%) at $1.48 in late January, investing $1,999,999.48 in aggregate. This marks the fourth consecutive month of open-market purchases at the company, following buys on 2026-01-15, 2025-12-15, and 2025-11-15. His cross-ticker track record shows 92.86% win rate over 90 days with +24.9% average return, suggesting pattern recognition skill, yet this represents an accumulation into a company with $0.00 latest-quarter revenue, $-6,530,000.00 net income, and -100.0% annual revenue growth. At the current price of $1.49, the transaction sits 30.9% below the 52-week high of $1.87 and within the 52-week range, but Gregg's prior trades at VANI lack 90-day measurable outcomes, so no direct timing signal is available at this ticker. The sustained monthly purchases despite deteriorating fundamentals and the absence of positive revenue signal a director willing to accumulate deeply unprofitable equity, a pattern that warrants investor scrutiny of the underlying business case.

Significance 7/10

Director Williams Gregg purchases 1,737,765 shares ($2.0M) at blended $1.14; holdings rise to 26.56M (+7.0%)

Director Williams Gregg executed 2 separate purchases totaling 1,737,765 shares for $1,983,333.94 on 2026-01-15, increasing holdings by 7.0% to 26,564,109 shares. The blended average purchase price of $1.14 sits 16.2% below the current price of $1.36, though the stock trades 27.3% below its 52-week high of $1.87. At the same ticker, Gregg's 4 prior measurable buys show mixed 30-day outcomes (+0.8%, +13.4%, +20.5%, +7.1%), while his cross-ticker track record of 20 prior buys averaged +10.1% return over 30 days and +27.4% over 90 days with a 100% win rate. The company remains materially unprofitable (net income $-6,530,000.00 for the latest period, full-year net income was negative) with zero latest-quarter revenue and annual revenue growth of -100.0%, presenting a stark disconnect between this substantial insider acquisition and the company's operational challenges.

@ $1.23
Significance 3/10

VANI Director Aaron Mendelsohn bought 20,000 shares at $1.23; stock down 34.2% from 52-week high amid -100.0% revenue decline.

Mendelsohn purchased 20,000 shares (20.0K shares) of VANI at $1.23 on 2025-12-29, increasing his holdings by 11.9%. The purchase occurs while the stock trades 34.2% below its 52-week high and after a 19.6% decline over 90 days. Fundamentals remain deeply challenged: the company reported zero revenue in its latest quarter, a -100.0% annual revenue decline, and a net loss of $6,530,000.00 ($-6.5M). Mendelsohn's prior buy at this same ticker on 2023-06-09 resulted in a 90-day loss of -28.4%, a pattern consistent with his broader cross-ticker track record which shows 0% win rate on 1 prior buy with an average 90-day return of -28.4%. The transaction occurs amid continued deterioration in the company's financial trajectory with no clear path to profitability visible in reported metrics.

Significance 7/10

Director Williams Gregg buys 1,737,765 shares (1.74M) at blended avg $1.14, raising stake to 24.83M shares (+7.5%)

Williams Gregg, a director at unprofitable VANI, executed 2 separate purchases totaling 1,737,765 shares for $1,983,333.94 on 2025-12-15 at prices of $1.12 and $1.26. This increased his holdings by 7.5% to 24,826,344 shares. The transaction occurred at prices below the current market price of $1.41, but above the 52-week low of $0.96. While his cross-ticker track record shows strong 90-day performance (30 prior buys, 100% win rate, +30.1% avg), his same-ticker history at VANI shows mixed recent results: three of five prior purchases posted 30-day gains (7.1% to 26.8%), while one declined -16.0%, with 90-day outcomes not yet measurable. The company's fundamentals remain challenged: zero latest-quarter revenue and a $-6,530,000.00 net loss, with annual revenue declining -100.0%. The director's material accumulation warrants investor examination of whether this reflects conviction in a turnaround or routine portfolio management at a highly speculative microcap.

Director Williams Gregg purchased 1,737,764 shares (1.74M) at $1.14 blended average on 2025-11-15, raising stake 8.1% to 23.09M shares

Director Williams Gregg executed 2 separate purchases totaling 1,737,764 shares for $1,983,332.68, at prices of $1.12 and $1.26, with a blended average of $1.14. This increased his holdings by 8.1% to 23,088,579 shares post-transaction. At the current price of $1.47, the shares he purchased are now up 29% from the blended entry, though the stock is -21.4% from its 52-week high and down -13.0% over the past 30 days. Vivani Medical is unprofitable with $-6,530,000 net income in its most recent period and zero revenue in the latest quarter, with annual revenue growth of -100.0%, indicating a company in severe financial distress. Gregg's prior 5 trades at VANI have shown positive 30-day returns (ranging from +4.8% to +26.8%), though 90-day outcomes remain unmeasurable. His cross-ticker track record shows 20 prior buys with a 100% 90-day win rate and average 90-day return of +31.7%, but this context does not transfer to a ticker where the underlying business metrics are deteriorating severely.

Significance 6/10

Director Williams Gregg buys 3,703,703 shares of VANI at $1.62; 21.0% addition to holdings in unprofitable biotech

Director Williams Gregg purchased 3,703,703 shares (3.70M shares) of Vivani Medical at $1.62 on 2025-10-27, increasing his holdings by 21.0% to 21,350,815 shares (21.35M shares). This is a material accumulation in a company with Revenue $0.00 in the latest quarter and an annual revenue decline of -100.0%, though his cross-ticker track record shows a 90d win rate of 93.75% across 20 prior buys with an average 90d return of +29.2%. At VANI specifically, his prior four measurable trades showed positive 30-day returns (ranging +4.8% to +17.9%), with his May 2025 purchase posting +25.7% over 90 days. The stock is currently down 10.7% from its 52-week high but up 16.8% over the past 30 and 90 days, placing this purchase near recent strength rather than a contrarian moment. Investors should note that the company remains unprofitable and revenue-less, and this director's insider confidence must be weighed against the severe operational headwinds and the absence of recent positive fundamentals data.

@ $1.14
Significance 8/10

Director Williams Gregg bought 1.74M VANI shares for $2.0M; 5th buy in 2 months; prior trades all 90d positive.

Williams Gregg, a director, executed 2 separate purchases totaling 1,737,764 shares for $1,983,332.68 at a blended average price of $1.14 on 2025-10-15, increasing his holdings by 10.9% to 17,647,112 shares. This represents his fifth open-market purchase at VANI in approximately two months (after buys on 2025-09-15 and 2025-05-14 through 2025-05-16), establishing a consistent pattern of accumulation despite the company's deteriorating fundamentals: latest quarterly revenue of $0.00, net income of $-7,144,000.00, and annual revenue decline of -100.0%. His prior same-ticker buys demonstrate favorable timing: all three measurable 90-day outcomes (May trades) posted returns of +24.8% to +25.7%, and more recent September purchases achieved 30-day returns of +4.8% and +17.9%. The current price of $1.48 sits 22.3% above the 30-day mark, consistent with his recent pattern of post-buy appreciation. With a cross-ticker track record of 94.44% 90-day win rate and all same-ticker prior outcomes positive at the 90-day mark, this large discretionary accumulation during a period of financial deterioration warrants examination of both the director's private knowledge and the conditions driving his conviction to accumulate at this scale.
