Tompkins Mark N.

10% owner Mark N. Tompkins sold 95,000 shares (95.0K shares) for $1,534,584.51 across 5 transactions, reducing stake by 4.9%; stock down 11.0% in 30 days and -34.1% from 52-week high.

Mark N. Tompkins, a 10% owner, executed 5 separate sales totaling 95,000 shares for $1,534,584.51 between 2026-01-29 and 2026-02-02 at prices ranging from $15.74 to $17.16, with a blended average price of $16.15. His holdings fell from 1.92M shares to 1.82M shares, a reduction of 4.9%. The timing is notable: the sales occurred as ALMU stock has declined 11.0% over the past 30 days and sits 34.1% below its 52-week high of $24.04, despite revenue growth of 407.9% year-over-year. However, the company remains unprofitable (net income of $-1,493,000.00 in the latest quarter), and his cross-ticker track record shows a 90d well-timed rate of 0.00%, indicating his prior sells across other stocks have not typically preceded further declines. Recent prior sales at ALMU (five trades on 2026-01-21 and 2026-01-22) outcomes are not yet measurable, leaving no data to assess whether this insider's recent activity at this specific ticker has been predictive.

10% Owner Tompkins Mark N. sold 105,000 shares of ALMU across 8 transactions for $2.0M in Jan 2026, reducing stake by 5.2%

Mark N. Tompkins, a 10% owner of Aeluma Inc., executed 8 separate sales totaling 105,000 shares for $2.0M between January 20–22, 2026, at a blended average price of $19.14, reducing his holdings from 2.02M to 1.92M shares. His recent prior sales at ALMU (5 trades in early-to-mid December 2025) all resulted in subsequent 30-day gains ranging from +14.8% to +50.2%, suggesting a pattern of selling ahead of rallies. The current price of $17.65 is -26.6% from the 52-week high of $24.04 and below the transaction prices achieved last week, indicating the stock has declined materially since these sales. ALMU's fundamentals remain challenged: the company posted negative net income of $-1.5M in the latest quarter on revenue of $1.4M and remains unprofitable on a full-year basis, though annual revenue growth was +407.9%.

10% owner Tompkins sold 85,000 shares across 3 days (Dec 18–22) at $14.37–$14.83 for $1.2M; stock -38.1% from 52-week high, company unprofitable.

Tompkins Mark N., a 10% owner at Aeluma, Inc., executed 3 separate sales totaling 85,000 shares for $1,247,450.00 over three trading days (Dec 18–22, 2025) at prices ranging from $14.37 to $14.83, reducing his holdings by 3.9% from 2.17M to 2.08M shares. The selling occurred within a context of significant price weakness: the stock is -38.1% from its 52-week high of $24.04, though it has recovered +17.7% over the prior 30 days. Aeluma reported negative net income of $-1,493,000.00 on revenue of $1,385,000.00 (latest quarter) and was unprofitable over its most recent full fiscal year, though annual revenue growth reached +407.9%. The insider's cross-ticker track record shows 20 prior sells with an average 30-day return of -24.8%, while his 5 prior trades at ALMU remain unmeasurable in outcome (all within the past two weeks).

10% owner Mark N. Tompkins sells 100,000 shares across 6 transactions for $1.6M (avg $16.08) amid unprofitable operations.

Mark N. Tompkins, a 10% owner, executed 6 separate sales totaling 100,000 shares for $1,607,595.74 (blended average price $16.08) between December 4–8, 2025, reducing his stake by 4.3% to 2,219,988 shares. The sales occurred at prices below the current market level ($17.09), and notably within weeks of his prior sell activity (5 prior trades at ALMU between October 16–20, 2025), all of which posted negative 30-day returns (-18.5% to -31.6%). Aeluma is currently unprofitable (net income $-1,493,000.00 over its most recent full fiscal year) despite strong revenue growth (+407.9% year-over-year), trading -28.9% from its 52-week high. The recurring sales pattern and magnitude of the liquidation, combined with the company's negative profitability trajectory, warrant investor scrutiny of whether cash flow pressures or conviction shifts may be driving this sustained divestment activity.

10% owner Tompkins Mark N. sold 77,500 shares ($1.3M) at ALMU across 4 transactions on 10-17 and 10-20, reducing stake -3.2%.

Mark N. Tompkins, a 10% owner at Aeluma, executed 4 separate sales totaling 77,500 shares for $1,291,919.36 across 2025-10-17 and 2025-10-20, at prices ranging from $16.39 to $18.45 with a blended average of $16.67. The stock now trades at $16.18, down 32.7% from its 52-week high of $24.04 and off 17.0% over the last 30 days, indicating a sharp deterioration in valuation post-sale. His holdings declined by 3.2% (from 2.40M to 2.32M shares), representing a meaningful but not complete portfolio exit. Notably, Tompkins conducted 5 prior sales at ALMU on 2025-10-15 and 2025-10-16 (the day before this filing's first tranche), establishing a pattern of sustained sales over a three-day window; outcomes on those earlier trades are not yet measurable. The company reported strong recent revenue growth (407.9% annual increase) and profitability in the latest quarter ($1.5M net income), but this masks a negative full-year result, creating a mixed financial picture that complicates interpretation of the sale's intent.

10% Owner Tompkins sells 65,000 shares for $1.3M across 5 sales at $20.09 average; stock now at $16.70

Tompkins Mark N., a 10% owner, executed 5 separate sales totaling 65,000 shares (65.0K shares) for $1,305,674.60 ($1.3M) on 2025-10-15 and 2025-10-16, at a blended average price of $20.09. The current market price of $16.70 is -30.5% from the 52-week high of $24.04, placing the stock under pressure. The company's most recent quarter showed revenue of $1,254,966.00 ($1.3M) and net income of $1,460,893.00 ($1.5M), but importantly, the company was unprofitable over its most recent full fiscal year, despite annual revenue growth of +407.9%. Post-transaction, Tompkins retains 2,397,488 shares (2.40M shares), a reduction of 65,000 shares (-2.6% vs pre-transaction holdings). The insider's prior same-ticker history at ALMU shows 5 prior trades, all recent and with outcomes not yet measurable; across his broader cross-ticker track record, there are 20 prior sells.

10% owner Tompkins Mark N. sold 107,186 shares for $1.9M across 5 transactions Oct 10–14, blended at $17.87, retaining 2.46M shares.

Tompkins, a 10% owner of Aeluma, executed five separate sales totaling 107,186 shares (107.2K shares) for $1,915,158.65 ($1.9M) over a three-day window (Oct 10–14, 2025), with prices ranging from $16.60 to $19.86 and a blended average price of $17.87. The stock now trades at $19.72, down 18.0% from its 52-week high of $24.04 but up 27.7% over the trailing 30 days, suggesting recent momentum. Post-transaction, Tompkins retains 2.46M shares (2,462,488 shares), representing a 4.2% reduction in his prior stake. The company reported latest-quarter revenue of $1.3M and net income of $1.5M, though it was unprofitable over its most recent full fiscal year, and shows sharp annual revenue growth of +407.9%, marking a high-growth yet profitability-challenged profile. With five prior sales at this ticker all executed within the last few days and no measurable historical timing outcomes yet available, the clustering of sales warrants investor attention to whether this reflects a deliberate, multi-tranche program or opportunistic execution.

10% Owner Mark N. Tompkins sold 106,908 shares (106.9K) over 3 days for $1.8M at blended $17.25; stock now $16.50, down 9.3% in 30 days

Mark N. Tompkins, a 10% owner at Aeluma, filed 7 separate sales totaling 106,908 shares for $1,844,012.72 across October 7–9, 2025, at prices ranging from $16.54 to $19.16 with a blended average of $17.25. The current share price of $16.50 sits 31.4% below the 52-week high of $24.04 and has declined 9.3% over the past 30 days, though it remains up 5.6% over 90 days. This represents a 4.0% reduction in Tompkins' holdings, leaving him with 2,569,674 shares post-transaction. The company reported strong fundamental growth—annual revenue growth of +407.9% year-over-year and recent quarterly net income of $1,460,893.00—though it was unprofitable on a full-year basis. Tompkins' prior five sales at this ticker all occurred within the immediately preceding days (October 2–6), establishing a pattern of consecutive daily dispositions that warrants observation against future price movement and the company's forward earnings trajectory.

10% Owner Tompkins sold 129,751 shares for $2.3M at $18.00 avg; 5 prior sales in 5 days

Tompkins Mark N., a 10% owner, executed 5 separate sales totaling 129,751 shares for $2,335,088.62 over a 5-trading-day span (Oct 1–6, 2025), reducing his holdings by 4.6% to 2,676,582 shares. The blended average price of $18.00 sits below the current price of $18.47 but well below the 52-week high of $24.04, indicating these sales occurred as the stock had already retreated 23.2% from its recent peak. The pattern of 5 consecutive daily or near-daily sales is notable—this clustering follows 4 prior sales at ALMU in the preceding 2 days (Sept 29–30), suggesting sustained, deliberate liquidation rather than an isolated transaction. Given the company's recent profitability in the latest quarter (net income $1,460,893.00) yet full-year unprofitability, the context is mixed; however, the rapid succession and scale of sales—totaling nearly $2.35 million from a single 10% shareholder—merit monitoring for signals of insider appetite.

10% owner Tompkins sold 109,080 shares across 6 transactions (Sept 29–Oct 1) for $1,834,643.38 at blended $16.82 avg; stock now at $16.85, down -29.9% from 52-week high.

Tompkins Mark N., a 10% owner, executed six separate sales totaling 109,080 shares for $1,834,643.38 between September 29 and October 1, 2025, at prices ranging from $16.18 to $18.36. The timing is notable: stock prices have fallen 16.7% over the past 30 days and 29.9% from the 52-week high of $24.04, suggesting the sales occurred in a downtrend. Post-transaction, Tompkins retains 2,806,333 shares (2.81M shares), representing a -3.7% reduction in holdings. While Aeluma shows strong near-term fundamentals—latest quarterly revenue of $1,254,966.00 ($1.3M) and net income of $1,460,893.00 ($1.5M)—these figures must be contextualized against the company's unprofitability over the most recent full fiscal year, despite 407.9% annual revenue growth. The concentrated sale activity by a major shareholder during a pronounced price decline warrants investor attention to underlying business momentum and near-term cash-flow sustainability.
